* libguile/frames.c: Add compile-time assertions on the layout of
`struct scm_vm_frame'.
(RELOC): Parenthesize and type VAL.
* libguile/frames.h (SCM_FRAME_STRUCT): Write in terms of
`SCM_FRAME_DATA_ADDRESS'.
(SCM_FRAME_DATA_ADDRESS): Parenthesize and type FP.
(SCM_FRAME_SET_DYNAMIC_LINK): Write in terms of
`SCM_FRAME_DYNAMIC_LINK'.
* libguile/vm.c (RELOC): Parenthesize and type SCM_P.
* libguile/symbols.c (scm_gensym): Make the gensym counter a 128-bit
thread-local, initialized to a random number upon the first call to
`gensym' within a given thread. This counter is rendered as a 22 byte
suffix of mostly base64 digits.
* libguile/threads.h (scm_i_thread): Add a thread-local gensym_counter.
* libguile/threads.c (guilify_self_1): Initialize gensym_counter to NULL.
Based on a patch by Julian Graham <julian@member.fsf.org>
* libguile/values.c, libguile/values.h (scm_c_value_ref): New function.
* doc/ref/api-control.texi (Multiple Values): Add documentation.
* test-suite/standalone/test-scm-values.c: New test program.
* test-suite/standalone/Makefile.am: Add test-scm-values test.
* m4/gnulib-cache.m4: Use `dirfd'.
* libguile/filesys.c: Include Gnulib's <dirent.h> directly.
(dirfd): Remove. Suggested by Bruno Haible <bruno@clisp.org>.
* libguile/strings.c (scm_i_substring, scm_i_substring_read_only,
scm_i_substring_shared): When asked to create an empty substring,
return a freshly allocated null string. Previously, an empty
substring needlessly held a reference to the original stringbuf.
* libguile/strings.c (scm_from_stringn): Avoid calling
`u32_conv_from_encoding' on the null string, by using the same
fast-path code used if (encoding == NULL). This is an optimization,
and also avoids any possible encoding errors.
* libguile/strings.c (scm_from_stringn): Always return a freshly
allocated string from scm_from_stringn, even when asked to construct
the null string, in accordance with the R5RS. Previously, we
optimized the null string case by returning a reference to a global
null string object (scm_nullstr).
* libguile/i18n.c (scm_i_locale_free): Remove.
(smob_locale_free): Define only when USE_GNU_LOCALE_API.
(scm_make_locale)[!USE_GNU_LOCALE_API]: Allocate
`c_locale->locale_name' with `scm_gc_strdup', not `malloc'.
* libguile/tags.h (scm_tc7_array): Allocate a tag for arrays.
* libguile/arrays.h (SCM_I_ARRAYP): Change to use scm_tc7_array. The
previous definition was not externally usable because scm_i_tc16_array
was internal.
(scm_i_print_array): Declare, though internally.
* libguile/arrays.c (scm_i_make_array): Use scm_cell with the tc7
instead of NEWSMOB.
(scm_i_print_array): Make not static.
(SCM_ARRAY_IMPLEMENTATION): Adapt.
(scm_init_arrays): Remove array smob declaration.
* libguile/eq.c (scm_equal_p): Refactor to put the string, pointer, and
bytevector cases in the switch. Add a case for arrays.
* libguile/goops.c: Add <array> declarations.
* libguile/print.c (iprin1): Call scm_i_print_array as needed.
* libguile/evalext.c (scm_self_evaluating_p): Add a case for arrays.
* libguile/load.c (scm_primitive_load): Return the values yielded from
evaluating the last expression in the file.
* test-suite/tests/load.test ("return value of `load'"): Add tests.
* libguile/srfi-13.c (scm_string_copy_x, scm_substring_fill_x,
string_upcase_x, string_downcase_x, string_titlecase_x,
string_reverse_x, scm_string_xcopy_x): Avoid calling
`scm_i_string_start_writing' if the range of indices to be modified is
empty. This avoids the error that would be raised by
`scm_i_string_start_writing' if the string is not mutable.
Thanks to Bruce Korb <bkorb@gnu.org> for reporting this problem
and suggesting the fix.
* libguile/deprecated.h: Mark scm_immutable_cell and
scm_immutable_double_cell as being SCM_DEPRECATED, not SCM_API.
Deprecate SCM_ASRTGO.
* libguile/deprecated.c (scm_i_deprecated_asrtgo): New support
procedure.
* doc/ref/api-control.texi (Handling Errors): Remove ASRTGO docs.
* libguile/strings.c (scm_i_is_narrow_string, scm_i_try_narrow_string,
scm_i_string_set_x): Check to see if the provided string is a
mutation-sharing substring, and do the right thing in that case.
Previously, if such a string was passed to these functions, they would
behave very badly: while trying to fetch and/or mutate the cell
containing the stringbuf, they were actually fetching or mutating the
cell containing the original shared string. That's because
mutation-sharing substrings store the original string in CELL_1,
whereas all other strings store the stringbuf there.
* libguile/strings.c (scm_init_strings): Make scm_nullstr mutable. It
is still usable as a common object, because of course it contains no
characters to mutate anyway. It is returned by several procedures
that are specified to return mutable strings, and string mutators
raise errors when passed an immutable string, even if it is the null
string.
* libguile/objcodes.c (make_objcode_from_file): Close the mmap'd file,
so that we don't leak the descriptor. I was previously under the
mistaken impression that closing the fd unmapped the memory, which is
not the case. Thanks to Cedric Cellier for the tip!
* libguile/procprop.c
(scm_set_procedure_properties_x)[SCM_ENABLE_DEPRECATED == 1]: Pass arguments
to `scm_assq' in the right order, and check its return value with
`scm_is_true'. Reported by Mike Gran <spk121@yahoo.com>.
* libguile/generalized-vectors.c (scm_c_generalized_vector_ref):
(scm_c_generalized_vector_set_x): Fix for the case in which base was
not 1, lbnd was not 0, or inc was not 1.
* test-suite/tests/arrays.test (array): Add a test. Thanks to Daniel
Llorens for the report.
* libguile/threads.c (scm_ia64_register_backing_store_base)
(scm_ia64_ar_bsp): Provide implementation of these itanium helpers on
freebsd. Thanks to Jim Pryor.
* configure.ac: Check for pthread_np.h and pthread_attr_get_np. Patch
by Jim Pryor.
* libguile/threads.c (get_thread_stack_base): Provide an implementation
for FreeBSD.
This is a temporary workaround for the 2.0 stable series. The next
stable series should have an implicit `setlocale (LC_ALL, "")' call,
which will make this unnecessary.
* libguile/feature.c (progargs_fluid): Rename to...
(scm_program_arguments_fluid): ... this. Update users.
* libguile/feature.h (scm_program_arguments_fluid): New internal
declaration.
* libguile/init.c (invoke_main_func): Call
`scm_i_set_boot_program_arguments' instead of
`scm_set_program_arguments'.
* libguile/script.c (locale_arguments_to_string_list,
scm_i_set_boot_program_arguments): New functions.
(scm_compile_shell_switches): Use `locale_arguments_to_string_list'.
* libguile/script.h (scm_i_set_boot_program_arguments): New internal
declaration.
* test-suite/standalone/Makefile.am (check_SCRIPTS, TESTS): Add
`test-command-line-encoding'.
* test-suite/standalone/test-command-line-encoding: New file.
* libguile/foreign.c: Use `alignof_type' instead of `alignof'; the
latter was removed from Gnulib's <alignof.h> in
408e170e3ae81f73fb65686c5834693d89a96594 (Nov. 1 2011).
* libguile/vm-i-scheme.c: Likewise.
* libguile/ports.c (scm_init_ports): Export the port fluids to Scheme,
temporarily.
* module/ice-9/boot-9.scm (fluid->parameter): Turn `current-input-port'
et al into srfi-39 parameters, backed by the exported fluids, then
remove the fluids from the guile module.
(%cond-expand-features): Add srfi-39.
* module/srfi/srfi-39.scm: Re-export features from boot-9.
* test-suite/tests/parameters.test: Add tests.
* configure.ac: Add checks for GC_gcollect_and_unmap and
GC_get_unmapped_bytes.
* libguile/gc-malloc.c (scm_realloc): GC_gcollect() if we don't have
GC_gcollect_and_unmap.
* libguile/gc.c (GC_get_heap_usage_safe): Likewise, don't
GC_get_unmapped_bytes if the function doesn't exist.
