- * Don't report an error if an excluded file disappears during an
- rsync run. (Eugene Chupriyanov and Bo Kersey)
-
- * Added .svn to --cvs-exclude list to support subversion. (Jon
- Middleton)
-
- * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
- and "hosts deny" fields. (Hideaki Yoshifuji)
-
- * Changed exclude file handling to permit DOS or MAC style line
- terminations. (J.W. Schultz)
-
- * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
- (Dave Dykstra)
-
- BUG FIXES:
-
- * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
- L. Allen, Martin Pool)
-
- * Generate each file's rolling-checksum data as we send it, not
- in a separate (memory-eating) pass before hand. This prevents
- timeout errors on really large files. (Stefan Nehlsen)
-
- * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
-
- * Better handling of some client-server errors. (Martin Pool)
-
- * Fixed a crash that would occur when sending a list of files that
- contains a duplicate name (if it sorts to the end of the file
- list) and using --delete. (Wayne Davison)
-
- * Fixed the file-name duplicate-removal code when dealing with multiple
- dups in a row. (Wayne Davison)
-
- * Fixed a bug that caused rsync to lose the exit status of its child
- processes and sometimes return an exit code of 0 instead of showing
- an error. (David R. Staples, Dave Dykstra)
-
- * Fixed bug in --copy-unsafe-links that caused it to be completely
- broken. (Dave Dykstra)
-
- * Prevent infinite recursion in cleanup code under certain circumstances.
- (Sviatoslav Sviridov and Marc Espie)
-
- * Fixed a bug that prevented rsync from creating intervening directories
- when --relative-paths/-R is set. (Craig Barratt)
-
- * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
-
- INTERNAL:
-
- * Many code cleanups and improved internal documentation. (Martin
- Pool, Nelson Beebe)
-
- * Portability fixes. (Dave Dykstra and Wayne Davison)
-
- * More test cases. (Martin Pool)
-
- * Some test-case fixes. (Brian Poole, Wayne Davison)
-
- * Updated included popt to the latest vendor drop, version 1.6.4.
- (Jos Backus)
-
- * Updated config.guess and config.sub to latest versions; this
- means rsync should build on more platforms. (Paul Green)
+ * Implemented a new algorithm for hard-link handling that speeds
+ up the code significantly. (J.W. Schultz and Wayne Davison)
+
+ * The --hard-link option now uses the first existing file in the
+ group of linked files as the basis for the transfer. This
+ prevents the sub-optimal transfer of a file's data when a new
+ hardlink is added on the sending side and it sorts alphabetically
+ earlier in the list than the files that are already present on the
+ receiving side.
+
+ * Dropped support for protocol versions less than 20
+ (2.3.0 released 15 Mar 1999) and activated warnings for
+ protocols less than 25 (2.5.0 released 23 Aug 2001)
+ (Wayne Davison and J.W. Schultz, severally)
+
+ * More optimal data transmission for --hard-links (protocol 28).
+
+ * More optimal data transmission for --checksum (protocol 28).
+
+ * Less memory is used when --checksum is specified.
+
+ * Less memory is used in the file list (a per-file savings).
+
+ * The generator is now better about not modifying the file list
+ during the transfer in order to avoid a copy-on-write memory
+ bifurcation (on systems where fork() uses shared memory).
+ Previously, rsync's shared memory would slowly become unshared,
+ resulting in real memory usage nearly doubling on the receiving
+ side by the end of the transfer. Now, as long as permissions
+ are being preserved, the shared memory should remain that way
+ for the entire transfer.
+
+ * Changed hardlink info and file_struct + strings to use
+ allocation pools. This reduces memory use for large file-
+ sets and permits freeing memory to the OS. (J.W. Schultz)
+
+ * 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 and verbose --stats output).
+
+ * 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.
+
+ * Improved the internal uid/gid code to be more portable and
+ a little more optimized.
+
+ * Device numbers are now sent as separate major/minor values
+ with 32-bit accuracy for each one (protocol 28). Previously
+ hard-link device data was sent as a single 64-bit number, and
+ copied devices were sent as a single 32-bit number. This will
+ make inter-operation of 64-bit binaries more compatible with
+ their 32-bit brethren. Note that optimizations in the binary
+ protocol often sends the device data using fewer bytes than
+ before, even though more precision is now available.
