py3: sort passing test list Differential Revision: https://phab.mercurial-scm.org/D4983

py3: tweak stdout writing in test-hgweb-no-path-info.t We want to write bytes for convenience. This requires sys.stdout.buffer. But using sys.stdout.buffer introducing buffered output. So we sprinkle code with sys.stdout.flush() to force immediate writes. After all that, Python 3 was emitting b'' prefixed output for errors. So we only print errors if there were some. There aren't, so b'' don't come into play and output is identical in Python 2 and 3. Differential Revision: https://phab.mercurial-scm.org/D4972

py3: use .+ instead of .* in regexp pattern Python 3.7 changed the behavior of re.sub(). See https://bugs.python.org/issue33585. The new code should work on old and new Pythons. Differential Revision: https://phab.mercurial-scm.org/D4971

py3: coerce bytestr to bytes to appease urllib.parse.quote_from_bytes() Differential Revision: https://phab.mercurial-scm.org/D4969

py3: pass str and return bytes from mimetypes.guess_type() This function wants a str (which represents a path) and returns a str. We normalize input to str and output to bytes. Differential Revision: https://phab.mercurial-scm.org/D4967

py3: use bytes literal in test-hgweb-json.t # skip-blame just b'' prefix Differential Revision: https://phab.mercurial-scm.org/D4970

py3: convert diff opcode name to bytes Differential Revision: https://phab.mercurial-scm.org/D4968

py3: byteify hgweberror.py # skip-blame just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D4966

py3: encode JSON str to bytes json.dumps() will emit UTF-8 str on Python 2 and 3. Use sysbytes to force the .encode('utf-8') on Python 3 and no-op on Python 2. Differential Revision: https://phab.mercurial-scm.org/D4965

py3: use b'' in test-check-interfaces.py # skip-blame just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D4964

revlog: optimize ancestors() to not check filtered revisions for each While reviewing the Rust implementation, I noticed iter(ancestors) doesn't need to check filtering state for each parent revision. And doing that appears to have some measurable perf win. $ hg perfancestors -R mercurial (orig) wall 0.038093 comb 0.040000 user 0.040000 sys 0.000000 (best of 100) (this) wall 0.024795 comb 0.020000 user 0.020000 sys 0.000000 (best of 117)

phabricator: drop support for the legacy phabricator.auth.token config (BC) The test for this broke in dc82ad1b7f77 when statistics started being tracked. It wasn't noticed because none of the bots have the vcr module installed. It looks like the custom_patches argument should patch in the custom httpconnection, and I can't figure out what is going on.

absorb: print '{rev}:' as a prefix to the hash I don't see a sane way to print the summary to identify the changed commit, but this at least makes it a bit easier to identify a commit when a group of them changes.

packaging: fix "make centos{5,6,7}" Without this change, make centos{5,6,7} fails with error: cp: cannot stat '<basedir>/rpmbuild/RPMS/*/*': No such file or directory This change is the exact equivalent of bc4bbc42899a (which applied to Fedora).

narrow: don't compress the bundle2 when sending 'error:abort' This is similar to waht getbundle() does and also explicitly specifies that we should get a compressed bundle2 in normal cases when not sending 'error:abort'. Differential Revision: https://phab.mercurial-scm.org/D4934

push: add "remote" to 'repository changed while pushing' messages (issue5971) Differential Revision: https://phab.mercurial-scm.org/D4933

fuzz: try setting PYTHONNOUSERSITE=1 to avoid loading site-packages Right now the fuzzer is crashing trying to look up the home dir for uid 0, which is breaking in the fuzz environment. Differential Revision: https://phab.mercurial-scm.org/D4936

perf: extract result formatting in its own function This will make it easier to reuse in another changesets.

perf: extract the timing of a section in a context manager This makes it easier to reuse it in other (future) part of the code that requires their own time management.

pref: support negative indexing in perfrevlogrevisions This is useful to check for a consistent final slice in multiple different repositories.

perf: accept formatter option for perfmanifest

perf: fix -T json The previous code was mixing formatting and data, breaking `-T json` with unexpected data. We fix the issue and add a test to prevent future regression.

formatter: more details on assertion failure This is useful when the assertion fails.
