Don't leave the subproject tree in a broken / conflicting state. The
user is most likely not a git expert who will know what magic command
to run to fix their source tree.
Which allow passing arguments specifically to the static or shared
libraries.
For design, this is all handled in the interpreter, by the build layer
the arguments are combined into the existing fields. This limits changes
required in the mid and backend layers
`java_args` is only valid for `jar()` (and `build_target()`, but that's
deprecated), while all other language args are invalid for `jar()`. This
deprecates all of those arguments, that shouldn't be allowed, and
provides useful error messages. As an advantage, this avoids generating
useless `java_static_args` and `java_shared_args`.
In order to get useful error messages for both build_target and
executable + *library, we need to separate LIBRARY and BUILD_TARGET a
bit.
This also moves the repacking into the interpreter, making the build
implementation simpler and removing a layering violation. This also
makes use a defaultdict to remove the need to call `.get()`
Way back in Meson 0.25, support was added to `vala_args` for Files.
Strangely, this was never added to any other language, though it's been
discussed before. For type safety, it makes more sense to handle this in
the interpreter level, and pass only strings into the build IR.
This is accomplished by adding a `depend_files` field to the
`BuildTarget` class (which is not exposed to the user), and adding the
depend files into that field, while converting the arguments to relative
string paths. This ensures both the proper build dependencies happen, as
well as that the arguments are always strings.
This most likely happens when the source archive has files which take
advantage of case sensitivity, and someone is unfortunate enough to have
to work with broken operating systems that do not have the capacity to
use modern technology, like the 1970s invention of case sensitive
filesystems.
For example, Windows and macOS both have retrocomputing environments,
where case sensitive abilities were carefully removed from modern
filesystems in order to share the delights of classical computing with
the masses.
On such systems, innocent tarballs fail to extract with:
```
OSError: [Errno 22] Invalid argument: 'C:\path\to\file'
```
thereby demonstrating Microsoft's unbounded and enthusiastic love for
users (who are, universally, retrocomputing fans).
n.b. there is, begrudgingly, a secret option for crazy people who hate
retrocomputing to enable modern 1970s computing on Windows systems.
Naturally, no one with any sense would ever use this, and it is rightly
left in its sensible default in for example Github Actions.
Fixes#12344
lcov 2.0 deprecates `--rc lcov_branch_coverage=1` for `--rc branch_coverage=1` and
gives an error when an exclude is used on a non existing directory.
I added a version check for lcov and removed the subprojects directory from the
exclusion list if it does not exist.
Fixes#11995
Since the previous commit allows for more scenarios with name
collisions, it makes sense to expand the compile command so that it can
also take into account suffixes. i.e. meson compile -C build foo.exe can
now work if the executable has an exe suffix along with being named foo.
When checking target names, meson explictly forbids having multiple
targets with the same name. This is good, but it is strict and it is
impossible to have targets with the same basename and differing suffixes
(e.g. foo and foo.bin) in the same directory. Allow this for executables
by including the suffix (if it exists) in the interal target id. So foo
would be foo@exe and foo.bin would be foo.bin@exe.
The MSVC code is extremely confusing, and it turns out it actually
constructs debug (pdb) files names/path independently in separate
places. This is really hard to parse. Instead, refactor it so that the
source of the debug filename is within the target itself
(get_debug_filename). Add a couple of generic methods to retrieve the
full path of the debug filename name in the backend and use that when
needed.
On python >=3.8, this information is expected to be encoded in the
sysconfig vars.
In distutils, it is always necessary to link to libpython on Windows;
for posix platforms, it depends on the value of LIBPYTHON (which is the
library to link to, possibly the empty string) as generated by
configure.ac and embedded into python.pc and python-config.sh, and then
coded a second time in the distutils python sources.
There are a couple of caveats which have ramifications for Cygwin and
Android:
- python.pc and python-config.sh disagree with distutils when python is
not built shared. In that case, the former act the same as a shared
build, while the latter *never* links to libpython
- python.pc disagrees with python-config.sh and distutils when python is
built shared. The former never links to libpython, while the latter do
The disagreement is resolved in favor of distutils' behavior in all
cases, and python.pc is correct for our purposes on python 3.12; see:
https://github.com/python/cpython/pull/100356https://github.com/python/cpython/pull/100967
Although it was not backported to older releases, Cygwin at least has
always patched in a fix for python.pc, which behavior is now declared
canonical. We can reliably assume it is always correct.
This is the other half of the fix for #7702
Since 3.10.3, Debian finally started patching sysconfig with custom
paths, instead of just distutils. This means we can now go use that
instead. It reduces our reliance on the deprecated distutils module.
Partial fix for #7702
We do not use setuptools for anything, and only lightly use distutils.
Unpredictable issues can occur due to setuptools monkey-patching, which
interferes with our intended use. Tell setuptools to simply never get
involved.
Note: while it's otherwise possible to check if the probe is run using
sys.executable and avoid forking, setuptools unconditionally injects
itself at startup in a way that requires subprocess isolation to
disable.
ExternalProgram currently assumes that if a command is passed it exists
and can be used as is. In case we extract the path from pkgconfig the
path might not exist, on Windows it might be missing the ".exe" suffix.
By passing the variables as a name ExternalProgram will validate that
the command exists at configure time and will fail if not, and it will
try to fixup the command by appending .exe etc.
Fixes#12271
This differentiates export_dynamic being explicitly set to False from it
being unset. This allows us to deprecate explicitly setting
export_dynamic to false, but setting implib. This is already the case in
the other direction, if implib is False but export_dynamic is enabled
then we get a hard error.
This also moves the validation up to the Interpreter and out of the
build level.
This is to allow passing the path share/cmake/ as cmake_prefix_path.
This is a case supported by cmake and is relied on by PyTorch.
The cmake prefix of PyTorch can be found by running:
python -c 'import torch.utils; print(torch.utils.cmake_prefix_path)'
you will see something like below from the above command:

However, meson currently filters this directory out by `_preliminary_find_check`. As a result, doing
torch_dep = dependency('Torch')
will fail, even if you set `cmake_prefix_path` with the value returned by PyTorch.

In commit dd22546bdd the various
typed_pos_args for different BuildTarget functions was refactored into a
common tuple of types.
It overlooked the fact that jar specifically does NOT accept the same
types, and began to allow passing structured_sources in.
