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.
16 * The --link-dest code now works properly for a non-root user
17 when the UIDs of the source and destination differ and -u was
18 specified, and when the group of the source can't be used on
19 the destination and -g was specified. (Wayne Davison)
21 * Fixed a bug in the handling of -H (hard-links) that might
22 cause the expanded PATH/NAME value of the current item to
23 get overwritten (due to an expanded-name caching bug).
26 * Keep per-file track of the sending of literal data with
27 --partial so that an interrupted transfer doesn't keep a
28 shorter temp file when no new data has been transfered over
29 the wire. (Wayne Davison)
31 * Fixed a byte-order problem in --batch-mode on big-endian
32 machines. (Jay Fenlason)
34 * Fixed configure bug when running "./configure --disable-ipv6".
37 * Fixed "make test" bug when build dir is not the source dir.
41 * Most of the I/O is now buffered, which results in a pretty
42 large speedup when running under MS Windows. (Craig Barratt)
44 * Optimizations to the name-handling/comparing code have made
45 some significant reductions in user-CPU time for large file
48 * Some variable-type cleanup that makes the code more consistent.
51 * Reduced memory requirements of hard link preservation.
54 * Implemented a new algorithm for hard-link handling that speeds
55 up the code significantly. (J.W. Schultz and Wayne Davison)
57 * Got rid of support for protocol versions 17 and 18 (which are
58 both over 6 years old). (Wayne Davison)
60 * More optimal data transmission for --hard-links (protocol 28).
62 * More optimal data transmission for --checksum (protocol 28).
64 * Less memory used for holding --checksum data.
66 * Less memory used per-file in the file list.
69 NEWS for rsync 2.6.0 (1 Jan 2004)
70 Protocol: 27 (changed)
75 * "ssh" is now the default remote shell for rsync. If you want to
76 change this, configure like this: "./configure --with-rsh=rsh".
78 * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
79 Note that --from0 affects the line-ending character for all the
80 files read by the --*-from options. (Wayne Davison)
82 * Length of csum2 is now per-file starting with protocol version
85 * Per-file dynamic block size is now sqrt(file length). The
86 per-file checksum size is determined according to an algorithm
87 provided by Donovan Baarda which reduces the probability of rsync
88 algorithm corrupting data and falling back using the whole md4
89 checksums. (J.W. Schultz, Donovan Baarda)
91 * The --stats option no longer includes the (debug) malloc summary
92 unless the verbose option was specified at least twice.
94 * Added a new error/warning code for when files vanish from the
95 sending side. Made vanished source files not interfere with the
96 file-deletion pass when --delete-after was specified.
98 * Various trailing-info sections are now preceded by a newline.
102 * Fixed several exclude/include matching bugs when using wild-cards.
103 This has a several user-visible effects, all of which make the
104 matching more consistent and intuitive. This should hopefully not
105 cause anyone problems since it makes the matching work more like
106 what people are expecting. (Wayne Davison)
108 - A pattern with a "**" no longer causes a "*" to match slashes.
109 For example, with "/*/foo/**", "foo" must be 2 levels deep.
110 [If your string has BOTH "*" and "**" wildcards, changing the
111 "*" wildcards to "**" will provide the old behavior in all
114 - "**/foo" now matches at the base of the transfer (like /foo
115 does). [Use "/**/foo" to get the old behavior in all versions.]
117 - A non-anchored wildcard term floats to match beyond the base of
118 the transfer. E.g. "CVS/R*" matches at the end of the path,
119 just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
120 to get the old behavior in all versions.]
122 - Including a "**" in the match term causes it to be matched
123 against the entire path, not just the name portion, even if
124 there aren't any interior slashes in the term. E.g. "foo**bar"
125 would exclude "/path/foo-bar" (just like before) as well as
126 "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
127 old behavior in all versions.]
129 * The exclude list specified in the daemon's config file is now
130 properly applied to the pulled items no matter how deep the
131 user's file-args are in the source tree. (Wayne Davison)
133 * For protocol version >= 27, mdfour_tail() is called when the
134 block size (including checksum_seed) is a multiple of 64.
135 Previously it was not called, giving the wrong MD4 checksum.
138 * For protocol version >= 27, a 64 bit bit counter is used in
139 mdfour.c as required by the RFC. Previously only a 32 bit bit
140 counter was used, causing incorrect MD4 file checksums for
141 file sizes >= 512MB - 4. (Craig Barratt)
143 * Fixed a crash bug when interacting with older rsync versions and
144 multiple files of the same name are destined for the same dir.
147 * Keep tmp names from overflowing MAXPATHLEN.
149 * Make --link-dest honor the absence of -p, -o, and -g.
151 * Made rsync treat a trailing slash in the destination in a more
154 * Fixed file I/O error detection. (John Van Essen)
156 * Fixed bogus "malformed address {hostname}" message in rsyncd log
157 when checking IP address against hostnames from "hosts allow"
158 and "hosts deny" parameters in config file.
160 * Print heap statistics when verbose >= 2 instead of when >= 1.
162 * Fixed a compression (-z) bug when syncing a mostly-matching file
163 that contains already-compressed data. (Yasuoka Masahiko and
166 * Fixed a bug in the --backup code that could cause deleted files
167 to not get backed up.
169 * When the backup code makes new directories, create them with mode
170 0700 instead of 0755 (since the directory permissions in the
171 backup tree are not yet copied from the main tree).
173 * Call setgroups() in a more portable manner.
175 * Improved file-related error messages to better indicate exactly
176 what pathname failed. (Wayne Davison)
178 * Fixed some bugs in the handling of --delete and --exclude when
179 using the --relative (-R) option. (Wayne Davison)
181 * Fixed bug that prevented regular files from replacing
182 special files and caused a directory in --link-dest or
183 --compare-dest to block the creation of a file with the
184 same path. A directory still cannot be replaced by a
185 regular file unless --delete specified. (J.W. Schultz)
187 * Detect and report when open or opendir succeed but read and
188 readdir fail caused by network filesystem issues and truncated
189 files. (David Norwood, Michael Brown, J.W. Schultz)
191 * Added a fix that should give ssh time to restore the tty settings
192 if the user presses Ctrl-C at an ssh password prompt.
196 * Eliminated vestigial support for old versions that we stopped
197 supporting. (J.W. Schultz)
199 * Simplified some of the option-parsing code. (Wayne Davison)
201 * Some cleanup made to the exclude code, as well as some new
202 defines added to enhance readability. (Wayne Davison)
204 * Changed the protocol-version code so that it can interact at a
205 lower protocol level than the maximum supported by both sides.
206 Added an undocumented option, --protocol=N, to force the value
207 we advertise to the other side (primarily for testing purposes).
