"""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.
|
|
|
|
|
|
Published commits cannot be rebased (see :hg:`help phases`).
|
|
|
To copy commits, see :hg:`help graft`.
|
|
|
|
|
|
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.)
|
|
|
|
|
|
Here are the ways to select changesets::
|
|
|
|
|
|
1. Explicitly select them using ``--rev``.
|
|
|
|
|
|
2. Use ``--source`` to select a root changeset and include all of its
|
|
|
descendants.
|
|
|
|
|
|
3. Use ``--base`` to select a changeset; rebase will find ancestors
|
|
|
and their descendants which are not also ancestors of the destination.
|
|
|
|
|
|
4. If you do not specify any of ``--rev``, ``source``, or ``--base``,
|
|
|
rebase will use ``--base .`` as above.
|
|
|
|
|
|
Rebase will destroy original changesets unless you use ``--keep``.
|
|
|
It will also move your bookmarks (even if you do).
|
|
|
|
|
|
Some changesets may be dropped if they do not contribute changes
|
|
|
(e.g. merges from the destination branch).
|
|
|
|
|
|
Unlike ``merge``, rebase will do nothing if you are at the branch tip of
|
|
|
a named branch with two heads. You will need to explicitly specify source
|
|
|
and/or destination.
|
|
|
|
|
|
If a rebase is interrupted to manually resolve a conflict, 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.
