So, either the callbacks +are set incorrectly, or they are called while they should not be. + +><i> the client was exiting with a message in the logfile about +</I>><i> being unable to load file "data/". Managed to eventually track +</I>><i> it down to some of the texture loading code in +</I>><i> code/nel/src/3d/landscape.cpp. The loading of the diffuse +</I>><i> texturemap doesn't do a check for textName == "" though +</I>><i> the loading of the alpha texture map does. Haven't worked +</I>><i> out yet why it's decided that the textName is "" (it's too +</I>><i> late ;)). I modified the code to do a test for textName == "" +</I>><i> and made it default to loading the CTextureCross texture. +</I> +That's the strange part. It should not be loading an empty file name +at all. I suppose the check doesn't hurt either, so we'll look at +integrating it in future commits. + +><i> As some other comments - processes are defaulting under linux to +</I>><i> some (IMHO) really ugly behaviour of 'fork'ing another process, +</I>><i> the sole purpose of this appears to be to let them run in the +</I>><i> background. I don't see any really good reason for doing this, +</I> +Well, there is one. Basically, if you look at these processes, you'll +see they first do a set of initialisations, then fork. The whole +fork-and-exit sequence is used to guarantee that service N+1 isn't +started before service N has at least performed the minimum required +initialisations. + +><i> since it can be quite easily achieved by 'nohup'ing it and +</I>><i> shoving an '&' on the end of the line. Am I missing something? +</I> +You could too, but you'd have to slide in a "reasonable" sleep N in +the shell startup script. With reasonable varying a lot. + +><i> (It makes it a bugger to debug, I can't run 'strace' on them effectively +</I>><i> etc etc. Obviously, i just commented the code out of my version ;) +</I>><i> Perhaps a commandline switch would be more appropriate?) +</I> +That'll be added, yes. + +-- +Vincent Archer Email: <A HREF="mailto:archer@nevrax.com">archer@nevrax.com</A> + +Nevrax France.
