fncachestore: defer updating the fncache file to a single file open
Defers updating the fncache file with newly added entries to the end of
the transaction (on e.g. pull), doing a single open call on the fncache
file, instead of opening and closing it each time a new entry is added
to the store.
Implemented by adding a new abstract write() function on store.basicstore
and registering it as a release function on the store lock in
localrepo.lock (compare with dirstate.write).
store.fncachestore overrides write() from basicstore and calls a new
write function on the fncache object, which writes all entries to the
fncache file if it's dirty.
store.fncache.add() now just marks itself as dirty if a new name is added.
localrepo: sort hg bookmark output
sort bookmarks before we write them to stdout to get a predictable output.
templater: add bookmarks to templates and default output
as bookmarks are not dispalyed as tags anymore, we add a bookmark label
to the changeset printer.
tags: do not merge bookmarks with tags
bookmarks are no tags, therefore they should not be returned as tags.
Make sure bundlerepo doesn't leak temp files (
issue2491)
Add empty repository.close() and call it in dispatch.
Remove bundlerepository.__del__(), merging it into bundlerepository.close(),
which overrides repository.close().
http://docs.python.org/reference/datamodel.html says:
"It is not guaranteed that __del__() methods are called for objects that
still exist when the interpreter exits."
