py3: use '%d' instead of '%s' for integers Differential Revision: https://phab.mercurial-scm.org/D856

py3: use pycompat.strkwargs() before passing a dict as keyword argument Differential Revision: https://phab.mercurial-scm.org/D854

py3: return False early while checking whether None is a key in lazymanifest In this patch we returns False early if we are trying to check whether None is a key in lazymanifest. The reason I added a diff is that on Python 3, it goes into the lazy manifest code an returns a TypeError. I checked with Durham that whether None can be a possible key in lazymanifest and he said "no". So it's safe to have this if statement. This fixes `hg merge` on Python 3.

dirstate: use keyword arguments to clarify status()'s callers The arguments are especially non-obvious because the order is different from dirstate.walk(). Differential Revision: https://phab.mercurial-scm.org/D847

perf: remove fallbacks to ancient versions of dirstate.walk() If the call to dirstate.walk() failed, we would try to fall back to older versions. These were removed in d3d1d39da2fa (walk: remove cmdutil.walk, 2008-05-12) and f8299c84b5b6 (dirstate: fold statwalk and walk, 2008-06-26). We don't care about testing performance of versions that old versions at this point, so let's clean up. Differential Revision: https://phab.mercurial-scm.org/D845

releasenotes: update docstrings with information on additional flags This patch adds documentation related to the two new flags --check and --list for releasenotes extension. Differential Revision: https://phab.mercurial-scm.org/D544

releasenotes: raise error on simultaneous usage of flags The releasenotes command is supposed to raise an error when --list and --rev/--check flags are used together. This patch adds the above functionality. Differential Revision: https://phab.mercurial-scm.org/D831

dirstate: move parents source of truth to dirstatemap As part of moving dirstate storage to its own class, let's move the source of truth for the dirstate parents to dirstatemap. This requires that dirstate._pl no longer be a cache, and that all sets go through dirstatemap.setparents. Differential Revision: https://phab.mercurial-scm.org/D759

dirstate: move parent reading to the dirstatemap class As part of moving dirstate storage logic to a separate class, let's move the function that reads the parents from the file. This will allow extensions to write dirstate's that store the parents in other ways. Differential Revision: https://phab.mercurial-scm.org/D758
