[cffi-devel] [PATCH] emulating LONG-LONG on ECL
by Stelian Ionescu 20 Jul '07

20 Jul '07

Attached there is a patch made against the main branch(not the newtypes one) which adds :UNSIGNED-LONG-LONG and :LONG-LONG to ECL; to be more specific: 1) it adds a new feature: CFFI:EMULATED-LONG-LONG(not sure this is a good name - see the callbacks issue below) 2) it calculates at compile time the machine endianess and pushes a new feature, either :LITTLE-ENDIAN or :BIG-ENDIAN 3) %MEM-REF and %MEM-SET are renamed to %NATIVE-MEM-REF and %NATIVE-MEM-SET while the new %MEM-REF and %MEM-SET dispatch on the effective type using CANONICALIZE-FOREIGN-TYPE(which is forward-referenced but it should be ok) 4) it adds compiler macros for %NATIVE-MEM-REF and %NATIVE-MEM-SET this patch passes the DEREF.*LONG-LONG memory tests(which I ran manually since ECL seems to have some problems in running the tests) two are the problems I've encountered: 1) callbacks don't work since actually ECL doesn't have LONG-LONG. this can be "fixed" by stating in the docs that on platforms where LONG-LONG is emulated callback simply don't work. 2) although possibly not related to CFFI, when loading IOLIB-POSIX I got this: NIL is not of type REAL. Broken at CFFI::NOTICE-FOREIGN-STRUCT-DEFINITION. IOLIB-POSIX>> :backtrace Backtrace: CFFI::NOTICE-FOREIGN-STRUCT-DEFINITION > eval I'll investigate further this issue. -- (sign :name "Stelian Ionescu" :aka "fe[nl]ix" :quote "Quidquid latine dictum sit, altum videtur.")

hi! we are experimenting with the new branch and a question popped up: why is T the default of *suppress-character-coding-errors*? it seems to us that NIL should be better for less quiet surprises... -- attila

[cffi-devel] Bug in uffi-compat::%deref-pointer
by Aurelio Bignoli 20 Jun '07

20 Jun '07

The function uffi-compat::%deref-pointer still calls cffi::translate-type-from-foreign, but the method is no longer available at least since the 31 may patch. The same is true for %deref-pointer setf expander and cffi::translate-type-to-foreign. I tried to use cffi::translate-{from|to}-foreign and it seems to work. Regards, Aurelio
