[bpt/guile.git] / libguile / ChangeLog

2001-03-14  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs),
	(gh_scm2floats, gh_scm2doubles): Check for malloc() returning NULL
	in various places.
	(gh_scm2newstr, gh_symbol2newstr): Change call to
	scm_must_malloc() to malloc(), because user-free()able memory is
	allocated.

	* gc.c: Added declaration of `scm_debug_check_freelist'.

2001-03-13  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	misc-errors.

	* macros.h (SCM_ASSYNT):  On assertion failure, issue a misc-error

2001-03-08  Neil Jerram  <neil@ossau.uklinux.net>

2001-03-08  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

	* ramap.c (racp): Removed optimization which caused array copying
	to fail if the two arrays shared storage.  Re-inserted the IVDEP
	macros removed in the change of 2000-03-09.  (Don't really have a
	complete grasp of what they are for, but they seem to be necessary
	on Crays.  This needs testing!)  Thanks to Miroslav Silovic.

	* hash.c (scm_string_hash): Don't downcase characters.

2001-03-07  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

	(*.doc): Add dependency on guile-snarf.awk.in.

	* guile-snarf.awk.in: Neglect spaces at the end of

	middle of docstrings.  (To avoid the problem with gcc-2.96.)

2001-03-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* coop-threads.c (scm_call_with_new_thread), load.c
	(scm_primitive_load, scm_sys_search_load_path), random.c
	(scm_c_default_rstate), struct.c (scm_make_struct_layout,

	(potentially) issue a scm-misc-error or wrong-num-args error
	message.

	* load.c (scm_search_path):  Use SCM_ASSERT_TYPE to give details
	about the expected type with the wrong-type-arg error message.

	* smob.c (scm_make_smob):  Abort on misuse of smob - it indicates
	a C level bug that can't be fixed from scheme anyway.

2001-03-05  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

	* eval.c (scm_m_letstar): Removed check for duplicate bindings.
	Duplicate bindings are OK in a let* since a let* is semantically
	equivalent to a nested set of let:s.

2001-03-05  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* print.c (scm_print_options): Fixed texinfo in docstring.

	* net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if

	* socket.c (scm_fill_sockaddr): don't allow buffer overflows when
	taking an unexpectedly large filename for an AF_UNIX socket from
	bind/connect/sendto (thanks to Martin Grabmueller).
	
	* socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
	former and adjusted the latter.
	(scm_socket, scm_socketpair): cosmetic changes.
	(scm_getsockopt, scm_setsockopt): declare optlen as int, not
	size_t as socklen_t substitute.  don't restrict args/return values
	to INUM: allow full range of int or size_t.
	(scm_fill_sockaddr): check arguments before allocating memory, to
	avoid leakage.  use malloc, not scm_must_malloc.
	(scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
	substitute.  free the sockaddr structure before throwing an error.
	(scm_init_add_buffer): procedure removed, together with its static
	buffer scm_addr_buffer, which wouldn't be thread safe.  instead,
	define a macro MAX_ADDR_SIZE and declare the buffer where needed.
	(scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
	scm_sendto): use a local buffer instead of scm_addr_buffer.
	adjust for new SCM_SOCK_FD_TO_PORT.  use int for address size,
	not size_t.
	(scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
	call to detect whether recvfrom could be bothered to set the address.
	(scm_init_socket): don't call scm_init_addr_buffer.

2001-03-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	scm_transpose_array, scm_enclose_array, scm_array_in_bounds_p,
	scm_uniform_vector_ref, scm_array_set_x, scm_uniform_array_read_x,
	scm_uniform_array_write, scm_bit_set_star_x, scm_bit_count_star,
	scm_array_to_list, scm_array_prototype), validate.h
	(SCM_VALIDATE_NUMBER_COPY):  Don't call function scm_wta, call
	scm_misc_error or scm_wrong_type_arg instead.

	* validate.h (SCM_WTA, RETURN_SCM_WTA):  Deprecated.

2001-03-04  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

	* goops.c, goops.h (scm_sys_pre_expand_closure_x): Removed.

	script_get_backslash, script_read_arg), unif.c (scm_cvref):  Don't
	call function scm_wta, call scm_misc_error or scm_wrong_type_arg
	instead.

	check for empty combinations; use SCM_EVALIM2 for the same reason
	in the non-toplevel loop.
	(nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
	New labels with the meaning of their non-"nontoplevel" partners,
	but they are used when it is known that the body is not evaluated at
	top-level.
	(scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
	reporting for empty combinations.

	* eval.c (scm_ceval, scm_deval): When evaluating expressions on
	top level, create a fresh top-level environment for each
	expression instead of mutating the exisint frame.  This is

2001-02-15  Marius Vollmer  <mvo@zagadka.ping.de>

	* symbols.c (scm_mem2symbol): Put a empty statement after the
	next_symbol label.  This is mandated by ANSI, appearantly.

2001-02-13  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* gc_os_dep.c: Do not include <linux/version.h>.  It makes no
	sense to compile for a specific kernel version.  Do not include
	<asm/signal.h> while defining __KERNEL__.  This hack should no
	longer be needed and caused problems.

2001-02-13  Marius Vollmer  <mvo@zagadka.ping.de>

	* eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of
	SCM_CEVAL when evaluating subforms of `begin' forms.  SCM_CEVAL
	can not deal with immediates.

2001-02-12  Keisuke Nishida  <kxn30@po.cwru.edu>

	* list.c (scm_list_copy): Validate the first argument.

2001-02-11  Marius Vollmer  <mvo@zagadka.ping.de>

	evaluated with respect to the module system.
	
	* modules.h. modules.c (scm_current_module_lookup_closure): New
	function.

	* eval.h (scm_primitive_eval, scm_primitive_eval_x): New
	prototypes.
	(scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
	names to better reflect their meaning.

	* eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
	evaluated at top-level and synronize lookup closure before
	executing every subform.
	(scm_primitve_eval_x, scm_primitive_eval): New functions.
	(scm_eval_x, scm_eval): Reimplement in terms of
	scm_primitive_eval_x and scm_primitive_eval, respectively.
	
2001-02-09  Marius Vollmer  <mvo@zagadka.ping.de>

	* macros.c (scm_macro_name, scm_macro_transformer): Use
	SCM_SMOB_DATA instead of SCM_CDR.  Provided by Martin Grabmueller.

	and C names.
	(scm_select_module, scm_set_current_module): Likewise.  Changed
	all uses.
	
	* ports.c (scm_port_for_each): Make a snapshot of the port table
	before iterating over it.  The table might change while the user
	code is running.  With the snapshot, the user can depend on the
	fact that each port that existed at the start of the iteration is
	encountered exactly once.  (ice-9 popen) depends on this.

2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* strings.h (SCM_STRING_MAX_LENGTH):  New macro.

	* strings.c (scm_makstr, scm_take_str, scm_make_string):  Added
