We have a lot of these. Some of them are harmless, if unidiomatic, such
as `if (condition)`, others are potentially dangerous `assert(...)`, as
`assert(condtion)` works as expected, but `assert(condition, message)`
will result in an assertion that never triggers, as what you're actually
asserting is `bool(tuple[2])`, which will always be true.
Currently, we write each file to the command line, but this can result in
situations where the number of files passed exceeds OS imposed command
line limits. For compilers, we solve this with response files. For
depscan I've chosen to use a JSON list instead. JSON has several
advantages in that it's standardized, there's a built-in python module
for it, and it's familiar. I've also chosen to always use the JSON file
instead of having a heuristic to decide between JSON and not JSON,
while there may be a small performance trade off here, keeping the
implementation simple with only one path is wort it.
Fixes#9129
Don't just create a .PHONY target which runs a script that magically
generates files ninja doesn't know about. It results in untracked files,
and `meson install` has to run additional commands instead of copying
over files, and then cannot track them to uninstall them later.
I'm not even really sure why it was originally done via a proxy script,
most likely bad legacy design. This is after all one of the oldest
modules...
One side effect of this is that meson doesn't know how to rename
build.CustomTarget files on install (only data files are supported?),
and every file needs to be installed as "domainname.mo" so it must be
named that in-tree too. To prevent clashes, every locale gets its own
locale-specific subdirectory.
Once we are doing that anyway, we can output them to the actual
structure required by the gettext family of functions, and
bindtextdomain() can therefore point to this location if desired. This
might be useful for running localized programs from the build tree.
Sonarcloud.io only can read the sonarqube based report that gcovr can
produce. This change enables support for this output in meson and
ninja.

1. use `locale.getpreferredencoding()` to get encoding name.
`bytes.decode()` assumes `encoding='utf-8'` by default. It is incorrect on my
Windows setup, and causes `UnicodeDecodeError`.
2. use `errors='replace'`.
`bytes.decode()` assumes `errors='strict'` by default. Meson shouldn't crash
if subprocess outputs some garbage that can't be decoded.
`surrogateescape` doesn't work as expected on Windows. On Linux, default
`errors` for `sys.stdout` is `strict`, so `surrogateescape` can't be used there
too (at least until `sys.stdout` is reconfigured).

All changes were created by running
"pyupgrade --py3-only --keep-percent-format"
and committing the results. I have not touched string formatting for
now.
- use set literals
- simplify .format() parameter naming
- remove __future__
- remove default "r" mode for open()
- use OSError rather than compatibility aliases
- remove stray parentheses in function(generator) scopes
Re-implement it in backend using the same code path as for
custom_target(). This for example handle setting PATH on Windows when
command is an executable.
On Windows this would fail because of missing DLL:
```
mylib = library(...)
exe = executable(..., link_with: mylib)
meson.add_install_script(exe)
```
The reason is on Windows we cannot rely on rpath to find libraries from
build directory, they are searched in $PATH. We already have all that
mechanism in place for custom_target() using ExecutableSerialisation
class, so reuse it for install/dist/postconf scripts too.
This has bonus side effect to also use exe_wrapper for those scripts.
Fixes: #8187
In Fortran it is common to use capital F in the suffix (eg. '.F90') if
the source file makes use of preprocessor statements. Such files should
probably be treated like all other fortran files by meson.
Case insensitivity for suffixes was already implemented several places
in meson before this. So most likely, the few places changed here were
oversights anyway.
It's only used for doing an `if x in container` check, which will be
faster with a set, and the only caller already has a set, so avoid
we can avoid a type conversion as well.
This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
It turns out my first attempt to fix this in 00d5ef3191 ("Fix
clang-tidy return value reporting (#7949)") is not sufficient: The
local variable returncode is never updated and stays at 0. This fixes
the returncode calculation.
Fixes: cce172432b ("Use run-clang-tidy when available.")
* Fix clang-tidy return value reporting
In case clang-tidy is invoked manually, i.e. if run-clang-tidy(.py) is
not found, Meson would not report the return value. This is caused by
ignoring the return value of manual_clangformat() in clangformat()
within mesonbuild/scripts/clangtidy.py.
Even though only more recent-versions of clang-tidy actually report an
non-zero exit code if errors are found, there is no reason Meson
shouldn't simply report any error codes it received from clang-tidy.
Fixes#7948.
* Rename methods in clangtidy.py from clangformat to clangtidy
For some unknown reason, the method names in clangtidy.py are clangformat()
and manual_clangformat(). This is confusing, as clang-format is not
invoked by them, clang-tidy is. Hence rename those from
{manual_}clangformat() → {manual_}clangtidy()
`pathlib.Path.glob()` also returns directories that match source
filenames (i.e. a directory named `test.h/`), but `clang-format` and
`clang-tidy` fail when handed a directory. We manually skip calling
`clang-format` and `clang-tidy` on those directories.
