+# NEWS for rsync 3.2.7 (20 Oct 2022)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+- Fixed the client-side validating of the remote sender's filtering behavior.
+
+- More fixes for the "unrequested file-list name" name, including a copy of
+  "/" with `--relative` enabled and a copy with a lot of related paths with
+  `--relative` enabled (often derived from a `--files-from` list).
+
+- When rsync gets an unpack error on an ACL, mention the filename.
+
+- Avoid over-setting sanitize_paths when a daemon is serving "/" (even if
+  "use chroot" is false).
+
+### ENHANCEMENTS:
+
+- Added negotiated daemon-auth support that allows a stronger checksum digest
+  to be used to validate a user's login to the daemon.  Added SHA512, SHA256,
+  and SHA1 digests to MD5 & MD4.  These new digests are at the highest priority
+  in the new daemon-auth negotiation list.
+
+- Added support for the SHA1 digest in file checksums.  While this tends to be
+  overkill, it is available if someone really needs it.  This overly-long
+  checksum is at the lowest priority in the normal checksum negotiation list.
+  See [`--checksum-choice`](rsync.1#opt) (`--cc`) and the `RSYNC_CHECKSUM_LIST`
+  environment var for how to customize this.
+
+- Improved the xattr hash table to use a 64-bit key without slowing down the
+  key's computation.  This should make extra sure that a hash collision doesn't
+  happen.
+
+- If the `--version` option is repeated (e.g. `-VV`) then the information is
+  output in a (still readable) JSON format.  Client side only.
+
+- The script `support/json-rsync-version` is available to get the JSON style
+  version output from any rsync.  The script accepts either text on stdin
+  **or** an arg that specifies an rsync executable to run with a doubled
+  `--version` option.  If the text we get isn't already in JSON format, it is
+  converted. Newer rsync versions will provide more complete json info than
+  older rsync versions. Various tweaks are made to keep the flag names
+  consistent across versions.
+
+- The [`use chroot`](rsyncd.conf.5#) daemon parameter now defaults to "unset"
+  so that rsync can use chroot when it works and a sanitized copy when chroot
+  is not supported (e.g., for a non-root daemon).  Explicitly setting the
+  parameter to true or false (on or off) behaves the same way as before.
+
+- The `--fuzzy` option was optimized a bit to try to cut down on the amount of
+  computations when considering a big pool of files. The simple heuristic from
+  Kenneth Finnegan resuled in about a 2x speedup.
+
+- If rsync is forced to use protocol 29 or before (perhaps due to talking to an
+  rsync before 3.0.0), the modify time of a file is limited to 4-bytes.  Rsync
+  now interprets this value as an unsigned integer so that a current year past
+  2038 can continue to be represented. This does mean that years prior to 1970
+  cannot be represented in an older protocol, but this trade-off seems like the
+  right choice given that (1) 2038 is very rapidly approaching, and (2) newer
+  protocols support a much wider range of old and new dates.
+
+- The rsync client now treats an empty destination arg as an error, just like
+  it does for an empty source arg. This doesn't affect a `host:` arg (which is
+  treated the same as `host:.`) since the arg is not completely empty.  The use
+  of [`--old-args`](rsync.1#opt) (including via `RSYNC_OLD_ARGS`) allows the
+  prior behavior of treating an empty destination arg as a ".".
+
+### PACKAGING RELATED:
+
+- The checksum code now uses openssl's EVP methods, which gets rid of various
+  deprecation warnings and makes it easy to support more digest methods.  On
+  newer systems, the MD4 digest is marked as legacy in the openssl code, which
+  makes openssl refuse to support it via EVP.  You can choose to ignore this
+  and allow rsync's MD4 code to be used for older rsync connections (when
+  talking to an rsync prior to 3.0.0) or you can choose to configure rsync to
+  tell openssl to enable legacy algorithms (see below).
+
+- A simple openssl config file is supplied that can be installed for rsync to
+  use.  If you install packaging/openssl-rsync.cnf to a public spot (such as
+  `/etc/ssl/openssl-rsync.cnf`) and then run configure with the option
+  `--with-openssl-conf=/path/name.cnf`, this will cause rsync to export the
+  configured path in the OPENSSL_CONF environment variable (when the variable
+  is not already set).  This will enable openssl's MD4 code for rsync to use.
+
+- The packager may wish to include an explicit "use chroot = true" in the top
+  section of their supplied /etc/rsyncd.conf file if the daemon is being
+  installed to run as the root user (though rsync should behave the same even
+  with the value unset, a little extra paranoia doesn't hurt).
+
+- I've noticed that some packagers haven't installed support/nameconvert for
+  users to use in their chrooted rsync configs.  Even if it is not installed
+  as an executable script (to avoid a python3 dependency) it would be good to
+  install it with the other rsync-related support scripts.
+
+- It would be good to add support/json-rsync-version to the list of installed
+  support scripts.

+
+# NEWS for rsync 3.2.6 (9 Sep 2022)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+- More path-cleaning improvements in the file-list validation code to avoid
+  rejecting of valid args.
+
+- A file-list validation fix for a [`--files-from`](rsync.1#opt) file that ends
+  without a line-terminating character.
+
+- Added a safety check that prevents the sender from removing destination files
+  when a local copy using [`--remove-source-files`](rsync.1#opt) has some files
+  that are shared between the sending & receiving hierarchies, including the
+  case where the source dir & destination dir are identical.
+
+- Fixed a bug in the internal MD4 checksum code that could cause the digest
+  to be sporadically incorrect (the openssl version was/is fine).
+
+- A minor tweak to rrsync added "copy-devices" to the list of known args, but
+  left it disabled by default.
+
+### ENHANCEMENTS:
+
+- Rename `--protect-args` to [`--secluded-args`](rsync.1#opt) to make it
+  clearer how it differs from the default backslash-escaped arg-protecting
+  behavior of rsync.  The old option names are still accepted.  The
+  environment-variable override did not change its name.
+
+### PACKAGING RELATED:
+
+- The configure option `--with-protected-args` was renamed to
+  `--with-secluded-args`.  This option makes `--secluded-args` the default
+  rsync behavior instead of using backslash escaping for protecting args.
+
+- The mkgitver script now makes sure that a `.git` dir/file is in the top-level
+  source dir before calling `git describe`. It also runs a basic check on the
+  version value. This should avoid using an unrelated git description for
+  rsync's version.
+
+### DEVELOPER RELATED:
+
+- The configure script no longer sets the -pedantic-errors CFLAG (which it
+  used to try to do only for gcc).
+
+- The name_num_obj struct was modified to allow its dynamic name_num_item list
+  to be initialized in a better way.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.2.5 (14 Aug 2022)
+
+## Changes in this version:
+
+### SECURITY FIXES:
+
+- Added some file-list safety checking that helps to ensure that a rogue
+  sending rsync can't add unrequested top-level names and/or include recursive
+  names that should have been excluded by the sender.  These extra safety
+  checks only require the receiver rsync to be updated.  When dealing with an
+  untrusted sending host, it is safest to copy into a dedicated destination
+  directory for the remote content (i.e. don't copy into a destination
+  directory that contains files that aren't from the remote host unless you
+  trust the remote host). Fixes CVE-2022-29154.
+
+ - A fix for CVE-2022-37434 in the bundled zlib (buffer overflow issue).
+
+### BUG FIXES:
+
+- Fixed the handling of filenames specified with backslash-quoted wildcards
+  when the default remote-arg-escaping is enabled.
+
+- Fixed the configure check for signed char that was causing a host that
+  defaults to unsigned characters to generate bogus rolling checksums. This
+  made rsync send mostly literal data for a copy instead of finding matching
+  data in the receiver's basis file (for a file that contains high-bit
+  characters).
+
+- Lots of manpage improvements, including an attempt to better describe how
+  include/exclude filters work.
+
+- If rsync is compiled with an xxhash 0.8 library and then moved to a system
+  with a dynamically linked xxhash 0.7 library, we now detect this and disable
+  the XX3 hashes (since these routines didn't stabilize until 0.8).
+
+### ENHANCEMENTS:
+
+- The [`--trust-sender`](rsync.1#opt) option was added as a way to bypass the
+  extra file-list safety checking (should that be required).
+
+### PACKAGING RELATED:
+
+- A note to those wanting to patch older rsync versions: the changes in this
+  release requires the quoted argument change from 3.2.4. Then, you'll want
+  every single code change from 3.2.5 since there is no fluff in this release.
+
+- The build date that goes into the manpages is now based on the developer's
+  release date, not on the build's local-timezone interpretation of the date.
+
+### DEVELOPER RELATED:
+
+- Configure now defaults GETGROUPS_T to gid_t when cross compiling.
+
+- Configure now looks for the bsd/string.h include file in order to fix the
+  build on a host that has strlcpy() in the main libc but not defined in the
+  main string.h file.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.2.4 (15 Apr 2022)
+
+## Changes in this version:
+
+### BEHAVIOR CHANGES:
+
+ - A new form of arg protection was added that works similarly to the older
+   `--protect-args` ([`-s`](rsync.1#opt)) option but in a way that avoids
+   breaking things like rrsync (the restricted rsync script): rsync now uses
+   backslash escaping for sending "shell-active" characters to the remote
+   shell. This includes spaces, so fetching a remote file via a simple quoted
+   filename value now works by default without any extra quoting:
+
+   ```shell
+       rsync -aiv host:'a simple file.pdf' .
+   ```
+
+   Wildcards are not escaped in filename args, but they are escaped in options
+   like the [`--suffix`](rsync.1#opt) and [`--usermap`](rsync.1#opt) values.
+   If your rsync script depends on the old arg-splitting behavior, either run
+   it with the [`--old-args`](rsync.1#opt) option or `export RSYNC_OLD_ARGS=1`
+   in the script's environment.  See also the [ADVANCED USAGE](rsync.1#)
+   section of rsync's manpage for how to use a more modern arg style.
+
+ - A long-standing bug was preventing rsync from figuring out the current
+   locale's decimal point character, which made rsync always output numbers
+   using the "C" locale.  Since this is now fixed in 3.2.4, a script that
+   parses rsync's decimal numbers (e.g. from the verbose footer) may want to
+   setup the environment in a way that the output continues to be in the C
+   locale.  For instance, one of the following should work fine:
+
+   ```shell
+       export LC_ALL=C.UTF-8
+   ```
+
+   or if iconv translations are needed:
+
+   ```shell
+       if [ "${LC_ALL:-}" ]; then
+           export LANG="$LC_ALL"
+           export LC_CTYPE="$LC_ALL"
+           unset LC_ALL
+       fi
+       export LC_NUMERIC=C.UTF-8
+   ```
+
+### SECURITY FIXES:
+
+ - A fix for CVE-2018-25032 in the bundled zlib (memory corruption issue).
+
+### BUG FIXES:
+
+ - Fixed a bug with [`--inplace`](rsync.1#opt) + [`--sparse`](rsync.1#opt) (and
+   a lack of [`--whole-file`](rsync.1#opt)) where the destination file could
+   get reconstructed with bogus data.  Since the bug can also be avoided by
+   using (the seemingly redundant) [`--no-W`](rsync.1#opt) on the receiving
+   side, the latest rsync will now send `--no-W` to a remote receiver when this
+   option combination occurs.  If your client rsync is not new enough to do
+   this for you (or if you're just paranoid), you can manually specify `--no-W
+   -M--no-W` (when not using [`--whole-file`](rsync.1#opt)) to make sure the
+   bug is avoided.
+
+ - Fixed a bug with [`--mkpath`](rsync.1#opt) if a single-file copy specifies
+   an existing destination dir with a non-existing destination filename.
+
+ - Fixed `--update -vv` to output "is uptodate" instead of "is newer" messages
+   for files that are being skipped due to an identical modify time.  (This was
+   a new output quirk in 3.2.3.)
+
+ - When doing an append transfer, the sending side's file must not get shorter
+   or it is skipped. Fixes a crash that could occur when the size changes to 0
+   in the middle of the send negotiations.
+
+ - When dealing with special files (see [`--specials`](rsync.1#opt)) in an
+   alt-dest hierarchy, rsync now checks the non-permission mode bits to ensure
+   that the 2 special files are really the same before hard-linking them
+   together.
+
+ - Fixed a bug where [`--delay-updates`](rsync.1#opt) with stale partial data
+   could cause a file to fail to update.
+
+ - Fixed a few places that would output an INFO message with
+   [`--info=NAME`](rsync.1#opt) that should only have been output given
+   [`--verbose`](rsync.1#opt) or [`--itemize-changes`](rsync.1#opt).
+
+ - Avoid a weird failure if you run a local copy with a (useless)
+   [`--rsh`](rsync.1#opt) option that contains a `V` in the command.
+
+ - Fixed a long-standing compression bug where the compression level of the
+   first file transferred affected the level for all future files.  Also, the
+   per-file compression skipping has apparently never worked, so it is now
+   documented as being ineffective.
+
+ - Fixed a truncate error when a `--write-devices` copy wrote a file onto a
+   device that was shorter than the device.
+
+ - Made `--write-devices` support both `--checksum` and `--no-whole-file` when
+   copying to a device.
+
+ - Improved how the [`--stop-at`](rsync.1#opt), [`--stop-after`](rsync.1#opt),
+   and (the deprecated) [`--time-limit`](rsync.1#opt) options check to see if
+   the allowed time is over, which should make rsync exit more consistently.
+
+ - Tweak --progress to display "`??:??:??`" when the time-remaining value is so
+   large as to be meaningless.
+
+ - Silence some chmod warnings about symlinks when it looks like we have a
+   function to set their permissions but they can't really be set.
+
+ - Fixed a potential issue in git-set-file-times when handling commits with
+   high-bit characters in the description & when handling a description that
+   might mimic the git raw-commit deliniators.  (See the support dir.)
+
+ - The bundled systemd/rsync.service file now includes `Restart=on-failure`.
+
+### ENHANCEMENTS:
+
+ - Use openssl's `-verify_hostname` option in the rsync-ssl script.
+
+ - Added extra info to the "FILENAME exists" output of
+   [`--ignore-existing`](rsync.1#opt) when [`--info=skip2`](rsync.1#opt) is
+   used.  The skip message becomes "FILENAME exists (INFO)" where the INFO is
+   one of "type change", "sum change" (requires [`--checksum`](rsync.1#opt)),
+   "file change" (based on the quick check), "attr change", or "uptodate".
+   Prior versions only supported `--info=skip1`.
+
+ - Added the [`--fsync`](rsync.1#opt) option (promoted from the patches repo).
+
+ - Added the [`--copy-devices`](rsync.1#opt) option.  Compared to the
+   historical version from the rsync-patches repo, this version: properly
+   handles `--checksum`; fixes a truncation bug when doing an `--inplace` copy
+   onto a longer file; fixes several bugs in the `--itemize` output; and only
+   the sending side needs the enhanced rsync for the copy to work.
+
+ - Reduced memory usage for an incremental transfer that has a bunch of small
+   directories.
+
+ - The rsync daemon can now handle a client address with an implied "%scope"
+   suffix.
+
+ - Added support for [`--atimes`](rsync.1#opt) on macOS and fixed a bug where
+   it wouldn't work without [`--times`](rsync.1#opt).
+
+ - Rsync can now update the xattrs on a read-only file when your user can
+   temporarily add user-write permission to the file. (It always worked for a
+   root transfer.)
+
+ - Rsync can now work around an [`--inplace`](rsync.1#opt) update of a file
+   that is being refused due to the Linux fs.protected_regular sysctl setting.
+
+ - When [`--chown`](rsync.1#opt), [`--usermap`](rsync.1#opt), or
+   [`--groupmap`](rsync.1#opt) is specified, rsync now makes sure that the
+   appropriate [`--owner`](rsync.1#opt) and/or [`--group`](rsync.1#opt) options
+   are enabled.
+
+ - Added the [`--info=NONREG`](rsync.1#opt) setting to control if rsync should
+   warn about non-regular files in the transfer.  This is enabled by default
+   (keeping the behavior the same as before), so specifying `--info=nonreg0`
+   can be used to turn the warnings off.
+
+ - An optional asm optimization for the rolling checksum from Shark64. Enable
+   it with `./configure --enable-roll-asm`.
+
+ - Using `--debug=FILTER` now outputs a caution message if a filter rule
+   has trailing whitespace.
+
+ - Transformed rrsync into a python script with improvements:
+   - Security has been beefed up.
+   - The known rsync options were updated to include recent additions.
+   - Make rrsync reject [`--copy-links`](rsync.1#opt) (`-L`),
+     [`--copy-dirlinks`](rsync.1#opt) (`-k`), &
+     [`--keep-dirlinks`](rsync.1#opt) (`-K`) by default to make it harder to
+     exploit any out-of-subdir symlinks.
+   - A new rrsync option of [`-munge`](rrsync.1#opt) tells rrsync to always
+     enable rsync's [`--munge-links`](rsync.1#opt) option on the server side.
+   - A new rrsync option of [`-no-lock`](rrsync.1#opt) disables a new
+     single-use locking idiom that is the default when [`-ro`](rrsync.1#opt) is
+     not used (useful with [`-munge`](rrsync.1#opt)).
+   - A new rrsync option of [`-no-del`](rrsync.1#opt) disables all `--remove*`
+     and `--delete*` rsync options on the server side.
+   - The log format has been tweaked slightly to add seconds to the timestamp
+     and to output the command executed as a tuple (making the args clearer).
+   - An rrsync.1 manpage was added (in the support dir with rrsync).
+
+ - Added options to the lsh script to facilitate rrsync testing. (See the
+   support dir.)
+
+ - Transformed the atomic-rsync script into a python script and added the
+   ability to ignore one or more non-zero exit codes.  By default, it now
+   ignores code 24, the file-vanished exit code. (See the support dir.)
+
+ - Transformed the munge-symlinks script into python. (See the support dir.)
+
+ - Improved the rsync-no-vanished script to not join stdout & stderr together.
+   (See the support dir.)
+
+ - Work around a glibc bug where lchmod() breaks in a chroot w/o /proc mounted.
+
+ - Try to support a client that sent a remote rsync a wacko stderr file handle
+   (such as an older File::RsyncP perl library used by BackupPC).
+
+ - Lots of manpage improvements, including better HTML versions.
+
+### PACKAGING RELATED:
+
+ - Give configure the `--with-rrsync` option if you want `make install` to
+   install the (now python3) rrsync script and its new manpage.
+
+ - If the rrsync script is installed, its package should be changed to depend
+   on python3 and the (suggested but not mandatory) python3 braceexpand lib.
+
+ - When creating a package from a non-release version (w/o a git checkout), the
+   packager can elect to create git-version.h and define RSYNC_GITVER to the
+   string they want `--version` to output.  (The file is still auto-generated
+   using the output of `git describe` when building inside a non-shallow git
+   checkout, though.)
+
+ - Renamed configure's `--enable-simd` option to `--enable-roll-simd` and added
+   the option `--enable-roll-asm` to use the new asm version of the code.  Both
+   are x86_64/amd64 only.
+
+ - Renamed configure's `--enable-asm` option to `--enable-md5-asm` to avoid
+   confusion with the asm option for the rolling checksum.  It is also honored
+   even when openssl crypto is in use.  This allows: normal MD4 & MD5, normal
+   MD4 + asm MD5, openssl MD4 & MD5, or openssl MD4 + asm MD5 depending on the
+   configure options selected.
+
+ - Made SIMD & asm configure checks default to "no" on non-Linux hosts due to
+   various reports of problems on NetBSD & macOS hosts.  These were also
+   tweaked to allow enabling the feature on a host_cpu of amd64 (was only
+   allowed on x86_64 before).
+
+ - Fixed configure to not fail at the SIMD check when cross-compiling.
+
+ - Improved the IPv6 determination in configure.
+
+ - Compile the C files with `-pedantic-errors` (when possible) so that we will
+   get warned if a static initialization overflows in the future (among other
+   things).
+
+ - When linking with an external zlib, rsync renames its `read_buf()` function
+   to `read_buf_()` to avoid a symbol clash on an unpatched zlib.
+
+ - Added a SECURITY.md file.
+
+### DEVELOPER RELATED:
+
+ - Made it easier to write rsync tests that diff the output while also checking
+   the status code, and used the idiom to improve the existing tests. (See the
+   `checkdiff` and `checkdiff2` idioms in the `testsuite/*.test` files.
+
+ - The packaging scripts & related python lib got some minor enhancements.
+
+### INTERNAL
+
+ - Use setenv() instead of putenv() when it is available.
+
+ - Improve the logic in compat.c so that we don't need to try to remember to
+   sprinkle `!local_server` exceptions throughout the protocol logic.
+
+ - One more C99 Flexible Array improvement (started in the last release) and
+   make use of the C99 `%zd` format string when printing size_t values (when
+   possible).
+
+ - Use mallinfo2() instead of mallinfo(), when available.
+

+
+# NEWS for rsync 3.2.3 (6 Aug 2020)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Fixed a bug in the xattr code that was freeing the wrong object when trying
+   to cleanup the xattr list.
+
+ - Fixed a bug in the xattr code that was not leaving room for the "rsync."
+   prefix in some instances where it needed to be added.
+
+ - Restored the ability to use [`--bwlimit=0`](rsync.1#opt) to specify no
+   bandwidth limit.  (It was accidentally broken in 3.2.2.)
+
+ - Fixed a bug when combining [`--delete-missing-args`](rsync.1#opt) with
+   [`--no-implied-dirs`](rsync.1#opt) & [`-R`](rsync.1#opt) where rsync might
+   create the destination path of a missing arg.  The code also avoids some
+   superfluous warnings for nested paths of removed args.
+
+ - Fixed an issue where hard-linked devices could cause the rdev_major value to
+   get out of sync between the sender and the receiver, which could cause a
+   device to get created with the wrong major value in its major,minor pair.
+
+ - Rsync now complains about a missing [`--temp-dir`](rsync.1#opt) before
+   starting any file transfers.
+
+ - A completely empty source arg is now a fatal error.  This doesn't change
+   the handling of implied dot-dir args such as "localhost:" and such.
+
+### ENHANCEMENTS:
+
+ - Allow [`--max-alloc=0`](rsync.1#opt) to specify no limit to the alloc sanity
+   check.
+
+ - Allow [`--block-size=SIZE`](rsync.1#opt) to specify the size using units
+   (e.g. "100K").
+
+ - The name of the id-0 user & group are now sent to the receiver along with
+   the other user/group names in the transfer (instead of assuming that both
+   sides have the same id-0 names).
+
+ - Added the [`--stop-after`](rsync.1#opt) and [`--stop-at`](rsync.1#opt)
+   options (with a [`--time-limit`](rsync.1#opt) alias for `--stop-after`).
+   This is an enhanced version of the time-limit patch from the patches repo.
+
+ - Added the [`name converter`](rsyncd.conf.5#opt) daemon parameter to make it
+   easier to convert user & group names inside a chrooted daemon module.  This
+   is based on the nameconverter patch with some improvements, including a
+   tweak to the request protocol (so if you used this patch in the past, be
+   sure to update your converter script to use newlines instead of null chars).
+
+ - Added [`--crtimes`](rsync.1#opt) (`-N`) option for preserving the file's
+   create time (I believe that this is macOS only at the moment).
+
+ - Added [`--mkpath`](rsync.1#opt) option to tell rsync that it should create a
+   non-existing path component of the destination arg.
+
+ - Added [`--stderr=errors|all|client`](rsync.1#opt) to replace the
+   `--msgs2stderr` and `--no-msgs2stderr` options (which are still accepted).
+   The default use of stderr was changed to be `--stderr=errors` where all the
+   processes that have stderr available output directly to stderr, which should
+   help error messages get to the user more quickly, especially when doing a
+   push (which includes local copying).  This also allows rsync to exit quickly
+   when a receiver failure occurs, since rsync doesn't need to try to keep the
+   connection alive long enough for the fatal error to go from the receiver to
+   the generator to the sender.  The old default can be requested via
+   `--stderr=client`.  Also changed is that a non-default stderr mode is
+   conveyed to the remote rsync (using the older option names) instead of
+   requiring the user to use [`--remote-option`](rsync.1#opt) (`-M`) to tell
+   the remote rsync what to do.
+
+ - Added the ability to specify "@netgroup" names to the [`hosts
+   allow`](rsyncd.conf.5#opt) and [`hosts deny`](rsyncd.conf.5#opt) daemon
+   parameters.  This is a finalized version of the netgroup-auth patch from the
+   patches repo.
+
+ - Rsync can now hard-link symlinks on FreeBSD due to it making use of the
+   linkat() function when it is available.
+
+ - Output file+line info on out-of-memory & overflow errors while also avoiding
+   the output of alternate build-dir path info that is not useful to the user.
+
+ - Change configure to know that Cygwin supports Linux xattrs.
+
+ - Improved the testsuite on FreeBSD & Cygwin.
+
+ - Added some compatibility code for HPE NonStop platforms.
+
+ - Improved the INSTALL.md info.
+
+ - Added a few more suffixes to the default skip-compress list.
+
+ - Improved configure's error handling to notify about several issues at once
+   instead of one by one (for the newest optional features).
+
+### INTERNAL:
+
+ - Use a simpler overflow check idiom in a few spots.
+
+ - Use a C99 Flexible Array for a trailing variable-size filename in a struct
+   (with a fallback to the old 1-char string kluge for older compilers).
+

+
+# NEWS for rsync 3.2.2 (4 Jul 2020)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Avoid a crash when a daemon module enables `transfer logging` without
+   setting a `log format` value.
+
+ - Fixed installing rsync-ssl script from an alternate build dir.
+
+ - Fixed the updating of configure.sh from an alternate build dir.
+
+ - Apple requires the asm function name to begin with an underscore.
+
+ - Avoid a test failure in the daemon test when `--atimes` is disabled.
+
+### ENHANCEMENTS:
+
+ - Allow the server side to restrict checksum & compression choices via the
+   same environment variables the client uses.  The env vars can be divided
+   into "client list & server list" by the "`&`" char or the same list can
+   apply to both.
+
+ - Simplify how the negotiation environment variables apply when interacting
+   with an older rsync and also when a list contains only invalid names.
+
+ - Do not allow a negotiated checksum or compression choice of "none" unless
+   the user authorized it via an environment variable or command-line option.
+
+ - Added the `--max-alloc=SIZE` option to be able to override the memory
+   allocator's sanity-check limit.  It defaults to 1G (as before) but the error
+   message when exceeding it specifically mentions the new option so that you
+   can differentiate an out-of-memory error from a failure of this limit.  It
+   also allows you to specify the value via the RSYNC_MAX_ALLOC environment
+   variable.
+
+ - Add the "open atime" daemon parameter to allow a daemon to always enable or
+   disable the use of O_NOATIME (the default is to let the user control it).
+
+ - The default systemd config was changed to remove the `ProtectHome=on`
+   setting since rsync is often used to serve files in /home and /root and this
+   seemed a bit too strict.  Feel free to use `systemctl edit rsync` to add
+   that restriction (or maybe `ProtectHome=read-only`), if you like.  See the
+   3.2.0 NEWS for the other restrictions that were added compared to 3.1.3.
+
+ - The memory allocation functions now automatically check for a failure and
+   die when out of memory.  This eliminated some caller-side check-and-die
+   code and added some missing sanity-checking of allocations.
+
+ - Put optimizations into their own list in the `--version` output.
+
+ - Improved the manpage a bit more.
+
+### PACKAGING RELATED:
+
+ - Prepared the checksum code for an upcoming xxHash release that provides new
+   XXH3 (64-bit) & XXH128 (128-bit) checksum routines.  These will not be
+   compiled into rsync until the xxhash v0.8.0 include files are installed on
+   the build host, and that release is a few weeks away at the time this was
+   written.  So, if it's now the future and you have packaged and installed
+   xxhash-0.8.0-devel, a fresh rebuild of rsync 3.2.2 will give you the new
+   checksum routines.  Just make sure that the new rsync package depends on
+   xxhash >= 0.8.0.
+
+### DEVELOPER RELATED:
+
+ - Moved the version number out of configure.ac into its own version.h file so
+   that we don't need to reconfigure just because the version number changes.
+
+ - Moved the daemon parameter list into daemon-parm.txt so that an awk script
+   can create the interrelated structs and accessors that loadparm.c needs.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.2.1 (22 Jun 2020)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Fixed a potential build issue with the MD5 assembly-language code by
+   removing some non-portable directives.
+
+ - Use the preprocessor with the asm file to ensure that if the code is
+   unneeded, it doesn't get built.
+
+ - Avoid the stack getting set to executable when including the asm code.
+
+ - Some improvements in the SIMD configure testing to try to avoid build
+   issues, such as avoiding a clang++ core dump when `-g` is combined with
+   `-O2`.  Note that clang++ is quite buggy in this area, and it does still
+   crash for some folks, so just use `--disable-simd` if you need to avoid
+   their buggy compiler (since the configure test is apparently not finding
+   all the compilers that will to crash and burn).
+
+ - Fixed an issue in the md2man script when building from an alternate dir.
+
+ - Disable `--atimes` on macOS (it apparently just ignores the atime change).
+
+### ENHANCEMENTS:
+
+ - The use of `--backup-dir=STR` now implies `--backup`.
+
+ - Added `--zl=NUM` as a short-hand for `--compress-level=NUM`.
+
+ - Added `--early-input=FILE` option that allows the client to send some
+   data to a daemon's (optional) "early exec" script on its stdin.
+
+ - Mention atimes in the capabilities list that `--version` outputs.
+
+ - Mention either "default protect-args" or "optional protect-args" in the
+   `--version` capabilities depending on how rsync was configured.
+
+ - Some info on optimizations is now elided from the `--version` capabilities
+   since they aren't really user-facing capabilities.  You can still see the
+   info (plus the status of a couple extra optimizations) by repeating the
+   `--version` option (e.g. `-VV`).
+
+ - Updated various URLs to be https instead of http.
+
+ - Some documentation improvements.
+
+### PACKAGING RELATED:
+
+ - If you had to use `--disable-simd` for 3.2.0, you might want to try removing
+   that and see if it will succeed or auto-disable.  Some buggy clang++
+   compilers are still not auto disabled, though.
+
+ - The MD5 asm code is now under its own configure flag (not shared with the
+   SIMD setting), so if you have any issues compiling it, re-run configure with
+   `--disable-asm`.
+
+ - Merged the OLDNEWS.md file into NEWS.md.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.2.0 (19 Jun 2020)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Avoid a potential out-of-bounds read in daemon mode if argc can be made to
+   become 0.
+
+ - Fix the default list of skip-compress files for non-daemon transfers.
+
+ - Fix xattr filter rules losing an 'x' attribute in a non-local transfer.
+
+ - Avoid an error when a check for a potential fuzzy file happens to reference
+   a directory.
+
+ - Make the atomic-rsync helper script have a more consistent error-exit.
+
+ - Make sure that a signal handler's use of exit_cleanup() calls `_exit()`
+   instead of exit().
+
+ - Various zlib fixes, including security fixes for CVE-2016-9843,
+   CVE-2016-9842, CVE-2016-9841, and CVE-2016-9840.
+
+ - Fixed an issue with `--remove-source-files` not removing a source symlink
+   when combined with `--copy-links`.
+
+ - Fixed a bug where the daemon would fail to write early fatal error messages
+   to the client, such as refused or unknown command-line options.
+
+ - Fixed the block-size validation logic when dealing with older protocols.
+
+ - Some rrsync fixes and enhancements to handle the latest options.
+
+ - Fixed a problem with the `--link-dest`|`--copy-dest` code when `--xattrs`
+   was specified along with multiple alternate-destination directories (it
+   could possibly choose a bad file match while trying to find a better xattr
+   match).
+
+ - Fixed a couple bugs in the handling of files with the `--sparse` option.
+
+ - Fixed a bug in the writing of the batch.sh file (w/`--write-batch`) when the
+   source & destination args were not last on the command-line.
+
+ - Avoid a hang when an overabundance of messages clogs up all the I/O buffers.
+
+ - Fixed a mismatch in the RSYNC_PID values put into the environment of
+   `pre-xfer exec` and a `post-xfer exec`.
+
+ - Fixed a crash in the `--iconv` code.
+
+ - Fixed a rare crash in the popt_unalias() code.
+
+### ENHANCEMENTS:
+
+ - The default systemd config was made stricter by default.  For instance,
+   `ProtectHome=on` (which hides content in /root and /home/USER dirs),
+   `ProtectSystem=full` (which makes /usr, /boot, & /etc dirs read-only), and
+   `PrivateDevices=on` (which hides devices).  You can override any of these
+   using the standard `systemctl edit rsync` and add one or more directives
+   under a `[Service]` heading (and restart the rsync service).
+
+ - Various checksum enhancements, including the optional use of openssl's MD4 &
+   MD5 checksum algorithms, some x86-64 optimizations for the rolling checksum,
+   some x86-64 optimizations for the (non-openssl) MD5 checksum, the addition
+   of xxHash checksum support, and a negotiation heuristic that ensures that it
+   is easier to add new checksum algorithms in the future.  The environment
+   variable `RSYNC_CHECKSUM_LIST` can be used to customize the preference order
+   of the negotiation, or use `--checksum-choice` (`--cc`) to force a choice.
+
+ - Various compression enhancements, including the addition of zstd and lz4
+   compression algorithms and a negotiation heuristic that picks the best
+   compression option supported by both sides.  The environment variable
+   `RSYNC_COMPRESS_LIST` can be used to customize the preference order of the
+   negotiation, or use `--compress-choice` (`--zc`) to force a choice.
+
+ - Added a `--debug=NSTR` option that outputs details of the new negotiation
+   strings (for checksums and compression).  The first level just outputs the
+   result of each negotiation on the client, level 2 outputs the values of the
+   strings that were sent to and received from the server, and level 3 outputs
+   all those values on the server side too (when the server was given the debug
+   option).
+
+ - The `--debug=OPTS` command-line option is no longer auto-forwarded to the
+   remote rsync which allows for the client and server to have different levels
+   of debug specified. This also allows for newer debug options to be
+   specified, such as using `--debug=NSTR` to see the negotiated hash result,
+   without having the command fail if the server version is too old to handle
+   that debug item. Use `-M--debug=OPTS` to send the options to the remote side.
+
+ - Added the `--atimes` option based on the long-standing patch (just with some
+   fixes that the patch has been needing).
+
+ - Added `--open-noatime` option to open files using `O_NOATIME`.
+
+ - Added the `--write-devices` option based on the long-standing patch.
+
+ - Added openssl & preliminary gnutls support to the rsync-ssl script, which is
+   now installed by default.  This was unified with the old stunnel-rsync
+   helper script to simplify packaging.  Note that the script accepts the use
+   of `--type=gnutls` for gnutls testing, but does not look for gnutls-cli on
+   the path yet.  The use of `--type=gnutls` will not work right until
+   gnutls-cli no longer drops data.
+
+ - Rsync was enhanced to set the `RSYNC_PORT` environment variable when running
+   a daemon-over-rsh script. Its value is the user-specified port number (set
+   via `--port` or an rsync:// URL) or 0 if the user didn't override the port.
+
+ - Added the `proxy protocol` daemon parameter that allows your rsyncd to know
+   the real remote IP when it is setup behind a proxy.
+
+ - Added negated matching to the daemon's `refuse options` setting by using
+   match strings that start with a `!` (such as `!compress*`).  This lets you
+   refuse all options except for a particular approved list, for example.  It
+   also lets rsync refuse certain options by default (such as `write-devices`)
+   while allowing the config to override that, as desired.
+
+ - Added the `early exec` daemon parameter that runs a script before the
+   transfer parameters are known, allowing some early setup based on module
+   name.
+
+ - Added status output in response to a signal (via both SIGINFO & SIGVTALRM).
+
+ - Added `--copy-as=USER` option to give some extra security to root-run rsync
+   commands into/from untrusted directories (such as backups and restores).
+
+ - When resuming the transfer of a file in the `--partial-dir`, rsync will now
+   update that partial file in-place instead of creating yet another tmp file
+   copy.  This requires both sender & receiver to be at least v3.2.0.
+
+ - Added support for `RSYNC_SHELL` & `RSYNC_NO_XFER_EXEC` environment variables
+   that affect the early, pre-xfer, and post-xfer exec rsync daemon parameters.
+
+ - Optimize the `--fuzzy --fuzzy` heuristic to avoid the fuzzy directory scan
+   until all other basis-file options are exhausted (such as `--link-dest`).
+
+ - Have the daemon log include the normal-exit sent/received stats when the
+   transfer exited with an error when possible (i.e. if it is the sender).
+
+ - The daemon now locks its pid file (when configured to use one) so that it
+   will not fail to start when the file exists but no daemon is running.
+
+ - Various manpage improvements, including some html representations (that
+   aren't installed by default).
+
+ - Made `-V` the short option for `--version` and improved its information.
+
+ - Pass the `-4` or `-6` option to the ssh command, making it easier to type
+   than `--rsh='ssh -4'` (or the `-6` equivalent).
+
+ - Added example config for rsyncd SSL proxy configs to rsyncd.conf.
+
+ - More errors messages now mention if the error is coming from the sender or
+   the receiver.
+
+### PACKAGING RELATED:
+
+ - Add installed bash script: /usr/bin/rsync-ssl
+
+ - Add installed manpage: /usr/man/man1/rsync-ssl.1
+
+ - Tweak auxiliary doc file names, such as: README.md, INSTALL.md, & NEWS.md.
+
+ - The rsync-ssl script wants to run openssl or stunnel4, so consider adding a
+   dependency for one of those options (though it's probably fine to just let
+   it complain about being unable to find the program and let the user decide
+   if they want to install one or the other).
+
+ - If you packaged rsync + rsync-ssl + rsync-ssl-daemon as separate packages,
+   the rsync-ssl package is now gone (rsync-ssl should be considered to be
+   mainstream now that Samba requires SSL for its rsync daemon).
+
+ - Add _build_ dependency for liblz4-dev, libxxhash-dev, libzstd-dev, and
+   libssl-dev.  These development libraries will give rsync extra compression
+   algorithms, extra checksum algorithms, and allow use of openssl's crypto
+   lib for (potentially) faster MD4/MD5 checksums.
+
+ - Add _build_ dependency for g++ or clang++ on x86_64 systems to enable the
+   SIMD checksum optimizations.
+
+ - Add _build_ dependency for _either_ python3-cmarkcfm or python3-commonmark
+   to allow for patching of manpages or building a git release.  This is not
+   required for a release-tar build, since it comes with pre-built manpages.
+   Note that cmarkcfm is faster than commonmark, but they generate the same
+   data.  The commonmark dependency is easiest to install since it's native
+   python, and can even be installed via `pip3 install --user commonmark` if
+   you want to just install it for the build user.
+
+ - Remove yodl _build_ dependency (if it was even listed before).
+
+### DEVELOPER RELATED:
+
+ - Silenced some annoying warnings about major() & minor() by improving an
+   autoconf include-file check.
+
+ - Converted the manpages from yodl to markdown. They are now processed via a
+   simple python3 script using the cmarkgfm **or** commonmark library.  This
+   should make it easier to package rsync, since yodl is rather obscure.
+
+ - Improved some configure checks to work better with strict C99 compilers.
+
+ - Some perl building/packaging scripts were recoded into awk and python3.
+
+ - Some defines in byteorder.h were changed into static inline functions that
+   will help to ensure that the args don't get evaluated multiple times on
+   "careful alignment" hosts.
+
+ - Some code typos were fixed (as pointed out by a Fossies run).
+

+
+# NEWS for rsync 3.1.3 (28 Jan 2018)
+
+## Changes in this version:
+
+### SECURITY FIXES:
+
+ - Fixed a buffer overrun in the protocol's handling of xattr names and ensure
+   that the received name is null terminated.
+
+ - Fix an issue with `--protect-args` where the user could specify the arg in the
+   protected-arg list and short-circuit some of the arg-sanitizing code.
+
+### BUG FIXES:
+
+ - Don't output about a new backup dir without appropriate info verbosity.
+
+ - Fixed some issues with the sort functions in the rsyncstats script (in the
+   support dir).
+
+ - Added a way to specify daemon config lists (e.g. users, groups, etc) that
+   contain spaces (see `auth users` in the latest rsyncd.conf manpage).
+
+ - If a backup fails (e.g. full disk) rsync exits with an error.
+
+ - Fixed a problem with a doubled `--fuzzy` option combined with `--link-dest`.
+
+ - Avoid invalid output in the summary if either the start or end time had an
+   error.
+
+ - We don't allow a popt alias to affect the `--daemon` or `--server` options.
+
+ - Fix daemon exclude code to disallow attribute changes in addition to
+   disallowing transfers.
+
+ - Don't force nanoseconds to match if a non-transferred, non-checksummed file
+   only passed the quick-check w/o comparing nanoseconds.
+
+### ENHANCEMENTS:
+
+ - Added the ability for rsync to compare nanosecond times in its file-check
+   comparisons, and added support nanosecond times on Mac OS X.
+
+ - Added a short-option (`-@`) for `--modify-window`.
+
+ - Added the `--checksum-choice=NAME[,NAME]` option to choose the checksum
+   algorithms.
+
+ - Added hashing of xattr names (with using `-X`) to improve the handling of
+   files with large numbers of xattrs.
+
+ - Added a way to filter xattr names using include/exclude/filter rules (see
+   the `--xattrs` option in the manpage for details).
+
+ - Added `daemon chroot|uid|gid` to the daemon config (in addition to the old
+   chroot|uid|gid settings that affect the daemon's transfer process).
+
+ - Added `syslog tag` to the daemon configuration.
+
+ - Some manpage improvements.
+
+### DEVELOPER RELATED:
+
+ - Tweak the `make` output when yodl isn't around to create the manpages.
+
+ - Changed an obsolete autoconf compile macro.
+
+ - Support newer yodl versions when converting manpages.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.1.2 (21 Dec 2015)
+
+## Changes in this version:
+
+### SECURITY FIXES:
+
+ - Make sure that all transferred files use only path names from inside the
+   transfer. This makes it impossible for a malicious sender to try to make the
+   receiver use an unsafe destination path for a transferred file, such as a
+   just-sent symlink.
+
+### BUG FIXES:
+
+ - Change the checksum seed order in the per-block checksums. This prevents
+   someone from trying to create checksum blocks that match in sum but not
+   content.
+
+ - Fixed a with the per-dir filter files (using `-FF`) that could trigger an
+   assert failure.
+
+ - Only skip `set_modtime()` on a transferred file if the time is exactly
+   right.
+
+ - Don't create an empty backup dir for a transferred file that doesn't exist
+   yet.
+
+ - Fixed a bug where `--link-dest` and `--xattrs` could cause rsync to exit if
+   a filename had a matching dir of the same name in the alt-dest area.
+
+ - Allow more than 32 group IDs per user in the daemon's gid=LIST config.
+
+ - Fix the logging of %b & %c via `--log-file` (daemon logging was already
+   correct, as was `--out-format='%b/%c'`).
+
+ - Fix erroneous acceptance of `--info=5` & `--debug=5` (an empty flag name is
+   not valid).
+
+### ENHANCEMENTS:
+
+ - Added `(DRY RUN)` info to the `--debug=exit` output line.
+
+ - Use usleep() for our msleep() function if it is available.
+
+ - Added a few extra long-option names to rrsync script, which will make
+   BackupPC happier.
+
+ - Made configure choose to use Linux xattrs on NetBSD (rather than not
+   supporting xattrs).
+
+ - Added `-wo` (write-only) option to rrsync support script.
+
+ - Misc. manpage tweaks.
+
+### DEVELOPER RELATED:
+
+ - Fixed a bug with the Makefile's use of `INSTALL_STRIP`.
+
+ - Improve a test in the suite that could get an erroneous timestamp error.
+
+ - Tweaks for newer versions of git in the packaging tools.
+
+ - Improved the m4 generation rules and some autoconf idioms.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.1.1 (22 Jun 2014)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - If the receiver gets bogus filenames from the sender (an unexpected leading
+   slash or a `..` infix dir), exit with an error. This prevents a malicious
+   sender from trying to inject filenames that would affect an area outside the
+   destination directories.
+
+ - Fixed a failure to remove the partial-transfer temp file when interrupted
+   (and rsync is not saving the partial files).
+
+ - Changed the chown/group/xattr-set order to avoid losing some security-
+   related xattr info (that would get cleared by a chown).
+
+ - Fixed a bug in the xattr-finding code that could make a non-root-run
+   receiver not able to find some xattr numbers.
+
+ - Fixed a bug in the early daemon protocol where a timeout failed to be
+   honored (e.g. if the remote side fails to send us the initial protocol
+   greeting).
+
+ - Fixed unintended inclusion of commas in file numbers in the daemon log.
+
+ - We once again send the 'f' sub-flag (of `-e`) to the server side so it knows
+   that we can handle incremental-recursion directory errors properly in older
+   protocols.
+
+ - Fixed an issue with too-aggressive keep-alive messages causing a problem for
+   older rsync versions early in the transfer.
+
+ - Fixed an incorrect message about backup-directory-creation when using
+   `--dry-run` and the backup dir is not an absolute path.
+
+ - Fixed a bug where a failed deletion and/or a failed sender-side removal
+   would not affect the exit code.
+
+ - Fixed a bug that caused a failure when combining `--delete-missing-args`
+   with `--xattrs` and/or `--acls`.
+
+ - Fixed a strange `dir_depth` assertion error that was caused by empty-dir
+   removals and/or duplicate files in the transfer.
+
+ - Fixed a problem with `--info=progress2`'s output stats where rsync would
+   only update the stats at the end of each file's transfer. It now uses the
+   data that is flowing for the current file, making the stats more accurate
+   and less jumpy.
+
+ - Fixed an itemize bug that affected the combo of `--link-dest`, `-X`, and
+   `-n`.
+
+ - Fixed a problem with delete messages not appearing in the log file when the
+   user didn't use `--verbose`.
+
+ - Improve chunked xattr reading for OS X.
+
+ - Removed an attempted hard-link xattr optimization that was causing a
+   transfer failure. This removal is flagged in the compatibility code, so if a
+   better fix can be discovered, we have a way to flip it on again.
+
+ - Fixed a bug when the receiver is not configured to be able to hard link
+   symlimks/devices/special-file items but the sender sent some of these items
+   flagged as hard-linked.
+
+ - We now generate a better error if the buffer overflows in `do_mknod()`.
+
+ - Fixed a problem reading more than 16 ACLs on some OSes.
+
+ - Fixed the reading of the secrets file to avoid an infinite wait when the
+   username is missing.
+
+ - Fixed a parsing problem in the `--usermap`/`--groupmap` options when using
+   MIN-MAX numbers.
+
+ - Switched Cygwin back to using socketpair `pipes` to try to speed it up.
+
+ - Added knowledge of a few new options to rrsync.
+
+### ENHANCEMENTS:
+
+ - Tweaked the temp-file naming when `--temp-dir=DIR` is used: the temp-file
+   names will not get a '.' prepended.
+
+ - Added support for a new-compression idiom that does not compress all the
+   matching data in a transfer. This can help rsync to use less cpu when a
+   transfer has a lot of matching data, and also makes rsync compatible with a
+   non-bundled zlib. See the `--new-compress` and `--old-compress` options in
+   the manpage.
+
+ - Added the rsync-no-vanished shell script. (See the support dir.)
+
+ - Made configure more prominently mention when we failed to find yodl (in case
+   the user wants to be able to generate manpages from `*.yo` files).
+
+ - Have manpage mention how a daemon's max-verbosity setting affects info and
+   debug options. Also added more clarification on backslash removals for
+   excludes that contain wildcards.
+
+ - Have configure check if for the attr lib (for getxattr) for those systems
+   that need to link against it explicitly.
+
+ - Change the early dir-creation logic to only use that idiom in an
+   inc-recursive copy that is preserving directory times. e.g. using
+   `--omit-dir-times` will avoid these early directories being created.
+
+ - Fix a bug in `cmp_time()` that would return a wrong result if the 2 times
+   differed by an amount greater than what a `time_t` can hold.
+
+### DEVELOPER RELATED:
+
+ - We now include an example systemd file (in packaging/systemd).
+
+ - Tweaked configure to make sure that any intended use of the included popt
+   and/or zlib code is put early in the CFLAGS.

+
+# NEWS for rsync 3.1.0 (28 Sep 2013)
+
+## Changes in this version:
+
+### PROTOCOL NUMBER:
+
+ - The protocol number was changed to 31.
+
+### OUTPUT CHANGES:
+
+ - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the
+   `--human-readable` option for a way to turn it off. See also the daemon's
+   `log format` parameter and related command-line options (including
+   `--out-format`) for a modifier that can be used to request digit-grouping or
+   human-readable output in log escapes. (Note that log output is unchanged by
+   default.)
+
+ - The `--list-only` option is now affected by the `--human-readable` setting.
+   It will display digit groupings by default, and unit suffixes if higher
+   levels of readability are requested. Also, the column width for the size
+   output has increased from 11 to 14 characters when human readability is
+   enabled. Use `--no-h` to get the old-style output and column size.
+
+ - The output of the `--progress` option has changed: the string `xfer` was
+   shortened to `xfr`, and the string `to-check` was shortened to `to-chk`,
+   both designed to make room for the (by default) wider display of file size
+   numbers without making the total line-length longer. Also, when incremental
+   recursion is enabled, the string `ir-chk` will be used instead of `to-chk`
+   up until the incremental-recursion scan is done, letting you know that the
+   value to check and the total value will still be increasing as new files are
+   found.
+
+ - Enhanced the `--stats` output: 1) to mention how many files were created
+   (protocol >= 28), 2) to mention how many files were deleted (a new line for
+   protocol 31, but only output when `--delete` is in effect), and 3) to follow
+   the file-count, created-count, and deleted-count with a subcount list that
+   shows the counts by type. The wording of the transferred count has also
+   changed so that it is clearer that it is only a count of regular files.
+
+### BUG FIXES:
+
+ - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a full
+   output buffer.
+
+ - Fixed some rare bugs in `--iconv` processing that might cause a multi-byte
+   character to get translated incorrectly.
+
+ - Fixed a bogus `vanished file` error if some files were specified with `./`
+   prefixes and others were not.
+
+ - Fixed a bug in `--sparse` where an extra gap could get inserted after a
+   partial write.
+
+ - Changed the way `--progress` overwrites its prior output in order to make it
+   nearly impossible for the progress to get overwritten by an error.
+
+ - Improved the propagation of abnormal-exit error messages. This should help
+   the client side to receive errors from the server when it is exiting
+   abnormally, and should also avoid dying with an `connection unexpectedly
+   closed` exit when the closed connection is really expected.
+
+ - The sender now checks each file it plans to remove to ensure that it hasn't
+   changed from the first stat's info. This helps to avoid losing file data
+   when the user is not using the option in a safe manner.
+
+ - Fixed a data-duplication bug in the compress option that made compression
+   less efficient. This improves protocol 31 onward, while behaving in a
+   compatible (buggy) manner with older rsync protocols.
+
+ - When creating a temp-file, rsync is now a bit smarter about it dot-char
+   choices, which can fix a problem on OS X with names that start with `..`.
+
+ - Rsync now sets a cleanup flag for `--inplace` and `--append` transfers that
+   will flush the write buffer if the transfer aborts. This ensures that more
+   received data gets written out to the disk on an aborted transfer (which is
+   quite helpful on a slow, flaky connection).
+
+ - The reads that `map_ptr()` now does are aligned on 1K boundaries. This helps
+   some filesystems and/or files that don't like unaligned reads.
+
+ - Fix an issue in the msleep() function if time jumps backwards.
+
+ - Fix daemon-server module-name splitting bug where an arg would get split
+   even if `--protect-args` was used.
+
+### ENHANCEMENTS:
+
+ - Added the `--remote-option=OPT` (`-M OPT`) command-line option that is
+   useful for things like sending a remote `--log-file=FILE` or `--fake-super`
+   option.
+
+ - Added the `--info=FLAGS` and `--debug=FLAGS` options to allow finer-grained
+   control over what is output. Added an extra type of `--progress` output
+   using `--info=progress2`.
+
+ - The `--msgs2stderr` option can help with debugging rsync by allowing the
+   debug messages to get output to stderr rather than travel via the socket
+   protocol.
+
+ - Added the `--delete-missing-args` and `--ignore-missing-args` options to
+   either delete or ignore user-specified files on the receiver that are
+   missing on the sender (normally the absence of user-specified files
+   generates an error).
+
+ - Added a `T` (terabyte) category to the `--human-readable` size suffixes.
+
+ - Added the `--usermap`/`--groupmap`/`--chown` options for manipulating file
+   ownership during the copy.
+
+ - Added the `%C` escape to the log-output handling, which will output the MD5
+   checksum of any transferred file, or all files if `--checksum` was specified
+   (when protocol 30 or above is in effect).
+
+ - Added the `reverse lookup` parameter to the rsync daemon config file to
+   allow reverse-DNS lookups to be disabled.
+
+ - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can be
+   disabled via `forward lookup` parameter (defaults to enabled).
+
+ - Added a way for more than one group to be specified in the daemon's config
+   file, including a way to specify that you want all of the specified user's
+   groups without having to name them. Also changed the daemon to complain
+   about an inability to set explicitly-specified uid/gid values, even when not
+   run by a super-user.
+
+ - The daemon now tries to send the user the error messages from the pre-xfer
+   exec script when it fails.
+
+ - Improved the use of alt-dest options into an existing hierarchy of files: If
+   a match is found in an alt-dir, it takes precedence over an existing file.
+   (We'll need to wait for a future version before attribute-changes on
+   otherwise unchanged files are safe when using an existing hierarchy.)
+
+ - Added per-user authorization options and group-authorization support to the
+   daemon's `auth users` parameter.
+
+ - Added a way to reference environment variables in a daemon's config file
+   (using %VAR% references).
+
+ - When replacing a non-dir with a symlink/hard-link/device/special-file, the
+   update should now be done in an atomic manner.
+
+ - Avoid re-sending xattr info for hard-linked files w/the same xattrs
+   (protocol 31).
+
+ - The backup code was improved to use better logic maintaining the backup
+   directory hierarchy. Also, when a file is being backed up, rsync tries to
+   hard-link it into place so that the upcoming replacement of the destination
+   file will be atomic (for the normal, non-inplace logic).
+
+ - Added the ability to synchronize nanosecond modified times.
+
+ - Added a few more default suffixes for the `dont compress` settings.
+
+ - Added the checking of the `RSYNC_PROTECT_ARGS` environment variable to allow
+   the default for the `--protect-args` command-line option to be overridden.
+
+ - Added the `--preallocate` command-line option.
+
+ - Allow `--password-file=-` to read the password from stdin (filename `-`).
+
+ - Rsync now comes packaged with an rsync-ssl helper script that can be used to
+   contact a remote rsync daemon using a piped-stunnel command.  It also
+   includes an stunnel config file to run the server side to support ssl daemon
+   connections. See the packaging/lsb/rsync.spec file for one way to package
+   the resulting files. (Suggestions for how to make this even easier to
+   install & use are welcomed.)
+
+ - Improved the speed of some `--inplace` updates when there are lots of
+   identical checksum blocks that end up being unusable.
+
+ - Added the `--outbuf=N|L|B` option for choosing the output buffering.
+
+ - Repeating the `--fuzzy` option now causes the code to look for fuzzy matches
+   inside alt-dest directories too.
+
+ - The `--chmod` option now supports numeric modes, e.g. `--chmod=644,D755`
+
+ - Added some Solaris xattr code.
+
+ - Made an rsync daemon (the listening process) exit with a 0 status when it
+   was signaled to die. This helps launchd.
+
+ - Improved the `RSYNC_*` environment variables for the pre-xfer exec script:
+   when a daemon is sent multiple request args, they are now joined into a
+   single return value (separated by spaces) so that the `RSYNC_REQUEST`
+   environment variable is accurate for any `pre-xfer exec`. The values in
+   `RSYNC_ARG#` vars are no longer truncated at the `.` arg (prior to the
+   request dirs/files), so that all the requested values are also listed
+   (separately) in `RSYNC_ARG#` variables.
+
+### EXTRAS:
+
+ - Added an `instant-rsyncd` script to the support directory, which makes it
+   easy to configure a simple rsync daemon in the current directory.
+
+ - Added the `mapfrom` and `mapto` scripts to the support directory, which
+   makes it easier to do user/group mapping in a local transfer based on
+   passwd/group files from another machine.
+
+ - There's a new, improved version of the lsh script in the support dir: it's
+   written in perl and supports `-u` without resorting to using sudo (when run
+   as root). The old shell version is now named lsh.sh.
+
+ - There is a helper script named rsync-slash-strip in the support directory
+   for anyone that wants to change the way rsync handles args with trailing
+   slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into
+   arg/).
+
+### INTERNAL:
+
+ - The I/O code was rewritten to be simpler and do bigger buffered reads over
+   the socket. The I/O between the receiver and the generator was changed to be
+   standard multiplexed-I/O (like that over the socket).
+
+ - The sender tries to use any dead time while the generator is looking for
+   files to transfer in order to do sender-side directory scanning in a more
+   parallel manner.
+
+ - A daemon can now inform a client about a daemon-configured timeout value so
+   that the client can assist in the keep-alive activity (protocol 31).
+
+ - The filter code received some refactoring to make it more extendable, to
+   read better, and do better sanity checking.
+
+ - Really big numbers are now output using our own big-num routine rather than
+   casting them to a double and using a %.0f conversion.
+
+ - The `pool_alloc` library has received some minor improvements in alignment
+   handling.
+
+ - Added `init_stat_x()` function to avoid duplication of acl/xattr init code.
+
+ - The included zlib was upgraded from 1.2.3 to 1.2.8.
+
+ - Rsync can now be compiled to use an unmodified zlib library instead of the
+   tweaked one that is included with rsync. This will eventually become the
+   default, at which point we'll start the countdown to removing the included
+   zlib. Until then, feel free to configure using:
+
+   ./configure `--with-included-zlib=no`
+
+### DEVELOPER RELATED:
+
+ - Added more conditional debug output.
+
+ - Fixed some build issues for Android and Minix.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.0.9 (23 Sep 2011)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Fix a crash bug in checksum scanning when `--inplace` is used.
+
+ - Fix a hang if a hard-linked file cannot be opened by the sender (e.g.  if it
+   has no read permission).
+
+ - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
+
+ - Fix a memory leak in the xattr code.
+
+ - Fixed a bug with `--delete-excluded` when a filter merge file has a rule
+   that specifies a receiver-only side restriction.
+
+ - Fix a bug with the modifying of unwritable directories.
+
+ - Fix `--fake-super`'s interaction with `--link-dest` same-file comparisons.
+
+ - Fix the updating of the `curr_dir` buffer to avoid a duplicate slash.
+
+ - Fix the directory permissions on an implied dot-dir when using `--relative`
+   (e.g. /outside/path/././send/path).
+
+ - Fixed some too-long sleeping instances when using `--bwlimit`.
+
+ - Fixed when symlink ownership difference-checking gets compiled into
+   `unchanged_attrs()`.
+
+ - Improved the socket-error reporting when multiple protocols fail.
+
+ - Fixed a case where a socket error could reference just-freed memory.
+
+ - Failing to use a password file that was specified on the command-line is now
+   a fatal error.
+
+ - Fix the non-root updating of directories that don't have the read and/or
+   execute permission.
+
+ - Make daemon-excluded file errors more error-like.
+
+ - Fix a compilation issue on older C compilers (due to a misplaced var
+   declaration).
+
+ - Make configure avoid finding socketpair on Cygwin.
+
+ - Avoid trying to reference `SO_BROADCAST` if the OS doesn't support it.
+
+ - Fix some issues with the post-processing of the manpages.
+
+ - Fixed the user home-dir handling in the lsh script. (See the support dir.)
+
+ - Some minor manpage improvements.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.0.8 (26 Mar 2011)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Fixed two buffer-overflow issues: one where a directory path that is exactly
+   MAXPATHLEN was not handled correctly, and one handling a `--backup-dir` that
+   is extra extra large.
+
+ - Fixed a data-corruption issue when preserving hard-links without preserving
+   file ownership, and doing deletions either before or during the transfer
+   (CVE-2011-1097). This fixes some assert errors in the hard-linking code, and
+   some potential failed checksums (via `-c`) that should have matched.
+
+ - Fixed a potential crash when an rsync daemon has a filter/exclude list and
+   the transfer is using ACLs or xattrs.
+
+ - Fixed a hang if a really large file is being processed by an rsync that
+   can't handle 64-bit numbers. Rsync will now complain about the file being
+   too big and skip it.
+
+ - For devices and special files, we now avoid gathering useless ACL and/or
+   xattr information for files that aren't being copied. (The un-copied files
+   are still put into the file list, but there's no need to gather data that is
+   not going to be used.) This ensures that if the user uses `--no-D`, that
+   rsync can't possibly complain about being unable to gather extended
+   information from special files that are in the file list (but not in the
+   transfer).
+
+ - Properly handle requesting remote filenames that start with a dash. This
+   avoids a potential error where a filename could be interpreted as a (usually
+   invalid) option.
+
+ - Fixed a bug in the comparing of upper-case letters in file suffixes for
+   `--skip-compress`.
+
+ - If an rsync daemon has a module configured without a path setting, rsync
+   will now disallow access to that module.
+
+ - If the destination arg is an empty string, it will be treated as a reference
+   to the current directory (as 2.x used to do).
+
+ - If rsync was compiled with a newer time-setting function (such as lutimes),
+   rsync will fall-back to an older function (such as utimes) on a system where
+   the newer function is not around. This helps to make the rsync binary more
+   portable in mixed-OS-release situations.
+
+ - Fixed a batch-file writing bug that would not write out the full set of
+   compatibility flags that the transfer was using. This fixes a potential
+   protocol problem for a batch file that contains a sender-side I/O error: it
+   would have been sent in a way that the batch-reader wasn't expecting.
+
+ - Some improvements to the hard-linking code to ensure that device-number
+   hashing is working right, and to supply more information if the hard-link
+   code fails.
+
+ - The `--inplace` code was improved to not search for an impossible checksum
+   position. The quadruple-verbose chunk[N] message will now mention when an
+   inplace chunk was handled by a seek rather than a read+write.
+
+ - Improved ACL mask handling, e.g. for Solaris.
+
+ - Fixed a bug that prevented `--numeric-ids` from disabling the translation of
+   user/group IDs for ACLs.
+
+ - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
+   option (e.g. `--link-dest`) could output an error trying to itemize the
+   changes against the alt-dest directory's xattr/ACL info but was instead
+   trying to access the not-yet-existing new destination directory.
+
+ - Improved xattr system-error messages to mention the full path to the file.
+
+ - The `--link-dest` checking for identical symlinks now avoids considering
+   attribute differences that cannot be changed on the receiver.
+
+ - Avoid trying to read/write xattrs on certain file types for certain OSes.
+   Improved configure to set `NO_SYMLINK_XATTRS`, `NO_DEVICE_XATTRS`, and/or
+   `NO_SPECIAL_XATTRS` defines in config.h.
+
+ - Improved the unsafe-symlink errors messages.
+
+ - Fixed a bug setting xattrs on new files that aren't user writable.
+
+ - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
+
+ - Fixed a bug with `--fake-super` when copying files and dirs that aren't user
+   writable.
+
+ - Fixed a bug where a sparse file could have its last sparse block turned into
+   a real block when rsync sets the file size (requires ftruncate).
+
+ - If a temp-file name is too long, rsync now avoids truncating the name in the
+   middle of adjacent high-bit characters. This prevents a potential filename
+   error if the filesystem doesn't allow a name to contain an invalid
+   multi-byte sequence.
+
+ - If a muli-protocol socket connection fails (i.e., when contacting a daemon),
+   we now report all the failures, not just the last one. This avoids losing a
+   relevant error (e.g. an IPv4 connection-refused error) that happened before
+   the final error (e.g. an IPv6 protocol-not-supported error).
+
+ - Generate a transfer error if we try to call chown with a `-1` for a uid or a
+   gid (which is not settable).
+
+ - Fixed the working of `--force` when used with `--one-file-system`.
+
+ - Fix the popt arg parsing so that an option that doesn't take an arg will
+   reject an attempt to supply one (can configure `--with-included-popt` if
+   your system's popt library doesn't yet have this fix).
+
+ - A couple minor option tweaks to the rrsync script, and also some regex
+   changes that make vim highlighting happier. (See the support dir.)
+
+ - Fixed some issues in the mnt-excl script. (See the support dir.)
+
+ - Various manpage improvements.
+
+### ENHANCEMENTS:
+
+ - Added `.hg/` to the default cvs excludes (see `-C` & `--cvs-exclude`).
+
+### DEVELOPER RELATED:
+
+ - Use lchmod() whenever it is available (not just on symlinks).
+
+ - A couple fixes to the `socketpair_tcp()` routine.
+
+ - Updated the helper scripts in the packaging subdirectory.
+
+ - Renamed configure.in to configure.ac.
+
+ - Fixed configure's checking for iconv routines for newer OS X versions.
+
+ - Fixed the testsuite/xattrs.test script on OS X.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.0.7 (31 Dec 2009)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Fixed a bogus free when using `--xattrs` with `--backup`.
+
+ - Avoid an error when `--dry-run` was trying to stat a prior hard-link file
+   that hasn't really been created.
+
+ - Fixed a problem with `--compress` (`-z`) where the receiving side could
+   return the error "`inflate (token) returned -5`".
+
+ - Fixed a bug where `--delete-during` could delete in a directory before it
+   noticed that the sending side sent an I/O error for that directory (both
+   sides of the transfer must be at least 3.0.7).
+
+ - Improved `--skip-compress`'s error handling of bad character-sets and got
+   rid of a lingering debug fprintf().
+
+ - Fixed the daemon's conveyance of `io_error` value from the sender.
+
+ - An rsync daemon use seteuid() (when available) if it used setuid().
+
+ - Get the permissions right on a `--fake-super` transferred directory that
+   needs more owner permissions to emulate root behavior.
+
+ - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses its
+   modifier when sending the filter rules to the remote rsync.
+
+ - Improved the "`--delete does not work without -r or -d`" message.
+
+ - Improved rsync's handling of `--timeout` to avoid a weird timeout case where
+   the sender could timeout even though it has recently written data to the
+   socket (but hasn't read data recently, due to the writing).
+
+ - Some misc manpage improvements.
+
+ - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
+
+ - Make sure that a timeout specified in the daemon's config is used as a
+   maximum timeout value when the user also specifies a timeout.
+
+ - Improved the error-exit reporting when rsync gets an error trying to cleanup
+   after an error: the initial error is reported.
+
+ - Improved configure's detection of IPv6 for Solaris and Cygwin.
+
+ - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
+
+ - Made our (only used if missing) getaddrinfo() routine use `inet_pton()`
+   (which we also provide) instead of `inet_aton()`.
+
+ - The exit-related debug messages now mention the program's role so it is
+   clear who output what message.
+
+### DEVELOPER RELATED:
+
+ - Got rid of type-punned compiler warnings output by newer gcc versions.
+
+ - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
+
+ - The testsuite no longer uses `id -u`, so it works better on Solaris.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.0.6 (8 May 2009)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Fixed a `--read-batch` hang when rsync is reading a batch file that was
+   created from an incremental-recursion transfer.
+
+ - Fixed the daemon's socket code to handle the simultaneous arrival of
+   multiple connections.
+
+ - Fix `--safe-links`/`--copy-unsafe-links` to properly handle symlinks that
+   have consecutive slashes in the value.
+
+ - Fixed the parsing of an `[IPv6_LITERAL_ADDR]` when a USER@ is prefixed.
+
+ - The sender now skips a (bogus) symlink that has a 0-length value, which
+   avoids a transfer error in the receiver.
+
+ - Fixed a case where the sender could die with a tag-0 error if there was an
+   I/O during the sending of the file list.
+
+ - Fixed the rrsync script to avoid a server-side problem when `-e` is at the
+   start of the short options.
+
+ - Fixed a problem where a vanished directory could turn into an exit code 23
+   instead of the proper exit code 24.
+
+ - Fixed the `--iconv` conversion of symlinks when doing a local copy.
+
+ - Fixed a problem where `--one-file-system` was not stopping deletions on the
+   receiving side when a mount-point directory did not match a directory in the
+   transfer.
+
+ - Fixed the dropping of an ACL mask when no named ACL values were present.
+
+ - Fixed an ACL/xattr corruption issue where the `--backup` option could cause
+   rsync to associate the wrong ACL/xattr information with received files.
+
+ - Fixed the use of `--xattrs` with `--only-write-batch`.
+
+ - Fixed the use of `--dry-run` with `--read-batch`.
+
+ - Fixed configure's erroneous use of target.
+
+ - Fixed configure's `--disable-debug` option.
+
+ - Fixed a run-time issue for systems that can't find `iconv_open()` by adding
+   the `--disable-iconv-open` configure option.
+
+ - Complain and die if the user tries to combine `--remove-source-files` (or
+   the deprecated `--remove-sent-files`) with `--read-batch`.
+
+ - Fixed an failure transferring special files from Solaris to Linux.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.0.5 (28 Dec 2008)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Initialize xattr data in a couple spots in the hlink code, which avoids a
+   crash when the xattr pointer's memory happens to start out non-zero.  Also
+   fixed the itemizing of an alt-dest file's xattrs when hard-linking.
+
+ - Don't send a bogus `-` option to an older server if there were no short
+   options specified.
+
+ - Fixed skipping of unneeded updates in a batch file when incremental
+   recursion is active. Added a test for this. Made batch-mode handle `redo`
+   files properly (and without hanging).
+
+ - Fix the %P logfile escape when the daemon logs from inside a chroot.
+
+ - Fixed the use of `-s` (`--protect-args`) when used with a remote source or
+   destination that had an empty path (e.g. `host:`). Also fixed a problem when
+   `-s` was used when accessing a daemon via a remote-shell.
+
+ - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a `--files-from`
+   file when the root of the transfer isn't the current directory.
+
+ - Fixed a bug with `-K --delete` removing symlinks to directories when
+   incremental recursion is active.
+
+ - Fixed a hard to trigger hang when using `--remove-source-files`.
+
+ - Got rid of an annoying delay when accessing a daemon via a remote-shell.
+
+ - Properly ignore (superfluous) source args on a `--read-batch` command.
+
+ - Improved the manpage's description of the `*` wildcard to remove the
+   confusing `non-empty` qualifier.
+
+ - Fixed reverse lookups in the compatibility-library version of getnameinfo().
+
+ - Fixed a bug when using `--sparse` on a sparse file that has over 2GB of
+   consecutive sparse data.
+
+ - Avoid a hang when using at least 3 `--verbose` options on a transfer with a
+   client sender (which includes local copying).
+
+ - Fixed a problem with `--delete-delay` reporting an error when it was ready
+   to remove a directory that was now gone.
+
+ - Got rid of a bunch of `warn_unused_result` compiler warnings.
+
+ - If an ftruncate() on a received file fails, it now causes a partial-
+   transfer warning.
+
+ - Allow a path with a leading `//` to be preserved (CYGWIN only).
+
+### ENHANCEMENTS:
+
+ - Made the atomic-rsync script able to perform a fully atomic update of the
+   copied hierarchy when the destination is setup using a particular symlink
+   idiom. (See the support dir.)
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.0.4 (6 Sep 2008)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Fixed a bug in the hard-linking code where it would sometimes try to
+   allocate 0 bytes of memory (which fails on some OSes, such as AIX).
+
+ - Fixed the hard-linking of files from a device that has a device number of 0
+   (which seems to be a common device number on NetBSD).
+
+ - Fixed the handling of a `--partial-dir` that cannot be created. This
+   particularly impacts the `--delay-updates` option (since the files cannot be
+   delayed without a partial-dir), and was potentially destructive if the
+   `--remove-source-files` was also specified.
+
+ - Fixed a couple issues in the `--fake-super` handling of xattrs when the
+   destination files have root-level attributes (e.g. selinux values) that a
+   non-root copy can't affect.
+
+ - Improved the keep-alive check in the generator to fire consistently in
+   incremental-recursion mode when `--timeout` is enabled.
+
+ - The `--iconv` option now converts the content of a symlink too, instead of
+   leaving it in the wrong character-set (requires 3.0.4 on both sides of the
+   transfer).
+
+ - When using `--iconv`, if a filename fails to convert on the receiving side,
+   this no longer makes deletions in the root-dir of the transfer fail silently
+   (the user now gets a warning about deletions being disabled due to IO error
+   as long as `--ignore-errors` was not specified).
+
+ - When using `--iconv`, if a server-side receiver can't convert a filename,
+   the error message sent back to the client no longer mangles the name with
+   the wrong charset conversion.
+
+ - Fixed a potential alignment issue in the IRIX ACL code when allocating the
+   initial `struct acl` object. Also, cast mallocs to avoid warnings.
+
+ - Changed some errors that were going to stdout to go to stderr.
+
+ - Made `human_num()` and `human_dnum()` able to output a negative number
+   (rather than outputting a cryptic string of punctuation).
+
+### ENHANCEMENTS:
+
+ - Rsync will avoid sending an `-e` option to the server if an older protocol
+   is requested (and thus the option would not be useful). This lets the user
+   specify the `--protocol=29` option to access an overly-restrictive server
+   that is rejecting the protocol-30 use of `-e` to the server.
+
+ - Improved the message output for an `RERR_PARTIAL` exit.
+
+### DEVELOPER RELATED:
+
+ - The Makefile will not halt for just a timestamp change on the Makefile or
+   the configure files, only for actual changes in content.
+
+ - Changed some commands in the testsuite's xattrs.test that called `rsync`
+   instead of `$RSYNC`.
+
+ - Enhanced the release scripts to be able to handle a branch release and to do
+   even more consistency checks on the files.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.0.3 (29 Jun 2008)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Fixed a wildcard matching problem in the daemon when a module has `use
+   chroot` enabled.
+
+ - Fixed a crash bug in the hard-link code.
+
+ - Fixed the sending of xattr directory information when the code finds a
+   `--link-dest` or `--copy-dest` directory with unchanged xattrs -- the
+   destination directory now gets these unchanged xattrs properly applied.
+
+ - Fixed an xattr-sending glitch that could cause an `Internal abbrev` error.
+
+ - Fixed the combination of `--xattrs` and `--backup`.
+
+ - The generator no longer allows a '.' dir to be excluded by a daemon-exclude
+   rule.
+
+ - Fixed deletion handling when copying a single, empty directory (with no
+   files) to a differently named, non-existent directory.
+
+ - Fixed the conversion of spaces into dashes in the %M log escape.
+
+ - Fixed several places in the code that were not returning the right errno
+   when a function failed.
+
+ - Fixed the backing up of a device or special file into a backup dir.
+
+ - Moved the setting of the socket options prior to the connect().
+
+ - If rsync exits in the middle of a `--progress` output, it now outputs a
+   newline to help prevent the progress line from being overwritten.
+
+ - Fixed a problem with how a destination path with a trailing slash or a
+   trailing dot-dir was compared against the daemon excludes.
+
+ - Fixed the sending of large (size > 16GB) files when talking to an older
+   rsync (protocols < 30): we now use a compatible block size limit.
+
+ - If a file's length is so huge that we overflow a checksum buffer count (i.e.
+   several hundred TB), warn the user and avoid sending an invalid checksum
+   struct over the wire.
+
+ - If a source arg is excluded, `--relative` no longer adds the excluded arg's
+   implied dirs to the transfer. This fix also made the exclude check happen in
+   the better place in the sending code.
+
+ - Use the `overflow_exit()` function for overflows, not `out_of_memory()`.
+
+ - Improved the code to better handle a system that has only 32-bit file
+   offsets.
+
+### ENHANCEMENTS:
+
+ - The rsyncd.conf manpage now consistently refers to the parameters in the
+   daemon config file as `parameters`.
+
+ - The description of the `--inplace` option was improved.
+
+### EXTRAS:
+
+ - Added a new script in the support directory, deny-rsync, which allows an
+   admin to (temporarily) replace the rsync command with a script that sends an
+   error message to the remote client via the rsync protocol.
+
+### DEVELOPER RELATED:
+
+ - Fixed a testcase failure if the tests are run as root and made some
+   compatibility improvements.
+
+ - Improved the daemon tests, including checking module comments, the listing
+   of files, and the ensuring that daemon excludes can't affect a dot-dir arg.
+
+ - Improved some build rules for those that build in a separate directory from
+   the source, including better install rules for the manpages, and the fixing
+   of a proto.h-tstamp rule that could make the binaries get rebuild without
+   cause.
+
+ - Improved the testsuite to work around a problem with some utilities (e.g.
+   `cp -p` & `touch -r`) rounding sub-second timestamps.
+
+ - Ensure that the early patches don't cause any generated-file hunks to
+   bleed-over into patches that follow.

+
+ - Fixed a potential buffer overflow in the xattr code.
+
+### ENHANCEMENTS:
+
+ - None.
+

+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.0.1 (3 Apr 2008)
+
+## Changes in this version:
+
+### NOTABLE CHANGES IN BEHAVIOR:
+
+ - Added the 'c'-flag to the itemizing of non-regular files so that the
+   itemized output doesn't get hidden if there were no attribute changes, and
+   also so that the itemizing of a `--copy-links` run will distinguish between
+   copying an identical non-regular file and the creation of a revised version
+   with a new value (e.g. a changed symlink referent, a new device number,
+   etc.).
+
+### BUG FIXES:
+
+ - Fixed a crash bug when a single-use rsync daemon (via remote shell) was run
+   without specifying a `--config=FILE` option.
+
+ - Fixed a crash when backing up a directory that has a default ACL.
+
+ - Fixed a bug in the handling of xattr values that could cause rsync to not
+   think that a file's extended attributes are up-to-date.
+
+ - Fixed the working of `--fake-super` with `--link-dest` and `--xattrs`.
+
+ - Fixed a hang when combining `--dry-run` with `--remove-source-files`.
+
+ - Fixed a bug with `--iconv`'s handling of files that cannot be converted: a
+   failed name can no longer cause a transfer failure.
+
+ - Fixed the building of the rounding.h file on systems that need custom
+   CPPFLAGS to be used. Also improved the error reporting if the building of
+   rounding.h fails.
+
+ - Fixed the use of the `--protect-args` (`-s`) option when talking to a
+   daemon.
+
+ - Fixed the `--ignore-existing` option's protection of files on the receiver
+   that are non-regular files on the sender (e.g. if a symlink or a dir on the
+   sender is trying to replace a file on the receiver). The reverse protection
+   (protecting a dir/symlink/device from being replaced by a file) was already
+   working.
+
+ - Fixed an assert failure if `--hard-links` is combined with an option that
+   can skip a file in a set of hard-linked files (i.e. `--ignore-existing`,
+   `--append`, etc.), without skipping all the files in the set.
+
+ - Avoid setting the modify time on a directory that already has the right
+   modify time set. This avoids tweaking the dir's ctime.
+
+ - Improved the daemon-exclude handling to do a better job of applying the
+   exclude rules to path entries. It also sends the user an error just as if
+   the files were actually missing (instead of silently ignoring the user's
+   args), and avoids sending the user the filter-action messages for these
+   non-user-initiated rules.
+
+ - Fixed some glitches with the dry-run code's missing-directory handling,
+   including a problem when combined with `--fuzzy`.
+
+ - Fixed some glitches with the skipped-directory handling.
+
+ - Fixed the 'T'-flag itemizing of symlinks when `--time` isn't preserved.
+
+ - Fixed a glitch in the itemizing of permissions with the `-E` option.
+
+ - The `--append` option's restricting of transfers to those that add data no
+   longer prevents the updating of non-content changes to otherwise up-to-date
+   files (i.e. those with the same content but differing permissions,
+   ownership, xattrs, etc.).
+
+ - Don't allow `--fake-super` to be specified with `-XX` (double `--xattrs`)
+   because the options conflict. If a daemon has `fake super` enabled, it
+   automatically downgrades a `-XX` request to `-X`.
+
+ - Fixed a couple bugs in the parsing of daemon-config excludes that could make
+   a floating exclude rule get treated as matching an absolute path.
+
+ - A daemon doesn't try to auto-refuse the `iconv` option if iconv-support
+   wasn't compiled in to the daemon (avoiding a warning in the logs).
+
+ - Fixed the inclusion of per-dir merge files from implied dirs.
+
+ - Fixed the rrsync script to work with the latest options that rsync sends,
+   including its flag-specifying use of `-e` to the server. (See the support
+   dir.)
+
+### ENHANCEMENTS:
+
+ - Added the `--old-dirs` (`--old-d`) option to make it easier for a user to
+   ask for file-listings with older rsync versions (this is easier than having
+   to type `-r --exclude='/*/*'` manually).
+
+ - When getting an error while asking an older rsync daemon for a file listing,
+   rsync will try to notice if the error is a rejection of the `--dirs` (`-d`)
+   option and let the user know how to work around the issue.
+
+ - Added a few more `--no-OPTION` overrides.
+
+ - Improved the documentation of the `--append` option.
+
+ - Improved the documentation of the filter/exclude/include daemon parameters.
+
+### INTERNAL:
+
+ - Fixed a couple minor bugs in the included popt library (ones which I sent to
+   the official popt project for inclusion in the 1.14 release).
+
+ - Fixed a stat() call that should have been `do_stat()` so that the proper
+   normal/64-bit stat() function gets called. (Was in an area that should not
+   have caused problems, though.)
+
+ - Changed the file-glob code to do a directory scan without using the `glob`
+   and `glob.h`. This lets us do the globbing with less memory churn, and also
+   avoid adding daemon-excluded items to the returned args.
+
+### DEVELOPER RELATED:
+
+ - The configure script tries to get the user's compiler to not warn about
+   unused function parameters if the build is not including one or more of the
+   ACL/xattrs/iconv features.
+
+ - The configure script now has better checks for figuring out if the included
+   popt code should be used or not.
+
+ - Fixed two testsuite glitches: avoid a failure if someone's `cd` command
+   outputs the current directory when cd-ing to a relative path, and made the
+   itemized test query how rsync was built to determine if it should expect
+   hard-linked symlinks or not.
+
+ - Updated the testsuite to verify that various bug fixes remain fixed.
+
+ - The RPM spec file was updated to have: (1) comments for how to use the
+   rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
+
+ - Updated the build scripts to work with a revised FTP directory structure.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 3.0.0 (1 Mar 2008)
+
+## Changes in this version:
+
+### PROTOCOL NUMBER:
+
+ - The protocol number was changed to 30.
+
+### NOTABLE CHANGES IN BEHAVIOR:
+
+ - The handling of implied directories when using `--relative` has changed to
+   send them as directories (e.g. no implied dir is ever sent as a symlink).
+   This avoids unexpected behavior and should not adversely affect most people.
+   If you're one of those rare individuals who relied upon having an implied
+   dir be duplicated as a symlink, you should specify the transfer of the
+   symlink and the transfer of the referent directory as separate args. (See
+   also `--keep-dirlinks` and `--no-implied-dirs`.) Also, exclude rules no
+   longer have a partial effect on implied dirs.
+
+ - Requesting a remote file-listing without specifying `-r` (`--recursive`) now
+   sends the `-d` (`--dirs`) option to the remote rsync rather than sending
+   `-r` along with an extra exclude of `/*/*`. If the remote rsync does not
+   understand the `-d` option (i.e. it is 2.6.3 or older), you will need to
+   either turn off `-d` (`--no-d`), or specify `-r --exclude='/*/*'` manually.
+
+ - In `--dry-run` mode, the last line of the verbose summary text is output
+   with a "(DRY RUN)" suffix to help remind you that no updates were made.
+   Similarly, `--only-write-batch` outputs `(BATCH ONLY)`.
+
+ - A writable rsync daemon with `use chroot` disabled now defaults to a
+   symlink-munging behavior designed to make symlinks safer while also allowing
+   absolute symlinks to be stored and retrieved. This also has the effect of
+   making symlinks unusable while they're in the daemon's hierarchy. See the
+   daemon's `munge symlinks` parameter for details.
+
+ - Starting up an extra copy of an rsync daemon will not clobber the pidfile
+   for the running daemon -- if the pidfile exists, the new daemon will exit
+   with an error. This means that your wrapper script that starts the rsync
+   daemon should be made to handle lock-breaking (if you want any automatic
+   breaking of locks to be done).
+
+### BUG FIXES:
+
+ - A daemon with `use chroot = no` and excluded items listed in the daemon
+   config file now properly checks an absolute-path arg specified for these
+   options: `--compare-dest`, `--link-dest`, `--copy-dest`, `--partial-dir`,
+   `--backup-dir`, `--temp-dir`, and `--files-from`.
+
+ - A daemon can now be told to disable all user- and group-name translation on
+   a per-module basis. This avoids a potential problem with a writable daemon
+   module that has `use chroot` enabled -- if precautions weren't taken, a user
+   could try to add a missing library and get rsync to use it. This makes rsync
+   safer by default, and more configurable when id-translation is not desired.
+   See the daemon's `numeric ids` parameter for full details.
+
+ - A chroot daemon can now indicate which part of its path should affect the
+   chroot call, and which part should become an inside-chroot path for the
+   module. This allows you to have outside-the-transfer paths (such as for
+   libraries) even when you enable chroot protection. The idiom used in the
+   rsyncd.conf file is: `path = /chroot/dirs/./dirs/inside`
+
+ - If a file's data arrived successfully on the receiving side but the rename
+   of the temporary file to the destination file failed AND the
+   `--remove-source-files` (or the deprecated `--remove-sent-files`) option was
+   specified, rsync no longer erroneously removes the associated source file.
+
+ - Fixed the output of `-ii` when combined with one of the `--*-dest` options:
+   it now itemizes all the items, not just the changed ones.
+
+ - Made the output of all file types consistent when using a `--*-dest` option.
+   Prior versions would output too many creation events for matching items.
+
+ - The code that waits for a child pid now handles being interrupted by a
+   signal. This fixes a problem with the pre-xfer exec function not being able
+   to get the exit status from the script.
+
+ - A negated filter rule (i.e. with a '!' modifier) no longer loses the
+   negation when sending the filter rules to the remote rsync.
+
+ - Fixed a problem with the `--out-format` (aka `--log-format`) option %f: it
+   no longer outputs superfluous directory info for a non-daemon rsync.
+
+ - Fixed a problem with `-vv` (double `--verbose`) and `--stats` when `pushing`
+   files (which includes local copies). Version 2.6.9 would complete the copy,
+   but exit with an error when the receiver output its memory stats.
+
+ - If `--password-file` is used on a non-daemon transfer, rsync now complains
+   and exits. This should help users figure out that they can't use this option
+   to control a remote shell's password prompt.
+
+ - Make sure that directory permissions of a newly-created destination
+   directory are handled right when `--perms` is left off.
+
+ - The itemized output of a newly-created destination directory is now output
+   as a creation event, not a change event.
+
+ - Improved `--hard-link` so that more corner cases are handled correctly when
+   combined with options such as `--link-dest` and/or `--ignore-existing`.
+
+ - The `--append` option no longer updates a file that has the same size.
+
+ - Fixed a bug when combining `--backup` and `--backup-dir` with `--inplace`:
+   any missing backup directories are now created.
+
+ - Fixed a bug when using `--backup` and `--inplace` with `--whole-file` or
+   `--read-batch`: backup files are actually created now.
+
+ - The daemon pidfile is checked and created sooner in the startup sequence.
+
+ - If a daemon module's `path` value is not an absolute pathname, the code now
+   makes it absolute internally (making it work properly).
+
+ - Ensure that a temporary file always has owner-write permission while we are
+   writing to it. This avoids problems with some network filesystems when
+   transferring read-only files.
+
+ - Any errors output about password-file reading no longer cause an error at
+   the end of the run about a partial transfer.
+
+ - The `--read-batch` option for protocol 30 now ensures that several more
+   options are set correctly for the current batch file: `--iconv`, `--acls`,
+   `--xattrs`, `--inplace`, `--append`, and `--append-verify`.
+
+ - Using `--only-write-batch` to a daemon receiver now works properly (older
+   versions would update some files while writing the batch).
+
+ - Avoid outputting a "file has vanished" message when the file is a broken
+   symlink and `--copy-unsafe-links` or `--copy-dirlinks` is used (the code
+   already handled this for `--copy-links`).
+
+ - Fixed the combination of `--only-write-batch` and `--dry-run`.
+
+ - Fixed rsync's ability to remove files that are not writable by the file's
+   owner when rsync is running as the same user.
+
+ - When transferring large files, the sender's hashtable of checksums is kept
+   at a more reasonable state of fullness (no more than 80% full) so that the
+   scanning of the hashtable will not bog down as the number of blocks
+   increases.
+
+### ENHANCEMENTS:
+
+ - A new incremental-recursion algorithm is now used when rsync is talking to
+   another 3.x version. This starts the transfer going more quickly (before all
+   the files have been found), and requires much less memory.  See the
+   `--recursive` option in the manpage for some restrictions.
+
+ - Lowered memory use in the non-incremental-recursion algorithm for typical
+   option values (usually saving from 21-29 bytes per file).
+
+ - The default `--delete` algorithm is now `--delete-during` when talking to a
+   3.x rsync. This is a faster scan than using `--delete-before` (which is the
+   default when talking to older rsync versions), and is compatible with the
+   new incremental recursion mode.
+
+ - Rsync now allows multiple remote-source args to be specified rather than
+   having to rely on a special space-splitting side-effect of the remote-
+   shell. Additional remote args must specify the same host or an empty one
+   (e.g. empty: `:file1` or `::module/file2`). For example, this means that
+   local use of brace expansion now works: `rsync -av host:dir/{f1,f2} .`
+
+ - Added the `--protect-args` (`-s`) option, that tells rsync to send most of
+   the command-line args at the start of the transfer rather than as args to
+   the remote-shell command. This protects them from space-splitting, and only
+   interprets basic wildcard special shell characters (`*?[`).
+
+ - Added the `--delete-delay` option, which is a more efficient way to delete
+   files at the end of the transfer without needing a separate delete pass.
+
+ - Added the `--acls` (`-A`) option to preserve Access Control Lists. This is
+   an improved version of the prior patch that was available, and it even
+   supports OS X ACLs. If you need to have backward compatibility with old,
+   ACL-patched versions of rsync, apply the acls.diff file from the patches
+   dir.
+
+ - Added the `--xattrs` (`-X`) option to preserve extended attributes. This is
+   an improved version of the prior patch that was available, and it even
+   supports OS X xattrs (which includes their resource fork data). If you need
+   to have backward compatibility with old, xattr-patched versions of rsync,
+   apply the xattrs.diff file from the patches dir.
+
+ - Added the `--fake-super` option that allows a non-super user to preserve all
+   attributes of a file by using a special extended-attribute idiom.  It even
+   supports the storing of foreign ACL data on your backup server.  There is
+   also an analogous `fake super` parameter for an rsync daemon.
+
+ - Added the `--iconv` option, which allows rsync to convert filenames from one
+   character-set to another during the transfer. The default is to make this
+   feature available as long as your system has `iconv_open()`.  If compilation
+   fails, specify `--disable-iconv` to configure, and then rebuild. If you want
+   rsync to perform character-set conversions by default, you can specify
+   `--enable-iconv=CONVERT_STRING` with the default value for the `--iconv`
+   option that you wish to use. For example, `--enable-iconv=.` is a good
+   choice. See the rsync manpage for an explanation of the `--iconv` option's
+   settings.
+
+ - A new daemon config parameter, `charset`, lets you control the character-
+   set that is used during an `--iconv` transfer to/from a daemon module. You
+   can also set your daemon to refuse `no-iconv` if you want to force the
+   client to use an `--iconv` transfer (requiring an rsync 3.x client).
+
+ - Added the `--skip-compress=LIST` option to override the default list of file
+   suffixes that will not be compressed when using `--compress` (`-z`).
+
+ - The daemon's default for `dont compress` was extended to include: `*.7z`
+   `*.mp[34]` `*.mov` `*.avi` `*.ogg` `*.jpg` `*.jpeg` and the name-matching routine was also
+   optimized to run more quickly.
+
+ - The `--max-delete` option now outputs a warning if it skipped any file
+   deletions, including a count of how many deletions were skipped. (Older
+   versions just silently stopped deleting things.)
+
+ - You may specify `--max-delete=0` to a 3.0.0 client to request that it warn
+   about extraneous files without deleting anything. If you're not sure what
+   version the client is, you can use the less-obvious `--max-delete=-1`, as
+   both old and new versions will treat that as the same request (though older
+   versions don't warn).
+
+ - The `--hard-link` option now uses less memory on both the sending and
+   receiving side for all protocol versions. For protocol 30, the use of a
+   hashtable on the sending side allows us to more efficiently convey to the
+   receiver what files are linked together. This reduces the amount of data
+   sent over the socket by a considerable margin (rather than adding more
+   data), and limits the in-memory storage of the device+inode information to
+   just the sending side for the new protocol 30, or to the receiving side when
+   speaking an older protocol (note that older rsync versions kept the
+   device+inode information on both sides).
+
+ - The filter rules now support a perishable (`p`) modifier that marks rules
+   that should not have an effect in a directory that is being deleted. e.g.
+   `-f '-p .svn/'` would only affect `live` .svn directories.
+
+ - Rsync checks all the alternate-destination args for validity (e.g.
+   `--link-dest`). This lets the user know when they specified a directory that
+   does not exist.
+
+ - If we get an ENOSYS error setting the time on a symlink, we don't complain
+   about it anymore (for those systems that even support the setting of the
+   modify-time on a symlink).
+
+ - Protocol 30 now uses MD5 checksums instead of MD4.
+
+ - Changed the `--append` option to not checksum the existing data in the
+   destination file, which speeds up file appending.
+
+ - Added the `--append-verify` option, which works like the older `--append`
+   option (verifying the existing data in the destination file). For
+   compatibility with older rsync versions, any use of `--append` that is
+   talking protocol 29 or older will revert to the `--append-verify` method.
+
+ - Added the `--contimeout=SECONDS` option that lets the user specify a
+   connection timeout for rsync daemon access.
+
+ - Documented and extended the support for the `RSYNC_CONNECT_PROG` variable
+   that can be used to enhance the client side of a daemon connection.
+
+ - Improved the dashes and double-quotes in the nroff manpage output.
+
+ - Rsync now supports a lot more `--no-OPTION` override options.
+
+### INTERNAL:
+
+ - The file-list sorting algorithm now uses a sort that keeps any same-named
+   items in the same order as they were specified. This allows rsync to always
+   ensure that the first of the duplicates is the one that will be included in
+   the copy. The new sort is also faster than the glibc version of qsort() and
+   mergesort().
+
+ - Rsync now supports the transfer of 64-bit timestamps (`time_t` values).
+
+ - Made the file-deletion code use a little less stack when recursing through a
+   directory hierarchy of extraneous files.
+
+ - Fixed a build problem with older (2.x) versions of gcc.
+
+ - Added some isType() functions that make dealing with signed characters
+   easier without forcing variables via casts.
+
+ - Changed strcat/strcpy/sprintf function calls to use safer versions.
+
+ - Upgraded the included popt version to 1.10.2 and improved its use of
+   string-handling functions.
+
+ - Added missing prototypes for compatibility functions from the lib dir.
+
+ - Configure determines if iconv() has a const arg, allowing us to avoid a
+   compiler warning.
+
+ - Made the sending of some numbers more efficient for protocol 30.
+
+ - Make sure that a daemon process doesn't mind if the client was weird and
+   omitted the `--server` option.
+
+ - There are more internal logging categories available in protocol 30 than the
+   age-old FINFO and FERROR, including `FERROR_XFER` and FWARN. These new
+   categories allow some errors and warnings to go to stderr without causing an
+   erroneous end-of-run warning about some files not being able to be
+   transferred.
+
+ - Improved the use of `const` on pointers.
+
+ - Improved J.W.'s `pool_alloc` routines to add a way of incrementally freeing
+   older sections of a pool's memory.
+
+ - The getaddrinfo.c compatibility code in the `lib` dir was replaced with some
+   new code (derived from samba, derived from PostgreSQL) that has a better
+   license than the old code.
+
+### DEVELOPER RELATED:
+
+ - Rsync is now licensed under the GPLv3 or later.
+
+ - Rsync is now being maintained in a `git` repository instead of CVS (though
+   the old CVS repository still exists for historical access).  Several
+   maintenance scripts were updated to work with git.
+
+ - Generated files are no longer committed into the source repository. The
+   autoconf and autoheader commands are now automatically run during the normal
+   use of `configure` and `make`. The latest dev versions of all generated
+   files can also be copied from the samba.org web site (see the prepare-source
+   script's fetch option).
+
+ - The `patches` directory of diff files is now built from branches in the
+   rsync git repository (branch patch/FOO creates file patches/FOO.diff).  This
+   directory is now distributed in a separate separate tar file named
+   rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
+
+ - The proto.h file is now built using a simple perl script rather than a
+   complex awk script, which proved to be more widely compatible.
+
+ - When running the tests, we now put our per-test temp dirs into a sub-
+   directory named testtmp (which is created, if missing). This allows someone
+   to symlink the testtmp directory to another filesystem (which is useful if
+   the build dir's filesystem does not support ACLs and xattrs, but another
+   filesystem does).
+
+ - Rsync now has a way of handling protocol-version changes during the
+   development of a new protocol version. This causes any out-of-sync versions
+   to speak an older protocol rather than fail in a cryptic manner.  This
+   addition makes it safer to deploy a pre-release version that may interact
+   with the public. This new exchange of sub-version info does not interfere
+   with the `{MIN,MAX}_PROTOCOL_VERSION` checking algorithm (which does not
+   have enough range to allow the main protocol number to be incremented for
+   every minor tweak in that happens during development).
+
+ - The csprotocol.txt file was updated to mention the daemon protocol change in
+   the 3.0.0 release.

+
+# NEWS for rsync 2.6.9 (6 Nov 2006)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - If rsync is interrupted via a handled signal (such as SIGINT), it will once
+   again clean-up its temp file from the destination dir.
+
+ - Fixed an overzealous sanitizing bug in the handling of the `--link-dest`,
+   `--copy-dest`, and `--compare-dest` options to a daemon without chroot: if
+   the copy's destination dir is deeper than the top of the module's path,
+   these options now accept a safe number of parent-dir (../) references (since
+   these options are relative to the destination dir). The old code incorrectly
+   chopped off all `../` prefixes for these options, no matter how deep the
+   destination directory was in the module's hierarchy.
+
+ - Fixed a bug where a deferred info/error/log message could get sent directly
+   to the sender instead of being handled by rwrite() in the generator. This
+   fixes an `unexpected tag 3` fatal error, and should also fix a potential
+   problem where a deferred info/error message from the receiver might bypass
+   the log file and get sent only to the client process. (These problems could
+   only affect an rsync daemon that was receiving files.)
+
+ - Fixed a bug when `--inplace` was combined with a `--*-dest` option and we
+   update a file's data using an alternate basis file. The code now notices
+   that it needs to copy the matching data from the basis file instead of
+   (wrongly) assuming that it was already present in the file.
+
+ - Fixed a bug where using `--dry-run` with a `--*-dest` option with a path
+   relative to a directory that does not yet exist: the affected option gets
+   its proper path value so that the output of the dry-run is right.
+
+ - Fixed a bug in the %f logfile escape when receiving files: the destination
+   path is now included in the output (e.g. you can now tell when a user
+   specifies a subdir inside a module).
+
+ - If the receiving side fails to create a directory, it will now skip trying
+   to update everything that is inside that directory.
+
+ - If `--link-dest` is specified with `--checksum` but without `--times`, rsync
+   will now allow a hard-link to be created to a matching link-dest file even
+   when the file's modify-time doesn't match the server's file.
+
+ - The daemon now calls more timezone-using functions prior to doing a chroot.
+   This should help some C libraries to generate proper timestamps from inside
+   a chrooted daemon (and to not try to access /etc/timezone over and over
+   again).
+
+ - Fixed a bug in the handling of an absolute `--partial-dir=ABS_PATH` option:
+   it now deletes an alternate basis file from the partial-dir that was used to
+   successfully update a destination file.
+
+ - Fixed a bug in the handling of `--delete-excluded` when using a per-dir
+   merge file: the merge file is now honored on the receiving side, and only
+   its unqualified include/exclude commands are ignored (just as is done for
+   global include/excludes).
+
+ - Fixed a recent bug where `--delete` was not working when transferring from
+   the root (/) of the filesystem with `--relative` enabled.
+
+ - Fixed a recent bug where an `--exclude='*'` could affect the root (/) of the
+   filesystem with `--relative` enabled.
+
+ - When `--inplace` creates a file, it is now created with owner read/write
+   permissions (0600) instead of no permissions at all. This avoids a problem
+   continuing a transfer that was interrupted (since `--inplace` will not
+   update a file that has no write permissions).
+
+ - If either `--remove-source-files` or `--remove-sent-files` is enabled and we
+   are unable to remove the source file, rsync now outputs an error.
+
+ - Fixed a bug in the daemon's `incoming chmod` rule: newly-created directories
+   no longer get the 'F' (file) rules applied to them.
+
+ - Fixed an infinite loop bug when a filter rule was rejected due to being
+   overly long.
+
+ - When the server receives a `--partial-dir` option from the client, it no
+   longer runs the client-side code that adds an assumed filter rule (since the
+   client will be sending us the rules in the usual manner, and they may have
+   chosen to override the auto-added rule).
+
+### ENHANCEMENTS:
+
+ - Added the `--log-file=FILE` and `--log-file-format=FORMAT` options. These
+   can be used to tell any rsync to output what it is doing to a log file.
+   They work with a client rsync, a non-daemon server rsync (see the manpage
+   for instructions), and also allows the overriding of rsyncd.conf settings
+   when starting a daemon.
+
+ - The `--log-format` option was renamed to be `--out-format` to avoid
+   confusing it with affecting the log-file output. (The old option remains as
+   an alias for the new to preserve backward compatibility.)
+
+ - Made `log file` and `syslog facility` settable on a per-module basis in the
+   daemon's config file.
+
+ - Added the `--remove-source-files` option as a replacement for the (now
+   deprecated) `--remove-sent-files` option. This new option removes all
+   non-dirs from the source directories, even if the file was already
+   up-to-date. This fixes a problem where interrupting an rsync that was using
+   `--remove-sent-files` and restarting it could leave behind a file that the
+   earlier rsync synchronized, but didn't get to remove.  (The deprecated
+   `--remove-sent-files` is still understood for now, and still behaves in the
+   same way as before.)
+
+ - Added the option `--no-motd` to suppress the message-of-the-day output from
+   a daemon when doing a copy. (See the manpage for a caveat.)
+
+ - Added a new environment variable to the pre-/post-xfer exec commands (in the
+   daemon's config file): `RSYNC_PID`. This value will be the same in both the
+   pre- and post-xfer commands, so it can be used as a unique ID if the
+   pre-xfer command wants to cache some arg/request info for the post-xfer
+   command.
+
+### INTERNAL:
+
+ - Did a code audit using IBM's code-checker program and made several changes,
+   including: replacing most of the strcpy() and sprintf() calls with
+   strlcpy(), snprintf(), and memcpy(), adding a 0-value to an enum that had
+   been intermingling a literal 0 with the defined enum values, silencing some
+   uninitialized memory checks, marking some functions with a `noreturn`
+   attribute, and changing an `if` that could never succeed on some platforms
+   into a pre-processor directive that conditionally compiles the code.
+
+ - Fixed a potential bug in `f_name_cmp()` when both the args are a top-level
+   `.` dir (which doesn't happen in normal operations).
+
+ - Changed `exit_cleanup()` so that it can never return instead of exit.  The
+   old code might return if it found the `exit_cleanup()` function was being
+   called recursively. The new code is segmented so that any recursive calls
+   move on to the next step of the exit-processing.
+
+ - The macro WIFEXITED(stat) will now be defined if the OS didn't already
+   define it.
+
+### DEVELOPER RELATED:
+
+ - The acls.diff and xattrs.diff patches have received a bunch of work to make
+   them much closer to being acceptable in the main distribution.  The xattrs
+   patch also has some preliminary Mac OS X and FreeBSD compatibility code that
+   various system types to exchange extended file-attributes.
+
+ - A new diff in the patches dir, fake-root.diff, allows rsync to maintain a
+   backup hierarchy with full owner, group, and device info without actually
+   running as root. It does this using a special extended attribute, so it
+   depends on xattrs.diff (which depends on acls.diff).
+
+ - The rsync.yo and rsyncd.conf.yo files have been updated to work better with
+   the latest yodl 2.x releases.
+
+ - Updated config.guess and config.sub to their 2006-07-02 versions.
+
+ - Updated various files to include the latest FSF address and to have
+   consistent opening comments.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.6.8 (22 Apr 2006)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Fixed a bug in the exclude code where an anchored exclude without any
+   wildcards fails to match an absolute source arg, but only when `--relative`
+   is in effect.
+
+ - Improved the I/O code for the generator to fix a potential hang when the
+   receiver gets an EOF on the socket but the generator's select() call never
+   indicates that the socket is writable for it to be notified about the EOF.
+   (This can happen when using stunnel).
+
+ - Fixed a problem with the file-reading code where a failed read (such as that
+   caused by a bad sector) would not advance the file's read-position beyond
+   the failed read's data.
+
+ - Fixed a logging bug where the `log file` directive was not being honored in
+   a single-use daemon (one spawned by a remote-shell connection or by init).
+
+ - If rsync cannot honor the `--delete` option, we output an error and exit
+   instead of silently ignoring the option.
+
+ - Fixed a bug in the `--link-dest` code that prevented special files (such as
+   fifos) from being linked.
+
+ - The ability to hard-link symlinks and special files is now determined at
+   configure time instead of at runtime. This fixes a bug with `--link-dest`
+   creating a hard-link to a symlink's referent on a BSD system.
+
+### ENHANCEMENTS:
+
+ - In daemon mode, if rsync fails to bind to the requested port, the error(s)
+   returned by socket() and/or bind() are now logged.
+
+ - When we output a fatal error, we now output the version of rsync in the
+   message.
+
+ - Improved the documentation for the `--owner` and `--group` options.
+
+ - The rsyncstats script in `support` has an improved line-parsing regex that
+   is easier to read and also makes it to parse syslog-generated lines.
+
+ - A new script in `support`: file-attr-restore, can be used to restore the
+   attributes of a file-set (the permissions, ownership, and group info) taken
+   from the cached output of a `find ARG... -ls` command.
+
+### DEVELOPER RELATED:
+
+ - Removed the unused function `write_int_named()`, the unused variable
+   `io_read_phase`, and the rarely used variable `io_write_phase`. This also
+   elides the confusing 'phase "unknown"' part of one error message.
+
+ - Removed two unused configure checks and two related (also unused)
+   compatibility functions.
+
+ - The xattrs.diff patch received a security fix that prevents a potential
+   buffer overflow in the `receive_xattr()` code.
+
+ - The acls.diff patch has been improved quite a bit, with more to come.
+
+ - A new patch was added: log-file.diff. This contains an early version of a
+   future option, `--log-file=FILE`, that will allow any rsync to log its
+   actions to a file (something that only a daemon supports at present).
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.6.7 (11 Mar 2006)
+
+## Changes in this version:
+
+### OUTPUT CHANGES:
+
+ - The letter 'D' in the itemized output was being used for both devices
+   (character or block) as well as other special files (such as fifos and named
+   sockets). This has changed to separate non-device special files under the
+   'S' designation (e.g. `cS+++++++ path/fifo`). See also the `--specials`
+   option, below.
+
+ - The way rsync escapes unreadable characters has changed. First, rsync now
+   has support for recognizing valid multi-byte character sequences in your
+   current locale, allowing it to escape fewer characters than before for a
+   locale such as UTF-8. Second, it now uses an escape idiom of `\#123`, which
+   is the literal string `\#` followed by exactly 3 octal digits. Rsync no
+   longer doubles a backslash character in a filename (e.g. it used to output
+   `foo\\bar` when copying `foo\bar`) -- now it only escapes a backslash that
+   is followed by a hash-sign and 3 digits (0-9) (e.g. it will output
+   `foo\#134#789` when copying `foo\#789`). See also the `--8-bit-output`
+   (`-8`) option, mentioned below.
+
+   Script writers: the local rsync is the one that outputs escaped names, so if
+   you need to support unescaping of filenames for older rsyncs, I'd suggest
+   that you parse the output of `rsync --version` and only use the old
+   unescaping rules for 2.6.5 and 2.6.6.
+
+### BUG FIXES:
+
+ - Fixed a really old bug that caused `--checksum` (`-c`) to checksum all the
+   files encountered during the delete scan (ouch).
+
+ - Fixed a potential hang in a remote generator: when the receiver gets a
+   read-error on the socket, it now signals the generator about this so that
+   the generator does not try to send any of the terminating error messages to
+   the client (avoiding a potential hang in some setups).
+
+ - Made hard-links work with symlinks and devices again.
+
+ - If the sender gets an early EOF reading a source file, we propagate this
+   error to the receiver so that it can discard the file and try requesting it
+   again (which is the existing behavior for other kinds of read errors).
+
+ - If a device-file/special-file changes permissions, rsync now updates the
+   permissions without recreating the file.
+
+ - If the user specifies a remote-host for both the source and destination, we
+   now output a syntax error rather than trying to open the destination
+   hostspec as a filename.
+
+ - When `--inplace` creates a new destination file, rsync now creates it with
+   permissions 0600 instead of 0000 -- this makes restarting possible when the
+   transfer gets interrupted in the middle of sending a new file.
+
+ - Reject the combination of `--inplace` and `--sparse` since the sparse-output
+   algorithm doesn't work when overwriting existing data.
+
+ - Fixed the directory name in the error that is output when `pop_dir()` fails.
+
+ - Really fixed the parsing of a `!` entry in .cvsignore files this time.
+
+ - If the generator gets a stat() error on a file, output it (this used to
+   require at least `-vv` for the error to be seen).
+
+ - If waitpid() fails or the child rsync didn't exit cleanly, we now handle the
+   exit status properly and generate a better error.
+
+ - Fixed some glitches in the double-verbose output when using `--copy-dest`,
+   `--link-dest`, or `--compare-dest`. Also improved how the verbose output
+   handles hard-links (within the transfer) that had an up-to-date alternate
+   `dest` file, and copied files (via `--copy-dest`).
+
+ - Fixed the matching of the dont-compress items (e.g. `*.gz`) against files
+   that have a path component containing a slash.
+
+ - If the code reading a filter/exclude file gets an EINTR error, rsync now
+   clears the error flag on the file handle so it can keep on reading.
+
+ - If `--relative` is active, the sending side cleans up trailing `/` or `/.`
+   suffixes to avoid triggering a bug in older rsync versions. Also, we now
+   reject a `..` dir if it would be sent as a relative dir.
+
+ - If a non-directory is in the way of a directory and rsync is run with
+   `--dry-run` and `--delete`, rsync no longer complains about not being able
+   to opendir() the not-yet present directory.
+
+ - When `--list-only` is used and a non-existent local destination dir was also
+   specified as a destination, rsync no longer generates a warning about being
+   unable to create the missing directory.
+
+ - Fixed some problems with `--relative --no-implied-dirs` when the destination
+   directory did not yet exist: we can now create a symlink or device when it
+   is the first thing in the missing dir, and `--fuzzy` no longer complains
+   about being unable to open the missing dir.
+
+ - Fixed a bug where the `--copy-links` option would not affect implied
+   directories without `--copy-unsafe-links` (see `--relative`).
+
+ - Got rid of the need for `--force` to be used in some circumstances with
+   `--delete-after` (making it consistent with
+   `--delete-before`/`--delete-during`).
+
+ - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this when a
+   file is too large (rsync handles the write error).
+
+ - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it was
+   not properly padded with trailing '=' chars. This only affects a user that
+   need to use a password-authenticated proxy for an outgoing daemon-rsync
+   connection.
+
+ - If we're transferring an empty directory to a new name, rsync no longer
+   forces `S_IWUSR` if it wasn't already set, nor does it accidentally leave it
+   set.
+
+ - Fixed a bug in the debug output (`-vvvvv`) that could mention the wrong
+   checksum for the current file offset.
+
+ - Rsync no longer allows a single directory to be copied over a non-directory
+   destination arg.
+
+### ENHANCEMENTS:
+
+ - Added the `--append` option that makes rsync append data onto files that are
+   longer on the source than the destination (this includes new files).
+
+ - Added the `--min-size=SIZE` option to exclude small files from the transfer.
+
+ - Added the `--compress-level` option to allow you to set how aggressive
+   rsync's compression should be (this option implies `--compress`).
+
+ - Enhanced the parsing of the SIZE value for `--min-size` and `--max-size` to
+   allow easy entry of multiples of 1000 (instead of just multiples of 1024)
+   and off-by-one values too (e.g. `--max-size=8mb-1`).
+
+ - Added the `--8-bit-output` (`-8`) option, which tells rsync to avoid
+   escaping high-bit characters that it thinks are unreadable in the current
+   locale.
+
+ - The new option `--human-readable` (`-h`) changes the output of `--progress`,
+   `--stats`, and the end-of-run summary to be easier to read. If repeated, the
+   units become powers of 1024 instead of powers of 1000. (The old meaning of
+   `-h`, as a shorthand for `--help`, still works as long as you just use it on
+   its own, as in `rsync -h`.)
+
+ - If lutimes() and/or lchmod() are around, use them to allow the preservation
+   of attributes on symlinks.
+
+ - The `--link-dest` option now affects symlinks and devices (when possible).
+
+ - Added two config items to the rsyncd.conf parsing: `pre-xfer exec` and
+   `post-xfer exec`. These allow a command to be specified on a per-module
+   basis that will be run before and/or after a daemon-mode transfer. (See the
+   manpage for a list of the environment variables that are set with
+   information about the transfer.)
+
+ - When using the `--relative` option, you can now insert a dot dir in the
+   source path to indicate where the replication of the source dirs should
+   start. For example, if you specify a source path of
+   rsync://host/module/foo/bar/./baz/dir with `-R`, rsync will now only
+   replicate the `baz/dir` part of the source path (note: a trailing dot dir is
+   unaffected unless it also has a trailing slash).
+
+ - Added some new `--no-FOO` options that make it easier to override unwanted
+   implied or default options. For example, `-a --no-o` (aka `--archive
+   --no-owner`) can be used to turn off the preservation of file ownership that
+   is implied by `-a`.
+
+ - Added the `--chmod=MODE` option that allows the destination permissions to
+   be changed from the source permissions. E.g. `--chmod=g+w,o-rwx`
+
+ - Added the `incoming chmod` and `outgoing chmod` daemon options that allow a
+   module to specify what permissions changes should be applied to all files
+   copied to and from the daemon.
+
+ - Allow the `--temp-dir` option to be specified when starting a daemon, which
+   sets the default temporary directory for incoming files.
+
+ - If `--delete` is combined with `--dirs` without `--recursive`, rsync will
+   now delete in any directory whose content is being synchronized.
+
+ - If `--backup` is combined with `--delete` without `--backup-dir` (and
+   without `--delete-excluded`), we add a `protect` filter-rule to ensure that
+   files with the backup suffix are not deleted.
+
+ - The file-count stats that are output by `--progress` were improved to better
+   indicate what the numbers mean. For instance, the output: `(xfer#5,
+   to-check=8383/9999)` indicates that this was the fifth file to be
+   transferred, and we still need to check 8383 more files out of a total of
+   9999.
+
+ - The include/exclude code now allows a `dir/***` directive (with 3 trailing
+   stars) to match both the dir itself as well as all the content below the dir
+   (`dir/**` would not match the dir).
+
+ - Added the `--prune-empty-dirs` (`-m`) option that makes the receiving rsync
+   discard empty chains of directories from the file-list. This makes it easier
+   to selectively copy files from a source hierarchy and end up with just the
+   directories needed to hold the resulting files.
+
+ - If the `--itemize-changes` (`-i`) option is repeated, rsync now includes
+   unchanged files in the itemized output (similar to `-vv`, but without all
+   the other verbose messages that can get in the way). Of course, the client
+   must be version 2.6.7 for this to work, but the remote rsync only needs to
+   be 2.6.7 if you're pushing files.
+
+ - Added the `--specials` option to tell rsync to copy non-device special files
+   (which rsync now attempts even as a normal user). The `--devices` option now
+   requests the copying of just devices (character and block).  The `-D` option
+   still requests both (e.g. `--devices` and `--specials`), `-a` still implies
+   `-D`, and non-root users still get a silent downgrade that omits device
+   copying.
+
+ - Added the `--super` option to make the receiver always attempt super-user
+   activities. This is useful for systems that allow things such as devices to
+   be created or ownership to be set without being UID 0, and is also useful
+   for someone who wants to ensure that errors will be output if the receiving
+   rsync isn't being run as root.
+
+ - Added the `--sockopts` option for those few who want to customize the TCP
+   options used to contact a daemon rsync.
+
+ - Added a way for the `--temp-dir` option to be combined with a partial-dir
+   setting that lets rsync avoid non-atomic updates (for those times when
+   `--temp-dir` is not being used because space is tight).
+
+ - A new support script, files-to-excludes, will transform a list of files into
+   a set of include/exclude directives that will copy those files.
+
+ - A new option, `--executability` (`-E`) can be used to preserve just the
+   execute bit on files, for those times when using the `--perms` option is not
+   desired.
+
+ - The daemon now logs each connection and also each module-list request that
+   it receives.
+
+ - New log-format options: %M (modtime), %U (uid), %G (gid), and %B (permission
+   bits, e.g. `rwxr-xrwt`).
+
+ - The `--dry-run` option no longer forces the enabling of `--verbose`.
+
+ - The `--remove-sent-files` option now does a better job of incrementally
+   removing the sent files on the sending side (older versions tended to clump
+   up all the removals at the end).
+
+ - A daemon now supersedes its minimal SIGCHLD handler with the standard
+   PID-remembering version after forking. This ensures that the generator can
+   get the child-exit status from the receiver.
+
+ - Use of the `--bwlimit` option no longer interferes with the remote rsync
+   sending error messages about invalid/refused options.
+
+ - Rsync no longer returns a usage error when used with one local source arg
+   and no destination: this now implies the `--list-only` option, just like the
+   comparable situation with a remote source arg.
+
+ - Added the `--copy-dirlinks` option, a more limited version of
+   `--copy-links`.
+
+ - Various documentation improvements, including: a better synopsis, some
+   improved examples, a better discussion of the presence and absence of
+   `--perms` (including how it interacts with the new `--executability` and
+   `--chmod` options), an extended discussion of `--temp-dir`, an improved
+   discussion of `--partial-dir`, a better description of rsync's pattern
+   matching characters, an improved `--no-implied-dirs` section, and the
+   documenting of what the `--stats` option outputs.
+
+ - Various new and updated diffs in the patches dir, including: acls.diff,
+   xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
+
+### INTERNAL:
+
+ - We now use sigaction() and sigprocmask() if possible, and fall back on
+   signal() if not. Using sigprocmask() ensures that rsync enables all the
+   signals that it needs, just in case it was started in a masked state.
+
+ - Some buffer sizes were expanded a bit, particularly on systems where
+   MAXPATHLEN is overly small (e.g. Cygwin).
+
+ - If `io_printf()` tries to format more data than fits in the buffer, exit
+   with an error instead of transmitting a truncated buffer.
+
+ - If a `va_copy` macro is defined, lib/snprintf.c will use it when defining
+   the `VA_COPY` macro.
+
+ - Reduced the amount of stack memory needed for each level of directory
+   recursion by nearly MAXPATHLEN bytes.
+
+ - The wildmatch function was extended to allow an array of strings to be
+   supplied as the string to match. This allows the exclude code to do less
+   string copying.
+
+ - Got rid of the `safe_fname()` function (and all the myriad calls) and
+   replaced it with a new function in the log.c code that filters all the
+   output going to the terminal.
+
+ - Unified the `f_name()` and the `f_name_to()` functions.
+
+ - Improved the hash-table code the sender uses to handle checksums to make it
+   use slightly less memory and run just a little faster.
+
+### DEVELOPER RELATED:
+
+ - The diffs in the patches dir now require `patch -p1 <DIFF` instead of the
+   previous `-p0`. Also, the version included in the release tar now affect
+   generated files (e.g. configure, rsync.1, proto.h, etc.), so it is no longer
+   necessary to run autoconf and/or yodl unless you're applying a patch that
+   was checked out from CVS.
+
+ - Several diffs in the patches dir now use the proper `--enable-FOO` configure
+   option instead of `--with-FOO` to turn on the inclusion of the newly patched
+   feature.
+
+ - There is a new script, `prepare-source` than can be used to update the
+   various generated files (proto.h, configure, etc.) even before configure has
+   created the Makefile (this is mainly useful when patching the source with a
+   patch that doesn't affect generated files).
+
+ - The testsuite now sets HOME so that it won't be affected by a file such as
+   ~/.popt.

+
+# NEWS for rsync 2.6.6 (28 Jul 2005)
+
+## Changes in this version:
+
+### SECURITY FIXES:
+
+ - The zlib code was upgraded to version 1.2.3 in order to make it more secure.
+   While the widely-publicized security problem in zlib 1.2.2 did not affect
+   rsync, another security problem surfaced that affects rsync's zlib 1.1.4.
+
+### BUG FIXES:
+
+ - The setting of `flist->high` in `clean_flist()` was wrong for an empty list.
+   This could cause `flist_find()` to crash in certain rare circumstances (e.g.
+   if just the right directory setup was around when `--fuzzy` was combined
+   with `--link-dest`).
+
+ - The outputting of hard-linked files when verbosity was > 1 was not right:
+   (1) Without `-i` it would output the name of each hard-linked file as though
+   it had been changed; it now outputs a `is hard linked` message for the file.
+   (2) With `-i` it would output all dots for the unchanged attributes of a
+   hard-link; it now changes those dots to spaces, as is done for other totally
+   unchanged items.
+
+ - When backing up a changed symlink or device, get rid of any old backup item
+   so that we don't get an `already exists` error.
+
+ - A couple places that were comparing a local and a remote modification-time
+   were not honoring the `--modify-window` option.
+
+ - Fixed a bug where the 'p' (permissions) itemized-changes flag might get set
+   too often (if some non-significant mode bits differed).
+
+ - Fixed a really old, minor bug that could cause rsync to warn about being
+   unable to mkdir() a path that ends in `/.` because it just created the
+   directory (required `--relative`, `--no-implied-dirs`, a source path that
+   ended in either a trailing slash or a trailing `/.`, and a non-existing
+   destination dir to tickle the bug in a recent version).
+
+### ENHANCEMENTS:
+
+ - Made the `max verbosity` setting in the rsyncd.conf file settable on a
+   per-module basis (which now matches the documentation).
+
+ - The rrsync script has been upgraded to verify the args of options that take
+   args (instead of rejecting any such options). It was also changed to try to
+   be more secure and to fix a problem in the parsing of a pull operation that
+   has multiple source args. (See the support dir.)
+
+ - Improved the documentation that explains the difference between a normal
+   daemon transfer and a daemon-over remote-shell transfer.
+
+ - Some of the diffs supplied in the patches dir were fixed and/or improved.
+
+### BUILD CHANGES:
+
+ - Made configure define `NOBODY_USER` (currently hard-wired to `nobody`) and
+   `NOBODY_GROUP` (set to either `nobody` or `nogroup` depending on what we
+   find in the /etc/group file).
+
+ - Added a test to the test suite, itemized.test, that tests the output of `-i`
+   (log-format w/%i) and some double-verbose messages.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.6.5 (1 Jun 2005)
+
+## Changes in this version:
+
+### OUTPUT CHANGES:
+
+ - Non-printable chars in filenames are now output using backslash-escaped
+   characters rather than '?'s. Any non-printable character is output using 3
+   digits of octal (e.g. `\n` -> `\012`), and a backslash is now output as
+   `\\`. Rsync also uses your locale setting, which can make it treat fewer
+   high-bit characters as non-printable.
+
+ - If rsync received an empty file-list when pulling files, it would output a
+   `nothing to do` message and exit with a 0 (success) exit status, even if the
+   remote rsync returned an error (it did not do this under the same conditions
+   when pushing files). This was changed to make the pulling behavior the same
+   as the pushing behavior: we now do the normal end-of-run outputting
+   (depending on options) and exit with the appropriate exit status.
+
+### BUG FIXES:
+
+ - A crash bug was fixed when a daemon had its `path` set to `/`, did not have
+   chroot enabled, and used some anchored excludes in the rsyncd.conf file.
+
+ - Fixed a bug in the transfer of a single file when `-H` is specified (rsync
+   would either infinite loop or perhaps crash).
+
+ - Fixed a case where the generator might try (and fail) to tweak the
+   write-permissions of a read-only directory in list-only mode (this only
+   caused an annoying warning message).
+
+ - If `--compare-dest` or `--link-dest` uses a locally-copied file as the basis
+   for an updated version, log this better when `--verbose` or `-i` is in
+   effect.
+
+ - Fixed the accidental disabling of `--backup` during the `--delete-after`
+   processing.
+
+ - Restored the ability to use the `--address` option in client mode (in
+   addition to its use in daemon mode).
+
+ - Make sure that some temporary progress information from the delete
+   processing does not get left on the screen when it is followed by a newline.
+
+ - When `--existing` skips a directory with extra verbosity, refer to it as a
+   `directory`, not a `file`.
+
+ - When transferring a single file to a different-named file, any generator
+   messages that are source-file related no longer refer to the file by the
+   destination filename.
+
+ - Fixed a bug where hard-linking a group of files might fail if the generator
+   hasn't created a needed destination directory yet.
+
+ - Fixed a bug where a hard-linked group of files that is newly-linked to a
+   file in a `--link-dest` dir doesn't link the files from the rest of the
+   cluster.
+
+ - When deleting files with the `--one-file-system` (`-x`) option set, rsync no
+   longer tries to remove files from inside a mount-point on the receiving
+   side. Also, we don't complain about being unable to remove the mount-point
+   dir.
+
+ - Fixed a compatibility problem when using `--cvs-ignore` (`-C`) and sending
+   files to an older rsync without using `--delete`.
+
+ - Make sure that a `- !` or `+ !` include/exclude pattern does not trigger the
+   list-clearing action that is reserved for `!`.
+
+ - Avoid a timeout in the generator when the sender/receiver aren't handling
+   the generator's checksum output quickly enough.
+
+ - Fixed the omission of some directories in the delete processing when
+   `--relative` (`-R`) was combined with a source path that had a trailing
+   slash.
+
+ - Fixed a case where rsync would erroneously delete some files and then
+   re-transfer them when the options `--relative` (`-R`) and `--recursive`
+   (`-r`) were both enabled (along with `--delete`) and a source path had a
+   trailing slash.
+
+ - Make sure that `--max-size` doesn't affect a device or a symlink.
+
+ - Make sure that a system with a really small MAXPATHLEN does not cause the
+   buffers in `readfd_unbuffered()` to be too small to receive normal messages.
+   (This mainly affected Cygwin.)
+
+ - If a source pathname ends with a filename of `..`, treat it as if `../` had
+   been specified (so that we don't copy files to the parent dir of the
+   destination).
+
+ - If `--delete` is combined with a file-listing rsync command (i.e. no
+   transfer is happening), avoid outputting a warning that we couldn't delete
+   anything.
+
+ - If `--stats` is specified with `--delete-after`, ensure that all the
+   `deleting` messages are output before the statistics.
+
+ - Improved one `if` in the deletion code that was only checking errno for
+   ENOTEMPTY when it should have also been checking for EEXIST (for
+   compatibility with OS variations).
+
+### ENHANCEMENTS:
+
+ - Added the `--only-write-batch=FILE` option that may be used (instead of
+   `--write-batch=FILE`) to create a batch file without doing any actual
+   updating of the destination. This allows you to divert all the file-updating
+   data away from a slow data link (as long as you are pushing the data to the
+   remote server when creating the batch).
+
+ - When the generator is taking a long time to fill up its output buffer (e.g.
+   if the transferred files are few, small, or missing), it now periodically
+   flushes the output buffer so that the sender/receiver can get started on the
+   files sooner rather than later.
+
+ - Improved the keep-alive code to handle a long silence between the sender and
+   the receiver that can occur when the sender is receiving the checksum data
+   for a large file.
+
+ - Improved the auth-errors that are logged by the daemon to include some
+   information on why the authorization failed: wrong user, password mismatch,
+   etc. (The client-visible message is unchanged!)
+
+ - Improved the client's handling of an `@ERROR` from a daemon so that it does
+   not complain about an unexpectedly closed socket (since we really did expect
+   the socket to close).
+
+ - If the daemon can't open the log-file specified in rsyncd.conf, fall back to
+   using syslog and log an appropriate warning. This is better than what was
+   typically a totally silent (and fatal) failure (since a daemon is not
+   usually run with the `--no-detach` option that was necessary to see the
+   error on stderr).
+
+ - The manpages now consistently refer to an rsync daemon as a `daemon`
+   instead of a `server` (to distinguish it from the server process in a
+   non-daemon transfer).
+
+ - Made a small change to the rrsync script (restricted rsync -- in the support
+   dir) to make a read-only server reject all `--remove-*` options when sending
+   files (to future-proof it against the possibility of other similar options
+   being added at some point).
+
+### INTERNAL:
+
+ - Rsync now calls `setlocale(LC_CTYPE, "")`. This enables isprint() to better
+   discern which filename characters need to be escaped in messages (which
+   should result in fewer escaped characters in some locales).
+
+ - Improved the naming of the log-file open/reopen/close functions.
+
+ - Removed some protocol-compatibility code that was only needed to help
+   someone running a pre-release of 2.6.4.
+
+### BUILD CHANGES:
+
+ - Added configure option `--disable-locale` to disable any use of setlocale()
+   in the binary.
+
+ - Fixed a bug in the `SUPPORT{,_HARD}_LINKS` #defines which prevented rsync
+   from being built without symlink or hard-link support.
+
+ - Only #define `HAVE_REMSH` if it is going to be set to 1.
+
+ - Configure now disables the use of mkstemp() under HP-UX (since they refuse
+   to fix its broken handling of large files).
+
+ - Configure now explicitly checks for the lseek64() function so that the code
+   can use `HAVE_LSEEK64` instead of inferring lseek64()'s presence based on
+   the presence of the `off64_t` type.
+
+ - Configure no longer mentions the change in the default remote-shell (from
+   rsh to ssh) that occurred for the 2.6.0 release.
+
+ - Some minor enhancements to the test scripts.
+
+ - Added a few new `*.diff` files to the patches dir, including a patch that
+   enables the optional copying of extended attributes.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.6.4 (30 March 2005)
+
+## Changes in this version:
+
+### PROTOCOL NUMBER:
+
+ - The protocol number was changed to 29.
+
+### OUTPUT CHANGES:
+
+ - When rsync deletes a directory and outputs a verbose message about it, it
+   now appends a trailing slash to the name instead of (only sometimes)
+   outputting a preceding "directory " string.
+
+ - The `--stats` output will contain file-list time-statistics if both sides
+   are 2.6.4, or if the local side is 2.6.4 and the files are being pushed
+   (since the stats come from the sending side).  (Requires protocol 29 for a
+   pull.)
+
+ - The `%o` (operation) log-format escape now has a third value (besides `send`
+   and `recv`): `del.` (with trailing dot to make it 4 chars).  This changes
+   the way deletions are logged in the daemon's log file.
+
+ - When the `--log-format` option is combined with `--verbose`, rsync now
+   avoids outputting the name of the file twice in most circumstances.  As long
+   as the `--log-format` item does not refer to any post-transfer items (such
+   as %b or %c), the `--log-format` message is output prior to the transfer, so
+   `--verbose` is now the equivalent of a `--log-format` of '%n%L' (which
+   outputs the name and any link info). If the log output must occur after the
+   transfer to be complete, the only time the name is also output prior to the
+   transfer is when `--progress` was specified (so that the name will precede
+   the progress stats, and the full `--log-format` output will come after).
+
+ - Non-printable characters in filenames are replaced with a '?' to avoid
+   corrupting the screen or generating empty lines in the output.
+
+### BUG FIXES:
+
+ - Restore the list-clearing behavior of `!` in a .cvsignore file (2.6.3 was
+   only treating it as a special token in an rsync include/exclude file).
+
+ - The combination of `--verbose` and `--dry-run` now mentions the full list of
+   changes that would be output without `--dry-run`.
+
+ - Avoid a mkdir warning when removing a directory in the destination that
+   already exists in the `--backup-dir`.
+
+ - An OS that has a binary mode for its files (such as Cygwin) needed
+   `setmode(fd, O_BINARY)` called on the temp-file we opened with mkstemp().
+   (Fix derived from Cygwin's 2.6.3 rsync package.)
+
+ - Fixed a potential hang when verbosity is high, the client side is the
+   sender, and the file-list is large.
+
+ - Fixed a potential protocol-corrupting bug where the generator could merge a
+   message from the receiver into the middle of a multiplexed packet of data if
+   only part of that data had been written out to the socket when the message
+   from the generator arrived.
+
+ - We now check if the OS doesn't support using mknod() for creating FIFOs and
+   sockets, and compile-in some compatibility code using mkfifo() and socket()
+   when necessary.
+
+ - Fixed an off-by-one error in the handling of `--max-delete=N`. Also, if the
+   `--max-delete` limit is exceeded during a run, we now output a warning about
+   this at the end of the run and exit with a new error code (25).
+
+ - One place in the code wasn't checking if fork() failed.
+
+ - The `ignore nonreadable` daemon parameter used to erroneously affect
+   readable symlinks that pointed to a non-existent file.
+
+ - If the OS does not have lchown() and a chown() of a symlink will affect the
+   referent of a symlink (as it should), we no longer try to set the user and
+   group of a symlink.
+
+ - The generator now properly runs the hard-link loop and the dir-time
+   rewriting loop after we're sure that the redo phase is complete.
+
+ - When `--backup` was specified with `--partial-dir=DIR`, where DIR is a
+   relative path, the backup code was erroneously trying to backup a file that
+   was put into the partial-dir.
+
+ - If a file gets resent in a single transfer and the `--backup` option is
+   enabled along with `--inplace`, rsync no longer performs a duplicate backup
+   (it used to overwrite the first backup with the failed file).
+
+ - One call to `flush_write_file()` was not being checked for an error.
+
+ - The `--no-relative` option was not being sent from the client to a server
+   sender.
+
+ - If an rsync daemon specified `dont compress = ...` for a file and the client
+   tried to specify `--compress`, the libz code was not handling a compression
+   level of 0 properly. This could cause a transfer failure if the block-size
+   for a file was large enough (e.g. rsync might have exited with an error for
+   large files).
+
+ - Fixed a bug that would sometimes surface when using `--compress` and sending
+   a file with a block-size larger than 64K (either manually specified, or
+   computed due to the file being really large). Prior versions of rsync would
+   sometimes fail to decompress the data properly, and thus the transferred
+   file would fail its verification.
+
+ - If a daemon can't open the specified log file (i.e. syslog is not being
+   used), die without crashing. We also output an error about the failure on
+   stderr (which will only be seen if `--no-detach` was specified) and exit
+   with a new error code (6).
+
+ - A local transfer no longer duplicates all its include/exclude options (since
+   the forked process already has a copy of the exclude list, there's no need
+   to send them a set of duplicates).
+
+ - The output of the items that are being updated by the generator (dirs,
+   symlinks, devices) is now intermingled in the proper order with the output
+   from the items that the receiver is updating (regular files) when pulling.
+   This misordering was particularly bad when `--progress` was specified.
+   (Requires protocol 29.)
+
+ - When `--timeout` is specified, lulls that occur in the transfer while the
+   generator is doing work that does not generate socket traffic (looking for
+   changed files, deleting files, doing directory-time touch-ups, etc.) will
+   cause a new keep-alive packet to be sent that should keep the transfer going
+   as long as the generator continues to make progress. (Requires protocol 29.)
+
+ - The stat size of a device is not added to the total file size of the items
+   in the transfer (the size might be undefined on some OSes).
+
+ - Fixed a problem with refused-option messages sometimes not making it back to
+   the client side when a remote `--files-from` was in effect and the daemon
+   was the receiver.
+
+ - The `--compare-dest` option was not updating a file that differed in (the
+   preserved) attributes from the version in the compare-dest DIR.
+
+ - When rsync is copying files into a write-protected directory, fixed the
+   change-report output for the directory so that we don't report an identical
+   directory as changed.
+
+### ENHANCEMENTS:
+
+ - Rsync now supports popt's option aliases, which means that you can use
+   /etc/popt and/or ~/.popt to create your own option aliases.
+
+ - Added the `--delete-during` (`--del`) option which will delete files from
+   the receiving side incrementally as each directory in the transfer is being
+   processed. This makes it more efficient than the default,
+   before-the-transfer behavior, which is now also available as
+   `--delete-before` (and is still the default `--delete-WHEN` option that will
+   be chosen if `--delete` or `--delete-excluded` is specified without a
+   `--delete-WHEN` choice). All the `--del*` options infer `--delete`, so an
+   rsync daemon that refuses `delete` will still refuse to allow any
+   file-deleting options (including the new `--remove-sent-files` option).
+
+ - All the `--delete-WHEN` options are now more memory efficient: Previously an
+   duplicate set of file-list objects was created on the receiving side for the
+   entire destination hierarchy. The new algorithm only creates one directory
+   of objects at a time (for files inside the transfer).
+
+ - Added the `--copy-dest` option, which works like `--link-dest` except that
+   it locally copies identical files instead of hard-linking them.
+
+ - Added support for specifying multiple `--compare-dest`, `--copy-dest`, or
+   `--link-dest` options, but only of a single type. (Promoted from the patches
+   dir and enhanced.) (Requires protocol 29.)
+
+ - Added the `--max-size` option. (Promoted from the patches dir.)
+
+ - The daemon-mode options are now separated from the normal rsync options so
+   that they can't be mixed together. This makes it impossible to start a
+   daemon that has improper default option values (which could cause problems
+   when a client connects, such as hanging or crashing).
+
+ - The `--bwlimit` option may now be used in combination with `--daemon` to
+   specify both a default value for the daemon side and a value that cannot be
+   exceeded by a user-specified `--bwlimit` option.
+
+ - Added the `port` parameter to the rsyncd.conf file. (Promoted from the
+   patches dir.) Also added `address`. The command-line options take precedence
+   over a config-file option, as expected.
+
+ - In `_exit_cleanup()`: when we are exiting with a partially-received file, we
+   now flush any data in the write-cache before closing the partial file.
+
+ - The `--inplace` support was enhanced to work with `--compare-dest`,
+   `--link-dest`, and (the new) `--copy-dest` options. (Requires protocol 29.)
+
+ - Added the `--dirs` (`-d`) option for an easier way to copy directories
+   without recursion. Any directories that are encountered are created on the
+   destination. Specifying a directory with a trailing slash copies its
+   immediate contents to the destination.
+
+ - The `--files-from` option now implies `--dirs` (`-d`).
+
+ - Added the `--list-only` option, which is mainly a way for the client to put
+   the server into listing mode without needing to resort to any internal
+   option kluges (e.g. the age-old use of `-r --exclude='/*/*'` for a
+   non-recursive listing). This option is used automatically (behind the
+   scenes) when a modern rsync speaks to a modern daemon, but may also be
+   specified manually if you want to force the use of the `--list-only` option
+   over a remote-shell connection.
+
+ - Added the `--omit-dir-times` (`-O`) option, which will avoid updating the
+   modified time for directories when `--times` was specified. This option will
+   avoid an extra pass through the file-list at the end of the transfer (to
+   tweak all the directory times), which may provide an appreciable speedup for
+   a really large transfer. (Promoted from the patches dir.)
+
+ - Added the `--filter` (`-f`) option and its helper option, `-F`. Filter rules
+   are an extension to the existing include/exclude handling that also supports
+   nested filter files as well as per-directory filter files (like .cvsignore,
+   but with full filter-rule parsing).  This new option was chosen in order to
+   ensure that all existing include/exclude processing remained 100% compatible
+   with older versions. Protocol 29 is needed for full filter-rule support, but
+   backward-compatible rules work with earlier protocol versions.  (Promoted
+   from the patches dir and enhanced.)
+
+ - Added the `--delay-updates` option that puts all updated files into a
+   temporary directory (by default `.~tmp~`, but settable via the
+   `--partial-dir=DIR` option) until the end of the transfer. This makes the
+   updates a little more atomic for a large transfer.
+
+ - If rsync is put into the background, any output from `--progress` is
+   reduced.
+
+ - Documented the `max verbosity` setting for rsyncd.conf. (This setting was
+   added a couple releases ago, but left undocumented.)
+
+ - The sender and the generator now double-check the file-list index they are
+   given, and refuse to try to do a file transfer on a non-file index (since
+   that would indicate that something had gone very wrong).
+
+ - Added the `--itemize-changes` (`-i`) option, which is a way to output a more
+   detailed list of what files changed and in what way. The effect is the same
+   as specifying a `--log-format` of `%i %n%L` (see both the rsync and
+   rsyncd.conf manpages). Works with `--dry-run` too.
+
+ - Added the `--fuzzy` (`-y`) option, which attempts to find a basis file for a
+   file that is being created from scratch. The current algorithm only looks in
+   the destination directory for the created file, but it does attempt to find
+   a match based on size/mod-time (in case the file was renamed with no other
+   changes) as well as based on a fuzzy name-matching algorithm. This option
+   requires protocol 29 because it needs the new file-sorting order. (Promoted
+   from patches dir and enhanced.) (Requires protocol 29.)
+
+ - Added the `--remove-sent-files` option, which lets you move files between
+   systems.
+
+ - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal enclosed
+   in '[' and ']' (e.g. `[::1]`). (We already allowed IPv6 literals in the
+   rsync://HOST:PORT/PATH format.)
+
+ - When rsync recurses to build the file list, it no longer keeps open one or
+   more directory handles from the dir's parent dirs.
+
+ - When building under windows, the default for `--daemon` is now to avoid
+   detaching, requiring the new `--detach` option to force rsync to detach.
+
+ - The `--dry-run` option can now be combined with either `--write-batch` or
+   `--read-batch`, allowing you to run a do-nothing test command to see what
+   would happen without `--dry-run`.
+
+ - The daemon's `read only` config item now sets an internal `read_only`
+   variable that makes extra sure that no write/delete calls on the read-only
+   side can succeed.
+
+ - The log-format % escapes can now have a numeric field width in between the %
+   and the escape letter (e.g. `%-40n %08p`).
+
+ - Improved the option descriptions in the `--help` text.
+
+### SUPPORT FILES:
+
+ - Added atomic-rsync to the support dir: a perl script that will transfer some
+   files using rsync, and then move the updated files into place all at once at
+   the end of the transfer. Only works when pulling, and uses `--link-dest` and
+   a parallel hierarchy of files to effect its update.
+
+ - Added mnt-excl to the support dir: a perl script that takes the /proc/mounts
+   file and translates it into a set of excludes that will exclude all mount
+   points (even mapped mounts to the same disk). The excludes are made relative
+   to the specified source dir and properly anchored.
+
+ - Added savetransfer.c to the support dir: a C program that can make a copy of
+   all the data that flows over the wire. This lets you test for data
+   corruption (by saving the data on both the sending side and the receiving
+   side) and provides one way to debug a protocol error.
+
+ - Added rrsync to the support dir: this is an updated version of Joe Smith's
+   restricted rsync perl script. This helps to ensure that only certain rsync
+   commands can be run by an ssh invocation.
+
+### INTERNAL:
+
+ - Added better checking of the checksum-header values that come over the
+   socket.
+
+ - Merged a variety of file-deleting functions into a single function so that
+   it is easier to maintain.
+
+ - Improved the type of some variables (particularly blocksize vars) for
+   consistency and proper size.
+
+ - Got rid of the uint64 type (which we didn't need).
+
+ - Use a slightly more compatible set of core #include directives.
+
+ - Defined int32 in a way that ensures that the build dies if we can't find a
+   variable with at least 32 bits.
+
+### PROTOCOL DIFFERENCES FOR VERSION 29:
+
+ - A 16-bit flag-word is transmitted after every file-list index. This
+   indicates what is changing between the sender and the receiver. The
+   generator now transmits an index and a flag-word to indicate when dirs and
+   symlinks have changed (instead of producing a message), which makes the
+   outputting of the information more consistent and less prone to screen
+   corruption (because the local receiver/sender is now outputting all the
+   file-change info messages).
+
+ - If a file is being hard-linked, the `ITEM_XNAME_FOLLOWS` bit is enabled in
+   the flag-word and the name of the file that was linked immediately follows
+   in vstring format (see below).
+
+ - If a file is being transferred with an alternate-basis file, the
+   `ITEM_BASIS_TYPE_FOLLOWS` bit is enabled in the flag-word and a single byte
+   follows, indicating what type of basis file was chosen. If that indicates
+   that a fuzzy-match was selected, the `ITEM_XNAME_FOLLOWS` bit is set in the
+   flag-word and the name of the match in vstring format follows the basis
+   byte. A vstring is a variable length string that has its size written prior
+   to the string, and no terminating null.  If the string is from 1-127 bytes,
+   the length is a single byte. If it is from 128-32767 bytes, the length is
+   written as ((len >> 8) | 0x80) followed by (len % 0x100).
+
+ - The sending of exclude names is done using filter-rule syntax. This means
+   that all names have a prefixed rule indicator, even excludes (which used to
+   be sent as a bare pattern, when possible). The `-C` option will include the
+   per-dir .cvsignore merge file in the list of filter rules so it is
+   positioned correctly (unlike in some older transfer scenarios).
+
+ - Rsync sorts the filename list in a different way: it sorts the subdir names
+   after the non-subdir names for each dir's contents, and it always puts a
+   dir's contents immediately after the dir's name in the list. (Previously an
+   item named `foo.txt` would sort in between directory `foo/` and `foo/bar`.)
+
+ - When talking to a protocol 29 rsync daemon, a list-only request is able to
+   note this before the options are sent over the wire and the new
+   `--list-only` option is included in the options.
+
+ - When the `--stats` bytes are sent over the wire (or stored in a batch), they
+   now include two elapsed-time values: one for how long it took to build the
+   file-list, and one for how long it took to send it over the wire (each
+   expressed in thousandths of a second).
+
+ - When `--delete-excluded` is specified with some filter rules (AKA excludes),
+   a client sender will now initiate a send of the rules to the receiver (older
+   protocols used to omit the sending of excludes in this situation since there
+   were no receiver-specific rules that survived `--delete-excluded` back
+   then). Note that, as with all the filter-list sending, only items that are
+   significant to the other side will actually be sent over the wire, so the
+   filter-rule list that is sent in this scenario is often empty.
+
+ - An index equal to the file-list count is sent as a keep-alive packet from
+   the generator to the sender, which then forwards it on to the receiver. This
+   normally invalid index is only a valid keep-alive packet if the 16-bit
+   flag-word that follows it contains a single bit (`ITEM_IS_NEW`, which is
+   normally an illegal flag to appear alone).
+
+ - A protocol-29 batch file includes a bit for the setting of the `--dirs`
+   option and for the setting of the `--compress` option. Also, the shell
+   script created by `--write-batch` will use the `--filter` option instead of
+   `--exclude-from` to capture any filter rules.
+
+### BUILD CHANGES:
+
+ - Handle an operating system that use mkdev() in place of makedev().
+
+ - Improved configure to better handle cross-compiling.

+
+# NEWS for rsync 2.6.3 (30 Sep 2004)
+
+## Changes in this version:
+
+### SECURITY FIXES:
+
+ - A bug in the `sanitize_path` routine (which affects a non-chrooted rsync
+   daemon) could allow a user to craft a pathname that would get transformed
+   into an absolute path for certain options (but not for file-transfer names).
+   If you're running an rsync daemon with chroot disabled, **please upgrade**,
+   ESPECIALLY if the user privs you run rsync under is anything above `nobody`.
+
+   OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
+
+ - Please note that the 2-line footer (output when verbose) now uses the term
+   `sent` instead of `wrote` and `received` instead of `read`. If you are not
+   parsing the numeric values out of this footer, a script would be better off
+   using the empty line prior to the footer as the indicator that the verbose
+   output is over.
+
+ - The output from the `--stats` option was similarly affected to change
+   `written` to `sent` and `read` to `received`.
+
+ - Rsync ensures that a filename that contains a newline gets mentioned with
+   each newline transformed into a question mark (which prevents a filename
+   from causing an empty line to be output).
+
+ - The `backed up ...` message that is output when at least 2 `--verbose`
+   options are specified is now the same both with and without the
+   `--backup-dir` option.
+
+### BUG FIXES:
+
+ - Fixed a crash bug that might appear when `--delete` was used and multiple
+   source directories were specified.
+
+ - Fixed a 32-bit truncation of the file length when generating the checksums.
+
+ - The `--backup` code no longer attempts to create some directories over and
+   over again (generating warnings along the way).
+
+ - Fixed a bug in the reading of the secrets file (by the daemon) and the
+   password file (by the client): the files no longer need to be terminated by
+   a newline for their content to be read in.
+
+ - If a file has a read error on the sending side or the reconstructed data
+   doesn't match the expected checksum (perhaps due to the basis file changing
+   during the transfer), the receiver will no longer retain the resulting file
+   unless the `--partial` option was specified.  (Note: for the read-error
+   detection to work, neither side can be older than 2.6.3 -- older receivers
+   will always retain the file, and older senders don't tell the receiver that
+   the file had a read error.)
+
+ - If a file gets resent in a single transfer and the `--backup` option is
+   enabled, rsync no longer performs a duplicate backup (it used to overwrite
+   the original file in the backup area).
+
+ - Files specified in the daemon's `exclude` or `exclude from` config items are
+   now excluded from being uploaded (assuming that the module allows uploading
+   at all) in addition to the old download exclusion.
+
+ - Got rid of a potential hang in the receiver when near the end of a phase.
+
+ - When using `--backup` without a `--backup-dir`, rsync no longer preserves
+   the modify time on directories. This avoids confusing NFS.
+
+ - When `--copy-links` (`-L`) is specified, we now output a separate error for
+   a symlink that has no referent instead of claiming that a file `vanished`.
+
+ - The `--copy-links` (`-L`) option no longer has the side-effect of telling
+   the receiving side to follow symlinks. See the `--keep-dirlinks` option
+   (mentioned below) for a way to specify that behavior.
+
+ - Error messages from the daemon server's option-parsing (such as refused
+   options) are now successfully transferred back to the client (the server
+   used to fail to send the message because the socket wasn't in the right
+   state for the message to get through).
+
+ - Most transfer errors that occur during a daemon transfer are now returned to
+   the user in addition to being logged (some messages are intended to be
+   daemon-only and are not affected by this).
+
+ - Fixed a bug in the daemon authentication code when using one of the
+   batch-processing options.
+
+ - We try to work around some buggy IPv6 implementations that fail to implement
+   `IPV6_V6ONLY`. This should fix the `address in use` error that some daemons
+   get when running on an OS with a buggy IPv6 implementation. Also, if the new
+   code gets this error, we might suggest that the user specify `--ipv4` or
+   `--ipv6` (if we think it will help).
+
+ - When the remote rsync dies, make a better effort to recover any error
+   messages it may have sent before dying (the local rsync used to just die
+   with a socket-write error).
+
+ - When using `--delete` and a `--backup-dir` that contains files that are
+   hard-linked to their destination equivalents, rsync now makes sure that
+   removed files really get removed (avoids a really weird rename() behavior).
+
+ - Avoid a bogus run-time complaint about a lack of 64-bit integers when the
+   int64 type is defined as an `off_t` and it actually has 64-bits.
+
+ - Added a configure check for open64() without mkstemp64() so that we can
+   avoid using mkstemp() when such a combination is encountered.  This bypasses
+   a problem writing out large temp files on OSes such as AIX and HP-UX.
+
+ - Fixed an age-old crash problem with `--read-batch` on a local copy (rsync
+   was improperly assuming `--whole-file` for the local copy).
+
+ - When `--dry-run` (`-n`) is used and the destination directory does not
+   exist, rsync now produces a correct report of files that would be sent
+   instead of dying with a chdir() error.
+
+ - Fixed a bug that could cause a slow-to-connect rsync daemon to die with an
+   error instead of waiting for the connection to finish.
+
+ - Fixed an ssh interaction that could cause output to be lost when the user
+   chose to combine the output of rsync's stdout and stderr (e.g.  using the
+   `2>&1`).
+
+ - Fixed an option-parsing bug when `--files-from` got passed to a daemon.
+
+### ENHANCEMENTS:
+
+ - Added the `--partial-dir=DIR` option that lets you specify where to
+   (temporarily) put a partially transferred file (instead of overwriting the
+   destination file). E.g. `--partial-dir=.rsync-partial` Also added support
+   for the `RSYNC_PARTIAL_DIR` environment variable that, when found,
+   transforms a regular `--partial` option (such as the convenient `-P` option)
+   into one that also specifies a directory.
+
+ - Added `--keep-dirlinks` (`-K`), which allows you to symlink a directory onto
+   another partition on the receiving side and have rsync treat it as matching
+   a normal directory from the sender.
+
+ - Added the `--inplace` option that tells rsync to write each destination file
+   without using a temporary file. The matching of existing data in the
+   destination file can be severely limited by this, but there are also cases
+   where this is more efficient (such as appending data).  Use only when needed
+   (see the manpage for more details).
+
+ - Added the `write only` option for the daemon's config file.
+
+ - Added long-option names for `-4` and `-6` (namely `--ipv4` and `--ipv6`) and
+   documented all these options in the manpage.
+
+ - Improved the handling of the `--bwlimit` option so that it's less bursty,
+   more accurate, and works properly over a larger range of values.
+
+ - The rsync daemon-over-ssh code now looks for `SSH_CONNECTION` and
+   `SSH2_CLIENT` in addition to `SSH_CLIENT` to figure out the IP address.
+
+ - Added the `--checksum-seed=N` option for advanced users.
+
+ - Batch writing/reading has a brand-new implementation that is simpler, fixes
+   a few weird problems with the old code (such as no longer sprinkling the
+   batch files into different dirs or even onto different systems), and is much
+   less intrusive into the code (making it easier to maintain for the future).
+   The new code generates just one data file instead of three, which makes it
+   possible to read the batch on stdin via a remote shell. Also, the old
+   requirement of forcing the same fixed checksum-seed for all batch processing
+   has been removed.
+
+ - If an rsync daemon has a module set with `list = no` (which hides its
+   presence in the list of available modules), a user that fails to
+   authenticate gets the same `unknown module` error that they would get if the
+   module were actually unknown (while still logging the real error to the
+   daemon's log file). This prevents fishing for module names.
+
+ - The daemon's `refuse options` config item now allows you to match option
+   names using wildcards and/or the single-letter option names.
+
+ - Each transferred file now gets its permissions and modified-time updated
+   before the temp-file gets moved into place. Previously, the finished file
+   would have a very brief window where its permissions disallowed all group
+   and world access.
+
+ - Added the ability to parse a literal IPv6 address in an `rsync:` URL (e.g.
+   rsync://[2001:638:500:101::21]:873/module/dir).
+
+ - The daemon's wildcard expanding code can now handle more than 1000 filenames
+   (it's now limited by memory instead of having a hard-wired limit).
+
+### INTERNAL:
+
+ - Some cleanup in the exclude code has saved some per-exclude memory and made
+   the code easier to maintain.
+
+ - Improved the argv-overflow checking for a remote command that has a lot of
+   args.
+
+ - Use rsyserr() in the various places that were still calling rprintf() with
+   strerror() as an arg.
+
+ - If an rsync daemon is listening on multiple sockets (to handle both IPv4 and
+   IPv6 to a single port), we now close all the unneeded file handles after we
+   accept a connection (we used to close just one of them).
+
+ - Optimized the handling of larger block sizes (rsync used to slow to a crawl
+   if the block size got too large).
+
+ - Optimized away a loop in `hash_search()`.
+
+ - Some improvements to the `sanitize_path()` and `clean_fname()` functions
+   makes them more efficient and produce better results (while still being
+   compatible with the file-name cleaning that gets done on both sides when
+   sending the file-list).
+
+ - Got rid of `alloc_sanitize_path()` after adding a destination-buffer arg to
+   `sanitize_path()` made it possible to put all the former's functionality
+   into the latter.
+
+ - The file-list that is output when at least 4 verbose options are specified
+   reports the uid value on the sender even when rsync is not running as root
+   (since we might be sending to a root receiver).
+
+### BUILD CHANGES:
+
+ - Added a `gen` target to rebuild most of the generated files, including
+   configure, config.h.in, the manpages, and proto.h.
+
+ - If `make proto` doesn't find some changes in the prototypes, the proto.h
+   file is left untouched (its time-stamp used to always be updated).
+
+ - The variable `$STRIP` (that is optionally set by the install-strip target's
+   rule) was changed to `$INSTALL_STRIP` because some systems have `$STRIP`
+   already set in the environment.
+
+ - Fixed a build problem when `SUPPORT_HARD_LINKS` isn't defined.
+
+ - When cross-compiling, the gettimeofday() function is now assumed to be a
+   modern version that takes two-args (since we can't test it).
+
+### DEVELOPER RELATED:
+
+ - The scripts in the testsuite dir were cleaned up a bit and a few new tests
+   added.
+
+ - Some new diffs were added to the patches dir, and some accepted ones were
+   removed.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.6.2 (30 Apr 2004)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Fixed a major bug in the sorting of the filenames when `--relative` is used
+   for some sources (just sources such as `/` and `/*` were affected). This fix
+   ensures that we ask for the right file-list item when requesting changes
+   from the sender.
+
+ - Rsync now checks the return value of the close() function to better report
+   disk-full problems on an NFS file system.
+
+ - Restored the old daemon-server behavior of logging error messages rather
+   than returning them to the user. (A better long-term fix will be sought in
+   the future.)
+
+ - An obscure uninitialized-variable bug was fixed in the uid/gid code. (This
+   bug probably had no ill effects.)
+
+### BUILD CHANGES:
+
+ - Got rid of the configure check for sys/sysctl.h (it wasn't used and was
+   causing a problem on some systems). Also improved the
+   broken-largefile-locking test to try to avoid failure due to an NFS
+   build-dir.
+
+ - Fixed a compile problem on systems that don't define `AI_NUMERICHOST`.
+
+ - Fixed a compile problem in the popt source for compilers that don't support
+   `__attribute__`.
+
+### DEVELOPER RELATED:
+
+ - Improved the testsuite's `merge` test to work on OSF1.
+
+ - Two new diffs were added to the patches dir.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.6.1 (26 Apr 2004)
+
+## Changes in this version:
+
+### PROTOCOL NUMBER:
+
+ - The protocol number was changed to 28.
+
+### SECURITY FIXES:
+
+ - Paths sent to an rsync daemon are more thoroughly sanitized when chroot is
+   not used. If you're running a non-read-only rsync daemon with chroot
+   disabled, **please upgrade**, ESPECIALLY if the user privs you run rsync
+   under is anything above `nobody`.
+
+### ENHANCEMENTS:
+
+ - Lower memory use, more optimal transfer of data over the socket, and lower
+   CPU usage (see the INTERNAL section for details).
+
+ - The `RSYNC_PROXY` environment variable can now contain a `USER:PASS@` prefix
+   before the `HOST:PORT` information.  (Bardur Arantsson)
+
+ - The `--progress` output now mentions how far along in the transfer we are,
+   including both a count of files transferred and a percentage of the total
+   file-count that we've processed. It also shows better
+   current-rate-of-transfer and remaining-transfer-time values.
+
+ - Documentation changes now attempt to describe some often misunderstood
+   features more clearly.
+
+### BUG FIXES:
+
+ - When `-x` (`--one-file-system`) is combined with `-L` (`--copy-links`) or
+   `--copy-unsafe-links,` no symlinked files are skipped, even if the referent
+   file is on a different filesystem.
+
+ - The `--link-dest` code now works properly for a non-root user when (1) the
+   UIDs of the source and destination differ and `-o` was specified, or (2)
+   when the group of the source can't be used on the destination and `-g` was
+   specified.
+
+ - Fixed a bug in the handling of `-H` (hard-links) that might cause the
+   expanded PATH/NAME value of the current item to get overwritten (due to an
+   expanded-name caching bug).
+
+ - We now reset the `new data has been sent` flag at the start of each file we
+   send. This makes sure that an interrupted transfer with the `--partial`
+   option set doesn't keep a shorter temp file than the current basis file when
+   no new data has been transferred over the wire for that file.
+
+ - Fixed a byte-order problem in `--batch-mode` on big-endian machines.  (Jay
+   Fenlason)
+
+ - When using `--cvs-exclude`, the exclude items we get from a per-directory's
+   .cvsignore file once again only affect that one directory (not all following
+   directories too). The items are also now properly word-split and parsed
+   without any +/- prefix parsing.
+
+ - When specifying the USER@HOST: prefix for a file, the USER part can now
+   contain an '@', if needed (i.e. the last '@' is used to find the HOST, not
+   the first).
+
+ - Fixed some bugs in the handling of group IDs for non-root users: (1) It
+   properly handles a group that the sender didn't have a name for (it would
+   previously skip changing the group on any files in that group). (2) If
+   `--numeric-ids` is used, rsync no longer attempts to set groups that the
+   user doesn't have the permission to set.
+
+ - Fixed the `refuse options` setting in the rsyncd.conf file.
+
+ - Improved the `-x` (`--one-file-system`) flag's handling of any mount-point
+   directories we encounter. It is both more optimal (in that it no longer does
+   a useless scan of the contents of the mount-point dirs) and also fixes a
+   bug where a remapped mount of the original filesystem could get discovered
+   in a subdir we should be ignoring.
+
+ - Rsync no longer discards a double-slash at the start of a filename when
+   trying to open the file. It also no longer constructs names that start with
+   a double slash (unless the user supplied them).
+
+ - Path-specifying options to a daemon should now work the same with or without
+   chroot turned on. Previously, such a option (such as `--link-dest`) would
+   get its absolute path munged into a relative one if chroot was not on,
+   making that setting fairly useless.  Rsync now transforms the path into one
+   that is based on the module's base dir when chroot is not enabled.
+
+ - Fixed a compatibility problem interacting with older rsync versions that
+   might send us an empty `--suffix` value without telling us that
+   `--backup-dir` was specified.
+
+ - The `hosts allow` option for a daemon-over-remote-shell process now has
+   improved support for IPv6 addresses and a fix for systems that have a length
+   field in their socket structs.
+
+ - Fixed the ability to request an empty backup `--suffix` when sending files
+   to an rsync daemon.
+
+ - Fixed an option-parsing bug when `--files-from` was sent to a server sender.
+
+### INTERNAL:
+
+ - Most of the I/O is now buffered, which results in a pretty large speedup
+   when running under MS Windows. (Craig Barratt)
+
+ - Optimizations to the name-handling/comparing code have made some significant
+   reductions in user-CPU time for large file sets.
+
+ - Some cleanup of the variable types make the code more consistent.
+
+ - Reduced memory requirements of hard link preservation.  (J.W. Schultz)
+
+ - Implemented a new algorithm for hard-link handling that speeds up the code
+   significantly. (J.W. Schultz and Wayne Davison)
+
+ - The `--hard-link` option now uses the first existing file in the group of
+   linked files as the basis for the transfer. This prevents the sub-optimal
+   transfer of a file's data when a new hardlink is added on the sending side
+   and it sorts alphabetically earlier in the list than the files that are
+   already present on the receiving side.
+
+ - Dropped support for protocol versions less than 20 (2.3.0 released 15 Mar
+   1999) and activated warnings for protocols less than 25 (2.5.0 released 23
+   Aug 2001). (Wayne Davison and J.W. Schultz, severally)
+
+ - More optimal data transmission for `--hard-links` (protocol 28).
+
+ - More optimal data transmission for `--checksum` (protocol 28).
+
+ - Less memory is used when `--checksum` is specified.
+
+ - Less memory is used in the file list (a per-file savings).
+
+ - The generator is now better about not modifying the file list during the
+   transfer in order to avoid a copy-on-write memory bifurcation (on systems
+   where fork() uses shared memory).  Previously, rsync's shared memory would
+   slowly become unshared, resulting in real memory usage nearly doubling on
+   the receiving side by the end of the transfer. Now, as long as permissions
+   are being preserved, the shared memory should remain that way for the entire
+   transfer.
+
+ - Changed hardlink info and `file_struct` + strings to use allocation pools.
+   This reduces memory use for large file-sets and permits freeing memory to
+   the OS. (J.W. Schultz)
+
+ - The 2 pipes used between the receiver and generator processes (which are
+   forked on the same machine) were reduced to 1 pipe and the protocol improved
+   so that (1) it is now impossible to have the `redo` pipe fill up and hang
+   rsync, and (2) trailing messages from the receiver don't get lost on their
+   way through the generator over to the sender (which mainly affected
+   hard-link messages and verbose `--stats` output).
+
+ - Improved the internal uid/gid code to be more portable and a little more
+   optimized.
+
+ - The device numbers sent when using `--devices` are now sent as separate
+   major/minor values with 32-bit accuracy (protocol 28).  Previously, the
+   copied devices were sent as a single 32-bit number. This will make
+   inter-operation of 64-bit binaries more compatible with their 32-bit
+   brethren (with both ends of the connection are using protocol 28). Note that
+   optimizations in the binary protocol for sending the device numbers often
+   results in fewer bytes being used than before, even though more precision is
+   now available.
+
+ - Some cleanup of the exclude/include structures and its code made things
+   clearer (internally), simpler, and more efficient.
+
+ - The reading & writing of the file-list in batch-mode is now handled by the
+   same code that sends & receives the list over the wire. This makes it much
+   easier to maintain. (Note that the batch code is still considered to be
+   experimental.)
+
+### BUILD CHANGES:
+
+ - The configure script now accepts `--with-rsyncd-conf=PATH` to override the
+   default value of the /etc/rsyncd.conf file.
+
+ - Fixed configure bug when running `./configure --disable-ipv6`.
+
+ - Fixed compilation problem on Tru64 Unix (having to do with `sockaddr.sa_len`
+   and `sockaddr.sin_len`).
+
+### DEVELOPER RELATED:
+
+ - Fixed `make test` bug when build dir is not the source dir.
+
+ - Added a couple extra diffs in the `patches` dir, removed the ones that got
+   applied, and rebuilt the rest.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.6.0 (1 Jan 2004)
+
+## Changes in this version:
+
+### PROTOCOL NUMBER:
+
+ - The protocol number was changed to 27.  The maximum accepted protocol number
+   was increased from 30 to 40.
+
+### ENHANCEMENTS:
+
+ - `ssh` is now the default remote shell for rsync. If you want to change this,
+   configure like this: `./configure --with-rsh=rsh`.
+
+ - Added `--files-from`, `--no-relative`, `--no-implied-dirs`, and `--from0`.
+   Note that `--from0` affects the line-ending character for all the files read
+   by the `--*-from` options. (Wayne Davison)
+
+ - Length of csum2 is now per-file starting with protocol version
+   27. (J.W. Schultz)
+
+ - Per-file dynamic block size is now sqrt(file length). The per-file checksum
+   size is determined according to an algorithm provided by Donovan Baarda
+   which reduces the probability of rsync algorithm corrupting data and falling
+   back using the whole md4 checksums. (J.W. Schultz, Donovan Baarda)
+
+ - The `--stats` option no longer includes the (debug) malloc summary unless
+   the verbose option was specified at least twice.
+
+ - Added a new error/warning code for when files vanish from the sending side.
+   Made vanished source files not interfere with the file-deletion pass when
+   `--delete-after` was specified.
+
+ - Various trailing-info sections are now preceded by a newline.
+
+### BUG FIXES:
+
+ - Fixed several exclude/include matching bugs when using wild-cards.  This has
+   a several user-visible effects, all of which make the matching more
+   consistent and intuitive. This should hopefully not cause anyone problems
+   since it makes the matching work more like what people are expecting. (Wayne
+   Davison)
+
+ - A pattern with a `**` no longer causes a `*` to match slashes.  For example,
+   with `/*/foo/**`, `foo` must be 2 levels deep.  [If your string has BOTH `*`
+   and `**` wildcards, changing the `*` wildcards to `**` will provide the old
+   behavior in all versions.]
+
+ - `**/foo` now matches at the base of the transfer (like /foo does). [Use
+   `/**/foo` to get the old behavior in all versions.]
+
+ - A non-anchored wildcard term floats to match beyond the base of the
+   transfer. E.g. `CVS/R*` matches at the end of the path, just like the
+   non-wildcard term `CVS/Root` does. [Use `/CVS/R*` to get the old behavior in
+   all versions.]
+
+ - Including a `**` in the match term causes it to be matched against the
+   entire path, not just the name portion, even if there aren't any interior
+   slashes in the term. E.g. `foo**bar` would exclude `/path/foo-bar` (just
+   like before) as well as `/foo-path/baz-bar` (unlike before). [Use `foo*bar`
+   to get the old behavior in all versions.]
+
+ - The exclude list specified in the daemon's config file is now properly
+   applied to the pulled items no matter how deep the user's file-args are in
+   the source tree. (Wayne Davison)
+
+ - For protocol version >= 27, `mdfour_tail()` is called when the block size
+   (including `checksum_seed`) is a multiple of 64.  Previously it was not
+   called, giving the wrong MD4 checksum.  (Craig Barratt)
+
+ - For protocol version >= 27, a 64 bit bit counter is used in mdfour.c as
+   required by the RFC. Previously only a 32 bit bit counter was used, causing
+   incorrect MD4 file checksums for file sizes >= 512MB - 4. (Craig Barratt)
+
+ - Fixed a crash bug when interacting with older rsync versions and multiple
+   files of the same name are destined for the same dir.  (Wayne Davison)
+
+ - Keep tmp names from overflowing MAXPATHLEN.
+
+ - Make `--link-dest` honor the absence of `-p`, `-o`, and `-g`.
+
+ - Made rsync treat a trailing slash in the destination in a more consistent
+   manner.
+
+ - Fixed file I/O error detection. (John Van Essen)
+
+ - Fixed bogus `malformed address {hostname}` message in rsyncd log when
+   checking IP address against hostnames from `hosts allow` and `hosts deny`
+   parameters in config file.
+
+ - Print heap statistics when verbose >= 2 instead of when >= 1.
+
+ - Fixed a compression (`-z`) bug when syncing a mostly-matching file that
+   contains already-compressed data. (Yasuoka Masahiko and Wayne Davison)
+
+ - Fixed a bug in the `--backup` code that could cause deleted files to not get
+   backed up.
+
+ - When the backup code makes new directories, create them with mode 0700
+   instead of 0755 (since the directory permissions in the backup tree are not
+   yet copied from the main tree).
+
+ - Call setgroups() in a more portable manner.
+
+ - Improved file-related error messages to better indicate exactly what
+   pathname failed. (Wayne Davison)
+
+ - Fixed some bugs in the handling of `--delete` and `--exclude` when using the
+   `--relative` (`-R`) option. (Wayne Davison)
+
+ - Fixed bug that prevented regular files from replacing special files and
+   caused a directory in `--link-dest` or `--compare-dest` to block the
+   creation of a file with the same path. A directory still cannot be replaced
+   by a regular file unless `--delete` specified. (J.W. Schultz)
+
+ - Detect and report when open or opendir succeed but read and readdir fail
+   caused by network filesystem issues and truncated files. (David Norwood,
+   Michael Brown, J.W. Schultz)
+
+ - Added a fix that should give ssh time to restore the tty settings if the
+   user presses Ctrl-C at an ssh password prompt.
+
+### INTERNAL:
+
+ - Eliminated vestigial support for old versions that we stopped supporting.
+   (J.W. Schultz)
+
+ - Simplified some of the option-parsing code. (Wayne Davison)
+
+ - Some cleanup made to the exclude code, as well as some new defines added to
+   enhance readability. (Wayne Davison)
+
+ - Changed the protocol-version code so that it can interact at a lower
+   protocol level than the maximum supported by both sides.  Added an
+   undocumented option, `--protocol=N`, to force the value we advertise to the
+   other side (primarily for testing purposes).  (Wayne Davison)

+
+# NEWS for rsync 2.5.7 (4 Dec 2003)
+
+## Changes in this version:
+
+### SECURITY FIXES:
+
+ - Fix buffer handling bugs. (Andrew Tridgell, Martin Pool, Paul Russell,
+   Andrea Barisani)
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.5.6, aka "the dwd-between-jobs release" (26 Jan 2003)
+
+## Changes in this version:
+
+### ENHANCEMENTS:
+
+ - The `--delete-after` option now implies `--delete`. (Wayne Davison)
+
+ - The `--suffix` option can now be used with `--backup-dir`. (Michael
+   Zimmerman)
+
+ - Combining `::` syntax with the `--rsh`/`-e` option now uses the specified
+   remote-shell as a transport to talk to a (newly-spawned) server-daemon. This
+   allows someone to use daemon features, such as modules, over a secure
+   protocol, such as ssh. (JD Paul)
+
+ - The rsync:// syntax for daemon connections is now accepted in the
+   destination field.
+
+ - If the file name given to `--include-from` or `--exclude-from` is `-`, rsync
+   will read from standard input. (J.W. Schultz)
+
+ - New option `--link-dest` which is like `--compare-dest` except that
+   unchanged files are hard-linked in to the destination directory.  (J.W.
+   Schultz)
+
+ - Don't report an error if an excluded file disappears during an rsync run.
+   (Eugene Chupriyanov and Bo Kersey)
+
+ - Added .svn to `--cvs-exclude` list to support subversion. (Jon Middleton)
+
+ - Properly support IPv6 addresses in the rsyncd.conf `hosts allow` and `hosts
+   deny` fields. (Hideaki Yoshifuji)
+
+ - Changed exclude file handling to permit DOS or MAC style line terminations.
+   (J.W. Schultz)
+
+ - Ignore errors from chmod when `-p`/`-a`/`--preserve-perms` is not set.
+   (Dave Dykstra)
+
+### BUG FIXES:
+
+ - Fix `forward name lookup failed` errors on AIX 4.3.3. (John L. Allen, Martin
+   Pool)
+
+ - Generate each file's rolling-checksum data as we send it, not in a separate
+   (memory-eating) pass before hand. This prevents timeout errors on really
+   large files. (Stefan Nehlsen)
+
+ - Fix compilation on Tru64. (Albert Chin, Zoong Pham)
+
+ - Better handling of some client-server errors. (Martin Pool)
+
+ - Fixed a crash that would occur when sending a list of files that contains a
+   duplicate name (if it sorts to the end of the file list) and using
+   `--delete`. (Wayne Davison)
+
+ - Fixed the file-name duplicate-removal code when dealing with multiple dups
+   in a row. (Wayne Davison)
+
+ - Fixed a bug that caused rsync to lose the exit status of its child processes
+   and sometimes return an exit code of 0 instead of showing an error. (David
+   R. Staples, Dave Dykstra)
+
+ - Fixed bug in `--copy-unsafe-links` that caused it to be completely broken.
+   (Dave Dykstra)
+
+ - Prevent infinite recursion in cleanup code under certain circumstances.
+   (Sviatoslav Sviridov and Marc Espie)
+
+ - Fixed a bug that prevented rsync from creating intervening directories when
+   `--relative-paths`/`-R` is set. (Craig Barratt)
+
+ - Prevent `Connection reset by peer` messages from Cygwin. (Randy O'Meara)
+
+### INTERNAL:
+
+ - Many code cleanups and improved internal documentation. (Martin Pool, Nelson
+   Beebe)
+
+ - Portability fixes. (Dave Dykstra and Wayne Davison)
+
+ - More test cases. (Martin Pool)
+
+ - Some test-case fixes. (Brian Poole, Wayne Davison)
+
+ - Updated included popt to the latest vendor drop, version 1.6.4.  (Jos
+   Backus)
+
+ - Updated config.guess and config.sub to latest versions; this means rsync
+   should build on more platforms. (Paul Green)
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.5.5, aka Snowy River (2 Apr 2002)
+
+## Changes in this version:
+
+### ENHANCEMENTS:
+
+ - With `--progress`, when a transfer is complete show the time taken;
+   otherwise show expected time to complete. (Cameron Simpson)
+
+ - Make `make install-strip` works properly, and `make install` accepts a
+   DESTDIR variable for help in building binary packages.  (Peter
+   Breitenlohner, Greg Louis)
+
+ - If configured with `--enable-maintainer-mode`, then on receipt of a fatal
+   signal rsync will try to open an xterm running gdb, similarly to Samba's
+   `panic action` or GNOME's bug-buddy.  (Martin Pool)
+
+### BUG FIXES:
+
+ - Fix situation where failure to fork (e.g. because out of process slots)
+   would cause rsync to kill all processes owned by the current user. Yes,
+   really! (Paul Haas, Martin Pool)
+
+ - Fix test suite on Solaris. (Jos Backus, Martin Pool)
+
+ - Fix minor memory leak in socket code. (Dave Dykstra, Martin Pool.)
+
+ - Fix `--whole-file` problem that caused it to be the default even for remote
+   connections. (Martin Pool, Frank Schulz)
+
+ - Work around bug in Mac OS X mkdir(2), which cannot handle trailing slashes.
+   <http://www.opensource.apple.com/bugs/X/BSD%20Kernel/2734739.html> (Martin
+   Pool)
+
+ - Improved network error handling. (Greg A. Woods)
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.5.4, aka "Imitation lizard skin" (13 Mar 2002)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Additional fix for zlib double-free bug. (Martin Pool, Andrew Tridgell) (CVE
+   CAN-2002-0059)
+
+### ENHANCEMENTS:
+
+ - Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus) (Note that
+   rsync still uses a custom version of zlib; you can not just link against a
+   system library. See zlib/README.rsync)
+
+ - Additional test cases for `--compress`. (Martin Pool)
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.5.3, aka "Happy 26" (11 Mar 2002)
+
+## Changes in this version:
+
+### SECURITY FIXES:
+
+ - Make sure that supplementary groups are removed from a server
+   process after changing uid and gid. (Ethan Benson) (Debian bug
+   #132272, CVE CAN-2002-0080)
+
+### BUG FIXES:
+
+ - Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE CAN-2002-0059)
+
+ - Fixed problem that in many cases caused the error message unexpected read
+   size of 0 in `map_ptr` and resulted in the wrong data being copied.
+
+ - Fixed compilation errors on some systems caused by the use of `unsigned
+   int64` in rsync.h.
+
+ - Fixed problem on systems such as Sunos4 that do not support realloc on a
+   NULL pointer; error was 'out of memory in "flist_expand"'.
+
+ - Fix for rsync server processes hanging around after the client unexpectedly
+   disconnects. (Colin Walters) (Debian bug #128632)
+
+ - Cope with BSD systems on which mkdir() will not accept a trailing slash.
+
+### ENHANCEMENTS:
+
+ - Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that rsync still uses
+   a custom version of zlib; you can not just link against a system library.
+   See zlib/README.rsync)
+
+ - Command to initiate connections is only shown with `-vv`, rather than `-v`
+   as in 2.5.2. Output from plain `-v` is more similar to what was historically
+   used so as not to break scripts that try to parse the output.
+
+ - Added `--no-whole-file` and `--no-blocking-io` options (Dave Dykstra)
+
+ - Made the `--write-batch` and `--read-batch` options actually work and added
+   documentation in the manpage (Jos Backus)
+
+ - If the daemon is unable to fork a child to accept a connection, print an
+   error message. (Colin Walters)
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.5.2 (26 Jan 2002)
+
+## Changes in this version:
+
+### SECURITY FIXES:
+
+ - Signedness security patch from Sebastian Krahmer <krahmer@suse.de> -- in
+   some cases we were not sufficiently careful about reading integers from the
+   network.
+
+### PROTOCOL NUMBER:
+
+ - The protocol number was changed to 26.
+
+### BUG FIXES:
+
+ - Fix possible string mangling in log files.
+
+ - Fix for setting local address of outgoing sockets.
+
+ - Better handling of hardlinks and devices on platforms with 64-bit `dev_t` or
+   `ino_t`.
+
+ - Name resolution on machines supporting IPv6 is improved.
+
+ - Fix for device nodes. (dann frazier) (Debian #129135)
+
+### ENHANCEMENTS:
+
+ - With `-v`, rsync now shows the command used to initiate an ssh/rsh
+   connection.
+
+ - `--statistics` now shows memory heap usage on platforms that support
+   mallinfo().
+
+ - "The Ted T'so school of program optimization": make progress visible and
+   people will think it's faster. (With `--progress`, rsync will show you how
+   many files it has seen as it builds the `file_list`, giving some indication
+   that it has not hung.)
+
+ - Improvements to batch mode support. This is still experimental but testing
+   would be welcome. (Jos Backus)
+
+ - New `--ignore-existing` option, patch previously distributed with Vipul's
+   Razor. (Debian #124286)
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.5.1 (3 Jan 2002)
+
+## Changes in this version:
+
+### BUG FIXES:
+
+ - Fix for segfault in `--daemon` mode configuration parser. (Paul Mackerras)
+
+ - Correct `string<->address` parsing for both IPv4 and 6.  (YOSHIFUJI Hideaki,
+   SUMIKAWA Munechika and Jun-ichiro `itojun` Hagino)
+
+ - Various fixes for IPv6 support. (Dave Dykstra)
+
+ - rsync.1 typo fix. (Matt Kraai)
+
+ - Test suite typo fixes. (Tom Schmidt)
+
+ - rsync.1 grammar and clarity improvements. (Edward Welbourne)
+
+ - Correction to ./configure tests for `inet_ntop`. (Jeff Garzik)
+
+### ENHANCEMENTS:
+
+ - `--progress` and `-P` now show estimated data transfer rate (in a multiple
+   of bytes/s) and estimated time to completion. (Rik Faith)
+
+ - `--no-detach` option, required to run as a W32 service and also useful when
+   running on Unix under daemontools, AIX's SRC, or a debugger. (Max Bowsher,
+   Jos Backus)
+
+ - Clearer error messages for some conditions.
+
+------------------------------------------------------------------------------
+
+# NEWS for rsync 2.5.0 (30 Nov 2001)
+
+## Changes in this version:
+
+### PROTOCOL NUMBER:
+
+ - The protocol number was changed to 25.
+
+### ANNOUNCEMENTS:
+
+ - Martin Pool <mbp@samba.org> is now a co-maintainer.
+
+### NEW FEATURES:
+
+ - Support for LSB-compliant packaging <http://www.linuxbase.org/>
+
+ - Shell wildcards are allowed in `auth users` lines.
+
+ - Merged UNC rsync+ patch to support creation of standalone patch sets. By
+   Bert J. Dempsey and Debra Weiss, updated by Jos Backus.
+   <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
+
+ - IPv6 support based on a patch from KAME.net, on systems including modern
+   versions of Linux, Solaris, and HP-UX. Also includes IPv6 compatibility
+   functions for old OSs by the Internet Software Consortium, Paul Vixie, the
+   OpenSSH portability project, and OpenBSD.
+
+### ENHANCEMENTS:
+
+ - Include/exclude cluestick: with `-vv`, print out whether files are included
+   or excluded and why.
+
+ - Many error messages have more friendly explanations and more details.
+
+ - Manual page improvements plus scanty protocol documentation.
+
+ - When running as `--daemon` in the background and using a `log file`
+   rsyncd.conf directive, close the log file every time it is open when going
+   to sleep on the socket. This allows the log file to get cleaned out by
+   another process.
+
+ - Change to using libpopt rather than getopt for processing options. This
+   makes the code cleaner and the behaviour more consistent across platforms.
+   popt is included and built if not installed on the platform.
+
+ - More details in `--version`, including note about whether 64-bit files,
+   symlinks and hardlinks are supported.
+
+ - MD4 code may use less CPU cycles.
+
+ - Use mkstemp on systems where it is secure. If we use mktemp, explain that we
+   do it in a secure way.
+
+ - `--whole-file` is the default when source and target are on the local
+   machine.
+
+### BUG FIXES:
+
+ - Fix for various bugs causing rsync to hang.
+
+ - Attempt to fix Large File Summit support on AIX.
+
+ - Attempt to fix error handling lockup bug.
+
+ - Give a non-0 exit code if **any** of the files we have been asked to
+   transfer fail to transfer.
+
+ - For log messages containing ridiculously long strings that might overflow a
+   buffer rsync no longer aborts, but rather prints an ellipsis at the end of
+   the string. (Patch from Ed Santiago.)
+
+### PLATFORMS:
+
+ - Improved support for UNICOS (tested on Cray T3E and Cray SV1)
+
+ - autoconf2.52 (or later) is now required to rebuild the autoconf scripts. It
+   is not required to simply build rsync.
