1 NEWS for rsync 2.6.4 (UNRELEASED)
7 - When rsync deletes a directory and outputs a verbose message about
8 it, it now appends a trailing slash to the name instead of (only
9 sometimes) outputting a preceding "directory " string.
11 - The --stats output will contain file-list time-statistics if both
12 sides are 2.6.4, or if the local side is 2.6.4 and the files are
13 being pushed (since the stats come from the sending side).
14 (Requires protocol 29 for a pull.)
16 - The "%o" (operation) value now has a third value besides "send" and
17 "recv": "del." (with trailing dot to make it 4 chars). This changes
18 the way deletions are logged in the daemon's log file.
22 - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
23 was only treating it as a special token in an rsync include/exclude
26 - The combination of --verbose and --dry-run now mentions the full list
27 of changes that would be output without --dry-run.
29 - Avoid a mkdir warning when removing a directory in the destination
30 that already exists in the --backup-dir.
32 - An OS that has a binary mode for its files (such as cygwin0 needed
33 setmode(fd, O_BINARY) called on the temp-file we opened with
34 mkstemp(). (Fix derived from the Cygwin's 2.6.3 rsync package.)
36 - Fixed a potential hang when verbosity is high, the client side is
37 the sender, and the file-list is large.
39 - We now check if the OS doesn't support using mknod() for creating
40 FIFOs and sockets, and compile-in using mkfifo() and socket() when
43 - Fixed an off-by-one error in the handling of --max-delete=N.
45 - One place in the code wasn't checking if fork() failed.
47 - The "ignore nonreadable" daemon parameter used to erroneously affect
48 symlinks that pointed to a non-existent file. This has been fixed.
50 - If the OS does not have lchown() and its chown() tries to set the
51 referent of a symlink (as it should), we no longer try to set the
52 user and group of a symlink.
54 - The generator now properly runs the hard-link loop and the dir-time
55 rewriting loop after we're sure that the redo phase is complete.
57 - When --backup was specified with --partial-dir=DIR (where DIR is a
58 relative path), the backup code was erroneously trying to backup a
59 file that was put into the partial-dir.
61 - One call to flush_write_file() was not being checked for an error.
63 - The --no-relative option was not being sent from the client to a
66 - If an rsync daemon specified "dont compress = ..." for a file and the
67 client tried to specify --compress, the libz code was not handling a
68 compression level of 0 properly. This could cause a transfer failure
69 if the block-size for a file was large enough (i.e. rsync might have
70 exited with an error for large files).
72 - Fixed a bug that would sometimes surface when using --compress and
73 sending a file with a block-size larger than 64K (either manually
74 specified, or computed due to the file being really large). Prior
75 versions of rsync would sometimes fail to to decompress the data
76 properly, and thus the transferred file would fail its verification.
78 - If a daemon can't open the specified log file (i.e. syslog is not
79 being used), die without crashing. We also output an error about
80 the failure on stderr (which will only be seen if --no-detach was
83 - A local transfer no longer duplicates all its include/exclude options
84 (since the forked process already has a copy of the exclude list,
85 there's no need to send them a set of duplicates).
89 - Rsync now supports popt's option aliases, which means that you can
90 use /etc/popt and/or ~/.popt to create your own option aliases.
92 - Added the --delete-during (--del) option which will delete files
93 from on the receiving side incrementally as each directory in the
94 transfer is being processed. This makes it more efficient than the
95 default, before-the-transfer behavior, which is now available as
96 --delete-before (this is the default --delete-WHEN option that will
97 be chosen if --delete or --delete-excluded is specified without a
98 --delete-WHEN choice). All the --del* options infer --delete, so an
99 rsync daemon that refuses "delete" will still refuse to allow any
100 file-deleting options.
102 - All the --delete-WHEN options are now more memory efficient:
103 Previously an entire duplicate set of file-list objects was created
104 on the receiving side for the entire destination hierarchy. The new
105 algorithm only creates one directory of objects at a time.
107 - Added the --copy-dest option, which works like --link-dest except
108 that it includes copies of identical files.
110 - Added support for specifying multiple --compare-dest, --copy-dest, or
111 --link-dest options, but only of a single type. (Promoted from the
112 patches dir and enhanced.)
114 - Added the --max-size option. (Promoted from the patches dir.)
116 - The daemon-mode options were separated from the normal rsync options
117 so that they can't be mixed together. This makes it impossible to
118 start a daemon that had improper default option values that could
119 cause problems (e.g. a hang or an abort) when a client connects.
121 - The --bwlimit option may now be used in combination with --daemon
122 to specify both a default value for the daemon side and a value
123 that cannot be exceeded by a user-specified --bwlimit option.
125 - Added the "port" parameter to the rsyncd.conf file. (Promoted from
126 the patches dir.) Also added "address". A command-line option
127 will take precedence over a config-file option, as expected.
129 - In _exit_cleanup(): when we are exiting with a partially-received
130 file, we now flush any data in the write-cache before closing the
133 - The --inplace support was enhanced to work with --compare-dest,
134 --link-dest, and (the new) --copy-dest options. (Requires protocol
137 - Added the --dirs (-d) option for an easier way to copy directories
140 - Added the --list-only option which is mainly a way for the client to
141 put the server into listing mode without needing to resort to any
142 internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
143 for a non-recursive listing). This option is used automatically
144 (behind the scenes) when a modern rsync speaks to a modern daemon,
145 but may also be specified manually if you want to force the use of
146 the --list-only option over a remote-shell connection.
148 - Added the --omit-dir-times (-O) option which will avoid updating the
149 modified time for directories when --times was specified. This
150 option will avoid an extra pass through the file-list at the end of
151 the transfer (to tweak all the directory times), which can result in
152 an appreciable speedup for a really large transfer. (Promoted from
155 - Added the --filter (-f) option and its helper option, -F. Filter
156 rules are an extension to the existing include/exclude handling
157 that also supports nested filter files as well as per-directory
158 filter files (like .cvsignore, but with full filter-rule parsing).
159 This new option was chosen in order to ensure that all existing
160 include/exclude processing remained 100% compatible with older
161 versions. Protocol 29 is needed for full filter-rule support, but
162 backward-compatible rules work with earlier protocol versions.
163 (Promoted from the patches dir and enhanced.)
165 - Added the --delay-updates option that puts all updated files into
166 a temporary directory (by default ".~tmp~", but settable via the
167 --partial-dir=DIR option) until the end of the transfer. This
168 makes the updates a little more atomic for a large transfer.
170 - If rsync is put into the background, any output from --progress is
173 - Documented the "max verbosity" setting for rsyncd.conf. (This
174 setting was added a couple releases ago, but left undocumented.)
176 - The sender and the generator now double-check the file-list index
177 they are given, and refuse to try to do a file transfer on a
178 non-file index (since that would indicate that something had gone
181 - Added the --itemize-changes (-i) option, which is a way to output a
182 more detailed list of what files changed in any way and how they
183 changed. The effect is the same as specifying a --log-format of
184 "%i %n%L" (see the rsyncd.conf manpage). Works with --dry-run too.
186 - Added the --fuzzy option, which attempts to find a basis file for a
187 file that is being created from scratch. The current algorithm
188 only looks in the destination directory for the created file, but
189 it does attempt to find a match based on size/mod-time (in case the
190 file was renamed with no other changes) as well as based on a fuzzy
191 name-matching algorithm. This option requires protocol 29 because
192 it needs the new file-sorting order. (Promoted from patches dir
195 - Added the --remove-sent-files option, which lets you move files
198 - Improved the option descriptions in the --help text.
202 - Added atomic-rsync to the support dir: a perl script that will
203 transfer some files using rsync, and then move the updated files into
204 place all at once at the end of the transfer. Only works when
205 pulling, and uses --link-dest and a parallel hierarchy of files to
208 - Added mnt-excl to the support dir: a perl script that takes the
209 /proc/mounts file and translates it into a set of excludes that will
210 exclude all mount points (even mapped mounts to the same disk). The
211 excludes are made relative to the specified source dir and properly
214 - Added savetransfer.c to the support dir: a C program that can make
215 a copy of all the data that flows over the wire. This lets you test
216 for data corruption (by saving the data on both the sending side and
217 the receiving side) or provides a way to help debug a protocol error.
219 - Added rrsync to the support dir: this is my version of Joe Smith's
220 restricted rsync perl script. This helps to ensure that only certain
221 rsync commands can be run by an ssh invocation.
225 - Added better checking of the checksum-header values that come over
228 - Merged a variety of file-deleting functions into a single function so
229 that it is easier to maintain.
231 - Improved the type of some variables (particularly blocksize vars) for
232 consistency and proper size.
234 - Got rid of the uint64 type (which we didn't need).
236 - Use a slightly more compatible set of core #include directives.
238 - Defined int32 in a way that ensures that the build dies if we can't
239 find a variable with at least 32 bits.
241 - The daemon's "read only" config item now sets an internal read_only
242 variable that makes extra sure that no write/delete calls on the
243 read-only side can succeed.
245 PROTOCOL DIFFERENCES FOR VERSION 29:
247 - A 16-bit flag-word is transmitted after every file-list index. This
248 indicates what is changing between the sender and the receiver. The
249 generator now transmits an index and a flag-word to indicate when
250 dirs and symlinks have changed (resorting to the old-style outputting
251 of local change-messages for older protocols).
253 - If --inplace is specified, the generator sends an extra byte after
254 the flag-word indicating what kind of basis file is being used for
255 the transfer (see the FNAMECMP_* defines). This information is used
256 to optimize the transfer when the basis file is not the destination.
258 - The sending of exclude names is done using filter-rule syntax. This
259 means that all names have a prefixed rule indicator, even excludes
260 (which used to be sent as a bare pattern, when possible). The -C
261 option will include the per-dir .cvsignore merge file in the list of
262 filter rules so it is positioned correctly (unlike in some older
265 - Rsync sorts the filename list in a different way: it sorts the subdir
266 names after the non-subdir names for each dir's contents, and it
267 always puts a dir's contents immediately after the dir's name in the
268 list. (Previously an item named "foo.txt" would sort in between
269 directory "foo/" and "foo/bar".)
271 - When talking to a protocol 29 rsync daemon, a list-only request
272 is able to note this before the options are sent over the wire, and
273 the new --list-only option is encluded in the options sent over the
276 - When the --stats bytes are sent over the wire (or stored in a batch),
277 they now include two elapsed-time values: one for how long it took to
278 build the file-list, and one for how long it took to send it over the
279 wire (each expressed in thousandths of a second).
281 - When --delete-excluded is specified with some filter rules (AKA
282 excludes), a client sender will now initiate a send of the filter
283 rules to the receiver (older protocols used to omit the sending of
284 excludes in this situation since there were no receiver-specific
285 rules that survived --delete-excluded back then). Note that, as with
286 all the filter-list sending, only items that are significant to the
287 other side will actually be sent over the wire, so the filter-rule
288 list is often empty in this scenario.
290 - A protocol-29 batch file includes a bit for the setting of the --dirs
291 option. Also, the shell script created by --write-batch will use the
292 --filter option instead of --exclude-from to capture any filter rules.
296 - Handle an operating system that use mkdev() in place of makedev().
298 - Improved configure to better handle cross-compiling.
