Also prevent from using a parent directory as builddir by mistake.

- MesonException for errors is clearer than SystemExit('error message')
and provides meson-formatted "ERROR: ..."
- `raise SystemExit` with no parameter isn't obvious that it intends to
exit successfully
While clarifying the latter, it was observed to cause
test_preprocessor_checks_CPPFLAGS() failure to be ignored. That test
checks get_define() on both c and cpp compilers, which means we need to
define either CPPFLAGS or both CFLAGS+CXXFLAGS.
We need to remember its value when reconfiguring, but the Build object
is not reused, only coredata is.
This also makes CLI more consistent by allowing `-Dvsenv=true` syntax.
Fixes: #11309
This allows to run setup command regardless whether the builddir has
been configured or not previously. This is useful for example with
scripts that always repeat all options.
meson setup builddir --reconfigure -Dfoo=bar
This can happen from typos, which then confusingly claim that neither
build directory has a meson.build file because the implicit . directory
was not actually one of the directories. Instead a random command line
argument was interpreted as a directory name.
Fixes#11472
mypy is pretty dumb when it comes to unions of callables (pylance is
also dumb in this regard), and can't figure out that our use of
`mlog.debug | mlog.log` is perfectly safe. We also can't annotate them
properly to cast them to a valid subset of arguments because you can't
have splats in `typing.Callable`, so I've done enough to make it work.
The one case of this was a false-positive, but what we were doing
(checking locals()) is not idiomatic. I've replaced the call to
`locals()` with the obvious `var: T.Optional[str] = None` with check
instead.
We want to optimize out some internal codepaths used at build time by
avoiding work such as argparse. This doesn't work particularly well when
the argparse arguments are imported before then. Between them, they
indirectly import pretty much all code anywhere, and msetup alone
imports most of it.
Also make sure the regenerate internal script goes directly to msetup.
It's broken in various circumstances, no one seems to actually use it,
CI doesn't test it, no one is committed to maintaining it, etc. etc.
etc.
Also, projects doing trivially reasonable things, such as generating
"foo/util.py" and "bar/util.py", create clashing output names. This will
never, ever, ever, ever work with layout=flat.

Until we invoke interpreter.Interpreter(b, ...) the coredata options
still have their default values and thus cannot be used sensibly.
Currently the warning never shows (other than, unsurprising in
retrospect, during --internal regenerate).
It is a commonly needed information to help debugging build issues. We
already were printing options with non-default value at the end of the
configure but outside of the summary.
Keeping the list of user defined options in the interpreter will also in
the future be useful to use new default value on reconfigure.
This fix issue when using --wipe and the machine file was passed as a
pipe and written locally, or when the file was resolved in XDG_DATA_HOME
or XDG_DATA_DIRS.
Fixes: #8560
This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
I would have prefered to do these seperatately, but they are combined in
some cases, so it was much easier to convert them together.
this eliminates the builtins_per_machine dict, as it's duplicated with
the OptionKey's machine parameter.
I wrote this to convert run_tests.get_backend_commands() over to the
new meson wrappers, but that turned out to be harder than I expected,
so just splitting this out for now.
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
When wiping a build tree with --wipe, every entry in the build directory
is removed with mesonlib.windows_proof_rmtree() for directories and
mesonlib.windows_proof_rm() for other files. Symlinks to directories are
considered directories, resulting in the former being called. This
causes an exception to be raised, as the implementation calls
shutil.rmtree(), which isn't allowed on symlinks.
Fix this by using mesonlib.windows_proof_rm() for symlinks.

Build and target info is confusing in that case. However still log that
information, as it is useful in case something slips out of sync and
needs to be debugged.
* coredata: Correctly handle receiving a pipe for native/cross files
In some cases a cross/native file may be a pipe, such as when using bash
process replacement `meson --native-file
<([binaries]llvm-config='/opt/bin/llvm-config')`, for example. In this
case we copy the contents of the pipe into a file in the meson-private
directory so we can create a proper ninja dependency, and be able to
reload the file on --wipe/--reconfigure. This requires some extra
negotiation to preserve these native/cross files.
Fixes#5505
* run_unitests: Add a unit test for native files that are pipes
Using mkfifo.
This creates a new command line option to store pkg_config_path into,
and store the environment variable into that option. Currently this
works like the environment variable, for both cross and native targets.
