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

1951
bzr log http://server/branch log a branch on a server
1953
The filtering, ordering and information shown for each revision can
1954
be controlled as explained below. By default, all revisions are
1955
shown sorted (topologically) so that newer revisions appear before
1956
older ones and descendants always appear before ancestors. If displayed,
1957
merged revisions are shown indented under the revision in which they
1962
The log format controls how information about each revision is
1963
displayed. The standard log formats are called ``long``, ``short``
1964
and ``line``. The default is long. See ``bzr help log-formats``
1965
for more details on log formats.
1967
The following options can be used to control what information is
1970
-l N display a maximum of N revisions
1971
-n N display N levels of revisions (0 for all, 1 for collapsed)
1972
-v display a status summary (delta) for each revision
1973
-p display a diff (patch) for each revision
1974
--show-ids display revision-ids (and file-ids), not just revnos
1976
Note that the default number of levels to display is a function of the
1977
log format. If the -n option is not used, the standard log formats show
1978
just the top level (mainline).
1980
Status summaries are shown using status flags like A, M, etc. To see
1981
the changes explained using words like ``added`` and ``modified``
1982
instead, use the -vv option.
1986
To display revisions from oldest to newest, use the --forward option.
1987
In most cases, using this option will have little impact on the total
1988
time taken to produce a log, though --forward does not incrementally
1989
display revisions like --reverse does when it can.

1994
to filter against. The various forms are shown below::

-rX display revision X
1997
-rX.. display revision X and later
1998
-r..Y display up to and including revision Y
1999
-rX..Y display from X to Y inclusive
2001
See ``bzr help revisionspec`` for details on how to specify X and Y.
2002
Some common examples are given below::
2004
-r-1 show just the tip
2005
-r-10.. show the last 10 mainline revisions
2006
-rsubmit:.. show what's new on this branch
2007
-rancestor:path.. show changes since the common ancestor of this
2008
branch and the one at location path
2009
-rdate:yesterday.. show changes since yesterday
2011
When logging a range of revisions using -rX..Y, log starts at
2012
revision Y and searches back in history through the primary
2013
("left-hand") parents until it finds X. When logging just the
2014
top level (using -n1), an error is reported if X is not found
2015
along the way. If multi-level logging is used (-n0), X may be
2016
a nested merge revision and the log will be truncated accordingly.
2020
If parameters are given and the first one is not a branch, the log
2021
will be filtered to show only those revisions that changed the
2022
nominated files or directories.
2024
Filenames are interpreted within their historical context. To log a
2025
deleted file, specify a revision range so that the file existed at
2026
the end or start of the range.
2028
Historical context is also important when interpreting pathnames of
2029
renamed files/directories. Consider the following example:
2031
* revision 1: add tutorial.txt
2032
* revision 2: modify tutorial.txt
2033
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2037
* ``bzr log guide.txt`` will log the file added in revision 1
2039
* ``bzr log tutorial.txt`` will log the new file added in revision 3
2041
* ``bzr log -r2 -p tutorial.txt`` will show the changes made to
2042
the original file in revision 2.
2044
* ``bzr log -r2 -p guide.txt`` will display an error message as there
2045
was no file called guide.txt in revision 2.
2047
Renames are always followed by log. By design, there is no need to
2048
explicitly ask for this (and no way to stop logging a file back
2049
until it was last renamed).
2053
The --message option can be used for finding revisions that match a
2054
regular expression in a commit message.
2058
GUI tools and IDEs are often better at exploring history than command
2059
line tools. You may prefer qlog or glog from the QBzr and Bzr-Gtk packages
2060
respectively for example. (TortoiseBzr uses qlog for displaying logs.) See
2061
http://bazaar-vcs.org/BzrPlugins and http://bazaar-vcs.org/IDEIntegration.
2063
Web interfaces are often better at exploring history than command line
2064
tools, particularly for branches on servers. You may prefer Loggerhead
2065
or one of its alternatives. See http://bazaar-vcs.org/WebInterface.
2067
You may find it useful to add the aliases below to ``bazaar.conf``::
2071
top = log -l10 --line
2074
``bzr tip`` will then show the latest revision while ``bzr top``
2075
will show the last 10 mainline revisions. To see the details of a
2076
particular revision X, ``bzr show -rX``.
2078
If you are interested in looking deeper into a particular merge X,
2079
use ``bzr log -n0 -rX``.
2081
``bzr log -v`` on a branch with lots of history is currently
2082
very slow. A fix for this issue is currently under development.
2083
With or without that fix, it is recommended that a revision range
2084
be given when using the -v option.
2086
bzr has a generic full-text matching plugin, bzr-search, that can be
2087
used to find revisions matching user names, commit messages, etc.
2088
Among other features, this plugin can find all revisions containing
2089
a list of words but not others.
2091
When exploring non-mainline history on large projects with deep
2092
history, the performance of log can be greatly improved by installing
2093
the historycache plugin. This plugin buffers historical information
2094
trading disk space for faster speed.

"""Commit changes into a new revision.
2732
An explanatory message needs to be given for each commit. This is
2733
often done by using the --message option (getting the message from the
2734
command line) or by using the --file option (getting the message from
2735
a file). If neither of these options is given, an editor is opened for
2736
the user to enter the message. To see the changed files in the
2737
boilerplate text loaded into the editor, use the --show-diff option.
2739
By default, the entire tree is committed and the person doing the
2740
commit is assumed to be the author. These defaults can be overridden
2745
If selected files are specified, only changes to those files are
2746
committed. If a directory is specified then the directory and
2747
everything within it is committed.
2749
When excludes are given, they take precedence over selected files.
2750
For example, to commit only changes within foo, but not changes
2753
bzr commit foo -x foo/bar
2755
A selective commit after a merge is not yet supported.
2759
If the author of the change is not the same person as the committer,
2760
you can specify the author's name using the --author option. The
2761
name should be in the same format as a committer-id, e.g.
2762
"John Doe <jdoe@example.com>". If there is more than one author of
2763
the change you can specify the option multiple times, once for each
2768
A common mistake is to forget to add a new file or directory before
2769
running the commit command. The --strict option checks for unknown
2770
files and aborts the commit if any are found. More advanced pre-commit
2771
checks can be implemented by defining hooks. See ``bzr help hooks``
2776
If you accidentially commit the wrong changes or make a spelling
2777
mistake in the commit message say, you can use the uncommit command
2778
to undo it. See ``bzr help uncommit`` for details.
2780
Hooks can also be configured to run after a commit. This allows you
2781
to trigger updates to external systems like bug trackers. The --fixes
2782
option can be used to record the association between a revision and
2783
one or more bugs. See ``bzr help bugs`` for details.
2785
A selective commit may fail in some cases where the committed
2786
tree would be invalid. Consider::
2791
bzr commit foo -m "committing foo"
2792
bzr mv foo/bar foo/baz
2795
bzr commit foo/bar -m "committing bar but not baz"
2797
In the example above, the last commit will fail by design. This gives
2798
the user the opportunity to decide whether they want to commit the
2799
rename at the same time, separately first, or not at all. (As a general
2800
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,
3424
or in the form of a path to a file containing a merge directive generated
3425
with bzr send. If neither is specified, the default is the upstream branch
3426
or the branch most recently merged using --remember.
3428
When merging a branch, by default the tip will be merged. To pick a different
3429
revision, pass --revision. If you specify two values, the first will be used as
3430
BASE and the second one as OTHER. Merging individual revisions, or a subset of
3431
available revisions, like this is commonly referred to as "cherrypicking".
3433
Revision numbers are always relative to the branch being merged.
3435
By default, bzr will try to merge in all new work from the other
3436
branch, automatically determining an appropriate base. If this
3437
fails, you may need to give an explicit base.
3439
Merge will do its best to combine the changes in two branches, but there
3440
are some kinds of problems only a human can fix. When it encounters those,
3441
it will mark a conflict. A conflict means that you need to fix something,
3442
before you should commit.
3444
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
3446
If there is no default branch set, the first merge will set it. After
3447
that, you can omit the branch to use the default. To change the
3448
default, use --remember. The value will only be saved if the remote
3449
location can be accessed.
3451
The results of the merge are placed into the destination working
3452
directory, where they can be reviewed (with bzr diff), tested, and then

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

information necessary to do so. This means it must either include a
4676
revision bundle, or the location of a branch containing the desired
4679
A submit branch (the location to merge into) must be supplied the first
4680
time the command is issued. After it has been supplied once, it will
4681
be remembered as the default.
4683
A public branch is optional if a revision bundle is supplied, but required
4684
if --diff or --plain is specified. It will be remembered as the default
4685
after the first use.

A merge directive provides many things needed for requesting merges:
4775
* A machine-readable description of the merge to perform
4777
* An optional patch that is a preview of the changes requested
4779
* An optional bundle of revision data, so that the changes can be applied
4780
directly from the merge directive, without retrieving data from a
4783
If --no-bundle is specified, then public_branch is needed (and must be
4784
up-to-date), so that the receiver can perform the merge using the
4785
public_branch. The public_branch is always included if known, so that
4786
people can check it later.
4788
The submit branch defaults to the parent, but can be overridden. Both
4789
submit branch and public branch will be remembered if supplied.
4791
If a public_branch is known for the submit_branch, that public submit
4792
branch is used in the merge instructions. This means that a local mirror
4793
can be used as your actual submit branch, once you have set public_branch
4796
Mail is sent using your preferred mail program. This should be transparent
4797
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4798
If the preferred client can't be found (or used), your editor will be used.
4800
To use a specific mail program, set the mail_client configuration option.
4801
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4802
specific clients are "claws", "evolution", "kmail", "mutt", and
4803
"thunderbird"; generic options are "default", "editor", "emacsclient",
4804
"mapi", and "xdg-email". Plugins may also add supported clients.
4806
If mail is being sent, a to address is required. This can be supplied
4807
either on the commandline, by setting the submit_to configuration
4808
option in the branch itself or the child_submit_to configuration option
4809
in the submit branch.
4811
Two formats are currently supported: "4" uses revision bundle format 4 and
4812
merge directive format 2. It is significantly faster and smaller than
4813
older formats. It is compatible with Bazaar 0.19 and later. It is the
4814
default. "0.9" uses revision bundle format 0.9 and merge directive
4815
format 1. It is compatible with Bazaar 0.12 - 0.18.
