commit: select template by spec.ref name And load all templates defined in [committemplate] since the selected template is no longer be named as 'changeset'.

commit: do not look up committemplate in template paths (BC) From 5375ba75df40 and de5cee8ba088, I don't think the current behavior is intended. Commit templates should be processed as literal templates.

formatter: always store a literal template unnamed Now spec.ref should be '' if spec.tmpl is specified. Since spec.ref is the option to select the initial template to be rendered, it doesn't make sense to store the given literal template as spec.ref.

formatter: load templates section like a map file Since a map file has another level to select a template (spec -> mapfile -> topic), this isn't exactly the same as how a map file works. But I believe most users would expect the new behavior. A literal template is stored as an unnamed template so that it will never conflict with the templates defined in [templates] section.

test-command-template: rewrite recursion tests by using a map file A literal template will be unnamed soon, so no recursion will be practically made by using -T option.

templater: add simple interface for unnamed template (API) This provides a simpler API for callers which don't need full templating stack. Instead of storing the given template as the name specified by topic, use '' as the default template to be rendered.

ui: add support for a tweakdefaults knob We've been talking for years about a one-stop config knob to opt in to better behavior. There have been a lot of ideas thrown around, but they all seem to be too complicated to get anyone to actually do the work.. As such, this patch is the stupidest thing that can possibly work in the name of getting a good feature to users. Right now it's just three config settings that I think are generally uncontroversial, but I expect to add more soon. That will likely include adding new config knobs for the express purpose of adding them to tweakdefaults.

localrepo: remove unused addchangegroup() (API) This completes the cleanup started in d3775db748a0 (localrepo: move the addchangegroup method in changegroup module, 2014-04-01).

changegroup: rename "dh" to the clearer "deltaheads" We have a lot of frequently used abbreviations, but this is not one of them.

changegroup: rename "srccontent" to "cgnodes" It's the list of nodes in the incoming changegroup, so "cgnodes" made more sense to me.

revlog: rename list of nodes from "content" to "nodes" It seems like the reason for "content" is that the variable contains the nodes that the changegroup "contains", see e234eda20984 (revlog: make addgroup returns a list of node contained in the added source, 2012-01-13), but "nodes" seems much clearer.

revlog: delete obsolete comment The comment seems to refer to code that was deleted in 557988c691d1 (revlog.addgroup(): always use _addrevision() to add new revlog entries, 2010-10-08).

revlog: delete dead assignment in addgroup()

pycompat: move the queue related definitions below queue import This helps in understanding why empty and queue are there.

pycompat: move multiline comments above a function to function doc pycompat.py is unorganized and looks ugly. Next few patches will try to make it look more cleaner so that adding more code is easy and reading code also. This patch moves the multiline comments above functions to function docs. While moving, I improved the comments and make them better suitable for func doc. While I was here I drop a unrequired and misplaced comment.

py3: replace dict.iterkeys() with iter(dict) dict.iterkeys() does not exists on Python 3.

py3: explicitly convert dict.values() to a list on py3 dict.values() returns a dict_values() object, so we need to pass it into list() explicitly to get one.

py3: alias long to int and xrange to range in test-ancestor.py on Python 3

py3: add a new bytesurl() to convert a str url into bytes

py3: add a new strurl() which will convert a bytes url to str

killdaemons: fix WaitForSingleObject() error handling logic on Windows The error return is not 0 for this method, so _check() was doing nothing when an error occurred. This forces the error path, much like the check for OpenProcess(). The only unhandled return is now WAIT_ABANDONED, but I don't see how that could happen in this case.

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.
