(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.
(SCM_I_SET_WVECT_TYPE, SCM_I_SET_WVECT_EXTRA): Likewise.
* init.c (scm_i_init_guile): Do not call scm_weaks_prehistory.
(scm_vector_elements, scm_vector_writable_elements,

(SCM_STRING_CHARS, SCM_STRING_UCHARS, SCM_STRING_LENGTH): Renamed
to SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_LENGTH
respectively. For a short time, the old names are still there as
aliases. Not all uses have been changed yet, but the ones in
strings.c have.
(SCM_STRING_MAX_LEN): Do not hardcode to 24 bits, compute from
SCM_T_BITS_MAX.
(scm_is_string, scm_from_locale_string, scm_from_locale_stringn,

to replace similar code from posix.c, simpos.c, and dynl.c.
(scm_string_append): Use memcpy instead of explicit loop. Do not
use register keyword. Use plain 'char' instead of 'unsigned
char'.
Reimplement using scm_is_false, scm_is_true, scm_is_bool, and
scm_from_bool, respectively.
(SCM_NINUMP): Added.
* tags.h, deprecated.h (SCM_EQ_P): Deprecated by moving it into
deprecated.h. Replaced all uses with scm_is_eq.
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_MIN, SCM_VALIDATE_INUM_MIN_COPY,
SCM_VALIDATE_INUM_MIN_DEF_COPY,SCM_VALIDATE_INUM_DEF,
SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
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_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.
* boolean.h (scm_is_bool): Fix bug in prototype.
(scm_from_bool): The argument is "x" not "f", stupid.
* deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
eval.h to eval.c.
* deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
(SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
renamed to ISYMNUM.
* eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
(scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
Extracted printing of ilocs and isyms to guile internal functions
scm_i_print_iloc, scm_i_print_isym of eval.c.
SCM_DEBUGGINGP:
* debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
single interface that also matches the naming conventions.
Probably scm_debug_mode_p should be part of the private interface
anyway.
* debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
to scm_debug_mode_p.
Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
* eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
(scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
from debug.h to eval.h.
* debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
more, just leave it with setting scm_debug_mode_p, which is
equivalent for practical purposes.
* deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
* gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
* eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
static and renamed it to ceval throughout. Provide a new exported
but deprecated function scm_ceval as a wrapper for backwards
compatibility. The same is done for the deval/scm_deval pair of
functions.
* eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
throughout. Defined CEVAL to ceval or deval, based on compilation
phase.
* eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
to ceval and deval instead of calling *scm_ceval_ptr.
* eval.c (dispatching_eval): New deprecated static function.
* eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
to emulate its old behaviour as closely as possible.
Change the evaluator such that only expressions for which pair? is
true are passed to CEVAL, and such that all other expressions are
evaluated outside of CEVAL:
* eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
expression that is assumed to be memoized already. All but
expressions of the form '(<form> <form> ...)' are evaluated inline
without calling an evaluator.
* eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
expressions of the form '(<form> <form> ...)' inline without
calling an evaluator.
* eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
the special case of unmemoized symbols passed on the top level.
* eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
is known that the expression passed to CEVAL is of the form
'(<form> <form> ...)'. Remove handling of the tc7-objects, since
now it is known that the input expression of CEVAL is a pair.
of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
* numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
deprecated.h.
* configure.in: Checking for __int64 as possible candidate for
the SCM_I_GSC_T_INT64 define.
2003-06-14 Stefan Jahn <stefan@lkcc.org>
* threads.h: Redefined scm_getspecific() and scm_setspecific()
to be functions instead of macros.
* threads.c: Conditionalized inclusion of <sys/time.h> and
<unistd.h>.
(scm_getspecific, scm_setspecific): Made these two function
real part of the API.
* posix.c (s_scm_putenv): Added some code to make a
(putenv "FOO="), i.e. setting an empty string, work also on
Win32 systems. Thanks to Kevin Ryde for the proposal.
SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
generalized it to apply not only to C level functions but also to
scheme level functions.
* debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?,
scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
respectively.
* deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
SCM_IDSTMSK): Deprecated. The macro definitions are moved from
eval.h into eval.c and a copy is placed into deprecated.h.
* eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
into eval.c. This definition was not part of the API in any
officially released version of guile and thus does not need to go
through a phase of deprecation.
scm_s_expression, scm_s_test, scm_s_body, scm_s_bindings,
scm_s_variable, scm_s_clauses, scm_s_formals. In eval.c the
definitions are make static and renamed from scm_s_xxx to s_xxx.
In deprecated.c the original definitions are copied.
* deprecated.h, eval.c, eval: Deprecated SCM_EVALIM2, SCM_EVALIM,
SCM_XEVAL and SCM_XEVALCAR. The macro definitions are moved from
eval.h into eval.c and a copy (slightly modified to work in user
code) is placed into deprecated.h.
* eval.c: Use the local static s_xxx definitions instead of the
scm_s_xxx definitions throughout.
scm_make_subr_with_generic, scm_make_subr_opt,
scm_call_catching_errors, scm_make_smob_type_mfpe, scm_set_smob_mfpe,
scm_strprint_obj, scm_read_0str, scm_eval_0str, SCM_CHARS, SCM_UCHARS,
SCM_LENGTH): Re-added from the release_1_6 branch. Some have been
slightly rewritten. (scm_i_object_chars, scm_i_object_length): New,
to support SCM_CHARS, SCM_UCHARS, and SCM_LENTH.
