2001-05-21  Marius Vollmer  <mvo@zagadka.ping.de>

        * symbols.c (scm_mem2symbol): Re-introduce indirect cell.  It is
        needed for weak-key hashtables.

        * procs.c (scm_make_subr_with_generic): Add missing last argument
        in call to scm_c_define_gsubr_with_generic.  Thanks to Ariel Rios.

        * eval.c: Use SCM_EQ_P instead of `==' or `!=' in certain
        places. (scm_c_improper_memq): Return 1 instead of SCM_BOOL_T.

        * eval.h (SCM_EVALIM2): Use SCM_EQ_P instead of `=='.

2001-05-20  Marius Vollmer  <mvo@zagadka.ping.de>

        * symbols.c (scm_mem2symbol): Call `scm_must_strndup' instead of
        `duplicate_string'.  Do not use an indirect cell, store symbol
        directly in collision list of hash table.
        (duplicate_string): Removed.
        
        * init.c (scm_init_guile_1): Call scm_init_extensions.

        * Makefile.am: Add "extensions.c" and related files in all the
        right places.

        * extensions.h, extension.c: New files.

        * gc.h, gc.c (scm_must_strdup, scm_must_strndup): New.

        * modules.h (scm_system_module_env_p): Move out of deprecated
        section.

        * rw.h (scm_init_rw): Added prototype.

        * gsubr.h, gsubr.c (scm_c_make_gsubr, scm_c_define_gsubr,
        scm_c_make_gsubr_with_generic, scm_c_define_gsubr_with_generic):
        New functions.  They replace scm_make_gsubr and
        scm_make_gsubr_with_generic.  The `make' variants only create the
        gsubr object, while the `define' variants also put it into the
        current module.  Changed all callers.
        (scm_make_gsubr, scm_make_gsubr_with_generic): Deprecated.

        * procs.h, procs.c (scm_c_make_subr, scm_c_define_subr,
        scm_c_make_subr_with_generic, scm_c_define_subr_with_generic): New
        functions.  They replace scm_make_subr, scm_make_subr_opt and
        scm_make_subr_with_generic.  The `make' variants only create the
        subr object, while the `define' variants also put it into the
        current module.  Changed all callers.
        (scm_make_subr, scm_make_subr_opt, scm_make_subr_with_generic):
        Deprecated.

        * eval.c, gc.c, gh_funcs.c, goops.c, macros.c, pairs.c, ramap.c,
        rdelim.c, rw.c, scmsigs.c, snarf.h, values.c: Changed according to
        the comments above.
        
2001-05-19  Neil Jerram  <neil@ossau.uklinux.net>

        * throw.c (scm_lazy_catch): Slight docstring clarification.

2001-05-19  Marius Vollmer  <mvo@zagadka.ping.de>

        * throw.c: Lazy-catch handlers are no longer allowed to return.
        Fixed comments throughout.
        (scm_ithrow): Signal an error when a lazy-catch handler returns.
        Moved actual jump to jmpbuf into if-branch where the jmpbuf is
        recognized as such.

        * version.c (s_scm_micro_version): Fix typo in FUNC_NAME, it
        refered to s_scm_minor_version previously.

        * modules.h, modules.c: Moved around a lot of code so that
        deprecated features appear at the bottom.
        (root_module_lookup_closure, scm_sym_app, scm_sym_modules,
        module_prefix, make_modules_in_var, beautify_user_module_x_var,

        scm_c_call_with_current_module, scm_c_define_module,
        scm_c_use_module, scm_c_export): New.
        (the_root_module): New static variant of scm_the_root_module.  Use
        it everywhere instead of scm_the_root_module.
        
        * fluids.h, fluids.c (scm_internal_with_fluids): Deprecated.
        (scm_c_with_fluids): Renamed from scm_internal_with_fluids.
        (scm_c_with_fluid): New.

        scm_resolve_module.
        
        * init.c (scm_init_guile_1): Call `scm_init_goops' instead of
        `scm_init_oop_goops_goopscore_module'.  Call `scm_init_rdelim' and
        `scm_init_rw' prior to loading the startup files.

        * rdelim.h, rdelim.c: (scm_init_rdelim_builtins): Renamed from
        scm_init_rdelim.  Do not explicitly create/switch modules.

        (scm_init_rdelim): Only register `%init-rdelim-builtins'
        procedure.
        
        * rw.c (scm_init_rw_builtins): Renamed from scm_init_rw.  Do not

        Merged from mvo-vcell-cleanup-1-branch.

        The concept of vcells has been removed from Guile.  With it,
        explicit obarrays and associated operations are gone.  Use
        hashtables instead of obarrays.

        Throughout: use scm_sym2var instead of scm_sym2vcell and treat
        result as variable instead of vcell.  Glocs no longer point to a
        vcell but to a variable.  Use scm_c_define instead of
        scm_sysintern and treat the result as a variable (which it is),
        not a vcell.

        * variable.c, variable.h (SCM_VARVCELL, SCM_UDVARIABLEP,
        SCM_DEFVARIABLEP): Deprecated.

        (scm_make_variable, scm_make_undefined_variable): Do not take name
        hint parameter.
        (scm_variable_ref): Check for SCM_UNDEFINED and throw "unbound"
        error in that case.
        (scm_builtin_variable): Deprecated.

        * symbols.c, symbols.h (scm_sym2vcell, scm_sym2ovcell_soft,
        scm_sym2ovcell, scm_intern_obarray_soft, scm_intern_obarray,
        scm_intern, scm_intern0, scm_sysintern0_no_module_lookup,

        (SCM_VARIABLE, SCM_GLOBAL_VARIABLE, SCM_VARIABLE_INIT,
        SCM_GLOBAL_VARIABLE_INIT): New, as replacement.  Changed all uses.

        * print.c (scm_iprin1): Use scm_module_reverse_lookup instead of
        SCM_GLOC_SYM.

        * evalext.c, filesys.c, fports.c, gdbint.c, gh_data.c, gsubr.c,
        hooks.c, load.c, numbers.c, objects.c, ports.c, posix.c, procs.c,
        ramap.c, random.c, read.c, regex-posix.c, scmsigs.c, script.c,
        socket.c, srcprop.c, stacks.c, stime.c, struct.c, tag.c, throw.c:
        Changed according to the `throughout' comments.

        try_module_autoload, module_make_local_var_x): Tacked on "_var"
        suffix.  Now point to variables instead of vcells.  Updated all
        uses.
        (scm_module_lookup_closure): Deal with the module being SCM_BOOL_F
        and return SCM_BOOL_F in that case.
        (scm_module_transformer): Likewise.
        (sym_module, scm_lookup_closure_module, scm_env_module): New.
        (SCM_F_EVAL_CLOSURE_INTERFACE, SCM_EVAL_CLOSURE_INTERFACE_P): New.

        symbol.

        * keywords.c (s_scm_make_keyword_from_dash_symbol): Use a regular
        hashtable operations to maintain the keywords, not obarray ones.

        * init.c (scm_load_startup_files): Do not call
        scm_post_boot_init_modules.  This is done by
        scm_set_current_module now.
        (scm_init_guile_1): Call scm_modules_prehistory.  Call
        scm_init_variable early on.

        * goops.c (s_scm_sys_goops_loaded): Get
        var_compute_applicable_methods from scm_sym2var, not from a direct
        invocation of scm_goops_lookup_closure.

        * gh_funcs.c (gh_define): Return SCM_UNSPECIFIED instead of vcell.

        * gc.c: Added simple debugging hack to mark phase of GC: When

        * eval.c (scm_lookupcar, scm_lookupcar1): Deal with variables
        instead of with vcells.  Do not overwrite `var' with the result of
        the lookup, use the new `real_var' instead.  Remove `var2' in
        exchange (which was only used with threads).
        (sym_three_question_marks): New.
        (scm_unmemocar): Use `scm_module_reverse_lookup' instead of
        `SCM_GLOC_SYM'.
        (scm_lisp_nil, scm_lisp_t): Directly define as symbols.

        symbol instead.
        (scm_unmemocopy): Removed thoughts about anti-macro interface.
        (scm_eval_args): Use more explicit code in the gloc branch of the
        atrocious struct ambiguity test.  The optimizer will sort this
        out.
        (scm_deval_args): Likewise.
        (SCM_CEVAL): Likewise.  Also, do not use unmemocar, explicitely
        remember the symbol instead.  Added some comments where
        scm_tc3_cons_gloc really exclusively refers to structs.
        (scm_init_eval): Use scm_define to initialize "nil" and "t" to
        scm_lisp_nil and scm_lisp_t, respectively.  Use scm_define instead
        of scm_sysintern in general.

        * dynwind.c (scm_swap_bindings): Use SCM_GLOC_SET_VAL instead of
        explicit magic.

        * debug.c (s_scm_make_gloc): Only allow proper variables, no
        pairs.  Put the variable directly in the gloc.
        (s_scm_gloc_p): Use `scm_tc3_cons_gloc' instead of the magic `1'.
        (scm_init_debug): Use scm_c_define instead scm_sysintern.

        * cpp_cnvt.awk: Emit "scm_c_define" instead of "scm_sysintern".

        instead of a vcell.  Updated all uses.

        * _scm.h: Include "variables.h" and "modules.h" since almost
        everybody needs them now.

        * root.h (scm_symhash, scm_symhash_vars): Removed.
        * gc.c (scm_init_storage): Do not initialize them.

        (scm_init_storage):  Moved initialization of scm_undefineds and
        scm_listofnull to eval.c, initializion of scm_nullstr to
        strings.c, initializion of scm_nullvect to vectors.c.

        * gc.h (SCM_NEWCELL, SCM_NEWCELL2):  Prefer SCM_NULLP over
        SCM_IMP, as in scm_debug_newcell and scm_debug_newcell2.

        * init.c (scm_init_guile_1):  Reordered some initializations and
        added dependcy information comments.

2001-05-09  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

        * procs.c: Increased `scm_subr_table_room' to 800 because Guile now
        has 779 primitives on startup.

2001-05-09  Marius Vollmer  <mvo@zagadka.ping.de>

        * eval.c (scm_i_eval): Copy expression before passing it to
        SCM_XEVAL.  The copy operation was removed unintendedly during my
        change on 2001-03-25.

2001-05-09  Michael Livshin  <mlivshin@bigfoot.com>

        from Matthias Köppe (thanks!):

        * hooks.c: Since hooks don't have a name any more, it is not
        necessary to include objprop.h.

        (hook_print, scm_add_hook_x): Replace SCM_NFALSEP by !SCM_FALSEP.

        (symbol_name, scm_make_hook_with_name): Removed.

        (scm_create_hook): Don't set the hook's name property.

        scm_print_real, scm_print_complex): Renamed SCM_FLOBUFLEN to
        FLOBUFLEN and define it unconditionally.

2001-05-07  Marius Vollmer  <mvo@zagadka.ping.de>

        * gh_data.c (gh_lookup): Call gh_module_lookup with
        `scm_current_module ()', not `#f'.
        (gh_module_lookup): Expect a module instead of an obarray as first
        argument and do lookup in that module.

        * ramap.c (raeql_1): Do not call scm_uniform_vector_length on
        arrays.  The length of array is already determined differently and

2001-04-01  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * gc.c (MARK):  Re-introduce a cheap sanity test for non debug
        mode, as suggested by Michael Livshin.

2001-03-31  Michael Livshin  <mlivshin@bigfoot.com>

        * backtrace.c (display_backtrace_body): since the `print_state'
        variable is not used (instead its data field is used directly as
        `pstate'), protect it from the hungry compiler optimizations.
        thanks to Bill Schottstaedt for the report.

2001-03-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * gc.[ch] (scm_tc16_allocated):  New type tag for allocated cells.
        It is only defined and used if guile is compiled with
        SCM_DEBUG_CELL_ACCESSES set to true.  It's purpose is, to never
        let cells with a free_cell type tag be visible outside of the
        garbage collector when in debug mode.

        * gc.c (scm_debug_cell_accesses_p):  Set to true as default.

        (scm_assert_cell_valid):  Use a local static variable to avoid
        recursion.

        (MARK):  Only check for rogue cell pointers in debug mode.  Use
        scm_cellp for this purpose and place all checks for rogue pointers
        into that function.  Further, since due to conservative scanning
        we may encounter free cells during marking, don't use the standard
        cell type accessor macro to determine the cell type.

        (scm_cellp):  Check if the cell pointer actually points into a
        card header.

        (scm_init_gc):  Initalize scm_tc16_allocated.

        * gc.h (GCH):  Renamed to SCM_GC_H.

        (SCM_VALIDATE_CELL):  Enclose the expression in brackets.  This
        might be unnecessary, but I feel better this way :-)

        (SCM_GC_CELL_TYPE):  New macro.

        (SCM_SETAND_CDR, SCM_SETOR_CDR):  Deprecated.  These are not used
        in guile, and it is unlikely that they will be applied to real
        pairs anyway.

        (SCM_SET_FREE_CELL_TYPE):  Removed.  It was not used.

        (SCM_GC_SET_ALLOCATED):  New macro.  Only non-empty if guile is
        compiled with SCM_DEBUG_CELL_ACCESSES set to true.

        (SCM_NEWCELL, SCM_NEWCELL2):  Use of SCM_GC_SET_ALLOCATED will
        make sure that in debug mode no free cell will ever be visible
        outside of the garbage collector.

2001-03-30  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * async.c (scm_asyncs_pending):  Don't use != to compare SCM

        * async.c (scm_system_async), variable.c (scm_make_variable,
        scm_make_undefined_variable):  Use scm_cons to create a pair.

        * debug.c (scm_reverse_lookup):  Perform proper type checking.
        Remove suspicious use of SCM_SLOPPY_CONSP.

        * eq.c (scm_equal_p), tags.h (SCM_ECONSP):  Use SCM_CONSP instead
        of SCM_SLOPPY_CONSP.  A sane compiler should be able to perform
        the corresponding optimization.

        * eval.c (iqq):  Use proper type check.

        (scm_m_expand_body):  Remove redundant type checks.

        (promise_print):  Don't access promise cells as pairs.

        * eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
        scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
        (scm_internal_hash_fold), print.c (scm_iprlist):  Use !SCM_CELLP
        for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
        !SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP

        * eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
        (scm_iprin1):  Use new macro predicate and accessors.

        * eval.h (scm_tc16_macro):  Removed declaration.  It is declared
        in macros.h.

        * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
        (PROCSH), tags.h (TAGSH), variable.h (VARIABLEH):  Renamed to
        SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
        SCM_VARIABLE_H.  Even the macros that are used to inhibit
        including a header file twice should be in the SCM_ namespace.

        * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
        properties.c (scm_primitive_property_ref,
        scm_primitive_property_del_x):  Prefer stronger predicates like
        SCM_NULLP or SCM_FALSEP over SCM_IMP.

        * gc.c (MARK):  Use proper macros to access procedure-with-setter
        cell elements and closure cell elements.

        (gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg):  Don't
        access free cells as pairs.

        (scm_unprotect_object):  scm_hashq_get_handle returns #f if
        no hashtab entry is found.

        * gc.c (scm_gc_sweep), ports.c (scm_close_port):  Use new macro
        SCM_CLR_PORT_OPEN_FLAG.

        * guardians.c (TCONC_IN), print.c (scm_free_print_state):  Don't
        use SCM_SET_C[AD]R for uninitialized cells.

        * hashtab.c (scm_hash_fn_get_handle):  Use SCM_VALIDATE_VECTOR.
        If the hashtable has no slots, return #f instead of '().  This
        unifies the return value with most assoc-functions.

        (scm_hash_fn_ref):  Use proper type check.

        (scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
        Removed references to non-existing functions from documentation.

        * keywords.c (scm_keyword_dash_symbol):  Use proper macros to
        access keyword cell elements.

        * macros.h (SCM_MACROP, SCM_MACRO_TYPE, SCM_MACRO_CODE):  New
        macros.

        * ports.h (SCM_CLR_PORT_OPEN_FLAG):  New macro.

        * print.c (scm_iprlist):  Added comment.  Improved loop
        conditions.

        * procs.h (SCM_ENV, SCM_SETENV):  Don't access closure cells as
        pairs.

        * smob.c (scm_markcdr):  Don't access smob cells as pairs.

        * tags.h (SCM_SLOPPY_CONSP, SCM_SLOPPY_NCONSP):  Deprecated.

        * throw.c (ACTIVATEJB, DEACTIVATEJB):  Don't access jump buffer
        cells as pairs.

        * variable.c (variable_print, variable_equalp, scm_variable_ref,
        scm_variable_set_x):  Use proper macros to access variable cell
        elements.

        (scm_variable_bound_p):  Don't use SCM_NEGATE_BOOL.

        * variable.h (SCM_VARVCELL):  Don't access variable cells as
        pairs.

        * vectors.c (scm_vector), weaks.c (scm_weak_vector):  Simplified,
        added FIXME comment, removed register specifier.

2001-03-29  Keisuke Nishida  <kxn30@po.cwru.edu>

        * goops.c, goops.h (scm_init_oop_goops_goopscore_module): Deprecated.
        * init.c (scm_init_guile_1): Don't init goopscore module.

2001-03-27  Marius Vollmer  <mvo@zagadka.ping.de>

        * eval.c (SCM_APPLY): Check that arg1 is bound for scm_tc7_cxr.

        (scm_string_capitalize): Rewrote and corrected docstrings.
        (scm_string_ci_to_symbol): Made docstring more explicit.

2001-03-27  Marius Vollmer  <mvo@zagadka.ping.de>

        * values.h (scm_values_vtable, SCM_VALUESP): Moved here so that
        eval.c can use it.
        (scm_call_with_values): Removed.
        * values.c (values_vtable, scm_values_vtable): Added "scm_" prefix
        so that it can be exported.
        (scm_call_with_values): Removed.

        * tags.h (SCM_IM_CALL_WITH_VALUES): New isym.
        * eval.c: Include "libguile/values.h"
        (scm_m_at_call_with_values, scm_sym_at_call_with_values):
        New.
        (unmemocopy, scm_ceval, scm_deval): Handle new isym.

        * guile-snarf.awk.in: Substitute "\\" with "\" in .doc output.

        * strop.c (scm_string_index): Fix docstring line break
        regression.

        * list.c (scm_cons_star): Fix docstring typo.

        * posix.h: declare scm_mkstemp.

        * net_db.c: declare h_errno if configure didn't define HAVE_H_ERRNO.
        normally it would be found in netdb.h.

        built with SCM_DEBUG_REST_ARGUMENT=1)

        (scm_array_in_bounds_p, scm_uniform_vector_ref, scm_array_set_x):

        (scm_getpriority, scm_setpriority, scm_getpass, scm_flock),
        (scm_sethostname, scm_gethostname): New procedures.

2001-03-08  Neil Jerram  <neil@ossau.uklinux.net>

        * ports.c (scm_port_column): Docstring fixes: (i) port-line arg is
        not optional (ii) "recommend" spelling correction.

2001-03-08  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        * ramap.c (racp): Removed optimization which caused array copying
        to fail if the two arrays shared storage.  Re-inserted the IVDEP
        macros removed in the change of 2000-03-09.  (Don't really have a
        complete grasp of what they are for, but they seem to be necessary
        on Crays.  This needs testing!)  Thanks to Miroslav Silovic.

        * hash.c (scm_string_hash): Don't downcase characters.

2001-03-07  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

2001-03-07  Keisuke Nishida  <kxn30@po.cwru.edu>

        * Makefile.am (*.x): Add dependency on snarf.h and guile-doc-snarf.in.
        (*.doc): Add dependency on guile-snarf.awk.in.

        * guile-snarf.awk.in: Neglect spaces at the end of
        SCM_SNARF_DOCSTRING_END.  Skip lines "# NN ..." in the
        middle of docstrings.  (To avoid the problem with gcc-2.96.)

        about the expected type with the wrong-type-arg error message.

        a C level bug that can't be fixed from scheme anyway.

2001-03-05  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        * eval.c (scm_m_letstar): Removed check for duplicate bindings.
        Duplicate bindings are OK in a let* since a let* is semantically
        equivalent to a nested set of let:s.

2001-03-05  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

        * print.c (scm_print_options): Fixed texinfo in docstring.

        * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
        the underlying functions getservent, getprotoent or getnetent
        return NULL instead of signalling an error.

2001-03-04  Gary Houston  <ghouston@arglist.com>

        * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
        taking an unexpectedly large filename for an AF_UNIX socket from

        size_t as socklen_t substitute.  don't restrict args/return values
        to INUM: allow full range of int or size_t.
        (scm_fill_sockaddr): check arguments before allocating memory, to
        avoid leakage.  use malloc, not scm_must_malloc.
        (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
        substitute.  free the sockaddr structure before throwing an error.
        (scm_init_add_buffer): procedure removed, together with its static
        buffer scm_addr_buffer, which wouldn't be thread safe.  instead,
        define a macro MAX_ADDR_SIZE and declare the buffer where needed.
        (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
        scm_sendto): use a local buffer instead of scm_addr_buffer.
        adjust for new SCM_SOCK_FD_TO_PORT.  use int for address size,
        not size_t.
        (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
        call to detect whether recvfrom could be bothered to set the address.
        (scm_init_socket): don't call scm_init_addr_buffer.

        (scm_m_lambda): Check for duplicate arguments.
        (scm_ceval, scm_deval): When executing a body: only cons a new
        toplevel environment frame when it is different from the
        existing one; use EVALCAR instead of SIDEVAL so that we can properly
        check for empty combinations; use SCM_EVALIM2 for the same reason
        in the non-toplevel loop.
        (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
        New labels with the meaning of their non-"nontoplevel" partners,

        top-level.

2001-02-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * __scm.h (SCM_ASSERT_TYPE):  Add missing macro parameter.
        (Obviously nobody compiles with SCM_RECKLESS defined...)

        * validate.h (SCM_ASSERT_RANGE):  Use the argument number.

2001-02-23  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

        * ports.c, ports.h (scm_c_read, scm_c_write): New functions.

        * ports.h (SCM_READ_BUFFER_EMPTY_P): New macro.

2001-02-24  Neil Jerram  <neil@ossau.uklinux.net>

        * numbers.c (scm_two_doubles, scm_sys_expt, scm_sys_atan2,
        scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
        since use of `z' suggests that the arguments may be complex.

        * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring
        typos.

2001-02-23  Neil Jerram  <neil@ossau.uklinux.net>

        scm_i_eval.
        (make_class_from_template): Do not bother to set the current
        module around the call to DEFVAR, scm_eval takes care of that.
        (scm_init_goops): Make scm_module_goops and
        scm_goops_lookup_closure permanent objects.

        * eval.c (scm_ceval, scm_deval): When evaluating expressions on
        top level, create a fresh top-level environment for each
        expression instead of mutating the exisint frame.  This is
        important when that frame is closed over.

        * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
        SCM_DIGSPERLONG instead of DIGSPERLONG.

2001-02-21  Marius Vollmer  <mvo@zagadka.ping.de>

        * eval.c (scm_ceval, scm_deval): Check for wrong number of args
        before applying arrow procedure in `cond' and before applying
        receiver procedure in call-with-current-continuation.
        (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
        macro.  The argument is expanded more than one time.

        * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
        SCM_BIGDIG instead of BIGDIG.  Thanks to Steven G. Johnson!

2001-02-20  Marius Vollmer  <mvo@zagadka.ping.de>

        * guile-doc-snarf.in, guile-func-name-check.in: Added copyright
        notice and license.

        Added texinfo markup.

        * arbiters.c (scm_make_arbiter, scm_try_arbiter)
        (scm_release_arbiter): Added texinfo markup to docstrings.
        Changed `Returns' to `Return'.
        (arbiter_print): Changed SCM_CDR to SCM_SMOB_DATA.

2001-02-16  Neil Jerram  <neil@ossau.uklinux.net>

        * guile-snarf.awk.in: Quote any `@'s that occur in Scheme names,
        by doubling them to `@@'.

2001-02-13  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

        * gc_os_dep.c: Do not include <linux/version.h>.  It makes no
        sense to compile for a specific kernel version.  Do not include
        <asm/signal.h> while defining __KERNEL__.  This hack should no
        longer be needed and caused problems.

2001-02-13  Marius Vollmer  <mvo@zagadka.ping.de>

        * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of
        SCM_CEVAL when evaluating subforms of `begin' forms.  SCM_CEVAL
        can not deal with immediates.

2001-02-12  Keisuke Nishida  <kxn30@po.cwru.edu>

        * list.c (scm_list_copy): Validate the first argument.

        function.

        * eval.h (scm_primitive_eval, scm_primitive_eval_x): New
        prototypes.
        (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
        names to better reflect their meaning.

        * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
        evaluated at top-level and synronize lookup closure before
        executing every subform.
        (scm_primitve_eval_x, scm_primitive_eval): New functions.
        (scm_eval_x, scm_eval): Reimplement in terms of
        scm_primitive_eval_x and scm_primitive_eval, respectively.

2001-02-09  Marius Vollmer  <mvo@zagadka.ping.de>

        * macros.c (scm_macro_name, scm_macro_transformer): Use

        * ports.c (scm_unread_char): Take an optional argument.

2001-02-08  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

        * modules.h (scm_selected_module, scm_current_module): Renamed
        scm_selected_module to scm_current_module to synchronize Scheme
        and C names.
        (scm_select_module, scm_set_current_module): Likewise.  Changed
        all uses.

        * ports.c (scm_port_for_each): Make a snapshot of the port table
        before iterating over it.  The table might change while the user
        code is running.  With the snapshot, the user can depend on the
        fact that each port that existed at the start of the iteration is
        encountered exactly once.  (ice-9 popen) depends on this.

2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * strings.h (SCM_STRING_MAX_LENGTH):  New macro.

        * strings.c (scm_makstr, scm_take_str, scm_make_string):  Added
        range checking for the size parameter.  Thanks to Martin
        Grabmueller for the hint.

        (scm_makstr):  Reordered string initialization to make interrupt
        deferring unnecessary.

        * vectors.c (scm_make_vector):  Fixed range checking.

2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * vectors.h (SCM_VECTOR_MAX_LENGTH):  New macro.

        * vectors.c (scm_make_vector, scm_c_make_vector):  Improved the
        checking of the size parameter for type correctness and valid
        range.  Thanks to Rob Browning for reporting the problem.  Instead
        of deferring interrupts, scm_remember_upto_here_1 is used.

2001-02-05  Keisuke Nishida  <kxn30@po.cwru.edu>

        * dump.c (scm_store_cell_object, scm_restore_cell_object): Removed.

        (keyword_undump): Renamed from keyword_alloc.
        (scm_init_keywords): Set keyword_dump and keyword_undump.

2001-02-03  Michael Livshin  <mlivshin@bigfoot.com>

        * gc.c (DOUBLECELL_ALIGNED_P): new macro, a better-named analog of
        the deprecated SCM_DOUBLE_CELLP.

        * tags.h (SCM_DOUBLE_CELLP): deprecated.

2001-02-02  Keisuke Nishida  <kxn30@po.cwru.edu>

2001-01-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * backtrace.c (display_header):  Make sure that line and column
        information is shown independent of whether the port the code was
        read from had an associated filename.  Thanks to Martin
        Grabmueller for providing this patch.

2001-01-25  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        ordering predicates.

        * strorder.c (string_less_p, string_ci_less_p):  New functions.

        (scm_string_less_p, scm_string_ci_less_p):  Extracted the core
        functionality into string_less_p, string_ci_less_p respectively.
        The remaining code is just a wrapper to do the parameter
        checking.

        (scm_string_leq_p, scm_string_gr_p, scm_string_geq_p):  Check the
        parameters and call string_less_p instead of scm_string_less_p.

        (scm_string_ci_leq_p, scm_string_ci_gr_p, scm_string_ci_geq_p):
        Check the parameters and call string_less_ci_p instead of

2001-01-24  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        This patch modifies scm_display_error to perform parameter

        (scm_closedir, scm_dir_print):  Rewritten to use SCM_DIR_OPEN_P
        instead of SCM_OPENP and SCM_CLOSEDP.

2001-01-22  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * eval.c (inner_eval, scm_eval):  Move all real functionality into
        inner_eval.  Avoid to copy the expression twice by inlining some
        code from scm_i_eval.

        * eval.c (scm_m_case):  The 'else' clause of a 'case' statement
        now has to be the last clause, as required by R5RS.  Thanks to
        Martin Grabmueller for the patch.

2001-01-18  Gary Houston  <ghouston@arglist.com>

        * ioext.c: further simplify scm_read_string_x_partial by defining

2001-01-17  Dirk Herrmann  <D.Herrmann@tu-bs.de>

        * __scm.h (SCM_FIXNUM_BIT):  Added.  The name is chosen in analogy
        to the names in limits.h.

        * numbers.c (abs_most_negative_fixnum):  Added.

        (scm_quotient, scm_remainder):  Fixed the fixnum-min / (abs
        fixnum-min) special case.

        (scm_big_and):  Fix for negative first parameter.

        (scm_bit_extract):  Fix for fixnum paramters.
        Thanks to Rob Browning for the bug report.

        Thanks to Bill Schottstaedt.

2001-01-11  Michael Livshin  <mlivshin@bigfoot.com>

        from Matthias Köppe:

        * objects.h (SCM_SET_ENTITY_SETTER): new macro.  SCM_ENTITY_SETTER
        casts its result, so doesn't yield an lvalue per ANSI C.

        * goops.c (s_scm_sys_set_object_setter_x): use
        SCM_SET_ENTITY_SETTER.
        (clear_method_cache): use SCM_SET_ENTITY_PROCEDURE.

        * gc.h (SCM_GC_SET_CARD_BVEC): new macro.  SCM_GC_CARD_BVEC casts
        its result, so doesn't yield an lvalue per ANSI C.
        (SCM_GC_SET_CARD_FLAGS): ditto for SCM_GC_GET_CARD_FLAGS.
        (SCM_GC_CLR_CARD_FLAGS): redefined in terms of
        SCM_GC_SET_CARD_FLAGS.
        (SCM_GC_SET_CARD_FLAG, SCM_GC_CLR_CARD_FLAGS): ditto.

        * gc.c (INIT_CARD): use the explicit setter macro to set the bvec.

2001-01-08  Gary Houston  <ghouston@arglist.com>

        * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): new macro.
        * ioext.c (scm_read_string_x_partial, scm_read_delimited_x),
        socket.c (scm_recvfrom): use the new macro, plus minor docstring
        changes.
        * ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
        for fdes.  if current input port is used, check that it's a file
        port.

2001-01-06  Gary Houston  <ghouston@arglist.com>

        * ioext.c (scm_read_string_x_partial): new procedure, implements
        read-string!/partial.
        * ports.c (scm_take_from_input_buffers): new procedure used by
        scm_read_string_x_partial.
        (scm_drain_input): use scm_take_from_input_buffers.

2001-01-06  Marius Vollmer  <mvo@zagadka.ping.de>

        * validate.h (SCM_VALIDATE_NUMBER): New.

2001-01-03  Michael Livshin  <mlivshin@bigfoot.com>

        SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
        SET_DESTROYED): new defines/macros.
        (GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
        (add_to_live_list): takes a `guardian_t *' now, not SCM.
        (guardian_print): print more info.
        (guardian_apply): check if the guardian is destroyed, and throw an
        error if so.  take one more optional argument `throw_p'.
        (scm_guard): depending on the value of `throw_p', return a boolean
        result.
        (scm_get_one_zombie): remove redundant property test.
        (guardian_t): represent the various (currently 3, I hope nothing
        more gets added) boolean fields as bit flags.
        (scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
        (scm_destroy_guardian_x): new procedure.

        `scm_guardian_destroyed_p'.  changed prototype for `scm_guard'.

2001-01-01  Gary Houston  <ghouston@arglist.com>

        * fports.c (fport_write): bugfix: handle short writes for
        unbuffered ports too.  optimize the buffered case by minimizing
        the number of write/flush calls.
        (write_all): new helper procedure.
