2955529b | 1 | NEWS for rsync 3.0.0 (UNRELEASED) |
2dc3db2a | 2 | Protocol: 30 (changed) |
2955529b | 3 | Changes since 2.6.9: |
36f59b58 | 4 | |
44a7ba45 | 5 | NOTABLE CHANGES IN BEHAVIOR: |
4f3c1df6 | 6 | |
3f655768 WD |
7 | - The handling of implied directories when using --relative has changed to |
8 | send them as directories (e.g. no implied dir is ever sent as a symlink). | |
9 | This avoids unexpected behavior and should not adversely affect most | |
10 | people. If you're one of those rare people who relied upon having an | |
11 | implied dir be duplicated as a symlink, you should specify the transfer | |
12 | of the symlink and the transfer of the referent directory as separate | |
13 | args. (See also --keep-dirlinks and --no-implied-dirs.) | |
14 | ||
15 | - Requesting a remote file list without specifying -r (--recursive) now | |
16 | sends the -d (--dirs) option to the remote rsync rather than sending -r | |
17 | along with an extra exclude of /*/*. If the remote rsync does not | |
18 | understand the -d option (i.e. it is 2.6.3 or older), you will need to | |
44a7ba45 | 19 | either turn off -d (--no-d), or specify -r --exclude='/*/*' manually. |

21 | BUG FIXES: |
22 | ||
3a72cc29 WD |
23 | - Fixed the output of -ii when combined with one of the --*-dest options: |
24 | it now itemizes all the items, not just the changed ones. | |
25 | ||
26 | - Made the output of all file types consistent when using a --*-dest | |
27 | option. Prior versions used to output too many creation events for | |
28 | matching items. | |
b4f02871 | 29 | |
9439c0cb WD |
30 | - The code that waits for a child pid now handles being interrupted by a |
31 | signal. This fixes a problem with the pre-xfer exec function not being | |
32 | able to get the exit status from the script. | |
3481bdf4 | 33 | |
4f3c1df6 WD |
34 | - A negated filter rule (with a '!' modifier) no longer loses the negation |
35 | when sending the filter rules to the remote rsync. | |
d0d0e41f | 36 | |
4f3c1df6 | 37 | - Fixed a problem with the --out-format (aka --log-format) option %f: it |
889ae39d WD |
38 | would output superfluous directory information for a non-daemon rsync. |
39 | ||
8b584075 WD |
40 | - Fixed a problem with -vv (double --verbose) and --stats when "pushing" |
41 | files (which includes local copies). Version 2.6.9 would complete the | |
42 | copy, but exit with an error when the receiver output its memory stats. | |
43 | ||
99effefc WD |
44 | - If --password-file is used on a non-daemon transfer, rsync now complains |
45 | and exits. This should help users figure out that they can't use this | |
46 | option to control a remote shell's password prompt. | |
e8dad395 | 47 | |
d762dfe9 WD |
48 | - Make sure that directory permissions of a newly-created destination |
49 | directory are handled right when --perms is left off. | |
50 | ||
4f3c1df6 WD |
51 | - The itemized output of a newly-created destination directory is now |
52 | output as a creation event, not a change event. | |
53 | ||
9c528e29 WD |
54 | - Improved --hard-link so that more corner cases are handled correctly |
55 | when combined with options such as --link-dest and/or --ignore-existing. | |
56 | ||
4f3c1df6 WD |
57 | - The --append option no longer updates a file that has the same size. |
58 | ||
59 | - Fixed a bug when combining --backup and --backup-dir with --inplace: | |
60 | any missing backup directories are now created. | |
61 | ||
62 | - Fixed a bug when using --backup and --inplace with --whole-file or | |
63 | --read-batch: backup files are actually created now. | |
64 | ||
0f8984ed WD |
65 | - Starting up an extra copy of an rsync daemon does not delete the pidfile |
66 | for the running daemon -- if the pidfile exists, the extra program will | |
67 | exit with an error. | |
68 | ||
69 | - The daemon pidfile is checked and created sooner in the startup sequence. | |
70 | ||
d46b5646 WD |
71 | - If a daemon module's "path" value is not an absolute pathname, the code |
72 | now makes it absolute internally (making it work properly). | |
73 | ||
ac1541f4 WD |
74 | ENHANCEMENTS: |
75 | ||
012d1a01 | 76 | - A new incremental-recursion algorithm is now used when rsync is talking |
4f3c1df6 | 77 | to another 3.x version. This starts the transfer going more quickly |
012d1a01 WD |
78 | (before all the files have been found), and requires much less memory. |
79 | See the --recursive option in the manpage for some restrictions. | |
80 | ||
d46b5646 | 81 | - Lowered memory use in the non-incremental-recursion algorithm for typical |
4f3c1df6 WD |
82 | option values (usually saving from 21-29 bytes per file). |
83 | ||
012d1a01 WD |
84 | - The default --delete algorithm is now --delete-during when talking to a |
85 | 3.x rsync. This is a faster scan than using --delete-before (which is | |
9439c0cb WD |
86 | the default when talking to older rsync versions), and is compatible with |
87 | the new incremental recursion mode. | |
012d1a01 | 88 | |
f89617f7 WD |
89 | - Rsync now allows multiple remote-source args to be specified rather than |
90 | having to rely on a special space-splitting side-effect of the remote- | |
91 | shell. Additional remote args must specify the same host or have an | |
92 | empty hostname, as seen here: :file1 ::module/file2. This means that | |
93 | local use of brace expansion now works: rsync -av host:path/{f1,f2} . | |
94 | ||
d46b5646 WD |
95 | - Added the --protect-args (-s) option, that tells rsync to send most of |
96 | the command-line args at the start of the transfer rather than as args | |
97 | to the remote-shell command. This protects them from space-splitting, | |
98 | and only interprets basic wildcard special shell characters (*?[). | |
99 | ||
9439c0cb WD |
100 | - Added the --delete-delay option, which is a more efficient way to delete |
101 | files at the end of the transfer without needing a separate delete pass. | |
c7871d98 | 102 | |
348d54d6 | 103 | - Added the --acls (-A) option to preserve Access Control Lists. This is |
4f3c1df6 WD |
104 | an improved version of the prior patch that was available, and it even |
105 | supports OS X ACLs. (If you need to have backward compatibility with | |
106 | old, patched versions of rsync, apply the acls.diff file from the patches | |
107 | dir.) | |
348d54d6 WD |
108 | |
109 | - Added the --xattrs (-X) option to preserver extended attributes. This is | |
110 | an improved version of the prior patch that was available. (If you need | |
4f3c1df6 WD |
111 | to have backward compatibility with old, patched versions of rsync, apply |
112 | the xattrs.diff file from the patches dir.) | |
348d54d6 | 113 | |
9439c0cb WD |
114 | - Added the --fake-super option that allows a non-super user to preserve |
115 | all attributes of a file by using a special extended-attribute idiom. | |
116 | There is also an analogous "fake super" option for an rsync daemon. | |
117 | ||
332cf6df | 118 | - Added the --iconv option, which allows rsync to convert filenames from |
0156c784 WD |
119 | one character-set to another during the transfer. The default is to make |
120 | this feature available as long as your system has iconv_open(). If | |
4f3c1df6 WD |
121 | compilation fails, specify --disable-iconv to configure, and then |
122 | rebuild. If you want rsync to perform character-set conversions by | |
123 | default, you can specify --enable-iconv=CONVERT_STRING with the default | |
124 | value for the --iconv option that you wish to use. For example, | |
d46b5646 | 125 | "--enable-iconv=." is a good choice. See the rsync manpage for an |
4f3c1df6 | 126 | explanation of the --iconv option's settings. |
332cf6df | 127 | |
d46b5646 | 128 | - Added the --skip-compress=LIST option to override the default list of |
9c528e29 | 129 | file suffixes that will not be compressed when using --compress. |
4f3c1df6 WD |
130 | |
131 | - The daemon's default for "dont compress" was extended to include: | |
132 | *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg | |
133 | The matching routine was also optimized to run more quickly. | |
9c528e29 | 134 | |
836ce36a WD |
135 | - The --max-delete option now outputs a warning if it skipped any file |
136 | deletions, including a count of how many deletions were skipped. (Older | |
137 | versions just silently stopped deleting things.) | |
138 | ||
139 | - You may specify --max-delete=0 to a 3.0.0 client to request that it warn | |
4f3c1df6 WD |
140 | about extraneous files without deleting anything. If you're not sure |
141 | what version the client is, you can use the less-obvious --max-delete=-1, | |
142 | as both old and new versions will treat that as the same request (though | |
143 | older versions don't warn). | |
8adc22e3 | 144 | |
3a5a7de6 | 145 | - The --hard-link option now uses less memory on both the sending and |
9439c0cb WD |
146 | receiving side for all protocol versions. For protocol 30, the use of a |
147 | hashtable on the sending side allows us to more efficiently convey to the | |
148 | receiver what files are linked together. This reduces the amount of data | |
149 | sent over the socket by a considerable margin (rather than adding more | |
150 | data), and limits the in-memory storage of the device+inode information | |
151 | to just the sending side for the new protocol 30, or to the receiving | |
152 | side when speaking an older protocol (note that older rsync versions kept | |
153 | the device+inode information on both sides). | |
3a5a7de6 | 154 | |
4f3c1df6 WD |
155 | - The filter rules now support a perishable ("p") modifier that marks rules |
156 | that should not have an effect in a directory that is being deleted. e.g. | |
157 | -f '-p .svn/' would only affect "live" .svn directories. | |
158 | ||
4f3c1df6 WD |
159 | - If we get an error setting the time on a symlink, we don't complain about |
160 | it anymore (since some operating systems don't support that, and it's not | |
161 | that important). | |
162 | ||
4f3c1df6 WD |
163 | - Protocol 30 now uses MD5 checksums instead of MD4. |
164 | ||
4f3c1df6 WD |
165 | - Changed the --append option to not checksum the existing data in the |
166 | destination file, which speeds up file appending. | |
167 | ||
168 | - Added the --append-verify option, which works like the older --append | |
169 | option (verifying the existing data in the destination file). For | |
170 | compatibility with older rsync versions, any use of --append that is | |
171 | talking protocol 29 or older will revert to the --append-verify method. | |
172 | ||
173 | - Documented and extended the support for the RSYNC_CONNECT_PROG variable | |
0f8984ed | 174 | that can be used to enhance the client side of a daemon connection. |
4f3c1df6 | 175 | |
0f8984ed WD |
176 | - Improved the dashes and double-quotes in the nroff manpage output. |
177 | ||
178 | - We now support a lot more --no-OPTION override options. | |
179 | ||
4968423e WD |
180 | INTERNAL: |
181 | ||
0e5dd898 WD |
182 | - The file-list sorting algorithm now uses a sort that keeps any same- |
183 | named items in the same order as they were specified. This allows | |
184 | rsync to always ensure that the first of the duplicates is the one | |
f45b64d8 WD |
185 | that will be included in the copy. The new sort was also faster |
186 | than the glibc version of qsort() and mergesort() in my testing. | |
0e5dd898 | 187 | |
348d54d6 WD |
188 | - Rsync now supports the transfer of 64-bit timestamps (time_t values). |
189 | ||
190 | - Fixed a build problem with older (2.x) versions of gcc. | |
191 | ||
4d2ea5a8 WD |
192 | - Added some isType() functions that make dealing with signed characters |
193 | easier without forcing variables via casts. | |
194 | ||
4f3c1df6 WD |
195 | - Changed strcat/strcpy/sprintf function calls to use safer versions. |
196 | ||
3a72cc29 WD |
197 | - Upgraded the included popt version to 1.10.2 and improved its use of |
198 | string-handling functions. | |
418da6d9 | 199 | |
d0d0e41f WD |
200 | - Added missing prototypes for compatibility functions from the lib dir. |
201 | ||
c7871d98 WD |
202 | - Configure determines if iconv() has a const arg, allowing us to avoid a |
203 | compiler warning. | |
204 | ||
205 | - Made the sending of some numbers more efficient for protocol 30. | |
d0d0e41f | 206 | |
d762dfe9 WD |
207 | - Make sure that a daemon process doesn't mind if the client was weird and |
208 | omitted the --server option. | |
209 | ||
d0d0e41f WD |
210 | - Improved the use of "const" on pointers. |
211 | ||
1c4ffe64 WD |
212 | - Improved J.W.'s pool_alloc routines to add a way of freeing older |
213 | sections of a pool's memory. | |
214 | ||
7c329ec7 WD |
215 | DEVELOPER RELATED: |
216 | ||
8798be8e WD |
217 | - Rsync is now licensed under the GPLv3 or later. |
218 | ||
4f3c1df6 WD |
219 | - When running the tests, we now put our per-test temp dirs into a sub- |
220 | directory named testtmp (which is created, if missing). This allows | |
221 | someone to symlink the testtmp directory to another filesystem (which is | |
222 | useful if the build dir's filesystem does not support ACLs and xattrs, | |
223 | and another file system does). | |
224 | ||
348d54d6 | 225 | - Rsync now has a way of handling protocol-version changes during the |
d46b5646 WD |
226 | development of a new protocol version. This causes any out-of-sync |
227 | versions to speak an older protocol rather than fail in a cryptic manner. | |
228 | This addition makes it safe to deploy a pre-release version that may | |
229 | interact with the public. This new exchange of sub-version info does not | |
230 | interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which | |
231 | does not have enough range to allow the main protocol number to be | |
232 | incremented for every minor tweak in that happens during development). |
