(with trailing dot to make it 4 chars). + This changes the way deletions are logged in the daemon's log file. - * Shell wildcards are allowed in "auth users" lines. + - 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 with --verbose being the equivalent of a --log-format of + '%n%L' (which outputs the name and any symlink 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). + + BUG FIXES: - * Merged UNC rsync+ patch to support creation of standalone patch - sets. By Bert J. Dempsey and Debra Weiss, updated by Jos - Backus. + - 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). - * 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. + - The combination of --verbose and --dry-run now mentions the full list + of changes that would be output without --dry-run. - ENHANCEMENTS + - Avoid a mkdir warning when removing a directory in the destination + that already exists in the --backup-dir. - * Include/exclude cluestick: with -vv, print out whether files are - included or excluded and why. + - 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 the cygwin's 2.6.3 rsync package.) - * Many error messages have more friendly explanations and more - details. + - Fixed a potential hang when verbosity is high, the client side is + the sender, and the file-list is large. - * Manual page improvements plus scanty protocol documentation. + - 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. - * 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. + - Fixed an off-by-one error in the handling of --max-delete=N. - * 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. + - One place in the code wasn't checking if fork() failed. - * More details in --version, including note about whether 64-bit - files, symlinks and hardlinks are supported. + - The "ignore nonreadable" daemon parameter used to erroneously affect + symlinks that pointed to a non-existent file. This has been fixed. - * MD4 code may use less CPU cycles. + - 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. - * Use mkstemp on systems where it is secure. If we use mktemp, - explain that we do it in a secure way. + - 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. - * --whole-file is the default when source and target are on the - local machine. + - 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. - BUG FIXES: + - 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). + + - 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). + + - When --progress is specified, the output of items that the generator + is creating (e.g. dirs, symlinks) is now integrated into the progress + output without overlapping it. (Requires protocol 29.) + + 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 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. + + - 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 (for files + inside the transfer). + + - Added support for specifying multiple --compare-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 when a client connects (e.g. a hang or an abort). + + - 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 and + --link-dest. (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 + 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 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 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 in any way and how they + changed. The effect is the same as specifying a --log-format of + "%i %n%L" (see the rsyncd.conf manpage). Works with --dry-run too. + + - 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.) + + - Added the --remove-sent-files option, which lets you move files + between systems. + + - When building under windows, the default for --daemon is now to + avoid detaching, requiring the new --detach option to force rsync + to detach. + + - 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) or provides a way to help debug a protocol error. + + - Added rrsync to the support dir: this is 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. + + 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. + + - 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: + + - 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 either the receiver or the + sender is now outputting all the file-change info). + + - If --inplace is specified, the generator flags any transfer that is + using an alternate basis file so that the sender can use the entire + file in the rsync algorithm (unlike a normal --inplace update). + + - 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 excludes, a + client sender will now initiate a send of the filter 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 + is often empty in this scenario. + + - 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. + + BUILD CHANGES: + + - Handle an operating system that use mkdev() in place of makedev(). - * 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.
