Adds a new debug() function that can be used in the meson.build to
log messages to the meson-log.txt that will not be printed to stdout
when configuring the project.
Previously subprojects inherited languages already added by main
project, or any previous subproject. This change to have a list of
compilers per interpreters, which means that if a subproject does not
add 'c' language it won't be able to compile .c files any more, even if
main project added the 'c' language.
This delays processing list of compilers until the interpreter adds the
BuildTarget into its list of targets. That way the interpreter can add
missing languages instead of duplicating that logic into BuildTarget for
the cython case.
In the even that all of the inputs are generated, and they're all
generated into the same folder, and there are no subfolders, we would
fail to correctly handle all of the files after the main file. Let's fix
that.t
Apparently Azure provides 64-bit python2 when we try to test 32-bit, and
that breaks everything on the 32-bit test runner.
I don't understand the environment setup, and that runner is
disappearing soon anyway. Hopefully this shuts up the known breakage.
Perhaps when this test case was originally created, project tests could
not use a matrix of options? This is certainly possible today, so don't
write special unittest handling for this instead.
This adds proper visibility into what gets run and what doesn't. Now we
know which python executables got tested and which got skipped.
This reverts commit 79c6075b56.

PYTHONPATH cannot be reliably determined. The standard use case for
installing python modules with Meson is mixed pure sources (at least
`__init__.py`) and compiled extension_modules or configured files.
Unfortunately that doesn't actually work because python will not load
the same package hierarchy from two different directories, one a source
directory and one a (mandatory) out of tree build directory.
(It kind of can, but you need to do what this test case accidentally
stumbled upon, which is namespace packages. Namespace packages are a
very specific use case and you are NOT SUPPOSED to use them outside that
use case, so people are not going to use them just to circumvent Meson
devenv stuff as that would have negative install-time effects.)
Adding PYTHONPATH anyway will just lead to documentation commitments
which we cannot actually uphold, and confusing issues at time of use
because some imports *will* work... and some will *not*. The end result
will be a half-created tree of modules which just doesn't work together
at all, but because it partially works, users attempting to debug it
will spend time wondering why parts of it do import.
For any case where the automatic devenv would work correctly, it will
also work correctly to use `meson.add_devenv()` a single time, which is
very easy to manually get correct and doesn't provide any significant
value to automate.
In the long run, an uninstalled python package environment will require
"editable installs" support.
Dependencies in the "if_true" keyword argument do not prevent the
sources from being used; in other words, they work just like dependencies
with "disabler: false".
However, this was broken in commit ab0ffc6a2 ("modules/sourceset: Fix
remaining typing issues", 2022-02-23) which changed logic instead of
just fixing typing issues. This was likely an attempt to avoid using
"dependencies.Dependency" after the "dependencies" field was declared,
but it also broke QEMU.

We are supposed to fallback on the fallback when running the vcstagger,
but instead we errored out during configure.
Fixes regression in commit b402817fb6.
Before this, we used shutil.which || relative paths, and in the latter
case if it could not be found we still wrote out that path but it failed
to run in vcstagger. Now, we use find_program under the hood, so it
needs to be run in non-fatal mode, and if it is not found, we simply
keep the original command string. It's a VCS command, so if we magically
end up finding it at runtime because it was installed after running
configure, that is *fine*.
It is often useful to check the found version of a program without
checking whether you can successfully find
`find_program('foo', required: false, version: '>=XXX')`
Due to misuse of argparse in commit 82492f5d76
it was impossible to use both --datadirs and extra args passed directly
to msgfmt at the same time.
I'm not sure anyone actually knows how argparse works, so misusing it is
easy. What is definitely known is that argparse is NOT a POSIX compliant
parser and doesn't behave the way you'd expect a standards based parser
to handle options. Instead it caters to the easy use case, and hopes and
prays you don't need to do anything too complicated "with the wrong kind
of complicated".
Apparently, this particular type of complicated is when you have mixed
option_arguments and operands while simultaneously passing some operands
as nargs after a --.
It totally breaks, and interprets --datadirs, which is supposed to be an
option_argument, as an operand, eats it up as a msgfmt wrapped argument,
and breaks.
But if you don't pass additional arguments with -- then it interprets
--datadirs after operands as an option_argument. This is what we were
doing.
Instead pass option_arguments before all operands (including the ones
specified via `-- ...`). Add test case to pass meaningless datadirs (we
don't actually care if $GETTEXTDATADIRS is set to something that doesn't
contain gettext data).
- Change `scope` kwarg to `public` boolean default to false.
- Change `side` kwarg to `client` and `server` booleans.
- Document returned values
- Aggregate in a single unit test because have lots of small tests
increases CI time.
Fixes: #10040.
JNI is a more apt name because it currently only supports the JNI. I
also believe that CMake uses the terminology JNI here as well.
JNI is currently the only way to interact with the JVM through native
code, but there is a project called "Project Panama" which aims to be
another way for native code to interact with the JVM.
After implementing a much more extensive Java native module than what
currently exists in the tests, I found shortcomings.
1. You need to be able to pass multiple Java files.
2. Meson needs more information to better track the generated native
headers.
3. Meson wasn't tracking the header files generated from inner classes.
This new function should fix all the issues the old function had with
room to grow should more functionality need to be added. What I
implemented here in this new function is essentially what I have done in
the Heterogeneous-Memory Storage Engine's Java bindings.
In a bunch of cases we create a series of sample libraries named "a",
"b", "c" etc.
This breaks on musl. Originally reported with muon via commit
ca5c371714
and also breaks the testsuite when packaging meson for alpine linux.
libc.so is an existing library which is linked in by default for all the
obvious reasons. You can get away with this on glibc, because that
includes a soversion of "6", but it loads the wrong library on musl.
find_program() can check that for us already, there's no need to
require GNU bash on systems that default to other POSIX shells.
Even though this is the *linuxlike* tests and a POSIX shell is
guaranteed, there is actually no need to require a shell at all. It's
*easier* to use the meson builtin functionality here.
Automatically generate additional variables and write them into the
generated pkg-config file.
This means projects no longer need to manually define the ones they
use, which is annoying for dataonly usages (it used to forbid setting
the base library-relevant "reserved" ones, and now allows it only for
dataonly. But it's bloat to manualy list them anyway).
It also fixes a regression in commit
248e6cf473 which caused libdir to not be
set, and to be unsettable, if the pkg-config file has no libraries but
uses the ${libdir} expansion in a custom variable. This could be
considered likely a case for dataonly, but it's not guaranteed.
This bring us in line with Autotools and CMake and it is useful
for platforms like Nix, which install projects
into multiple independent prefixes.
As a consequence, `get_option` might return absolute paths for some
directory options, if a directory outside of prefix is passed.
This is technically a backwards incompatible change but its effect
should be minimal, thanks to widespread use of `join_paths`/`/` operator
and pkg-config generator module. It should only cause an issue when
a path were constructed by concatenating the value of directory path option.
Also remove a comment about commonpath since we do not use that since
<00f5dadd5b>.

For static library crates that depend on other internal static library
crates, all link_with targets get promoted to link_whole targets. Due to
a bug, only link_with targets are considered when generating a Rust
target for the ninja backend. This made it impossible to link a Rust
static library with another internal Rust static library.
This change fixes that issue by chaining link_whole_targets with
link_targets, just like many other languages within the ninja backend.
