phases: stop modifying localrepo in readroots() phasedefaults is also passed explicitely to help the casual reader understand where it is used without grepping all the sources.

phases: call filterunknown() in readroots() One less function manipulating localrepo state.

repair: no need to call filterunknown() in strip() Calling strip() will eventually trigger localrepo.destroyed() which will invalidate _parseroots. It will call filterunknown() upon reload. Changes to test-keyword.t are related to commit --debug running after either qpop or rollback.

test-phases: test changing null revision phase The behaviour is correct but for bad reasons: the repo.set() call in phase command fails for '-1'. It should be rejected explicitely by phase boundary commands, sadly this is hard to do because phase changes are not applied atomically.

merge with stable

tests: fix test-parseindex2.py when run with --pure

changelog: ensure that nodecache is valid (issue3428) This ensures that an out-of-process hook can see an incoming changegroup.

parsers: change the type of nt_level We should generally prefer Py_ssize_t whenever we are talking about lengths.

parsers: change the type signature of hexdigit An upcoming change will make use of this.

parsers: allow nt_find to signal an ambiguous match

parsers: factor out radix tree initialization

parsers: update ntrev when we stop scanning This prevents us from inserting some nodes twice, wasting work.
