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.

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
Since it's deprecated anyway, we don't really want to plumb it all the
way down into the build and backend layers. Instead, we can just turn
it into a `win_subsystem` value in the interpreter if `win_subsystem`
isn't already set.
When the pkgconfig module is imported, but not used, it will insert None
on the end of the devenv list. This list is not expected to contain
None, and causes Meson to crash. This can happen in complex build setups
(reported from mesa), where pkgconfig is only used in some
configurations
Fixes: #12032
We need to verify that we don't produce multiple rules for the same
file. This uniqueness check is easy to do with a set, but the original
old implementation used a dict with True as the value. This isn't a
terrible way to implement a set -- we do it for our own internal
OrderedSet implementation, even, and back in prehistory (python 2.3) the
standard library's set type was one. But it was deleted and replaced
with a fast native implementation, and we should too.
I originally refactored this wrapper function in commit
dd2f1c4c57 and at the time I made it take
the following call pattern:
```
self.create_phony_target(self.all_outputs, ..., implicit_outs=None)
```
I am not sure *why*. There are a couple problems here:
- When creating a phony target, there are never implicit outs and we never
try to create them.
- It's invalid to call it without self.all_outputs as the first argument,
so really we should just use that directly.
This made the function signature pointlessly longer and more
complicated.
We always expect the args parameter in the wrapped function to
eventually receive a tuple due to reasons. But in one specific optargs
condition we passed it along without any fixup at all.
We know exactly what type we need, since the interpreter function is
correctly typed and thinly wraps over this. But we didn't even get the
container type correct. :(
This would be either the value `kwargs['install']`, or `False`. There
isn't any case that `BuildTarget.need_install` handles that
`BuildTarget.install` doesn't handle, if we just initialized it
correctly. So, just set Target.install correctly in the super
initializer, and do away with need_install.
When running setup with `--profile-self` option,
there are currently no logs after "Found ninja...". However, there are
still some lengthy processes for generating targets and ninja.build.
This add more log entries, when profiling, only for the purpose of
displaying the timestamps of the different steps in ninja generation.
Jar has a very low set of overlap with other target types, including
that jar sources *must* be .java, and no other target allows .java
sources. As such, the difficulty in crafting a useful `build_target`
invocation that allows both `jar` and anything else is high, and the
usefulness is dubious. Just use `jar()` directly instead.
This depends on the changes to make all of the jar() specific keyword
arguments be handled by typed_kwargs so that the deprecation messages
are correct and consistent.
