[haiku-development] Re: [PATCH] libroot improvements

Hey,
François Revol pisze:
Then i removed completly glibc and friends mixes from libroot and started porting libc and Sun math library from FreeBSD. Now it's working as expected, with full posix support (even c99), wide 

Hmm did you make sure it doesn't imply errno > 0 ?
C99 mandates that (at least some part of it, other parts being less consistent), and we violate it, so things like return -EFOO need to be looked after.
they are defined for fbsd as > 0, but using our versions, it seems to work fine 


chars enabled, support for locales, etc.
Don't worry, it won't break binary compatibility, because it's ported & enabled only for gcc4 build, gcc2 is still using old 
libroot+glibc&friends.


I'm wondering how that impacts headers and the rest...


Things noticed by me (and not only, thx for testing guys :P):
* system is noticable faster compared to other builds, i mean gui and boot; for virtual box on my machine (dont know how others and i didn't tested this on real hardware yet) boot time was decrased from 24-26 seconds to 14 (don't know the reason) 

Are you sure stuff like stdio are made threadsafe as with glibc ?
Also, how does BSD libc handle threading/cancelation points/... ?

I'm not sure yet, but it seems to be and it uses our version of pthreads




* gui is more responsible, i think it's because new sun math library


But is it less buggy ? :p

hehe, looking after benchmarks it was just a feeling i think :)


François.
