mmap_limit: introduce GIT_MMAP_LIMIT to allow testing expected mmap size
In order to test expectations about mmap in a way similar to testing expectations about malloc with GIT_ALLOC_LIMIT introduced by d41489a6 (Add more large blob test cases, 2012-03-07), introduce a new environment variable GIT_MMAP_LIMIT to limit the largest allowed mmap length. xmmap() is modified to check the size of the requested region and fail it if it is beyond the limit. Together with GIT_ALLOC_LIMIT tests can now confirm expectations about memory consumption. Signed-off-by: Steffen Prohaska <prohaska@zib.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
