CT_OUTPUT_KW is the same OUTPUT_KW we use in lots of places. The most
distinctive thing about it is not that it's part of custom_target
(basically any other function that uses such a kwarg follows the same
rules due to using CustomTarget under the hood), but the fact that it
takes multiple outputs.
We validate a few things here, such as the non-presence of '@INPUT' in
an output name. These got moved out of the CustomTarget constructor in
commit 11f9638035 and into KwargInfo, but
only for kwargs that took multiple values. This caused configure_file()
and unstable_rust.bindgen() to stop checking for this.
Add a shared single-output KW and use it in both places. This now
dispatches to _output_validator.
configure_file now validates subdirectories in output names the same way
we do elsewhere, directly in the typed_kwargs and by specifying the
erroring kwarg.
Or any other reserved names. We check in add_target that the primary
name of any build target isn't on the forbidden list, but custom_target
allows names that are distinct from the output filenames, so we need to
check those too.
We would eventually still error out all the way at the end, with:
```
ERROR: Multiple producers for Ninja target "all". Please rename your targets.
```
But, if we can check that early and provide the underlying reason
(reserved name) alongside actually useful debugging info (a line
number), then why not?
Refactor the check into a small helper function in the process.
We don't want to allow targets that conflict with:
- our aliased meson-* targets for phony commands
- any meson-*/ directories we create for internal purposes
We do want to allow targets such as:
- our own meson-*.X manpages
There are a couple routes we could take.
Using a better restriction, such as `meson-internal__*`, is trivially
done for our aliased targets, but changing directory names is...
awkward. We probably cannot do this, and doing the former but not the
latter is not very useful.
We could also carefully allow patterns we know we won't use, such as
file extensions, but which the manpages need, which works for our
directories and for many aliased targets, but run_target() is
user-specified and can be anything.
Use a hybrid approach to cover both use cases. We will now allow target
names that fulfill *all* the following criteria:
- it begins with "meson-"
- it doesn't continue with "internal__"
- it has a file extension
Every phony target has a special indirection rule created because ninja
is bad at deleting generated outputs and tries to delete phony outputs
too.
Instead of invoking this as a separate helper post-creation function to
create the alias, wrap NinjaBuildElement and create it behind the
scenes. This simplifies target naming and means one less line at every
single use site.
The `install_headers` function now has an optional argument
`preserve_path` that allows installing multi-directory
headerfile structures that live alongside sourcecode with a
single command.
For example, the headerfile structure
headers = [
'one.h',
'two.h',
'alpha/one.h',
'alpha/two.h',
'alpha/three.h'
'beta/one.h'
]
can now be passed to `install_headers(headers, subdir: 'mylib', preserve_path: true)`
and the resulting directory tree will look like
{prefix}
└── include
└── mylib
├── alpha
│ ├── one.h
│ ├── two.h
│ └── three.h
├── beta
│ └── one.h
├── one.h
└── two.h
Fixes#3371
We have two checks for the type accepted here. One is the basic
typed_kwargs type-checking, which declares it accepts:
str | include_directories
The other is the custom validator which further narrows it to strings
with certain option-like properties (needs to be an = assignment).
The former is obviously wrong, which doesn't really matter all that much
but still isn't very nice...
Introduced in commit f34013fb08.
override_options makes no sense for custom_target as we don't use it for
anything. Also, this was added in commit c3c30d4b06
despite not being allowed in permittedKwargsc3c30d4b0.
For inexplicable reasons, we had a known_kwargs for custom_target that
looped over kwargs and issued a warning, not an error, for unknown
kwargs. It was impossible to ever hit that check to begin with, though,
ever since commit e08d735105 which added
permittedKwargs and obsoleted those manual checks with real errors.
So at one point override_options was specially permitted to be used
without emitting a warning, and then for about half a decade it was an
error, and then based on some dead code it was allowed again for a bit.
But through all this it doesn't do anything and isn't documented.
For maintainer targets, we need some more tools that gettext-tiny
doesn't implement. It's a shame to cause NLS to be completely disabled
in such environments, so instead just issue a warning and continue.
Before 0.62.0 these were never checked for, and would simply fail at
runtime, probably. In theory, the user might install the tools in
between configuring and building, and then the maintainer targets would
begin to work. Return to that behavior -- we still create the targets,
which will *probably* fail, but might not -- and for existing
integrations, failing at `ninja foo-update-po` with "error, program
msgmerge not found" is a bit more discoverable than ninja saying "what
do you mean, there's no such target".
We still have the 0.62.0 preferred behavior of trying to find the
programs, succeeding in all cases other than gettext-tiny, and
guaranteeing that their paths are set up in a machine-file-respecting
manner.
In the former case, the presence of tools is optional, but triggers a
warning and then no-ops the target. In the latter case, the presence of
the tools is mandatory. But if it was already looked up and discovered
to be missing, we did not actually check that it is found before trying
to use it.
In the case that it isn't found, check again, so that we explicitly
error out with a relevant error message due to setting the required
flag.
Fixes#10320
mingw GCC using ld.bfd emits diagnostics that include
"-plugin-opt=-pass-through=-lmoldname" and this triggers a match for
mold when it should not.
Instead, always check the very beginning of the output for the linker
id. This is pretty consistent:
- it is always on stdout
- GCC may put additional things on stderr we don't care about
- swift is bizarre and on some OSes redirects the linker stdout to
swiftc's stderr, but it will still be the only stderr; we didn't even
check stderr at all until commit 712cbe0568
For gold/bfd linkers, the linker id is always the *second* word, after
the legally mandated "GNU" we already check for.
We accept boolean false to indicate "do not install this one particular
output", but the type checking simply checked if it is a bool. We do
this correctly for configure_file, so copy the same validator from
there.
This fixes bogus messages "skipped: feature foo disabled" when
auto_features=disabled. It was reporting the name of the latest
get_option() call instead of the name of the current feature option.
This is especially visible in GStreamer summary where it should show a
different option name for every subproject but instead shows "tools"
everywhere:
```
Subprojects
gst-devtools : NO Feature 'tools' disabled
gst-editing-services : NO Feature 'tools' disabled
...
```
- `BuildTarget` should be `SharedLibrary | StaticLibrary`
- Needs to take `CustomTargetIndex` as well as `CustomTarget`
- don't assign to self until values have been converted to the correct
type
Change message
Header <foo.h> has symbol "BAR"
to
Header "foo.h" has symbol "BAR"
with the first part also now in bold. This is more consistent with
other messages like
Has header "foo.h"
and
Checking whether type "foo" has member "bar"
We were poking directly at the node, so if it was a FunctionNode then
this broke. Instead, just do a reverse lookup in the overrides table to
get the original find_program name.
TAP version 14 introduced subtests, that are supposedly backward compatible
because "TAP13 specifies that non-TAP output should be ignored". Meson
reported TAP syntax errors based on behavior of "prove" at the time,
but it seems that now "prove" has become a lot more lenient; it even
accepts the following completely bogus input just fine:
---
ok 1
ok 2
x
1..1
---
So do the same and make Meson's parser accept invalid TAP input silently.
Fixes: #10032
"targetting" is verb-derived adjective, which sort-of-works here, but
makes the whole sentence awkward, because there's no verb. Let's just
use present simple.
"tried to use" implies that the attempt was not successful, i.e. that meson
ignored the feature. But that is not what happens, apart from the warning the
feature works just fine. The new message is also shorter ;)
In commit 6acfe48f32, the kwarg was added
to environment() in addition to the env object methods. As part of the
associated refactor, a shared KwargInfo was used, and evolved to be new
since 0.62.0 in the two cases where it is in fact new.
However, it *also* set the base KwargInfo for the exact same newness,
which is wrong as it was present ever since the initial introduction in
0.34.0
As usual for anything that predates 0.37.0 we simply don't tag
FeatureNew. Revert this back to the same KwargInfo definition from
before the refactoring commit.
Fixes#10402
This was added in commit 01be50fdd9 with
zero explanation as a side effect of moving code around. It seems like a
really bad idea and it causes people to view debugging Meson projects on
e.g. debuginfod systems as "painful".
Previously, any value other than `windows` or `console` caused an
exception. This change allows for `efi_application` to be passed as
the `win_subsystem` to MinGW based linkers.
If we encounter a file under the Boost library directory that doesn't
look like a Boost library binary, we should ignore it.
We log a warning for each file we ignore, except for ones we know are
safe to ignore (e. g. PDB files from the SourceForge Windows
distribution). This should avoid polluting the log.
Fixes#8325.
python compiled extensions should never need to expose any symbol other
than PyInit_* which is declared with default visibility via
PyMODINIT_FUNC on supported compilers.
Thus, a reasonably sane default is to mark any other symbols as hidden,
while still respecting any manually specified visibility.
Gate this on the version of python itself, as not all versions decorate
PyMODINIT_FUNC properly.
This option is only valid for C++ and ObjC++, but the kwarg is useful
for mixed language targets. Asking for inlines as well, when the
compiler driver is trying to build the C components of a target, results
in gcc emitting:
```
cc1: warning: command-line option ‘-fvisibility-inlines-hidden’ is valid for C++/ObjC++ but not for C
```
Squelch this warning by filtering it out on Meson's side of things.
In commit fb2cdd0fe2 the internal property
was renamed, but one use case of it in raising a MesonException was not
changed to go with it.
This meant that instead of erroring out with:
```
ERROR: GNU symbol visibility arg XXXX not one of: default, internal, hidden, protected, inlineshidden
```
we instead errored out with:
```
AttributeError: 'SharedLibrary' object has no attribute 'symbol_visibility'
```
