1 | NEWS for rsync 2.6.4 (UNRELEASED) |
2 | Protocol: 28 (unchanged) | |
3 | Changes since 2.6.3: | |
4 | ||
5 | BUG FIXES: | |
6 | ||
7 | - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3 | |
8 | was only treating it as a special token in an rsync include/exclude | |
9 | file). | |
10 | ||
11 | - An OS that has a binary mode for its files (such as cygwin0 needed | |
12 | setmode(fd, O_BINARY) called on the temp-file we opened with | |
13 | mkstemp(). | |
14 | ||
15 | - We now check if the OS doesn't support using mknod() for creating | |
16 | FIFOs and sockets, and compile-in using mkfifo() and socket() when | |
17 | necessary. | |
18 | ||
740bab94 WD |
19 | - Fixed an off-by-one error in the handling of --max-delete=N. |
20 | ||
ac1541f4 WD |
21 | ENHANCEMENTS: |
22 | ||
18ea5dc0 WD |
23 | - The daemon-mode options were separated from the normal rsync options |
24 | so that they can't be mixed together. This makes it impossible for a | |
25 | user to start a daemon that had improper default option values that | |
26 | could cause problems (a hang or an exit) when a client connects. | |
27 | ||
ac1541f4 WD |
28 | - In _exit_cleanup(): when we are exiting with a partially-received |
29 | file, we now flush any data in the write-cache before closing the | |
30 | partial file. | |
31 | ||
32 | BUILD CHANGES: | |
33 | ||
34 | - Support an OS that uses mkdev() instead of makedev(). | |

38 | Protocol: 28 (unchanged) |
39 | Changes since 2.6.2: | |
40 | ||
8fb7db24 WD |
41 | SECURITY FIXES: |
42 | ||
43 | - A bug in the sanitize_path routine (which affects a non-chrooted | |
d414962a WD |
44 | rsync daemon) could allow a user to craft a pathname that would get |
45 | transformed into an absolute path for certain options (but not for | |
919ca3a3 | 46 | file-transfer names). If you're running an rsync daemon with chroot |
d414962a WD |
47 | disabled, *please upgrade*, ESPECIALLY if the user privs you run |
48 | rsync under is anything above "nobody". | |
8fb7db24 | 49 | |
f6c0d3d7 WD |
50 | OUTPUT CHANGES (ATTN: those using a script to parse the verbose output): |
51 | ||
52 | - Please note that the 2-line footer (output when verbose) now uses the | |
53 | term "sent" instead of "wrote" and "received" instead of "read". If | |
54 | you are not parsing the numeric values out of this footer, a script | |
82c6be7e | 55 | would be better off using the empty line prior to the footer as the |
f6c0d3d7 | 56 | indicator that the verbose output is over. |
446a2987 | 57 | |
f6c0d3d7 WD |
58 | - The output from the --stats option was similarly affected to change |
59 | "written" to "sent" and "read" to "received". | |
60 | ||
82c6be7e WD |
61 | - Rsync ensures that a filename that contains a newline gets mentioned |
62 | with each newline transformed into a question mark (which prevents a | |
63 | filename from causing an empty line to be output). | |
446a2987 | 64 | |
a3571c6c WD |
65 | - The "backed up ..." message that is output when at least 2 --verbose |
66 | options are specified is now the same both with and without the | |
67 | --backup-dir option. | |
68 | ||
03a9ca0a WD |
69 | BUG FIXES: |
70 | ||
831f05df WD |
71 | - Fixed a crash bug that might appear when --delete was used and |
72 | multiple source directories were specified. | |
03a9ca0a | 73 | |
6c3fda83 | 74 | - Fixed a 32-bit truncation of the file length when generating the |
c7b1a56b WD |
75 | checksums. |
76 | ||
03a9ca0a WD |
77 | - The --backup code no longer attempts to create some directories |
78 | over and over again (generating warnings along the way). | |
79 | ||
cbd85b47 WD |
80 | - Fixed a bug in the reading of the secrets file (by the daemon) and |
81 | the password file (by the client): the files no longer need to be | |
82 | terminated by a newline for their content to be read in. | |
03a9ca0a | 83 | |
99d24f77 WD |
84 | - If a file has a read error on the sending side or the reconstructed |
85 | data doesn't match the expected checksum (perhaps due to the basis | |
86 | file changing during the transfer), the receiver will no longer | |
87 | retain the resulting file unless the --partial option was specified. | |
88 | (Note: for the read-error detection to work, neither side can be | |
89 | older than 2.6.3 -- older receivers will always retain the file, and | |
90 | older senders don't tell the receiver that the file had a read | |
91 | error.) | |
03a9ca0a | 92 | |
c54f5170 | 93 | - If a file gets resent in a single transfer and the --backup option |
82c6be7e WD |
94 | is enabled, rsync no longer performs a duplicate backup (it used to |
95 | overwrite the original file in the backup area). | |
03a9ca0a | 96 | |
cbd85b47 | 97 | - Files specified in the daemon's "exclude" or "exclude from" config |
bd1574b2 WD |
98 | items are now excluded from being uploaded (assuming that the module |
99 | allows uploading at all) in addition to the old download exclusion. | |
cbd85b47 | 100 | |
40e8d11e WD |
101 | - Got rid of a potential hang in the receiver when near the end of a |
102 | phase. | |
103 | ||
b03bded7 WD |
104 | - When using --backup without a --backup-dir, rsync no longer preserves |
105 | the modify time on directories. This avoids confusing NFS. | |
106 | ||
40e8d11e WD |
107 | - When --copy-links (-L) is specified, we now output a separate error |
108 | for a symlink that has no referent instead of claiming that a file | |
109 | "vanished". | |
110 | ||
f6c0d3d7 WD |
111 | - The --copy-links (-L) option no longer has the side-effect of telling |
112 | the receiving side to follow symlinks. See the --keep-dirlinks | |
113 | option (mentioned below) for a way to specify that behavior. | |
114 | ||
2c2898a3 | 115 | - Error messages from the daemon server's option-parsing (such as |
6c3fda83 WD |
116 | refused options) are now successfully transferred back to the client |
117 | (the server used to fail to send the message because the socket | |
118 | wasn't in the right state for the message to get through). | |
2c2898a3 | 119 | |
6c3fda83 WD |
120 | - Most transfer errors that occur during a daemon transfer are now |
121 | returned to the user in addition to being logged (some messages are | |
122 | intended to be daemon-only and are not affected by this). | |
c54f5170 | 123 | |
b03bded7 WD |
124 | - Fixed a bug in the daemon authentication code when using one of the |
125 | batch-processing options. | |
126 | ||
40564811 WD |
127 | - We try to work around some buggy IPv6 implementations that fail to |
128 | implement IPV6_V6ONLY. This should fix the "address in use" error | |
129 | that some daemons get when running on an OS with a buggy IPv6 | |
130 | implementation. Also, if the new code gets this error, we might | |
131 | suggest that the user specify --ipv4 or --ipv6 (if we think it will | |
132 | help). | |
133 | ||
65af3dab | 134 | - When the remote rsync dies, make a better effort to recover any error |
86e2f445 WD |
135 | messages it may have sent before dying (the local rsync used to just |
136 | die with a socket-write error). | |
65af3dab WD |
137 | |
138 | - When using --delete and a --backup-dir that contains files that are | |
139 | hard-linked to their destination equivalents, rsync now makes sure | |
6c3fda83 WD |
140 | that removed files really get removed (avoids a really weird rename() |
141 | behavior). | |
65af3dab WD |
142 | |
143 | - Avoid a bogus run-time complaint about a lack of 64-bit integers when | |
99d24f77 | 144 | the int64 type is defined as an off_t and it actually has 64-bits. |
65af3dab | 145 | |
00735149 WD |
146 | - Added a configure check for open64() without mkstemp64() so that we |
147 | can avoid using mkstemp() when such a combination is encountered. | |
148 | This bypasses a problem writing out large temp files on OSes such as | |
149 | AIX and HP-UX. | |
150 | ||
82c6be7e WD |
151 | - Fixed an age-old crash problem with --read-batch on a local copy |
152 | (rsync was improperly assuming --whole-file for the local copy). | |
153 | ||
154 | - When --dry-run (-n) is used and the destination directory does not | |
155 | exist, rsync now produces a correct report of files that would be | |
156 | sent instead of dying with a chdir() error. | |
157 | ||
37c36e26 WD |
158 | - Fixed a bug that could cause a slow-to-connect rsync daemon to die |
159 | with an error instead of waiting for the connection to finish. | |
160 | ||
a3571c6c WD |
161 | - Fixed an ssh interaction that could cause output to be lost when the |
162 | user chose to combine the output of rsync's stdout and stderr (e.g. | |
163 | using the "2>&1"). | |
164 | ||
03a9ca0a WD |
165 | ENHANCEMENTS: |
166 | ||
65af3dab WD |
167 | - Added the --partial-dir=DIR option that lets you specify where to |
168 | (temporarily) put a partially transferred file (instead of over- | |
169 | writing the destination file). E.g. --partial-dir=.rsync-partial | |
cc07f212 WD |
170 | Also added support for the RSYNC_PARTIAL_DIR environment variable |
171 | that, when found, transforms a regular --partial option (such as | |
172 | the convenient -P option) into one that also specifies a directory. | |
65af3dab | 173 | |
40e8d11e | 174 | - Added --keep-dirlinks (-K), which allows you to symlink a directory |
40564811 | 175 | onto another partition on the receiving side and have rsync treat it |
4e1f3857 WD |
176 | as matching a normal directory from the sender. |
177 | ||
61fb21ad WD |
178 | - Added the --inplace option that tells rsync to write each destination |
179 | file without using a temporary file. The matching of existing data | |
180 | in the destination file can be severely limited by this, but there | |
99d24f77 WD |
181 | are also cases where this is more efficient (such as appending data). |
182 | Use only when needed (see the man page for more details). | |
61fb21ad | 183 | |
86e2f445 | 184 | - Added the "write only" option for the daemon's config file. |
cbd85b47 | 185 | |
03a9ca0a | 186 | - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) |
831f05df | 187 | and documented all these options in the man page. |
03a9ca0a | 188 | |
ef0bc0ab WD |
189 | - Improved the handling of the --bwlimit option so that it's less |
190 | bursty, more accurate, and works properly over a larger range of | |
191 | values. | |
192 | ||
5b36173d WD |
193 | - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and |
194 | SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address. | |
195 | ||
bd1574b2 WD |
196 | - Added the --checksum-seed=N option for advanced users. |
197 | ||
bb3edc3b WD |
198 | - Batch writing/reading has a brand-new implementation that is simpler, |
199 | fixes a few weird problems with the old code (such as no longer | |
200 | sprinkling the batch files into different dirs or even onto different | |
201 | systems), and is much less intrusive into the code (making it easier | |
202 | to maintain for the future). The new code generates just one data | |
7fbc7031 | 203 | file instead of three, which makes it possible to read the batch on |
919ca3a3 | 204 | stdin via a remote shell. Also, the old requirement of forcing the |
82c6be7e | 205 | same fixed checksum-seed for all batch processing has been removed. |
0fac7fe8 | 206 | |
99d24f77 WD |
207 | - If an rsync daemon has a module set with "list = no" (which hides its |
208 | presence in the list of available modules), a user that fails to | |
209 | authenticate gets the same "unknown module" error that they would get | |
210 | if the module were actually unknown (while still logging the real | |
86e2f445 | 211 | error to the daemon's log file). This prevents fishing for module |
99d24f77 WD |
212 | names. |
213 | ||
86e2f445 WD |
214 | - The daemon's "refuse options" config item now allows you to match |
215 | option names using wildcards and/or the single-letter option names. | |
216 | ||
919ca3a3 WD |
217 | - Each transferred file now gets its permissions and modified-time |
218 | updated before the temp-file gets moved into place. Previously, the | |
219 | finished file would have a very brief window where its permissions | |
220 | disallowed all group and world access. | |
82c6be7e | 221 | |
a9ac4411 WD |
222 | - Added the ability to parse a literal IPv6 address in an "rsync:" URL |
223 | (e.g. rsync://[2001:638:500:101::21]:873/module/dir). | |
224 | ||
aa0ea373 WD |
225 | - The daemon's wildcard expanding code can now handle more than 1000 |
226 | filenames (it's now limited by memory instead of having a hard-wired | |
227 | limit). | |
228 | ||
03a9ca0a WD |
229 | INTERNAL: |
230 | ||
0058c58e WD |
231 | - Some cleanup in the exclude code has saved some per-exclude memory |
232 | and made the code easier to maintain. | |
03a9ca0a | 233 | |
82c6be7e WD |
234 | - Improved the argv-overflow checking for a remote command that has a |
235 | lot of args. | |
78112d30 | 236 | |
82c6be7e WD |
237 | - Use rsyserr() in the various places that were still calling rprintf() |
238 | with strerror() as an arg. | |
03a9ca0a | 239 | |
c54f5170 WD |
240 | - If an rsync daemon is listening on multiple sockets (to handle both |
241 | IPv4 and IPv6 to a single port), we now close all the unneeded file | |
40564811 | 242 | handles after we accept a connection (we used to close just one of |
c54f5170 WD |
243 | them). |
244 | ||
82c6be7e WD |
245 | - Optimized the handling of larger block sizes (rsync used to slow to a |
246 | crawl if the block size got too large). | |
65af3dab | 247 | |
c7b1a56b WD |
248 | - Optimized away a loop in hash_search(). |
249 | ||
82c6be7e WD |
250 | - Some improvements to the sanitize_path() and clean_fname() functions |
251 | makes them more efficient and produce better results (while still | |
252 | being compatible with the file-name cleaning that gets done on both | |
253 | sides when sending the file-list). | |
254 | ||
255 | - Got rid of alloc_sanitize_path() after adding a destination-buffer | |
256 | arg to sanitize_path() made it possible to put all the former's | |
257 | functionality into the latter. | |
258 | ||
7fbc7031 WD |
259 | - The file-list that is output when at least 4 verbose options are |
260 | specified reports the uid value on the sender even when rsync is | |
261 | not running as root (since we might be sending to a root receiver). | |
262 | ||
03a9ca0a WD |
263 | BUILD CHANGES: |
264 | ||
bd1574b2 WD |
265 | - Added a "gen" target to rebuild most of the generated files, |
266 | including configure, config.h.in, the man pages, and proto.h. | |
03a9ca0a | 267 | |
bd1574b2 | 268 | - If "make proto" doesn't find some changes in the prototypes, the |
40564811 | 269 | proto.h file is left untouched (its time-stamp used to always be |
40e8d11e | 270 | updated). |
03a9ca0a | 271 | |
c54f5170 WD |
272 | - The variable $STRIP (that is optionally set by the install-strip |
273 | target's rule) was changed to $INSTALL_STRIP because some systems | |
6c3fda83 | 274 | have $STRIP already set in the environment. |
c54f5170 | 275 | |
c7b1a56b WD |
276 | - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. |
277 | ||
6c3fda83 WD |
278 | - When cross-compiling, the gettimeofday() function is now assumed to |
279 | be a modern version that takes two-args (since we can't test it). | |
280 | ||
03a9ca0a WD |
281 | DEVELOPER RELATED: |
282 | ||
82c6be7e WD |
283 | - The scripts in the testsuite dir were cleaned up a bit and a few |
284 | new tests added. | |
03a9ca0a | 285 | |
eae4e1f9 | 286 | - Some new diffs were added to the patches dir, and some accepted |
40e8d11e | 287 | ones were removed. |
17f59e81 | 288 |
