* module/ice-9/r4rs.scm (call-with-input-file, call-with-output-file): Rewrite
with call-with-values.
(with-input-from-file): use call-with-input-file.
(with-output-to-file, with-error-to-file): use call-with-output-file.
Update docstrings to make clear that multiple values may be yielded.
* libguile/goops.h:
* libguile/goops.c (scm_i_define_class_for_vtable): New internal helper,
defines a class for a vtable, relying on the name slot being set
correctly.
(scm_class_of, create_struct_classes): Use the local vtable-to-class
map instead of scm_struct_table.
* libguile/struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME)
(SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS, scm_struct_table)
(scm_struct_create_handle): Deprecate these internals of the map
between structs and classes.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_struct_create_handle): Deprecated code over
here now.
* libguile/hashtab.c (scm_hashq_get_handle, scm_hashq_create_handle_x)
(scm_hashv_get_handle, scm_hashv_create_handle_x)
(scm_hash_get_handle, scm_hash_create_handle_x)
(scm_hashx_get_handle, scm_hashx_create_handle_x): Don't allow these
functions to be called on weak hash tables, as we have no idea when
the GC will null out fields of the handle, and set-cdr! won't register
disappearing links, and set-car! would never work of course.
* libguile/objprop.c (scm_object_property_set_x): Use ref and set!
instead of create-handle and set-cdr!, as it is a weak hash table.
(scm_set_object_properties_x): Likewise.
* libguile/deprecated.c (scm_primitive_property_ref)
(scm_primitive_property_set_x): Avoid getting handles to elements in a
weak hash table, as that's not going to work very well.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_whash_get_handle, SCM_WHASHFOUNDP)
(SCM_WHASHREF, SCM_WHASHSET, scm_whash_create_handle)
(scm_whash_lookup, scm_whash_insert): Deprecate this API.
* libguile/srcprop.c:
* libguile/srcprop.h:
* libguile/read.c (scm_read_sexp): Use the hashq API instead of the
whash API.
* libguile/hashtab.c (set_weak_cdr, scm_hash_fn_set_x): If we have a
weak-value hash table with a previous non-immediate value for a given
key, and we are setting an immediate as the new value, we were not
unregistering the disappearing link. Fixed.
* module/ice-9/psyntax.scm (free-id=?): For identifiers that are
resolved to the toplevel, check that the variables that they would
resolve to are equal, instead of simply checking that the symbolic
identifier names are equal. Allows keywords to be bound, renamed,
exported, excluded, etc.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (chi-when-list): Just match symbolically
instead of lexically, so as not to tie the meaning of eval-when to the
bindings of eval, load, compile, and expand.
* libguile/eval.c (truncate_values): New helper.
(EVAL1): New macro, does an eval then truncates the values.
(eval, prepare_boot_closure_env_for_apply)
(prepare_boot_closure_env_for_eval): Use EVAL1 in appropriate places
to get multiple-values truncation even here in the boot evaluator.
eval.c fixen
* configure.ac: Check for the iconveh values here, instead of relying on
gen-scmconfig to know them. That doesn't work in general because
gen-scmconfig runs on the build machine, not the target machine.
* libguile/Makefile.am (gen-scmconfig.$(OBJEXT)): Revert rule to the
revision before 533d8212.
* libguile/gen-scmconfig.h.in (SCM_I_GSC_ICONVEH_ERROR):
(SCM_I_GSC_ICONVEH_QUESTION_MARK):
(SCM_I_GSC_ICONVEH_ESCAPE_SEQUENCE):
* libguile/gen-scmconfig.c: Use configure-time substitutions to set
SCM_ICONVEH_ERROR_HANDLER et al.
* module/ice-9/boot-9.scm (while): Specify the return value as #f under
normal conditions, #t under (break), and arg... under (break arg...).
* test-suite/tests/syntax.test ("while"): Test.
* doc/ref/api-control.texi (while do): Document.
* module/ice-9/control.scm (reset, shift): Add implementations of these
operators from Wolfgang J Moeller, derived from implementations by
Oleg Kiselyov.
(reset*, shift*): Procedural variants.
* test-suite/tests/control.test ("shift and reset"): Add tests,
originally from Oleg Kiselyov.
* GUILE-VERSION (GUILE_MICRO_VERSION): Increment.
(LIBGUILE_INTERFACE_CURRENT): Increment to account for new C functions
such as `scm_c_public_ref' and `scm_from_latin1_keyword'.
(LIBGUILE_INTERFACE_AGE): Increment.
* test-suite/tests/ports.test ("string ports"): Add for
`test-decoding-error' tests for ill-formed UTF-8 sequences. Thanks
to Mark H Weaver <mhw@netris.org> for pointing this out.
* test-suite/tests/ports.test ("string ports")["%default-port-encoding
is honored"]: Make sure `(port-encoding p)' is as expected.
["peek-char [utf-16]"]: New test.
* test-suite/standalone/test-pthread-create.c (inner_main): New
function.
(main): Call it within `scm_with_guile', instead of using
`scm_init_guile'. This improves portability--e.g.,
`GC_get_stack_base', used by `scm_init_guile', failed on Darwin
up to BDW-GC 7.1alpha4 included (thanks, Mark, for the hint.)
* test-suite/tests/threads.test ("timed locking succeeds if mutex
unlocked within timeout", "timed unlocking returns #t if condition
signaled", "timed joining succeeds if thread exits within timeout"):
Increase the timeout. Reported by Dale P. Smith <dsmich@roadrunner.com>.
* doc/ref/api-data.texi (Conversion to/from C): In descriptions of
scm_to_stringn and scm_to_{latin1,utf8,utf32}, clarify that the
returned length is in units of bytes or code points, not characters.
Also change NULL to @code{NULL} in a few places.
* configure.ac: Add a check for GC_set_start_callback.
* libguile/gc.c (scm_i_gc): If we don't have GC_set_start_callback, run
the before-gc hook manually here.
(scm_init_gc): Otherwise set it as a start callback.
* libguile/hashtab.c (weak_gc_callback, weak_gc_hook)
(weak_gc_finalizer, scm_c_register_weak_gc_callback): Fix to work
either way, with or without GC_set_start_callback.
