Changes between Initial Version and Version 1 of Ticket #1240, comment 22

initial	v1
1		~~After several weeks, this mystery is mostly solved~~. In an earlier commit [https://github.com/amiller/tahoe-lafs/commit/ff8a0a593c6d6b8f1607bb908884cf233b69eaf3 ff8a0a], I introduced an error that prevented the cache from being populated correctly.
	1	With some attention from D-S and Zooko during [https://tahoe-lafs.org/trac/tahoe-lafs/wiki/MeetingNotes_2012_10_23?version=7 the weekly hangout] we have solved most of the mystery. In an earlier commit [https://github.com/amiller/tahoe-lafs/commit/ff8a0a593c6d6b8f1607bb908884cf233b69eaf3 ff8a0a], I introduced an error that prevented the cache from being populated correctly.
2	2
3	3	The error was something along the lines of store(H(data), data) followed by get(H'(data))->data which resulted in the cache being less effective (but not incorrect). This loss of effectiveness was succesfully detected by the test_deepcheck_cachemisses in that commit.
