* libguile/foreign.c:
* libguile/foreign.h: Rework interface to be more pointer-centric.
Details are:
(SCM_FOREIGN_TYPE_STRUCT, SCM_FOREIGN_TYPE_POINTER): Removed; now the
pointer in a foreign is first-class. If it points to a native type
like uint32, then it still has a tag; but if it points to something
else, like a struct or a pointer or something, then its type is VOID
(i.e., void*).
(SCM_FOREIGN_POINTER): Rename from SCM_FOREIGN_OBJECT.
(SCM_FOREIGN_VALUE_REF, SCM_FOREIGN_VALUE_SET): Rename from
SCM_FOREIGN_OBJECT_REF and SCM_FOREIGN_OBJECT_SET, to indicate that
they only work with value types.
(SCM_FOREIGN_HAS_FINALIZER): Reserve a bit to indicate if the foreign
pointer in question has a finalizer registered.
(SCM_FOREIGN_LEN): For void* pointers, optionally store the length in
bytes of the associated memory region.
(SCM_FOREIGN_VALUE_P): Rename from SCM_FOREIGN_SIMPLE_P.
(SCM_VALIDATE_FOREIGN_VALUE): Rename from SCM_VALIDATE_FOREIGN_SIMPLE.
(scm_take_foreign_pointer): Rename from scm_c_take_foreign. Remove
scm_c_from_foreign.
(scm_foreign_type): New accessor.
(scm_foreign_ref, scm_foreign_set_x): Take some optional args, used
when dereferencing void pointers.
* libguile/dynl.h:
* libguile/dynl.c (scm_dynamic_pointer): New function, used by
scm_dynamic_func. Adapt code to foreign.h changes.
* libguile/goops.c (scm_enable_primitive_generic_x)
(scm_set_primitive_generic_x): Use the SCM_SET_SUBR_GENERIC macro.
* libguile/gsubr.c (create_gsubr): Adapt to API change.
* libguile/gsubr.h (SCM_SUBRF, SCM_SUBR_GENERIC): Store the pointer
directly, not indirected.
* libguile/snarf.h (SCM_DEFINE, SCM_IMMUTABLE_FOREIGN): Store subr
pointers directly. Adapt to SCM_FOREIGN_TYPE_VOID change.
* libguile/vm-i-system.c (subr-call): Access the void* directly.
* libguile/dynl.c (scm_dynamic_func, scm_dynamic_call)
(scm_dynamic_args_call): Change the representation of dynamic
functions to be foreign objects. Shouldn't affect any users, as people
should be treating the return value of dynamic-func as an opaque
object.
* libguile/Makefile.am (libpath.h): Fix SCM_LIB_DIR to point to the
libdir, not pkglibdir. Add SCM_EXTENSIONS_DIR, for a dir to put in the
dynamic-link search path that's not managed by ldconfig or the like;
and put this dir in the "extensionsdir" key of %guile-build-info.
* libguile/dynl.c (sysdep_dynl_init): Rename the installed-libdir
environment var to GUILE_SYSTEM_EXTENSIONS_PATH (from
GUILE_SYSTEM_LTDL_PATH). Also add SCM_EXTENSIONS_DIR to the ltdl
search path in the default case.
* meta/uninstalled-env.in: Adapt override to match.
* meta/guile-2.0.pc.in: Add extensionsdir, so you can pkg-config
--variable=extensionsdir guile-2.0.
* libguile/Makefile.am (libpath.h): Fix pkgdatadir, pkglibdir, and
pkgincludedir entries. Add a new define, SCM_LIB_DIR.
* libguile/dynl.c (sysdep_dynl_init): Add the libdir to the libltdl
search path. Should fix
http://thread.gmane.org/gmane.lisp.guile.bugs/4289/focus=4296 -- that
is, it should allow guile to be invoked from whereever it is
installed, without munging LTDL_LIBRARY_PATH or the like variables.
There is a trick though -- during the build, we don't want to be
looking in the $libdir for loadable modules. So as with
GUILE_SYSTEM_PATH, we have GUILE_SYSTEM_LTDL_PATH.
* meta/uninstalled-env.in: Set GUILE_SYSTEM_LTDL_PATH to "" when
building.
"-I$(top_srcdir)/libguile-ltdl".
(libguile_la_LIBADD): Use @LIBLTDL@ instead of
"../libguile-ltdl/libguile-ltdl.a".
* guile.c, dynl.c: Switched to using libltdl directly. Replaced
all references to scm_lt_* with just lt_*. Include <ltdl.h>
instead of <libguile-ltdl.h>.
net_db.c, fports.c, filesys.c, eval.c, deprecation.c, dynl.c:
Replaced uses of SCM_STRING_CHARS with proper uses of
scm_to_locale_string. Replaced SCM_STRINGP with scm_is_string.
Replaced scm_mem2string with scm_from_locale_string.
* simpos.c, posix.c (allocate_string_pointers, environ_list_to_c):
Removed, replaced all uses with scm_i_allocate_string_pointers.
scm_ushort2num, scm_int2num, scm_uint2num, scm_long2num,
scm_ulong2num, scm_size2num, scm_ptrdiff2num, scm_num2short,
scm_num2ushort, scm_num2int, scm_num2uint, scm_num2long,
scm_num2ulong, scm_num2size, scm_num2ptrdiff, scm_long_long2num,
scm_ulong_long2num, scm_num2long_long, scm_num2ulong_long):
Discouraged by moving to discouraged.h and discouraged.c and
reimplementing in terms of scm_from_* and scm_to_*. Changed all uses
to the new scm_from_* and scm_to_* functions.
SCM_INUM): Deprecated by reenaming them to SCM_I_INUMP, SCM_I_NINUMP
and SCM_I_INUM, respectively and adding deprecated versions to
deprecated.h and deprecated.c. Changed all uses to either use the
SCM_I_ variants or scm_is_*, scm_to_*, or scm_from_*, as appropriate.
SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into "deprecated.h".
Replaced all uses with scm_is_false, scm_is_true, scm_from_bool, and
scm_is_bool, respectively.
explicit what happens.
* guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
scm_lt_dlopenext, and scm_lt_dlerror.
(sysdep_dynl_unlink): switch to scm_lt_dlhandle, scm_lt_dlclose,
and scm_lt_dlerror.
(sysdep_dynl_func): switch to scm_lt_dlhandle, scm_lt_dlsym,
and scm_lt_dlerror.
(sysdep_dynl_init): switch to scm_lt_dlinit();
defined. They don't do anything useful, especially since the
only case where DYNAMIC_LINKING is undefined seems to be
when --with-modules=no is given to configure, which is basically
requesting that the "dynamic linking module" be omitted.
* Makefile.am (libguile_la_SOURCES): move dynl.c from
libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.
* extensions.c (load_extension): check DYNAMIC_LINKING for
scm_dynamic_call.
* init.c (scm_init_guile_1): check DYNAMIC_LINKING for
scm_init_dynamic_linking.
* configure.in: check dynamic linking before modules. Add dynl.c
if dynamic linking is available, i.e., unless --with-modules=no
was given to configure.
(scm_make_argv_from_stringlist): static procs: 1) renamed both to
allocate_string_pointers. 2) simplified: don't reallocate the
strings, just make an array of pointers 3) avoid memory leaks on
error 4) let the procedure report errors in its own name.
Consequences: 1) the procedures now assume that SCM strings are
nul-terminated, which should always be the case. 2) Since strings
are not reallocated, it's now possible for strings passed to
dynamic-args-call to be mutated.
non-zero is returned from a port or smob free function.

appropriate. Return zero from smob and port free functions.
