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.
