* Reimplement dynamic statesAndy Wingo2016-12-051-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two goals: one, to use less memory per dynamic state in order to allow millions of dynamic states to be allocated in light-weight threading scenarios. The second goal is to prevent dynamic states from being actively mutated in two threads at once. This second goal does mean that dynamic states object that escape into scheme are now copies that won't receive further updates; an incompatible change, but one which we hope doesn't affect anyone. * libguile/cache-internal.h: New file. * libguile/fluids.c (is_dynamic_state, get_dynamic_state) (save_dynamic_state, restore_dynamic_state, add_entry) (copy_value_table): New functions.

(scm_current_dynamic_state): Use make_dynamic_state. (scm_dynwind_current_dynamic_state): Use new accessor. * libguile/fluids.h: Remove internal definitions. Add new struct definition. * libguile/threads.h (scm_i_thread): Use scm_t_dynamic_state for dynamic state. * libguile/threads.c (guilify_self_1, guilify_self_2): (scm_i_init_thread_for_guile, scm_init_guile): (scm_call_with_new_thread): (scm_init_threads, scm_init_threads_default_dynamic_state): Adapt to scm_i_thread change. (scm_i_with_guile, with_guile): Remove "and parent" suffix. (scm_i_reset_fluid): Remove unneeded function. * doc/ref/api-scheduling.texi (Fluids and Dynamic States): Remove scm_make_dynamic_state docs. Update current-dynamic-state docs. * libguile/vm-engine.c (vm_engine): Update fluid-ref and fluid-set! inlined fast paths for dynamic state changes. * libguile/vm.c (vm_error_unbound_fluid): Remove now-unused function. * NEWS: Update. * module/ice-9/deprecated.scm (make-dynamic-state): New definition. * libguile/deprecated.h: * libguile/deprecated.c (scm_make_dynamic_state): Move here. * libguile/__scm.h (scm_t_dynamic_state): New typedef. * libguile/dynstack.h: * libguile/dynstack.c (scm_dynstack_push_fluid): (scm_dynstack_unwind_fluid): Take raw dynstate in these internal functions. * libguile/throw.c (catch): Adapt to dynstack changes.
