When setup creates a Visual Studio environment, a message is logged
which contains a path to the build directory. Typically, this path is
converted to a relative path prior to printing. If the path cannot be
converted to a relative path (e.g., because buildpath is on a different
drive from the cwd), print out the full path instead of failing with an
unhandled exception.
This will always be wrong, because when a directory component is
provided we need to match an exact filename on a manual search path, for
example find_program with dirs: or the current meson.build subdir.
If we ever get this far, shutil.which will do the same "is there a
dirname, if so just check whether the filename exists relative to
cwd"... except that the documented meson lookup path is that we check
relative to meson.build subdir, not relative to the cwd, and the cwd
could be anything, but is probably the root sourcedir.
Since internally, meson does not actually os.chdir into the sourcedir,
it could be absolutely anything at all, though.
...
The actual returned name for shutil.which(name) given a literal pathname
with a directory component is "return name" without adding the absolute
path, which means that this is double-broken. Not only does it find
things we didn't expect, the resulting ExternalProgram object doesn't
have the correct path to the program, so it will report "found" and then
fail to actually run when the current directory is changed, for example
by ninja -C.

This removes the warning when using default_options without fallback
kwarg completely because a subproject does not know if the main project
has an implicit fallback or not, so it could set default_options even if
not fallback is available at all.
Fixes: #9278
Since we changed to using a json file to avoid over long command lines
we created a situation where the generated files may not be ready when
the depscan happens. To avoid that, we need to add all of the generated
sources as order deps.
Fixes: #9258
This command is useful to e.g. update a cloned subproject which does not
have its packagefiles merged, or which has updated packagefiles. This
does not strictly require internet, so if we can satisfy the ref, simply
log a warning and continue.
This enables a workflow where for network-isolated builds, the
subproject is cloned and moved into place and later on the build
orchestrator runs `meson subprojects update` without a network interface
to initialize the subproject.
Since it cannot resolve `import typing as T` in order to figure out that
T.* is doing annotation-worthy stuff.
Since T.cast('Foo') is not actually using Foo except in an annotation
context (due to being a string) it requires extra work to resolve, and
the only thing that would currently work is actually using
'typing.cast'. However, we have decided to not use it except as T...
Since this import is only imported during mypy it's not so bad to noqa
it.
It is imported from a subpackage in __init__ alongside a big list of
other things which are all exported. And elsewhere, this import is
re-imported by other code. It's pretty clearly an oversight that it
didn't get added to __all__
Alias commands did not work with the vs backend, due to trying to access
target.command[0] with an empty command. Fix this by just not emitting a
CustomBuild node for alias targets - the project references are enough to
trigger the necessary actions.
Fixes: #9247
It's broken in various circumstances, no one seems to actually use it,
CI doesn't test it, no one is committed to maintaining it, etc. etc.
etc.
Also, projects doing trivially reasonable things, such as generating
"foo/util.py" and "bar/util.py", create clashing output names. This will
never, ever, ever, ever work with layout=flat.

Until we invoke interpreter.Interpreter(b, ...) the coredata options
still have their default values and thus cannot be used sensibly.
Currently the warning never shows (other than, unsurprising in
retrospect, during --internal regenerate).
In commit 3c4c7d0429 the qresource
variable stopped being overwritten with a mesonlib.File, which is
reasonable. However, one call site for it which relied on being a built
file did not get renamed when needed.
Make the build target use the built file.
The clang compiler now reimplements and re-checks the c_std and cpp_std
options in order to use them for objc as well, but it didn't
consistently support the same options. First it completely excluded all
the gnu ones, and then it added a handful of them but not for C++.
Be fully consistent -- or at least as consistent as we can be, given a
minimally working fix. (The C/C++ compiler mixin actually gates
different stds depending on detected clang version, we do not do that
here.)

Dependencies are currently printed as
[<mesonbuild.mlog.AnsiDecorator object at 0x7faa85aeac70>, ' ', <mesonbuild.mlog.AnsiDecorator object at 0x7faa85aeab50>]
This was introduced in commit adb1b2f3f6, due to
an incorrect type annotation on the AnsiText constructor. Fix both the
annotation and the usage.

Fixes various inconsistencies:
- gitattributes is respected
- export-subst
- export-ignore
- submodules with relative paths are not checked out relative to the
local clone (which does not work anyway)
- no need to manually remove gitfiles with inaccurate heuristics

"ERROR: Git program not found" is both highly true, and somewhat
inscrutable. Sure, looking at the line number you can basically figure
out that subproject('something') must somehow need git to operate, but
that may not be immediately obvious.
Make mention of the fact that it is needed to "download foo.wrap".
Fixes#7764
It is a commonly needed information to help debugging build issues. We
already were printing options with non-default value at the end of the
configure but outside of the summary.
Keeping the list of user defined options in the interpreter will also in
the future be useful to use new default value on reconfigure.
And more accurate too, TBH. Currently it says it is building "lang.mo",
even though it is actually building "domain.mo" inside
lang/LC_MESSAGES/.
Since meson loudly complains if I try to name the display name
"lang/domain.mo", name it with a dash instead of a slash. The actual
name isn't a priority here IMO, and this is nicely readable.
* compilers: improve docstring to `get_compiler_check_args()`
There was an incomplete list, which wasn't useful as it now takes an
enum anyway. Also add a new entry to the list of reasons to use this
function.
* clang: Add -Werror=implicit-function-declarations to check_args
Unlike GCC, clang warns but doesn't error when an implicit function
declaration happens. This means in checks like
`compiler.has_header_symbol('string.h', 'strlcat')` (on Linux, at least)
that GCC will fail, as there is no such function; clang will emit a
warning, but since it exists with a 0 status Meson interprets that as
success. To fix this, add `-Werror=implicit-function-declarations` to
clang's check arguments.
There seems to be something specific about functions that _may_ exist in
a header on a given system, as `cc.has_header_symbol('string.h',
'foobar')` will return false with clang, but `strlcat` will return true,
even though it's not defined. It is however, defined in some OSes, like
Solaris and the BSDs.
Fixes#9140
Removed in commit 487d45c1e5 but perhaps
it should not have -- people may have been depending on ensuring those
are built somehow. Even though the internal implementation changed and
it is now built by the all target, let's keep the old target around too.
Now it just aliases the actual build rules, though.
Users may wish to make use of these files for their own purposes.
For example, the -pot and -update-po pseudo targets could be reused in
an alias_target(), and at least one person wanted to reuse the built .mo
files as custom_target input.
