2955529b | 1 | NEWS for rsync 3.0.0 (UNRELEASED) |
2dc3db2a | 2 | Protocol: 30 (changed) |
2955529b | 3 | Changes since 2.6.9: |
36f59b58 | 4 | |
44a7ba45 | 5 | NOTABLE CHANGES IN BEHAVIOR: |
4f3c1df6 | 6 | |
3f655768 WD |
7 | - The handling of implied directories when using --relative has changed to |
8 | send them as directories (e.g. no implied dir is ever sent as a symlink). | |
9 | This avoids unexpected behavior and should not adversely affect most | |
2f39f112 WD |
10 | people. If you're one of those rare individuals who relied upon having |
11 | an implied dir be duplicated as a symlink, you should specify the | |
12 | transfer of the symlink and the transfer of the referent directory as | |
13 | separate args. (See also --keep-dirlinks and --no-implied-dirs.) | |
2268defe | 14 | Also, exclude rules no longer have a partial effect on implied dirs. |
3f655768 WD |
15 | |
16 | - Requesting a remote file list without specifying -r (--recursive) now | |
17 | sends the -d (--dirs) option to the remote rsync rather than sending -r | |
18 | along with an extra exclude of /*/*. If the remote rsync does not | |
19 | understand the -d option (i.e. it is 2.6.3 or older), you will need to | |
44a7ba45 | 20 | either turn off -d (--no-d), or specify -r --exclude='/*/*' manually. |
4f3c1df6 | 21 | |
879b6ad0 WD |
22 | - In --dry-run mode, the last line of the verbose summary text is output |
23 | with a "(DRY RUN)" suffix to help remind you that no updates were made. | |
8340aa96 | 24 | Similarly, --only-write-batch outputs "(BATCH ONLY)". |
879b6ad0 | 25 | |
2268defe | 26 | - A writable rsync daemon with "use chroot" disabled now defaults to a |
932fcfc1 WD |
27 | symlink-munging behavior designed to make symlinks safer while also |
28 | allowing absolute symlinks to be stored and retrieved. This also has | |
29 | the effect of making symlinks unusable while they're in the daemon's | |
0b52f94d | 30 | hierarchy. See the daemon's "munge symlinks" parameter for details. |
932fcfc1 | 31 | |
ac1541f4 WD |
32 | BUG FIXES: |
33 | ||
293b11b8 WD |
34 | - A daemon with "use chroot = no" and excluded items listed in the daemon |
35 | config file now properly checks an absolute-path arg specified for these | |
36 | options: --compare-dest, --link-dest, --copy-dest, --partial-dir, | |
37 | --backup-dir, --temp-dir, and --files-from. | |
38 | ||
0b52f94d WD |
39 | - A daemon can now be told to disable all user- and group-name translation |
40 | on a per-module basis. This avoids a potential problem with a writable | |
41 | daemon module that has "use chroot" enabled -- if precautions weren't | |
42 | taken, a user could try to add a missing library and get rsync to use | |
43 | it. This makes rsync safer by default, and more configurable when id- | |
44 | translation is not desired. See the daemon's "numeric ids" parameter | |
45 | for full details. | |
46 | ||
f859d3de | 47 | - If a file's data arrived successfully on the receiving side but the |
2268defe WD |
48 | rename of the temporary file to the destination file failed AND the |
49 | --remove-source-files (or the deprecated --remove-sent-files) option | |
f859d3de WD |
50 | was specified, rsync no longer erroneously removes the associated |
51 | source file. | |
52 | ||
3a72cc29 WD |
53 | - Fixed the output of -ii when combined with one of the --*-dest options: |
54 | it now itemizes all the items, not just the changed ones. | |
55 | ||
56 | - Made the output of all file types consistent when using a --*-dest | |
2f39f112 | 57 | option. Prior versions would output too many creation events for |
3a72cc29 | 58 | matching items. |
b4f02871 | 59 | |
9439c0cb WD |
60 | - The code that waits for a child pid now handles being interrupted by a |
61 | signal. This fixes a problem with the pre-xfer exec function not being | |
62 | able to get the exit status from the script. | |
3481bdf4 | 63 | |
2f39f112 WD |
64 | - A negated filter rule (i.e. with a '!' modifier) no longer loses the |
65 | negation when sending the filter rules to the remote rsync. | |
d0d0e41f | 66 | |
4f3c1df6 | 67 | - Fixed a problem with the --out-format (aka --log-format) option %f: it |
2f39f112 | 68 | no longer outputs superfluous directory info for a non-daemon rsync. |
889ae39d | 69 | |
8b584075 WD |
70 | - Fixed a problem with -vv (double --verbose) and --stats when "pushing" |
71 | files (which includes local copies). Version 2.6.9 would complete the | |
72 | copy, but exit with an error when the receiver output its memory stats. | |
73 | ||
99effefc WD |
74 | - If --password-file is used on a non-daemon transfer, rsync now complains |
75 | and exits. This should help users figure out that they can't use this | |
76 | option to control a remote shell's password prompt. | |
e8dad395 | 77 | |
d762dfe9 WD |
78 | - Make sure that directory permissions of a newly-created destination |
79 | directory are handled right when --perms is left off. | |
80 | ||
4f3c1df6 WD |
81 | - The itemized output of a newly-created destination directory is now |
82 | output as a creation event, not a change event. | |
83 | ||
9c528e29 WD |
84 | - Improved --hard-link so that more corner cases are handled correctly |
85 | when combined with options such as --link-dest and/or --ignore-existing. | |
86 | ||
4f3c1df6 WD |
87 | - The --append option no longer updates a file that has the same size. |
88 | ||
89 | - Fixed a bug when combining --backup and --backup-dir with --inplace: | |
90 | any missing backup directories are now created. | |
91 | ||
92 | - Fixed a bug when using --backup and --inplace with --whole-file or | |
93 | --read-batch: backup files are actually created now. | |
94 | ||
0438c59f WD |
95 | - Starting up an extra copy of an rsync daemon will not clobber the pidfile |
96 | for the running daemon -- if the pidfile exists, the new daemon will exit | |
97 | with an error. | |
0f8984ed WD |
98 | |
99 | - The daemon pidfile is checked and created sooner in the startup sequence. | |
100 | ||
d46b5646 WD |
101 | - If a daemon module's "path" value is not an absolute pathname, the code |
102 | now makes it absolute internally (making it work properly). | |
103 | ||
f153c9c9 WD |
104 | - Ensure that a temporary file always has owner-write permission while we |
105 | are writing to it. This avoids problems with some network filesystems. | |
106 | ||
107 | - Any errors output about password-file reading no longer cause an error at | |
108 | the end of the run about a partial transfer. | |
109 | ||
da01d2e8 WD |
110 | - The --read-batch option for protocol 30 now ensures that several more |
111 | options are set correctly for the current batch file: --iconv, --acls, | |
112 | --xattrs, --inplace, --append, and --append-verify. | |
113 | ||
932fcfc1 WD |
114 | - Using --only-write-batch to a daemon receiver now work properly (older |
115 | versions would update some files while writing the batch). | |
116 | ||
0b52f94d | 117 | - Avoid outputting a "file has vanished" message when the file is a broken |
8340aa96 WD |
118 | symlink and --copy-unsafe-links or --copy-dirlinks are used (the code |
119 | already handled this for --copy-links). | |
120 | ||
c9d3bc3f WD |
121 | - Fixed the combination of --only-write-batch and --dry-run. |
122 | ||
ac1541f4 WD |
123 | ENHANCEMENTS: |
124 | ||
012d1a01 | 125 | - A new incremental-recursion algorithm is now used when rsync is talking |
4f3c1df6 | 126 | to another 3.x version. This starts the transfer going more quickly |
012d1a01 WD |
127 | (before all the files have been found), and requires much less memory. |
128 | See the --recursive option in the manpage for some restrictions. | |
129 | ||
d46b5646 | 130 | - Lowered memory use in the non-incremental-recursion algorithm for typical |
4f3c1df6 WD |
131 | option values (usually saving from 21-29 bytes per file). |
132 | ||
012d1a01 WD |
133 | - The default --delete algorithm is now --delete-during when talking to a |
134 | 3.x rsync. This is a faster scan than using --delete-before (which is | |
9439c0cb WD |
135 | the default when talking to older rsync versions), and is compatible with |
136 | the new incremental recursion mode. | |
012d1a01 | 137 | |
f89617f7 WD |
138 | - Rsync now allows multiple remote-source args to be specified rather than |
139 | having to rely on a special space-splitting side-effect of the remote- | |
2f39f112 WD |
140 | shell. Additional remote args must specify the same host or an empty one |
141 | (e.g. empty: :file1 or ::module/file2). This means that local use of | |
142 | brace expansion now works: rsync -av host:dir/{f1,f2} . | |
f89617f7 | 143 | |
d46b5646 WD |
144 | - Added the --protect-args (-s) option, that tells rsync to send most of |
145 | the command-line args at the start of the transfer rather than as args | |
146 | to the remote-shell command. This protects them from space-splitting, | |
147 | and only interprets basic wildcard special shell characters (*?[). | |
148 | ||
9439c0cb WD |
149 | - Added the --delete-delay option, which is a more efficient way to delete |
150 | files at the end of the transfer without needing a separate delete pass. | |
c7871d98 | 151 | |
348d54d6 | 152 | - Added the --acls (-A) option to preserve Access Control Lists. This is |
4f3c1df6 | 153 | an improved version of the prior patch that was available, and it even |
97bcf138 | 154 | supports OS X ACLs. If you need to have backward compatibility with old, |
2268defe | 155 | ACL-patched versions of rsync, apply the acls.diff file from the patches |
97bcf138 | 156 | dir. |
348d54d6 WD |
157 | |
158 | - Added the --xattrs (-X) option to preserver extended attributes. This is | |
97bcf138 WD |
159 | an improved version of the prior patch that was available, and it even |
160 | supports OS X xattrs (which includes their resource fork data). If you | |
161 | need to have backward compatibility with old, xattr-patched versions of | |
162 | rsync, apply the xattrs.diff file from the patches dir. | |
348d54d6 | 163 | |
9439c0cb WD |
164 | - Added the --fake-super option that allows a non-super user to preserve |
165 | all attributes of a file by using a special extended-attribute idiom. | |
97bcf138 | 166 | It even supports the storing of foreign ACL data on your backup server. |
0b52f94d | 167 | There is also an analogous "fake super" parameter for an rsync daemon. |
9439c0cb | 168 | |
332cf6df | 169 | - Added the --iconv option, which allows rsync to convert filenames from |
0156c784 WD |
170 | one character-set to another during the transfer. The default is to make |
171 | this feature available as long as your system has iconv_open(). If | |
4f3c1df6 WD |
172 | compilation fails, specify --disable-iconv to configure, and then |
173 | rebuild. If you want rsync to perform character-set conversions by | |
174 | default, you can specify --enable-iconv=CONVERT_STRING with the default | |
175 | value for the --iconv option that you wish to use. For example, | |
d46b5646 | 176 | "--enable-iconv=." is a good choice. See the rsync manpage for an |
4f3c1df6 | 177 | explanation of the --iconv option's settings. |
332cf6df | 178 | |
0b52f94d WD |
179 | - A new daemon config parameter, "charset", lets you control the character- |
180 | set that is used during an --iconv transfer to/from a daemon module. | |
181 | ||
d46b5646 | 182 | - Added the --skip-compress=LIST option to override the default list of |
9c528e29 | 183 | file suffixes that will not be compressed when using --compress. |
c9d3bc3f | 184 | |
4f3c1df6 WD |
185 | - The daemon's default for "dont compress" was extended to include: |
186 | *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg | |
187 | The matching routine was also optimized to run more quickly. | |
9c528e29 | 188 | |
836ce36a WD |
189 | - The --max-delete option now outputs a warning if it skipped any file |
190 | deletions, including a count of how many deletions were skipped. (Older | |
191 | versions just silently stopped deleting things.) | |
192 | ||
193 | - You may specify --max-delete=0 to a 3.0.0 client to request that it warn | |
4f3c1df6 WD |
194 | about extraneous files without deleting anything. If you're not sure |
195 | what version the client is, you can use the less-obvious --max-delete=-1, | |
196 | as both old and new versions will treat that as the same request (though | |
197 | older versions don't warn). | |
8adc22e3 | 198 | |
3a5a7de6 | 199 | - The --hard-link option now uses less memory on both the sending and |
9439c0cb WD |
200 | receiving side for all protocol versions. For protocol 30, the use of a |
201 | hashtable on the sending side allows us to more efficiently convey to the | |
202 | receiver what files are linked together. This reduces the amount of data | |
203 | sent over the socket by a considerable margin (rather than adding more | |
204 | data), and limits the in-memory storage of the device+inode information | |
205 | to just the sending side for the new protocol 30, or to the receiving | |
206 | side when speaking an older protocol (note that older rsync versions kept | |
207 | the device+inode information on both sides). | |
3a5a7de6 | 208 | |
4f3c1df6 WD |
209 | - The filter rules now support a perishable ("p") modifier that marks rules |
210 | that should not have an effect in a directory that is being deleted. e.g. | |
211 | -f '-p .svn/' would only affect "live" .svn directories. | |
212 | ||
293b11b8 WD |
213 | - Rsync checks all the alternate-destination args for validity (e.g. |
214 | --link-dest). This lets the user know when they specified a directory | |
215 | that does not exist. | |
216 | ||
4f3c1df6 WD |
217 | - If we get an error setting the time on a symlink, we don't complain about |
218 | it anymore (since some operating systems don't support that, and it's not | |
219 | that important). | |
220 | ||
4f3c1df6 WD |
221 | - Protocol 30 now uses MD5 checksums instead of MD4. |
222 | ||
4f3c1df6 WD |
223 | - Changed the --append option to not checksum the existing data in the |
224 | destination file, which speeds up file appending. | |
225 | ||
226 | - Added the --append-verify option, which works like the older --append | |
227 | option (verifying the existing data in the destination file). For | |
228 | compatibility with older rsync versions, any use of --append that is | |
229 | talking protocol 29 or older will revert to the --append-verify method. | |
230 | ||
932fcfc1 WD |
231 | - Added the --contimeout=SECONDS option that lets the user specify a |
232 | connection timeout for rsync daemon access. | |
233 | ||
4f3c1df6 | 234 | - Documented and extended the support for the RSYNC_CONNECT_PROG variable |
0f8984ed | 235 | that can be used to enhance the client side of a daemon connection. |
4f3c1df6 | 236 | |
0f8984ed WD |
237 | - Improved the dashes and double-quotes in the nroff manpage output. |
238 | ||
239 | - We now support a lot more --no-OPTION override options. | |
240 | ||
4968423e WD |
241 | INTERNAL: |
242 | ||
0e5dd898 WD |
243 | - The file-list sorting algorithm now uses a sort that keeps any same- |
244 | named items in the same order as they were specified. This allows | |
245 | rsync to always ensure that the first of the duplicates is the one | |
f45b64d8 WD |
246 | that will be included in the copy. The new sort was also faster |
247 | than the glibc version of qsort() and mergesort() in my testing. | |
0e5dd898 | 248 | |
348d54d6 WD |
249 | - Rsync now supports the transfer of 64-bit timestamps (time_t values). |
250 | ||
c9d3bc3f WD |
251 | - Made the file-deletion code use a little less stack when recursing |
252 | through a directory hierarchy of extraneous files. | |
253 | ||
348d54d6 WD |
254 | - Fixed a build problem with older (2.x) versions of gcc. |
255 | ||
4d2ea5a8 WD |
256 | - Added some isType() functions that make dealing with signed characters |
257 | easier without forcing variables via casts. | |
258 | ||
4f3c1df6 WD |
259 | - Changed strcat/strcpy/sprintf function calls to use safer versions. |
260 | ||
3a72cc29 WD |
261 | - Upgraded the included popt version to 1.10.2 and improved its use of |
262 | string-handling functions. | |
418da6d9 | 263 | |
d0d0e41f WD |
264 | - Added missing prototypes for compatibility functions from the lib dir. |
265 | ||
c7871d98 WD |
266 | - Configure determines if iconv() has a const arg, allowing us to avoid a |
267 | compiler warning. | |
268 | ||
269 | - Made the sending of some numbers more efficient for protocol 30. | |
d0d0e41f | 270 | |
d762dfe9 WD |
271 | - Make sure that a daemon process doesn't mind if the client was weird and |
272 | omitted the --server option. | |
273 | ||
932fcfc1 WD |
274 | - There are more internal logging categories available in protocol 30 than |
275 | the age-old FINFO and FERROR, including FERROR_XFER and FWARN. These new | |
276 | categories allow some errors and warnings to go to stderr without causing | |
277 | an erroneous end-of-run warning about some files not being able to be | |
278 | transferred. | |
279 | ||
d0d0e41f WD |
280 | - Improved the use of "const" on pointers. |
281 | ||
1c4ffe64 WD |
282 | - Improved J.W.'s pool_alloc routines to add a way of freeing older |
283 | sections of a pool's memory. | |
284 | ||
f153c9c9 WD |
285 | - The getaddrinfo.c compatibility code in the "lib" dir was replaced with |
286 | some new code (derived from samba, derived from PostgreSQL) that has a | |
287 | better license than the old code. | |
288 | ||
7c329ec7 WD |
289 | DEVELOPER RELATED: |
290 | ||
8798be8e WD |
291 | - Rsync is now licensed under the GPLv3 or later. |
292 | ||
932fcfc1 WD |
293 | - Rsync is now being maintained in a "git" repository instead of CVS |
294 | (though the old CVS repository still exists). Several maintenance | |
295 | scripts were updated to work with git. | |
296 | ||
297 | - Generated files are no longer committed into the source repository. The | |
298 | autoconf and autoheader commands are now automatically run during the | |
299 | normal use of "configure" and "make". The latest dev versions of all | |
300 | generated files can also be copied from the samba.org web site (see the | |
301 | "magic" configure script that now comes with rsync for its location). | |
302 | ||
303 | - The "patches" directory of diff files is now built from branches in the | |
304 | rsync git repository (branch patch/FOO creates file patches/FOO.diff). | |
305 | ||
306 | - The proto.h file is now built using a simple perl script rather than a | |
307 | complex awk script, which proved to be more widely compatible. | |
308 | ||
4f3c1df6 WD |
309 | - When running the tests, we now put our per-test temp dirs into a sub- |
310 | directory named testtmp (which is created, if missing). This allows | |
311 | someone to symlink the testtmp directory to another filesystem (which is | |
312 | useful if the build dir's filesystem does not support ACLs and xattrs, | |
2f39f112 | 313 | but another file system does). |
4f3c1df6 | 314 | |
348d54d6 | 315 | - Rsync now has a way of handling protocol-version changes during the |
d46b5646 WD |
316 | development of a new protocol version. This causes any out-of-sync |
317 | versions to speak an older protocol rather than fail in a cryptic manner. | |
318 | This addition makes it safe to deploy a pre-release version that may | |
319 | interact with the public. This new exchange of sub-version info does not | |
320 | interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which | |
321 | does not have enough range to allow the main protocol number to be | |
322 | incremented for every minor tweak in that happens during development). | |
932fcfc1 WD |
323 | |
324 | - The csprotocol.txt file was updated to mention the daemon protocol change | |
325 | in the 3.0.0 release. |
