* libguile/threads.c (fat_mutex_lock): In the `m->level == 0' case,
release M's lock before taking T's `admin_mutex'.
|
|
* libguile/threads.c (do_thread_exit): Remove needless spawn of the
signal delivery thread.
|
|
* 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.

|
|
* libguile/strings.c (scm_i_allocate_string_pointers): Encode strings
using the current locale. Previously, Latin-1 was used. Indirectly,
this affects the encoding of strings in `system*', `execl', `execlp',
`execle', `environ', and `dynamic-args-call'.

interpreted according to the current locale encoding.

* configure.ac: Look for ln -s. Write out `guild' instead of
`guile-tools'.
* meta/Makefile.am (install-data-hook): Link the installed `guild' to
the backward-compatible `guile-tools' name.
(bin_SCRIPTS, EXTRA_DIST): Fix up for guild change.
* meta/guild.in: Moved here from `guile-tools.in'.

* libguile/_scm.h (SCM_OBJCODE_ENDIANNESS_OFFSET):
(SCM_OBJCODE_WORD_SIZE_OFFSET): New defines.
* libguile/objcodes.c (scm_write_objcode): Use target-endianness and
target-word-size when writing the objcode cookie.
|
|
|
|
* libguile/hashtab.c (scm_internal_hash_fold): Don't try to unlink
deleted weak pairs. Our previous code was buggy (`prev' should have
only been updated in the case of a successful traversal), but more
than that, we're not in the alloc lock.
Thanks very much to Michael Wells for the report, and the debugging!
|
|
* libguile/r6rs-ports.c (tp_flush): Only operate on the underlying port
when it is open.
|
|
* libguile/pthread-threads.h: As an experiment, just define
scm_i_pthread_create et al to their pthread_* functions, instead of
the GC_ ones. It seems sufficient, given that all uses of Guile have
to go through scm_with_guile anyway... Passes tests on my machine.
Committing to give buildbots a go at it.
|
|
|
|
* libguile/scmsigs.c (read_signal_pipe_data, signal_delivery_thread):
Leave guile when reading from the signal pipe. Hopefully that lets GC
know not to wake up this thread.
|
|
* libguile/smob.h (scm_new_smob, scm_new_double_smob): New constructors,
which do what SCM_NEWSMOB / SCM_NEWSMOB3 had done, but with inline
functions instead of macros. They also bail to scm_i_new_smob /
scm_i_new_double_smob in either the mark or the free case, so that the
inline definition doesn't reference other internal details like libgc
stuff.
(SCM_SMOB_TYPE_MASK et al): Move definitions up so the new_smob see
them as already being declared.
(SCM_NEWSMOB, SCM_RETURN_NEWSMOB, SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2):
(SCM_NEWSMOB3, SCM_RETURN_NEWSMOB3): Reimplement in terms of the new
inline functions.
(scm_i_finalize_smob): Remove declaration, as it's no longer needed or
used.
Remove now-unneeded bdw-gc include.
* libguile/smob.c (finalize_smob): Rename from scm_i_finalize_smob, and
make static.
(scm_i_new_smob, scm_i_new_double_smob): Slow-path allocators.
* libguile/inline.c: Include smob.h, so as to reify scm_new_smob and
scm_new_double_smob.
|
|
* libguile/inline.h:
* libguile/gc.h (scm_cell, scm_double_cell, scm_words): Move
declarations and definitions back here, from inline.h. It's more
natural.
* libguile/inline.c: Include gc.h as well.
|
|
* libguile/__scm.h (SCM_C_EXTERN_INLINE): Move this definition here,
from inline.h. We'd like to support inline function definitions in
more header files: not just inline.h.
(SCM_CAN_INLINE, SCM_INLINE, SCM_INLINE_IMPLEMENTATION): New
definitions.
* libguile/gc.h (SCM_GC_MALLOC, SCM_GC_MALLOC_POINTERLESS): Define these
wrappers, which redirect to the GC_MALLOC macros when building Guile,
and the scm_gc_malloc functions otherwise. A step towards getting
BDW-GC out of Guile's API.
* libguile/inline.h: Simplify, using SCM_INLINE,
SCM_INLINE_IMPLEMENTATION, and SCM_IMPLEMENT_INLINES. Also use the
new SCM_GC_MALLOC macros.
|
|
|
|
* libguile/inline.h:
* libguile/gc.c: Remove declaration and definition of unused
"scm_newcell_count" and "scm_newcell2_count". Since SCM_INTERNAL is
"extern", these symbols were not externally visible anyway, at least
under Linux or Windows.
|
|
* libguile/inline.h:
* libguile/deprecated.h:
* libguile/deprecated.c (scm_immutable_cell, scm_immutable_double_cell):
Deprecate these, as the GC_STUBBORN API doesn't do anything any more.
* libguile/strings.c (scm_i_c_make_symbol): Change the one use of
scm_immutable_double_cell to scm_double_cell.

Conflicts:
libguile/procprop.c
|
|
* libguile/goops.c (scm_i_define_class_for_vtable): Lock around
additions to the vtable_class_map. Use is unlocked though; solving
GOOPS parallel-initialization would be a good thing.
|
|
* libguile/srcprop.c: Add a lock around scm_source_whash, and use it.
|
|
* libguile/srcprop.h: Remove internal scm_source_whash declaration.
* libguile/srcprop.c (scm_i_set_source_properties_x)
(scm_i_has_source_properties): New helpers.
(scm_source_whash): Make static.
* libguile/read.c (scm_read_sexp): Remove register declarations here;
let's trust the compiler. Remove code to incrementally build up a
copy; instead let's let scm_i_set_source_properties_x handle copying
the expression if needed.
(scm_read_quote, scm_read_syntax): Use scm_i_set_source_properties_x.
(recsexpr): Remove this helper from 1996.
(scm_read_sharp_extension): Instead of trying to recursively label
sharp-read subforms with source properties, just label the outside
form and rely on the macro-expander to propagate it down.
|
|
* libguile/smob.c (scm_i_smob_apply_trampoline): Protect the trampoline
weak map with a mutex.
|
|
* libguile/procprop.c (scm_set_procedure_property_x): Fix a threadsafety
bug pointed out by Ken Raeburn.
|
|
* libguile/symbols.c (symbols_lock): Rename from intern_lock.
(lookup_interned_symbol, lookup_interned_latin1_symbol): Instead of
faith-based programming, just use the mutex. Though I haven't seen
this break, Ken is right!
|
|
* libguile/threads.c (lock_mutex_return_void, unlock_mutex_return_void):
New static functions that simply call scm_lock_mutex and
scm_unlock_mutex, respectively, but return void instead of SCM.
(scm_dynwind_lock_mutex): Pass unlock_mutex_return_void to
scm_dynwind_unwind_handler_with_scm, and lock_mutex_return_void to
scm_dynwind_rewind_handler_with_scm. Previously, we passed
scm_unlock_mutex and scm_lock_mutex (which return SCM), but the
scm_dynwind_* functions expect pointers to functions which return
void. When SCM is of type union, this changes the calling conventions
of the functions on some platforms (e.g. GCC 4.5.2 and 4.5.3 on x86).

* libguile/threads.c (lock_mutex_return_void, unlock_mutex_return_void):

scm_unlock_mutex, respectively, but return void instead of SCM.
(scm_dynwind_lock_mutex): Pass unlock_mutex_return_void to
scm_dynwind_unwind_handler_with_scm, and lock_mutex_return_void to

implementation of _POSIX_CPUTIME.
|
|
* libguile/filesys.c (fstat_Win32) [__MINGW32__]: Apparently there is no
_S_IFSOCK on mingw32. Thanks to Volker Grabsch for the report.
|
|
* libguile/Makefile.am (gen-scmconfig.$(OBJEXT)): Fix
cross-compilation. Thanks to Volker Grabsch for the report!
|
|
* libguile/__scm.h: Remove unused SCM_EXIT_SUCCESS and SCM_EXIT_FAILURE
definitions.
|
|
* libguile/threads.c (scm_init_guile):
* libguile/throw.c (scm_exit_status): Use EXIT_SUCCESS and EXIT_FAILURE
instead of 0 and 1.
