discovery: add extinct changesets to outgoing.excluded...
discovery: add extinct changesets to outgoing.excluded Before this change, push would incorrectly fast-path the bundle generation when extinct changesets are involved, because they are not added to outgoing.excluded. The reason to do so are related to outgoing.excluded being assumed to contain only secret changesets by scmutil.nochangesfound(), when displaying warnings like: changes found (ignored 9 secret changesets) Still, outgoing.excluded seems like a good API to report the extinct changesets instead of dedicated code and nothing in the docstring indicates it to be bound to secret changesets. This patch adds extinct changesets to outgoing.excluded and fixes scmutil.nochangesfound() to filter the excluded node list. Original version and test by Pierre-Yves.David@ens-lyon.org

Rebasing
D onto H - simple rebase:
$ hg clone -q -u . a a1
$ cd a1
$ hg tglog

$ hg rebase -s 3 -d 7

D onto F - intermediate point:
$ hg clone -q -u . a a2
$ cd a2
$ hg rebase -s 3 -d 5
saved backup bundle to $TESTTMP/a2/.hg/strip-backup/*-backup.hg (glob)
$ hg tglog

$ cd a4
$ hg rebase -s 5 -d 4
saved backup bundle to $TESTTMP/a4/.hg/strip-backup/*-backup.hg (glob)

G onto H - merged revision having a parent in ancestors of target:
$ hg clone -q -u . a a5
$ cd a5
$ hg rebase -s 6 -d 7
saved backup bundle to $TESTTMP/a5/.hg/strip-backup/*-backup.hg (glob)

F onto B - G maintains E as parent:
$ hg clone -q -u . a a6
$ cd a6
$ hg rebase -s 5 -d 1
saved backup bundle to $TESTTMP/a6/.hg/strip-backup/*-backup.hg (glob)

These will fail (using --source):
G onto F - rebase onto an ancestor:
$ hg clone -q -u . a a7
$ cd a7
$ hg rebase -s 6 -d 5
nothing to rebase
[1]
F onto G - rebase onto a descendant:
$ hg rebase -s 5 -d 6
abort: source is ancestor of destination
[255]
G onto B - merge revision with both parents not in ancestors of target:
$ hg rebase -s 6 -d 1
abort: cannot use revision 6 as base, result would have 3 parents
[255]
These will abort gracefully (using --base):
G onto G - rebase onto same changeset:
$ hg rebase -b 6 -d 6
nothing to rebase
[1]
G onto F - rebase onto an ancestor:
$ hg rebase -b 6 -d 5
nothing to rebase
[1]
F onto G - rebase onto a descendant:
$ hg rebase -b 5 -d 6
nothing to rebase
[1]
C onto A - rebase onto an ancestor:
$ hg rebase -d 0 -s 2
saved backup bundle to $TESTTMP/a7/.hg/strip-backup/5fddd98957c8-backup.hg (glob)

Check rebasing public changeset
$ hg pull --config phases.publish=True -q -r 6 . # update phase of 6

$ hg rebase -d 5 -b 6 --keep
Check rebasing mutable changeset
Source phase greater or equal to destination phase: new changeset get the phase of source:
$ hg rebase -s9 -d0

Simple case with keep:
Source on have two descendant heads but ask for one
$ hg clone -q -u . ah ah1

rebase with multiple root.
We rebase E and G on B
We would expect heads are I, F if it was supported
$ hg clone -q -u . ah ah6
$ cd ah6
$ hg rebase -r '(4+6)::' -d 1
abort: can't rebase multiple roots
