Revision c939d241673ad093336e936075a029127368d87e authored by Richard Hansen on 18 November 2013, 04:12:42 UTC, committed by Junio C Hamano on 18 November 2013, 21:45:56 UTC
The internal mercurial API expects ordinary 8-bit string objects, not Unicode string objects. With this change, the test-hg.sh unit tests pass again.

/*
* 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(indegee, 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.
*
* - 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 id initialied by the variant without "_with_stride" associates
* each commit with an array of one integer.
