hgweb: show as same parents as "hg parents -r REV FILE" in pages for file Before this patch, "parents" in pages for file doesn't show as same parents as "hg parents -r REV FILE", when the specified file is not modified in the specified revision. For example, it is assumed that revision A, B and D change file "f". changelog (A) ---> (B) ---> (C) ---> (D) filelog "f" (x) ---> (y) ------------> (z) "/file/D/f" invokes "webutil.parents()" with filectx(z) gotten from changectx(D), and it returns changectx(B). This is as same result as "hg parents -r D f". In the other hand, "/file/C/f" invokes "webutil.parents()" with filectx(y') gotten from changectx(C), and it returns changectx(A), because filectx(y') is linked to changectx(B), and works like filectx(y) in some cases. In this case, revision B is hidden from users browsing file "f" in revision C. This patch shows as same parents as "hg parents -r REV FILE" in pages for file, by making "webutil.parents()" return: - "linkrev()"-ed revision only, if: - specified context instance is "filectx" (because "webutil.parents()" is invoked with changectx, too), and - (1) the revision from which filectx is gotten and (2) the one to which filectx is linked are different from each other - revision gotten from "ctx.parents()", otherwise

hgweb: make "comparison" get parent from not filelog but changelog Before this patch, "comparison" shows unexpected result, when the specified file is not modified in the specified revision, even though "diff" shows empty result. When REV doesn't change specified FILE, "diff" shows: "hg diff -c REV FILE" but "comparison" shows: "hg diff -c `hg parents -r REV FILE` FILE" In other words, the former gets parent from changelog, but the latter gets one from filelog. This may confuse users browsing (and switching "diff" and "comparison" of) files in the specified revision. This patch makes "comparison" get parent from not filelog but changelog, to show "hg diff -c REV FILE" in both "diff" and "comparison" pages.

hgweb: fix lack of "bookmarks" link in "/file" page of "paper" style This patch also fixes same problem of "coal" style, because it re-uses "filerevision.tmpl" of "paper" style. "gitweb" and "monoblue" styles don't have such problems. "spartan" style doesn't have "bookmarks" page definition itself.

dirstate: report bad subdirectories as match.bad, not just a warning (BC) This seems simpler and more correct. The only test coverage for this is test-permissions.t when it says: dir: Permission denied

dirstate: improve documentation and readability of match and ignore in the walker

context: remove redundant handling of match.bad return value The 'bad' function is for reporting - it never returns anything.
