[Python-Dev] Apple PublicSource license [was: next vs darwin] (original) (raw)

I did another version of dynload_darwin that took a >10 line function from the dlcompat/dlopen.c code which uses an undocumented (at least in the man pages -- there's probably comments in the Darwin source code) non-public way around the public/private namespace problem we were having with the previous version.

I'm waiting for some folks on pythonmac-sig to test it and report back. I'm guessing that this solves the problem without requiring libdl. However it gets into the possible problem of including another license.

Could someone who undestands these issues a bit more than I, look at this:

Apple Public Source License: http://www.publicsource.apple.com/apsl/

BTW: Here's the magic code I added from dlcompat/dlopen.c: ( On the one hand, it's fairly short and trivial. On the other, I wouldn't have had a clue about this without reading the code! )

/*

{ static enum bool (*p)(NSModule module) = NULL;

if(p == NULL) _dyld_func_lookup("__dyld_NSMakePrivateModulePublic", (unsigned long *)&p); if(p == NULL){ #ifdef DEBUG printf("_dyld_func_lookup of __dyld_NSMakePrivateModulePublic " "failed\n"); #endif return(FALSE); } return(p(module)); }
