* libguile/atomics-internal.h (scm_atomic_subtract_size): New helper.
* libguile/gc.c (scm_gc_register_allocation): Rework to use atomics.
(scm_gc_event_listener_restarting_mutators): Reset the
off_heap_allocation_countdown to the heap size after GC.
(scm_gc_disable, scm_gc_enable): Remove these. Unclear what they mean
exactly! Perhaps if there is a meaning we can look at it later.
(scm_i_gc):
(scm_storage_prehistory):
(scm_init_gc): Update.
* libguile/threads.c (with_guile, scm_without_guile): Use gc_activate /
gc_deactivate API. It's a noop on BDW, but all we lose is a bit of
precision.
(%call-with-new-thread): Remove GC_collect_a_little call, it was
useless.
Oh yeah! They are almost impossible to use correctly as-is, have mostly
disappeared in practice (I am aware of only two users), have the wrong
interface for moving collectors, and current usage has cemented smobs as
conservatively-marked objects. In order to move forward with Whippet,
they have to go!
* libguile/deprecated.h (SCM_SMOB_MARK, SCM_GLOBAL_SMOB_MARK, scm_mark0)
(scm_markcdr, scm_free0, scm_set_smob_mark, scm_gc_mark): Remove these,
leaving defines to indicate that users should talk to guile-devel to
figure out what to do.
* libguile/smob.h: Remove interfaces relating to mark functions.
(scm_new_double_smob, scm_new_smob): Make not inline
* libguile/smob.c: Remove mark functions from here.
(scm_new_smob): Out-of-line-only definition.
(scm_smob_prehistory): Don't create a new GC kind for smobs.
* test-suite/standalone/test-smob-mark-race.c:
* test-suite/standalone/test-smob-mark.c: Remove.
* test-suite/standalone/Makefile.am: Update.
* libguile/symbols.c: Rework the symbol table to be an ephemeron table
instead of a weak set. It is no longer resizeable; getting that to work
will involve some GC cooperation.
* libguile/ephemerons.h:
* libguile/ephemerons.c (scm_c_ephemeron_load, scm_c_ephemeron_push):
New routines.
* libguile/ioext.c (scm_fdes_to_ports): Rework in terms of
scm_c_port_for_each.
* libguile/ports-internal.h (struct scm_t_port): Add pointer to entry on
weak ports list, so that we can cancel it easily.
* libguile/ports.c (release_port): Mark weak ports list entry as dead.
(all_ports_needing_close, for_each_port_needing_close): Rework as
ephemeron chain.
(scm_c_make_port_with_encoding, close_port, scm_c_port_for_each): Adapt
API.
(scm_init_ports): No more weak set.
It was never documented, never used, and uses the gross assoc interface
to doubly-weak tables. Good-bye!
* module/ice-9/hcons.scm: Remove.
* am/bootstrap.am: Remove hcons from build.
* module/ice-9/poe.scm: Extract the one procedure from hcons that poe
uses, which notably doesn't have anything to do with hcons.
* module/language/tree-il.scm (tree-il-src): Always a vector now;
tree-il-srcv is gone. An incompatible change but we are in the
compiler.
(location): For parse-tree-il, make vector locations instead of alists.
* module/language/tree-il/analyze.scm:
* module/language/tree-il/compile-bytecode.scm:
* module/language/tree-il/compile-cps.scm:
* module/language/tree-il/debug.scm:
* module/language/tree-il/letrectify.scm:
* module/language/tree-il/peval.scm:
* module/system/vm/assembler.scm: Update all uses to expect vectors
instead of alists and to use tree-il-src instead of tree-il-srcv.
* module/language/elisp/compile-tree-il.scm (location): Create vectors,
not alists.
* test-suite/tests/compiler.test ("psyntax"): Update syntax-source
expectation.
* module/ice-9/psyntax.scm (source-annotation): Only get source info
from syntax objects.
(strip): Don't attach source info.
(macroexpand): Don't proxy source info in that isn't in a syntax object.
(datum->syntax): Don't proxy source info from source-properties.
* test-suite/tests/compiler.test ("psyntax"):
* test-suite/tests/coverage.test (code):
* test-suite/tests/eval-string.test ("basic"):
* test-suite/tests/syntax.test ("expressions"):
* test-suite/tests/tree-il.test ("warnings"): Update tests that attach
source properties to use read-and-compile, or read-syntax.
* libguile/goops.c (scm_i_define_class_for_vtable)
(create_struct_classes): Use ephemeron hash tables instead of the weak
table API. Add a FIXME about a race.
* libguile/ephemerons.c (scm_from_ephemeron, scm_to_ephemeron):
(scm_from_ephemeron_table, scm_to_ephemeron_table): New interfaces.
(scm_c_ephemeron_table_copy): Rename from
scm_c_ephemeron_hash_table_copy, as it's not specific to hash tables.
* libguile/fluids.h:
* libguile/fluids.c (restore_dynamic_state, save_dynamic_state)
(saved_dynamic_state_ref, fluid_set_x, fluid_ref)
(scm_fluid_ref_star, scm_i_make_initial_dynamic_state): Use ephemeron
hash tables.
This will allow for weak tables to be implemented partly in Scheme.
* module/ice-9/object-properties.scm: New file.
* am/bootstrap.am (SOURCES): Add new file.
* module/ice-9/boot-9.scm:
* module/ice-9/deprecated.scm (make-object-property*): Deprecate
make-object-property in default env and add a shim.
* module/ice-9/buffered-input.scm (ice-9):
* module/language/elisp/boot.el (plist-function):
* module/scripts/frisk.scm (scripts):
* module/web/http.scm (web): Adapt users to import the new module.
* libguile/threads.h: Add join data directly on the thread instead of
using a Scheme-side weak table. It's less complicated and it will let
the weak table implementation use locks in Scheme; otherwise you would
have threads depending on weak tables and vice versa.
* libguile/threads.c (scm_trace_thread, guilify_self_1): Init and mark
the new members.
(thread_join_cond, thread_join_lock, thread_join_results)
(thread_init_joinable_x, thread_set_join_results_x): New accessors.
* module/ice-9/threads.scm (call-with-new-thread, join-thread): Use the
new accessors.
If that's what you want, you need to bring your own weak hash table on a
normal observer.
* module/ice-9/boot-9.scm (module): Remove weak-observers field.
(make-module, make-autoload-interface): Don't pass weak table to
constructor.
(module-observe-weak): Remove.
(module-unobserve, module-call-observers): Remove weak case.
* module/ice-9/deprecated.scm (module-observe-weak): Dispatch to
module-observe.
* test-suite/tests/modules.test ("observers"): Adapt.
The former allows for knowing whether a push succeeded or not, which is
useful for concurrent hash tables. The latter makes ephemerons mutable,
if the embedder wants to use them that way.
* module/ice-9/weak-vector.scm: New implementation, same interface.
* doc/ref/api-memory.texi (Weak vectors): Default weak vector value was
documented as empty list when it was actually unspecified, but #f is
most useful, so we change documentation and code to match.
* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
(DOT_X_FILES):
(DOT_DOC_FILES):
(noinst_HEADERS):
(modinclude_HEADERS):

(record-constructor): Alias record-type-constructor.
(make-module): Require size to be zero. Should fix this with keyword
args :/
(try-load-module): Inline definition of try-module-autoload. Remove
try-module-autoload binding.

eventually.
* module/ice-9/save-stack.scm: Remove deprecation comment.
* module/ice-9/top-repl.scm:
* module/ice-9/threads.scm: Export instead of replace bindings.
* module/language/bytecode.scm: Remove instruction-arity et al.
* module/language/tree-il/analyze.scm: Remove deprecated
unbound-variable-analysis and macro-use-before-definition-analysis.

namespaces are separate.

Remove.
