Several bits of output were missing[1], unless the DETACHED_PROCESS flag is
_not_ passed to subprocess.Popen(). The problem with that is it briefly opens
and closes several cmd.exe windows on screen. Foozy also mentioned some other
issues in that thread.
With this, the last of the long standing Windows failures fixed, the test suite
now runs cleanly (536 ran, 67 skipped) on Windows 7 x64, with python 2.7.13. \o/

I'm not sure if this is better. If we're planning to add a template keyword
that returns obsoleted nodes unavailable in the repo (i.e. they have no valid
revision numbers), we might want to use the current "node"-only format
everywhere.
I tripped on some weirdness relating to _thread vs threading way down
in a dep of highlight recently. I'm not really sure why I'm only just
seeing this defect now, but experimentally this fixes the problem, and
shouldn't cause any load-time slowness for people until pygments is
actually about to be used since highlight.highlight is still lazily
loaded in the highlight/__init__.py file.
When hghave testing goes awry, the output order was changing on Windows.

Since 'skipped: unknown feature: notarealhghavefeature\n\n' is printed to stdout
and the rest to stderr, it seems like maybe stdio isn't line buffered on
Windows. When a program exits, stdout is flushed before stderr[1].

On Windows, output streams are buffered when redirected to a file, and
TerminateProcess() apparently doesn't trigger a flush. This left
test-http-proxy.t missing part of the last line when it cat'd proxy.log[1].
Flushing stderr is all that is needed (on py27 anyway). I originally flushed
stdout too, but that added additional output to the log:

context.py seems not a good place to host these functions.

This module hosts the following functions. They are somewhat similar (e.g.
scanning revisions using heap queue or stack) and seem non-trivial in
algorithmic point of view.
- _revancestors()
- _revdescendants()
- reachableroots()
- _toposort()
I was thinking of adding revset._fileancestors() generator for better follow()
implementation, but it would be called from context.py as well. So I decided
to create new module.
Naming is hard. I couldn't come up with any better module name, so it's called
"dag operation" now. I rejected the following candidates:
- ancestor.py - existing, revlog-level DAG algorithm
- ancestorset.py - doesn't always return a set
- dagalgorithm.py - hard to type
- dagutil.py - existing
- revancestor.py - I want to add fileancestors()

Even on CentOS 7, git is at version 1.8. It seems git 1.9 is when
ext::sh was introduced so we a check for that. The way these functions
are written follows the same style and format for the way we check svn
and bzr versions.
We move the feature to a proper configuration and document it. The config goes
in the 'server' section because it feels like something the server owner would
want to decide. We pick and open field because it seems likely that other
checking levels will emerge in the future. (eg: server like the mozilla-try
server will likely wants a "none" value)
The option name contains 'push' since this affects 'push' only. The option value
'check-related' is preferred over one explicitly containing 'allow' or 'deny'
because the client still have a strong decision power here. Here, the server is
just advising the client on the check mode to use.
After dropping the garbage collector hack, `hg perfstartup` started yelling
about not being able to import the evolve extension, which I have in my user
config. Launching `env` shows that an empty HGRCPATH isn't exported to the
environment. Since `env` doesn't quote, I have no idea if the variable is
trimmed, but Mercurial doesn't complain when processing it.
Add a 'predecessors' template that returns the list of all closest known
predecessors for a changectx. The elements of the list are row changectx node id
formatted by default as short nodes.
The "closest predecessors" are the first locally known revisions encountered
while, walking predecessors markers. For example:
1) If a (A, (B)) markers exists and both A and B are locally known A is a
closest predecessors of B.
2) If a (A, (B)) and (B, (C)) markers exists and only A and C are known
locally, A will be the closest precursors of C.
This logic respect repository filtering. So hidden revision will be skipped by
this logic unless --hidden is specified. Since we only display the visible
predecessors, this template will not display anything in most case. It makes a
good candidate for inclusion in the default log output.
I added a new test-file for testing the precursors in various scenarios. This
test file will also be used for the successors template.
A new "obsutil" module has been added to start gathering utility function
outside of the large obsolete.py module.
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.
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.
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.
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.
