[B2-devel] problems caused(?) by recent patches

[Ronald P. R. <ron...@xs...>]

In Emaculation.com forums, Alexei Svitkine asked me to mail to this  
list about patches I needed to revert before building SheepShaver (and  
BasiliskII) for Mac OS X in order to avoid problems.


The problems with the "precise timer patch" were discussed in the  
basilisk-devel list between October 23 and October 28. Those problems  
were the reason for me to make the 25-10-2009 build for  
Emaculation.com within days after the 18-10-2009 build.

In my last October 25 message to the basilisk-devel list I told which  
files I used for the 25-10-2009 build to omit the "precise timer  
patch" and the "sdl-audio patch".

The "sdl-audio patch" apparently made sound for most users worse  
rather than better. Users of both BasiliskII and SheepShaver builds  
created after that patch was added, complained about the problems for  
months and reported considerable improvement when I posted builds of  
both without the patch. That happened before I joined this mailing  
list. The problems were sound delays, stuttering, even skipping of  
sounds. The problem was more serious in BasiliskII than in SheepShaver.

I do not know whether these patches actually cause the problems or  
just make bugs in other parts of the code apparent.

I did not yet try to make new builds after the patch for Snow Leopard  
x86_64 compatibility by Jean-Pierre Chombier were added. I do not have  
Snow Leopard installed yet. Jean-Pierre Chombier also posted test  
builds with SDL 1.2.14 that used the "hardware cursor" (before only  
possible with SDL 1.2.10), but again with the sdl-audio patch and thus  
with again the sound problems.

He built with SDL.Framework in the SheepShaver.app package, while my  
builds have so far been with sdl static (makes a smaller application).
