log is bzr's default tool for exploring the history of a branch.
2052
The branch to use is taken from the first parameter. If no parameters
2053
are given, the branch containing the working directory is logged.
2054
Here are some simple examples::
2056
bzr log log the current branch
2057
bzr log foo.py log a file in its branch
2058
bzr log http://server/branch log a branch on a server
2060
The filtering, ordering and information shown for each revision can
2061
be controlled as explained below. By default, all revisions are
2062
shown sorted (topologically) so that newer revisions appear before
2063
older ones and descendants always appear before ancestors. If displayed,
2064
merged revisions are shown indented under the revision in which they
2069
The log format controls how information about each revision is
2070
displayed. The standard log formats are called ``long``, ``short``
2071
and ``line``. The default is long. See ``bzr help log-formats``
2072
for more details on log formats.
2074
The following options can be used to control what information is
2077
-l N display a maximum of N revisions
2078
-n N display N levels of revisions (0 for all, 1 for collapsed)
2079
-v display a status summary (delta) for each revision
2080
-p display a diff (patch) for each revision
2081
--show-ids display revision-ids (and file-ids), not just revnos
2083
Note that the default number of levels to display is a function of the
2084
log format. If the -n option is not used, the standard log formats show
2085
just the top level (mainline).
2087
Status summaries are shown using status flags like A, M, etc. To see
2088
the changes explained using words like ``added`` and ``modified``
2089
instead, use the -vv option.
2093
To display revisions from oldest to newest, use the --forward option.
2094
In most cases, using this option will have little impact on the total
2095
time taken to produce a log, though --forward does not incrementally
2096
display revisions like --reverse does when it can.
2098
:Revision filtering:
2100
The -r option can be used to specify what revision or range of revisions
2101
to filter against. The various forms are shown below::
2103
-rX display revision X
2104
-rX.. display revision X and later
2105
-r..Y display up to and including revision Y
2106
-rX..Y display from X to Y inclusive
2108
See ``bzr help revisionspec`` for details on how to specify X and Y.
2109
Some common examples are given below::
2111
-r-1 show just the tip
2112
-r-10.. show the last 10 mainline revisions
2113
-rsubmit:.. show what's new on this branch
2114
-rancestor:path.. show changes since the common ancestor of this
2115
branch and the one at location path
2116
-rdate:yesterday.. show changes since yesterday
2118
When logging a range of revisions using -rX..Y, log starts at
2119
revision Y and searches back in history through the primary
2120
("left-hand") parents until it finds X. When logging just the
2121
top level (using -n1), an error is reported if X is not found
2122
along the way. If multi-level logging is used (-n0), X may be
2123
a nested merge revision and the log will be truncated accordingly.
2127
If parameters are given and the first one is not a branch, the log
2128
will be filtered to show only those revisions that changed the
2129
nominated files or directories.
2131
Filenames are interpreted within their historical context. To log a
2132
deleted file, specify a revision range so that the file existed at
2133
the end or start of the range.
2135
Historical context is also important when interpreting pathnames of
2136
renamed files/directories. Consider the following example:
2138
* revision 1: add tutorial.txt
2139
* revision 2: modify tutorial.txt
2140
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2144
* ``bzr log guide.txt`` will log the file added in revision 1
2146
* ``bzr log tutorial.txt`` will log the new file added in revision 3
2148
* ``bzr log -r2 -p tutorial.txt`` will show the changes made to
2149
the original file in revision 2.
2151
* ``bzr log -r2 -p guide.txt`` will display an error message as there
2152
was no file called guide.txt in revision 2.
2154
Renames are always followed by log. By design, there is no need to
2155
explicitly ask for this (and no way to stop logging a file back
2156
until it was last renamed).
2160
The --message option can be used for finding revisions that match a
2161
regular expression in a commit message.
2165
GUI tools and IDEs are often better at exploring history than command
2166
line tools. You may prefer qlog or glog from the QBzr and Bzr-Gtk packages
2167
respectively for example. (TortoiseBzr uses qlog for displaying logs.) See
2168
http://bazaar-vcs.org/BzrPlugins and http://bazaar-vcs.org/IDEIntegration.
2170
Web interfaces are often better at exploring history than command line
2171
tools, particularly for branches on servers. You may prefer Loggerhead
2172
or one of its alternatives. See http://bazaar-vcs.org/WebInterface.
2174
You may find it useful to add the aliases below to ``bazaar.conf``::
2178
top = log -l10 --line
2181
``bzr tip`` will then show the latest revision while ``bzr top``
2182
will show the last 10 mainline revisions. To see the details of a
2183
particular revision X, ``bzr show -rX``.
2185
If you are interested in looking deeper into a particular merge X,
2186
use ``bzr log -n0 -rX``.
2188
``bzr log -v`` on a branch with lots of history is currently
2189
very slow. A fix for this issue is currently under development.
2190
With or without that fix, it is recommended that a revision range
2191
be given when using the -v option.
2193
bzr has a generic full-text matching plugin, bzr-search, that can be
2194
used to find revisions matching user names, commit messages, etc.
2195
Among other features, this plugin can find all revisions containing
2196
a list of words but not others.
2198
When exploring non-mainline history on large projects with deep
2199
history, the performance of log can be greatly improved by installing
2200
the historycache plugin. This plugin buffers historical information
2201
trading disk space for faster speed.

"""Commit changes into a new revision.
2854
An explanatory message needs to be given for each commit. This is
2855
often done by using the --message option (getting the message from the
2856
command line) or by using the --file option (getting the message from
2857
a file). If neither of these options is given, an editor is opened for
2858
the user to enter the message. To see the changed files in the
2859
boilerplate text loaded into the editor, use the --show-diff option.
2861
By default, the entire tree is committed and the person doing the
2862
commit is assumed to be the author. These defaults can be overridden
2867
If selected files are specified, only changes to those files are
2868
committed. If a directory is specified then the directory and
2869
everything within it is committed.
2871
When excludes are given, they take precedence over selected files.
2872
For example, to commit only changes within foo, but not changes
2875
bzr commit foo -x foo/bar
2877
A selective commit after a merge is not yet supported.
2881
If the author of the change is not the same person as the committer,
2882
you can specify the author's name using the --author option. The
2883
name should be in the same format as a committer-id, e.g.
2884
"John Doe <jdoe@example.com>". If there is more than one author of
2885
the change you can specify the option multiple times, once for each
2890
A common mistake is to forget to add a new file or directory before
2891
running the commit command. The --strict option checks for unknown
2892
files and aborts the commit if any are found. More advanced pre-commit
2893
checks can be implemented by defining hooks. See ``bzr help hooks``
2898
If you accidentially commit the wrong changes or make a spelling
2899
mistake in the commit message say, you can use the uncommit command
2900
to undo it. See ``bzr help uncommit`` for details.
2902
Hooks can also be configured to run after a commit. This allows you
2903
to trigger updates to external systems like bug trackers. The --fixes
2904
option can be used to record the association between a revision and
2905
one or more bugs. See ``bzr help bugs`` for details.
2907
A selective commit may fail in some cases where the committed
2908
tree would be invalid. Consider::
2913
bzr commit foo -m "committing foo"
2914
bzr mv foo/bar foo/baz
2917
bzr commit foo/bar -m "committing bar but not baz"
2919
In the example above, the last commit will fail by design. This gives
2920
the user the opportunity to decide whether they want to commit the
2921
rename at the same time, separately first, or not at all. (As a general
2922
rule, when in doubt, Bazaar has a policy of Doing the Safe Thing.)

3564
The source of the merge can be specified either in the form of a branch,
3565
or in the form of a path to a file containing a merge directive generated
3566
with bzr send. If neither is specified, the default is the upstream branch
3567
or the branch most recently merged using --remember.
3569
When merging a branch, by default the tip will be merged. To pick a different
3570
revision, pass --revision. If you specify two values, the first will be used as
3571
BASE and the second one as OTHER. Merging individual revisions, or a subset of
3572
available revisions, like this is commonly referred to as "cherrypicking".
3574
Revision numbers are always relative to the branch being merged.
3576
By default, bzr will try to merge in all new work from the other
3577
branch, automatically determining an appropriate base. If this
3578
fails, you may need to give an explicit base.
3580
Merge will do its best to combine the changes in two branches, but there
3581
are some kinds of problems only a human can fix. When it encounters those,
3582
it will mark a conflict. A conflict means that you need to fix something,
3583
before you should commit.
3585
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
3587
If there is no default branch set, the first merge will set it. After
3588
that, you can omit the branch to use the default. To change the
3589
default, use --remember. The value will only be saved if the remote
3590
location can be accessed.
3592
The results of the merge are placed into the destination working
3593
directory, where they can be reviewed (with bzr diff), tested, and then
3594
committed to record the result of the merge.
3596
merge refuses to run if there are any uncommitted changes, unless
3599
To select only some changes to merge, use "merge -i", which will prompt
3600
you to apply each diff hunk and file change, similar to "shelve".

To merge the latest revision from bzr.dev::
3605
bzr merge ../bzr.dev

4017
Giving a list of files will revert only those files. Otherwise, all files
4018
will be reverted. If the revision is not specified with '--revision', the
4019
last committed revision is used.
4021
To remove only some changes, without reverting to a prior version, use
4022
merge instead. For example, "merge . --revision -2..-3" will remove the
4023
changes introduced by -2, without affecting the changes introduced by -1.
4024
Or to remove certain changes on a hunk-by-hunk basis, see the Shelf plugin.
4026
By default, any files that have been manually changed will be backed up
4027
first. (Files changed only by merge are not backed up.) Backup files have
4028
'.~#~' appended to their name, where # is a number.
4030
When you provide files, you can use their current pathname or the pathname
4031
from the target revision. So you can use revert to "undelete" a file by
4032
name. If you name a directory, all the contents of that directory will be
4035
Any files that have been newly added since that revision will be deleted,
4036
with a backup kept if appropriate. Directories containing unknown files
4037
will not be deleted.
4039
The working tree contains a list of pending merged revisions, which will
4040
be included as parents in the next commit. Normally, revert clears that
4041
list as well as reverting the files. If any files are specified, revert
4042
leaves the pending merge list alone and reverts only the files. Use "bzr
4043
revert ." in the tree root to revert all files but keep the merge record,

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

4968
people can check it later.
4970
The submit branch defaults to the parent, but can be overridden. Both
4971
submit branch and public branch will be remembered if supplied.
4973
If a public_branch is known for the submit_branch, that public submit
4974
branch is used in the merge instructions. This means that a local mirror
4975
can be used as your actual submit branch, once you have set public_branch
4978
Mail is sent using your preferred mail program. This should be transparent
4979
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4980
If the preferred client can't be found (or used), your editor will be used.
4982
To use a specific mail program, set the mail_client configuration option.
4983
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4984
specific clients are "claws", "evolution", "kmail", "mail.app" (MacOS X's
4985
Mail.app), "mutt", and "thunderbird"; generic options are "default",
4986
"editor", "emacsclient", "mapi", and "xdg-email". Plugins may also add
4989
If mail is being sent, a to address is required. This can be supplied
4990
either on the commandline, by setting the submit_to configuration
4991
option in the branch itself or the child_submit_to configuration option
4992
in the submit branch.
