Besides leaking the complete khash namespace into files wherever khashes are used, this also triggers Clang's -Wunused-function warnings when some of the static functions are not being used at all. Fix the issue by moving the includes into the respective map implementation files. Add forward declares for all the map types to make them known.
5bfb3b58	2018-11-23T18:48:40	khash: implement map-specific foreach macros The current foreach map macros simply redirect to the type-indifferent `kh_foreach` macro. As this type-indifferent macro directly accesses the structures, the current implementation makes it impossible to make the stuctures private to the implementation only. And making them private is required to move out the khash include into the implementations to decrease the namespace leak.
382b668b	2018-11-23T18:38:18	khash: implement begin/end via functions instead of macros Right now, the `git_map_begin()` and `git_map_end()` helpers are implemented via macros which simply redirect to `kh_begin` and `kh_end`. As these macros refer to members of the map structures, they make it impossible to move the khash include into the implementation files. Implement these helpers as real functions instead to further decouple the headers from implementations.
0c7f49dd	2017-06-30T13:39:01	Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.
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.
