bundle2: fix an off-by-one in debug message of number of parts Differential Revision: https://phab.mercurial-scm.org/D6850

tests: move a config write to top of file since it applies to all tests I'm about to add another test that depends on this config. Differential Revision: https://phab.mercurial-scm.org/D6849

idirstate: group private methods and attrs that are in the interface This makes it a little more obvious at a glance what work is left. Fortunately there's not a whole lot left. I suspect the ignore logic is going to be the tricky bit. Differential Revision: https://phab.mercurial-scm.org/D6839

interfaces: introduce an interface for dirstate implementations As usual with adding interface definitions, this describes the way things are, not the way we'd like things to be. There are some clear problems in the interface right now (eg ._map leaks in a few places), but I have plans to clean those up. There are also many missing docstrings, but again, we'll make a second pass to clean that up. Differential Revision: https://phab.mercurial-scm.org/D6836

cleanup: fix leakage of dirstate._map to client code We already had proper accessors for most of the behavior of dirstate._map that callers cared about exposed in the actual dirstate class as public methods. Sigh. There are two remaining privacy violations in the codebase after this change: 1) In the perf extension, which I suspect has to stick around because it's really testing the dirstate implementation directly 2) In largefiles, where we deal with standins and mutating status. Looking at this, I _strongly_ suspect a formal dirstate interface would allow this to work via composition instead of inheritance and monkeypatching. Fortunately, such wins are a part of my motivation for this work. I anticipate we'll come back to this in due time. Differential Revision: https://phab.mercurial-scm.org/D6837

highlight: fix encoding issues to enable Py3 compatibility This commit fixes various encoding issues with the `highlight` extension to enable compatibility with Python 3. Python `.encode()` and `.decode()` requires the target encoding to be passed as a `str`, so the value of `mercurial.encoding.encoding` must be converted before passing to the function. Pygments also assumes the `str` type for values it works with, so we must perform conversions before and after receiving values from its APIs. After applying this patch, `test-highlight.t` passes under Python 3. We add it to `python3-whitelist` as well. Tested with Pygments 2.4.2. Differential Revision: https://phab.mercurial-scm.org/D6832

hgweb: add a `message` attribute to `hgweb.common.ErrorResponse` This fixes a Python 3 bug where hgweb assumes an Exception subclass will have a `.message` attribute after running `Exception.__init__`.[1] The Python 3 way to get this info would be `e.args[0]`, but adding a new named attribute is more ergonomic in my view.
