This has no actual effect on the codebase as type checkers (still)
support both and negligible effect on runtime performance since
__future__ annotations ameliorates that. Technically, the bytecode would
be bigger for non function-local annotations, of which we have many
either way.
So if it doesn't really matter, why do a large-scale refactor? Simple:
because people keep wanting to, but it's getting nickle-and-dimed. If
we're going to do this we might as well do it consistently in one shot,
using tooling that guarantees repeatability and correctness.
Repeat with:

Make them into real type annotations. These are the only ones that if
automatically rewritten, would cause flake8 to error out with the
message: "E128 continuation line under-indented for visual indent".
ExternalProgram and CustomTarget have some use cases for producing
subclassed interpreter holders with more specific types and methods. In
order for those subclasses to properly refer to their held_object, we
need a shared base class that is still generic, though bound.
For the derived held objects, inherit from the base class and specify
the final types as the module-specific type.
- allow defines with leading whitespace
- always do replacement for cmakedefine
- output boolean value for cmakedefine01
- correct unittests for cmakedefine
- add cmakedefine specific unittests
clang has supported gcc syntax since version 3.3.0 from 10 years ago.
It's better than its own version because it takes a "when" verb which
allows us to explicitely ask for "auto". This is useful when overriding
flags that came from elsewhere.
Before this patch, meson was just treating b_colorout="auto" as "always".
meson tests enable PYTHONWARNDEFAULTENCODING by default and
make EncodingWarning fatal too.
Starting with Python 3.11 CPython not only warns if no encoding is passed
to open() but also to things like subprocess.check_output(). This made
the call in vsenv.py fail and in turn made test_vsenv_option fail.
check_output() here calls a .bat file which in turn calls vcvars. I don't
know what the encoding is supposed to be used there, so just be explicit
with the locale encoding to silence the warning.
When an installed static library A links to an internal static library B
built using a custom_target(), raise an error instead of a warning. This
is because to be usable, A needs to contain B which would require to
extract the archive to get its objects files.
This used to work, but was printing a warning and was installing a
broken static library, because we used to overlink in many cases, and
that got fixed in Meson 1.2.0. It now fails at link time with symbols
from the custom target not being defined. It's better to turn the
warning into a hard error at configure time.
While at it, noticed this situation can happen for any internal custom
or rust target we link to, recursively.
get_internal_static_libraries_recurse() could be called on CustomTarget
objects which do not implement it, and even if we did not call that
method, it would still fail when trying to call extract_all_objects() on
it.

Improve the error message when a build target is assigned as dependency
of another build target, which allows to better pinpoint where the issue
lies on.
In the example that follow, modules/meson.build:294 is in a for loop
creating library targets from an array of dictionary, and doesn't point
to the location where interop_sw_plugin is assigned with vlc_opengl:
Before:
modules/meson.build:294:17: ERROR: Tried to use a build target as a dependency.
You probably should put it in link_with instead.
After:
modules/meson.build:294:17: ERROR: Tried to use a build target vlc_opengl as a dependency of target interop_sw_plugin.
You probably should put it in link_with instead.
It would probably be best to directly pinpoint where the assignment was
made but it's probably harder so start simple by saying what is
concerned by the error.
If we have a build- or host-architecture compiler, we can detect mips64
vs. mips by the fact that mips64 compilers define __mips64. However,
machine_info_can_run() doesn't provide any compilers, because it is
interested in the architecture of the underlying kernel. If we don't
return mips64 when running on a mips64 kernel, machine_info_can_run()
will wrongly say that we can't run mips64 binaries.
If we're running a complete 32-bit mips user-space on a mips64 kernel,
it's OK to return mips64 in the absence of any compilers, as a result
of the previous commit "environment: Assume that mips64 can run 32-bit
mips binaries".

The relationship between mips64 and mips is similar to the relationship
between x86_64 and x86. Representing it here is necessary so that we
will not require an exe_wrapper when cross-compiling for 32-bit mips on
mips64, or when a complete 32-bit mips user-space runs on a 64-bit kernel
without using linux32 to alter uname(2) to pretend to be 32-bit.

We support this in a machine file:
```
[binaries]
pkgconfig = 'pkg-config'
pkg-config = 'pkg-config'
```
and you can use either one, because internally we look up both. If you
only set *one* of them, this plays awkwardly with setting $PKG_CONFIG,
since we don't know which one you set in the machine file and the
*other* one will be initialized from the environment instead.
In commit 22df45a319 we changed program
lookup of config-tool style dependencies to use the regular tool names
and only fall back on the strange internal names. This affected the
pkg-config class too.
The result is that instead of preferring `pkgconfig =` followed by
$PKG_CONFIG followed by `pkg-config =`, we inverted the lookup order.
This is a good idea anyway, because now it behaves consistently with
`find_program('pkg-config')`.
Unfortunately, we documented the wrong name in a bunch of places, and
also used the wrong name in various testsuite bits, which meant that if
you set $PKG_CONFIG and then ran the testsuite, it would fail.
Correct these references, because they are buggy.
One test case expected to find_program() a native copy for convenience
of testing against natively installed glib. Force it to resolve a native
copy.
On my project, this function was a bottleneck in setup time.
By properly caching it, the cumtime for this function
went from 26s to 4.3s when I profiled it.
When performing isinstance checks, an identity comparison is
automatically done, but we don't use isinstance here because we need
strict identity equality *without allowing subtypes*.
Comparing type() == type() is a value comparison, but could produce
effectively the same results as an identity comparison, usually, despite
being semantically off. pycodestyle learned to detect this and warn you
to do strict identity comparison.
We allow custom_target() but check for it based on hasattr, ever since
the initial implementation way back in the day, in commit
66a6ea984b. This is a bit broken because
various objects might support that but still aren't supposed to work. We
can actually just use isintance checks like we do immediately above,
which are more accurate and avoid crashes on things that aren't even
targets at all, like run_target(). Although custom_target indexes are
actually targets those didn't work either.
Fixes#9648
This fixes two issues in constructing the default installation path
when install_dir is not specified:
- inside a subproject, install_data() would construct the destination
path using the parent project name instead than the current project
name,
- when specifying preserve_path, install_data() would construct the
destination path omitting the project name.
Fixes#11910.
The function name adheres to the pattern used by many other Meson DSL
implementation methods, thus stating that this is the implementation
of the functionality without argument validation is not very useful.
The docstring is separated from the function declaration by a blank
line. Removing the docstring avoids having to decide if the blank line
should be there or not.
The only real differences between these generators is the file extension
and the templates themselves. We can uses a shared abstract class
with a few abstract properties to provide all of this to the same base
class. This results in less code duplication and easier maintanence.
I've made a few cleanups to the shared template:
- use `str.capitalize()` instead of `str.upper()[0] + str[1:]`
- use `open` as a context manager
- use f-strings
- put some duplicate calculations in the initializer
