* Fix calling parse_pathspec with no paths nor PATHSPEC_PREFER_* flagsNguyễn Thái Ngọc Duy2013-10-22
| | | | | | | | | | | | | | | | | | | When parse_pathspec() is called with no paths, the behavior could be either return no paths, or return one path that is cwd. Some commands do the former, some the latter. parse_pathspec() itself does not make either the default and requires the caller to specify either flag if it may run into this situation. I've grep'd through all parse_pathspec() call sites. Some pass neither, but those are guaranteed never pass empty path to parse_pathspec(). There are two call sites that may pass empty path and are fixed with this patch.

* Update :/abc ambiguity checkNguyễn Thái Ngọc Duy2013-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | :/abc may mean two things: - as a revision, it means the revision that has "abc" in commit message. - as a pathpec, it means "abc" from root. Currently we see ":/abc" as a rev (most of the time), but never see it as a pathspec even if "abc" exists and "git log :/abc" will gladly take ":/abc" as rev even it's ambiguous. This patch makes it: - ambiguous when "abc" exists on worktree - a rev if abc does not exist on worktree - a path if abc is not found in any commits (although better use "--" to avoid ambiguation because searching through commit DAG is expensive) A plus from this patch is, because ":/" never matches anything as a rev, it is never considered a valid rev and because root directory always exists, ":/" is always unambiguously seen as a pathspec.
