killdaemons: explicitly set the ctypes signatures When I tried importing util.posixfile to work around removing a file opened by another process on Windows, it brought along the declarations in win32.py, which broke the error handling[1]. It doesn't seem worth hacking killdaemons[2] just to isolate these declarations in win32.py, so just declare them here to prevent any future issues. (win32.py mentions the declarations are required by pypy.)

hghave: enable 'serve' on Windows I've been using a local hghaveaddon.py to enable this for a couple of months with reasonable success, and 'killdaemons' is already enabled on Windows. There's one failure[1] in test-http-proxy.t that this adds, which I can't figure out. [1] https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-April/096987.html

contrib: add a ratchet for tests in Python 3 This gives us an easy way to automatically update passing tests in Python 3.

contrib: check in a whitelist of passing tests in Python 3

tests: try and fail more gracefully with broken unicode escapes

md5sum: adapt for python 3 support

profiling: allow configuring minimum display threshold for hotpath statprof.display_hotpath() accepts a "limit" function to choose the minimum threshold for samples to display. The default is 0.05, which means you don't need individual items contributing less than 5%. I had a need to adjust this threshold. We already have a config option for it. So let's reuse it. check-config.py doesn't like having multiple defaults for the ui.configwith() calls. The behavior is obviously correct. I'm not sure if it is worth teaching check-config.py how to ignore this. So I've just accepted the new output.

config: document profiling.show{min,max}
