+NEWS for rsync 3.0.0 (UNRELEASED)
+Protocol: 30 (changed)
+Changes since 2.6.9:
BUG FIXES:
- - Fixed a crash bug that might appear when --delete was used and
- multiple source directories were specified.
+ - Fixed the output of -ii when combined with one of the --*-dest options:
+ it now itemizes all the items, not just the changed ones.
- - Fixed the 32-bit truncation of the file length when generating the
- checksums.
+ - 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.
- - The --backup code no longer attempts to create some directories
- over and over again (generating warnings along the way).
+ - 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.
- - Fixed a bug in the reading of the secrets file (by the daemon) and
- the password file (by the client): the files no longer need to be
- terminated by a newline for their content to be read in.
+ - A negated filter rule now sends the negation option when sending the
+ filter rules.
- - If a file has a read error on the sending side, the receiver will
- no longer keep the resulting file unless the --partial option was
- specified. (Note: both sides must be running 2.6.3 for this to
- work -- older receivers always keep the file, and older senders
- don't tell the receiver that the file was not read correctly.)
+ - Fixed a problem with the --out-format (aka --log-format) option: it
+ would output superfluous directory information for a non-daemon rsync.
- - If a file gets resent in a single transfer and the --backup option
- is enabled, rsync no longer performs a duplicate backup (losing the
- original file in the process).
+ - 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.
- - Fixed an age-old crash problem with --read-batch on a local copy
- (rsync was improperly assuming --whole-file for the local copy).
+ - 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.
- - Files specified in the daemon's "exclude" or "exclude from" config
- items are now excluded from being uploaded (assuming that the module
- allows uploading at all) in addition to the old download exclusion.
+ - Make sure that directory permissions of a newly-created destination
+ directory are handled right when --perms is left off.
- - Got rid of a potential hang in the receiver when near the end of a
- phase.
-
- - When using --backup without a --backup-dir, rsync no longer preserves
- the modify time on directories. This avoids confusing NFS.
-
- - When --copy-links (-L) is specified, we now output a separate error
- for a symlink that has no referent instead of claiming that a file
- "vanished".
-
- - Error messages from the daemon server's option-parsing (such as
- refused options) now get sent back to the client (the server used
- to just exit because the socket wasn't in the right state to send
- the message).
-
- - Most errors that occur during a daemon transfer are now returned to
- the user in addition to being logged (some messages are intended to
- be daemon-only).
-
- - Fixed a bug in the daemon authentication code when using one of the
- batch-processing options.
-
- - We try to work around some buggy IPv6 implementations that fail to
- implement IPV6_V6ONLY. This should fix the "address in use" error
- that some daemons get when running on an OS with a buggy IPv6
- implementation. Also, if the new code gets this error, we might
- suggest that the user specify --ipv4 or --ipv6 (if we think it will
- help).
+ - Improved --hard-link so that more corner cases are handled correctly
+ when combined with options such as --link-dest and/or --ignore-existing.
ENHANCEMENTS:
- - Added --keep-dirlinks (-K), which allows you to symlink a directory
- onto another partition on the receiving side and have rsync treat it
- as matching a normal directory from the sender.
-
- - Added the "write only" option to the daemon's config file.
-
- - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
- and documented all these options in the man page.
-
- - Improved the handling of the --bwlimit option so that it's less
- bursty, more accurate, and works properly over a larger range of
- values.
-
- - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
- SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
-
- - Added the --checksum-seed=N option for advanced users.
-
- - Batch writing/reading has a brand-new implementation that is
- simpler, fixes a few weird problems with the old code, and is much
- less intrusive into the code (making it easier to maintain for the
- future). (Chris Shoemaker)
+ - 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.
INTERNAL:
- - Some cleanup in the exclude code has saved some per-exclude memory
- and made the code easier to maintain.
+ - 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.
- - Improved the argv-overflow checking for a remote command that has
- a lot of args.
+ - Rsync now supports the transfer of 64-bit timestamps (time_t values).
- - Use rsyserr() in the various places that were still calling
- rprintf() with strerror() as an arg.
+ - Fixed a build problem with older (2.x) versions of gcc.
- - If an rsync daemon is listening on multiple sockets (to handle both
- IPv4 and IPv6 to a single port), we now close all the unneeded file
- handles after we accept a connection (we used to close just one of
- them).
+ - Added some isType() functions that make dealing with signed characters
+ easier without forcing variables via casts.
- - Optimized away a loop in hash_search().
+ - Upgraded the included popt version to 1.10.2 and improved its use of
+ string-handling functions.
- BUILD CHANGES:
+ - Added missing prototypes for compatibility functions from the lib dir.
- - Added a "gen" target to rebuild most of the generated files,
- including configure, config.h.in, the man pages, and proto.h.
+ - Configure determines if iconv() has a const arg, allowing us to avoid a
+ compiler warning.
- - If "make proto" doesn't find some changes in the prototypes, the
- proto.h file is left untouched (its time-stamp used to always be
- updated).
+ - Made the sending of some numbers more efficient for protocol 30.
- - The variable $STRIP (that is optionally set by the install-strip
- target's rule) was changed to $INSTALL_STRIP because some systems
- have $STRIP set in the environment.
+ - Make sure that a daemon process doesn't mind if the client was weird and
+ omitted the --server option.
- - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
+ - Improved the use of "const" on pointers.
- DEVELOPER RELATED:
+ - Improved J.W.'s pool_alloc routines to add a way of freeing older
+ sections of a pool's memory.
- - The scripts in the testsuite dir were cleaned up a bit.
+ DEVELOPER RELATED:
- - Some new diffs were added to the patches dir, and some accepted
- ones were removed.
+ - Rsync is now licensed under the GPLv3 or later.
+ - 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).
