define_shared_commit_slab() could be used in a header file to define a commit-slab. One of these C files must include commit-slab-impl.h and "call" implement_shared_commit_slab(). Signed-off-by: Junio C Hamano <gitster@pobox.com>

/*
|
|
* define_commit_slab(slabname, elemtype) creates boilerplate code to define
|
|
* a new struct (struct slabname) that is used to associate a piece of data
|
|
* of elemtype to commits, and a few functions to use that struct.
|
|
*
|
|
* After including this header file, using:
|
|
*
|
|
* define_commit_slab(indegree, int);
|
|
*
|
|
* will let you call the following functions:
|
|
*
|
|
* - int *indegree_at(struct indegree *, struct commit *);
|
|
*
|
|
* This function locates the data associated with the given commit in
|
|
* the indegree slab, and returns the pointer to it. The location to
|
|
* store the data is allocated as necessary.
|
|
*
|
|
* - int *indegree_peek(struct indegree *, struct commit *);
|
|
*
|
|
* This function is similar to indegree_at(), but it will return NULL
|
|
* until a call to indegree_at() was made for the commit.
|
|
*
|
|
* - void init_indegree(struct indegree *);
|
|
* void init_indegree_with_stride(struct indegree *, int);
|
|
*
|
|
* Initializes the indegree slab that associates an array of integers
|
|
* to each commit. 'stride' specifies how big each array is. The slab
|
|
* that is initialized by the variant without "_with_stride" associates
|
|
* each commit with an array of one integer.
|
|
*
|
|
* - void clear_indegree(struct indegree *);
|
|
*
|
|
* Empties the slab. The slab can be reused with the same stride
|
|
* without calling init_indegree() again or can be reconfigured to a
|
|
* different stride by calling init_indegree_with_stride().
|
|
*
|
|
* Call this function before the slab falls out of scope to avoid
|
|
* leaking memory.
