1.1.1.2 ! misho 1: NEWS for rsync 3.1.0 (28 Sep 2013)
! 2: Protocol: 31 (changed)
! 3: Changes since 3.0.9:
! 4:
! 5: OUTPUT CHANGES:
! 6:
! 7: - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the
! 8: --human-readable option for a way to turn it off. See also the daemon's
! 9: "log format" parameter and related command-line options (including
! 10: --out-format) for a modifier that can be used to request digit-grouping
! 11: or human-readable output in log escapes. (Note that log output is
! 12: unchanged by default.)
! 13:
! 14: - The --list-only option is now affected by the --human-readable setting.
! 15: It will display digit groupings by default, and unit suffixes if higher
! 16: levels of readability are requested. Also, the column width for the size
! 17: output has increased from 11 to 14 characters when human readability is
! 18: enabled. Use --no-h to get the old-style output and column size.
! 19:
! 20: - The output of the --progress option has changed: the string "xfer" was
! 21: shortened to "xfr", and the string "to-check" was shortened to "to-chk",
! 22: both designed to make room for the (by default) wider display of file
! 23: size numbers without making the total line-length longer. Also, when
! 24: incremental recursion is enabled, the string "ir-chk" will be used
! 25: instead of "to-chk" up until the incremental-recursion scan is done,
! 26: letting you know that the value to check and the total value will still
! 27: be increasing as new files are found.
! 28:
! 29: - Enhanced the --stats output: 1) to mention how many files were created
! 30: (protocol >= 28), 2) to mention how many files were deleted (a new line
! 31: for protocol 31, but only output when --delete is in effect), and 3) to
! 32: follow the file-count, created-count, and deleted-count with a subcount
! 33: list that shows the counts by type. The wording of the transferred count
! 34: has also changed so that it is clearer that it is only a count of regular
! 35: files.
1.1 misho 36:
37: BUG FIXES:
38:
1.1.1.2 ! misho 39: - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a
! 40: full output buffer.
1.1 misho 41:
1.1.1.2 ! misho 42: - Fixed some rare bugs in --iconv processing that might cause a multibyte
! 43: character to get translated incorrectly.
1.1 misho 44:
1.1.1.2 ! misho 45: - Fixed a bogus "vanished file" error if some files were specified with
! 46: "./" prefixes and others were not.
1.1 misho 47:
1.1.1.2 ! misho 48: - Fixed a bug in --sparse where an extra gap could get inserted after a
! 49: partial write.
1.1 misho 50:
1.1.1.2 ! misho 51: - Changed the way --progress overwrites its prior output in order to make
! 52: it nearly impossible for the progress to get overwritten by an error.
1.1 misho 53:
1.1.1.2 ! misho 54: - Improved the propagation of abnormal-exit error messages. This should
! 55: help the client side to receive errors from the server when it is exiting
! 56: abnormally, and should also avoid dying with an "connection unexpectedly
! 57: closed" exit when the closed connection is really expected.
1.1 misho 58:
1.1.1.2 ! misho 59: - The sender now checks each file it plans to remove to ensure that it
! 60: hasn't changed from the first stat's info. This helps to avoid losing
! 61: file data when the user is not using the option in a safe manner.
1.1 misho 62:
1.1.1.2 ! misho 63: - Fixed a data-duplication bug in the compress option that made compression
! 64: less efficient. This improves protocol 31 onward, while behaving in a
! 65: compatible (buggy) manner with older rsync protocols.
1.1 misho 66:
1.1.1.2 ! misho 67: - When creating a temp-file, rsync is now a bit smarter about it dot-char
! 68: choices, which can fix a problem on OS X with names that start with "..".
1.1 misho 69:
1.1.1.2 ! misho 70: - Rsync now sets a cleanup flag for --inplace and --append transfers that
! 71: will flush the write buffer if the transfer aborts. This ensures that
! 72: more received data gets written out to the disk on an aborted transfer
! 73: (which is quite helpful on a slow, flaky connection).
1.1 misho 74:
1.1.1.2 ! misho 75: - The reads that map_ptr() now does are aligned on 1K boundaries. This
! 76: helps some filesystems and/or files that don't like unaligned reads.
1.1 misho 77:
1.1.1.2 ! misho 78: - Fix an issue in the msleep() function if time jumps backwards.
1.1 misho 79:
1.1.1.2 ! misho 80: - Fix daemon-server module-name splitting bug where an arg would get split
! 81: even if --protect-args was used.
1.1 misho 82:
1.1.1.2 ! misho 83: ENHANCEMENTS:
1.1 misho 84:
1.1.1.2 ! misho 85: - Added the --remote-option=OPT (-M OPT) command-line option that is useful
! 86: for things like sending a remote --log-file=FILE or --fake-super option.
1.1 misho 87:
1.1.1.2 ! misho 88: - Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained
! 89: control over what is output. Added an extra type of --progress output
! 90: using --info=progress2.
1.1 misho 91:
1.1.1.2 ! misho 92: - The --msgs2stderr option can help with debugging rsync by allowing the
! 93: debug messages to get output to stderr rather than travel via the socket
! 94: protocol.
1.1 misho 95:
1.1.1.2 ! misho 96: - Added the --delete-missing-args and --ignore-missing-args options to
! 97: either delete or ignore user-specified files on the receiver that are
! 98: missing on the sender (normally the absence of user-specified files
! 99: generates an error).
1.1 misho 100:
1.1.1.2 ! misho 101: - Added a "T" (terabyte) category to the --human-readable size suffixes.
1.1 misho 102:
1.1.1.2 ! misho 103: - Added the --usermap/--groupmap/--chown options for manipulating file
! 104: ownership during the copy.
1.1 misho 105:
1.1.1.2 ! misho 106: - Added the "%C" escape to the log-output handling, which will output the
! 107: MD5 checksum of any transferred file, or all files if --checksum was
! 108: specified (when protocol 30 or above is in effect).
1.1 misho 109:
1.1.1.2 ! misho 110: - Added the "reverse lookup" parameter to the rsync daemon config file to
! 111: allow reverse-DNS lookups to be disabled.
! 112:
! 113: - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can
! 114: be disabled via "forward lookup" parameter (defaults to enabled).
! 115:
! 116: - Added a way for more than one group to be specified in the daemon's
! 117: config file, including a way to specify that you want all of the
! 118: specified user's groups without having to name them. Also changed the
! 119: daemon to complain about an inability to set explicitly-specified uid/gid
! 120: values, even when not run by a super-user.
! 121:
! 122: - The daemon now tries to send the user the error messages from the
! 123: pre-xfer exec script when it fails.
! 124:
! 125: - Improved the use of alt-dest options into an existing hierarchy of files:
! 126: If a match is found in an alt-dir, it takes precedence over an existing
! 127: file. (We'll need to wait for a future version before attribute-changes
! 128: on otherwise unchanged files are safe when using an existing hierarchy.)
! 129:
! 130: - Added per-user authorization options and group-authorization support to
! 131: the daemon's "auth users" parameter.
! 132:
! 133: - Added a way to reference environment variables in a daemon's config file
! 134: (using %VAR% references).
! 135:
! 136: - When replacing a non-dir with a symlink/hard-link/device/special-file,
! 137: the update should now be done in an atomic manner.
! 138:
! 139: - Avoid re-sending xattr info for hard-linked files w/the same xattrs
! 140: (protocol 31).
! 141:
! 142: - The backup code was improved to use better logic maintaining the backup
! 143: directory hierarchy. Also, when a file is being backed up, rsync tries
! 144: to hard-link it into place so that the upcoming replacement of the
! 145: destination file will be atomic (for the normal, non-inplace logic).
! 146:
! 147: - Added the ability to synchronize nano-second modified times.
! 148:
! 149: - Added a few more default suffixes for the "dont compress" settings.
! 150:
! 151: - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow
! 152: the default for the --protect-args command-line option to be overridden.
! 153:
! 154: - Added the --preallocate command-line option.
! 155:
! 156: - Allow --password-file=- to read the password from stdin (filename "-").
! 157:
! 158: - Rsync now comes packaged with an rsync-ssl helper script that can be
! 159: used to contact a remote rsync daemon using a piped-stunnel command.
! 160: It also includes an stunnel config file to run the server side to
! 161: support ssl daemon connections. See the packaging/lsb/rsync.spec
! 162: file for one way to package the resulting files. (Suggestions for
! 163: how to make this even easier to install & use are welcomed.)
! 164:
! 165: - Improved the speed of some --inplace updates when there are lots of
! 166: identical checksum blocks that end up being unusable.
! 167:
! 168: - Added the --outbuf=N|L|B option for choosing the output buffering.
! 169:
! 170: - Repeating the --fuzzy option now causes the code to look for fuzzy
! 171: matches inside alt-dest directories too.
! 172:
! 173: - The --chmod option now supports numeric modes, e.g. --chmod=644,D755
! 174:
! 175: - Added some Solaris xattr code.
! 176:
! 177: - Made an rsync daemon (the listening process) exit with a 0 status when
! 178: it was signaled to die. This helps launchd.
! 179:
! 180: - Improved the RSYNC_* environment variables for the pre-xfer exec script:
! 181: when a daemon is sent multiple request args, they are now joined into a
! 182: single return value (separated by spaces) so that the RSYNC_REQUEST
! 183: environment variable is accurate for any "pre-xfer exec". The values in
! 184: RSYNC_ARG# vars are no longer truncated at the "." arg (prior to the
! 185: request dirs/files), so that all the requested values are also listed
! 186: (separately) in RSYNC_ARG# variables.
! 187:
! 188: EXTRAS:
! 189:
! 190: - Added an "instant-rsyncd" script to the support directory, which makes
! 191: it easy to configure a simple rsync daemon in the current directory.
! 192:
! 193: - Added the "mapfrom" and "mapto" scripts to the support directory, which
! 194: makes it easier to do user/group mapping in a local transfer based on
! 195: passwd/group files from another machine.
! 196:
! 197: - There's a new, improved version of the lsh script in the support dir:
! 198: it's written in perl and supports -u without resorting to using sudo
! 199: (when run as root). The old shell version is now named lsh.sh.
! 200:
! 201: - There is a helper script named rsync-slash-strip in the support directory
! 202: for anyone that wants to change the way rsync handles args with trailing
! 203: slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into
! 204: arg/).
! 205:
! 206: INTERNAL:
! 207:
! 208: - The I/O code was rewritten to be simpler and do bigger buffered reads
! 209: over the socket. The I/O between the receiver and the generator was
! 210: changed to be standard multiplexed-I/O (like that over the socket).
! 211:
! 212: - The sender tries to use any dead time while the generator is looking for
! 213: files to transfer in order to do sender-side directory scanning in a more
! 214: parallel manner.
! 215:
! 216: - A daemon can now inform a client about a daemon-configured timeout value
! 217: so that the client can assist in the keep-alive activity (protocol 31).
! 218:
! 219: - The filter code received some refactoring to make it more extendible, to
! 220: read better, and do better sanity checking.
! 221:
! 222: - Really big numbers are now output using our own big-num routine rather
! 223: than casting them to a double and using a %.0f conversion.
! 224:
! 225: - The pool_alloc library has received some minor improvements in alignment
! 226: handling.
! 227:
! 228: - Added init_stat_x() function to avoid duplication of acl/xattr init code.
! 229:
! 230: - The included zlib was upgraded from 1.2.3 to 1.2.8.
! 231:
! 232: - Rsync can now be compiled to use an unmodified zlib library instead of
! 233: the tweaked one that is included with rsync. This will eventually
! 234: become the default, at which point we'll start the countdown to removing
! 235: the included zlib. Until then, feel free to configure using:
! 236:
! 237: ./configure --with-included-zlib=no
! 238:
! 239: DEVELOPER RELATED:
! 240:
! 241: - Added more conditional debug output.
! 242:
! 243: - Fixed some build issues for android and minix.
