* module/system/vm/program.scm (program-bindings-as-lambda-list): Handle
the bindings-is-null case too -- not sure how it comes about, though. A
thunk with no let, perhaps.
(write-program): Another default for the name: the source location at
which it was defined.
* libguile/programs.c (program_print): Add some "logic" to stop doing
detailed prints if one print had a nonlocal exit -- preventing
exceptions in backtraces.
* module/system/vm/frame.scm (frame-call-representation)
(frame-program-name): Rename program-name to frame-program-name, and
use the program-name if it is available.
* module/system/vm/program.scm (program-bindings): Return #f if there are
no bindings.
(program-name): New public procedure.
(program-bindings-as-lambda-list, write-program): A more useful writer
for programs.
* libguile/programs.c (scm_bootstrap_programs, program_print): Add a smob
printer for programs, which dispatches to `write-program'.
* libguile/threads.c (on_thread_exit): Add caveat about possible
segfault.
git-archimport-id: lcourtes@laas.fr--2006-libre/guile-core--boehm-gc--0--patch-8
* libguile/gc-malloc.c (scm_gc_malloc): Pass a non-zero size to
`GC_MALLOC ()' when SIZE is zero.
git-archimport-id: lcourtes@laas.fr--2006-libre/guile-core--boehm-gc--0--patch-2
* libguile/gc.c (protected_obj_count): Made `static'.
(scm_heap_size): Mapped to `heap-size' rather than `cell-heap-size'.
(scm_heap_free_size): New.
(scm_heap_total_allocated): New.
(scm_gc_stats): Rewritten. Return the (little) information available
from `libgc'.
(scm_gc_disable): New.
(scm_gc_enable): New.
(scm_storage_prehistory): Don't call `GC_add_roots ()' with
SCM_SYS_PROTECTS. Use `GC_is_visible ()' to check whether
SCM_SYS_PROTECTS is visible.
* libguile/gc.h (scm_gc_enable): New declaration.
(scm_gc_disable): New declaration.
(scm_gc_for_alloc): Removed.
(scm_gc_for_newcell): Removed.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-46
* libguile/symbols.c (lookup_interned_symbol): When a deleted weak pair
is encountered, remove it and update the hashtable's item count. Also,
check the hash table threshold and trigger a rehashing if needed.
(scm_i_c_mem2symbol): Allocate CELL using `scm_weak_car_pair ()' rather
than `scm_cons ()'.
(scm_i_mem2symbol): Likewise.
(scm_symbols_prehistory): Don't invoke `scm_permanent_object ()' for
SYMBOLS.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-44
* libguile/hashtab.c (scm_i_rehash): Don't invoke
`SCM_HASHTABLE_DECREMENT ()' when a weak pair is encountered in the
source bucket.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-43
* libguile/guardians.c (finalize_guarded): While traversing
GUARDIANS_LIST, check for deleted weak-car pairs.
(scm_i_guard): Instantiate GUARDIANS_FOR_OBJ using `scm_weak_car_pair ()'
rather than `scm_cons ()'.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-41
* libguile/hashtab.c (weak_hashtables): Removed.
(SCM_WEAK_CELL_DELETED_P): New macro.
(START_WEAK_BUCKET_FIXUP): Added the HASHFN argument. Invoke
`scm_i_rehash ()' when pairs have been removed.
(END_WEAK_BUCKET_FIXUP): Added the HASHFN argument.
(make_hash_table): Use `SCM_NEWSMOB2 ()' instead of `SCM_NEWSMOB3 ()'
-- last argument used to be WEAK_HASHTABLES.
(scm_i_rehash): Handle weak hash tables.
(to_rehash): Removed.
(scm_internal_hash_fold): Use `SCM_WEAK_CELL_DELETED_P ()' rather than
hand-written equivalent code.
(rehash_after_gc): Removed.
(scm_hashtab_prehistory): Don't add it as an after-gc hook.
* libguile/hashtab.h (SCM_HASHTABLE_NEXT): Removed.
(SCM_HASHTABLE_NEXTLOC): Removed.
(SCM_SET_HASHTABLE_NEXT): Removed.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-38
* libguile/ports.c (register_finalizer_for_port): New.
(finalize_port): New.
(scm_new_port_table_entry): Call `register_finalizer_for_port ()'
before returning the new port.
(scm_ports_prehistory): Use `scm_gc_malloc_pointerless ()' instead of
`scm_gc_malloc ()' when allocating room for SCM_I_PORT_TABLE.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-37
* libguile/__scm.h (SCM_DEBUG): add SCM_DEBUG_MARKING_API
* libguile/gc.h (SCM_SET_GC_MARK): depending on
SCM_DEBUG_MARKING_API crash if someone is touching markbits
outside regular hours.
Rename ensure_marking() to scm_i_ensure_marking().
* libguile/inline.h (scm_double_cell, scm_cell): only set mark bits
for debugging if SCM_DEBUG_MARKING_API is unset
* libguile/gc-mark.c: Issue deprecation warning if we are marking
outside of the GC mark phase.
* libguile/gc-card.c: Include <config.h> and <count-one-bits.h>.
(scm_i_uint_bit_count): Remove.
(scm_i_card_marked_count): Use `count_one_bits_l ()' instead
of `scm_i_uint_bit_count ()'.
* libguile/gc-segment.c: Include <config.h> and <count-one-bits.h>.
(scm_i_heap_segment_marked_count): Use `count_one_bits_l ()' instead
of `scm_i_uint_bit_count ()'.
* libguile/private-gc.h (scm_i_uint_bit_count): Remove.
* libguile/programs.h (struct scm_program):
* libguile/programs.c (scm_c_make_program): Record the current module
when making a program. This replaces the per-late binding recorded
module in the generated code, which should be more efficient, both in
terms of garbage, and in not calling resolve-module.
(program-module): New accessor.
* module/system/vm/program.scm: Add program-module to exports.
* libguile/vm-i-loader.c (link-later): Remove this instruction, since now
the entry in the object table is just a symbol, and can be loaded with
load-symbol.
* libguile/vm-i-system.c (late-variable-ref, late-variable-set): Rework
so as to look up in the module of the current program. The logic could
be condensed quite a bit if scm_module_lookup () knew what to do with
mod==#f.
* module/system/vm/assemble.scm (dump-object!): Dump <vlink-later> just
as load-symbol, as mentioned in the note on link-later.
* module/system/il/ghil.scm: Update comment to reflect the new reality.
* module/system/vm/assemble.scm (make-meta, codegen): Hide the "meta"
information -- the names of the bindings, source info, procedure
properties, etc -- behind a lambda. This way, loading up a program
conses less, because the metadata stays as mmap'd code until it is
needed.
* libguile/vm-i-loader.c (load-program): Adjust load-program to expect
the metadata to be a program.
* module/system/vm/program.scm (program-bindings, program-sources)
(program-properties): Adjust to new meta format.
* libguile/modules.c (module-variable): If module is #f, access the
pre-modules-array. This is so that nested-ref can work before the
module system is booted, I think.
Of course all of these dependency lines during bootstrap are just to
make sure the system can be booted properly, either interpreted or
compiled, so there's no one right way: there are many ways that could
work.
