"""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
"bzr log -r 3647..3649" shows the messages of revisions 3647, 3648 and 3649,
177
while "bzr diff -r 3647..3649" includes the changes done in revisions 3648 and
180

out.append("Revision Identifiers\n")
156
out.append("A revision, or a range bound, can be one of the following.\n")

allowing URLs such as::

with '~' as meaning that the rest of the path should be interpreted
265
relative to the remote user's home directory. For example if the user

``remote`` has a home directory of ``/home/remote`` on the server

bzr+ssh://remote@shell.example.com/~/myproject/trunk

Lightweight checkouts work best when you have fast reliable access to the

a lightweight checkout will be faster than a heavyweight one for any commands

356
Another possible use for a checkout is to use it with a treeless repository

containing your branches, where you maintain only one working tree by

358
switching the master branch that the checkout points to when you want to

359
work on a different branch.
403
361
Obviously to commit on a checkout you need to be able to write to the master
406
364
end. Checkouts also work on the local file system, so that all that matters is
407
365
file permissions.
409
You can change the master of a checkout by using the "switch" command (see
410
"help switch"). This will change the location that the commits are sent to.
411
The "bind" command can also be used to turn a normal branch into a heavy
412
checkout. If you would like to convert your heavy checkout into a normal
413
branch so that every commit is local, you can use the "unbind" command. To see
414
whether or not a branch is bound or not you can use the "info" command. If the
415
branch is bound it will tell you the location of the bound branch.
367
You can change the master of a checkout by using the "bind" command (see "help

repository (a shared repository). Branches can be copied and merged.
528
In addition, one branch may be bound to another one. Binding to another
529
branch indicates that commits which happen in this branch must also
530
happen in the other branch. Bazaar ensures consistency by not allowing
531
commits when the two branches are out of date. In order for a commit

to succeed, it may be necessary to update the current branch using

A criss-cross in the branch history can cause the default merge technique
643
576
to emit more conflicts than would normally be expected.
645
In complex merge cases, ``bzr merge --lca`` or ``bzr merge --weave`` may give
646
better results. You may wish to ``bzr revert`` the working tree and merge
647
again. Alternatively, use ``bzr remerge`` on particular conflicted files.
578
If you encounter criss-crosses, you can use merge --weave instead, which
579
should provide a much better result.
649
581
Criss-crosses occur in a branch's history if two branches merge the same thing
650
582
and then merge one another, or if two branches merge one another at the same
665
597
The ``weave`` merge type is not affected by this problem because it uses
666
598
line-origin detection instead of a basis revision to determine the cause of
670
_branches_out_of_sync = """Branches Out of Sync
672
When reconfiguring a checkout, tree or branch into a lightweight checkout,
673
a local branch must be destroyed. (For checkouts, this is the local branch
674
that serves primarily as a cache.) If the branch-to-be-destroyed does not
675
have the same last revision as the new reference branch for the lightweight
676
checkout, data could be lost, so Bazaar refuses.
678
How you deal with this depends on *why* the branches are out of sync.
680
If you have a checkout and have done local commits, you can get back in sync
681
by running "bzr update" (and possibly "bzr commit").
683
If you have a branch and the remote branch is out-of-date, you can push
684
the local changes using "bzr push". If the local branch is out of date, you
685
can do "bzr pull". If both branches have had changes, you can merge, commit
686
and then push your changes. If you decide that some of the changes aren't
687
useful, you can "push --overwrite" or "pull --overwrite" instead.
694
To ensure that older clients do not access data incorrectly,
695
Bazaar's policy is to introduce a new storage format whenever
696
new features requiring new metadata are added. New storage
697
formats may also be introduced to improve performance and
700
The newest format, 2a, is highly recommended. If your
701
project is not using 2a, then you should suggest to the
702
project owner to upgrade.
707
Some of the older formats have two variants:
708
a plain one and a rich-root one. The latter include an additional
709
field about the root of the tree. There is no performance cost
710
for using a rich-root format but you cannot easily merge changes
711
from a rich-root format into a plain format. As a consequence,
712
moving a project to a rich-root format takes some co-ordination
713
in that all contributors need to upgrade their repositories
714
around the same time. 2a and all future formats will be
715
implicitly rich-root.
717
See :doc:`current-formats-help` for the complete list of
718
currently supported formats. See :doc:`other-formats-help` for
719
descriptions of any available experimental and deprecated formats.
