Meson is not warning if you join paths with / but you are requesting a
version older than 0.49.0; fix this before adding more features to the
division operator.

These don't work and no one has fixed them. When I've tried to
download dmd for windows I can't get a valid installer from their
website. Let's at least turn the CI green.
This doesn't touch everything as it's just based on the python3 module
tests, ported to the python module. It's still better than the one very
basic test in the unit test module.
Deal with clang-cl doing the sane (but different to MSVC) thing, of
generating an empty import library, rather than silently ignoring
/IMPLIB when there are no exports.
Extend platform_fix_name() to handle this case
We avoid using library(version:), so we don't have to teach
platform_fix_name() all the platform details of versioned shared library
naming. Hopefully that's exercised by platform-specific tests...
Use the compiler detector in detect_system_compiler(), rather than trying to
guess based on what it is the PATH (which could utterly fail e.g when CC env
var is set)
Note that this detection is only used by platform_fix_name() to interpret
installed_files.txt
This has the adventage that "meson --help" shows a list of all commands,
making them discoverable. This also reduce the manual parsing of
arguments to the strict minimum needed for backward compatibility.
As per commit 2340fd3, unexpected installed files are not reported anymore when
using compilers other than 'cl', this regression was introduced in the attempt
of not reporting extra .pdb files, but actually caused any non extra .pdb file
in other compilers to be ignored.
Fix boolean test, by reporting any extra file a part '.pdb' ones under non 'cl'
compiler, while anyone under 'cl'.
This is a simple test case, checking for installed_files.txt, which just
makes sure the syntax is accepted.
Manual tests confirmed the permissions were set correctly.
A follow up commit adds a unit test based on this directory.
Instead of using fragile guessing to figure out how to invoke meson,
set the value when meson is run. Also rework how we pass of
meson_script_launcher to regenchecker.py -- it wasn't even being used
With this change, we only need to guess the meson path when running
the tests, and in that case:
1. If MESON_EXE is set in the env, we know how to run meson
for project tests.
2. MESON_EXE is not set, which means we run the configure in-process
for project tests and need to guess what meson to run, so either
- meson.py is found next to run_tests.py, or
- meson, meson.py, or meson.exe is in PATH
Otherwise, you can invoke meson in the following ways:
1. meson is installed, and mesonbuild is available in PYTHONPATH:
- meson, meson.py, meson.exe from PATH
- python3 -m mesonbuild.mesonmain
- python3 /path/to/meson.py
- meson is a shell wrapper to meson.real
2. meson is not installed, and is run from git:
- Absolute path to meson.py
- Relative path to meson.py
- Symlink to meson.py
All these are tested in test_meson_commands.py, except meson.exe since
that involves building the meson msi and installing it.
There are cases when it is useful to wrap the main meson executable with
a script that sets up environment variables, passes --cross-file, etc.
For example, in a Yocto SDK, we need to point to the right meson.cross
so that everything "just works", and we need to alter CC, CXX, etc. In
such cases, it can happen that the "meson" found in the path is actually
a wrapper script that invokes the real meson, which may be in another
location (e.g. "meson.real" or similar).
Currently, in such a situation, meson gets confused because it tries to
invoke itself using the "meson" executable (which points to the wrapper
script) instead of the actual meson (which may be called "meson.real" or
similar). In fact, the wrapper script is not necessarily even Python, so
the whole thing fails.
Fix this by using Python imports to directly find mesonmain.py instead
of trying to detect it heuristically. In addition to fixing the wrapper
issue, this should make the detection logic much more robust.
