 112
 113         * ports.c (scm_port_column): Docstring fixes: (i) port-line arg is
 114         not optional (ii) "recommend" spelling correction.
 115
 116 2001-03-08  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
 117
 118         * ramap.c (racp): Removed optimization which caused array copying
 119         to fail if the two arrays shared storage.  Re-inserted the IVDEP
 120         macros removed in the change of 2000-03-09.  (Don't really have a
 121         complete grasp of what they are for, but they seem to be necessary
 122         on Crays.  This needs testing!)  Thanks to Miroslav Silovic.
 123
 124         * hash.c (scm_string_hash): Don't downcase characters.
 125
 126 2001-03-07  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

 135
 136         * validate.h: Code formatting.
 137
 138 2001-03-07  Keisuke Nishida  <kxn30@po.cwru.edu>
 139
 140         * Makefile.am (*.x): Add dependency on snarf.h and guile-doc-snarf.in.
 141         (*.doc): Add dependency on guile-snarf.awk.in.
 142
 143         * guile-snarf.awk.in: Neglect spaces at the end of
 144         SCM_SNARF_DOCSTRING_END.  Skip lines "# NN ..." in the
 145         middle of docstrings.  (To avoid the problem with gcc-2.96.)
 146
 147 2001-03-06  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 148
 149         * coop-threads.c (scm_call_with_new_thread), load.c

 152         scm_struct_ref, scm_struct_set_x):  Don't use SCM_ASSERT to
 153         (potentially) issue a scm-misc-error or wrong-num-args error
 154         message.
 155
 156         * load.c (scm_search_path):  Use SCM_ASSERT_TYPE to give details
 157         about the expected type with the wrong-type-arg error message.
 158
 159         * smob.c (scm_make_smob):  Abort on misuse of smob - it indicates
 160         a C level bug that can't be fixed from scheme anyway.
 161
 162 2001-03-05  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
 163
 164         * eval.c (scm_m_letstar): Removed check for duplicate bindings.
 165         Duplicate bindings are OK in a let* since a let* is semantically
 166         equivalent to a nested set of let:s.
 167
 168 2001-03-05  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>
 169
 170         * print.c (scm_print_options): Fixed texinfo in docstring.
 171
 172         * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
 173         the underlying functions getservent, getprotoent or getnetent
 174         return NULL instead of signalling an error.
 175
 176 2001-03-04  Gary Houston  <ghouston@arglist.com>
 177
 178         * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
 179         taking an unexpectedly large filename for an AF_UNIX socket from
 180         bind/connect/sendto (thanks to Martin Grabmueller).
 181
 182         * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
 183         former and adjusted the latter.
 184         (scm_socket, scm_socketpair): cosmetic changes.
 185         (scm_getsockopt, scm_setsockopt): declare optlen as int, not
 186         size_t as socklen_t substitute.  don't restrict args/return values
 187         to INUM: allow full range of int or size_t.
 188         (scm_fill_sockaddr): check arguments before allocating memory, to
 189         avoid leakage.  use malloc, not scm_must_malloc.
 190         (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
 191         substitute.  free the sockaddr structure before throwing an error.
 192         (scm_init_add_buffer): procedure removed, together with its static
 193         buffer scm_addr_buffer, which wouldn't be thread safe.  instead,
 194         define a macro MAX_ADDR_SIZE and declare the buffer where needed.
 195         (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
 196         scm_sendto): use a local buffer instead of scm_addr_buffer.
 197         adjust for new SCM_SOCK_FD_TO_PORT.  use int for address size,
 198         not size_t.
 199         (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
 200         call to detect whether recvfrom could be bothered to set the address.
 201         (scm_init_socket): don't call scm_init_addr_buffer.
 202
 203 2001-03-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

 212         scm_uniform_vector_ref, scm_array_set_x, scm_uniform_array_read_x,
 213         scm_uniform_array_write, scm_bit_set_star_x, scm_bit_count_star,
 214         scm_array_to_list, scm_array_prototype), validate.h
 215         (SCM_VALIDATE_NUMBER_COPY):  Don't call function scm_wta, call
 216         scm_misc_error or scm_wrong_type_arg instead.
 217
 218         * validate.h (SCM_WTA, RETURN_SCM_WTA):  Deprecated.

 230         (get_bvec, MARK), goops.c (scm_primitive_generic_generic),
 231         options.c (scm_options), ports.c (scm_remove_from_port_table),

 233         scm_lreadparen, scm_lreadrecparen), script.c (script_get_octal,
 234         script_get_backslash, script_read_arg), unif.c (scm_cvref):  Don't
 235         call function scm_wta, call scm_misc_error or scm_wrong_type_arg
 236         instead.
 237
 238 2001-03-04  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>

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

 316 2001-02-28  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 317
 318         * __scm.h (SCM_ASSERT_TYPE):  Add missing macro parameter.
 319         (Obviously nobody compiles with SCM_RECKLESS defined...)
 320
 321         * validate.h (SCM_ASSERT_RANGE):  Use the argument number.
 322
 323 2001-02-23  Mikael Djurfeldt  <mdj@linnaeus.mit.edu>
 324
 325         * ports.c, ports.h (scm_c_read, scm_c_write): New functions.
 326
 327         * ports.h (SCM_READ_BUFFER_EMPTY_P): New macro.
 328
 329 2001-02-24  Neil Jerram  <neil@ossau.uklinux.net>
 330
 331         * numbers.c (scm_two_doubles, scm_sys_expt, scm_sys_atan2,
 332         scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
 333         since use of `z' suggests that the arguments may be complex.
 334
 335         * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring
 336         typos.
 337
 338 2001-02-23  Neil Jerram  <neil@ossau.uklinux.net>
 339
 340         * dump.c (scm_binary_write, scm_binary_read), eval.c
 341         (scm_primitive_eval), guardians.c (scm_guardian_destroyed_p,
 342         scm_guardian_greedy_p, scm_make_guardian), fports.c
 343         (scm_file_port_p): Minor docstring fixes.
 344
 345 2001-02-22  Marius Vollmer  <mvo@zagadka.ping.de>
 346
 347         * load.c (load): Use scm_primitive_eval_x instead of scm_i_eval_x.
 348
 349         * goops.c (scm_add_method, DEFVAR): Use scm_eval instead of
 350         scm_i_eval.
 351         (make_class_from_template): Do not bother to set the current
 352         module around the call to DEFVAR, scm_eval takes care of that.
 353         (scm_init_goops): Make scm_module_goops and
 354         scm_goops_lookup_closure permanent objects.
 355
 356         * eval.c (scm_ceval, scm_deval): When evaluating expressions on
 357         top level, create a fresh top-level environment for each
 358         expression instead of mutating the exisint frame.  This is
 359         important when that frame is closed over.
 360
 361         * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
 362         SCM_DIGSPERLONG instead of DIGSPERLONG.
 363
 364 2001-02-21  Marius Vollmer  <mvo@zagadka.ping.de>
 365
 366         * eval.c (scm_ceval, scm_deval): Check for wrong number of args
 367         before applying arrow procedure in `cond' and before applying
 368         receiver procedure in call-with-current-continuation.
 369         (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
 370         macro.  The argument is expanded more than one time.
 371
 372         * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
 373         SCM_BIGDIG instead of BIGDIG.  Thanks to Steven G. Johnson!
 374
 375 2001-02-20  Marius Vollmer  <mvo@zagadka.ping.de>
 376
 377         * guile-doc-snarf.in, guile-func-name-check.in: Added copyright

 420         Changed `Returns' to `Return'.

 422
 423 2001-02-16  Neil Jerram  <neil@ossau.uklinux.net>
 424
 425         * guile-snarf.awk.in: Quote any `@'s that occur in Scheme names,
 426         by doubling them to `@@'.
 427
 428 2001-02-16  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

 491
 492 2001-02-15  Marius Vollmer  <mvo@zagadka.ping.de>
 493
 494         * symbols.c (scm_mem2symbol): Put a empty statement after the
 495         next_symbol label.  This is mandated by ANSI, appearantly.
 496
 497 2001-02-13  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
 498
 499         * gc_os_dep.c: Do not include <linux/version.h>.  It makes no
 500         sense to compile for a specific kernel version.  Do not include
 501         <asm/signal.h> while defining __KERNEL__.  This hack should no
 502         longer be needed and caused problems.
 503
 504 2001-02-13  Marius Vollmer  <mvo@zagadka.ping.de>
 505
 506         * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of
 507         SCM_CEVAL when evaluating subforms of `begin' forms.  SCM_CEVAL
 508         can not deal with immediates.
 509

 513
 514 2001-02-11  Marius Vollmer  <mvo@zagadka.ping.de>
 515
 516         Fix evaluator so that top-level expressions are correctly
 517         evaluated with respect to the module system.
 518
 519         * modules.h. modules.c (scm_current_module_lookup_closure): New
 520         function.
 521
 522         * eval.h (scm_primitive_eval, scm_primitive_eval_x): New
 523         prototypes.
 524         (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
 525         names to better reflect their meaning.
 526
 527         * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
 528         evaluated at top-level and synronize lookup closure before
 529         executing every subform.
 530         (scm_primitve_eval_x, scm_primitive_eval): New functions.
 531         (scm_eval_x, scm_eval): Reimplement in terms of
 532         scm_primitive_eval_x and scm_primitive_eval, respectively.
 533
 534 2001-02-09  Marius Vollmer  <mvo@zagadka.ping.de>
 535
 536         * macros.c (scm_macro_name, scm_macro_transformer): Use
 537         SCM_SMOB_DATA instead of SCM_CDR.  Provided by Martin Grabmueller.
 538         Thanks!
 539
 540 2001-02-10  Keisuke Nishida  <kxn30@po.cwru.edu>
 541
 542         * dump.c (scm_store_bytes): Store data size before data.
 543         (scm_restore_bytes): Restore data size.  Takes a pointer to size.
 544         * dump.h (scm_restore_bytes): Updated.
 545
 546 2001-02-09  Keisuke Nishida  <kxn30@po.cwru.edu>
 547
 548         * dump.c: Use double cells for update schedule.
 549
 550 2001-02-08  Keisuke Nishida  <kxn30@po.cwru.edu>
 551
 552         * ports.c (scm_unread_char): Take an optional argument.
 553
 554 2001-02-08  Marius Vollmer  <marius.vollmer@uni-dortmund.de>
 555
 556         * modules.h (scm_selected_module, scm_current_module): Renamed
 557         scm_selected_module to scm_current_module to synchronize Scheme
 558         and C names.
 559         (scm_select_module, scm_set_current_module): Likewise.  Changed
 560         all uses.
 561
 562         * ports.c (scm_port_for_each): Make a snapshot of the port table
 563         before iterating over it.  The table might change while the user
 564         code is running.  With the snapshot, the user can depend on the
 565         fact that each port that existed at the start of the iteration is
 566         encountered exactly once.  (ice-9 popen) depends on this.
 567
 568 2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 569
 570         * strings.h (SCM_STRING_MAX_LENGTH):  New macro.
 571
 572         * strings.c (scm_makstr, scm_take_str, scm_make_string):  Added
 573         range checking for the size parameter.  Thanks to Martin
 574         Grabmueller for the hint.
 575
 576         (scm_makstr):  Reordered string initialization to make interrupt
 577         deferring unnecessary.
 578
 579         * vectors.c (scm_make_vector):  Fixed range checking.
 580
 581 2001-02-08  Dirk Herrmann  <D.Herrmann@tu-bs.de>
 582
 583         * vectors.h (SCM_VECTOR_MAX_LENGTH):  New macro.
 584
 585         * vectors.c (scm_make_vector, scm_c_make_vector):  Improved the
 586         checking of the size parameter for type correctness and valid
 587         range.  Thanks to Rob Browning for reporting the problem.  Instead
 588         of deferring interrupts, scm_remember_upto_here_1 is used.
 589
 590 2001-02-05  Keisuke Nishida  <kxn30@po.cwru.edu>
 591
 592         * dump.c (scm_store_cell_object, scm_restore_cell_object): Removed.
 593         (scm_dump_cell_update): Removed.
 594         (scm_dump_update): Renamed from scm_dump_object_update.
 595         (scm_restore_string, scm_restore_bytes, scm_restore_word): Takes
 596         a pointer instead of returning a value.
 597         * keywords.c (keyword_undump): Updated.
 598
 599 2001-02-05  Keisuke Nishida  <kxn30@po.cwru.edu>
 600
 601         * dump.c, dump.h: Modified a lot.
 602         (SCM_DUMP_COOKIE): Version 0.1
 603         (scm_dump_mark): Removed.
 604         (scm_restore_cell_object, scm_store_cell_object): New functions.
 605
 606         * smob.h (scm_smob_descriptor): Removed slots: dump_mark,
 607         dump_dealloc, dump_store, undump_alloc, undump_restore, undump_init.
 608         New slots: dump, undump.
 609         * smob.c (scm_make_smob_type, scm_set_smob_dump, scm_set_smob_undump):
 610         Updated.
 611
 612         * keywords.c (keyword_dump): Renamed from keyword_dealloc.
 613         (keyword_undump): Renamed from keyword_alloc.
 614         (scm_init_keywords): Set keyword_dump and keyword_undump.
 615
 616 2001-02-03  Michael Livshin  <mlivshin@bigfoot.com>
 617
 618         * gc.c (DOUBLECELL_ALIGNED_P): new macro, a better-named analog of
 619         the deprecated SCM_DOUBLE_CELLP.
 620
 621         * tags.h (SCM_DOUBLE_CELLP): deprecated.
 622
 623 2001-02-02  Keisuke Nishida  <kxn30@po.cwru.edu>
 624
 625         * dump.c, dump.h: New files.
 626         * Makefile.am: Added dump.c, dump.h, dump.x, dump.doc.

 954
 955         * fports.c (fport_write): bugfix: handle short writes for
