* libguile/numbers.c (scm_i_big2dbl_2exp): New static function.
(scm_i_big2dbl): Reimplement in terms of 'scm_i_big2dbl_2exp',
with proper rounding.
* test-suite/tests/numbers.test ("exact->inexact"): Add tests.
* libguile/numbers.c (left_shift_exact_integer,
floor_right_shift_exact_integer, round_right_shift_exact_integer): New
static functions.
(scm_round_ash): New procedure.
(scm_ash): Reimplement in terms of 'left_shift_exact_integer' and
'floor_right_shift_exact_integer'.
* libguile/numbers.h: Add prototype for scm_round_ash. Rename the
second argument of 'scm_ash' from 'cnt' to 'count'.
* test-suite/tests/numbers.test (round-ash, ash): Add new unified
testing framework for 'ash' and 'round-ash'. Previously, the tests
for 'ash' were not very comprehensive; for example, they did not
include a single test where the number to be shifted was a bignum.
* doc/ref/api-data.texi (Bitwise Operations): Add documentation for
'round-ash'. Improve documentation for `ash'.
* libguile/posix.c (scm_execl, scm_execlp, scm_execle)
(scm_open_process): Remove casts for ancient mingw.
(scm_utime): If we fall back to utime, assert that flags is 0.
(scm_getlogin): Rely on gnulib.
* libguile/iselect.h: If we do not have sys/select.h, don't provide
scm_std_select, SELECT_TYPE, FD_SET, FD_ZERO, FD_ISSET, or FD_CLR.
Guile should not be setting these macros in public API. This is an
incompatible change on mingw, but oh well.
* libguile/threads.c: Rely on gnulib's select, and use that to implement
scm_std_select.
* libguile/deprecated.h:
* libguile/deprecated.c: Only provide scm_internal_select if we have
sys/select.h.
* libguile/posix.c: Reorder includes to fix mingw include-order
problem. Remove ttyname shims; gnulib is the place to fix that.
Remove winsock2 include, as gnulib seems to handle that OK. Rely on
the new pipe-posix gnulib module. Don't bother shimming getlogin, etc
on mingw; gnulib is the place for shims.
* libguile/fports.c: Reorder includes to put system includes first;
fixes windows/winsock2 include error problem. Rely on Gnulib's
select module.
(fport_input_waiting): Use select instead of scm_std_select.
* configure.ac (alarm): Check for decl.
* libguile/scmsigs.c: Reorder includes to put system includes first.
Fixes include order on mingw. Remove #define for alarm, as we will
use HAVE_DECL_ALARM. Remove #defines for sleep and usleep, as they
are not used.
(scm_alarm): Only define if HAVE_DECL_ALARM.
* libguile/socket.c (scm_init_socket): Remove mingw-specific code.
* libguile/fports.c: Remove ftruncate redefine; mingw is fine.
(scm_i_fdes_to_port): If we have no F_GETFL, just do an fstat. The
right place for an F_GETFL replacement would be in gnulib.
(fport_input_waiting): Remove an outdated comment.
* libguile/error.c (SCM_I_STRERROR, SCM_I_ERRNO): Remove, replacing uses
with strerror and errno.
* libguile/win32-socket.c:
* libguile/win32-socket.h: Remove. Mingw has suitable replacements.
* configure.ac:
* libguile/Makefile.am (EXTRA_libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
(noinst_HEADERS): Update for win32-socket removal.
* libguile/win32-socket.h:
* libguile/win32-socket.c (getservent, endservent, setservent)
(getprotoent, endprotoent, setprotoent): Remove mingw32 wrappers.
Their place is in gnulib, if anywhere.
Fixes <http://bugs.gnu.org/11887>.
* libguile/numbers.c (mem2ureal): New argument 'allow_inf_or_nan'.
Accept infinities and NaNs only if 'allow_inf_or_nan' is true and "#e"
is not present. Check for "inf.0" or "nan." case-insensitively. Do
not accept rationals with zero divisors.
(mem2complex): Pass new 'allow_inf_or_nan' argument to 'mem2ureal',
which is set if and only if a explicit sign was present.
* test-suite/tests/numbers.test ("string->number"): Add tests.
* libguile/vm.c (initialize_default_stack_size): New helper.
(scm_bootstrap_vm): Call initialize_default_stack_size.
* doc/ref/guile-invoke.texi (Environment Variables): Add docs.
Based on a patch by Stefan Israelsson Tampe.
* libguile/struct.h (SCM_VTABLE_FLAG_SIMPLE, SCM_VTABLE_FLAG_SIMPLE_RW):
* libguile/struct.c (set_vtable_layout_flags): Vtable whose layouts
include a tail array are not simple. Fixes bug 12808.
Reported by Jan Schukat <shookie@email.de>.
Partly fixes <http://bugs.gnu.org/13848>.
* libguile/__scm.h (SCM_LONG_BIT)[!defined LONG_BIT]: Use
SCM_SIZEOF_LONG since `sizeof' cannot be used in #if directives as
found in numbers.c.
* libguile/debug.c (scm_local_eval):
libguile/ports.c (scm_current_warning_port):
libguile/strports.c (scm_eval_string_in_module): Perform
lazy-initialization while holding a mutex. Use SCM_UNDEFINED as the
uninitialized value. Use 'scm_c_*_variable'.
* doc/ref/api-modules.texi (Accessing Modules from C): Fix
'my_eval_string' example to be thread-safe.
Fixes <http://bugs.gnu.org/13611>.
Reported by Mike Gran <spk121@yahoo.com>.
* libguile/smob.c (current_mark_stack_pointer,
current_mark_stack_limit): New variables.
(smob_mark): Use CURRENT_MARK_STACK_POINTER and
CURRENT_MARK_STACK_LIMIT instead of the same-named fields of
`SCM_I_CURRENT_THREAD'.
(scm_gc_mark): Likewise.
(scm_smob_prehistory): Initialize CURRENT_MARK_STACK_LIMIT and
CURRENT_MARK_STACK_POINTER.
* libguile/threads.h (scm_i_thread): Add comment that
`current_mark_stack_ptr' and `current_mark_stack_limit' are no longer
used.
* configure.ac: Check for `GC_set_all_interior_pointers',
`GC_get_gc_no', and `GC_set_java_finalization'.
* libguile/gc.c (scm_gc_stats)[HAVE_GC_GET_GC_NO]: Use `GC_get_gc_no'.
(scm_storage_prehistory)[HAVE_GC_SET_ALL_INTERIOR_POINTERS]: Use
`GC_set_all_interior_pointers'.
* libguile/guardians.c (scm_init_guardians)[HAVE_GC_SET_JAVA_FINALIZATION]:
Use `GC_set_java_finalization'.
Based on a patch by David Kastrup <dak@gnu.org>.
Fixes <http://bugs.gnu.org/13843>.
* libguile/fluids.c (scm_i_make_with_fluids): Reverse direction of inner
loop that checks for duplicates, to properly handle more than two
bindings to the same fluid.
Based on a patch by David Kastrup <dak@gnu.org>.
Fixes <http://bugs.gnu.org/13838>.
* libguile/fluids.c (scm_i_make_with_fluids): Remove the duplicate
binding instead of the last binding.
* test-suite/tests/fluids.test: Add test, and fix existing duplicate
tests.
* THANKS: Thanks David Kastrup.
* libguile/foreign.c (OBJCODE_HEADER, META_HEADER, META): Change these
into higher-order macros.
(GEN_CODE): New higher-order macro based on 'CODE'.
(M_STATIC, M_DYNAMIC): New macros.
(CODE): Reimplement using 'GEN_CODE' and 'M_STATIC'.
(make_objcode_trampoline): New static function.
(large_objcode_trampolines, large_objcode_trampolines_mutex): New
static variables.
(get_objcode_trampoline): New static function.
(cif_to_procedure): Use 'get_objcode_trampoline'.
* test-suite/standalone/test-ffi-lib.c (test_ffi_sum_many):
New function.
* test-suite/standalone/test-ffi: Add test.
* libguile/random.c (random_state_of_last_resort): Simplify optional
inclusion of PID in the random state. Clarify in the comments that
the PID is only included where scm_getpid is present.
* doc/ref/api-data.texi (Random): Clarify that
'random-state-from-platform' includes the PID in the random state only
if scm_getpid is present.
* libguile/filesys.c (is_file_name_separator): New helper, as in
load.c.
(scm_dirname, scm_basename, scm_i_relativize_path): Use
is_file_name_separator.
* libguile/load.c (is_file_name_separator, is_drive_letter):
(is_absolute_file_name): New helpers, like the ones in boot-9.
Perhaps we should just define them in C.
(search_path, scm_try_auto_compile, canonical_suffix): Rewrite using
the new helpers.
