1 | NEWS for rsync 2.6.1 (UNRELEASED) |
2 | Protocol: 27 (unchanged) | |
3 | Changes since 2.6.0: | |
4 | ||
5 | ENHANCEMENTS: | |
6 | ||
7 | * The RSYNC_PROXY environment variable can now contain a | |
8 | "USER:PASS@" prefix before the "HOST:PORT" information. | |
9 | (Bardur Arantsson) | |
10 | ||
1a62c49d WD |
11 | * Lower memory use and more optimal transfer of file data. |
12 | (see the INTERNAL section). | |
13 | ||
823edc68 WD |
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 | |
29 | the wire. | |
30 | ||
e7bef922 WD |
31 | * Fixed a byte-order problem in --batch-mode on big-endian |
32 | machines. (Jay Fenlason) | |
33 | ||
823edc68 WD |
34 | INTERNAL: |
35 | ||
86c4601e | 36 | * Most of the I/O is now buffered, which results in a pretty |
a18381ac | 37 | large speedup when running under MS Windows. (Craig Barratt) |
823edc68 WD |
38 | |
39 | * Optimizations to the name-handling/comparing code have made | |
40 | some significant reductions in user CPU time for large file | |
41 | sets. (Wayne Davison) | |
42 | ||
31e7451a WD |
43 | * Some variable-type cleanup that makes the code more consistent. |
44 | (Wayne Davison) | |
45 | ||
279b1c1e S |
46 | * Reduced memory requirements of hard link preservation. |
47 | (J.W. Schultz) | |
48 | ||
1a62c49d | 49 | * Got rid of support for protocol versions 17 and 18 (which are |
aa953c32 WD |
50 | both over 6 years old). |
51 | ||
1a62c49d WD |
52 | * More optimal data transmission for --hard-links (protocol 28). |
53 | ||
54 | * More optimal data transmission for --checksum (protocol 28). | |
55 | ||
56 | * Less memory used for holding --checksum data. | |

276877cf | 59 | NEWS for rsync 2.6.0 (1 Jan 2004) |
195bd906 | 60 | Protocol: 27 (changed) |
276877cf | 61 | Changes since 2.5.7: |
89855e78 WD |
62 | |
63 | ENHANCEMENTS: | |
64 | ||
e636af6b WD |
65 | * "ssh" is now the default remote shell for rsync. If you want to |
66 | change this, configure like this: "./configure --with-rsh=rsh". | |
67 | ||
58665d23 | 68 | * Added --files-from, --no-relative, --no-implied-dirs, and --from0. |
89855e78 | 69 | Note that --from0 affects the line-ending character for all the |
d00daf1f | 70 | files read by the --*-from options. (Wayne Davison) |
89855e78 | 71 | |
9e83fa99 | 72 | * Length of csum2 is now per-file starting with protocol version |
58665d23 | 73 | 27. (J.W. Schultz) |
195bd906 | 74 | |
9e83fa99 WD |
75 | * Per-file dynamic block size is now sqrt(file length). The |
76 | per-file checksum size is determined according to an algorithm | |
77 | provided by Donovan Baarda which reduces the probability of rsync | |
78 | algorithm corrupting data and falling back using the whole md4 | |
58665d23 | 79 | checksums. (J.W. Schultz, Donovan Baarda) |
195bd906 | 80 | |
727fa368 WD |
81 | * The --stats option no longer includes the (debug) malloc summary |
82 | unless the verbose option was specified at least twice. | |
83 | ||
d00daf1f WD |
84 | * Added a new error/warning code for when files vanish from the |
85 | sending side. Made vanished source files not interfere with the | |
86 | file-deletion pass when --delete-after was specified. | |
87 | ||
9e83fa99 WD |
88 | * Various trailing-info sections are now preceded by a newline. |
89 | ||
89855e78 WD |
90 | BUG FIXES: |
91 | ||
f2fe4903 WD |
92 | * Fixed several exclude/include matching bugs when using wild-cards. |
93 | This has a several user-visible effects, all of which make the | |
94 | matching more consistent and intuitive. This should hopefully not | |
95 | cause anyone problems since it makes the matching work more like | |
96 | what people are expecting. (Wayne Davison) | |
97 | ||
592f4696 WD |
98 | - A pattern with a "**" no longer causes a "*" to match slashes. |
99 | For example, with "/*/foo/**", "foo" must be 2 levels deep. | |
faf11086 WD |
100 | [If your string has BOTH "*" and "**" wildcards, changing the |
101 | "*" wildcards to "**" will provide the old behavior in all | |
102 | versions.] | |
592f4696 | 103 | |
52fa4d78 WD |
104 | - "**/foo" now matches at the base of the transfer (like /foo |
105 | does). [Use "/**/foo" to get the old behavior in all versions.] | |
f2fe4903 | 106 | |
52fa4d78 | 107 | - A non-anchored wildcard term floats to match beyond the base of |
f2fe4903 | 108 | the transfer. E.g. "CVS/R*" matches at the end of the path, |
52fa4d78 WD |
109 | just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*" |
110 | to get the old behavior in all versions.] | |
f2fe4903 WD |
111 | |
112 | - Including a "**" in the match term causes it to be matched | |
113 | against the entire path, not just the name portion, even if | |
114 | there aren't any interior slashes in the term. E.g. "foo**bar" | |
115 | would exclude "/path/foo-bar" (just like before) as well as | |
52fa4d78 WD |
116 | "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the |
117 | old behavior in all versions.] | |
f2fe4903 | 118 | |
52e628a8 WD |
119 | * The exclude list specified in the daemon's config file is now |
120 | properly applied to the pulled items no matter how deep the | |
d00daf1f | 121 | user's file-args are in the source tree. (Wayne Davison) |
52e628a8 | 122 | |
da2bcdd1 | 123 | * For protocol version >= 27, mdfour_tail() is called when the |
58665d23 WD |
124 | block size (including checksum_seed) is a multiple of 64. |
125 | Previously it was not called, giving the wrong MD4 checksum. | |
126 | (Craig Barratt) | |
256a9e37 | 127 | |
da2bcdd1 | 128 | * For protocol version >= 27, a 64 bit bit counter is used in |
58665d23 WD |
129 | mdfour.c as required by the RFC. Previously only a 32 bit bit |
130 | counter was used, causing incorrect MD4 file checksums for | |
131 | file sizes >= 512MB - 4. (Craig Barratt) | |
195bd906 | 132 | |
da2bcdd1 | 133 | * Fixed a crash bug when interacting with older rsync versions and |
89855e78 WD |
134 | multiple files of the same name are destined for the same dir. |
135 | (Wayne Davison) | |
136 | ||
58665d23 | 137 | * Keep tmp names from overflowing MAXPATHLEN. |
89855e78 | 138 | |
da2bcdd1 | 139 | * Make --link-dest honor the absence of -p, -o, and -g. |
fab1f889 | 140 | |
8113a033 WD |
141 | * Made rsync treat a trailing slash in the destination in a more |
142 | consistent manner. | |
143 | ||
9b746433 | 144 | * Fixed file I/O error detection. (John Van Essen) |
fab1f889 | 145 | |
256a9e37 WD |
146 | * Fixed bogus "malformed address {hostname}" message in rsyncd log |
147 | when checking IP address against hostnames from "hosts allow" | |
148 | and "hosts deny" parameters in config file. | |
149 | ||
150 | * Print heap statistics when verbose >= 2 instead of when >= 1. | |
151 | ||
90045413 WD |
152 | * Fixed a compression (-z) bug when syncing a mostly-matching file |
153 | that contains already-compressed data. (Yasuoka Masahiko and | |
154 | Wayne Davison) | |
155 | ||
d594399c WD |
156 | * Fixed a bug in the --backup code that could cause deleted files |
157 | to not get backed up. | |
158 | ||
860bdd45 WD |
159 | * When the backup code makes new directories, create them with mode |
160 | 0700 instead of 0755 (since the directory permissions in the | |
161 | backup tree are not yet copied from the main tree). | |
162 | ||
2c873122 WD |
163 | * Call setgroups() in a more portable manner. |
164 | ||
aa6dc37c WD |
165 | * Improved file-related error messages to better indicate exactly |
166 | what pathname failed. (Wayne Davison) | |
2c873122 WD |
167 | |
168 | * Fixed some bugs in the handling of --delete and --exclude when | |
169 | using the --relative (-R) option. (Wayne Davison) | |
4a7ee79d | 170 | |
d89a3a31 S |
171 | * Fixed bug that prevented regular files from replacing |
172 | special files and caused a directory in --link-dest or | |
173 | --compare-dest to block the creation of a file with the | |
174 | same path. A directory still cannot be replaced by a | |
175 | regular file unless --delete specified. (J.W. Schultz) | |
176 | ||
6a7cc46c | 177 | * Detect and report when open or opendir succeed but read and |
52fa4d78 | 178 | readdir fail caused by network filesystem issues and truncated |
6a7cc46c S |
179 | files. (David Norwood, Michael Brown, J.W. Schultz) |
180 | ||
65653a65 WD |
181 | * Added a fix that should give ssh time to restore the tty settings |
182 | if the user presses Ctrl-C at an ssh password prompt. | |
183 | ||
89855e78 WD |
184 | INTERNAL: |
185 | ||
58665d23 | 186 | * Eliminated vestigial support for old versions that we stopped |
89855e78 WD |
187 | supporting. (J.W. Schultz) |
188 | ||
58665d23 | 189 | * Simplified some of the option-parsing code. (Wayne Davison) |
89855e78 | 190 | |
52e628a8 WD |
191 | * Some cleanup made to the exclude code, as well as some new |
192 | defines added to enhance readability. (Wayne Davison) | |
193 | ||
aa6dc37c WD |
194 | * Changed the protocol-version code so that it can interact at a |
195 | lower protocol level than the maximum supported by both sides. | |
196 | Added an undocumented option, --protocol=N, to force the value | |
197 | we advertise to the other side (primarily for testing purposes). | |
198 | (Wayne Davison) |
