-NEWS for rsync 2.6.4 (UNRELEASED)
-Protocol: 29 (changed)
-Changes since 2.6.3:
+NEWS for rsync 2.6.9 (unreleased)
+Protocol: 29 (unchanged)
+Changes since 2.6.8:
- 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 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.
-
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 the cygwin's 2.6.3 rsync package.)
+ - 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 a potential hang when verbosity is high, the client side is
- the sender, and the file-list is large.
+ - 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.
- - 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.
+ - 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 an off-by-one error in the handling of --max-delete=N.
+ - 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.
- - One place in the code wasn't checking if fork() failed.
+ - 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).
- - The "ignore nonreadable" daemon parameter used to erroneously affect
- symlinks that pointed to a non-existent file. This has been fixed.
+ - If the receiving side fails to create a directory, it will now skip
+ trying to update everything that is inside that directory.
- - 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.
+ - 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 generator now properly runs the hard-link loop and the dir-time
- rewriting loop after we're sure that the redo phase is complete.
+ - 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).
- - 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.
+ - 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.
- - One call to flush_write_file() was not being checked for an error.
+ - 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).
- - The --no-relative option was not being sent from the client to a
- server sender.
+ - Fixed a recent bug where --delete was not working when transferring from
+ the root (/) of the filesystem with --relative enabled.
- - 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 recent bug where an --exclude='*' could affect the root (/) of
+ the filesystem with --relative enabled.
- - 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 to decompress the data
- properly, and thus the transferred file would fail its verification.
+ - 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 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).
+ - 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.
- - 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.)
+ - Fixed a bug in the daemon's "incoming chmod" rule: newly-created
+ directories no longer get the 'F' (file) rules applied to them.
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. This makes it more efficient than the
- default, before-the-transfer behavior, which is now available as
- --delete-before (that 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.
-
- - 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).
+ - 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.
- - 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".)
+ - 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.)
- - 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.
+ - Made "log file" and "syslog facility" settable on a per-module basis in
+ the daemon's config file.
- - 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).
+ - 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.)
- - 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.
+ - 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 if the pre-xfer
+ command wants to cache some arg/request info for the post-xfer command.
- - 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.
