[cffi-devel] MEM-REF and BARE-STRUCT-TYPE-P issue
by CRLF0710 21 Jan '13

21 Jan '13

Hi all. #1 In src/types.lisp there is following code in function MEM-REF: .... (if (aggregatep parsed-type) (if (bare-struct-type-p parsed-type) .... and its compiler macro has similiar code. However, the gf bare-struct-type-p has no method for foreign-array-type whose objects will obviously pass the aggregatep test. So it breaks some code (on ccl). I suggest that case be added as a method too?(What should it (and even more user-defined types) return?) Or should the checking code be modified here? (As i understood, the whole bare struct mechanism is for compatibility...) #2 And another thing, i've realized that in my last modification to the STRUCTURE-BY-VALUE-P function (the modification is already pushed to the repo) i should have tested to see if it is a bare struct type. Without the check it will put some deprecated style code into using libffi, which also works correctly but involves unnecessary libffi dependency. Should I fix that? Regards, Charles Lew -- Wir müssen wissen; wir werden wissen! CrLF.0710

[cffi-devel] cstruct in groveller needs to escape %
by Greg Pfeil 07 Jan '13

This form: (cstruct %foo "foo" …) errors, as “%FOO” ends up literally in some C format string. “%” needs to be escaped as “%%”. CSTRUCT is probably not the only place it happens, but it’s where I’ve run into it.

G'day, There is an issue with the ASDF component of CFFI-GROVEL when running on ECL. The problem stems from ASDF:OUTPUT-FILES returning two items. The attached patch hopes to handle this situation. Thanks Mark
