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 + should make it treat fewer high-bit characters as non-printable (when + appropriate). + + - If rsync received an empty file list when pulling files, it would + output an "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. - - 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.) - 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). + - 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. - - The combination of --verbose and --dry-run now mentions changes in - directories and it now includes the full update information that - would be output without --dry-run at higher levels of verbosity. + - 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. - - Avoid a mkdir warning when removing a directory in the destination - that already exists in the --backup-dir. + - Fixed a case where the generator might try to tweak the write + permissions of a read-only directory in list-only mode. - - An OS that has a binary mode for its files (such as cygwin0 needed - setmode(fd, O_BINARY) called on the temp-file we opened with - mkstemp(). (Fix derived from the cygwin's rsync package.) + - 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 potential hang when verbosity is high, the client side is - the sender, and the file-list is large. + - Fixed the accidental disabling of --backup during the --delete-after + processing. - - We now check if the OS doesn't support using mknod() for creating - FIFOs and sockets, and compile-in using mkfifo() and socket() when - necessary. + - Restored the ability to use the --address option in client mode (in + addition to its use in daemon mode). - - Fixed an off-by-one error in the handling of --max-delete=N. + - 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. - - One place in the code wasn't checking if fork() failed. + - When --existing skips a directory with extra verbosity, don't refer + to it as a "file". - - The "ignore nonreadable" daemon parameter no longer affects symlinks - that are being copied, even if they point nowhere. + - 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. - - If the OS does not have lchown() and its chown() tries to set the - referent of a symlink (as it should), we no longer try to set the - user and group of a symlink. + - Fixed a bug where hard-linking a group of files might fail if the + generator hasn't created the destination directory yet. - - 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. + - 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 --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. + - 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. - - 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 (i.e. rsync might have - exited with an error for large files). - - - If a daemon can't open the specified log file (i.e. syslog is not - being used), die without crashing. We also try to output an error - about the failure (which will only be seen if --no-detach was - specified). - - - A local transfer no longer duplicates all its include/exclude options - by sending the forked process a copy of the list it already has. + - Fixed a compatibility problem when using --cvs-ignore (-C) and + sending files to an older rsync without using --delete. 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 on the receiving side incrementally as each directory in the - transfer is being processed (which makes it more efficient than the - default, before-the-transfer behavior of --delete). Note that the - --del option is implemented as an internally-defined popt alias, so - an rsync daemon that refuses "delete" (which, for safety's sake, - really matches "delete*") will still refuse all delete options. The - default --delete behavior is also explicitly selectable via - --delete-before. - - - All the --delete-WHEN options are now more memory efficient: - Previously an entire 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. - - - Added the --copy-dest option, which works like --link-dest except - that it includes copies of identical files. - - - 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.) - - - Added the --max-size option. (Promoted from the patches dir.) - - - The daemon-mode options were separated from the normal rsync options - so that they can't be mixed together. This makes it impossible to - start a daemon that had improper default option values that could - cause problems (such as a hang or an abort) when a client connects. - - - 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". A command-line option - will 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. - - - 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 - option kluges (e.g. the age-old use of "-r --exclude="/*/*" for a - non-recursive listing). This option is used automatically 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 can result in - 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.) - - - 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. + - 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). - - Documented the "max verbosity" setting for rsyncd.conf. (This - setting was added a couple releases ago, but left undocumented.) + - 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. - - The sender and the generator now double-check the file-list index - they are given, and refuse to operate on a directory index (since - that would indicate that something had gone very wrong). + - 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 the --itemize-changes (-i) option that is a way to output the - list of files that got transferred and/or changed in any way, and how - they changed. The effect is the same as specifying --log-format - "%i %n%L" (see the rsyncd.conf manpage). Works with --dry-run. + - 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). - - Added the --fuzzy 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.) - - SUPPORT FILES: - - - Added support/atomic-rsync -- 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 support/mnt-excl 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 support/savetransfer.c -- 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) or provides a way to help debug a protocol error. - - - Added support/rrsync -- my 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. - - - Improved the option descriptions in the --help text. + - If the daemon can't open the log-file specified in rsyncd.conf, fall + back to using syslog. This is better than a (typically) totally + silent failure (since a daemon is not usually run with --no-detach). INTERNAL: - - Added better checking of the checksum-header values that come over - the socket. - - - Merged the various delete-file 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. + - Rsync now calls setlocale(LC_CTYPE, ""). - - Defined int32 in a way that ensures that the build dies if we can't - find a variable with at least 32 bits. - - - 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. - - PROTOCOL DIFFERENCES FOR VERSION 29: - - - If --inplace is specified, the generator sends an extra byte after - each index integer indicating what kind of basis file is being used - for the transfer (see the FNAMECMP_* defines). - - - 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 enabled. - - - 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 still initiate a send of the filter - rules to the receiver, but it only includes those rules that are - receiver-specific. 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). + BUILD CHANGES: - - A protocol-29 batch file includes a bit for the setting of the --dirs - option. Also, the shell script created by --write-batch will use the - --filter option instead of --exclude-from to capture any filter rules. + - Fixed a bug in the SUPPORT{,_HARD}_LINKS defines which prevented + rsync from being built without symlink or hard-link support. - BUILD CHANGES: + - You can use --disable-locale to turn off any use of setlocale(). - - Handle an operating system that use mkdev() in place of makedev(). + - Configure now disables the use of mkstemp() under HP-UX (since they + refuse to fix its broken handling of large files). - - Improved configure to better handle cross-compiling. + - 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.
