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 | ||
823edc68 WD |
39 | INTERNAL: |
40 | ||
86c4601e | 41 | * Most of the I/O is now buffered, which results in a pretty |
a18381ac | 42 | large speedup when running under MS Windows. (Craig Barratt) |
823edc68 WD |
43 | |
44 | * Optimizations to the name-handling/comparing code have made | |
0a007489 | 45 | some significant reductions in user-CPU time for large file |
823edc68 WD |
46 | sets. (Wayne Davison) |
47 | ||
31e7451a WD |
48 | * Some variable-type cleanup that makes the code more consistent. |
49 | (Wayne Davison) | |
50 | ||
279b1c1e | 51 | * Reduced memory requirements of hard link preservation. |
0a007489 | 52 | (J.W. Schultz) |
279b1c1e | 53 | |
f8ebdf92 WD |
54 | * Implemented a new algorithm for hard-link handling that speeds |
55 | up the code significantly. (J.W. Schultz and Wayne Davison) | |
56 | ||
1a62c49d | 57 | * Got rid of support for protocol versions 17 and 18 (which are |
0a007489 | 58 | both over 6 years old). (Wayne Davison) |
aa953c32 | 59 | |
1a62c49d WD |
60 | * More optimal data transmission for --hard-links (protocol 28). |
61 | ||
62 | * More optimal data transmission for --checksum (protocol 28). | |
63 | ||
64 | * Less memory used for holding --checksum data. | |
65 | ||
0a007489 WD |
66 | * Less memory used per-file in the file list. |
67 | ||
442743b8 WD |
68 | * The 2 pipes used between the receiver and generator processes |
69 | (which are forked on the same machine) were reduced to 1 pipe and | |
70 | the protocol improved so that (1) it is now impossible to have the | |
71 | "redo" pipe fill up and hang rsync, and (2) trailing messages from | |
72 | the receiver don't get lost on their way to through generator over | |
73 | to the sender. (Wayne Davison) | |

195bd906 | 77 | Protocol: 27 (changed) |
276877cf | 78 | Changes since 2.5.7: |
89855e78 WD |
79 | |
80 | ENHANCEMENTS: | |
81 | ||
e636af6b WD |
82 | * "ssh" is now the default remote shell for rsync. If you want to |
83 | change this, configure like this: "./configure --with-rsh=rsh". | |
84 | ||
58665d23 | 85 | * Added --files-from, --no-relative, --no-implied-dirs, and --from0. |
89855e78 | 86 | Note that --from0 affects the line-ending character for all the |
d00daf1f | 87 | files read by the --*-from options. (Wayne Davison) |
89855e78 | 88 | |
9e83fa99 | 89 | * Length of csum2 is now per-file starting with protocol version |
58665d23 | 90 | 27. (J.W. Schultz) |
195bd906 | 91 | |
9e83fa99 WD |
92 | * Per-file dynamic block size is now sqrt(file length). The |
93 | per-file checksum size is determined according to an algorithm | |
94 | provided by Donovan Baarda which reduces the probability of rsync | |
95 | algorithm corrupting data and falling back using the whole md4 | |
58665d23 | 96 | checksums. (J.W. Schultz, Donovan Baarda) |
195bd906 | 97 | |
727fa368 WD |
98 | * The --stats option no longer includes the (debug) malloc summary |
99 | unless the verbose option was specified at least twice. | |
100 | ||
d00daf1f WD |
101 | * Added a new error/warning code for when files vanish from the |
102 | sending side. Made vanished source files not interfere with the | |
103 | file-deletion pass when --delete-after was specified. | |
104 | ||
9e83fa99 WD |
105 | * Various trailing-info sections are now preceded by a newline. |
106 | ||
89855e78 WD |
107 | BUG FIXES: |
108 | ||
f2fe4903 WD |
109 | * Fixed several exclude/include matching bugs when using wild-cards. |
110 | This has a several user-visible effects, all of which make the | |
111 | matching more consistent and intuitive. This should hopefully not | |
112 | cause anyone problems since it makes the matching work more like | |
113 | what people are expecting. (Wayne Davison) | |
114 | ||
592f4696 WD |
115 | - A pattern with a "**" no longer causes a "*" to match slashes. |
116 | For example, with "/*/foo/**", "foo" must be 2 levels deep. | |
faf11086 WD |
117 | [If your string has BOTH "*" and "**" wildcards, changing the |
118 | "*" wildcards to "**" will provide the old behavior in all | |
119 | versions.] | |
592f4696 | 120 | |
52fa4d78 WD |
121 | - "**/foo" now matches at the base of the transfer (like /foo |
122 | does). [Use "/**/foo" to get the old behavior in all versions.] | |
f2fe4903 | 123 | |
52fa4d78 | 124 | - A non-anchored wildcard term floats to match beyond the base of |
f2fe4903 | 125 | the transfer. E.g. "CVS/R*" matches at the end of the path, |
52fa4d78 WD |
126 | just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*" |
127 | to get the old behavior in all versions.] | |
f2fe4903 WD |
128 | |
129 | - Including a "**" in the match term causes it to be matched | |
130 | against the entire path, not just the name portion, even if | |
131 | there aren't any interior slashes in the term. E.g. "foo**bar" | |
132 | would exclude "/path/foo-bar" (just like before) as well as | |
52fa4d78 WD |
133 | "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the |
134 | old behavior in all versions.] | |
f2fe4903 | 135 | |
52e628a8 WD |
136 | * The exclude list specified in the daemon's config file is now |
137 | properly applied to the pulled items no matter how deep the | |
d00daf1f | 138 | user's file-args are in the source tree. (Wayne Davison) |
52e628a8 | 139 | |
da2bcdd1 | 140 | * For protocol version >= 27, mdfour_tail() is called when the |
58665d23 WD |
141 | block size (including checksum_seed) is a multiple of 64. |
142 | Previously it was not called, giving the wrong MD4 checksum. | |
143 | (Craig Barratt) | |
256a9e37 | 144 | |
da2bcdd1 | 145 | * For protocol version >= 27, a 64 bit bit counter is used in |
58665d23 WD |
146 | mdfour.c as required by the RFC. Previously only a 32 bit bit |
147 | counter was used, causing incorrect MD4 file checksums for | |
148 | file sizes >= 512MB - 4. (Craig Barratt) | |
195bd906 | 149 | |
da2bcdd1 | 150 | * Fixed a crash bug when interacting with older rsync versions and |
89855e78 WD |
151 | multiple files of the same name are destined for the same dir. |
152 | (Wayne Davison) | |
153 | ||
58665d23 | 154 | * Keep tmp names from overflowing MAXPATHLEN. |
89855e78 | 155 | |
da2bcdd1 | 156 | * Make --link-dest honor the absence of -p, -o, and -g. |
fab1f889 | 157 | |
8113a033 WD |
158 | * Made rsync treat a trailing slash in the destination in a more |
159 | consistent manner. | |
160 | ||
9b746433 | 161 | * Fixed file I/O error detection. (John Van Essen) |
fab1f889 | 162 | |
256a9e37 WD |
163 | * Fixed bogus "malformed address {hostname}" message in rsyncd log |
164 | when checking IP address against hostnames from "hosts allow" | |
165 | and "hosts deny" parameters in config file. | |
166 | ||
167 | * Print heap statistics when verbose >= 2 instead of when >= 1. | |
168 | ||
90045413 WD |
169 | * Fixed a compression (-z) bug when syncing a mostly-matching file |
170 | that contains already-compressed data. (Yasuoka Masahiko and | |
171 | Wayne Davison) | |
172 | ||
d594399c WD |
173 | * Fixed a bug in the --backup code that could cause deleted files |
174 | to not get backed up. | |
175 | ||
860bdd45 WD |
176 | * When the backup code makes new directories, create them with mode |
177 | 0700 instead of 0755 (since the directory permissions in the | |
178 | backup tree are not yet copied from the main tree). | |
179 | ||
2c873122 WD |
180 | * Call setgroups() in a more portable manner. |
181 | ||
aa6dc37c WD |
182 | * Improved file-related error messages to better indicate exactly |
183 | what pathname failed. (Wayne Davison) | |
2c873122 WD |
184 | |
185 | * Fixed some bugs in the handling of --delete and --exclude when | |
186 | using the --relative (-R) option. (Wayne Davison) | |
4a7ee79d | 187 | |
d89a3a31 S |
188 | * Fixed bug that prevented regular files from replacing |
189 | special files and caused a directory in --link-dest or | |
190 | --compare-dest to block the creation of a file with the | |
191 | same path. A directory still cannot be replaced by a | |
192 | regular file unless --delete specified. (J.W. Schultz) | |
193 | ||
6a7cc46c | 194 | * Detect and report when open or opendir succeed but read and |
52fa4d78 | 195 | readdir fail caused by network filesystem issues and truncated |
6a7cc46c S |
196 | files. (David Norwood, Michael Brown, J.W. Schultz) |
197 | ||
65653a65 WD |
198 | * Added a fix that should give ssh time to restore the tty settings |
199 | if the user presses Ctrl-C at an ssh password prompt. | |
200 | ||
89855e78 WD |
201 | INTERNAL: |
202 | ||
58665d23 | 203 | * Eliminated vestigial support for old versions that we stopped |
89855e78 WD |
204 | supporting. (J.W. Schultz) |
205 | ||
58665d23 | 206 | * Simplified some of the option-parsing code. (Wayne Davison) |
89855e78 | 207 | |
52e628a8 WD |
208 | * Some cleanup made to the exclude code, as well as some new |
209 | defines added to enhance readability. (Wayne Davison) | |
210 | ||
aa6dc37c WD |
211 | * Changed the protocol-version code so that it can interact at a |
212 | lower protocol level than the maximum supported by both sides. | |
213 | Added an undocumented option, --protocol=N, to force the value | |
214 | we advertise to the other side (primarily for testing purposes). | |
215 | (Wayne Davison) |
