Icecast dev - Nov 2007 - checkpoint into Ices2

Hello,

I'd like to extend Ices2 in order to make it capable of managing 
checkpoints.

My assignment is to write a high-availability streaming server using 
OpenAIS. I decided to use Icecast and Ices.

Ices should periodically save relevant information to a checkpoint, so 
that when it crashes and then restarts, it can continue to provide the 
stream from the point it left off, based on the information in the 
checkpoint.

I am, however, not sure what information I have to put into the 
checkpoint and which source files should I modify to do so, as there a 
more than a dozen of them.

I would highly appreciate some help.

Thank you in advance,

tom

First, if Ices is crashing for you then this is something that needs 
looking at.  Ices should be able to run indefinitely without crashing.

Apart from that, in my opinion it would be far easier to write a program or 
script to provide next track info to ices, and have it keep its own state 
information.  It could then serve Ices the same track name as the one it 
crashed on. Of course, there is the issue of it figuring out if it is being 
called after a crash or simply after the end of the previous track, but 
this is probably something that can be figured out.  Maybe have it check to 
see if the appropriate time has elapsed since it was last called.

At any rate, this would allow you to do what you want without modifying 
Ices in any way.

Geoff.
