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

branch: allow changing branch of merge commits with --rev Tests show that changing branch of merge commits works fine with evolution and without, so let's allow it. Other safeguards should prevent users from shooting themselves in the foot.

lfs: ensure that the return of urlopener.open() is closed No problem observed, just an oversight noticed while reading documentation.

http: allow 'auth.prefix' to have a username consistent with the URI It may be a little weird to put a username in the prefix, but the documentation doesn't disallow it, and silently disallowing it has caused confusion[1]. The username must match what is passed in (which seems to be from the URI via a circuitous route), as well as 'auth.username' if it was specified. I thought about printing a warning for a mismatch, but we already don't print a warning if the 'auth.username' and URI username don't match. This change allows the first and second last new test cases to work as expected. It looks like this would have been a problem since at least 0593e8f81c71.
