PLUGIN/guile.libs.in. This is for including additonal libraries
needed for dynamic linking.
* Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
instead of PLUGIN/guile.libs.
PLUGIN/guile.libs.in. This is for including additonal libraries
needed for dynamic linking.
* Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
instead of PLUGIN/guile.libs.
* Makefile.am: Added explicit dependency "dynl.o: dynl.x".
occurrences of the given element from the list, not just the
first. This is how the Emacs Lisp functions behave, how the
analogous Common Lisp functions behave, and (I believe) how the
older Maclisp functions worked. I realize that this change may
break code, but it seemed better to break it before the Guile
release than after.
Their prototypes were already present in gc.h, but they weren't
implemented.
(scm_init_storage): Initialize scm_protects.
* root.c (scm_protects): New element of scm_sys_protects.
30 change. That file is only meant for communication between the
configuration process and load.c. If code linked against libguile
wants to get at the paths mentioned in libpath.h, it can call
functions declared in load.h.
use separate data pointers, to allow them to be designed
independently and reused.
(scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
Renamed from catch_body, catch_handler, and uncaught_throw; made
generically useful.
(struct scm_catch_body_data): Renamed from catch_body_data; moved
to throw.h.
(scm_catch): Use the above.
(scm_throw): Don't bother printing a message for an uncaught
throw; we establish a default handler in init.
* throw.h (scm_internal_catch): Prototype updated.
(scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
decls.
(struct scm_body_thunk_data): New structure, used as data
argument to scm_body_thunk.
* init.c (struct main_func_closure): New structure, packaging up
the data to pass to the user's main function.
(scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
(scm_boot_guile_1): Pass it through to invoke_main_func. Use
scm_internal_catch to establish a catch-all handler, using
scm_handle_by_message. This replaces the special-case code in
scm_throw.
(invoke_main_func): Body function for scm_internal_catch; invoke
the user's main function, using the main_func_closure pointer to
decide what to pass it.
* root.c (struct cwdr_body_data): Remove handler_proc member.
(cwdr): Use scm_handle_by_proc instead of cwdr_handler.
(cwdr_handler): Removed.
FIONREAD, since the latter doesn't detect EOF.
Throw error if neither select nor FIONREAD available.
* socket.c (scm_connect): take a port, not a fd object.
(scm_fill_sockaddr): throw an error if fam is not recognised.
(scm_bind): use scm_fill_sockaddr.
(scm_listen): take a port, not a fd object.
(scm_accept): take and return a port. return CDR in the car if
address can't be got
(scm_sock_fd_to_port): new procedure.
(scm_socket): use scm_sock_fd_to_port.
(scm_addr_vector): throw error if unrecognised address type.
take an extra argument with the calling procedure name.
(scm_getsockname): take a port. return #f if address can't be got.
(scm_getpeername): take a port. return #f if address can't be got.
(scm_recvfrom): take a port. return #f for address component if can't
be got.
(scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
* socket.h (SCM_P): update bind prototype.
* socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
include "feature.h".
(scm_socket): return a port, not a file descriptor object.
include "fports.h" and <unistd.h>
(scm_bind): take a port, not a file descriptor object.
take an extra argument for address args.
* net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
INADDR_NONE, INADDR_LOOPBACK.
* init.c: include net_db.h and not fdsocket.h.
(scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
* Makefile.am: corresponding changes.
* socket.h: renamed from fdsocket.h, fix names.
* net_db.h: renamed from socket.h, fix names.
* socket.c: renamed from fdsocket.c.
remove _sys from procedure names.
(scm_init_socket): rename from scm_init_fdsocket. include socket.x.
add "socket" to features list.
* net_db.c: renamed from socket.c.
remove _sys from procedure names.
(scm_init_net_db): rename from scm_init_socket. include net_db.x.
add "net-db" to features list.
include "net_db.h". don't include <sys/socket.h> or
<sys/un.h>.
(Here he goes again! Why do we put up with this?!)
* debug.h (scm_debug_frame): Make the 'vect' member a pointer to
an scm_debug_info structure, not an in-line array of them. Add
'info' member, to say how many vect elements we've used, for eval
frames.
* eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
a new variable debug_info_end to mark the end of vect, instead of
the address of the 'info' pointer itself.
[DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
&debug to scm_debug_frame *; debug is a real scm_debug_frame now.
(SCM_APPLY): Explicitly allocate space for debug.vect.
* debug.c (scm_m_start_stack): Same, for vframe.vect.
* stacks.c: Adjusted for new debug frame structure.
(RELOC_INFO, RELOC_FRAME): New macros.
(stack_depth, read_frames): Use them, and new scm_debug_frame
element 'info', instead of magically knowing that eval frames have
an info pointer sitting after vect.
(scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
RELOC_FRAME.
(scm_init_stacks): Formatting tweaks.
figure that out; this usually happens when one variable is only
initialized and used when a particular condition holds true, and
we know that condition will never change within a given invocation
of the function. In this case, we simply initialize the variables
to placate the compiler, hopefully to a value which will cause a
crash if it is ever actually used.
* print.c (scm_iprin1): Initialize mw_pos.
* read.c (scm_lreadrecparen): Initialize tl2, ans2.
* throw.c (scm_ithrow): Initialize dynpair.
* unif.c (scm_uniform_vector_ref): Initialize cra.
* struct.c (init_struct): Initialize prot.
* mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
variables aren't used uninitialized.
* error.h (scm_error, scm_syserror, scm_syserror_msg,
scm_sysmissing, scm_num_overflow, scm_out_of_range,
scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
scm_misc_error): Tell GCC that these functions never return.
* struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
out the field type, call abort if SCM_ASSERT returns, to placate
the optimizer.
* stacks.c (scm_make_stack, scm_last_stack_frame): abort if
scm_wta ever returns. We can't handle this case anyway, and this
gives the optimizer more information.
* unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
scm_wta ever returns.
In some cases, the code is fine, but GCC isn't smart enough to
figure that out; this usually happens when one variable is only
initialized and used when a particular condition holds true, and
we know that condition will never change within a given invocation

to placate the compiler, hopefully to a value which will cause a

(scm_must_malloc, scm_must_realloc): Added a hysteresis to the
rules for raising scm_mtrigger. Previously, unfortunate but not
unlikely circumstances could result in almost constant invokation
of the gc. Now, this situations should be less likely, but they
are not prevented completely.
