Any code that needs to know mesonlib.python_command currently assumes
the PyInstaller bundle reference is added to the sys module, which means
that it assumes the only freeze tool used is PyInstaller. Really, all we
need to check is sys.frozen as it's never normally set, but always set
for a freeze. We don't care if it was PyInstaller specifically, and we
don't need its bundle directory.

Popen_safe_logged has a small inefficiency. It evaluates the stripped
version of stdout/stderr before checking if it exists, for logging
purposes. This would sometimes crash, if it was None instead of ''.
Fixes#12979
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
Allow macro_name to be speficied as a parameter to configure_file().
This allows C macro-style include guards to be added to
configure_file()'s output when a template file is not given. This change
simplifies the creation of configure files that define macros with
dynamic names and want the C-style include guards.
Coredata is where all option handling is done so it makes sense there.
It is a view on a list of options for a given subproject and with
optional overrides. This change prepare for using that view in a more
generic way in the future.

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.

- allow defines with leading whitespace
- always do replacement for cmakedefine
- output boolean value for cmakedefine01
- correct unittests for cmakedefine
- add cmakedefine specific unittests
meson tests enable PYTHONWARNDEFAULTENCODING by default and
make EncodingWarning fatal too.
Starting with Python 3.11 CPython not only warns if no encoding is passed
to open() but also to things like subprocess.check_output(). This made
the call in vsenv.py fail and in turn made test_vsenv_option fail.
check_output() here calls a .bat file which in turn calls vcvars. I don't
know what the encoding is supposed to be used there, so just be explicit
with the locale encoding to silence the warning.
This detects cases where module A imports a function from B, and C
imports that same function from A instead of B. It's not part of the API
contract of A, and causes innocent refactoring to break things.
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.

- 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.
This is useful for internal scripts that want to know about something
other than MESON_INSTALL_PREFIX and MESON_INSTALL_DESTDIR_PREFIX, which
is very specific to the prefix.
Checking the executable basename sort of works, at least for Windows,
since Windows always happens to use exactly this approach. However, the
official pyinstaller documentation suggests a very different approach:
https://pyinstaller.org/en/stable/runtime-information.html
This approach is more robust since it works on any OS, and in particular
it allows me to test the PyInstaller bundle functionality on Linux, even
though we don't officially distribute it as such.
We need to remember its value when reconfiguring, but the Build object
is not reused, only coredata is.
This also makes CLI more consistent by allowing `-Dvsenv=true` syntax.
Fixes: #11309
In commit 97a72a1c53 we started to allow
cmakedefine with 3 tokens, as cmake expects (unlike mesondefine). This
would silently start working even if the declared minimum version was
older than 0.54.1
It's actually Generic, and we should use Generic annotations to get the
correct result. This means that we don't have to assert or cast the
return type, because mypy just knowns
This can raise any OSError, but we only caught two of them that indicate
a particular failure case. Also catch the generic error form with a more
generic message.
This produces better error messages in cases where e.g. exclusive lock
is not supported.
We shouldn't be hardcoding library dirs anyway. And we usually get this
from the compiler.
This function has been unused since its users were moved to use the
compiler method, in the following commits:
- a1a4f66e6d
- a3856be1d5
- 08224dafcb
It is often more useful to generate shell script than dumping to stdout.
It is also important to be able to select the shell format.
Formats currently implemented:
- sh: Basic VAR=prepend_value:$VAR
- export: Same as 'sh', but also export VAR
- vscode: Same as 'sh', but without substitutions because they don't
seems to work. To be used in launch.json's envFile.
EnvironmentVariables was always broken, it used MutableMapping because
everyone <3 abstract interfaces, especially when they are broken and
don't actually do what you want.
This needs a dict interface, exposing `.copy()`. We either use a dict or
os._Environ, and the latter also supports that.
Also fix a broken import, and the fallout from forgetting to update the
signature of self.envvars in commit b926374205.
