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 | ||
14 | BUG FIXES: | |
15 | ||
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) | |
20 | ||
a18381ac WD |
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). | |
24 | (Wayne Davison) | |
823edc68 WD |
25 | |
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 | |
0a007489 | 29 | the wire. (Wayne Davison) |
823edc68 | 30 | |
e7bef922 WD |
31 | * Fixed a byte-order problem in --batch-mode on big-endian |
32 | machines. (Jay Fenlason) | |
33 | ||
0a007489 WD |
34 | * Fixed configure bug when running "./configure --disable-ipv6". |
35 | (Wayne Davison) | |
36 | ||
37 | * Fixed "make test" bug when build dir is not the source dir. | |
38 | ||
66964002 WD |
39 | * When using --cvs-exclude, the exclude items we get from a |
40 | directory's .cvsignore file once again only affect that one | |
41 | directory (and not all following directories too). | |
42 | ||
0c819b76 WD |
43 | * When specifying the USER@HOST: prefix for a file, the USER |
44 | part can now contain an '@', if needed (i.e. the last '@' | |
45 | is used to find the HOST, not the first). | |
46 | ||
823edc68 WD |
47 | INTERNAL: |
48 | ||
86c4601e | 49 | * Most of the I/O is now buffered, which results in a pretty |
a18381ac | 50 | large speedup when running under MS Windows. (Craig Barratt) |
823edc68 WD |
51 | |
52 | * Optimizations to the name-handling/comparing code have made | |
0a007489 | 53 | some significant reductions in user-CPU time for large file |
823edc68 WD |
54 | sets. (Wayne Davison) |
55 | ||
31e7451a WD |
56 | * Some variable-type cleanup that makes the code more consistent. |
57 | (Wayne Davison) | |
58 | ||
279b1c1e | 59 | * Reduced memory requirements of hard link preservation. |
0a007489 | 60 | (J.W. Schultz) |
279b1c1e | 61 | |
f8ebdf92 WD |
62 | * Implemented a new algorithm for hard-link handling that speeds |
63 | up the code significantly. (J.W. Schultz and Wayne Davison) | |
64 | ||
1a62c49d | 65 | * Got rid of support for protocol versions 17 and 18 (which are |
0a007489 | 66 | both over 6 years old). (Wayne Davison) |
aa953c32 | 67 | |
1a62c49d WD |
68 | * More optimal data transmission for --hard-links (protocol 28). |
69 | ||
70 | * More optimal data transmission for --checksum (protocol 28). | |
71 | ||
72 | * Less memory used for holding --checksum data. | |
73 | ||
0a007489 WD |
74 | * Less memory used per-file in the file list. |
75 | ||
442743b8 WD |
76 | * The 2 pipes used between the receiver and generator processes |
77 | (which are forked on the same machine) were reduced to 1 pipe and | |
78 | the protocol improved so that (1) it is now impossible to have the | |
79 | "redo" pipe fill up and hang rsync, and (2) trailing messages from | |
80 | the receiver don't get lost on their way to through generator over | |
81 | to the sender. (Wayne Davison) | |

276877cf | 84 | NEWS for rsync 2.6.0 (1 Jan 2004) |
195bd906 | 85 | Protocol: 27 (changed) |
276877cf | 86 | Changes since 2.5.7: |
89855e78 WD |
87 | |
88 | ENHANCEMENTS: | |
89 | ||
e636af6b WD |
90 | * "ssh" is now the default remote shell for rsync. If you want to |
91 | change this, configure like this: "./configure --with-rsh=rsh". | |
92 | ||
58665d23 | 93 | * Added --files-from, --no-relative, --no-implied-dirs, and --from0. |
89855e78 | 94 | Note that --from0 affects the line-ending character for all the |
d00daf1f | 95 | files read by the --*-from options. (Wayne Davison) |
89855e78 | 96 | |
9e83fa99 | 97 | * Length of csum2 is now per-file starting with protocol version |
58665d23 | 98 | 27. (J.W. Schultz) |
195bd906 | 99 | |
9e83fa99 WD |
100 | * Per-file dynamic block size is now sqrt(file length). The |
101 | per-file checksum size is determined according to an algorithm | |
102 | provided by Donovan Baarda which reduces the probability of rsync | |
103 | algorithm corrupting data and falling back using the whole md4 | |
58665d23 | 104 | checksums. (J.W. Schultz, Donovan Baarda) |
195bd906 | 105 | |
727fa368 WD |
106 | * The --stats option no longer includes the (debug) malloc summary |
107 | unless the verbose option was specified at least twice. | |
108 | ||
d00daf1f WD |
109 | * Added a new error/warning code for when files vanish from the |
110 | sending side. Made vanished source files not interfere with the | |
111 | file-deletion pass when --delete-after was specified. | |
112 | ||
9e83fa99 WD |
113 | * Various trailing-info sections are now preceded by a newline. |
114 | ||
89855e78 WD |
115 | BUG FIXES: |
116 | ||
f2fe4903 WD |
117 | * Fixed several exclude/include matching bugs when using wild-cards. |
118 | This has a several user-visible effects, all of which make the | |
119 | matching more consistent and intuitive. This should hopefully not | |
120 | cause anyone problems since it makes the matching work more like | |
121 | what people are expecting. (Wayne Davison) | |
122 | ||
592f4696 WD |
123 | - A pattern with a "**" no longer causes a "*" to match slashes. |
124 | For example, with "/*/foo/**", "foo" must be 2 levels deep. | |
faf11086 WD |
125 | [If your string has BOTH "*" and "**" wildcards, changing the |
126 | "*" wildcards to "**" will provide the old behavior in all | |
127 | versions.] | |
592f4696 | 128 | |
52fa4d78 WD |
129 | - "**/foo" now matches at the base of the transfer (like /foo |
130 | does). [Use "/**/foo" to get the old behavior in all versions.] | |
f2fe4903 | 131 | |
52fa4d78 | 132 | - A non-anchored wildcard term floats to match beyond the base of |
f2fe4903 | 133 | the transfer. E.g. "CVS/R*" matches at the end of the path, |
52fa4d78 WD |
134 | just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*" |
135 | to get the old behavior in all versions.] | |
f2fe4903 WD |
136 | |
137 | - Including a "**" in the match term causes it to be matched | |
138 | against the entire path, not just the name portion, even if | |
139 | there aren't any interior slashes in the term. E.g. "foo**bar" | |
140 | would exclude "/path/foo-bar" (just like before) as well as | |
52fa4d78 WD |
141 | "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the |
142 | old behavior in all versions.] | |
f2fe4903 | 143 | |
52e628a8 WD |
144 | * The exclude list specified in the daemon's config file is now |
145 | properly applied to the pulled items no matter how deep the | |
d00daf1f | 146 | user's file-args are in the source tree. (Wayne Davison) |
52e628a8 | 147 | |
da2bcdd1 | 148 | * For protocol version >= 27, mdfour_tail() is called when the |
58665d23 WD |
149 | block size (including checksum_seed) is a multiple of 64. |
150 | Previously it was not called, giving the wrong MD4 checksum. | |
151 | (Craig Barratt) | |
256a9e37 | 152 | |
da2bcdd1 | 153 | * For protocol version >= 27, a 64 bit bit counter is used in |
58665d23 WD |
154 | mdfour.c as required by the RFC. Previously only a 32 bit bit |
155 | counter was used, causing incorrect MD4 file checksums for | |
156 | file sizes >= 512MB - 4. (Craig Barratt) | |
195bd906 | 157 | |
da2bcdd1 | 158 | * Fixed a crash bug when interacting with older rsync versions and |
89855e78 WD |
159 | multiple files of the same name are destined for the same dir. |
160 | (Wayne Davison) | |
161 | ||
58665d23 | 162 | * Keep tmp names from overflowing MAXPATHLEN. |
89855e78 | 163 | |
da2bcdd1 | 164 | * Make --link-dest honor the absence of -p, -o, and -g. |
fab1f889 | 165 | |
8113a033 WD |
166 | * Made rsync treat a trailing slash in the destination in a more |
167 | consistent manner. | |
168 | ||
9b746433 | 169 | * Fixed file I/O error detection. (John Van Essen) |
fab1f889 | 170 | |
256a9e37 WD |
171 | * Fixed bogus "malformed address {hostname}" message in rsyncd log |
172 | when checking IP address against hostnames from "hosts allow" | |
173 | and "hosts deny" parameters in config file. | |
174 | ||
175 | * Print heap statistics when verbose >= 2 instead of when >= 1. | |
176 | ||
90045413 WD |
177 | * Fixed a compression (-z) bug when syncing a mostly-matching file |
178 | that contains already-compressed data. (Yasuoka Masahiko and | |
179 | Wayne Davison) | |
180 | ||
d594399c WD |
181 | * Fixed a bug in the --backup code that could cause deleted files |
182 | to not get backed up. | |
183 | ||
860bdd45 WD |
184 | * When the backup code makes new directories, create them with mode |
185 | 0700 instead of 0755 (since the directory permissions in the | |
186 | backup tree are not yet copied from the main tree). | |
187 | ||
2c873122 WD |
188 | * Call setgroups() in a more portable manner. |
189 | ||
aa6dc37c WD |
190 | * Improved file-related error messages to better indicate exactly |
191 | what pathname failed. (Wayne Davison) | |
2c873122 WD |
192 | |
193 | * Fixed some bugs in the handling of --delete and --exclude when | |
194 | using the --relative (-R) option. (Wayne Davison) | |
4a7ee79d | 195 | |
d89a3a31 S |
196 | * Fixed bug that prevented regular files from replacing |
197 | special files and caused a directory in --link-dest or | |
198 | --compare-dest to block the creation of a file with the | |
199 | same path. A directory still cannot be replaced by a | |
200 | regular file unless --delete specified. (J.W. Schultz) | |
201 | ||
6a7cc46c | 202 | * Detect and report when open or opendir succeed but read and |
52fa4d78 | 203 | readdir fail caused by network filesystem issues and truncated |
6a7cc46c S |
204 | files. (David Norwood, Michael Brown, J.W. Schultz) |
205 | ||
65653a65 WD |
206 | * Added a fix that should give ssh time to restore the tty settings |
207 | if the user presses Ctrl-C at an ssh password prompt. | |
208 | ||
89855e78 WD |
209 | INTERNAL: |
210 | ||
58665d23 | 211 | * Eliminated vestigial support for old versions that we stopped |
89855e78 WD |
212 | supporting. (J.W. Schultz) |
213 | ||
58665d23 | 214 | * Simplified some of the option-parsing code. (Wayne Davison) |
89855e78 | 215 | |
52e628a8 WD |
216 | * Some cleanup made to the exclude code, as well as some new |
217 | defines added to enhance readability. (Wayne Davison) | |
218 | ||
aa6dc37c WD |
219 | * Changed the protocol-version code so that it can interact at a |
220 | lower protocol level than the maximum supported by both sides. | |
221 | Added an undocumented option, --protocol=N, to force the value | |
222 | we advertise to the other side (primarily for testing purposes). | |
223 | (Wayne Davison) |
