Rust has it's own built in unit test format, which is invoked by
compiling a rust executable with the `--test` flag to rustc. The tests
are then run by simply invoking that binary. They output a custom test
format, which this patch adds parsing support for. This means that we
can report each subtest in the junit we generate correctly, which should
be helpful for orchestration systems like gitlab and jenkins which can
parse junit XML.
for non tap tests we want to associate names with the tests, to that end
store them as a dict. For TAP tests, we'll store the "name" as an
integer string that coresponds to the order that the tests were run in.
Flush after each output line, even if printing to a file, so that each
result is immediately visible down a pipeline.

The TestLogger class lets us move the code for all those log files
out of TestHarness. The interface is based on JunitBuilder, which
is converted already in this commit. Over the next commits, we
will also convert JSON, text and console output.
The main difference with JunitBuilder is that the completion method is
asynchronous. This can be useful if the logger needs to clean up after
itself and wait for asyncio tasks.

Just reuse the collected_failures collection now that it contains
TestRun objects. Move the code to generate the short form of the log
to TestRun.
Note that the first line of the error log is not included in
get_log()'s return value, so the magic "first four lines are passed
unscathed" is changed to three lines only. The resulting output is
like this:
--- command ---
<command line>
--- Listing only the last 100 lines from a long log. ---
--- stdout ---

If there's an UnicodeEncodeError while printing the error logs,
TestHarness tries an encode/decode pair to get rid of anything that
is not a 7-bit ASCII character; this however results in "?" characters
that are not very clear. To make it easier to understand what is
going on, use backslashreplace instead.
While at it, fix the decode to use a matching encoding. This will
only matter in the rare case of sys.stdout.encoding not being an
ASCII superset, but that should not matter.

Instead of colorizing the whole status line, only colorize the word
representing the outcome of the test (SKIP, OK, FAIL, etc.). This
is less intrusive, so the patch also does the following changes:
- colorize OK and EXPECTEDFAIL, respectively as green and yellow
- colorize the summary of failures as well.

Instead of storing the string, store the whole TestRun. In the
next patches we'll use this to colorize the summary of failures,
and to allow a few more simplifications.
There is some code duplication between the console and logfile
code, but it won't matter as soon as console and logfile output
will be in two completely separate classes.

Avoid passing them around as parameters; this will be useful when logging
is moved out of TestHarness, because individual loggers will call back
into TestHarness to do common formatting chores.

Place in TestRun everything that is needed in order to

This will provide a way to pass more information from the TestHarness
local variables to the SingleTestRunner and use them outside the
run_test function. For example, the name could be used to report
progress while the tests are running.

It is a usual workflow to fix something and retest to see if it is fixed using a
particular test. When tests start to become numerous, it becomes time consuming
for "meson test" to relink all of them (and in fact rebuild the whole project)
where the user has already specified the tests they want to run, as well as
the tests' dependencies.
Teach meson to be smart and only build what is needed for the test (or suite)
that were specified.

Avoid calling self.collected_failures.append twice, and avoid
inflated indentation by adding a "plain" decorator to mlog.
Fixes: ba71fde18 ("mtest: collect failures regardless of colorized console", 2020-10-12)
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.

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.

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.
