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

hgweb: don't use raw string for session vars This r'' is leaking into the templating layer and causing an assertion failure. The r'' was added in d1fccbd50fcd (October 2017). Similar code in hgweb_mod.py was also changed in that changeset. hgweb_mod.py was updated in ec46415ed826 (March 2018) to use webutil.sessionvars(), which doesn't use raw strings.

tests: normalize to bytes in test-install.t directory() was returning str and hgdirectory() was returning bytes. This made the set compare fail. Let's normalize the types on Python 3 so the test passes. Differential Revision: https://phab.mercurial-scm.org/D5650

config: reject str sections and keys on Python 3 Otherwise we could end up with a dict having both the str and bytes versions of a particular config item. This may cause some tests to regress. I haven't checked. But it is better behavior to fail fast. We could just as easily change this to normalize the values. But I like catching all non-compliant call sites first.

httppeer: use %s for formatting This prevents a b'' from appearing in Python 3 output. We keep the single quotes for backwards compatibility. Differential Revision: https://phab.mercurial-scm.org/D5647
