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.
By default, pdb assumes that any command run is python code to be
evaluated, but only if that code isn't a builtin pdb command. You can
force it to be evaluated as python code by prefixing it with `!`.
It's handy to simply name a python variable and have its variable be
printed.
But single letter variables like 's' and 'p' make debugging with pdb
commands (i.e. 's'tep, and 'p'rint evaluated expressions) less
convenient, and potentially confusing.
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
For some (atm unknown) reason mingw Python fails to load some modules
when MSYS2 is removed from PATH, like in this test.
Skip for now to make the test suite pass again. Once
https://github.com/msys2-contrib/cpython-mingw/issues/141 is fixed
this can be reverted.
The wording was a bit confusing and misled at least one person into
thinking it behaved like `str.replace('c', '')` operating on the entire
line. Tweak the wording to be more precise and avoid this confusion.
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.
