With the next patch, "meson test" will be using the targets introspection
information. Provide helper functions to share bits of code between
mintro.py and mtest.py.
This fix a regression introduced in Meson 0.56.0 when using python 3.5.
Also mention in documentation that using a meson dict does not guarantee
ordering.
Fixes: #8074.
Previously the destdir was ignored completely when using elevated
privileges to install files as pkexec stripped the DESTDIR environment
variable.
As the destdir is not supposed to require any special privileges
anyways, just re-raise the error.
The ninja path is already logged as part of configure. Logging it
again every time when using meson compile is overly verbose and
doesn't add much value for the user.
Otherwise it's not possible to share git subprojects via worktrees
when creating a worktree of a git repository that uses meson
subprojects.
The downside is that the user needs to be careful while adding commits
to each tree's index.
Allow methods on the compiler object to receive internal dependencies,
as long as they only specify compiler/linker arguments or other
dependencies that satisfy the same requirements.
This is useful if you're using internal dependencies to add special
"-D" flags such as -DNCURSES_WIDECHAR, -D_XOPEN_SOURCE_EXTENDED or
-DGLIB_STATIC_COMPILATION.
Adds TemporaryDirectoryWinProof which calls windows_proof_rmtree() on
error.
Use instead of hacky error handling (which might shadow other OSError)
in Compiler.compile().
Some CMake packages fail to find at all if no version is specified.
This commit adds a cmake_version parameter to dependency() to allow you
to specify the requested version.
This value shouldn't be set in the loop, it's probably been making
things slow, but also creates the potential that if choices is an empty
list that value would be unbound. While that's exteremly unlikly to
happen in practice, it is showing up as a warning from pylance.
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)
It turns out my first attempt to fix this in 00d5ef3191 ("Fix
clang-tidy return value reporting (#7949)") is not sufficient: The
local variable returncode is never updated and stays at 0. This fixes
the returncode calculation.
Fixes: cce172432b ("Use run-clang-tidy when available.")

`volatile` was previously mistakenly used in GLib to indicate that a
variable was accessed atomically or otherwise multi-threaded. It’s not
meant for that, and up to date compilers (like gcc-11) will rightly warn
about it.
Drop the `volatile` qualifiers.

These do not go into the command line, and therefore do not matter
for the purpose of avoiding unnecessary rebuilds after meson is
rerun. However, they complicate the task of finding differences
between build lines across meson reruns.
So take the easy way out and sort everything after | and ||.
With this change, there is absolutely no change in QEMU's 40000-line
build.ninja file after meson is rerun.
The order of keys in dictionaries cannot be relied upon, because the hash
values are randomized by Python. Whenever we iterate on dictionaries and
meson.build generates a list during the iteration, the different iteration
orders may cause random changes in the command line and cause ninja to
rebuild a lot of files unnecessarily.
The order of elements in sets cannot be relied upon, because the hash
values are randomized by Python. Whenever sets are converted to lists
we need to keep their order stable, or random changes in the command line
cause ninja to rebuild a lot of files unnecessarily. To stabilize them,
use either sort or OrderedSet. Sorting is not always applicable, but it
can be faster because it's done in C and it can produce slightly nicer
output.
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.
