1 | NEWS for rsync 2.6.1 (UNRELEASED) |
2 | Protocol: 27 (unchanged) | |
3 | Changes since 2.6.0: | |
4 | ||
5 | ENHANCEMENTS: | |
6 | ||
0a007489 WD |
7 | * Lower memory use and more optimal transfer of data over |
8 | the socket (see the INTERNAL section for details). | |
9 | ||
823edc68 WD |
10 | * The RSYNC_PROXY environment variable can now contain a |
11 | "USER:PASS@" prefix before the "HOST:PORT" information. | |
12 | (Bardur Arantsson) | |
13 | ||
b0a93231 WD |
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. | |
17 | ||
823edc68 WD |
18 | BUG FIXES: |
19 | ||
20 | * The --link-dest code now works properly for a non-root user | |
5d196694 | 21 | when the UIDs of the source and destination differ and -o was |
823edc68 WD |
22 | specified, and when the group of the source can't be used on |
23 | the destination and -g was specified. (Wayne Davison) | |
24 | ||
a18381ac WD |
25 | * Fixed a bug in the handling of -H (hard-links) that might |
26 | cause the expanded PATH/NAME value of the current item to | |
27 | get overwritten (due to an expanded-name caching bug). | |
28 | (Wayne Davison) | |
823edc68 | 29 | |
73a4bdfd WD |
30 | * We now reset the "new data has been sent" flag at the start |
31 | of each file we send. This makes sure that an interrupted | |
32 | transfer with the --partial option set doesn't keep a shorter | |
33 | temp file than the current basis file when no new data has been | |
34 | transfered over the wire for that file. (Wayne Davison) | |
823edc68 | 35 | |
e7bef922 WD |
36 | * Fixed a byte-order problem in --batch-mode on big-endian |
37 | machines. (Jay Fenlason) | |
38 | ||
0a007489 WD |
39 | * Fixed configure bug when running "./configure --disable-ipv6". |
40 | (Wayne Davison) | |
41 | ||
42 | * Fixed "make test" bug when build dir is not the source dir. | |
43 | ||
66964002 WD |
44 | * When using --cvs-exclude, the exclude items we get from a |
45 | directory's .cvsignore file once again only affect that one | |
46 | directory (and not all following directories too). | |
47 | ||
b0a93231 WD |
48 | * When transferring a file that has group 0 with -g specified |
49 | (typically via -a) and not enough privs to retain the group, | |
50 | rsync no longer complains about chown failing. | |
51 | ||
0c819b76 WD |
52 | * When specifying the USER@HOST: prefix for a file, the USER |
53 | part can now contain an '@', if needed (i.e. the last '@' | |
54 | is used to find the HOST, not the first). | |
55 | ||
823edc68 WD |
56 | INTERNAL: |
57 | ||
86c4601e | 58 | * Most of the I/O is now buffered, which results in a pretty |
a18381ac | 59 | large speedup when running under MS Windows. (Craig Barratt) |
823edc68 WD |
60 | |
61 | * Optimizations to the name-handling/comparing code have made | |
0a007489 | 62 | some significant reductions in user-CPU time for large file |
823edc68 WD |
63 | sets. (Wayne Davison) |
64 | ||
31e7451a WD |
65 | * Some variable-type cleanup that makes the code more consistent. |
66 | (Wayne Davison) | |
67 | ||
279b1c1e | 68 | * Reduced memory requirements of hard link preservation. |
0a007489 | 69 | (J.W. Schultz) |
279b1c1e | 70 | |
f8ebdf92 WD |
71 | * Implemented a new algorithm for hard-link handling that speeds |
72 | up the code significantly. (J.W. Schultz and Wayne Davison) | |
73 | ||
64f21c31 WD |
74 | * The --hard-link option now uses the first existing file in the |
75 | group of linked files as the basis for the transfer. This | |
76 | prevents the sub-optimal transfer of a file's data when a new | |
77 | hardlink is added on the sending side and it sorts alphabetically | |
78 | earlier in the list than the files that are already present on the | |
79 | receiving side. | |
80 | ||
1a62c49d | 81 | * Got rid of support for protocol versions 17 and 18 (which are |
0a007489 | 82 | both over 6 years old). (Wayne Davison) |
aa953c32 | 83 | |
1a62c49d WD |
84 | * More optimal data transmission for --hard-links (protocol 28). |
85 | ||
86 | * More optimal data transmission for --checksum (protocol 28). | |
87 | ||
64f21c31 | 88 | * Less memory is used when --checksum is specified. |
1a62c49d | 89 | |
64f21c31 | 90 | * Less memory is used in the file list (a per-file savings). |
0a007489 | 91 | |
442743b8 | 92 | * The 2 pipes used between the receiver and generator processes |
b0a93231 WD |
93 | (which are forked on the same machine) were reduced to 1 pipe |
94 | and the protocol improved so that (1) it is now impossible to | |
95 | have the "redo" pipe fill up and hang rsync, and (2) trailing | |
96 | messages from the receiver don't get lost on their way through | |
97 | the generator over to the sender (the latter mainly affected | |
98 | hard-link messages). (Wayne Davison) | |
99 | ||
100 | * The reading & writing of the file list in batch-mode is now | |
101 | handled by the same code that sends & receives the list over | |
102 | the wire. This makes it much easier to maintain. | |
442743b8 | 103 | |
73a4bdfd WD |
104 | * Optimized the -x (--one-file-system) flag's handling of any |
105 | mount-point directories we encounter (it no longer scans the | |
106 | contents of the mount-point dirs, just to throw away the data). | |

276877cf | 109 | NEWS for rsync 2.6.0 (1 Jan 2004) |
195bd906 | 110 | Protocol: 27 (changed) |
276877cf | 111 | Changes since 2.5.7: |
89855e78 WD |
112 | |
113 | ENHANCEMENTS: | |
114 | ||
e636af6b WD |
115 | * "ssh" is now the default remote shell for rsync. If you want to |
116 | change this, configure like this: "./configure --with-rsh=rsh". | |
117 | ||
58665d23 | 118 | * Added --files-from, --no-relative, --no-implied-dirs, and --from0. |
89855e78 | 119 | Note that --from0 affects the line-ending character for all the |
d00daf1f | 120 | files read by the --*-from options. (Wayne Davison) |
89855e78 | 121 | |
9e83fa99 | 122 | * Length of csum2 is now per-file starting with protocol version |
58665d23 | 123 | 27. (J.W. Schultz) |
195bd906 | 124 | |
9e83fa99 WD |
125 | * Per-file dynamic block size is now sqrt(file length). The |
126 | per-file checksum size is determined according to an algorithm | |
127 | provided by Donovan Baarda which reduces the probability of rsync | |
128 | algorithm corrupting data and falling back using the whole md4 | |
58665d23 | 129 | checksums. (J.W. Schultz, Donovan Baarda) |
195bd906 | 130 | |
727fa368 WD |
131 | * The --stats option no longer includes the (debug) malloc summary |
132 | unless the verbose option was specified at least twice. | |
133 | ||
d00daf1f WD |
134 | * Added a new error/warning code for when files vanish from the |
135 | sending side. Made vanished source files not interfere with the | |
136 | file-deletion pass when --delete-after was specified. | |
137 | ||
9e83fa99 WD |
138 | * Various trailing-info sections are now preceded by a newline. |
139 | ||
89855e78 WD |
140 | BUG FIXES: |
141 | ||
f2fe4903 WD |
142 | * Fixed several exclude/include matching bugs when using wild-cards. |
143 | This has a several user-visible effects, all of which make the | |
144 | matching more consistent and intuitive. This should hopefully not | |
145 | cause anyone problems since it makes the matching work more like | |
146 | what people are expecting. (Wayne Davison) | |
147 | ||
592f4696 WD |
148 | - A pattern with a "**" no longer causes a "*" to match slashes. |
149 | For example, with "/*/foo/**", "foo" must be 2 levels deep. | |
faf11086 WD |
150 | [If your string has BOTH "*" and "**" wildcards, changing the |
151 | "*" wildcards to "**" will provide the old behavior in all | |
152 | versions.] | |
592f4696 | 153 | |
52fa4d78 WD |
154 | - "**/foo" now matches at the base of the transfer (like /foo |
155 | does). [Use "/**/foo" to get the old behavior in all versions.] | |
f2fe4903 | 156 | |
52fa4d78 | 157 | - A non-anchored wildcard term floats to match beyond the base of |
f2fe4903 | 158 | the transfer. E.g. "CVS/R*" matches at the end of the path, |
52fa4d78 WD |
159 | just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*" |
160 | to get the old behavior in all versions.] | |
f2fe4903 WD |
161 | |
162 | - Including a "**" in the match term causes it to be matched | |
163 | against the entire path, not just the name portion, even if | |
164 | there aren't any interior slashes in the term. E.g. "foo**bar" | |
165 | would exclude "/path/foo-bar" (just like before) as well as | |
52fa4d78 WD |
166 | "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the |
167 | old behavior in all versions.] | |
f2fe4903 | 168 | |
52e628a8 WD |
169 | * The exclude list specified in the daemon's config file is now |
170 | properly applied to the pulled items no matter how deep the | |
d00daf1f | 171 | user's file-args are in the source tree. (Wayne Davison) |
52e628a8 | 172 | |
da2bcdd1 | 173 | * For protocol version >= 27, mdfour_tail() is called when the |
58665d23 WD |
174 | block size (including checksum_seed) is a multiple of 64. |
175 | Previously it was not called, giving the wrong MD4 checksum. | |
176 | (Craig Barratt) | |
256a9e37 | 177 | |
da2bcdd1 | 178 | * For protocol version >= 27, a 64 bit bit counter is used in |
58665d23 WD |
179 | mdfour.c as required by the RFC. Previously only a 32 bit bit |
180 | counter was used, causing incorrect MD4 file checksums for | |
181 | file sizes >= 512MB - 4. (Craig Barratt) | |
195bd906 | 182 | |
da2bcdd1 | 183 | * Fixed a crash bug when interacting with older rsync versions and |
89855e78 WD |
184 | multiple files of the same name are destined for the same dir. |
185 | (Wayne Davison) | |
186 | ||
58665d23 | 187 | * Keep tmp names from overflowing MAXPATHLEN. |
89855e78 | 188 | |
da2bcdd1 | 189 | * Make --link-dest honor the absence of -p, -o, and -g. |
fab1f889 | 190 | |
8113a033 WD |
191 | * Made rsync treat a trailing slash in the destination in a more |
192 | consistent manner. | |
193 | ||
9b746433 | 194 | * Fixed file I/O error detection. (John Van Essen) |
fab1f889 | 195 | |
256a9e37 WD |
196 | * Fixed bogus "malformed address {hostname}" message in rsyncd log |
197 | when checking IP address against hostnames from "hosts allow" | |
198 | and "hosts deny" parameters in config file. | |
199 | ||
200 | * Print heap statistics when verbose >= 2 instead of when >= 1. | |
201 | ||
90045413 WD |
202 | * Fixed a compression (-z) bug when syncing a mostly-matching file |
203 | that contains already-compressed data. (Yasuoka Masahiko and | |
204 | Wayne Davison) | |
205 | ||
d594399c WD |
206 | * Fixed a bug in the --backup code that could cause deleted files |
207 | to not get backed up. | |
208 | ||
860bdd45 WD |
209 | * When the backup code makes new directories, create them with mode |
210 | 0700 instead of 0755 (since the directory permissions in the | |
211 | backup tree are not yet copied from the main tree). | |
212 | ||
2c873122 WD |
213 | * Call setgroups() in a more portable manner. |
214 | ||
aa6dc37c WD |
215 | * Improved file-related error messages to better indicate exactly |
216 | what pathname failed. (Wayne Davison) | |
2c873122 WD |
217 | |
218 | * Fixed some bugs in the handling of --delete and --exclude when | |
219 | using the --relative (-R) option. (Wayne Davison) | |
4a7ee79d | 220 | |
d89a3a31 S |
221 | * Fixed bug that prevented regular files from replacing |
222 | special files and caused a directory in --link-dest or | |
223 | --compare-dest to block the creation of a file with the | |
224 | same path. A directory still cannot be replaced by a | |
225 | regular file unless --delete specified. (J.W. Schultz) | |
226 | ||
6a7cc46c | 227 | * Detect and report when open or opendir succeed but read and |
52fa4d78 | 228 | readdir fail caused by network filesystem issues and truncated |
6a7cc46c S |
229 | files. (David Norwood, Michael Brown, J.W. Schultz) |
230 | ||
65653a65 WD |
231 | * Added a fix that should give ssh time to restore the tty settings |
232 | if the user presses Ctrl-C at an ssh password prompt. | |
233 | ||
89855e78 WD |
234 | INTERNAL: |
235 | ||
58665d23 | 236 | * Eliminated vestigial support for old versions that we stopped |
89855e78 WD |
237 | supporting. (J.W. Schultz) |
238 | ||
58665d23 | 239 | * Simplified some of the option-parsing code. (Wayne Davison) |
89855e78 | 240 | |
52e628a8 WD |
241 | * Some cleanup made to the exclude code, as well as some new |
242 | defines added to enhance readability. (Wayne Davison) | |
243 | ||
aa6dc37c WD |
244 | * Changed the protocol-version code so that it can interact at a |
245 | lower protocol level than the maximum supported by both sides. | |
246 | Added an undocumented option, --protocol=N, to force the value | |
247 | we advertise to the other side (primarily for testing purposes). | |
248 | (Wayne Davison) |
