+NEWS for rsync 2.6.7 (UNRELEASED)
+Protocol: 29 (unchanged)
+Changes since 2.6.6:
- 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) value 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.
+ - Fixed a really old bug that caused --checksum (-c) to checksum all the
+ files encountered during the delete scan (ouch).
- - Avoid a mkdir warning when removing a directory in the destination
- that already exists in the --backup-dir.
+ - Made hard-links work with symlinks and devices again.
- - 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 2.6.3 rsync package.)
+ - If a device-file/special-file changes permissions, rsync now updates the
+ permissions without recreating the file.
- - Fixed a potential hang when verbosity is high, the client side is
- the sender, and the file-list is large.
+ - 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.
- - 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 --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.
- - Fixed an off-by-one error in the handling of --max-delete=N.
+ - Reject the combination of --inplace and --sparse since the sparse-output
+ algorithm doesn't work when overwriting existing data.
- - One place in the code wasn't checking if fork() failed.
+ - Fixed the directory name in the error that is output when pop_dir()
+ fails.
- - The "ignore nonreadable" daemon parameter used to erroneously affect
- symlinks that pointed to a non-existent file. This has been fixed.
+ - Really fixed the parsing of a "!" entry in .cvsignore files this time.
- - 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.
+ - 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).
- - 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.
+ - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
+ the exit status properly and generate a better error.
- - 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 some glitches in the double-verbose output when using --copy-dest,
+ --link-dest, or --compare-dest.
- - One call to flush_write_file() was not being checked for an error.
+ ENHANCEMENTS:
- - The --no-relative option was not being sent from the client to a
- server sender.
+ - Added the --append option that makes rsync append data onto files
+ that are longer on the source than the destination (this includes new
+ files).
- - 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).
+ - Added the --min-size=SIZE option to exclude small files from the
+ transfer.
- - 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).
+ - Added the --compress-level option to allow you to set how aggressive
+ rsync's compression should be (this option implies --compress).
- - 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).
+ - 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).
- ENHANCEMENTS:
+ - The options --human-readable (-h) and --si change the output of the
+ --stats and the end-of-run summary to be easier to read.
- - 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 (this is 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 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 (e.g. 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
- 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.
-
- - 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.
+ - If lutimes() and/or lchmod() are around, use them to allow the
+ preservation of attributes on symlinks.
- INTERNAL:
+ - The --link-dest option now affects symlinks and devices (when
+ possible).
- - Added better checking of the checksum-header values that come over
- the socket.
+ - Improved the output of hard-linked and copied files when using
+ --link-dest, --copy-dest, or --compare-dest.
- - Merged a variety of file-deleting functions into a single function so
- that it is easier to maintain.
+ - 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 manpage for a list of the environment variables
+ that are set with information about the transfer.)
- - Improved the type of some variables (particularly blocksize vars) for
- consistency and proper size.
+ - 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).
- - Got rid of the uint64 type (which we didn't need).
+ - 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.
- - Use a slightly more compatible set of core #include directives.
+ - Added the --chmod=MODE option that allows the destination permissions
+ to be changed from the source permissions. E.g. --chmod=g+w,o-rwx
- - Defined int32 in a way that ensures that the build dies if we can't
- find a variable with at least 32 bits.
+ - Allow the --temp-dir option to be specified when starting a daemon,
+ which sets the default temporary directory for incoming files.
- - 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.
+ - If --delete is combined with --dirs without --recursive, rsync will
+ now delete in any directory whose content is being synchronized.
- PROTOCOL DIFFERENCES FOR VERSION 29:
+ - 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.
- - 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 (resorting to the old-style outputting
- of local change-messages for older protocols).
+ - 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 transferred
+ file #5, and we still need to check 8383 files out of 9999 total.
- - If --inplace is specified, the generator sends an extra byte after
- the flag-word indicating what kind of basis file is being used for
- the transfer (see the FNAMECMP_* defines). This information is used
- to optimize the transfer when the basis file is not the destination.
+ - Some minor documentation improvements.
- - 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).
+ - Updated some diffs in the patches dir.
- - 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".)
+ INTERNAL:
- - 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 encluded in the options sent over the
- socket.
+ - Some buffer sizes were expanded a bit, particularly on systems where
+ MAXPATHLEN is overly small (e.g. cygwin).
- - 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).
+ - If io_printf() tries to format more data than fits in the buffer, exit
+ with an error instead of transmitting a truncated buffer.
- - When --delete-excluded is specified with some filter rules (AKA
- 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.
+ - If a va_copy macro is defined, lib/snprintf.c will use it when defining
+ the VA_COPY macro.
- - 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.
+ - Reduced the amount of stack memory needed for each level of directory
+ recursion by nearly MAXPATHLEN bytes.
- BUILD CHANGES:
+ DEVELOPER RELATED:
- - Handle an operating system that use mkdev() in place of makedev().
+ - 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.
- - Improved configure to better handle cross-compiling.
