Keep separate counters for the ringbuffer and stream read/write
indexes.
The ringbuffer has 32 bits indexes while the pulse server is required
to keep 64 bit read/write indexes.
Also handle invalid seek flags.
Fixes#1331
This also brings the advantage that all tools, examples, modules, components
can also be compiled standalone out-of-tree using libpipewire from the system
When we don't have enough files to accept the connection, clear the
_IN flag so that we don't try to accept if over and over again.
When a client disconnects, set the flag again so that we try to
accecpt new connections again.
See #1305
Since !737 it is not required of modules to emit the "loaded"
event if they can load immediately, therefore remove the
unnecessary `module_emit_loaded()` call.
Furthermore remove redundant log messages as well.
Modules no longer need to emit the "loaded" event manually
if they can load immediately. In that case, the module loading
code will take care of emitting the event. If they can't,
they must return an async spa result, and emit the "loaded" event
when they see fit.
Fixes#1232
Just like the real free() we should just ignore a NULL pointer, makes the
caller code easier for those instances where properties are optional.
Patch generated with concinelle with a few manual fixes.
When the server or client goes away, detach the client
from the server to avoid potential use-after-free issues
that might occur if the client causes the
unloading of the server it is connected to.
E.g.:
pactl load-module module-protocol-native-tcp port=4713
pactl -s localhost:4713 unload-module module-native-protocol-tcp
See #1240.
If any of those two branches are taken, the connection
cannot make forward progress since no data will be read/sent
from/to the client.
For example, sending just 21 invalid bytes to the server
causes the first 20 bytes (client descriptor) to be read,
then rejected, leaving `client->message == NULL`. But since
polling is level triggered, `on_client_data()` and thus
`do_read()` will continue to be called ceaselessly,
thereby spamming the log and wasting resources.
Add support for listening on IPv6 addresses.
The following address formats are supported:
* tcp:[<ipv6-addr>]:<port>,
* tcp:<ipv4-addr>:<port>,
* tcp:<port>, and
* unix:<path>.
The IP addresses are parsed using `inet_pton()`,
only the formats supported by that function
are accepted.
The IPv6 address must be surrounded by square brackets,
they do not mean "optional" here. Specifying only the
port is equivalent to the following two addresses:
* [::]:<port>, and
* 0.0.0.0:<port>.
Address parsing has been made stricter: the port
must always be specified explicitly.
Fixes#1216.
