[PATCH] Expand body only once for uffi:with-cstring.

Stephen Compall — 2008-07-23T04:54:27

Got an explosion in CLSQL-PostgreSQL with a uffi:with-cstrings expansion, as 7 strings makes 128 copies of the body. On the theory that the compiler can inline flets far easier than factor them, this patch puts the body in an flet and calls the resulting function from the two contexts `with-cstring' creates.

Conflicting symbols problem on OpenMCL/CCL whenloading CFFI

Daniel Katz — 2008-07-02T01:04:38

Hi - I just tried to load the latest CFFI from darcs into CCL 1.2, and I got a symbol conflict between CCL:COPY-FILE and ALEXANDRIA.0.DEV:COPY- FILE: When I look in the CFFI code, the problem seems to come from cffi-- openmcl.lisp where ALEXANDRIA and CCL are both being :use-d without any shadowing. As far as I can tell, there are no calls to either COPY-FILE function anywhere in the CFFI code, so it seems to me that choosing one of these functions to shadow the other should be a simple affair since it shouldn't matter at all which one is chosen.. Would it be possible to get this fixed? Thanks. Dan

strange behaviour of CFFI with LW on OS X

Antoine Allombert — 2008-06-25T15:09:26

Hello everybody, I face a weird situation with LW and CFFI on OS X 10.4. When I evaluate the form : > (cffi:with-foreign-pointer (ptr 2) (setf (cffi:mem-ref ptr :int 0) 0) (setf (cffi:mem-ref ptr :int 1) 1) (let ((i 0)) (loop for i from 0 below 2 collect (cffi:mem-ref ptr :int i)))) The result is : (256 1) The first value of the pointer has been turned from 0 to 256. I tried other similar tests using explicit "foreign-alloc" with similar results. Note that in each case, the last modified place of the pointer keeps his right value while the value of the other places of the pointer are changed. I use the correct package. So I am wondering if it could be a problem in my system. Any idea or ptoposition welcome. Regards.

WITH-FOREIGN-STRING allocates on heap?

Hans Hübner — 2008-06-20T04:21:07

Hi, is there a good reason why WITH-FOREIGN-STRING allocates the buffer on the heap instead of using WITH-FOREIGN-OBJECT, which will allocate on the stack on platforms that support it? Thanks, -Hans

First usages of CFFI

Marko Tapio Manninen — 2008-06-17T00:59:12

Hi, so far i have compiled some programs, that use CFFI, but now id like to create my own. As usual i counter my limits of knowledge and hope to find some answers here. I'm using libevent library (later doing same with libev), that has a simple event based server application, which i want to use from ccl / sbcl. I'll put two c functions first, and then some header information and finally some lisp code i have created. Im particularry interested getting some comments, how the work should be done. Yet there re two parts of the code, where i have stuck and they are: void evhttp_set_gencb(struct evhttp *http, void (*cb)(struct evhttp_request *, void *), void *cbarg) {} (defcfun ("evhttp_set_gencb" %evhttp-set-gencb) :void (http evhttp) ???) Actually same part occurs on evbuffer: void (*cb)(struct evbuffer *, size_t, size_t, void *); Regards, -Marko -------------------------------------------------------------------------------------------------------------------------------------- //

CFFI::SYMBOLICATE undefined

Chun Tian — 2008-06-12T07:00:35

Hi, CFFI developers I'm testing CFFI on this darcs url: http://common-lisp.net/project/cffi/darcs/cffi When I compiled CFFI, CMUCL and LispWorks both tell me: function CFFI::SYMBOLICATE is undefined in macro CFFI:DEFCVAR in file src/foreign-vars.lisp. Is this a bug? P.S. In LispWorks, I found this function in LW's system package: SYSTEM:SYMBOLICATE, I don't know if this function can be used. Regards, Chun Tian (binghe)

Foreign struct

Liam Healy — 2008-06-11T01:44:06

I'm having a problem defining/using a foreign struct for my package GSLL (http://common-lisp.net/project/gsll), an interface to the GNU Scientific Library (http://www.gnu.org/software/gsl/), written in C. I am trying to handle complex numbers; GSL has a struct defined to represent complex numbers in /usr/include/gsl/gsl_complex.h: typedef struct { double dat[2]; } gsl_complex; So I define (cffi:defcstruct complex-double-c (dat :double :count 2)) I set this value with a function (defun complex-to-gsl-df (number) (let* ((gsl (cffi:foreign-alloc 'complex-double-c)) (datslot (cffi:foreign-slot-pointer gsl 'complex-double-c 'dat))) (setf (cffi:mem-aref datslot :double 0) (realpart number) (cffi:mem-aref datslot :double 1) (imagpart number)) gsl)) When I pass a complex number generated with this function to a GSL function, I always get the following result: the real part is what I specified for the imaginary part, and the imaginary part is the number 5.2635442471208903e-315, which I dis

make-shareable-byte-vector in LispWorks 5.1

Chun Tian (binghe — 2008-06-10T17:54:19

Hi, CFFI developers There's another change from LispWorks 5.1's static array allocation: Instead of (sys:in-static-area (make-array 3 :element-type '(unsigned-byte 8) :initial-contents '(65 77 23))) We use this now: (make-array 3 :element-type '(unsigned-byte 8) :initial-contents '(65 77 23) :allocation :static) see http://www.lispworks.com/documentation/lw51/FLI/html/fli-130.htm#pgfId-1112879 I hope the patch in attach can be merged.
