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.) |
591b908f | 15 | |
ea38b5af WD |
16 | - The "%o" (operation) log-format escape now has a third value (besides |
17 | "send" and "recv"): "del." (with trailing dot to make it 4 chars). | |
18 | This changes the way deletions are logged in the daemon's log file. | |
19 | ||
20 | - When the --log-format option is combined with --verbose, rsync now | |
21 | avoids outputting the name of the file twice in most circumstances. | |
22 | As long as the --log-format item does not refer to any post-transfer | |
23 | items (such as %b or %c), the --log-format message is output prior to | |
24 | the transfer with --verbose being the equivalent of a --log-format of | |
25 | '%n%L' (which outputs the name and any symlink info). If the log | |
26 | output must occur after the transfer to be complete, the only time | |
27 | the name is also output prior to the transfer is when --progress was | |
28 | specified (so that the name will precede the progress stats, and the | |
29 | full --log-format output will come after). | |
fd8571c2 | 30 | |
ac1541f4 WD |
31 | BUG FIXES: |
32 | ||
33 | - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3 | |
34 | was only treating it as a special token in an rsync include/exclude | |
35 | file). | |
36 | ||
8daa9925 WD |
37 | - The combination of --verbose and --dry-run now mentions the full list |
38 | of changes that would be output without --dry-run. | |
e30b1fb8 | 39 | |
1ed55e3e WD |
40 | - Avoid a mkdir warning when removing a directory in the destination |
41 | that already exists in the --backup-dir. | |
42 | ||
8c577323 | 43 | - An OS that has a binary mode for its files (such as cygwin) needed |
ac1541f4 | 44 | setmode(fd, O_BINARY) called on the temp-file we opened with |
8c577323 | 45 | mkstemp(). (Fix derived from the cygwin's 2.6.3 rsync package.) |
4a888ae6 WD |
46 | |
47 | - Fixed a potential hang when verbosity is high, the client side is | |
48 | the sender, and the file-list is large. | |
ac1541f4 WD |
49 | |
50 | - We now check if the OS doesn't support using mknod() for creating | |
51 | FIFOs and sockets, and compile-in using mkfifo() and socket() when | |
52 | necessary. | |
53 | ||
740bab94 WD |
54 | - Fixed an off-by-one error in the handling of --max-delete=N. |
55 | ||
22f5bd5e | 56 | - One place in the code wasn't checking if fork() failed. |
5d54f339 | 57 | |
8daa9925 WD |
58 | - The "ignore nonreadable" daemon parameter used to erroneously affect |
59 | symlinks that pointed to a non-existent file. This has been fixed. | |
5b2f48da | 60 | |
8c577323 WD |
61 | - If the OS does not have lchown() and a chown() of a symlink will |
62 | affect the referent of a symlink (as it should), we no longer try | |
63 | to set the user and group of a symlink. | |
fbe2aba2 | 64 | |
ec626b3f WD |
65 | - The generator now properly runs the hard-link loop and the dir-time |
66 | rewriting loop after we're sure that the redo phase is complete. | |
67 | ||
da1b6eea WD |
68 | - When --backup was specified with --partial-dir=DIR (where DIR is a |
69 | relative path), the backup code was erroneously trying to backup a | |
70 | file that was put into the partial-dir. | |
ec626b3f | 71 | |
f1223831 WD |
72 | - If a file gets resent in a single transfer and the --backup option is |
73 | enabled along with --inplace, rsync no longer performs a duplicate | |
74 | backup (it used to overwrite the first backup with the failed file). | |
75 | ||
e30b1fb8 WD |
76 | - One call to flush_write_file() was not being checked for an error. |
77 | ||
78 | - The --no-relative option was not being sent from the client to a | |
79 | server sender. | |
80 | ||
81 | - If an rsync daemon specified "dont compress = ..." for a file and the | |
82 | client tried to specify --compress, the libz code was not handling a | |
83 | compression level of 0 properly. This could cause a transfer failure | |
8c577323 | 84 | if the block-size for a file was large enough (e.g. rsync might have |
e30b1fb8 WD |
85 | exited with an error for large files). |
86 | ||
8db3106e WD |
87 | - Fixed a bug that would sometimes surface when using --compress and |
88 | sending a file with a block-size larger than 64K (either manually | |
89 | specified, or computed due to the file being really large). Prior | |
bbbb44ee | 90 | versions of rsync would sometimes fail to decompress the data |
8db3106e WD |
91 | properly, and thus the transferred file would fail its verification. |
92 | ||
a897af2c | 93 | - If a daemon can't open the specified log file (i.e. syslog is not |
8daa9925 WD |
94 | being used), die without crashing. We also output an error about |
95 | the failure on stderr (which will only be seen if --no-detach was | |
a897af2c WD |
96 | specified). |
97 | ||
7b82b5ad | 98 | - A local transfer no longer duplicates all its include/exclude options |
8daa9925 WD |
99 | (since the forked process already has a copy of the exclude list, |
100 | there's no need to send them a set of duplicates). | |
7b82b5ad | 101 | |
7b97c388 WD |
102 | - When --progress is specified, the output of items that the generator |
103 | is creating (e.g. dirs, symlinks) is now integrated into the progress | |
8c577323 | 104 | output without overlapping it. (Requires protocol 29.) |
7b97c388 | 105 | |
e6f5ac11 | 106 | - When --timeout is specified, lulls that occur in the transfer while |
fef101a5 WD |
107 | the generator is doing work that does not generate socket traffic |
108 | (looking for changed files, deleting files, doing directory-time | |
109 | touch-ups, etc.) will cause a new keep-alive packet to be sent that | |
110 | should keep the transfer going as long as the generator continues to | |
111 | make progress. (Requires protocol 29.) | |
47780ddf WD |
112 | |
113 | - The stat size of a device is not added to the total file size of the | |
e6f5ac11 | 114 | items in the transfer since the size might be undefined on some OSes. |
47780ddf | 115 | |
472135e0 WD |
116 | - Fixed a problem with refused-option messages sometimes not making it |
117 | back to the client side when a remote --files-from was in effect and | |
118 | the daemon was the receiver. | |
119 | ||
ac1541f4 WD |
120 | ENHANCEMENTS: |
121 | ||
8f1b4f36 WD |
122 | - Rsync now supports popt's option aliases, which means that you can |
123 | use /etc/popt and/or ~/.popt to create your own option aliases. | |
124 | ||
da1b6eea | 125 | - Added the --delete-during (--del) option which will delete files |
bbbb44ee | 126 | from the receiving side incrementally as each directory in the |
8daa9925 WD |
127 | transfer is being processed. This makes it more efficient than the |
128 | default, before-the-transfer behavior, which is now available as | |
bbbb44ee | 129 | --delete-before (and is still the default --delete-WHEN option that |
8c577323 WD |
130 | will be chosen if --delete or --delete-excluded is specified without |
131 | a --delete-WHEN choice). All the --del* options infer --delete, so | |
132 | an rsync daemon that refuses "delete" will still refuse to allow any | |
8daa9925 | 133 | file-deleting options. |
0752721d WD |
134 | |
135 | - All the --delete-WHEN options are now more memory efficient: | |
136 | Previously an entire duplicate set of file-list objects was created | |
137 | on the receiving side for the entire destination hierarchy. The new | |
bbbb44ee WD |
138 | algorithm only creates one directory of objects at a time (for files |
139 | inside the transfer). | |
da1b6eea | 140 | |
e9973668 WD |
141 | - Added support for specifying multiple --compare-dest or --link-dest |
142 | options, but only of a single type. (Promoted from the patches dir | |
143 | and enhanced.) | |
22f5bd5e | 144 | |
c3131af9 | 145 | - Added the --max-size option. (Promoted from the patches dir.) |
7a1b73b9 | 146 | |
18ea5dc0 | 147 | - The daemon-mode options were separated from the normal rsync options |
22f5bd5e WD |
148 | so that they can't be mixed together. This makes it impossible to |
149 | start a daemon that had improper default option values that could | |
8c577323 | 150 | cause problems when a client connects (e.g. a hang or an abort). |
18ea5dc0 | 151 | |
8f1b4f36 | 152 | - The --bwlimit option may now be used in combination with --daemon |
e30b1fb8 | 153 | to specify both a default value for the daemon side and a value |
8f1b4f36 WD |
154 | that cannot be exceeded by a user-specified --bwlimit option. |
155 | ||
c3131af9 | 156 | - Added the "port" parameter to the rsyncd.conf file. (Promoted from |
0f7e31f7 WD |
157 | the patches dir.) Also added "address". A command-line option |
158 | will take precedence over a config-file option, as expected. | |
c3131af9 | 159 | |
ac1541f4 WD |
160 | - In _exit_cleanup(): when we are exiting with a partially-received |
161 | file, we now flush any data in the write-cache before closing the | |
162 | partial file. | |
163 | ||
e9973668 WD |
164 | - The --inplace support was enhanced to work with --compare-dest and |
165 | --link-dest. (Requires protocol 29.) | |
a8fd4161 | 166 | |
9624b864 | 167 | - Added the --dirs (-d) option for an easier way to copy directories |
859fdaad WD |
168 | without recursion. |
169 | ||
bbbb44ee | 170 | - Added the --list-only option, which is mainly a way for the client to |
859fdaad | 171 | put the server into listing mode without needing to resort to any |
8daa9925 WD |
172 | internal option kluges (e.g. the age-old use of "-r --exclude="/*/*" |
173 | for a non-recursive listing). This option is used automatically | |
174 | (behind the scenes) when a modern rsync speaks to a modern daemon, | |
175 | but may also be specified manually if you want to force the use of | |
176 | the --list-only option over a remote-shell connection. | |
859fdaad | 177 | |
8c577323 WD |
178 | - Added the --omit-dir-times (-O) option, which will avoid updating |
179 | the modified time for directories when --times was specified. This | |
e30b1fb8 WD |
180 | option will avoid an extra pass through the file-list at the end of |
181 | the transfer (to tweak all the directory times), which can result in | |
7b82b5ad WD |
182 | an appreciable speedup for a really large transfer. (Promoted from |
183 | the patches dir.) | |
90fdd89a | 184 | |
9624b864 WD |
185 | - Added the --filter (-f) option and its helper option, -F. Filter |
186 | rules are an extension to the existing include/exclude handling | |
187 | that also supports nested filter files as well as per-directory | |
188 | filter files (like .cvsignore, but with full filter-rule parsing). | |
189 | This new option was chosen in order to ensure that all existing | |
190 | include/exclude processing remained 100% compatible with older | |
3723c048 WD |
191 | versions. Protocol 29 is needed for full filter-rule support, but |
192 | backward-compatible rules work with earlier protocol versions. | |
8daa9925 | 193 | (Promoted from the patches dir and enhanced.) |
9624b864 | 194 | |
da1b6eea WD |
195 | - Added the --delay-updates option that puts all updated files into |
196 | a temporary directory (by default ".~tmp~", but settable via the | |
197 | --partial-dir=DIR option) until the end of the transfer. This | |
198 | makes the updates a little more atomic for a large transfer. | |
199 | ||
e30b1fb8 WD |
200 | - If rsync is put into the background, any output from --progress is |
201 | reduced. | |
202 | ||
a897af2c WD |
203 | - Documented the "max verbosity" setting for rsyncd.conf. (This |
204 | setting was added a couple releases ago, but left undocumented.) | |
205 | ||
7b82b5ad | 206 | - The sender and the generator now double-check the file-list index |
8daa9925 WD |
207 | they are given, and refuse to try to do a file transfer on a |
208 | non-file index (since that would indicate that something had gone | |
209 | very wrong). | |
7b82b5ad | 210 | |
8daa9925 WD |
211 | - Added the --itemize-changes (-i) option, which is a way to output a |
212 | more detailed list of what files changed in any way and how they | |
213 | changed. The effect is the same as specifying a --log-format of | |
bd5b85db | 214 | "%i %n%L" (see the rsyncd.conf manpage). Works with --dry-run too. |
5b4e1f31 | 215 | |
3723c048 WD |
216 | - Added the --fuzzy option, which attempts to find a basis file for a |
217 | file that is being created from scratch. The current algorithm | |
218 | only looks in the destination directory for the created file, but | |
219 | it does attempt to find a match based on size/mod-time (in case the | |
220 | file was renamed with no other changes) as well as based on a fuzzy | |
221 | name-matching algorithm. This option requires protocol 29 because | |
222 | it needs the new file-sorting order. (Promoted from patches dir | |
223 | and enhanced.) | |
224 | ||
88b93c61 WD |
225 | - Added the --remove-sent-files option, which lets you move files |
226 | between systems. | |
227 | ||
472135e0 WD |
228 | - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal |
229 | enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6 | |
230 | literals in the rsync://HOST:PORT/PATH format.) | |
231 | ||
7b97c388 WD |
232 | - When building under windows, the default for --daemon is now to |
233 | avoid detaching, requiring the new --detach option to force rsync | |
234 | to detach. | |
235 | ||
8daa9925 | 236 | - Improved the option descriptions in the --help text. |
da1b6eea | 237 | |
8daa9925 | 238 | SUPPORT FILES: |
da1b6eea | 239 | |
8daa9925 WD |
240 | - Added atomic-rsync to the support dir: a perl script that will |
241 | transfer some files using rsync, and then move the updated files into | |
242 | place all at once at the end of the transfer. Only works when | |
243 | pulling, and uses --link-dest and a parallel hierarchy of files to | |
244 | effect its update. | |
da1b6eea | 245 | |
8daa9925 WD |
246 | - Added mnt-excl to the support dir: a perl script that takes the |
247 | /proc/mounts file and translates it into a set of excludes that will | |
248 | exclude all mount points (even mapped mounts to the same disk). The | |
249 | excludes are made relative to the specified source dir and properly | |
250 | anchored. | |
da1b6eea | 251 | |
8daa9925 WD |
252 | - Added savetransfer.c to the support dir: a C program that can make |
253 | a copy of all the data that flows over the wire. This lets you test | |
254 | for data corruption (by saving the data on both the sending side and | |
255 | the receiving side) or provides a way to help debug a protocol error. | |
cc17fbfe | 256 | |
8daa9925 WD |
257 | - Added rrsync to the support dir: this is my version of Joe Smith's |
258 | restricted rsync perl script. This helps to ensure that only certain | |
259 | rsync commands can be run by an ssh invocation. | |
a897af2c | 260 | |
a8fd4161 WD |
261 | INTERNAL: |
262 | ||
e30b1fb8 | 263 | - Added better checking of the checksum-header values that come over |
a8fd4161 WD |
264 | the socket. |
265 | ||
8daa9925 | 266 | - Merged a variety of file-deleting functions into a single function so |
e30b1fb8 WD |
267 | that it is easier to maintain. |
268 | ||
269 | - Improved the type of some variables (particularly blocksize vars) for | |
270 | consistency and proper size. | |
271 | ||
272 | - Got rid of the uint64 type (which we didn't need). | |
a8fd4161 | 273 | |
a897af2c WD |
274 | - Use a slightly more compatible set of core #include directives. |
275 | ||
276 | - Defined int32 in a way that ensures that the build dies if we can't | |
277 | find a variable with at least 32 bits. | |
278 | ||
5b4e1f31 WD |
279 | - The daemon's "read only" config item now sets an internal read_only |
280 | variable that makes extra sure that no write/delete calls on the | |
281 | read-only side can succeed. | |
282 | ||
0f7e31f7 WD |
283 | PROTOCOL DIFFERENCES FOR VERSION 29: |
284 | ||
bd5b85db WD |
285 | - A 16-bit flag-word is transmitted after every file-list index. This |
286 | indicates what is changing between the sender and the receiver. The | |
287 | generator now transmits an index and a flag-word to indicate when | |
33f839b3 WD |
288 | dirs and symlinks have changed (instead of producing a message), |
289 | which makes the outputting of the information more consistent and | |
290 | less prone to screen corruption (because either the receiver or the | |
291 | sender is now outputting all the file-change info). | |
bd5b85db | 292 | |
8c577323 WD |
293 | - If --inplace is specified, the generator flags any transfer that is |
294 | using an alternate basis file so that the sender can use the entire | |
f1223831 | 295 | basis file in the rsync algorithm (unlike a normal --inplace update). |
0f7e31f7 WD |
296 | |
297 | - The sending of exclude names is done using filter-rule syntax. This | |
298 | means that all names have a prefixed rule indicator, even excludes | |
299 | (which used to be sent as a bare pattern, when possible). The -C | |
300 | option will include the per-dir .cvsignore merge file in the list of | |
301 | filter rules so it is positioned correctly (unlike in some older | |
302 | transfer scenarios). | |
303 | ||
8daa9925 WD |
304 | - Rsync sorts the filename list in a different way: it sorts the subdir |
305 | names after the non-subdir names for each dir's contents, and it | |
306 | always puts a dir's contents immediately after the dir's name in the | |
307 | list. (Previously an item named "foo.txt" would sort in between | |
86e97e17 | 308 | directory "foo/" and "foo/bar".) |
0f7e31f7 WD |
309 | |
310 | - When talking to a protocol 29 rsync daemon, a list-only request | |
8c577323 WD |
311 | is able to note this before the options are sent over the wire and |
312 | the new --list-only option is included in the options. | |
0f7e31f7 WD |
313 | |
314 | - When the --stats bytes are sent over the wire (or stored in a batch), | |
315 | they now include two elapsed-time values: one for how long it took to | |
316 | build the file-list, and one for how long it took to send it over the | |
317 | wire (each expressed in thousandths of a second). | |
318 | ||
8c577323 WD |
319 | - When --delete-excluded is specified with some filter excludes, a |
320 | client sender will now initiate a send of the filter rules to the | |
321 | receiver (older protocols used to omit the sending of excludes in | |
322 | this situation since there were no receiver-specific rules that | |
323 | survived --delete-excluded back then). Note that, as with all the | |
324 | filter-list sending, only items that are significant to the other | |
325 | side will actually be sent over the wire, so the filter-rule list | |
326 | is often empty in this scenario. | |
28c54e81 | 327 | |
0f7e31f7 WD |
328 | - A protocol-29 batch file includes a bit for the setting of the --dirs |
329 | option. Also, the shell script created by --write-batch will use the | |
330 | --filter option instead of --exclude-from to capture any filter rules. | |
331 | ||
47780ddf | 332 | - An index equal to the file-list count is sent as a keep-alive packet |
fef101a5 | 333 | from the generator to the sender, which then forwards it on to the |
47780ddf WD |
334 | receiver. This normally invalid index is only a valid keep-alive |
335 | packet if the 16-bit flag-word that follows it contains a single bit | |
336 | (ITEM_IS_NEW, which is normally an illegal flag to appear alone). | |
337 | ||
ac1541f4 WD |
338 | BUILD CHANGES: |
339 | ||
87ba7282 | 340 | - Handle an operating system that use mkdev() in place of makedev(). |
e30b1fb8 WD |
341 | |
342 | - Improved configure to better handle cross-compiling. |
