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.
Returns 0 on success, 1 if nothing to rebase or there are
unresolved conflicts.

This is a generic function used to perform history rewriting.
Given an iterable of input nodes, a function will be called which is
expected to produce a new changeset to replace the input node. The
function signature should be:
def createfn(repo, ctx, revmap, copyfilectxfn):
It is passed a repo, the changectx being rewritten, a map of old to new
revisions that have been changed so far, and a function that can be used
as the memctx callback for obtaining memfilectx when no file modifications
are to be performed (a common pattern). The function should return an
*uncommitted* memctx holding the new changeset info.
We currently restrict that the createfn callback must return a new
changeset and that no file changes may occur. Restricting file changes
satisfies the requirements this function was invented for and keeps the
implementation simple.
After the memctx is obtained, it is committed. Children changesets are
rebased automatically after all changesets have been rewritten.
After the old to new mapping is obtained, bookmarks are moved and old
changesets are made obsolete or stripped, depending on what is appropriate
for the repo configuration.

"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.
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.

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.

be one backout changeset queued up for each backed-out changeset.
The --apply option will reapply a patch instead of backing it out, which

you want to try again.
Normally, qbackout will error out if the patch (backout or application)

queue without pushing it so you can fix the conflicts manually.
Examples:
hg qbackout -r 20 -r 30 # backout revisions 20 and 30
hg qbackout -r 20+30 # backout revisions 20 and 30
hg qbackout -r 20+30:32 # backout revisions 20, 30, 31, and 32

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.
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.
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.

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.

This is a generic function used to perform history rewriting.
Given an iterable of input nodes, a function will be called which is
expected to produce a new changeset to replace the input node. The
function signature should be:
def createfn(repo, ctx, revmap, copyfilectxfn):
It is passed a repo, the changectx being rewritten, a map of old to new
revisions that have been changed so far, and a function that can be used
as the memctx callback for obtaining memfilectx when no file modifications
are to be performed (a common pattern). The function should return an
*uncommitted* memctx holding the new changeset info.
We currently restrict that the createfn callback must return a new
changeset and that no file changes may occur. Restricting file changes
satisfies the requirements this function was invented for and keeps the
implementation simple.
After the memctx is obtained, it is committed. Children changesets are
rebased automatically after all changesets have been rewritten.
After the old to new mapping is obtained, bookmarks are moved and old
changesets are made obsolete or stripped, depending on what is appropriate
for the repo configuration.
This function handles locking the repository and performing as many actions
in a transaction as possible.
Before any changes are made, we verify the state of the repo is sufficient
for transformation to occur and abort otherwise.
