[tuxdroid-user] Daemon updates on svn

[David B. <da...@ja...>]

Philippe, I saw your commits for dropping privileges, I just tried the  
head revision and it works fine here. Feel free to commit whatever you  
think is good on svn. I don't manage the daemon myself and anyway you're  
much better than me so I don't see why I should review your patches for  
acceptance :-) Will ask remi to do the same for the tuxttsdaemon.

Also thanks to Damien (neimad) who also made some great job cleaning the  
current daemon. Srikanta, I don't forget you but I still didn't get time  
to read and test your cpp daemon, but I'll do it for sure. But I keep  
looking at your commits with attention ;-)

Never mind (yet :-).
It still needs to walk quite a way to reach its end.
Haven't been able to work much on it from past 6
days, as I was a bit tied up in my work. Hoping to
get more time after this weekend! :-)

Ok but there will be some more changes for tuxttsdaemon.
If we want to use the same least privileges principle we've to:
- have sufficient privileges to open the ALSA channel
- drop the privileges just after opening the channel

But from this little test I can see that tuxttsdaemon
tries to open the channel only when some text is rendered.

nobody@mercure:/$ tuxttsdaemon
-----------------------------------
Tux TTS Daemon V0.2.9
Acapela group Text to speech system
Kysoh 2007.
-----------------------------------
Voice list:
[Ryan8k]
[Bruno8k]
[Julie8k]
[Heather8k]
TCP server : started
TCP server : client incomming
### oops little typo to fix here: *incoming*

### now from gtdi I try to play sth:
ALSA lib pcm_hw.c:1357:(_snd_pcm_hw_open) Invalid value for card
cannot open audio device hw:2,1 (No such device)
Erreur de segmentation
### Some better error handling than core dump is welcome too ;-)

And if the channel is not maintained opened all the time but
reopened each time a text is rendered we cannot drop
the privileges :-(

There is a separate alsa channel only for tts, you could open
the channel at startup, drop privs and keep it opened.
