+NEWS for rsync 3.0.0 (UNRELEASED)
+Protocol: 30 (changed)
+Changes since 2.6.9:
- 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).
-
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 --dry-run option (-n) now mentions changes in directories (w/-v).
- It also now includes the normal uptodate output information for -vv.
-
- - Avoid a mkdir warning when removing a directory in the destination
- that already exists in the --backup-dir.
+ - Fixed the output of -ii when combined with one of the --*-dest options:
+ it now itemizes all the items, not just the changed ones.
- - 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.)
+ - Made the output of all file types consistent when using a --*-dest
+ option. Prior versions used to output too many creation events for
+ matching items.
- - Fixed a potential hang when verbosity is high, the client side is
- the sender, and the file-list is large.
+ - The code that waits for a child pid now handles being interrupted by a
+ signal. This fixes a problem with the pre-xfer exec function not being
+ able to get the exit status from the script.
- - 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.
+ - A negated filter rule now sends the negation option when sending the
+ filter rules.
- - Fixed an off-by-one error in the handling of --max-delete=N.
+ - Fixed a problem with the --out-format (aka --log-format) option: it
+ would output superfluous directory information for a non-daemon rsync.
- - One place in the code wasn't checking if fork() failed.
+ - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
+ files (which includes local copies). Version 2.6.9 would complete the
+ copy, but exit with an error when the receiver output its memory stats.
- - The "ignore nonreadable" daemon parameter no longer affects symlinks
- that are being copied, even if they point nowhere.
+ - If --password-file is used on a non-daemon transfer, rsync now complains
+ and exits. This should help users figure out that they can't use this
+ option to control a remote shell's password prompt.
- - 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.
+ - Make sure that directory permissions of a newly-created destination
+ directory are handled right when --perms is left off.
- - 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.
+ - Improved --hard-link so that more corner cases are handled correctly
+ when combined with options such as --link-dest and/or --ignore-existing.
- - 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.
+ ENHANCEMENTS:
- - One call to flush_write_file() was not being checked for an error.
+ - A new incremental-recursion algorithm is now used when rsync is talking
+ to another 3.0.0 version. This starts the transfer going more quickly
+ (before all the files have been found), and requires much less memory.
+ See the --recursive option in the manpage for some restrictions.
+
+ - The default --delete algorithm is now --delete-during when talking to a
+ 3.x rsync. This is a faster scan than using --delete-before (which is
+ the default when talking to older rsync versions), and is compatible with
+ the new incremental recursion mode.
+
+ - Added the --delete-delay option, which is a more efficient way to delete
+ files at the end of the transfer without needing a separate delete pass.
+
+ - Added the --acls (-A) option to preserve Access Control Lists. This is
+ an improved version of the prior patch that was available. (If you need
+ to have backward compatibility with old, patched versions, the new
+ acls.diff patch that will add that.)
+
+ - Added the --xattrs (-X) option to preserver extended attributes. This is
+ an improved version of the prior patch that was available. (If you need
+ to have backward compatibility with old, patched versions, the new
+ xattrs.diff patch that will add that.)
+
+ - Added the --fake-super option that allows a non-super user to preserve
+ all attributes of a file by using a special extended-attribute idiom.
+ There is also an analogous "fake super" option for an rsync daemon.
+
+ - Added the --iconv option, which allows rsync to convert filenames from
+ one character-set to another during the transfer. The default is to make
+ this feature available as long as your system has iconv_open(). If
+ compilation fails, specify --disable-iconv to configure and rebuild. If
+ you want rsync to perform character-set conversions by default, you can
+ specify --enable-iconv=CONVERT_STRING with the default value for the
+ --iconv option that you wish to use. For example, --enable-iconv=. is a
+ good choice. See the rsync man page for an explanation of the --iconv
+ option's settings.
+
+ - Added the --skip-compress=LIST option to override of the default list of
+ file suffixes that will not be compressed when using --compress.
+
+ - The --max-delete option now outputs a warning if it skipped any file
+ deletions, including a count of how many deletions were skipped. (Older
+ versions just silently stopped deleting things.)
+
+ - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
+ about any files that it wants to delete without deleting anything. If
+ you're not sure what version the client is, you can use the less-obvious
+ --max-delete=-1, as old and new versions will both treat that as the
+ same request (though older versions don't warn).
+
+ - The --hard-link option now uses less memory on both the sending and
+ receiving side for all protocol versions. For protocol 30, the use of a
+ hashtable on the sending side allows us to more efficiently convey to the
+ receiver what files are linked together. This reduces the amount of data
+ sent over the socket by a considerable margin (rather than adding more
+ data), and limits the in-memory storage of the device+inode information
+ to just the sending side for the new protocol 30, or to the receiving
+ side when speaking an older protocol (note that older rsync versions kept
+ the device+inode information on both sides).
+
+ - A lot more --no-OPTION override options are now supported.
- - The --no-relative option was not being sent from the client to a
- server sender.
+ INTERNAL:
- - 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).
+ - The file-list sorting algorithm now uses a sort that keeps any same-
+ named items in the same order as they were specified. This allows
+ rsync to always ensure that the first of the duplicates is the one
+ that will be included in the copy. The new sort was also faster
+ than the glibc version of qsort() and mergesort() in my testing.
- - 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).
+ - Rsync now supports the transfer of 64-bit timestamps (time_t values).
- ENHANCEMENTS:
+ - Fixed a build problem with older (2.x) versions of gcc.
- - 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 behavior is also explicitly selectable via --delete-before.
-
- - 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".
-
- - 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.
-
- - 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.
-
- - 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.
-
- - 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.)
-
- 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.
+ - Added some isType() functions that make dealing with signed characters
+ easier without forcing variables via casts.
- INTERNAL:
+ - Upgraded the included popt version to 1.10.2 and improved its use of
+ string-handling functions.
- - Added better checking of the checksum-header values that come over
- the socket.
+ - Added missing prototypes for compatibility functions from the lib dir.
- - Merged the various delete-file functions into a single function so
- that it is easier to maintain.
+ - Configure determines if iconv() has a const arg, allowing us to avoid a
+ compiler warning.
- - Improved the type of some variables (particularly blocksize vars) for
- consistency and proper size.
+ - Made the sending of some numbers more efficient for protocol 30.
- - Got rid of the uint64 type (which we didn't need).
+ - Make sure that a daemon process doesn't mind if the client was weird and
+ omitted the --server option.
- - Use a slightly more compatible set of core #include directives.
+ - Improved the use of "const" on pointers.
- - Defined int32 in a way that ensures that the build dies if we can't
- find a variable with at least 32 bits.
+ - Improved J.W.'s pool_alloc routines to add a way of freeing older
+ sections of a pool's memory.
- BUILD CHANGES:
+ DEVELOPER RELATED:
- - Handle an operating system that use mkdev() in place of makedev().
+ - Rsync is now licensed under the GPLv3 or later.
- - Improved configure to better handle cross-compiling.
+ - Rsync now has a way of handling protocol-version changes during the
+ development of a new protocol version. This exchange of sub-version
+ info does not interfere with the {MIN,MAX}_PROTOCOL_VERSION checking
+ in older versions (which would be the case if every minor change made
+ to the protocol in CVS incremented the main PROTOCOL_VERSION value).
