Patrick Steinhardt 94af9155 2017-03-20T09:01:18 map: remove `*map_free` macros The `map_free` functions were not implemented as functions but instead as macros which also set the map to NULL. While this is most certainly sensible in most cases, we should prefer the more obvious behavior, namingly leaving the map pointer intact. Furthermore, this macro has been refactored incorrectly during the map-refactorings: the two statements are not actually grouped together by a `do { ... } while (0)` block, as it is required for macros to match the behavior of functions more closely. This has led to at least one subtle nesting error in `pack-objects.c`. The following code block ``` if (pb->object_ix) git_oidmap_free(pb->object_ix); ``` would be expanded to ``` if (pb->object_ix) git_oidmap__free(pb->object_ix); pb->object_ix = NULL; ``` which is not what one woudl expect. While it is not a bug here as it would simply become a no-op, the wrong implementation could lead to bugs in other occasions. Fix this by simply removing the macro altogether and replacing it with real function calls. This leaves the burden of setting the pointer to NULL afterwards to the caller, but this is actually expected and behaves like other `free` functions.

Vicent Marti ef8b7feb 2015-12-16T19:36:50 index: Also size-hint the hash table Note that we're not checking whether the resize succeeds; in OOM cases, we let it run with a "small" vector and hash table and see if by chance we can grow it dynamically as we insert the new entries. Nothing to lose really.
