[bpt/guile.git] / libguile / ChangeLog

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.)

	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.

	--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.

*	* 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.

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>

	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.

	* 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>

	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.

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>

	* 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!

Wed May 15 16:13:29 1996  Tom Lord  <lord@beehive>

	* ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.

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

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

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

	* 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.

	* 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
	hashing functions and be threadsafe.

	* eval.c (scm_unmemocar): do this operation in a thread-safe way.
	(per suggestion jaffer@gnu.ai.mit.edu).

	* mbstrings.c (scm_multi_byte_string): guard against argument list
	changing length.

	* strings.c (scm_make_string): loop cleanup

	* unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
	a scheme function.

	changing length.

	* variable.c (scm_builtin_variable): check for/make a built-in
	variable automicly.

	* vectors.c (scm_vector): while filling the new array,
	guard against a list of fill elements that grows after

	* hashtab.c -- new file: general hash table
	functions.  hash, hashq, hashv, hashx.

	* tags.h: made wvect an option bit of vector.

Mon Feb 19 09:38:05 1996  Tom Lord  <lord@beehive>

	* symbols.c: made the basic symbol table operations atomic.

	* root.c &c.: collected stack-specific global state.
	linum/colnum etc *should* be port-specific state.

	* struct.c (scm_init_struct): init the first struct type during
	initialization to fix a race condition.

	* continuations.c (scm_dynthrow): pass throwval in the 'regs'
	object, not in a global.
	(suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

	* throw.c (_scm_throw): Pass throwval on the stack, not in a global
	(suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

	* *.[ch]: namespace cleanup.  Changed all (nearly) exported CPP
	and C symbols to begin with SCM_ or scm_.

Sun Feb 18 15:55:38 1996  Tom Lord  <lord@beehive>

	* gsubr.c (scm_gsubr_apply): statically allocate the
	array of arguments (bothner@cygnus.com).

	* async.c: New support for interrupt handlers.

Thu Feb 15 11:39:09 1996  Tom Lord  <lord@beehive>

	* symbols.c (scm_string_to_symbol et al.): number of tweaky changes to 
	set the multi_byte flag correctly in symbols.  This is wrong.
	intern_obbary_soft and msymbolize should take an extra parameter.
	Also, weird multibyte symbols don't print correctly.
	The weird symbol syntax is also a bit bogus (emacs doesn't quite
	cope).

Tue Feb 13 11:39:37 1996  Tom Lord  <lord@beehive>

	* symbols.c (scm_string_to_obarray_symbol): obarray == #f means
	use the system symhash.   == #t means create an uninterned symbol.

Wed Feb  7 09:28:02 1996  Tom Lord  <lord@beehive>

	* strings.c (scm_make_shared_substring): build'em.
	It might better to keep a table of these and use one
	less cons-pair per shared-substring.

Tue Feb  6 17:45:21 1996  Tom Lord  <lord@beehive>

	* strings.c (scm_string_shared_substring): create shared 
	substrings.  (Doesn't handle mb strings yet).
