histedit: rename variables so they have "ctx" in them It is convention for context instances to end with "ctx." Until we have type annotations, this makes auditing much, much easier. Differential Revision: https://phab.mercurial-scm.org/D2425

cmdutil: use ctx.rev() instead of int(ctx) Continuing to wean off basectx.__int__. Differential Revision: https://phab.mercurial-scm.org/D2424

templatekw: use ctx.rev() instead of casting context to int basectx has __int__ implemented. Per mailing list discussion with Yuya, we don't like having this implemented because it is too much magic and in some cases rev() will return None, which isn't an int. So convert a `'%d' % ctx` to ctx.rev() instead. Differential Revision: https://phab.mercurial-scm.org/D2423

py3: fix handling of keyword arguments at more places The keys of keyword arguments of Python 3 should be str, which is why we need to prevent getting the b'' prefix added by the transformer or convert keys to str using pycompat.strkwargs() Differential Revision: https://phab.mercurial-scm.org/D2420

setup: only allow Python 3 from a source checkout (issue5804) People are running `pip install Mercurial` with Python 3 and that is working because not everything performs a Python version compatibility check. Modern versions of pip do recognize the "python_requires" keyword (https://packaging.python.org/tutorials/distributing-packages/#python-requires) which we set if using setuptools. But this isn't set nor recognized everywhere. To prevent people from accidentally installing Mercurial with Python 3 until Python 3 is officially supported, have setup.py fail when run with Python 3. But don't fail if we're running from a source checkout, as we don't want to anger Mercurial developers hacking on Python 3 nor Mercurial's test automation running from source checkouts. People running setup.py from source checkouts could still fall through a Python 3 crack. But at least the `pip install Mercurial` attempt will get nipped in the bud.

tests: add HTTP POST and PUT support to the $LOGDATE$ substitution The lfs serving code uses both POST and PUT requests (and there's existing support for POST).

cleanup: say goodbye to manifestv2 format This experiment was a bust: we'd hoped for smaller repository sizes, but things got larger. Google ended up rolling out tree manifests in a format that's compatible with the original manifest format, and I believe Facebook is doing the same. This code was never implemented as native speedups, so I'm pretty comfortable saying nobody is using the experimental feature. Let's rip it out. I noticed this code still kicking around because I was investigating a repo corruption issue for timeless. .. bc:: Support for the experimental manifestv2 format has been removed, as it was never completed and failed to meet expectations.

wireproto: document the wonky push protocol for SSH It took me several minutes to figure out how the "unbundle" protocol worked. It turns out that the SSH protocol handler sends an empty reply that is interpreted as "OK to send" and only then does the client send the bundle payload. On top of that, the response is different depending on whether the operation was successful or not. I nearly pulled out my hair deciphering this.
