Do not run tests that use integers in versions with compiler that do
not support them.
Old versions of GDC supported plain integers in version and debug
strings but they are deprecated and GDC 13 hard errors on them.
These result in very large binaries when linked, and are not generally
useful. A user can turn them back on by passing `-C overflow-checks=yes`
manually via `-Drust_args` or the `RUSTFLAGS` environment variable

In order to pass a File object down into the compiler impl and compile
it, we cannot pass a string with the filename, and we cannot either pass
the File object as-is, since it relies on being given Environment
attributes to calculate the relative location. So we build a fresh File
object as an absolute path.
But the code to do this was totally broken. Instead of using the File
method to get an absolute path, we used one that expected to create
builddir-relative paths... and then gave it the absolute source dir as
the "relative path portion" prefix. This worked by accident as long as
it wasn't a built File, but if it was a built file then we intentionally
didn't include that prefix -- which was wrong anyway, since we need the
build directory!
Use the correct method to get an absolute path in all cases, and emit a
warning if it was a built file. This never worked. Sometimes it crashed,
sometimes it silently returned false.

GCC 12.3 and Clang 16 support -std flags for c++23/c++2b. The unreleased
GCC 14 and Clang 17 will support -std flags for c++26/c++2c.

The c++23 mappings apply to current production compilers (GCC, Clang).
None of the production c++ compilers support c++26 flags yet, but this
mapping will be ready once they do.

On windows, meson would mix posix and windows dir separators in the
computed PACKAGE_RELATIVE_PATH.
Here we force posix directory separator even on Windows. This matches
the CMake behavior and fixes interpretation of the resulting path.

Some macos libraries use arm64e instead of arm64 as architecture. Due to the
string replace approach taken so far, we'd end up with aarch64e as
architecture, which the rest of meson doesn't know.
Move architecture mapping to map whole architecture names and add arm64e ->
aarch64 mapping.
This change doesn't touch the case for armv7[s], where we add arm, rather than
replace armv7[s], but it's certainly not in line with the other mappings.

By specifiying explicit encodings, we can silence warnings like:
/__w/meson/meson/test cases/common/100 postconf with args/postconf.py:15: EncodingWarning: 'encoding' argument not specified
with open(input_file) as f:
in CI.
Replace unencodable XML chars with their printable representation, so
that, xmllint can parse test outputs without error.

Cython historically, when asked to print the version and exit
successfully, would do so on stderr, which is weird and inconsistent.
Recently, it fixed this UX bug by printing on stdout instead:
https://github.com/cython/cython/issues/5504
This then broke meson detection because we assumed it was on stderr due
to historically being there:
https://github.com/scipy/scipy/issues/18865
Cython is right, and shouldn't have to revert this reasonable change for
backwards compatibility. Instead, check both.
There are some new(er) methods that have not version reference, so add
the missing ones in order to be properly notified when targetting older
meson versions.

Instead of hardcoding any values, hardcode what we think the most likely
implementation is, and check that first. It was pointed out that while
for example, Apple only provides libc++ and supports that for xcode, a
user could install a custom environment (such as homebrew) which uses
it's own copy of libstdc++, and we need to account for that. This means
that a library search will be done, but only once and the result will be
cached, on all systems.
It is not the primary purpose of mtest, and it ends up mingled with a
list of actual tests, which isn't nice if you're trying to capture and
parse this.
In commit 628effb369 we started verifying
the build.ninja file was up to date before even `--list`ing tests,
because we could end up with incorrect information. This meant that
ninja always runs at startup, and typically returns "no work to do",
which ended up listed as "one of" the tests.
Instead of unconditionally running ninja attached to the console, first
check it in dry-run mode with stdout intercepted, to see if ninja
considers itself up to date. If it is, continue. Only if an actual
refresh is needed, do we run it while attached to the console.
In the garden path, this avoids useless information. In cases where we'd
already print a full meson reconfigure log, we continue to do so.
By default, clang-cl based environments use rc.exe as resource
compiler. However, when cross compiling with clang-cl, one might
want to use llvm-rc instead.
Try to detect llvm-rc based on the output from "$CMD /?".
This requires a very recent llvm-rc; previosly, the output of
"/?" with llvm-rc was very generic and didn't explicitly indicate
that it actually was llvm-rc. This was changed in
bab6902eba
which will be included in the upcoming LLVM 17.0.0 release.
Contrary to the other regexes, don't include the preceding parts
of the line in the log printout, as it includes an unhelpful
"OVERVIEW:" prefix.
This fixes regression caused by
3162b901ca
that changes the order in which libraries are put on the link command.
In addition, that commit was wrong because libraries from dependencies
were processed before process_compiler() is called, which that commit
wanted to avoid.
When downloading wrap content, we need to know at some point if the
server is going to respond with "hello, yes, I'm here and I have data
for you". The alternative is to sometimes infinitely hang.
In commit 8f7781f1d6 we added such a
timeout, but using an extremely generously high number -- ten minutes.
We don't need to wait this long just to find out if the other end
exists, so decrease that time to 30 seconds, whch is still ludicrously
generous but not quite as much so.
This reverts commit 904b47085f.
This is not a real bottleneck, and we want to create it thrice -- once
before the backend is generated. The final install data needs to be
created fresh.
Update unittest to demonstrate the issue.

This has issues on Windows with msys2/cygwin, where we need to build it
ourselves since binary wheels aren't supported on PyPI. And we don't
have a rust compiler available for either one -- we may not be *able* to
do so for cygwin?
For msys2, the solution is pretty easy, just rely on the official msys2
packages for jsonschema, which handle both it and its dependencies for
us and don't require us to compile anything. Currently they still have
an older jsonschema that doesn't use rust deps at all, but that's
because the new jsonschema was released today. We'll automatically catch
up at some point.
For cygwin, there is no rust compiler in the cygwin repository, and
jsonschema there is old as the hills. I do not know if there's a good
answer here, but an adequate answer is to cap jsonschema at the version
we were testing with yesterday.
We need a union of the compilers used by the target, and by those used
by all dependencies, not all the compilers in all projects. We do,
however, need to look compilers up from all possible compilers, as a
dependency that is a subproject could use a language not present in the
current project.
