"""Revision Identifiers
157
A revision identifier refers to a specific state of a branch's history. It
158
can be expressed in several ways. It can begin with a keyword to
159
unambiguously specify a given lookup type; some examples are 'last:1',
160
'before:yesterday' and 'submit:'.
162
Alternately, it can be given without a keyword, in which case it will be
163
checked as a revision number, a tag, a revision id, a date specification, or a
164
branch specification, in that order. For example, 'date:today' could be
165
written as simply 'today', though if you have a tag called 'today' that will
168
If 'REV1' and 'REV2' are revision identifiers, then 'REV1..REV2' denotes a
169
revision range. Examples: '3647..3649', 'date:yesterday..-1' and
170
'branch:/path/to/branch1/..branch:/branch2' (note that there are no quotes or
171
spaces around the '..').
173
Ranges are interpreted differently by different commands. To the "log" command,
174
a range is a sequence of log messages, but to the "diff" command, the range
175
denotes a change between revisions (and not a sequence of changes). In
176
addition, "log" considers a closed range whereas "diff" and "merge" consider it
177
to be open-ended, that is, they include one end but not the other. For example:
178
"bzr log -r 3647..3649" shows the messages of revisions 3647, 3648 and 3649,
179
while "bzr diff -r 3647..3649" includes the changes done in revisions 3648 and
182
The keywords used as revision selection methods are the following:
137
out.append("Revision Identifiers\n")
138
out.append("A revision, or a range bound, can be one of the following.\n")
185
details.append("\nIn addition, plugins can provide other keywords.")

649
A criss-cross in the branch history can cause the default merge technique
650
to emit more conflicts than would normally be expected.
652
In complex merge cases, ``bzr merge --lca`` or ``bzr merge --weave`` may give
653
better results. You may wish to ``bzr revert`` the working tree and merge
654
again. Alternatively, use ``bzr remerge`` on particular conflicted files.
656
Criss-crosses occur in a branch's history if two branches merge the same thing
657
and then merge one another, or if two branches merge one another at the same
658
time. They can be avoided by having each branch only merge from or into a
659
designated central branch (a "star topology").
661
Criss-crosses cause problems because of the way merge works. Bazaar's default
662
merge is a three-way merger; in order to merge OTHER into THIS, it must
663
find a basis for comparison, BASE. Using BASE, it can determine whether
664
differences between THIS and OTHER are due to one side adding lines, or
665
from another side removing lines.
667
Criss-crosses mean there is no good choice for a base. Selecting the recent
668
merge points could cause one side's changes to be silently discarded.
669
Selecting older merge points (which Bazaar does) mean that extra conflicts
672
The ``weave`` merge type is not affected by this problem because it uses
673
line-origin detection instead of a basis revision to determine the cause of
677
_branches_out_of_sync = """Branches Out of Sync
679
When reconfiguring a checkout, tree or branch into a lightweight checkout,
680
a local branch must be destroyed. (For checkouts, this is the local branch
681
that serves primarily as a cache.) If the branch-to-be-destroyed does not
682
have the same last revision as the new reference branch for the lightweight
683
checkout, data could be lost, so Bazaar refuses.
685
How you deal with this depends on *why* the branches are out of sync.
687
If you have a checkout and have done local commits, you can get back in sync
688
by running "bzr update" (and possibly "bzr commit").
690
If you have a branch and the remote branch is out-of-date, you can push
691
the local changes using "bzr push". If the local branch is out of date, you
692
can do "bzr pull". If both branches have had changes, you can merge, commit
693
and then push your changes. If you decide that some of the changes aren't
694
useful, you can "push --overwrite" or "pull --overwrite" instead.
701
To ensure that older clients do not access data incorrectly,
702
Bazaar's policy is to introduce a new storage format whenever
703
new features requiring new metadata are added. New storage
704
formats may also be introduced to improve performance and
707
The newest format, 2a, is highly recommended. If your
708
project is not using 2a, then you should suggest to the
709
project owner to upgrade.
714
Some of the older formats have two variants:
715
a plain one and a rich-root one. The latter include an additional
716
field about the root of the tree. There is no performance cost
717
for using a rich-root format but you cannot easily merge changes
718
from a rich-root format into a plain format. As a consequence,
719
moving a project to a rich-root format takes some co-ordination
720
in that all contributors need to upgrade their repositories
721
around the same time. 2a and all future formats will be
722
implicitly rich-root.
724
See :doc:`current-formats-help` for the complete list of
725
currently supported formats. See :doc:`other-formats-help` for
726
descriptions of any available experimental and deprecated formats.
