a3571c6c | 1 | NEWS for rsync 2.6.3 (30 Sep 2004) |
03a9ca0a WD |
2 | Protocol: 28 (unchanged) |
3 | Changes since 2.6.2: | |
4 | ||
8fb7db24 WD |
5 | SECURITY FIXES: |
6 | ||
7 | - A bug in the sanitize_path routine (which affects a non-chrooted | |
d414962a WD |
8 | rsync daemon) could allow a user to craft a pathname that would get |
9 | transformed into an absolute path for certain options (but not for | |
919ca3a3 | 10 | file-transfer names). If you're running an rsync daemon with chroot |
d414962a WD |
11 | disabled, *please upgrade*, ESPECIALLY if the user privs you run |
12 | rsync under is anything above "nobody". | |
8fb7db24 | 13 | |
f6c0d3d7 WD |
14 | OUTPUT CHANGES (ATTN: those using a script to parse the verbose output): |
15 | ||
16 | - Please note that the 2-line footer (output when verbose) now uses the | |
17 | term "sent" instead of "wrote" and "received" instead of "read". If | |
18 | you are not parsing the numeric values out of this footer, a script | |
82c6be7e | 19 | would be better off using the empty line prior to the footer as the |
f6c0d3d7 | 20 | indicator that the verbose output is over. |
446a2987 | 21 | |
f6c0d3d7 WD |
22 | - The output from the --stats option was similarly affected to change |
23 | "written" to "sent" and "read" to "received". | |
24 | ||
82c6be7e WD |
25 | - Rsync ensures that a filename that contains a newline gets mentioned |
26 | with each newline transformed into a question mark (which prevents a | |
27 | filename from causing an empty line to be output). | |
446a2987 | 28 | |
a3571c6c WD |
29 | - The "backed up ..." message that is output when at least 2 --verbose |
30 | options are specified is now the same both with and without the | |
31 | --backup-dir option. | |
32 | ||
03a9ca0a WD |
33 | BUG FIXES: |
34 | ||
831f05df WD |
35 | - Fixed a crash bug that might appear when --delete was used and |
36 | multiple source directories were specified. | |
03a9ca0a | 37 | |
6c3fda83 | 38 | - Fixed a 32-bit truncation of the file length when generating the |
c7b1a56b WD |
39 | checksums. |
40 | ||
03a9ca0a WD |
41 | - The --backup code no longer attempts to create some directories |
42 | over and over again (generating warnings along the way). | |
43 | ||
cbd85b47 WD |
44 | - Fixed a bug in the reading of the secrets file (by the daemon) and |
45 | the password file (by the client): the files no longer need to be | |
46 | terminated by a newline for their content to be read in. | |
03a9ca0a | 47 | |
99d24f77 WD |
48 | - If a file has a read error on the sending side or the reconstructed |
49 | data doesn't match the expected checksum (perhaps due to the basis | |
50 | file changing during the transfer), the receiver will no longer | |
51 | retain the resulting file unless the --partial option was specified. | |
52 | (Note: for the read-error detection to work, neither side can be | |
53 | older than 2.6.3 -- older receivers will always retain the file, and | |
54 | older senders don't tell the receiver that the file had a read | |
55 | error.) | |
03a9ca0a | 56 | |
c54f5170 | 57 | - If a file gets resent in a single transfer and the --backup option |
82c6be7e WD |
58 | is enabled, rsync no longer performs a duplicate backup (it used to |
59 | overwrite the original file in the backup area). | |
03a9ca0a | 60 | |
cbd85b47 | 61 | - Files specified in the daemon's "exclude" or "exclude from" config |
bd1574b2 WD |
62 | items are now excluded from being uploaded (assuming that the module |
63 | allows uploading at all) in addition to the old download exclusion. | |
cbd85b47 | 64 | |
40e8d11e WD |
65 | - Got rid of a potential hang in the receiver when near the end of a |
66 | phase. | |
67 | ||
b03bded7 WD |
68 | - When using --backup without a --backup-dir, rsync no longer preserves |
69 | the modify time on directories. This avoids confusing NFS. | |
70 | ||
40e8d11e WD |
71 | - When --copy-links (-L) is specified, we now output a separate error |
72 | for a symlink that has no referent instead of claiming that a file | |
73 | "vanished". | |
74 | ||
f6c0d3d7 WD |
75 | - The --copy-links (-L) option no longer has the side-effect of telling |
76 | the receiving side to follow symlinks. See the --keep-dirlinks | |
77 | option (mentioned below) for a way to specify that behavior. | |
78 | ||
2c2898a3 | 79 | - Error messages from the daemon server's option-parsing (such as |
6c3fda83 WD |
80 | refused options) are now successfully transferred back to the client |
81 | (the server used to fail to send the message because the socket | |
82 | wasn't in the right state for the message to get through). | |
2c2898a3 | 83 | |
6c3fda83 WD |
84 | - Most transfer errors that occur during a daemon transfer are now |
85 | returned to the user in addition to being logged (some messages are | |
86 | intended to be daemon-only and are not affected by this). | |
c54f5170 | 87 | |
b03bded7 WD |
88 | - Fixed a bug in the daemon authentication code when using one of the |
89 | batch-processing options. | |
90 | ||
40564811 WD |
91 | - We try to work around some buggy IPv6 implementations that fail to |
92 | implement IPV6_V6ONLY. This should fix the "address in use" error | |
93 | that some daemons get when running on an OS with a buggy IPv6 | |
94 | implementation. Also, if the new code gets this error, we might | |
95 | suggest that the user specify --ipv4 or --ipv6 (if we think it will | |
96 | help). | |
97 | ||
65af3dab | 98 | - When the remote rsync dies, make a better effort to recover any error |
86e2f445 WD |
99 | messages it may have sent before dying (the local rsync used to just |
100 | die with a socket-write error). | |
65af3dab WD |
101 | |
102 | - When using --delete and a --backup-dir that contains files that are | |
103 | hard-linked to their destination equivalents, rsync now makes sure | |
6c3fda83 WD |
104 | that removed files really get removed (avoids a really weird rename() |
105 | behavior). | |
65af3dab WD |
106 | |
107 | - Avoid a bogus run-time complaint about a lack of 64-bit integers when | |
99d24f77 | 108 | the int64 type is defined as an off_t and it actually has 64-bits. |
65af3dab | 109 | |
00735149 WD |
110 | - Added a configure check for open64() without mkstemp64() so that we |
111 | can avoid using mkstemp() when such a combination is encountered. | |
112 | This bypasses a problem writing out large temp files on OSes such as | |
113 | AIX and HP-UX. | |
114 | ||
82c6be7e WD |
115 | - Fixed an age-old crash problem with --read-batch on a local copy |
116 | (rsync was improperly assuming --whole-file for the local copy). | |
117 | ||
118 | - When --dry-run (-n) is used and the destination directory does not | |
119 | exist, rsync now produces a correct report of files that would be | |
120 | sent instead of dying with a chdir() error. | |
121 | ||
37c36e26 WD |
122 | - Fixed a bug that could cause a slow-to-connect rsync daemon to die |
123 | with an error instead of waiting for the connection to finish. | |
124 | ||
a3571c6c WD |
125 | - Fixed an ssh interaction that could cause output to be lost when the |
126 | user chose to combine the output of rsync's stdout and stderr (e.g. | |
127 | using the "2>&1"). | |
128 | ||
03a9ca0a WD |
129 | ENHANCEMENTS: |
130 | ||
65af3dab WD |
131 | - Added the --partial-dir=DIR option that lets you specify where to |
132 | (temporarily) put a partially transferred file (instead of over- | |
133 | writing the destination file). E.g. --partial-dir=.rsync-partial | |
cc07f212 WD |
134 | Also added support for the RSYNC_PARTIAL_DIR environment variable |
135 | that, when found, transforms a regular --partial option (such as | |
136 | the convenient -P option) into one that also specifies a directory. | |
65af3dab | 137 | |
40e8d11e | 138 | - Added --keep-dirlinks (-K), which allows you to symlink a directory |
40564811 | 139 | onto another partition on the receiving side and have rsync treat it |
4e1f3857 WD |
140 | as matching a normal directory from the sender. |
141 | ||
61fb21ad WD |
142 | - Added the --inplace option that tells rsync to write each destination |
143 | file without using a temporary file. The matching of existing data | |
144 | in the destination file can be severely limited by this, but there | |
99d24f77 WD |
145 | are also cases where this is more efficient (such as appending data). |
146 | Use only when needed (see the man page for more details). | |
61fb21ad | 147 | |
86e2f445 | 148 | - Added the "write only" option for the daemon's config file. |
cbd85b47 | 149 | |
03a9ca0a | 150 | - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) |
831f05df | 151 | and documented all these options in the man page. |
03a9ca0a | 152 | |
ef0bc0ab WD |
153 | - Improved the handling of the --bwlimit option so that it's less |
154 | bursty, more accurate, and works properly over a larger range of | |
155 | values. | |
156 | ||
5b36173d WD |
157 | - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and |
158 | SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address. | |
159 | ||
bd1574b2 WD |
160 | - Added the --checksum-seed=N option for advanced users. |
161 | ||
bb3edc3b WD |
162 | - Batch writing/reading has a brand-new implementation that is simpler, |
163 | fixes a few weird problems with the old code (such as no longer | |
164 | sprinkling the batch files into different dirs or even onto different | |
165 | systems), and is much less intrusive into the code (making it easier | |
166 | to maintain for the future). The new code generates just one data | |
7fbc7031 | 167 | file instead of three, which makes it possible to read the batch on |
919ca3a3 | 168 | stdin via a remote shell. Also, the old requirement of forcing the |
82c6be7e | 169 | same fixed checksum-seed for all batch processing has been removed. |
0fac7fe8 | 170 | |
99d24f77 WD |
171 | - If an rsync daemon has a module set with "list = no" (which hides its |
172 | presence in the list of available modules), a user that fails to | |
173 | authenticate gets the same "unknown module" error that they would get | |
174 | if the module were actually unknown (while still logging the real | |
86e2f445 | 175 | error to the daemon's log file). This prevents fishing for module |
99d24f77 WD |
176 | names. |
177 | ||
86e2f445 WD |
178 | - The daemon's "refuse options" config item now allows you to match |
179 | option names using wildcards and/or the single-letter option names. | |
180 | ||
919ca3a3 WD |
181 | - Each transferred file now gets its permissions and modified-time |
182 | updated before the temp-file gets moved into place. Previously, the | |
183 | finished file would have a very brief window where its permissions | |
184 | disallowed all group and world access. | |
82c6be7e | 185 | |
a9ac4411 WD |
186 | - Added the ability to parse a literal IPv6 address in an "rsync:" URL |
187 | (e.g. rsync://[2001:638:500:101::21]:873/module/dir). | |
188 | ||
aa0ea373 WD |
189 | - The daemon's wildcard expanding code can now handle more than 1000 |
190 | filenames (it's now limited by memory instead of having a hard-wired | |
191 | limit). | |
192 | ||
03a9ca0a WD |
193 | INTERNAL: |
194 | ||
0058c58e WD |
195 | - Some cleanup in the exclude code has saved some per-exclude memory |
196 | and made the code easier to maintain. | |
03a9ca0a | 197 | |
82c6be7e WD |
198 | - Improved the argv-overflow checking for a remote command that has a |
199 | lot of args. | |
78112d30 | 200 | |
82c6be7e WD |
201 | - Use rsyserr() in the various places that were still calling rprintf() |
202 | with strerror() as an arg. | |
03a9ca0a | 203 | |
c54f5170 WD |
204 | - If an rsync daemon is listening on multiple sockets (to handle both |
205 | IPv4 and IPv6 to a single port), we now close all the unneeded file | |
40564811 | 206 | handles after we accept a connection (we used to close just one of |
c54f5170 WD |
207 | them). |
208 | ||
82c6be7e WD |
209 | - Optimized the handling of larger block sizes (rsync used to slow to a |
210 | crawl if the block size got too large). | |
65af3dab | 211 | |
c7b1a56b WD |
212 | - Optimized away a loop in hash_search(). |
213 | ||
82c6be7e WD |
214 | - Some improvements to the sanitize_path() and clean_fname() functions |
215 | makes them more efficient and produce better results (while still | |
216 | being compatible with the file-name cleaning that gets done on both | |
217 | sides when sending the file-list). | |
218 | ||
219 | - Got rid of alloc_sanitize_path() after adding a destination-buffer | |
220 | arg to sanitize_path() made it possible to put all the former's | |
221 | functionality into the latter. | |
222 | ||
7fbc7031 WD |
223 | - The file-list that is output when at least 4 verbose options are |
224 | specified reports the uid value on the sender even when rsync is | |
225 | not running as root (since we might be sending to a root receiver). | |
226 | ||
03a9ca0a WD |
227 | BUILD CHANGES: |
228 | ||
bd1574b2 WD |
229 | - Added a "gen" target to rebuild most of the generated files, |
230 | including configure, config.h.in, the man pages, and proto.h. | |
03a9ca0a | 231 | |
bd1574b2 | 232 | - If "make proto" doesn't find some changes in the prototypes, the |
40564811 | 233 | proto.h file is left untouched (its time-stamp used to always be |
40e8d11e | 234 | updated). |
03a9ca0a | 235 | |
c54f5170 WD |
236 | - The variable $STRIP (that is optionally set by the install-strip |
237 | target's rule) was changed to $INSTALL_STRIP because some systems | |
6c3fda83 | 238 | have $STRIP already set in the environment. |
c54f5170 | 239 | |
c7b1a56b WD |
240 | - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. |
241 | ||
6c3fda83 WD |
242 | - When cross-compiling, the gettimeofday() function is now assumed to |
243 | be a modern version that takes two-args (since we can't test it). | |
244 | ||
03a9ca0a WD |
245 | DEVELOPER RELATED: |
246 | ||
82c6be7e WD |
247 | - The scripts in the testsuite dir were cleaned up a bit and a few |
248 | new tests added. | |
03a9ca0a | 249 | |
eae4e1f9 | 250 | - Some new diffs were added to the patches dir, and some accepted |
40e8d11e | 251 | ones were removed. |
17f59e81 | 252 |
