1 | NEWS for rsync 2.6.3 (UNRELEASED) |
2 | Protocol: 28 (unchanged) | |
3 | Changes since 2.6.2: | |
4 | ||
5 | BUG FIXES: | |
6 | ||
831f05df WD |
7 | - Fixed a crash bug that might appear when --delete was used and |
8 | multiple source directories were specified. | |
03a9ca0a WD |
9 | |
10 | - The --backup code no longer attempts to create some directories | |
11 | over and over again (generating warnings along the way). | |
12 | ||
cbd85b47 WD |
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. | |
03a9ca0a WD |
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 | ||
cbd85b47 WD |
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 | ||
03a9ca0a WD |
28 | ENHANCEMENTS: |
29 | ||
cbd85b47 WD |
30 | - Added the "write only" option to the daemon's config file. |
31 | ||
03a9ca0a | 32 | - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) |
831f05df | 33 | and documented all these options in the man page. |
03a9ca0a WD |
34 | |
35 | INTERNAL: | |
36 | ||
37 | - Some cleanup in the exclude code has saved some memory and made | |
38 | things easier to maintain. | |
39 | ||
40 | - Use rsyserr() in the various places that were still calling | |
41 | rprintf() with strerror() as an arg. | |
42 | ||
43 | BUILD CHANGES: | |
44 | ||
45 | - Added a "gen" target to rebuild most of the various generated | |
46 | files, including configure, config.h.in, the man pages, and | |
47 | proto.h. | |
48 | ||
49 | - The timestamp of the proto.h file is unaltered by "make proto" | |
831f05df | 50 | if the contents don't change. |
03a9ca0a WD |
51 | |
52 | DEVELOPER RELATED: | |
53 | ||
54 | - The scripts in the testsuite dir were cleaned up a bit. | |

8752b3fc WD |
57 | Protocol: 28 (unchanged) |
58 | Changes since 2.6.1: | |
59 | ||
60 | BUG FIXES: | |
61 | ||
62 | - Fixed a major bug in the sorting of the filenames when --relative | |
d8195637 WD |
63 | is used for some sources (just sources such as "/" and "/*" were |
64 | affected). This fix ensures that we ask for the right file-list | |
65 | item when requesting changes from the sender. | |
8752b3fc WD |
66 | |
67 | - Rsync now checks the return value of the close() function to | |
68 | better report disk-full problems on an NFS file system. | |
69 | ||
70 | - Restored the old daemon-server behavior of logging error messages | |
71 | rather than returning them to the user. (A better long-term fix | |
72 | will be sought in the future.) | |
73 | ||
74 | - An obscure uninitialized-variable bug was fixed in the uid/gid | |
75 | code. (This bug probably had no ill effects.) | |
76 | ||
7561c3e1 WD |
77 | BUILD CHANGES: |
78 | ||
8752b3fc | 79 | - Got rid of the configure check for sys/sysctl.h (it wasn't used |
9130776c WD |
80 | and was causing a problem on some systems). Also improved the |
81 | broken-largefile-locking test to try to avoid failure due to an | |
82 | NFS build-dir. | |
8752b3fc | 83 | |
9130776c WD |
84 | - Fixed a compile problem on systems that don't define |
85 | AI_NUMERICHOST. | |
86 | ||
87 | - Fixed a compile problem in the popt source for compilers that | |
88 | don't support __attribute__. | |
89 | ||
7561c3e1 | 90 | DEVELOPER RELATED: |
9130776c WD |
91 | |
92 | - Improved the testsuite's "merge" test to work on OSF1. | |
8752b3fc WD |
93 | |
94 | - Two new diffs were added to the patches dir. | |

b3bc3110 | 98 | Protocol: 28 (changed) |
823edc68 WD |
99 | Changes since 2.6.0: |
100 | ||
c3046816 WD |
101 | SECURITY FIXES: |
102 | ||
103 | - Paths sent to an rsync daemon are more thoroughly sanitized when | |
104 | chroot is not used. If you're running a non-read-only rsync | |
105 | daemon with chroot disabled, *please upgrade*, ESPECIALLY if the | |
106 | user privs you run rsync under is anything above "nobody". | |
107 | ||
823edc68 WD |
108 | ENHANCEMENTS: |
109 | ||
c3046816 WD |
110 | - Lower memory use, more optimal transfer of data over the socket, |
111 | and lower CPU usage (see the INTERNAL section for details). | |
0a007489 | 112 | |
c3046816 | 113 | - The RSYNC_PROXY environment variable can now contain a |
823edc68 WD |
114 | "USER:PASS@" prefix before the "HOST:PORT" information. |
115 | (Bardur Arantsson) | |
116 | ||
c3046816 WD |
117 | - The --progress output now mentions how far along in the transfer |
118 | we are, including both a count of files transferred and a | |
119 | percentage of the total file-count that we've processed. It also | |
120 | shows better current-rate-of-transfer and remaining-transfer-time | |
121 | values. | |
b0a93231 | 122 | |
c3046816 WD |
123 | - Documentation changes now attempt to describe some often mis- |
124 | understood features more clearly. | |
fd489315 | 125 | |
823edc68 WD |
126 | BUG FIXES: |
127 | ||
c3046816 WD |
128 | - When -x (--one-file-system) is combined with -L (--copy-links) or |
129 | --copy-unsafe-links, no symlinked files are skipped, even if the | |
130 | referent file is on a different filesystem. | |
6609a9f1 | 131 | |
c3046816 WD |
132 | - The --link-dest code now works properly for a non-root user when |
133 | (1) the UIDs of the source and destination differ and -o was | |
134 | specified, or (2) when the group of the source can't be used on | |
135 | the destination and -g was specified. | |
823edc68 | 136 | |
c3046816 WD |
137 | - Fixed a bug in the handling of -H (hard-links) that might cause |
138 | the expanded PATH/NAME value of the current item to get | |
139 | overwritten (due to an expanded-name caching bug). | |
823edc68 | 140 | |
c3046816 WD |
141 | - We now reset the "new data has been sent" flag at the start of |
142 | each file we send. This makes sure that an interrupted transfer | |
143 | with the --partial option set doesn't keep a shorter temp file | |
144 | than the current basis file when no new data has been transfered | |
145 | over the wire for that file. | |
146 | ||
147 | - Fixed a byte-order problem in --batch-mode on big-endian machines. | |
148 | (Jay Fenlason) | |
149 | ||
c3046816 WD |
150 | - When using --cvs-exclude, the exclude items we get from a |
151 | per-directory's .cvsignore file once again only affect that one | |
152 | directory (not all following directories too). The items are also | |
153 | now properly word-split and parsed without any +/- prefix parsing. | |
154 | ||
155 | - When specifying the USER@HOST: prefix for a file, the USER part | |
156 | can now contain an '@', if needed (i.e. the last '@' is used to | |
157 | find the HOST, not the first). | |
158 | ||
159 | - Fixed some bugs in the handling of group IDs for non-root users: | |
160 | (1) It properly handles a group that the sender didn't have a name | |
161 | for (it would previously skip changing the group on any files in | |
162 | that group). (2) If --numeric-ids is used, rsync no longer | |
163 | attempts to set groups that the user doesn't have the permission | |
164 | to set. | |
165 | ||
166 | - Fixed the "refuse options" setting in the rsyncd.conf file. | |
167 | ||
168 | - Improved the -x (--one-file-system) flag's handling of any mount- | |
169 | point directories we encounter. It is both more optimal (in that | |
170 | it no longer does a useless scan of the contents of the mount- | |
171 | point dirs) and also fixes a bug where a remapped mount of the | |
172 | original filesystem could get discovered in a subdir we should be | |
173 | ignoring. | |
174 | ||
175 | - Rsync no longer discards a double-slash at the start of a filename | |
89afe532 | 176 | when trying to open the file. It also no longer constructs names |
b3bc3110 | 177 | that start with a double slash (unless the user supplied them). |
89afe532 | 178 | |
c3046816 | 179 | - Path-specifying options to a daemon should now work the same with |
de31639f WD |
180 | or without chroot turned on. Previously, such a option (such as |
181 | --link-dest) would get its absolute path munged into a relative | |
182 | one if chroot was not on, making that setting fairly useless. | |
183 | Rsync now transforms the path into one that is based on the | |
184 | module's base dir when chroot is not enabled. | |
8b463409 | 185 | |
c3046816 | 186 | - Fixed a compatibility problem interacting with older rsync |
8b463409 WD |
187 | versions that might send us an empty --suffix value without |
188 | telling us that --backup-dir was specified. | |
b1ad6a32 | 189 | |
c3046816 WD |
190 | - The "hosts allow" option for a daemon-over-remote-shell process |
191 | now has improved support for IPv6 addresses and a fix for systems | |
192 | that have a length field in their socket structs. | |
b1ad6a32 | 193 | |
c3046816 WD |
194 | - Fixed the ability to request an empty backup --suffix when sending |
195 | files to an rsync daemon. | |

197 | INTERNAL: |

c3046816 WD |
199 | - Most of the I/O is now buffered, which results in a pretty large |
200 | speedup when running under MS Windows. (Craig Barratt) | |
823edc68 | 201 | |
c3046816 WD |
202 | - Optimizations to the name-handling/comparing code have made some |
203 | significant reductions in user-CPU time for large file sets. | |
823edc68 | 204 | |
c3046816 | 205 | - Some cleanup of the variable types make the code more consistent. |
31e7451a | 206 | |
c3046816 | 207 | - Reduced memory requirements of hard link preservation. |
0a007489 | 208 | (J.W. Schultz) |
279b1c1e | 209 | |
c3046816 WD |
210 | - Implemented a new algorithm for hard-link handling that speeds up |
211 | the code significantly. (J.W. Schultz and Wayne Davison) | |
f8ebdf92 | 212 | |
c3046816 | 213 | - The --hard-link option now uses the first existing file in the |
64f21c31 WD |
214 | group of linked files as the basis for the transfer. This |
215 | prevents the sub-optimal transfer of a file's data when a new | |
216 | hardlink is added on the sending side and it sorts alphabetically | |
217 | earlier in the list than the files that are already present on the | |
218 | receiving side. | |
219 | ||
c3046816 WD |
220 | - Dropped support for protocol versions less than 20 (2.3.0 released |
221 | 15 Mar 1999) and activated warnings for protocols less than 25 | |
222 | (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz, | |
223 | severally) | |
aa953c32 | 224 | |
c3046816 | 225 | - More optimal data transmission for --hard-links (protocol 28). |
1a62c49d | 226 | |
c3046816 | 227 | - More optimal data transmission for --checksum (protocol 28). |
1a62c49d | 228 | |
c3046816 | 229 | - Less memory is used when --checksum is specified. |
1a62c49d | 230 | |
c3046816 | 231 | - Less memory is used in the file list (a per-file savings). |
0a007489 | 232 | |
c3046816 | 233 | - The generator is now better about not modifying the file list |
b2181306 WD |
234 | during the transfer in order to avoid a copy-on-write memory |
235 | bifurcation (on systems where fork() uses shared memory). | |
236 | Previously, rsync's shared memory would slowly become unshared, | |
237 | resulting in real memory usage nearly doubling on the receiving | |
238 | side by the end of the transfer. Now, as long as permissions | |
239 | are being preserved, the shared memory should remain that way | |
240 | for the entire transfer. | |
241 | ||
c3046816 WD |
242 | - Changed hardlink info and file_struct + strings to use allocation |
243 | pools. This reduces memory use for large file-sets and permits | |
244 | freeing memory to the OS. (J.W. Schultz) | |
b0a93231 | 245 | |
c3046816 WD |
246 | - The 2 pipes used between the receiver and generator processes |
247 | (which are forked on the same machine) were reduced to 1 pipe and | |
248 | the protocol improved so that (1) it is now impossible to have the | |
249 | "redo" pipe fill up and hang rsync, and (2) trailing messages from | |
250 | the receiver don't get lost on their way through the generator | |
251 | over to the sender (which mainly affected hard-link messages and | |
252 | verbose --stats output). | |
442743b8 | 253 | |
c3046816 WD |
254 | - Improved the internal uid/gid code to be more portable and a |
255 | little more optimized. | |
79d40530 | 256 | |
c3046816 | 257 | - The device numbers sent when using --devices are now sent as |
d008bcb5 WD |
258 | separate major/minor values with 32-bit accuracy (protocol 28). |
259 | Previously, the copied devices were sent as a single 32-bit | |
260 | number. This will make inter-operation of 64-bit binaries more | |
c3046816 WD |
261 | compatible with their 32-bit brethren (with both ends of the |
262 | connection are using protocol 28). Note that optimizations in the | |
263 | binary protocol for sending the device numbers often results in | |
264 | fewer bytes being used than before, even though more precision is | |
265 | now available. | |
266 | ||
267 | - Some cleanup of the exclude/include structures and its code made | |
268 | things clearer (internally), simpler, and more efficient. | |
269 | ||
270 | - The reading & writing of the file-list in batch-mode is now | |
271 | handled by the same code that sends & receives the list over the | |
272 | wire. This makes it much easier to maintain. (Note that the | |
273 | batch code is still considered to be experimental.) | |
7561c3e1 WD |
274 | |
275 | BUILD CHANGES: | |
276 | ||
277 | - The configure script now accepts --with-rsyncd-conf=PATH to | |
278 | override the default value of the /etc/rsyncd.conf file. | |
279 | ||
280 | - Fixed configure bug when running "./configure --disable-ipv6". | |
281 | ||
282 | - Fixed compilation problem on Tru64 Unix (having to do with | |
283 | sockaddr.sa_len and sockaddr.sin_len). | |
284 | ||
285 | DEVELOPER RELATED: | |
286 | ||
287 | - Fixed "make test" bug when build dir is not the source dir. | |
288 | ||
289 | - Added a couple extra diffs in the "patches" dir, removed the ones | |
290 | that got applied, and rebuilt the rest. | |
291 |
