* libguile/finalizers.c: New excitement! We'll be running finalizers
asynchronously, from asyncs. This will make it safer to allocate
while holding a mutex.
(GC_set_finalizer_notifier): Add back-compat shim.
* libguile/init.c (scm_i_init_guile): Init the async finalizer mechanism
during boot.
* libguile/gc.c (scm_storage_prehistory): Tell libgc we'll be finalizing
on demand.
(scm_gc): Explicitly run finalizers here.
* libguile/threads.c (guilify_self_2): Run finalizers here if
queue_finalizer_async happened to run during guilify_self_1.
* configure.ac: Add check for GC_set_finalizer_notifier.
* configure.ac: Remove checks for <langinfo.h> and <nl_types.h>, and
`nl_langinfo'.
* libguile/i18n.c: Remove #ifdefs for HAVE_LANGINFO_H, HAVE_NL_TYPES_H,
HAVE_NL_ITEM, and HAVE_LANGINFO_CODESET.
(SCM_VALIDATE_OPTIONAL_LOCALE_COPY): Use `SCM_UNBNDP'.
* m4/gnulib-cache.m4 (gl_MODULES): Add `nl_langinfo'.
* module/ice-9/i18n.scm (define-vector-langinfo-mapping): Remove
`defaults' parameter; assume (provided? 'nl-langinfo) is always true.
Update users accordingly.
(define-simple-langinfo-mapping): Likewise.
(define-monetary-langinfo-mapping): Likewise, but do not assume
LOCAL-ITEM and INTL-ITEM are always defined.
This should help with regex portability, as reported in
<http://bugs.gnu.org/10684> for Darwin 8.11.
* m4/gnulib-cache.m4 (gl_MODULES): Add `regex'.
* configure.ac: Remove header checks for regex.h, rxposix.h, and
rx/rxposix.h. Remove check for the `regcomp' function. Remove
definition of `HAVE_REGCOMP'. Define `ENABLE_REGEX'.
* libguile/init.c: Check for `ENABLE_REGEX' instead of `HAVE_REGCOMP'.
* libguile/regex-posix.c: Always include <regex.h>. Remove #ifdefs for
rxposix.h and co.
* 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.
* 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.
* configure.ac: Check for GC_get_free_space_divisor.
* libguile/gc.c (GC_get_free_space_divisor): Define an implementation,
if needed.
(accumulate_gc_timer): Fix indentation.
(get_image_size): New terrible hack. Needs implementations on other
platforms.
(adjust_gc_frequency): Attempt to adjust the GC frequency based on
process image growth. Needs more comments.
(scm_init_gc): Add the adjust_gc_frequency to the after_gc_c_hook.
* configure.ac: Add a check for GC_get_suspend_signal().
* libguile/scmsigs.c (GC_get_suspend_signal): Define a fallback
implementation if one isn't available.
(signal_delivery_thread): Unmask the suspend signal so that GC can
stop the world. Fixes test-pthread-create on libgc 7.1 and earlier.
Thanks to Frank Terbeck <ft@bewatermyfriend.org> for the report.
* configure.ac: Remove code that determines the values of the `iconveh_'
constants. Use `GUILE_UNISTRING_ICONVEH_VALUES'. instead.
* acinclude.m4 (GUILE_UNISTRING_CONSTANT,
GUILE_UNISTRING_ICONVEH_VALUES): New macros.
* acinclude.m4 (gl_CLOCK_TIME):
* configure.ac: Locally include gl_CLOCK_TIME. To be fixed properly
when gnulib updates their license to reflect the actual BSD state of
things.
* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_LDFLAGS):
Add -lrt for clock_gettime, if needed.
* meta/guile-2.0-uninstalled.pc.in:
* meta/guile-2.0.pc.in: Likewise, in Libs.private.
* 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.
* 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.
* configure.ac: Check for <sched.h>.
* libguile/posix.c [HAVE_SCHED_H]: Include <sched.h>, for
`sched_setaffinity' & co.
Reported by Marco Maggi <marco.maggi-ipsu@poste.it>.
* configure.ac: Check for pthread_sigmask.
* libguile/gen-scmconfig.c: Create SCM_HAVE_GC_PTHREAD_SIGMASK.
* libguile/pthread-threads.h (scm_i_pthread_sigmask): Only redirect to
GC_pthread_sigmask if GC_pthread_sigmask is present.
* configure.ac: Check for sys/mman.h.
* libguile/objcodes.c (verify_cookie): Factor cookie verification out to
a helper function.
(make_objcode_from_file): Rename from make_objcode_by_mmap. If mmap
is unavailable, just read(2) to a bytevector.
This is not present in earlier versions of BDW-GC
* configure.ac: check for GC_allow_register_threads
* libguile/threads.c (scm_i_init_thread_for_guile): Only call
GC_allow_register_threads if it is present.
* configure.ac: Check for GC_pthread_exit and GC_pthread_cancel.
* libguile/gen-scmconfig.c: Write HAVE_GC_PTHREAD_CANCEL and
HAVE_GC_PTHREAD_EXIT into scmconfig.h.
* libguile/pthread-threads.h (scm_i_pthread_exit, scm_i_pthread_cancel):
Only redefine to their GC_pthread_* variants if we have those
functions, which is not the case in libgc < 7.2.
