Martin Geisler
|
r7999 | Rebase uses repeated merging to graft changesets from one part of | ||
Greg Ward
|
r10646 | history (the source) onto another (the destination). This can be | ||
Martin Geisler
|
r11188 | useful for linearizing *local* changes relative to a master | ||
Greg Ward
|
r10646 | development tree. | ||
Martin Geisler
|
r11188 | 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. | ||||
Greg Ward
|
r10646 | 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 | ||||
Martin Geisler
|
r10659 | "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. | ||||
Greg Ward
|
r10646 | |||
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). | ||||
