3            * hooks.c (scm_c_hook_add): Fixed bug in append mode.
4    
5            The following changes introduce the use of resizable hash tables
6            throughout Guile.  It also renames the old *-hash-table* functions
7            to *-alist-vector* and places them, together with the rest of the
8            weak vector support, in the module (ice-9 weak-vector).  We should
9            probably introduce a new, better, API for weak references, for
10            example "weak pairs" a la MIT-Scheme.  (In Chez scheme, they even
11            look like and are used like ordinary pairs.)
12    
13            * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
14            leaf_environment_fold, obarray_remove_all): Use hashtable
15            accessors.
16    
17            * gc.c (scm_init_storage): Moved hook initialization to
18            scm_storage_prehistory.
19            (scm_storage_prehistory): New function.
20            (scm_igc): Added commentary about placement of
21            scm_after_sweep_c_hook.
22    
23            * gc-mark.c (scm_mark_all): Use hashtable accessors.
24            (scm_gc_mark_dependencies): Use SCM_WVECT_WEAK_KEY_P and
25            SCM_WVECT_WEAK_VALUE_P.
26    
27            * hashtab.c, hashtab.h (scm_hash_for_each, scm_hash_map): New
28            functions.
29            (scm_vector_to_hash_table, scm_c_make_resizing_hash_table):
30            Removed.
31            (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
32            scm_make_doubly_weak_hash_table): Moved here from weaks.c.
33    
34            * init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
35            calls to scm_storage_prehistory and scm_hashtab_prehistory.
36    
37            * modules.c (module-reverse-lookup): Use hashtable accessors.
38    
39            * symbols.c, symbols.h (scm_i_hash_symbol): New function.
40    
41            * weaks.c, weaks.h (scm_make_weak_key_alist_vector,
42            scm_make_weak_value_alist_vector,
43            scm_make_doubly_weak_alist_vector): New functions.
44    
45            * weaks.c (scm_init_weaks_builtins): New function.
46    
47            * weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
48            SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
49            SCM_WVECT_NOSCAN_P): New macros.
50    
51            * weaks.c (scm_scan_weak_vectors):  Use SCM_WVECT_WEAK_KEY_P
52            and SCM_WVECT_WEAK_VALUE_P.
53    
54            * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
55            allocate_weak_vector and exported.
