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.
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.
* unittests: fix finding python2 if the binary is named python2
Because of the way the python module works the simplicity of the test
function is no longer valid, we need to have and additional name
parameter to make the python module work, as it doesn't look for an
entry called "python2" or "python3", only "python"
* unittests: Don't make our python 2.x check debian specific
* unittests: On macOS the python2 binary is still called python
This adds a warnings counter for subprojects that passed. This is to
encourage developpers to check warnings in the logs and hopefully fix
them. Otherwise they could be hidden in hundreds lines of logs.
This also print the error message for subprojects that did not pass. The
error message is often enough to fix the issue (e.g. missing
dependency) and it's easier than searching in the logs why a subproject
failed.
Currently, giscanner and the gicompiler paths are only scanned via pkg-config
if they are first found in the host path.
Add a else statement to fix this oversite.
Currently, meson hard codes the paths of these binaries which results in
cross-compiled environments to run the host versions of these tools.
However, GObject-introspection provides the appropriate paths to these
utilities via pkg-config
find_program is needed in the case g-i is built as a subproject. If
g-ir-scanner or g-ir-compiler are in the build or source directory use those.
If they aren't found in the source directory, use the results from pkg-config.
