When projects do not specify a minimum meson version, we used to avoid
giving them the benefit of the Feature checks framework. Instead:
- warn for features that were added after the most recent semver bump,
since they aren't portable to the range of versions people might use
these days
- warn for features that were deprecated before the upcoming semver
bump, i.e. all deprecated features, since they aren't portable to
upcoming semver-compatible versions people might be imminently upgrading
to
Previously, setting `MESON_TESTTHREADS` to a number lower than 1
resulted in unexpected behavior. This commit introduces test for
negative value (with fallback to 1), and fallback to core count in case
it is set to 0.
It improves experience in job-matrix type of CI workflows, where some
jobs within the matrix require single job execution, whereas others can
default to taking core count as the job count.

Although it's not especially common, there are certainly cases where it's
useful to pass the path to an external program to a test program.

We've documented these lists as being `List[Path]`, but then we have the
potential to insert a None into them via the `rel_path()` function,
which can return `None` in some cases. Currently we fix some (but not
all) of these later, but we should actually remove them from the list
before we assign, so that it's actually a `List[Path]` at all times.
While we're here I've simplified the logic a bit.
Closes: #13551
It was possible (with some frequency) for the clang-tidy/format target
to continue starting new subprocesses after a CTRL-C, because we were
not canceling the already queued tasks and waiting for all of them.
This makes a best-effort attempt to cancel all further subprocesses. It
is not 100%, because there is a race that is hard to avoid (without
major restructuring, at least): new subprocesses may be started after
KeyboardInterrupt (or any other exception) is raised but before we get
to the cancellation.
When the race happens, the calling ninja may exit before Meson exits,
causing some output (from clang-tidy/format and Meson's traceback) to be
printed after returning to the shell prompt. But this is an improvement
over potentially launching all the remaining tasks after having returned
to the shell, which is what used to happen rather often.
In practice, it appears that we cleanly exit with a pretty high
probability unless CTRL-C is hit very early after starting (presumably
before the thread pool has launched subprocesses on all its threads).
The following is valid meson:
```meson
a = '''This string can't be simplified'''
```
which cannot be simplified because of the `'` in it, as
```meson
a = 'This string can't be simplified'
```
Is invalid.
Potentially we could convert that with escapes, but it seems reasonable
to me to leave this, since it may be desirable to not have lots of
escapes in a string. `'''I can't believe it's her's!'''` is much more
readable than `'I can\'t believe it\'s her\'s!'`, for example.

- Fix indentation of comments in arrays
- Fix indentation of comments in dicts
- Fix indentation of comments in if clauses
- Fix indentation of comments in foreach clauses
Which happens when a .editorconfig is in a subdirectory, not the root.
In this case we need Set the fallback value to `False`, which is what
editorconfig expects.
Closes: #13568
The pkgconfig file in Debian and Ubuntu is definitely broken and we've
reported it upstream, but we don't really want to keep our image building
failing while we wait for that to be fixed.
Skip the auto/pkgconfig test if both: a) we're on Ubuntu, and b) the .pc
checksum matches a known-bad copy. I'm also CC'd to the bug to catch if it
gets fixed.
Bug: https://bugs.debian.org/1078026
for test attributes that are class constant. This reduces the work that
must be done for each test case, allowing some of the setup work to be
done once for the entire class.
Meson accidentally strips '-isystem' from C build args like ['-isystem',
'/path/to/headers'] if the compiler includes the current working directory
in the header search paths. The root cause is that '-isystem'[8:] evaluates
to an empty string and os.path.realpath('') returns the absolute path to
the current working directory, causing meson to think that '-isystem'
specifies a default include path.
Different compiler versions varies whether the current working directory is
in its search paths. For example, on Ubuntu 21.04:
# gcc -xc -v -E -
gcc version 10.3.0 (Ubuntu 10.3.0-1ubuntu1)
#include "..." search starts here:
#include <...> search starts here:
.
/usr/lib/gcc/x86_64-linux-gnu/10/include
/usr/local/include
/usr/include/x86_64-linux-gnu
/usr/include
End of search list.
While on Ubuntu 24.04:
# gcc -xc -v -E -
gcc version 13.2.0 (Ubuntu 13.2.0-23ubuntu4)
...
#include "..." search starts here:
#include <...> search starts here:
/usr/lib/gcc/x86_64-linux-gnu/13/include
/usr/local/include
/usr/include/x86_64-linux-gnu
/usr/include
End of search list.
Do not check the '-isystem=' and '-isystem/path/to/header' cases when the
option is '-isystem' but the path that follows is not a default search
path.

This fixes a pesky failure in vs2019 vc2019x64ninja for d/11 dub:
```
Searching in DUB cache for compatible urld.lib
WARNING: No such cache folder: C:\Users\VssAdministrator\AppData\Local\dub\packages\urld-2.1.1\urld\.dub\build
ERROR: urld@2.1.1 not found
You may try the following command to install the necessary DUB libraries:
dub run --yes dub-build-deep -- urld --arch=x86_64 --compiler=dmd --build=debug
Run-time dependency urld found: NO
test cases\d\11 dub\meson.build:13:11: ERROR: Dependency "urld" not found
```
Follow dub's advice by installing urld in ci/run.ps1 before the testsuite;
we were already doing this for ubuntu, opensuse, and even recommending
it in our docs before now:
* ci/ciimage/ubuntu-rolling/install.sh
* ci/ciimage/opensuse/install.sh
* docs/markdown/Dependencies.md
We also bump to 'ci4' which has newer D added (from the cidata repo).
- check version of DUB for compatibility with Meson
- use "cacheArtifactPath" to locate DUB libraries in the cache
- propose `dub build --deep` command to Meson users for missing DUB
packages
Depending on DUB version, it will look either in the old cache structure
or use this new `dub describe` entry.

Test '230 external project' uses make, but is too dumb to use the
platform conventions for shared library names in installed files
expected by shared_lib, so special case that.
