1.8/1.9 compiled library binary compatibility

Hi

I’m wondering whether extension libraries compiled against 1.8 will work
with 1.9, and/or the other way around.

I know the C API is little-changed, but will people offering add-ons
binaries need to offer two versions?

Also - if it should work, should I be worried about a particular library
if it’s not currently working - or just be patient and assume it’s down
to 1.9 being work in progress?

I was wondering the same thing. More specifically, I was wondering if
Mongrel was working with YARV yet. That then got me wondering if the IO
patterns Zed S. seemed to be frustrated with in MRI had been fixed in
YARV, and whether we’d (fingers crossed) see even more of a speed bump
to serving HTTP at some point in the future. Just call me foolishly
optimistic if you like :slight_smile:

No, impossible in both cases. For instance, object type flags
were added/changed in 1.9, and also structs.
