NEWS for rsync 3.0.5 (28 Dec 2008) Protocol: 30 (unchanged) Changes since 3.0.4: 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 support/atomic-rsync script able to perform a fully atomic update of the copied hierarchy when the destination is setup using a particular symlink idiom. NEWS for rsync 3.0.4 (6 Sep 2008) Protocol: 30 (unchanged) Changes since 3.0.3: 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) Protocol: 30 (unchanged) Changes since 3.0.2: 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 man pages, 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. NEWS for rsync 3.0.2 (8 Apr 2008) Protocol: 30 (unchanged) Changes since 3.0.1: BUG FIXES: - Fixed a potential buffer overflow in the xattr code. ENHANCEMENTS: - None. DEVELOPER RELATED: - The RPM spec file was improved to install more useful files. - A few developer-oriented scripts were moved from the support dir to the packaging dir. NEWS for rsync 3.0.1 (3 Apr 2008) Protocol: 30 (unchanged) Changes since 3.0.0: 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 support/rrsync script to work with the latest options that rsync sends (including its flag-specifying use of -e to the server). 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) Protocol: 30 (changed) Changes since 2.6.9: 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 transfering 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 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) Protocol: 29 (unchanged) Changes since 2.6.8: 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 man page 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) Protocol: 29 (unchanged) Changes since 2.6.7: 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) Protocol: 29 (unchanged) Changes since 2.6.6: 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 multibyte 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/-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 man page 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) Protocol: 29 (unchanged) Changes since 2.6.5: 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 support/rrsync script has been upgraded to verify the args of options that take args (instead of rejecting any such options). The script was also changed to try to be more secure and to fix a problem in the parsing of a pull operation that has multiple sources. - 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) Protocol: 29 (unchanged) Changes since 2.6.4: 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 man pages 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) Protocol: 29 (changed) Changes since 2.6.3: 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) Protocol: 28 (unchanged) Changes since 2.6.2: 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 over- writing 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 man page 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 man page. - 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 man pages, 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) Protocol: 28 (unchanged) Changes since 2.6.1: 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) Protocol: 28 (changed) Changes since 2.6.0: 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 mis- understood 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) Protocol: 27 (changed) Changes since 2.5.7: 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) Protocol: 26 (unchanged) Changes since 2.5.6: 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) Protocol: 26 (unchanged) Changes since 2.5.5: 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) Protocol: 26 (unchanged) Changes since 2.5.4: 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) Protocol: 26 (unchanged) Changes since 2.5.3: 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) Protocol: 26 (unchanged) Changes since 2.5.2: 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 man page (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) Protocol: 26 (changed) Changes since 2.5.1: 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. 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) Protocol: 25 (unchanged) Changes since 2.5.0: BUG FIXES: * Fix for segfault in --daemon mode configuration parser.

(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) Protocol: 25 (changed) Changes since 2.4.6: 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.
