1 NEWS for rsync 2.6.1 (UNRELEASED)
2 Protocol: 27 (unchanged)
7 * Lower memory use and more optimal transfer of data over
8 the socket (see the INTERNAL section for details).
10 * The RSYNC_PROXY environment variable can now contain a
11 "USER:PASS@" prefix before the "HOST:PORT" information.
14 * The --progress output now mentions how far along in the
15 transfer we are, including both a count of files transferred
16 and a percentage of the total file-count that we're processed.
18 * The configure script now accepts --with-rsyncd-conf=PATH
19 to override the default value of the /etc/rsyncd.conf file.
23 * When -x (--one-file-system) is combined with -L (--copy-links)
24 or --copy-unsafe-links, no symlinked files are skipped, even
25 if the referant file is on a different filesystem.
27 * The --link-dest code now works properly for a non-root user
28 when the UIDs of the source and destination differ and -o was
29 specified, and when the group of the source can't be used on
30 the destination and -g was specified. (Wayne Davison)
32 * Fixed a bug in the handling of -H (hard-links) that might
33 cause the expanded PATH/NAME value of the current item to
34 get overwritten (due to an expanded-name caching bug).
37 * We now reset the "new data has been sent" flag at the start
38 of each file we send. This makes sure that an interrupted
39 transfer with the --partial option set doesn't keep a shorter
40 temp file than the current basis file when no new data has been
41 transfered over the wire for that file. (Wayne Davison)
43 * Fixed a byte-order problem in --batch-mode on big-endian
44 machines. (Jay Fenlason)
46 * Fixed configure bug when running "./configure --disable-ipv6".
49 * Fixed "make test" bug when build dir is not the source dir.
51 * When using --cvs-exclude, the exclude items we get from a
52 directory's .cvsignore file once again only affect that one
53 directory (and not all following directories too).
55 * When transferring a file that has group 0 with -g specified
56 (typically via -a) and not enough privs to retain the group,
57 rsync no longer complains about "chown" failing.
59 * When specifying the USER@HOST: prefix for a file, the USER
60 part can now contain an '@', if needed (i.e. the last '@'
61 is used to find the HOST, not the first).
63 * Fixed some bugs in the handling of group IDs for non-root
64 users: (1) It properly handles a group that the sender didn't
65 have a name for (it would previously skip changing the group
66 on any files in that group). (2) If --numeric-ids is used,
67 rsync no longer attempts to set groups that the user doesn't
68 have the permission to set.
70 * Fixed the "refuse options" setting in the rsyncd.conf file.
72 * Rsync no longer discards a double-slash at the start of a filename
73 when trying to open the file. It also no longer constructs names
74 that start with a double slash (unless the user supplied both).
78 * Most of the I/O is now buffered, which results in a pretty
79 large speedup when running under MS Windows. (Craig Barratt)
81 * Optimizations to the name-handling/comparing code have made
82 some significant reductions in user-CPU time for large file
85 * Some variable-type cleanup that makes the code more consistent.
88 * Reduced memory requirements of hard link preservation.
91 * Implemented a new algorithm for hard-link handling that speeds
92 up the code significantly. (J.W. Schultz and Wayne Davison)
94 * The --hard-link option now uses the first existing file in the
95 group of linked files as the basis for the transfer. This
96 prevents the sub-optimal transfer of a file's data when a new
97 hardlink is added on the sending side and it sorts alphabetically
98 earlier in the list than the files that are already present on the
101 * Dropped support for protocol versions less than 20
102 (2.3.0 released 15 Mar 1999) and activated warnings for
103 protocols less than 25 (2.5.0 released 23 Aug 2001)
104 (Wayne Davison and J.W. Schultz, severally)
106 * More optimal data transmission for --hard-links (protocol 28).
108 * More optimal data transmission for --checksum (protocol 28).
110 * Less memory is used when --checksum is specified.
112 * Less memory is used in the file list (a per-file savings).
114 * Changed hardlink info and file_struct + strings to use
115 allocation pools. This reduces memory use for large
116 filesets and permits freeing memory to the OS. (J.W. Schultz)
118 * The 2 pipes used between the receiver and generator processes
119 (which are forked on the same machine) were reduced to 1 pipe
120 and the protocol improved so that (1) it is now impossible to
121 have the "redo" pipe fill up and hang rsync, and (2) trailing
122 messages from the receiver don't get lost on their way through
123 the generator over to the sender (the latter mainly affected
124 hard-link messages). (Wayne Davison)
126 * The reading & writing of the file list in batch-mode is now
127 handled by the same code that sends & receives the list over
128 the wire. This makes it much easier to maintain.
130 * Optimized the -x (--one-file-system) flag's handling of any
131 mount-point directories we encounter (it no longer scans the
132 contents of the mount-point dirs, just to throw away the data).
134 * Improved the internal uid/gid code to be more portable and
135 a little more optimized.
138 NEWS for rsync 2.6.0 (1 Jan 2004)
139 Protocol: 27 (changed)
144 * "ssh" is now the default remote shell for rsync. If you want to
145 change this, configure like this: "./configure --with-rsh=rsh".
147 * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
148 Note that --from0 affects the line-ending character for all the
149 files read by the --*-from options. (Wayne Davison)
151 * Length of csum2 is now per-file starting with protocol version
154 * Per-file dynamic block size is now sqrt(file length). The
155 per-file checksum size is determined according to an algorithm
156 provided by Donovan Baarda which reduces the probability of rsync
157 algorithm corrupting data and falling back using the whole md4
158 checksums. (J.W. Schultz, Donovan Baarda)
160 * The --stats option no longer includes the (debug) malloc summary
161 unless the verbose option was specified at least twice.
163 * Added a new error/warning code for when files vanish from the
164 sending side. Made vanished source files not interfere with the
165 file-deletion pass when --delete-after was specified.
167 * Various trailing-info sections are now preceded by a newline.
171 * Fixed several exclude/include matching bugs when using wild-cards.
172 This has a several user-visible effects, all of which make the
173 matching more consistent and intuitive. This should hopefully not
174 cause anyone problems since it makes the matching work more like
175 what people are expecting. (Wayne Davison)
177 - A pattern with a "**" no longer causes a "*" to match slashes.
178 For example, with "/*/foo/**", "foo" must be 2 levels deep.
179 [If your string has BOTH "*" and "**" wildcards, changing the
180 "*" wildcards to "**" will provide the old behavior in all
183 - "**/foo" now matches at the base of the transfer (like /foo
184 does). [Use "/**/foo" to get the old behavior in all versions.]
186 - A non-anchored wildcard term floats to match beyond the base of
187 the transfer. E.g. "CVS/R*" matches at the end of the path,
188 just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
189 to get the old behavior in all versions.]
191 - Including a "**" in the match term causes it to be matched
192 against the entire path, not just the name portion, even if
193 there aren't any interior slashes in the term. E.g. "foo**bar"
194 would exclude "/path/foo-bar" (just like before) as well as
195 "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
196 old behavior in all versions.]
198 * The exclude list specified in the daemon's config file is now
199 properly applied to the pulled items no matter how deep the
200 user's file-args are in the source tree. (Wayne Davison)
202 * For protocol version >= 27, mdfour_tail() is called when the
203 block size (including checksum_seed) is a multiple of 64.
204 Previously it was not called, giving the wrong MD4 checksum.
207 * For protocol version >= 27, a 64 bit bit counter is used in
208 mdfour.c as required by the RFC. Previously only a 32 bit bit
209 counter was used, causing incorrect MD4 file checksums for
210 file sizes >= 512MB - 4. (Craig Barratt)
212 * Fixed a crash bug when interacting with older rsync versions and
213 multiple files of the same name are destined for the same dir.
216 * Keep tmp names from overflowing MAXPATHLEN.
218 * Make --link-dest honor the absence of -p, -o, and -g.
220 * Made rsync treat a trailing slash in the destination in a more
223 * Fixed file I/O error detection. (John Van Essen)
225 * Fixed bogus "malformed address {hostname}" message in rsyncd log
226 when checking IP address against hostnames from "hosts allow"
227 and "hosts deny" parameters in config file.
229 * Print heap statistics when verbose >= 2 instead of when >= 1.
231 * Fixed a compression (-z) bug when syncing a mostly-matching file
232 that contains already-compressed data. (Yasuoka Masahiko and
235 * Fixed a bug in the --backup code that could cause deleted files
236 to not get backed up.
238 * When the backup code makes new directories, create them with mode
239 0700 instead of 0755 (since the directory permissions in the
240 backup tree are not yet copied from the main tree).
242 * Call setgroups() in a more portable manner.
244 * Improved file-related error messages to better indicate exactly
245 what pathname failed. (Wayne Davison)
247 * Fixed some bugs in the handling of --delete and --exclude when
248 using the --relative (-R) option. (Wayne Davison)
250 * Fixed bug that prevented regular files from replacing
251 special files and caused a directory in --link-dest or
252 --compare-dest to block the creation of a file with the
253 same path. A directory still cannot be replaced by a
254 regular file unless --delete specified. (J.W. Schultz)
256 * Detect and report when open or opendir succeed but read and
257 readdir fail caused by network filesystem issues and truncated
258 files. (David Norwood, Michael Brown, J.W. Schultz)
260 * Added a fix that should give ssh time to restore the tty settings
261 if the user presses Ctrl-C at an ssh password prompt.
265 * Eliminated vestigial support for old versions that we stopped
266 supporting. (J.W. Schultz)
268 * Simplified some of the option-parsing code. (Wayne Davison)
270 * Some cleanup made to the exclude code, as well as some new
271 defines added to enhance readability. (Wayne Davison)
273 * Changed the protocol-version code so that it can interact at a
274 lower protocol level than the maximum supported by both sides.
275 Added an undocumented option, --protocol=N, to force the value
276 we advertise to the other side (primarily for testing purposes).
