perf: add a `setup` argument to run code outside of the timed section With this new argument, it is possible to perform special setup and cleanup outside of code actually timed. This is useful to provide more accurate benchmark.

perf: explicitly pass title as a keyword argument in `perfdiffwd` This will help to update the timer function arguments in a later changeset.

ui: unify argument name of ui.log() It's called an "event" in both blackbox and logtoprocess.

logtoprocess: extract logger class from ui wrapper It provides the same interface as the blackboxlogger. The ui wrapper will be removed shortly.

py3: use node.hex(m.digest()) instead of m.hexdigest() hashlib.sha1.hexdigest() returns str on Python 3. Differential Revision: https://phab.mercurial-scm.org/D5287

tests: stabilize the recent checkexec changes on Windows This goes with bd0874977a5e.

tests: add Balto configuration file I have been developing a Mercurial test runner plugin for being able to run Mercurial tests with Balto (https://bitbucket.org/lothiraldan/balto/src/default/). Balto requires a configuration file so let's include it, I have added the required information in the configuration file as comments. I hope Balto would be an helpful tool for other people than me.

tests: make test-alias.t pass with re2 Locally, these "non-ASCII character in alias" errors don't show up, though I get them when the alias is defined at the command line rather than in an hgrc. The brokenness comes from the fact that hgrcs are parsed with regexes, and re/re2 differ in this way: $ python -c 'import re; print(re.compile("(.*)").match("aaa\xc0bbbb").groups())' ('aaa\xc0bbbb',) $ python -c 'import re2; print(re2.compile("(.*)").match("aaa\xc0bbbb").groups())' ('aaa',) Apparently re2 stops when it encounters invalid utf8 (which I suppose makes sense given that '.' matches what appears to be a codepoint rather than a byte). This is presumably a bug in hg, but not very important, so just change the test to stick to valid utf8. Differential Revision: https://phab.mercurial-scm.org/D5288

context: remove seemingly impossible code branch I'm not a Python expert, but I can't think of a way that the following branch can ever be hit: def _changeid(self): if r'_changeid' in self.__dict__: return self._changeid It seems to me that if that condition is true, then this function would not have been called. The only exception I can think of is if a reference to the function had been stored beforehand, something like this: c = fctx.__dict__['_changeid'] fctx._changeid c() But that seems like very unlikely code to exist. The condition was added in 921b64e1f7b9 (filecontext: use 'is not None' to check for filelog existence, 2013-05-01) as a "bonus" change (in addition to what the patch was actually about) Differential Revision: https://phab.mercurial-scm.org/D5289
