exchange: eliminate some bytes.format() calls Differential Revision: https://phab.mercurial-scm.org/D7511

windows: suppress pytype warnings for Windows imports and functions This should allow the modules to not be excluded, and not generate complaints on non Windows platforms. Differential Revision: https://phab.mercurial-scm.org/D7510

changectx: mark the parents of the working copy as non filtered If we successfully accessed the working copy, its parents are not filtered. Differential Revision: https://phab.mercurial-scm.org/D7491

repoview: add an explicit set of all filter that show the wc parents The `visible` set will always show the working copy parents. We record this in a specific set. This will allow to fast path some access. Differential Revision: https://phab.mercurial-scm.org/D7490

localrepo: introduce a `_quick_access_changeid` property Having faster access to `null` is cute… but limited. We want to speedup access to more useful revision, like `.`. We start with turning the fast path for `null` into something more generic. Differential Revision: https://phab.mercurial-scm.org/D7488

changectx: use unfiltered changelog to access parents of unfiltered revs If a revision is not filtered, we know that its parents are not either. So we can take a shortcut. This shortcut avoid the computation of all filtered revs in some cases. Differential Revision: https://phab.mercurial-scm.org/D7487

locarepo: also fastpath `nullid` lookup in __getitem__ We already use that fastpath for `"null"` and `nullrev`, using it for `nullid` is similar. Differential Revision: https://phab.mercurial-scm.org/D7486

repoview: add more tests to track operation not supposed to trigger filtering This test is useful to confirm we removed filtering trigger and to prevent it to come back without us noticing. The commands tested in the test were initially introduced one by one. However, on Martin von Zweigbergk request, we are adding them all at once.
