Oh Christ...
I'm going about this all the way wrong. I was focussing on matching the numbers inside the LUA scripts, patching the code to be indifferent to the sign change, but the whole point of this jive_jiffies() thing is for all independent components to have their time values synchronized. And so even if I can get the LUA part to continue running with negative values for time this is bound to result in the unwanted behaviour that led to the introduction of jive_jiffies() in the first place. So let's break this down. As I see it there are two separate issues that require addressing: - *sign change* There is a difficult way and a simple way to address this. The problem with the simple way is that this requires the jive executable to be recompiled and therefore this is not a simple patch. The difficult and user patchable way is to handle the sign change inside the LUA scripts and the most straight forward method in this case will likely be to change all references to `getTicks()` to a new function `getCorrectedTicks()` that adds 4,294,967,296 when `getTicks()` returns a negative number. - *max integer value overrun* Be noted that it will be rather pointless to even start addressing this issue without having considered #1 first. As has been stipulated earlier the LUA number format is different from what `jive_jiffies()` returns. More specifically, `lua_number` has a much higher maximum value than the `uint32_t`that is used internally inside the jive executable *AND* the ALSA backend. At this point I'm unsure what would be the best or even simplest way to address this as both methods imply a fairly big change to the code base. Implementing some MAX_VAL routine inside the LUA scripts to handle loop issues is one method, the other one would involve changing the value type to be compatible all over the board (i.e. a double) which appears to have the highest chance of not running into other issues, be it somewhat dubious to store an integer value in a floating point type. ------------------------------------------------------------------------ gordonb3's Profile: http://forums.slimdevices.com/member.php?userid=71050 View this thread: http://forums.slimdevices.com/showthread.php?t=111650 _______________________________________________ Radio mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/radio
