| 1 | NEWS for rsync 2.6.2 (30 Apr 2004) |
| 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 |
| 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. |
| 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 | |
| 22 | BUILD CHANGES: |
| 23 | |
| 24 | - Got rid of the configure check for sys/sysctl.h (it wasn't used |
| 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. |
| 28 | |
| 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 | |
| 35 | DEVELOPER RELATED: |
| 36 | |
| 37 | - Improved the testsuite's "merge" test to work on OSF1. |
| 38 | |
| 39 | - Two new diffs were added to the patches dir. |

| 42 | NEWS for rsync 2.6.1 (26 Apr 2004) |
| 43 | Protocol: 28 (changed) |
| 44 | Changes since 2.6.0: |
| 45 | |
| 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 | |
| 53 | ENHANCEMENTS: |
| 54 | |
| 55 | - Lower memory use, more optimal transfer of data over the socket, |
| 56 | and lower CPU usage (see the INTERNAL section for details). |
| 57 | |
| 58 | - The RSYNC_PROXY environment variable can now contain a |
| 59 | "USER:PASS@" prefix before the "HOST:PORT" information. |
| 60 | (Bardur Arantsson) |
| 61 | |
| 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. |
| 67 | |
| 68 | - Documentation changes now attempt to describe some often mis- |
| 69 | understood features more clearly. |
| 70 | |
| 71 | BUG FIXES: |
| 72 | |
| 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. |
| 76 | |
| 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. |
| 81 | |
| 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). |
| 85 | |
| 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 | |
| 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 |
| 121 | when trying to open the file. It also no longer constructs names |
| 122 | that start with a double slash (unless the user supplied them). |
| 123 | |
| 124 | - Path-specifying options to a daemon should now work the same with |
| 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. |
| 130 | |
| 131 | - Fixed a compatibility problem interacting with older rsync |
| 132 | versions that might send us an empty --suffix value without |
| 133 | telling us that --backup-dir was specified. |
| 134 | |
| 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. |
| 138 | |
| 139 | - Fixed the ability to request an empty backup --suffix when sending |
| 140 | files to an rsync daemon. |
| 141 | |
| 142 | INTERNAL: |
| 143 | |
| 144 | - Most of the I/O is now buffered, which results in a pretty large |
| 145 | speedup when running under MS Windows. (Craig Barratt) |
| 146 | |
| 147 | - Optimizations to the name-handling/comparing code have made some |
| 148 | significant reductions in user-CPU time for large file sets. |
| 149 | |
| 150 | - Some cleanup of the variable types make the code more consistent. |
| 151 | |
| 152 | - Reduced memory requirements of hard link preservation. |
| 153 | (J.W. Schultz) |
| 154 | |
| 155 | - Implemented a new algorithm for hard-link handling that speeds up |
| 156 | the code significantly. (J.W. Schultz and Wayne Davison) |
| 157 | |
| 158 | - The --hard-link option now uses the first existing file in the |
| 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 | |
| 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) |
| 169 | |
| 170 | - More optimal data transmission for --hard-links (protocol 28). |
| 171 | |
| 172 | - More optimal data transmission for --checksum (protocol 28). |
| 173 | |
| 174 | - Less memory is used when --checksum is specified. |
| 175 | |
| 176 | - Less memory is used in the file list (a per-file savings). |
| 177 | |
| 178 | - The generator is now better about not modifying the file list |
| 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 | |
| 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) |
| 190 | |
| 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). |
| 198 | |
| 199 | - Improved the internal uid/gid code to be more portable and a |
| 200 | little more optimized. |
| 201 | |
| 202 | - The device numbers sent when using --devices are now sent as |
| 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 |
| 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. |
| 236 | |
