| 1 | NEWS for rsync 2.6.1 (UNRELEASED) |
| 2 | Protocol: 27 (unchanged) |
| 3 | Changes since 2.6.0: |
| 4 | |
| 5 | ENHANCEMENTS: |
| 6 | |
| 7 | * Lower memory use and more optimal transfer of data over |
| 8 | the socket (see the INTERNAL section for details). |
| 9 | |
| 10 | * The RSYNC_PROXY environment variable can now contain a |
| 11 | "USER:PASS@" prefix before the "HOST:PORT" information. |
| 12 | (Bardur Arantsson) |
| 13 | |
| 14 | * The --progress output now mentions how far along in the |
| 15 | transfer we are, including both a count of files transferred |
| 16 | and a percentage of the total file-count that we're processed. |
| 17 | It was also improved to better show the current rate of |
| 18 | transfer and the estimated time left. |
| 19 | |
| 20 | * The configure script now accepts --with-rsyncd-conf=PATH |
| 21 | to override the default value of the /etc/rsyncd.conf file. |
| 22 | |
| 23 | BUG FIXES: |
| 24 | |
| 25 | * When -x (--one-file-system) is combined with -L (--copy-links) |
| 26 | or --copy-unsafe-links, no symlinked files are skipped, even |
| 27 | if the referant file is on a different filesystem. |
| 28 | |
| 29 | * The --link-dest code now works properly for a non-root user |
| 30 | when the UIDs of the source and destination differ and -o was |
| 31 | specified, and when the group of the source can't be used on |
| 32 | the destination and -g was specified. (Wayne Davison) |
| 33 | |
| 34 | * Fixed a bug in the handling of -H (hard-links) that might |
| 35 | cause the expanded PATH/NAME value of the current item to |
| 36 | get overwritten (due to an expanded-name caching bug). |
| 37 | (Wayne Davison) |
| 38 | |
| 39 | * We now reset the "new data has been sent" flag at the start |
| 40 | of each file we send. This makes sure that an interrupted |
| 41 | transfer with the --partial option set doesn't keep a shorter |
| 42 | temp file than the current basis file when no new data has been |
| 43 | transfered over the wire for that file. (Wayne Davison) |
| 44 | |
| 45 | * Fixed a byte-order problem in --batch-mode on big-endian |
| 46 | machines. (Jay Fenlason) |
| 47 | |
| 48 | * Fixed configure bug when running "./configure --disable-ipv6". |
| 49 | (Wayne Davison) |
| 50 | |
| 51 | * Fixed "make test" bug when build dir is not the source dir. |
| 52 | |
| 53 | * When using --cvs-exclude, the exclude items we get from a |
| 54 | directory's .cvsignore file once again only affect that one |
| 55 | directory (and not all following directories too). |
| 56 | |
| 57 | * When transferring a file that has group 0 with -g specified |
| 58 | (typically via -a) and not enough privs to retain the group, |
| 59 | rsync no longer complains about "chown" failing. |
| 60 | |
| 61 | * When specifying the USER@HOST: prefix for a file, the USER |
| 62 | part can now contain an '@', if needed (i.e. the last '@' |
| 63 | is used to find the HOST, not the first). |
| 64 | |
| 65 | * Fixed some bugs in the handling of group IDs for non-root |
| 66 | users: (1) It properly handles a group that the sender didn't |
| 67 | have a name for (it would previously skip changing the group |
| 68 | on any files in that group). (2) If --numeric-ids is used, |
| 69 | rsync no longer attempts to set groups that the user doesn't |
| 70 | have the permission to set. |
| 71 | |
| 72 | * Fixed the "refuse options" setting in the rsyncd.conf file. |
| 73 | |
| 74 | * Rsync no longer discards a double-slash at the start of a filename |
| 75 | when trying to open the file. It also no longer constructs names |
| 76 | that start with a double slash (unless the user supplied both). |
| 77 | |
| 78 | * Fixed compilation problem on Tru64 Unix (having to do with |
| 79 | sockaddr.sa_len and sockaddr.sin_len). |
| 80 | |
| 81 | INTERNAL: |
| 82 | |
| 83 | * Most of the I/O is now buffered, which results in a pretty |
| 84 | large speedup when running under MS Windows. (Craig Barratt) |
| 85 | |
| 86 | * Optimizations to the name-handling/comparing code have made |
| 87 | some significant reductions in user-CPU time for large file |
| 88 | sets. (Wayne Davison) |
| 89 | |
| 90 | * Some variable-type cleanup that makes the code more consistent. |
| 91 | (Wayne Davison) |
| 92 | |
| 93 | * Reduced memory requirements of hard link preservation. |
| 94 | (J.W. Schultz) |
| 95 | |
| 96 | * Implemented a new algorithm for hard-link handling that speeds |
| 97 | up the code significantly. (J.W. Schultz and Wayne Davison) |
| 98 | |
| 99 | * The --hard-link option now uses the first existing file in the |
| 100 | group of linked files as the basis for the transfer. This |
| 101 | prevents the sub-optimal transfer of a file's data when a new |
| 102 | hardlink is added on the sending side and it sorts alphabetically |
| 103 | earlier in the list than the files that are already present on the |
| 104 | receiving side. |
| 105 | |
| 106 | * Dropped support for protocol versions less than 20 |
| 107 | (2.3.0 released 15 Mar 1999) and activated warnings for |
| 108 | protocols less than 25 (2.5.0 released 23 Aug 2001) |
| 109 | (Wayne Davison and J.W. Schultz, severally) |
| 110 | |
| 111 | * More optimal data transmission for --hard-links (protocol 28). |
| 112 | |
| 113 | * More optimal data transmission for --checksum (protocol 28). |
| 114 | |
| 115 | * Less memory is used when --checksum is specified. |
| 116 | |
| 117 | * Less memory is used in the file list (a per-file savings). |
| 118 | |
| 119 | * Changed hardlink info and file_struct + strings to use |
| 120 | allocation pools. This reduces memory use for large |
| 121 | filesets and permits freeing memory to the OS. (J.W. Schultz) |
| 122 | |
| 123 | * The 2 pipes used between the receiver and generator processes |
| 124 | (which are forked on the same machine) were reduced to 1 pipe |
| 125 | and the protocol improved so that (1) it is now impossible to |
| 126 | have the "redo" pipe fill up and hang rsync, and (2) trailing |
| 127 | messages from the receiver don't get lost on their way through |
| 128 | the generator over to the sender (the latter mainly affected |
| 129 | hard-link messages). (Wayne Davison) |
| 130 | |
| 131 | * The reading & writing of the file list in batch-mode is now |
| 132 | handled by the same code that sends & receives the list over |
| 133 | the wire. This makes it much easier to maintain. |
| 134 | |
| 135 | * Optimized the -x (--one-file-system) flag's handling of any |
| 136 | mount-point directories we encounter (it no longer scans the |
| 137 | contents of the mount-point dirs, just to throw away the data). |
| 138 | |
| 139 | * Improved the internal uid/gid code to be more portable and |
| 140 | a little more optimized. |

| 143 | NEWS for rsync 2.6.0 (1 Jan 2004) |
| 144 | Protocol: 27 (changed) |
| 145 | Changes since 2.5.7: |
| 146 | |
| 147 | ENHANCEMENTS: |
| 148 | |
| 149 | * "ssh" is now the default remote shell for rsync. If you want to |
| 150 | change this, configure like this: "./configure --with-rsh=rsh". |
| 151 | |
| 152 | * Added --files-from, --no-relative, --no-implied-dirs, and --from0. |
| 153 | Note that --from0 affects the line-ending character for all the |
| 154 | files read by the --*-from options. (Wayne Davison) |
| 155 | |
| 156 | * Length of csum2 is now per-file starting with protocol version |
| 157 | 27. (J.W. Schultz) |
| 158 | |
| 159 | * Per-file dynamic block size is now sqrt(file length). The |
| 160 | per-file checksum size is determined according to an algorithm |
| 161 | provided by Donovan Baarda which reduces the probability of rsync |
| 162 | algorithm corrupting data and falling back using the whole md4 |
| 163 | checksums. (J.W. Schultz, Donovan Baarda) |
| 164 | |
| 165 | * The --stats option no longer includes the (debug) malloc summary |
| 166 | unless the verbose option was specified at least twice. |
| 167 | |
| 168 | * Added a new error/warning code for when files vanish from the |
| 169 | sending side. Made vanished source files not interfere with the |
| 170 | file-deletion pass when --delete-after was specified. |
| 171 | |
| 172 | * Various trailing-info sections are now preceded by a newline. |
| 173 | |
| 174 | BUG FIXES: |
| 175 | |
| 176 | * Fixed several exclude/include matching bugs when using wild-cards. |
| 177 | This has a several user-visible effects, all of which make the |
| 178 | matching more consistent and intuitive. This should hopefully not |
| 179 | cause anyone problems since it makes the matching work more like |
| 180 | what people are expecting. (Wayne Davison) |
| 181 | |
| 182 | - A pattern with a "**" no longer causes a "*" to match slashes. |
| 183 | For example, with "/*/foo/**", "foo" must be 2 levels deep. |
| 184 | [If your string has BOTH "*" and "**" wildcards, changing the |
| 185 | "*" wildcards to "**" will provide the old behavior in all |
| 186 | versions.] |
| 187 | |
| 188 | - "**/foo" now matches at the base of the transfer (like /foo |
| 189 | does). [Use "/**/foo" to get the old behavior in all versions.] |
| 190 | |
| 191 | - A non-anchored wildcard term floats to match beyond the base of |
| 192 | the transfer. E.g. "CVS/R*" matches at the end of the path, |
| 193 | just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*" |
| 194 | to get the old behavior in all versions.] |
| 195 | |
| 196 | - Including a "**" in the match term causes it to be matched |
| 197 | against the entire path, not just the name portion, even if |
| 198 | there aren't any interior slashes in the term. E.g. "foo**bar" |
| 199 | would exclude "/path/foo-bar" (just like before) as well as |
| 200 | "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the |
| 201 | old behavior in all versions.] |
| 202 | |
| 203 | * The exclude list specified in the daemon's config file is now |
| 204 | properly applied to the pulled items no matter how deep the |
| 205 | user's file-args are in the source tree. (Wayne Davison) |
| 206 | |
| 207 | * For protocol version >= 27, mdfour_tail() is called when the |
| 208 | block size (including checksum_seed) is a multiple of 64. |
| 209 | Previously it was not called, giving the wrong MD4 checksum. |
| 210 | (Craig Barratt) |
| 211 | |
| 212 | * For protocol version >= 27, a 64 bit bit counter is used in |
| 213 | mdfour.c as required by the RFC. Previously only a 32 bit bit |
| 214 | counter was used, causing incorrect MD4 file checksums for |
| 215 | file sizes >= 512MB - 4. (Craig Barratt) |
| 216 | |
| 217 | * Fixed a crash bug when interacting with older rsync versions and |
| 218 | multiple files of the same name are destined for the same dir. |
| 219 | (Wayne Davison) |
| 220 | |
| 221 | * Keep tmp names from overflowing MAXPATHLEN. |
| 222 | |
| 223 | * Make --link-dest honor the absence of -p, -o, and -g. |
| 224 | |
| 225 | * Made rsync treat a trailing slash in the destination in a more |
| 226 | consistent manner. |
| 227 | |
| 228 | * Fixed file I/O error detection. (John Van Essen) |
| 229 | |
| 230 | * Fixed bogus "malformed address {hostname}" message in rsyncd log |
| 231 | when checking IP address against hostnames from "hosts allow" |
| 232 | and "hosts deny" parameters in config file. |
| 233 | |
| 234 | * Print heap statistics when verbose >= 2 instead of when >= 1. |
| 235 | |
| 236 | * Fixed a compression (-z) bug when syncing a mostly-matching file |
| 237 | that contains already-compressed data. (Yasuoka Masahiko and |
| 238 | Wayne Davison) |
| 239 | |
| 240 | * Fixed a bug in the --backup code that could cause deleted files |
| 241 | to not get backed up. |
| 242 | |
| 243 | * When the backup code makes new directories, create them with mode |
| 244 | 0700 instead of 0755 (since the directory permissions in the |
| 245 | backup tree are not yet copied from the main tree). |
| 246 | |
| 247 | * Call setgroups() in a more portable manner. |
| 248 | |
| 249 | * Improved file-related error messages to better indicate exactly |
| 250 | what pathname failed. (Wayne Davison) |
| 251 | |
| 252 | * Fixed some bugs in the handling of --delete and --exclude when |
| 253 | using the --relative (-R) option. (Wayne Davison) |
| 254 | |
| 255 | * Fixed bug that prevented regular files from replacing |
| 256 | special files and caused a directory in --link-dest or |
| 257 | --compare-dest to block the creation of a file with the |
| 258 | same path. A directory still cannot be replaced by a |
| 259 | regular file unless --delete specified. (J.W. Schultz) |
| 260 | |
| 261 | * Detect and report when open or opendir succeed but read and |
| 262 | readdir fail caused by network filesystem issues and truncated |
| 263 | files. (David Norwood, Michael Brown, J.W. Schultz) |
| 264 | |
| 265 | * Added a fix that should give ssh time to restore the tty settings |
| 266 | if the user presses Ctrl-C at an ssh password prompt. |
| 267 | |
| 268 | INTERNAL: |
| 269 | |
| 270 | * Eliminated vestigial support for old versions that we stopped |
| 271 | supporting. (J.W. Schultz) |
| 272 | |
| 273 | * Simplified some of the option-parsing code. (Wayne Davison) |
| 274 | |
| 275 | * Some cleanup made to the exclude code, as well as some new |
| 276 | defines added to enhance readability. (Wayne Davison) |
| 277 | |
| 278 | * Changed the protocol-version code so that it can interact at a |
| 279 | lower protocol level than the maximum supported by both sides. |
| 280 | Added an undocumented option, --protocol=N, to force the value |
| 281 | we advertise to the other side (primarily for testing purposes). |
| 282 | (Wayne Davison) |
