This is useful for totally terrible stuff that we really dislike, but
for some reason we are afraid to just use `mlog.deprecation()` and
unconditionally tell people so.
Apparently this is because it is totally absolutely vital that, when
telling people something is so broken they should never ever ever use it
no matter what, ever... we can't actually tell them that unless they
bump the minimum version of Meson, because that's our standard way of
introducing a **version number** to tell them when we first started
warning about this.
Sigh. We really want to warn people if they are doing totally broken
stuff no matter what version of Meson they support, because it's not
like fixing the thing that never worked is going to suddenly break old
versions of meson.
So. Here's some new functionality that always warns you, but also tells
you when we started warning.

The version output scraping for identifying strings checked for "IFORT"
in parentheses after the executable name, which is probably a mistake by
Intel. Current versions of ifx have "IFX" in parentheses there.
Detect both.

When a project targets a dev version of Meson (e.g. 1.1.99) for
experimenting, this allows to use:
project(..., meson_version: '>=1.2.0')
It avoids getting warnings when using FeatureNew for features introduced
in 1.2.0.

Specifically, when those files can be created by a build rule with one
version of meson.build, and created as e.g. a shared_library alias
symlink in another version of meson.build, the cleandead command will
delete important files just because they don't happen to be created by
ninja itself.
Work around this by making a dummy rule that exists solely to insert the
files into the build graph to trick ninja into not deleting them.
Closes #11861

Fixes an issue with rust.bindgen if a cmake LLVM dependency with the
system include_type is getting used as a dependency.

This converts a Cargo TOML file into Meson AST

This uses a recursive descent parser + lexer to create an IR from cfg()
expressions, which it then converts into meson IR.

|
|
This is a helper, currently only used by cargo. It could be moved later
if there are other users.

Azure pipelines is removing python2 from the hostedtoolcache, see
https://github.com/actions/runner-images/issues/7401
We want to test that meson can still build modules for it, anyway.
|
|
If py2 is not found *and* the compiler is MSVC, we didn't take into
account that py2 is not found. This also meant that we didn't take into
account the expected count when it *is* found, because the python module
has a better finder than just "is the binary on PATH".
|
|
We don't use parentheses for the if function, because it's not a
function.
|
|
This is now fixed upstream and expected to be backported to the next
point release.

It's a lot more readable to not repeat big arrays.

In commit 89146e84c9eab649d3847af101d61047cac45765 we added some
complicated code to verify the llvm framework's "combination" matrix
lookup. It expects to find llvm with both cmake and config-tool, with
the same version. But the sanity check is wonky -- it checks that both
have the same found status, instead, so if both are not found then we
proceed to try to convert the string "unknown" to a mapping of semver
integers, and this is guaranteed to fail.
This can happen for example if the system llvm exists in the general
case, but actual modules cannot be found because the system llvm does
not distribute static modules. For example, this is the case on Gentoo.
Abort more obviously by just insisting that both be found. If they
aren't both found, then investigative efforts know to look at why they
weren't found.

When retrieving variables from the tool, log some debug output the same
way that pkg-config does.

include directory
e.g. QtQml with Qt 6.4.0 referencing QtQmlIntegration is one such example
|
|
rustc enables PIC by default and Meson currently has no way to force
disabling PIC, it can only force enable or use compiler's default.
|
|
This override transparently upgrades anyone using it to this better
functionality.

py.find_installation().dependency() was not logging whether it is found
or not. Use find_external_dependency() for consistency.

This fallbacks to short commit id in case the git repository does
not contain any annotated tag, for example before the first release of a
project.

- Include BaseNode position in hash methods, integer is the most
straightforward way of differentiating nodes.
- Exclude non hashable fields from hash method.
- Avoid using default values in BaseNode that way subclasses can have
fields wihtout default value without repeating init=False.
- Nodes that does not add fields does not need `@dataclass`.
- Make all node types hashable because they can be used for feature_key
in FeatureCheckBase.use().
- Remove unused type annotations
|

This makes use of dataclasses, but without a dataclass generated
initializer. This means that we get nice `__repr__` and `__eq__` methods
without having to type them by hand.
Pylance understands `dataclass(init=False)`, but mypy doesn't.

Where it belongs. Otherwise it isn't rendered correctly

Replace a long comment explaining that we need StringProtocol, with
StringProtocol
|
|
This is a pretty common pattern in python (the standard library uses it
a ton): A class is created, with a single private instance in the
module, and then it's methods are exposed as public API. This removes
the need for the global statement, and is generally a little easier to
reason about thanks to encapsulation.
|
|
This comment is out of date, we have StringProtocol which is exactly
what we wanted, and it's part of TV_Loggable already
|
|
This was never meant to be public API, log(once=True) is for that.

We actually do not and should not care about wrap-mode at all for this.
We want to cache dependency lookups whenever humanly possible, but only
use them in cases where we would anyways be using them -- which in
particular means if we said to force a subproject fallback for this dep,
we want to bypass the cache.
Currently, we handle this by always looking up the cache for all
dependencies, but clearing the cache at startup if a reconfigure means
we are changing our resolution strategy. This is bad -- we might have
many dependencies that are worth caching, and only one dependency that
should stop being cached and use a subproject instead.
The simple solution is to handle the forcefallback case when doing a
cache lookup, and not do a cache lookup at all. Now we don't have to
nuke the entire cache. In fact, if a future reconfigure changes the
forcefallback state back to not being forced, we can reuse the original
cached dependency, which is still there.
Closes #11828

ninja's configured command for regenerating a build directory on any
action that *requires* reconfiguring, specifies the source and build
directories as they were known during initial project generation. This
means that if the build directory is no longer the *same* build
directory, we will regenerate... the original location, rather than the
location we want.
After that, ninja notices that build.ninja is still out of date, so it
goes and reconfigures again. And again. And again.
This is probably broken intentions, but endless reconfigure loops are a
kind of evil beyond all evils. There are no valid options here
whatsoever other than:
- doing what the user actually meant
- spawning a clear error message describing why meson refuses to work,
then exiting with a fatal error
But it turns out that it's actually pretty easy to do what the user
actually meant, and reconfigure the current build directory instead of
the original one. This permanently breaks the link between the two.

Fedora's java package no longer supports 7.

In this case, PEP 668 was created to allow a thing that Debian wanted,
which is for `pip install foobar` to not break the system python. This
despite the fact that the system python is fine, unless you use sudo pip
which is discouraged for separate reasons, and it is in fact quite
natural to install additional packages to the user site-packages.
It isn't even the job of the operating system to decide whether the user
site-packages is broken, whether the operating system gets the answer
correct or not -- it is the job of the operating system to decide
whether the operating system is broken, and that can be solved by e.g.
enforcing a shebang policy for distribution-packaged software, which
distros like Fedora do, and mandating not only that python shebangs do
not contain `/usr/bin/env`, but that they *do* contain -s.
Anyway, this entire kerfuffle is mostly just a bit of pointless
interactive churn, but it bites pretty hard for our use case, which is a
container image which is fortunately tested before deployment, so
instead of failing to deploy because of theoretical conflicts with the
base system (we specifically need base system integration...) we fail to
deploy because 5 minutes into pulling apt updates at the very beginning,
pip refuses point-blank to work. I especially do not know why it is the
job of the operating system to throw errors intended for interactive
users at people baking "appliance" containers who cannot "break" the
system python anyway.
Fix this by doing what Debian and Ubuntu should both have done from the
beginning, and opting containers out of this questionable feature
entirely.
Note that CI images may still not actually complete their build/test
cycle and be updated, because e.g. LLVM 16 issues tracked by #11642 or
glib ASAN issues tracked by #11754.

This issue was encounetered while working on a contribution to nixpkgs.
Nix allows the store to be installed on a separate, case-sensitive APFS
volume. When the store is on a case-sensitive volume, these tests fail
because they try to use `foundation` instead of `Foundation`.

fix package ordering to so Q* and r* packages are in alphabetical order.

This can be the longest part of the entire test process, often with no
benefit because we already know the environment is sane. So, let's have
an option save some time.
|

Allow the use of wildcards (e.g. *) to match test names in `meson test`.
Raise an error is given test name does not match any test.
Optimize the search by looping through the list of tests only once.

- Do not hardcode terminal width of 100 chars, that breaks rendering on
smaller terminal. It already uses current console width by default.
- Disable progress bar when downloading from msubprojects because it
fetches multiple wraps in parallel.
- Scale unit when downloading e.g. MB/s.
- Do not display rate when it's not a download.
- Do not display time elapsed to simplify the rendering.
