  72
  73         * gh.h/gh_data.c (gh_ints2scm):  Changed the signature to use a

  82         (gh_scm2newstr, gh_symbol2newstr): Change call to
  83         scm_must_malloc() to malloc(), because user-free()able memory is
  84         allocated.
  85
  86         * gc.c: Added declaration of `scm_debug_check_freelist'.
  87

 103         scm_m_atdispatch):  Provide definitions for FUNC_NAME.  Don't use
 104         SCM_ASSYNT to check for correct argument types.  Either use some
 105         SCM_VALIDATE_* macro or an explicit test.
 106
 107         (scm_make_foreign_object):  Don't use SCM_ASSERT to check for
 108         misc-errors.
 109

 160         the file.
 161
 162 2001-03-09  Keisuke Nishida  <kxn30@po.cwru.edu>

 204
 205         * ramap.c (racp): Removed optimization which caused array copying
 206         to fail if the two arrays shared storage.  Re-inserted the IVDEP
 207         macros removed in the change of 2000-03-09.  (Don't really have a
 208         complete grasp of what they are for, but they seem to be necessary
 209         on Crays.  This needs testing!)  Thanks to Miroslav Silovic.
 210
 211         * hash.c (scm_string_hash): Don't downcase characters.
 212
 213 2001-03-07  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

 224
 225 2001-03-07  Keisuke Nishida  <kxn30@po.cwru.edu>
 226
 227         * Makefile.am (*.x): Add dependency on snarf.h and guile-doc-snarf.in.

 231         SCM_SNARF_DOCSTRING_END.  Skip lines "# NN ..." in the
 232         middle of docstrings.  (To avoid the problem with gcc-2.96.)
 233
 234 2001-03-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 235

 242
 243         * load.c (scm_search_path):  Use SCM_ASSERT_TYPE to give details
 244         about the expected type with the wrong-type-arg error message.
 245
 246         * smob.c (scm_make_smob):  Abort on misuse of smob - it indicates
 247         a C level bug that can't be fixed from scheme anyway.
 248
 249 2001-03-05  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
 250
 251         * eval.c (scm_m_letstar): Removed check for duplicate bindings.
 252         Duplicate bindings are OK in a let* since a let* is semantically
 253         equivalent to a nested set of let:s.
 254
 255 2001-03-05  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

 261         return NULL instead of signalling an error.
 262
 263 2001-03-04  Gary Houston  <ghouston@arglist.com>
 264
 265         * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
 266         taking an unexpectedly large filename for an AF_UNIX socket from
 267         bind/connect/sendto (thanks to Martin Grabmueller).
 268
 269         * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
 270         former and adjusted the latter.
 271         (scm_socket, scm_socketpair): cosmetic changes.
 272         (scm_getsockopt, scm_setsockopt): declare optlen as int, not
 273         size_t as socklen_t substitute.  don't restrict args/return values
 274         to INUM: allow full range of int or size_t.
 275         (scm_fill_sockaddr): check arguments before allocating memory, to
 276         avoid leakage.  use malloc, not scm_must_malloc.
 277         (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
 278         substitute.  free the sockaddr structure before throwing an error.
 279         (scm_init_add_buffer): procedure removed, together with its static
 280         buffer scm_addr_buffer, which wouldn't be thread safe.  instead,
 281         define a macro MAX_ADDR_SIZE and declare the buffer where needed.
 282         (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
 283         scm_sendto): use a local buffer instead of scm_addr_buffer.
 284         adjust for new SCM_SOCK_FD_TO_PORT.  use int for address size,
 285         not size_t.
 286         (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
 287         call to detect whether recvfrom could be bothered to set the address.
 288         (scm_init_socket): don't call scm_init_addr_buffer.
 289
 290 2001-03-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

 301         scm_array_to_list, scm_array_prototype), validate.h
 302         (SCM_VALIDATE_NUMBER_COPY):  Don't call function scm_wta, call
 303         scm_misc_error or scm_wrong_type_arg instead.
 304
 305         * validate.h (SCM_WTA, RETURN_SCM_WTA):  Deprecated.

 340         (scm_m_lambda): Check for duplicate arguments.
 341         (scm_ceval, scm_deval): When executing a body: only cons a new
 342         toplevel environment frame when it is different from the
 343         existing one; use EVALCAR instead of SIDEVAL so that we can properly
 344         check for empty combinations; use SCM_EVALIM2 for the same reason
 345         in the non-toplevel loop.
 346         (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
 347         New labels with the meaning of their non-"nontoplevel" partners,
 348         but they are used when it is known that the body is not evaluated at
 349         top-level.
 350         (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
 351         reporting for empty combinations.
 352
 353 2001-03-02  Keisuke Nishida  <kxn30@po.cwru.edu>

 377         (scm_symbol_to_string, scm_string_to_symbol): Changed use of @t{}

 380
 381         * strports.c (scm_eval_string): Cleaned up the docstring.
 382
 383         * struct.c (scm_struct_p, scm_struct_vtable_p): Added texinfo

 403 2001-02-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 404
 405         * __scm.h (SCM_ASSERT_TYPE):  Add missing macro parameter.
 406         (Obviously nobody compiles with SCM_RECKLESS defined...)
 407
 408         * validate.h (SCM_ASSERT_RANGE):  Use the argument number.

 418         * numbers.c (scm_two_doubles, scm_sys_expt, scm_sys_atan2,
 419         scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
 420         since use of `z' suggests that the arguments may be complex.
 421
 422         * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring
 423         typos.

 438         (make_class_from_template): Do not bother to set the current
 439         module around the call to DEFVAR, scm_eval takes care of that.
 440         (scm_init_goops): Make scm_module_goops and
 441         scm_goops_lookup_closure permanent objects.
 442
 443         * eval.c (scm_ceval, scm_deval): When evaluating expressions on
 444         top level, create a fresh top-level environment for each
 445         expression instead of mutating the exisint frame.  This is
 446         important when that frame is closed over.
 447
 448         * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
 449         SCM_DIGSPERLONG instead of DIGSPERLONG.
 450
 451 2001-02-21  Marius Vollmer  <mvo@zagadka.ping.de>
 452
 453         * eval.c (scm_ceval, scm_deval): Check for wrong number of args
 454         before applying arrow procedure in `cond' and before applying
 455         receiver procedure in call-with-current-continuation.
 456         (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
 457         macro.  The argument is expanded more than one time.
 458
 459         * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
 460         SCM_BIGDIG instead of BIGDIG.  Thanks to Steven G. Johnson!

 652         fact that each port that existed at the start of the iteration is
 653         encountered exactly once.  (ice-9 popen) depends on this.

 979         from Matthias Köppe:
 980
 981         * objects.h (SCM_SET_ENTITY_SETTER): new macro.  SCM_ENTITY_SETTER
 982         casts its result, so doesn't yield an lvalue per ANSI C.
 983
 984         * goops.c (s_scm_sys_set_object_setter_x): use
 985         SCM_SET_ENTITY_SETTER.
 986         (clear_method_cache): use SCM_SET_ENTITY_PROCEDURE.
 987
 988         * gc.h (SCM_GC_SET_CARD_BVEC): new macro.  SCM_GC_CARD_BVEC casts
 989         its result, so doesn't yield an lvalue per ANSI C.
 990         (SCM_GC_SET_CARD_FLAGS): ditto for SCM_GC_GET_CARD_FLAGS.
 991         (SCM_GC_CLR_CARD_FLAGS): redefined in terms of
 992         SCM_GC_SET_CARD_FLAGS.
 993         (SCM_GC_SET_CARD_FLAG, SCM_GC_CLR_CARD_FLAGS): ditto.
 994
 995         * gc.c (INIT_CARD): use the explicit setter macro to set the bvec.
 996
 997 2001-01-08  Gary Houston  <ghouston@arglist.com>
 998
 999         * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): new macro.
1000         * ioext.c (scm_read_string_x_partial, scm_read_delimited_x),
1001         socket.c (scm_recvfrom): use the new macro, plus minor docstring
1002         changes.
1003         * ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
1004         for fdes.  if current input port is used, check that it's a file
1005         port.
1006
1007 2001-01-06  Gary Houston  <ghouston@arglist.com>
1008
1009         * ioext.c (scm_read_string_x_partial): new procedure, implements
1010         read-string!/partial.
1011         * ports.c (scm_take_from_input_buffers): new procedure used by
1012         scm_read_string_x_partial.
1013         (scm_drain_input): use scm_take_from_input_buffers.
1014
1015 2001-01-06  Marius Vollmer  <mvo@zagadka.ping.de>
1016
1017         * validate.h (SCM_VALIDATE_NUMBER): New.
1018
1019 2001-01-03  Michael Livshin  <mlivshin@bigfoot.com>
1020
1021         * guardians.c (F_GREEDY, F_LISTED, F_DESTROYED, GREEDY_P,
1022         SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
1023         SET_DESTROYED): new defines/macros.
1024         (GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
1025         (add_to_live_list): takes a `guardian_t *' now, not SCM.
1026         (guardian_print): print more info.
1027         (guardian_apply): check if the guardian is destroyed, and throw an
1028         error if so.  take one more optional argument `throw_p'.
1029         (scm_guard): depending on the value of `throw_p', return a boolean
1030         result.
1031         (scm_get_one_zombie): remove redundant property test.
1032         (guardian_t): represent the various (currently 3, I hope nothing
1033         more gets added) boolean fields as bit flags.
1034         (scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
1035         (scm_destroy_guardian_x): new procedure.
1036
1037         * guardians.h: added prototypes for `scm_guardian_greedy_p' and
1038         `scm_guardian_destroyed_p'.  changed prototype for `scm_guard'.
1039
1040 2001-01-01  Gary Houston  <ghouston@arglist.com>
1041
1042         * fports.c (fport_write): bugfix: handle short writes for
1043         unbuffered ports too.  optimize the buffered case by minimizing
1044         the number of write/flush calls.
1045         (write_all): new helper procedure.
