In commit 928078982c a good error message
about the directory not being a valid build directory, was replaced by a
worse message.
In commit abaa980436 the error message was
replaced by a traceback when trying to load the coredata before checking
if it was a build directory.
Revert back to using the helper function with the good error message.
Reorganize code so that we check basic things first, and do less work
before detecting errors.
Fixes#9584
Due to the support for specifying version as files('VERSION'), we need
to internally accept an array, since that is what files() returns.
Before that, we didn't accept arrays, and after that, we don't intend to
accept generic arrays, only arrays as a side effect of files(). So
tighten the typechecking to ensure that that is what we actually get.
If the found python returns None from sysconfig.get_config_var('LIBPC')
then we cannot (and don't) set PKG_CONFIG_LIBDIR from it. In fact, we
can virtually guarantee we won't find a PkgConfigDependency either,
because any python that doesn't have a LIBPC is presumably not installed
to the system pkg-config directory (maybe it's an isolated relocatable
install, maybe it just doesn't have pkg-config support for who knows
what reason).
Trying to find one anyway using pkg-config's builtin search paths can
unexpectedly succeed, though, by finding a completely unrelated python
installation installed to a system location, which isn't the one we are
actually building for.
Instead, return early so that we use the system dependency class
fallback.
While we are at it, add back the debug messages from #3989 which got
removed.
There is the problem of the annotations themselves, then there is
the problem with depends being mutated. The mutation side effect is a
problem in itself, but there's also the problem that we really want to
use Sequence, which isn't mutable.
This is currently allowed, and is used in at least a few projects. It
was not intended to work or documented, but it does and since it is in
use a full deprecation period must be used. A warning has also been
added for values < 0, which have surprising behavior.
This removes the ability to use ConfigurationData as a dict, but
restricting the inputs to `str | int | bool`. This may be a little too
soon for this, and we may want to wait on that part, it's only bee 8
months since we started warning about this.
This is a layering violation, we're relying on the way the interpreter
handles keyword arguments. Instead, pass them as free variables,
destructuring in the interpreter
