This commit annotates most of interpreterbase.py. However,
there are stil the @wraps missing, since I am unsure what
the types are supposed to be here.
This also fixes that the keys in ArgumentNode.kwargs are
all of the type BaseNode now. Before this commit, it was
possible that both strings and Nodes where used as keys.
the check for which files can be compiled are called again and again on
the same files over and over again. Caching this here shaves off 11s of
the build time of efl (which has grown in the last 3 versions to over 40
sec. again)
in order to deduplicate arguments as much as possible, we need to check
if a argument is already part of the list. Which is quite slow because
we are checking 3 lists for that.
In smaller projects this might be not of interested. However, in efl
things are quite "heavy", alone generating the ninja file took 40 sec..
16 sec. are spent in __iadd__ of CompilerArgs.
What this patch does to speed this all up is:
1. We only check if a element is in post when we know that it must be in
post same for pre.
2. the checks for if we already do contain a specific value are now done
via a dict, and not via the list.
This overall brings the time from 16 sec. spent in __iadd__ to 9 sec. in
__iadd__.
Another possible solution for all this is to have a internal structure
of CompileArgs of trees, so you have the "basic" layer of arguments
where the position does not matter. Additionally, you have two stacks of
lists, the pre stack and the post stack, duplicates can then be checked
when itereting, which would safe another ~4s in terms of efl. However, i
do not have time for this undertaking right now.
Currently, detect_machine_info() is called:
- from Environment.__init__(), before we have any compiler available
- from Interpreter.__init__() with the list of languages provided to
project() (determined via the initial parse_project())
This is not sufficent in the case where no languages are specified to
project() and are later added with add_languages().
We cannot correctly detect that the host machine should be treated as
x86 (on x86_64 hardware) until we have a compiler we are told to use.
Redetect machines after project(), and after every add_languages().
Running the build step of test '127 custom target directory install'
again, using the VS backend, causes 'docgen.py' to try to create the
target directory again (which fails with a FileNotFound exception).
I'm guessing that perhaps this is a shortcoming of the VS backend that
it doesn't correctly give this target a dependency on the directory.
I'm not sure that this test is actually valid meson: the reference
manual says custom_target(output:) should be a list of files, and not a
directory, as is this case here.
Add coverage of a simple 'configure then build' sequence, to catch bugs
which occur with that.
Also, to simplify returning results from functions called by
_run_test(), allow it also throw TestResult objects, which run_test()
catches and returns.
Test that the host_machine is correctly detected after add_languages(),
when no langauge is initially specified in project().
In the MSYS2 MSYSTEM=MINGW32 environment (64-bit MSYS2 but with a
i686-w64-mingw32 targeted gcc as gcc) this test fails, as it
(incorrectly) tries to build retval-x86_64.S using an x86 compiler.
There were two things mypy was warning about:
1) it doesn't understand hasattr()
2) It was possible for mlog.{error,warning,deprecation} to get passed
multiple values for the once keyword argument.
Mips architectures may have `el` on the end, to differentiate the little
endian from the big endian variants. We don't encode endianness in the
cpu names, so ensure we've stripped that.

Warnings have a location node object (with subdir and lineno
attributes), which is passed as a location: kwarg to mlog.warning() and
formatted in _log_error().
Re-purpose the subdir attribute (path relative to the source root dir,
with an implied filename of 'meson.build'), which is stored into the
node by parser(), to contain a pathname.
(Properly I should rename 'subdir' -> 'file' everywhere, but that's a
lot of churn just to see if this works)
Notes:
The warning location node may also have a colno attribute, which is
currently ignored by _log_error().
We can't currently issue warnings with locations in meson_options.txt
because the filename isn't part of the location (as it's assumed to be
'meson.build).
A MesonException has file, lineno and colno attributes, which get
formatted as a location in mlog.exception().
The file attribute got changed from a path relative to the root source
directory to a pathname (absolute or relative to cwd) in one place in
commit b8fbbf59. Adjust all the other places the file attribute is set
to match.
Also:
Setting MesonException.file seems to be missing in the case where Parser
returned a non-CodeBlockNode object. Fortunately, that looks like it's
unreachable, but add it just in case.
This test was never testing what it claimed to test, simply failing with
"ERROR: No C-like compilers are available, cannot find the framework"
because a C-like language is missing from project().
These are always failing just because the exact version constraint isn't
satisfied, e.g. "ERROR: Meson version is 0.53.999 but project requires
0.48.0"
This test was never testing what it claimed to test, simply failing with
'ERROR: First statement must be a call to project' because it's missing
project().
Since #5279, all unrecognized escape sequences are literal, so I don't
think there's anything to test here.
Emscripten does have a stand alone linker, wasm-ld. This patch adds the
linker, adds detection for the linker, and removes the IsLinkerMixin for
emscripten. This is a little more correct, and makes the code a lot
cleaner and more robust.
Emscripten has pthread support (as well as C++ threads), but we don't
currently implement them. This fixes that by adding the necessary code.
The one thing I'm not sure about is setting the pool size. The docs
suggest that you really want to do this to ensure that your code works
correctly, but the number should really be configurable, not sure how to
set that.
