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 | |
88b93c61 WD |
16 | - The "%o" (operation) value now has a third value besides "send" and |
17 | "recv": "del." (with trailing dot to make it 4 chars). This changes | |
18 | the way deletions are logged in the daemon's log file. | |
fd8571c2 | 19 | |
ac1541f4 WD |
20 | BUG FIXES: |
21 | ||
22 | - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3 | |
23 | was only treating it as a special token in an rsync include/exclude | |
24 | file). | |
25 | ||
8daa9925 WD |
26 | - The combination of --verbose and --dry-run now mentions the full list |
27 | of changes that would be output without --dry-run. | |
e30b1fb8 | 28 | |
1ed55e3e WD |
29 | - Avoid a mkdir warning when removing a directory in the destination |
30 | that already exists in the --backup-dir. | |
31 | ||
ac1541f4 WD |
32 | - An OS that has a binary mode for its files (such as cygwin0 needed |
33 | setmode(fd, O_BINARY) called on the temp-file we opened with | |
8daa9925 | 34 | mkstemp(). (Fix derived from the Cygwin's 2.6.3 rsync package.) |
4a888ae6 WD |
35 | |
36 | - Fixed a potential hang when verbosity is high, the client side is | |
37 | the sender, and the file-list is large. | |
ac1541f4 WD |
38 | |
39 | - We now check if the OS doesn't support using mknod() for creating | |
40 | FIFOs and sockets, and compile-in using mkfifo() and socket() when | |
41 | necessary. | |
42 | ||
740bab94 WD |
43 | - Fixed an off-by-one error in the handling of --max-delete=N. |
44 | ||
22f5bd5e | 45 | - One place in the code wasn't checking if fork() failed. |
5d54f339 | 46 | |
8daa9925 WD |
47 | - The "ignore nonreadable" daemon parameter used to erroneously affect |
48 | symlinks that pointed to a non-existent file. This has been fixed. | |
5b2f48da | 49 | |
ae09fb1f WD |
50 | - If the OS does not have lchown() and its chown() tries to set the |
51 | referent of a symlink (as it should), we no longer try to set the | |
52 | user and group of a symlink. | |
fbe2aba2 | 53 | |
ec626b3f WD |
54 | - The generator now properly runs the hard-link loop and the dir-time |
55 | rewriting loop after we're sure that the redo phase is complete. | |
56 | ||
da1b6eea WD |
57 | - When --backup was specified with --partial-dir=DIR (where DIR is a |
58 | relative path), the backup code was erroneously trying to backup a | |
59 | file that was put into the partial-dir. | |
ec626b3f | 60 | |
e30b1fb8 WD |
61 | - One call to flush_write_file() was not being checked for an error. |
62 | ||
63 | - The --no-relative option was not being sent from the client to a | |
64 | server sender. | |
65 | ||
66 | - If an rsync daemon specified "dont compress = ..." for a file and the | |
67 | client tried to specify --compress, the libz code was not handling a | |
68 | compression level of 0 properly. This could cause a transfer failure | |
69 | if the block-size for a file was large enough (i.e. rsync might have | |
70 | exited with an error for large files). | |
71 | ||
a897af2c | 72 | - If a daemon can't open the specified log file (i.e. syslog is not |
8daa9925 WD |
73 | being used), die without crashing. We also output an error about |
74 | the failure on stderr (which will only be seen if --no-detach was | |
a897af2c WD |
75 | specified). |
76 | ||
7b82b5ad | 77 | - A local transfer no longer duplicates all its include/exclude options |
8daa9925 WD |
78 | (since the forked process already has a copy of the exclude list, |
79 | there's no need to send them a set of duplicates). | |
7b82b5ad | 80 | |
ac1541f4 WD |
81 | ENHANCEMENTS: |
82 | ||
8f1b4f36 WD |
83 | - Rsync now supports popt's option aliases, which means that you can |
84 | use /etc/popt and/or ~/.popt to create your own option aliases. | |
85 | ||
da1b6eea WD |
86 | - Added the --delete-during (--del) option which will delete files |
87 | from on the receiving side incrementally as each directory in the | |
8daa9925 WD |
88 | transfer is being processed. This makes it more efficient than the |
89 | default, before-the-transfer behavior, which is now available as | |
90 | --delete-before (this is the default --delete-WHEN option that will | |
91 | be chosen if --delete or --delete-excluded is specified without a | |
92 | --delete-WHEN choice). All the --del* options infer --delete, so an | |
93 | rsync daemon that refuses "delete" will still refuse to allow any | |
94 | file-deleting options. | |
0752721d WD |
95 | |
96 | - All the --delete-WHEN options are now more memory efficient: | |
97 | Previously an entire duplicate set of file-list objects was created | |
98 | on the receiving side for the entire destination hierarchy. The new | |
0f7e31f7 | 99 | algorithm only creates one directory of objects at a time. |
da1b6eea | 100 | |
7a1b73b9 | 101 | - Added the --copy-dest option, which works like --link-dest except |
c3131af9 | 102 | that it includes copies of identical files. |
7a1b73b9 | 103 | |
22f5bd5e WD |
104 | - Added support for specifying multiple --compare-dest, --copy-dest, or |
105 | --link-dest options, but only of a single type. (Promoted from the | |
c3131af9 | 106 | patches dir and enhanced.) |
22f5bd5e | 107 | |
c3131af9 | 108 | - Added the --max-size option. (Promoted from the patches dir.) |
7a1b73b9 | 109 | |
18ea5dc0 | 110 | - The daemon-mode options were separated from the normal rsync options |
22f5bd5e WD |
111 | so that they can't be mixed together. This makes it impossible to |
112 | start a daemon that had improper default option values that could | |
8daa9925 | 113 | cause problems (e.g. a hang or an abort) when a client connects. |
18ea5dc0 | 114 | |
8f1b4f36 | 115 | - The --bwlimit option may now be used in combination with --daemon |
e30b1fb8 | 116 | to specify both a default value for the daemon side and a value |
8f1b4f36 WD |
117 | that cannot be exceeded by a user-specified --bwlimit option. |
118 | ||
c3131af9 | 119 | - Added the "port" parameter to the rsyncd.conf file. (Promoted from |
0f7e31f7 WD |
120 | the patches dir.) Also added "address". A command-line option |
121 | will take precedence over a config-file option, as expected. | |
c3131af9 | 122 | |
ac1541f4 WD |
123 | - In _exit_cleanup(): when we are exiting with a partially-received |
124 | file, we now flush any data in the write-cache before closing the | |
125 | partial file. | |
126 | ||
a8fd4161 | 127 | - The --inplace support was enhanced to work with --compare-dest, |
0f7e31f7 WD |
128 | --link-dest, and (the new) --copy-dest options. (Requires protocol |
129 | 29.) | |
a8fd4161 | 130 | |
9624b864 | 131 | - Added the --dirs (-d) option for an easier way to copy directories |
859fdaad WD |
132 | without recursion. |
133 | ||
134 | - Added the --list-only option which is mainly a way for the client to | |
135 | put the server into listing mode without needing to resort to any | |
8daa9925 WD |
136 | internal option kluges (e.g. the age-old use of "-r --exclude="/*/*" |
137 | for a non-recursive listing). This option is used automatically | |
138 | (behind the scenes) when a modern rsync speaks to a modern daemon, | |
139 | but may also be specified manually if you want to force the use of | |
140 | the --list-only option over a remote-shell connection. | |
859fdaad | 141 | |
9624b864 | 142 | - Added the --omit-dir-times (-O) option which will avoid updating the |
e30b1fb8 WD |
143 | modified time for directories when --times was specified. This |
144 | option will avoid an extra pass through the file-list at the end of | |
145 | the transfer (to tweak all the directory times), which can result in | |
7b82b5ad WD |
146 | an appreciable speedup for a really large transfer. (Promoted from |
147 | the patches dir.) | |
90fdd89a | 148 | |
9624b864 WD |
149 | - Added the --filter (-f) option and its helper option, -F. Filter |
150 | rules are an extension to the existing include/exclude handling | |
151 | that also supports nested filter files as well as per-directory | |
152 | filter files (like .cvsignore, but with full filter-rule parsing). | |
153 | This new option was chosen in order to ensure that all existing | |
154 | include/exclude processing remained 100% compatible with older | |
3723c048 WD |
155 | versions. Protocol 29 is needed for full filter-rule support, but |
156 | backward-compatible rules work with earlier protocol versions. | |
8daa9925 | 157 | (Promoted from the patches dir and enhanced.) |
9624b864 | 158 | |
da1b6eea WD |
159 | - Added the --delay-updates option that puts all updated files into |
160 | a temporary directory (by default ".~tmp~", but settable via the | |
161 | --partial-dir=DIR option) until the end of the transfer. This | |
162 | makes the updates a little more atomic for a large transfer. | |
163 | ||
e30b1fb8 WD |
164 | - If rsync is put into the background, any output from --progress is |
165 | reduced. | |
166 | ||
a897af2c WD |
167 | - Documented the "max verbosity" setting for rsyncd.conf. (This |
168 | setting was added a couple releases ago, but left undocumented.) | |
169 | ||
7b82b5ad | 170 | - The sender and the generator now double-check the file-list index |
8daa9925 WD |
171 | they are given, and refuse to try to do a file transfer on a |
172 | non-file index (since that would indicate that something had gone | |
173 | very wrong). | |
7b82b5ad | 174 | |
8daa9925 WD |
175 | - Added the --itemize-changes (-i) option, which is a way to output a |
176 | more detailed list of what files changed in any way and how they | |
177 | changed. The effect is the same as specifying a --log-format of | |
bd5b85db | 178 | "%i %n%L" (see the rsyncd.conf manpage). Works with --dry-run too. |
5b4e1f31 | 179 | |
3723c048 WD |
180 | - Added the --fuzzy option, which attempts to find a basis file for a |
181 | file that is being created from scratch. The current algorithm | |
182 | only looks in the destination directory for the created file, but | |
183 | it does attempt to find a match based on size/mod-time (in case the | |
184 | file was renamed with no other changes) as well as based on a fuzzy | |
185 | name-matching algorithm. This option requires protocol 29 because | |
186 | it needs the new file-sorting order. (Promoted from patches dir | |
187 | and enhanced.) | |
188 | ||
88b93c61 WD |
189 | - Added the --remove-sent-files option, which lets you move files |
190 | between systems. | |
191 | ||
8daa9925 | 192 | - Improved the option descriptions in the --help text. |
da1b6eea | 193 | |
8daa9925 | 194 | SUPPORT FILES: |
da1b6eea | 195 | |
8daa9925 WD |
196 | - Added atomic-rsync to the support dir: a perl script that will |
197 | transfer some files using rsync, and then move the updated files into | |
198 | place all at once at the end of the transfer. Only works when | |
199 | pulling, and uses --link-dest and a parallel hierarchy of files to | |
200 | effect its update. | |
da1b6eea | 201 | |
8daa9925 WD |
202 | - Added mnt-excl to the support dir: a perl script that takes the |
203 | /proc/mounts file and translates it into a set of excludes that will | |
204 | exclude all mount points (even mapped mounts to the same disk). The | |
205 | excludes are made relative to the specified source dir and properly | |
206 | anchored. | |
da1b6eea | 207 | |
8daa9925 WD |
208 | - Added savetransfer.c to the support dir: a C program that can make |
209 | a copy of all the data that flows over the wire. This lets you test | |
210 | for data corruption (by saving the data on both the sending side and | |
211 | the receiving side) or provides a way to help debug a protocol error. | |
cc17fbfe | 212 | |
8daa9925 WD |
213 | - Added rrsync to the support dir: this is my version of Joe Smith's |
214 | restricted rsync perl script. This helps to ensure that only certain | |
215 | rsync commands can be run by an ssh invocation. | |
a897af2c | 216 | |
a8fd4161 WD |
217 | INTERNAL: |
218 | ||
e30b1fb8 | 219 | - Added better checking of the checksum-header values that come over |
a8fd4161 WD |
220 | the socket. |
221 | ||
8daa9925 | 222 | - Merged a variety of file-deleting functions into a single function so |
e30b1fb8 WD |
223 | that it is easier to maintain. |
224 | ||
225 | - Improved the type of some variables (particularly blocksize vars) for | |
226 | consistency and proper size. | |
227 | ||
228 | - Got rid of the uint64 type (which we didn't need). | |
a8fd4161 | 229 | |
a897af2c WD |
230 | - Use a slightly more compatible set of core #include directives. |
231 | ||
232 | - Defined int32 in a way that ensures that the build dies if we can't | |
233 | find a variable with at least 32 bits. | |
234 | ||
5b4e1f31 WD |
235 | - The daemon's "read only" config item now sets an internal read_only |
236 | variable that makes extra sure that no write/delete calls on the | |
237 | read-only side can succeed. | |
238 | ||
0f7e31f7 WD |
239 | PROTOCOL DIFFERENCES FOR VERSION 29: |
240 | ||
bd5b85db WD |
241 | - A 16-bit flag-word is transmitted after every file-list index. This |
242 | indicates what is changing between the sender and the receiver. The | |
243 | generator now transmits an index and a flag-word to indicate when | |
8daa9925 WD |
244 | dirs and symlinks have changed (resorting to the old-style outputting |
245 | of local change-messages for older protocols). | |
bd5b85db | 246 | |
0f7e31f7 | 247 | - If --inplace is specified, the generator sends an extra byte after |
bd5b85db | 248 | the flag-word indicating what kind of basis file is being used for |
8daa9925 WD |
249 | the transfer (see the FNAMECMP_* defines). This information is used |
250 | to optimize the transfer when the basis file is not the destination. | |
0f7e31f7 WD |
251 | |
252 | - The sending of exclude names is done using filter-rule syntax. This | |
253 | means that all names have a prefixed rule indicator, even excludes | |
254 | (which used to be sent as a bare pattern, when possible). The -C | |
255 | option will include the per-dir .cvsignore merge file in the list of | |
256 | filter rules so it is positioned correctly (unlike in some older | |
257 | transfer scenarios). | |
258 | ||
8daa9925 WD |
259 | - Rsync sorts the filename list in a different way: it sorts the subdir |
260 | names after the non-subdir names for each dir's contents, and it | |
261 | always puts a dir's contents immediately after the dir's name in the | |
262 | list. (Previously an item named "foo.txt" would sort in between | |
86e97e17 | 263 | directory "foo/" and "foo/bar".) |
0f7e31f7 WD |
264 | |
265 | - When talking to a protocol 29 rsync daemon, a list-only request | |
266 | is able to note this before the options are sent over the wire, and | |
8daa9925 WD |
267 | the new --list-only option is encluded in the options sent over the |
268 | socket. | |
0f7e31f7 WD |
269 | |
270 | - When the --stats bytes are sent over the wire (or stored in a batch), | |
271 | they now include two elapsed-time values: one for how long it took to | |
272 | build the file-list, and one for how long it took to send it over the | |
273 | wire (each expressed in thousandths of a second). | |
274 | ||
28c54e81 | 275 | - When --delete-excluded is specified with some filter rules (AKA |
8daa9925 WD |
276 | excludes), a client sender will now initiate a send of the filter |
277 | rules to the receiver (older protocols used to omit the sending of | |
278 | excludes in this situation since there were no receiver-specific | |
279 | rules that survived --delete-excluded back then). Note that, as with | |
280 | all the filter-list sending, only items that are significant to the | |
281 | other side will actually be sent over the wire, so the filter-rule | |
282 | list is often empty in this scenario. | |
28c54e81 | 283 | |
0f7e31f7 WD |
284 | - A protocol-29 batch file includes a bit for the setting of the --dirs |
285 | option. Also, the shell script created by --write-batch will use the | |
286 | --filter option instead of --exclude-from to capture any filter rules. | |
287 | ||

288 | BUILD CHANGES: |
289 | ||
87ba7282 | 290 | - Handle an operating system that use mkdev() in place of makedev(). |
e30b1fb8 WD |
291 | |
292 | - Improved configure to better handle cross-compiling. |
