9130776c | 1 | NEWS for rsync 2.6.2 (30 Apr 2004) |
8752b3fc WD |
2 | Protocol: 28 (unchanged) |
3 | Changes since 2.6.1: | |
4 | ||
5 | BUG FIXES: | |
6 | ||
7 | - Fixed a major bug in the sorting of the filenames when --relative | |
d8195637 WD |
8 | is used for some sources (just sources such as "/" and "/*" were |
9 | affected). This fix ensures that we ask for the right file-list | |
10 | item when requesting changes from the sender. | |
8752b3fc WD |
11 | |
12 | - Rsync now checks the return value of the close() function to | |
13 | better report disk-full problems on an NFS file system. | |
14 | ||
15 | - Restored the old daemon-server behavior of logging error messages | |
16 | rather than returning them to the user. (A better long-term fix | |
17 | will be sought in the future.) | |
18 | ||
19 | - An obscure uninitialized-variable bug was fixed in the uid/gid | |
20 | code. (This bug probably had no ill effects.) | |
21 | ||
7561c3e1 WD |
22 | BUILD CHANGES: |
23 | ||
8752b3fc | 24 | - Got rid of the configure check for sys/sysctl.h (it wasn't used |
9130776c WD |
25 | and was causing a problem on some systems). Also improved the |
26 | broken-largefile-locking test to try to avoid failure due to an | |
27 | NFS build-dir. | |
8752b3fc | 28 | |
9130776c WD |
29 | - Fixed a compile problem on systems that don't define |
30 | AI_NUMERICHOST. | |
31 | ||
32 | - Fixed a compile problem in the popt source for compilers that | |
33 | don't support __attribute__. | |
34 | ||
7561c3e1 | 35 | DEVELOPER RELATED: |
9130776c WD |
36 | |
37 | - Improved the testsuite's "merge" test to work on OSF1. | |
8752b3fc WD |
38 | |
39 | - Two new diffs were added to the patches dir. | |

c3046816 | 42 | NEWS for rsync 2.6.1 (26 Apr 2004) |
b3bc3110 | 43 | Protocol: 28 (changed) |
823edc68 WD |
44 | Changes since 2.6.0: |
45 | ||
c3046816 WD |
46 | SECURITY FIXES: |
47 | ||
48 | - Paths sent to an rsync daemon are more thoroughly sanitized when | |
49 | chroot is not used. If you're running a non-read-only rsync | |
50 | daemon with chroot disabled, *please upgrade*, ESPECIALLY if the | |
51 | user privs you run rsync under is anything above "nobody". | |
52 | ||
823edc68 WD |
53 | ENHANCEMENTS: |
54 | ||
c3046816 WD |
55 | - Lower memory use, more optimal transfer of data over the socket, |
56 | and lower CPU usage (see the INTERNAL section for details). | |
0a007489 | 57 | |
c3046816 | 58 | - The RSYNC_PROXY environment variable can now contain a |
823edc68 WD |
59 | "USER:PASS@" prefix before the "HOST:PORT" information. |
60 | (Bardur Arantsson) | |
61 | ||
c3046816 WD |
62 | - The --progress output now mentions how far along in the transfer |
63 | we are, including both a count of files transferred and a | |
64 | percentage of the total file-count that we've processed. It also | |
65 | shows better current-rate-of-transfer and remaining-transfer-time | |
66 | values. | |
b0a93231 | 67 | |
c3046816 WD |
68 | - Documentation changes now attempt to describe some often mis- |
69 | understood features more clearly. | |
fd489315 | 70 | |
823edc68 WD |
71 | BUG FIXES: |
72 | ||
c3046816 WD |
73 | - When -x (--one-file-system) is combined with -L (--copy-links) or |
74 | --copy-unsafe-links, no symlinked files are skipped, even if the | |
75 | referent file is on a different filesystem. | |
6609a9f1 | 76 | |
c3046816 WD |
77 | - The --link-dest code now works properly for a non-root user when |
78 | (1) the UIDs of the source and destination differ and -o was | |
79 | specified, or (2) when the group of the source can't be used on | |
80 | the destination and -g was specified. | |
823edc68 | 81 | |
c3046816 WD |
82 | - Fixed a bug in the handling of -H (hard-links) that might cause |
83 | the expanded PATH/NAME value of the current item to get | |
84 | overwritten (due to an expanded-name caching bug). | |
823edc68 | 85 | |
c3046816 WD |
86 | - We now reset the "new data has been sent" flag at the start of |
87 | each file we send. This makes sure that an interrupted transfer | |
88 | with the --partial option set doesn't keep a shorter temp file | |
89 | than the current basis file when no new data has been transfered | |
90 | over the wire for that file. | |
91 | ||
92 | - Fixed a byte-order problem in --batch-mode on big-endian machines. | |
93 | (Jay Fenlason) | |
94 | ||
c3046816 WD |
95 | - When using --cvs-exclude, the exclude items we get from a |
96 | per-directory's .cvsignore file once again only affect that one | |
97 | directory (not all following directories too). The items are also | |
98 | now properly word-split and parsed without any +/- prefix parsing. | |
99 | ||
100 | - When specifying the USER@HOST: prefix for a file, the USER part | |
101 | can now contain an '@', if needed (i.e. the last '@' is used to | |
102 | find the HOST, not the first). | |
103 | ||
104 | - Fixed some bugs in the handling of group IDs for non-root users: | |
105 | (1) It properly handles a group that the sender didn't have a name | |
106 | for (it would previously skip changing the group on any files in | |
107 | that group). (2) If --numeric-ids is used, rsync no longer | |
108 | attempts to set groups that the user doesn't have the permission | |
109 | to set. | |
110 | ||
111 | - Fixed the "refuse options" setting in the rsyncd.conf file. | |
112 | ||
113 | - Improved the -x (--one-file-system) flag's handling of any mount- | |
114 | point directories we encounter. It is both more optimal (in that | |
115 | it no longer does a useless scan of the contents of the mount- | |
116 | point dirs) and also fixes a bug where a remapped mount of the | |
117 | original filesystem could get discovered in a subdir we should be | |
118 | ignoring. | |
119 | ||
120 | - Rsync no longer discards a double-slash at the start of a filename | |
89afe532 | 121 | when trying to open the file. It also no longer constructs names |
b3bc3110 | 122 | that start with a double slash (unless the user supplied them). |
89afe532 | 123 | |
c3046816 | 124 | - Path-specifying options to a daemon should now work the same with |
de31639f WD |
125 | or without chroot turned on. Previously, such a option (such as |
126 | --link-dest) would get its absolute path munged into a relative | |
127 | one if chroot was not on, making that setting fairly useless. | |
128 | Rsync now transforms the path into one that is based on the | |
129 | module's base dir when chroot is not enabled. | |
8b463409 | 130 | |
c3046816 | 131 | - Fixed a compatibility problem interacting with older rsync |
8b463409 WD |
132 | versions that might send us an empty --suffix value without |
133 | telling us that --backup-dir was specified. | |
b1ad6a32 | 134 | |
c3046816 WD |
135 | - The "hosts allow" option for a daemon-over-remote-shell process |
136 | now has improved support for IPv6 addresses and a fix for systems | |
137 | that have a length field in their socket structs. | |
b1ad6a32 | 138 | |
c3046816 WD |
139 | - Fixed the ability to request an empty backup --suffix when sending |
140 | files to an rsync daemon. | |

142 | INTERNAL: |
143 | ||
c3046816 WD |
144 | - Most of the I/O is now buffered, which results in a pretty large |
145 | speedup when running under MS Windows. (Craig Barratt) | |
823edc68 | 146 | |
c3046816 WD |
147 | - Optimizations to the name-handling/comparing code have made some |
148 | significant reductions in user-CPU time for large file sets. | |
823edc68 | 149 | |
c3046816 | 150 | - Some cleanup of the variable types make the code more consistent. |
31e7451a | 151 | |
c3046816 | 152 | - Reduced memory requirements of hard link preservation. |
0a007489 | 153 | (J.W. Schultz) |
279b1c1e | 154 | |
c3046816 WD |
155 | - Implemented a new algorithm for hard-link handling that speeds up |
156 | the code significantly. (J.W. Schultz and Wayne Davison) | |
f8ebdf92 | 157 | |
c3046816 | 158 | - The --hard-link option now uses the first existing file in the |
64f21c31 WD |
159 | group of linked files as the basis for the transfer. This |
160 | prevents the sub-optimal transfer of a file's data when a new | |
161 | hardlink is added on the sending side and it sorts alphabetically | |
162 | earlier in the list than the files that are already present on the | |
163 | receiving side. | |
164 | ||
c3046816 WD |
165 | - Dropped support for protocol versions less than 20 (2.3.0 released |
166 | 15 Mar 1999) and activated warnings for protocols less than 25 | |
167 | (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz, | |
168 | severally) | |
aa953c32 | 169 | |
c3046816 | 170 | - More optimal data transmission for --hard-links (protocol 28). |
1a62c49d | 171 | |
c3046816 | 172 | - More optimal data transmission for --checksum (protocol 28). |
1a62c49d | 173 | |
c3046816 | 174 | - Less memory is used when --checksum is specified. |
1a62c49d | 175 | |
c3046816 | 176 | - Less memory is used in the file list (a per-file savings). |
0a007489 | 177 | |
c3046816 | 178 | - The generator is now better about not modifying the file list |
b2181306 WD |
179 | during the transfer in order to avoid a copy-on-write memory |
180 | bifurcation (on systems where fork() uses shared memory). | |
181 | Previously, rsync's shared memory would slowly become unshared, | |
182 | resulting in real memory usage nearly doubling on the receiving | |
183 | side by the end of the transfer. Now, as long as permissions | |
184 | are being preserved, the shared memory should remain that way | |
185 | for the entire transfer. | |
186 | ||
c3046816 WD |
187 | - Changed hardlink info and file_struct + strings to use allocation |
188 | pools. This reduces memory use for large file-sets and permits | |
189 | freeing memory to the OS. (J.W. Schultz) | |
b0a93231 | 190 | |
c3046816 WD |
191 | - The 2 pipes used between the receiver and generator processes |
192 | (which are forked on the same machine) were reduced to 1 pipe and | |
193 | the protocol improved so that (1) it is now impossible to have the | |
194 | "redo" pipe fill up and hang rsync, and (2) trailing messages from | |
195 | the receiver don't get lost on their way through the generator | |
196 | over to the sender (which mainly affected hard-link messages and | |
197 | verbose --stats output). | |
442743b8 | 198 | |
c3046816 WD |
199 | - Improved the internal uid/gid code to be more portable and a |
200 | little more optimized. | |
79d40530 | 201 | |
c3046816 | 202 | - The device numbers sent when using --devices are now sent as |
d008bcb5 WD |
203 | separate major/minor values with 32-bit accuracy (protocol 28). |
204 | Previously, the copied devices were sent as a single 32-bit | |
205 | number. This will make inter-operation of 64-bit binaries more | |
c3046816 WD |
206 | compatible with their 32-bit brethren (with both ends of the |
207 | connection are using protocol 28). Note that optimizations in the | |
208 | binary protocol for sending the device numbers often results in | |
209 | fewer bytes being used than before, even though more precision is | |
210 | now available. | |
211 | ||
212 | - Some cleanup of the exclude/include structures and its code made | |
213 | things clearer (internally), simpler, and more efficient. | |
214 | ||
215 | - The reading & writing of the file-list in batch-mode is now | |
216 | handled by the same code that sends & receives the list over the | |
217 | wire. This makes it much easier to maintain. (Note that the | |
218 | batch code is still considered to be experimental.) | |

219 | |
220 | BUILD CHANGES: | |
221 | ||
222 | - The configure script now accepts --with-rsyncd-conf=PATH to | |
223 | override the default value of the /etc/rsyncd.conf file. | |
224 | ||
225 | - Fixed configure bug when running "./configure --disable-ipv6". | |
226 | ||
227 | - Fixed compilation problem on Tru64 Unix (having to do with | |
228 | sockaddr.sa_len and sockaddr.sin_len). | |
229 | ||
230 | DEVELOPER RELATED: | |
231 | ||
232 | - Fixed "make test" bug when build dir is not the source dir. | |
233 | ||
234 | - Added a couple extra diffs in the "patches" dir, removed the ones | |
235 | that got applied, and rebuilt the rest. | |
