	1	NEWS for rsync 2.6.3 (UNRELEASED)
	2	Protocol: 28 (unchanged)
	3	Changes since 2.6.2:
	4
	5	BUG FIXES:
	6
	7	- Fixed a crash bug that might appear when --delete was used and
	8	multiple source directories were specified.
	9
	10	- Fixed the 32-bit truncation of the file length when generating the
	11	checksums.
	12
	13	- The --backup code no longer attempts to create some directories
	14	over and over again (generating warnings along the way).
	15
	16	- Fixed a bug in the reading of the secrets file (by the daemon) and
	17	the password file (by the client): the files no longer need to be
	18	terminated by a newline for their content to be read in.
	19
	20	- If a file has a read error on the sending side or the reconstructed
	21	data doesn't match the expected checksum (perhaps due to the basis
	22	file changing during the transfer), the receiver will no longer
	23	retain the resulting file unless the --partial option was specified.
	24	(Note: for the read-error detection to work, neither side can be
	25	older than 2.6.3 -- older receivers will always retain the file, and
	26	older senders don't tell the receiver that the file had a read
	27	error.)
	28
	29	- If a file gets resent in a single transfer and the --backup option
	30	is enabled, rsync no longer performs a duplicate backup (losing the
	31	original file in the process).
	32
	33	- Fixed an age-old crash problem with --read-batch on a local copy
	34	(rsync was improperly assuming --whole-file for the local copy).
	35
	36	- Files specified in the daemon's "exclude" or "exclude from" config
	37	items are now excluded from being uploaded (assuming that the module
	38	allows uploading at all) in addition to the old download exclusion.
	39
	40	- Got rid of a potential hang in the receiver when near the end of a
	41	phase.
	42
	43	- When using --backup without a --backup-dir, rsync no longer preserves
	44	the modify time on directories. This avoids confusing NFS.
	45
	46	- When --copy-links (-L) is specified, we now output a separate error
	47	for a symlink that has no referent instead of claiming that a file
	48	"vanished".
	49
	50	- Error messages from the daemon server's option-parsing (such as
	51	refused options) now get sent back to the client (the server used
	52	to just exit because the socket wasn't in the right state to send
	53	the message).
	54
	55	- Most errors that occur during a daemon transfer are now returned to
	56	the user in addition to being logged (some messages are intended to
	57	be daemon-only).
	58
	59	- Fixed a bug in the daemon authentication code when using one of the
	60	batch-processing options.
	61
	62	- We try to work around some buggy IPv6 implementations that fail to
	63	implement IPV6_V6ONLY. This should fix the "address in use" error
	64	that some daemons get when running on an OS with a buggy IPv6
	65	implementation. Also, if the new code gets this error, we might
	66	suggest that the user specify --ipv4 or --ipv6 (if we think it will
	67	help).
	68
	69	- When the remote rsync dies, make a better effort to recover any error
	70	messages it may have sent instead of just dying with a write error
	71	trying to send data over the socket.
	72
	73	- When using --delete and a --backup-dir that contains files that are
	74	hard-linked to their destination equivalents, rsync now makes sure
	75	that removed files really get removed (works around a really weird
	76	rename() behavior).
	77
	78	- Avoid a bogus run-time complaint about a lack of 64-bit integers when
	79	the int64 type is defined as an off_t and it actually has 64-bits.
	80
	81	ENHANCEMENTS:
	82
	83	- Added the --partial-dir=DIR option that lets you specify where to
	84	(temporarily) put a partially transferred file (instead of over-
	85	writing the destination file). E.g. --partial-dir=.rsync-partial
	86
	87	- Added --keep-dirlinks (-K), which allows you to symlink a directory
	88	onto another partition on the receiving side and have rsync treat it
	89	as matching a normal directory from the sender.
	90
	91	- Added the --inplace option that tells rsync to write each destination
	92	file without using a temporary file. The matching of existing data
	93	in the destination file can be severely limited by this, but there
	94	are also cases where this is more efficient (such as appending data).
	95	Use only when needed (see the man page for more details).
	96
	97	- Added the "write only" option to the daemon's config file.
	98
	99	- Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
	100	and documented all these options in the man page.
	101
	102	- Improved the handling of the --bwlimit option so that it's less
	103	bursty, more accurate, and works properly over a larger range of
	104	values.
	105
	106	- The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
	107	SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
	108
	109	- Added the --checksum-seed=N option for advanced users.
	110
	111	- Batch writing/reading has a brand-new implementation that is simpler,
	112	fixes a few weird problems with the old code (such as no longer
	113	sprinkling the batch files into different dirs or even onto different
	114	systems), and is much less intrusive into the code (making it easier
	115	to maintain for the future). The new code generates just one data
	116	file instead of three, which makes it possible to read the batch via
	117	stdin. Also, the old requirement of using the same fixed checksum-
	118	seed for all batch processing has been removed.
	119
	120	- If an rsync daemon has a module set with "list = no" (which hides its
	121	presence in the list of available modules), a user that fails to
	122	authenticate gets the same "unknown module" error that they would get
	123	if the module were actually unknown (while still logging the real
	124	error to the daemon's log file). This prevents fishing for modules
	125	names.
	126
	127	INTERNAL:
	128
	129	- Some cleanup in the exclude code has saved some per-exclude memory
	130	and made the code easier to maintain.
	131
	132	- Improved the argv-overflow checking for a remote command that has
	133	a lot of args.
	134
	135	- Use rsyserr() in the various places that were still calling
	136	rprintf() with strerror() as an arg.
	137
	138	- If an rsync daemon is listening on multiple sockets (to handle both
	139	IPv4 and IPv6 to a single port), we now close all the unneeded file
	140	handles after we accept a connection (we used to close just one of
	141	them).
	142
	143	- Optimized the handling of larger block sizes (rsync used to slow to
	144	a crawl if the block size got too large). Also cap the block size.
	145
	146	- Optimized away a loop in hash_search().
	147
	148	- Make sure that a filename that contains a newline gets mentioned with
	149	each newline transformed into a question mark (which makes parsing
	150	the verbose output via script more dependable).
	151
	152	BUILD CHANGES:
	153
	154	- Added a "gen" target to rebuild most of the generated files,
	155	including configure, config.h.in, the man pages, and proto.h.
	156
	157	- If "make proto" doesn't find some changes in the prototypes, the
	158	proto.h file is left untouched (its time-stamp used to always be
	159	updated).
	160
	161	- The variable $STRIP (that is optionally set by the install-strip
	162	target's rule) was changed to $INSTALL_STRIP because some systems
	163	have $STRIP set in the environment.
	164
	165	- Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
	166
	167	DEVELOPER RELATED:
	168
	169	- The scripts in the testsuite dir were cleaned up a bit.
	170
	171	- Some new diffs were added to the patches dir, and some accepted
	172	ones were removed.
