3 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
4 it shows up as terrible performance, as we GC constantly.
6 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
7 newline. A bit faster, and definitely hairier.
8 (scm_read_line): Count newlines here instead.
10 * strings.c (scm_take_str): New function.
11 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
12 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
13 scm_take_str, to avoid copying the string.
15 Add some simple-minded support for line buffered ports.
16 * ports.h (SCM_BUFLINE): New flag for ports.
17 * init.c (scm_init_standard_ports): Request line-buffering on
18 the standard output port.
19 * * ports.c (scm_mode_bits): Recognize 'l' as a request for line
21 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
22 and there's a newline to be written, flush the port.
24 Gary Houston's open-buffer port patches:
26 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
28 * ports.c: (scm_lseek): clear buffers even if just reading current
31 * fports.c (local_fclose): call local_fflush unconditionally.
32 (various): don't use the scm_must... memory procs.
34 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
36 * ports.h (scm_port): make read_pos a pointer to const.
37 strports.c: take care of rw_active and rw_randow.
38 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
39 strports.c (scm_mkstrport): check that pos is reasonable.
40 ioext.c (scm_ftell, scm_fseek): use lseek.
41 (SCM_CLEAR_BUFFERS): macro deleted.
42 ioext.c (redirect_port: use ptob fflush, read_flush.
43 ports.h (scm_ptobfuns): add ftruncate.
44 ports.c (scm_newptob): set ftruncate.
46 * ports.c (scm_ftruncate): new procedure.
47 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
48 strports.c (st_seek, st_grow_port): new procs.
49 fports.h (scm_port): change size types from int to off_t.
50 ports.c (scm_init_ports): initialise the seek symbols here
51 instead of in ioext.c.
52 strports.c (scm_call_with_output_string): start with an empty
53 string, so seek and ftruncate can be used.
55 gdbint.c: adjust string port usage.
57 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
59 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
60 equivalent to fflush for the read buffer.
61 * ports.c (scm_newptob): set read_flush.
62 ports.c (void_port_ptob): set read_flush.
63 fports.c (local_read_flush): new proc. add to ptob.
64 strport.c (st_read_flush): likewise.
65 vport.c (sf_read_flush): likewise.
66 fports.h (struct scm_fport): remove random member. there's nothing
67 left but fdes. leaving it as a struct to allow for future changes.
68 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
69 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
70 ptob proc if the read buffer is filled.
72 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
74 * ports.h (scm_port): add a rw_random member and replace
75 reading and writing members with rw_active member.
76 SCM_PORT_READ/SCM_PORT_WRITE: new values.
78 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
80 * ports.h (struct scm_port_table): add writing and reading members
81 to replace write_needs_seek: it isn't good enough for non-fports.
82 ports.c, ioext.c, fports.c: corresponding changes.
83 (struct scm_port_table): give it a typedef and rename to scm_port.
84 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
85 corresponding changes.

90 * * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
91 and generalised to all port types.
93 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
95 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
96 signals (it was only being done for handlers installed from Scheme).
97 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
98 waiting for input caused an EINTR error from read.
100 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
102 * ports.h (struct scm_port_table): make all the char members
103 unsigned, so they convert to int without becoming negative if large.
105 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
107 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
108 with threads enabled. rename this procedure to
109 fport_wait_for_input and take a port instead of a fdes.
110 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
112 * readline.c (scm_readline): Applied a patch from Greg Harvey to
113 get readline support working again: use fdopen to get FILE objects.
115 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
117 * gc.c (scm_init_storage): install an atexit proc to flush the
119 (cleanup): the new proc. it sets a global variable which can be
120 checked by the ptob flush procs to avoid trying to throw
121 exceptions during exit. not very pleasant but it seems more reliable.
122 * fports.c (local_fflush): check terminating variable and if set
123 don't throw exception.
124 * CHECKME: that the atexit proc is installed if unexec used.
126 * throw.c (scm_handle_by_message): don't flush all ports here.
127 it still causes bus errors.
129 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
132 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
134 * ports.c (scm_char_ready_p): check the port buffer and call the
135 ptob entry if needed.
137 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
138 ptob initialisers. use it in char-ready
140 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
142 * vports.c (sfflush): modified to write a char (since softports
143 currently use shortbuf.)
145 * fports.c (scm_standard_stream_to_port): moved to init.c and
148 * init.c (scm_init_standard_ports): make stdout and stderr
149 unbuffered if connected to a terminal. with stdio they
150 were line-buffered by default.
152 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
155 * ports.h (scm_ptobfuns): change fflush return to void.
156 change flush proc definitions.
158 * strports.c (scm_call_with_output_string): get size from
159 buffer instead of port stream.
160 (scm_strprint_obj): likewise.
161 (st_flush): new proc.
163 * ports.h (struct scm_port_table): added write_end member,
164 as an optimisation. set it where write_buf_size is set.
166 * ports.h (struct scm_port_table): change stream from void *
167 back to SCM. SCM presumably must be large enough to hold a
168 pointer (and probably vice versa but who knows.)
169 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
171 (scm_puts): rewritten
172 * fports.c (local_ffwrite, local_fputs): removed.

184 * ports.h (scm_ptobfuns): add seek function pointer.
185 * fports.c: set it to local_seek, new procedure.
188 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
189 use ptob for seek. take ptob instead of fport arg.
191 * ports.h (struct scm_port_table): new member write_needs_seek,
192 replaces reading member in fport struct.
194 * vports.c (sfgetc): store the getted char into the buffer.
195 rename to sf_fill_buffer and install it for fill-buffer in ptob.
196 the Scheme interface is still a procedure that gets a char.
197 (scm_make_soft_port): set up the port buffer (shortbuf).
199 * fports.c (local_fgetc, local_fgets): deleted.
200 * strports.c (stgetc): likewise.

206 put just the string into the stream, not cons (pos stream).
207 (stfill_buffer): new proc.
209 * ports.h: fport buffer moved into port table: to be
210 used for all port types.

526 * eval.c, eval.h (scm_top_level_lookup_closure): Removed.
528 1999-03-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
530 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
531 scm_misc_error when pos is a string. This allows for dispatching
532 arbitrary error messages with one argument via SCM_ASSERT:
533 SCM_ASSERT (<cond>, obj, "Undigestable object: %S", <subr>);
535 1999-03-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

543 Most of this batch of changes is about how to deal with extended
544 types when an object system is loaded into Guile. A nice object
545 system is capable of representing Guile's types as class objects.
547 For example, we want a regular expression to be of class <regex>.
548 But regular expressions are smobs which aren't under direct
549 control of the object system, so there has to be some mechanism
550 which informs the object system that a new class should be created
551 which can represent the smob type. I call this a "wrapper class".
553 * objects.c: #include "smob.h";
554 (scm_class_keyword): Removed. (Class is automatically created by
556 (scm_smob_class): Array of smob classes indexed by smobnum.
557 (scm_make_extended_class): "Plugin" function pointer for creation
558 of wrapper classes for smob and struct types.
559 (scm_class_of): Handle compiled closures. (Currently regarded as
561 Use scm_smob_class to handle smob types;
562 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
563 through scm_smob_class;
566 * smob.c (scm_newsmob): Also create a wrapper class if
567 scm_smob_class has been initialized.
569 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
570 type code and smobnum.
572 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
573 (scm_struct_table): Weak key table with auxilliary information for
574 struct types. Currently used for names and wrapper classes.
575 (scm_struct_ihashq): Hash function for structs.
576 (scm_struct_create_handle): Get/create entry in scm_struct_table.
577 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
578 for accessing names of vtables. The record implementation in
579 boot-9.scm currently uses the setter to record the name of record
580 types. When the object system is initialized, it can use this
581 information to create wrapper classes with suitable names.
582 (scm_init_struct): Allocate scm_struct_table.
583 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
584 (struct tags are a finite resource and we might want to restrict
585 the use of tags to vtables only. E.g., Goops only uses tags for
587 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
589 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
592 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
593 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
594 Used for access of struct table entries.
596 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
597 (scm_hash_fold): New procedure. Used to process all entries in a
598 hash table (in no particular order).
600 Argh! For the umpteenth time I got compilation errors because of
601 the "intuitive" name `kw'. This has to have an end:
603 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
604 "kw" --> "keywords" everywhere.
605 (I doubt that this will cause big compatibility problems since the
606 application interface is unaffected.)
608 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
610 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
612 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
613 column inums to native form.
615 Improvement of backtraces: Introduces a new stack narrowing
616 specifier, #t, for the inner cut. (See further in the comments in

643 procedure throughout.
645 * print.c (scm_iprin1): Removed extraneous space when printing
646 procedure-with-setters.
648 Entity and operator setter slots were introduced as a complement
649 to the <procedure-with-setter> type in order to support entities
650 and operators with setters in a reasonable and efficient way.
651 * procs.c (scm_procedure, scm_setter): Handle entity and operator

671 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
672 scm_struct_i_flags instead of scm_vtable_index_layout!
674 * list.c (scm_list_star): New procedure.
676 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

757 SYMB now point to const.
759 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
761 * print.c (scm_iprin1): Use scm_procedure_name instead of
762 scm_procedure_property for compiled closures.
764 * tags.h (scm_tc7_pws): New procedure type. Four representations
765 for procedure-with-setters were considered before selecting this
768 1. A closure where the CODE and ENV slots are used to represent
769 the getter and a new SETTER slot is used for the setter. The
770 original getter is stored as a `getter' procedure property. For
771 closure getters, the CODE and ENV slots contains a copy of the
772 getter's CODE and ENV slots. For subr getters, the CODE contains
775 2. A compiled closure with a call to the getter in the cclo
776 procedure. The getter and setter are stored in slots 1 and 2.
778 3. An entity (i.e. a struct with an associated procedure) with a
779 call to the getter in the entity procedure and the setter stored
780 in slot 0. The original getter is stored in slot 1.
782 4. A new primitive procedure type supported in the evaluator. The
783 getter and setter are stored in a GETTER and SETTER slot. A call
784 to this procedure type results in a retrieval of the getter and a
785 jump back to the correct eval dispatcher.
787 Representation 4 was selected because of efficiency and
790 Rep 1 has the advantage that there is zero penalty for closure
791 getters, but primitive getters will get considerable overhead
792 because the procedure-with-getter will be a closure which calls
795 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
796 <procedure-with-setter>, but together with rep 2 it suffers from a
797 three level dispatch for non-GOOPS getters:
799 cclo/struct --> dispatch proc --> getter
801 This is because the dispatch procedure must take an extra initial
802 argument (cclo for rep 2, struct for rep 3).
804 Rep 4 has the single disadvantage that it uses up one tc7 type
805 code, but the plan for uniform vectors will very likely free tc7
806 codes, so this is probably no big problem. Also note that the
807 GETTER and SETTER slots can live directly on the heap, using the
810 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

1045 Added #include "procprop.h"
1047 * feature.c, feature.h (scm_reset_hook_x): New procedure.
1048 (scm_make_hook): Optional argument defines number of arguments to
1050 (scm_make_named_hook): Take number of args as second arg.
1051 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
1052 boot-9.scm for a while); First arg is the hook. The rest are
1053 arguments passed on to the hook procedures.
1055 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
1057 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1058 scm_logbit_p): Do the computation in ulongs. This is not as nice
1059 as doing it in bignums, but at least it's good enough for
1060 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1062 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1063 subexpressions. (Thanks to Charbel Jacquin.)
1065 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1067 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1068 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1069 (scm_make_named_hook): New function.
1071 * feature.c: Added #include "eval.h".
1073 * modules.c (scm_make_module): Beautify the module.
1075 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1077 * modules.c, modules.h: New files: C interface to modules. (This
1078 is necessary in order to interface the object system to Guile
1079 properly. The guts of these modules will be replaced by the new
1080 module system in the future.)
1082 * init.c: Added #include "modules.h"
1083 (scm_boot_guile_1): Call scm_init_modules.
1084 (invoke_main_func): Call scm_post_boot_init_modules.
1086 * Makefile.am: Added modules.c, modules.x, modules.h.
1088 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1090 * procs.c: #include "objects.h"
1091 (scm_procedure_p): Return #t also on structs which are operators.
1093 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1094 <operator-metaclass> and <entity-class> to <standard-class>,
1095 <operator-class> and <entity> in order to conform with STKlos
1098 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1099 which isn't an operator.
1100 (SCM_APPLY): Ditto, but jump to badproc.
1102 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1104 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1105 Previously, structs implanted in code were interpreted as forms
1106 the operator of which was a gloc. We solve this by checking for
1107 the zero in the emulated vcell in the struct vtable. Since
1108 implanted structs always will look like forms with a gloc
1109 operator, execution will only be slowed down by maximally one
1110 extra test-and-branch per application.
1112 * evalext.c (scm_definedp): Removed check for isyms; Added a
1113 second optional argument: It is now possible to supply an
1114 evaluation environment in which to look for the symbol.
1116 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1118 * readline.c (scm_init_readline): Set
1119 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1121 * coop.c (coop_condition_variable_wait): Removed
1122 (coop_condition_variable_wait_mutex): Folded logic of
1123 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1124 prevent condvar signal lossage. Previously, another thread could
1125 start to run after unlocking the mutex but before putting the
1126 current thread on the wait queue. If that thread then would
1127 signal the first, the signal would be lost. (Thanks to Christian
1130 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1132 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1135 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1137 * objects.c (scm_i_make_class_object): Renamed from
1138 make_class_object; exported; error checking moved to
1139 scm_make_class_object and scm_make_subclass_object.
1140 (scm_make_class_object, scm_make_subclass_object): Use
1141 scm_i_make_class_object.
1142 (scm_make_subclass_object): Let the subclass have same metaclass
1145 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1147 * debug.c (scm_debug_options): Bugfix: Set the value of
1148 scm_stack_checking_enabled_p after setting debug options;
1149 #include "stackchk.h". (Thanks to Richard Polton.)
1151 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1153 * unif.c (scm_array_contents): removed unnecessary test for 0
1156 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1158 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1159 Replaced by macro `collect' in boot-9.scm.
1161 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1163 * eval.c (scm_copy_tree): Copy source properties if existent.
1165 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1166 don't, we may end up passing memoized source to a transformer.)
1168 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1170 * stack.c (get_applybody): Help function which lookups the first
1171 body form of the apply closure.
1172 (read_frames): Prevent the source of the first form of the apply
1173 closure from being recorded. This would only be confusing.
1175 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1176 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1178 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1180 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1182 (read_frames): Use SCM_MACROEXPP.
1184 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1186 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
1187 don't contain interesting information since all arguments are
1188 present in the frame which applies the compiled closure anyway.);
1189 Skip the transformer application frames.
1191 * print.c (scm_iprin1): Print gsubrs as primitives.
1193 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1195 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
1197 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
1198 that we can identify these in a backtrace. (This change doesn't
1199 introduce any significant speed penalty.)
1201 * eval.c: Added note about `serial-map' using scm_map.
1203 * read.c, read.h (scm_read_options, scm_read_opts): Removed
1204 readline options. They should reside in their own options array.
1206 * readline.c, readline.h (scm_readline_options,
1207 scm_readline_opts): Moved readline options here.
1209 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1211 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
1212 SCM_ROCHARS instead of SCM_CHARS.
1214 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
1215 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
1217 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1219 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
1220 This is quite important since the latter clears the
1221 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
1222 every single character read...
1224 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1226 * print.c (scm_iprin1): Removed suspect looking (and indeed
1227 malevolent) semicolon after test for user supplied closure print
1228 procedure. (Thanks to Telford Tendys.)
1230 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
1231 (scm_memq, scm_memv, scm_member): Do argument checking *before*
1232 starting to search the list. Removed call to sloppy_mem_check.
1234 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
1235 procedures: Same as scm_delq_x et al, but delete maximally one
1238 * options.c (scm_options, scm_init_options): GC-protect option
1239 values of type SCM. (Thanks to Telford Tendys.)
1241 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1243 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
1244 make sure that there always is a "real" scm_lookupcar.
1246 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1248 * read.c, read.h (scm_read_opts): New read options
1249 "history-length" and "history-file".
1250 (scm_read_options): Stifle history to history length.
1252 * readline.c (scm_read_history, scm_write_history): New procedures.
1254 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1256 * eval.h (scm_macro_eval_x): Removed declaration.
1258 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
1259 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
1260 Renamed and made global.
1262 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
1263 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
1265 * evalext.c, evalext.h: New files. Contain non-R5RS things
1266 having to do with evaluation.
1268 * evalext.c (scm_serial_map): New procedure: Version of `map'
1269 which guarantees that the procedure is applied to the lists in
1271 (scm_m_sequence_to_list): New syntax: Version of `begin' which
1272 returns a list of the results of the body forms instead of the
1273 result of the last body form.
1274 (scm_definedp, scm_m_undefine): Moved from eval.c
1276 * evalext.h (scm_m_sequence_to_list): Added declaration.
1278 * macros.c, macros.h: New files.
1279 (scm_procedure_to_syntax, scm_procedure_to_macro,
1280 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
1281 scm_macro_name, scm_macro_transformer): Moved from eval.c
1282 (scm_make_synt): Moved from eval.c
1284 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
1286 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
1289 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
1291 * debug.c, print.c: Added #include "macros.h".
1293 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1295 This change adds the ability to use `unread-char' multiple times
1296 without interspersed reads and adds the new procedure
1297 `unread-string'. The change is optimized for the common case of
1298 unreading a single character. This is also the reason behind the
1299 choice to store characters in the port itself: in most cases no
1300 extra malloc is required.
1302 The amount of code in some macros in ports.h has been increased to
1303 the extent that they would fit better as C functions, but, since
1304 this code belongs to the port representation, such functions
1305 should be placed in ports.c which would cause calls back and forth
1306 between ports.c and genio.c. That is not good for performance.
1307 Also, keeping them as macros allows the compiler to do some
1308 optimizations which are needed to make the current interface
1309 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
1311 One benchmark (Guile startup time) indicates an increase of
1312 loading speed of 1%. Another (reading (using `read') boot-9.scm
1313 10 times) shows no change in performance.
1315 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
1316 made to find a beautiful solution.)
1318 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
1319 (SCM_TRY_CLRDY): New macro: Only clear the first unread
1320 character. (SCM_CLRDY clears all.)
1321 (SCM_N_READY_CHARS): New macro: Returns number of unread
1322 characters in a port. Returns wrong answer if SCM_CRDYP is false.
1323 (struct scm_port_table): New fields: `entry' contains port table
1324 index, `cp' points to last unread char, `cbuf' is the buffer for
1325 unread chars, `cbufend' points after end of the character buffer.
1327 * ports.h, ports.c (scm_unread_string): New procedure.
1328 (scm_grow_port_cbuf): New function.
1330 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
1332 (scm_generic_fgets), fports.c (local_fgets): Use a loop
1333 to read unread characters. Use SCM_TRY_CLRDY instead of
1336 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
1338 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
1340 * genio.c, genio.h (scm_ungets): New function.
1342 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
1345 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1347 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
1348 declarations. (Thanks to Russ McManus.)
1350 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1352 * numbers.c (num2long): As a software archeologist, I'm proud of
1353 this finding! :) Preliminary dating suggests an almost 4 year old
1354 remnant from the SCM ancestor. The sample has been removed from
1355 the finding site and is now safely stored in the repository.
1357 * numbers.h: Removed prototype for num2long.
1359 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
1361 * gh_data.c (gh_scm2doubles): Make it possible to pass result
1362 array as second arg.
1363 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
1364 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
1365 * gh.h: Updated and added prototypes.
1367 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
1369 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
1371 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
1373 * guile-snarf.in: Never generate an empty file. (Thanks to
1376 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
1377 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
1378 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
1379 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
1380 gh_new_procedure5_0): Specify argument types, to appease C++
1381 compilers. (Thanks to Brad Bowman.)
1383 Bug reports from Russ McManus:
1384 * guile-snarf.in: If the CPP environment variable is set, use that
1385 as the C preprocessor, instead of the preprocessor autoconf
1387 * snarf.h (SCM_PROC): Cast the function pointer passed to
1388 scm_make_gsubr, to satisfy C++.
1390 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
1391 Use the handler passed, instead of ignoring it and using
1392 gh_standard_handler. (Thanks to Etienne Bernard.)
1394 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
1396 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
1399 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
1401 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

1416 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
1419 * script.c (scm_compile_shell_switches): Define
1420 use-emacs-interface in the root module, so the repl code can see
1421 it. See today's change to top-repl in ice-9/boot-9.scm.
1423 * filesys.c (set_element, get_element): Make sure that `element'
1424 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
1425 Boekemeier and Jorgen "forcer" Schaefer.)
1427 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
1429 * chars.c (scm_charnames): In ASCII character name table, make
1430 newlines print as #\newline by default, not #\nl.
1432 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
1433 alphabetical order. Oh thrills. But it helps me know how far
1434 along in the compilation I am.
1435 * Makefile.in: Regenerated.
1437 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1439 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
1440 #bytes(...) to #y(...), and syntax for short vectors from
1441 #short(...) to #h(...). This may seem nutty, but, like the other
1442 uniform vectors, byte vectors and short vectors want to have the
1443 same print and read syntax (and, more basic, want to have read
1444 syntax!). Changing the read syntax to use multiple characters
1445 after the hash sign breaks with the conventions used in R5RS and
1446 the conventions used for the other uniform vectors. It also
1447 introduces complexity in the current reader, both on the C and
1448 Scheme levels. (The Right solution is probably to change the
1449 syntax and prototypes for uniform vectors entirely.)
1451 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
1453 Don't use local_fgets on sockets; ftell doesn't work on sockets.
1454 (Thanks to Jorgen "forcer" Schaefer.)
1455 * ports.h (SCM_NOFTELL): New flag.
1456 * fports.c (local_fgets): If it's set, use the generic fgets.
1457 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
1459 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1461 * script.c (scm_compile_shell_switches): Add handling of -q switch
1462 (inhibit loading of user init file).
1463 (scm_shell_usage): Add usage text for -q switch.
1464 (scm_compile_shell_switches): Always load user init file first if
1465 it is loaded at all.
1467 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
1469 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
1470 and is now broken under NetBSD. I can't fathom what it's trying
1471 to do, so I've replaced it with something that I do understand,
1472 which seems to work, and which isn't broken on NetBSD. "Progress?
1473 You Decide." (Thanks to Perry Metzger.)
1475 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
1476 signed/unsigned comparison.
1478 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
1480 Warning fixes from Greg Harvey:
1481 * unif.c (scm_array_set_x): initializer for pos
1482 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
1483 * struct.c (scm_struct_ref, scm_struct_set_x): Added
1484 initializers for field_type, since EGCS so desparately wants to
1486 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
1487 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
1488 when GUILE_DEBUG is defined.
1489 * dynwind.h (scm_wind_chain): Same.
1490 * ports.h (scm_pt_size, scm_pt_member): Same.
1491 * print.h (scm_current_pstate): Same.
1492 * procs.h (scm_make_cclo): Same.
1494 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
1496 Handle short and long long uniform arrays properly. (Thanks to
1498 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
1499 raeql_1): Add cases for scm_tc7_svect (short vectors) and
1500 scm_tc7_llvect (long long vectors).
1502 Change the way libguile and boot-9.scm are timestamped, to try to
1503 get rid of these spurious mismatch warnings. Now both
1504 libguile/versiondat.h and ice-9/version.scm are generated directly
1505 by the configuration process, rather than having version.scm
1506 generated directly, and libguile/versiondat.h generated by the
1507 Makefile, which is generated by configure. It seems that
1508 sometimes the Makefile would change, but versiondat.h depends on
1509 Makefile.in, not Makefile, so it wouldn't get rebuilt.
1510 * Makefile.am (versiondat.h): Target removed; this is generated
1511 directly by the configure script now.
1512 (BUILT_SOURCES): Remove versiondat.h.
1513 * versiondat.h.in: New file, transformed by the configure script
1515 * Makefile.in: Regenerated.
1517 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
1518 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
1519 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
1520 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
1521 if we want to use them in a header file some day, we can. (Thanks
1522 to Michael Livshin.)
1524 * stime.c (scm_get_internal_real_time): Do the arithmetic using
1525 SCM numbers, so we won't have rollover problems; the range of a
1526 signed long in milliseconds is about 25 days. (Thanks to Karl
1529 Don't redefine sleep and usleep; fix this problem now.
1530 * coop.c (sleep, usleep): Remove declarations; we don't use or
1531 redefine these any more.
1532 (scm_thread_usleep, scm_thread_sleep): New functions which do the
1533 job of usleep and sleep in a thread-friendly way. We can use
1534 these in the rest of Guile. Define versions for systems both with
1535 and without iselect.
1536 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
1537 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
1538 we're just using it, not redefining it, we can use a K&R style
1540 (sleep): Declare this, too, if the system hasn't.
1541 (scm_sleep, scm_usleep): Use scm_thread_sleep and
1542 scm_uthread_sleep if they're available; otherwise, just call the
1544 * scmconfig.h.in: Regenerated.
1546 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
1548 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
1550 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
1552 * threads.c: Doc fix.
1554 The argument type of usleep varies from system to system,
1555 as does the return type. We really shouldn't be redefining usleep
1556 at all, but I don't have time to clean that up before the 1.3.
1557 release. It's on the schedule for afterwards. (Thanks to Julian
1559 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
1561 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
1562 * scmconfig.h: Regenerated.
1564 * simpos.c (scm_software_type): Procedure deleted. This isn't the
1565 right way to handle system variation. Autoconf's approach is the
1567 * simpos.h (scm_software_type): Declaration deleted.
1569 * script.c (scm_find_executable): Don't test if unix is #defined
1570 here; first, NetBSD doesn't #define it, and second, it's the wrong
1571 way to go about these things. (Thanks to Perry Metzger.)
1572 (dld_find_executable): Delete this MSDOS support code. This isn't
1573 the way we want to support this; it needs to be rethunk at a
1576 * genio.c (scm_do_read_line): Don't just politely check that the
1577 line was either non-empty or EOF. Abort if it's empty and not
1580 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
1582 * scmconfig.h.in: Regenerated.
1584 * libguile.h: Don't omit the dynamic linking functions. (Thanks
1587 * genio.c (scm_do_read_line): Count lines correctly when the file
1588 doesn't end in a newline.
1590 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
1592 * genio.c (scm_do_read_line): Maintain the line count correctly.
1593 (Thanks to Harvey J. Stein and Greg Harvey.)
1595 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
1598 * numbers.c (big2str): Protect t from garbage collection until
1599 we're done. (Thanks to Gary Houston.)
1601 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
1603 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
1605 * Makefile.in: Regenerated.
1607 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
1608 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
1611 Do magic to mix reads and writes on stdio FILE-based ports.
1612 (Thanks to Christian Lynbech.)
1613 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
1615 (pre_read, pre_write): New functions.
1616 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
1617 local_fputs): Call them.
1618 (local_fflush): Mark the port as ready for reading and writing.
1619 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
1620 flags on new port objects. This might not be accurate --- who
1621 knows what state the FILE * is in when we get it --- but it won't
1622 do extraneous calls to fflush or fseek, so it's no worse than the
1623 behavior before this change.
1624 * ports.h: Add comment.
1626 Centralize the creation of port objects based on stdio FILE * in
1627 fports.c; don't just throw them together anywhere.
1628 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
1629 what the rest of Guile wants. Don't set the revealed count;
1630 that's only appropriate for stdin, stdout, stderr.
1631 (scm_standard_stream_to_port): This function does set the revealed
1633 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
1634 not scm_stdio_to_port.
1635 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
1636 * fports.c (scm_open_file): Same.
1637 * posix.c (scm_pipe): Same.
1638 * socket.c (scm_sock_fd_to_port): Same.
1639 * ioext.c (scm_fdopen): Same.
1640 (scm_freopen): Moved from here to...
1641 * fports.c (scm_freopen): ... here. This is really something that
1642 munges the internals of an fport, so it should go here.
1643 * fports.h (scm_stdio_to_port): Adjust prototype.
1644 (scm_standard_stream_to_port, scm_freopen): New protoypes.
1645 * ioext.h (scm_freopen): Prototype removed.
1647 * filesys.c (set_element, get_element): This can work on both pipe
1648 and file ports, so use SCM_FPORTP to typecheck, instead of testing
1651 * scmconfig.h.in: Regenerated.
1653 Change the definition of the functions in scm_ptobfuns so that
1654 they get passed the port object, not the port's stream.
1655 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
1656 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
1657 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
1658 Pass the port itself to the scm_ptobs function.
1659 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
1660 scm_generic_fgets): Same.
1661 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
1662 getc_void_port, fgets_void_port, close_void_port): Just change the
1663 argument names; these functions don't really do anything.
1664 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
1665 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
1666 port as an argument, and use SCM_STREAM to get the stdio FILE *.
1667 Also, use prototyped definitions, and get rid of the extra
1669 (scm_fptob, scm_pipob): We don't need casts here any more.
1670 * strports.c (prinstpt): Use prototype declarations.
1671 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
1672 and use SCM_STREAM to get the string info. Also, use prototyped
1673 definitions, and get rid of the extra declarations.
1674 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
1677 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
1678 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
1680 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
1681 scm_fgets, for consistency.
1682 (scm_fptop, scm_pipob): References updated.
1684 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
1686 Include the source location in error messages for scripts.
1687 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
1688 stack is still there when we catch the error.
1689 * throw.c (handler_message): If we are handling an error with a
1690 message, then put together the proper arguments and call
1691 scm_display_error, instead of scm_display_error_message. That
1692 displays source location, if it can find it.
1694 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
1696 * gc.c (scm_unprotect_object): Change this so that calls to
1697 scm_protect_object and scm_unprotect_object nest properly.
1698 (scm_protect_object): Doc fixes.
1700 * strings.c (scm_string_set_x): Require the argument to be a
1701 writable string, not a substring or a symbol.
1702 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
1703 (Thanks to John Redford and Charbel Jacquin.)
1705 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
1707 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
1709 * eval.c (safe_setjmp): Remove this misunderstanding.
1710 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
1713 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
1715 * libguile.h: Mark these as C declarations, for compilation by C++
1718 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
1719 __cplusplus clause. I seriously doubt this ever worked the way
1720 the author seems to have intended.
1722 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
1724 Utterly needless cleanups to hopelessly messy code.
1725 * ports.c: Doc fixes.
1726 (scm_fflush): Moved to ...
1727 * genio.c (scm_fflush): ... here, amongst all the other port
1728 method invocation functions.
1729 * genio.h, ports.h: The prototype moves too.
1731 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
1733 * backtrace.c (display_error_body): The current frame does not
1734 always have a parent frame; consider a function called directly
1735 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
1738 * alloca.c (alloca): Undo yesterday's changes, and simply call
1739 malloc directly for storage, and abort if we don't get what we
1740 want. The situation is much simpler --- just call malloc. Emacs
1741 has bizarre/evil requirements (signal handlers might malloc unless
1742 you set this global flag, so you have to set the flag around all
1743 calls to malloc) which we are certainly not going to conform to,
1744 so we can do the simple and obvious thing.
1746 * coop.c (coop_condition_variable_wait): Make this function
1747 static. It's only useful internally --- you should never just
1748 wait on a condition variable.
1749 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
1751 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
1753 * unif.c (scm_array_set_x): Accept any kind of number as an
1754 element for a uniform vector of doubles. This is more consistent
1755 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
1757 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
1758 works; I can't conveniently test it myself. (Thanks to Dvid
1759 Tillman for the bug report.)
1761 * init.c: Doc fixes.
1763 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
1764 from here, not from scm_compile_shell_switches (which is a pretty
1765 dumb place to do it).
1766 (scm_load_startup_files): New function.
1767 (scm_ice_9_already_loaded): Variable moved to here from script.c.
1768 * script.c (scm_compile_shell_switches): Don't load the startup
1770 (scm_ice_9_already_loaded): Variable moved.
1771 * init.c (scm_load_startup_files): Prototype for new function.
1772 * gh_init.c (gh_enter): Doc fix.
1774 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
1776 Some anti-warning changes from Greg Harvey.
1777 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
1778 warnings when it doesn't understand our NORETURN declarations in
1780 * posix.c (scm_mknod): Similar.
1782 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
1784 * posix.c (scm_getpwuid): If we can't find an entry, return our
1785 own message, instead of using scm_syserror --- the getpwMUMBLE
1786 functions don't set `errno' to anything interesting.
1788 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
1790 Get rid of warnings from the cooperative threading system.
1791 * threads.h (scm_single_thread_p, scm_yield,
1792 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
1793 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
1794 scm_wait_condition_variable, scm_signal_condition_variable): Add
1795 prototypes for these Scheme-visible functions.
1796 * coop-defs.h (coop_next_runnable_thread,
1797 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
1798 Prototypes for these here, even though they're from iselect.c.
1799 (coop_condition_variable_wait, coop_join): Add prototypes.
1800 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
1801 scm_threads_free_condvar): Make these smob functions static.
1802 * coop-threads.h (coop_init): Give this a real prototype.
1803 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
1804 (coop_next_runnable_thread): No need to provide prototype; it's in
1807 * scmconfig.h.in: .detarenegeR
1809 * iselect.c, threads.c: Doc fixes.
1811 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
1813 * Makefile.in: Regenerated with a patched automake, to get
1814 dependency generation right when using EGCS.
1816 * inet_aton.c (inet_aton): Add prototype, to remove compiler
1817 warning. (Thanks to Robert Pluim.)
1819 * inet_aton.c (inet_aton): Reassure the compiler that the
1820 arguments to the <ctype.h> macros are all unsigned characters, not
1823 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
1825 Getting rid of more warnings...
1826 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
1827 today's change to ../configure.in.
1828 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
1829 * scmconfig.h.in: Regenertaded.de.,.__
1830 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
1831 (scm_localtime, scm_mktime): Use a const char * to manipulate the
1834 * readline.c: Doc fix.
1835 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
1836 * readline.h (scm_filename_completion_function): Add prototype.
1837 (scm_init_readline): Make this into a prototype.
1839 * readline.c (scm_filename_completion_function): Use SCM_PROC to
1840 declare this, instead of calling scm_make_subr manually.
1842 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
1844 * readline.h (scm_init_readline): Add prototype for this.
1845 (scm_init_readline): Make this a real prototype.
1847 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
1849 Warning fixes from Maciej Stachowiak:
1850 * backtrace.h (scm_display_application, scm_backtrace): Add
1852 * debug.c (scm_m_start_stack): Make this function static.
1853 * fluids.h (scm_fluid_p): Add prototype.
1854 * procprop.c (scm_i_procedure_arity): Make this function static.
1855 * regex-posix.c (scm_regexp_error_msg): Make this function static.
1856 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
1857 * root.h (scm_dynamic_root): Add external prototype.
1858 * scmsigs.h (scm_usleep): Add external prototype.
1859 * script.h (scm_init_script): Use prototype, not K&R decl.
1860 * stacks.h (scm_stack_id): Add external prototype.
1861 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
1863 1998-09-30 Mark Galassi <rosalia@cygnus.com>
1865 * gh.h: took out the definitions of vset and vref, since they are
1866 replaced by the proper vector routines that correspond to the R4RS
1869 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
1871 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
1872 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
1873 third argument, a C expression that should result in a SCM value,
1874 which is used to initialize the variable. Reimplemented
1875 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
1878 * version.h (scm_libguile_config_stamp): Add prototype.
1879 (From Maciej Stachowiak.)
1881 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
1883 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
1884 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
1886 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
1888 * print.c (scm_iprin1): Rather than having one i, and using it in
1889 several places, declare a fresh i local to each block where it is
1890 used, and give it a signedness appropriate to its use in each case.
1891 (scm_iprlist): Same.
1893 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
1894 comparison warnings.
1896 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
1897 signed/unsigned clashes.
1899 * posix.h (scm_tmpnam): Added prototype.
1901 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
1902 scm_make_subclass_object): Add external prototypes.
1904 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
1905 comparison is okay here.
1907 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
1909 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
1910 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
1912 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
1915 * load.c (swap_port): Make this function static.
1917 * load.c (scm_search_path): Make max_path_len and max_ext_len
1918 unsigned, since they're compared against string sizes.
1920 * load.c (init_build_info): Make i unsigned.
1922 * ioext.h (scm_read_line): Add prototype.
1924 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
1925 scm_hash_fn_remove_x): Make hash bucket index local variable k
1926 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
1927 accurately as possible.
1929 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
1930 comparisons, and range checking to make sure those casts are
1933 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
1934 signed/unsigned comparisons.
1936 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
1937 avoid signed/unsigned comparisons.
1938 * smob.h (scm_numsmob): Change extern declaration to match.
1940 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
1941 avoid signed/unsigned comparisons.
1942 * ports.h (scm_numptob): Change extern declaration to match.
1943 (scm_current_load_port, scm_set_port_line_x,
1944 scm_set_port_column_x): New prototypes.
1946 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
1947 test code, and it causes warnings.
1949 * gh.h (gh_int2scmb, gh_uniform_vector_length,
1950 gh_uniform_vector_ref): Added prototypes.
1952 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
1953 debugging support unconditionally. That's backtrace.c, stack.c,
1954 debug.c, and srcprop.c.
1955 (EXTRA_libguile_la_SOURCES): Omit those from here.
1956 * Makefile.in: Regenerated.
1958 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1960 * options.c (scm_options): Bugfix: Allow empty list of options!
1962 * debug.c, debug.h (scm_single_step): Removed.
1963 (scm_with_traps): New procedure. This procedure could easily be
1964 written in Scheme but needs to be highly optimized.
1966 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
1968 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
1969 Check SCM_TRAPS_P before trapping.
1971 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
1973 Changes to avoid signed/unsigned comparison warnings.
1974 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
1975 (scm_gc_sweep): Make n and j local to the blocks they're used in,
1976 so they can have appropriate types for each application. Make i
1977 signed. Use initializers in some spots. I'll probably pay for
1979 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
1980 (scm_must_realloc): Make nm unsigned.
1981 (init_heap_seg): Make new_seg_index and n_new_objects signed.
1982 (scm_init_storage): Use prototype-style definition, and make the
1984 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
1985 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
1987 * filesys.c (scm_readlink): Make local vars rv and size ints, to
1988 avoid signed/unsigned comparison warnings, and because the return
1989 value of readlink may be -1. Don't bother casting the third
1990 argument to readlink.
1992 * filesys.c (scm_dirname, scm_basename): Move these to their own
1993 page, at the end of the file.
1994 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
1996 * eval.h (scm_eval_options_interface): Add external prototype for this.
1997 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
1999 * eval.c (scm_lookupcar1): Make this static.
2001 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2002 Make these prototype declarations, not K&R-style.
2004 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2005 unsigned comparison warning.
2007 * appinit.c: File removed. It had a single function in it, empty,
2008 whose reason for existence is explained in no documentation or
2009 comment. I think it's there as a default for some Tcl-style
2010 initialization, but Tcl abandoned that approach a while ago.
2011 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2012 (BUILT_SOURCES): Remove appinit.x.
2013 * Makefile.in: Regenerated.
2015 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2017 * Makefile.in: Regenerated using the last public version of
2018 automake, not the hacked Cygnus version.
2020 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2022 Remove Totoro kludge.
2023 * Makefile.in, scmconfig.h.in: Regenerated.
2024 * init.c, readline.c: Don't check if TOTORO is #defined.
2026 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2028 * Makefile.am: Adjust for new thread configuration system.
2029 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2030 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2032 (THREAD_LIBS): Definition deleted; automake will generate such
2033 things automatically.
2034 * Makefile.in: Regenerated.
2036 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2038 Simplify smob and port marking; set the mark bit in the generic
2039 marking code, and make marker routines only responsible for
2040 turning up outgoing pointers.
2041 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2042 before calling the marking function. Don't call the marking
2043 function if it's zero.
2044 * markers.c (scm_mark0): Just return #f. This function isn't
2045 necessary at all now, but it's harmless to call it. We'll leave
2046 it in so other folks' code doesn't croak at link time.
2047 (scm_markcdr): Don't call SCM_SETGC8MARK.
2048 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2049 * dynl.c (mark_dynl_obj): Same.
2050 * root.c (mark_root): Same.
2051 * srcprop.c (marksrcprops): Same.
2052 * unif.c (markra): Same.
2053 * variable.c (scm_markvar): Same.
2054 * ports.c (scm_markstream): Same.
2055 (void_port_ptob): Specify zero for our marking function.
2056 * debug.c (debugobjsmob): Same.
2057 * dynwind.c (guardsmob): Same.
2058 * filesys.c (dir_smob): Same.
2059 * fluids.c (fluid_smob): Same.
2060 * fports.c (scm_fptob, scm_pipob): Same.
2061 * mallocs.c (mallocsmob): Same.
2062 * regex-posix.c (regex_t_smob): Same.
2063 * smob.c (freecell, flob, bigob): Same.
2064 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2065 * throw.c (jbsmob, lazy_catch_funs): Same.
2067 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2069 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2070 scm_copy_tree on code in order not to let memoized code to leak
2071 out. Thus, scm_copy_tree needs to copy vectors as well since
2072 quasiquote can introduce evaluated code also inside vector
2075 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2077 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2079 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2080 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2083 * unif.c: Say that ivect and uvect are of type signed and unsigned
2084 long instead of int in commentary so that it correctly describes
2087 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2089 * stime.c: Removed declaration of strptime. (It should be
2090 declared by the system headers. If it turns out that some systems
2091 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2093 * stime.h: Renamed TIMEH --> STIMEH
2095 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2096 to increase portability, don't use structure assignment.
2097 (Thanks to Nicolas Neuss.)
2099 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2101 (finalize_fd_sets): Added empty statement after last case label.
2102 (Thanks to Nicolas Neuss.)
2104 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2107 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2109 * init.c, readline.c: OK, I won't have these readline.x bug
2110 reports anymore. We've had them since April. The current reason
2111 is a completely unintelligible failure of totoro.red-bean.com to
2112 do the test for rl_getc_function in libreadline correctly. This
2113 kludge overrides the test if we're on totoro so that the snapshot
2114 generation process can work.
2116 * readline.c: Define a strdup replacement if not existent on system.
2118 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2120 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2121 This change makes scm_make_vector R5RS compatible. We cannot keep
2122 the third argument since people want to be able to deduce the form
2123 of the C function call only by looking at R5RS. (At the same time
2124 we have removed some unnecessary complexity!)
2126 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2127 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2128 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2129 argument in call to scm_make_vector.
2131 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2133 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2134 This macro is useful in applications.
2136 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2138 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2139 (scm_parse_path, scm_search_path): New Scheme level procedures.
2141 * load.h (scm_internal_parse_path, scm_parse_path,
2142 scm_search_path): Declared.
2144 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2146 * filesys.c (dirname, basename): New procedures.
2148 * init.c (scm_boot_guile_1): Removed condition around
2151 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2152 new data type (guards) for representation of C level guards and
2153 data on the wind chain.
2154 (scm_internal_dynamic_wind): New function.
2156 * dynwind.h: Declare scm_internal_dynamic_wind.
2158 * root.h (scm_root_state): Added scm_cur_loadp.
2160 * root.c (mark_root): Added comment about cur_loadp.
2162 * load.c: #include "dynwind.h";
2163 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2166 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2168 * ports.c (current-load-port): New procedure.
2170 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2172 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2173 not a tty, return #f.
2175 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2176 to Julian Satchell and Roland Kaufmann.)
2178 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2179 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2181 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2183 * debug.h, debug.c (scm_start_stack): New function. Implements
2184 the guts of old scm_m_start_stack.
2186 * debug.c (scm_m_start_stack): Use scm_start_stack.
2188 * init.c (scm_start_stack, scm_restart_stack): Renamed to
2189 start_stack and restart_stack. (These have static scope.)
2191 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2193 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
2194 readline functions to come in release 2.3. (Thanks to Chet
2196 (handle_errors): Use the above functions.
2198 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2200 * readline.c: Improvements for readline support: Handle errors
2201 better; Implement before-read-hook.
2203 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2205 * init.c (scm_boot_guile_1), readline.c: Test for
2206 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
2207 assure that we have version >= 2.1.)
2209 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
2211 * readline.c (scm_readline): Defer interrupts while we're calling
2214 * readline.c (scm_add_history): Bugfix: Do strdup before giving
2215 away the string to add_history.
2216 (completion_function): Do completion for readline. (Thanks to
2218 (scm_filename_completion_function): New procedure: Filename
2220 (current_input_getc): New function. Use this one instead of
2221 standard getc from readline.
2223 * throw.c, throw.h (scm_handle_by_throw): New function: This
2224 handler throws errors to next handler on the dynwind chain.
2226 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
2228 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
2231 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2233 * procprop.c (scm_i_procedure_arity): New function. Returns arity
2235 (scm_procedure_properties): Modified to return arity together with
2237 (scm_procedure_property): Added the read-only property `arity'.
2238 (scm_set_procedure_property_x): It is an error to set the `arity'
2241 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
2242 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
2244 * procprop.h (scm_sym_arity): New symbol.
2246 * objects.c (scm_set_object_procedure_x): New procedure: Use this
2247 to set the dispatch procedure of an operator or entity object.
2249 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
2250 Made procedure slots read-only.
2252 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
2253 scm_tcs_cons_gloc case in zero args switch; Fixed args
2254 construction for operators in scm_tcs_cons_gloc case in two args
2257 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2259 * fluids.c: Removed use of assert.h (in order to avoid
2262 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
2264 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
2266 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
2267 change makes the evaluator safer at the cost of evaluation speed.
2268 It handles the case when the user has added a non-immediate
2269 improper end of the application form, e.g., `(+ 0 . x)'.
2270 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
2271 minimize the extra cost as much as possible. The new code is
2272 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
2273 problem with structs planted directly in the code (e.g. by a
2274 macro). This no longer causes segmentation fault. (Thanks to
2277 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
2278 arg `proc' in order to be able to throw errors; New argument
2281 * Removed extra #include "debug.h"
2283 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
2285 * scmsigs.c: Declare usleep as returning void on some systems.
2286 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
2289 * coop.c (usleep): Return void on some systems.
2291 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2293 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
2295 * coop.c: Changed return type of usleep to int.
2297 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
2298 isn't found in the OS.
2300 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
2301 isn't enabled. (Thought that I had made this change ages ago...)
2303 * iselect.c: Declare bzero if not defined by OS.
2305 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2307 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
2308 condition. (Thanks to John Tobey.)
2310 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
2311 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
2314 * __scm.h: Start the long-term project of moving to POSIX threads.
2315 Phase 1: Classification of all critical sections.
2316 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
2317 for A sections. (See comments in __scm.h for details.)
2319 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
2320 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
2322 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2324 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
2325 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
2326 (libpath.h, versiondat.h): Replaced dependency on Makefile with
2327 dependencies on $(srcdir)/Makefile.in
2328 $(top_builddir)/config.status in order to avoid circularity.
2330 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
2331 from argc if argc was 0 initially.
2333 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
2334 in generation of libpath.h.
2336 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
2338 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
2339 libguile from 2 to 3.
2341 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
2343 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
2345 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
2347 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
2348 scm_set_port_column_x, scm_port_filename,
2349 scm_set_port_filename_x): Removed optional arguments. Added
2350 proper argument checking.
2352 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
2353 stack size in machine words.
2355 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
2356 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
2357 to Ole Myren Röhne.)
2359 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
2361 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
2362 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
2364 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
2367 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
2368 procedure apply: Copy argument lists before pushing them unto the
2369 environment so that the environment won't get mutated due to
2370 manipulation of procedure arguments. This should perhaps be
2371 regarded as a temporary solution until someone finds a more
2372 efficient one. (Thanks to Maciej Stachowiak.)
2374 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
2376 * script.c (scm_compile_shell_switches): Use "guile" as default
2377 zero arg if argc is NULL.
2379 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
2381 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
2382 is zero. (Thanks to Dirk Herrmann.)
2384 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
2386 * ports.c (scm_add_to_port_table): First line is now line 0
2387 (was 1). (Interface changed according to suggestion by Per
2390 * backtrace.c (display_header): Add 1 to line and column numbers
2391 when presenting them to the user.
2393 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
2394 from debug.c --> eval.c
2396 * eval.h, eval.c (scm_eval_options_interface): New options
2398 (SCM_EVAL_STACK): New option: Size of newly created stacks,
2399 i.e. stacks for new threads.
2401 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
2403 * eval.c (unsafe_setjmp): Removed with #if 0.
2405 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
2408 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
2409 to avoid compiler warnings.
2411 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
2413 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
2415 * throw.c (handler_message): Print message on current error port
2416 instead of default error port. (Thanks to Maciej Stachowiak.)
2418 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
2420 * ports.c (scm_add_to_port_table): allocate in units of
2421 struct scm_port_table *, not struct scm_port_table.
2422 * posix.c (scm_close_pipe): remove the port from the port table
2424 Thanks to Rob Engle for both fixes.
2426 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2428 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
2429 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
2431 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2433 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
2435 * backtrace.c (display_error_body, display_backtrace_body),
2436 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
2437 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
2438 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
2439 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
2442 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
2443 don't receive the jmpbuf arg anylonger.
2444 (scm_catch): Don't accept a #f tag.
2445 (scm_throw): Check that key is a symbol.
2446 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
2448 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
2450 * async.c (async_pending): Removed declaration.
2452 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2454 * dynwind.c (scm_wind_chain): New debug function.
2456 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
2457 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
2458 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
2459 extra layer of functions around the body and handler of a thread.
2460 This extra layer makes sure that the handler is called in the
2461 dynamic context of the surround (= empty dynwind list), but under
2462 the *dynamic root* of the body. We can not use the dynamic root
2463 of the surround since that root belongs to another thread => stack
2464 is not handled correctly. It may seem ugly to use this extra
2465 layer, but the extra cost in terms of execution time is really
2466 negligible compared to the total amount of time required to create
2467 a thread, and it would reduce maintainability to duplicate the
2468 crucial and complicated steps performed by cwdr.
2470 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
2471 (SCM_ALLOW_INTS): Added thread switching code before interrupts
2472 get re-enabled. The important effect of this is that interrupts
2473 are blocked during thread switching so that thread data structures
2474 don't risk getting messed up by an unfortunate signal.
2475 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
2476 seems to do more aggressive optimization which actually move
2477 instructions around in these macros in a fatal way. Therefore:
2478 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
2479 just superstitious...)
2480 (SCM_TICK): Maybe do a context switch and take care of asyncs.
2481 This macro should be used instead of SCM_ASYNC_TICK since the
2482 latter doesn't do context switches any more.
2484 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
2485 instead of SCM_ASYNC_TICK.
2487 * coop.c, iselect.c: Since thread switches are now performed with
2488 interrupts masked, we can't use the old mechanism of delivering
2489 signals immediately when they arrive. Signals must instead be
2490 delivered when the asyncs run *after* the end of the critical
2491 section in scm_internal_select. But this also means after context
2492 switch so that the signal will be delivered to a different thread.
2493 To avoid this, I have changed the protocol of
2494 coop_wait_for_runnable_thread and friends so that they are allowed
2495 to return the original thread. So, if a signal arrives during
2496 scm_internal_select, we won't any longer be forced do a context
2497 switch, but can remain in the same thread and deliver the signal
2500 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
2501 scm_asyncs_pending and made it global.
2503 * iselect.c: Small fixes.
2505 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
2506 coop_condition_variable_init, coop_condition_variable_wait,
2507 coop_condition_variable_signal): Changed return type from `void'
2508 to `int'. This is to adhere closer to the pthreads interface.
2509 This, in turn, is part of an attempt to provide C versions of the
2510 mutex and condition variable primitives which can be part of a
2511 frontend to COOP or pthreads.
2513 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
2514 coop_condition_variable_destroy): New functions.
2516 * coop-threads.c (scm_wait_condition_variable): Use
2517 coop_condition_variable_wait_mutex.
2519 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
2520 Definitions moved to coop-defs.h.
2522 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
2523 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
2524 scm_cond_destroy): New C interface to mutecis and cond vars.
2526 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2528 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
2530 * iselect.c: Now several threads can wait on the same file
2531 descriptor. The behaviour is compatible with OS select: All
2532 threads waiting for the fd return with the same status.
2534 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2536 * coop-threads.c, threads.h (scm_spawn_thread): New function.
2537 Can spawn a thread from application C code.
2539 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2541 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
2542 gh_doubles2scm): New functions.
2544 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
2546 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
2547 commented-out version of gh_eval_str()
2549 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
2551 * socket.c (scm_bind): free soka after use.
2553 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
2555 * stime.c (tzvar): new variable.
2556 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
2557 avoid memory leaks when allocating.
2559 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
2561 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
2564 * gc.c, tags.h: Doc fixes.
2566 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2568 * eval.c (macro-eval!): Removed. This function was a design bug.
2569 It allowed memoized code to leak out to the scheme level. Most
2570 things that you could do with `macro-eval!' can be done with
2573 1997-12-20 Tim Pierce <twp@skepsis.com>
2575 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
2576 scm_fgets now depends on ftell(3) to know how many bytes were
2579 1997-12-15 Tim Pierce <twp@skepsis.com>
2581 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
2582 dealing with strings.
2584 1997-12-13 Tim Pierce <twp@skepsis.com>
2586 Make %read-line more suitable for implementing read-line efficiently.
2587 * ioext.c (scm_read_line): Strip the terminating newline from a
2588 string, and return a cons of the string and its terminator.
2590 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
2591 of the string that is read is stored in this memory location.
2592 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
2593 * genio.c, genio.h (scm_do_read_line): Update caller.
2594 * ports.h (scm_ptobfuns): Update typedef.
2595 * fports.c (scm_fptob, scm_pipob): Update struct.
2597 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2599 * filesys.c (set_element): Return file descriptor.
2600 (fill_select_type): Return the highest file descriptor.
2601 (scm_select): Tell select about the highest file descriptor. On
2602 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
2603 Therefore the extra overhead for calculating the maximum fd seems
2604 to be more than compensated. Is this correct? In any case,
2605 scm_internal_select will be much faster with this info.
2606 (scm_select, fill_select_type, set_element): Don't accept any kind
2607 of object in the file descriptor list or vector.
2609 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2611 * iselect.c (finalize_fd_sets): Bugfix.
2613 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2615 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
2616 when using scm_internal_select (since we might switch to another
2619 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2621 * simpos.c (scm_system): always define: use sysmissing if not
2622 available. Check for HAVE_SYSTEM instead of _Windows (does
2623 Windows lack system or does it have an unusable one?).
2624 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
2625 Let the argument be optional: if not supplied, call system(NULL).
2627 * ports.c (scm_close_port): relax the type check from OPPORTP to
2628 PORTP; closing a closed port is allowed.
2630 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
2632 * fports.c (scm_fgets): Return if the last char in a chunk is
2633 newline. When fgets returns a string whose length is `size-1', it
2634 is ambiguous whether a whole line was retrieved, so we must check
2635 explicitly whether a line terminator is present.
2637 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2639 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
2640 before taking the CDR. (Thanks to Harald Meland.)
2642 * filesys.c (scm_stat): Slightly optimized.
2644 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
2646 * ports.c (scm_close_port): Make sure the port is open before
2649 * guile-snarf.in: Pass args through to gcc in a way that preserves
2650 whitespace boundaries. (Thanks to Greg Badros.)
2652 1997-12-02 Tim Pierce <twp@skepsis.com>
2654 * stacks.c (scm_frame_procedure): Reverse the logic in the return
2655 statement. (Thanks to Doug Evans for pointing this out.)
2657 1997-12-01 Tim Pierce <twp@skepsis.com>
2659 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
2661 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
2663 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
2664 errno macro expansion of this field name. (errno is a C
2665 preprocessor macro on some systems.)
2667 1997-11-29 Tim Pierce <twp@skepsis.com>
2669 * iselect.c: Doc fix.
2671 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
2673 * init.c (scm_start_stack): Removed initialization of
2674 scm_the_last_stack_var.
2676 * backtrace.h: Declare scm_the_last_stack_var.
2678 * backtrace.c: Define scm_the_last_stack_var.
2680 * root.c (mark_root): Don't mark the_last_stack_var.
2682 * root.h (scm_root_state): Removed the_last_stack_var.
2684 * throw.c: Added #include "fluids.h"
2685 (ss_handler): `the-last-stack' is now a fluid.
2687 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
2688 --> the_last_stack_fluid.
2690 * backtrace.c: Added #include "fluids.h"
2691 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
2692 (scm_backtrace): `the-last-stack' is now a fluid.
2694 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
2695 after scm_init_fluids.
2697 1997-11-28 Tim Pierce <twp@skepsis.com>
2699 * iselect.c: #ifdef USE_THREADS around thread-related includes.
2701 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
2702 DLSYM_ADDS_USCORE to decide whether to add an underscore.
2704 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2706 * iselect.c (coop_next_runnable_thread,
2707 coop_wait_for_runnable_thread): Disable interrupts so that no
2708 async is executed before a potential error_revive.
2709 (scm_internal_select): Disable interrupts during the parts of the
2710 code which manipulate the sleep queue and the file descriptors.
2712 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2714 * Makefile.am: Added iselect.c and iselect.h.
2716 * coop.c (coop_qinit): Initialize fields used by
2717 scm_internal_select.
2718 (coop_qget, coop_qget, coop_tmp_queue): Made global.
2719 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
2720 replacement in iselect.c.
2721 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
2722 coop_join): If GUILE_ISELECT enabled, use
2723 coop_wait_for_runnable_thread instead of
2724 coop_next_runnable_thread.
2725 (usleep, sleep): New replacements for system functions if
2726 GUILE_ISELECT is enabled.
2728 * coop-threads.h: Declare coop_wait_for_runnable_thread.
2730 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
2732 * filesys.c: Added #include "iselect.h". Moved FD-macros to
2733 iselect.h. Implement Scheme level `select' using
2734 scm_internal_select. (See NEWS.)
2736 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
2738 * init.c: Call scm_init_iselect.
2740 * iselect.h, iselect.c: New files. Implements
2741 scm_internal_select. (See NEWS.)
2743 1997-11-27 Tim Pierce <twp@skepsis.com>
2745 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
2746 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
2747 and scm_must_free, since ultimately the string returned will be copied
2748 by scm_makfrom0str anyway. Also, read any characters that may have
2749 been pushed onto the port with scm_ungetc.
2750 * ports.c (scm_generic_fgets): Same as for scm_fgets.
2751 * ioext.c (scm_read_line): Free string after Guilifying it.
2752 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
2754 1997-11-26 Anthony Green <green@hoser.cygnus.com>
2756 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
2758 * gh.h: Safely wrap prototypes for c++ usage.
2760 1997-11-25 Mark Galassi <rosalia@cygnus.com>
2762 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
2763 gh_repl (argc, argv).
2765 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
2767 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
2768 and to invoke scm_shell().
2769 (gh_launch_pad): took out the loading of boot-9.scm from here,
2770 since it is probably best to let the user control that. In fact,
2771 gh_repl() now invokes scm_shell() which does that.
2773 1997-11-23 Mark Galassi <rosalia@cygnus.com>
2775 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
2778 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

2781 yesterday's underscore patch. (Thanks to Marius Vollmer for
2784 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
2786 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
2787 DLSYM_ADDS_USCORE is not defined.
2789 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
2791 * gh_data.c (gh_uniform_vector_length):
2792 (gh_uniform_vector_ref): started implementing the uniform types in
2795 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
2797 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
2798 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
2800 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
2802 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
2803 configure.in was changed).
2805 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
2807 * Makefile.am (modinclude_HEADERS): Include readline.h here.
2808 * Makefile.in: Regenerated.
2810 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
2812 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
2813 OPORT is an `open' port, not an output port.
2815 * filesys.c (scm_close, set_element, get_element, scm_chown,
2816 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
2817 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
2818 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
2819 scm_close_port, scm_port_line, scm_set_port_line_x,
2820 scm_port_column, scm_set_port_column_x, scm_port_filename,
2821 scm_set_port_filename_x, scm_port_mode,
2822 scm_close_all_ports_except, scm_set_current_output_port,
2823 scm_set_current_error_port): Likewise
2824 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
2825 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
2827 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
2828 * backtrace.c (display_backtrace_body): Likewise
2829 * fports (scm_setvbuf): Likewise
2830 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
2831 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
2832 scm_getpeername, scm_send, scm_sendto): Likewise
2833 * unif.c (scm_uniform_array_write): Likewise
2835 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
2837 Minor problems with substring-related tag changes.
2838 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
2839 exactly what we want to leave in to detect substrings.
2840 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
2841 * tags.h: Fix diagrams and comments describing the S tag bit;
2842 remove vestigial remarks about the D tag bit.
2843 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
2844 * strings.c: Formatting tweaks.
2846 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
2847 variable first; then SCHEME_LOAD_PATH, with a warning message.
2848 (scm_parse_path): New function.
2849 * script.c: Doc fixes.
2851 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
2853 Readline support, from Daniel Risacher.
2854 * readline.c, readline.h: New files.
2855 * init.c: #include "readline.h".
2856 (scm_boot_guile_1): Call scm_init_readline, if we have it.
2857 * Makefile.am (libguile_la_SOURCES): Include readline.c.
2858 * Makefile.in: Regenerated.
2859 * scmconfig.h.in: Regenerated, after change to ../configure.
2861 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
2863 * gh.h: gh_vector_set -> gh_vector_set_x
2865 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
2867 * gh_data.c (gh_vector_set_x): changed name to make it consistent
2868 with the ! -> _x mapping when going from Scheme to C.
2870 1997-10-19 Mark Galassi <rosalia@cygnus.com>
2872 * gh.h (gh_reverse):
2880 (gh_assoc): added these gh_ functions implemented as macros.

2883 (gh_string_equal_p): added these two missing predicates.
2885 * gh_list.c (gh_append):
2890 (gh_set_cdr_x): added these routines as I go through and try to
2891 complete the picture R4RS functions that should be mirrored in the
2894 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2896 * tags.h (scm_tc7_substring): Changed the comment and code to
2897 conform with the changes below. Folks! We have suddenly two new
2898 free tc7 codes!!! Jummy, jummy!
2900 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
2902 * Makefile.in: Rebuilt.
2903 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
2905 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.

2922 (SCM_TYP7D): Removed.
2923 (scm_tc7_mb_string): Removed.
2924 (scm_tc7_mb_substring): Removed.

2927 Don't include "mbstrings.h".
2928 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
2929 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
2931 Don't include "mbstrings.h".
2932 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
2933 (SCM_SYMBOL_SLOTS): Define as 4.
2934 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

2955 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
2956 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
2958 1997-10-12 Mark Galassi <rosalia@cygnus.com>
2960 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
2962 * gh_test_c.c (c_vector_test): some improvements on the vector
2965 * gh.h (gh_vector): this used to exist but do the wrong thing.
2966 Now it (almost) does the right thing, though it takes a list
2967 instead of the individual arguments. I need to see how it could
2969 (gh_list_to_vector): added this function as a macro. Corresponds
2970 to Scheme's (list->vector ...).
2971 (gh_vector_to_list): added this function as a macro. Corresponds
2972 to Scheme's (vector->list ...).
2974 * gh_data.c (gh_vector_ref): renamed from gh_vref to
2975 gh_vector_ref, so that it resembles the Scheme routines more.
2976 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
2977 resembles the Scheme routines more.
2978 (gh_make_vector): this used to be (stupidly) called gh_vector().
2979 This is the right name, since it does the same thing as the Scheme
2980 (make-vector ...) procedure.
2982 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
2984 * ports.h: #include "libguile/print.h"
2986 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
2987 Some indentation fixes.
2989 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
2990 longer a user field; New field: class_flags.
2992 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
2994 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>

2997 gh_int2scmb(), which is now tagged as obsolete.
2999 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3001 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3002 macros should by convention not test for NIMPness.)
3003 (SCM_COERCE_OPORT): Adjust indentation.
3005 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3006 SCM_NIMP test before SCM_PRINT_STATE_P.
3008 * struct.c, struct.h, gc.c: Renamed:
3009 scm_struct_i_layout --> scm_vtable_index_layout
3010 scm_struct_i_vcell --> scm_vtable_index_vcell
3011 scm_struct_i_vtable --> scm_vtable_index_vtable
3012 scm_struct_i_printer --> scm_vtable_index_printer
3013 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3015 * struct.c (scm_print_struct): Use new printer slot; Default
3016 printing: Also output hex code of vtable so that type identity
3017 will be indicated as well.
3018 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3019 Removed struct_printer_var; Removed struct-vtable-offset;
3020 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3021 vtable-offset-user): New constants.
3023 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3024 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3025 If this slot contains a procedure, use that to print structures of
3026 the type represented by this vtable.
3028 * print.c (scm_iprin1): Don't print arguments of macro
3029 transformers. (They are always: exp env.); Bugfix: Unmemoize
3030 transformer source with correct environment.
3032 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3034 Streamlining of call-with-dynamic-root:
3036 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3037 there is now only one catch.
3038 (cwdr_outer_body): Removed.
3039 (cwdr_handler): New function.
3040 (scm_internal_cwdr): New function to perform the function of cwdr
3041 but take args that are more useful to C code. Also, the handler
3042 is now invoked *outside* of the new dynamic root, like the docs
3043 say. We no longer have to catch absolutely all errors, the caller
3044 is responsible for using a handler that does not throw, if he
3046 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3047 * root.h (scm_internal_cwdr): New prototype.
3049 Even more but risky streamlining:
3051 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3052 allocation of the jumpbuf of a root continuation. The changes
3053 below are controlled by it. They are now deactivated.
3054 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3055 the JMPBUF of the scm_rootcont to NULL before returning.
3057 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3058 when they are non-NULL.
3059 (scm_gc_mark): Likewise, mark only when non-NULL.
3061 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3062 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3064 * gc.c (scm_done_malloc): New function.
3065 gc.h (scm_done_malloc): New prototype.
3067 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
3068 (struct scm_print_state) [revealed]: New field.
3069 (scm_print_state_vtable): Make visible to the outside world for
3070 type checking purposes.
3071 (scm_valid_oport_value_p): New prototype.
3073 * print.c (scm_valid_oport_value_p): New function to check whether
3074 a certain value is acceptable as a port argument.
3075 (scm_print_state_vtable): New variable.
3076 (scm_free_print_state): Set `revealed' field to false.
3077 (scm_iprin1): Call user supplied closure printer with
3078 scm_printer_apply. Print in the traditional way when there isn't
3079 one or when it returns #f.
3080 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3081 Accept a port/print-state pair in addition to just a port.
3082 (scm_prin1): Don't return the print_state to the pool when it has
3084 (scm_printer_apply): Set `revealed' field of print_state to true.
3085 (scm_init_print): Set scm_print_state_vtable.
3086 (print_state_fluid, print_state_fluid_num): Removed.
3088 * throw.h (scm_handle_by_proc_catching_all): New prototype
3089 throw.c (scm_handle_by_proc_catching_all): New function
3091 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3093 * Makefile.in: Regenerated with automake 1.2c.
3095 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3097 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3098 was looping endlessly.
3100 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3102 * strports.c (scm_eval_string): Don't close the port.
3104 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3105 former returns a nice normal integer. (Thanks to Daniel
3108 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3110 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3111 makefile variable as a build parameter called LIBS. The
3112 build-guile program will use this, for the time being.
3113 * Makefile.in: Regenerated.
3115 Thanks to Shiro Kawai:
3116 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3117 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3120 * Makefile.in: Regenerated with automake 1.2a.
3122 * script.c (scm_compile_shell_switches): If we hit the -c or --
3123 arguments, don't set the car of (command-line) to scm_usage_name,
3124 the prettified name of the guile executable; give it the full
3125 path, the way shells usually handle $0.
3127 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3129 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3130 Scheme-level name `array-map' and renamed `serial-array-map' to
3131 `serial-array-map!'.
3133 * backtrace.c: Introduced exception handlers which now enclose
3134 `display-error' and `display-backtrace' so that error reporting
3135 won't get into infinite loops if an error occurs during displaying
3136 of the error. This can very easily happen with user supplied
3137 print call-back routines.
3139 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3141 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3142 the names `serial-array-map' and `array-map' should be removed.)
3144 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3146 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3147 Added #include "objects.h"
3149 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3150 Add #include "feature.h".
3152 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3153 (modinclude_HEADERS): Added objects.h.
3155 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3156 This test is needed at many places in the code and should be
3157 abstracted. (Motivated by the need of this test in libguiletk.)
3159 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3160 (scm_eval_string), load.c (scm_primitive_load,
3161 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3162 Use SCM_EOF_OBJECT_P.
3164 * eval.c (scm_init_eval): Add feature `delay'.
3166 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3168 * scmhob.h: Removed.
3170 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3172 * list.h (SCM_LISTn): New macros. Make list creation in C code
3173 prettier. The idea comes from STk.
3175 * sequences.h, sequences.c, append.h, append.c: Removed. These
3176 files implemented non-R4RS operations which would encourage
3177 non-portable programming style and less easy-to-read code.
3179 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3182 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3183 sequences.h, #include append.h.
3185 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
3188 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
3190 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
3192 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
3194 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3196 * eval.c: Added #include "objects.h"
3198 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
3201 * smob.c (scm_smob_prehistory): Create two objectsmobs with
3202 adjacent smob numbers.
3204 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3206 * procprop.h: Added declaration of scm_i_inner_name.
3208 * gsubr.c: New global symbol scm_i_inner_name.
3210 * debug.c (scm_procedure_name): Try procedure property
3211 `inner-name' if `name' fails.
3213 * print.c (scm_iprin1): Use scm_macro_name.
3215 * eval.c (scm_m_define): Give names to macros as well; Only the
3216 first top-level definition gives a procedure/macro a name.
3217 Otherwise confusing names can turn up in backtraces.
3218 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
3219 `name'; Give names to macros as well.
3221 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
3222 (scm_macro_transformer): Use SCM_CLOSUREP instead of
3225 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3227 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
3229 (prinmacro): Removed. The code has been moved/merged into print.c
3230 in order to decrease code redundancy. We want macros to print in
3231 a way equivalent to procedures, and it would be silly to duplicate
3232 the required code. (We don't want to maintain two places.)
3233 (macrosmob): Print field is now a NULL pointer.
3235 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
3236 scm_macro_transformer): New prototypes.
3237 (scm_tc16_macro): Declared.
3239 * print.c (scm_iprin1): Added code for printing of macros. Macros
3240 are now printed in a way equivalent to procedures.
3242 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
3244 * procs.h (scm_closure_p): Added declaration.
3246 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3248 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
3249 Shouldn't pass "heap" as the subr name.
3251 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
3253 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
3254 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
3255 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
3256 gh_equal_p): Use SCM_NFALSEP, instead of testing against
3257 SCM_BOOL_T. Any non-false value is true.
3259 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3261 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
3262 scm_gensym): Added prototypes.
3264 * symbols.c (scm_gensym): New function. This will speed up
3265 certain types of applications (such as macro systems) which
3266 generate lots of symbols.
3268 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3270 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
3272 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
3274 * unif.c (scm_shap2ra): tighten the checking of the array dimension
3275 specifier, since (2) or (2 . 3) would cause SEGV.
3276 (scm_transpose_array): more argument checking fixes.
3278 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
3280 * Makefile.in: Regenerated.
3282 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
3284 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
3286 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3288 * error.c, error.h (scm_error_callback): Removed (see NEWS).
3290 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
3292 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
3293 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
3296 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
3297 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
3298 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
3299 scm_array_p, scm_array_rank, scm_array_dimensions,
3300 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
3301 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
3302 scm_array_prototype): Added case scm_tc7_wvect.
3304 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
3306 * errno.h: prototype for scm_strerror.
3307 * error.c (scm_strerror): new procedure.
3309 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3311 * list.c (scm_list_append_x): Allow non-pair as last argument.
3312 This is consistent with the R4RS append and is probably the
3313 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
3315 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
3317 * stime.h: prototype for scm_times.
3318 * stime.c (scm_times): new procedure.
3319 * ioext.c (scm_fseek): if the first argument is a file descriptor
3321 (scm_ftell): if the first argument is a file descriptor call lseek
3323 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
3324 * filesys.c (scm_chmod): if the first argument is a file descriptor,
3326 (scm_chown): if the first argument is a port or file descriptor,
3328 (scm_truncate_file): new procedure.
3329 Add DEFER/ALLOW INTS to a few other procedures.
3330 (scm_fsync): new procedure.
3331 (scm_open_fdes): new procedure.
3332 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
3334 (scm_fcntl): the first argument can now be a file descriptor. The
3335 third argument is now optional.
3337 * posix.c (scm_execl, scm_execlp): make the filename argument
3338 compulsory, since omitting it causes SEGV.
3339 (scm_sync): return unspecified instead of #f.
3340 (scm_execle): new procedure.
3341 (environ_list_to_c): new procedure.
3342 (scm_environ): use environ_list_to_c. disable interrupts.
3343 (scm_convert_exec_args): take pos and subr arguments and
3344 improve error checking.
3346 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3348 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
3349 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
3350 argument to SCM_ASSERT. Furthermore, the name of the function
3351 should be passed as first argument when signalling
3352 SCM_WNA. (Thanks to Thomas Morgan)
3354 * gsubr.c (scm_gsubr_apply): From Radey Shouman
3355 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
3356 dispatches on the number of actual args has a default case
3357 reporting an internal error. This is a vestige from a version
3358 that mallocated a SCM vector to hold the arguments. In the
3359 current version this check is too late: if it ever happens we will
3360 have already overstepped the bounds of the array.
3362 Also, the patch [...] adds a check for too many actual arguments."
3364 mdj: Removed check for "internal programming error".
3366 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3368 * gh_io.c (gh_write): New function.
3370 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
3371 throw.c (scm_internal_stack_catch): New sibling to the other catch
3372 functions. Code moved from gh_eval.c.
3373 throw.h: Added header.
3374 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
3375 scm_internal_stack_catch.
3377 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3379 * ioext.h: fix up prototypes.
3380 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
3381 Scheme name is now dup->fdes.
3382 (scm_dup_to_fdes): make the second argument optional and
3383 fold in the functionality of scm_primitive_dup.
3384 (scm_primitive_dup): deleted.
3386 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
3388 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
3389 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
3390 ultrix are defined. Use setvbuf instead of setbuf.
3391 (scm_setvbuf): new procedure.
3392 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
3393 (scm_setfileno): moved from ioext.c.
3394 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
3395 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
3397 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
3399 * fluids.c (scm_fluid_p): New function.
3400 * fluids.h (scm_fluid_p): New prototype.

3404 * print.c (scm_iprin1): Enter printed structures into the print
3405 state as nested data while they are printed.
3406 (print_state_fluid, print_state_fluid_num): New variables.
3407 (scm_init_print): Initialize them.
3408 (scm_iprin): If print_state_fluid carries a print_state, use that
3409 instead of creating a new one.
3410 (scm_printer_apply, apply_stub, struct apply_data): New
3411 definitions to help with calling printer functions written in
3413 * print.h (scm_printer_apply): New prototype.
3415 * struct.c (scm_print_struct): Use scm_printer_apply to call the
3416 user defined struct printer.
3418 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
3419 * fluids.h (scm_internal_with_fluids, scm_with_fluids,
3420 scm_swap_fluids, scm_swap_fluids_reverse): New prototypes.
3421 * fluids.c (scm_internal_with_fluids, scm_with_fluids,
3422 scm_swap_fluids, scm_swap_fluids_reverse): New functions.
3424 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
3426 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
3427 SCM_ASSERT: arg comes before pos.
3429 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3431 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
3432 to a list of length zero correctly.
3434 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
3436 Supply an `fgets' method for port objects to do fast line i/o.
3437 * ioext.c (scm_read_line): New function.
3438 * genio.c (scm_gen_read_line): New function.
3439 * fports.c (scm_fgets): New function.

3448 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
3450 * ioext.h: removed scm_duplicate_port prototype.
3452 * ioext.c (scm_primitive_dup2): return the new file descriptor
3453 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
3455 (scm_fdopen): bug fix: don't try to make port unbuffered until its
3456 stream has been set.
3457 (scm_duplicate_port): deleted, there's now an implementation in
3459 (scm_primitive_dup2): do nothing if newfd == oldfd.
3461 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
3463 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
3466 * ioext.h: new prototypes.
3467 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
3469 * fluids.c (next_fluid_num): don't do
3470 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
3472 * ports.h: prototypes too.
3473 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
3475 * fports.h: prototype too.
3476 * fports.c (scm_evict_ports): moved from ioext.c.
3478 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
3480 * ports.c (scm_close_port): return a boolean instead of unspecified.
3481 throw an error if an error other than EBADF occurs.
3483 * filesys.h: scm_close prototype.
3484 * filesys.c (scm_close): new procedure, can close file descriptors
3485 and ports (scsh compatible).
3487 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
3490 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
3492 * fluids.c, fluid.h: New files.
3493 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
3494 (modinclude_HEADERS): Added "fluids.h"
3496 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
3497 scm_init_fluids to initialize the fluid machine.
3498 (scm_start_stack): Initialize the fluids of the first root with
3499 scm_make_initial_fluids.
3501 * root.h: Added "fluids" member to scm_root_state.
3502 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
3503 (scm_make_root): Call scm_copy_fluids to make fluid bindings
3504 unique for the new root when it has a parent.
3506 * smob.h: Include "libguile/print.h" to make scm_print_state
3509 * dynl.c (free_dynl_obj): New function to free the dynamic object
3510 data. (dynl_smob): Use it.
3511 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
3512 the dynamic object data below the linking of the object to avoid
3513 memory leak when the linking code throws an error. Now the code
3514 leaks a whole dynamically linked library when must_malloc throws,
3515 but that should be much less likely.
3517 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
3519 Changes to compile under gnu-win32, from Marcus Daniels:
3520 * stime.c (tzset): If tzset isn't provided, make it a NOP.
3521 (scm_localtime): Change SCM_EOF to SCM_EOL.
3522 (scm_mktime): Likewise.
3523 * socket.c: Don't include sys/un.h unless autoconf tells
3524 us Unix domain sockets are available.
3525 (scm_fill_sockaddr): Ignore Unix domain code.
3526 (scm_addr_vector): Likewise.
3527 (scm_init_addr_buffer): Likewise.
3528 (scm_socketpair): Don't include unless socketpair was
3529 found during autoconf.
3530 * simpos.c (SYSTNAME): Treat cygwin like Unix.
3531 * scmsigs.c (scm_pause): Don't include unless pause was found
3533 * posix.c (scm_getgroups): Don't include unless support function
3534 was found during autoconf (in this case, getgroups).
3535 (scm_setpwent): For setpwent.
3536 (scm_setegid): For setegid.
3537 * net_db.c (scm_inet_netof): Don't include unless support
3538 function was found during autoconf (in this case, inet_netof).
3539 (scm_lnaof): For inet_lnaof.
3540 (scm_inet_makeaddr): For inet_makeaddr.
3541 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

3552 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
3553 scm_misc_error, not SCM_EOF.
3555 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
3556 arguments for formatting the error message, not SCM_BOOL_F. I
3557 think this is left over from the (eq? '() #f) days.
3559 * read.c (recsexpr): Give this a dummy definition if
3560 DEBUG_EXTENSIONS isn't #defined.
3562 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
3564 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
3567 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
3569 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
3572 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
3574 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
3575 alloca.lo will be included in @LIBLOBJS@. Something better than
3576 this should be possible.
3577 * Makefile.in: Regenerated.
3579 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
3581 * simpos.h: prototype for scm_primitive_exit.
3582 * simpos.c (scm_primitive_exit): new procedure, terminates the
3583 process without unwinding the stack.
3585 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
3587 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
3588 argument and logior its components together, so the user doesn't
3589 have to do this explicitly. Also, if regexp/basic is supplied, then
3590 turn off REG_EXTENDED.
3591 (scm_init_regex_posix): New regexp/basic symbol.
3592 (REG_BASIC): #define this if it is not already present.
3594 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
3596 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
3597 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
3598 (CLEANFILES): New target, clean versiondat.h, libpath.h.
3599 (DISTCLEANFILES): New target, clean *.x.
3600 * Makefile.in: Regenerated.
3602 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>

3605 years in usage message.
3607 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
3608 * Makefile.in: Regenerated.
3610 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
3611 flag; I don't think we support it.
3612 (scm_make_regexp): Make sure the user doesn't pass the
3615 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
3617 (scm_init_regex_posix): Define constants for the REG_mumble flags;
3618 name them according to the SCSH convention: regexp/mumble.
3620 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
3622 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
3624 * Makefile.am (libpath.h): Include the values of all the standard
3625 Makefile directory variables. Print a message, but don't print
3627 (versiondat.h): Print a message, but don't print all the commands.
3628 * load.c: #include "alist.h".
3629 (init_build_info): New function.
3630 (scm_init_load): Call it.
3631 * Makefile.in: Regenerated.
3633 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
3635 * root.c: Establish a reliable catch-all handler for the new root.
3636 After all the Scheme handler function might signal an error too,
3637 and we don't want to lose that.
3638 (cwdr_inner_body): Renamed from cwdr_body.
3639 (cwdr_outer_body): New function, to establish the user's handler,
3640 and pass control to cwdr_inner_body.
3641 (cwdr): Establish the reliable catch-all handler here, and pass
3642 control to cwdr_outer_body.
3643 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
3644 the user's handler through to cwdr_outer_body.
3645 * throw.c (scm_handle_by_message): Move guts into....
3646 (handler_message): New static function.
3647 (scm_handle_by_message_noexit): New function.
3648 * throw.h (scm_handle_by_message_noexit): New prototype.
3650 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
3651 across this. Only works on GCC. Otherwise, we hope for the best.
3652 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
3653 the feeling that real thread systems will not need this...
3655 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
3657 Try to detect when people are using one version of libguile and a
3658 different version of ice-9. People have been skewing things and
3659 sending in bug reports.
3660 * Makefile.am (versiondat.h): New file to generate.
3661 * version.c: #include "versiondat.h", to get version info.
3662 (scm_libguile_config_stamp): New function.
3663 * script.c: #include "version.h".
3664 (scm_compile_switches): Call scm_version to get version number.
3665 * scmconfig.h.in, Makefile.in: Regenerated.
3666 * Makefile.in: Regenerated.
3668 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
3669 primitive definitions under their Scheme names.
3671 * Makefile.am (libguile_la_LDFLAGS): Update library version to
3672 1:2. Helps avoid confusion between installed and uninstalled libs.
3674 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
3677 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
3678 backslash from definition; this should be used like: GDB_INTERFACE;
3680 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3682 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
3683 new port unbuffered until its stream has been set.
3685 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
3687 * ports.h: new prototype.
3688 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
3690 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
3692 Make things compile neatly under Sun's C compiler.
3693 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
3694 * extchrs.c (xmbtowc): Make the second arg a normal char, not
3695 unsigned, because that's what the ANSI function takes.
3696 * extchrs.h (xmbtowc): Corresponding change to prototype.
3697 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
3699 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
3700 argument plain char *.
3701 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
3703 * tag.c (scm_tag): Remove unreachable statement.
3704 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
3705 top of the word, it should be unsigned.
3707 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
3708 is defined, to avoid warnings; it's only used in the
3709 conflict-checking code. Which might go away anyway.
3710 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
3711 conditionals; put the label definition in an #if too, to stifle
3714 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
3715 ChangeLog-threads in the distribution.
3716 * Makefile.in: Regenerated.
3718 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
3720 * guile-snarf.in: Changed regexp to support CPPs that insert
3721 whitespace between lexical tokens (which munges the `%%%' snarf
3724 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
3726 * load.c (scm_init_load_path): Append $(datadir)/guile to
3727 %load-path, so modules do not have to be installed in Guile's
3728 current version directory.
3730 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
3732 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
3733 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
3734 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
3735 call the sysdep functions with deferred ints.
3736 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
3737 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
3738 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
3741 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
3744 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
3746 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
3748 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
3750 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
3753 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
3755 * eval.c (scm_lookupcar1): New procedure to cope with a race
3756 condition during lookup (when using threads).
3757 (scm_lookupcar): Implement in terms of scm_lookupcar1.
3758 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
3761 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
3763 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
3764 supplied. (Change from Tim Pierce.)
3766 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
3768 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
3769 23:47:01 1997" changelog: Slots are now initialized with `#f' by
3770 default and not `()'. `#f' is the canonical non-value in Scheme,
3773 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
3775 * struct.c (struct_printer): New variable that holds a handle on
3776 the Scheme variable *struct-printer*. This variable can be set by
3777 Scheme code to override the printing of structures.
3778 (scm_print_struct): If struct_printer is set, call it. If it is
3779 not set, or returns #f, print the structure in the old fashion.
3780 Include "eval.h" for scm_apply.
3782 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
3784 * struct.c (scm_struct_ref, scm_struct_set_x): Use
3785 scm_struct_i_n_words to get the number of fields, not
3786 -scm_struct_n_extra_words.
3788 On the route to fancier struct printing:
3789 * struct.c (scm_print_struct): New function to print a structure.
3790 Include "genio.h" to support it. This function doesn't do
3791 anything interesting right now, but I think it should be here
3793 * struct.h: Include "print.h" and add prototype for
3795 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
3796 print structures ourself.
3798 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3800 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
3801 before applying the handler in case it doesn't return.
3803 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
3805 * scmsigs.h, async.h: updated.
3807 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
3810 * posix.c (scm_uname): interpret only negative values as an error.
3811 Solaris normally returns a positive value.
3813 * script.c (scm_compile_shell_switches): if we are not going into
3814 an interactive repl, set scm_mask_ints to zero so that asyncs can
3817 * simpos.c (scm_system): don't ignore/unignore signals around
3820 * posix.c (scm_open_pipe): don't ignore/unignore signals around
3823 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
3824 done in boot-9.scm instead.
3826 * scmsigs.c, async.c: Major rewriting of signal handling code.
3827 (scm_sigaction): new procedure.
3828 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
3830 (scm_raise): return unspecified, throw error on failure.
3832 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
3834 * regex-posix.c (scm_init_regex_posix): Register the "regex"
3835 feature, to help boot-9.scm decide whether to import the regex
3838 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3840 * eval.c: Include scmconfig.h at the beginning of the file so that
3841 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
3844 * regex-posix.c: #include "_scm.h" before conditionally #including
3845 <regex.h>; the former defines HAVE_REGCOMP.
3847 * regex-posix.c: #include <regex.h> conditionally, so the file is
3848 CPP'able (for dependency scanning) even on systems that don't have
3851 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3853 Add new R4RS-compliant syntax for keywords.
3854 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
3855 regardless of the setting of the `keywords' read option.
3856 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
3857 can be re-read no matter what the setting of the `keywords' read
3860 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
3862 Add support for POSIX regular expressions.
3864 * regex-posix.c, regex-posix.h: New files. (Some code
3865 is taken liberally from rx/rgx.c in the old Guile dist.)
3867 * init.c: Include regex-posix.h.
3868 (scm_boot_guile_1): Call scm_init_regex_posix.
3870 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
3871 Add regex-posix.[ch] sources.
3872 * Makefile.in: Regenerated.
3874 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
3875 to do this automatically? It didn't for me, bleh.)
3877 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
3879 * fports.c (print_pipe_port): New function.
3880 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
3881 latter doesn't even take the right arguments.
3883 * Makefile.am: Increment shared lib revision number. I think
3884 sometimes the uninstalled Guile finds the installed shared lib;
3885 Gord says doing this might help. As things turned out, I can't
3886 say whether it does.
3887 * Makefile.in: Regenerated.
3889 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
3890 passing it as the closure argument to scm_boot_guile. (Bill
3893 * ports.c (print_void_port, putc_void_port, puts_void_port,
3894 write_void_port, flush_void_port, getc_void_port, close_void_port,
3895 noop0): Use ANSI prototypes instead of K&R declarations, so the
3896 initialization of void_port_ptob gets aggressively type-checked.
3897 Fix arguments of print_void_port and write_void_port. (Bill

3931 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
3933 * script.c (scm_find_executable): Use prototype-style definition
3934 here; apparently it's not quite right to have const in a prototype
3935 and then use a K&R declaration. I wonder if stuff like this will
3936 go away if we compile with -Wrequire-prototypes, or whatever that
3937 is... (Bernard URBAN)
3939 * scmhob.h: New text from Bernard URBAN.
3941 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
3943 * script.c: Don't #define const on hpux. Configure takes care of
3944 this. (Thanks to Larry Schwimmer.)
3946 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
3947 decide whether to #include <unistd.h>, instead of listing a bunch
3948 of systems. Don't #include stdio twice. Removed dyked-out
3949 definition of scm_find_impl_file.
3951 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
3953 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
3954 library version info to 1:0.
3955 * Makefile.in: Regenerated.
3957 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
3958 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,

3961 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
3962 throw.c: Update copyright years; these files have been worked on
3963 significantly in 1997, but only had copyright years for 1996.
3964 Also, change name of copyright holder on some from Mikael
3965 Djurfeldt to Free Software Foundation; he has signed papers
3966 assigning the changes to the FSF.
3968 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
3969 reason not to give the user the option.
3971 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3972 Return #f on end-of-file when scanning table (i.e. when called
3973 with no arguments). Try to catch errors, when we can.
3974 * posix.c (scm_getgrgid, scm_getpwuid): Same.
3976 * script.h (scm_shell_usage, scm_compile_shell_switches): New
3977 external declarations. These are useful.
3979 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
3981 * posix.c: don't include <sys/select.h> or define macros for
3982 select, since they were not used in this file.
3984 * filesys.c (scm_select): make the fifth parameter microseconds,
3985 not milliseconds. let the fourth parameter be either a real value
3986 or an integer or #f. The first, second and third arguments can
3987 now be vectors: the type of the corresponding return set will be
3989 (set_element, get_element): new static procedures.
3991 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
3993 * strports.c (scm_eval_string): New function.
3994 (scm_eval_0str): Trivially re-implemented in terms of
3996 * strports.h (scm_eval_string): New extern decl.
3998 * net_db.c (h_errno): Add extern decl for this.
4000 * fports.c (local_pclose): New function.
4001 (scm_pipob): Use it in the initializer here.
4004 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4005 Use a meaningful error message when signalling an error. For
4006 this, scm_gethost must check h_errno rather than errno.
4008 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4010 * Makefile.in: Regenerated, using automake-1.1p.
4012 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4014 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4015 not SCM_UNSPECIFIED.
4017 * script.c (scm_compile_shell_switches): don't append (quit) if
4019 (scm_shell): call scm_exit_status and exit on the result of the
4022 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4024 Ensure that shared substrings are handled properly when passed to
4025 a system call or other foreign function. Many thanks to Tim
4027 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4028 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4029 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4030 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
4031 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
4032 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
4033 (scm_display_error_message): use RO macros when strings may be RO.
4034 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
4035 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
4036 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
4037 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
4038 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
4039 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
4040 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
4041 scm_strftime), vports.c (scm_make_soft_port): use
4042 SCM_COERCE_SUBSTR to make sure shared substrings are
4045 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4047 * error.c (scm_error): Add newline to error message.
4049 * init.c (scm_init_standard_ports): Doc fix.
4051 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4053 * dynl-shl.c: Completely replaced with new code from Bernard
4056 * script.c (scm_ice_9_already_loaded): New variable.
4057 (scm_compile_shell_switches): Use it.
4059 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4061 * filesys.c (scm_input_waiting_p): add missing third argument to
4064 * stime.c (scm_localtime): copy the result of localtime before
4065 calling gmtime in case they share a buffer.
4066 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4069 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4071 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4073 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4075 * Makefile.am (check-local): New target, which causes 'make check'
4076 to run gh_test_c and gh_test_repl, with some trivial input.
4077 * Makefile.in: Rgnrtd.
4079 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4081 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4084 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4086 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4087 sure how this was supposed to work.
4088 (scm_async_click): don't send SCM_TICK_SIGNAL.
4089 (scm_init_async): don't initialize %tick-thunk.
4091 * the following change doesn't affect the Scheme interface:
4092 gc-thunk is called at the end of garbage collection. however it's
4093 no longer implemented by pretending it's a signal.
4095 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4096 system async corresponding to scm_gc_thunk.
4097 * async.h: declare scm_gc_async.
4098 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4099 gc-thunk directly, instead of going through a signal handler.
4100 (scm_gc_async): new variable, points to the GC system-async.
4101 (scm_init_async): save the GC async as scm_gc_async instead
4102 of using system_signal_asyncs.
4103 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4105 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
4107 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
4108 Don't screw up if we're interrupted.
4109 * Makefile.in: Regeneradet.
4111 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4113 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4115 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4116 we're not using AM_INIT_GUILE_MODULE any more.
4117 * Makefile.in: Reneregated.
4119 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4121 Functions for finding variable bindings, grace à Tim Pierce.
4122 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
4123 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
4125 Get 'make dist' to work again.
4126 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4127 * Makefile.in: Regenerated, like a surry without a fringe on top.
4129 Changes for reduced Guile distribution: one configure script,
4131 * configure.in, configure: Removed.
4132 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4133 real configure script lives.
4134 * Makefile.in, scmconfig.h.in: Regenerated.
4136 * init.c: #include "script.h", to get prototype for script.c's
4139 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4141 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4142 scm_must_malloc, not raw malloc.
4144 * script.c (scm_compile_shell_switches): Dyke out debugging output
4147 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4149 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4151 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4152 system has them. Hope this is safe. Previously
4153 sys/timeb.h was included if HAVE_FTIME was defined or if
4154 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4155 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4157 * ioext.c (scm_setfileno): add missing third argument to
4158 scm_misc_error call.
4160 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4162 * eq.c (scm_equal_p): Correctly compare strings of different
4163 varieties. (Thanks to Tim Pierce.)
4165 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4167 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4168 #! block comment must occur on a line all by itself.
4170 Move most of the guts of shell command processing into libguile,
4171 so guile.c can be very small (and eventuallly auto-generated. (I
4172 mean, generated mechanically, not self-generated. Hmm.))
4173 * guile.c, script.c, script.h: New source files.
4174 * init.c (scm_boot_guile_1): Call scm_init_script.
4175 * libguile.h: #include "script.h".
4176 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4177 targets, for new executable.
4178 (libguile_la_SOURCES): Mention script.c.
4179 (modinclude_HEADERS): Add script.h.
4180 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4181 not dynamic linking is enabled. This is because we're generating
4182 executables now. Move CY_AC_WITH_THREADS call after those, so the
4183 values of cy_cv_threads_libs captures the libs chosen above.
4184 * Makefile.in, configure, aclocal.m4: Regenerated.
4186 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
4187 We don't maintain this interface any more, and it just confuses
4190 * alloca.c: #include <scmconfig.h>, not <config.h>.
4191 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
4192 it'll get included in disties.
4194 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4196 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
4197 be distributed, because they confuse people.
4198 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
4200 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
4202 * configure.in: check for presence of gethostent (not present on
4203 OpenBSD by default).
4204 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
4205 * configure, scmconfig.h.in: Regenerated.
4207 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4209 * backtrace.c (scm_backtrace): Split message string across
4210 newlines properly. GCC is more tolerant of this than other
4213 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
4215 Merge threads directory into libguile.
4216 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
4217 threads.h: New source files.
4218 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
4219 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
4221 (modinclude_HEADERS): Add threads.h, coop-defs.h.
4222 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4223 coop-threads.c.cygnus, coop-threads.h.cygnus.
4224 * configure.in: If we're using threads, include threads.o in
4226 * _scm.h, libguile.h: threads.h lives in this directory now.
4227 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4228 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
4229 currently used, but brought along for information's sake.
4230 * ChangeLog-threads: log from old 'threads' directory.
4231 * Makefile.in, configure: Rebuilt.
4233 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
4235 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
4238 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
4240 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
4242 Merge GH interface library into libguile.
4243 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
4244 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
4245 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
4246 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
4248 (EXTRA_libguile_la_SOURCES): ... here.
4249 (pkginclude_HEADERS): Add variable, to get gh.h installed.
4250 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
4251 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
4252 New variables, describing how to build the gh test programs.
4253 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
4254 build the test programs, and we probably should have been linking
4255 libguile.la against them all along, to support AIX shared libs.
4256 Add cflags for threads to CFLAGS; add libs for threads to new
4257 variable THREAD_LIBS, used in Makefile.am.
4258 * ChangeLog-gh: log from old `gh' subdirectory.
4259 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
4261 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
4263 * acconfig.h: Undo change of Apr 9; including the definition of
4264 PACKAGE in the guile headers conflicts with applications' own
4266 * scmconfig.h.in: Regenerated.
4268 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

4274 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
4275 when PROC is receiving no arguments.
4277 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
4279 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
4280 have S_IFSOCK. This is the case under Ultrix.
4282 * posix.c (scm_status_exit_val, scm_status_exit_val,
4283 scm_status_term_sig, scm_status_stop_sig): Modified to work with
4284 Ultrix versions of WIFSTOPPED, etc., which assume that their
4285 arguments are lvalues (hmm).
4287 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
4289 * eval.c: Doc fixes.
4291 * throw.c: Doc fixes; rearranged.
4293 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
4295 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
4297 * acconfig.h: Added entry for PACKAGE.
4298 * scmconfig.h.in: Regenerated.
4300 Changes to work with automake-1.1n, which has better libtool support.
4301 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
4302 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
4304 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
4306 * Makefile.in: Rebuild.
4308 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
4310 * stime.c (scm_mktime): take an optional zone argument.
4311 (scm_localtime): check putenv return value.
4312 (scm_strftime, scm_strptime): moved from posix.c. move #include
4314 stime.h, posix.h: update prototypes.
4315 (bdtime2c, setzone, restorezone): new static procedures.
4316 (scm_mktime, scm_strftime): use them.
4317 (scm_strftime): don't call mktime before strftime. Use
4318 filltime for return value.
4319 (filltime): convert NULL zname to #f.
4320 (scm_strptime): return a count of characters consumed, not
4321 the remaining string.
4323 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4325 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

4328 Uncomment localtime and mktime.
4330 * configure.in: add AC_STRUCT_TIMEZONE.
4332 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
4334 * stime.c (scm_init_stime): don't define ticks/sec.
4335 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
4336 return value problem and is still portable.)
4338 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
4340 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
4341 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
4342 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
4343 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
4344 cpp_err_symbols.c): Corresponding changes.
4345 * Makefile.in: Regenerated.
4347 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
4349 * posix.c (scm_putenv): don't check HAVE_PUTENV.
4350 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
4351 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
4352 * putenv.c: new file, from sh-utils 1.12.
4354 * posix.c (scm_environ): use malloc in place of scm_must_malloc
4355 since allocation isn't for Scheme objects.
4356 (scm_putenv): copy strings before placing in the environment.
4358 * stime.c (scm_current_time): throw an error if time returns -1,
4359 instead of returning #f.
4360 (scm_get_internal_real_time, scm_get_internal_real_time): use
4361 scm_long2num for return value instead of SCM_MAKINUM.
4363 * stime.h: prototypes updated.
4365 * stime.c (scm_time_in_msec): apparently unused, deleted.
4367 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4369 * configure.in: check for gettimeofday.
4371 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
4372 which may be more usefully portable than a gettimeofday interface.
4374 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
4376 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
4378 * Makefile.in: Regenerated.
4380 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
4382 * stime.c (filltime): recovered static procedure.
4383 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
4386 * posix.h: add prototype for scm_close_pipe, remove prototypes for
4387 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
4389 * posix.c (scm_mknod): split the mode argument into type and perms
4390 arguments, like the extra fields returned by stat.
4392 * fports.c (scm_pipob): set the close, free and print procedures.
4393 (scm_close_pipe): new procedure.
4395 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
4396 define them in boot-9.scm
4398 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4400 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
4401 wan't defined. Don't include fd.h.
4403 * Previously fd.h was regenerated whenever configure was run,
4404 forcing a couple of files to be recompiled.
4406 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
4407 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
4408 Check for _fileno as well as _file.
4410 * ioext.c: don't fd.h.
4411 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
4414 * Change the stratigy for getting information about errno
4415 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
4416 generating lists of symbols during the build process, which will
4417 not always work, include comprehensive lists in the distribution.
4418 To help keep the lists up to date, the "check_signals" and
4419 "check_errnos" make targets can be used.
4421 * configure.in: don't check for a command to extract errno codes.
4422 * Makefile.am: update file lists, remove errnos.list and errnos.c
4423 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
4424 check_errnos targets.
4425 (CLEANFILES): remove errnos.c and errnos.list, add
4426 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
4427 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
4428 * errnos.default: deleted.
4429 * cpp_signal.c: new file.
4430 * cpp_errno.c: renamed from errnos_get.c.
4431 * cpp_err_symbols, cpp_sig_symbols: new files.
4432 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
4433 * error.c (scm_init_error): #include cpp_err_symbols instead of
4435 * posix.c (scm_init_posix): don't intern signal symbols. #include
4438 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
4440 * strop.c (scm_i_index): allow the lower bound to be equal to the
4441 length of the string, so a null string doesn't always give an error.
4443 * posix.h: new prototypes.
4444 * posix.c (scm_status_exit_val, scm_status_term_sig,
4445 scm_status_stop_sig): new functions, as in scsh. They break down
4446 process status values as returned by waitpid.
4448 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
4450 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
4451 configure doesn't know about it.
4453 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4455 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
4457 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
4458 which defines C variables with global linkage.
4460 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4462 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
4465 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
4467 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
4468 has time to check why this doesn't work well with continuations.
4470 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
4472 * Fix shell syntax error; some shells won't tolerate
4473 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
4475 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
4477 * posix.c (scm_uname): throw an error if uname fails instead
4480 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
4482 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
4485 * async.c (scm_ints_disabled): definition moved from error.c.
4487 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4489 * acconfig.h: Removed PACKAGE.
4491 * scmconfig.h.in: Regenerated.
4493 * snarf.h: g++ says it's non-portable not to specify the first
4494 argument in a varargs declaration. I introduced the first
4495 argument by using preprocessor conditionals.
4497 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
4499 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
4500 (scm_freopen): use RO string macros for filename and modes.
4501 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
4503 * posix.c (scm_getgrgid): simplify conversion of name to C string.
4504 (scm_mknod): use RO string macros for path.
4506 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
4507 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
4509 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4510 use SCM_ROSTRINGP and SCM_ROCHARS.
4512 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4514 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
4517 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
4518 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
4519 support for byte vectors.
4521 * print.c (scm_iprin1): Limit number of vector elements printed
4522 according to pstate->length.
4524 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
4526 * backtrace.c (scm_display_error_message): don't segv if message
4529 * error.h: prototype for scm_error_scm.
4531 * error.c (scm_error_scm): new procedure, reimplements scm-error
4532 in C and uses scm_error.
4534 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
4536 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
4537 pointer to the Scheme variable read-hash-procedures and intern it
4538 in scm_init_read. Modify scm_read_hash_extend and
4539 scm_get_hash_procedure to use the pointer.
4541 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
4543 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
4544 (SCM_KEYWORD_STYLE): defined.
4546 * read.c (scm_read_opts): add a keywords option. This isn't a
4547 boolean option, in case someone wants to add support for DSSSL
4549 Setup scm_keyword_prefix symbol.
4550 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
4552 I've left keyword support disabled by default, since it doesn't
4553 seem to break the module system and it gives R4RS standard behaviour.
4554 It can be reactivated with (read-set! keywords 'prefix).
4556 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4558 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
4559 before constructing arbiter.
4561 * eval.c (scm_m_define): Bugfix: Check that the object is a
4562 closure before setting the procedure property!
4564 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
4566 * ports.c: Removed `ungetc-char-ready?'.
4568 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
4570 * read.c (scm_init_read): intitialise scm_read_hash_procedures
4571 (idea from Mikael: make it a pair so scm_permanent object only
4573 (scm_read_hash_extend): don't call scm_permanent_object.
4574 (ideas from Mikael): if chr is already in the list, replace its
4575 procedure instead of appending it again. If proc is #f, remove
4577 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
4579 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
4581 * gdbint.c (gdb_read): update scm_lreadr usage.
4583 * load.h: update prototypes.
4585 * load.c (scm_primitive_load, scm_read_and_eval_x,
4586 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
4588 * read.h: add prototype for scm_read_hash_extend. Change args for
4591 * read.c (scm_read_hash_procedures): new variable.
4592 (scm_read_hash_extend): new procedure.
4593 (scm_get_hash_procedure): new procedure.
4594 (scm_lreadr): use scm_get_hash_procedure instead of an argument
4595 for extended # processing.
4596 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
4597 scm_read_token): remove case_i, sharp arguments. Change callers.
4599 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
4601 * read.h (SCM_N_READ_OPTIONS): increase to 3.
4602 (SCM_CASE_INSENSITIVE_P): define.
4604 * read.c: add case-insensitive option to scm_read_opts.
4605 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
4606 to determine whether to convert symbol case.
4607 (default_case_i): definition removed.
4608 * read.c (scm_read_token): if case_i, downcase ic before doing
4611 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4613 * configure.in: Added configuration option `guile-debug'.
4614 Configure with --enable-guile-debug if you want a bunch of extra
4615 functions used for debugging when developing Guile.
4617 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
4619 * procs.c (make-cclo): New undocumented debugging procedure: Make
4620 compiled closure with internal procedure PROC and length LENGTH.
4621 Only compiled if GUILE_DEBUG is defined.
4623 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
4625 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
4627 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
4629 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
4630 with 3 or more args internally to the evaluator.
4632 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4634 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
4635 with 3 or more args internally to the evaluator. This is mainly
4636 because we don't want to pass entry and exit points of the
4637 debug support twice, but it also seems to increase the speed of
4638 the evaluator for such calls (e. g. (+ 1 2 3)).
4640 * backtrace.c (scm_display_application): New procedure:
4641 display-application; Set fancy printing parameters individually
4642 for different types of display (backtrace, error, application).
4643 (These should of course be customizable!)
4645 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
4646 clear the CHECK-flags.
4648 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4650 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
4652 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4654 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
4655 from pairs with a GLOC in the car.
4657 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
4658 otherwise `symbol-hash' will behave badly.
4659 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
4660 we get segmentation fault!
4662 * symbols.c: Added #include "weaks.h". New functions:
4663 `builtin-bindings' and `builtin-weak-bindings'. (These will be
4664 moved to an extraneous library when we split libguile.)
4666 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4668 * filesys.c (scm_stat): stat now takes fport arguments too as
4669 documented in the manual.
4671 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4673 * debug.c (scm_single_step): Bugfix: Call continuation with
4674 scm_call_continuation instead of throwing to it.
4676 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4678 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
4679 argument wasn't declared to be optional.
4681 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4683 * stime.c (scm_init_stime): Add feature "current-time".
4685 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
4687 * throw.h: prototype for scm_exit_status.
4688 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
4689 args to derive an exit status. Allows (quit) to work from a
4691 (scm_exit_status): new function.
4694 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4696 * eval.c (scm_deval): Removed some old code.
4697 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
4699 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
4702 * symbols.c (msymbolize): Bugfix: Must initialize property list to
4705 * procs.c: Introduce the existent C function scm_thunk_p at the
4706 Scheme level as well.
4708 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4710 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
4711 used from C to easily lookup the value of a symbol in the current
4714 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4716 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
4717 scm_init_unif in this file. This will also fix a previous problem
4720 * configure.in: Added AM_MAINTAINER_MODE
4722 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4724 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
4727 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
4729 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
4730 source files that are not always included in libguile but should
4731 have their dependencies calculated by automake. This variable is
4732 recognized by automake, no further magic is needed.
4733 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
4734 to deal exclusively with *.lo files, as it seems. The *.o files
4735 are built automatically when the corresponding *.lo file gets
4738 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
4740 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
4743 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
4745 * unif.c (scm_array_set_x): minor change to argument error checking.
4747 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
4749 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
4750 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
4751 They should only be included in the library at configure.in's
4753 (libguile_la_LDADD): Include the appropriate .lo files here.
4754 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
4755 so we know when to build them (and their .lo bretheren).
4756 * configure.in (LIBLOBJS): New substituted variable. We let
4757 configure decide which .o files to include in LIBOBJS, and then
4758 put the corresponding list of .lo files in LIBLOBJS. The latter
4759 is what we pass to libtool.
4760 * Makefile.in, configure: regenerated.
4762 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
4764 * symbols.c (scm_sysintern0): New function. Contains the core of
4765 old scm_sysintern but doesn't take a second value argument.
4766 (scm_sysintern): Now uses scm_sysintern0.
4767 (scm_sysintern_no_module_lookup): Renamed to
4768 scm_sysintern0_no_module_lookup and doesn't take a second value
4769 argument any longer.
4771 * symbols.h (scm_sysintern0: Added declaration.
4773 * options.c (scm_init_opts): Use scm_sysintern0 instead of
4774 scm_sysintern when interning option keys. Otherwise we risk
4775 destroying the values of already interned variables.
4777 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
4778 scheme-level boolean (use SCM_NFALSEP).
4780 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
4782 (scm_backtrace): New function. (C version of old function from
4783 boot-9.scm) Motivation: Make it possible to display backtraces
4784 without depending on boot-9.scm. (I'm uncertain if this
4785 motivation is good enough...)
4787 * root.h (scm_root_state): Add member the_last_stack_var.
4788 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
4790 * root.c (mark_root): Mark scm_the_last_stack_var.
4792 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
4795 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
4797 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
4798 1. mark_lazy_catch didn't mark the smob.
4799 2. Both functions above have standard variants:
4800 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
4801 free_lazy_catch --> scm_free0.
4803 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
4805 * throw.c (scm_internal_lazy_catch): New function.
4806 (scm_lazy_catch): Rewritten to use it.
4807 (scm_ithrow): Handle the new lazy catch representation.
4808 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
4809 that doesn't have a jmpbuf is a lazy catch clause.
4810 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
4811 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
4812 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
4814 (scm_init_throw): Register the new lazy-catch smob type.
4815 * throw.h (scm_internal_lazy_catch): decl for new function.
4817 * throw.c (scm_internal_catch): Doc fixes.
4819 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
4820 configure.in. Including this might cause problems if applications
4821 that link against libguile include their own copies of alloca, but
4822 if they're using autoconf, they should be adding libguile to LIBS
4823 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
4824 the copy in libguile, and things will be okay. (I think.)
4826 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4828 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
4830 strop.h: move prototypes too.
4832 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
4834 * posix.c (scm_init_posix): don't intern EINTR since it's now done
4837 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
4838 etc. I deleted them from filesys.c long ago, but didn't
4839 notice they were here too (although ineffective since
4840 sys/stat.h wasn't included).
4842 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
4844 * eval.c: Don't define alloca in GCC case. gcc will automatically
4845 use __builtin_alloca if appropriate.
4847 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4849 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
4850 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
4851 that values of automatic variables are preserved. See comments
4852 for safe_setjmp for details.
4854 Change from Thomas Morgan:
4855 * variable.c: Include eq.h.
4856 (var_equal): New function.
4857 (variable_smob): Use var_equal as the discriminator for variables.
4859 * throw.c (s_throw): Remove extraneous declaration.
4861 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
4862 * eval.c: Add necessary CPP cruft to support that.
4863 * configure, Makefile.in, scmconfig.h.in: regenerated.
4865 Change from Thomas Morgan:
4866 * procprop.c (scm_procedure_properties): Convert the Scheme
4867 boolean returned by scm_procedure_p into a C boolean before using
4868 it as a condition for SCM_ASSERT.
4869 (scm_procedure_property): Likewise.
4871 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
4872 indications of Unixness.
4875 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
4877 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
4879 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
4881 * read.c (scm_lreadr): use scm_misc_error to improve one of the
4882 "unknown # object" error messages.
4884 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
4885 (scm_i_index) and declare it static. Add a 'direction' argument
4886 to indicate what way the search should go.
4887 (scm_i_index): throw out-of-range error instead of wrong-type-arg
4889 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
4890 strop.h: remove scm_i_index, scm_i_rindex prototypes.
4892 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4894 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
4896 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
4897 to avoid clash with various scsh forks.
4899 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
4901 The following two changes (ramap.c, throw.c) are motivated by the
4902 apparent unportability of forward declarations of static arrays of
4903 the form `static foo bar[];'.
4905 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
4906 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
4908 * throw.c (scm_throw): Moved above scm_ithrow.
4910 * options.h: Removed the extern declarations of scm_yes_sym and
4911 scm_no_sym since these are static.
4913 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4915 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
4917 * Makefile.am: remove AWK=@AWK@.
4918 Add a rule for generating errnos.list.
4919 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
4921 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
4922 don't extract errnos, just set a variable (avoids the
4923 need to recompile error.c just because configure is run.)
4925 * unif.h: update prototypes.
4926 * unif.c (scm_uniform_array_read,write): change the offset and
4927 length arguments to start and end, for consistency.
4929 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
4931 * ioext.h: update prototypes.
4932 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
4933 scm_read_line_x, it's a more general procedure using an
4934 interface from scsh. read-line and read-line! are now defined
4936 Note that the new read-line trims the terminator
4937 by default, previously it was appended to the returned string. An
4938 optional argument specifies how to process the terminator (scsh
4939 compatible). For the old behaviour: (read-line port 'concat).
4940 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
4941 returns a pair, but is converted to multiple values if the scsh
4944 socket.h: update prototypes.
4945 * socket.c (scm_recvfrom): for consistency with other procedures,
4946 take start and end as separate optional arguments.
4947 (scm_recv, scm_recvfrom): don't allow the second argument
4948 to be a size, only a buffer. Change the scheme names to
4949 recv! and recvfrom!. Don't return the buffer.
4951 * ioext.h, posix.h: move prototypes too.
4952 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
4953 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
4954 "read.h" and "unif.h".
4955 * ioext.c: include "chars.h"
4957 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
4959 * dynl.c: The dynamic linking and module registration functions
4960 are now defined even when dynamic linking is not available for the
4961 host system. Some of their functionality can be done without
4962 dynamic linking; when it's really needed, they throw errors.
4964 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
4966 * configure.in: Only define DYNAMIC_LINKING when one of the system
4967 dependent functions is detected.
4968 * dynl.c (scm_dynamic_func): New function to get the address of a
4969 function in a dynamic object.
4970 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
4971 produced by scm_dynamic_func as the thing to call.
4973 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
4975 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
4976 (scm_register_module_xxx, scm_registered_modules,
4977 scm_clear_registered_modules): New functions.
4979 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
4981 * symbols.c (scm_sysintern): Renamed to
4982 scm_sysintern_no_module_lookup.
4983 (scm_sysintern): New function to take the place of the old
4984 scm_sysintern. It uses the current toplevel lookup closure to give
4985 the symbol its value. This is a temporary hack to put packages
4986 like gtcltk into their own module.
4987 (scm_can_use_top_level_lookup_closure_var): New variable to tell
4988 us whether `scm_top_level_lookup_closure_var' has been initialized
4990 * eval.c (scm_init_eval): Set it.
4992 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
4994 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
4995 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
4997 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
4999 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5000 scm_sys_dup): deleted: FD capability will be added to other
5002 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5003 scm_fd_free, fd_smob, scm_intern_fd.
5004 (scm_open): renamed from scm_sys_open. Return a port instead of
5005 an FD object. Make the mode argument optional.
5006 (scm_sys_create): deleted, it's just a special case of open.
5007 (scm_init_filesys): move interning of constants O_CREAT etc.,
5008 here (were previously using SCM_CONST_LONG macro).
5009 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5011 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5012 include "fports.h" and <stdio.h>
5013 (scm_stat, scm_select): don't support FD objects.
5015 * error.h: adjust scm_syserror_msg prototype.
5016 * error.c (scm_syserror_msg): take an extra argument for errno.
5017 Using the global value didn't always work, since it could be
5018 reset by procedure calls in the message or args arguments.
5020 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5021 I don't understand why the check was there (and what about the
5024 * strop.c (scm_string_copy): allow shared substrings to be copied.
5026 * unif.h: corresponding change to prototypes.
5027 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5028 recognize two new optional arguments: offset and length. Allow
5029 the port argument to be an integer (file descriptor, for scsh).
5030 Include <unistd.h> for "read" prototype.
5032 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5034 * socket.c: don't include filesys.h.
5036 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5038 * Makefile.am: add AWK=@AWK@ (?)
5040 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5042 Add a rule to generate errnos.c from errnos.
5043 * error.c (scm_init_error): include errnos.c.
5044 * errnos_cnvt.awk: new file, converts the list of errno codes to
5046 * errnos_get.c: new file.
5047 * errnos.default: new file, contains errnos to try if they can't
5048 be extracted from errno.h.
5049 * configure.in: if using GCC, try and extract errno codes from
5053 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5055 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5056 * Makefile.am: Made libguile into a libtool library.
5057 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5058 Set libtool_libs to indicate that libguile is a libtool library.
5059 See guile/ChangeLog for details.
5060 * .cvsignore: ignore "*.lo", the libtool library objects.
5062 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5064 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5065 use htons in getservbyport argument.
5067 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5069 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5070 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5073 * objprop.c (scm_object_property): No need to take the CDR of the
5074 value returned by scm_object_properties, since Aug 20 change.
5076 * configure.in: When checking for struct linger, #include
5077 <sys/types.h> as well as <sys/socket.h>. I've never known
5078 <sys/types.h> to cause any portability problems, and Solaris's
5079 <sys/socket.h> needs it.
5080 * configure: Rebuilt.
5082 I think the Sun compiler has chosen a perverse way to interpret
5083 ANSI declarations combined with K&R definitions. We'll
5084 appease it a little bit. But when it invades France, we fight.
5085 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5086 * print.h (scm_iprlist): Here too.
5087 * numbers.c (scm_divbigdig): Change definition to match
5088 declaration in numbers.h.
5089 * unif.c (scm_makflo): Change definition to match declaration in
5092 * init.c (scm_boot_guile): Don't return the value of
5093 scm_boot_guile_1. This function doesn't return a value;
5094 scm_boot_guile_1 doesn't return a value (or return at all).
5096 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5099 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5100 compile. I have a feeling this function is a bad idea anyway ---
5101 one should always test for features, not systems.
5103 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5104 semicolons. Only pure luck kept this from being noticed earlier.
5106 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5108 * socket.c (scm_recvfrom): Added missing semicolon.
5110 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5112 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5113 the buffer and start and end positions for scsh networking
5116 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5118 * configure.in: Revert previous change to this file; the problem
5119 is due to transient automake weirdness.
5120 * configure: Rebuilt.
5122 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5123 PLUGIN/guile.libs. configure generates the latter from the former.
5124 * Makefile.in: Rebuilt.
5126 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5127 need this if we install scripts, like guile-snarf.
5128 * configure: Rebuilt.
5130 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5132 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5134 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5136 * socket.c (scm_addr_vector): fix faulty scm_listify.
5138 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5140 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5141 style block comment is no longer considered an error.
5143 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5145 * PLUGIN/guile.libs.in: New file.
5146 * PLUGIN/guile.libs: Removed from repository.
5147 * configure.in: Create PLUGIN/guile.libs from
5148 PLUGIN/guile.libs.in. This is for including additonal libraries
5149 needed for dynamic linking.
5150 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5151 instead of PLUGIN/guile.libs.
5153 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5155 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5157 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5158 occurrences of the given element from the list, not just the
5159 first. This is how the Emacs Lisp functions behave, how the
5160 analogous Common Lisp functions behave, and (I believe) how the
5161 older Maclisp functions worked. I realize that this change may
5162 break code, but it seemed better to break it before the Guile
5165 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5166 Their prototypes were already present in gc.h, but they weren't
5168 (scm_init_storage): Initialize scm_protects.
5169 * root.c (scm_protects): New element of scm_sys_protects.
5171 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5173 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5175 * libguile.h: Added #include "libguile/net_db.h".
5177 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5178 30 change. That file is only meant for communication between the
5179 configuration process and load.c. If code linked against libguile
5180 wants to get at the paths mentioned in libpath.h, it can call
5181 functions declared in load.h.
5183 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5185 * libguile.h: Removed #include "libguile/fdsocket.h"
5187 * net_db.c: Added #include <sys/socket.h>.
5189 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
5191 * filesys.c (scm_input_waiting_p): use select in preference to
5192 FIONREAD, since the latter doesn't detect EOF.
5193 Throw error if neither select nor FIONREAD available.
5195 * socket.c (scm_connect): take a port, not a fd object.
5196 (scm_fill_sockaddr): throw an error if fam is not recognised.
5197 (scm_bind): use scm_fill_sockaddr.
5198 (scm_listen): take a port, not a fd object.
5199 (scm_accept): take and return a port. return #f in the car if
5200 address can't be got
5201 (scm_sock_fd_to_port): new procedure.
5202 (scm_socket): use scm_sock_fd_to_port.
5203 (scm_addr_vector): throw error if unrecognised address type.
5204 take an extra argument with the calling procedure name.
5205 (scm_getsockname): take a port. return #f if address can't be got.
5206 (scm_getpeername): take a port. return #f if address can't be got.
5207 (scm_recvfrom): take a port. return #f for address component if can't
5209 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
5210 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
5212 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
5214 * throw.c (scm_internal_catch): Make body funcs and handler funcs
5215 use separate data pointers, to allow them to be designed
5216 independently and reused.
5217 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
5218 Renamed from catch_body, catch_handler, and uncaught_throw; made
5220 (struct scm_catch_body_data): Renamed from catch_body_data; moved
5222 (scm_catch): Use the above.
5223 (scm_throw): Don't bother printing a message for an uncaught
5224 throw; we establish a default handler in init.
5225 * throw.h (scm_internal_catch): Prototype updated.
5226 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
5228 (struct scm_body_thunk_data): New structure, used as data
5229 argument to scm_body_thunk.
5230 * init.c (struct main_func_closure): New structure, packaging up
5231 the data to pass to the user's main function.
5232 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
5233 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
5234 scm_internal_catch to establish a catch-all handler, using
5235 scm_handle_by_message. This replaces the special-case code in
5237 (invoke_main_func): Body function for scm_internal_catch; invoke
5238 the user's main function, using the main_func_closure pointer to
5239 decide what to pass it.
5240 * root.c (struct cwdr_body_data): Remove handler_proc member.
5241 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
5242 (cwdr_handler): Removed.
5244 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5246 * socket.h (SCM_P): update bind prototype.
5247 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
5248 include "feature.h".
5249 (scm_socket): return a port, not a file descriptor object.
5250 include "fports.h" and <unistd.h>
5251 (scm_bind): take a port, not a file descriptor object.
5252 take an extra argument for address args.
5254 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
5255 INADDR_NONE, INADDR_LOOPBACK.
5257 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5259 * init.c: include net_db.h and not fdsocket.h.
5260 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
5262 * Makefile.am: corresponding changes.
5263 * socket.h: renamed from fdsocket.h, fix names.
5264 * net_db.h: renamed from socket.h, fix names.
5265 * socket.c: renamed from fdsocket.c.
5266 remove _sys from procedure names.
5267 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
5268 add "socket" to features list.
5269 * net_db.c: renamed from socket.c.
5270 remove _sys from procedure names.
5271 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
5272 add "net-db" to features list.
5273 include "net_db.h". don't include <sys/socket.h> or
5276 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5278 * tags.h (scm_tags): Removed comma at end of last enumerator.
5280 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
5282 Don't use GCC extensions to allocate space for debugging frames.
5283 (Here he goes again! Why do we put up with this?!)
5284 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
5285 an scm_debug_info structure, not an in-line array of them. Add
5286 'info' member, to say how many vect elements we've used, for eval
5288 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
5289 a new variable debug_info_end to mark the end of vect, instead of
5290 the address of the 'info' pointer itself.
5291 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
5292 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
5293 (SCM_APPLY): Explicitly allocate space for debug.vect.
5294 * debug.c (scm_m_start_stack): Same, for vframe.vect.
5295 * stacks.c: Adjusted for new debug frame structure.
5296 (RELOC_INFO, RELOC_FRAME): New macros.
5297 (stack_depth, read_frames): Use them, and new scm_debug_frame
5298 element 'info', instead of magically knowing that eval frames have
5299 an info pointer sitting after vect.
5300 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
5302 (scm_init_stacks): Formatting tweaks.
5304 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
5306 Give GCC more control flow information, so it can be sure that
5307 variables aren't used uninitialized.
5308 * error.h (scm_error, scm_syserror, scm_syserror_msg,
5309 scm_sysmissing, scm_num_overflow, scm_out_of_range,
5310 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
5311 scm_misc_error): Tell GCC that these functions never return.
5312 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
5313 out the field type, call abort if SCM_ASSERT returns, to placate
5315 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
5316 scm_wta ever returns. We can't handle this case anyway, and this
5317 gives the optimizer more information.
5318 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
5319 scm_wta ever returns.
5321 In some cases, the code is fine, but GCC isn't smart enough to
5322 figure that out; this usually happens when one variable is only
5323 initialized and used when a particular condition holds true, and
5324 we know that condition will never change within a given invocation
5325 of the function. In this case, we simply initialize the variables
5326 to placate the compiler, hopefully to a value which will cause a
5327 crash if it is ever actually used.
5328 * print.c (scm_iprin1): Initialize mw_pos.
5329 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
5330 * throw.c (scm_ithrow): Initialize dynpair.
5331 * unif.c (scm_uniform_vector_ref): Initialize cra.
5332 * struct.c (init_struct): Initialize prot.
5333 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
5335 * strports.c (scm_eval_0str): Don't return uninitialized garbage
5336 if EXPR contains no expressions.
5338 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5340 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
5341 cause an infinite loop (???). So much for the algebraic
5342 equivalency of variable-sized arrays and alloca...
5344 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
5346 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
5347 a SCM boolean, not a C boolean.
5349 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
5351 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
5352 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
5353 rules for raising scm_mtrigger. Previously, unfortunate but not
5354 unlikely circumstances could result in almost constant invokation
5355 of the gc. Now, this situations should be less likely, but they
5356 are not prevented completely.
5358 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
5360 * numbers.c (scm_fuck): Procedure removed; looks like old test
5362 * numbers.h: Prototype removed.
5364 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
5366 * debug.h (scm_debug_frame): Change `vect' member from an in-line
5367 array to a pointer, to match my Nov 21 change in eval.c.
5369 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5371 * libguile.h: Added #include "libguile/backtrace.h", #include
5372 "libguile/stacks.h".
5374 * strings.c (scm_string scm_make_string scm_string_ref
5375 scm_string_set_x scm_string_equal_p scm_string_append):
5376 Bugfix according to scm patch from Aubrey Jaffer:
5377 Corrected long-standing
5378 (not (eqv? (integer->char 128)
5379 (string-ref (make-string 1 (integer->char 128)) 0)))
5380 bug found by John Kozak <jk@noontide.demon.co.uk>.
5382 * strports.c, strports.h: Make scm_eval_0str return the value of
5383 the last expression evaluated (previously, it returned void).
5385 * strports.c, strports.h: New function: scm_read_0str. Does what
5388 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5390 * simpos.c (scm_getenv): return #f if string can't be found in the
5391 environment instead of throwing an exception, for compatibility
5392 with numerous other systems.
5394 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
5396 * Makefile.am (.c.x): Use guile-snarf.
5397 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
5399 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
5401 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
5403 * backtrace.c (scm_display_error_message): Made non-static, and
5404 renamed from display_error_message.
5405 * backtrace.h (scm_display_error_message): Added extern decl.
5406 * throw.c (uncaught_throw): Use it to display the error message.
5408 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
5410 * inet_aton.c: Use #if 0, not #ifdef 0.
5412 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
5414 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
5415 to convert the returned value.
5416 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
5417 the offset argument.
5419 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
5421 Add new interface to catch/throw, usable from C as well as
5423 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
5424 (scm_internal_catch): New function, replaces...
5425 (scm_catch_apply): Deleted.
5426 * throw.c (scm_catch_apply): Deleted; replaced with a more general
5427 mechanism which is a bit more code, but can be used nicely from C
5428 and implement the Scheme semantics as well.
5429 (scm_internal_catch): This is the replacement; it's named after
5430 the analogous function in Emacs.
5431 (scm_catch): Reimplemented in terms of the above.
5432 (struct catch_body_data, catch_body, catch_handler): New
5433 functions, used by scm_catch.
5434 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
5435 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
5436 support for new cwdr.
5438 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
5441 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
5443 * acconfig.h: Added DYNAMIC_LINKING symbol.
5444 * configure.in: Add option and checks for dynamic linking.
5445 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
5446 dynl.h: New files for dynamic linking support.
5447 * Makefile.am (libguile_a_SOURCES):
5449 (modinclude_HEADERS): Added "dynl.h".
5450 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
5452 * init.c (scm_boot_guile_1): Call
5453 scm_init_dynamic_linking to initialize dynamic linking support.
5455 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
5457 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
5458 (as we Schemers say). It needs to be global, so that I can tweak
5459 it for the proper operation of unexec.
5460 (scm_boot_guile_1_live): New variable, see above.
5462 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
5464 * guile-snarf.sh: Removed.
5465 * PLUGIN/guile.libs: Added dependency for -lm.
5466 * acinclude.m4: Renamed from aclocal.m4.
5467 * PLUGIN/greet: Removed.
5468 * Makefile.am, aclocal.m4: New files.
5469 * configure.in: Updated for Automake.
5471 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
5473 * eval.c (scm_definedp): Use top_level_lookup_closure_var
5474 and not top_level_lookup_thunk_var.
5476 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
5478 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
5480 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
5482 * eval.c (scm_definedp): Incompatibly changed to be a builtin
5483 Scheme function, instead of syntax. Single argument is now a
5486 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5488 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
5489 scm_ra_divide): Properly terminate statements passed as arguments
5490 to IVDEP macros. (Thanks to Bernard Urban.)
5492 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
5493 with non-constant sizes. (Thanks to Bernard Urban.)
5495 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
5497 It's an "eval closure", not an "eval thunk." A thunk is a
5498 function of no arguments.
5499 * root.h (struct scm_root_state): Renamed
5500 top_level_lookup_closure_var from top_level_lookup_thunk_var.
5501 (scm_top_level_lookup_closure_var): Renamed from
5502 scm_top_level_lookup_thunk_var.
5503 * root.c (mark_root): Uses changed.
5504 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
5505 * init.c (scm_start_stack): Uses changed.
5506 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
5507 Change scheme-visible name to *top-level-lookup-closure* from
5508 *top-level-lookup-thunk*.
5510 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
5512 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
5513 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
5515 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
5517 * gc.c (struct scm_heap_seg_data): Doc fixes.
5519 * gc.c (scm_gc_sweep): Empty all segments' freelists before
5520 sweeping. Then, prepend each segment's free cells to its
5521 freelist, rather than wiping out the old value. (Thanks to Marius
5524 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
5525 scm_check_freelist, scm_debug_newcell): New functions and
5526 variables, for debugging freelist problems.
5527 * pairs.h (SCM_NEWCELL): New debugging version added.
5528 * gc.h (scm_debug_newcell): Added extern declaration, used by
5529 debugging version of SCM_NEWCELL.
5531 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5533 On some systems <libc.h> conflicts with <unistd.h>, and should not
5534 be #included at all.
5535 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
5536 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
5537 * configure.in: Call it.
5538 * posix.c, filesys.c: Use its results to decide whether or not to
5540 * configure, scmconfig.h.in: Rebuilt with autoconf and
5543 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5545 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
5546 pointer to the stdio stream before calling scm_setbuf0, so the
5547 latter will be able to retrieve it. I'm surprised this didn't
5548 segfault earlier. (Thanks to Christopher Lee.)
5550 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5552 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
5555 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5557 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
5558 number of stack narrowing specifier pairs. The first specifier in
5559 a pair controls inner border, the second the outer border. A
5560 number means cut that number of frames, a procedure object means
5561 cut until that object is found in operator position in a frame.
5563 * root.c (cwdr): Bugfix.
5565 * read.c: Recording of positions disabled by default.
5567 * procs.c (scm_closure_p): New function.
5569 * posix.c (scm_tmpnam): New function.
5571 * load.c: Added #include "throw.h".
5572 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
5575 * load.c, load.h (scm_read_and_eval_x): New function.
5577 * eval.c: Renamed debug option "deval" to "debug".
5579 (scm_eval_x): `eval!' is no longer accessible from the scheme
5580 level. Motivation: We can't allow operations which introduce
5581 glocs into the scheme level. Guile's type system can't handle
5582 these as data. Use `eval' or `read-and-eval!' as replacement.
5584 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
5585 SCM_CONSP since this is a macro!; Set vframe.prev to
5586 scm_last_debug_frame instead of 0. In this way we can look
5587 "above" the virtual start stack frame if we wish.
5588 (scm_debug_hang): New function: Useful for debugging Guile in
5589 certain tricky situations. Will probably be removed later...
5591 * debug.h: Changed semantics of debug option "backtrace". This
5592 option now only indicates whether we want automatic backtrace at
5595 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5597 * ports.c: #include "filesys.h"
5598 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
5600 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
5601 Motivation: This is system specific code which is related to file
5602 I/O. It also may use select. Added code by Gary Houston to
5603 detect presence of character in stdio buffers.
5605 * libguile.h: #include "libguile/libpath.h"
5607 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
5608 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
5609 SCM_SITE_DIR; Install libpath.h among the other include files.
5611 * load.c, load.h (scm_sys_package_data_dir): New function.
5613 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5615 * stacks.h: Bugfix: Don't use tail-array length field as stack
5616 length field! This screwed GC.
5618 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5620 * _scm.h: Added #ifndef around definition of macros min and max.
5622 * __scm.h: Added hooks for threads to plugin to in ints protection
5623 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
5624 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
5625 the main code in these macros duplicated and spread over multiple
5626 files. Renamed SCM_THREADS_SWITCHING_CODE ->
5627 SCM_THREAD_SWITCHING_CODE.
5629 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
5631 * snarf.h: New file.
5632 * guile-snarf.sh: New file.
5633 * Makefile.in (inner_h_files): Added snarf.h
5634 (ancillary, install, uninstall, distclean): Added actions for
5636 (.c.x): Use guile-snarf.
5637 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
5638 (gen_c_files): Note that these depend on guile-snarf.
5639 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
5640 now in "snarf.h". Added #include "snarf.h" to get them.
5641 * libguile.h: Added #include "snarf.h".
5642 (Patches applied and tweaked by Jim Blandy.)
5644 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
5646 * socket.c: Use K&R style declaration for 'close'; the GNU coding
5647 standards suggest against providing prototypes for system
5648 functions. Thanks to Greg Troxel.
5650 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5652 * strports.c (scm_eval_0str): New function.
5653 #include "read.h", to get prototype for scm_read.
5654 * Makefile.in (strports.o): Update dependencies.
5655 * strports.h: New prototype.
5657 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
5658 scheme name from "int?" to "integer?". It seems to do the job.
5659 * numbers.h: Rename prototype too.
5660 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
5663 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
5664 scm_num_eq_p): Rename these according to R4RS conventions: call
5665 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
5666 to making libguile R4RS compliant without ice-9...
5668 * load.c (scm_sys_search_load_path): Search for files under all
5669 extensions listed in the %load-extensions variable. If FILENAME
5670 is absolute, return it unchanged, without searching the load path.
5671 (scm_loc_load_extensions): New variable, pointing to
5672 %load-extensions' value cell.
5673 (scm_init_load): Initialize it, and the value it points to.
5674 (scm_primitive_load_path): Improve error reporting.
5676 * load.c (scm_loc_load_hook): New variable, pointing to value cell
5677 of new Scheme variable %load-hook.
5678 (scm_primitive_load): Apply %load-hook to filename.
5680 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
5682 * configure.in: add tests for figuring out whether buffered data
5683 is available in a FILE structure, which is needed by char-ready.
5685 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
5688 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
5689 exceptions using misc_error instead of syserror. It seems a bit
5690 odd to throw an exception if a string can't be found in the
5691 environment, but it's consistent with open-file, stat etc.
5692 (simpos.h): remove sys_ from getenv.
5694 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
5695 occurs, throw an error instead of returning errno. Return value
5697 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
5699 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
5701 * filesys.c (scm_stat2scm): derive file type and permissions from
5702 the stat mode and append them to the returned vector.
5703 There isn't much overhead in doing this and it avoids the need to
5704 work with S_IRUSR et al. in Scheme.
5705 Define symbols scm_sym_regular etc.
5706 (scm_init_filesys): don't intern S_IRUSR etc.
5708 * load.c: change s_try_load and s_try_load_path to s_primitive_load
5709 and s_primitive_load_path.
5711 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
5713 * error.h: don't declare error symbols. prototype for scm_misc_error.
5715 * stackchk.c (scm_stack_overflow_key): defined here instead of in
5718 * error.c: use SCM_SYMBOL to set up error keys.
5719 scm_misc_error: new procedure.
5721 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5723 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
5724 between `#!' and `!#' is ignored.
5725 (skip_scsh_block_comment): New function.
5727 * feature.c (scm_set_program_arguments): New argument, FIRST.
5728 * feature.h: Update prototype.
5729 * init.c (scm_boot_guile_1): Pass new argument to
5730 scm_set_program_arguments.
5732 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
5734 * init.c (scm_start_stack): Don't initialize scm_progargs here.
5735 (scm_boot_guile): Call scm_set_program_arguments here, later than
5736 the old initialization.
5738 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
5739 initialization procedure.
5740 - Delete in, out, err arguments; there are other perfectly good
5741 ways to override these when desired.
5742 - Delete result argument; this function shouldn't ever return.
5743 - Rename init_func argument to main_func, for less confusion.
5744 - Delete boot_cmd argument; main_func is more general.
5745 -Add 'closure' argument, to help people pass data to main_func
5746 without resorting to global variables.
5747 - Abort if reentered; don't bother returning an error code.
5748 - Call scm_init_standard_ports to set up the default/current
5749 standard ports; no need to pass them to scm_start_stack.
5750 - Remove code to evaluate the boot_cmd, and start the repl; let
5751 the user do something like that in main_func if they want.
5752 - Remove code to package up a return value; main_func can do any
5754 - Call exit (0), instead of returning.
5755 (scm_start_stack): Don't initialize the I/O ports here; that's
5756 weird. Delete in, out, err arguments. Move guts to
5757 scm_init_standard_ports, scm_stdio_to_port.
5758 (scm_init_standard_ports): New function, to set up current and
5759 default standard ports.
5760 (scm_start_stack, scm_restart_stack): Make these static.
5761 * init.h (scm_boot_guile): Adjust declaration.
5762 (scm_start_stack, scm_restart_stack): Remove externally
5763 visible declarations for these.
5764 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
5766 * fports.c (scm_stdio_to_port): New function. Its guts used to be
5767 written out several times in scm_start_stack.
5768 * fports.h: New declaration for the above.
5770 * feature.c (scm_set_program_arguments): New function.
5771 * feature.h: New declaration for the above.
5773 * ports.c: Formatting tweak.
5775 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
5777 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
5778 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
5779 for obtaining the address of a car or cdr field. Motivation:
5780 &SCM_CXR make assumptions about the internal structure of the
5783 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
5784 Motivation: see SCM_CXRLOC.
5786 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
5787 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
5788 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
5789 Motivation: Safer use. Some other macros are defined in terms of
5790 these operations. If these are defined using the SCM_SETCXR
5791 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
5792 to inefficiency and an <e1> with side-effects could potentially
5793 break. Also, these particular operations are heavily utilized in
5794 the garbage collector. In unoptimized code there will be a
5797 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
5798 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
5799 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
5800 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
5801 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
5802 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
5803 vports.c: Cleaned up use of pairs: Don't make any special
5804 assumptions about the internal structure of selectors and
5805 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
5806 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
5807 (Among other things, this change makes it easier to build Guile
5808 with certain compilers which have problems with casted lvalues.)
5810 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5812 * stacks.c: Improve selection of relevant stack frames when making
5813 a stack object. Introduce one level of indirection in the stack
5814 object to make it possible to "narrow" to a certain region of the
5815 stack. This facilitates making use of more clever algorithms (not
5816 implemented) for selecting relevant frames and gives a cleaner
5817 design since selection of frames can be done independently of
5818 extraction of frames from the real stack.
5819 (scm_stack_id): Also take #t as argument which means look at
5822 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
5823 Turn n_tail into an integer directly representing current number
5824 of frames in stack. Add field tail.
5826 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
5828 * debug.c (scm_make_memoized): Made it available at scheme level.
5829 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
5830 SCM_NIMP before applying heavier predicates in argument checking.
5831 (scm_local_eval): Also take memoized object as argument.
5833 * backtrace.c (scm_display_error): Just a safety measure: Stacks
5834 aren't created with zero length, but should such a strange
5835 creature suddenly turn up...
5837 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
5839 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
5840 `del', for the sake of C++ compilers. (Patch applied by JimB.)
5842 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
5844 * variable.c (scm_make_variable): Make the name hint optional, as
5846 (anonymous_variable_sym): Renamed from variable_sym. All uses
5849 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
5850 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
5851 of scm_primitive_load_path was also changed to
5852 "primitive-load-path", from "%try-load-path". Callers changed.
5853 We'd like to respect the convention that a function named
5854 "try-mumble" should behave just like the function called "mumble",
5855 but return #f instead of signalling some error.
5856 * load.h: Rename prototypes.
5858 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5860 * print.c (make_print_state, grow_print_state), print.h: Modified
5861 the print state representation: Don't use a tail array for
5862 recording of circular references. Resizing of the print state
5863 structure invalidates the print state pointer. To avoid passing
5864 around an indirect print state reference to all printing
5865 functions, we instead let the print state reference a resizable
5868 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5870 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
5871 Don't crash when passed an improper list terminated by a
5872 non-immediate value.
5874 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
5876 Allocate data for structures on an eight-byte boundary, as
5877 required by the tagging system.
5878 * struct.c (alloc_struct): New function.
5879 (scm_make_struct, scm_make_vtable_vtable): Call it.
5880 * struct.h (scm_struct_n_extra_words): Bump to 3.
5881 (scm_struct_i_ptr): New "field".
5882 * gc.c (scm_gc_sweep): When we need to free the data, use the
5883 information stored by alloc_struct to find the beginning of the
5884 block allocated to the structure, so we can free it.
5886 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5888 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
5891 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
5892 (scm_debug_info): New member: id.
5894 * stacks.c: Stacks are now represented as structs; Stacks have an
5895 id given to them by `start-stack'.
5896 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
5898 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
5899 Changed stack representation.
5901 * debug.c (scm_procedure_name): Try procedure property `name' for
5902 compiled closures aswell.
5904 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
5906 * eval.c: scm_i_name moved to gsubr.c
5907 (scm_m_define): Record names of all kinds of procedure
5908 objects. (Earlier, only closures were recorded.)
5910 * procprop.h: Added declaration of scm_i_name.
5912 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
5913 (scm_make_gsubr): Record names of compiled closures.
5915 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5917 * debug.c, debug.h: Removed obsolete code.
5919 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
5920 stacks.c: Renamed regs --> scm_contregs.
5922 * print.c (scm_free_print_state): Cleanup print state before
5923 returning it to pool. It is better to do it here than in
5924 scm_prin1 since scm_prin1 is called often.
5926 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
5927 s_set_source_property_x): Check that first argument is a pair or a
5930 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
5931 scm_i_line, scm_i_column and scm_i_breakpoint global.
5933 * init.c: Added #include "backtrace.h" and #include "stacks.h".
5934 (scm_boot_guile_1): Added calls to scm_init_backtrace and
5937 * debug.h: Added debug object smob declaration and macro
5940 * configure.in: Build with backtrace.o and stacks.o if debug
5943 * Makefile.in: Added entries for new files: backtrace.c,
5944 backtrace.h, stacks.c and stacks.h.
5946 * symbols.c (scm_sym2ovcell): Fixed documentation.
5948 * _scm.h (min, max): Added.
5950 * async.c: Moved `min' macro to _scm.h.
5952 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
5953 SCM_BACKTRACE_INDENT.
5955 * eval.c: Added new debug options `maxdepth' and `indent'.
5957 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
5959 * print.h: Added selector SCM_PRINT_STATE.
5961 * print.c: New functions: scm_make_print_state,
5962 scm_free_print_state.
5964 * print.h: Added declarations for scm_make_print_state,
5965 scm_free_print_state.
5967 * debug.c (scm_m_start_stack): New acro.
5969 * debug.h: Small cleanup.
5971 * init.c (scm_boot_guile_1): Moved scm_init_debug below
5974 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

5994 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
5995 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
5996 declare functions with prototypes. (Patch thanks to Marius
5999 More prototype-related changes from Marius Vollmer:
6000 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6001 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6002 * ports.h (ptobfuns): Added prototypes. This means some casting in
6004 * fports.c: Added casts for initializations, since the functions
6005 are defined to take FILE * as their stream argument, not SCM.
6006 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6007 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6008 to `char *str_data' to conform to prototype.
6010 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6012 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6014 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6016 * stime.c, stime.h: use SCM_P method.
6018 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6020 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6021 be given at least two arguments. Insist that lst's last element
6022 be a list, but don't make any requirements of its predecessors.
6024 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6026 * eval.c (scm_nconc2last): Revert last change; there seems to be
6027 other stuff going on here.
6029 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6031 * eval.c (scm_nconc2last): Make sure that each element of lst
6032 (which is a list of argument lists, except for the tail) is a
6033 proper list, i.e., finite and terminated by '().
6035 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6037 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6040 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6041 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6044 * vectors.c (scm_make_vector): Fill vectors with the undefined
6045 value, to help make Guile Scheme code more portable to other
6048 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6049 * symbols.h, tags.h: Doc fixes.
6051 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6053 * async.c (scm_take_signal): Doc fixes.
6055 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6057 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6058 want to subtract it from the modulus; we just want to leave it
6061 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6063 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6066 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6068 * throw.c (scm_catch_apply): Finished implementation of
6071 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6073 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6075 (scm_init_filesys): set "i/o-extensions" feature.
6078 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6080 * Makefile.in (root.o): Correct dependencies.
6082 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6084 * Makefile.in: Added dependency entry for root.o.
6086 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6087 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6089 * init.c (scm_start_stack): Set initial root continuation number
6092 * procs.c: New function: scm_thunk_p.
6094 * procs.h: Added declarations of scm_thunk_p.
6096 * root.c: Renamed `call-with-new-root' -->
6097 `call-with-dynamic-root'.
6098 (cwdr): Removed allocation of new root state. This should be done
6099 separately by use of scm_make_root.
6100 (scm_apply_with_dynamic_root): New function: Does what it
6101 sounds like. Needed when spawning threads.
6103 * root.h: Added member last_debug_frame to root state.
6104 Added #include "libguile/debug.h"
6106 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6107 arguments. The motivation is that code in root.c needs catch
6108 functionality, and we want to avoid code duplication.
6109 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6110 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6111 handlers that run without popping the stack into the dynwind
6114 * throw.h: Added prototypes for scm_catch_apply and
6117 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6119 * root.h (scm_root, scm_set_root): Decouple thread support details
6120 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6121 SCM_SET_THREAD_LOCAL_DATA.
6123 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6124 and tortoise scanning loop.
6126 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6128 * Makefile.in: Rebuild dependencies.
6130 * libguile.h: #include "libguile/print.h" before "smob.h", since
6131 the latter uses the print_state structure.
6133 * throw.c (scm_ithrow): Use the correct variable when checking to
6134 see if a given element of scm_dynwinds is a valid catch.
6136 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6137 structure, abort; don't just silently ignore the garbage.
6139 * _scm.h: #include "print.h" here, since it seems to be used just
6141 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6142 strports.c, unif.h: Don't #include "print.h".
6144 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6146 * feature.h (scm_loc_features): Removed external declaration.
6147 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6149 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6151 * feature.c (scm_init_feature): Added threads feature (needs to be
6152 initialized here, since features doesn't exist when
6153 scm_init_threads is called).
6155 * libguile.h: Added #include "libguile/../threads/threads.h".
6156 (This is a kludge to get thread support working. This should be
6159 * configure.in, acconfig.h: Added flags for thread support.
6161 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6164 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6165 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6168 * _scm.h: Added conditional #include "threads.h"
6170 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6171 SCM_THREADS_SWITCHING_CODE.
6173 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6174 allocate the basic dynamic root object.
6175 (scm_boot_guile): Added call to scm_init_root.
6177 * root.c, root.h: Added root smob.
6178 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6179 functions: Implements dynamic roots mostly according to spec in
6180 SCM manual. Main difference is that the second argument is a
6181 throw handler rather than an error "thunk".
6183 * root.h: Added declaration of scm_init_root.
6185 * root.c: Added #include "genio.h", #include "smob.h", #include
6186 "pairs.h", #include "throw.h", #include "dynwind.h", #include
6188 (scm_init_root): Added #include "root.x".
6190 * throw.c: Added #include "stackchk.h"
6191 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
6192 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
6193 can be used in scm_call_with_new_root; Added reenabling of stack
6194 checking when catching a throw.
6196 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
6198 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
6200 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
6201 element is not found, as per R4RS.
6203 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6205 * list.c: Doc fixes throughout.
6207 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6209 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
6210 declare the char * to be const. Avoids a warning in rgx.c.
6212 * ports.h: spelling fix.
6214 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
6217 * load.c (scm_sys_try_load_path): throw an error if file not found
6218 (like it says it in NEWS).
6220 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6222 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
6223 PROPS slot to '(), not #f; it's an empty alist.
6225 * throw.h, throw.c: Use SCM_P instead of #if hair.
6227 Remove special support for uncaught throws; see throw.c for
6229 * throw.c (uncaught_throw): New function.
6230 (scm_ithrow): Call uncaught_throw if we don't find a throw
6231 target; don't mess with scm_bad_throw_vcell.
6232 (scm_bad_throw_vcell): Variable deleted.
6233 (scm_init_throw): Don't initialize it.
6235 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
6238 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6240 * numbers.c (scm_istr2int): If the number is short (as most
6241 numbers are), just call scm_small_istr2int to deal with it.
6242 (scm_small_istr2int): New function, created by un-#ifdefing the
6243 non-bignum version of scm_istr2int and renaming it.
6245 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
6247 * load.c (scm_sys_try_load): don't check whether value returned
6248 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
6249 Change the Scheme name from %try-load to primitive-load.
6251 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
6252 Can avoid passing a message, allowing it to be derived in the
6253 error handler (e.g., if we want to throw to the key both from
6256 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
6258 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
6259 references now have a new appearance which is more compact and
6260 also gives a clue about what the target of the reference is.
6261 By setting parameters in the print state, more fancy printing can
6262 be achieved. This is used by the (not yet commited) backtrace
6265 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
6267 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
6270 * print.c: Added #include "struct.h". Removed function
6273 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
6274 scm_iprin1. Removed prototype for scm_prlist.
6276 * arbiters.c (prinarb),
6277 async.c (print_async),
6278 debug.c (prindebugobj, prinmemoized),
6279 eval.c (prinprom, prinmacro),
6280 filesys.c (scm_fd_print, scm_dir_print),
6282 mallocs.c (prinmalloc),
6283 numbers.c, numbers.h (scm_floprint, scm_bigprint),
6284 smob.h (scm_smobfuns),
6285 srcprop.c (prinsrcprops),
6287 unif.c, unif.h (scm_raprin1, rapr1),
6288 variable.c (prin_var): Changed argument `int writing' to
6289 `scm_print_state *pstate'.
6291 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
6292 that it will be called before scm_init_print.
6294 * print.c (scm_prin1): Print states are now allocated when calling
6295 scm_prin1 and then passed around to all printing functions as an
6296 argument. A cache `print_state_pool' enables reuse of print
6298 (scm_make_print_state): New function.
6299 (scm_iprin1): Adaption to print states.
6300 (scm_iprlist): An initial "hare and tortoise" scan brings down
6301 time complexity to O (depth * N). (Better time complexity will be
6302 achieved when the printing code is completely rewritten.)
6304 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6306 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
6307 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
6308 it gets done whether or not the cache variable has a value.
6310 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6312 Distinguish #f and ().
6313 * __scm.h: #undef SICP.
6314 * pairs.h (SCM_EOL): Delete this definition, equating it with
6316 * tags.h (SCM_EOL): Give it a new definition here; I think I found
6317 the value it used to have. Doc fixes, too.
6319 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
6321 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
6322 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
6323 Lord's implementation of structs, allowing for tail arrays as
6324 described in the manual. Also fixed some bugs. (Both the interface
6325 and the implementation should be improved.)
6327 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
6329 * print.c, print.h: Closures now print like #<procedure foo (x)>.
6330 People who whish to see the source can do `(print-enable 'source)'.
6331 Removed #ifdef DEBUG_EXTENSIONS.
6333 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6335 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
6336 integer (assuming for now accepting an integer is a good thing).
6338 * error.c, fports.c: replace use of %S in lgh_error args with %s.
6339 %S will be used instead for write'ing arguments.
6341 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
6342 asserts. fix a few other asserts.
6343 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
6344 scm_uniform_vector_ref, scm_array_set_x,
6345 scm_dimensions_to_unform_array): change args in
6346 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
6347 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
6348 scm_substring_fill_x): likewise.
6349 gsubr.c (scm_gsubr_apply): likewise.
6350 eval.c (SCM_APPLY): likewise.
6352 * eval.c (4 places): replace scm_everr with lgh_error or
6355 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
6356 scm_memory_error): new procedures.
6357 scm_everr: deleted. can use scm_wta, dropping first two args.
6358 scm_error: convert NULL subr to SCM_BOOL_F.
6360 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
6363 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
6366 * error.c, error.h: new error keys: scm_arg_type_key,
6367 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
6369 scm_wta: reimplement using lgh_error instead of scm_everr.
6371 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
6373 * gdbint.c: scm_lread now has one more argument.
6375 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
6376 scm_port_\1; Added mutator scm_set_port_filename_x (used when
6377 loading source from non-file ports, which, e. g., happens when
6378 using the Emacs interface).
6380 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
6383 * read.c: Added code for recording of positions of source code
6384 expressions; New functions: recsexpr, scm_lreadrecparen;
6385 _scm_make_srcprops --> scm_make_srcprops
6386 (scm_flush_ws): Removed updating of positions counters. This work
6387 is already done by scm_gen_getc
6389 * read.h: Added prototype for scm_lreadrecparen
6391 * print.c: Added #include "alist.h"
6393 * eval.c: Added #include "hash.h"
6395 * eq.c: Added #include "ramap.h"
6397 * options.c: Documentation fixes.
6399 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
6400 (scm_init_srcprop): Adjusted size of initial source-whash. Name
6401 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
6402 --> scm_make_srcprops
6404 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
6405 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
6406 function calls in the definition of the whash access macros.
6408 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
6410 * init.c (scm_boot_guile): Add level of indirection to
6411 scm_boot_guile_1() to ensure that stack base pointer is properly
6412 initialized. There was no guarantee that variable i was the
6413 highest/lowest variable on stack (i.e. the call frame of
6414 scm_boot_guile was not completely protected from gc).
6416 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
6418 * ports.h (scm_port_table): put back file_name, it will be used to
6419 support debugging. Undo related changes in fports.c, ioext.c,
6422 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6424 * ports.h (scm_port_table): remove file_name member for now, it seems
6426 * fports.c (scm_open_file): don't set file_name in PTAB.
6427 (prinfport): don't use file_name in PTAB.
6428 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
6429 * ports.c (scm_add_to_port_table): don't intialize file_name.
6430 (scm_port_file_name): remove for now.
6431 * gc.c (scm_gc_mark): don't mark PTAB file_name.
6433 * fports.h (scm_mkfile): prototype deleted.
6434 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
6436 * debug.c, unif.c: use scm_out_of_range instead of
6437 wta for range errors (ASSERT still needs work).
6439 * error.c, error.h (scm_out_of_range): new procedure.
6441 * error.c, error.h (scm_out_of_range_key): new key.
6443 * posix.c (scm_sync): #else was missing.
6445 * error.c, error.h: append _key to names scm_num_overflow and
6448 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
6449 of consing an empty list.
6450 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
6451 of macros, saves code and string space.
6452 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
6453 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
6454 lower case. Rename scm_syserror_m to scm_syserror_msg.
6455 error.h: prototypes for new procedures.
6457 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
6459 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
6461 * error.c, error.h: setup scm_num_overflow key.
6463 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
6464 Remove definition of SCM_OVSCM_FLOW.
6466 * fports.c (scm_open_file): use SCM_SYSERROR_M.
6468 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
6469 explicit message and args.
6471 * error.c, error.h, __scm.h: change system_error_sym to
6474 * error.c (system_error_sym): remove leading %% from the Scheme name
6477 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
6479 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6481 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
6482 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
6483 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
6484 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
6485 renamed. (These were introduced by unsupervised name
6488 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6490 * print.c: Added code for detection of circular references during
6491 printing. (init_ref_stack, grow_ref_stack): New functions. Added
6492 a hook for printing of closures (accessible via print options).
6493 This leads to a split of calls to scm_iprin1 into two classes:
6494 elementary print operations (e. g. the code which prints a smob)
6495 still use scm_iprin1 while top level calls (like scm_display) use
6496 scm_prin1. scm_prin1 begins by clearing the data structure used
6497 to record reference information.
6499 * print.h: Added declarations of scm_prin1 and scm_prlist.
6501 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
6503 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
6505 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
6507 * error.c (err_head): scm_iprin1 --> scm_prin1
6509 * debug.c: Adjusted header comment.
6513 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6515 * strerror.c: Doc fix.
6517 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6519 * gdbint.c (gdb_read): Now possible to run during GC.
6520 (unmark_port, remark_port): New functions.
6522 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
6524 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
6525 of allocating a new string object. Also, increase size by
6526 the factor 2 instead of 1.5.
6528 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
6530 * __scm.h (SCM_P): Corrected to run under traditional C.
6532 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
6535 * async.c: Calls to scm_sysintern corrected.
6537 * async.h (scm_async_clock): Redundant declaration removed.
6539 * continuations.c (scm_dynthrow): Redundant declaration removed.
6541 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
6542 Definition typos corrected.
6544 * debug.h: Missing declarations of functions in debug.c added
6547 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
6548 Missing declarations to functions in eval.c added.
6550 * filesys.c: Possibly uninitialized variable rv.
6552 * gc.h (scm_object_addr, scm_unhash_name): Missing
6553 declarations of functions defined in gc.c added.
6555 * genio.c: Possible typos str_data -> wstr_data. ???
6557 * genio.c: Possibly unintended shadowing of local variable
6558 `int c' (gotos out of scope of inner `c'). ???
6560 * init.c: Uninitialized `SCM last' may be used.
6562 * ioext.h: (scm_sys_isatty_p): Typo.
6564 * list.h (scm_list_head): Missing prototype for function in
6567 * numbers.c (scm_two_doubles): Changed from extern to static
6568 (is used only within numbers.c).
6570 * numbers.h: Repeated declarations removed.
6572 * ports.h (scm_close_all_ports_except): Declaration for the
6573 function defined in ports.c added.
6575 * posix.h: Missing declarations added.
6577 * procs.h (scm_make_subr_opt): Missing declaration added.
6579 * socket.h (scm_sys_gethost): Missing declaration added.
6581 * socket.h: Redundant declarations removed (they are in fdsocket.h).
6583 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
6584 Missing declarations added.
6586 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
6588 * struct.c: Uninitialized variable `SCM answer' may be used.
6590 * unif.c (l2ra): Declaration prototype.
6592 * unif.c (scm_array_equal_p): Dummy definition removed (it is
6593 defined in ramap.c).
6595 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
6596 Redundant declarations removed (they are in ramap.h).
6598 * variable.h (scm_make_udvariable,
6599 scm_make_undefined_variable): Declaration corrected to
6600 correspond variable.c.
6602 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
6603 Missing declarations added.
6605 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
6607 * Makefile.in (distclean): Don't forget to delete fd.h.
6609 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6611 * fd.h.in, tags.h: Trivial cleanups.
6613 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
6614 marksweep.h just declared functions from gc.c.
6615 * gc.h, libguile.h: Don't #include "marksweep.h".
6616 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
6617 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
6618 dependencies updated.
6620 * libguile.h: Don't #include "files.h"; it's been deleted.
6622 * files.c (scm_sys_delete_file): Moved to filesys.c.
6623 File is now empty; deleted.
6625 * filesys.c: scm_sys_delete_file is now here. Remove
6626 #if's; they seem to rely on remnants of an old portability
6627 regimen. If the problems come up again, solve them properly,
6628 using autoconf. Specifically: Don't test M_SYSV, and #define
6629 remove to be unlink if it's #defined; don't use remove just
6630 because HAVE_STDC_HEADERS is #defined.
6631 * filesys.h: Add declarations for scm_sys_delete_file.
6632 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
6633 files.o, files.h, files.c, and files.x.
6634 * init.c: Don't #include "files.h", and don't call scm_init_files.
6636 Use SCM_P instead of PROTO; the latter intrudes on the user's
6638 * params.h: Deleted; definition of SCM_P moved to...
6639 * __scm.h: ... here, where it replaces PROTO macro.
6640 * libguile.h, smob.h: Don't #include "params.h".
6641 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
6642 smob.h: Fix prototypes accordingly.
6643 * Makefile.in: Update dependencies.
6644 (inner_h_files): Remove params.h.
6646 * gc.c: #include "gc.h"; every module should include its header,
6647 to let the compiler cross-check the declarations against the
6650 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
6651 simpos.h: #include "libguile/__scm.h".
6653 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
6655 * init.c: Don't forget to #include smob.h and init.h.
6656 * Makefile.in: Dependencies updated.
6658 * smob.h: Use PROTO instead of #if __STDC__.
6660 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
6662 * __scm.h: Doc fixes.
6664 * __scm.h, libguile.h: Use "quotes" in the #includes, not
6665 <angles>; this allows `make depends' to work properly.
6667 * libguile.h: #include smob.h and pairs.h before the others; they
6668 define typedefs used by other headers.
6670 C files should #include only the header files they need, not
6671 libguile.h (which #includes all the header files); the pointless
6672 recompilation was wasting my time.
6673 * Makefile.in (all .o dependency lists): Regenerated.
6674 * libguile.h: Don't try to get a definition for size_t here...
6675 * __scm.h: Do it here.
6676 * _scm.h: Since this is the internal libguile header, put things
6677 here that all (or a majority) of the libguile files will want.
6678 Don't #include <libguile.h> here; that generates dependencies on
6679 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
6680 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
6681 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

6761 * stime.c: Get "stime.h"."libguile/continuations.h".
6762 * strings.c: Get "strings.h", "chars.h".
6763 * strop.c: Get "strop.h", "chars.h".
6764 * strorder.c: Get "strorder.h", "chars.h".
6765 * strports.c: Get "strports.h", "print.h", "eval.h", "unif.h".

6771 "dynwind.h", "eval.h", "alist.h", "smob.h", "genio.h".
6772 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",
6773 "smob.h", "genio.h", "eval.h", "chars.h".
6774 * variable.c: Get "variable.h", "smob.h", "genio.h".

6777 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
6778 * weaks.c: Get "weaks.h".
6780 * stackchk.h: #include "libguile/debug.h",
6782 * print.h, read.h: #include "options.h", since everyone who uses
6783 either of these files will need that.
6785 * smob.h: #include "ports.h", "genio.h", and "print.h", since
6786 anyone who uses this file will need them to define the smob
6787 printing functions. Also, get markers.h, since people will need
6788 to #define the mark functions.
6790 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
6791 * ports.h: ... to here.
6793 * ports.h (scm_port_table_size): Explicitly give type as 'int';
6794 don't rely on archaic C default type rules.
6796 * fports.h: #include "libguile/ports.h", since you need that in
6797 order to parse this.
6799 * genio.h: #include "libguile/print.h", because you need that to
6800 parse this; don't bother #including "ports.h", since print.h gets
6803 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
6805 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
6806 this; it's now a reference to an element of *scm_root.
6808 * debug.h: Don't #include "options.h"; the compiler won't be able
6809 to find that once the headers are installed; instead, #include
6810 "libguile/options.h".
6811 * gc.h: Same, with marksweep.h.
6812 * mbstrings.h: Same, with symbols.h.
6813 * scmhob.h: Same, with _scm.h.
6814 * smob.h: Same, with params.h.
6816 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
6817 C files; there's no need for this, and it forces recompilations
6820 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
6822 * error.c (scm_error): declare scm_error_callback.
6824 * error.h: prototype for scm_error_callback.
6826 * __scm.h: define lgh_error.
6827 (SCM_SYSERROR): redefine using lgh_error.
6829 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
6831 * error.c (scm_error): new procedure.
6833 * error.h: prototype for scm_error.
6835 * Makefile.in (install): install scmconfig.h from the current
6836 directory, not $(srcdir).
6838 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
6840 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
6841 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
6842 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
6843 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
6844 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
6845 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
6846 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
6847 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
6848 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
6849 vports.h, weaks.h: #include "libguile/__scm.h", not
6850 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
6851 dependencies are within libguile properly.
6853 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
6855 * Makefile.in (.c.x): Simplify; there's no need to run this rule
6856 when scmconfig.h doesn't exist.
6858 * load.c (scm_sys_try_load): Correct spelling.
6860 * feature.c (scm_loc_features): Make this static.
6862 * Makefile.in (libpath.h): Omit trailing slash from path. We
6863 shouldn't require it of users, so why put it here?
6865 Move code to initialize and search %load-path from ice-9 to C
6866 code, so we can use the load-path to find the ice-9 boot code;
6867 this makes it easier to run Guile without installing it. See
6868 corresponding changes in guile/Makefile.in.
6869 * feature.c: Move stuff concerned with the load path to load.c.
6870 (scm_compiled_library_path): Deleted.
6871 Don't #include libpath.h here.
6872 * feature.h: Don't mention scm_compiled_library_path.
6873 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
6874 <sys/stat.h>, and <unistd.h> (if present).
6875 (R_OK): #define if the system hasn't deigned to.
6876 (scm_loc_load_path): New variable.
6877 (scm_init_load_path, scm_sys_search_load_path,
6878 scm_sys_try_load_path): New functions.
6879 (scm_init_load): Initialize scm_loc_load_path to point to the
6880 value cell of the Scheme %load-path variable.
6881 * load.h: Add declarations for scm_sys_search_load_path,
6882 scm_sys_try_load_path.
6883 * init.c: Call scm_init_load_path.
6884 * Makefile.in (feature.o, load.o): Dependencies updated.
6886 * load.c, load.h: Rewrite using PROTO macro.
6888 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6890 * gc.c (scm_cellp): New function: C predicate to determine if an
6891 SCM value can be regarded as a pointer to a cell on the heap.
6893 * gc.h: Added declaration of scm_cellp.
6895 * gdb_interface.h: New file: The GDB interface header from the GDB
6898 * gdbint.c: New file: GDB interface.
6900 * gdbint.h: New file: GDB interface.
6902 * libguile.h: Added #include <libguile/gdbint.h>.
6904 * init.c (scm_boot_guile): Added scm_init_gdbint.
6906 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
6907 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
6908 found if object files and source are kept separate).
6910 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
6912 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
6914 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
6916 * configure.in: Don't substitute the values of TCL_SRC_DIR and
6917 TK_SRC_DIR; they're not relevant any more.
6919 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
6920 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
6922 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
6924 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
6925 search path, so we can find the <libguile/MUMBLE.h> headers.
6927 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
6929 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
6930 implicit in the .c.o rule.
6931 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
6934 Put the library path in a header file, instead of passing it on
6935 the command line in every compilation.
6936 * Makefile.in (libpath.h): New target.
6937 (feature.o): Depend on libpath.h.
6938 (clean): Delete libpath.h.
6939 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
6940 * feature.c: ... #include "libpath.h" here.
6941 * .cvsignore: Ignore libpath.h.
6943 Don't install the unwashed masses of Guile header files in the
6944 main #include path; put most of them in a subdirectory called
6945 'libguile'. This avoids naming conflicts between Guile header
6946 files and system header files (of which there were a few).
6947 * Makefile.in (pkgincludedir): Deleted.
6948 (innerincludedir): New variable; this and $(includedir) are enough.
6949 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
6950 (installed_h_files): Divide this up. Now this variable lists
6951 those header files which should go into $(includedir) (i.e. appear
6952 directly in the #include path), and ...
6953 (inner_h_files): ... this new variable says which files appear in
6954 a subdirectory, and are referred to as <libguile/mumble.h>.
6955 (h_files): List them both.
6956 (install): Create innerincludedir, not pkgincludedir. Put
6957 the installed_h_files and inner_h_files in their proper places.
6958 (uninstall): Corresponding changes.
6959 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
6960 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
6961 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
6962 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
6963 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
6964 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
6965 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
6966 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
6967 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
6968 vports.h, weaks.h: Find __scm.h in its new location.
6969 * __scm.h: Find scmconfig.h and tags.h in their new locations
6970 (they're both "inner" files).
6972 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
6974 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
6976 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6978 * posix.c: Doc fixes.
6980 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
6982 * socket.c: Don't include a prototype for inet_aton; just use a
6983 K&R style declaration, to avoid warnings but minimize the chance
6984 of conflicts with the system.
6986 On NextStep, <utime.h> doesn't define struct utime, unless we
6987 #define _POSIX_SOURCE before #including it.
6988 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
6989 * acconfig.h: New comment text for above CPP symbol.
6990 * configure.in: Call it.
6991 * posix.c: #define _POSIX_SOURCE if it seems necessary.
6993 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
6995 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
6996 testing for __EMX__.
6998 * posix.c: #include <libc.h>, if it exists.
7000 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7001 don't even know if the latter exists.
7003 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7004 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7005 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7007 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7009 (scm_init_posix): Use them when initializing the Scheme constants
7012 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7014 * Makefile.in (libdir, includedir, bindir): Use the
7015 autoconf-supplied values, instead of deriving them ourselves.
7016 (pkgincludedir, datadir, pkgdatadir): New variables.
7017 (install, uninstall): Put the header files in a special
7018 subdirectory, not in the main search path.
7020 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7021 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7023 * Makefile.in (IMPLPATH): Deleted; never used.
7025 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7026 on the Tcl/Tk source any more.
7027 (INCLUDE_CFLAGS): Remove references to the above.
7029 * Makefile.in (version.o): Corrected dependencies.
7031 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7033 * libguile.h: #include "version.h"
7035 * init.c (scm_boot_guile): Call scm_init_version.
7036 * gscm.c (gscm_run_scm): Call scm_init_version.
7038 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7039 GUILE_VERSION): AC_DEFINE these.
7040 (acconfig.h): #undef the above symbols.
7042 * Makefile.in (libobjs): Add version.o.
7043 (installed_h_files): Add version.h.
7044 (c_files): Add version.c.
7045 (gen_c_files): Add version.x.
7046 (version.o): New rule.
7047 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7048 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

7056 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7057 weaks.o): Add version.h to dependency lists.
7058 (markers.o): Remove duplicate rule.
7060 * version.h: New file.
7062 * version.c: New file.
7064 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7066 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7067 array; use it appropriately. Since GCC is quite happy to
7068 subscript functions, it never warned us about this; we should use
7069 -Wpointer-arith in the future. I guess we never tested
7072 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7074 * socket.c: Doc and copyright fixes.
7076 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7078 * debug.c: Fixed and improved gdb support.
7080 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7082 * socket.c: Added declaration of inet_aton to avoid compiler
7083 warning. (Hope this solution is correct.)
7085 * stime.c: Added declaration of ftime. (This is missing in
7088 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7090 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7092 * Makefile.in (c_files): add strerror.c.
7094 * strerror.c: new file from Emacs' sysdep.c.
7095 maybe configure should also check for sys_errlist.
7097 * configure.in (AC_REPLACE_FUNCS): add strerror.
7099 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7101 * debug.c (scm_init_debug): Added initialization for
7102 scm_evaluator_traps.
7104 * debug.h, debug.c: Various name changes.
7105 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7106 "debug-options-interface". See commentary in options.c.
7108 * options.h, options.c: Options now have documentation strings.
7109 Also added a long explanatory commentary.
7111 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7114 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7115 last_debug_info_frame is now updated in all cases.
7117 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7120 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7122 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7123 Added option STACK_CHECKING.
7125 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7127 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7129 * __scm.h: Removed symbols for debugging support.
7131 * acconfig.h: Added symbols for debugging support.
7133 * configure.in: Added user option for debugging support.
7134 --enable-debug will include the debugging code into libguile.a.
7136 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7137 scm_relocate_chunk_to_heap.
7139 * debug.c: New file: low-level debugging support. It also
7140 includes support for debugging with gdb. (The extensions to gdb
7141 are written by Per Bothner at Cygnus.)
7143 * debug.h: New file: low-level debugging support.
7145 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7146 argument pairs. Extensive modifications to the debugging
7147 evaluator. Added "SECTION:" commentaries to clarify what happens
7148 when, during double compilation. Renamed EVALIMP --> EVALIM.
7149 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7150 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7151 the beginning of the file. New procedure: scm_unmemocopy.
7152 Added some global state variables needed by the debugging
7153 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7154 check_entry, check_apply, check_exit, debug_options and
7155 evaluator_traps. New acro: undefine.
7157 * eval.h: Renamed EVAL --> XEVAL.
7159 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7160 --> scm_make_weak_key_hash_table.
7162 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7163 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7165 * libguile.h: Conditionally include debug.h
7167 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7168 scm_object_properties shouldn't return handle. `handle' now gets
7169 initialized in scm_set_object_properties_x. scm_object_properties
7170 doesn't any longer create an entry in scm_object_whash.
7172 * options.c: New file: handling of run time options.
7174 * options.h: New file: handling of run time options.
7176 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7178 * print.c: New procedure: scm_print_options
7180 * print.h: Defines for print options.
7182 * read.c: New procedure: scm_read_options
7184 * read.h: Defines for reader options.
7186 * root.h: Added scm_source_whash among scm_sys_protects.
7188 * srcprop.c: New file: source properties.
7190 * srcprop.h: New file: source properties.
7192 * throw.c (jbsmob): Jump buffers are now correctly allocated.
7193 (Bug found by A. Green.)
7195 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7197 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7199 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
7201 * libguile.h: #include "objprop.h"; I guess this was forgotten.
7203 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
7204 and should be called by the final client.
7206 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
7208 * gc.h: Use the PROTO macro when declaring functions.
7209 * gc.c: Use the PROTO macro when declaring static functions.
7210 Remove the CPP hair around function definitions.
7212 * gc.c (scm_init_storage): Initialize scm_asyncs.
7214 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
7215 preprocessor symbol; "__scm.h" is where it might get #defined.
7216 * __scm.h: Similar: #include <scmconfig.h> before testing
7219 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
7221 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
7223 * init.c (scm_boot_guile): Add init_func argument; call
7224 (*init_func) instead of calling scm_appinit; it's ucky to
7225 hard-code names for the user's procedures.
7226 * init.h (scm_boot_guile): Adjust declaration.
7228 * __scm.h (PROTO): New macro, for declaring functions with
7231 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
7232 eliminate all the __STDC__ conditionals.
7233 (scm_boot_guile): Add declaration.
7234 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
7235 Remove __STDC__ conditionals around function definitions; the
7236 declarations in init.h will provide the same information, more
7239 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
7240 complain about it in the error message; the error message is
7241 adequate without that note, and there's nothing the user can do
7244 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
7246 * Makefile.in (ancillary): Drop def.sed.
7248 * posix.c (scm_init_posix): Use numeric values, rather than
7249 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
7250 F_OK. The symbols aren't available on some systems, and I'm
7251 pretty sure their values are fixed by common widespread practice.
7252 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
7254 More functions unavailable on some systems.
7255 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
7256 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
7258 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7259 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
7260 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
7261 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
7262 stub that signals an error as the #else.
7264 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
7266 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
7268 * Fixes motivated by Petr Adamek <adamek@mit.edu>:

7297 genio.c, simpos.c, vports.c: include string.h.
7299 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
7301 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
7303 (scm_addr_buffer_size): change type from scm_sizet to int.
7304 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
7305 from scm_sizet to int.
7307 * error.c: include unistd.h.
7309 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
7312 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
7314 * __scm.hd, def.sed: deleted.
7316 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
7318 Changes for NeXT, suggested by Robert Brown.
7319 * configure.in: Call AC_TYPE_MODE_T.
7320 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
7321 NeXT. Put header file list in alphabetical order.
7322 * configure, scmconfig.h.in: Regenerated.
7323 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
7325 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
7328 * acconfig.h: New file, providing documentation for the CPP
7329 symbols defined in configure.in
7330 * acconfig-1.5.h: Removed; superceded by the above.
7332 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
7334 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
7336 * fports.c (scm_open_file): don't return #f, throw error.
7338 * ioext.c (fileno): renamed from %fileno.
7339 (soft-fileno): deleted.

7343 (scm_set_port_revealed_x): return unspecified, not #f.
7345 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
7347 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
7349 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
7351 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
7353 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7355 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
7356 This is necessary on Ultrix, and doesn't hurt portability.
7358 * Makefile.in (dist-dir): New target, implementing a new dist system.
7359 (installed_h_files): Put in alphabetical order.
7360 Remove duplicate entries for markers.h and unif.h.
7361 (c_files): Remove duplicate entries for markers.c.
7362 (ancillary): Renamed from anillery; all uses changed. Remove
7363 PLUGIN; it's a directory, and needs special treatment in dist-dir.
7364 Remove all the ../doc/* files; doc/Makefile.in handles that.
7366 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
7368 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
7369 every if must have an else, or else the whole command has a
7370 non-zero exit code whenever the if's condition is false.
7372 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
7374 * posix.c: include string.h.
7376 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7378 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
7381 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
7382 Remove leading % from scheme names.
7383 Do not return error values, call SCM_SYSERROR or similar.
7385 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
7387 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
7389 * struct.c (scm_init_struct): new file.
7391 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>

7394 (scm_list_head): added list-head for rapidly chopping argument
7395 lists off of longer lists (and similar).

7400 handle for obj, not the handle itself.
7402 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
7404 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
7405 weak hash tables last of all marking to avoid an obscure gc bug.
7406 WARNING: circular lists stored in a weak hash table will hose us.
7408 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
7410 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):

7425 * strports.c (scm_strprint_obj): convenience function. C for
7426 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))

7432 Initialization specific to tcl interpreters removed.
7434 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
7436 * ports.c (scm_ports_prehistory): size malloced here doesn't
7437 matter so long as it is non-0 (got rid of "* 4").
7439 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
7441 * gscm.h: gscm_mkarray eliminated (presumably was not being used
7442 since its definition was bogus).
7444 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
7446 * mallocs.[ch]: back again (for rx at least).
7448 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
7450 * ports.c: removed functions relating to the mapping between ports
7451 and descriptors. (That stuff is unix-specific and should be collected
7452 in a separate library).
7454 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
7455 (Tom Mckay@avanticorp.com)
7457 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
7459 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
7460 handled correctly (SCM_FREEP was applied to them) -- test for
7461 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
7462 being overwritten with #f. (brown@grettir.bibliotech.com)

7506 (possibly triggering gc) before setting the tag of the corresponding
7509 * pairs.c (scm_delq_x): never throw an error.
7511 * vectors.c (scm_make_vector): made the default vector fill argument
7512 into '() (much more useful than the previous value, "#unspecified")

7516 * ports.c (scm_add_to_port_table): Added fields
7517 to port table entries: file_name, line_num, col.
7518 Update these in open_file, gen_getc and gen_ungetc.
7519 Added procedures to access those fields.
7521 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
7523 * procs.c (scm_make_subr_opt): new entry point for making

7562 NOTE: this should throw a resumable exception with parameters --
7563 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?

7592 * objprop.c (scm_set_object_property_x &c): use the generic
7593 hashing functions and be threadsafe.

7596 (per suggestion jaffer@gnu.ai.mit.edu).
7598 * mbstrings.c (scm_multi_byte_string): guard against argument list
7601 * strings.c (scm_make_string): loop cleanup

7629 initialization to fix a race condition.
7631 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

7655 set the multi_byte flag correctly in symbols. This is wrong.
7656 intern_obbary_soft and msymbolize should take an extra parameter.
7657 Also, weird multibyte symbols don't print correctly.
7658 The weird symbol syntax is also a bit bogus (emacs doesn't quite
7661 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
7663 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
7664 use the system symhash. == #t means create an uninterned symbol.
7666 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
7668 * strings.c (scm_make_shared_substring): build'em.
7669 It might better to keep a table of these and use one
