[bpt/guile.git] / libguile / ChangeLog

1998-05-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* readline.c (rl_cleanup_after_signals, rl_free_line_state): New
	readline functions to come in release 2.3.  (Thanks to Chet
	Ramey.)
	(handle_errors): Use the above functions.

1998-05-12  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* readline.c: Improvements for readline support: Handle errors
	better; Implement before-read-hook.

1998-05-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* init.c (scm_boot_guile_1), readline.c: Test for
	HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE.  (Need to
	assure that we have version >= 2.1.)

1998-05-11  Mikael Djurfeldt  <mdj@kenneth>

	* readline.c (scm_add_history): Bugfix: Do strdup before giving
	away the string to add_history.
	(completion_function): Do completion for readline. (Thanks to
	Andrew Archibald.)
	(scm_filename_completion_function): New procedure: Filename
	completer.
	(current_input_getc): New function.  Use this one instead of
	standard getc from readline.

	* throw.c, throw.h (scm_handle_by_throw): New function: This
	handler throws errors to next handler on the dynwind chain.

1998-05-09  Mikael Djurfeldt  <mdj@kenneth>

	* scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
	used.

1998-05-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* procprop.c (scm_i_procedure_arity): New function.  Returns arity
	of procedure.
	(scm_procedure_properties): Modified to return arity together with
	other properties.
	(scm_procedure_property): Added the read-only property `arity'.
	(scm_set_procedure_property_x): It is an error to set the `arity'
	property.

	* gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
	prefix SCM_; Made f_gsubr_apply global and added prefix scm_.

	* procprop.h (scm_sym_arity): New symbol.

	* objects.c (scm_set_object_procedure_x): New procedure: Use this
	to set the dispatch procedure of an operator or entity object.

	* objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
	Made procedure slots read-only.

	* eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
	scm_tcs_cons_gloc case in zero args switch; Fixed args
	construction for operators in scm_tcs_cons_gloc case in two args
	switch.

1998-05-02  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* fluids.c: Removed use of assert.h (in order to avoid
	__eprintf).

	* Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.

	* dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.

	* eval.c (SCM_CEVAL): Do more thorough argument checking.  This
	change makes the evaluator safer at the cost of evaluation speed.
	It handles the case when the user has added a non-immediate
	improper end of the application form, e.g., `(+ 0 . x)'.
	(Earlier only cases like `(+ 0 . 0)' were handled.)  I've tried to
	minimize the extra cost as much as possible.  The new code is
	enclosed in #ifdef CAUTIOUS regions.  NOTE: This also fixes the
	problem with structs planted directly in the code (e.g. by a
	macro).  This no longer causes segmentation fault.  (Thanks to
	Eric Hanchrow.)
	
	* eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
	arg `proc' in order to be able to throw errors; New argument
	checking code.

	* Removed extra #include "debug.h"

1998-04-25  Mikael Djurfeldt  <mdj@kenneth>

	* scmsigs.c: Declare usleep as returning void on some systems.
	(scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
	Satchell.)

	* coop.c (usleep): Return void on some systems.

1998-04-20  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.

	* coop.c: Changed return type of usleep to int.

	* scmsigs.c (scm_usleep): New procedure; Declare usleep if it
	isn't found in the OS.

	* iselect.h: #define scm_internal_select select if GUILE_ISELECT
	isn't enabled.  (Thought that I had made this change ages ago...)

	* iselect.c: Declare bzero if not defined by OS.

1998-04-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* dynl.c (scm_must_free_argv): Fixed memory leak due to negated
	condition.  (Thanks to John Tobey.)

	* continuations.c (scm_make_cont), debug.c (scm_make_memoized,
	scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
	A section.

	* __scm.h: Start the long-term project of moving to POSIX threads.
	Phase 1: Classification of all critical sections.
	(SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
	for A sections.  (See comments in __scm.h for details.)

	* dynl.c: Only check that HAVE_DLOPEN is defined before loading
	dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.

1998-04-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
	cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
	(libpath.h, versiondat.h): Replaced dependency on Makefile with
	dependencies on $(srcdir)/Makefile.in
	$(top_builddir)/config.status in order to avoid circularity.

	* script.c (scm_compile_shell_switches): Bugfix: Don't discount i
	from argc if argc was 0 initially.

	* Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
	in generation of libpath.h.

1998-04-15  Mikael Djurfeldt  <mdj@nada.kth.se>

	* Makefile.am (libguile_la_LDFLAGS): Bumped version number of
	libguile from 2 to 3.

1998-04-14  Mikael Djurfeldt  <mdj@nada.kth.se>

	* Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.

1998-04-13  Mikael Djurfeldt  <mdj@kenneth>

	* ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
	scm_set_port_column_x, scm_port_filename,
	scm_set_port_filename_x): Removed optional arguments.  Added
	proper argument checking.

	* eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
	stack size in machine words.

	* unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
	rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings.  (Thanks
