match the remote one, use pull --overwrite.

log is bzr's default tool for exploring the history of a branch.
2098
The branch to use is taken from the first parameter. If no parameters
2099
are given, the branch containing the working directory is logged.
2100
Here are some simple examples::
2102
bzr log log the current branch
2103
bzr log foo.py log a file in its branch
2104
bzr log http://server/branch log a branch on a server
2106
The filtering, ordering and information shown for each revision can
2107
be controlled as explained below. By default, all revisions are
2108
shown sorted (topologically) so that newer revisions appear before
2109
older ones and descendants always appear before ancestors. If displayed,
2110
merged revisions are shown indented under the revision in which they
2115
The log format controls how information about each revision is
2116
displayed. The standard log formats are called ``long``, ``short``
2117
and ``line``. The default is long. See ``bzr help log-formats``
2118
for more details on log formats.
2120
The following options can be used to control what information is
2123
-l N display a maximum of N revisions
2124
-n N display N levels of revisions (0 for all, 1 for collapsed)
2125
-v display a status summary (delta) for each revision
2126
-p display a diff (patch) for each revision
2127
--show-ids display revision-ids (and file-ids), not just revnos
2129
Note that the default number of levels to display is a function of the
2130
log format. If the -n option is not used, the standard log formats show
2131
just the top level (mainline).
2133
Status summaries are shown using status flags like A, M, etc. To see
2134
the changes explained using words like ``added`` and ``modified``
2135
instead, use the -vv option.
2139
To display revisions from oldest to newest, use the --forward option.
2140
In most cases, using this option will have little impact on the total
2141
time taken to produce a log, though --forward does not incrementally
2142
display revisions like --reverse does when it can.
2144
:Revision filtering:
2146
The -r option can be used to specify what revision or range of revisions
2147
to filter against. The various forms are shown below::
2149
-rX display revision X
2150
-rX.. display revision X and later
2151
-r..Y display up to and including revision Y
2152
-rX..Y display from X to Y inclusive
2154
See ``bzr help revisionspec`` for details on how to specify X and Y.
2155
Some common examples are given below::
2157
-r-1 show just the tip
2158
-r-10.. show the last 10 mainline revisions
2159
-rsubmit:.. show what's new on this branch
2160
-rancestor:path.. show changes since the common ancestor of this
2161
branch and the one at location path
2162
-rdate:yesterday.. show changes since yesterday
2164
When logging a range of revisions using -rX..Y, log starts at
2165
revision Y and searches back in history through the primary
2166
("left-hand") parents until it finds X. When logging just the
2167
top level (using -n1), an error is reported if X is not found
2168
along the way. If multi-level logging is used (-n0), X may be
2169
a nested merge revision and the log will be truncated accordingly.
2173
If parameters are given and the first one is not a branch, the log
2174
will be filtered to show only those revisions that changed the
2175
nominated files or directories.
2177
Filenames are interpreted within their historical context. To log a
2178
deleted file, specify a revision range so that the file existed at
2179
the end or start of the range.
2181
Historical context is also important when interpreting pathnames of
2182
renamed files/directories. Consider the following example:
2184
* revision 1: add tutorial.txt
2185
* revision 2: modify tutorial.txt
2186
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2190
* ``bzr log guide.txt`` will log the file added in revision 1
2192
* ``bzr log tutorial.txt`` will log the new file added in revision 3
2194
* ``bzr log -r2 -p tutorial.txt`` will show the changes made to
2195
the original file in revision 2.
2197
* ``bzr log -r2 -p guide.txt`` will display an error message as there
2198
was no file called guide.txt in revision 2.
2200
Renames are always followed by log. By design, there is no need to
2201
explicitly ask for this (and no way to stop logging a file back
2202
until it was last renamed).
2206
The --message option can be used for finding revisions that match a
2207
regular expression in a commit message.
2211
GUI tools and IDEs are often better at exploring history than command
2212
line tools: you may prefer qlog or viz from qbzr or bzr-gtk, the
2213
bzr-explorer shell, or the Loggerhead web interface. See the Plugin
2214
Guide <http://doc.bazaar.canonical.com/plugins/en/> and
2215
<http://wiki.bazaar.canonical.com/IDEIntegration>.
2217
You may find it useful to add the aliases below to ``bazaar.conf``::
2221
top = log -l10 --line
2224
``bzr tip`` will then show the latest revision while ``bzr top``
2225
will show the last 10 mainline revisions. To see the details of a
2226
particular revision X, ``bzr show -rX``.
2228
If you are interested in looking deeper into a particular merge X,
2229
use ``bzr log -n0 -rX``.
2231
``bzr log -v`` on a branch with lots of history is currently
2232
very slow. A fix for this issue is currently under development.
2233
With or without that fix, it is recommended that a revision range
2234
be given when using the -v option.
2236
bzr has a generic full-text matching plugin, bzr-search, that can be
2237
used to find revisions matching user names, commit messages, etc.
2238
Among other features, this plugin can find all revisions containing
2239
a list of words but not others.
2241
When exploring non-mainline history on large projects with deep
2242
history, the performance of log can be greatly improved by installing
2243
the historycache plugin. This plugin buffers historical information
2244
trading disk space for faster speed.

2937
An explanatory message needs to be given for each commit. This is
2938
often done by using the --message option (getting the message from the
2939
command line) or by using the --file option (getting the message from
2940
a file). If neither of these options is given, an editor is opened for
2941
the user to enter the message. To see the changed files in the
2942
boilerplate text loaded into the editor, use the --show-diff option.
2944
By default, the entire tree is committed and the person doing the
2945
commit is assumed to be the author. These defaults can be overridden
2950
If selected files are specified, only changes to those files are
2951
committed. If a directory is specified then the directory and
2952
everything within it is committed.
2954
When excludes are given, they take precedence over selected files.
2955
For example, to commit only changes within foo, but not changes
2958
bzr commit foo -x foo/bar
2960
A selective commit after a merge is not yet supported.
2964
If the author of the change is not the same person as the committer,
2965
you can specify the author's name using the --author option. The
2966
name should be in the same format as a committer-id, e.g.
2967
"John Doe <jdoe@example.com>". If there is more than one author of
2968
the change you can specify the option multiple times, once for each
2973
A common mistake is to forget to add a new file or directory before
2974
running the commit command. The --strict option checks for unknown
2975
files and aborts the commit if any are found. More advanced pre-commit
2976
checks can be implemented by defining hooks. See ``bzr help hooks``
2981
If you accidentially commit the wrong changes or make a spelling
2982
mistake in the commit message say, you can use the uncommit command
2983
to undo it. See ``bzr help uncommit`` for details.
2985
Hooks can also be configured to run after a commit. This allows you
2986
to trigger updates to external systems like bug trackers. The --fixes
2987
option can be used to record the association between a revision and
2988
one or more bugs. See ``bzr help bugs`` for details.
2990
A selective commit may fail in some cases where the committed
2991
tree would be invalid. Consider::
2996
bzr commit foo -m "committing foo"
2997
bzr mv foo/bar foo/baz
3000
bzr commit foo/bar -m "committing bar but not baz"
3002
In the example above, the last commit will fail by design. This gives
3003
the user the opportunity to decide whether they want to commit the
3004
rename at the same time, separately first, or not at all. (As a general
3005
rule, when in doubt, Bazaar has a policy of Doing the Safe Thing.)
