[Python-checkins] CVS: python/dist/src/Modules posixmodule.c,2.187.2.2,2.187.2.3

2001年7月11日 15:27:40 -0700

Update of /cvsroot/python/python/dist/src/Modules
In directory usw-pr-cvs1:/tmp/cvs-serv15531/Modules
Modified Files:
 Tag: release21-maint
	posixmodule.c 
Log Message:
Re-do the broken-nice() patch to break less platforms. Hopefully none :P
Also note that it isn't just Linux nice() that is broken: at least FreeBSD
and BSDI also have this problem. os.nice() should probably just be emulated
using getpriority()/setpriority(), if they are available, but that isn't
worth putting in 2.1.1.
