NEWS for rsync 2.6.1 (UNRELEASED)
Protocol: 27 (unchanged)
Changes since 2.6.0:
ENHANCEMENTS:
* Lower memory use and more optimal transfer of data over
the socket (see the INTERNAL section for details).
* The RSYNC_PROXY environment variable can now contain a
"USER:PASS@" prefix before the "HOST:PORT" information.
(Bardur Arantsson)
* The --progress output now mentions how far along in the
transfer we are, including both a count of files transferred
and a percentage of the total file-count that we're processed.
BUG FIXES:
* The --link-dest code now works properly for a non-root user
when the UIDs of the source and destination differ and -u was
specified, and when the group of the source can't be used on
the destination and -g was specified. (Wayne Davison)
* Fixed a bug in the handling of -H (hard-links) that might
cause the expanded PATH/NAME value of the current item to
get overwritten (due to an expanded-name caching bug).
(Wayne Davison)
* Keep per-file track of the sending of literal data with
--partial so that an interrupted transfer doesn't keep a
shorter temp file when no new data has been transfered over
the wire. (Wayne Davison)
* Fixed a byte-order problem in --batch-mode on big-endian
machines. (Jay Fenlason)
* Fixed configure bug when running "./configure --disable-ipv6".
(Wayne Davison)
* Fixed "make test" bug when build dir is not the source dir.
* When using --cvs-exclude, the exclude items we get from a
directory's .cvsignore file once again only affect that one
directory (and not all following directories too).
* When transferring a file that has group 0 with -g specified
(typically via -a) and not enough privs to retain the group,
rsync no longer complains about chown failing.
* When specifying the USER@HOST: prefix for a file, the USER
part can now contain an '@', if needed (i.e. the last '@'
is used to find the HOST, not the first).
INTERNAL:
* Most of the I/O is now buffered, which results in a pretty
large speedup when running under MS Windows. (Craig Barratt)
* Optimizations to the name-handling/comparing code have made
some significant reductions in user-CPU time for large file
sets. (Wayne Davison)
* Some variable-type cleanup that makes the code more consistent.
(Wayne Davison)
* Reduced memory requirements of hard link preservation.
(J.W. Schultz)
* Implemented a new algorithm for hard-link handling that speeds
up the code significantly. (J.W. Schultz and Wayne Davison)
* Got rid of support for protocol versions 17 and 18 (which are
both over 6 years old). (Wayne Davison)
* More optimal data transmission for --hard-links (protocol 28).
* More optimal data transmission for --checksum (protocol 28).
* Less memory used for holding --checksum data.
* Less memory used per-file in the file list.
* The 2 pipes used between the receiver and generator processes
(which are forked on the same machine) were reduced to 1 pipe
and the protocol improved so that (1) it is now impossible to
have the "redo" pipe fill up and hang rsync, and (2) trailing
messages from the receiver don't get lost on their way through
the generator over to the sender (the latter mainly affected
hard-link messages). (Wayne Davison)
* The reading & writing of the file list in batch-mode is now
handled by the same code that sends & receives the list over
the wire. This makes it much easier to maintain.
NEWS for rsync 2.6.0 (1 Jan 2004)
Protocol: 27 (changed)
Changes since 2.5.7:
ENHANCEMENTS:
* "ssh" is now the default remote shell for rsync. If you want to
change this, configure like this: "./configure --with-rsh=rsh".
* Added --files-from, --no-relative, --no-implied-dirs, and --from0.
Note that --from0 affects the line-ending character for all the
files read by the --*-from options. (Wayne Davison)
* Length of csum2 is now per-file starting with protocol version
27. (J.W. Schultz)
* Per-file dynamic block size is now sqrt(file length). The
per-file checksum size is determined according to an algorithm
provided by Donovan Baarda which reduces the probability of rsync
algorithm corrupting data and falling back using the whole md4
checksums. (J.W. Schultz, Donovan Baarda)
* The --stats option no longer includes the (debug) malloc summary
unless the verbose option was specified at least twice.
* Added a new error/warning code for when files vanish from the
sending side. Made vanished source files not interfere with the
file-deletion pass when --delete-after was specified.
* Various trailing-info sections are now preceded by a newline.
BUG FIXES:
* Fixed several exclude/include matching bugs when using wild-cards.
This has a several user-visible effects, all of which make the
matching more consistent and intuitive. This should hopefully not
cause anyone problems since it makes the matching work more like
what people are expecting. (Wayne Davison)
- A pattern with a "**" no longer causes a "*" to match slashes.
For example, with "/*/foo/**", "foo" must be 2 levels deep.
[If your string has BOTH "*" and "**" wildcards, changing the
"*" wildcards to "**" will provide the old behavior in all
versions.]
- "**/foo" now matches at the base of the transfer (like /foo
does). [Use "/**/foo" to get the old behavior in all versions.]
- A non-anchored wildcard term floats to match beyond the base of
the transfer. E.g. "CVS/R*" matches at the end of the path,
just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
to get the old behavior in all versions.]
- Including a "**" in the match term causes it to be matched
against the entire path, not just the name portion, even if
there aren't any interior slashes in the term. E.g. "foo**bar"
would exclude "/path/foo-bar" (just like before) as well as
"/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
old behavior in all versions.]
* The exclude list specified in the daemon's config file is now
properly applied to the pulled items no matter how deep the
user's file-args are in the source tree. (Wayne Davison)
* For protocol version >= 27, mdfour_tail() is called when the
block size (including checksum_seed) is a multiple of 64.
Previously it was not called, giving the wrong MD4 checksum.
(Craig Barratt)
* For protocol version >= 27, a 64 bit bit counter is used in
mdfour.c as required by the RFC. Previously only a 32 bit bit
counter was used, causing incorrect MD4 file checksums for
file sizes >= 512MB - 4. (Craig Barratt)
* Fixed a crash bug when interacting with older rsync versions and
multiple files of the same name are destined for the same dir.
(Wayne Davison)
* Keep tmp names from overflowing MAXPATHLEN.
* Make --link-dest honor the absence of -p, -o, and -g.
* Made rsync treat a trailing slash in the destination in a more
consistent manner.
* Fixed file I/O error detection. (John Van Essen)
* Fixed bogus "malformed address {hostname}" message in rsyncd log
when checking IP address against hostnames from "hosts allow"
and "hosts deny" parameters in config file.
* Print heap statistics when verbose >= 2 instead of when >= 1.
* Fixed a compression (-z) bug when syncing a mostly-matching file
that contains already-compressed data. (Yasuoka Masahiko and
Wayne Davison)
* Fixed a bug in the --backup code that could cause deleted files
to not get backed up.
* When the backup code makes new directories, create them with mode
0700 instead of 0755 (since the directory permissions in the
backup tree are not yet copied from the main tree).
* Call setgroups() in a more portable manner.
* Improved file-related error messages to better indicate exactly
what pathname failed. (Wayne Davison)
* Fixed some bugs in the handling of --delete and --exclude when
using the --relative (-R) option. (Wayne Davison)
* Fixed bug that prevented regular files from replacing
special files and caused a directory in --link-dest or
--compare-dest to block the creation of a file with the
same path. A directory still cannot be replaced by a
regular file unless --delete specified. (J.W. Schultz)
* Detect and report when open or opendir succeed but read and
readdir fail caused by network filesystem issues and truncated
files. (David Norwood, Michael Brown, J.W. Schultz)
* Added a fix that should give ssh time to restore the tty settings
if the user presses Ctrl-C at an ssh password prompt.
INTERNAL:
* Eliminated vestigial support for old versions that we stopped
supporting. (J.W. Schultz)
* Simplified some of the option-parsing code. (Wayne Davison)
* Some cleanup made to the exclude code, as well as some new
defines added to enhance readability. (Wayne Davison)
* Changed the protocol-version code so that it can interact at a
lower protocol level than the maximum supported by both sides.
Added an undocumented option, --protocol=N, to force the value
we advertise to the other side (primarily for testing purposes).
