ac1541f4 | 1 | NEWS for rsync 2.6.4 (UNRELEASED) |
a8fd4161 | 2 | Protocol: 29 (changed) |
ac1541f4 WD |
3 | Changes since 2.6.3: |
4 | ||
fd8571c2 WD |
5 | OUTPUT CHANGES: |
6 | ||
7 | - When rsync deletes a directory and outputs a verbose message about | |
8 | it, it now appends a trailing slash to the name instead of (only | |
9 | sometimes) outputting a preceding "directory " string. | |
da1b6eea | 10 | |
a897af2c | 11 | - The --stats output will contain file-list time-statistics if both |
e30b1fb8 WD |
12 | sides are 2.6.4, or if the local side is 2.6.4 and the files are |
13 | being pushed (since the stats come from the sending side). | |
8daa9925 | 14 | (Requires protocol 29 for a pull.) |

16 | BUG FIXES: |
17 | ||
18 | - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3 | |
19 | was only treating it as a special token in an rsync include/exclude | |
20 | file). | |
21 | ||
8daa9925 WD |
22 | - The combination of --verbose and --dry-run now mentions the full list |
23 | of changes that would be output without --dry-run. | |
e30b1fb8 | 24 | |
1ed55e3e WD |
25 | - Avoid a mkdir warning when removing a directory in the destination |
26 | that already exists in the --backup-dir. | |
27 | ||
ac1541f4 WD |
28 | - An OS that has a binary mode for its files (such as cygwin0 needed |
29 | setmode(fd, O_BINARY) called on the temp-file we opened with | |
8daa9925 | 30 | mkstemp(). (Fix derived from the Cygwin's 2.6.3 rsync package.) |
4a888ae6 WD |
31 | |
32 | - Fixed a potential hang when verbosity is high, the client side is | |
33 | the sender, and the file-list is large. | |
ac1541f4 WD |
34 | |
35 | - We now check if the OS doesn't support using mknod() for creating | |
36 | FIFOs and sockets, and compile-in using mkfifo() and socket() when | |
37 | necessary. | |
38 | ||
740bab94 WD |
39 | - Fixed an off-by-one error in the handling of --max-delete=N. |
40 | ||
22f5bd5e | 41 | - One place in the code wasn't checking if fork() failed. |
5d54f339 | 42 | |
8daa9925 WD |
43 | - The "ignore nonreadable" daemon parameter used to erroneously affect |
44 | symlinks that pointed to a non-existent file. This has been fixed. | |
5b2f48da | 45 | |
ae09fb1f WD |
46 | - If the OS does not have lchown() and its chown() tries to set the |
47 | referent of a symlink (as it should), we no longer try to set the | |
48 | user and group of a symlink. | |
fbe2aba2 | 49 | |
ec626b3f WD |
50 | - The generator now properly runs the hard-link loop and the dir-time |
51 | rewriting loop after we're sure that the redo phase is complete. | |
52 | ||
da1b6eea WD |
53 | - When --backup was specified with --partial-dir=DIR (where DIR is a |
54 | relative path), the backup code was erroneously trying to backup a | |
55 | file that was put into the partial-dir. | |
ec626b3f | 56 | |
e30b1fb8 WD |
57 | - One call to flush_write_file() was not being checked for an error. |
58 | ||
59 | - The --no-relative option was not being sent from the client to a | |
60 | server sender. | |
61 | ||
62 | - If an rsync daemon specified "dont compress = ..." for a file and the | |
63 | client tried to specify --compress, the libz code was not handling a | |
64 | compression level of 0 properly. This could cause a transfer failure | |
65 | if the block-size for a file was large enough (i.e. rsync might have | |
66 | exited with an error for large files). | |
67 | ||
a897af2c | 68 | - If a daemon can't open the specified log file (i.e. syslog is not |
8daa9925 WD |
69 | being used), die without crashing. We also output an error about |
70 | the failure on stderr (which will only be seen if --no-detach was | |
a897af2c WD |
71 | specified). |
72 | ||
7b82b5ad | 73 | - A local transfer no longer duplicates all its include/exclude options |
8daa9925 WD |
74 | (since the forked process already has a copy of the exclude list, |
75 | there's no need to send them a set of duplicates). | |
7b82b5ad | 76 | |
ac1541f4 WD |
77 | ENHANCEMENTS: |
78 | ||
8f1b4f36 WD |
79 | - Rsync now supports popt's option aliases, which means that you can |
80 | use /etc/popt and/or ~/.popt to create your own option aliases. | |
81 | ||
da1b6eea WD |
82 | - Added the --delete-during (--del) option which will delete files |
83 | from on the receiving side incrementally as each directory in the | |
8daa9925 WD |
84 | transfer is being processed. This makes it more efficient than the |
85 | default, before-the-transfer behavior, which is now available as | |
86 | --delete-before (this is the default --delete-WHEN option that will | |
87 | be chosen if --delete or --delete-excluded is specified without a | |
88 | --delete-WHEN choice). All the --del* options infer --delete, so an | |
89 | rsync daemon that refuses "delete" will still refuse to allow any | |
90 | file-deleting options. | |
0752721d WD |
91 | |
92 | - All the --delete-WHEN options are now more memory efficient: | |
93 | Previously an entire duplicate set of file-list objects was created | |
94 | on the receiving side for the entire destination hierarchy. The new | |
0f7e31f7 | 95 | algorithm only creates one directory of objects at a time. |
da1b6eea | 96 | |
7a1b73b9 | 97 | - Added the --copy-dest option, which works like --link-dest except |
c3131af9 | 98 | that it includes copies of identical files. |
7a1b73b9 | 99 | |
22f5bd5e WD |
100 | - Added support for specifying multiple --compare-dest, --copy-dest, or |
101 | --link-dest options, but only of a single type. (Promoted from the | |
c3131af9 | 102 | patches dir and enhanced.) |
22f5bd5e | 103 | |
c3131af9 | 104 | - Added the --max-size option. (Promoted from the patches dir.) |
7a1b73b9 | 105 | |
18ea5dc0 | 106 | - The daemon-mode options were separated from the normal rsync options |
22f5bd5e WD |
107 | so that they can't be mixed together. This makes it impossible to |
108 | start a daemon that had improper default option values that could | |
8daa9925 | 109 | cause problems (e.g. a hang or an abort) when a client connects. |
18ea5dc0 | 110 | |
8f1b4f36 | 111 | - The --bwlimit option may now be used in combination with --daemon |
e30b1fb8 | 112 | to specify both a default value for the daemon side and a value |
8f1b4f36 WD |
113 | that cannot be exceeded by a user-specified --bwlimit option. |
114 | ||
c3131af9 | 115 | - Added the "port" parameter to the rsyncd.conf file. (Promoted from |
0f7e31f7 WD |
116 | the patches dir.) Also added "address". A command-line option |
117 | will take precedence over a config-file option, as expected. | |
c3131af9 | 118 | |
ac1541f4 WD |
119 | - In _exit_cleanup(): when we are exiting with a partially-received |
120 | file, we now flush any data in the write-cache before closing the | |
121 | partial file. | |
122 | ||
a8fd4161 | 123 | - The --inplace support was enhanced to work with --compare-dest, |
0f7e31f7 WD |
124 | --link-dest, and (the new) --copy-dest options. (Requires protocol |
125 | 29.) | |
a8fd4161 | 126 | |
9624b864 | 127 | - Added the --dirs (-d) option for an easier way to copy directories |
859fdaad WD |
128 | without recursion. |
129 | ||
130 | - Added the --list-only option which is mainly a way for the client to | |
131 | put the server into listing mode without needing to resort to any | |
8daa9925 WD |
132 | internal option kluges (e.g. the age-old use of "-r --exclude="/*/*" |
133 | for a non-recursive listing). This option is used automatically | |
134 | (behind the scenes) when a modern rsync speaks to a modern daemon, | |
135 | but may also be specified manually if you want to force the use of | |
136 | the --list-only option over a remote-shell connection. | |
859fdaad | 137 | |
9624b864 | 138 | - Added the --omit-dir-times (-O) option which will avoid updating the |
e30b1fb8 WD |
139 | modified time for directories when --times was specified. This |
140 | option will avoid an extra pass through the file-list at the end of | |
141 | the transfer (to tweak all the directory times), which can result in | |
7b82b5ad WD |
142 | an appreciable speedup for a really large transfer. (Promoted from |
143 | the patches dir.) | |
90fdd89a | 144 | |
9624b864 WD |
145 | - Added the --filter (-f) option and its helper option, -F. Filter |
146 | rules are an extension to the existing include/exclude handling | |
147 | that also supports nested filter files as well as per-directory | |
148 | filter files (like .cvsignore, but with full filter-rule parsing). | |
149 | This new option was chosen in order to ensure that all existing | |
150 | include/exclude processing remained 100% compatible with older | |
3723c048 WD |
151 | versions. Protocol 29 is needed for full filter-rule support, but |
152 | backward-compatible rules work with earlier protocol versions. | |
8daa9925 | 153 | (Promoted from the patches dir and enhanced.) |
9624b864 | 154 | |
da1b6eea WD |
155 | - Added the --delay-updates option that puts all updated files into |
156 | a temporary directory (by default ".~tmp~", but settable via the | |
157 | --partial-dir=DIR option) until the end of the transfer. This | |
158 | makes the updates a little more atomic for a large transfer. | |
159 | ||
e30b1fb8 WD |
160 | - If rsync is put into the background, any output from --progress is |
161 | reduced. | |
162 | ||
a897af2c WD |
163 | - Documented the "max verbosity" setting for rsyncd.conf. (This |
164 | setting was added a couple releases ago, but left undocumented.) | |
165 | ||
7b82b5ad | 166 | - The sender and the generator now double-check the file-list index |
8daa9925 WD |
167 | they are given, and refuse to try to do a file transfer on a |
168 | non-file index (since that would indicate that something had gone | |
169 | very wrong). | |
7b82b5ad | 170 | |
8daa9925 WD |
171 | - Added the --itemize-changes (-i) option, which is a way to output a |
172 | more detailed list of what files changed in any way and how they | |
173 | changed. The effect is the same as specifying a --log-format of | |
bd5b85db | 174 | "%i %n%L" (see the rsyncd.conf manpage). Works with --dry-run too. |
5b4e1f31 | 175 | |
3723c048 WD |
176 | - Added the --fuzzy option, which attempts to find a basis file for a |
177 | file that is being created from scratch. The current algorithm | |
178 | only looks in the destination directory for the created file, but | |
179 | it does attempt to find a match based on size/mod-time (in case the | |
180 | file was renamed with no other changes) as well as based on a fuzzy | |
181 | name-matching algorithm. This option requires protocol 29 because | |
182 | it needs the new file-sorting order. (Promoted from patches dir | |
183 | and enhanced.) | |
184 | ||
8daa9925 | 185 | - Improved the option descriptions in the --help text. |
da1b6eea | 186 | |
8daa9925 | 187 | SUPPORT FILES: |
da1b6eea | 188 | |
8daa9925 WD |
189 | - Added atomic-rsync to the support dir: a perl script that will |
190 | transfer some files using rsync, and then move the updated files into | |
191 | place all at once at the end of the transfer. Only works when | |
192 | pulling, and uses --link-dest and a parallel hierarchy of files to | |
193 | effect its update. | |
da1b6eea | 194 | |
8daa9925 WD |
195 | - Added mnt-excl to the support dir: a perl script that takes the |
196 | /proc/mounts file and translates it into a set of excludes that will | |
197 | exclude all mount points (even mapped mounts to the same disk). The | |
198 | excludes are made relative to the specified source dir and properly | |
199 | anchored. | |
da1b6eea | 200 | |
8daa9925 WD |
201 | - Added savetransfer.c to the support dir: a C program that can make |
202 | a copy of all the data that flows over the wire. This lets you test | |
203 | for data corruption (by saving the data on both the sending side and | |
204 | the receiving side) or provides a way to help debug a protocol error. | |
cc17fbfe | 205 | |
8daa9925 WD |
206 | - Added rrsync to the support dir: this is my version of Joe Smith's |
207 | restricted rsync perl script. This helps to ensure that only certain | |
208 | rsync commands can be run by an ssh invocation. | |
a897af2c | 209 | |
a8fd4161 WD |
210 | INTERNAL: |
211 | ||
e30b1fb8 | 212 | - Added better checking of the checksum-header values that come over |
a8fd4161 WD |
213 | the socket. |
214 | ||
8daa9925 | 215 | - Merged a variety of file-deleting functions into a single function so |
e30b1fb8 WD |
216 | that it is easier to maintain. |
217 | ||
218 | - Improved the type of some variables (particularly blocksize vars) for | |
219 | consistency and proper size. | |
220 | ||
221 | - Got rid of the uint64 type (which we didn't need). | |
a8fd4161 | 222 | |
a897af2c WD |
223 | - Use a slightly more compatible set of core #include directives. |
224 | ||
225 | - Defined int32 in a way that ensures that the build dies if we can't | |
226 | find a variable with at least 32 bits. | |
227 | ||
5b4e1f31 WD |
228 | - The daemon's "read only" config item now sets an internal read_only |
229 | variable that makes extra sure that no write/delete calls on the | |
230 | read-only side can succeed. | |
231 | ||
0f7e31f7 WD |
232 | PROTOCOL DIFFERENCES FOR VERSION 29: |
233 | ||
bd5b85db WD |
234 | - A 16-bit flag-word is transmitted after every file-list index. This |
235 | indicates what is changing between the sender and the receiver. The | |
236 | generator now transmits an index and a flag-word to indicate when | |
8daa9925 WD |
237 | dirs and symlinks have changed (resorting to the old-style outputting |
238 | of local change-messages for older protocols). | |
bd5b85db | 239 | |
0f7e31f7 | 240 | - If --inplace is specified, the generator sends an extra byte after |
bd5b85db | 241 | the flag-word indicating what kind of basis file is being used for |
8daa9925 WD |
242 | the transfer (see the FNAMECMP_* defines). This information is used |
243 | to optimize the transfer when the basis file is not the destination. | |
0f7e31f7 WD |
244 | |
245 | - The sending of exclude names is done using filter-rule syntax. This | |
246 | means that all names have a prefixed rule indicator, even excludes | |
247 | (which used to be sent as a bare pattern, when possible). The -C | |
248 | option will include the per-dir .cvsignore merge file in the list of | |
249 | filter rules so it is positioned correctly (unlike in some older | |
250 | transfer scenarios). | |
251 | ||
8daa9925 WD |
252 | - Rsync sorts the filename list in a different way: it sorts the subdir |
253 | names after the non-subdir names for each dir's contents, and it | |
254 | always puts a dir's contents immediately after the dir's name in the | |
255 | list. (Previously an item named "foo.txt" would sort in between | |
86e97e17 | 256 | directory "foo/" and "foo/bar".) |
0f7e31f7 WD |
257 | |
258 | - When talking to a protocol 29 rsync daemon, a list-only request | |
259 | is able to note this before the options are sent over the wire, and | |
8daa9925 WD |
260 | the new --list-only option is encluded in the options sent over the |
261 | socket. | |
0f7e31f7 WD |
262 | |
263 | - When the --stats bytes are sent over the wire (or stored in a batch), | |
264 | they now include two elapsed-time values: one for how long it took to | |
265 | build the file-list, and one for how long it took to send it over the | |
266 | wire (each expressed in thousandths of a second). | |
267 | ||
28c54e81 | 268 | - When --delete-excluded is specified with some filter rules (AKA |
8daa9925 WD |
269 | excludes), a client sender will now initiate a send of the filter |
270 | rules to the receiver (older protocols used to omit the sending of | |
271 | excludes in this situation since there were no receiver-specific | |
272 | rules that survived --delete-excluded back then). Note that, as with | |
273 | all the filter-list sending, only items that are significant to the | |
274 | other side will actually be sent over the wire, so the filter-rule | |
275 | list is often empty in this scenario. | |
28c54e81 | 276 | |
0f7e31f7 WD |
277 | - A protocol-29 batch file includes a bit for the setting of the --dirs |
278 | option. Also, the shell script created by --write-batch will use the | |
279 | --filter option instead of --exclude-from to capture any filter rules. | |

281 | BUILD CHANGES: |
282 | ||
87ba7282 | 283 | - Handle an operating system that use mkdev() in place of makedev(). |
e30b1fb8 WD |
284 | |
285 | - Improved configure to better handle cross-compiling. |
