def rebase(ui, repo, **opts):
"""move changeset (and descendants) to a different branch
Rebase uses repeated merging to graft changesets from one part of
history (the source) onto another (the destination). This can be
useful for linearizing *local* changes relative to a master
development tree.
You should not rebase changesets that have already been shared
with others. Doing so will force everybody else to perform the
same rebase or they will end up with duplicated changesets after
pulling in your rebased changesets.
In its default configuration, Mercurial will prevent you from
rebasing published changes. See :hg:`help phases` for details.
If you don't specify a destination changeset (``-d/--dest``),
rebase uses the current branch tip as the destination. (The
destination changeset is not modified by rebasing, but new
changesets are added as its descendants.)
You can specify which changesets to rebase in two ways: as a
"source" changeset or as a "base" changeset. Both are shorthand
for a topologically related set of changesets (the "source
branch"). If you specify source (``-s/--source``), rebase will
rebase that changeset and all of its descendants onto dest. If you
specify base (``-b/--base``), rebase will select ancestors of base
back to but not including the common ancestor with dest. Thus,
``-b`` is less precise but more convenient than ``-s``: you can
specify any changeset in the source branch, and rebase will select
the whole branch. If you specify neither ``-s`` nor ``-b``, rebase
uses the parent of the working directory as the base.
For advanced usage, a third way is available through the ``--rev``
option. It allows you to specify an arbitrary set of changesets to
rebase. Descendants of revs you specify with this option are not
automatically included in the rebase.
By default, rebase recreates the changesets in the source branch
as descendants of dest and then destroys the originals. Use
``--keep`` to preserve the original source changesets. Some
changesets in the source branch (e.g. merges from the destination
branch) may be dropped if they no longer contribute any change.
One result of the rules for selecting the destination changeset
and source branch is that, unlike ``merge``, rebase will do
nothing if you are at the branch tip of a named branch
with two heads. You need to explicitly specify source and/or
destination (or ``update`` to the other head, if it's the head of
the intended source branch).
If a rebase is interrupted to manually resolve a merge, it can be
continued with --continue/-c or aborted with --abort/-a.
.. container:: verbose
Examples:
- move "local changes" (current commit back to branching point)
to the current branch tip after a pull::
hg rebase
- move a single changeset to the stable branch::
hg rebase -r 5f493448 -d stable
- splice a commit and all its descendants onto another part of history::
hg rebase --source c0c3 --dest 4cf9
- rebase everything on a branch marked by a bookmark onto the
default branch::
hg rebase --base myfeature --dest default
- collapse a sequence of changes into a single commit::
hg rebase --collapse -r 1520:1525 -d .
- move a named branch while preserving its name::
hg rebase -r "branch(featureX)" -d 1.3 --keepbranches
Returns 0 on success, 1 if nothing to rebase or there are
unresolved conflicts.

def rebase(ui, repo, **opts):
"""move changeset (and descendants) to a different branch
Rebase uses repeated merging to graft changesets from one part of
history (the source) onto another (the destination). This can be
useful for linearizing *local* changes relative to a master
development tree.
You should not rebase changesets that have already been shared
with others. Doing so will force everybody else to perform the
same rebase or they will end up with duplicated changesets after
pulling in your rebased changesets.
In its default configuration, Mercurial will prevent you from
rebasing published changes. See :hg:`help phases` for details.
If you don't specify a destination changeset (``-d/--dest``),
rebase uses the tipmost head of the current named branch as the
destination. (The destination changeset is not modified by
rebasing, but new changesets are added as its descendants.)
You can specify which changesets to rebase in two ways: as a
"source" changeset or as a "base" changeset. Both are shorthand
for a topologically related set of changesets (the "source
branch"). If you specify source (``-s/--source``), rebase will
rebase that changeset and all of its descendants onto dest. If you
specify base (``-b/--base``), rebase will select ancestors of base
back to but not including the common ancestor with dest. Thus,
``-b`` is less precise but more convenient than ``-s``: you can
specify any changeset in the source branch, and rebase will select
the whole branch. If you specify neither ``-s`` nor ``-b``, rebase
uses the parent of the working directory as the base.
For advanced usage, a third way is available through the ``--rev``
option. It allows you to specify an arbitrary set of changesets to
rebase. Descendants of revs you specify with this option are not
automatically included in the rebase.
By default, rebase recreates the changesets in the source branch
as descendants of dest and then destroys the originals. Use
``--keep`` to preserve the original source changesets. Some
changesets in the source branch (e.g. merges from the destination
branch) may be dropped if they no longer contribute any change.
One result of the rules for selecting the destination changeset
and source branch is that, unlike ``merge``, rebase will do
nothing if you are at the latest (tipmost) head of a named branch
with two heads. You need to explicitly specify source and/or
destination (or ``update`` to the other head, if it's the head of
the intended source branch).
If a rebase is interrupted to manually resolve a merge, it can be
continued with --continue/-c or aborted with --abort/-a.
Returns 0 on success, 1 if nothing to rebase.

This command accepts an optional name of a shelved change to
restore. If none is given, the most recent shelved change is used.
If a shelved change is applied successfully, the bundle that
contains the shelved changes is moved to a backup location
(.hg/shelve-backup).
Since you can restore a shelved change on top of an arbitrary
commit, it is possible that unshelving will result in a conflict
between your changes and the commits you are unshelving onto. If
this occurs, you must resolve the conflict, then use
``--continue`` to complete the unshelve operation. (The bundle
will not be moved until you successfully complete the unshelve.)
(Alternatively, you can use ``--abort`` to abandon an unshelve
that causes a conflict. This reverts the unshelved changes, and
leaves the bundle in place.)
After a successful unshelve, the shelved changes are stored in a
backup directory. Only the N most recent backups are kept. N
defaults to 10 but can be overridden using the ``shelve.maxbackups``
configuration option.
.. container:: verbose
Timestamp in seconds is used to decide order of backups. More
than ``maxbackups`` backups are kept, if same timestamp
prevents from deciding exact order of them, for safety.
