guile/libguile/ChangeLog

Fri Aug 30 16:01:30 1996  Jim Blandy  <jimb@floss.cyclic.com>

	* Makefile.in (libdir, includedir, bindir): Use the
	autoconf-supplied values, instead of deriving them ourselves.
	(pkgincludedir, datadir, pkgdatadir): New variables.
	(install, uninstall): Put the header files in a special
	subdirectory, not in the main search path.

	* Makefile.in (ALL_CFLAGS): Provide the proper value for
	LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir). 

	* Makefile.in (IMPLPATH): Deleted; never used.
	
	* Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
	on the Tcl/Tk source any more.
	(INCLUDE_CFLAGS): Remove references to the above.

	* Makefile.in (version.o): Corrected dependencies.

Thu Aug 29 23:06:19 1996  Thomas Morgan  <tmorgan@gnu.ai.mit.edu>

	* libguile.h: #include "version.h"

	* init.c (scm_boot_guile): Call scm_init_version.
	* gscm.c (gscm_run_scm): Call scm_init_version.

	* configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
	GUILE_VERSION): AC_DEFINE these.
	(acconfig.h): #undef the above symbols.

	* Makefile.in (libobjs): Add version.o.
	(installed_h_files): Add version.h.
	(c_files): Add version.c.
	(gen_c_files): Add version.x.
	(version.o): New rule.
	(alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
	chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
	fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
	genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
	mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
	objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
	procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
	simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
	strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
	throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
	weaks.o): Add version.h to dependency lists.
	(markers.o): Remove duplicate rule.

	* version.h: New file.

	* version.c: New file.

Thu Aug 29 15:21:39 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* symbols.c (scm_strhash): scm_downcase is now a function, not an
 	array; use it appropriately.  Since GCC is quite happy to
 	subscript functions, it never warned us about this; we should use
 	-Wpointer-arith in the future.  I guess we never tested
 	case-insensitivity.

Wed Aug 28 18:52:22 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* socket.c: Doc and copyright fixes.

Sat Aug 24 05:29:19 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

	* debug.c: Fixed and improved gdb support.

Fri Aug 23 18:00:16 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

	* socket.c: Added declaration of inet_aton to avoid compiler
 	warning.  (Hope this solution is correct.)

	* stime.c: Added declaration of ftime.  (This is missing in
	Solaris 2 headers.)

Fri Aug 23 02:03:32 1996  Gary Houston  <ghouston@actrix.gen.nz>

	* configure, scmconfig.h.in: Updated, using autoconf and autoheader.

	* Makefile.in (c_files): add strerror.c.

	* strerror.c: new file from Emacs' sysdep.c.
	maybe configure should also check for sys_errlist.

	* configure.in (AC_REPLACE_FUNCS): add strerror.

Fri Aug 23 03:02:46 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

	* debug.c (scm_init_debug): Added initialization for
	scm_evaluator_traps.

	* debug.h, debug.c: Various name changes.
	(Mostly prefixing with SCM_.)  Renamed "debug-options" -->
	"debug-options-interface".  See commentary in options.c.

	* options.h, options.c: Options now have documentation strings.
	Also added a long explanatory commentary.
	
	* eval.c, print.h, print.c, read.h, read.c: Modifications to
	run-time options.

	* gscm.c, init.c, root.c, throw.c: Bug fixes:
	last_debug_info_frame is now updated in all cases.

	* __scm.h, stackchk.h, stackchk.c: Guile now performs stack
	checking.

Thu Aug 22 17:34:17 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

	* __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
	Added option STACK_CHECKING.

Tue Aug 20 18:48:40 1996  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* Makefile.in: Added {debug,options,srcprop}.{h,c}
	
	* __scm.h: Removed symbols for debugging support.

	* acconfig.h: Added symbols for debugging support.

*	* configure.in: Added user option for debugging support.
	--enable-debug will include the debugging code into libguile.a.

	* continuations.c (scm_make_cont): Enlarged the #if 0 around
	scm_relocate_chunk_to_heap.
	
*	* debug.c: New file: low-level debugging support.  It also
 	includes support for debugging with gdb.  (The extensions to gdb
 	are written by Per Bothner at Cygnus.)

	* debug.h: New file: low-level debugging support.

*	* eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
 	argument pairs.  Extensive modifications to the debugging
 	evaluator.  Added "SECTION:" commentaries to clarify what happens
 	when, during double compilation.  Renamed EVALIMP --> EVALIM.
  	Renamed EVAL --> XEVAL.  Removed function evalcar.  Defined
 	evalcar to scm_eval_car.  Added explanation of "EVAL" symbols to
 	the beginning of the file.  New procedure: scm_unmemocopy.
	Added some global state variables needed by the debugging
	evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
	check_entry, check_apply, check_exit, debug_options and
	evaluator_traps.  New acro: undefine.
	
	* eval.h: Renamed EVAL --> XEVAL.

	* gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
	--> scm_make_weak_key_hash_table.
	
	* init.c (scm_restart_stack, scm_boot_guile): Added initialization
	of SCM_DFRAME.  Added calls to scm_init_{debug,options,srcprop}.
	
	* libguile.h: Conditionally include debug.h

*	* objprop.c (scm_object_properties, scm_set_object_properties_x):
 	scm_object_properties shouldn't return handle.  `handle' now gets
 	initialized in scm_set_object_properties_x.  scm_object_properties
	doesn't any longer create an entry in scm_object_whash.
	
*	* options.c: New file: handling of run time options.
	
	* options.h: New file: handling of run time options.

	* posix.c (scm_getpgrp): Cast pointer to getpgrp.
	
*	* print.c: New procedure: scm_print_options

	* print.h: Defines for print options.
	
*	* read.c: New procedure: scm_read_options

	* read.h: Defines for reader options.

	* srcprop.h: New file: source properties.
	
	* throw.c (jbsmob): Jump buffers are now correctly allocated.
	(Bug found by A. Green.)

*	* weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
	
	* weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.

Thu Aug 15 02:05:14 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* libguile.h: #include "objprop.h"; I guess this was forgotten.

	* init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
	and should be called by the final client.

Wed Aug 14 21:41:37 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* gc.h: Use the PROTO macro when declaring functions.
	* gc.c: Use the PROTO macro when declaring static functions.
  	Remove the CPP hair around function definitions.

	* gc.c (scm_init_storage): Initialize scm_asyncs.

	* libguile.h: #include "__scm.h" before testing the STDC_HEADERS
	preprocessor symbol; "__scm.h" is where it might get #defined.
	* __scm.h: Similar: #include <scmconfig.h> before testing
	HAVE_LIMITS_H.

	* __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
	
Fri Aug  9 11:09:28 1996  Jim Blandy  <jimb@totoro.cyclic.com>

*	* init.c (scm_boot_guile): Add init_func argument; call
	(*init_func) instead of calling scm_appinit; it's ucky to
	hard-code names for the user's procedures.
	* init.h (scm_boot_guile): Adjust declaration.

	* __scm.h (PROTO): New macro, for declaring functions with
	prototypes.

	* init.h (scm_start_stack, scm_restart_stack): Use PROTO;
	eliminate all the __STDC__ conditionals.
	(scm_boot_guile): Add declaration.
	* init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
	Remove __STDC__ conditionals around function definitions; the
	declarations in init.h will provide the same information, more
	usefully.

	* __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
	complain about it in the error message; the error message is
	adequate without that note, and there's nothing the user can do
	about it.

Wed Aug  7 14:14:46 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* Makefile.in (ancillary): Drop def.sed.

	* posix.c (scm_init_posix): Use numeric values, rather than
	CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
	F_OK.  The symbols aren't available on some systems, and I'm
	pretty sure their values are fixed by common widespread practice.
	* ioext.c (scm_init_ioext): Code here defined them too; remove it.

	More functions unavailable on some systems.
	* configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
	tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
	check for.
	* configure, scmconfig.h.in: Updated, using autoconf and autoheader.
	* posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
	scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
	bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
	stub that signals an error as the #else.

	* Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.

Wed Aug  7 06:28:42 1996  Gary Houston  <ghouston@actrix.gen.nz>

	* unif.c: include ramap.h.

	* read.c (endif): case_insensative_p renamed case_insensitive_p.

	* ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.

	* ports.c: include sys/ioctl.h.

	* scmconfig.h.in: add HAVE_SYS_IOCTL_H.

	* configure.in: check for sys/ioctl.h.

	* ports.c: include <malloc.h> not "malloc.h".

	* mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.

	* fports.c: remove ttyname and tmpnam declarations.

	* posix.c: fewer ttyname declarations.

	* fports.c: include <string.h> not "string.h".

	* init.c, ioext.c: include string.h and unistd.h.

	* gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.

	* async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
	genio.c, simpos.c, vports.c: include string.h.

	* socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.

	* fdsocket.c (getsockopt, setsockopt): change type of optlen from 
	scm_sizet to int.
	(scm_addr_buffer_size): change type from scm_sizet to int.
	(accept, getsockname, getpeername, recvfrom): change type of tmp_size
	from scm_sizet to int.

	* error.c: include unistd.h.

	* __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
	defined.

	* Makefile.in: remove references to .hd, .cd suffix and __scm.hd.

	* __scm.hd, def.sed: deleted.

Tue Aug  6 14:49:08 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	Changes for NeXT, suggested by Robert Brown.
	* configure.in: Call AC_TYPE_MODE_T.
 	(AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
 	NeXT.  Put header file list in alphabetical order.
	* configure, scmconfig.h.in: Regenerated.
	* filesys.c [HAVE_LIBC_H]: #include <libc.h>.

	* filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
	for strerror.
	
	* acconfig.h: New file, providing documentation for the CPP
	symbols defined in configure.in
	* acconfig-1.5.h: Removed; superceded by the above.

Sat Aug  3 01:27:14 1996  Gary Houston  <ghouston@actrix.gen.nz>

	* ioext.c (scm_sys_fdopen): fix the port-table assignment.

*	* fports.c (scm_open_file): don't return #f, throw error.

*	* ioext.c (fileno): renamed from %fileno.
	(soft-fileno): deleted.

	* ports.c (scm_port_revealed): don't need to check for -1 from
	scm_revealed_count.
	(scm_set_port_revealed_x): return unspecified, not #f.

*	* ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.

	* fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.

	* scmconfig.h.in: add HAVE_STRUCT_LINGER.

	* configure.in: check for struct linger, set HAVE_STRUCT_LINGER.

Thu Aug  1 02:58:39 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
	This is necessary on Ultrix, and doesn't hurt portability. 

	* Makefile.in (dist-dir): New target, implementing a new dist system.
	(installed_h_files): Put in alphabetical order.
	Remove duplicate entries for markers.h and unif.h.
	(c_files): Remove duplicate entries for markers.c.
	(ancillary): Renamed from anillery; all uses changed.  Remove
 	PLUGIN; it's a directory, and needs special treatment in dist-dir.
  	Remove all the ../doc/* files; doc/Makefile.in handles that.

	* Makefile.in (libobjs): Remove duplicate entry for markers.o.

	* Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
	every if must have an else, or else the whole command has a
	non-zero exit code whenever the if's condition is false.

Thu Aug  1 08:22:24 1996  Gary Houston  <ghouston@actrix.gen.nz>

	* posix.c: include string.h.

Wed Jul 31 23:43:05 1996  Gary Houston  <ghouston@actrix.gen.nz>

*	* numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
	have been once.

*	* posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
	Remove leading % from scheme names.
	Do not return error values, call SCM_SYSERROR or similar.

	* __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.

Wed Jun 12 00:28:31 1996  Tom Lord  <lord@beehive>

	* struct.c (scm_init_struct): new file.

Fri Jun  7 14:02:00 1996  Tom Lord  <lord@beehive>

	* list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
	(scm_list_head): added list-head for rapidly chopping argument
	lists off of longer lists (and similar).

Tue Jun  4 09:40:33 1996  Tom Lord  <lord@beehive>

	* objprop.c (scm_object_property): assq the cdr of the whash
	handle for obj, not the handle itself.

Mon Jun  3 17:19:30 1996  Tom Lord  <lord@beehive>

	* gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
	weak hash tables last of all marking to avoid an obscure gc bug.
	WARNING: circular lists stored in a weak hash table will hose us.

Fri May 24 09:53:39 1996  Tom Lord  <lord@beehive>

	* vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
	new functions similar to scm_substring_move_left_x and
	scm_substring_move_right_x.

Wed May 22 20:07:01 1996  Tom Lord  <lord@beehive>

	* init.c (scm_boot_guile): prevent gc with scm_block_gc not
	scm_gc_heap_lock!

Thu May  9 09:33:17 1996  Tom Lord  <lord@beehive>

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

	* guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
		removed to a separate library

	* init.c (scm_boot_guile): copied from guile-tcl.c.
	Initialization specific to tcl interpreters removed.

Wed May  8 15:07:37 1996  Tom Lord  <lord@beehive>

	* ports.c (scm_ports_prehistory): size malloced here doesn't
	matter so long as it is non-0 (got rid of "* 4").

Tue May  7 11:43:37 1996  Tom Lord  <lord@beehive>

	* gscm.h: gscm_mkarray eliminated (presumably was not being used
	since its definition was bogus).

Mon May  6 13:02:56 1996  Tom Lord  <lord@beehive>

	* mallocs.[ch]: back again (for rx at least).

Wed Apr 17 08:54:20 1996  Tom Lord  <lord@beehive>

	* ports.c: removed functions relating to the mapping between ports
        and descriptors.   (That stuff is unix-specific and should be collected
	in a separate library).

	* ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
	(Tom Mckay@avanticorp.com)

Mon Apr 15 14:16:55 1996  Tom Lord  <lord@beehive>

	* gc.c (scm_gc_sweep): Immediates in weak vectors were not
	handled correctly (SCM_FREEP was applied to them) -- test for
	NIMP.  Keys in weak hash tables were spuriously (though harmlessly)
	being overwritten with #f.   (brown@grettir.bibliotech.com)

Tue Apr  2 22:25:00 1996  Tom Lord  <lord@beehive>

	* gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
	for a specific symbol or for all symbols.

Mon Apr  1 10:34:55 1996  Tom Lord  <lord@beehive>

	* gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
	keys and weak values confused).

Thu Mar 14 22:20:20 1996  Tom Lord  <lord@beehive>

	* list.c (scm_last_pair): map '()=>'()

Wed Mar 13 16:43:34 1996  Tom Lord  <lord@beehive>

	* pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:

Fri Mar  1 10:39:52 1996  Tom Lord  <lord@beehive>

	* genio.c (scm_getc): 
	NOTE: fgetc may not be interruptable.

	* ports.c (scm_remove_from_port_table): adjust scm_mallocated
	after freeing part of the port table.

Thu Feb 29 16:21:17 1996  Tom Lord  <lord@beehive>

	* strports.c (scm_mkstrport): 
	* vports.c (scm_make_soft_port): allocate a port table entry 
	(possibly triggering gc) before setting the tag of the corresponding
	ports handle.

	* pairs.c (scm_delq_x): never throw an error.

	* vectors.c (scm_make_vector): made the default vector fill argument
	into '() (much more useful than the previous value, "#unspecified")

Mon Feb 26 17:19:09 1996  Tom Lord  <lord@beehive>

	* ports.c (scm_add_to_port_table): Added fields
	to port table entries: file_name, line_num, col.
	Update these in open_file, gen_getc and gen_ungetc.
	Added procedures to access those fields.

Sun Feb 25 00:10:36 1996  Tom Lord  <lord@beehive>

	* procs.c (scm_make_subr_opt): new entry point for making
	anonymous subrs.

Sat Feb 24 17:11:31 1996  Tom Lord  <lord@beehive>

	* gc.h: SCM_STACK_GROWS_UP is now set by autoconf.

Fri Feb 23 10:26:29 1996  Tom Lord  <lord@beehive>

	* numbers.c (scm_exact_p): This function no longer
	implements "integer?".

Thu Feb 22 20:56:16 1996  Tom Lord  <lord@beehive>

	* gc.c (scm_gc_end): simulate a signal at the end of each GC.
	(scm_gc_stats): return an assoc of useful data.  Replaces "room"
	and the stats reporting formerlly built into repl.

	* repl.[ch]: removed.  
	GC statistics keeping moved to gc.c.
	Other statistics keeping can be done from Scheme.
	REPLS are now written in Scheme.

Wed Feb 21 10:28:53 1996  Tom Lord  <lord@beehive>

	* cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
	conservatively marked objects).

	* throw.c (scm_ithrow): Unwind up to the right catch during a throw!

	* error.c (scm_init_error): init system_error_sym here, not in repl.c.

	* feature.c (scm_compiled_library_path): moved here from repl.c.
	This file is for stuff relating specifically to Scheme libraries
	like slib.

	* eval.c (scm_m_define): don't give warning about redefinition, don't
	check verbosity.  

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

	* repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

	* error.c: scm_warn eliminated.

	* read.c (scm_lreadr): extra right paren gets an error, not a warning.

	* repl.c, marksweep.c, gc.c (various): 
	lose exit_report, growth_mon.

	* gscm.c: got rid of verbosity functions.

Tue Feb 20 00:19:10 1996  Tom Lord  <lord@beehive>

	between the call to procedurep and use.

	* error.c (scm_everr): 
	* gc.c (fixconfig): 
	* gsubr.c (scm_make_gsubr): use exit, not scm_quit.  still wrong, 
	but less so.

	* strports.c: don't reveal the port's string to the caller
	because it changes size.

	(stputc stwrite): check/change the strings length with interrupts
	blocked.

	* objprop.c (scm_set_object_property_x &c): use the generic
