[cffi-devel] CFFI-GROVEL ASDF integration

Hi Luis,

This is just an update. My son was born recently and I haven't had much time to work on this.

Yes you are correct. The problem can be seen with ASDF::TRAVERSE returning the wrong plan:

((#<ASDF:LOAD-OP NIL {100793C8D3}>
  . #<ASDF:CL-SOURCE-FILE "osicat" "osicat-sys" "osicat-sys">)
 (#<ASDF:LOAD-OP NIL {100793C8D3}> . #<ASDF:MODULE "osicat" "osicat-sys">)
 (#<CFFI-GROVEL::PROCESS-OP NIL {10076A7263}>
  . #<CFFI-GROVEL:GROVEL-FILE "osicat" "posix" "basic-unixint">)
 (#<ASDF:LOAD-OP NIL {10077E2133}>

  . #<CFFI-GROVEL:GROVEL-FILE "osicat" "posix" "basic-unixint">)
....

For some reason there exists a PROCESS-OP on "basic-unixint" before the LOAD-OP on "packages". 

I am still trying to ascertain how this occurs though. I am unable to reproduce the incorrect plan with my simpler MY-LOAD-OP, MY-COMPILE-OP, MY-CL-SOURCE-FILE, MY-PROCESS-OP and MY-PROCESS-OP-INPUT definitions.

I will keep hunting. 

Have a good weekend.
