The filtering, ordering and information shown for each revision can
2127
be controlled as explained below. By default, all revisions are
2128
shown sorted (topologically) so that newer revisions appear before
2129
older ones and descendants always appear before ancestors. If displayed,
2130
merged revisions are shown indented under the revision in which they
2135
The log format controls how information about each revision is
2136
displayed. The standard log formats are called ``long``, ``short``
2137
and ``line``. The default is long. See ``bzr help log-formats``
2138
for more details on log formats.
2140
The following options can be used to control what information is
2143
-l N display a maximum of N revisions
2144
-n N display N levels of revisions (0 for all, 1 for collapsed)
2145
-v display a status summary (delta) for each revision
2146
-p display a diff (patch) for each revision
2147
--show-ids display revision-ids (and file-ids), not just revnos
2149
Note that the default number of levels to display is a function of the
2150
log format. If the -n option is not used, the standard log formats show
2151
just the top level (mainline).
2153
Status summaries are shown using status flags like A, M, etc. To see
2154
the changes explained using words like ``added`` and ``modified``
2155
instead, use the -vv option.
2159
To display revisions from oldest to newest, use the --forward option.
2160
In most cases, using this option will have little impact on the total
2161
time taken to produce a log, though --forward does not incrementally
2162
display revisions like --reverse does when it can.
2164
:Revision filtering:
2166
The -r option can be used to specify what revision or range of revisions
2167
to filter against. The various forms are shown below::
2169
-rX display revision X
2170
-rX.. display revision X and later
2171
-r..Y display up to and including revision Y
2172
-rX..Y display from X to Y inclusive
2174
See ``bzr help revisionspec`` for details on how to specify X and Y.
2175
Some common examples are given below::
2177
-r-1 show just the tip
2178
-r-10.. show the last 10 mainline revisions
2179
-rsubmit:.. show what's new on this branch
2180
-rancestor:path.. show changes since the common ancestor of this
2181
branch and the one at location path
2182
-rdate:yesterday.. show changes since yesterday
2184
When logging a range of revisions using -rX..Y, log starts at
2185
revision Y and searches back in history through the primary
2186
("left-hand") parents until it finds X. When logging just the
2187
top level (using -n1), an error is reported if X is not found
2188
along the way. If multi-level logging is used (-n0), X may be
2189
a nested merge revision and the log will be truncated accordingly.
2193
If parameters are given and the first one is not a branch, the log
2194
will be filtered to show only those revisions that changed the
2195
nominated files or directories.
2197
Filenames are interpreted within their historical context. To log a
2198
deleted file, specify a revision range so that the file existed at
2199
the end or start of the range.
2201
Historical context is also important when interpreting pathnames of
2202
renamed files/directories. Consider the following example:
2204
* revision 1: add tutorial.txt
2205
* revision 2: modify tutorial.txt
2206
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2210
* ``bzr log guide.txt`` will log the file added in revision 1
2212
* ``bzr log tutorial.txt`` will log the new file added in revision 3
2214
* ``bzr log -r2 -p tutorial.txt`` will show the changes made to
2215
the original file in revision 2.
2217
* ``bzr log -r2 -p guide.txt`` will display an error message as there
2218
was no file called guide.txt in revision 2.
2220
Renames are always followed by log. By design, there is no need to
2221
explicitly ask for this (and no way to stop logging a file back
2222
until it was last renamed).
2226
The --message option can be used for finding revisions that match a
2227
regular expression in a commit message.
2231
GUI tools and IDEs are often better at exploring history than command
2232
line tools: you may prefer qlog or viz from qbzr or bzr-gtk, the
2233
bzr-explorer shell, or the Loggerhead web interface. See the Plugin
2234
Guide <http://doc.bazaar.canonical.com/plugins/en/> and
2235
<http://wiki.bazaar.canonical.com/IDEIntegration>.
2237
You may find it useful to add the aliases below to ``bazaar.conf``::
2241
top = log -l10 --line
2244
``bzr tip`` will then show the latest revision while ``bzr top``
2245
will show the last 10 mainline revisions. To see the details of a
2246
particular revision X, ``bzr show -rX``.
2248
If you are interested in looking deeper into a particular merge X,
2249
use ``bzr log -n0 -rX``.
2251
``bzr log -v`` on a branch with lots of history is currently
2252
very slow. A fix for this issue is currently under development.
2253
With or without that fix, it is recommended that a revision range
2254
be given when using the -v option.
2256
bzr has a generic full-text matching plugin, bzr-search, that can be
2257
used to find revisions matching user names, commit messages, etc.
2258
Among other features, this plugin can find all revisions containing
2259
a list of words but not others.
2261
When exploring non-mainline history on large projects with deep
2262
history, the performance of log can be greatly improved by installing
2263
the historycache plugin. This plugin buffers historical information
2264
trading disk space for faster speed.

By default show the log of the branch containing the working directory.

2964
An explanatory message needs to be given for each commit. This is
2965
often done by using the --message option (getting the message from the
2966
command line) or by using the --file option (getting the message from
2967
a file). If neither of these options is given, an editor is opened for
2968
the user to enter the message. To see the changed files in the
2969
boilerplate text loaded into the editor, use the --show-diff option.
2971
By default, the entire tree is committed and the person doing the
2972
commit is assumed to be the author. These defaults can be overridden
2977
If selected files are specified, only changes to those files are
2978
committed. If a directory is specified then the directory and
2979
everything within it is committed.
2981
When excludes are given, they take precedence over selected files.
2982
For example, to commit only changes within foo, but not changes
2985
bzr commit foo -x foo/bar
2987
A selective commit after a merge is not yet supported.
2991
If the author of the change is not the same person as the committer,
2992
you can specify the author's name using the --author option. The
2993
name should be in the same format as a committer-id, e.g.
2994
"John Doe <jdoe@example.com>". If there is more than one author of
2995
the change you can specify the option multiple times, once for each
3000
A common mistake is to forget to add a new file or directory before
3001
running the commit command. The --strict option checks for unknown
3002
files and aborts the commit if any are found. More advanced pre-commit
3003
checks can be implemented by defining hooks. See ``bzr help hooks``
3008
If you accidentially commit the wrong changes or make a spelling
3009
mistake in the commit message say, you can use the uncommit command
3010
to undo it. See ``bzr help uncommit`` for details.
3012
Hooks can also be configured to run after a commit. This allows you
3013
to trigger updates to external systems like bug trackers. The --fixes
3014
option can be used to record the association between a revision and
3015
one or more bugs. See ``bzr help bugs`` for details.
3017
A selective commit may fail in some cases where the committed
3018
tree would be invalid. Consider::
3023
bzr commit foo -m "committing foo"
3024
bzr mv foo/bar foo/baz
3027
bzr commit foo/bar -m "committing bar but not baz"
3029
In the example above, the last commit will fail by design. This gives
3030
the user the opportunity to decide whether they want to commit the
3031
rename at the same time, separately first, or not at all. (As a general
3032
rule, when in doubt, Bazaar has a policy of Doing the Safe Thing.)

or the branch most recently merged using --remember.
3714
When merging a branch, by default the tip will be merged. To pick a different

revision, pass --revision. If you specify two values, the first will be used as
3716
BASE and the second one as OTHER. Merging individual revisions, or a subset of

4165
Giving a list of files will revert only those files. Otherwise, all files
4166
will be reverted. If the revision is not specified with '--revision', the
4167
last committed revision is used.
4169
To remove only some changes, without reverting to a prior version, use
4170
merge instead. For example, "merge . --revision -2..-3" will remove the
4171
changes introduced by -2, without affecting the changes introduced by -1.
4172
Or to remove certain changes on a hunk-by-hunk basis, see the Shelf plugin.
4174
By default, any files that have been manually changed will be backed up
4175
first. (Files changed only by merge are not backed up.) Backup files have
4176
'.~#~' appended to their name, where # is a number.
4178
When you provide files, you can use their current pathname or the pathname
4179
from the target revision. So you can use revert to "undelete" a file by
4180
name. If you name a directory, all the contents of that directory will be
4183
If you have newly added files since the target revision, they will be
4184
removed. If the files to be removed have been changed, backups will be
4185

4188
The working tree contains a list of revisions that have been merged but
4189
not yet committed. These revisions will be included as additional parents
4190
of the next commit. Normally, using revert clears that list as well as
4191
reverting the files. If any files are specified, revert leaves the list
4192
of uncommitted merges alone and reverts only the files. Use ``bzr revert
4193
.`` in the tree root to revert all files but keep the recorded merges,
4194
and ``bzr revert --forget-merges`` to clear the pending merge list without
4195
reverting any files.
4197
Using "bzr revert --forget-merges", it is possible to apply all of the
4198
changes from a branch in a single revision. To do this, perform the merge
4199
as desired. Then doing revert with the "--forget-merges" option will keep
4200
the content of the tree as it was, but it will clear the list of pending
4201
merges. The next commit will then contain all of the changes that are
4202
present in the other branch, but without any other parent revisions.

5127
A merge directive provides many things needed for requesting merges:
5129
* A machine-readable description of the merge to perform
5131
* An optional patch that is a preview of the changes requested
5133
* An optional bundle of revision data, so that the changes can be applied
5134
directly from the merge directive, without retrieving data from a
5137
`bzr send` creates a compact data set that, when applied using bzr
5138
merge, has the same effect as merging from the source branch.
5140
By default the merge directive is self-contained and can be applied to any
5141
branch containing submit_branch in its ancestory without needing access to
5144
If --no-bundle is specified, then Bazaar doesn't send the contents of the
5145
revisions, but only a structured request to merge from the
5146
public_location. In that case the public_branch is needed and it must be
5147
up-to-date and accessible to the recipient. The public_branch is always
5148
included if known, so that people can check it later.
5150
The submit branch defaults to the parent of the source branch, but can be
5151
overridden. Both submit branch and public branch will be remembered in
5152
branch.conf the first time they are used for a particular branch. The
5153
source branch defaults to that containing the working directory, but can
5154
be changed using --from.
5156
In order to calculate those changes, bzr must analyse the submit branch.
5157
Therefore it is most efficient for the submit branch to be a local mirror.
5158
If a public location is known for the submit_branch, that location is used
5159
in the merge directive.
5161
The default behaviour is to send the merge directive by mail, unless -o is
5162
given, in which case it is sent to a file.
5164
Mail is sent using your preferred mail program. This should be transparent
5165
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
5166
If the preferred client can't be found (or used), your editor will be used.
5168
To use a specific mail program, set the mail_client configuration option.
5169
(For Thunderbird 1.5, this works around some bugs.) Supported values for
5170
specific clients are "claws", "evolution", "kmail", "mail.app" (MacOS X's
5171
Mail.app), "mutt", and "thunderbird"; generic options are "default",
5172
"editor", "emacsclient", "mapi", and "xdg-email". Plugins may also add
5175
If mail is being sent, a to address is required. This can be supplied
5176
either on the commandline, by setting the submit_to configuration
5177
option in the branch itself or the child_submit_to configuration option
5178
in the submit branch.
5180
Two formats are currently supported: "4" uses revision bundle format 4 and
5181
merge directive format 2. It is significantly faster and smaller than
5182
older formats. It is compatible with Bazaar 0.19 and later. It is the
5183
default. "0.9" uses revision bundle format 0.9 and merge directive
5184
format 1. It is compatible with Bazaar 0.12 - 0.18.
5186
The merge directives created by bzr send may be applied using bzr merge or
5187
bzr pull by specifying a file containing a merge directive as the location.
5189
bzr send makes extensive use of public locations to map local locations into
5190
URLs that can be used by other people. See `bzr help configuration` to
5191
set them, and use `bzr info` to display them.
