17 See glossary-context.txt for the syntax of pathspec. In memory, a
18 pathspec set is represented by "struct pathspec" and is prepared by
19 parse_pathspec(). This function takes several arguments:
21 - magic_mask specifies what features that are NOT supported by the
22 following code. If a user attempts to use such a feature,
23 parse_pathspec() can reject it early.
25 - flags specifies other things that the caller wants parse_pathspec to
28 - prefix and args come from cmd_* functions
30 parse_pathspec() helps catch unsupported features and reject them
31 politely. At a lower level, different pathspec-related functions may
32 not support the same set of features. Such pathspec-sensitive
33 functions are guarded with GUARD_PATHSPEC(), which will die in an
34 unfriendly way when an unsupported feature is requested.
36 The command designers are supposed to make sure that GUARD_PATHSPEC()
37 never dies. They have to make sure all unsupported features are caught
38 by parse_pathspec(), not by GUARD_PATHSPEC. grepping GUARD_PATHSPEC()
39 should give the designers all pathspec-sensitive codepaths and what
40 features they support.
42 A similar process is applied when a new pathspec magic is added. The
43 designer lifts the GUARD_PATHSPEC restriction in the functions that
44 support the new magic. At the same time (s)he has to make sure this
45 new feature will be caught at parse_pathspec() in commands that cannot
46 handle the new magic in some cases. grepping parse_pathspec() should
