Most feature checks already use #ifdef, and do not care about
the value of the macro. Convert all feature checks to do that,
and simplify the meson build scripts by replacing
if cond
cdata.set('X', 1)
endif
with
cdata.set('X', cond)
This is more complicated than a normal module because we have two
logging topics: mod.protocol-native and conn.protocol-native for wire
messages. Because the latter use spa_debug (through spa_debug_pod) we
need to #define our way around so those too use the right topics.
Note that this removes the previous "connection" category, it is now
"conn.protocol-native" instead.
Leaving sockets in the home directories is bad form, so let's not do
this.
This effectively requires XDG_RUNTIME_DIR to be set for pipewire to
work - it is set correctly on most setups anyway and on custom setups
this needs to be addressed with a custom environment.
Fixes#1443
This also brings the advantage that all tools, examples, modules, components
can also be compiled standalone out-of-tree using libpipewire from the system
Do not return an error immediately if connect() fails with EAGAIN. Check
if it completed successfully with getsockopt() when the socket becomes
writable instead.
This is the way to handle non-blocking connect() by the book but after
testing it seems that the case when connect() fails with EAGAIN is when
the listen backlog is full on the server side and in that case the
server socket is closed. So even though connect() completes successfully
according to getsockopt() the client socket is no longer usable
(on_remote_data() will get both SPA_IO_OUT and SPA_IO_HUP in mask on the
first call after connect() returned EAGAIN).
If buffer type char[] is 4-byte aligned, higher 3-byte on char could be non-zero if data is not initialized, which make 'buffer[i] >> 4' larger than 0x0f.
Use type uint8_t[] on SEC_LABEL buffer to fix it.
The message structures returned by pw_protocol_native_connection_get_next
point to data that is contained in the buffer of the connection.
The data was invalidated when pw_protocol_native_connection_get_next was
called the next time, which made the connection loop non-reentrant, in
cases where it was re-entered from demarshal callbacks.
Fix this by allocating new buffers when reentering and stashing the old
buffers onto a stack. The returned message structure is also stored on
the stack to make lifetimes to match.
If a client becomes unbusy again, signal a resume event so that the
messages are processed in the next mainloop iteration. This gives the
current iteration time to perform cleanups if needed.
Remove the look hook and always do flushing with an IO_OUT event. Rework
some things so that we can flush right after processing input without
having to go through a loop iteration.

This variable describes whether we have systemd and libsystemd,
not just <systemd/sd-daemon.h>
While at it, sneak in a fix for the warning message:
"systemd should never ever be capitalized".

Remove the hooks we installed on objects in the destroy/free event
or before calling _destroy. This is not really needed but it is
a nice thing to do because it calls the hook removed callbacks.
PIPEWIRE_CORE can be used to specify a server name.
PIPEWIRE_REMOTE can be used to specify what server name to
connect to.
Either use the absolute path of the name to create and connect
to a server, or use a relative path. For a relative path, the
server name will be completed by prefixing the following paths
in order:
PIPEWIRE_RUNTIME_DIR environment variable,
XDG_RUNTIME_DIR environment variable,
HOME environment variable,
USERPROFILE environment variable,
home directory as stored in the password database.
Fixes#259
First use the configured properties, then use the env variables.
Make the daemon use the env variable by default.
This makes it possible to start servers with PIPEWIRE_CORE env variable
names but still override with the command option.
Makes it possible to make apps connect to PIPEWIRE_REMOTE env by
default and allows you to override with the command option.
Send create_object error messages to the new resource id so that
the client can better know what proxy is failing.
Use resource_remove when create_object fails because the core will
already send a remove_id on failure.
Try to send other errors to the proxy that made the request if
possible.
Log an error when we send an error to the client so that we don't need
to log and error anymore.
Improve the error messages when we can

The socket call does not terminate the string with '\0' so

Make it possible to pause emision of events from the core object.
This is interesting if we need to wait for completion of some operations
on another connection before resuming processing.
