manifest: add dirs() to manifestdict Manifests should have a method of accessing its own dirs, not just the context that references the manifest. This makes it easier for other optimized versions of manifests to compute their own dirs in the most efficient way.

formatter: convert None to json null It will be used by "annotate" command to represent the workingctx revision.

localrepo: extend "changeid in repo" to return True for workingctx revision This is necessary to implement "wc" symbol for workingctx, that will be used as follows: $ hg annotate -r wc FILE In principle, "rev in repo" should be True if "repo[rev]" can return a context object. But when it was implemented by ea3acaae25bb, lookup() had a long logic to map all sorts of changeids to nodes, and "None in repo" did crash because lookup() could not accept None. So I assume that the case of changeid=None was not considered. Now "None in repo" doesn't crash, it should be True for workingctx revision. Behavior of "changeid in repo": revision "null" existing rev None (workingctx) ---------- ------ ------------ ----------------- original* True True TypeError current True True False this patch True True True (*original: ea3acaae25bb)
