Revision 58696bfcaacc50323e596112124b41242fde23de authored by Junio C Hamano on 08 July 2024, 22:52:11 UTC, committed by Junio C Hamano on 08 July 2024, 23:23:05 UTC
Under ci/ hierarchy, we run scripts under either "sh" (any Bourne
compatible POSIX shell would work) or specifically "bash" (as they
require features from bash, e.g., ${parameter/pattern/string}
expansion). As we have the CI environment under our control, we can
expect that /bin/sh will always be fine to run the scripts that only
require a Bourne shell, but we may not know where "bash" is
installed depending on the distro used.
So let's make sure we start these scripts with either one of these:
#!/bin/sh
#!/usr/bin/env bash
Yes, the latter has to assume that everybody installs "env" at that
path and not as /bin/env or /usr/local/bin/env, but this currently
is the best we could do.

/*
* 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
* if the location to store the data associated with the given commit
* has not been allocated yet.
* Note that the location to store the data might have already been
* allocated even if no indegree_at() call has been made for that commit
* yet; in this case this function returns a pointer to a
* zero-initialized location.
*
* - 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.
*
* - void deep_clear_indegree(struct indegree *, void (*free_fn)(int*))
*
* Empties the slab, similar to clear_indegree(), but in addition it
* calls the given 'free_fn' for each slab entry to release any
* additional memory that might be owned by the entry (but not the
* entry itself!).
* Note that 'free_fn' might be called even for entries for which no
* indegree_at() call has been made; in this case 'free_fn' is invoked
* with a pointer to a zero-initialized location.
