2047
log is bzr's default tool for exploring the history of a branch.
2048
The branch to use is taken from the first parameter. If no parameters
2049
are given, the branch containing the working directory is logged.
2050
Here are some simple examples::
2052
bzr log log the current branch
2053
bzr log foo.py log a file in its branch
2054
bzr log http://server/branch log a branch on a server
2056
The filtering, ordering and information shown for each revision can
2057
be controlled as explained below. By default, all revisions are
2058
shown sorted (topologically) so that newer revisions appear before
2059
older ones and descendants always appear before ancestors. If displayed,
2060
merged revisions are shown indented under the revision in which they
2065
The log format controls how information about each revision is
2066
displayed. The standard log formats are called ``long``, ``short``
2067
and ``line``. The default is long. See ``bzr help log-formats``
2068
for more details on log formats.
2070
The following options can be used to control what information is
2073
-l N display a maximum of N revisions
2074
-n N display N levels of revisions (0 for all, 1 for collapsed)
2075
-v display a status summary (delta) for each revision
2076
-p display a diff (patch) for each revision
2077
--show-ids display revision-ids (and file-ids), not just revnos
2079
Note that the default number of levels to display is a function of the
2080
log format. If the -n option is not used, the standard log formats show
2081
just the top level (mainline).
2083
Status summaries are shown using status flags like A, M, etc. To see
2084
the changes explained using words like ``added`` and ``modified``
2085
instead, use the -vv option.
2089
To display revisions from oldest to newest, use the --forward option.
2090
In most cases, using this option will have little impact on the total
2091
time taken to produce a log, though --forward does not incrementally
2092
display revisions like --reverse does when it can.
2094
:Revision filtering:
2096
The -r option can be used to specify what revision or range of revisions
2097
to filter against. The various forms are shown below::
2099
-rX display revision X
2100
-rX.. display revision X and later
2101
-r..Y display up to and including revision Y
2102
-rX..Y display from X to Y inclusive
2104
See ``bzr help revisionspec`` for details on how to specify X and Y.
2105
Some common examples are given below::
2107
-r-1 show just the tip
2108
-r-10.. show the last 10 mainline revisions
2109
-rsubmit:.. show what's new on this branch
2110
-rancestor:path.. show changes since the common ancestor of this
2111
branch and the one at location path
2112
-rdate:yesterday.. show changes since yesterday
2114
When logging a range of revisions using -rX..Y, log starts at
2115
revision Y and searches back in history through the primary
2116
("left-hand") parents until it finds X. When logging just the
2117
top level (using -n1), an error is reported if X is not found
2118
along the way. If multi-level logging is used (-n0), X may be
2119
a nested merge revision and the log will be truncated accordingly.
2123
If parameters are given and the first one is not a branch, the log
2124
will be filtered to show only those revisions that changed the
2125
nominated files or directories.
2127
Filenames are interpreted within their historical context. To log a
2128
deleted file, specify a revision range so that the file existed at
2129
the end or start of the range.
2131
Historical context is also important when interpreting pathnames of
2132
renamed files/directories. Consider the following example:
2134
* revision 1: add tutorial.txt
2135
* revision 2: modify tutorial.txt
2136
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2140
* ``bzr log guide.txt`` will log the file added in revision 1
2142
* ``bzr log tutorial.txt`` will log the new file added in revision 3
2144
* ``bzr log -r2 -p tutorial.txt`` will show the changes made to
2145
the original file in revision 2.
2147
* ``bzr log -r2 -p guide.txt`` will display an error message as there
2148
was no file called guide.txt in revision 2.
2150
Renames are always followed by log. By design, there is no need to
2151
explicitly ask for this (and no way to stop logging a file back
2152
until it was last renamed).
2156
The --message option can be used for finding revisions that match a
2157
regular expression in a commit message.
2161
GUI tools and IDEs are often better at exploring history than command
2162
line tools. You may prefer qlog or glog from the QBzr and Bzr-Gtk packages
2163
respectively for example. (TortoiseBzr uses qlog for displaying logs.) See
2164
http://bazaar-vcs.org/BzrPlugins and http://bazaar-vcs.org/IDEIntegration.
2166
Web interfaces are often better at exploring history than command line
2167
tools, particularly for branches on servers. You may prefer Loggerhead
2168
or one of its alternatives. See http://bazaar-vcs.org/WebInterface.
2170
You may find it useful to add the aliases below to ``bazaar.conf``::
2174
top = log -l10 --line
2177
``bzr tip`` will then show the latest revision while ``bzr top``
2178
will show the last 10 mainline revisions. To see the details of a
2179
particular revision X, ``bzr show -rX``.
2181
If you are interested in looking deeper into a particular merge X,
2182
use ``bzr log -n0 -rX``.
2184
``bzr log -v`` on a branch with lots of history is currently
2185
very slow. A fix for this issue is currently under development.
2186
With or without that fix, it is recommended that a revision range
2187
be given when using the -v option.
2189
bzr has a generic full-text matching plugin, bzr-search, that can be
2190
used to find revisions matching user names, commit messages, etc.
2191
Among other features, this plugin can find all revisions containing
2192
a list of words but not others.
2194
When exploring non-mainline history on large projects with deep
2195
history, the performance of log can be greatly improved by installing
2196
the historycache plugin. This plugin buffers historical information
2197
trading disk space for faster speed.

"""Commit changes into a new revision.
2843
An explanatory message needs to be given for each commit. This is
2844
often done by using the --message option (getting the message from the
2845
command line) or by using the --file option (getting the message from
2846
a file). If neither of these options is given, an editor is opened for
2847
the user to enter the message. To see the changed files in the
2848
boilerplate text loaded into the editor, use the --show-diff option.
2850
By default, the entire tree is committed and the person doing the
2851
commit is assumed to be the author. These defaults can be overridden
2856
If selected files are specified, only changes to those files are
2857
committed. If a directory is specified then the directory and
2858
everything within it is committed.
2860
When excludes are given, they take precedence over selected files.
2861
For example, to commit only changes within foo, but not changes
2864
bzr commit foo -x foo/bar
2866
A selective commit after a merge is not yet supported.
2870
If the author of the change is not the same person as the committer,
2871
you can specify the author's name using the --author option. The
2872
name should be in the same format as a committer-id, e.g.
2873
"John Doe <jdoe@example.com>". If there is more than one author of
2874
the change you can specify the option multiple times, once for each
2879
A common mistake is to forget to add a new file or directory before
2880
running the commit command. The --strict option checks for unknown
2881
files and aborts the commit if any are found. More advanced pre-commit
2882
checks can be implemented by defining hooks. See ``bzr help hooks``
2887
If you accidentially commit the wrong changes or make a spelling
2888
mistake in the commit message say, you can use the uncommit command
2889
to undo it. See ``bzr help uncommit`` for details.
2891
Hooks can also be configured to run after a commit. This allows you
2892
to trigger updates to external systems like bug trackers. The --fixes
2893
option can be used to record the association between a revision and
2894
one or more bugs. See ``bzr help bugs`` for details.
2896
A selective commit may fail in some cases where the committed
2897
tree would be invalid. Consider::
2902
bzr commit foo -m "committing foo"
2903
bzr mv foo/bar foo/baz
2906
bzr commit foo/bar -m "committing bar but not baz"
2908
In the example above, the last commit will fail by design. This gives
2909
the user the opportunity to decide whether they want to commit the
2910
rename at the same time, separately first, or not at all. (As a general
2911
rule, when in doubt, Bazaar has a policy of Doing the Safe Thing.)

3553
The source of the merge can be specified either in the form of a branch,
3554
or in the form of a path to a file containing a merge directive generated
3555
with bzr send. If neither is specified, the default is the upstream branch
3556
or the branch most recently merged using --remember.
3558
When merging a branch, by default the tip will be merged. To pick a different
3559
revision, pass --revision. If you specify two values, the first will be used as
3560
BASE and the second one as OTHER. Merging individual revisions, or a subset of
3561
available revisions, like this is commonly referred to as "cherrypicking".
3563
Revision numbers are always relative to the branch being merged.
3565
By default, bzr will try to merge in all new work from the other
3566
branch, automatically determining an appropriate base. If this
3567
fails, you may need to give an explicit base.
3569
Merge will do its best to combine the changes in two branches, but there
3570
are some kinds of problems only a human can fix. When it encounters those,
3571
it will mark a conflict. A conflict means that you need to fix something,
3572
before you should commit.
3574
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
3576
If there is no default branch set, the first merge will set it. After
3577
that, you can omit the branch to use the default. To change the
3578
default, use --remember. The value will only be saved if the remote
3579
location can be accessed.
3581
The results of the merge are placed into the destination working
3582
directory, where they can be reviewed (with bzr diff), tested, and then
3583
committed to record the result of the merge.
3585
merge refuses to run if there are any uncommitted changes, unless
3588
To select only some changes to merge, use "merge -i", which will prompt
3589
you to apply each diff hunk and file change, similar to "shelve".

bzr merge ../bzr.dev

4006
Giving a list of files will revert only those files. Otherwise, all files
4007
will be reverted. If the revision is not specified with '--revision', the
4008
last committed revision is used.
4010
To remove only some changes, without reverting to a prior version, use
4011
merge instead. For example, "merge . --revision -2..-3" will remove the
4012
changes introduced by -2, without affecting the changes introduced by -1.
4013
Or to remove certain changes on a hunk-by-hunk basis, see the Shelf plugin.
4015
By default, any files that have been manually changed will be backed up
4016
first. (Files changed only by merge are not backed up.) Backup files have
4017
'.~#~' appended to their name, where # is a number.
4019
When you provide files, you can use their current pathname or the pathname
4020
from the target revision. So you can use revert to "undelete" a file by
4021
name. If you name a directory, all the contents of that directory will be
4024
Any files that have been newly added since that revision will be deleted,
4025
with a backup kept if appropriate. Directories containing unknown files
4026
will not be deleted.
4028
The working tree contains a list of pending merged revisions, which will
4029
be included as parents in the next commit. Normally, revert clears that
4030
list as well as reverting the files. If any files are specified, revert
4031
leaves the pending merge list alone and reverts only the files. Use "bzr
4032
revert ." in the tree root to revert all files but keep the merge record,

4950
* An optional bundle of revision data, so that the changes can be applied

4957
people can check it later.
4959
The submit branch defaults to the parent, but can be overridden. Both
4960
submit branch and public branch will be remembered if supplied.
4962
If a public_branch is known for the submit_branch, that public submit
4963
branch is used in the merge instructions. This means that a local mirror
4964
can be used as your actual submit branch, once you have set public_branch
4967
Mail is sent using your preferred mail program. This should be transparent
4968
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4969
If the preferred client can't be found (or used), your editor will be used.
4971
To use a specific mail program, set the mail_client configuration option.
4972
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4973
specific clients are "claws", "evolution", "kmail", "mail.app" (MacOS X's
4974
Mail.app), "mutt", and "thunderbird"; generic options are "default",
4975
"editor", "emacsclient", "mapi", and "xdg-email". Plugins may also add
4978
If mail is being sent, a to address is required. This can be supplied
4979
either on the commandline, by setting the submit_to configuration
4980
option in the branch itself or the child_submit_to configuration option
4981
in the submit branch.

merge directive format 2. It is significantly faster and smaller than
