(Wayne Davison) - - * Length of csum2 is now per-file starting with protocol verison - 27. (J.W. Schultz) - - * Per-file dynamic block size is now sqrt(file length). - The per-file checksum size is determined according - to an algorythm 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. +NEWS for rsync 2.6.5 (UNRELEASED) +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: - * 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. - - - "**/foo" now matches at the base of the transfer (i.e. /foo). - - - An 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. - - - 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" (for instance). - - * 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. + - 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. - * Make --link-dest honor the absence of -p, -o, and -g. + - Fixed a bug in the transfer of a single file when -H is specified + that might have caused an infinite loop or perhaps a crash. - * Made rsync treat a trailing slash in the destination in a more - consistent manner. + - Fixed a case where the generator might try to tweak the write + permissions of a read-only directory in list-only mode. - * Fixed file I/O error detection. (John Van Essen) + - 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 a compression (-z) bug when syncing a mostly-matching file - that contains already-compressed data. (Yasuoka Masahiko and - Wayne Davison) + - Fixed the accidental disabling of --backup during the --delete-after + processing. - * Fixed a bug in the --backup code that could cause deleted files - to not get backed up. + - Restored the ability to use the --address option in client mode (in + addition to its use in daemon mode). - * Call setgroups() in a more portable manner. + - 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. - * Improved file-related error messages to better indicate exactly - what pathname failed. (Wayne Davison) + - When --existing skips a directory with extra verbosity, refer to it + as a "directory", not a "file". - * Fixed some bugs in the handling of --delete and --exclude when - using the --relative (-R) option. (Wayne Davison) + - 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 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) + - Fixed a bug where hard-linking a group of files might fail if the + generator hasn't created a needed destination directory yet. - * Detect and report when open or opendir succeed but read and - readdir fail caused by network filesystems issues and truncated - files. (David Norwood, Michael Brown, J.W. Schultz) + - 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. - INTERNAL: + - 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. - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) + - Fixed a compatibility problem when using --cvs-ignore (-C) and + sending files to an older rsync without using --delete. - * Simplified some of the option-parsing code. (Wayne Davison) + - Make sure that a "- !" or "+ !" include/exclude pattern does not + trigger the list-clearing action that is reserved for "!". - * Some cleanup made to the exclude code, as well as some new - defines added to enhance readability. (Wayne Davison) + - Avoid a timeout in the generator when the sender/receiver aren't + handling the generator's checksum output quickly enough. - * 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) + - Fixed the ommission of some directories in the delete processing when + --relative (-R) was combined with a source path that had a trailing + slash. + - Make sure that --max-size doesn't affect a device or a symlink. -NEWS for rsync version 2.5.7: -Protocol: 26 (unchanged) -Changes since version 2.5.6: + - 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.) - SECURITY: + - If a source filename ends with "..", treat it as if "../" had been + specified (so that we don't copy files to the parent dir of the + destination). - * Fix buffer handling bugs. (Andrew Tridgell, Martin Pool, Paul - Russell, Andrea Barisani) + - 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. -NEWS for rsync version 2.5.6, aka the dwd-between-jobs release -Protocol: 26 (unchanged) -Changes since version 2.5.5: + - Improved one "if" in the deletion code that was only checking errno + for ENOTEMPTY when it should have also been checking for EEXIST. 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. + - 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). - * If the file name given to --include-from or --exclude-from is "-", - rsync will read from standard input. (J.W. Schultz) + - 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. - * New option --link-dest which is like --compare-dest except that - unchanged files are hard-linked in to the destination directory. - (J.W. Schultz) + - 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. - * Don't report an error if an excluded file disappears during an - rsync run. (Eugene Chupriyanov and Bo Kersey) + - 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.) - * Added .svn to --cvs-exclude list to support subversion. (Jon - Middleton) + - 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). - * 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: + - 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 failure (since a + daemon is not usually run with the --no-detach option that was + necessary to see the error on stderr). - * Fix "forward name lookup failed" errors on AIX 4.3.3. (John - L. Allen, Martin Pool) + - The man pages now consistently refer to an rsync daemon as a "daemon" + to distinguish it from a server in a non-daemon transfer. - * 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) + - 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). - * 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) + INTERNAL: - * Prevent infinite recursion in cleanup code under certain circumstances. - (Sviatoslav Sviridov and Marc Espie) + - Rsync now calls setlocale(LC_CTYPE, "") to enable isprint() to better + discern which filename characters need to be escaped in messages. - * Fixed a bug that prevented rsync from creating intervening directories - when --relative-paths/-R is set. (Craig Barratt) + - Improved the naming of the log-file open/reopen/close functions. - * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara) + - Removed some protocol compatibility code that was only needed to help + someone running a pre-release of 2.6.4. - INTERNAL: + BUILD CHANGES: - * Many code cleanups and improved internal documentation. (Martin - Pool, Nelson Beebe) + - Fixed a bug in the SUPPORT{,_HARD}_LINKS defines which prevented + rsync from being built without symlink or hard-link support. - * Portability fixes. (Dave Dykstra and Wayne Davison) + - You can use --disable-locale to turn off any use of setlocale(). - * More test cases. (Martin Pool) + - Configure now disables the use of mkstemp() under HP-UX (since they + refuse to fix its broken handling of large files). - * Some test-case fixes. (Brian Poole, Wayne Davison) + - 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. - * Updated included popt to the latest vendor drop, version 1.6.4. - (Jos Backus) + - Some minor enhancements to the test scripts. - * Updated config.guess and config.sub to latest versions; this - means rsync should build on more platforms. (Paul Green) + - Added a few new diffs to the patches dir, including a patch that + enables the optional copying of extended attributes.
