(Thanks to Gregory Marton for reporting this.)
* tests/hash.test: New "hashx" test supplied by Gregory Marton;
prior to today's fix in libguile/hashtab.c, this caused a
segmentation fault.

hashtable and guardian machinery but call the relevant functions
directly.
* guardians.h, guardians.c, deprecated.h,
deprecated.c (scm_destroy_guardian_x, scm_guardian_greedy_p,
scm_guardian_destroyed_p, scm_guard, scm_get_one_zombie):
Deprecated and moved into deprecated.[ch].

(hashtable_print): Use SCM_HASHTABLE_N_ITEMS instead of
t->n_items.
(scan_weak_hashtables, scm_i_scan_weak_hashtables): Renamed former
to latter. Do not scan the alists themselves, this is done by the
weak vector code now. Just update the element count.
* vectors.h (SCM_I_WVECT_TYPE, SCM_I_WVECT_EXTRA): Renamed former
to latter. The type is now only part of the cell word.

closure can not be stored since it is no longer valid at GC time.

NULL.

non-NULL. Always use a NULL closure.
(scm_hash_fn_create_handle_x): Also rehash when table contains too
few entries.

argument; always use scm_delq_x. The delete_fn function works on
the handle, not the key, and it therefore makes no sense to make
it configurable. Changed all callers.
(scm_hashx_remove_x): Likewise. Also, exported to Scheme.
(scm_hash_clear): Accept plain vectors as hashtables.
(scm_delx_x): Removed.

|
|
(scan_weak_hashtables): Rewrote its use with SCM_HASHTAB_BUCKET
and SCM_SET_HASHTAB_BUCKET.
|
|
(SCM_HASHTABLE_BUCKET, SCM_HASHTABLE_BUCKET_LOC): New. Replaced
all uses of SCM_HASHTABLE_BUCKETS with SCM_HASHTABLE_BUCKET.

print.c, ports.c, mallocs.c, hooks.c, hashtab.c, fports.c,
guardians.c, filesys.c, coop-pthreads.c, continuations.c: Use
scm_uintprint to print unsigned integers, raw heap words, and
adresses, using a cast to scm_t_bits to turn pointers into
integers.

scm_ulong_long2num, scm_num2long_long, scm_num2ulong_long):
Discouraged by moving to discouraged.h and discouraged.c and
reimplementing in terms of scm_from_* and scm_to_*. Changed all uses
to the new scm_from_* and scm_to_* functions.
|
|
SCM_INUM): Deprecated by reenaming them to SCM_I_INUMP, SCM_I_NINUMP
and SCM_I_INUM, respectively and adding deprecated versions to
deprecated.h and deprecated.c. Changed all uses to either use the
SCM_I_ variants or scm_is_*, scm_to_*, or scm_from_*, as appropriate.

SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
fixnum/bignum distinction visible. Changed all uses to scm_to_size_t
or similar.
|
|
SCM_I_MAKINUM and changed all uses.
|
|
SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into "deprecated.h".
Replaced all uses with scm_is_false, scm_is_true, scm_from_bool, and
scm_is_bool, respectively.
