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
