1 | NEWS for rsync 2.6.7 (11 Mar 2006) |
2 | ||
3ae6c187 | 3 | Protocol: 29 (unchanged) |
f90f7149 | 4 | Changes since 2.6.6: |
9db17434 | 5 | |
d671ccfc WD |
6 | OUTPUT CHANGES: |
7 | ||
1e2b96bb WD |
8 | - The letter 'D' in the itemized output was being used for both devices |
9 | (character or block) as well as other special files (such as fifos and | |
10 | named sockets). This has changed to separate non-device special files | |
11 | under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the | |
12 | "--specials" option, below. | |
d671ccfc | 13 | |
36f59b58 WD |
14 | - The way rsync escapes unreadable characters has changed. First, rsync |
15 | now has support for recognizing valid multibyte character sequences in | |
16 | your current locale, allowing it to escape fewer characters than before | |
17 | for a locale such as UTF-8. Second, it now uses an escape idiom of | |
18 | "\#123", which is the literal string "\#" followed by exactly 3 octal | |
19 | digits. Rsync no longer doubles a backslash character in a filename | |
20 | (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only | |
21 | escapes a backslash that is followed by a hash-sign and 3 digits (0-9) | |
45b79c89 | 22 | (e.g. it will output "foo\#134#789" when copying "foo\#789"). See also |
a6a27602 | 23 | the --8-bit-output (-8) option, mentioned below. |
36f59b58 WD |
24 | |
25 | Script writers: the local rsync is the one that outputs escaped names, | |
26 | so if you need to support unescaping of filenames for older rsyncs, I'd | |
27 | suggest that you parse the output of "rsync --version" and only use the | |
28 | old unescaping rules for 2.6.5 and 2.6.6. | |

30 | BUG FIXES: |
31 | ||
23740239 | 32 | - Fixed a really old bug that caused --checksum (-c) to checksum all the |
da2d13e3 | 33 | files encountered during the delete scan (ouch). |
23740239 | 34 | |
2fb450bd WD |
35 | - Fixed a potential hang in a remote generator: when the receiver gets a |
36 | read-error on the socket, it now signals the generator about this so that | |
37 | the generator does not try to send any of the terminating error messages | |
38 | to the client (avoiding a potential hang in some setups). | |
39 | ||
56961bec WD |
40 | - Made hard-links work with symlinks and devices again. |
41 | ||
5481e42c WD |
42 | - If the sender gets an early EOF reading a source file, we propagate this |
43 | error to the receiver so that it can discard the file and try requesting | |
44 | it again (which is the existing behavior for other kinds of read errors). | |
45 | ||
fbe57fdc WD |
46 | - If a device-file/special-file changes permissions, rsync now updates the |
47 | permissions without recreating the file. | |
4fdb03a6 | 48 | |
9425918d WD |
49 | - If the user specifies a remote-host for both the source and destination, |
50 | we now output a syntax error rather than trying to open the destination | |
51 | hostspec as a filename. | |
52 | ||
7ea7bebf WD |
53 | - When --inplace creates a new destination file, rsync now creates it with |
54 | permissions 0600 instead of 0000 -- this makes restarting possible when | |
55 | the transfer gets interrupted in the middle of sending a new file. | |
56 | ||
ec69bdbd WD |
57 | - Reject the combination of --inplace and --sparse since the sparse-output |
58 | algorithm doesn't work when overwriting existing data. | |
59 | ||
fbe57fdc WD |
60 | - Fixed the directory name in the error that is output when pop_dir() |
61 | fails. | |
62 | ||
02efda9f WD |
63 | - Really fixed the parsing of a "!" entry in .cvsignore files this time. |
64 | ||
ce0da32a WD |
65 | - If the generator gets a stat() error on a file, output it (this used to |
66 | require at least -vv for the error to be seen). | |
67 | ||
68 | - If waitpid() fails or the child rsync didn't exit cleanly, we now handle | |
69 | the exit status properly and generate a better error. | |
0417c34e | 70 | |
8a1f3153 | 71 | - Fixed some glitches in the double-verbose output when using --copy-dest, |
567f1566 WD |
72 | --link-dest, or --compare-dest. Also improved how the verbose output |
73 | handles hard-links (within the transfer) that had an up-to-date alternate | |
74 | "dest" file, and copied files (via --copy-dest). | |
8a1f3153 | 75 | |
515afe7c WD |
76 | - Fixed the matching of the dont-compress items (e.g. *.gz) against files |
77 | that have a path component containing a slash. | |
78 | ||
d37bc73a WD |
79 | - If code reading a filter/exclude file an EINTR error, rsync now clears |
80 | the error flag on the file handle so it can keep on reading. | |
81 | ||
87001ac6 WD |
82 | - If --relative is active, the sending side cleans up trailing "/" or "/." |
83 | suffixes to avoid triggering a bug in older rsync versions. Also, we now | |
84 | reject a ".." dir if it would be sent as a relative dir. | |
d37bc73a | 85 | |
2a59d2cc | 86 | - If a non-directory is in the way of a directory and rsync is run with |
5481e42c WD |
87 | --dry-run and --delete, rsync no longer complains about not being able |
88 | to opendir() the not-yet present directory. | |
2a59d2cc | 89 | |
1e44aeb9 WD |
90 | - When --list-only is used and a non-existent local destination dir was |
91 | also specified as a destination, rsync no longer generates a warning | |
92 | about being unable to create the missing directory. | |
93 | ||
06982ac4 WD |
94 | - Fixed some problems with --relative --no-implied-dirs when the |
95 | destination directory did not yet exist: we can now create a symlink or | |
96 | device when it is the first thing in the missing dir, and --fuzzy no | |
97 | longer complains about being unable to open the missing dir. | |
98 | ||
07affc3d | 99 | - Fixed a bug where the --copy-links option would not affect implied |
16d3b31b | 100 | directories without --copy-unsafe-links (see --relative). |
07affc3d | 101 | |
63344ad4 WD |
102 | - Got rid of the need for --force to be used in some circumstances with |
103 | --delete-after (making it consistent with --delete-before/-during). | |
104 | ||
71a84cba WD |
105 | - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this |
106 | when a file is too large (rsync handles the write error). | |
107 | ||
1c598b1d WD |
108 | - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it |
109 | was not properly padded with trailing '=' chars. This only affects a | |
110 | user that need to use a password-authenticated proxy for an outgoing | |
111 | daemon-rsync connection. | |
112 | ||
1ef79134 WD |
113 | - If we're transferring an empty directory to a new name, rsync no longer |
114 | forces S_IWUSR if it wasn't already set, nor does it accidentally leave | |
115 | it set. | |
116 | ||
89a8180c WD |
117 | - Fixed a bug in the debug output (-vvvvv) that could mention the wrong |
118 | checksum for the current file offset. | |
119 | ||
b5cf121d WD |
120 | - Rsync no longer allows a single directory to be copied over a non- |
121 | directory destination arg. | |
122 | ||
ac1541f4 WD |
123 | ENHANCEMENTS: |
124 | ||
5481e42c WD |
125 | - Added the --append option that makes rsync append data onto files that |
126 | are longer on the source than the destination (this includes new files). | |
870dddc5 | 127 | |
bad01106 WD |
128 | - Added the --min-size=SIZE option to exclude small files from the |
129 | transfer. | |
130 | ||
131 | - Added the --compress-level option to allow you to set how aggressive | |
da2d13e3 | 132 | rsync's compression should be (this option implies --compress). |
d697314b | 133 | |
5481e42c WD |
134 | - Enhanced the parsing of the SIZE value for --min-size and --max-size to |
135 | allow easy entry of multiples of 1000 (instead of just multiples of 1024) | |
136 | and off-by-one values too (e.g. --max-size=8mb-1). | |
889439c2 | 137 | |
a6a27602 WD |
138 | - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping |
139 | high-bit characters that it thinks are unreadable in the current locale. | |
45b79c89 | 140 | |
f65e6a12 WD |
141 | - The new option --human-readable (-h) changes the output of --progress, |
142 | --stats, and the end-of-run summary to be easier to read. If repeated, | |
1e2b96bb WD |
143 | the units become powers of 1024 instead of powers of 1000. (The old |
144 | meaning of -h, as a shorthand for --help, still works as long as you | |
145 | just use it on its own, as in "rsync -h".) | |
d697314b | 146 | |
f90f7149 WD |
147 | - If lutimes() and/or lchmod() are around, use them to allow the |
148 | preservation of attributes on symlinks. | |
7d7a34ae | 149 | |
5481e42c | 150 | - The --link-dest option now affects symlinks and devices (when possible). |
8a1f3153 | 151 | |
5481e42c WD |
152 | - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" and |
153 | "post-xfer exec". These allow a command to be specified on a per-module | |
154 | basis that will be run before and/or after a daemon-mode transfer. (See | |
567f1566 | 155 | the man page for a list of the environment variables that are set with |
5481e42c | 156 | information about the transfer.) |
5b9cc695 | 157 | |
56961bec WD |
158 | - When using the --relative option, you can now insert a dot dir in |
159 | the source path to indicate where the replication of the source dirs | |
160 | should start. For example, if you specify a source path of | |
da2d13e3 | 161 | rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only |
56961bec WD |
162 | replicate the "baz/dir" part of the source path (note: a trailing |
163 | dot dir is unaffected unless it also has a trailing slash). | |
164 | ||
5481e42c WD |
165 | - Added some new --no-FOO options that make it easier to override unwanted |
166 | implied or default options. For example, "-a --no-o" (aka "--archive | |
167 | --no-owner") can be used to turn off the preservation of file ownership | |
168 | that is implied by -a. | |
a912a980 | 169 | |
5481e42c WD |
170 | - Added the --chmod=MODE option that allows the destination permissions to |
171 | be changed from the source permissions. E.g. --chmod=g+w,o-rwx | |
ef3bb69a | 172 | |
50fd4832 WD |
173 | - Added the "incoming chmod" and "outgoing chmod" daemon options that allow |
174 | a module to specify what permissions changes should be applied to all | |
175 | files copied to and from the daemon. | |
63344ad4 | 176 | |
5481e42c WD |
177 | - Allow the --temp-dir option to be specified when starting a daemon, which |
178 | sets the default temporary directory for incoming files. | |
ec69bdbd | 179 | |
5481e42c WD |
180 | - If --delete is combined with --dirs without --recursive, rsync will now |
181 | delete in any directory whose content is being synchronized. | |
ce0da32a | 182 | |
5481e42c WD |
183 | - If --backup is combined with --delete without --backup-dir (and without |
184 | --delete-excluded), we add a "protect" filter-rule to ensure that files | |
185 | with the backup suffix are not deleted. | |
2067ec73 | 186 | |
3b153409 WD |
187 | - The file-count stats that are output by --progress were improved to |
188 | better indicate what the numbers mean. For instance, the output: | |
0ee32c62 WD |
189 | "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file |
190 | to be transferred, and we still need to check 8383 more files out of | |
191 | a total of 9999. | |
3b153409 | 192 | |
5481e42c WD |
193 | - The include/exclude code now allows a dir/*** directive (with 3 trailing |
194 | stars) to match both the dir itself as well as all the content below the | |
195 | dir (dir/** would not match the dir). | |
d37bc73a | 196 | |
5481e42c WD |
197 | - Added the --prune-empty-dirs (-m) option that makes the receiving rsync |
198 | discard empty chains of directories from the file-list. This makes it | |
199 | easier to selectively copy files from a source hierarchy and end up with | |
200 | just the directories needed to hold the resulting files. | |
a324d49b | 201 | |
458aeea4 | 202 | - If the --itemize-changes (-i) option is repeated, rsync now includes |
5481e42c WD |
203 | unchanged files in the itemized output (similar to -vv, but without all |
204 | the other verbose messages that can get in the way). Of course, the | |
205 | client must be version 2.6.7 for this to work, but the remote rsync only | |
206 | needs to be 2.6.7 if you're pushing files. | |
458aeea4 | 207 | |
1e2b96bb WD |
208 | - Added the --specials option to tell rsync to copy non-device special |
209 | files (which rsync now attempts even as a normal user). The --devices | |
210 | option now requests the copying of just devices (character and block). | |
211 | The -D option still requests both (e.g. --devices and --specials), -a | |
212 | still implies -D, and non-root users still get a silent downgrade that | |
213 | omits device copying. | |
214 | ||
215 | - Added the --super option to make the receiver always attempt super-user | |
5481e42c WD |
216 | activities. This is useful for systems that allow things such as devices |
217 | to be created or ownership to be set without being UID 0, and is also | |
218 | useful for someone who wants to ensure that errors will be output if the | |
219 | receiving rsync isn't being run as root. | |
f5b14759 | 220 | |
5481e42c WD |
221 | - Added the --sockopts option for those few who want to customize the TCP |
222 | options used to contact a daemon rsync. | |
f7916cbf | 223 | |
63344ad4 WD |
224 | - Added a way for the --temp-dir option to be combined with a partial-dir |
225 | setting that lets rsync avoid non-atomic updates (for those times when | |
226 | --temp-dir is not being used because space is tight). | |
227 | ||
2959fe74 WD |
228 | - A new support script, files-to-excludes, will transform a list of files |
229 | into a set of include/exclude directives that will copy those files. | |
230 | ||
231 | - A new option, --executability (-E) can be used to preserve just the | |
232 | execute bit on files, for those times when using the --perms option is | |
233 | not desired. | |
234 | ||
65535b54 WD |
235 | - The daemon now logs each connection and also each module-list request |
236 | that it receives. | |
49f4d850 WD |
237 | |
238 | - New log-format options: %M (modtime), %U (uid), %G (gid), and %B | |
239 | (permission bits, e.g. "rwxr-xrwt"). | |
240 | ||
20a02697 WD |
241 | - The --dry-run option no longer forces the enabling of --verbose. |
242 | ||
42003f6a WD |
243 | - The --remove-sent-files option now does a better job of incrementally |
244 | removing the sent files on the sending side (older versions tended to | |
245 | clump up all the removals at the end). | |
246 | ||
81f654e3 | 247 | - A daemon now supersedes its minimal SIGCHLD handler with the standard |
16d3b31b WD |
248 | PID-remembering version after forking. This ensures that the generator |
249 | can get the child-exit status from the receiver. | |
81f654e3 WD |
250 | |
251 | - Use of the --bwlimit option no longer interferes with the remote rsync | |
252 | sending error messages about invalid/refused options. | |
253 | ||
1e44aeb9 WD |
254 | - Rsync no longer returns a usage error when used with one local source arg |
255 | and no destination: this now implies the --list-only option, just like | |
256 | the comparable situation with a remote source arg. | |
257 | ||
07affc3d WD |
258 | - Added the --copy-dirlinks option, a more limited version of --copy-links. |
259 | ||
567f1566 WD |
260 | - Various documentation improvements, including: a better synopsis, some |
261 | improved examples, a better discussion of the presence and absence of | |
262 | --perms (including how it interacts with the new --executability and | |
263 | --chmod options), an extended discussion of --temp-dir, an improved | |
264 | discussion of --partial-dir, a better description of rsync's pattern | |
07affc3d WD |
265 | matching characters, an improved --no-implied-dirs section, and the |
266 | documenting of what the --stats option outputs. | |
e3f83953 | 267 | |
567f1566 WD |
268 | - Various new and updated diffs in the patches dir, including: acls.diff, |
269 | xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff. | |
0417c34e | 270 | |
5b9cc695 WD |
271 | INTERNAL: |
272 | ||
5cf48960 WD |
273 | - We now use sigaction() and sigprocmask() if possible, and fall back on |
274 | signal() if not. Using sigprocmask() ensures that rsync enables all the | |
275 | signals that it needs, just in case it was started in a masked state. | |
276 | ||
5b9cc695 WD |
277 | - Some buffer sizes were expanded a bit, particularly on systems where |
278 | MAXPATHLEN is overly small (e.g. cygwin). | |
279 | ||
280 | - If io_printf() tries to format more data than fits in the buffer, exit | |
281 | with an error instead of transmitting a truncated buffer. | |
ce0da32a | 282 | |
d409c6ac WD |
283 | - If a va_copy macro is defined, lib/snprintf.c will use it when defining |
284 | the VA_COPY macro. | |
285 | ||
b1b04fcd WD |
286 | - Reduced the amount of stack memory needed for each level of directory |
287 | recursion by nearly MAXPATHLEN bytes. | |
288 | ||
5481e42c WD |
289 | - The wildmatch function was extended to allow an array of strings to be |
290 | supplied as the string to match. This allows the exclude code to do less | |
291 | string copying. | |
d37bc73a WD |
292 | |
293 | - Got rid of the safe_fname() function (and all the myriad calls) and | |
5481e42c WD |
294 | replaced it with a new function in the log.c code that filters all the |
295 | output going to the terminal. | |
d37bc73a WD |
296 | |
297 | - Unified the f_name() and the f_name_to() functions. | |
298 | ||
2384f9e1 WD |
299 | - Improved the hash-table code the sender uses to handle checksums to make |
300 | it use slightly less memory and run just a little faster. | |
301 | ||
ce0da32a WD |
302 | DEVELOPER RELATED: |
303 | ||
4e194bf1 WD |
304 | - The diffs in the patches dir now require "patch -p1 <DIFF" instead of |
305 | the previous -p0. Also, the version included in the release tar now | |
306 | affect generated files (e.g. configure, rsync.1, proto.h, etc.), so | |
307 | it is no longer necessary to run autoconf and/or yodl unless you're | |
308 | applying a patch that was checked out from CVS. | |
309 | ||
ce0da32a WD |
310 | - Several diffs in the patches dir now use the proper --enable-FOO |
311 | configure option instead of --with-FOO to turn on the inclusion of | |
312 | the newly patched feature. | |
313 | ||
4e194bf1 WD |
314 | - There is a new script, "prepare-source" than can be used to update the |
315 | various generated files (proto.h, configure, etc.) even before configure | |
316 | has created the Makefile (this is mainly useful when patching the source | |
317 | with a patch that doesn't affect generated files). | |
318 | ||
319 | - The testsuite now sets HOME so that it won't be affected by a file such | |
320 | as ~/.popt. |
