soon as GET-CHARACTER returns any character at all that was
previously read. This makes the continuation prompt appear
properly for partial expressions. Thanks to Neil Jerram!
in C for now.
* rdelim.scm: export the C primitives too.
* documentation.scm: use (ice-9 rdelim).
* filesys.c (scm_link): docstring fix.
* fports.h (scm_setfileno): obsolete declaration removed.
* posix.c: bogus popen declaration removed.
* rdelim.c: new file, split from ioext.c with new proc
scm_init_rdelim.
* rdelim.h: new file.
* Makefile.am: add rdelim.c and related files.
* init.c: call scm_init_rdelim. include rdelim.h.
* ice-9.scm (scm-line-incrementors read-line! read-delimited!
read-delimited read-line): moved to rdelim.scm.
scm-line-incrementors is not exported.
* boot-9.scm: import (ice-9 rdelim) for backwards compatibility,
for now.
* lineio.scm: use module (ice-9 rdelim).
* Makefile.am (ice9_sources): add rdelim.scm.
casts its result, so doesn't yield an lvalue per ANSI C.
* goops.c (s_scm_sys_set_object_setter_x): use
SCM_SET_ENTITY_SETTER.
(clear_method_cache): use SCM_SET_ENTITY_PROCEDURE.
* gc.h (SCM_GC_SET_CARD_BVEC): new macro. SCM_GC_CARD_BVEC casts
its result, so doesn't yield an lvalue per ANSI C.
(SCM_GC_SET_CARD_FLAGS): ditto for SCM_GC_GET_CARD_FLAGS.
(SCM_GC_CLR_CARD_FLAGS): redefined in terms of
SCM_GC_SET_CARD_FLAGS.
(SCM_GC_SET_CARD_FLAG, SCM_GC_CLR_CARD_FLAGS): ditto.
* gc.c (INIT_CARD): use the explicit setter macro to set the bvec.
* ioext.c (scm_read_string_x_partial, scm_read_delimited_x),
socket.c (scm_recvfrom): use the new macro, plus minor docstring
changes.
* ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
for fdes. if current input port is used, check that it's a file
port.
read-string!/partial.
* ports.c (scm_take_from_input_buffers): new procedure used by
scm_read_string_x_partial.
(scm_drain_input): use scm_take_from_input_buffers.
SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
SET_DESTROYED): new defines/macros.
(GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
(add_to_live_list): takes a `guardian_t *' now, not SCM.
(guardian_print): print more info.
(guardian_apply): check if the guardian is destroyed, and throw an
error if so. take one more optional argument `throw_p'.
(scm_guard): depending on the value of `throw_p', return a boolean
result.
(scm_get_one_zombie): remove redundant property test.
(guardian_t): represent the various (currently 3, I hope nothing
more gets added) boolean fields as bit flags.
(scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
(scm_destroy_guardian_x): new procedure.
* guardians.h: added prototypes for `scm_guardian_greedy_p' and
`scm_guardian_destroyed_p'. changed prototype for `scm_guard'.
`weak_keys' and `weak_values' flags out of the inner loop.
* guardians.c: (greedily_guarded_prop): deleted.
(greedily_guarded_whash): new variable. a doubly-weak hash table
used to keep the "greedily hashed" object property. the previous
implementation (via primitive object properties) was incorrect due
to its only-the-key-is-weak semantics.
(scm_guard, get_one_zombie, scm_init_guardians): use/init
`greedily_guarded_whash'.
