I looped over the toplevel header files, creating a temporary two-line C program for each consisting of #include "git-compat-util.h" #include $HEADER This patch is the result of manually fixing errors in compiling those tiny programs.

/*

* During list-object traversal we allow certain objects to be
|
|
* filtered (omitted) from the result. The active filter uses
|
|
* these result values to guide list-objects.
|
|
*
|
|
* _ZERO : Do nothing with the object at this time. It may
|
|
* be revisited if it appears in another place in
|
|
* the tree or in another commit during the overall
|
|
* traversal.
|
|
*
|
|
* _MARK_SEEN : Mark this object as "SEEN" in the object flags.
|
|
* This will prevent it from being revisited during
|
|
* the remainder of the traversal. This DOES NOT
|
|
* imply that it will be included in the results.
|
|
*
|
|
* _DO_SHOW : Show this object in the results (call show() on it).
|
|
* In general, objects should only be shown once, but
|
|
* this result DOES NOT imply that we mark it SEEN.
|
|
*
|
|
* Most of the time, you want the combination (_MARK_SEEN | _DO_SHOW)
|
|
* but they can be used independently, such as when sparse-checkout
|
|
* pattern matching is being applied.
|
|
*
|
|
* A _MARK_SEEN without _DO_SHOW can be called a hard-omit -- the
|
|
* object is not shown and will never be reconsidered (unless a
|
|
* previous iteration has already shown it).
|
|
*
|
|
* A _DO_SHOW without _MARK_SEEN can be used, for example, to
|
|
* include a directory, but then revisit it to selectively include
|
|
* or omit objects within it.
|
|
*
|
|
* A _ZERO can be called a provisional-omit -- the object is NOT shown,
|
|
* but *may* be revisited (if the object appears again in the traversal).
|
|
* Therefore, it will be omitted from the results *unless* a later
|
|
* iteration causes it to be shown.
