Meson was passing only the first output and warning about it. To do this
easily, refactor construct_target_rel_path to return a list.

For libraries installed to libdir, it's not expected to have rpath
hooked up. But for non-default libdirs, the path might not get searched
by default. `ldconfig -m <libdir>` is convenient here, as it will
programmatically add a new directory to search for shared libraries, so
the resulting installed programs work out of the box.
Include the dragonfly BSD platform name, which doesn't match the 'bsd'
catch-all pattern.
This previously worked because we were accidentally doing this via
mutation. However, doing this via mutation is not a good way to do it,
we should be explicit.

This replaces the absolute hack of using
```
install_subdir('nonexisting', install_dir: 'share')
```
which requires you to make sure you don't accidentally or deliberately
have a completely different directory with the same name in your source
tree that is full of files you don't want installed. It also avoids
splitting the name in two and listing them in the wrong order.
You can also set the install mode of each directory component by listing
them one at a time in order, and in fact create nested structures at
all.

This really is more of a struct than a dict, as the types are disjoint
and they are internally handled, (ie, not from user input). This cleans
some things up, in addition I spotted a bug in the ModuleState where the
dict with the version and license is passed to a field that expects just
the version string.
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.
* backends: Add a Visual Studio 2013 backend
This is more-or-less a quick port from the VS2015 backend, except that
we update the Visual Studio version strings and toolset versions
accordingly. Also correct the generator string for Visual Studio 2015
in mesonbuild/cmake/common.py.
* backend: Add VS2012 backend
Similar to what we did for Visual Studio 2013, add a Visual Studio 2012
backend.
* vs2010backend.py: Implement `link_whole:` if needed
We actually need Visual Studio 2015 Update 2 to use `/WHOLEARCHIVE:`,
which is what we are currently using for `link_whole:` on Visual Studio.
For Visual Studio versions before that, we need to expand from the
static targets that were indicated by `link_whole:`, and any of the
sub-dependent targets that were pulled in via the dependent target's
`link_whole:`. This wil ensure `link_whole:` would actually work in
such cases.
* vs2010backend.py: Handle objects from generated sources
Unforunately, we can't use backends.determine_ext_objs() reliably, as
the Visual Studio backends handle this differently.
* vs2010backend.py: Fix generating VS2010 projects
Visual Studio 2010 (at least the Express Edition) does not set the envvar
%VisualStudioVersion% in its command prompt, so fix generating VS2010
projects by taking account into this, so that we can determine the location
of vcvarsall.bat correctly.
* whole archive test: Disable on vs2012/2013 backends too
The Visual Studio 2012/2013 IDE has problems handling the items that would be
generated from this test case, so skip this test when using
--backend=vs[2012|2013]. This test does work for the Ninja backend when
VS2012 or VS2013 is used, though.
Consolidate this error message with XCode along with the vs2010 backend.
* docs: Add the new vs2012 and vs2013 backends
Let people know that we have backends for vs2012 and 2013. Also let
people know that generating Visual Studio 2010 projects have been fixed
and the pre-vs2015 backends now handle the `link_whole:` project option.
There's no reason to allow None into the backend, it already has code to
check that all of the values of the FileMode object are None, so let's
use that, which is much simpler all the way down.
When mutable items are stored in an lru cache, changing the returned
items changes the cached items as well. Therefore we want to ensure that
we're not mutating them. Using the ImmutableListProtocol allows mypy to
find mutations and reject them. This doesn't solve the problem of
mutable values inside the values, so you could have to do things like:
```python
ImmutableListProtocol[ImmutableListProtocol[str]]
```
or equally hacky. It can also be used for input types and acts a bit
like C's const:
```python
def foo(arg: ImmutableListProtocol[str]) -> T.List[str]:
arg[1] = 'foo' # works while running, but mypy errors
```
Dependencies is already a large and complicated package without adding
programs to the list. This also allows us to untangle a bit of spaghetti
that we have.
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
Rather than having to manually build the locale aware man paths with
`install_data('foo.fr.1', install_dir: join_paths(get_option('mandir'), 'fr', 'man1'), rename: 'foo.1')`
Support doing
`install_man('foo.fr.1', locale: 'fr')`
By default all subprojects are installed. If --skip-subprojects is given
with no value only the main project is installed. If --skip-subprojects
is given with a value, it should be a coma separated list of subprojects
to skip and all others will be installed.
Fixes: #2550.
run_target() does some variable substitutions since 0.57.0. This is a
new behavior, and undocumented, caused by sharing more code with
custom_target(). More consistency is better, so document it now.
custom_target() was doing variable substitution in the past, because it
shared some code with generator(), but that was undocumented. Some
refactoring in 0.57.0 caused it to not replace @CURRENT_SOURCE_DIR@,
@SOURCE_DIR@, and @BUILD_DIR@ anymore. This patch adds back
@CURRENT_SOURCE_DIR@ and document it. It does not add back @SOURCE_DIR@
because it is duplicate with @SOURCE_ROOT@ that has a better name. Also
do not add back @BUILD_DIR@ which is duplicate of @PRIVATE_DIR@, and
not @BUILD_ROOT@ surprisingly, adding to the confusion.
Even if the command is not wrapped by meson, it could have been modified
to add java/mono interpreters. This fix potential inconsistency between
wrapped and unwrapped commands.
Our approach to unity builds with vala is broken, you cannot unify the
generated C files, as they contain duplicate symbols. We would need to
instead combine the files while they are still in their vala form, then
convert that to C and compile the unified C file.
This does not fix the linked issue, as this removed the ability to do
vala unity builds, but it does allow running vala with `--unity=on`.

Replacements are already done by eval_custom_target_command() and must
be done BEFORE calling as_meson_exe_cmdline() anyway. replace_paths() is
still used by generators.
Make eval_custom_target_command() more readable by handling error in the
final else case instead of in the middle of elif.
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.
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
The /ZI flag adds in "Edit and Continue" debug information, which will
cause massive slowdown. It is not a flag that we should be adding by
default to debug builds.
/Zi will still be added.
This adds enough type annotations for InstallData and friends to make
minstall happy. There is also a small change in that I've replaced the
List[List] with List[Tuple], as tuples are more appropraite data types
for the information (fixed length, position matters, different types at
different indexes)
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.
If static_library is used as a convenience library (e.g. for link_whole)
it should in principle not need position independent code.
However, if the executables that the libraries is linked to are PIE,
the non-PIC objects in the static library will cause linker errors.
To avoid this, obey b_pie for static libraries if either b_staticpic=false
or they use "pic: false".
Without this patch, QEMU cannot use b_staticpic, which causes a slowdown
on some QEMU benchmarks up to 20%.
- Fixed using debug and optimization built-in options in MSVC.
- Fixed that VS backend does not create pdb files in release mode.
VS implicitly adds the debug fields if left out.
- Fix that it is possible to add debug info with ninja backend with
optimizations.
I've always found ninja reporting 'a meson_exe.py custom command'
unclear and confusing. Instead say we are invoking a custom command,
wrapped by meson, and why.
This reverts commit 8ee1c9a07a.
No rationale was given for this change prior to merging. After the fact
it was described as desired by distro packagers, however as a distro
packager I believe this commit hurts me.
From a distro packaging perspective, we primarily care about one thing:
previously building code should still build. Hence, -Werror is bad for
our use case. meson handles this via -D werror which is different from
-D warning_level and as long as the former is disabled, warnings in the
build do not cause harm (but may attract review attention for upstream
to fix).
buildtype is a completely unrelated concern, and the intention for
=plain is to disable debug or optimization settings that result in
codegen differences and thus different built artifacts. This must not
happen in distro builds because the *distributed programs* should
conform to policy settings.
Unfortunately, completely disabling warnings happens silently, and
cannot be overridden even if you really, really believe you know what
you're doing. It is thematically broken, since use of
add_project_arguments() to add more -W flags is not likewise ignored.
But if you try to add -Wall in that manner, meson will lecture you to
use warning_level which you cannot do. And if you have custom warning
flags which depend on options enabled by judicious use of -Wall via
default_options: 'warning_level=1', then you end up with generated
warnings complaining about your command line rather than your code, such
as:
cc1: warning: ‘-Wformat-y2k’ ignored without ‘-Wformat’ [-Wformat-y2k]
cc1: warning: ‘-Wformat-extra-args’ ignored without ‘-Wformat’ [-Wformat-extra-args]
cc1: warning: ‘-Wformat-zero-length’ ignored without ‘-Wformat’ [-Wformat-zero-length]
cc1: warning: ‘-Wformat-contains-nul’ ignored without ‘-Wformat’ [-Wformat-contains-nul]
cc1: warning: ‘-Wformat-security’ ignored without ‘-Wformat’ [-Wformat-security]
which then break the build with -Werror.
Throughout all this, a buildtype of "plain" does *not* disable -D
werror=true, which is the part where distro builds actually break down!
Users who both wish to disable debug/optimization codegen, *and* disable
warning commentary, are encouraged to do so by doing both, not by doing
one and having the other be assumed.
