1NEWS for rsync 2.6.3 (UNRELEASED)
2Protocol: 28 (unchanged)
3Changes since 2.6.2:
4
5 BUG FIXES:
6
7 - Fixed a crash bug that might appear when --delete was used and
8 multiple source directories were specified.
9
10 - The --backup code no longer attempts to create some directories
11 over and over again (generating warnings along the way).
12
13 - Fixed a bug in the reading of the secrets file (by the daemon) and
14 the password file (by the client): the files no longer need to be
15 terminated by a newline for their content to be read in.
16
17 - If a file has a read error on the sending side, the receiver will
18 no longer keep the resulting file unless the --partial option was
19 specified.
20
21 - Fixed an age-old crash problem with --read-batch on a local copy
22 (rsync was improperly assuming --whole-file for the local copy).
23
24 - Files specified in the daemon's "exclude" or "exclude from" config
25 items are now excluded from being uploaded (if the module is not
26 read-only) as well as downloaded.
27
28 - When using --backup without a --backup-dir, rsync no longer preserves
29 the modify time on directories. This avoids confusing NFS.
30
31 - Fixed a bug in the daemon authentication code when using one of the
32 batch-processing options.
33
34 ENHANCEMENTS:
35
36 - Added the "write only" option to the daemon's config file.
37
38 - Added the --checksum-seed=N option for advanced users.
39
40 - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
41 and documented all these options in the man page.
42
43 INTERNAL:
44
45 - Some cleanup in the exclude code has saved some memory and made
46 things easier to maintain.
47
48 - Use rsyserr() in the various places that were still calling
49 rprintf() with strerror() as an arg.
50
51 BUILD CHANGES:
52
53 - Added a "gen" target to rebuild most of the various generated
54 files, including configure, config.h.in, the man pages, and
55 proto.h.
56
57 - The timestamp of the proto.h file is unaltered by "make proto"
58 if the contents don't change.
59
60 DEVELOPER RELATED:
61
62 - The scripts in the testsuite dir were cleaned up a bit.

64NEWS for rsync 2.6.2 (30 Apr 2004)
65Protocol: 28 (unchanged)
66Changes since 2.6.1:
67
68 BUG FIXES:
69
70 - Fixed a major bug in the sorting of the filenames when --relative
71 is used for some sources (just sources such as "/" and "/*" were
72 affected). This fix ensures that we ask for the right file-list
73 item when requesting changes from the sender.
74
75 - Rsync now checks the return value of the close() function to
76 better report disk-full problems on an NFS file system.
77
78 - Restored the old daemon-server behavior of logging error messages
79 rather than returning them to the user. (A better long-term fix
80 will be sought in the future.)
81
82 - An obscure uninitialized-variable bug was fixed in the uid/gid
83 code. (This bug probably had no ill effects.)
84
85 BUILD CHANGES:
86
87 - Got rid of the configure check for sys/sysctl.h (it wasn't used
88 and was causing a problem on some systems). Also improved the
89 broken-largefile-locking test to try to avoid failure due to an
90 NFS build-dir.
91
92 - Fixed a compile problem on systems that don't define
93 AI_NUMERICHOST.
94
95 - Fixed a compile problem in the popt source for compilers that
96 don't support __attribute__.
97
98 DEVELOPER RELATED:
99
100 - Improved the testsuite's "merge" test to work on OSF1.
101
102 - Two new diffs were added to the patches dir.

105NEWS for rsync 2.6.1 (26 Apr 2004)
106Protocol: 28 (changed)
107Changes since 2.6.0:
108
109 SECURITY FIXES:
110
111 - Paths sent to an rsync daemon are more thoroughly sanitized when
112 chroot is not used. If you're running a non-read-only rsync
113 daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
114 user privs you run rsync under is anything above "nobody".
115
116 ENHANCEMENTS:
117
118 - Lower memory use, more optimal transfer of data over the socket,
119 and lower CPU usage (see the INTERNAL section for details).
120
121 - The RSYNC_PROXY environment variable can now contain a
122 "USER:PASS@" prefix before the "HOST:PORT" information.
123 (Bardur Arantsson)
124
125 - The --progress output now mentions how far along in the transfer
126 we are, including both a count of files transferred and a
127 percentage of the total file-count that we've processed. It also
128 shows better current-rate-of-transfer and remaining-transfer-time
129 values.
130
131 - Documentation changes now attempt to describe some often mis-
132 understood features more clearly.
133
134 BUG FIXES:
135
136 - When -x (--one-file-system) is combined with -L (--copy-links) or
137 --copy-unsafe-links, no symlinked files are skipped, even if the
138 referent file is on a different filesystem.
139
140 - The --link-dest code now works properly for a non-root user when
141 (1) the UIDs of the source and destination differ and -o was
142 specified, or (2) when the group of the source can't be used on
143 the destination and -g was specified.
144
145 - Fixed a bug in the handling of -H (hard-links) that might cause
146 the expanded PATH/NAME value of the current item to get
147 overwritten (due to an expanded-name caching bug).
148
149 - We now reset the "new data has been sent" flag at the start of
150 each file we send. This makes sure that an interrupted transfer
151 with the --partial option set doesn't keep a shorter temp file
152 than the current basis file when no new data has been transfered
153 over the wire for that file.
154
155 - Fixed a byte-order problem in --batch-mode on big-endian machines.
156 (Jay Fenlason)
157
158 - When using --cvs-exclude, the exclude items we get from a
159 per-directory's .cvsignore file once again only affect that one
160 directory (not all following directories too). The items are also
161 now properly word-split and parsed without any +/- prefix parsing.
162
163 - When specifying the USER@HOST: prefix for a file, the USER part
164 can now contain an '@', if needed (i.e. the last '@' is used to
165 find the HOST, not the first).
166
167 - Fixed some bugs in the handling of group IDs for non-root users:
168 (1) It properly handles a group that the sender didn't have a name
169 for (it would previously skip changing the group on any files in
170 that group). (2) If --numeric-ids is used, rsync no longer
171 attempts to set groups that the user doesn't have the permission
172 to set.
173
174 - Fixed the "refuse options" setting in the rsyncd.conf file.
175
176 - Improved the -x (--one-file-system) flag's handling of any mount-
177 point directories we encounter. It is both more optimal (in that
178 it no longer does a useless scan of the contents of the mount-
179 point dirs) and also fixes a bug where a remapped mount of the
180 original filesystem could get discovered in a subdir we should be
181 ignoring.
182
183 - Rsync no longer discards a double-slash at the start of a filename
184 when trying to open the file. It also no longer constructs names
185 that start with a double slash (unless the user supplied them).
186
187 - Path-specifying options to a daemon should now work the same with
188 or without chroot turned on. Previously, such a option (such as
189 --link-dest) would get its absolute path munged into a relative
190 one if chroot was not on, making that setting fairly useless.
191 Rsync now transforms the path into one that is based on the
192 module's base dir when chroot is not enabled.
193
194 - Fixed a compatibility problem interacting with older rsync
195 versions that might send us an empty --suffix value without
196 telling us that --backup-dir was specified.
197
198 - The "hosts allow" option for a daemon-over-remote-shell process
199 now has improved support for IPv6 addresses and a fix for systems
200 that have a length field in their socket structs.
201
202 - Fixed the ability to request an empty backup --suffix when sending
203 files to an rsync daemon.
204
205 INTERNAL:
206
207 - Most of the I/O is now buffered, which results in a pretty large
208 speedup when running under MS Windows. (Craig Barratt)
209
210 - Optimizations to the name-handling/comparing code have made some
211 significant reductions in user-CPU time for large file sets.
212
213 - Some cleanup of the variable types make the code more consistent.
214
215 - Reduced memory requirements of hard link preservation.
216 (J.W. Schultz)
217
218 - Implemented a new algorithm for hard-link handling that speeds up
219 the code significantly. (J.W. Schultz and Wayne Davison)
220
221 - The --hard-link option now uses the first existing file in the
222 group of linked files as the basis for the transfer. This
223 prevents the sub-optimal transfer of a file's data when a new
224 hardlink is added on the sending side and it sorts alphabetically
225 earlier in the list than the files that are already present on the
226 receiving side.
227
228 - Dropped support for protocol versions less than 20 (2.3.0 released
229 15 Mar 1999) and activated warnings for protocols less than 25
230 (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
231 severally)
232
233 - More optimal data transmission for --hard-links (protocol 28).
234
235 - More optimal data transmission for --checksum (protocol 28).
236
237 - Less memory is used when --checksum is specified.
238
239 - Less memory is used in the file list (a per-file savings).
240
241 - The generator is now better about not modifying the file list
242 during the transfer in order to avoid a copy-on-write memory
243 bifurcation (on systems where fork() uses shared memory).
244 Previously, rsync's shared memory would slowly become unshared,
245 resulting in real memory usage nearly doubling on the receiving
246 side by the end of the transfer. Now, as long as permissions
247 are being preserved, the shared memory should remain that way
248 for the entire transfer.
249
250 - Changed hardlink info and file_struct + strings to use allocation
251 pools. This reduces memory use for large file-sets and permits
252 freeing memory to the OS. (J.W. Schultz)
253
254 - The 2 pipes used between the receiver and generator processes
255 (which are forked on the same machine) were reduced to 1 pipe and
256 the protocol improved so that (1) it is now impossible to have the
257 "redo" pipe fill up and hang rsync, and (2) trailing messages from
258 the receiver don't get lost on their way through the generator
259 over to the sender (which mainly affected hard-link messages and
260 verbose --stats output).
261
262 - Improved the internal uid/gid code to be more portable and a
263 little more optimized.
264
265 - The device numbers sent when using --devices are now sent as
266 separate major/minor values with 32-bit accuracy (protocol 28).
267 Previously, the copied devices were sent as a single 32-bit
268 number. This will make inter-operation of 64-bit binaries more
269 compatible with their 32-bit brethren (with both ends of the
270 connection are using protocol 28). Note that optimizations in the
271 binary protocol for sending the device numbers often results in
272 fewer bytes being used than before, even though more precision is
273 now available.
274
275 - Some cleanup of the exclude/include structures and its code made
276 things clearer (internally), simpler, and more efficient.
277
278 - The reading & writing of the file-list in batch-mode is now
279 handled by the same code that sends & receives the list over the
280 wire. This makes it much easier to maintain. (Note that the
281 batch code is still considered to be experimental.)
282
283 BUILD CHANGES:
284
285 - The configure script now accepts --with-rsyncd-conf=PATH to
286 override the default value of the /etc/rsyncd.conf file.
287
288 - Fixed configure bug when running "./configure --disable-ipv6".
289
290 - Fixed compilation problem on Tru64 Unix (having to do with
291 sockaddr.sa_len and sockaddr.sin_len).
292
293 DEVELOPER RELATED:
294
295 - Fixed "make test" bug when build dir is not the source dir.
296
297 - Added a couple extra diffs in the "patches" dir, removed the ones
298 that got applied, and rebuilt the rest.
