1 NEWS for rsync 3.1.0 (UNRELEASED)
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.)
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.
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.
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
39 - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a
42 - Fixed some rare bugs in --iconv processing that might cause a multibyte
43 character to get translated incorrectly.
45 - Fixed a bogus "vanished file" error if some files were specified with
46 "./" prefixes and others were not.
48 - Changed the way --progress overwrites its prior output in order to make
49 it nearly impossible for the progress to get overwritten by an error.
51 - Improved the propagation of abnormal-exit error messages. This should
52 help the client side to receive errors from the server when it is exiting
53 abnormally, and should also avoid dying with an "connection unexpectedly
54 closed" exit when the closed connection is really expected.
56 - The sender now checks each file it plans to remove to ensure that it
57 hasn't changed from the first stat's info. This helps to avoid losing
58 file data when the user is not using the option in a safe manner.
60 - Fixed a data-duplication bug in the compress option that made compression
61 less efficient. This improves protocol 31 onward, while behaving in a
62 compatible (buggy) manner with older rsync protocols.
64 - When creating a temp-file, rsync is now a bit smarter about it dot-char
65 choices, which can fix a problem on OS X with names that start with "..".
67 - The reads that map_ptr() now does are aligned on 1K boundaries. This
68 helps some filesystems and/or files that don't like unaligned reads.
70 - Fix an issue in the msleep() function if time jumps backwards.
72 - Fix daemon-server module-name splitting bug where an arg would get split
73 even if --protect-args was used.
77 - Added the --remote-option=OPT (-M OPT) command-line option that is useful
78 for things like sending a remote --log-file=FILE or --fake-super option.
80 - Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained
81 control over what is output. Added an extra type of --progress output
82 using --info=progress2.
84 - The --msgs2stderr option can help with debugging rsync by allowing the
85 debug messages to get output to stderr rather than travel via the socket
88 - Added the --delete-missing-args and --ignore-missing-args options to
89 either delete or ignore user-specified files on the receiver that are
90 missing on the sender (normally the absence of user-specified files
93 - Added a "T" (terabyte) category to the --human-readable size suffixes.
95 - Added the --usermap/--groupmap/--chown options for manipulating file
96 ownership during the copy.
98 - Added the "%C" escape to the log-output handling, which will output the
99 MD5 checksum of any transferred file, or all files if --checksum was
100 specified (when protocol 30 or above is in effect).
102 - Added the "reverse lookup" parameter to the rsync daemon config file to
103 allow reverse-DNS lookups to be disabled.
105 - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can
106 be disabled via "forward lookup" parameter (defaults to enabled).
108 - Added a way for more than one group to be specified in the daemon's
109 config file, including a way to specify that you want all of the
110 specified user's groups without having to name them. Also changed the
111 daemon to complain about an inability to set explicitly-specified uid/gid
112 values, even when not run by a super-user.
114 - The daemon now tries to send the user the error messages from the
115 pre-xfer exec script when it fails.
117 - Improved the use of alt-dest options into an existing hierarchy of files:
118 If a match is found in an alt-dir, it takes precedence over an existing
119 file. (We'll need to wait for a future version before attribute-changes
120 on otherwise unchanged files are safe when using an existing hierarchy.)
122 - Added per-user authorization options and group-authorization support to
123 the daemon's "auth users" parameter.
125 - Added a way to reference environment variables in a daemon's config file
126 (using %VAR% references).
128 - When replacing a non-dir with a symlink/hard-link/device/special-file,
129 the update should now be done in an atomic manner.
131 - Avoid re-sending xattr info for hard-linked files w/the same xattrs
134 - The backup code was improved to use better logic maintaining the backup
135 directory hierarchy. Also, when a file is being backed up, rsync tries
136 to hard-link it into place so that the upcoming replacement of the
137 destination file will be atomic (for the normal, non-inplace logic).
139 - Added the ability to synchronize nano-second modified times.
141 - Added a few more default suffixes for the "dont compress" settings.
143 - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow
144 the default for the --protect-args command-line option to be overridden.
146 - Added the --preallocate command-line option.
148 - Allow --password-file=- to read the password from stdin (filename "-").
150 - Rsync now comes packaged with an rsync-ssl helper script that can be
151 used to contact a remote rsync daemon using a piped-stunnel command.
152 It also includes an stunnel config file to run the server side to
153 support ssl daemon connections. See the packaging/lsb/rsync.spec
154 file for one way to package the resulting files. (Suggestions for
155 how to make this even easier to install & use are welcomed.)
157 - Improved the speed of some --inplace updates when there are lots of
158 identical checksum blocks that end up being unsuable.
160 - Added the --outbuf=N|L|B option for chosing the output buffering.
162 - Repating the --fuzzy option now causes the code to look for fuzzy matches
163 inside alt-dest directories too.
165 - The --chmod option now supports numeric modes, e.g. --chmod=644,D755
167 - Added some Solaris xattr code.
169 - Made an rsync daemon (the listening process) exit with a 0 status when
170 it was signalled to die. This helps launchd.
172 - Improved the RSYNC_* environment variables for the pre-xfer exec script:
173 when a daemon is sent multiple request args, they are now joined into a
174 single return value (separated by spaces) so that the RSYNC_REQUEST
175 environment variable is accurate for any "pre-xfer exec". The values in
176 RSYNC_ARG# vars are no longer truncated at the "." arg (prior to the
177 request dirs/files), so that all the requested values are also listed
178 (separately) in RSYNC_ARG# variables.
182 - Added an "instant-rsyncd" script to the support directory, which makes
183 it easy to configure a simple rsync daemon in the current directory.
185 - Added the "mapfrom" and "mapto" scripts to the support directory, which
186 makes it easier to do user/group mapping in a local transfer based on
187 passwd/group files from another machine.
189 - There's a new, improved version of the lsh script in the support dir:
190 it's written in perl and supports -u without resorting to using sudo
191 (when run as root). The old shell version is now named lsh.sh.
193 - There is a helper script named rsync-slash-strip in the support directory
194 for anyone that wants to change the way rsync handles args with trailing
195 slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into
200 - The I/O code was rewritten to be simpler and do bigger buffered reads
201 over the socket. The I/O between the receiver and the generator was
202 changed to be standard multiplexed-I/O (like that over the socket).
204 - The sender tries to use any dead time while the generator is looking for
205 files to transfer in order to do sender-side directory scanning in a more
208 - A daemon can now inform a client about a daemon-configured timeout value
209 so that the client can assist in the keep-alive activity (protocol 31).
211 - The filter code received some refactoring to make it more extendable, to
212 read better, and do better sanity checking.
214 - Really big numbers are now output using our own big-num routine rather
215 than casting them to a double and using a %.0f conversion.
217 - The pool_alloc library has received some minor improvements in alignment
220 - Added init_stat_x() function to avoid duplication of acl/xattr init code.
222 - The included zlib was upgraded from 1.2.3 to 1.2.8.
224 - Rsync can now be compiled to use an unmodified zlib library instead of
225 the tweaked one that is included with rsync. This will eventually
226 become the default, at which point we'll start the countdown to removing
227 the included zlib. Until then, feel free to configure using:
229 ./configure --with-included-zlib=no
233 - Added more conditional debug output.
235 - Fixed some build issues for android and minix.
