"""Revision Identifiers
155
A revision identifier refers to a specific state of a branch's history. It
156
can be expressed in several ways. It can begin with a keyword to
157
unambiguously specify a given lookup type; some examples are 'last:1',
158
'before:yesterday' and 'submit:'.
160
Alternately, it can be given without a keyword, in which case it will be
161
checked as a revision number, a tag, a revision id, a date specification, or a
162
branch specification, in that order. For example, 'date:today' could be
163
written as simply 'today', though if you have a tag called 'today' that will
166
If 'REV1' and 'REV2' are revision identifiers, then 'REV1..REV2' denotes a
167
revision range. Examples: '3647..3649', 'date:yesterday..-1' and
168
'branch:/path/to/branch1/..branch:/branch2' (note that there are no quotes or
169
spaces around the '..').
171
Ranges are interpreted differently by different commands. To the "log" command,
172
a range is a sequence of log messages, but to the "diff" command, the range
173
denotes a change between revisions (and not a sequence of changes). In
174
addition, "log" considers a closed range whereas "diff" and "merge" consider it
175
to be open-ended, that is, they include one end but not the other. For example:
176
"brz log -r 3647..3649" shows the messages of revisions 3647, 3648 and 3649,
177
while "brz diff -r 3647..3649" includes the changes done in revisions 3648 and
180

Checkouts are source trees that are connected to a branch, so that when
353
158
you commit in the source tree, the commit goes into that branch. They
354
159
allow you to use a simpler, more centralized workflow, ignoring some of
355
Breezy's decentralized features until you want them. Using checkouts
160
Bazaar's decentralized features until you want them. Using checkouts
356
161
with shared repositories is very similar to working with SVN or CVS, but
357
162
doesn't have the same restrictions. And using checkouts still allows
358
163
others working on the project to use whatever workflow they like.
360
A checkout is created with the brz checkout command (see "help checkout").
165
A checkout is created with the bzr checkout command (see "help checkout").
361
166
You pass it a reference to another branch, and it will create a local copy
362
167
for you that still contains a reference to the branch you created the
363
168
checkout from (the master branch). Then if you make any commits they will be
404
209
end. Checkouts also work on the local file system, so that all that matters is
405
210
file permissions.
407
You can change the master of a checkout by using the "switch" command (see
408
"help switch"). This will change the location that the commits are sent to.
409
The "bind" command can also be used to turn a normal branch into a heavy
410
checkout. If you would like to convert your heavy checkout into a normal
411
branch so that every commit is local, you can use the "unbind" command. To see
412
whether or not a branch is bound or not you can use the "info" command. If the
413
branch is bound it will tell you the location of the bound branch.
212
You can change the master of a checkout by using the "bind" command (see "help
213
bind"). This will change the location that the commits are sent to. The bind
214
command can also be used to turn a branch into a heavy checkout. If you

436
Repositories in Breezy are where committed information is stored. There is
437
a repository associated with every branch.
439
Repositories are a form of database. Breezy will usually maintain this for
440
good performance automatically, but in some situations (e.g. when doing
441
very many commits in a short time period) you may want to ask brz to
442
optimise the database indices. This can be done by the 'brz pack' command.
444
By default just running 'brz init' will create a repository within the new
445
branch but it is possible to create a shared repository which allows multiple
446
branches to share their information in the same location. When a new branch is
447
created it will first look to see if there is a containing shared repository it
450
When two branches of the same project share a repository, there is
451
generally a large space saving. For some operations (e.g. branching
452
within the repository) this translates in to a large time saving.
454
To create a shared repository use the init-shared-repository command (or the
455
alias init-shared-repo). This command takes the location of the repository to
456
create. This means that 'brz init-shared-repository repo' will create a
457
directory named 'repo', which contains a shared repository. Any new branches
458
that are created in this directory will then use it for storage.
460
It is a good idea to create a repository whenever you might create more
461
than one branch of a project. This is true for both working areas where you
462
are doing the development, and any server areas that you use for hosting
463
projects. In the latter case, it is common to want branches without working
464
trees. Since the files in the branch will not be edited directly there is no
465
need to use up disk space for a working tree. To create a repository in which
466
the branches will not have working trees pass the '--no-trees' option to
467
'init-shared-repository'.
471
init-shared-repository Create a shared repository. Use --no-trees to create
472
one in which new branches won't get a working tree.
479
A working tree is the contents of a branch placed on disk so that you can
480
see the files and edit them. The working tree is where you make changes to a
481
branch, and when you commit the current state of the working tree is the
482
snapshot that is recorded in the commit.
484
When you push a branch to a remote system, a working tree will not be
485
created. If one is already present the files will not be updated. The
486
branch information will be updated and the working tree will be marked
487
as out-of-date. Updating a working tree remotely is difficult, as there
488
may be uncommitted changes or the update may cause content conflicts that are
489
difficult to deal with remotely.
491
If you have a branch with no working tree you can use the 'checkout' command
492
to create a working tree. If you run 'brz checkout .' from the branch it will
493
create the working tree. If the branch is updated remotely, you can update the
494
working tree by running 'brz update' in that directory.
496
If you have a branch with a working tree that you do not want the 'remove-tree'
497
command will remove the tree if it is safe. This can be done to avoid the
498
warning about the remote working tree not being updated when pushing to the
499
branch. It can also be useful when working with a '--no-trees' repository
500
(see 'brz help repositories').
502
If you want to have a working tree on a remote machine that you push to you
503
can either run 'brz update' in the remote branch after each push, or use some
504
other method to update the tree during the push. There is an 'rspush' plugin
505
that will update the working tree using rsync as well as doing a push. There
506
is also a 'push-and-update' plugin that automates running 'brz update' via SSH
511
checkout Create a working tree when a branch does not have one.
512
remove-tree Removes the working tree from a branch when it is safe to do so.
513
update When a working tree is out of sync with its associated branch
514
this will update the tree to match the branch.
521
A branch consists of the state of a project, including all of its
522
history. All branches have a repository associated (which is where the
523
branch history is stored), but multiple branches may share the same
524
repository (a shared repository). Branches can be copied and merged.
526
In addition, one branch may be bound to another one. Binding to another
527
branch indicates that commits which happen in this branch must also
528
happen in the other branch. Breezy ensures consistency by not allowing
529
commits when the two branches are out of date. In order for a commit
530
to succeed, it may be necessary to update the current branch using

655
A criss-cross in the branch history can cause the default merge technique
656
to emit more conflicts than would normally be expected.
658
In complex merge cases, ``brz merge --lca`` or ``brz merge --weave`` may give
659
better results. You may wish to ``brz revert`` the working tree and merge
660
again. Alternatively, use ``brz remerge`` on particular conflicted files.
662
Criss-crosses occur in a branch's history if two branches merge the same thing
663
and then merge one another, or if two branches merge one another at the same
664
time. They can be avoided by having each branch only merge from or into a
665
designated central branch (a "star topology").
667
Criss-crosses cause problems because of the way merge works. Breezy's default
668
merge is a three-way merger; in order to merge OTHER into THIS, it must
669
find a basis for comparison, BASE. Using BASE, it can determine whether
670
differences between THIS and OTHER are due to one side adding lines, or
671
from another side removing lines.
673
Criss-crosses mean there is no good choice for a base. Selecting the recent
674
merge points could cause one side's changes to be silently discarded.
675
Selecting older merge points (which Breezy does) mean that extra conflicts
678
The ``weave`` merge type is not affected by this problem because it uses
679
line-origin detection instead of a basis revision to determine the cause of
683
_branches_out_of_sync = """Branches Out of Sync
685
When reconfiguring a checkout, tree or branch into a lightweight checkout,
686
a local branch must be destroyed. (For checkouts, this is the local branch
687
that serves primarily as a cache.) If the branch-to-be-destroyed does not
688
have the same last revision as the new reference branch for the lightweight
689
checkout, data could be lost, so Breezy refuses.
691
How you deal with this depends on *why* the branches are out of sync.
693
If you have a checkout and have done local commits, you can get back in sync
694
by running "brz update" (and possibly "brz commit").
696
If you have a branch and the remote branch is out-of-date, you can push
697
the local changes using "brz push". If the local branch is out of date, you
698
can do "brz pull". If both branches have had changes, you can merge, commit
699
and then push your changes. If you decide that some of the changes aren't
700
useful, you can "push --overwrite" or "pull --overwrite" instead.
707
To ensure that older clients do not access data incorrectly,
708
Breezy's policy is to introduce a new storage format whenever
709
new features requiring new metadata are added. New storage
710
formats may also be introduced to improve performance and
713
The newest format, 2a, is highly recommended. If your
714
project is not using 2a, then you should suggest to the
715
project owner to upgrade.
720
Some of the older formats have two variants:
721
a plain one and a rich-root one. The latter include an additional
722
field about the root of the tree. There is no performance cost
723
for using a rich-root format but you cannot easily merge changes
724
from a rich-root format into a plain format. As a consequence,
725
moving a project to a rich-root format takes some co-ordination
726
in that all contributors need to upgrade their repositories
727
around the same time. 2a and all future formats will be
728
implicitly rich-root.
730
See :doc:`current-formats-help` for the complete list of
731
currently supported formats. See :doc:`other-formats-help` for
732
descriptions of any available experimental and deprecated formats.
