strip: add a delayedstrip method that works in a transaction
For long, the fact that strip does not work inside a transaction and some
code has to work with both obsstore and fallback to strip lead to duplicated
code like:
with repo.transaction():
....
if obsstore:
obsstore.createmarkers(...)
if not obsstore:
repair.strip(...)
Things get more complex when you want to call something which may call strip
under the hood. Like you cannot simply write:
with repo.transaction():
....
rebasemod.rebase(...) # may call "strip", so this doesn't work
But you do want rebase to run inside a same transaction if possible, so the
code may look like:
with repo.transaction():
....
if obsstore:
rebasemod.rebase(...)
obsstore.createmarkers(...)
if not obsstore:
rebasemod.rebase(...)
repair.strip(...)
That's ugly and error-prone. Ideally it's possible to just write:
with repo.transaction():
rebasemod.rebase(...)
saferemovenodes(...)
This patch is the first step towards that. It adds a "delayedstrip" method
to repair.py which maintains a postclose callback in the transaction object.

==================================== Testing head checking code: Case A-7 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category A: simple case involving a branch being superceeded by another. TestCase 7: multi-changeset branch, split on multiple other, (head on its own branch), same number of head .. old-state: .. .. * 2 branch (1-changeset, and 2-changesets) .. .. new-state: .. .. * 1 new branch superceeding the head of the old-2-changesets-branch, .. * 1 new changesets on the old-1-changeset-branch superceeding the base of the other .. .. expected-result: .. .. * push allowed .. .. graph-summary: .. ..
