get_non_matching_default_options is checking a string from
project_default_options against a validated value from
coredata.options.
Passing the string to validate_value ensures that the comparison
is sound; otherwise, "false" might be compared against False
and a bogus difference is printed.
The way the tracking is currently done it works if no new subprojects
are added to a configured build directory. For cases where we want to
add a new subproject, it fails because we don't initialize builtins for
that subproject. This corrects that by checking to see if the subproject
already exists, and if it doesn't initializes the bultins for it.
Fixes: #8421
This is a) useless because it's only used to print which options are not
default, and b) harmful because it can result in cases where things
break, like in projects that set a standard that the chosen compiler
doesn't support, but the project (or some subset) can be built with a
different standard.
Fixes: #8360
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.
Following #7890, this patch introduces the ability to read the contents
of a file to the fs module.
This patch introduces the ability to read files at configure time, but
has some restrictions:
- binary files are not supported (I don't think this will prove a
problem, and if people are wanting to do something with binary
files, they should probably be shelling out to their own script).
- Only files outside the build directory allowed. This limitation
should prevent build loops.
Given that reading an arbitrary file at configure time can affect the
configuration in almost arbitrary ways, meson should force a reconfigure
when the given file changes. This is non-configurable, but this can
easily be changed with a future keyword argument.
This new keyword argument makes it possible to run specific
test setups only on a subset of the tests. For example, to
mark some tests as slow and avoid running them by default:
add_test_setup('quick', exclude_suites: ['slow'], is_default: true)
add_test_setup('slow')
It will then be possible to run the slow tests with either
`meson test --setup slow` or `meson test --suite slow`.
It is common, at least in GNOME projects, to have scripts that must be
run only in the final destination, to update system icon cache, etc.
Skipping them from Meson ensures we can properly log that they have not
been run instead of relying on such scripts to to it (they don't
always).
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
Currently InstallDir is part of the interpreter, and is an Interpreter
object, which is then put in the Build object. This is a layering
violation, the interperter should have a Holder for build data. This
patch fixes that.
aligning along the left is, I think, what most projects want to do.
Aligning along the middle looks subjectively ugly, and objectively
prevents me from further indenting an element, e.g.
Build information:
prefix : /usr
sysconfdir : /etc
conf file : /etc/myprogram.conf
A sub-subproject can be configured directly from
`subprojects/foo/subprojects/bar/` in the case `bar` is in the same git
repository as `foo` and not downloaded separately into the main
project's `subprojects/`. In that case the nested subproject violation
code was wrong because it is allowed to have more than one "subprojects"
in path (was not possible before Meson 0.56.0).
Example:
- self.environment.source_dir = '/home/user/myproject'
- self.root_subdir = 'subprojects/foo/subprojects/bar'
- project_root = '/home/user/myproject/subprojects/foo/subprojects/bar'
- norm = '/home/user/myproject/subprojects/foo/subprojects/bar/file.c'
We want `norm` path to have `project_root` in its parents and not have
`project_root / 'subprojects'` in its parents. In that case we are sure
`file.c` is within `bar` subproject.
Rust has it's own built in unit test format, which is invoked by
compiling a rust executable with the `--test` flag to rustc. The tests
are then run by simply invoking that binary. They output a custom test
format, which this patch adds parsing support for. This means that we
can report each subtest in the junit we generate correctly, which should
be helpful for orchestration systems like gitlab and jenkins which can
parse junit XML.
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).
I would have prefered to do these seperatately, but they are combined in
some cases, so it was much easier to convert them together.
this eliminates the builtins_per_machine dict, as it's duplicated with
the OptionKey's machine parameter.
This was all layering violations before. Now we have Headers in the
build module, and a holder in the interpreter. All of the type
validation is done in interpreter method for `install_headers`.
This fix a regression introduced in Meson 0.56.0 when using python 3.5.
Also mention in documentation that using a meson dict does not guarantee
ordering.
Fixes: #8074.
Allow methods on the compiler object to receive internal dependencies,
as long as they only specify compiler/linker arguments or other
dependencies that satisfy the same requirements.
This is useful if you're using internal dependencies to add special
"-D" flags such as -DNCURSES_WIDECHAR, -D_XOPEN_SOURCE_EXTENDED or
-DGLIB_STATIC_COMPILATION.
Some CMake packages fail to find at all if no version is specified.
This commit adds a cmake_version parameter to dependency() to allow you
to specify the requested version.
The only way to add it via warning_level is top opt in to -Wextra too.
But this is often not really desirable, since -Wextra is not stable --
it changes its meaning every compiler release, thus mysteriously adding
new warnings. Furthermore, it's not really the same kind of warning -- a
pedantic warning is always correct that your code is wrong, but defines
wrongness as "not per the portable standard". Unlike -Wextra it doesn't
try to judge your code to see if you're doing something that is "often
not what you meant", but is prone to false positives.
Really, we need different *kinds* of warning levels, possibly as an
array -- not just a monotonically increasing number. But since there's
currently nothing flexible enough to specify -Wpedantic without -Wextra,
we will just remove the warning for the former, and let people add it to
their project arguments in peace.
Right now sub-sub projects are not correctly registered, because we
don't have a way to pass up past the first level of subproject. This
patch changes that by making the build_Def_files as defined in the
Interpreter initializer accurate for translated dependencies, ie, cmake
dependencies won't define a dependency on a non-existent meson.build.
This means that it can always add the subi.build_def_files because they
are always accurate.
The deprecation message for "gui_app" is appearing for every target
rather than just once, and even if the required version is older
than 0.56.0. Use @FeatureDeprecatedKwargs to fix both issues.
