  91 2001-03-08  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
  92
  93         * ramap.c (racp): Removed optimization which caused array copying
  94         to fail if the two arrays shared storage.  Re-inserted the IVDEP
  95         macros removed in the change of 2000-03-09.  (Don't really have a
  96         complete grasp of what they are for, but they seem to be necessary
  97         on Crays.  This needs testing!)  Thanks to Miroslav Silovic.
  98
  99         * hash.c (scm_string_hash): Don't downcase characters.
 100
 101 2001-03-07  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
 102
 103         * symbols.c (scm_symbols_prehistory): Changed symbol hash table

 110
 111         * validate.h: Code formatting.
 112
 113 2001-03-07  Keisuke Nishida  <kxn30@po.cwru.edu>
 114
 115         * Makefile.am (*.x): Add dependency on snarf.h and guile-doc-snarf.in.
 116         (*.doc): Add dependency on guile-snarf.awk.in.
 117
 118         * guile-snarf.awk.in: Neglect spaces at the end of
 119         SCM_SNARF_DOCSTRING_END.  Skip lines "# NN ..." in the
 120         middle of docstrings.  (To avoid the problem with gcc-2.96.)
 121
 122 2001-03-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 123
 124         * coop-threads.c (scm_call_with_new_thread), load.c

 127         scm_struct_ref, scm_struct_set_x):  Don't use SCM_ASSERT to
 128         (potentially) issue a scm-misc-error or wrong-num-args error
 129         message.
 130
 131         * load.c (scm_search_path):  Use SCM_ASSERT_TYPE to give details
 132         about the expected type with the wrong-type-arg error message.
 133
 134         * smob.c (scm_make_smob):  Abort on misuse of smob - it indicates
 135         a C level bug that can't be fixed from scheme anyway.
 136
 137 2001-03-05  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
 138
 139         * eval.c (scm_m_letstar): Removed check for duplicate bindings.
 140         Duplicate bindings are OK in a let* since a let* is semantically
 141         equivalent to a nested set of let:s.
 142
 143 2001-03-05  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>
 144
 145         * print.c (scm_print_options): Fixed texinfo in docstring.
 146
 147         * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
 148         the underlying functions getservent, getprotoent or getnetent
 149         return NULL instead of signalling an error.
 150
 151 2001-03-04  Gary Houston  <ghouston@arglist.com>
 152
 153         * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
 154         taking an unexpectedly large filename for an AF_UNIX socket from
 155         bind/connect/sendto (thanks to Martin Grabmueller).
 156
 157         * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
 158         former and adjusted the latter.
 159         (scm_socket, scm_socketpair): cosmetic changes.
 160         (scm_getsockopt, scm_setsockopt): declare optlen as int, not
 161         size_t as socklen_t substitute.  don't restrict args/return values
 162         to INUM: allow full range of int or size_t.
 163         (scm_fill_sockaddr): check arguments before allocating memory, to
 164         avoid leakage.  use malloc, not scm_must_malloc.
 165         (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
 166         substitute.  free the sockaddr structure before throwing an error.
 167         (scm_init_add_buffer): procedure removed, together with its static
 168         buffer scm_addr_buffer, which wouldn't be thread safe.  instead,
 169         define a macro MAX_ADDR_SIZE and declare the buffer where needed.
 170         (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
 171         scm_sendto): use a local buffer instead of scm_addr_buffer.
 172         adjust for new SCM_SOCK_FD_TO_PORT.  use int for address size,
 173         not size_t.
 174         (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
 175         call to detect whether recvfrom could be bothered to set the address.
 176         (scm_init_socket): don't call scm_init_addr_buffer.
 177
 178 2001-03-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

 186         scm_transpose_array, scm_enclose_array, scm_array_in_bounds_p,
 187         scm_uniform_vector_ref, scm_array_set_x, scm_uniform_array_read_x,
 188         scm_uniform_array_write, scm_bit_set_star_x, scm_bit_count_star,
 189         scm_array_to_list, scm_array_prototype), validate.h
 190         (SCM_VALIDATE_NUMBER_COPY):  Don't call function scm_wta, call
 191         scm_misc_error or scm_wrong_type_arg instead.
 192
 193         * validate.h (SCM_WTA, RETURN_SCM_WTA):  Deprecated.
 194
 195 2001-03-04  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

 208         scm_lreadparen, scm_lreadrecparen), script.c (script_get_octal,
 209         script_get_backslash, script_read_arg), unif.c (scm_cvref):  Don't
 210         call function scm_wta, call scm_misc_error or scm_wrong_type_arg
 211         instead.
 212
 213 2001-03-04  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
 214

 227         (scm_c_improper_memq): New function.
 228         (scm_m_lambda): Check for duplicate arguments.
 229         (scm_ceval, scm_deval): When executing a body: only cons a new
 230         toplevel environment frame when it is different from the
 231         existing one; use EVALCAR instead of SIDEVAL so that we can properly
 232         check for empty combinations; use SCM_EVALIM2 for the same reason
 233         in the non-toplevel loop.
 234         (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
 235         New labels with the meaning of their non-"nontoplevel" partners,
 236         but they are used when it is known that the body is not evaluated at
 237         top-level.
 238         (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
 239         reporting for empty combinations.

 292
 293         * __scm.h (SCM_ASSERT_TYPE):  Add missing macro parameter.

 296         * validate.h (SCM_ASSERT_RANGE):  Use the argument number.
 297
 298 2001-02-23  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

 313 2001-02-23  Neil Jerram  <neil@ossau.uklinux.net>
 314
 315         * dump.c (scm_binary_write, scm_binary_read), eval.c
 316         (scm_primitive_eval), guardians.c (scm_guardian_destroyed_p,
 317         scm_guardian_greedy_p, scm_make_guardian), fports.c
 318         (scm_file_port_p): Minor docstring fixes.
 319
 320 2001-02-22  Marius Vollmer  <mvo@zagadka.ping.de>
 321
 322         * load.c (load): Use scm_primitive_eval_x instead of scm_i_eval_x.
 323
 324         * goops.c (scm_add_method, DEFVAR): Use scm_eval instead of
 325         scm_i_eval.
 326         (make_class_from_template): Do not bother to set the current
 327         module around the call to DEFVAR, scm_eval takes care of that.
 328         (scm_init_goops): Make scm_module_goops and
 329         scm_goops_lookup_closure permanent objects.
 330
 331         * eval.c (scm_ceval, scm_deval): When evaluating expressions on
 332         top level, create a fresh top-level environment for each
 333         expression instead of mutating the exisint frame.  This is
 334         important when that frame is closed over.
 335
 336         * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
 337         SCM_DIGSPERLONG instead of DIGSPERLONG.
 338
 339 2001-02-21  Marius Vollmer  <mvo@zagadka.ping.de>
 340
 341         * eval.c (scm_ceval, scm_deval): Check for wrong number of args
 342         before applying arrow procedure in `cond' and before applying
 343         receiver procedure in call-with-current-continuation.
 344         (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
 345         macro.  The argument is expanded more than one time.
 346
 347         * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
 348         SCM_BIGDIG instead of BIGDIG.  Thanks to Steven G. Johnson!
 349
 350 2001-02-20  Marius Vollmer  <mvo@zagadka.ping.de>

 397
 398 2001-02-16  Neil Jerram  <neil@ossau.uklinux.net>
 399
 400         * guile-snarf.awk.in: Quote any `@'s that occur in Scheme names,
 401         by doubling them to `@@'.

 461
 462         * dump.c (scm_undump): Use SCM_CARLOC/SCM_CDRLOC to obtain the

 464         Use scm_sizet to obtain the length of strings.
 465         (Thanks to Matthias Koeppe)
 466
 467 2001-02-15  Marius Vollmer  <mvo@zagadka.ping.de>
 468
 469         * symbols.c (scm_mem2symbol): Put a empty statement after the
 470         next_symbol label.  This is mandated by ANSI, appearantly.
 471
 472 2001-02-13  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
 473
 474         * gc_os_dep.c: Do not include <linux/version.h>.  It makes no
 475         sense to compile for a specific kernel version.  Do not include
 476         <asm/signal.h> while defining __KERNEL__.  This hack should no
 477         longer be needed and caused problems.
 478
 479 2001-02-13  Marius Vollmer  <mvo@zagadka.ping.de>
 480
 481         * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of
 482         SCM_CEVAL when evaluating subforms of `begin' forms.  SCM_CEVAL
 483         can not deal with immediates.
 484
 485 2001-02-12  Keisuke Nishida  <kxn30@po.cwru.edu>
 486
 487         * list.c (scm_list_copy): Validate the first argument.
 488
 489 2001-02-11  Marius Vollmer  <mvo@zagadka.ping.de>
 490
 491         Fix evaluator so that top-level expressions are correctly
 492         evaluated with respect to the module system.
 493
 494         * modules.h. modules.c (scm_current_module_lookup_closure): New
 495         function.
 496
 497         * eval.h (scm_primitive_eval, scm_primitive_eval_x): New
 498         prototypes.
 499         (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
 500         names to better reflect their meaning.
 501
 502         * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
 503         evaluated at top-level and synronize lookup closure before
 504         executing every subform.
 505         (scm_primitve_eval_x, scm_primitive_eval): New functions.
 506         (scm_eval_x, scm_eval): Reimplement in terms of
 507         scm_primitive_eval_x and scm_primitive_eval, respectively.
 508
 509 2001-02-09  Marius Vollmer  <mvo@zagadka.ping.de>
 510
 511         * macros.c (scm_macro_name, scm_macro_transformer): Use
 512         SCM_SMOB_DATA instead of SCM_CDR.  Provided by Martin Grabmueller.
 513         Thanks!
 514
 515 2001-02-10  Keisuke Nishida  <kxn30@po.cwru.edu>
 516
 517         * dump.c (scm_store_bytes): Store data size before data.
 518         (scm_restore_bytes): Restore data size.  Takes a pointer to size.
 519         * dump.h (scm_restore_bytes): Updated.
 520
 521 2001-02-09  Keisuke Nishida  <kxn30@po.cwru.edu>
 522
 523         * dump.c: Use double cells for update schedule.
 524
 525 2001-02-08  Keisuke Nishida  <kxn30@po.cwru.edu>
 526
 527         * ports.c (scm_unread_char): Take an optional argument.
 528
 529 2001-02-08  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
 530
 531         * modules.h (scm_selected_module, scm_current_module): Renamed
 532         scm_selected_module to scm_current_module to synchronize Scheme
 533         and C names.
 534         (scm_select_module, scm_set_current_module): Likewise.  Changed
 535         all uses.
 536
 537         * ports.c (scm_port_for_each): Make a snapshot of the port table
 538         before iterating over it.  The table might change while the user
 539         code is running.  With the snapshot, the user can depend on the
 540         fact that each port that existed at the start of the iteration is
 541         encountered exactly once.  (ice-9 popen) depends on this.
 542
 543 2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 544
 545         * strings.h (SCM_STRING_MAX_LENGTH):  New macro.
 546
 547         * strings.c (scm_makstr, scm_take_str, scm_make_string):  Added
 548         range checking for the size parameter.  Thanks to Martin
 549         Grabmueller for the hint.
 550
 551         (scm_makstr):  Reordered string initialization to make interrupt
 552         deferring unnecessary.
 553
 554         * vectors.c (scm_make_vector):  Fixed range checking.
 555
 556 2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 557
 558         * vectors.h (SCM_VECTOR_MAX_LENGTH):  New macro.
 559
 560         * vectors.c (scm_make_vector, scm_c_make_vector):  Improved the
 561         checking of the size parameter for type correctness and valid
 562         range.  Thanks to Rob Browning for reporting the problem.  Instead
 563         of deferring interrupts, scm_remember_upto_here_1 is used.
 564
 565 2001-02-05  Keisuke Nishida  <kxn30@po.cwru.edu>
 566
 567         * dump.c (scm_store_cell_object, scm_restore_cell_object): Removed.
 568         (scm_dump_cell_update): Removed.
 569         (scm_dump_update): Renamed from scm_dump_object_update.
 570         (scm_restore_string, scm_restore_bytes, scm_restore_word): Takes
 571         a pointer instead of returning a value.
 572         * keywords.c (keyword_undump): Updated.
 573
 574 2001-02-05  Keisuke Nishida  <kxn30@po.cwru.edu>

 577         (SCM_DUMP_COOKIE): Version 0.1
 578         (scm_dump_mark): Removed.
 579         (scm_restore_cell_object, scm_store_cell_object): New functions.
 580
 581         * smob.h (scm_smob_descriptor): Removed slots: dump_mark,
 582         dump_dealloc, dump_store, undump_alloc, undump_restore, undump_init.
 583         New slots: dump, undump.
 584         * smob.c (scm_make_smob_type, scm_set_smob_dump, scm_set_smob_undump):
 585         Updated.
 586
 587         * keywords.c (keyword_dump): Renamed from keyword_dealloc.
 588         (keyword_undump): Renamed from keyword_alloc.
 589         (scm_init_keywords): Set keyword_dump and keyword_undump.
 590

 592
 593         * gc.c (DOUBLECELL_ALIGNED_P): new macro, a better-named analog of
 594         the deprecated SCM_DOUBLE_CELLP.
 595
 596         * tags.h (SCM_DOUBLE_CELLP): deprecated.
 597
 598 2001-02-02  Keisuke Nishida  <kxn30@po.cwru.edu>
 599
 600         * dump.c, dump.h: New files.
 601         * Makefile.am: Added dump.c, dump.h, dump.x, dump.doc.
 602         * init.c: #include "libguile/dump.h".
 603         (scm_init_guile_1): Call scm_init_dump.
 604         * smob.h (scm_smob_descriptor): New slots: dump_mark,

 929
 930         * fports.c (fport_write): bugfix: handle short writes for
