2031
log is bzr's default tool for exploring the history of a branch.
2032
The branch to use is taken from the first parameter. If no parameters
2033
are given, the branch containing the working directory is logged.
2034
Here are some simple examples::
2036
bzr log log the current branch
2037
bzr log foo.py log a file in its branch
2038
bzr log http://server/branch log a branch on a server
2040
The filtering, ordering and information shown for each revision can
2041
be controlled as explained below. By default, all revisions are
2042
shown sorted (topologically) so that newer revisions appear before
2043
older ones and descendants always appear before ancestors. If displayed,
2044
merged revisions are shown indented under the revision in which they
2049
The log format controls how information about each revision is
2050
displayed. The standard log formats are called ``long``, ``short``
2051
and ``line``. The default is long. See ``bzr help log-formats``
2052
for more details on log formats.
2054
The following options can be used to control what information is
2057
-l N display a maximum of N revisions
2058
-n N display N levels of revisions (0 for all, 1 for collapsed)
2059
-v display a status summary (delta) for each revision
2060
-p display a diff (patch) for each revision
2061
--show-ids display revision-ids (and file-ids), not just revnos
2063
Note that the default number of levels to display is a function of the
2064
log format. If the -n option is not used, the standard log formats show
2065
just the top level (mainline).
2067
Status summaries are shown using status flags like A, M, etc. To see
2068
the changes explained using words like ``added`` and ``modified``
2069
instead, use the -vv option.
2073
To display revisions from oldest to newest, use the --forward option.
2074
In most cases, using this option will have little impact on the total
2075
time taken to produce a log, though --forward does not incrementally
2076
display revisions like --reverse does when it can.
2078
:Revision filtering:
2080
The -r option can be used to specify what revision or range of revisions
2081
to filter against. The various forms are shown below::
2083
-rX display revision X
2084
-rX.. display revision X and later
2085
-r..Y display up to and including revision Y
2086
-rX..Y display from X to Y inclusive
2088
See ``bzr help revisionspec`` for details on how to specify X and Y.
2089
Some common examples are given below::
2091
-r-1 show just the tip
2092
-r-10.. show the last 10 mainline revisions
2093
-rsubmit:.. show what's new on this branch
2094
-rancestor:path.. show changes since the common ancestor of this
2095
branch and the one at location path
2096
-rdate:yesterday.. show changes since yesterday
2098
When logging a range of revisions using -rX..Y, log starts at
2099
revision Y and searches back in history through the primary
2100
("left-hand") parents until it finds X. When logging just the
2101
top level (using -n1), an error is reported if X is not found
2102
along the way. If multi-level logging is used (-n0), X may be
2103
a nested merge revision and the log will be truncated accordingly.
2107
If parameters are given and the first one is not a branch, the log
2108
will be filtered to show only those revisions that changed the
2109
nominated files or directories.
2111
Filenames are interpreted within their historical context. To log a
2112
deleted file, specify a revision range so that the file existed at
2113
the end or start of the range.
2115
Historical context is also important when interpreting pathnames of
2116
renamed files/directories. Consider the following example:
2118
* revision 1: add tutorial.txt
2119
* revision 2: modify tutorial.txt
2120
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2124
* ``bzr log guide.txt`` will log the file added in revision 1
2126
* ``bzr log tutorial.txt`` will log the new file added in revision 3
2128
* ``bzr log -r2 -p tutorial.txt`` will show the changes made to
2129
the original file in revision 2.
2131
* ``bzr log -r2 -p guide.txt`` will display an error message as there
2132
was no file called guide.txt in revision 2.
2134
Renames are always followed by log. By design, there is no need to
2135
explicitly ask for this (and no way to stop logging a file back
2136
until it was last renamed).
2140
The --message option can be used for finding revisions that match a
2141
regular expression in a commit message.
2145
GUI tools and IDEs are often better at exploring history than command
2146
line tools. You may prefer qlog or glog from the QBzr and Bzr-Gtk packages
2147
respectively for example. (TortoiseBzr uses qlog for displaying logs.) See
2148
http://bazaar-vcs.org/BzrPlugins and http://bazaar-vcs.org/IDEIntegration.
2150
Web interfaces are often better at exploring history than command line
2151
tools, particularly for branches on servers. You may prefer Loggerhead
2152
or one of its alternatives. See http://bazaar-vcs.org/WebInterface.
2154
You may find it useful to add the aliases below to ``bazaar.conf``::
2158
top = log -l10 --line
2161
``bzr tip`` will then show the latest revision while ``bzr top``
2162
will show the last 10 mainline revisions. To see the details of a
2163
particular revision X, ``bzr show -rX``.
2165
If you are interested in looking deeper into a particular merge X,
2166
use ``bzr log -n0 -rX``.
2168
``bzr log -v`` on a branch with lots of history is currently
2169
very slow. A fix for this issue is currently under development.
2170
With or without that fix, it is recommended that a revision range
2171
be given when using the -v option.
2173
bzr has a generic full-text matching plugin, bzr-search, that can be
2174
used to find revisions matching user names, commit messages, etc.
2175
Among other features, this plugin can find all revisions containing
2176
a list of words but not others.
2178
When exploring non-mainline history on large projects with deep
2179
history, the performance of log can be greatly improved by installing
2180
the historycache plugin. This plugin buffers historical information
2181
trading disk space for faster speed.

"""Commit changes into a new revision.
2827
An explanatory message needs to be given for each commit. This is
2828
often done by using the --message option (getting the message from the
2829
command line) or by using the --file option (getting the message from
2830
a file). If neither of these options is given, an editor is opened for
2831
the user to enter the message. To see the changed files in the
2832
boilerplate text loaded into the editor, use the --show-diff option.
2834
By default, the entire tree is committed and the person doing the
2835
commit is assumed to be the author. These defaults can be overridden
2840
If selected files are specified, only changes to those files are
2841
committed. If a directory is specified then the directory and
2842
everything within it is committed.
2844
When excludes are given, they take precedence over selected files.
2845
For example, to commit only changes within foo, but not changes
2848
bzr commit foo -x foo/bar
2850
A selective commit after a merge is not yet supported.
2854
If the author of the change is not the same person as the committer,
2855
you can specify the author's name using the --author option. The
2856
name should be in the same format as a committer-id, e.g.
2857
"John Doe <jdoe@example.com>". If there is more than one author of
2858
the change you can specify the option multiple times, once for each
2863
A common mistake is to forget to add a new file or directory before
2864
running the commit command. The --strict option checks for unknown
2865
files and aborts the commit if any are found. More advanced pre-commit
2866
checks can be implemented by defining hooks. See ``bzr help hooks``
2871
If you accidentially commit the wrong changes or make a spelling
2872
mistake in the commit message say, you can use the uncommit command
2873
to undo it. See ``bzr help uncommit`` for details.
2875
Hooks can also be configured to run after a commit. This allows you
2876
to trigger updates to external systems like bug trackers. The --fixes
2877
option can be used to record the association between a revision and
2878
one or more bugs. See ``bzr help bugs`` for details.
2880
A selective commit may fail in some cases where the committed
2881
tree would be invalid. Consider::
2886
bzr commit foo -m "committing foo"
2887
bzr mv foo/bar foo/baz
2890
bzr commit foo/bar -m "committing bar but not baz"
2892
In the example above, the last commit will fail by design. This gives
2893
the user the opportunity to decide whether they want to commit the
2894
rename at the same time, separately first, or not at all. (As a general
2895
rule, when in doubt, Bazaar has a policy of Doing the Safe Thing.)
1333
If no arguments are given, the entire tree is committed.
1335
If selected files are specified, only changes to those files are
1336
committed. If a directory is specified then the directory and everything
1337
within it is committed.
1339
A selected-file commit may fail in some cases where the committed
1340
tree would be invalid, such as trying to commit a file in a
1341
newly-added directory that is not itself committed.

3527
The source of the merge can be specified either in the form of a branch,
3528
or in the form of a path to a file containing a merge directive generated
3529
with bzr send. If neither is specified, the default is the upstream branch
3530
or the branch most recently merged using --remember.
3532
When merging a branch, by default the tip will be merged. To pick a different
3533
revision, pass --revision. If you specify two values, the first will be used as
3534
BASE and the second one as OTHER. Merging individual revisions, or a subset of
3535
available revisions, like this is commonly referred to as "cherrypicking".
3537
Revision numbers are always relative to the branch being merged.
3539
By default, bzr will try to merge in all new work from the other
1691
The branch is the branch you will merge from. By default, it will
1692
merge the latest revision. If you specify a revision, that
1693
revision will be merged. If you specify two revisions, the first
1694
will be used as a BASE, and the second one as OTHER. Revision
1695
numbers are always relative to the specified branch.
1697
By default bzr will try to merge in all new work from the other
3540
1698
branch, automatically determining an appropriate base. If this
3541
1699
fails, you may need to give an explicit base.
3543
Merge will do its best to combine the changes in two branches, but there
3544
are some kinds of problems only a human can fix. When it encounters those,
3545
it will mark a conflict. A conflict means that you need to fix something,
3546
before you should commit.
3548
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
3550
If there is no default branch set, the first merge will set it. After
3551
that, you can omit the branch to use the default. To change the
3552
default, use --remember. The value will only be saved if the remote
3553
location can be accessed.
3555
The results of the merge are placed into the destination working
3556
directory, where they can be reviewed (with bzr diff), tested, and then
3557
committed to record the result of the merge.

merge refuses to run if there are any uncommitted changes, unless

Giving a list of files will revert only those files. Otherwise, all files

will be reverted. If the revision is not specified with '--revision', the
3978
last committed revision is used.
3980
To remove only some changes, without reverting to a prior version, use
3981
merge instead. For example, "merge . --revision -2..-3" will remove the
3982
changes introduced by -2, without affecting the changes introduced by -1.
3983
Or to remove certain changes on a hunk-by-hunk basis, see the Shelf plugin.

By default, any files that have been manually changed will be backed up
3986
first. (Files changed only by merge are not backed up.) Backup files have
3987
'.~#~' appended to their name, where # is a number.
3989
When you provide files, you can use their current pathname or the pathname

from the target revision. So you can use revert to "undelete" a file by

The working tree contains a list of pending merged revisions, which will
3999
be included as parents in the next commit. Normally, revert clears that
4000
list as well as reverting the files. If any files are specified, revert
4001
leaves the pending merge list alone and reverts only the files. Use "bzr
4002
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

4927
people can check it later.
4929
The submit branch defaults to the parent, but can be overridden. Both
4930
submit branch and public branch will be remembered if supplied.
4932
If a public_branch is known for the submit_branch, that public submit
4933
branch is used in the merge instructions. This means that a local mirror
4934
can be used as your actual submit branch, once you have set public_branch
4937
Mail is sent using your preferred mail program. This should be transparent
4938
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4939
If the preferred client can't be found (or used), your editor will be used.
4941
To use a specific mail program, set the mail_client configuration option.
4942
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4943
specific clients are "claws", "evolution", "kmail", "mutt", and
4944
"thunderbird"; generic options are "default", "editor", "emacsclient",
4945
"mapi", and "xdg-email". Plugins may also add supported clients.
4947
If mail is being sent, a to address is required. This can be supplied
4948
either on the commandline, by setting the submit_to configuration
4949
option in the branch itself or the child_submit_to configuration option
4950
in the submit branch.

Views provide a mask over the tree so that users can focus on
5406
a subset of a tree when doing their work. After creating a view,

commands that support a list of files - status, diff, commit, etc -
5408
effectively have that list of files implicitly given each time.
5409
An explicit list of files can still be given but those files
5410
must be within the current view.

In most cases, a view has a short life-span: it is created to make
5413
a selected change and is deleted once that change is committed.

At other times, you may wish to create one or more named views
5415
and switch between them.
5417
To disable the current view without deleting it, you can switch to
5418
the pseudo view called ``off``. This can be useful when you need
