1 | NEWS for rsync 2.6.3 (UNRELEASED) |
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". | |

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). | |

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