bzrlib.tests.per_branch.test_get_revision_id_to_revno_map.TestCaching : API documentation

Tests for the caching of branches' dotted revno generation.

When locked, branches should avoid regenerating revision_id=>dotted revno mapping.

When not locked, obviously the revision_id => dotted revno will need to be regenerated or reread each time.

We test if revision_history is using the cache by instrumenting the branch's _gen_revno_map method, which is called by get_revision_id_to_revno_map.

Method	get_instrumented_branch	Get a branch and monkey patch it to log calls to _gen_revno_map.
Method	test_unlocked	Repeated calls will call _gen_revno_map each time.
Method	test_locked	Repeated calls will only call _gen_revno_map once.
Method	test_set_revision_history_when_locked	Calling set_revision_history should reset the cache.
Method	test_set_last_revision_info_when_locked	Calling set_last_revision_info should reset the cache.

Method	setUp	Undocumented
Method	get_branch	Undocumented
Method	get_default_format	Undocumented
Method	make_branch	Undocumented
Method	create_tree_with_merge	Create a branch with a simple ancestry.

def get_instrumented_branch(self):

Get a branch and monkey patch it to log calls to _gen_revno_map.

Returns a tuple of (the branch, list that calls will be logged to)
