When a dependency is copied and its name is changed, we still need a way
to say "this is the same dependency", which we now have. It is
important, however, when a partial dependency is created that dependency
does *not* match the original dependency, since they are not providing
the same data. This was always happening for InternalDependencies as an
implementation detail, but not for other kinds.
These errors can make reading comments and documentation
unnecessarily confusing for users and contributors who
do not speak English as their first language.
Revert "interpreter: when overriding a dependency make its name match"
This reverts commit b1340e9bb1.
Revert "dependency: define equality and hash operators for Dependency"
This reverts commit 6d713e40f8.
This caused some projects to fail to build, such as libplacebo and
libepoxy. Taking libplacebo as the example, the produced build.ninja
does not include libvulkan.so as a linker input for
src/libplacebo.so.338.
We are probably getting dependency hashing wrong somewhere. Unsure where
exactly and unsure how to create a test case. We are also deep into rc2.
Revert it for now and try to re-land these changes for 1.6.
Bug: https://bugs.gentoo.org/935443Fixes: #13352
This replaces all of the Apache blurbs at the start of each file with an
`# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing
uses to be consistent in capitalization, and to be placed above any
copyright notices.
This removes nearly 3000 lines of boilerplate from the project (only
python files), which no developer cares to look at.
SPDX is in common use, particularly in the Linux kernel, and is the
recommended format for Meson's own `project(license: )` field
This also makes it more consistent with get_pkgconfig_variable() which
always return empty value instead of failing when the variable does not
exist. Linking that to self.required makes no sense and was never
documented any way.
Performed using https://github.com/ilevkivskyi/com2ann
This has no actual effect on the codebase as type checkers (still)
support both and negligible effect on runtime performance since
__future__ annotations ameliorates that. Technically, the bytecode would
be bigger for non function-local annotations, of which we have many
either way.
So if it doesn't really matter, why do a large-scale refactor? Simple:
because people keep wanting to, but it's getting nickle-and-dimed. If
we're going to do this we might as well do it consistently in one shot,
using tooling that guarantees repeatability and correctness.
Repeat with:
```
com2ann mesonbuild/
```
This will help with the writing of tools to generate
VisualStudio project and solution files, and possibly
for other IDEs as well.
- Used compilers a about `host`, `build` and `target` machines
arere listed in `intro-compilers.json`
- Informations lister in `intro-machines.json`
- `intro-dependencies.json` now includes internal dependencies,
and relations between dependencies.
- `intro-targets.json` now includes dependencies, `vs_module_defs`,
`win_subsystem`, and linker parameters.
Which adds the `use-set-for-membership` check. It's generally faster in
python to use a set with the `in` keyword, because it's a hash check
instead of a linear walk, this is especially true with strings, where
it's actually O(n^2), one loop over the container, and an inner loop of
the strings (as string comparison works by checking that `a[n] == b[n]`,
in a loop).
Also, I'm tired of complaining about this in reviews, let the tools do
it for me :)
Add a MissingCompiler class returned by compiler detecting methods
intead of None - accessing such an object raises a DependencyException
Fixes#10586
Co-authored-by: duckflyer <duckflyer@gmail.com>
In the debug logs, always log if a dependency lookup raises a
DependencyException. In the `required: false` case, this information
would otherwise disappear forever, and we would just not even log that
we tried it -- it doesn't appear in "(tried x, y and z)".
In the `required: true` case, we would re-raise the first exception if
it failed to be detected. Update the raise message with the same
information we print to the debug logs, indicating which dependency and
which method was used in the failing attempt.
- `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
By default, meson will try to look for shared libraries first before
static ones. In the meson.build itself, one can use the static keyword
to control if a static library will be tried first but there's no simple
way for an end user performing a build to switch back and forth at will.
Let's cover this usecase by adding an option that allows a user to
specify if they want dependency lookups to try static or shared
libraries first. The writer of the meson.build can manually specify the
static keyword where appropriate which will override the value of this
option.
This function can be used to add fundamental dependencies such as glib
to all build products in one fell swoop. This can be useful whenever,
due to a project's coding conventions, it is not really possible to
compile any source file without including the dependency.

Extract to a separate function the code that resolves dependencies
for compiler methods. We will reuse it for add_project_dependencies().

dep.get_variable() only supports string values for pkg-config and
config-tool, because those interfaces use text communication, and
internal variables (from declare_dependency) operate the same way.
CMake had an oddity, where get_variable doesn't document that it allows
list values but apparently it miiiiiight work? Actually getting that
kind of result would be dangerously inconsistent though. Also, CMake
does not support lists so it's a lie. Strings that are *treated* as
lists with `;` splitting don't count...
We could do two things here:
- raise an error
- treat it as a string and return a string
It's not clear what the use case of get_variable() on a maybe-list is,
and should probably be a hard error. But that's controversial, so
instead we just return the original `;`-delimited string. It is probably
the wrong thing, but users are welcome to cope with that somehow on
their own.
It would be too difficult and probably a layering violation to give an
interpreter handle to the inner guts of every dependency. What we can do
instead is let every dependency track:
- the Feature checks it can produce,
- the version attribute for when it was implemented
while leaving the interpreter in charge of actually emitting them.
We currently cannot make this work because inside dependency() we don't
know the current subproject. We would also like the optional but
extremely useful location node, but we don't have that either...
Convert the broken code to a FIXME for visibility.
This is a layering violation, we're relying on the way the interpreter
handles keyword arguments. Instead, pass them as free variables,
destructuring in the interpreter
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.
Dependencies are currently printed as
[<mesonbuild.mlog.AnsiDecorator object at 0x7faa85aeac70>, ' ', <mesonbuild.mlog.AnsiDecorator object at 0x7faa85aeab50>]
This was introduced in commit adb1b2f3f6, due to
an incorrect type annotation on the AnsiText constructor. Fix both the
annotation and the usage.

GTestDependencySystem (and other similar dep classes) sets
self.is_found=True, but the version check could still fail. In the case
the dependency is not required `ExternalDependency._check_version()`
won't raise an exception and thus the dependency is accepted.
_check_version() sets self.is_found() in the case self.version is not
empty, we should do it too when self.version is empty.
Fixes: #9036.
Just like we automatically provide some reusable glue for self.static,
provide it here too. It seems plausibly like something people would
commonly want.
Both of these are artifacts of the time before Dependency Factories,
when a dependency that could be discovered multiple ways did ugly stuff
like finding a specific dependency, then replacing it's own attributes
with that dependency's attributes. We don't have cases of that left in
the tree, so let's get rid of this code too
This commit introduces a new type of `HoldableObject`: The
`SecondLevelHolder`. The primary purpose of this class is
to handle cases where two (or more) `HoldableObject`s are
stored at the same time (with one default object). The
best (and currently only) example here is the `BothLibraries`
class.
