Revision f0583867e746985e9d62f57d5ba6ce27b2603447 authored by Michał Kiedrowicz on 18 April 2009, 21:03:57 UTC, committed by Junio C Hamano on 20 April 2009, 20:47:02 UTC 
tests: make test-apply-criss-cross-rename more robust
 
I realized that this test does check if git-apply succeeds, but doesn't
tell if it applies patches correctly. So I added test_cmp to check it.

I also added a test which checks swapping three files.

/*
 * These are some simple generic hash table helper functions.
 * Not necessarily suitable for all users, but good for things
 * where you want to just keep track of a list of things, and
 * have a good hash to use on them.
 *
 * It keeps the hash table at roughly 50-75% free, so the memory
 * cost of the hash table itself is roughly
 *
 *	3 * 2*sizeof(void *) * nr_of_objects
 *
 * bytes.
 *
 * FIXME: on 64-bit architectures, we waste memory. It would be
 * good to have just 32-bit pointers, requiring a special allocator
 * for hashed entries or something.
