[cffi-devel] CFFI 0.10.0 released!
by Luis Oliveira 29 Jul '08

29 Jul '08

Hello, It's been a while since CFFI's previous release, almost two years. During this period, a lot of development work happened and lots of cool new features were implemented. Here's a brief highlight of some of the important changes: * foreign string encodings using Babel. UTF-8 becomes the default encoding for foreign strings. * improved foreign type system that takes better advantage of CLOS features. * emulated :long-long types on Lisps whose native FFI doesn't support these types. * integrated a groveller inspired by SBCL's sb-grovel. * support for the stdcall calling convention. * removed finalizer-related code in favor of trivial-garbage. * function and variable lookups can now be linked to a specific foreign library instead of assuming a global namespace. * the cffi-features package has been deprecated in favour of trivial-features. CFFI-specific features are now interned in the CFFI-SYS package. * dozens of bug fixes and minor enhancements. The long hiatus between releases caused all sorts of problems and confusions. Hopefully that won't happen again and you'll see more frequent CFFI releases in the future. -- Luís Oliveira http://student.dei.uc.pt/~lmoliv/

[cffi-devel] Passing struct by value, kind of
by Markus Flambard 27 Jul '08

27 Jul '08

Hello lispers! I know that CFFI doesn't support passing structs by value. What I'm wondering is, is it possible to squeeze in a small struct by instead passing it as an int (or something) of the same size as the struct? Example: struct MyStruct { int32 x, y; }; int myFunction(struct MyStruct s); Could I force/lie to CFFI and declare 's' to be of type int64 and pass it that way? I tried something similar, but then CFFI (well, ClozureCL) just couldn't resolve the function symbol.. -- Markus Flambard 6A63 2761 0A9E E510 DDAF C796 A3DF AB90 9C7C AD5C

[cffi-devel] [PATCH] Expand body only once for uffi:with-cstring.
by Stephen Compall 23 Jul '08

23 Jul '08

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. -- a Mr. Fleming wishes to study bugs in smelly cheese; a Polish woman wishes to sift through tons of Central African ore to find minute quantities of a substance she says will glow in the dark; a Mr. Kepler wants to hear the songs the planets sing. --Carl Sagan, "The Demon-Haunted World"

[cffi-devel] Conflicting symbols problem on OpenMCL/CCL when loading CFFI
by Daniel Katz 02 Jul '08

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: > CL-USER> (asdf:oos 'asdf:load-op :cffi) > ; loading system definition from /Users/dkatz/dev/lisp/libs/clbuild/ > systems/cffi.asd into #<Package "ASDF0"> > ; registering #<SYSTEM CFFI #x8754B3E> as CFFI > ; loading system definition from /Users/dkatz/dev/lisp/libs/clbuild/ > systems/babel.asd into #<Package "ASDF0"> > ; registering #<SYSTEM BABEL #x87910EE> as BABEL > ; loading system definition from /Users/dkatz/dev/lisp/libs/clbuild/ > systems/alexandria.asd into #<Package "ASDF0"> > ; registering #<SYSTEM :ALEXANDRIA #x87BA8B6> as ALEXANDRIA > ; loading system definition from /Users/dkatz/dev/lisp/libs/clbuild/ > systems/trivial-features.asd into #<Package "ASDF0"> > ; registering #<SYSTEM TRIVIAL-FEATURES #x86F53D6> as TRIVIAL-FEATURES > > Using #<Package "CCL"> in #<Package "CFFI-SYS"> > would cause name conflicts with symbols inherited by that package: > ALEXANDRIA.0.DEV:COPY-FILE COPY-FILE > > [Condition of type CCL::USE-PACKAGE-CONFLICT-ERROR] > > Restarts: > 0: [CONTINUE] Try again to use #<Package "CCL"> in #<Package "CFFI- > SYS"> > 1: [RESOLVE-BY-SHADOWING-IMPORT] SHADOWING-IMPORT one of each pair > of conflicting symbols. > 2: [RETRY-COMPILE-FILE] Retry compiling #P"/Users/dkatz/dev/lisp/ > libs/clbuild/source/cffi/src/cffi-openmcl.lisp" > 3: [SKIP-COMPILE-FILE] Skip compiling #P"/Users/dkatz/dev/lisp/ > libs/clbuild/source/cffi/src/cffi-openmcl.lisp" > 4: [RETRY] Retry performing #<COMPILE-OP NIL #x85D71C6> on #<CL- > SOURCE-FILE "cffi-openmcl" #x85C588E>. > 5: [ACCEPT] Continue, treating #<COMPILE-OP NIL #x85D71C6> on #<CL- > SOURCE-FILE "cffi-openmcl" #x85C588E> as having been successful. > 6: [ABORT] Return to SLIME's top level. > 7: [ABORT-BREAK] Reset this process > 8: [ABORT] Kill this process > > Backtrace: > 0: (CCL::USE-PACKAGE-1 #<Package "CFFI-SYS"> #<Package "CCL">) > 1: (USE-PACKAGE '("ALEXANDRIA" "CFFI-UTILS" "CCL" "COMMON-LISP") > #<Package "CFFI-SYS">) > 2: (CCL::%DEFINE-PACKAGE "CFFI-SYS" 'NIL 'NIL 'NIL 'NIL 'NIL > '("ALEXANDRIA" "CFFI-UTILS" "CCL" "COMMON-LISP") 'NIL 'NIL '("% > CALLBACK" "%DEFCALLBACK" "%FOREIGN-SYMBOL-POINTER" > "WITH-POINTER-TO-VECTOR-DATA" "MAKE-SHAREABLE-BYTE-VECTOR" > "NATIVE-NAMESTRING" "%CLOSE-FOREIGN-LIBRARY" > "%LOAD-FOREIGN-LIBRARY" "%FOREIGN-TYPE-SIZE" > "%FOREIGN-TYPE-ALIGNMENT" ...) 'NIL) 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
