When hdf5 is built with cmake instead of autotools, it makes a number of
weird changes. What we care about in particular is that h5cc exists but
doesn't work -- it happily ignores -show and tries to compile stuff,
then leaves us with a dependency that has no libraries, and fails when
running `ninja`.
See: #12748
This replaces all of the Apache blurbs at the start of each file with an
`# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing
uses to be consistent in capitalization, and to be placed above any
copyright notices.
This removes nearly 3000 lines of boilerplate from the project (only
python files), which no developer cares to look at.
SPDX is in common use, particularly in the Linux kernel, and is the
recommended format for Meson's own `project(license: )` field

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:
```
com2ann mesonbuild/
```
Simply store the module it is expected to be found in. That module then
appends to the packages dict, which guarantees mypy can verify that
it's got the right type -- there is no casting needed.
We do some magic to figure out what names of pkg-config dependencies to
even search for. This magic simply checked for `pkg-config` the $PATH
executable, which was broken in a variety of ways and had a comment to
that effect.
It is, after all, "safe". ;) That's why it exists. There's no reason to
think listing all pkg-config entries cannot print unicode descriptions,
it's absolutely possible, and we should handle it properly if we
encounter it.
In a couple of spots, kwargs.get('static', False) was being
unneccesarily used. In these spots, we can just use self.static instead
which is already inherited from the ExternalDependency. In additional,
the python system dependency oddly has a kwargs.get('static', False)
line which overrides the self.static in that dependency for no real
reason. Delete this line too.
Depending on whether hdf5 is compiled with parallel support, the
same config-tool program may be installed with a mysterious "p" in the
name. In this case, dependency lookup will totally fail, unless of
course you use the superior pkg-config interface in which case you get a
predictable name.
Work around this insanity by checking for both types of config-tool
name.
Fixes#9555
All changes were created by running
"pyupgrade --py3-only --keep-percent-format"
and committing the results. I have not touched string formatting for
now.
- use set literals
- simplify .format() parameter naming
- remove __future__
- remove default "r" mode for open()
- use OSError rather than compatibility aliases
- remove stray parentheses in function(generator) scopes
hdf5's config-tools will not show compile arguments (including the
include directory) if called without `-c`. Make sure to get both the
compile and link arguments.
Instead of the default ones, this is especially important when cross
compiling or when using compilers that aren't compatible with the
default ones.
squash! dependencies/hdf5: Use the actual system compilers
Currently PkgConfig takes language as a keyword parameter in position 3,
while the others take it as positional in position 2. Because most
dependencies don't actually set a language (they use C style linking),
using a positional argument makes more sense. ExtraFrameworkDependencies
is even more different, and duplicates some arguments from the base
ExternalDependency class.
For later changes I'm planning to make having all of the dependencies
use the same signature is really, really helpful.
This addresses various real-world problems with HDF5 pkg-config, including
* hdf*.pc with package versions as part of the filename
* malformed hdf*.pc missing the commonly-used HDF5 HL module
---
Additionally, this refactors more complicated dependencies such as
HDF5 and OpenMPI. This may help us deduplicate internal dependency
code in the future.
