GNU Wget NEWS -- history of user-visible changes. * Noteworthy changes in release 1.24.5 (2024-03-10) [stable] ** Fix how subdomain matches are checked for HSTS. Fixes a minor issue where cookies may be leaked to the wrong domain ** Wget will now also parse the srcset attribute in HTML tags ** Support reading fetchmail style "user" and "passwd" fields from netrc ** In some cases, prevent the confusing "Cannot write to... (success)" error messages ** Support extremely fast download speeds (TB/s). Previously this would cause Wget to crash when printing the speed ** Improve portability on OpenBSD to run the test suite ** Ensure that CSS URLs are corectly quoted (Bug: 64082) * Noteworthy changes in release 1.21.4 (2023-05-11) ** Document --retry-on-host-error in help text ** Increase read buffer size to 64k. This should speed up downloads on gigabit and faster connections ** Update deprecated option '--html-extension' to '--adjust-extension' in documentation ** Update gnulib compatibility layer. Fixes HSTS test failures on i686. (Thanks to Andreas Enge for ponting it out) * Noteworthy changes in release 1.21.3 (2022-02-26) ** Fix computation of total bytes downloaded during FTP trasnfers (#61277) ** Add option to select TLS 1.3 on the command line ** Fix HSTS build issues on some 64-bit big-endian systems ** Hide password during status report in --no-verbose ** Remove a sprurious print statement that showed up even during --quiet ** Some more cleanups and bug-fixes * Noteworthy changes in release 1.21.2 (2021-09-07) ** Support for autoconf 2.71 ** Fix a double free in FTP when using an absolute path ** Release tarballs no longer have a dependency on Python. ** --page-requisites will now also download links marked as "alternate stylesheet" or "icon" * Noteworthy changes in release 1.21.1 (2021-01-09) ** Fix compilation on MacOS and Solaris 9 ** Resove bashism from configure.ac ** Fix a compilation warning on 32-bit systems * Changes in Wget 1.21 ** Improve the number of translated strings ** Remove all uses of alloca In some places the length of untrusted strings has been used, e.g. strings from the command line or from remote. ** Fix buffer overflows in progress bar code in some locales ** Fix two null pointer accesses ** Amend cookie file header to be recognized by the 'file' command ** Post Handshake Authentication for OpenSSL ** Require gettext version 0.19.3+ ** Add configure flags --enable-fsanitize-ubsan, --enable-fsanitize-asan and --enable-fsanitize-msan for gcc and clang ** Make several smaller fixes, enhance fuzzing, enhance building * Changes in Wget 1.20.3 ** Fixed a buffer overflow vulnerability * Changes in Wget 1.20.2 ** NTLM authentication will retry under certain cases * Changes in Wget 1.20.1 ** --xattr is no longer default since it introduces privacy issues. ** --xattr saves the Referer as scheme/host/port, user/pw/path/query/fragment are no longer saved to prevent privacy issues. ** --xattr saves the Original URL without user/password to prevent privacy issues. * Changes in Wget 1.20 ** Add new option `--retry-on-host-error` to treat local errors as transient and hence Wget will retry to download the file after a brief waiting period. ** Fixed multiple potential resource leaks as found by static analysis ** Wget will now not create an empty wget-log file when running with -q and -b switches together ** When compiled using the GnuTLS >= 3.6.3, Wget now has support for TLSv1.3 ** Now there is support for using libpcre2 for regex pattern matching ** When downloading over FTP recursively, one can now use the --{accept,reject}-regex switches to fine-tune the downloaded files ** Building Wget from the git sources now requires autoconf 2.63 or above. Building from the Tarballs works as it used to. * Changes in Wget 1.19.5 * Fix cookie injection (CVE-2018-0494) * Enable TLS1.3 with recent OpenSSL environment * New option --ciphers to set GnuTLS / OpenSSL ciphers directly * Updated CSS grammar to CSS 2.2 * Fixed several memleaks found by OSS-Fuzz * Fixed several buffer overflows found by OSS-Fuzz * Fixed several integer overflows found by OSS-Fuzz * Several minor bug fixes * Changes in Wget 1.19.4 * A major bug that caused GZip'ed pages to never be decompressed has been fixed * Support for Content-Encoding and Transfer-Encoding have been marked as experimental and disabled by default * Changes in Wget 1.19.3 * Prevent erroneous decompression of .gz and .tgz files with broken servers * Added support for HTTP 308 Permanent Redirect response * Fix a segfault in some cases where the Content-Type header is not sent * Support OpenSSL 1.1 builds without using deprecated features * Fix netrc file detection on Windows * Several minor bug fixes * Changes in Wget 1.19.2 * Fix CVE-2017-13089 (Stack overflow in HTTP protocol handling) * Fix CVE-2017-13090 (Heap overflow in HTTP protocol handling) * New option --compression for gzip Content-Encoding * New option --[no]-netrc to control .netrc parsing * Added GNU extensions to .netrc parsing * Improved IDNA 2003 compatibility * Fix VPATH issues * Improved and extended the test suite * Support Wayback Machine's X-Archive-Orig-last-modified * Several bug fixes * Changes in Wget 1.19.1 * Fix bugs, a regression, portability/build issues * Add new option --retry-on-http-error * Changes in Wget 1.19 * New option --use-askpass=COMMAND. Fetch user/password by calling an external program. * Use IDNA2008 (+ TR46 if available) through libidn2 * When processing a Metalink header, --metalink-index= allows to process the header's application/metalink4+xml files. * When processing a Metalink file, --trust-server-names enables the use of the destination file names specified in the Metalink file, otherwise a safe destination file name is computed. * When processing a Metalink file, enforce a safe destination path. Remove any drive letter prefix under w32, i.e. 'C:D:file'. Call libmetalink's metalink_check_safe_path() to prevent absolute, relative, or home paths: https://tools.ietf.org/html/rfc5854#section-4.1.2.1 https://tools.ietf.org/html/rfc5854#section-4.2.8.3 * When processing a Metalink file, --directory-prefix= sets the top of the retrieval tree to prefix for Metalink downloads. * When processing a Metalink file, reject downloaded files which don't agree with their own metalink:size value: https://tools.ietf.org/html/rfc5854#section-4.2.16 * When processing a Metalink file, with --continue resume partially downloaded files and keep fully downloaded files even if they fail the verification. * When processing a Metalink file, create the parent directories of a "path/file" destination file name: https://tools.ietf.org/html/rfc5854#section-4.1.2.1 https://tools.ietf.org/html/rfc5854#section-4.2.8.3 * On a recursive download, append a .tmp suffix to temporary files that will be deleted after being parsed, and create them readable/writable only by the owner. * New make target 'check-valgrind' * Fix several bugs * Fix compatibility issues * Changes in Wget 1.18 * By default, on server redirects to a FTP resource, use the original URL to get the local file name. Close CVE-2016-4971. This introduces a backward-incompatibility for HTTP->FTP redirects and any script that relies on the old behaviour must use --trust-server-names. * Check the HSTS file is not world-writable before using it. * Parse attributes on a recursive download. * Fix problem with SNI server names having trailing dot(s) * New options --bind-dns-address and --dns-servers. * When Wget is built with libiconv, it now converts non-ASCII URIs to the locale's codeset when it creates files. The encoding of the remote files and URIs is taken from --remote-encoding, defaulting to UTF-8. The result is that non-ASCII URIs and files downloaded via HTTP/HTTPS and FTP will have names on the local filesystem that correspond to their remote names. * Changes in Wget 1.17.1 * Fix compile error when IPv6 is disabled or SSL is not present. * Fix HSTS memory leak. * Fix progress output in non-C locales. * Fix SIGSEGV when -N and --content-disposition are used together. * Add --check-certificate=quiet to tell wget to not print any warning about invalid certificates. * Changes in Wget 1.17 ** Remove FTP passive to active fallback due to privacy concerns. ** Add support for --if-modified-since. ** Add support for metalink through --input-metalink and --metalink-over-http. ** Add support for HSTS through --hsts and --hsts-file. ** Add option to restrict filenames under VMS. ** Add support for --rejected-log which logs to a separate file the reasons why URLs are being rejected and some context around it. ** Add support for FTPS. ** Do not download/save file on error when --spider enabled ** Add --convert-file-only option. This option converts only the filename part of the URLs, leaving the rest of the URLs untouched. * Changes in Wget 1.16.3 ** Fix a regression introduced by wget 1.16.2 that --quiet is not really quiet anymore. * Changes in Wget 1.16.2 ** Native uuid generation on Windows ** Fix build on Solaris ** Allow progress bar on stderr when -o is used ** Accept 5-digit port numbers in FTP EPSV responses. ** Support older versions of flex. ** Updated translations. * Changes in Wget 1.16.1 ** Add --enable-assert configure option. ** Use pkg-config to check for libraries presence. ** Do not limit --secure-protocol=auto|pfs to TLSv1.0. ** Add --secure-protocol=TLSv1_1|TLSv1_2 . ** Full C89 source code compliance. ** Select and use the most secure authentication scheme with HTTP connections. ** Fix issues with turkish locales. ** Handle 504 Gateway Timeout. ** New option --crl-file to load Certificate Revocation Lists. ** Add valgrind support to tests suite. ** Fix an off-by-one problem in the progress bar (introduced in 1.16). * Changes in Wget 1.16 ** No longer create local symbolic links by default. Closes CVE-2014-4877. ** Use libpsl for verifying cookie domains. ** Default progress bar output changed. ** Introduce --show-progress to force display the progress bar. ** Introduce --no-config. The wgetrc files will not be read. ** Introduce --start-pos to allow starting downloads from a specified position. ** Fix a problem with ISA Server Proxy and keep-alive connections. * Changes in Wget 1.15 ** Add support for --method. ** Add support for file names longer than MAX_FILE. ** Support FTP listing for the FTP Server on Windows Server 2008 R2. ** Fix a regression when -c and --content-disposition are used together. ** Support shorthand URLs in an input file. ** Fix -c with servers that don't specify a content-length. ** Add support for MD5-SESS ** Do not fail on non fatal GNU TLS alerts during handshake. ** Add support for --https-only. When used wget will follow only HTTPS links in recursive mode. ** Support Perfect-Forward Secrecy in --secure-protocol. ** Fix a problem with some IRI links that are not followed when contained in a HTML document. ** Support some FTP servers that return an empty list with "LIST -a". ** Specify Host with the HTTP CONNECT method. ** Use the correct HTTP method on a redirection. * Changes in Wget 1.14 ** Add support for content-on-error. It allows to store the HTTP payload on 4xx or 5xx errors. ** Add support for WARC files. ** Fix a memory leak problem in the GNU TLS backend. ** Autoreconf works again for distributed tarballs. ** Print some diagnostic messages to stderr not to stdout. ** Report stdout close errors. ** Accept the --report-speed option. ** Enable client certificates when GNU TLS is used. ** Add support for TLS Server Name Indication. ** Accept the arguments --accept-regex and --reject-regex. ** The GNU TLS backend honors correctly the timeout value. ** Add support for RFC 2617 Digest Access Authentication. * Changes in Wget 1.13.4 ** Now --version and --help work again. ** Fix a build error on solaris 10 sparc. ** Now --timestamping and --continue work well together. ** Return a network failure when FTP downloads fail and --timestamping is specified. ** Fix a segfault on an incomplete STYLE tag. * Changes in Wget 1.13.3 ** Support HTTP/1.1 ** Now by default the GNU TLS library for secure connections, instead of OpenSSL. ** Fix some portability issues. ** Handle properly malformed status line in a HTTP response. ** Ignore zero length domains in $no_proxy. ** Set new cookies after an authorization failure. ** Exit with failure if -k is specified and -O is not a regular file. ** Cope better with unclosed html tags. ** Print diagnostic messages to stderr, not stdout. ** Do not use an additional HEAD request when --content-disposition is used, but use directly GET. ** Report the average transfer speed correctly when multiple URL's are specified and -c influences the transferred data amount. ** GNU TLS backend works again. ** Now --timestamping and --continue works well together. ** By default, on server redirects, use the original URL to get the local file name. Close CVE-2010-2252. This introduces a backward-incompatibility; any script that relies on the old behaviour must use --trust-server-names. ** Fix a problem when -k is used and some URLs are specified through CSS. ** Convert correctly URLs that need to be encoded to local files when following links. ** Use persistent connections with proxies supporting them. ** Print the total download time as part of the summary for recursive downloads. ** Now it is possible to specify a different startup configuration file through the --config option. ** Fix an infinite loop with the error ' has sprung into existence' on a network error and -nc is used. ** Now --adjust-extension does not modify the file extension if the file ends in .htm. ** Support HTTP/1.1 307 redirects keep request method. ** Now --no-parent doesn't fetch undesired files if HTTP and HTTPS are used by the same host on different pages. ** Do not attempt to remove the file if it is not in the accept rules but it is the output destination file. ** Introduce `show_all_dns_entries' to print all IP addresses corresponding to a DNS name when it is resolved. * Changes in Wget 1.12 ** Mailing list MOVED to bug-wget@gnu.org ** SECURITY FIX: It had been possible to trick Wget into accepting SSL certificates that don't match the host name, through the trick of embedding NUL characters into the certs' common name. Fixed by Joao Ferreira . ** Added support for CSS. This includes: - Parsing links from CSS files, and from CSS content found in HTML style tags and attributes. - Supporting conversion of links found within CSS content, when --convert-links is specified. - Ensuring that CSS files end in the ".css" filename extension, when --convert-links is specified. CSS support in Wget is thanks to Ted Mielczarek . ** Added support for Internationalized Resource Identifiers (IRIs, RFC 3987). When support is enabled (requires libidn and libiconv), links with non-ASCII bytes are translated from their source encoding to UTF-8 before percent-encoding. IRI support was added by Saint Xavier , as his project for the Google Summer of Code. ** Wget now provides more sensible exit status codes when downloads don't proceed as expected (see the manual). ** --default-page option (and associated wgetrc command) added to support alternative default names for index.html. ** --ask-password option (and associated wgetrc command) added to support password prompts at the console. ** The --input-file option now also handles retrieving links from an external file. ** The output generated by the --version option now includes information on how it was built, and the set of configure-time options that were selected. ** --html-extension has been renamed to --adjust-extension, to reflect the fact that it now also applies to CSS content. --html-extension is still acceptable, but is now deprecated. ** An "ascii" specifier is now accepted by --restrict-file-names, which forces the percent-encoding of all non-ASCII bytes ** Several previously existing, but undocumented .wgetrc options are now documented: save_headers, spider, and user_agent, auth_no_challenge, and keep_session_cookies. Also added documentation for the "lowercase" and "uppercase" values for --restrict-file-names, which had been present since Wget 1.11. * Changes in Wget 1.11.4 ** Fixed an issue (apparently a regression) where -O would refuse to download when -nc was given, even though the file didn't exist. ** Fixed a situation where Wget could abort with --continue if the remote server gives a content-length of zero when the file exists locally with content. ** Fixed a crash on some systems, due to Wget casting a pointer-to-long to a pointer-to-time_t. ** Translation updates for Catalan. * Changes in Wget 1.11.3 ** Downgraded -N with -O to a warning, rather than an error. ** Translation updates * Changes in Wget 1.11.2 ** Fixed a problem in authenticating over HTTPS through a proxy. (Regression in 1.11 over 1.10.2.) ** The combination of -r or -p with -O, which was disallowed in 1.11, has been downgraded to a warning in 1.11.2. (-O and -N, which was never meaningful, is still an error.) ** Further improvements to progress bar displays in non-English locales (too many spaces could be inserted, causing the display to scroll). ** Successive invocations of Wget on FTP URLS, with --no-remove-listing and --continue, was causing Wget to append, rather than replace, information in the .listing file, and thereby download the same files multiple times. This has been fixed in 1.11.2. ** Wget 1.11 no longer allowed ".." to persist at the beginning of URLs, for improved conformance with RFC 3986. However, this behavior presents problems for some FTP setups, and so they are now preserved again, for FTP URLs only. * Changes in Wget 1.11.1. ** Interrupted downloads no longer result in renaming the file (regression in 1.11 over 1.10.2). ** Progress bar now displays correctly in non-English locales (and a related assertion failure was fixed). ** Wget no longer issues a GET request over HTTP for files it should know it's not going to download (regression in 1.11 over 1.10.2). ** Added option --auth-no-challenge, to support broken pre-1.11 authentication-before-server-challenge, which turns out to still be useful for some limited cases. ** Documentation of accept/reject lists in the manual's "Types of Files" section now explains various aspects of their behavior that may be surprising, and notes that they may change in the future. ** Documentation of --no-parents now explains how a trailing slash, or lack thereof, in the specified URL, will affect behavior. * Changes in Wget 1.11. ** Timestamping now uses the value from the most recent HTTP response, rather than the first one it got. ** Authentication information is no longer sent as part of the Referer header in recursive fetches. ** No authentication credentials are sent until a challenge is issued, for improved security. Authentication handling is still not RFC-compliant, as once a Basic challenge has been received, it will assume it can send credentials to any URL at that same host, and not just the ones at or below the original authenticated location. Credentials for Digest authentication are still never saved or issued automatically, and continue to require a challenge for each resource. ** Added --max-redirect option, allowing the user to specify what should be the maximum number of HTTP redirects to follow. ** Wget now supports saving HTTP downloads using file names specified by the `Content-Disposition' header. This is a standard way of specifying the file name used by many web dynamically generated pages. However, the current implementation is inefficient, and known to have bugs. It is EXPERIMENTAL only, and not enabled by default. Use --content-disposition to enable it. ** The new option `--ignore-case' makes Wget ignore case when matching files, directories, and wildcards. This affects the -X, -I, -A, and -R options, as well as globbing in FTP URLs. ** ETA projection is now displayed in "dot" progress output as well as in the default progress bar. (The dot progress is used by default when logging Wget's output to file using the `-o' option.) ** The "lockable boolean" argument type is no longer supported. It was only used by the passive_ftp .wgetrc setting. If you're running broken scripts or Perl modules that unconditionally specify `--passive-ftp' and your firewall disallows it, you can override them by replacing wget with a script that execs wget "$@" --no-passive-ftp. ** The source code has been migrated to Mercurial. The repositories are available at http://hg.addictivecode.org/. Prior to this, the source code was hosted on Subversion (migrated from the original CVS); you can still get access to older tags and branches for Wget in the Subversion repository at http://addictivecode.org/svn/wget/. * Changes in Wget 1.10. ** Downloading files larger than 2GB, sometimes referred to as "large files", now works on systems that support them. This includes the majority of modern Unixes, as well as MS Windows. ** IPv6 is now supported by Wget. Unlike the experimental code in 1.9, this version supports dual-family systems. The new flags `--inet4' and `--inet6' (or `-4' and `-6' for short) force the use of IPv4 and IPv6 respectively. Note that IPv6 support has not yet been tested on Windows. ** Microsoft's proprietary "NTLM" method of HTTP authentication is now supported. This authentication method is undocumented and only used by IIS. Note that *proxy* authentication is not supported in this release; you can only authenticate to the target web site. ** Wget no longer truncates partially downloaded files when download has to start over because the server doesn't support Range. Instead, with such servers Wget now simply ignores the data up to the byte where the last attempt left off, and only then continues appending to the file. That way the downloaded file never shrinks, and download retries from servers without support for partial downloads work even when downloading to stdout. ** SSL/TLS changes: *** SSL/TLS downloads now attempt to verify the server's certificate against the recognized certificate authorities. This requires CA certificates to have been installed in a location visible to the OpenSSL library. If this is not the case, you can get the bundle yourself from a source you trust (for example, the bundle extracted from Mozilla available at http://curl.haxx.se/docs/caextract.html), and point Wget to the PEM file using the `--ca-certificate' command-line option or the corresponding `.wgetrc' command. *** Secure downloads now verify that the host name in the URL matches the "common name" in the certificate presented by the server. *** Although the above checks provide more secure downloads, they unavoidably break interoperability with some sites that worked with previous versions, particularly those using self-signed, expired, or otherwise invalid certificates. If you encounter "certificate verification" errors or complaints that "common name doesn't match requested host name" and are convinced of the site's authenticity, you can use `--no-check-certificate' to bypass both checks. *** Talking to SSL/TLS servers over proxies now actually works. Previous versions of Wget erroneously sent GET requests for https URLs. Wget 1.10 utilizes the CONNECT method designed for this purpose. *** The SSL/TLS-related options have been redesigned and, for the first time, documented in the manual. The old, undocumented, options are no longer supported. ** Passive FTP is now the default FTP transfer mode. Use `--no-passive-ftp' or specify `passive_ftp = off' in your init file to revert to the old behavior. ** The `--header' option can now be used to override generated headers. For example, `wget --header="Host: foo.bar" http://127.0.0.1' tells Wget to connect to localhost, but to specify "foo.bar" in the `Host' header. In previous versions such use of `--header' lead to duplicate headers in HTTP requests. ** The responses without headers, aka "HTTP 0.9" responses, are detected and handled. Although HTTP 0.9 has long been obsolete, it is still occasionally used, sometimes by accident. ** The progress bar is now updated regularly even when the data does not arrive from the network. ** Wget no longer preserves permissions of files retrieved by FTP by default. Anonymous FTP servers frequently use permissions like "664", which might not be what the user wants. The new option `--preserve-permissions' and the corresponding `.wgetrc' variable can be used to revert to the old behavior. ** The new option `--protocol-directories' instructs Wget to also use the protocol name as a directory component of local file names. ** Options that previously unconditionally set or unset various flags are now boolean options that can be invoked as either `--OPTION' or `--no-OPTION'. Options that required an argument "on" or "off" have also been changed this way, but they still accept the old syntax for backward compatibility. For example, instead of `--glob=off' you can write `--no-glob'. Allowing `--no-OPTION' for every `--OPTION' and the other way around is useful because it allows the user to override non-default behavior specified via `.wgetrc'. ** The new option `--keep-session-cookies' causes `--save-cookies' to save session cookies (normally only kept in memory) along with the permanent ones. This is useful because many sites track important information, such as whether the user has authenticated, in session cookies. With this option multiple Wget runs are treated as a single browser session. ** Wget now supports the --ftp-user and --ftp-password command switches to set username and password for FTP, and the --user and --password command switches to set username and password for both FTP and HTTP. The --http-passwd and --proxy-passwd command switches have been renamed to --http-password and --proxy-password respectively, and the related http_passwd and proxy_passwd .wgetrc commands to http_password and proxy_password respectively. The login and passwd .wgetrc commands have been deprecated. * `wget -b' now works correctly under Windows. * Wget 1.9.1 is a bugfix release with no user-visible changes. * Changes in Wget 1.9. ** It is now possible to specify that POST method be used for HTTP requests. For example, `wget --post-data="id=foo&data=bar" URL' will send a POST request with the specified contents. ** IPv6 support is available, although it's still experimental. ** The `--timeout' option now also affects DNS lookup and establishing the TCP connection. Previously it only affected reading and writing data. Those three timeouts can be set separately using `--dns-timeout', `--connection-timeout', and `--read-timeout', respectively. ** Download speed shown by the progress bar is based on the data recently read, rather than the average speed of the entire download. The ETA projection is still based on the overall average. ** It is now possible to connect to FTP servers through FWTK firewalls. Set ftp_proxy to an FTP URL, and Wget will automatically log on to the proxy as "username@host". ** The new option `--retry-connrefused' makes Wget retry downloads even in the face of refused connections, which are otherwise considered a fatal error. ** The new option `--no-dns-cache' may be used to prevent Wget from caching DNS lookups. ** Wget no longer escapes characters in local file names based on whether they're appropriate in URLs. Escaping can still occur for nonprintable characters or for '/', but no longer for frequent characters such as space. You can use the new option --restrict-file-names to relax or strengthen these rules, which can be useful if you dislike the default or if you're downloading to non-native partitions. ** Handling of HTML comments has been dumbed down to conform to what users expect and other browsers do: instead of being treated as SGML declaration, a comment is terminated at the first occurrence of "-->". Use `--strict-comments' to revert to the old behavior. ** Wget now correctly handles relative URIs that begin with "//", such as "//img.foo.com/foo.jpg". ** Boolean options in `.wgetrc' and on the command line now accept values "yes" and "no" along with the traditional "on" and "off". ** It is now possible to specify decimal values for timeouts, waiting periods, and download rate. For instance, `--wait=0.5' now works as expected, as does `--dns-timeout=0.5' and even `--limit-rate=2.5k'. * Wget 1.8.2 is a bugfix release with no user-visible changes. * Wget 1.8.1 is a bugfix release with no user-visible changes. * Changes in Wget 1.8. ** A new progress indicator is now available and used by default. You can choose the progress bar type with `--progress=TYPE'. Two types are available, "bar" (the new default), and "dot" (the old dotted indicator). You can permanently revert to the old progress indicator by putting `progress = dot' in your `.wgetrc'. ** You can limit the download rate of the retrieval using the `--limit-rate' option. For example, `wget --limit-rate=15k URL' will tell Wget not to download the body of the URL faster than 15 kilobytes per second. ** Recursive retrieval and link conversion have been revamped: *** Wget now traverses links breadth-first. This makes the calculation of depth much more reliable than before. Also, recursive downloads are faster and consume *significantly* less memory than before. *** Links are converted only when the entire retrieval is complete. This is the only safe thing to do, as only then is it known what URLs have been downloaded. *** BASE tags are handled correctly when converting links. Since Wget already resolves when resolving handling URLs, link conversion now makes the BASE tags point to an empty string. *** HTML anchors are now handled correctly. Links to an anchor in the same document (), which used to confuse Wget, are now converted correctly. *** When in page-requisites (-p) mode, no-parent (-np) is ignored when retrieving for inline images, stylesheets, and other documents needed to display the page. *** Page-requisites (-p) mode now works with frames. In other words, `wget -p URL-THAT-USES-FRAMES' will now download the frame HTML files, and all the files that they need to be displayed properly. ** `--base' now works conjunction with `--input-file', providing a base for each URL and thereby allowing the URLs in the file to be relative. ** If a host has more than one IP address, Wget uses the other addresses when accessing the first one fails. ** Host directories now contain port information if the URL is at a non-standard port. ** Wget now supports the robots.txt directives specified in . ** URL parser has been fixed, especially the infamous overzealous quoting. Wget no longer dequotes reserved characters, e.g. `%3F' is no longer translated to `?', nor `%2B' to `+'. Unsafe characters which are not reserved are still escaped, of course. ** No more than 20 successive redirections are allowed. * Wget 1.7.1 is a bugfix release with no user-visible changes. * Changes in Wget 1.7. ** SSL (`https') pages now work if you compile Wget with SSL support; use the `--with-ssl' configure flag. You need to have OpenSSL installed. ** Cookies are now supported. Wget will accept cookies sent by the server and return them in later requests. Additionally, it can load and save cookies to disk, in the same format that Netscape uses. ** "Keep-alive" (persistent) HTTP connections are now supported. Using keep-alive allows Wget to share one TCP/IP connection for many retrievals, making multiple-file downloads faster and less stressing for the server and the network. ** Wget now recognizes FTP directory listings generated by NT and VMS servers. ** It is now possible to recurse through FTP sites where logging in puts you in some directory other than '/'. ** You may now use `~' to mean home directory in `.wgetrc'. For example, `load_cookies = ~/.netscape/cookies.txt' works as you would expect. ** The HTML parser has been rewritten. The new one works more reliably, allows finer-grained control over which tags and attributes are detected, and has better support for some features like correctly skipping comments and declarations, decoding entities, etc. It is also more general. ** tags are now respected. ** Wget's internal tables now use hash tables instead of linked lists where appropriate. This results in huge speedups when retrieving large sites (thousands of documents). ** Wget now has a man page, automatically generated from the Texinfo documentation. (The last version that shipped with a man page was 1.4.5). To get this, you need to have pod2man from the Perl distribution installed on your system. * Changes in Wget 1.6 ** Administrative changes. *** Maintainership. Due to Hrvoje being plagued with a "real job", Dan Harkless is the most active maintainer (not that he doesn't have a real job as well). Hrvoje still participates occasionally, and both are being helped by many other people. *** Web page. Thanks to Jan Prikryl, Wget has an "official" web page. Take a look at: http://sunsite.dk/wget/ *** Anonymous CVS. Thanks to ever-helpful Karsten Thygesen, Wget sources are now available at an anonymous CVS server. Take a look at the web page for downloading instructions. ** New -K / --backup-converted / backup_converted = on option causes files modified due to -k to be saved with a .orig prefix before being changed. When using -N as well, it is these .orig files that are compared against the server. ** New --follow-tags / follow_tags = ... option allows you to restrict Wget to following only certain HTML tags when doing a recursive retrieval. -G / --ignore-tags / ignore_tags = ... is just the opposite -- all tags but the ones you specify will be followed. ** New --waitretry / waitretry = SECONDS option allows waiting between retries of failed downloads. Wget will use "linear" backoff, waiting 1 second after the first failure, 2 after the second, up to SECONDS. waitretry is set to 10 by default in the system wgetrc. ** New -p / --page-requisites / page_requisites = on option causes Wget to download all ancillary files necessary to display a given HTML page properly (e.g. inlined images). ** New -E / --html-extension / html_extension = on option causes Wget to append ".html" to text/html filenames not ending in regexp "\.[Hh][Tt][Mm][Ll]?". ** New type of .wgetrc command -- "lockable Boolean". Can be set to on, off, always, or never. This allows the .wgetrc to override the commandline. So far, passive_ftp is the only .wgetrc command which takes a lockable Boolean. ** A number of new translation files have been added. ** New --bind-address / bind_address =
option for people on hosts bound to multiple IP addresses. ** wget now accepts (illegal per HTTP spec) relative URLs in HTTP redirects. * Wget 1.5.3 is a bugfix release with no user-visible changes. * Wget 1.5.2 is a bugfix release with no user-visible changes. * Wget 1.5.1 is a bugfix release with no user-visible changes. * Changes in Wget 1.5.0 ** Wget speaks many languages! On systems with gettext(), Wget will output messages in the language set by the current locale, if available. At this time we support Czech, German, Croatian, Italian, Norwegian and Portuguese. ** Opie (Skey) is now supported with FTP. ** HTTP Digest Access Authentication (RFC2069) is now supported. ** The new `-b' option makes Wget go to background automatically. ** The `-I' and `-X' options now accept wildcard arguments. ** The `-w' option now accepts suffixes `s' for seconds, `m' for minutes, `h' for hours, `d' for days and `w' for weeks. ** Upon getting SIGHUP, the whole previous log is now copied to `wget-log'. ** Wget now understands proxy settings with explicit usernames and passwords, e.g. `http://user:password@proxy.foo.com/'. ** You can use the new `--cut-dirs' option to make Wget create less directories. ** The `;type=a' appendix to FTP URLs is now recognized. For instance, the following command will retrieve the welcoming message in ASCII type transfer: wget "ftp://ftp.somewhere.com/welcome.msg;type=a" ** `--help' and `--version' options have been redone to conform to standards set by other GNU utilities. ** Wget should now be compilable under MS Windows environment. MS Visual C++ and Watcom C have been used successfully. ** If the file length is known, percentages are displayed during download. ** The manual page, now hopelessly out of date, is no longer distributed with Wget. * Wget 1.4.5 is a bugfix release with no user-visible changes. * Wget 1.4.4 is a bugfix release with no user-visible changes. * Changes in Wget 1.4.3 ** Wget is now a GNU utility. ** Can do passive FTP. ** Reads .netrc. ** Info documentation expanded. ** Compiles on pre-ANSI compilers. ** Global wgetrc now goes to /usr/local/etc (i.e. $sysconfdir). ** Lots of bugfixes. * Changes in Wget 1.4.2 ** New mirror site at ftp://sunsite.auc.dk/pub/infosystems/wget/, thanks to Karsten Thygesen. ** Mailing list! Mail to wget-request@sunsite.auc.dk to subscribe. ** New option --delete-after for proxy prefetching. ** New option --retr-symlinks to retrieve symbolic links like plain files. ** rmold.pl -- script to remove files deleted on the remote server ** --convert-links should work now. ** Minor bugfixes. * Changes in Wget 1.4.1 ** Minor bugfixes. ** Added -I (the opposite of -X). ** Dot tracing is now customizable; try wget --dot-style=binary * Changes in Wget 1.4.0 ** Wget 1.4.0 [formerly known as Geturl] is an extensive rewrite of Geturl. Although many things look suspiciously similar, most of the stuff was rewritten, like recursive retrieval, HTTP, FTP and mostly everything else. Wget should be now easier to debug, maintain and, most importantly, use. ** Recursive HTTP should now work without glitches, even with Location changes, server-generated directory listings and other naughty stuff. ** HTTP regetting is supported on servers that support Range specification. WWW authorization is supported -- try wget http://user:password@hostname/ ** FTP support was rewritten and widely enhanced. Globbing should now work flawlessly. Symbolic links are created locally. All the information the Unix-style ls listing can give is now recognized. ** Recursive FTP is supported, e.g. wget -r ftp://gnjilux.cc.fer.hr/pub/unix/util/ ** You can specify "rejected" directories, to which you do not want to enter, e.g. with wget -X /pub ** Time-stamping is supported, with both HTTP and FTP. Try wget -N URL. ** A new texinfo reference manual is provided. It can be read with Emacs, standalone info, or converted to HTML, dvi or postscript. ** Fixed a long-standing bug, so that Wget now works over SLIP connections. ** You can have a system-wide wgetrc (/usr/local/lib/wgetrc by default). Settings in $HOME/.wgetrc override the global ones, of course :-) ** You can set up quota in .wgetrc to prevent sucking too much data. Try `quota = 5M' in .wgetrc (or quota = 100K if you want your sysadmin to like you). ** Download rate is printed after retrieval. ** Wget now sends the `Referer' header when retrieving recursively. ** With the new --no-parent option Wget can retrieve FTP recursively through a proxy server. ** HTML parser, as well as the whole of Wget was rewritten to be much faster and less memory-consuming (yes, both). ** Absolute links can be converted to relative links locally. Check wget -k. ** Wget catches hangup, filtering the output to a log file and resuming work. Try kill -HUP %?wget. ** User-defined headers can be sent. Try wget http://fly.cc.her.hr/ --header='Accept-Charset: iso-8859-2' ** Acceptance/Rejection lists may contain wildcards. ** Wget can display HTTP headers and/or FTP server response with the new `-S' option. It can save the original HTTP headers with `-s'. ** socks library is now supported (thanks to Antonio Rosella ). Configure with --with-socks. ** There is a nicer display of REST-ed output. ** Many new options (like -x to force directory hierarchy, or -m to turn on mirroring options). ** Wget is now distributed under GNU General Public License (GPL). ** Lots of small features I can't remember. :-) ** A host of bugfixes. * Changes in Geturl 1.3 ** Added FTP globbing support (ftp://fly.cc.fer.hr/*) ** Added support for no_proxy ** Added support for ftp://user:password@host/ ** Added support for %xx in URL syntax ** More natural command-line options ** Added -e switch to execute .geturlrc commands from the command-line ** Added support for robots.txt ** Fixed some minor bugs * Geturl 1.2 is a bugfix release with no user-visible changes. * Changes in Geturl 1.1 ** REST supported in FTP ** Proxy servers supported ** GNU getopt used, which enables command-line arguments to be ordered as you wish, e.g. geturl http://fly.cc.fer.hr/ -vo log is the same as geturl -vo log http://fly.cc.fer.hr/ ** Netscape-compatible URL syntax for HTTP supported: host[:port]/dir/file ** NcFTP-compatible colon URL syntax for FTP supported: host:/dir/file ** supported ** autoconf supported ---------------------------------------------------------------------- Copyright information: Copyright (C) 1997-2024 Free Software Foundation, Inc.
