merge: don't pay for pathconflicts if there are none

pathauditor: no need to normcase the paths The only thing normed paths are used is the key of the caching sets, so the only change of behavior will be that the checks will be repeated for paths that differ by case. If anything, it seems correct for the check to be repeated, in case that actually affects semantics, but the main reasoning is simplifying the code and making it a bit faster. It looks like the code originally comes from commit [081e795c60e0]: it looks like that commit tried to get rid of the existing norming, but presumably did this overly cautiously, preserving it for the cache keys, even though it was pointless even then.

pathutil: slightly faster path audit in the common case

debug: add a config to abort update early This is useful to benchmark the parts of [hg update] that come before the parallel worker.

dirstate: add missing methods and kwargs to idirstate interface

dirstate: swap pathto() and get_entry() in idirstate This way the order of methods in dirstate and idirstate classes is the same. Just to make it easier to use diff tools to compare the two classes.

dirstate: update docstrings in idirstate from the current dirstate

setup: drop legacy osx compiler tuning to enable universal builds This was triggering deprecation warnings about migrating to `packaging.version` from `distutils` Version classes with `make local`. But rather than migrate that code, let's just get rid of some ~10-12 year old workarounds. As a bonus, the cext libraries that are built are now universal binaries containing x86_64 and arm64 images (at least when built on macOS 11.4 with Xcode 12.5 and the universal version of Python 3.9.13). Several things to note here: - Apple dropped support for 10.15 in Nov 2022, and OS X Lion that is referenced is 10.7 (unsupported since late 2014) - `xcode4` was basically always True because of the `>=` check (10.8 used Xcode 5, and I have Xcode 10.2 on 10.14) - `xcode51` was always False for modern-ish Xcode, because of the exact version string matching - Python 3.8 only supports OS X 10.9+; the Python 3.9.1+ universal installer is macOS 11+ only, and Python 3.10 drops the x86_64 installer to deliver only the universal installer. All of this is to say, the only thing lost by dropping this code on modern Xcode is that `os.environ['ARCHFLAGS'] = ''` is no longer set. But we probably shouldn't be setting that anymore, as shown by the universal libraries now being generated. I was able to `make local` and `python3 run-tests.py --local` with python 3.9.9, Xcode 10.2, and macOS 10.14.6, and didn't incur any more than the usual few test errors, so this should still work on some older versions of macOS.

tests: simplify `(py3 no-py36 !)` output matching predicates to `(no-py36 !)` It's all py3 now.

tests: drop `(py3 !)` output matching predicates Presumably these were paired with `(no-py3 !)` at one point, but now they were unconditionally true. test-check-code.t required a couple of `(glob)` markers on the changed lines in test-lfs-serve-access.t, because of the `$LOCALIP` usage on those lines. Not sure how those lines slipped through the checks previously.

run-tests: drop a workaround for python2 The problem is only on python3, but the awkward handling was because python2 didn't have this exception type. I've sporadically seen it running in WSL, but no clue what it means.

contrib: drop py2 support from testparseutil.py

tests: drop py2 support from `f` utility

tests: drop py2 support from test-doctest.py

tests: drop py2 support from test-demandimport.py

tests: optional PEP 657 error location in test-lfs-serve-access.t (issue6782)

tests: optional PEP 657 error location in test-extension.t (issue6781)

tests: filter out PEP 657 error locations in tracebacks (issue6780) https://docs.python.org/3/whatsnew/3.11.html#whatsnew311-pep657

pytype: add coverage for parts of hgext There are tons of things to fix here (which have been blacklisted for now), but this should help prevent further regressions.

convert: stop passing str to the dateutil API in darcs I'm sure there's a bunch more stuff in here that's broken, but this was flagged by pytype.

typing: suppress a couple of attribute-errors in convert I thought these might be real issues, but they're not.

hooklib: force an exception wrapped by errors.Abort to bytestr Flagged by PyCharm and pytype.

notify: force an exception wrapped by errors.Abort to bytestr Flagged by PyCharm and pytype.

typing: disable a bogus attribute-error warning in phabricator In a local pytype run, this fixes: File "/mnt/c/Users/Matt/hg/hgext/phabricator.py", line 359, in <lambda>: No attribute 'items' on bytes [attribute-error] In Union[Any, bytes] Called from (traceback): line 363, in process The `bytes` case takes the previous `if` branch though.

sparse: fix a py2 based usage of `map()` In a local pytype run, this fixes: File "/mnt/c/Users/Matt/hg/hgext/sparse.py", line 386, in debugsparse: unsupported operand type(s) for item retrieval: 'fcounts: Iterator[int]' and '0: int' [unsupported-operands] No attribute '__getitem__' on 'fcounts: Iterator[int]' File "/mnt/c/Users/Matt/hg/hgext/sparse.py", line 387, in debugsparse: unsupported operand type(s) for item retrieval: 'fcounts: Iterator[int]' and '1: int' [unsupported-operands] No attribute '__getitem__' on 'fcounts: Iterator[int]' File "/mnt/c/Users/Matt/hg/hgext/sparse.py", line 388, in debugsparse: unsupported operand type(s) for item retrieval: 'fcounts: Iterator[int]' and '2: int' [unsupported-operands] No attribute '__getitem__' on 'fcounts: Iterator[int]'

typing: adjust `mercurial.util.iterlines()` to accept any `Iterable` In a local pytype run on the extensions, this fixes: File "/mnt/c/Users/Matt/hg/hgext/phabricator.py", line 788, in maketext: Function mercurial.util.iterlines was called with the wrong arguments [wrong-arg-types] Expected: (iterator: Iterator[bytes]) Actually passed: (iterator: list) Attributes of protocol Iterator[bytes] are not implemented on list: __next__

typing: disable an attribute-error warning in the journal extension The code is complicated enough that pytype doesn't realize that `name` can't be `None` if it is evaluated here.

remotefilelog: byteify the message for a few StorageErrors Flagged by pytype locally.

histedit: byteify the help for the multifold action While there's some allowance for str in `_()`, it's commented to be for "goofy unicode docstrings in test", so no idea how well that works, but it should at least come back as bytes. With HGPLAIN, however, the str isn't touched and is returned as-is, so this seems like a real bug.

typing: disable a few incorrect warnings in pywatchman The module-attr warnings are for things that only exist on Windows, and the wrong-keyword-args warning is due to a special case for a specific constructor. Both of these are properly conditionalized.
