rust: error for WdirUnsupported with cpython conversion as exception This introduces WorkingDirectoryUnsupported as an enum variant of GraphError in the core and converts it to the expected `mercurial.error.WdirUnsupported`.

rust: working directory revision number constant This introduces the constant, but does not use it anywhere yet.

py3: fix test-update-atomic.t The .replace('o', '') hack on oct() return value is required because: % python -c 'print(oct(10))' 012 % python3 -c 'print(oct(10))' 0o12 Differential Revision: https://phab.mercurial-scm.org/D5684

py3: fix test-newcgi.t Differential Revision: https://phab.mercurial-scm.org/D5683

py3: fix up test-encoding-align.t for python3 I'm not super thrilled with how this reads, but the original didn't thrill me either. Differential Revision: https://phab.mercurial-scm.org/D5682

py3: these two casefolding tests pass for me on my Mac I assume the buildbot didn't catch them because it's on a case-sensitive filesystem. Differential Revision: https://phab.mercurial-scm.org/D5681

py3: port test-bugzilla.t to Python 3 Some assorted fixes required in the extension itself, all around bytes/str issues. Differential Revision: https://phab.mercurial-scm.org/D5680

uncommit: set dirstateparents from within _fixdirstate() It's now done in the same way for uncommit and unamend, so we can share the code. Differential Revision: https://phab.mercurial-scm.org/D5662

unamend: fix unamending of renamed rename Before this patch, we were passing in the result of a status call for a different set of commits than what we calculated copies for, which seemed suspicous to me. The rewritten version gets status and copy information from the same sets of commits. Differential Revision: https://phab.mercurial-scm.org/D5661

uncommit: mark old node obsolete after updating dirstate The next patch will start doing more things with the context object for the old node and that ran into problems without this change. Regardless of that, I think it seems better to first update to the new node and then mark the old node obsolete. Differential Revision: https://phab.mercurial-scm.org/D5660

unamend: import "copies" module as "copiesmod" to avoid shadowing Differential Revision: https://phab.mercurial-scm.org/D5659

tests: add more tests of uncommit/unamend with copies The unamend tests show suboptimal behavior. Differential Revision: https://phab.mercurial-scm.org/D5658

tests: clean up after each test in test-unamend.t Differential Revision: https://phab.mercurial-scm.org/D5657

cleanup: use clang-tidy to add missing {} around one-line statements I find this easier to read. Cleanup performed like this: hg files 'set:(**.c or **.cc or **.h) and not "listfile:contrib/clang-format-ignorelist"' | while read f ; do clang-tidy -fix -checks=readability-braces-around-statements $f -- $(python-config --cflags) -Imercurial/cext -Imercurial done make format-c I had to revert chg/chg.c as it's got a construct that seems to confuse clang-tidy, so I'll work on that file later if this change is acceptable. I only tackle files that are under clang-format's authority because otherwise I'd have to do a bunch of manual formatting. A few files didn't get edited because clang-tidy couldn't find some headers. Again, I'll figure that out later assuming this change is accepted. No check-code rule added for now because writing the regex sounds hard. In a perfect world I guess we could write a test that uses clang-tidy on these files, but I think clang-tidy is pretty rarely installed. :/ Differential Revision: https://phab.mercurial-scm.org/D5675

py3: port test-batching.py to python3 I used byteify-strings.py on this file, then manually added the various pycompat and bprint bits as needed. Differential Revision: https://phab.mercurial-scm.org/D5678

py3: fix missing b prefixes in test-arbitraryfilectx.t Test passes on Python 3. # skip-blame b prefixes Differential Revision: https://phab.mercurial-scm.org/D5679

py3: add missing b prefixes in test-acl.t There's one failure left in the test, which looks like a real problem around executing hooks. I have not investigated further. # skip-blame as just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D5677

py3: buildbot found more passing tests, thanks to indygreg for most of them Differential Revision: https://phab.mercurial-scm.org/D5676

tests: drop a duplicate definition of a constant Differential Revision: https://phab.mercurial-scm.org/D5663

tests: support URL quoting on Python 3 We could use mercurial.urllibcompat, but meh. This makes things easier to read. The test still fails on Python 3 for some reason. But at least we no longer have an exception. Differential Revision: https://phab.mercurial-scm.org/D5669

tests: write directly to stdout to avoid b'' prefixes This enables the test to pass on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5668

tests: handle string escaping/encoding on Python 3 This code was failing on Python 3 for a few reasons: 1) sys.argv is str and str doesn't have a .decode() 2) the "string_escape" encoding was renamed to "unicode_escape" It is wonky casting to bytes to str to bytes. But this is test code, so meh. I don't believe we exercise any code paths in these tests where the arguments aren't ascii. Differential Revision: https://phab.mercurial-scm.org/D5667

convert: use raw strings for XML strings Due to the source transformer, we were passing bytes into the XML APIs. This results in not finding elements and doing compares against mismatched types. Use raw string literals so we use str everywhere. Differential Revision: https://phab.mercurial-scm.org/D5664

tests: normalize XML values to bytes This fixes some type mismatches. The encoding shouldn't matter for what this script is used for. UTF-8 seems reasonable, especially since I'm pretty sure SVN will emit UTF-8 encoded XML. Differential Revision: https://phab.mercurial-scm.org/D5665

hgweb: ensure template mapping keys are bytes Before, str keys were being added in Python 3 because named arguments to dict() use native str for keys. This caused the templater to fail to find the keys since it was looking for bytes versions. This makes a handful of tests pass on Python 3. We may want to consider having the templater validate that keys in mapping dicts are bytes. But I'm unsure whether this is appropriate and won't be doing this.

remotefilelog: use %d to format an int Differential Revision: https://phab.mercurial-scm.org/D5656

tests: use bytes for file I/O Otherwise we get various type mismatches. Differential Revision: https://phab.mercurial-scm.org/D5655

tests: make filenames bytes for Python 3 I also snuck a %s -> %d in there to appease Python 3. Differential Revision: https://phab.mercurial-scm.org/D5654

tests: use assertEqual() This avoids a deprecation warning under at least Python 3.7. Differential Revision: https://phab.mercurial-scm.org/D5653

tests: add setsockopt() output on Python 3 Python 3 appears to call setsockopt() where Python 2 did not. Differential Revision: https://phab.mercurial-scm.org/D5652
