 248
 249         * configure.in and acconfig.h: check whether the compiler supports
 250         volatile functions (and whether abort() is volatile). In member
 251         functions, return *this after calling abort() for those stupid
 252         compilers (they would otherwise abort with an error).
 253
 254         * tbl-tools/ and tbl-example/ directoies added.

 266         to be a reserved word in gcc 2.7, so prefix it with `_'
 267
 268         * c++-lib/src/asn-bits.C: dereferencing pointer to member function
 269         is neither necessary nor allowed
 270
 271         * c++-lib/src/asn-type.C: "virtual" removed from functions. (fix
 272         due to changed C++ language.)

 275
 276         * deep copying code added to C++ backend generated assignment
 277         operators.

 283         reserved words in new C++ (supported by gcc since version 2.6).
 284
 285         * new options -mA and -mC for snacc(1) that switch the names used
 286         between those defined in the ASN.1 files and those used in the
 287         generated C++ code. enum type MetaNameStyle introduced.
 288
 289         * c++-lib/src/tcl-if.C: duplicate code merged into a new function
 290         SnaccTcl::gettypedesc().
 291
 292         * c++-lib/*: long int replaced by AsnIntType at a lot of
 293         places. It shall provide a 32 bit integer type on all platforms.
 294         new type introduced: AsnUIntType (32 bit unsigned integer type).
 295

 302         and TclSetVal functions.
 303
 304         * c++-lib/*/meta.[hC]: introduce an AsnEnumTypeDesc class with its
 305         own TclGetDesc2 function that returns the value names but omits
 306         the numeric values.
 307
 308         * c++-lib/src/tcl-if.C &al.: set Tcl's errorCode variable
 309
 310         * c++-lib/{inc,src}: snacced.[hC] renamed to tcl-if.[hC]. class
 311         SnaccEd renamed to SnaccTcl.
 312
 313         * the PDU flag belongs to the metacode, not only to the tcl
 314         interface. (type and variable named adjusted)
 315
 316 Thu Jul 27 10:27:07 1995  Robert Joop  (rj@rainbow.in-berlin.de)
 317

 322

 324         if both input files exist.
 325
 326         * rfc1155-smi.asn1, rfc1157-snmp.asn1 and rfc1213-mib2.asn1
 327         renamed from 1155-smi.asn1, 1157-snmp.asn1 and 1213-mib2.asn1 to
 328         accomodate to snacc's new file name generation scheme.

 330 Tue Jul 25 13:35:58 1995  Robert Joop  (rj@rainbow.in-berlin.de)
 331
 332         * policy.h: added switch for (en|dis)abling the compilation of the
 333         idl code generator.
 334
 335         * compiler: PrintConditionalIncludeOpen() and
 336         PrintConditionalIncludeClose() moved from
 337         back-ends/c-gen/gen-code.[ch] to back-ends/cond.[ch].
 338
 339         * .../compiler/back-ends/c++-gen/gen-vals.c: use true/false
 340         instead of AsnBool::true/false.
 341
 342         * the compiler is compiled from two files, tbl.h and tbl.c, it
 343         generates itself. for bootstrapping purposes, initial versions are
 344         supplied with the distribution.
 345
 346 Mon Jul 24 14:26:16 1995  Robert Joop  (rj@rainbow.in-berlin.de)
 347
 348         * .../c++-lib: code extracted from AsnOcts::TclGetVal and
 349         AsnOcts::TclSetVal (src/asn-octs.C) into ::debinify and ::binify
 350         (src/meta.C).
 351
 352         * Clone() added to AsnEnum.
 353
 354         * various C++ files: ``#error "..."'' instead of ``#error ...''
 355
 356         * c++-lib/*/asn-list.?: operator == and != return bool instead of int.
 357
 358         * .../maketail: the .C.o default rule now uses CXXFLAGS instead of
 359         CFLAGS for compilation.
 360
 361         * .../c-lib and c++-lib call make recursively to generate the
 362         different depencies for all the different makefiles.
 363
 364         * .../configure looks for tclsh(1)---the tcl-lib uses it to
 365         construct the tclIndex file. .../configure doesn't look for Tcl/Tk
 366         if the tclsh is absent.
 367
 368         * .../configure looks for patch(1)---the c-lib uses it to patch
 369         tbl.h.
 370
 371         * .../configure searches for tree-3.6's libtktree.a and sets
 372         TREELIBS in .../makehead accordingly.
 373
 374         * type table tools and the example merged into the distribution:
 375         .../tbl-tools/ and .../tbl-example.
 376
 377         * dummy action added to config.h.in and config.h rules to trick
 378         many makes' overoptimization.
 379
 380         * snacc -h now prints the usage to stdout.
 381
 382         * bug report address changed to protect an innocent's mailbox :-)
 383
 384         * .../version.h contains the snacc version---it is included in the
 385         compiler source and is used by the .../makefile upon tar-file
 386         generation.
 387
 388         * configure checks for memset(3), memcpy(3) and memcmp(3) and
 389         .../snac.h defines replacements using bzero(3), bcopy(3) and
 390         bcmp(3) if necessary.
 391
 392         * .../compiler/core/mem.c: Realloc() now checks realloc(3)'s
 393         return value.
 394
 395         * changed `_' to `-' in file names.
 396
 397         * file names in .../compiler/back-ends/ have been shortened for
 398         redundant parts (e.g. c_gen/gen_c_code -> c_gen/gen_code or
 399         c++_gen/c++_kwd -> c++_gen/kwd).
 400
 401 Sun Jul 23 12:51:24 1995  Robert Joop  (rj@rainbow.in-berlin.de)
 402
 403         * an additional type description, AsnAliasTypeDesc, for type
 404         definitions of the form ``TypeB ::= TypeA''. see the documentation
 405         for further details.
 406
 407         * allow for more than one PDU per .asn1 file set:
 408         - each type description gets a bool flag, pdu.
 409         - each type description gets accompanied with a create function
 410         that returns a newly allocated object of its mirror type. the type
 411         description contains a pointer to this function. the getTclPDU()
 412         function is deleted.
 413         - compiler/core/meta.h: struct TclPDU becomes a linked list. it
 414         gets a flag `used' to detect invalid command line arguments.
 415
 416         * additional function TclUnsetVal() to delete OPTIONAL members and
 417         SEQUENCE OF and SET OF list elements.
 418
 419         *_getref() gets an additional optional argument, bool
 420         create=false, to faciliate the different member access semantics
 421         of TclGetVal() and TclSetVal().
 422
 423         * to accomodate to snacc's new file name generation scheme:
 424         -  useful.asn1 renamed to asn-useful.asn1
 425         - any-test.[hC] renamed to any.[hC]
 426
 427         * by default, snacc now derives output file names from the .asn1
 428         input file name instead of the module name. a global variable,
 429         `keepbaseG', is used to toggle between old and new behaviour.
 430
 431 Sat Jul 22 22:49:25 1995  Robert Joop  (rj@rainbow.in-berlin.de)
 432
 433         * use install-sh instead of install.sh, to prevent `make' implicit
 434         rules from creating a file called install from it when there is no
 435         makefile.
 436
 437 Mon Feb 20 12:38:00 1995  Robert Joop  (rj@rainbow.in-berlin.de)
 438
 439         * c{,++}_lib/makefile: remove stamp-useful before removing
 440         asn_useful.[hcC].
 441
 442 Sun Feb 19 19:13:50 1995  Robert Joop  (rj@rainbow.in-berlin.de)
 443
 444         * some c{,++}_examples/*/makefile: some make(1)s leave a trailing
 445         `/' on $(@D). since some mkdir(1)s deny their cooperation with
 446         such arguments, this slash has got to be stripped.
 447
 448 Sat Feb 18 14:12:23 1995  Robert Joop  (rj@rainbow.in-berlin.de)
 449
 450         * in a lot of makefiles: dirname(1) and basename(1) do not exist
 451         on every system. so we're using $(@D) and $(@F) instead.
 452
 453         * the code partially relied on big endianess. autoconf is used to
 454         (un)define WORDS_BIGENDIAN accordingly and the byte order
 455         dependent code parts have been fixed.
 456
 457         * instead of relying on (sizeof (int) == 4), autoconf now checks
 458         some integer sizes and cpp is used to select appropiatly sized
 459         integer types.
 460
 461         * c++_lib/{inc/asn_list.h,src/asn_list.C}: #pragma
 462         interface/implementation are GNU specific and need to be wrapped
 463         (by #ifdef __GNUG__).
 464
 465         * configure.in, acconfig.h, misc .C files: added #define
 466         HAVE_VARIABLE_SIZED_AUTOMATIC_ARRAYS (we need to check for this
 467         since not every C++ compiler provides them.)
 468
 469         * snacc.h: added #defines GLASS and KHO for wrapping and enabling
 470         of project and user specific code, resp.
 471
 472 Fri Feb 17 15:27:31 1995  Robert Joop  (rj@rainbow.in-berlin.de)
 473
 474         * c_examples/simple/README: reflect the test script's integration
 475         into the makefile.
 476
 477         * makehead.in, maketail: added a small hack to find gcc's hidden
 478         include directory to pass it to makedepend. this shall enable
 479         X11's makedepend to find .h files a little more the way gcc does.
 480
 481         * configure.in, changes for autoconf 2.x
 482
 483 Mon Feb 13 15:43:10 1995  Robert Joop  (rj@rainbow.in-berlin.de)
 484
 485         * miscelleanous makefiles: make depend builds snacc if and where
 486         necessary.
 487
 488         * makefiles changed to augment CPPFLAGS instead of overriding
 489         them.
 490
 491         * CFLAGS, CXXFLAGS and LDFLAGS moved from the various makefiles to
 492         makehead(.in).
 493
 494         * settings for IEEE_REAL_FMT/IEEE_REAL_LIB moved from
 495         {c_lib,c++_lib}/inc/asn_config.h to acconfig.h.
 496
 497 Mon Oct 10 01:59:50 1994  Robert Joop  (rj@rainbow.in-berlin.de)
 498
 499         * compiler/back_ends/c++_gen/gen_c++_code.c: the list functions
 500         Append(), Prepend(), InsertBefore() and InsertAfter() now set the
 501         current element to the element just inserted.
 502
 503 Sat Oct  8 02:20:20 1994  Robert Joop  (rj@rainbow.in-berlin.de)
 504
 505         * since autoconf substitutes in config.h.bot as well, we can't use
 506         it. therefore it has been renamed to snacc.h and it includes the
 507         config.h (generated by autoconf/configure) and policy.h (edited by
 508         the person who wishes to compile/install/use snacc).
 509
 510         * the compiler is generated with a file it generates itself. for
 511         bootstraping purposes,  an initial version is supplied in the
 512         distribution (c_lib/boot/asn_useful.[hc]).
 513
 514         * to complement the destructors, T::T (const T&) and
 515         T &T::operator = (const T &) have been added to override the
 516         defaults supplied by the compiler. reason: simple pointer
 517         duplication may lead to unreferenced objects and to objects
 518         referenced more than once (on which the destructors delete may
 519         choke).
 520
 521         * three bugs in compiler/back_ends/c++_gen/gen_c++_code.c's list
 522         functions fixed (IBM ENC detected and fixed it at only place only).
 523
 524         * at the same places as the below two points: code for a Tcl
 525         interface added.
 526
 527         * c++_lib/*: meta code for the basic types added. (and a little
 528         glue code in compiler/core/snacc.c)
 529
 530         * compiler/back_ends/c++_gen/gen_c++_code.c: code added that (on
 531          request) added meta information to the C++ classes generated.
 532
 533         * compiler/back_ends/c++_gen/gen_c++_code.c: turned character
 534         pointers into constant character arrays.
 535
 536         * several `unsigned long int' turned into `size_t' (C++ code
 537         only).
 538
 539 Thu Oct  6 19:25:31 1994  Robert Joop  (rj@rainbow.in-berlin.de)
 540
 541         * c++_lib/*: virtual inline functions (the destructor and the
 542         Clone() function) moved from inc/*.h to src/*.C because g++ turns
 543         every one of them into a static non-inline function in every file
 544         where the .h file gets included.
 545
 546 Wed Sep 28 12:17:50 1994  Robert Joop  (rj@rainbow.in-berlin.de)
 547
 548         * c++_lib/inc/asn_buf.h: fixed both Copy()'s name and
 549         implementation to CopyOut() that always returns the number of
 550         bytes copied out instead of 0 in case less than the requested
 551         amount is available.
 552
 553 Sat Sep 17 20:07:29 1994  Robert Joop  (rj@rainbow.in-berlin.de)
 554
 555         * compiler/back_ends/c++_gen/gen_c++_code.c: reordered the
 556         functions to get rid of their annoying declarations.
 557
 558 Wed Sep 14 00:59:36 1994  Robert Joop  (rj@rainbow.in-berlin.de)
 559
 560         * the constructors should initialize all pointers or else the
 561         destructor may delete bogus pointers.
 562
 563         * c_lib/inc/asn_list.h: is unwise to #define unbalanced if()s!
 564
 565         * since i was still irritated by cpp standing for c++ and not the
 566         C preprocessor, i renamed them to cxx (which is one known suffix
 567         for C++ source files). since the standard #define is __cplusplus,
 568         cplusplus would have been the more obvious choice, but it is a
 569         little too long.
 570
 571         * made Print() const (and some other, mainly comparison functions).
 572
 573 Thu Sep  1 01:11:17 1994  Robert Joop  (rj@rainbow.in-berlin.de)
 574
 575         * compiler/core/snacc_config.h dissolved into mem.h and
 576         snacc_util.h.
 577
 578         * the empty statement in a
 579             for (...; ...; ...);
 580           has often been overseen; the equivalent
 581             for (...; ...; ...)
 582               ;
 583           has proven to be less error prone.
 584
 585         * off-topic: cvs and rcs fixed to recognize .C and .asn1 as
 586         suffices for C++ and ASN.1 code, respectively.
 587
 588 Wed Aug 31 00:03:22 1994  Robert Joop  (rj@rainbow.in-berlin.de)
 589
 590         * it is a good idea to have every .c file include its
 591         corresponding .h file were its functions are declared, because
 592         it's a very effictive way to let an ANSI compiler assert that
 593         every function is defined with the same number and types of
 594         arguments as it is declared with. proof: ParseValues() was
 595         declared different than defined (different return type and
 596         arguments reversed).
 597
 598         * for reasons unknown, the compiler files included two of the
 599         various almost identical config.h files.
 600
 601         * compiler/back_ends/c++_gen/gen_c++_code.c: turned the huge
 602         inline funtions into normal functions. (the change was actually
 603         made by IBM ENC, but wasn't properly marked.) due to their size,
 604         these inlines wouldn't get inlined anyway. due to their size they
 605         wouldn't offer any speed advantage (the function call overhead
 606         diminishes). instead, the compiler generated static functions in
 607         every .C file were the .h file is included!  this inflates the .o
 608         files and executables real quick (i'm speaking of MBytes per
 609         executable).
 610
 611         * integrating c{,++}_examples:
 612         .../simple: test csh-script integrated into makefile.
 613
 614 Mon Aug 29 11:18:11 1994  Robert Joop  (rj@rainbow.in-berlin.de)
 615
 616         * the dependencies have been moved into a separate file that is
 617         not under cvs control. otherwise, the makefiles would inflate the
 618         repository unnecessarily.
 619
 620 Sun Aug 28 11:18:23 1994  Robert Joop  (rj@rainbow.in-berlin.de)
 621
 622         * config.h defines TRUE/FALSE for C only. for C++, the built-in
 623         bool type accompanied by true/false is used. for C++ compilers
 624         that don't have bool built-in, an equivalent enum is defined.
 625
 626         * merged .../tbl_{lib,include}/ with .../c_lib/. changes detected
 627         were:
 628         - asn_any.h present in c_lib only.
 629         - asn_bits.c ...
 630         - tbl_*/asn_len.[ch] has an additional function PeekEoc().
 631         - tbl_include/asn_list.h has an additonal macro
 632           FOR_REST_LIST_ELMT_RVS() and three additional functions,
 633           GetAsnListElmtIndex(), AsnListFree() and GetAsnListElmt().
 634           tbl_lib/asn_list.c defines only one additional function,
 635           GetAsnListElmt().
 636         - asn_oid.h has the same extension as the compiler version.
 637         - asn_real.c: the tbl version at two places has
 638             exponent >>= 8;
 639           where the c_lib has
 640             exponent >> 8;
 641           since the latter is a statement without any effect, that's
 642           probably the buggy version...
 643         - tbl_*/asn_tag.[hc]: two additional macros, CONSIFY() and
 644           DECONSIFY(), and an additional function, PeekTag().
 645         - asn_useful.c: the c_lib version contains two dozen used
 646           variables, so why not use the tbl version?
 647         - exp_buf.h ...
 648         - files only found in tbl_include: gen_buf.h,
 649           tbl{,_dec,_enc,_free,_gen_c_hdr,_incl,_print,_util}.h.
 650         - files only found in tbl_lib: gen_buf.c,
 651           tbl{,_dec,_enc,_free,_print,_util}.c.
 652         - sbuf.[hc]: tbl uses functions, c_lib defines cpp macros.
 653
 654         * modified the makefiles to include depend, install, clean and
 655         clobber phony targets following the usual conventions.
 656
 657         * INSTALL, mkinstalldirs and install.sh copied from autoconf-1.11.
 658
 659         * 1.0-to-1.1-changes renamed to NEWS. README.changes that starts
 660         with a line reading ``Changes between 1.0 and 1.1'' merged into NEWS.
 661
 662         * collected common code from compiler/core/snacc_config.h,
 663         c_lib/inc/asn_config.h and c++_lib/inc/asn_config.h into config.h.bot.
 664
 665         * adding support for configuration via GNU autoconf:
 666         - writing a configure.in, acconfig.h, makehead.in.
 667         - replace a lot of macros in the makefiles with an inclusion of a
 668           makehead file generated by configure. since file inclusion has
 669           been a feature supported since UNIX System III, i consider it
 670           pretty portable.
 671
 672         * first cvs import.
 673
 674         * inserting RCS keywords as a preparation for cvs import.
 675
 676 Sat Aug 27 11:59:08 1994  Robert Joop  (rj@rainbow.in-berlin.de)
 677
 678         * fixed the developer's nightmare that for every tiny change,
 679         virtually everything was remade.
 680
 681         * -DFLEX ain't necessary since flex defines FLEX_SCANNER already.
 682
 683         * renamed asn1.lex to lex-asn1.l and asn1.yacc to parse-asn1.y to
 684         take advantage of make's default rules.
 685
 686         * collision of #define Free() in the compiler's mem.h and a member
 687         called Free in c_lib's struct AnyInfo in asn_any.h resolved.

 689         * changed the directory structure. the content of .../c_lib/ +
 690         .../c_include/ was almost identical to that of .../src/c_lib/, so
 691         i merged them. .../src/ isn't the only directory containing
 692         source, so i renamed it to compiler.  to sum it up:
 693
 694         old:                    new:
 695         .../src/back_ends       .../compiler/back_ends
 696         .../src                 .../compiler/core
 697         .../src/c_lib                   -> merged with .../c_{lib,include}
 698         .../c_lib               .../c_lib/src
 699         .../c_include           .../c_lib/inc
 700         .../c++_lib             .../c++_lib/src
 701         .../c++_include         .../c++_lib/inc
 702
 703         the differences found between .../src/c_lib/ and
 704         .../c_{lib,include}/:
 705         - Malloc()/Free() vs. NibbleAlloc()
 706         - snacc_config.h partially copied to asn_config.h
 707         - for the compiler, struct OID in asn_oid.h contains an additional
 708           member.
 709         - the functions AsnListConcat(), AsnListFree() and
 710           GetAsnListElmtIndex() existed in the compiler version only.
 711           the mixture of Asn1Alloc() in combination with Free() and free()
 712           has been unified to using Asn1Free().
 713
 714         yet another almost identical copy of c_lib/ can be found in
 715         .../tbl_{lib,include}/.
 716
 717         * since the code was quite inconsistent in respect of where lines
 718         were broken (many short lines that unbroken are shorter than 72
 719         columns were broken, and many long lines were broken into pieces
 720         that were much longer than 80 columns), i took the liberty to
 721         unify the layout.
 722
 723         * some international rules of typography:
 724         - put a space before an opening parenthesis, and one after a
 725           closing one.
 726         - no space after an opening parenthesis, or before a closing one.
 727         - no space before punctuation.
 728         - one space after punctuation (in some countries two after a full
 729           stop).
 730
 731         * a space somewhere between function name and first argument helps
 732         to see that there are actually two words, not just one. for me,
 733           AlongFunctionName(andanArgument, ...)
 734         looks too much like
 735           AlongFunctionNameCandanArgument, ...)
 736         and thus i prefer
 737           AlongFunctionName (andanArgument, ...)
 738
 739         * moved `*' and `&' from the type to the value. that's where C and
 740         C++ bind them to!  people are often mislead by this and generate
 741         bugs like
 742           char* p1, p2;
 743         instead of
 744           char *p1, *p2;
 745         which they really meant. blame K&R, not me :-)
 746
 747         * removed trailing blank lines. they simply produce blank pages
 748         when the file is printed out. some files had got a dozen of them!
 749
 750         * trailing white space removed. noted here because it might cause
 751         problems when someone wants to integrate patches; but vi users
 752         hate empty lines that aren't empty because of white space, since
 753         it keeps some movement commands from working.
 754
 755         * one of IBM ENC's changes is the addition of C++ destructors.
 756         this change was clearly marked and therefore i removed the
 757         #defines.
 758
 759         * i took the official snacc-1.1 distribution and made a diff(1) to
 760         another version modified by IBM ENC. this diff has been merged
 761         with the official version using `patch -D _IBM_ENC_`.
