It's particularly inscrutable if you do not know where DLLs weren't
found because you don't know what the PATH was in the child process.

For all source `*.py` files installed via either py.install_sources() or
an `install_dir: py.get_install_dir()`, produce `*.pyc` files at install
time. Controllable via a module option.

Previously, it would raise an exception.

When devhelp is enabled, hotdoc generates a devhelp/ subdir that needs
to be installed to /usr/share/devhelp/. Otherwise, the html/ subdir
needs to be installed to /usr/share/doc/<project>/html/

It seems this happens because at some point setuptools imports gettext,
and we have a script by the same name.
In general, this path injection by default is bad news for our use case.
Python 3.11 introduced -P for this reason, but we cannot depend on that.
Instead, check for it first, and delete it, before doing more imports.

The version lookup should be silent. While we're at it, the version
lookup should not be happening more than once, which printing multiple
messages indicated we were doing. Pass the version into the per-file
function rather than looking it up fresh each time.

We write this out as an embedded string to a tempfile in order to run
it, which is pretty awkward. And usually Meson's files are already files
on disk, not packed into a zip, so we can simply run it directly. Since
python 3.7, which is our new minimum, we can handle this well via the
stdlib. (There's also mesonbuild.mesondata, but we do not need
persistence in the builddir.)
This also solves the problem that has always been there, of giant python
programs inside strings occasionally confusing syntax highlighters. Or
even, it would be nice if we had syntax highlighting for this
introspection program. :D

Given the construct `foo = (bar == baz)` some people like parentheses
and some do not. They're pointless and don't mean anything, though. I
don't feel this is particularly helpful to code clarity, tbh, and pylint
now notices this and warns about it in our current pylint config.
I think this is reasonable, so let's remove the odd parens.

fix_jar() tries to remove an existing Class-Path entry from the jar
manifest by postprocessing the manifest and passing it to `jar -um`.
However, `jar -um` can only add/replace manifest entries, not remove
them, and it also complains loudly when replacing an entry:
Dec 13, 2022 7:11:19 PM java.util.jar.Attributes read
WARNING: Duplicate name in Manifest: Manifest-Version.
Ensure that the manifest does not have duplicate entries, and
that blank lines separate individual sections in both your
manifest and in the META-INF/MANIFEST.MF entry in the jar file.
Thus fix_jar() produces one such warning for each entry in the manifest
and accomplishes nothing else.
Use jar -uM instead. This completely removes the manifest from the jar
and allows adding it back as a normal zip member, fixing fix_jar() and
avoiding the warnings.

Due to a deficiency in upstream clang-format, our automatic target for
`ninja clang-format-check` runs clang-format, then compares the bytes of
the file before and after to see if anything changed. If it did change,
we rewrite the file back to its original form and error out.
Since clang-format 10, there is an option to report warnings instead of
writing the reformatted file, and also, to make those warnings fatal.
This is a much better user experience, to see *what* is wrong, not just
that something is wrong, and also gets rid of a pretty gross "modify
your files when you didn't ask for it" behavior that is vulnerable to
getting interrupted.
Let's switch over to the new approach, if we can.

Which adds the `use-set-for-membership` check. It's generally faster in
python to use a set with the `in` keyword, because it's a hash check
instead of a linear walk, this is especially true with strings, where
it's actually O(n^2), one loop over the container, and an inner loop of
the strings (as string comparison works by checking that `a[n] == b[n]`,
in a loop).
Also, I'm tired of complaining about this in reviews, let the tools do
it for me :)

I assume there's no real reason this cannot happen, perhaps if the meson
source directory has one. So we should use Popen_safe for safety
reasons.

Those classes are used by wrapper scripts and we should not have to
import the rest of mesonlib, build.py, and all their dependencies for
that.
This renames mesonlib/ directory to utils/ and add a mesonlib.py module
that imports everything from utils/ to not have to change `import
mesonlib` everywhere. It allows to import utils.core without importing
the rest of mesonlib.

This does force a number of uses of `# pylint: disable` comments, but it
also finds a couple of useless global uses and one place (in the
previous commit) that an easy refactor removes the use of global. Global
is a code smell, so forcing adding a comment to disable helps force
developers to really consider if what they're doing is a good idea.
|
|
The `global` statement is only needed to assign to global variables, not
read or mutate them. So calling `global.mutate()` is fine, but not
`var = foo`, which would otherwise shadow `var`.

gwmi command does not exist any more and is replaced by Get-CimInstance.
See https://github.com/PowerShell/PowerShell/issues/4766.
While at it, use a do..while loop to avoid duplicated lines.

This finds a bunch of places where we can do more efficient string
splitting.

Meson internally knows about many languages and tools, and *FLAGS
variables, and which languages to use them for. Instead of duplicating
this logic, import it from mesonbuild.*
This logic was originally standalone, but now that it is merged into the
Meson tree we can have a single source of truth.

In commit 4ca9a16288f51cce99624a2ef595d879acdc02d8 we added unreliable
support (it warns you if you try it) for gcc-compatible treatment of
uppercase-C files being C++ instead of C. In order to handle it
correctly, we needed to evaluate can-compile by special-casing "C" to
avoid lowercasing it for comparisons.
This didn't cover all cases where we check if "C" is a C++ language
file. We also straight-up check the language of a file (rather than
working backwards to see if a C++ compiler can compile it) when doing
module scanning, and this needs to special-case "C" as well.
We also had one case where we only checked lowercase fortran extensions,
but not lowercase C++ extensions. While we are at it, use lowercase for
C++ as well, except the "C" special case.
Fixes #10629

In Fortran and C++ all the bits we care about are in ASCII. 8-bit
characters can only occur in comments and string literals and we don't
parse those.
|
|
The old implementation assumed a path is of Windows iff the second
character is a colon. However, that is not always true.
First, a colon can be included in a non-Windows path. For example, it is
totally fine to have a directory named ':' on Linux 5.17.0 tmpfs.
Second, a Windows path may start with \\ for UNC or extended length.
Use pathlib to handle all of these cases.

The check for if the project supports the -j flag was needlessly
complex. We support two types of project:
- waf, always supports -j
- make, if GNU, supports -j
We never checked waf, and the make check assumed that the entire
command, rather than just the last component, was "make". It also
neglects "gmake".
Since any possible build command *may* support -j, always run the
--version check. Detect either build command in the output.
|
|
It doesn't matter whether it is make or not, because make, too, supports
setting it via the env. This reduces the use of special cases in the
code.

- Remove duplicated code in mdevenv.py
- Change the limit to 1024 instead of 2048 which is what has been
tested.
- Skip shortening if it is already short enough.
- Skip shortening with wine >= 6.4 which does not seems to have that
limitation any more.
- Downgrade exception to warning in the case WINEPATH cannot be
shortened under 1024 chars, it is possible that it will still work.

Checks "pwsh.exe" in addition to "powershell.exe" and "cmd.exe"
to support PowerShell 7 on Windows. The Powershell 7 support was added
in GStreamer (which is the origin of this script) already via

Along the way, add __future__ annotations where lacking.

Because this is a wrapper script and we could/should do this, we even
have half the infra for it.
