tags: don't check for clean files when checking for dirty working copy We didn't request status for clean files so there should never be any entries in the list of clean files (at least not since dd773340a085), but it's misleading to check the list.

branchmap: make "closed" a set from beginning instead of converting from list Differential Revision: https://phab.mercurial-scm.org/D7427

debugextensions: gracefully handle missing __file__ attributes This was crashing PyOxidizer. Differential Revision: https://phab.mercurial-scm.org/D7452

debuginstall: gracefully handle missing __file__ attributes This was crashing PyOxidizer. While here, point "Python lib" and "installed modules" to the oxidized binary when read from memory instead of pretending their location is unknown. Differential Revision: https://phab.mercurial-scm.org/D7451

typing: add pseudo localstr.__init__() to help pytype Apparently, pytype failed to parse localstr.__new__()? This fixes the following errors: line 126, in __hash__: No attribute '_utf8' on localstr [attribute-error] line 188, in tolocal: Function localstr.__init__ was called with the wrong arguments [wrong-arg-types] Expected: (self, string: str, ...) Actually passed: (self, string: bytes, ...)

typing: fix argument type of encoding.localstr() It takes both utf-8 and local strings in bytes type.

typing: suppress error of py2 encoding.strtolocal() and .strfromlocal() I don't know how to conditionally get rid of these py2/py3 overloads from .pyi file. Instead, this patch makes pytype ignore the false-positives: line 271, in strtolocal: bad option in return type [bad-return-type] Expected: bytes Actually returned: str

typing: constrain argument/return types of encoding.toutf8b()

typing: fix argument type of encoding.tolocal() and .fromutf8b() Fixes various pytype errors.

typing: fix forward reference in _Tlocalstr type bound AFAIK, a quoted string in type position is translated to its ForwardRef. https://github.com/python/typing/issues/34 This fixes the following error: File "mercurial/encoding.py", line 38, in <module>: Name 'localstr' is not defined [name-error]
