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

1950
bzr log http://server/branch log a branch on a server
1952
The filtering, ordering and information shown for each revision can
1953
be controlled as explained below. By default, all revisions are
1954
shown sorted (topologically) so that newer revisions appear before
1955
older ones and descendants always appear before ancestors. If displayed,
1956
merged revisions are shown indented under the revision in which they
1961
The log format controls how information about each revision is
1962
displayed. The standard log formats are called ``long``, ``short``
1963
and ``line``. The default is long. See ``bzr help log-formats``
1964
for more details on log formats.
1966
The following options can be used to control what information is
1969
-l N display a maximum of N revisions
1970
-n N display N levels of revisions (0 for all, 1 for collapsed)
1971
-v display a status summary (delta) for each revision
1972
-p display a diff (patch) for each revision
1973
--show-ids display revision-ids (and file-ids), not just revnos
1975
Note that the default number of levels to display is a function of the
1976
log format. If the -n option is not used, the standard log formats show
1977
just the top level (mainline).
1979
Status summaries are shown using status flags like A, M, etc. To see
1980
the changes explained using words like ``added`` and ``modified``
1981
instead, use the -vv option.
1985
To display revisions from oldest to newest, use the --forward option.
1986
In most cases, using this option will have little impact on the total
1987
time taken to produce a log, though --forward does not incrementally
1988
display revisions like --reverse does when it can.
1990
:Revision filtering:
1992
The -r option can be used to specify what revision or range of revisions
1993
to filter against. The various forms are shown below::
1995
-rX display revision X
1996
-rX.. display revision X and later
1997
-r..Y display up to and including revision Y
1998
-rX..Y display from X to Y inclusive
2000
See ``bzr help revisionspec`` for details on how to specify X and Y.
2001
Some common examples are given below::
2003
-r-1 show just the tip
2004
-r-10.. show the last 10 mainline revisions
2005
-rsubmit:.. show what's new on this branch
2006
-rancestor:path.. show changes since the common ancestor of this
2007
branch and the one at location path
2008
-rdate:yesterday.. show changes since yesterday
2010
When logging a range of revisions using -rX..Y, log starts at
2011
revision Y and searches back in history through the primary
2012
("left-hand") parents until it finds X. When logging just the
2013
top level (using -n1), an error is reported if X is not found
2014
along the way. If multi-level logging is used (-n0), X may be
2015
a nested merge revision and the log will be truncated accordingly.
2019
If parameters are given and the first one is not a branch, the log
2020
will be filtered to show only those revisions that changed the
2021
nominated files or directories.
2023
Filenames are interpreted within their historical context. To log a
2024
deleted file, specify a revision range so that the file existed at
2025
the end or start of the range.
2027
Historical context is also important when interpreting pathnames of
2028
renamed files/directories. Consider the following example:
2030
* revision 1: add tutorial.txt
2031
* revision 2: modify tutorial.txt
2032
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2036
* ``bzr log guide.txt`` will log the file added in revision 1
2038
* ``bzr log tutorial.txt`` will log the new file added in revision 3
2040
* ``bzr log -r2 -p tutorial.txt`` will show the changes made to
2041
the original file in revision 2.
2043
* ``bzr log -r2 -p guide.txt`` will display an error message as there
2044
was no file called guide.txt in revision 2.
2046
Renames are always followed by log. By design, there is no need to
2047
explicitly ask for this (and no way to stop logging a file back
2048
until it was last renamed).
2052
The --message option can be used for finding revisions that match a
2053
regular expression in a commit message.
2057
GUI tools and IDEs are often better at exploring history than command
2058
line tools. You may prefer qlog or glog from the QBzr and Bzr-Gtk packages
2059
respectively for example. (TortoiseBzr uses qlog for displaying logs.) See
2060
http://bazaar-vcs.org/BzrPlugins and http://bazaar-vcs.org/IDEIntegration.
2062
Web interfaces are often better at exploring history than command line
2063
tools, particularly for branches on servers. You may prefer Loggerhead
2064
or one of its alternatives. See http://bazaar-vcs.org/WebInterface.
2066
You may find it useful to add the aliases below to ``bazaar.conf``::
2070
top = log -l10 --line
2073
``bzr tip`` will then show the latest revision while ``bzr top``
2074
will show the last 10 mainline revisions. To see the details of a
2075
particular revision X, ``bzr show -rX``.
2077
If you are interested in looking deeper into a particular merge X,
2078
use ``bzr log -n0 -rX``.
2080
``bzr log -v`` on a branch with lots of history is currently
2081
very slow. A fix for this issue is currently under development.
2082
With or without that fix, it is recommended that a revision range
2083
be given when using the -v option.
2085
bzr has a generic full-text matching plugin, bzr-search, that can be
2086
used to find revisions matching user names, commit messages, etc.
2087
Among other features, this plugin can find all revisions containing
2088
a list of words but not others.
2090
When exploring non-mainline history on large projects with deep
2091
history, the performance of log can be greatly improved by installing
2092
the historycache plugin. This plugin buffers historical information
2093
trading disk space for faster speed.

commit is assumed to be the author. These defaults can be overridden
2695
If selected files are specified, only changes to those files are
2696
committed. If a directory is specified then the directory and
2697
everything within it is committed.
2699
When excludes are given, they take precedence over selected files.
2700
For example, to commit only changes within foo, but not changes
2703
bzr commit foo -x foo/bar
2705
A selective commit after a merge is not yet supported.
2709
If the author of the change is not the same person as the committer,
2710
you can specify the author's name using the --author option. The
2711
name should be in the same format as a committer-id, e.g.
2712
"John Doe <jdoe@example.com>". If there is more than one author of
2713
the change you can specify the option multiple times, once for each
2718
A common mistake is to forget to add a new file or directory before
2719
running the commit command. The --strict option checks for unknown
2720
files and aborts the commit if any are found. More advanced pre-commit
2721
checks can be implemented by defining hooks. See ``bzr help hooks``
2726
If you accidentially commit the wrong changes or make a spelling
2727
mistake in the commit message say, you can use the uncommit command
2728
to undo it. See ``bzr help uncommit`` for details.
2730
Hooks can also be configured to run after a commit. This allows you
2731
to trigger updates to external systems like bug trackers. The --fixes
2732
option can be used to record the association between a revision and
2733
one or more bugs. See ``bzr help bugs`` for details.
2735
A selective commit may fail in some cases where the committed
2736
tree would be invalid. Consider::
2741
bzr commit foo -m "committing foo"
2742
bzr mv foo/bar foo/baz
2745
bzr commit foo/bar -m "committing bar but not baz"
2747
In the example above, the last commit will fail by design. This gives
2748
the user the opportunity to decide whether they want to commit the
2749
rename at the same time, separately first, or not at all. (As a general
2750
rule, when in doubt, Bazaar has a policy of Doing the Safe Thing.)

"""Perform a three-way merge.
3373
The source of the merge can be specified either in the form of a branch,
3374
or in the form of a path to a file containing a merge directive generated
3375
with bzr send. If neither is specified, the default is the upstream branch
3376
or the branch most recently merged using --remember.
3378
When merging a branch, by default the tip will be merged. To pick a different
3379
revision, pass --revision. If you specify two values, the first will be used as
3380
BASE and the second one as OTHER. Merging individual revisions, or a subset of
3381
available revisions, like this is commonly referred to as "cherrypicking".
3383
Revision numbers are always relative to the branch being merged.
3385
By default, bzr will try to merge in all new work from the other
3386
branch, automatically determining an appropriate base. If this
3387
fails, you may need to give an explicit base.
3389
Merge will do its best to combine the changes in two branches, but there
3390
are some kinds of problems only a human can fix. When it encounters those,
3391
it will mark a conflict. A conflict means that you need to fix something,
3392
before you should commit.
3394
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
3396
If there is no default branch set, the first merge will set it. After
3397
that, you can omit the branch to use the default. To change the
3398
default, use --remember. The value will only be saved if the remote
3399
location can be accessed.
3401
The results of the merge are placed into the destination working
3402
directory, where they can be reviewed (with bzr diff), tested, and then
3403
committed to record the result of the merge.

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

leaves the pending merge list alone and reverts only the files. Use "bzr

"""Mail or create a merge-directive for submitting changes.
4763
A merge directive provides many things needed for requesting merges:
4765
* A machine-readable description of the merge to perform
4767
* An optional patch that is a preview of the changes requested
4769
* An optional bundle of revision data, so that the changes can be applied
4770
directly from the merge directive, without retrieving data from a
4773
If --no-bundle is specified, then public_branch is needed (and must be
4774
up-to-date), so that the receiver can perform the merge using the
4775
public_branch. The public_branch is always included if known, so that
4776
people can check it later.
4778
The submit branch defaults to the parent, but can be overridden. Both
4779
submit branch and public branch will be remembered if supplied.
4781
If a public_branch is known for the submit_branch, that public submit
4782
branch is used in the merge instructions. This means that a local mirror
4783
can be used as your actual submit branch, once you have set public_branch
4786
Mail is sent using your preferred mail program. This should be transparent
4787
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4788
If the preferred client can't be found (or used), your editor will be used.
4790
To use a specific mail program, set the mail_client configuration option.
4791
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4792
specific clients are "claws", "evolution", "kmail", "mutt", and
4793
"thunderbird"; generic options are "default", "editor", "emacsclient",
4794
"mapi", and "xdg-email". Plugins may also add supported clients.
4796
If mail is being sent, a to address is required. This can be supplied
4797
either on the commandline, by setting the submit_to configuration
4798
option in the branch itself or the child_submit_to configuration option
4799
in the submit branch.
4801
Two formats are currently supported: "4" uses revision bundle format 4 and
4802
merge directive format 2. It is significantly faster and smaller than
4803
older formats. It is compatible with Bazaar 0.19 and later. It is the
4804
default. "0.9" uses revision bundle format 0.9 and merge directive
4805
format 1. It is compatible with Bazaar 0.12 - 0.18.
4807
The merge directives created by bzr send may be applied using bzr merge or
4808
bzr pull by specifying a file containing a merge directive as the location.

5298
Views provide a mask over the tree so that users can focus on
5299
a subset of a tree when doing their work. After creating a view,
5300
commands that support a list of files - status, diff, commit, etc -
5301
effectively have that list of files implicitly given each time.
5302
An explicit list of files can still be given but those files
5303
must be within the current view.
5305
In most cases, a view has a short life-span: it is created to make
5306
a selected change and is deleted once that change is committed.
5307
At other times, you may wish to create one or more named views
5308
and switch between them.
5310
To disable the current view without deleting it, you can switch to
5311
the pseudo view called ``off``. This can be useful when you need
5312
to see the whole tree for an operation or two (e.g. merge) but
5313
want to switch back to your view after that.
