rust-cpython: drop direct dependency on python(27|3)_sys We no longer use it.

rust-cpython: leverage upstreamed py_capsule_fn!() macro

rust-cpython: bump cpython crates to 0.3 Unblocks py_capsule_fn!().

rust-cpython: turn inline comments into non-doc comments

rust-cpython: fix signature of make_dirstate_tuple() Fortunately, the layout of PyObject {} is compatible with a C pointer, but we shouldn't rely on that. This also fixes the handling of NULL pointer.

rust-cpython: mark capsule function as unsafe

rust-cpython: add wrapper around decapsule_make_dirstate_tuple() There are a couple of safety issues. First, the returned function pointer must be unsafe. Second, its return value must be a raw pointer (i.e. python27_sys::PyObject), not a cpython::PyObject. The wrapper function will address these issues.

eol: don't fallback to use .hgeol from tip (BC) If no .hgeol were found in the current working directory, eol would fallback to use the one in tip. That could in some cases give very confusing or wrong behaviour when it applied wrong filters. It might be convenient to have plain 'clone' immediately apply 'native' encoding patterns in the cloned repo. But it is wrong to assume that this revision is tip, and even more wrong to also apply it when not cloning - for example when updating between history revisions. The encoding should always match the content of the current .hgeol . It should never use anything else.

eol: tweak test-eol-clone.t with better descriptions and logging Expose impact of changes coming next ...

eol: fix update - don't use and apply removed .hgeol patterns 'hg up -C' to revisions with different .hgeol patterns could leave dirty changes in the working directory. That could make deployment of new .hgeol filters tricky: they would "occasionally" apply also in branches where they shouldn't. Fixed by dropping all old patterns before applying new ones.

eol: cache needs update, also if it has same timestamp as the source Ignoring same timestamp could (in theory?) cause changes to not be detected. It might happen quite often that the cache is populated right after .hgeol has been updated and they thus have the same time stamp second. But we want correctness, and if it populates the cache so fast, then it can also not be a big problem to run it again next time when the timestamp has moved on.

eol: update isbinary filter to work without compat wrapper

localrepo: fix variable binding in handling of old filters The lambda was referencing oldfn in outer scope without binding the current value. If oldfn function were reassigned before use, wrong filters could be used. Fixed by having oldfn as named parameter default value of the lambda.

localrepo: debug log of filter name when filtering through a function

eol: test-eol-update.t coverage around update --clean using filters ... badly This will reveal problems and track their fixes.

copies: drop the findlimit logic We don't use the limit anymore so we should stop computing that limit. I did not bother measuring the potential performance gain. I am assuming that not running any code will be faster that doing some computation and not using the result.
