For SPA libraries that we link against elsewhere in the tree, declare a
declare a dependency "foo_dep" for that library that specifies how to
link to it. Then use that dependency in the various targets.
This removes the knowledge of how to link with the library from the
target which can treat it as just another dependency.
In the case of optional libraries (e.g. the journal support lib) we can
then use declare_dependency() to declare an empty dependencies and thus
link them unconditionally in the target.
If we don't have the capability to ptrace, we are probably running inside a
container, not the debugger. Check this first so we don't disable forking
mode.
Make this conditional on libcap - where libcap is not available always assume
we *do not* have a debugger attached. This is easier than telling everyone who
runs the tests in a confined system to install libcap.
Fixes#1285
Move the spa tests to the pwtest framework. The pod tests have only been
wrapped in the function callers, they don't use the variuos pwtest helpers -
too much work for very little gain here. Can be done incrementally if needed.
Note that this removes the spa tests from the installed tests. Arguably,
installing those tests was unnecessary anyway since they are static binaries
and don't load anything. So having them installed runs the same tests as
having them run in the source tree.
Goal for the pwtest framework is to allow for installed tests, just not there
yet.
Helper function to load a SPA interface. This enables a test to easily load a
specific interface and run tests against that interface without having to
instantiate a whole pipewire daemon.
Heavily inspired by libinput's litest framework (built around check), this is
a from-scratch framework that simplifies adding tests for various parts of
pipewire. See the pwtest.h documentation for details but the basics are:
- PW_TEST() and PWTEST_SUITE() specify the tests to be run
- Test are run in forked processes, any errors/signals are caught and printed
to the log
- Tests have a custom pipewire daemon started on demand to talk to [1]. The
daemon's log is available in the test output.
- Output is YAML to be processed into whatever format needed
[1] There are limits here, since we can't emulate devices yet there is only
so much we can rely on with the daemon.
