[bpt/guile.git] / libguile / ChangeLog

Thu May 15 16:22:33 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* 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.

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

 	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>

 	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.
