 alloc: add GIT_DEBUG_STRICT_ALLOC 2021-07-19T19:41:44+00:00 Edward Thomson ethomson@edwardthomson.com 2021-07-19T19:41:44+00:00 48e6b02be9b0639fdc25e17514f11d7ef141dfbc Add `GIT_DEBUG_STRICT_ALLOC` to help identify problematic callers of allocation code that pass a `0` size to the allocators and then expect a non-`NULL` return. When given a 0-size allocation, `malloc` _may_ return either a `NULL` _or_ a pointer that is not writeable. Most systems return a non-`NULL` pointer; AIX is an outlier. We should be able to cope with this AIXy behavior, so this adds an option to emulate it.

allocators: move standard allocator into subdirectory 2019-02-21T11:28:02+00:00 Patrick Steinhardt ps@pks.im 2019-02-21T11:13:59+00:00 b63396b75fe26afa3b27259c0d13dd7bc13b53ba Right now, our two allocator implementations are scattered around the tree in "stdalloc.h" and "win32/w32_crtdbg_stacktrace.h". Start grouping them together in a single directory "allocators/", similar to how e.g. our streams are organized.
