   6         scm_m_atdispatch):  Provide definitions for FUNC_NAME.  Don't use
   7         SCM_ASSYNT to check for correct argument types.  Either use some
   8         SCM_VALIDATE_* macro or an explicit test.
   9
  10         (scm_make_foreign_object):  Don't use SCM_ASSERT to check for

  64

 102
 103         * ports.c (scm_port_column): Docstring fixes: (i) port-line arg is

 105
 106 2001-03-08  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
 107
 108         * ramap.c (racp): Removed optimization which caused array copying
 109         to fail if the two arrays shared storage.  Re-inserted the IVDEP
 110         macros removed in the change of 2000-03-09.  (Don't really have a
 111         complete grasp of what they are for, but they seem to be necessary
 112         on Crays.  This needs testing!)  Thanks to Miroslav Silovic.
 113
 114         * hash.c (scm_string_hash): Don't downcase characters.
 115
 116 2001-03-07  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

 125
 126         * validate.h: Code formatting.
 127
 128 2001-03-07  Keisuke Nishida  <kxn30@po.cwru.edu>
 129
 130         * Makefile.am (*.x): Add dependency on snarf.h and guile-doc-snarf.in.
 131         (*.doc): Add dependency on guile-snarf.awk.in.
 132
 133         * guile-snarf.awk.in: Neglect spaces at the end of
 134         SCM_SNARF_DOCSTRING_END.  Skip lines "# NN ..." in the
 135         middle of docstrings.  (To avoid the problem with gcc-2.96.)
 136
 137 2001-03-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 138
 139         * coop-threads.c (scm_call_with_new_thread), load.c

 142         scm_struct_ref, scm_struct_set_x):  Don't use SCM_ASSERT to
 143         (potentially) issue a scm-misc-error or wrong-num-args error
 144         message.
 145
 146         * load.c (scm_search_path):  Use SCM_ASSERT_TYPE to give details
 147         about the expected type with the wrong-type-arg error message.
 148
 149         * smob.c (scm_make_smob):  Abort on misuse of smob - it indicates
 150         a C level bug that can't be fixed from scheme anyway.
 151
 152 2001-03-05  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
 153
 154         * eval.c (scm_m_letstar): Removed check for duplicate bindings.
 155         Duplicate bindings are OK in a let* since a let* is semantically
 156         equivalent to a nested set of let:s.
 157
 158 2001-03-05  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>
 159
 160         * print.c (scm_print_options): Fixed texinfo in docstring.
 161
 162         * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
 163         the underlying functions getservent, getprotoent or getnetent
 164         return NULL instead of signalling an error.
 165
 166 2001-03-04  Gary Houston  <ghouston@arglist.com>
 167
 168         * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
 169         taking an unexpectedly large filename for an AF_UNIX socket from
 170         bind/connect/sendto (thanks to Martin Grabmueller).
 171
 172         * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
 173         former and adjusted the latter.
 174         (scm_socket, scm_socketpair): cosmetic changes.
 175         (scm_getsockopt, scm_setsockopt): declare optlen as int, not
 176         size_t as socklen_t substitute.  don't restrict args/return values
 177         to INUM: allow full range of int or size_t.
 178         (scm_fill_sockaddr): check arguments before allocating memory, to
 179         avoid leakage.  use malloc, not scm_must_malloc.
 180         (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
 181         substitute.  free the sockaddr structure before throwing an error.
 182         (scm_init_add_buffer): procedure removed, together with its static
 183         buffer scm_addr_buffer, which wouldn't be thread safe.  instead,
 184         define a macro MAX_ADDR_SIZE and declare the buffer where needed.
 185         (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
 186         scm_sendto): use a local buffer instead of scm_addr_buffer.
 187         adjust for new SCM_SOCK_FD_TO_PORT.  use int for address size,
 188         not size_t.
 189         (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
 190         call to detect whether recvfrom could be bothered to set the address.
 191         (scm_init_socket): don't call scm_init_addr_buffer.
 192
 193 2001-03-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 194
 195         * debug.c (scm_procedure_source, scm_procedure_environment),

 197         scm_array_index_map_x), sort.c (scm_sort_x, scm_sort,

 201         scm_transpose_array, scm_enclose_array, scm_array_in_bounds_p,
 202         scm_uniform_vector_ref, scm_array_set_x, scm_uniform_array_read_x,
 203         scm_uniform_array_write, scm_bit_set_star_x, scm_bit_count_star,
 204         scm_array_to_list, scm_array_prototype), validate.h
 205         (SCM_VALIDATE_NUMBER_COPY):  Don't call function scm_wta, call
 206         scm_misc_error or scm_wrong_type_arg instead.
 207
 208         * validate.h (SCM_WTA, RETURN_SCM_WTA):  Deprecated.

 224         script_get_backslash, script_read_arg), unif.c (scm_cvref):  Don't
 225         call function scm_wta, call scm_misc_error or scm_wrong_type_arg
 226         instead.
 227
 228 2001-03-04  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

 243         (scm_m_lambda): Check for duplicate arguments.
 244         (scm_ceval, scm_deval): When executing a body: only cons a new
 245         toplevel environment frame when it is different from the
 246         existing one; use EVALCAR instead of SIDEVAL so that we can properly
 247         check for empty combinations; use SCM_EVALIM2 for the same reason
 248         in the non-toplevel loop.
 249         (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
 250         New labels with the meaning of their non-"nontoplevel" partners,
 251         but they are used when it is known that the body is not evaluated at
 252         top-level.
 253         (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
 254         reporting for empty combinations.

 312
 313 2001-02-23  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
 314
 315         * ports.c, ports.h (scm_c_read, scm_c_write): New functions.
 316
 317         * ports.h (SCM_READ_BUFFER_EMPTY_P): New macro.
 318
 319 2001-02-24  Neil Jerram  <neil@ossau.uklinux.net>
 320
 321         * numbers.c (scm_two_doubles, scm_sys_expt, scm_sys_atan2,
 322         scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
 323         since use of `z' suggests that the arguments may be complex.
 324
 325         * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring
 326         typos.
 327
 328 2001-02-23  Neil Jerram  <neil@ossau.uklinux.net>
 329
 330         * dump.c (scm_binary_write, scm_binary_read), eval.c
 331         (scm_primitive_eval), guardians.c (scm_guardian_destroyed_p,
 332         scm_guardian_greedy_p, scm_make_guardian), fports.c
 333         (scm_file_port_p): Minor docstring fixes.
 334
 335 2001-02-22  Marius Vollmer  <mvo@zagadka.ping.de>
 336
 337         * load.c (load): Use scm_primitive_eval_x instead of scm_i_eval_x.
 338
 339         * goops.c (scm_add_method, DEFVAR): Use scm_eval instead of
 340         scm_i_eval.
 341         (make_class_from_template): Do not bother to set the current
 342         module around the call to DEFVAR, scm_eval takes care of that.
 343         (scm_init_goops): Make scm_module_goops and
 344         scm_goops_lookup_closure permanent objects.
 345
 346         * eval.c (scm_ceval, scm_deval): When evaluating expressions on
 347         top level, create a fresh top-level environment for each
 348         expression instead of mutating the exisint frame.  This is
 349         important when that frame is closed over.
 350
 351         * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
 352         SCM_DIGSPERLONG instead of DIGSPERLONG.
 353
 354 2001-02-21  Marius Vollmer  <mvo@zagadka.ping.de>
 355
 356         * eval.c (scm_ceval, scm_deval): Check for wrong number of args
 357         before applying arrow procedure in `cond' and before applying
 358         receiver procedure in call-with-current-continuation.
 359         (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
 360         macro.  The argument is expanded more than one time.
 361
 362         * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
 363         SCM_BIGDIG instead of BIGDIG.  Thanks to Steven G. Johnson!
 364
 365 2001-02-20  Marius Vollmer  <mvo@zagadka.ping.de>
 366
 367         * guile-doc-snarf.in, guile-func-name-check.in: Added copyright

 412
 413 2001-02-16  Neil Jerram  <neil@ossau.uklinux.net>
 414
 415         * guile-snarf.awk.in: Quote any `@'s that occur in Scheme names,

 482 2001-02-15  Marius Vollmer  <mvo@zagadka.ping.de>
 483
 484         * symbols.c (scm_mem2symbol): Put a empty statement after the
 485         next_symbol label.  This is mandated by ANSI, appearantly.
 486
 487 2001-02-13  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
 488
 489         * gc_os_dep.c: Do not include <linux/version.h>.  It makes no
 490         sense to compile for a specific kernel version.  Do not include
 491         <asm/signal.h> while defining __KERNEL__.  This hack should no
 492         longer be needed and caused problems.
 493
 494 2001-02-13  Marius Vollmer  <mvo@zagadka.ping.de>
 495
 496         * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of
 497         SCM_CEVAL when evaluating subforms of `begin' forms.  SCM_CEVAL

 506         Fix evaluator so that top-level expressions are correctly
 507         evaluated with respect to the module system.
 508
 509         * modules.h. modules.c (scm_current_module_lookup_closure): New
 510         function.
 511
 512         * eval.h (scm_primitive_eval, scm_primitive_eval_x): New
 513         prototypes.
 514         (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
 515         names to better reflect their meaning.
 516
 517         * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
 518         evaluated at top-level and synronize lookup closure before
 519         executing every subform.
 520         (scm_primitve_eval_x, scm_primitive_eval): New functions.
 521         (scm_eval_x, scm_eval): Reimplement in terms of

 523
 524 2001-02-09  Marius Vollmer  <mvo@zagadka.ping.de>
 525
 526         * macros.c (scm_macro_name, scm_macro_transformer): Use
 527         SCM_SMOB_DATA instead of SCM_CDR.  Provided by Martin Grabmueller.
 528         Thanks!
 529
 530 2001-02-10  Keisuke Nishida  <kxn30@po.cwru.edu>
 531
 532         * dump.c (scm_store_bytes): Store data size before data.
 533         (scm_restore_bytes): Restore data size.  Takes a pointer to size.
 534         * dump.h (scm_restore_bytes): Updated.
 535
 536 2001-02-09  Keisuke Nishida  <kxn30@po.cwru.edu>
 537
 538         * dump.c: Use double cells for update schedule.
 539
 540 2001-02-08  Keisuke Nishida  <kxn30@po.cwru.edu>
 541
 542         * ports.c (scm_unread_char): Take an optional argument.
 543
 544 2001-02-08  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
 545
 546         * modules.h (scm_selected_module, scm_current_module): Renamed
 547         scm_selected_module to scm_current_module to synchronize Scheme
 548         and C names.
 549         (scm_select_module, scm_set_current_module): Likewise.  Changed
 550         all uses.
 551
 552         * ports.c (scm_port_for_each): Make a snapshot of the port table
 553         before iterating over it.  The table might change while the user
 554         code is running.  With the snapshot, the user can depend on the
 555         fact that each port that existed at the start of the iteration is
 556         encountered exactly once.  (ice-9 popen) depends on this.
 557
 558 2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 559
 560         * strings.h (SCM_STRING_MAX_LENGTH):  New macro.
 561
 562         * strings.c (scm_makstr, scm_take_str, scm_make_string):  Added
 563         range checking for the size parameter.  Thanks to Martin
 564         Grabmueller for the hint.
 565
 566         (scm_makstr):  Reordered string initialization to make interrupt
 567         deferring unnecessary.
 568
 569         * vectors.c (scm_make_vector):  Fixed range checking.
 570
 571 2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 572
 573         * vectors.h (SCM_VECTOR_MAX_LENGTH):  New macro.
 574
 575         * vectors.c (scm_make_vector, scm_c_make_vector):  Improved the
 576         checking of the size parameter for type correctness and valid
 577         range.  Thanks to Rob Browning for reporting the problem.  Instead
 578         of deferring interrupts, scm_remember_upto_here_1 is used.
 579
 580 2001-02-05  Keisuke Nishida  <kxn30@po.cwru.edu>
 581
 582         * dump.c (scm_store_cell_object, scm_restore_cell_object): Removed.
 583         (scm_dump_cell_update): Removed.
 584         (scm_dump_update): Renamed from scm_dump_object_update.
 585         (scm_restore_string, scm_restore_bytes, scm_restore_word): Takes
 586         a pointer instead of returning a value.
 587         * keywords.c (keyword_undump): Updated.
 588
 589 2001-02-05  Keisuke Nishida  <kxn30@po.cwru.edu>
 590
 591         * dump.c, dump.h: Modified a lot.
 592         (SCM_DUMP_COOKIE): Version 0.1
 593         (scm_dump_mark): Removed.
 594         (scm_restore_cell_object, scm_store_cell_object): New functions.

 598         New slots: dump, undump.
 599         * smob.c (scm_make_smob_type, scm_set_smob_dump, scm_set_smob_undump):
 600         Updated.
 601
 602         * keywords.c (keyword_dump): Renamed from keyword_dealloc.
 603         (keyword_undump): Renamed from keyword_alloc.

 609         the deprecated SCM_DOUBLE_CELLP.
 610
 611         * tags.h (SCM_DOUBLE_CELLP): deprecated.
 612
 613 2001-02-02  Keisuke Nishida  <kxn30@po.cwru.edu>
 614
 615         * dump.c, dump.h: New files.
 616         * Makefile.am: Added dump.c, dump.h, dump.x, dump.doc.
 617         * init.c: #include "libguile/dump.h".
 618         (scm_init_guile_1): Call scm_init_dump.
 619         * smob.h (scm_smob_descriptor): New slots: dump_mark,

 684
 685         The following patch was sent by Martin Grabmueller.  It makes sure

 944
 945         * fports.c (fport_write): bugfix: handle short writes for
