| 1 | NEWS for rsync 2.6.3 (UNRELEASED) |
| 2 | Protocol: 28 (unchanged) |
| 3 | Changes since 2.6.2: |
| 4 | |
| 5 | OUTPUT CHANGES (ATTN: those using a script to parse the verbose output): |
| 6 | |
| 7 | - Please note that the 2-line footer (output when verbose) now uses the |
| 8 | term "sent" instead of "wrote" and "received" instead of "read". If |
| 9 | you are not parsing the numeric values out of this footer, a script |
| 10 | should be better off using the empty line prior to the footer as the |
| 11 | indicator that the verbose output is over. |
| 12 | |
| 13 | - The output from the --stats option was similarly affected to change |
| 14 | "written" to "sent" and "read" to "received". |
| 15 | |
| 16 | - Made sure that a filename that contains a newline gets mentioned with |
| 17 | each newline transformed into a question mark (which makes sure that |
| 18 | a filename can't span multiple lines nor cause an empty line to be |
| 19 | output). |
| 20 | |
| 21 | BUG FIXES: |
| 22 | |
| 23 | - Fixed a crash bug that might appear when --delete was used and |
| 24 | multiple source directories were specified. |
| 25 | |
| 26 | - Fixed the 32-bit truncation of the file length when generating the |
| 27 | checksums. |
| 28 | |
| 29 | - The --backup code no longer attempts to create some directories |
| 30 | over and over again (generating warnings along the way). |
| 31 | |
| 32 | - Fixed a bug in the reading of the secrets file (by the daemon) and |
| 33 | the password file (by the client): the files no longer need to be |
| 34 | terminated by a newline for their content to be read in. |
| 35 | |
| 36 | - If a file has a read error on the sending side or the reconstructed |
| 37 | data doesn't match the expected checksum (perhaps due to the basis |
| 38 | file changing during the transfer), the receiver will no longer |
| 39 | retain the resulting file unless the --partial option was specified. |
| 40 | (Note: for the read-error detection to work, neither side can be |
| 41 | older than 2.6.3 -- older receivers will always retain the file, and |
| 42 | older senders don't tell the receiver that the file had a read |
| 43 | error.) |
| 44 | |
| 45 | - If a file gets resent in a single transfer and the --backup option |
| 46 | is enabled, rsync no longer performs a duplicate backup (losing the |
| 47 | original file in the process). |
| 48 | |
| 49 | - Fixed an age-old crash problem with --read-batch on a local copy |
| 50 | (rsync was improperly assuming --whole-file for the local copy). |
| 51 | |
| 52 | - Files specified in the daemon's "exclude" or "exclude from" config |
| 53 | items are now excluded from being uploaded (assuming that the module |
| 54 | allows uploading at all) in addition to the old download exclusion. |
| 55 | |
| 56 | - Got rid of a potential hang in the receiver when near the end of a |
| 57 | phase. |
| 58 | |
| 59 | - When using --backup without a --backup-dir, rsync no longer preserves |
| 60 | the modify time on directories. This avoids confusing NFS. |
| 61 | |
| 62 | - When --copy-links (-L) is specified, we now output a separate error |
| 63 | for a symlink that has no referent instead of claiming that a file |
| 64 | "vanished". |
| 65 | |
| 66 | - The --copy-links (-L) option no longer has the side-effect of telling |
| 67 | the receiving side to follow symlinks. See the --keep-dirlinks |
| 68 | option (mentioned below) for a way to specify that behavior. |
| 69 | |
| 70 | - Error messages from the daemon server's option-parsing (such as |
| 71 | refused options) now get sent back to the client (the server used |
| 72 | to just exit because the socket wasn't in the right state to send |
| 73 | the message). |
| 74 | |
| 75 | - Most errors that occur during a daemon transfer are now returned to |
| 76 | the user in addition to being logged (some messages are intended to |
| 77 | be daemon-only). |
| 78 | |
| 79 | - Fixed a bug in the daemon authentication code when using one of the |
| 80 | batch-processing options. |
| 81 | |
| 82 | - We try to work around some buggy IPv6 implementations that fail to |
| 83 | implement IPV6_V6ONLY. This should fix the "address in use" error |
| 84 | that some daemons get when running on an OS with a buggy IPv6 |
| 85 | implementation. Also, if the new code gets this error, we might |
| 86 | suggest that the user specify --ipv4 or --ipv6 (if we think it will |
| 87 | help). |
| 88 | |
| 89 | - When the remote rsync dies, make a better effort to recover any error |
| 90 | messages it may have sent before dying (the local rsync used to just |
| 91 | die with a socket-write error). |
| 92 | |
| 93 | - When using --delete and a --backup-dir that contains files that are |
| 94 | hard-linked to their destination equivalents, rsync now makes sure |
| 95 | that removed files really get removed (works around a really weird |
| 96 | rename() behavior). |
| 97 | |
| 98 | - Avoid a bogus run-time complaint about a lack of 64-bit integers when |
| 99 | the int64 type is defined as an off_t and it actually has 64-bits. |
| 100 | |
| 101 | - Added a configure check for open64() without mkstemp64() so that we |
| 102 | can avoid using mkstemp() when such a combination is encountered. |
| 103 | This bypasses a problem writing out large temp files on OSes such as |
| 104 | AIX and HP-UX. |
| 105 | |
| 106 | ENHANCEMENTS: |
| 107 | |
| 108 | - Added the --partial-dir=DIR option that lets you specify where to |
| 109 | (temporarily) put a partially transferred file (instead of over- |
| 110 | writing the destination file). E.g. --partial-dir=.rsync-partial |
| 111 | |
| 112 | - Added --keep-dirlinks (-K), which allows you to symlink a directory |
| 113 | onto another partition on the receiving side and have rsync treat it |
| 114 | as matching a normal directory from the sender. |
| 115 | |
| 116 | - Added the --inplace option that tells rsync to write each destination |
| 117 | file without using a temporary file. The matching of existing data |
| 118 | in the destination file can be severely limited by this, but there |
| 119 | are also cases where this is more efficient (such as appending data). |
| 120 | Use only when needed (see the man page for more details). |
| 121 | |
| 122 | - Added the "write only" option for the daemon's config file. |
| 123 | |
| 124 | - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) |
| 125 | and documented all these options in the man page. |
| 126 | |
| 127 | - Improved the handling of the --bwlimit option so that it's less |
| 128 | bursty, more accurate, and works properly over a larger range of |
| 129 | values. |
| 130 | |
| 131 | - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and |
| 132 | SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address. |
| 133 | |
| 134 | - Added the --checksum-seed=N option for advanced users. |
| 135 | |
| 136 | - Batch writing/reading has a brand-new implementation that is simpler, |
| 137 | fixes a few weird problems with the old code (such as no longer |
| 138 | sprinkling the batch files into different dirs or even onto different |
| 139 | systems), and is much less intrusive into the code (making it easier |
| 140 | to maintain for the future). The new code generates just one data |
| 141 | file instead of three, which makes it possible to read the batch via |
| 142 | stdin. Also, the old requirement of using the same fixed checksum- |
| 143 | seed for all batch processing has been removed. |
| 144 | |
| 145 | - If an rsync daemon has a module set with "list = no" (which hides its |
| 146 | presence in the list of available modules), a user that fails to |
| 147 | authenticate gets the same "unknown module" error that they would get |
| 148 | if the module were actually unknown (while still logging the real |
| 149 | error to the daemon's log file). This prevents fishing for module |
| 150 | names. |
| 151 | |
| 152 | - The daemon's "refuse options" config item now allows you to match |
| 153 | option names using wildcards and/or the single-letter option names. |
| 154 | |
| 155 | INTERNAL: |
| 156 | |
| 157 | - Some cleanup in the exclude code has saved some per-exclude memory |
| 158 | and made the code easier to maintain. |
| 159 | |
| 160 | - Improved the argv-overflow checking for a remote command that has |
| 161 | a lot of args. |
| 162 | |
| 163 | - Use rsyserr() in the various places that were still calling |
| 164 | rprintf() with strerror() as an arg. |
| 165 | |
| 166 | - If an rsync daemon is listening on multiple sockets (to handle both |
| 167 | IPv4 and IPv6 to a single port), we now close all the unneeded file |
| 168 | handles after we accept a connection (we used to close just one of |
| 169 | them). |
| 170 | |
| 171 | - Optimized the handling of larger block sizes (rsync used to slow to |
| 172 | a crawl if the block size got too large). Also cap the block size. |
| 173 | |
| 174 | - Optimized away a loop in hash_search(). |
| 175 | |
| 176 | BUILD CHANGES: |
| 177 | |
| 178 | - Added a "gen" target to rebuild most of the generated files, |
| 179 | including configure, config.h.in, the man pages, and proto.h. |
| 180 | |
| 181 | - If "make proto" doesn't find some changes in the prototypes, the |
| 182 | proto.h file is left untouched (its time-stamp used to always be |
| 183 | updated). |
| 184 | |
| 185 | - The variable $STRIP (that is optionally set by the install-strip |
| 186 | target's rule) was changed to $INSTALL_STRIP because some systems |
| 187 | have $STRIP set in the environment. |
| 188 | |
| 189 | - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. |
| 190 | |
| 191 | DEVELOPER RELATED: |
| 192 | |
| 193 | - The scripts in the testsuite dir were cleaned up a bit. |
| 194 | |
| 195 | - Some new diffs were added to the patches dir, and some accepted |
| 196 | ones were removed. |
| 197 | |
