Perl(5)IO is not an async API - it has no way of passing in completion routines, for instance. > 3) Perl IO has conditional compilation for using stdio. > Dan has said no > STDIO > but are we going to abandon conditional support for > Parrot? > (I vote for ditching conditional STDIO support > because then its easier > to stop thinking in STDIO terms...) Unfortunately, I don't think we can completely do without stdio in parrot for one reason: miniparrot. Without doing a full configure.pl run, the _only_ I/O API we're guarranteed is a basic stdio. However, that being said, what we'll likely want to do is have a statically linked Miniparrot::IO module that provides wrappers over C stdio and we'll use _that_ in configure.pl. That way, we don't have to clutter up ParrotIO with stdio cruft. > 4) For platforms out there with broken or no async IO > support, do we > emulate > async (background thread or something) or just say, > "tough!?" Emulate as best we can. Nevertheless, if you're running MS-DOS or some equivalently-brain-damaged OS, there's not much we can do. But then, if you're writing serious event loops on DOS, you've probably got other problems to solve as well. > > I want comments now or else I threaten to post replies to > myself in a > creepy third > person way. No! Anything but that. BKS hates things like that! -- BKS __________________________________________________ Do You Yahoo!? Check out Yahoo! Shopping and Yahoo!
