Use common conventions for documentation of shared library version and
soversion. In general, the numeric version part is expected to be first
component of version, so suggest this in the example code.
In commit 83a973ca04 a bunch of strange
changes were made, that were not even tested. Make sure people get the
correct command for running coverage targets.
This patch adds 'depends' keyword to compiler.preprocess().
It allows to execute other targets before doing the preprocessing.
Test-case is added to demonstrate that functionality: it
generates the header before preprocessing the C source that
uses that generated header.
Thanks to @bruchar1 for getting this patch to work.
For Clang, we now pass -D_GLIBCXX_DEBUG=1 if debugstl is enabled, and
we also pass -D_LIBCPP_HARDENING_MODE=_LIBCPP_HARDENING_MODE_DEBUG.
Per https://discourse.llvm.org/t/building-a-program-with-d-libcpp-debug-1-against-a-libc-that-is-not-itself-built-with-that-define/59176/3,
we can't use _LIBCPP_DEBUG for older Clang versions as it's unreliable unless
libc++ was built with it.
We choose MODE_DEBUG for stldebug while building with assertions will do
MODE_EXTENSIVE.

None of the options set here affect ABI and are intended for detecting constraint
violations.
For GCC, we simply need to set -D_GLIBCXX_ASSERTIONS.
For Clang, the situation is far more complicated:
* LLVM 18 uses a 'hardened mode' (https://libcxx.llvm.org/Hardening.html).
There are several levels of severity available here. I've chosen
_LIBCPP_HARDENING_MODE_EXTENSIVE as the strongest-but-one. The strongest
one (_DEBUG) doesn't affect ABI still but is reserved for stldebug.
* LLVM 15 uses a similar approach to libstdc++ called '_LIBCPP_ENABLE_ASSERTIONS'
Note that LLVM 17 while in development had fully deprecated _LIBCPP_ENABLE_ASSERTIONS
in favour of hardened, but changed its mind last-minute: https://discourse.llvm.org/t/rfc-hardening-in-libc/73925/4.

Especially relevant for users of Ubuntu 22.04 which has packages for
Qt 6.2 and Meson 0.61.

CLion was not mentioned in the list of IDE integrations. This commit adds it, also
adds a “3rd party" prefix to the Meson Syntax Highlighter plugin to indicate that it doesn't come from JetBrains, and sorts the list alphabetically.
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 properly sets the project version in projects meson generates from
cmake projects. This allows dependency fallbacks to properly check the
version constraints in dependency calls when falling back to a cmake
subproject. Before this would fail, because the project version was
undefined.
If an annotation could not be resolved, it's classified as a "missing
import" and our configuration ignored it:
```
Skipping analyzing "mesonbuild.backends": module is installed, but missing library stubs or py.typed marker
```
As far as mypy is concerned, this library may or may not exist, but it
doesn't have any typing information at all (may need to be installed
first).
We ignored this because of our docs/ and tools/ thirdparty dependencies,
but we really should not. It is trivial to install them, and then
enforce that this "just works".
By enforcing it, we also make sure typos get caught.
This is needed now that str.format() is not allowing it any more. It is
also more consistent with other objects that have that method as well,
such as build targets.

Releases have been happening an average of once every 90 days for the
past two years (since 0.60.0). If we just look at releases since 1.0.0,
the average is over 100 days.
It was previously impossible to do this:
```
dep.get_pkgconfig_variable(
'foo',
define_variable: ['prefix', '/usr', 'datadir', '/usr/share'],
)
```
since get_pkgconfig_variable mandated exactly two (if any) arguments.
However, you could do this:
```
dep.get_variable(
'foo',
pkgconfig_define: ['prefix', '/usr', 'datadir', '/usr/share'],
)
```
It would silently do the wrong thing, by defining "prefix" as
`/usr=datadir=/usr/share`, which might not "matter" if only datadir was
used in the "foo" variable as the unmodified value might be adequate.
The actual intention of anyone writing such a meson.build is that they
aren't sure whether the .pc file uses ${prefix} or ${datadir} (or which
one gets used, might have changed between versions of that .pc file,
even).
A recent refactor made this into a hard error, which broke some projects
that were doing this and inadvertently depending on some .pc file that
only used the second variable. (This was "fine" since the result was
essentially meaningful, and even resulted in behavior identical to the
intended behavior if both projects were installed into the same prefix
-- in which case there's nothing to remap.)
Re-allow this. There are two ways we could re-allow this:
- ignore it with a warning
- add a new feature to allow actually doing this
Since the use case which triggered this bug actually has a pretty good
reason to want to do this, it makes sense to add the new feature.

When a user invokes the scan-build target that Meson generates
all subprojects are included in the resulting report. This commit
modifies the invocation of scan-build to exclude all bugs that
scan-build finds in the subprojects from the final report.
A release note has also been added describing the changed behaviour.
Do as we do for MALLOC_PERTURB and set a sensible value for both ASAN_OPTIONS
and UBSAN_OPTIONS to abort on failure and give more helpful output at the
same time. We do not set these options if the user has exported a value
themselves to allow override.
In the last week alone, I've observed two cases where people were expecting
sanitizers to abort on failure and were surprised when it didn't:
1) 252d693797
2) c47df433f7
Correct this - which is in-line with meson's DWIM/DTRT philosophy.

Which allow passing arguments specifically to the static or shared
libraries.
For design, this is all handled in the interpreter, by the build layer
the arguments are combined into the existing fields. This limits changes
required in the mid and backend layers
Way back in Meson 0.25, support was added to `vala_args` for Files.
Strangely, this was never added to any other language, though it's been
discussed before. For type safety, it makes more sense to handle this in
the interpreter level, and pass only strings into the build IR.
This is accomplished by adding a `depend_files` field to the
`BuildTarget` class (which is not exposed to the user), and adding the
depend files into that field, while converting the arguments to relative
string paths. This ensures both the proper build dependencies happen, as
well as that the arguments are always strings.
Since the previous commit allows for more scenarios with name
collisions, it makes sense to expand the compile command so that it can
also take into account suffixes. i.e. meson compile -C build foo.exe can
now work if the executable has an exe suffix along with being named foo.
When checking target names, meson explictly forbids having multiple
targets with the same name. This is good, but it is strict and it is
impossible to have targets with the same basename and differing suffixes
(e.g. foo and foo.bin) in the same directory. Allow this for executables
by including the suffix (if it exists) in the interal target id. So foo
would be foo@exe and foo.bin would be foo.bin@exe.
