Re: [Linuxsampler-devel] [linuxsampler] Latest CVS commit

[Vladimir S. <ha...@so...>]

Hi All,

I've checked some stuff in a few minutes ago.
Changes include: multiple connection support and event subsctiption support.

I left the tokenizer/parser largely intact for now.
LSCPServer remains singlethreaded and i think it will be sufficient for 
what we use it for.
The only issue is that execution of a command could take a long time 
(for example, loading an instrument) but i think we have already 
established that the client will not like that and we will have things 
of that nature done in the background anyway.

As far as events go i've added the infrastructure but i have not made 
all the changes to the code everywhere to actually start sending events 
(yet). I've provided a quick sample on how this could be done by sending 
a MISCELLANEOUS (debugging) event when a new client connection is 
established and when an existing connection is terminated. This is just 
an example for how to use those "guts" and we should be able to add 
actual event sending very easily.
I've spent most of the energy in trying to not block any thread that is 
originating a notification even LSCPServer thread is busy. I've added 
Trylock() support to Mutex class to be able to do that.
If we need to in the future we'll be able to create new event types in 
real time. I've left some hooks for that in case we need to do that.

Please check it out and let me know where the bugs are. I haven't done 
much testing on it yet, but i've got a long weekend ahead so i hope i'll 
do some later (after i make check more stuff in).

My plans for this weekend are:
1) Refactor the factories :) a little bit to avoid issues with 
constructors and parameters (as discussed previously)
2) Look at the audio device/audio channel stuff. (card parameters, 
mixing channels, etc)
3) Maybe look at converting the MacOS MIDI drivers.
4) Testing, playing with the GUI, updating the spec (if there is enough 
time).

Let me know what you think. Plans will be altered depending on feedback 
received.

Regards,
Vladimir.
