log is bzr's default tool for exploring the history of a branch.

are given, the branch containing the working directory is logged.
1925
Here are some simple examples::
1927
bzr log log the current branch
1928
bzr log foo.py log a file in its branch
1929
bzr log http://server/branch log a branch on a server
1931
The filtering, ordering and information shown for each revision can
1932
be controlled as explained below. By default, all revisions are
1933
shown sorted (topologically) so that newer revisions appear before
1934
older ones and descendants always appear before ancestors. If displayed,
1935
merged revisions are shown indented under the revision in which they
1940
The log format controls how information about each revision is
1941
displayed. The standard log formats are called ``long``, ``short``
1942
and ``line``. The default is long. See ``bzr help log-formats``
1943
for more details on log formats.
1945
The following options can be used to control what information is
1948
-l N display a maximum of N revisions
1949
-n N display N levels of revisions (0 for all, 1 for collapsed)
1950
-v display a status summary (delta) for each revision
1951
-p display a diff (patch) for each revision
1952
--show-ids display revision-ids (and file-ids), not just revnos
1954
Note that the default number of levels to display is a function of the
1955
log format. If the -n option is not used, ``short`` and ``line`` show
1956
just the top level (mainline) while ``long`` shows all levels of merged
1959
Status summaries are shown using status flags like A, M, etc. To see
1960
the changes explained using words like ``added`` and ``modified``
1961
instead, use the -vv option.
1965
To display revisions from oldest to newest, use the --forward option.
1966
In most cases, using this option will have little impact on the total
1967
time taken to produce a log, though --forward does not incrementally
1968
display revisions like --reverse does when it can.
1970
:Revision filtering:
1972
The -r option can be used to specify what revision or range of revisions
1973
to filter against. The various forms are shown below::
1975
-rX display revision X
1976
-rX.. display revision X and later
1977
-r..Y display up to and including revision Y
1978
-rX..Y display from X to Y inclusive
1980
See ``bzr help revisionspec`` for details on how to specify X and Y.
1981
Some common examples are given below::
1983
-r-1 show just the tip
1984
-r-10.. show the last 10 mainline revisions
1985
-rsubmit:.. show what's new on this branch
1986
-rancestor:path.. show changes since the common ancestor of this
1987
branch and the one at location path
1988
-rdate:yesterday.. show changes since yesterday
1990
When logging a range of revisions using -rX..Y, log starts at
1991
revision Y and searches back in history through the primary
1992
("left-hand") parents until it finds X. When logging just the
1993
top level (using -n1), an error is reported if X is not found
1994
along the way. If multi-level logging is used (-n0), X may be
1995
a nested merge revision and the log will be truncated accordingly.
1999
If a parameter is given and it's not a branch, the log will be filtered
2000
to show only those revisions that changed the nominated file or
2003
Filenames are interpreted within their historical context. To log a
2004
deleted file, specify a revision range so that the file existed at
2005
the end or start of the range.
2007
Historical context is also important when interpreting pathnames of
2008
renamed files/directories. Consider the following example:
2010
* revision 1: add tutorial.txt
2011
* revision 2: modify tutorial.txt
2012
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2016
* ``bzr log guide.txt`` will log the file added in revision 1
2018
* ``bzr log tutorial.txt`` will log the new file added in revision 3
2020
* ``bzr log -r2 -p tutorial.txt`` will show the changes made to
2021
the original file in revision 2.
2023
* ``bzr log -r2 -p guide.txt`` will display an error message as there
2024
was no file called guide.txt in revision 2.
2026
Renames are always followed by log. By design, there is no need to
2027
explicitly ask for this (and no way to stop logging a file back
2028
until it was last renamed).
2030
Note: If the path is a directory, only revisions that directly changed
2031
that directory object are currently shown. This is considered a bug.
2032
(Support for filtering against multiple files and for files within a
2033
directory is under development.)
2037
The --message option can be used for finding revisions that match a
2038
regular expression in a commit message.
2042
GUI tools and IDEs are often better at exploring history than command
2043
line tools. You may prefer qlog or glog from the QBzr and Bzr-Gtk packages
2044
respectively for example. (TortoiseBzr uses qlog for displaying logs.) See
2045
http://bazaar-vcs.org/BzrPlugins and http://bazaar-vcs.org/IDEIntegration.
2047
Web interfaces are often better at exploring history than command line
2048
tools, particularly for branches on servers. You may prefer Loggerhead
2049
or one of its alternatives. See http://bazaar-vcs.org/WebInterface.
2051
You may find it useful to add the aliases below to ``bazaar.conf``::
2055
top = log -r-10.. --short --forward
2056
show = log -v -p -n1 --long
2058
``bzr tip`` will then show the latest revision while ``bzr top``
2059
will show the last 10 mainline revisions. To see the details of a
2060
particular revision X, ``bzr show -rX``.
2062
As many GUI tools and Web interfaces do, you may prefer viewing
2063
history collapsed initially. If you are interested in looking deeper
2064
into a particular merge X, use ``bzr log -n0 -rX``. If you like
2065
working this way, you may wish to either:
2067
* change your default log format to short (or line)
2068
* add this alias: log = log -n1
2070
``bzr log -v`` on a branch with lots of history is currently
2071
very slow. A fix for this issue is currently under development.
2072
With or without that fix, it is recommended that a revision range
2073
be given when using the -v option.
2075
bzr has a generic full-text matching plugin, bzr-search, that can be
2076
used to find revisions matching user names, commit messages, etc.
2077
Among other features, this plugin can find all revisions containing
2078
a list of words but not others.
2080
When exploring non-mainline history on large projects with deep
2081
history, the performance of log can be greatly improved by installing
2082
the revnocache plugin. This plugin buffers historical information
2083
trading disk space for faster speed.

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
3337
with bzr send. If neither is specified, the default is the upstream branch
3338
or the branch most recently merged using --remember.
3340
When merging a branch, by default the tip will be merged. To pick a different
3341
revision, pass --revision. If you specify two values, the first will be used as
3342
BASE and the second one as OTHER. Merging individual revisions, or a subset of
3343
available revisions, like this is commonly referred to as "cherrypicking".
3345
Revision numbers are always relative to the branch being merged.
3347
By default, bzr will try to merge in all new work from the other
3348
branch, automatically determining an appropriate base. If this
3349
fails, you may need to give an explicit base.
3351
Merge will do its best to combine the changes in two branches, but there
3352
are some kinds of problems only a human can fix. When it encounters those,
3353
it will mark a conflict. A conflict means that you need to fix something,
3354
before you should commit.
3356
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
3358
If there is no default branch set, the first merge will set it. After
3359
that, you can omit the branch to use the default. To change the
3360
default, use --remember. The value will only be saved if the remote
3361
location can be accessed.
3363
The results of the merge are placed into the destination working
3364
directory, where they can be reviewed (with bzr diff), tested, and then
3365

3751
To remove only some changes, without reverting to a prior version, use

merge instead. For example, "merge . --revision -2..-3" will remove the

changes introduced by -2, without affecting the changes introduced by -1.

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

"""Mail or create a merge-directive for submitting changes.
4733
A merge directive provides many things needed for requesting merges:
4735
* A machine-readable description of the merge to perform
4737
* An optional patch that is a preview of the changes requested
4739
* An optional bundle of revision data, so that the changes can be applied
4740
directly from the merge directive, without retrieving data from a
4743
If --no-bundle is specified, then public_branch is needed (and must be
4744
up-to-date), so that the receiver can perform the merge using the
4745
public_branch. The public_branch is always included if known, so that
4746
people can check it later.
4748
The submit branch defaults to the parent, but can be overridden. Both
4749
submit branch and public branch will be remembered if supplied.
4751
If a public_branch is known for the submit_branch, that public submit
4752
branch is used in the merge instructions. This means that a local mirror
4753
can be used as your actual submit branch, once you have set public_branch
4756
Mail is sent using your preferred mail program. This should be transparent
4757
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4758
If the preferred client can't be found (or used), your editor will be used.
4760
To use a specific mail program, set the mail_client configuration option.
4761
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4762
specific clients are "claws", "evolution", "kmail", "mutt", and
4763
"thunderbird"; generic options are "default", "editor", "emacsclient",
4764
"mapi", and "xdg-email". Plugins may also add supported clients.
4766
If mail is being sent, a to address is required. This can be supplied
4767
either on the commandline, by setting the submit_to configuration
4768
option in the branch itself or the child_submit_to configuration option
4769
in the submit branch.
4771
Two formats are currently supported: "4" uses revision bundle format 4 and
4772
merge directive format 2. It is significantly faster and smaller than
4773
older formats. It is compatible with Bazaar 0.19 and later. It is the
4774
default. "0.9" uses revision bundle format 0.9 and merge directive
4775
format 1. It is compatible with Bazaar 0.12 - 0.18.
4777
The merge directives created by bzr send may be applied using bzr merge or
4778
bzr pull by specifying a file containing a merge directive as the location.
