Rewrite the SingleTestRunner to use asyncio to manage subprocesses,
while still using subprocess.Popen to run them. Concurrency is
managed with an asyncio Semaphore; for simplicity (since this is
a temporary state) we create a new thread for each test that is run
instead of having a pool.
This already provides the main advantage of asyncio, which is better
control on cancellation; with the current code, KeyboardInterrupt
was never handled by the thread executor so the code that tried to handle
it in SingleTestRunner only worked for non-parallel tests. And
because executor futures cannot be cancelled, there was no way for
the user to kill a test that got stuck. Instead, without executors
^C exits "meson test" immediately. The next patch will improve things
even further, allowing a single test to be interrupted with ^C.
Distinguish a failure due to user interrupt from a presumable ERROR
result due to the SIGTERM. The test should fail after CTRL+C even if
the test traps SIGTERM and exits with a return code of 0.
ProcessLookupError can also happen from p.kill(). There is also
nothing we can do in that case, so move the "try" for that
exception to the entire kill_process function.
The ValueError case seems like dead code, so get rid of it.
A large part of _run_cmd is devoted to setting up and killing the
test subprocess. Move that to a separate function to make the
test runner logic easier to understand.
Use asyncio futures for the run loop, while still handling I/O in
a thread pool using run_on_executor.
The handling of the test result is not duplicated anymore between
run_tests and drain_futures. Instead, the test result is always processed
and printed by run_test after single_test.run() completes and (in verbose
mode) it cannot interleave with the test output. Therefore the special
case for self.options.num_processes == 1 can be removed.
run_special and doit are the same except that run_special forgot to
set self.is_run. There is no need for the duplication.

You could always specify a list of tests to run by passing the names as
arguments to `meson test`. If there were multiple tests with that name (in the
same project or different subprojects), all of them would be run. Now you can:
1. Run all tests with the specified name from a specific subproject: `meson test subprojname:testname`
1. Run all tests defined in a specific subproject: `meson test subprojectname:`
Also forbid ':' in test names. We already forbid this elsewhere, so
should not be a big deal.
This allows the NINJA environment variable to support all the Windows special
cases, especially allowing an absolute path without extension.
Based on a patch by Yonggang Luo.

This removes the check for "mingw" for platform.system(). The only case I know
where "mingw" is return is if using a msys Python under a msys2 mingw environment.
This combination is not really supported by meson and will result in weird errors,
so remove the check.
The second change is checking sys.platform for cygwin instead of platform.system().
The former is document to return "cygwin", while the latter is not and just
returns uname().
While under Cygwin it uname() always starts with "cygwin" it's not hardcoded in MSYS2
and starts with the environment name. Using sys.platform is safer here.

According to the specification:
https://testanything.org/tap-specification.html#skipping-tests
The harness should report the text after # SKIP\S*\s+ as a reason for
skipping.
(it's not exactly like the TODO directive, the phrasing/presentation of
the spec could be improved).
* mtest: TestResult.SKIP is not a failure
If some but not all tests in a run were skipped, then the overall result
is given by whether there were any failures among the non-skipped tests.

* Add test-cases for partially skipped TAP tests
issue7515.txt is the output of one of the real TAP tests in gjs, which
failed as a result of #7515. The version inline in meson.build is
a minimal reproducer.

D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
Gtest can output junit results with a command line switch. We can parse
this to get more detailed results than the returncode, and put those in
our own Junit output. We basically just throw away the top level
'testsuites' object, then fixup the names of the tests, and shove that
into our junit.
JUnit is pretty ubiquitous, lots of services and results viewers
understand it, in particular gitlab and jenkins know how to consume
JUnit xml. This means projects using CI services can have their test
results consumed automatically.
Fixes: #6972
Remove some weirdness from test output such as extra commas, missing
spaces and way too precise time durations. Also improve the overall
alignment of the output.
According to http://testanything.org/tap-specification.html
"Any output line that is not a version, a plan, a test line, a
diagnostic or a bail out is considered an “unknown” line. A TAP parser
is required to not consider an unknown line as an error but may
optionally choose to capture said line and hand it to the test
harness, which may have custom behavior attached [...] TAP::Harness
reports TAP syntax errors at the end of a test run".
(glib gtest can generate empty lines)
The size of WINEPATH is limited (1024 [until recently]), we
can very easily reach that limit, and even the new one (2048) so
try to keep path as small as possible by using the shortPath
version of paths.
Also assert that we do not reach the new hard limit.
And avoid having duplicates in the list of path.

This started out with a bug report of mtest trying to add bytes + str,
which I though "Oh, mypy can help!" and turned into an entire day of
awful code traversal and trying to figure out why attributes were
changing type. Hopefully this makes everything cleaner and easier to
follow.
