[bpt/guile.git] / libguile / ChangeLog

Thu May 29 02:47:36 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* regex-posix.c (scm_init_regex_posix): Register the "regex"
	feature, to help boot-9.scm decide whether to import the regex
	module. 

Thu May 29 02:19:40 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* eval.c: Include scmconfig.h at the beginning of the file so that
 	HAVE_ALLOCA_H may properly be defined.  Thanks to Bill Janssen for
 	pointing this out.

	* regex-posix.c: #include "_scm.h" before conditionally #including
	<regex.h>; the former defines HAVE_REGCOMP.

	* regex-posix.c: #include <regex.h> conditionally, so the file is
	CPP'able (for dependency scanning) even on systems that don't have
	a <regex.h> header.

Tue May 27 23:48:38 1997  Jim Blandy  <jimb@floss.cyclic.com>

	Add new R4RS-compliant syntax for keywords.
	* read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
	regardless of the setting of the `keywords' read option.
	* kw.c (prin_kw): Print keywords using the `#:' syntax, so they
	can be re-read no matter what the setting of the `keywords' read
	option.

Tue May 27 22:47:31 1997  Tim Pierce  <twp@twp.tezcat.com>

	Add support for POSIX regular expressions.
	
	* regex-posix.c, regex-posix.h: New files. (Some code
	is taken liberally from rx/rgx.c in the old Guile dist.)

	* init.c: Include regex-posix.h.
	(scm_boot_guile_1): Call scm_init_regex_posix.
	
	* Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
	Add regex-posix.[ch] sources.
	* Makefile.in: Regenerated.
	
	* scmconfig.h.in: Add HAVE_REGCOMP macro.  (automake is supposed
	to do this automatically?  It didn't for me, bleh.)
	
Mon May 26 18:51:29 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* fports.c (print_pipe_port): New function.
	(scm_fptob): Use print_pipe_port instead of scm_prinport; the
	latter doesn't even take the right arguments.

	* Makefile.am: Increment shared lib revision number.  I think
	sometimes the uninstalled Guile finds the installed shared lib;
	Gord says doing this might help.  As things turned out, I can't
	say whether it does.
	* Makefile.in: Regenerated.

	* gh_init.c (gh_enter): Cast c_main_prog to a void * before
 	passing it as the closure argument to scm_boot_guile.  (Bill
 	Janssen)
	
	* ports.c (print_void_port, putc_void_port, puts_void_port,
	write_void_port, flush_void_port, getc_void_port, close_void_port,
	noop0): Use ANSI prototypes instead of K&R declarations, so the
	initialization of void_port_ptob gets aggressively type-checked.
	Fix arguments of print_void_port and write_void_port.  (Bill
	Janssen)

	* COPYING, __scm.h, _scm.h, alist.c, alist.h, append.c, append.h,

 	address for FSF.

Mon May 26 12:37:30 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* script.c (scm_find_executable): Use prototype-style definition
 	here; apparently it's not quite right to have const in a prototype
 	and then use a K&R declaration.  I wonder if stuff like this will
 	go away if we compile with -Wrequire-prototypes, or whatever that
 	is...  (Bernard URBAN)

	* scmhob.h: New text from Bernard URBAN.

Sat May 17 17:14:36 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* script.c: Don't #define const on hpux.  Configure takes care of
	this.  (Thanks to Larry Schwimmer.)

	* script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
	decide whether to #include <unistd.h>, instead of listing a bunch
	of systems.  Don't #include stdio twice.  Removed dyked-out
	definition of scm_find_impl_file.

Fri May 16 03:06:08 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
	library version info to 1:0.
	* Makefile.in: Regenerated.

	* backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
 	gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
 	gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,

 	script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
 	throw.c: Update copyright years; these files have been worked on
	significantly in 1997, but only had copyright years for 1996.
	Also, change name of copyright holder on some from Mikael
	Djurfeldt to Free Software Foundation; he has signed papers
	assigning the changes to the FSF.
	
	* script.c (scm_shell_usage): Pass FATAL to exit.  There's no
	reason not to give the user the option.

	* net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
	Return #f on end-of-file when scanning table (i.e. when called
	with no arguments).  Try to catch errors, when we can.
	* posix.c (scm_getgrgid, scm_getpwuid): Same.
	
	* script.h (scm_shell_usage, scm_compile_shell_switches): New
	external declarations.  These are useful.

Thu May 15 05:21:36 1997  Gary Houston  <ghouston@actrix.gen.nz>

	* posix.c: don't include <sys/select.h> or define macros for
	select, since they were not used in this file.

	* filesys.c (scm_select): make the fifth parameter microseconds,
	not milliseconds.  let the fourth parameter be either a real value
	or an integer or #f.  The first, second and third arguments can
	now be vectors: the type of the corresponding return set will be
	the same.
	(set_element, get_element): new static procedures.

Wed May 14 12:18:12 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* strports.c (scm_eval_string): New function.
	(scm_eval_0str): Trivially re-implemented in terms of
	scm_eval_string.
	* strports.h (scm_eval_string): New extern decl.

	* net_db.c (h_errno): Add extern decl for this.

	* fports.c (local_pclose): New function.
	(scm_pipob): Use it in the initializer here.

	From Tim Pierce:
	* net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
	Use a meaningful error message when signalling an error.  For
	this, scm_gethost must check h_errno rather than errno.

Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* Makefile.in: Regenerated, using automake-1.1p.

Tue May 13 04:34:52 1997  Gary Houston  <ghouston@actrix.gen.nz>

	* socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
	not SCM_UNSPECIFIED.

	* script.c (scm_compile_shell_switches): don't append (quit) if
	interactive.
	(scm_shell): call scm_exit_status and exit on the result of the
	evaluation.

Mon May 12 17:23:58 1997  Jim Blandy  <jimb@floss.cyclic.com>

	Ensure that shared substrings are handled properly when passed to
	a system call or other foreign function.  Many thanks to Tim
	Pierce!
	* symbols.h (SCM_COERCE_SUBSTR): new macro.
	* filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
 	scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
 	scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
 	scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
 	scm_strftime), vports.c (scm_make_soft_port), backtrace.c
 	(scm_display_error_message): use RO macros when strings may be RO.
	* error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
 	scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
 	scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
 	(scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
 	(scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
 	(scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
 	scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
 	scm_strftime), vports.c (scm_make_soft_port): use
 	SCM_COERCE_SUBSTR to make sure shared substrings are
 	null-terminated.

Mon May 12 15:33:10 1997  Jim Blandy  <jimb@totoro.cyclic.com>

	* error.c (scm_error): Add newline to error message.

	* init.c (scm_init_standard_ports): Doc fix.

Thu May  8 14:38:01 1997  Marius Vollmer  <mvo@zagadka.ping.de>

	* dynl-shl.c: Completely replaced with new code from Bernard
 	URBAN.

	* script.c (scm_ice_9_already_loaded): New variable.
	(scm_compile_shell_switches): Use it.

Mon May  5 20:35:08 1997  Gary Houston  <ghouston@actrix.gen.nz>

	* filesys.c (scm_input_waiting_p): add missing third argument to
	scm_misc_error.

	* stime.c (scm_localtime): copy the result of localtime before
	calling gmtime in case they share a buffer.
	(scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
	nor HAVE_TZNAME.

Fri May  2 19:07:11 1997  Gary Houston  <ghouston@actrix.gen.nz>

	* eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
	
Thu May  1 17:01:45 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* Makefile.am (check-local): New target, which causes 'make check'
 	to run gh_test_c and gh_test_repl, with some trivial input.
	* Makefile.in: Rgnrtd.

Tue Apr 29 19:00:40 1997  Marius Vollmer  <mvo@zagadka.ping.de>

	* dynl.c (print_dynl_obj): Indicate whether the dynamic object has
 	been unlinked.

Mon Apr 28 06:10:14 1997  Gary Houston  <ghouston@actrix.gen.nz>

	* async.c (scm_sys_tick_async_thunk): commented out.  I'm not
	sure how this was supposed to work.
	(scm_async_click): don't send SCM_TICK_SIGNAL.
	(scm_init_async): don't initialize %tick-thunk.

	* the following change doesn't affect the Scheme interface:
 	gc-thunk is called at the end of garbage collection.  however it's
 	no longer implemented by pretending it's a signal.
	
	* gc.c (scm_gc_end): don't call scm_take_signal.  instead mark the
	system async corresponding to scm_gc_thunk.
	* async.h: declare scm_gc_async.
	* async.c (scm_sys_gc_async_thunk): apply the thunk named by
	gc-thunk directly, instead of going through a signal handler.
	(scm_gc_async): new variable, points to the GC system-async.
	(scm_init_async): save the GC async as scm_gc_async instead
	of using system_signal_asyncs.
	(scm_gc_vcell): new variable, stores the gc-thunk vcell.

Mon Apr 28 19:14:44 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
	Don't screw up if we're interrupted.
	* Makefile.in: Regeneradet.

Sun Apr 27 17:57:15 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* aclocal.m4: Removed; unnecessary, given changes of Apr 24.

	* Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
	we're not using AM_INIT_GUILE_MODULE any more.
	* Makefile.in: Reneregated.

Thu Apr 24 00:41:08 1997  Jim Blandy  <jimb@floss.cyclic.com>
