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

Some implementations of cp can't create hardlinks (replaces 'cp -al' on Linux):
$ cat > linkcp.py <<EOF
> from mercurial import util
> import sys
> util.copyfiles(sys.argv[1], sys.argv[2], hardlink=True)
> EOF
$ linkcp()
> {

Prepare repo r1:
$ hg init r1
$ cd r1
$ echo c1 > f1
$ hg add f1
$ hg ci -m0
$ mkdir d1
$ cd d1
$ echo c2 > f2
$ hg add f2
$ hg ci -m1
$ cd ../..
$ nlinksdir r1/.hg/store

Repos r1 and r2 should now contain hardlinked files:
$ nlinksdir r1/.hg/store
2 r1/.hg/store/00changelog.i
2 r1/.hg/store/00manifest.i
2 r1/.hg/store/data/d1/f2.i

2 r2/.hg/store/data/d1/f2.i
2 r2/.hg/store/data/f1.i
2 r2/.hg/store/fncache
Repo r3 should not be hardlinked:
$ nlinksdir r3/.hg/store
1 r3/.hg/store/00changelog.i
1 r3/.hg/store/00manifest.i
1 r3/.hg/store/data/d1/f2.i
1 r3/.hg/store/data/f1.i
1 r3/.hg/store/fncache
1 r3/.hg/store/phaseroots
1 r3/.hg/store/undo
1 r3/.hg/store/undo.phaseroots
Create a non-inlined filelog in r3:
$ cd r3/d1
>>> f = open('data1', 'wb')
>>> for x in range(10000):
... f.write("%s\n" % str(x))
>>> f.close()
$ for j in 0 1 2 3 4 5 6 7 8 9; do
> cat data1 >> f2
> hg commit -m$j
> done
$ cd ../..
$ nlinksdir r3/.hg/store
1 r3/.hg/store/00changelog.i
1 r3/.hg/store/00manifest.i
1 r3/.hg/store/data/d1/f2.d
1 r3/.hg/store/data/d1/f2.i

1 r3/.hg/store/fncache
1 r3/.hg/store/phaseroots
1 r3/.hg/store/undo
1 r3/.hg/store/undo.phaseroots
Push to repo r1 should break up most hardlinks in r2:
$ hg -R r2 verify

2 files, 2 changesets, 2 total revisions
$ cd r3
$ hg push

$ hg up

Committing a change to f1 in r1 must break up hardlink f1.i in r2:
$ echo c1c1 >> f1
$ hg ci -m00
$ cd ..
$ nlinksdir r2/.hg/store
1 r2/.hg/store/00changelog.i
1 r2/.hg/store/00manifest.i
1 r2/.hg/store/data/d1/f2.i
1 r2/.hg/store/data/f1.i
1 r2/.hg/store/fncache
$ cd r3
$ hg tip --template '{rev}:{node|short}\n'
11:a6451b6bc41f
$ echo bla > f1
$ hg ci -m1
$ cd ..
Create hardlinked copy r4 of r3 (on Linux, we would call 'cp -al'):
$ linkcp r3 r4
r4 has hardlinks in the working dir (not just inside .hg):
$ nlinksdir r4
2 r4/.hg/00changelog.i
2 r4/.hg/branch
2 r4/.hg/cache/branchheads
2 r4/.hg/cache/tags

Update back to revision 11 in r4 should break hardlink of file f1:
$ hg -R r4 up 11
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ nlinksdir r4
