bzrlib.tests.test_hashcache.FakeHashCache : API documentation

Hashcache that consults a fake clock rather than the real one.

This lets us examine how old or new files would be handled, without actually having to wait for time to pass.

Method	__init__	Create a hash cache in base dir, and set the file mode to mode.
Method	put_file	Undocumented
Method	pretend_to_sleep	Undocumented
Method	_fingerprint	Undocumented
Method	_really_sha1_file	Calculate the SHA1 of a file by reading the full text
Method	_cutoff_time	Return cutoff time.

Inherited from HashCache:

Method	cache_file_name	Undocumented
Method	clear	Discard all cached information.
Method	scan	Scan all files and remove entries where the cache entry is obsolete.
Method	get_sha1	Return the sha1 of a file.
Method	write	Write contents of cache to file.
Method	read	Reinstate cache from file.

def __init__(self):

overrides bzrlib.hashcache.HashCache.__init__

Create a hash cache in base dir, and set the file mode to mode.

Parameters content_filter_stack_provider a function that takes a path (relative to the top of the tree) and a file-id as parameters and returns a stack of ContentFilters. If None, no content filtering is performed.

def _really_sha1_file(self, abspath, filters):

overrides bzrlib.hashcache.HashCache._really_sha1_file

Calculate the SHA1 of a file by reading the full text

def _cutoff_time(self):

overrides bzrlib.hashcache.HashCache._cutoff_time

Return cutoff time.

Files modified more recently than this time are at risk of being undetectably modified and so can't be cached.
