Instead of invoking javac for every .java file, pass all of the sources
for a jar target to a single javac invocation. This massively improves
first compilation time and doesn't meaningfully affect incremental builds
(it can even be faster in some cases).
The old approach also had issues where files would not always get recompiled
even though they should, necessitating a clean rebuild in order to see changes
reflected in the build output.
Multiple invocations seem to only make sense if:
- issues with files not getting flagged for rebuild are investigated and fixed
- something like the javaserver buildtool from openjdk sources is used
instead of directly spawning javac processes
- the amount of java files per jar is so large that it is faster to compile
several files one by one than to compile all the files at once (batching may
still make sense to get a reasonable balance)
Some settings require "objectVersion" to be set to a certain value or
Xcode will not use it. To fix this, we set it to the highest possible
value, determined by the detected version of Xcode. We also set
"compatibilityVersion", but mainly so it lines up with "objectVersion".
At the same time, we should not be generating Xcode 3.2-compatible
projects by default anyway.
C#, Java, and Swift targets were manually collecting compiler arguments
rather than using the helper function for this purpose. This caused each
target type to add arguments in a different order, and to forget to add
some arguments respectively:
C#: /nologo, -warnaserror
Java: warning level (-nowarn, -Xlint:all, -Xdoclint:all), debug arguments
(-g, -g:none), -Werror
Swift: -warnings-as-errors
Fix this. Also fix up some no-longer-unused argument processing in the
Compiler implementations.
The code would create a dictionary that was of type `str : list[str] |
str | None`. Then would later try to call `len(' '.join(dict[key]))`.
This would result in two different bugs:
1. If the value is `None` it would except, since None isn't iterable
and cannot be converted to a string
2. If the value was a string, then it would double the length of the
actual string and return that, by adding a space between each
character
When getting debug file arguments we can sometimes pass None, where a
None is unexpected. This becomes a particular problem in the Cuda
compiler, where the output will unconditionally be concatenated with a
static string, resulting in an uncaught exception. This is really easy
to spot once we annotate the functions in question, where a static type
checker like mypy easily spots the issue.
This commit adds those annotations, and then fixes the resulting error.
Fixes: #12997
There's a known ninja bug
(https://github.com/ninja-build/ninja/issues/1952) that running this
with dyndeps will result in Ninja deleting implicit outputs from the
dyndeps, leading to pointless rebuilds. For reference, this is what
CMake does as well.
We already have to decide whether to scan a file at configure time, so
we don't want to have to do it again at compile time, every time the
depscan rule is run. We can do this by saving and passing the language
to use in the pickle, so depscan doesn't have to re-calculate it. As an
added bonus, this removes an import from depscan
We don't need to write and pass two separate files to the depscanner,
I've used the pickle because the pickle serializer/deserializer should
be faster than JSON, thought I haven't tested.
We'll need it in a moment for get_base_compile_args -> get_assert_args.

Places where compiler needs it already have access to Environment object
and can use it directly.
This fixes mypy complaining that not all compilers have self.exe_wrapper
in run() method that got moved to base class.
When linking with a Rust rlib, we should also link with its external
system dependencies. This was currently done only for C ABI crates, do
it for both rlib and staticlib now.
Using scan-build gives the following warning:
"Running the setup command as `meson [options]` instead of
`meson setup [options]` is ambiguous and deprecated."
This commit fixes this issue by adding the setup keyword to the meson command.
The type of quoting was changed in 522392e to one that is suitable for
use with cmd.exe on Windows. However, the documentation states that the
type of quoting in MESONINTROSPECT is compatible with shlex.split() and
elsewhere in the code, the same variable is still quoted with
shlex.quote(). As mostly identified in #12148, there are a few choices:
1. Use shlex.quote() consistently and support Python but not cmd.exe.
2. Use join_args and support cmd.exe but not Python.
3. Use join_args and support splitting through the mesonbuild Python library.
This commit implements the first option and reverts part of 522392e.
Regression testing is implemented in #12115.
Fixes#12148
Xcode 14 has dropped the legacy build system, forcing us to use the
new one introduced in Xcode 9. The new system requires that we conform
to its "clean build folder" behavior, or clean operations fail.
CMake achieves this by setting other variables instead of SYMROOT, so
we follow that approach while retaining our current behavior as much
as possible.

Some backends may need to use its own target directories instead of
our default one. For this, introduce an optional argument "targetdir"
that will still use our default one when not specified.
Currently, the backend has "x86_64" hardcoded as the architecture,
which breaks cross compiling and compiling normally on arm64. Fix
this by setting it to the host machine's CPU architecture instead.
This patch adds 'depends' keyword to compiler.preprocess().
It allows to execute other targets before doing the preprocessing.
Test-case is added to demonstrate that functionality: it
generates the header before preprocessing the C source that
uses that generated header.
Thanks to @bruchar1 for getting this patch to work.
This change fixes two usability issues with the genvslite project
generation. Unlike when using the full VS backend, under genvslite the
ProjectName property wasn't being set for generated projects. This means
projects end up being named according to the project files, which
includes suffixes like "@exe" in the solution, which is undesirable.
This change adds the ProjectName field in for genvslite projects, to
keep the naming consistent with projects under the VS backend.
Additionally, previously under genvslite, no projects were set to build
under any solution configuration by default. This is inconvenient, as
the user has to manually edit the build settings for each solution
configuration before they can compile at the solution level. There was a
note in the code to do something about this. This change enables
compilation at the solution level for the default startup project in the
solution, so the user can now just press F5 to build the solution and
run the default startup project, as they would typically expect.
On Linux many .so's are augmented with version information,
e.g. libxyz.so.1.2.3. CMake will happily refer to these versioned .so's
in its dependencies instead of libxyz.so (typically a symlink).
Unfortunately these versioned .so's aren't recognized as libraries by
the Backend's logic to produce build rpaths from library paths.
Fix this by recognizing any .so extension as sufficient reason to
produce a build rpath, not just if .so is the last extension.
* Vala: depend on gresources
Valac uses gresource at compile time to look up .ui files
* Automatically pass `--gresourcesdir` to valac
* gnome.compile_resources: clean up duplicate paths better
* Add a test for improved gresouce handling
