[cffi-devel] Performance of CFFI:PARSE-TYPE
by Hans Hübner 02 Jun '08

02 Jun '08

Hi, I have recently switched to using the cffi+lotsastuff version and I find it very slow for certain applications. The reason for this is that PARSE-TYPE is called from FOREIGN-TYPE-SIZE, and PARSE-TYPE is very expensive. It would be relatively easy to cache the type parsing results in a hash table, but before moving forward in that direction, I'd like to know what your opinions on this is. Thanks, Hans

[cffi-devel] Documentation build errors
by Rupert Swarbrick 31 May '08

31 May '08

Hi there, In my quest to work out what I've broken (this time) in the project I'm working on when I'm not doing something more useful, I just pulled the latest version of cffi (main branch) with darcs and rebuilt the documentation... Well almost. Various texinfo compilation errors. I don't really know texinfo, but the change below seems to sort them out (btw, this is the output of my first non-pull, non-get darcs command. Exciting! Although also hard to work out whether it's useful - some sort of versioning would presumably be more helpful... But maybe that's the point about darcs. Hmm. Anyway, I've added a seemingly missing @table command and corrected a capital T. So manually fixing it would probably be easy too :)) Rupert hunk ./doc/cffi-manual.texinfo 4528 -@seealso{Other types} (@code{:string} type) @* +@seealso{Other Types} (@code{:string} type) @* hunk ./doc/cffi-manual.texinfo 6174 +@table @var +

[cffi-devel] defcfun optimization idea
by Attila Lendvai 22 May '08

22 May '08

hi! when i was optimizing time functions in osicat i was pondering that cffi:defcfun could add an ftype declaim to the emitted defun based on the ffi types. it may be only a heuristic, but most of the time the return value could be annotated which would help the compiler. it would also be useful if there was a way to tell defcfun to declare the emitted defun to be inline. </random ideas> -- attila

[cffi-devel] null-pointer, *INLINE-EXPANSION-LIMIT* exceeded
by Tamas K Papp 22 May '08

22 May '08

Hi, When compiling a function, I get this strange error message: ; in: DEFUN UMFPACK-SOLVE ; (CFFI-SYS:NULL-POINTER) ; ; note: *INLINE-EXPANSION-LIMIT* (200) was exceeded, probably trying to ; inline a recursive function. The code looks like this, it is in my cl-sparsematrix package (asdf-installable), cffi version is 20080217, using SBCL 1.0.16.0. The code looks like below, I tried to come up with a smaller example but couldn't (does not happen in one-liners using null-pointer). null-pointer does not look recursive to me... umfpack-catch-error is a macro. If there is something obvious I am doing wrong, please let me know, if not, helpful hints on how to determine what is going on are welcome. (defun umfpack-solve (a-csc b &optional (symbolic (umfpack-symbolic a-csc))) "Use umfpack-solve to solve the sparse system A x = b, where a-csc is A packed in csc format. If you are solving many systems of the same shape, you should precalculate the symbolic object and supply it for a minor increase in speed." (with-slots (nrow ncol ap ai ax) a-csc (assert (= nrow ncol)) ; need square matrix (let ((x (make-ffa nrow :double))) ; Ax=b (with-slots ((symbolic-pointer pointer)) symbolic (with-pointers-to-arrays ((ap ap-pointer :uint32 (length ap) :copy-in) (ai ai-pointer :uint32 (length ai) :copy-in) (ax ax-pointer :double (length ax) :copy-in) (x x-pointer :double (length x) :copy-out) (b b-pointer :double (length b) :copy-in)) (with-foreign-pointer (numeric-goes-here (foreign-type-size :pointer)) ;; calculate Numeric object (format t "umfpack: calculating numeric object~%") (umfpack-catch-error (umfpack_di_numeric ap-pointer ai-pointer ax-pointer symbolic-pointer numeric-goes-here (null-pointer) (null-pointer))) ;; solve system (format t "umfpack: solving system~%") (umfpack-catch-error (umfpack_di_solve 0 ap-pointer ai-pointer ax-pointer x-pointer b-pointer (mem-ref numeric-goes-here :pointer) (null-pointer) (null-pointer)))) ;; return x x)))))) Thanks, Tamas

[cffi-devel] Merging the cffi+lotsastuff branch; new dependencies
by Luís Oliveira 17 May '08

17 May '08

Hello, I'd like to merge cffi+lotsastuff[1] with the main branch soon. People have started using that branch in several projects and that has generated unnecessary confusion. This branch includes the following new features: - efficient external-format support for foreign strings - cffi-grovel - emulated long-long types - other minor stuff The only problem is that this branch brings in 3 new dependencies: babel[2], trivial-features[3] and alexandria[4]. Is this a big problem? I hope it isn't and I'll do the merge soon unless there are any objections.
