In recursive mode (the default), files are treated the same way

1991
The filtering, ordering and information shown for each revision can
1992
be controlled as explained below. By default, all revisions are
1993
shown sorted (topologically) so that newer revisions appear before
1994
older ones and descendants always appear before ancestors. If displayed,
1995
merged revisions are shown indented under the revision in which they
2000
The log format controls how information about each revision is
2001
displayed. The standard log formats are called ``long``, ``short``
2002
and ``line``. The default is long. See ``bzr help log-formats``
2003
for more details on log formats.
2005
The following options can be used to control what information is
2008
-l N display a maximum of N revisions
2009
-n N display N levels of revisions (0 for all, 1 for collapsed)
2010
-v display a status summary (delta) for each revision
2011
-p display a diff (patch) for each revision
2012
--show-ids display revision-ids (and file-ids), not just revnos
2014
Note that the default number of levels to display is a function of the
2015
log format. If the -n option is not used, the standard log formats show
2016
just the top level (mainline).
2018
Status summaries are shown using status flags like A, M, etc. To see
2019
the changes explained using words like ``added`` and ``modified``
2020
instead, use the -vv option.
2024
To display revisions from oldest to newest, use the --forward option.
2025
In most cases, using this option will have little impact on the total
2026
time taken to produce a log, though --forward does not incrementally
2027
display revisions like --reverse does when it can.
2029
:Revision filtering:
2031
The -r option can be used to specify what revision or range of revisions
2032
to filter against. The various forms are shown below::
2034
-rX display revision X
2035
-rX.. display revision X and later
2036
-r..Y display up to and including revision Y
2037
-rX..Y display from X to Y inclusive
2039
See ``bzr help revisionspec`` for details on how to specify X and Y.
2040
Some common examples are given below::
2042
-r-1 show just the tip
2043
-r-10.. show the last 10 mainline revisions
2044
-rsubmit:.. show what's new on this branch
2045
-rancestor:path.. show changes since the common ancestor of this
2046
branch and the one at location path
2047
-rdate:yesterday.. show changes since yesterday
2049
When logging a range of revisions using -rX..Y, log starts at
2050
revision Y and searches back in history through the primary
2051
("left-hand") parents until it finds X. When logging just the
2052
top level (using -n1), an error is reported if X is not found
2053
along the way. If multi-level logging is used (-n0), X may be
2054
a nested merge revision and the log will be truncated accordingly.
2058
If parameters are given and the first one is not a branch, the log
2059
will be filtered to show only those revisions that changed the
2060
nominated files or directories.
2062
Filenames are interpreted within their historical context. To log a
2063
deleted file, specify a revision range so that the file existed at
2064
the end or start of the range.
2066
Historical context is also important when interpreting pathnames of
2067
renamed files/directories. Consider the following example:
2069
* revision 1: add tutorial.txt
2070
* revision 2: modify tutorial.txt
2071
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2075
* ``bzr log guide.txt`` will log the file added in revision 1
2077
* ``bzr log tutorial.txt`` will log the new file added in revision 3
2079
* ``bzr log -r2 -p tutorial.txt`` will show the changes made to
2080
the original file in revision 2.
2082
* ``bzr log -r2 -p guide.txt`` will display an error message as there
2083
was no file called guide.txt in revision 2.
2085
Renames are always followed by log. By design, there is no need to
2086
explicitly ask for this (and no way to stop logging a file back
2087
until it was last renamed).
2091
The --message option can be used for finding revisions that match a
2092
regular expression in a commit message.
2096
GUI tools and IDEs are often better at exploring history than command
2097
line tools. You may prefer qlog or glog from the QBzr and Bzr-Gtk packages
2098
respectively for example. (TortoiseBzr uses qlog for displaying logs.) See
2099
http://bazaar-vcs.org/BzrPlugins and http://bazaar-vcs.org/IDEIntegration.
2101
Web interfaces are often better at exploring history than command line
2102
tools, particularly for branches on servers. You may prefer Loggerhead
2103
or one of its alternatives. See http://bazaar-vcs.org/WebInterface.
2105
You may find it useful to add the aliases below to ``bazaar.conf``::
2109
top = log -l10 --line
2112
``bzr tip`` will then show the latest revision while ``bzr top``
2113
will show the last 10 mainline revisions. To see the details of a
2114
particular revision X, ``bzr show -rX``.
2116
If you are interested in looking deeper into a particular merge X,
2117
use ``bzr log -n0 -rX``.
2119
``bzr log -v`` on a branch with lots of history is currently
2120
very slow. A fix for this issue is currently under development.
2121
With or without that fix, it is recommended that a revision range
2122
be given when using the -v option.
2124
bzr has a generic full-text matching plugin, bzr-search, that can be
2125
used to find revisions matching user names, commit messages, etc.
2126
Among other features, this plugin can find all revisions containing
2127
a list of words but not others.
2129
When exploring non-mainline history on large projects with deep
2130
history, the performance of log can be greatly improved by installing
2131
the historycache plugin. This plugin buffers historical information
2132
trading disk space for faster speed.

"""Commit changes into a new revision.
2778
An explanatory message needs to be given for each commit. This is
2779
often done by using the --message option (getting the message from the
2780
command line) or by using the --file option (getting the message from
2781
a file). If neither of these options is given, an editor is opened for
2782
the user to enter the message. To see the changed files in the
2783
boilerplate text loaded into the editor, use the --show-diff option.
2785
By default, the entire tree is committed and the person doing the
2786
commit is assumed to be the author. These defaults can be overridden
2791
If selected files are specified, only changes to those files are
2792
committed. If a directory is specified then the directory and
2793
everything within it is committed.
2795
When excludes are given, they take precedence over selected files.
2796
For example, to commit only changes within foo, but not changes
2799
bzr commit foo -x foo/bar
2801
A selective commit after a merge is not yet supported.
2805
If the author of the change is not the same person as the committer,
2806
you can specify the author's name using the --author option. The
2807
name should be in the same format as a committer-id, e.g.
2808
"John Doe <jdoe@example.com>". If there is more than one author of
2809
the change you can specify the option multiple times, once for each
2814
A common mistake is to forget to add a new file or directory before
2815
running the commit command. The --strict option checks for unknown
2816
files and aborts the commit if any are found. More advanced pre-commit
2817
checks can be implemented by defining hooks. See ``bzr help hooks``
2822
If you accidentially commit the wrong changes or make a spelling
2823
mistake in the commit message say, you can use the uncommit command
2824
to undo it. See ``bzr help uncommit`` for details.
2826
Hooks can also be configured to run after a commit. This allows you
2827
to trigger updates to external systems like bug trackers. The --fixes
2828
option can be used to record the association between a revision and
2829
one or more bugs. See ``bzr help bugs`` for details.
2831
A selective commit may fail in some cases where the committed
2832
tree would be invalid. Consider::
2837
bzr commit foo -m "committing foo"
2838
bzr mv foo/bar foo/baz
2841
bzr commit foo/bar -m "committing bar but not baz"
2843
In the example above, the last commit will fail by design. This gives
2844
the user the opportunity to decide whether they want to commit the
2845
rename at the same time, separately first, or not at all. (As a general
2846
rule, when in doubt, Bazaar has a policy of Doing the Safe Thing.)

The source of the merge can be specified either in the form of a branch,

or in the form of a path to a file containing a merge directive generated
3480
with bzr send. If neither is specified, the default is the upstream branch
3481
or the branch most recently merged using --remember.
3483
When merging a branch, by default the tip will be merged. To pick a different
3484
revision, pass --revision. If you specify two values, the first will be used as
3485
BASE and the second one as OTHER. Merging individual revisions, or a subset of
3486
available revisions, like this is commonly referred to as "cherrypicking".
3488
Revision numbers are always relative to the branch being merged.
3490
By default, bzr will try to merge in all new work from the other
3491
branch, automatically determining an appropriate base. If this
3492
fails, you may need to give an explicit base.
3494
Merge will do its best to combine the changes in two branches, but there
3495
are some kinds of problems only a human can fix. When it encounters those,
3496
it will mark a conflict. A conflict means that you need to fix something,
3497
before you should commit.
3499
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
3501
If there is no default branch set, the first merge will set it. After
3502
that, you can omit the branch to use the default. To change the
3503
default, use --remember. The value will only be saved if the remote
3504
location can be accessed.
3506
The results of the merge are placed into the destination working
3507
directory, where they can be reviewed (with bzr diff), tested, and then

To remove only some changes, without reverting to a prior version, use

A merge directive provides many things needed for requesting merges:
4842
* A machine-readable description of the merge to perform
4844
* An optional patch that is a preview of the changes requested
4846
* An optional bundle of revision data, so that the changes can be applied

up-to-date), so that the receiver can perform the merge using the
4852
public_branch. The public_branch is always included if known, so that
4853
people can check it later.
4855
The submit branch defaults to the parent, but can be overridden. Both
4856
submit branch and public branch will be remembered if supplied.
4858
If a public_branch is known for the submit_branch, that public submit
4859
branch is used in the merge instructions. This means that a local mirror
4860
can be used as your actual submit branch, once you have set public_branch
4863
Mail is sent using your preferred mail program. This should be transparent
4864
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4865
If the preferred client can't be found (or used), your editor will be used.
4867
To use a specific mail program, set the mail_client configuration option.
4868
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4869
specific clients are "claws", "evolution", "kmail", "mutt", and
4870
"thunderbird"; generic options are "default", "editor", "emacsclient",
4871
"mapi", and "xdg-email". Plugins may also add supported clients.
4873
If mail is being sent, a to address is required. This can be supplied
4874
either on the commandline, by setting the submit_to configuration
4875
option in the branch itself or the child_submit_to configuration option
4876
in the submit branch.
4878
Two formats are currently supported: "4" uses revision bundle format 4 and
4879
merge directive format 2. It is significantly faster and smaller than
4880
older formats. It is compatible with Bazaar 0.19 and later. It is the
