A backslash-escape of the last newline before a run of whitespace
leading to the indented string ending and function termination `)` does
not actually escape the entire line and make it do nothing. In fact what
it does is cause all that whitespace to be part of the preceding line,
and get printed.
Meanwhile the textwrap.dedent documentation states that lines with only
whitespace get normalized. When you *don't* mess with that final line,
dedent actually does the right thing and makes the output message end
with a single newline after the important text.
Android requires shared modules that use symbols from other shared
modules to be linked before they can be dlopen()ed in the correct
order. Not doing so leads to a missing symbol error:
https://github.com/android/ndk/issues/201
We need to always allow linking for this. Also add a soname, although
it's not confirmed that it's needed, and it doesn't really hurt if it
isn't needed.
Use a derived type when passing `subproject` around, so that mypy knows
it's actually a SubProject, not a str. This means that passing anything
other than a handle to the interpreter state's subproject attribute
becomes a type violation, specifically when the order of the *four*
different str arguments is typoed.
Because we don't want to pass the Interpreter kwargs into the build
layer. This turned out to be a mega commit, as there's really on elegant
way to make this change in an incremental way. On the nice side, mypy
made this change super easy, as nearly all of the calls to
`CustomTarget` are fully type checked!
It also turns out that we're not handling install_tags in custom_target
correctly, since we're not converting the boolean values into Optional
values!
In some cases, init variables that accept None as a sentinel and
immediately overwrite with [], are migrated to dataclass field
factories. \o/
Note: dataclasses by default cannot provide eq methods, as they then
become unhashable. In the future we may wish to opt into declaring them
frozen, instead/additionally.
When generating pkgconfig file for a library that links to an
uninstalled static library built by custom_target() Meson was crashing
when trying to access some attributes that does not exist on that class.
Also fix is_internal() implementation, it only really make sense on a
CustomTargetIndex or if CustomTarget has only a single output.
FeatureCheck always immediately sets extra_message to '' if it isn't
explicitly passed, so there is really no point in using None as a
sentinel that is never used.
Names used in init functions are sometimes pointlessly different from
the class instance attributes they are immediately assigned to. They
would make more sense if defined properly.
Emit a detailed deprecation warning that explains what to do instead.
Also add a unittest.
```
DEPRECATION: target prog links against shared module mymod, which is incorrect.
This will be an error in the future, so please use shared_library() for mymod instead.
If shared_module() was used for mymod because it has references to undefined symbols,
use shared_libary() with `override_options: ['b_lundef=false']` instead.
```
Fixes https://github.com/mesonbuild/meson/issues/9492
It works fine as-is with an empty list, and since that's easier to get
using our typed_kwargs, and thus is what we're passing, go ahead and
simplify the class to only take a list of strings.
It's supposed to emit an error message, but instead it did a traceback.
It used to be, if no install_dir was specified then it was simply not in
kwargs, but due to typed_kwargs it will now be there, but not have
viable contents, so the dict membership check got skipped.
Fixes#9522
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.
Fixes#1604
Properly fixes#2904
To be able to handle link_depends in backends that do not just operate on a
file basis like ninja, information about the targets, not just their output is
required.
All changes were created by running
"pyupgrade --py3-only"
and committing the results. Although this has been performed in the
past, newer versions of pyupgrade can automatically catch more
opportunities, notably list comprehensions can use generators instead,
in the following cases:
- unpacking into function arguments as function(*generator)
- unpacking into assignments of the form x, y = generator
- as the argument to some builtin functions such as min/max/sorted
Also catch a few creeping cases of new code added using older styles.
This does not convert the build side, or remove any of the checking it
does. We still need that for other callers of custom target. What we'll
do for those is add an internal interface that defaults things, then
we'll be able to have those callers do their own validation, and the
CustomTarget validation machinary can be removed.
Fixes#9096
In the comparison methods of Target. There are several problems with the
old implementation:
1. It's not idiomatic
2. It can match on things that It shouldn't (like a Compiler, which has
a `get_id() -> str` method, but not one that we should compare with
Targets
3. It confuses mypy, which doesn't handle hasattr
