(Addresses Debian bug #193773) + +Fixed a bug in resize2fs which caused it to fail on filesystems with a +non-empty bad block list. Resize2fs now discards any blocks on the +badblock list which are no longer part of the filesystem as the result +of a filesystem shrink. (Note: this means that shrinking and then +enlarging a filesystem is no longer a reversible operation; +information about bad blocks in the part of the filesystem which is to +be chopped off will be lost.) + +Changed resize2fs so the user can use prefixes to specify the units of +the new filesystem size (sectors, kilobytes, megabytes, or gigabytes), +and to make the error and informational messages explicitly display +the blocksize used by the filesystem, in order to avoid confusion. +(Addresses Debian bug: #189814) + +Added a new debugfs command, dump_unused, which dumps the contents of +all unused blocks to stdout. (Useful as an emergency try-to-find +deleted data command.) + +Added a new debugfs command, imap, which prints the location of a +specified inode in the inode table. + +Fixed a bug in the badblocks program which caused it to use one bit of +randomness in its non-destructive read/write test, instead of using a +full 8 bits of randomness. + +Added a new option (-t) to badblocks, which allows the user to control +the test pattern(s) used when checking a disk. + +The blkid probe function now more correctly detects UDF filesystems. + +Fixed a bug in the blkid library which caused it to not update its +cache if a filesystem changes from having a label to not having a +label. + +Fixed a bug in the blkid library which could avoid an infinite loop +in blkid_find_dev_with_tag() if /proc is not mounted and there the +/etc/blkid.tab file has not yet been created. + +Fixed the badblocks program so that the destructive read/write test +honors the -c option, and to use O_DIRECT when possible to avoid +thrashing the system block buffer cache. + +Fixed various NLS issues. + - Added Czech and Swedish translations + - Removed testing NYC translation + - Fixed NLS support for message abbreviations in e2fsck + - Remove de-utf.po, since we shouldn't have two versions using different + charset encodings. + - Used ngettext() (abbreviated with the macro P_(str1, str2, n)) to + simplify the statistics reporting in e2fsck. + +Changed configure.in so that its defaults for *BSD systems no longer +build an fsck wrapper, and not to install in /usr/local by default. + +Fixed some minor spelling errors/typo's in e2fsck and the configure +script. + +Fixed various Debian packaging issues (see debian/changelog). + +Updated and clarified man pages. (Addresses Debian Bug #195616) + +Programmer's notes: +------------------- + +Fix gcc -Wall nitpicks. + +Updated gettext implementation used by e2fsprogs to 0.11.5, and enable +NLS support by default. (Added partial workaround for gettext/Darwin +incompatibility problems.) + +Added full MIT KRB5 and Himdall compatibility support to the com_err +library and the compile_et program. (Addresses Debian bug #191900) + +Added the blkid_known_fstype() function to the blkid library, which +returns true if it is passed a filesystem type which is recognized by +the blkid probing functions. + +Improved the documentation for the blkid library. + +Added the ext2fs_get_device_sectsize() function the the ext2fs library, which +returns the hardware sector size of a device, if it is available. + +Added a dependency in the blkid library's .so file to the uuid +library, since the former uses the latter. (Addresses Debian bug +#194094) + +Added --with-diet-libc and --disable-evms to the configure script. + +Fixed a minor memory leak in the badblocks program. + +Fixed a portability problem in tune2fs --- not all systems have strptime(). + +Fixed a portability problem in debugfs with the use of getopt() more +than once. Old-style BSD, new-style BSD, and Linux C libraries all do +things differently. + +Add support Windows support to ext2fs_get_device_size(). + +Added (normally disabled) debugging code to the Unix I/O manager which +causes it to disable all userspace caching if the NO_IO_CACHE is +defined. + +Changed the test I/O manager so it can always be linked into e2fsck, +mke2fs, and tune2fs if enabled via --enable-test-io-debug to the +configure script. The test I/O manager will only print any debugging +information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment +variables are set, which specifies which I/O operations are logged and +a block number to watch, respectively. The log messages are sent to +stderr by default, unless a filename is specified via the +TEST_IO_LOGFILE environment variable. + |
