Subject: [PATCH v2 09/46] parse_pathspec: add special flag for max_depth feature
Date: Sun, 14 Jul 2013 15:35:32 +0700 [thread overview]
Message-ID: <1373790969-13000-10-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1373790969-13000-1-git-send-email-pclouds@gmail.com>
match_pathspec_depth() and tree_entry_interesting() check max_depth
field in order to support "git grep --max-depth". The feature
activation is tied to "recursive" field, which led to some unwanted
activation, e.g. 5c8eeb8 (diff-index: enable recursive pathspec
matching in unpack_trees - 2012-01-15).
This patch decouples the activation from "recursive" field, puts it in
"magic" field instead. This makes sure that only "git grep" can
activate this feature. And because parse_pathspec knows when the
feature is not used, it does not need to sort pathspec (required for
max_depth to work correctly). A small win for non-grep cases.
Even though a new magic flag is introduced, no magic syntax is. The
magic can be only enabled by parse_pathspec() caller. We might someday
want to support ":(maxdepth:10)src." It all depends on actual use
cases.
max_depth feature cannot be enabled via init_pathspec() anymore. But
that's ok because init_pathspec() is on its way to /dev/null.
