Previously, valgrind was warning that
Syscall param sendmsg(msg.msg_iov[0]) points to uninitialised byte(s)
this was caused by uninitialized values being serialized for IPC.
Specifically, not all members of the `pw_endpoint_info` struct were
initialized, which caused uninitialized bytes to end up in the IPC
buffers due to the `pw_endpoint_emit_info()` in `endpoint_add_listener()`.
Fix that by initializing the missed `id` and `flags` members.
The PropInfo either has a registered id (and then also a name from the
type-info) or a custom name as a string.
In all cases, the description contains a free form text that clarifies
the property.
Use the description in the stream controls name.
This test currently prevents us from running the test suite in valgrind but
it's not a straightforward fix. So in the meantime, skip this test when
running under valgrind.
This also brings the advantage that all tools, examples, modules, components
can also be compiled standalone out-of-tree using libpipewire from the system
Clear the hook before adding it so that we are sure the removed
callback doesn't contain garbage and cause a crash on disconnect.
Mark the removed and priv fields as private. Make sure to add the
removed callback after adding the hook.
Fixes a crash in kwin
Make sure the hook lists are emptied so that the removed callbacks
are called. The callers should really remove the hook they installed
themselves but this is a last chance to fix things up.
This tests exporting a PW_TYPE_INTERFACE_Endpoint and binding
a proxy for it through the registry, verifying that info and params
are propagated properly from one to the other
