2Protocol: 28 (changed)
3Changes 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 (which is used to estimate the remaining transfer
19 time).
20
21 * The configure script now accepts --with-rsyncd-conf=PATH
22 to override the default value of the /etc/rsyncd.conf file.
23
24 * Added a couple extra diffs in the "patches" dir, removed the
25 ones that got applied, and rebuilt the rest.
26
27 BUG FIXES:
28
29 * When -x (--one-file-system) is combined with -L (--copy-links)
30 or --copy-unsafe-links, no symlinked files are skipped, even
31 if the referant file is on a different filesystem.
32
33 * The --link-dest code now works properly for a non-root user
34 when (1) the UIDs of the source and destination differ and -o
35 was specified, or (2) when the group of the source can't be
36 used on the destination and -g was specified.
37
38 * Fixed a bug in the handling of -H (hard-links) that might
39 cause the expanded PATH/NAME value of the current item to
40 get overwritten (due to an expanded-name caching bug).
41
42 * We now reset the "new data has been sent" flag at the start
43 of each file we send. This makes sure that an interrupted
44 transfer with the --partial option set doesn't keep a shorter
45 temp file than the current basis file when no new data has been
46 transfered over the wire for that file.
47
48 * Fixed a byte-order problem in --batch-mode on big-endian
49 machines. (Jay Fenlason)
50
51 * Fixed configure bug when running "./configure --disable-ipv6".
52
53 * Fixed "make test" bug when build dir is not the source dir.
54
55 * When using --cvs-exclude, the exclude items we get from a
56 directory's .cvsignore file once again only affect that one
57 directory (and not all following directories too).
58
59 * When transferring a file that has group 0 with -g specified
60 (typically via -a) and not enough privs to retain the group,
61 rsync no longer complains about "chown" failing.
62
63 * When specifying the USER@HOST: prefix for a file, the USER
64 part can now contain an '@', if needed (i.e. the last '@'
65 is used to find the HOST, not the first).
66
67 * Fixed some bugs in the handling of group IDs for non-root
68 users: (1) It properly handles a group that the sender didn't
69 have a name for (it would previously skip changing the group
70 on any files in that group). (2) If --numeric-ids is used,
71 rsync no longer attempts to set groups that the user doesn't
72 have the permission to set.
73
74 * Fixed the "refuse options" setting in the rsyncd.conf file.
75
76 * Improved the -x (--one-file-system) flag's handling of any
77 mount-point directories we encounter. It is both more optimal
78 (in that it no longer does a useless scan of the contents of
79 the mount-point dirs) and also fixes a bug where a remaped
80 mount of the original filesystem could get discovered on a
81 disk we should be ignoring.
82
83 * Rsync no longer discards a double-slash at the start of a filename
84 when trying to open the file. It also no longer constructs names
85 that start with a double slash (unless the user supplied them).
86
87 * Fixed compilation problem on Tru64 Unix (having to do with
88 sockaddr.sa_len and sockaddr.sin_len).
89
90 INTERNAL:
91
92 * Most of the I/O is now buffered, which results in a pretty
93 large speedup when running under MS Windows. (Craig Barratt)
94
95 * Optimizations to the name-handling/comparing code have made
96 some significant reductions in user-CPU time for large file
97 sets.
98
99 * Some variable-type cleanup that makes the code more consistent.
100
101 * Reduced memory requirements of hard link preservation.
102 (J.W. Schultz)
103
104 * Implemented a new algorithm for hard-link handling that speeds
105 up the code significantly. (J.W. Schultz and Wayne Davison)
106
107 * The --hard-link option now uses the first existing file in the
108 group of linked files as the basis for the transfer. This
109 prevents the sub-optimal transfer of a file's data when a new
110 hardlink is added on the sending side and it sorts alphabetically
111 earlier in the list than the files that are already present on the
112 receiving side.
113
114 * Dropped support for protocol versions less than 20
115 (2.3.0 released 15 Mar 1999) and activated warnings for
116 protocols less than 25 (2.5.0 released 23 Aug 2001)
117 (Wayne Davison and J.W. Schultz, severally)
118
119 * More optimal data transmission for --hard-links (protocol 28).
120
121 * More optimal data transmission for --checksum (protocol 28).
122
123 * Less memory is used when --checksum is specified.
124
125 * Less memory is used in the file list (a per-file savings).
126
127 * Changed hardlink info and file_struct + strings to use
128 allocation pools. This reduces memory use for large
129 filesets and permits freeing memory to the OS. (J.W. Schultz)
130
131 * The 2 pipes used between the receiver and generator processes
132 (which are forked on the same machine) were reduced to 1 pipe
133 and the protocol improved so that (1) it is now impossible to
134 have the "redo" pipe fill up and hang rsync, and (2) trailing
135 messages from the receiver don't get lost on their way through
136 the generator over to the sender (the latter mainly affected
137 hard-link messages and verbose --stats output).
138
139 * The reading & writing of the file list in batch-mode is now
140 handled by the same code that sends & receives the list over
141 the wire. This makes it much easier to maintain.
142
143 * Improved the internal uid/gid code to be more portable and
144 a little more optimized.
