any of the named files are already versioned.
694
In recursive mode (the default), files are treated the same way
695
but the behaviour for directories is different. Directories that
696
are already versioned do not give a warning. All directories,
697
whether already versioned or not, are searched for files or
698
subdirectories that are neither versioned or ignored, and these
699
are added. This search proceeds recursively into versioned
700
directories. If no names are given '.' is assumed.
702
A warning will be printed when nested trees are encountered,
703
unless they are explicitly ignored.
705
Therefore simply saying 'brz add' will version all files that
706
are currently unknown.
708
Adding a file whose parent directory is not versioned will
709
implicitly add the parent, and so on up to the root. This means

you should never need to explicitly add a directory, they'll just
711
get added when you add a file in the directory.
713
--dry-run will show which files would be added, but not actually

--file-ids-from will try to use the file ids from the supplied path.
717
It looks up ids trying to find a matching parent directory with the
718
same filename, and then by pure path. This option is rarely needed

log is brz's default tool for exploring the history of a branch.
2479
The branch to use is taken from the first parameter. If no parameters
2480
are given, the branch containing the working directory is logged.
2481
Here are some simple examples::
2483
brz log log the current branch
2484
brz log foo.py log a file in its branch
2485
brz log http://server/branch log a branch on a server
2487
The filtering, ordering and information shown for each revision can
2488
be controlled as explained below. By default, all revisions are
2489
shown sorted (topologically) so that newer revisions appear before
2490
older ones and descendants always appear before ancestors. If displayed,
2491
merged revisions are shown indented under the revision in which they
2496
The log format controls how information about each revision is
2497
displayed. The standard log formats are called ``long``, ``short``
2498
and ``line``. The default is long. See ``brz help log-formats``
2499
for more details on log formats.
2501
The following options can be used to control what information is
2504
-l N display a maximum of N revisions
2505
-n N display N levels of revisions (0 for all, 1 for collapsed)
2506
-v display a status summary (delta) for each revision
2507
-p display a diff (patch) for each revision
2508
--show-ids display revision-ids (and file-ids), not just revnos
2510
Note that the default number of levels to display is a function of the
2511
log format. If the -n option is not used, the standard log formats show
2512
just the top level (mainline).
2514
Status summaries are shown using status flags like A, M, etc. To see
2515
the changes explained using words like ``added`` and ``modified``
2516
instead, use the -vv option.
2520
To display revisions from oldest to newest, use the --forward option.
2521
In most cases, using this option will have little impact on the total
2522
time taken to produce a log, though --forward does not incrementally
2523
display revisions like --reverse does when it can.
2525
:Revision filtering:
2527
The -r option can be used to specify what revision or range of revisions
2528
to filter against. The various forms are shown below::
2530
-rX display revision X
2531
-rX.. display revision X and later
2532
-r..Y display up to and including revision Y
2533
-rX..Y display from X to Y inclusive
2535
See ``brz help revisionspec`` for details on how to specify X and Y.
2536
Some common examples are given below::
2538
-r-1 show just the tip
2539
-r-10.. show the last 10 mainline revisions
2540
-rsubmit:.. show what's new on this branch
2541
-rancestor:path.. show changes since the common ancestor of this
2542
branch and the one at location path
2543
-rdate:yesterday.. show changes since yesterday
2545
When logging a range of revisions using -rX..Y, log starts at
2546
revision Y and searches back in history through the primary
2547
("left-hand") parents until it finds X. When logging just the
2548
top level (using -n1), an error is reported if X is not found
2549
along the way. If multi-level logging is used (-n0), X may be
2550
a nested merge revision and the log will be truncated accordingly.
2554
If parameters are given and the first one is not a branch, the log
2555
will be filtered to show only those revisions that changed the
2556
nominated files or directories.
2558
Filenames are interpreted within their historical context. To log a
2559
deleted file, specify a revision range so that the file existed at
2560
the end or start of the range.
2562
Historical context is also important when interpreting pathnames of
2563
renamed files/directories. Consider the following example:
2565
* revision 1: add tutorial.txt

* revision 2: modify tutorial.txt
2567
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2571
* ``brz log guide.txt`` will log the file added in revision 1
2573
* ``brz log tutorial.txt`` will log the new file added in revision 3
2575
* ``brz log -r2 -p tutorial.txt`` will show the changes made to
2576
the original file in revision 2.
2578

was no file called guide.txt in revision 2.
2581
Renames are always followed by log. By design, there is no need to
2582
explicitly ask for this (and no way to stop logging a file back
2583
until it was last renamed).
2587
The --match option can be used for finding revisions that match a
2588
regular expression in a commit message, committer, author or bug.
2589
Specifying the option several times will match any of the supplied
2590
expressions. --match-author, --match-bugs, --match-committer and
2591
--match-message can be used to only match a specific field.
2595
GUI tools and IDEs are often better at exploring history than command
2596
line tools: you may prefer qlog or viz from qbzr or bzr-gtk, the
2597
bzr-explorer shell, or the Loggerhead web interface. See the Bazaar
2598
Plugin Guide <http://doc.bazaar.canonical.com/plugins/en/> and
2599
<http://wiki.bazaar.canonical.com/IDEIntegration>.
2601
You may find it useful to add the aliases below to ``breezy.conf``::
2605
top = log -l10 --line
2608
``brz tip`` will then show the latest revision while ``brz top``
2609
will show the last 10 mainline revisions. To see the details of a
2610
particular revision X, ``brz show -rX``.
2612
If you are interested in looking deeper into a particular merge X,
2613
use ``brz log -n0 -rX``.
2615
``brz log -v`` on a branch with lots of history is currently
2616
very slow. A fix for this issue is currently under development.
2617
With or without that fix, it is recommended that a revision range
2618
be given when using the -v option.
2620
brz has a generic full-text matching plugin, brz-search, that can be
2621
used to find revisions matching user names, commit messages, etc.
2622
Among other features, this plugin can find all revisions containing
2623
a list of words but not others.
2625
When exploring non-mainline history on large projects with deep
2626
history, the performance of log can be greatly improved by installing
2627
the historycache plugin. This plugin buffers historical information
2628
trading disk space for faster speed.

3441
An explanatory message needs to be given for each commit. This is
3442
often done by using the --message option (getting the message from the
3443
command line) or by using the --file option (getting the message from
3444
a file). If neither of these options is given, an editor is opened for
3445
the user to enter the message. To see the changed files in the
3446
boilerplate text loaded into the editor, use the --show-diff option.
3448
By default, the entire tree is committed and the person doing the
3449
commit is assumed to be the author. These defaults can be overridden
3454
If selected files are specified, only changes to those files are
3455
committed. If a directory is specified then the directory and
3456
everything within it is committed.
3458
When excludes are given, they take precedence over selected files.
3459
For example, to commit only changes within foo, but not changes
3462
brz commit foo -x foo/bar
3464
A selective commit after a merge is not yet supported.
3468
If the author of the change is not the same person as the committer,
3469
you can specify the author's name using the --author option. The
3470
name should be in the same format as a committer-id, e.g.
3471
"John Doe <jdoe@example.com>". If there is more than one author of
3472
the change you can specify the option multiple times, once for each
3477
A common mistake is to forget to add a new file or directory before
3478
running the commit command. The --strict option checks for unknown
3479
files and aborts the commit if any are found. More advanced pre-commit
3480
checks can be implemented by defining hooks. See ``brz help hooks``
3485
If you accidentally commit the wrong changes or make a spelling
3486
mistake in the commit message say, you can use the uncommit command
3487
to undo it. See ``brz help uncommit`` for details.
3489
Hooks can also be configured to run after a commit. This allows you
3490
to trigger updates to external systems like bug trackers. The --fixes
3491
option can be used to record the association between a revision and
3492
one or more bugs. See ``brz help bugs`` for details.

3791
When the default format has changed after a major new release of
3792
Bazaar/Breezy, you may be informed during certain operations that you
3793
should upgrade. Upgrading to a newer format may improve performance
3794
or make new features available. It may however limit interoperability
3795
with older repositories or with older versions of Bazaar or Breezy.
3797
If you wish to upgrade to a particular format rather than the
3798
current default, that can be specified using the --format option.
3799
As a consequence, you can use the upgrade command this way to
3800
"downgrade" to an earlier format, though some conversions are
3801
a one way process (e.g. changing from the 1.x default to the
3802
2.x default) so downgrading is not always possible.
3804
A backup.bzr.~#~ directory is created at the start of the conversion
3805
process (where # is a number). By default, this is left there on
3806
completion. If the conversion fails, delete the new .bzr directory
3807
and rename this one back in its place. Use the --clean option to ask
3808
for the backup.bzr directory to be removed on successful conversion.
3809
Alternatively, you can delete it by hand if everything looks good
3812
If the location given is a shared repository, dependent branches
3813
are also converted provided the repository converts successfully.
3814
If the conversion of a branch fails, remaining branches are still

If arguments are given, they are regular expressions that say which tests
4014
should run. Tests matching any expression are run, and other tests are
4017
Alternatively if --first is given, matching tests are run first and then
4018
all other tests are run. This is useful if you have been working in a
4019
particular area, but want to make sure nothing else was broken.
4021
If --exclude is given, tests that match that regular expression are
4022
excluded, regardless of whether they match --first or not.
4024
To help catch accidential dependencies between tests, the --randomize
4025
option is useful. In most cases, the argument used is the word 'now'.
4026
Note that the seed used for the random number generator is displayed
4027
when this option is used. The seed can be explicitly passed as the
4028
argument to this option if required. This enables reproduction of the
4029
actual ordering used if and when an order sensitive problem is encountered.
4031
If --list-only is given, the tests that would be run are listed. This is
4032
useful when combined with --first, --exclude and/or --randomize to
4033
understand their impact. The test harness reports "Listed nn tests in ..."
4034
instead of "Ran nn tests in ..." when list mode is enabled.
4036
If the global option '--no-plugins' is given, plugins are not loaded
4037
before running the selftests. This has two effects: features provided or
4038
modified by plugins will not be tested, and tests provided by plugins will
4041
Tests that need working space on disk use a common temporary directory,
4042
typically inside $TMPDIR or /tmp.

If you set BRZ_TEST_PDB=1 when running selftest, failing tests will drop

4299
The source of the merge can be specified either in the form of a branch,
4300
or in the form of a path to a file containing a merge directive generated
4301
with brz send. If neither is specified, the default is the upstream branch
4302
or the branch most recently merged using --remember. The source of the
4303
merge may also be specified in the form of a path to a file in another
4304
branch: in this case, only the modifications to that file are merged into
4305
the current working tree.
4307
When merging from a branch, by default brz will try to merge in all new
4308
work from the other branch, automatically determining an appropriate base
4309
revision. If this fails, you may need to give an explicit base.
4311
To pick a different ending revision, pass "--revision OTHER". brz will
4312
try to merge in all new work up to and including revision OTHER.
4314
If you specify two values, "--revision BASE..OTHER", only revisions BASE
4315
through OTHER, excluding BASE but including OTHER, will be merged. If this
4316
causes some revisions to be skipped, i.e. if the destination branch does
4317
not already contain revision BASE, such a merge is commonly referred to as
4318
a "cherrypick". Unlike a normal merge, Breezy does not currently track
4319
cherrypicks. The changes look like a normal commit, and the history of the
4320
changes from the other branch is not stored in the commit.
4322
Revision numbers are always relative to the source branch.
4324
Merge will do its best to combine the changes in two branches, but there
4325
are some kinds of problems only a human can fix. When it encounters those,
4326
it will mark a conflict. A conflict means that you need to fix something,
4327
before you can commit.
4329
Use brz resolve when you have fixed a problem. See also brz conflicts.
4331
If there is no default branch set, the first merge will set it (use
4332
--no-remember to avoid setting it). After that, you can omit the branch
4333
to use the default. To change the default, use --remember. The value will
4334
only be saved if the remote location can be accessed.
4336
The results of the merge are placed into the destination working
4337
directory, where they can be reviewed (with brz diff), tested, and then
4338
committed to record the result of the merge.
4340
merge refuses to run if there are any uncommitted changes, unless
4341
--force is given. If --force is given, then the changes from the source
4342
will be merged with the current working tree, including any uncommitted
4343
changes in the tree. The --force option can also be used to create a
4344
merge revision which has more than two parents.
4346
If one would like to merge changes from the working tree of the other
4347
branch without merging any committed revisions, the --uncommitted option
4350
To select only some changes to merge, use "merge -i", which will prompt
4351
you to apply each diff hunk and file change, similar to "shelve".

Set files in the working tree back to the contents of a previous revision.
4788
Giving a list of files will revert only those files. Otherwise, all files
4789
will be reverted. If the revision is not specified with '--revision', the
4790
working tree basis revision is used. A revert operation affects only the
4791
working tree, not any revision history like the branch and repository or
4792
the working tree basis revision.
4794
To remove only some changes, without reverting to a prior version, use
4795
merge instead. For example, "merge . -r -2..-3" (don't forget the ".")
4796
will remove the changes introduced by the second last commit (-2), without
4797
affecting the changes introduced by the last commit (-1). To remove
4798
certain changes on a hunk-by-hunk basis, see the shelve command.
4799
To update the branch to a specific revision or the latest revision and
4800
update the working tree accordingly while preserving local changes, see the
4803
Uncommitted changes to files that are reverted will be discarded.
4804
However, by default, any files that have been manually changed will be
4805
backed up first. (Files changed only by merge are not backed up.) Backup
4806
files have '.~#~' appended to their name, where # is a number.
4808
When you provide files, you can use their current pathname or the pathname
4809
from the target revision. So you can use revert to "undelete" a file by
4810
name. If you name a directory, all the contents of that directory will be
4813
If you have newly added files since the target revision, they will be
4814
removed. If the files to be removed have been changed, backups will be
4815
created as above. Directories containing unknown files will not be
4818
The working tree contains a list of revisions that have been merged but
4819
not yet committed. These revisions will be included as additional parents
4820
of the next commit. Normally, using revert clears that list as well as
4821
reverting the files. If any files are specified, revert leaves the list
4822
of uncommitted merges alone and reverts only the files. Use ``brz revert
4823
.`` in the tree root to revert all files but keep the recorded merges,
4824
and ``brz revert --forget-merges`` to clear the pending merge list without
4825
reverting any files.
4827
Using "brz revert --forget-merges", it is possible to apply all of the
4828
changes from a branch in a single revision. To do this, perform the merge
4829
as desired. Then doing revert with the "--forget-merges" option will keep
4830
the content of the tree as it was, but it will clear the list of pending
4831
merges. The next commit will then contain all of the changes that are
4832
present in the other branch, but without any other parent revisions.
4833

5767
A merge directive provides many things needed for requesting merges:
5769
* A machine-readable description of the merge to perform
5771
* An optional patch that is a preview of the changes requested
5773
* An optional bundle of revision data, so that the changes can be applied
5774
directly from the merge directive, without retrieving data from a
5777
`brz send` creates a compact data set that, when applied using brz
5778
merge, has the same effect as merging from the source branch.
5780
By default the merge directive is self-contained and can be applied to any
5781
branch containing submit_branch in its ancestory without needing access to
5784
If --no-bundle is specified, then Breezy doesn't send the contents of the
5785
revisions, but only a structured request to merge from the
5786
public_location. In that case the public_branch is needed and it must be
5787
up-to-date and accessible to the recipient. The public_branch is always
5788
included if known, so that people can check it later.
5790
The submit branch defaults to the parent of the source branch, but can be
5791
overridden. Both submit branch and public branch will be remembered in
5792
branch.conf the first time they are used for a particular branch. The
5793
source branch defaults to that containing the working directory, but can
5794
be changed using --from.
5796
Both the submit branch and the public branch follow the usual behavior with
5797
respect to --remember: If there is no default location set, the first send
5798
will set it (use --no-remember to avoid setting it). After that, you can
5799
omit the location to use the default. To change the default, use
5800
--remember. The value will only be saved if the location can be accessed.
5802
In order to calculate those changes, brz must analyse the submit branch.
5803
Therefore it is most efficient for the submit branch to be a local mirror.
5804
If a public location is known for the submit_branch, that location is used
5805
in the merge directive.
5807
The default behaviour is to send the merge directive by mail, unless -o is
5808
given, in which case it is sent to a file.
5810
Mail is sent using your preferred mail program. This should be transparent
5811
on Windows (it uses MAPI). On Unix, it requires the xdg-email utility.
5812
If the preferred client can't be found (or used), your editor will be used.
5814
To use a specific mail program, set the mail_client configuration option.
5815
Supported values for specific clients are "claws", "evolution", "kmail",
5816
"mail.app" (MacOS X's Mail.app), "mutt", and "thunderbird"; generic options
5817
are "default", "editor", "emacsclient", "mapi", and "xdg-email". Plugins
5818
may also add supported clients.
5820
If mail is being sent, a to address is required. This can be supplied
5821
either on the commandline, by setting the submit_to configuration
5822
option in the branch itself or the child_submit_to configuration option
5823
in the submit branch.
5825
The merge directives created by brz send may be applied using brz merge or
5826
brz pull by specifying a file containing a merge directive as the location.
5828
brz send makes extensive use of public locations to map local locations into
5829
URLs that can be used by other people. See `brz help configuration` to
5830
set them, and use `brz info` to display them.

Views provide a mask over the tree so that users can focus on
6328
a subset of a tree when doing their work. After creating a view,
6329
commands that support a list of files - status, diff, commit, etc -
6330
effectively have that list of files implicitly given each time.
6331
An explicit list of files can still be given but those files
6332
must be within the current view.
6334
In most cases, a view has a short life-span: it is created to make
6335
a selected change and is deleted once that change is committed.
6336
At other times, you may wish to create one or more named views
6337
and switch between them.
6339
To disable the current view without deleting it, you can switch to
6340
the pseudo view called ``off``. This can be useful when you need
6341
to see the whole tree for an operation or two (e.g. merge) but

want to switch back to your view after that.
