Bug description:
[Description]
Systemd socket activation for Speech Dispatcher.
- Creates the speech-dispatcher.socket;
- Modifies the server so that it can detect it was automatically launched
by that socket activation; and
- Modifies the Autotools files accordingly.
[Impact]
It's relevance is described in [1], of which I quote the essential
parts [my notes in brackets]:
> Sandboxed applications [snaps] that use Speech Dispatcher currently bundle
it inside of the sandbox, so that each application has its own "private"
instance of Speech Dispatcher running. This works more or less, but it has the
downside that speech dispatcher cannot coordinate simultaneous messages from
multiple apps. When multiple sandboxed apps use Speech Dispatcher at the same
time, the text reading overlaps.
>
> In order to solve this issue, I would really like to give sandboxed apps
access to the Speech Dispatcher instance of the host.
That can be done by implementing the action of the speech dispatcher
service via a Systemd socket:
> The only issue I see is having it auto launch. I think it would
probably be a good step forward for speech-dispatcher to be auto
launched by a systemd socket like other daemons already do on demand.
That way the host speech-dispatcher with it's configuration would be
used by all snaps,
[Additional information]
The changes are already merged upstream[21][22][23], but still not
released.
I have built and installed the package in Mantic and verified that
running spd-say from inside a snap causes the host's dispatcher to
spawn and emit sound — see 'Test case' for more details. This has also
been verified in Jammy by Lissyx[31][32] and there is a merge
proposal[4] for the Firefox snap that assumes the incorporation of
this delta in speech-dispatcher.
Note: Either the installed socket needs to be started manually to
function correctly or the system needs to be rebooted.
[Test case]
Install the proposed speech-dispatcher and the snap[5] containing spd-
say. Then,
systemctl start --user speech-dispatcher.socket
snap run --shell geheim
$ XDG_RUNTIME_DIR=/run/user/1000 spd-say hi
[Regression potential]
If the socket communication were not working (e.g. connection
refused), then this would result in text-to-speech failing, even for a
not sandboxed program.
Do note, however, that if the socket were not available for whatever
reason (e.g. the user didn't start it manually nor rebooted), then the
sd_listen_fds(0) >= 1 test would be false and no regression would be
observed, as then the program would fallback to its usual operation.
