* 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.
* 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.
* libguile/hashtab.c (weak_gc_callback)
(scm_c_register_weak_gc_callback): Change implementation to use the
before-gc C hook instead of the after-gc finalizers.
* libguile/gc.c (run_before_gc_c_hook, scm_storage_prehistory)
(after_gc_async_thunk, queue_after_gc_hook, scm_init_gc): Instead of
playing our finalizer trick, connect to the GC start callback, and use
it to queue an async after-gc-hook. Seems to fix the after-gc-hook on
non-threaded builds. Though this does re-enable the before-gc C hook,
we don't wire up the Scheme hook because we're in the alloc lock; and
indeed, a before-GC scheme hook isn't a great idea...
* doc/ref/api-evaluation.texi (Compilation): Add discussion of
--fresh-auto-compile.
* doc/ref/scheme-scripts.texi (Invoking Guile): Add --fresh-auto-compile
option.
* NEWS: Add entry.
* libguile/load.c: Define %fresh-auto-compile.
(scm_primitive_load_path): Use it here.
(scm_init_load_should_auto_compile): Init from GUILE_AUTO_COMPILE env
var, with a value of "fresh".
* module/ice-9/boot-9.scm (load-in-vicinity): Auto-compilation cache is
stale if %fresh-auto-compile is true.
* module/ice-9/command-line.scm (compile-shell-switches): Parse out
--fresh-auto-compile.
