494--------------- 495 496* All .fas files generated by previous CLISP versions are invalid and 497 must be recompiled. This is because the Just-In-Time Compiled code is 498 kept with the closures. 499 Set CUSTOM:*LOAD-OBSOLETE-ACTION* to :COMPILE to automate this. 500 See <http://clisp.org/impnotes/loadfile.html> for details. 501 502User visible changes 503-------------------- 504 505* The top-level configure option --build has been replaced by --cbc 506 (Configure/Build/Check) to avoid conflict with the standard autoconf option. 507 508* Experimental Just-In-Time Compilation of byte-compiled closures is now 509 done using GNU lightning (this is a configure-time option). 510 Thanks to Yann Dauphin <yann-nicolas.dauphin@polymtl.ca>. 511 512* New command-line option -lp adds directories to *LOAD-PATHS*. 513 See <http://clisp.org/impnotes/clisp.html#opt-load-paths> for details. 514 515* New function FFI:OPEN-FOREIGN-LIBRARY allows pre-opening of shared libraries. 516 See <http://clisp.org/impnotes/dffi.html#dffi-open-lib> for details. 517 518* New macro EXT:COMPILE-TIME-VALUE allows computing values at file compilation. 519 See <http://clisp.org/impnotes/macros3.html#compile-time-value> for details. 520 521* New function FFI:FOREIGN-POINTER-INFO allows some introspection. 522 See <http://clisp.org/impnotes/dffi.html#fptr-info> for details. 523 524* Versioned library symbols are now accessible via the :VERSION argument of 525 DEF-CALL-OUT and DEF-C-VAR. 526 Thanks to Kaz Kylheku <kkylheku@gmail.com>. 527 See <http://clisp.org/impnotes/dffi.html#def-call-out> for details. 528 529* New functions GRAY:STREAM-READ-SEQUENCE and GRAY:STREAM-WRITE-SEQUENCE have 530 been added for portability reasons. 531 Suggested by Anton Vodonosov <avodonosov@yandex.ru>. 532 See <http://clisp.org/impnotes/gray.html#st-rd-seq> for details. 533 534* New user variable CUSTOM:*SUPPRESS-SIMILAR-CONSTANT-REDEFINITION-WARNING* 535 controls whether the redefinition warning is issues when the new 536 constant value is visually similar to the old one. 537 See <http://clisp.org/impnotes/defconstant.html#defconstant-similar> 538 for details. 539 540* REPL commands can now accept arguments. 541 See <http://clisp.org/impnotes/repl.html> for details. 542 543* Updated the postgresql module to PostgreSQL 8.3. 544 See <http://clisp.org/impnotes/postgresql.html> for details. 545 546* Module syscalls now interfaces to <stdio.h> (for the sake of FFI modules). 547 See <http://clisp.org/impnotes/syscalls.html#stdio> for details. 548 There are others additions there also, but they are too numerous to 549 be enumerated here. 550 551* Bug fixes: 552 + Fix handling of quoted objects by READ-PRESERVING-WHITESPACE (bug#445). 553 + Fix rectangle count in NEW-CLX XLIB:SET-GCONTEXT-CLIP-MASK (bug#index.php?func=detail&aid=1918017&group_id=1355&atid=101355). 554 + Fix argument handling in NEW-CLX XLIB:QUERY-COLORS (bug#461). 555 + Fix compilation on systems not supporting returning void (bug#449). 556 + Fix TANH floating point overflow for large floats (bug#407). 557 + Avoid extra aggressive bignum overflow reporting in READ (bug#455). 558 + Improved floating point number formatting. (bug#419, bug#456) 559 + COMPILE no longer discards MACRO doc strings (bug#465). 560 + Improved accuracy of LOG on complex numbers (bug#463). 561 + Fix COERCE for compound float result-types (bug#467). 562 + Fix $http_proxy parsing (bug#471). 563 + Fix LISTEN on buffered streams when the last character was 564 CRLF (bug#472). 565 + Cross-compilation process has been restored to its former glory, 566 thanks to the valiant and persistent testing by 567 Vladimir Volovich <vvv2@users.sourceforge.net>. 568 (bug#457, bug#458, bug#459, bug#460) 569 570 5712.44.1 (2008-02-23) 572=================== 573 574User visible changes 575-------------------- 576 577* Bug fixes: 578 + Add a workaround against a gcc 4.2.x bug (bug#428). 579 + Fix error in compilation of floatparam.c during configuration with gcc 4.3 580 snapshots (bug#428). 581 582 5832.44 (2008-02-02) 584================= 585 586User visible changes 587-------------------- 588 589* CLISP does not come with GNU libffcall anymore. 590 This is now a separate package and should be installed separately. 591 Pass --with-libffcall-prefix to the top-level configure if it is not 592 installed in a standard place. 593 Option --with-dynamic-ffi is now replaced with --with-ffcall. 594 595* CLOS now issues warnings of type CLOS:CLOS-WARNING. 596 See <http://clisp.org/impnotes/mop-clisp.html#mop-clisp-warn> 597 for details. 598 599* The AFFI (simple ffi, originally for Amiga) code has been removed. 600 601* Speed up list and sequence functions when :TEST is EQ, EQL, EQUAL or EQUALP. 602 603* Rename EXT:DELETE-DIR, EXT:MAKE-DIR, and EXT:RENAME-DIR to 604 EXT:DELETE-DIRECTORY, EXT:MAKE-DIRECTORY, and EXT:RENAME-DIRECTORY, 605 respectively, for consistency with EXT:PROBE-DIRECTORY, 606 EXT:DEFAULT-DIRECTORY and CL:PATHNAME-DIRECTORY. 607 The old names are still available, but deprecated. 608 609* The :VERBOSE argument to SAVEINITMEM defaults to a new user variable 610 *SAVEINITMEM-VERBOSE*, initial value T. 611 See <http://clisp.org/impnotes/image.html> for details. 612 613* Bug fixes: 614 + Fix FRESH-LINE at the end of a line containing only TABs (bug#426). 615 + PPRINT-LOGICAL-BLOCK no longer ignores 616 *PRINT-PPRINT-DISPATCH-TABLE* (bug#427). 617 + BYTE is now a full-fledged type (bug#433). 618 + Fix linux:dirent definition in the bindings/glibc module (bug#417). 619 + Symbolic links into non-existent directories can now be 620 deleted (bug#435). 621 + DIRECTORY :FULL on directories now returns the same information as 622 on files (bug#436). 623 + CLISP no longer hangs at the end of a script coming via a pipe 624 ("clisp < script.lisp" or "cat script | clisp") (bug#437). 625 + When *CURRENT-LANGUAGE* is incompatible with *TERMINAL-ENCODING*, 626 CLISP no longer goes into an infinite recursion trying to print 627 various help messages (bug#438). 628 + Fix the "Quit" debugger command (bug#327). 629 + Repeated terminating signals kill CLISP instantly with the correct 630 exit code (bug#441). 631 + Stack inspection is now safer (bug#347). 632 + Errors in the RC-file and init files are now handled properly (bug#411). 633 + Avoid the growth of the restart set with each image save (bug#443). 634 + Handle foreign functions coming from the old image which cannot be 635 validated (bug#310). 636 + Fix signal code in bindings/glibc/linux.lisp (bug#418). 637 638 6392.43 (2007-11-18) 640================= 641 642User visible changes 643-------------------- 644 645* Infrastructure: 646 + Top-level configure now accepts a new option --vimdir which specifies 647 the installation directory for the VIM files (lisp.vim). 648 The default value is ${datadir}/vim/vimfiles/after/syntax/. 649 Thus, lisp.vim is now installed by "make install", and should 650 be included in the 3rd party distributions. 651 + Top-level configure now always runs makemake, and makemake no longer is 652 a "user-level" command; do not run it unless you know what you are doing. 653 This brings the CLISP build process in compliance with the GNU standards. 654 + We now use gnulib-tool to sync with gnulib (not really user visible, 655 but a major infrastructure change). 656 657* Portability: 658 + Support for ancient systems with broken CPP have been dropped. 659 This includes AIX 4.2, Coherent386, Ultrix, MSVC4, MSVC5. 660 + NeXT application (GUI) code has been removed. Plain TTY is still supported. 661 662* Module Berkeley-DB now supports Berkeley DB 4.5 & 4.6. 663 664* Bug fixes: 665 + FORCE-OUTPUT breakage on MacOS X when stdout is not a terminal (bug#421). 666 + Fixed *PRINT-PPRINT-DISPATCH* binding in WITH-STANDARD-IO-SYNTAX (bug#425). 667 668 6692.42 (2007-10-16) 670================= 671 672User visible changes 673-------------------- 674 675* New module gtk2 interfaces to GTK+ v2 and makes it possible to build 676 GUI with Glade. 677 Thanks to James Bailey <dgym.bailey@gmail.com> for the original code. 678 See <http://clisp.org/impnotes/gtk.html> for details. 679 680* New module gdbm interfaces to GNU DataBase Manager. 681 Thanks to Masayuki Onjo <masayuki.onjo@gmail.com>. 682 See <http://clisp.org/impnotes/gdbm.html> for details. 683 684* A kind of Meta-Object Protocol for structures is now available. 685 See <http://clisp.org/impnotes/defstruct-mop.html> for details. 686 687* Module libsvm has been upgraded to the upstream version 2.84. 688 See <http://clisp.org/impnotes/libsvm.html> for details. 689 690* NEW-CLX module now supports Stumpwm <http://www.nongnu.org/stumpwm/>. 691 Thanks to Shawn Betts <sabetts@vcn.bc.ca>. 692 New NEW-CLX demos: bball bwindow greynetic hanoi petal plaid recurrence from 693 <http://www.cs.cmu.edu/afs/cs/project/ai-repository/ai/lang/lisp/gui/clx/clx_demo.cl>. 694 New NEW-CLX demo: clclock based on <http://common-lisp.net/~crhodes/clx>. 695 New function XLIB:OPEN-DEFAULT-DISPLAY from portable CLX. 696 697* Function EXT:ARGLIST now works on macros too. 698 See <http://clisp.org/impnotes/evaluation.html#arglist> for details. 699 700* Macro TRACE has a new option :BINDINGS, which is useful to share data 701 between PRE-* and POST-* forms. 702 See <http://clisp.org/impnotes/debugger.html#trace> for details. 703 704* Macro FFI:DEF-C-TYPE can now be called with one argument to define an 705 integer type. 706 See <http://clisp.org/impnotes/dffi.html#def-c-type> for details. 707 708* New function EXT:RENAME-DIR can be used to rename directories. 709 See <http://clisp.org/impnotes/dir-func.html#rename-dir> for details. 710 711* Functions FILE-LENGTH and FILE-POSITION now work on unbuffered streams too. 712 See <http://clisp.org/impnotes/file-pos.html> for details. 713 714* Bug fixes: 715 + Fixed EXT:LETF to work with more than one place (bug#413). 716 + Fixed rounding of long floats [even+1/2] (bug#376). 717 + Fixed stdio when running without a TTY, e.g., under SSH (bug#378). 718 + ANSI compliance: PPRINT dispatch is now respected for nested 719 objects, not just the top-level (bug#339, bug#382). 720 + Fixed print-read-consistency of strings containing #\Return characters 721 (manifested by COMPILE-FILE) (bug#373). 722 + Fixed "clisp-link run" (bug#332). 723 + Fixed ATANH branch cut continuity (bug#324). 724 + Reset the function lambda expression when loading a compiled 725 file (bug#383). 726 + DOCUMENTATION set by SETF is now preserved by COMPILE (bug#384). 727 + LISTEN now calls STREAM-LISTEN as per the Gray proposal (bug#387). 728 + IMPORT into the KEYWORD package does not make a symbol a constant 729 variable (bug#391). 730 + DEFPACKAGE code was executed during non top-level compilation (bug#389). 731 + Fixed format error message formatting (bug#336). 732 + Fixed *PPRINT-FIRST-NEWLINE* handling (bug#314). 733 + Improved hash code generation for very large bignums and for long lists 734 (bug#208, bug#255). 735 + Some bugs related to UNICODE-16 & UNICODE-32 (bug#366, 736 bug#399, bug#400). 737 + All exported defined symbols are now properly locked (bug#410). 738 + Berkeley-DB module no longer fills up error log file (bug#416). 739 + New-clx now supports 64-bit KeySym (bug#420). 740 741 7422.41 (2006-10-13) 743================= 744 745User visible changes 746-------------------- 747 748* New module libsvm interfaces to <http://www.csie.ntu.edu.tw/~cjlin/libsvm> 749 and makes Support Vector Machines available in CLISP. 750 See <http://clisp.org/impnotes/libsvm.html> for details. 751 752* FASTCGI:GETENV is now compatible with EXT:GETENV and can return the 753 entire environment as an alist. 754 755* The same internal interface now handles FFI forms DEF-CALL-OUT and 756 DEF-C-VAR regardless of the presence of the :LIBRARY argument. 757 (:LIBRARY NIL) is now identical to omitting the :LIBRARY argument. 758 The default for the :LIBRARY argument is set by 759 FFI:DEFAULT-FOREIGN-LIBRARY per compilation unit. 760 See <http://clisp.org/impnotes/dffi.html#dffi-default-lib> for details. 761 762* Bug fixes: 763 + DOCUMENTATION on built-in functions was broken on some 764 platforms (bug#369). 765 + Fixed FFI callbacks, broken since the 2.36 release. 766 + Fixed the way the top-level driver handles the "--" option terminator. 767 + Fixed COMPILE of APPLY in LABELS for local function (bug#372). 768 769 7702.40 (2006-09-23) 771================= 772 773Important notes 774--------------- 775 776* All .fas files generated by previous CLISP versions are invalid and 777 must be recompiled. This is because DOCUMENTATION and LAMBDA-LIST are 778 now kept with the closures. 779 Set CUSTOM:*LOAD-OBSOLETE-ACTION* to :COMPILE to automate this. 780 See <http://clisp.org/impnotes/loadfile.html> for details. 781 782User visible changes 783-------------------- 784 785* Infrastructure 786 + Top-level configure now accepts a new option --elispdir which specifies 787 the installation directory for the Emacs Lisp files (clhs.el et al). 788 The default value is ${datadir}/emacs/site-lisp/. 789 Thus, clhs.el at al are now installed by "make install", and should 790 be included in the 3rd party distributions. 791 + Top-level configure now accepts variables on command line, e.g., 792 ./configure CC=g++ CFLAGS=-g 793 794* Function PCRE:PCRE-EXEC accepts :DFA and calls pcre_dfa_exec() when 795 built against PCRE v6. See <http://clisp.org/impnotes/pcre.html>. 796 797* New functions RAWSOCK:IF-NAME-INDEX, RAWSOCK:IFADDRS. 798 See <http://clisp.org/impnotes/rawsock.html>. 799 800* When the OPTIMIZE SPACE level is low enough, keep function 801 documentation and lambda list. 802 See <http://clisp.org/impnotes/declarations.html#space-decl>. 803 804* Bug fixes: 805 + Make it possible to set *IMPNOTES-ROOT-DEFAULT* and *CLHS-ROOT-DEFAULT* 806 to local paths, as opposed to URLs (bug#344). 807 + Fix the evaluation order of initialization and :INITIALLY forms in 808 then extended LOOP (bug#351). 809 + Do not allow non-symbols as names of anonymous classes (bug#354). 810 + REINITIALIZE-INSTANCE now calls FINALIZE-INHERITANCE (bug#353). 811 + Fix the RAWSOCK module on big-endian platforms (bug#355). 812 + PRINT-OBJECT now works on built-in objects (bug#337). 813 + ADJUST-ARRAY signals an error if :FILL-POINTER is supplied and non-NIL 814 but the non-adjustable array has no fill pointer, as per ANSI (bug#360). 815 + MAKE-PATHNAME no longer ignores explicit :DIRECTORY NIL (thanks to 816 Stephen Compall <s11001001@users.sourceforge.net>) (bug#363). 817 + Executable images now work on ia64 (thanks to Dr. Werner Fink 818 <werner@suse.de>). 819 + MAKE-PATHNAME on win32 now handles correctly directories that start 820 with a non-string (e.g., :WILD) (bug#364). 821 + SOCKET-STREAM-PEER and SOCKET-STREAM-LOCAL had do-not-resolve-p 822 inverted since 2.37. 823 + Set functions with :TEST 'EQUALP were broken on large lists (bug#368). 824 825 8262.39 (2006-07-16) 827================= 828 829User visible changes 830-------------------- 831 832* SAVEINITMEM now accepts :SCRIPT argument that disables interpreting 833 the first positional argument as the script name; and :DOCUMENTATION 834 argument that is printed by the new -help-image command line option. 835 See <http://clisp.org/impnotes/image.html> and 836 <http://clisp.org/impnotes/clisp.html#opt-help-image> for details. 837 838* FFI:UINT64 and FFI:SINT64 are now compatible with C's long long type. 839 840* Stack overflow detection and recovery finally work fine on Unix. 841 Libsigsegv is required for this, on all platforms (including MS-Windows). 842 CLISP should neither exit nor crash under infinite recursion. 843 If your distribution has CLISP compiled without libsigsegv, report 844 the missing feature to its maintainer. 845 Note that libsigsegv 2.4 is required, there are bugs in libsigsegv 2.3! 846 847* It is now possible to specify the default method-combination of a generic 848 function, to be used when the DEFGENERIC form does not specify the 849 :METHOD-COMBINATION explicitly, through a default initarg specification 850 for the :METHOD-COMBINATION keyword on the generic function class. 851 852* Readline completion works with non 1:1 terminal encodings, e.g. UTF-8. 853 854* WITH-KEYBOARD works with the terminal even when SLIME hijacks *TERMINAL-IO*. 855 856* I/O operations on Win32 are now much faster. 857 858* New functions: POSIX:FFS, POSIX:PATHCONF. 859 860* Infrastructure: 861 + Top-level configure now accepts a new option --with-gmalloc to use the 862 GNU malloc implementation instead of the one supplied by libc. 863 You may need it on older HP-UX and newer OpenBSD systems. 864 See file unix/PLATFORMS for more information. 865 + The value of the environment variable CFLAGS is respected by configure. 866 867* Bug fixes: 868 + SOCKET:SOCKET-SERVER :INTERFACE now behaves as documented. 869 + EXT:READ-BYTE-NO-HANG and SOCKET:SOCKET-STATUS used to hang on 870 buffered binary sockets. 871 + Allow DESTRUCTURING-BIND (a . b) with circular and dotted lists. 872 + ADJUST-ARRAY of zero length adjustable string now works. 873 + TIME now reports correct results when the heap grows over 4GB. 874 + RAWSOCK functions now handle :START/:END arguments correctly. 875 + BDB:DBC-GET now accepts :READ-COMMITTED and :READ-UNCOMMITTED. 876 + POSIX:GROUP-INFO and POSIX:USER-INFO now handle errors correctly. 877 878* Portability: 879 + Support DragonFly BSD. 880 881 8822.38 (2006-01-24) 883================= 884 885User visible changes 886-------------------- 887 888* SAVEINITMEM can create standalone executables. 889 Thanks to Frank Buß <fb@frank-buss.de> for the idea. 890 SAVEINITMEM also accepts :NORC argument to disable RC-file loading. 891 See <http://clisp.org/impnotes/image.html> for details. 892 893* POSIX:SYSLOG no longer recognizes "%m" and other formatting instructions. 894 For your safety and security, please do all formatting in Lisp. 895 896* Fixed the OPEN :IF-EXISTS :APPEND bug introduced in 2.37. 897 898* Fixed a crash on woe32 in opening files with names longer than MAX_PATH. 899 900* Module Berkeley-DB now supports Berkeley DB 4.4. 901 902 9032.37 (2006-01-02) 904================= 905 906User visible changes 907-------------------- 908 909* Signal a continuable error when an already opened file is opened again, 910 unless both streams are read-only. 911 912* SOCKET-SERVER now accepts :BACKLOG and :INTERFACE arguments. 913 The first (optional) argument should be the port number or NIL. 914 Use (SOCKET-SERVER NIL :INTERFACE SOCKET) instead of (SOCKET-SERVER SOCKET). 915 Thanks to Tomas Zellerin <zellerin@gmail.com>. 916 See <http://clisp.org/impnotes/socket.html#sose> for details. 917 918* EXT:HTTP-PROXY now uses the environment variable "http_proxy", like 919 curl does, not "HTTP_PROXY", to avoid confusing it with CGI arguments. 920 921* OPEN :DIRECTION :OUTPUT now creates write-only handles and treats 922 named pipes correctly. 923 924* Fixed EXT:SETENV on non-POSIX systems (woe32 and BSD derivatives). 925 926* Fixed a bug in EXT:! on 64-bit platforms. 927 Thanks to Dr. Werner Fink <werner@suse.de>. 928 929 9302.36 (2005-12-04) 931================= 932 933User visible changes 934-------------------- 935 936* Infrastructure: 937 + Top-level configure now accepts the option --enable-maintainer-mode 938 that affects autoconf-related Makefile targets. The default value 939 is determined based on the presence of the CVS directories. 940 + When libsigsegv is not found, print instructions on getting/building 941 libsigsegv and bail out; override with --ignore-absence-of-libsigsegv. 942 + When --with-dynamic-ffi is supplied, but the FFI fails to build, abort. 943 + When --with-readline is supplied, but GNU readline is not found, abort. 944 + makemake no longer checks with_module_* variables. 945 946* New function EXT:OPEN-HTTP and macro EXT:WITH-HTTP-INPUT. 947 See <http://clisp.org/impnotes/macros3.html#open-http> for details. 948 949* New declaration EXT:NOTSPECIAL undoes the effects of DEFVAR and DEFCONSTANT. 950 See <http://clisp.org/impnotes/declarations.html#notspec-decl> 951 for details. 952 953* Function EXT:CLHS is now deprecated in favor of DESCRIBE, which can now 954 point your web browser to the ANSI CL and CLISP-specific documentation. 955 See <http://clisp.org/impnotes/debugger.html#describe> 956 for details. 957 958* FFI modules can now take advantage of autoconf feature detection. 959 See <http://clisp.org/impnotes/dffi.html#ffi-guard> for details. 960 961* New FFI macro FFI:DEF-C-CONST. 962 See <http://clisp.org/impnotes/dffi.html#def-c-const> for details. 963 964* New charset BASE64 encodes arbitrary byte sequences with strings of 965 printable ASCII characters (4 characters per 3 bytes). 966 See <http://clisp.org/impnotes/encoding.html#base64> for details. 967 968* New module readline offers some advanced readline and history features. 969 It is a BASE module and is available when both FFI and readline are present. 970 971* SOCKET:SOCKET-SERVICE-PORT is now deprecated in favor of OS:SERVICE. 972 See <http://clisp.org/impnotes/syscalls.html#service> for details. 973 974* New SETF-able functions POSIX:GETUID, POSIX:GETGID, POSIX:GETEUID, 975 POSIX:GETEGID. 976 New functions POSIX:GROUP-INFO and POSIX:STRING-TIME. 977 Function POSIX:USER-DATA is renamed to POSIX:USER-INFO. 978 See <http://clisp.org/impnotes/syscalls.html> for details. 979 980* New NEW-CLX demo: koch.lisp draws fractal snowflakes. 981 Implemented XLIB:SET-MODIFIER-MAPPING, XLIB:KEYSYM->KEYCODES, 982 XLIB:ACCESS-HOSTS, XLIB:ADD-ACCESS-HOST, XLIB:REMOVE-ACCESS-HOST, 983 XLIB:CHANGE-KEYBOARD-CONTROL, XLIB:CHANGE-KEYBOARD-MAPPING, 984 XLIB:KEYBOARD-MAPPING, XLIB:KEYSYM-NAME, XLIB:KEYCODE->CHARACTER, 985 XLIB:SHAPE-EXTENTS, XLIB:SHAPE-RECTANGLES, XLIB:DEFAULT-KEYSYM-INDEX. 986 Use MAP instead of ELT for sequence access in NEW-CLX. 987 988* ANSI CL compliance issues: 989 + DEFPACKAGE options :SHADOWING-IMPORT-FROM, :USE, :IMPORT-FROM 990 accept package designators, not just package names. 991 + ENCODE-UNIVERSAL-TIME is now the perfect inverse for DECODE-UNIVERSAL-TIME. 992 993* The command line option -v now affects *LOAD-ECHO* also. 994 See <http://clisp.org/impnotes/clisp.html#opt-verbose> for details. 995 996* When a CLISP process is killed, clean-up is always executed. 997 998* DEFCLASS now permits user-defined :ALLOCATION arguments. 999 1000* Fixed (FUNCTION-LAMBDA-EXPRESSION #'(SETF FOO)) on compiled functions. 1001 1002* Fixed re-exporting symbols from POSIX to EXT. 1003 1004* Fixed module rawsock on platforms with non-trivial struct sockaddr layout. 1005 Functions that take a BUFFER argument, also take :START and :END arguments. 1006 Renamed RAWSOCK:LISTEN to RAWSOCK:SOCK-LISTEN to avoid a conflict with CL. 1007 New functions RAWSOCK:PROTOCOL, RAWSOCK:NETWORK, RAWSOCK:GETADDRINFO, 1008 RAWSOCK:GETNAMEINFO. 1009 See <http://clisp.org/impnotes/rawsock.html> for details. 1010 1011* Fixed module postgresql logging behavior. 1012 1013* Fixed clisp.h generation to conform to the internal definitions. 1014 1015 10162.35 (2005-08-29) 1017================= 1018 1019User visible changes 1020-------------------- 1021 1022* SOCKET:SOCKET-STREAM-SHUTDOWN does not call CLOSE anymore, 1023 just shutdown(2) - as it has always been documented. 1024 It now also works on raw sockets, thus RAWSOCK:SHUTDOWN has been removed. 1025 See <http://clisp.org/impnotes/socket.html#sost-shut> and 1026 <http://clisp.org/impnotes/rawsock.html> for details. 1027 1028* When the command line option -E receives an invalid encoding, 1029 ISO-8859-1 is used instead. [It was ASCII (for *FOREIGN-ENCODING*) or 1030 UTF-8 (for all other encodings) before.] 1031 Rationale: this is a 1:1 that corresponds to CLISP CODE-CHAR/CHAR-CODE 1032 and avoids spurious errors in DIRECTORY on startup. 1033 1034* New function EXT:COMPILED-FILE-P - checks whether the file is a 1035 CLISP-compiled file with a compatible bytecode format. 1036 See <http://clisp.org/impnotes/compiled-file-p.html> for details. 1037 1038* New functions EXT:CHAR-INVERTCASE, EXT:STRING-INVERTCASE and 1039 EXT:NSTRING-INVERTCASE invert case of characters and strings. 1040 See <http://clisp.org/impnotes/char-case.html#char-invertcase> and 1041 <http://clisp.org/impnotes/string-misc.html#string-invertcase> for details. 1042 1043* New function POSIX:STREAM-OPTIONS calls fcntl(2). 1044 See <http://clisp.org/impnotes/syscalls.html#fcntl> for details. 1045 1046* Explicitly close all possible file descriptors before exec(). 1047 1048* Danish translations of the user interface messages have been added. 1049 Thanks to Dennis Decker Jensen <dennisdjensen@tiscali.dk>. 1050 1051 10522.34 (2005-07-20) 1053================= 1054 1055Important notes 1056--------------- 1057 1058* All .fas files generated by previous CLISP versions are invalid and 1059 must be recompiled. This is caused by the addition of MOP, the DEFSETF 1060 fixes, and the TRANSLATE-PATHNAME and MAKE-HASH-TABLE enhancements. 1061 Set CUSTOM:*LOAD-OBSOLETE-ACTION* to :COMPILE to automate this. 1062 See <http://clisp.org/impnotes/loadfile.html> for details. 1063 1064* The name of the Run-Control file has changed from '_clisprc' to 1065 '.clisprc' on all platforms. 1066 If you are using woe32, please rename your Run-Control file. 1067 1068* Modules i18n, regexp, and syscalls are now present even in the base 1069 linking set. Do not pass, e.g., "--with-module=regexp" to configure. 1070 1071User visible changes 1072-------------------- 1073 1074* The CLOS MetaObject Protocol is supported: 1075 + New class METAOBJECT. 1076 + Classes: 1077 New classes 1078 STANDARD-READER-METHOD, STANDARD-WRITER-METHOD, FORWARD-REFERENCED-CLASS. 1079 New functions 1080 ENSURE-CLASS. 1081 New generic functions 1082 CLASS-DIRECT-SUPERCLASSES, CLASS-PRECEDENCE-LIST, CLASS-DIRECT-SLOTS, 1083 CLASS-SLOTS, CLASS-DIRECT-DEFAULT-INITARGS, CLASS-DEFAULT-INITARGS. 1084 New customizable generic functions 1085 For class creation: 1086 ENSURE-CLASS-USING-CLASS, VALIDATE-SUPERCLASS, 1087 COMPUTE-DIRECT-SLOT-DEFINITION-INITARGS, 1088 COMPUTE-CLASS-PRECEDENCE-LIST, COMPUTE-EFFECTIVE-SLOT-DEFINITION, 1089 COMPUTE-EFFECTIVE-SLOT-DEFINITION-INITARGS, COMPUTE-SLOTS, 1090 COMPUTE-DEFAULT-INITARGS, READER-METHOD-CLASS, WRITER-METHOD-CLASS. 1091 For notification about subclasses: 1092 CLASS-DIRECT-SUBCLASSES, ADD-DIRECT-SUBCLASS, REMOVE-DIRECT-SUBCLASS. 1093 + Generic Functions: 1094 New classes 1095 FUNCALLABLE-STANDARD-CLASS, FUNCALLABLE-STANDARD-OBJECT. 1096 New functions 1097 ENSURE-GENERIC-FUNCTION, SET-FUNCALLABLE-INSTANCE-FUNCTION, 1098 COMPUTE-EFFECTIVE-METHOD-AS-FUNCTION. 1099 New generic functions 1100 GENERIC-FUNCTION-NAME, GENERIC-FUNCTION-METHODS, 1101 GENERIC-FUNCTION-METHOD-CLASS, GENERIC-FUNCTION-LAMBDA-LIST, 1102 GENERIC-FUNCTION-METHOD-COMBINATION, 1103 GENERIC-FUNCTION-ARGUMENT-PRECEDENCE-ORDER, GENERIC-FUNCTION-DECLARATIONS. 1104 New customizable generic functions 1105 ENSURE-GENERIC-FUNCTION-USING-CLASS, COMPUTE-DISCRIMINATING-FUNCTION, 1106 COMPUTE-APPLICABLE-METHODS, COMPUTE-APPLICABLE-METHODS-USING-CLASSES. 1107 + Methods: 1108 New generic functions 1109 METHOD-FUNCTION, METHOD-GENERIC-FUNCTION, METHOD-LAMBDA-LIST, 1110 METHOD-SPECIALIZERS, ACCESSOR-METHOD-SLOT-DEFINITION. 1111 New functions 1112 EXTRACT-LAMBDA-LIST, EXTRACT-SPECIALIZER-NAMES. 1113 + Method-Combinations: 1114 New generic function 1115 FIND-METHOD-COMBINATION. 1116 New customizable generic function 1117 COMPUTE-EFFECTIVE-METHOD. 1118 + Slot-Definitions: 1119 New classes 1120 SLOT-DEFINITION, STANDARD-SLOT-DEFINITION, 1121 DIRECT-SLOT-DEFINITION, STANDARD-DIRECT-SLOT-DEFINITION, 1122 EFFECTIVE-SLOT-DEFINITION, STANDARD-EFFECTIVE-SLOT-DEFINITION. 1123 New generic functions 1124 SLOT-DEFINITION-NAME, SLOT-DEFINITION-INITFORM, 1125 SLOT-DEFINITION-INITFUNCTION, SLOT-DEFINITION-TYPE, 1126 SLOT-DEFINITION-ALLOCATION, SLOT-DEFINITION-INITARGS, 1127 SLOT-DEFINITION-READERS, SLOT-DEFINITION-WRITERS, 1128 SLOT-DEFINITION-LOCATION. 1129 New customizable generic functions 1130 DIRECT-SLOT-DEFINITION-CLASS, EFFECTIVE-SLOT-DEFINITION-CLASS. 1131 + Specializers: 1132 New classes 1133 SPECIALIZER, EQL-SPECIALIZER. 1134 New generic functions 1135 SPECIALIZER-DIRECT-GENERIC-FUNCTIONS, SPECIALIZER-DIRECT-METHODS. 1136 New functions 1137 EQL-SPECIALIZER-OBJECT, INTERN-EQL-SPECIALIZER. 1138 New customizable generic functions 1139 ADD-DIRECT-METHOD, REMOVE-DIRECT-METHOD. 1140 + Slot access: 1141 New generic functions 1142 SLOT-VALUE-USING-CLASS, (SETF SLOT-VALUE-USING-CLASS), 1143 SLOT-BOUNDP-USING-CLASS, SLOT-MAKUNBOUND-USING-CLASS. 1144 New functions 1145 STANDARD-INSTANCE-ACCESS, FUNCALLABLE-STANDARD-INSTANCE-ACCESS. 1146 + Dependent object notification: 1147 New functions 1148 MAP-DEPENDENTS. 1149 New customizable generic functions 1150 ADD-DEPENDENT, REMOVE-DEPENDENT, UPDATE-DEPENDENT. 1151 See <http://clisp.org/impnotes/mop-chap.html> for details, 1152 and <http://clisp.org/impnotes/mop-clisp.html> for a list 1153 of differences between CLISP and "The Art of the Metaobject Protocol". 1154 *FEATURES* now contains :MOP. 1155 1156* CLISP now supports programming with case sensitive symbols. This is the 1157 default when CLISP is started with the new command line option "-modern". 1158 See <http://clisp.org/impnotes/package-case.html> and 1159 <http://clisp.org/impnotes/clisp.html#opt-modern> for details. 1160 1161* Several new datatypes that manage weak references: 1162 WEAK-LIST, WEAK-AND-RELATION, WEAK-OR-RELATION, 1163 WEAK-MAPPING, WEAK-AND-MAPPING, WEAK-OR-MAPPING, WEAK-ALIST. 1164 New functions 1165 - for WEAK-LIST: 1166 MAKE-WEAK-LIST, WEAK-LIST-P, WEAK-LIST-LIST, (SETF WEAK-LIST-LIST), 1167 - for WEAK-AND-RELATION: 1168 MAKE-WEAK-AND-RELATION, WEAK-AND-RELATION-P, WEAK-AND-RELATION-LIST, 1169 - for WEAK-OR-RELATION: 1170 MAKE-WEAK-OR-RELATION, WEAK-OR-RELATION-P, WEAK-OR-RELATION-LIST, 1171 - for WEAK-MAPPING: 1172 MAKE-WEAK-MAPPING, WEAK-MAPPING-P, WEAK-MAPPING-PAIR, WEAK-MAPPING-VALUE, 1173 (SETF WEAK-MAPPING-VALUE), 1174 - for WEAK-AND-MAPPING: 1175 MAKE-WEAK-AND-MAPPING, WEAK-AND-MAPPING-P, WEAK-AND-MAPPING-PAIR, 1176 WEAK-AND-MAPPING-VALUE, (SETF WEAK-AND-MAPPING-VALUE), 1177 - for WEAK-OR-MAPPING: 1178 MAKE-WEAK-OR-MAPPING, WEAK-OR-MAPPING-P, WEAK-OR-MAPPING-PAIR, 1179 WEAK-OR-MAPPING-VALUE, (SETF WEAK-OR-MAPPING-VALUE), 1180 - for WEAK-ALIST: 1181 MAKE-WEAK-ALIST, WEAK-ALIST-P, WEAK-ALIST-TYPE, WEAK-ALIST-CONTENTS, 1182 (SETF WEAK-ALIST-CONTENTS), WEAK-ALIST-ASSOC, WEAK-ALIST-RASSOC, 1183 WEAK-ALIST-VALUE, (SETF WEAK-ALIST-VALUE). 1184 See <http://clisp.org/impnotes/weak.html> for details. 1185 1186* You can create formatting streams of class EXT:FILL-STREAM. 1187 See <http://clisp.org/impnotes/fill-stream.html> for details. 1188 1189* SUBTYPEP can determine subtype relationship and type equivalence much better 1190 than it could before. 1191 1192* When *PRINT-READABLY* is true, symbols are now printed with package marker 1193 and vertical bars. 1194 1195* ANSI CL compliance issues: 1196 + Issue <DECLARATION-SCOPE:NO-HOISTING> is implemented: The scope of 1197 declarations that do not apply to bindings, such as free SPECIAL, NOTINLINE 1198 or OPTIMIZE declarations, includes only the body forms and no longer 1199 includes the initforms of the LAMBDA/LET/LET*/MULTIPLE-VALUE-BIND bindings. 1200 + Vectors of element type NIL are now strings in all aspects. But the type 1201 BASE-STRING does _not_ include vectors of element type NIL. 1202 + TYPE-OF now returns STANDARD-CHAR instead of CHARACTER when possible. 1203 + The type COMPILED-FUNCTION no longer encompasses generic functions. 1204 + TYPE-OF now returns COMPILED-FUNCTION or STANDARD-GENERIC-FUNCTION instead 1205 of FUNCTION when possible. 1206 + The space character is printed as "#\ " if CUSTOM:*PRINT-SPACE-CHAR-ANSI* 1207 is true. 1208 + The #<PACKAGE KEYWORD> no longer has the nickname "". The syntax :FOO for 1209 keywords still works, but is now special cased in the reader. 1210 + Class redefinition with DEFCLASS no longer modifies the previous class if 1211 it doesn't have a "proper name". 1212 + Class redefinition with DEFCLASS removes accessor methods that have been 1213 installed through the previous DEFCLASS definition of the same class. 1214 + Generic function redefinition with DEFGENERIC removes methods that have 1215 been installed through the previous DEFGENERIC definition of the same 1216 function. 1217 + The set of qualifiers allowed for methods that are combined with a method 1218 combination defined through the short form of DEFINE-METHOD-COMBINATION 1219 now includes the name of the method combination instead of the operator. 1220 + FIND-METHOD now gives an error if the list of specializers has a wrong 1221 length. 1222 + ARRAY-TOTAL-SIZE-LIMIT, ARRAY-DIMENSION-LIMIT, ARRAY-RANK-LIMIT are now 1223 fixnums. 1224 + SHORT-FLOATs whose absolute value is an integer in the range between 10^5 1225 and 10^7 are now printed with full precision. 1226 + Operations combining rational and floating-point numbers now return a 1227 floating-point result if CUSTOM:*FLOATING-POINT-RATIONAL-CONTAGION-ANSI* 1228 is true. When the mathematical result in a situation is rational, a 1229 warning is issued if CUSTOM:*WARN-ON-FLOATING-POINT-RATIONAL-CONTAGION* is 1230 true. 1231 + Class redefinition with DEFCLASS now updates existing instances as 1232 specified. 1233 + An ABORT restart is now always installed. 1234 + UPDATE-INSTANCE-FOR-DIFFERENT-CLASS does the required argument checking. 1235 + Passing invalid initialization arguments to MAKE-INSTANCE and similar 1236 now generates a PROGRAM-ERROR instead of just an ERROR. 1237 + Documentation strings are now attached to class objects, not just to 1238 their name. 1239 + Arrays with total array size 0 are printed in a lossy way if 1240 CUSTOM:*PRINT-EMPTY-ARRAYS-ANSI* is true and *PRINT-READABLY* is false. 1241 + Allow () to match NIL in destructuring lambda lists. 1242 + Documentation strings at a place where only declarations and forms are 1243 allowed now give a warning, not an error. 1244 + LAST, BUTLAST and NBUTLAST check their list argument for circularity. 1245 + Different LOAD-TIME-VALUE forms that are EQUAL but not EQ are no longer 1246 coalesced by COMPILE-FILE. 1247 + DEFSETF lambda-lists now support &ENVIRONMENT. 1248 + DEFSETF lambda-lists are no longer destructuring lambda-lists. 1249 + NAMESTRING no longer accepts an optional second argument. 1250 + SETF of VALUES now uses only the first value of each subform. 1251 + SPECIAL declarations of variables are now correctly respected inside 1252 macro expanders defined through MACROLET within the declaration's scope. 1253 + (EXPORT NIL), (UNEXPORT NIL), (IMPORT NIL), (SHADOWING-IMPORT NIL), 1254 (SHADOW NIL) are now nops. 1255 + An attempt to create a condition from an invalid condition designator now 1256 always results in a TYPE-ERROR being signalled. 1257 + The reader's errors are now of type READER-ERROR when they should be. 1258 + READ-DELIMITED-LIST now returns NIL when *READ-SUPPRESS* is true. 1259 + Printing of multidimensional arrays now respects *PRINT-LEVEL*. 1260 + As required by 19.2.3, *DEFAULT-PATHNAME-DEFAULTS* is merged into 1261 pathnames before accessing the file system. 1262 + LOGICAL-PATHNAME now gives an error if the argument string does not 1263 contain a host specification. 1264 + The PRINT-UNREADABLE macro prints extraneous spaces if 1265 CUSTOM:*PRINT-UNREADABLE-ANSI* is true. 1266 + In the #n= and #n# reader syntax, the integer n may now be larger than 1267 7 digits. 1268 + IN-PACKAGE forms with constant arguments are no longer executed by the 1269 compiler if they occur in a non-null lexical environment. 1270 + COMPILE-FILE now always returns the TRUENAME of its output file. 1271 + GET-SETF-EXPANSION now accepts NIL as the environment argument to 1272 mean null lexical environment 1273 Thanks to Paul F. Dietz <dietz@dls.net> and his ANSI compliance 1274 suite, which helped detect some of these deficiencies. 1275 Thanks to Yuji Minejima <ggb01164@nifty.ne.jp> and his ANSI compliance 1276 suite, which helped detect some of these deficiencies. 1277 1278* Global error handlers can now be installed and removed using 1279 EXT:SET-GLOBAL-HANDLER, EXT:WITHOUT-GLOBAL-HANDLERS, 1280 and -on-error command line option. 1281 See <http://clisp.org/impnotes/restarts.html#global-handler> and 1282 <http://clisp.org/impnotes/clisp.html#opt-on-error> for details. 1283 1284* TRANSLATE-PATHNAME and TRANSLATE-LOGICAL-PATHNAME accept a new keyword 1285 argument :ABSOLUTE which makes them convert their return values to 1286 absolute pathnames. 1287 See <http://clisp.org/impnotes/filename-misc.html#translate-pathname> and 1288 <http://clisp.org/impnotes/filename-misc.html#translate-logpath> for details. 1289 1290* New function EXT:ABSOLUTE-PATHNAME. 1291 See <http://clisp.org/impnotes/filename-misc.html#absolute-pathname> for details. 1292 1293* New function EXT:ELASTIC-NEWLINE and new FORMAT directive "~.". 1294 See <http://clisp.org/impnotes/elastic-newline.html> 1295 and <http://clisp.org/impnotes/print-formatted.html#format-dot> for details. 1296 Through this function, CLISP no longer produces spurious blank lines when 1297 a program uses the convention of printing a #\Newline before each line. 1298 1299* TRACE has a new option :MAX-DEPTH, that is useful to avoid infinite 1300 recursions in the tracer. 1301 See <http://clisp.org/impnotes/debugger.html#trace> for details. 1302 1303* The function LENGTH and a few other sequence functions now signal a 1304 TYPE-ERROR when a circular list has been given as argument. 1305 1306* Function UPGRADED-COMPLEX-PART-TYPE is now as precise as possible. 1307 See <http://clisp.org/impnotes/num-concepts.html#ucpt> for details. 1308 1309* In non-interactive batch mode, *ERROR-OUTPUT* now uses the system's 1310 standard error stream, instead of the standard output stream. 1311 1312* The macros MUFFLE-CERRORS, APPEASE-CERRORS and EXIT-ON-ERROR now treat 1313 CONTINUE restarts which require interactive user intervention like other 1314 restarts. Only non-interactive CONTINUE restarts are silently invoked. 1315 1316* LOAD :OBSOLETE-ACTION can now also be :COMPILE to automatically 1317 recompile the obsolete *.fas file. 1318 LOAD can now ignore erroneous forms using SKIP and STOP restarts. 1319 See <http://clisp.org/impnotes/loadfile.html> for details. 1320 1321* References from within macros defined through MACROLET to variables or 1322 functions defined in the lexical environment outside the MACROLET form 1323 now signal an error. Previously, this resulted in undefined behavior. 1324 1325* The FFI recognizes the c-type declaration (FFI:C-POINTER <c-type>) to 1326 handle references without conversion to/from Lisp structures. 1327 See <http://clisp.org/impnotes/dffi.html#c-pointer> for details. 1328 1329* The FFI variable FFI:*FOREIGN-ENCODING* can now be a multibyte encoding. 1330 The warning "*FOREIGN-ENCODING*: reset to ASCII" at startup is gone. 1331 1332* New FFI constructor functions FFI:FOREIGN-VARIABLE and FFI:FOREIGN-FUNCTION, 1333 more operators are now exported (FFI:FOREIGN-VALUE, FFI:PARSE-C-TYPE). 1334 See <http://clisp.org/impnotes/dffi.html#dffi-make-var> 1335 and <http://clisp.org/impnotes/dffi.html#dffi-make-func> for details. 1336 1337* FFI macro FFI:C-LINES can now be used to fine-tune 1338 initialization and finalization. 1339 See <http://clisp.org/impnotes/dffi.html#c-lines> for details. 1340 1341* New FFI function FFI:CLOSE-FOREIGN-LIBRARY can be used to unload a library. 1342 See <http://clisp.org/impnotes/dffi.html#dffi-close-lib> for details. 1343 1344* New FFI low-level accessor FFI:MEMORY-AS. 1345 See <http://clisp.org/impnotes/dffi.html#memory-as> for details. 1346 1347* Foreign functions and variables can now be documented using the 1348 :DOCUMENTATION option to FFI:DEF-CALL-OUT and FFI:DEF-C-VAR. 1349 1350* Buffered streams now are suitable for interactive streams. It is no longer 1351 necessary to use :BUFFERED NIL to avoid blocking in various situations. 1352 1353* Function EXT:READ-BYTE-SEQUENCE takes a new keyword argument :INTERACTIVE. 1354 See <http://clisp.org/impnotes/bulk-io.html#rd-by-seq> for details. 1355 1356* Methods on GRAY:STREAM-READ-BYTE-SEQUENCE and GRAY:STREAM-WRITE-BYTE-SEQUENCE 1357 now need to accept a second optional argument. 1358 1359* The possible values of the :WEAK argument of MAKE-HASH-TABLE are changed: 1360 Use :KEY-AND-VALUE instead of :EITHER, :KEY-OR-VALUE instead of :BOTH now. 1361 1362* The :LIBRARY option argument to EXT:DEF-CALL-OUT and EXT:DEF-C-VAR is now 1363 evaluated (i.e., it can now be a variable) and may take a value of 1364 :DEFAULT and :NEXT in addition to being a string as before. 1365 See <http://clisp.org/impnotes/dffi.html#def-c-var> and 1366 <http://clisp.org/impnotes/dffi.html#def-call-out> for details. 1367 1368* New user variable CUSTOM:*PRINT-SYMBOL-PACKAGE-PREFIX-SHORTEST* 1369 allows using the shortest package (nick)name as the symbol prefix. 1370 See <http://clisp.org/impnotes/sym-pack-prefix.html#pr-sym-pack-prefix> 1371 for details. 1372 1373* The user commands can now be extended using CUSTOM:*USER-COMMANDS*. 1374 See <http://clisp.org/impnotes/repl.html#user-commands> for details. 1375 1376* Initialization and finalization of the CLISP process can now be 1377 augmented with CUSTOM:*INIT-HOOKS* and CUSTOM:*FINI-HOOKS*. 1378 See <http://clisp.org/impnotes/custom-init-fini.html#init-hooks> and 1379 <http://clisp.org/impnotes/custom-init-fini.html#fini-hooks> for details. 1380 1381* SET functions (like UNION et al) are now much faster on large lists. 1382 1383* The second, optional argument of EXT:SPECIAL-VARIABLE-P can no longer be T; 1384 please use (THE-ENVIRONMENT) instead. 1385 1386* New function EXT:FEATUREP - the run-time version of read-time #+/#-. 1387 See <http://clisp.org/impnotes/featurep.html> for details. 1388 1389* Bug fixes: 1390 + The interpreter no longer executes the body of (EVAL-WHEN (COMPILE) ...) 1391 forms. 1392 + Fixes to internationalized error messages. 1393 + When an interpreted INITIALIZE-INSTANCE method uses CALL-NEXT-METHOD with 1394 a modified argument list, MAKE-INSTANCE could in some cases initialize 1395 the new object three times instead of just once. 1396 + Fixed a compiler bug that could lead to incorrect code when a LAMBDA 1397 with SPECIAL-declared optional variables was compiled inline and the 1398 initforms of the optional variables depended on the values of the previous 1399 optional variables. 1400 + Passing a package as second argument of RENAME-PACKAGE led to an 1401 unjustified error. 1402 + Passing a displaced vector as argument to REVERSE could lead to an 1403 unjustified error. 1404 + FRESH-LINE did not work in some situations. 1405 + Fixed ATANH on complex numbers. 1406 + The macros EXT:LETF and EXT:LETF* now work correctly on symbol-macros. 1407 + Fixed a spurious crash of MULTIPLE-VALUE-SETQ in interpreted code. 1408 + Fixed a crash of (COPY-READTABLE NIL some-readtable). 1409 + Fixed a crash when using a hash-table as hash-table key. 1410 + Fixed a crash triggered by the READ-BYTE function on streams with 1411 element type ([UN]SIGNED-BYTE n), 24 < n < 32, on big-endian platforms. 1412 + Fixed a crash that occurred on glibc platforms when writing Unicode 1413 characters in the range #\U000E0000..#\U000E007F on a stream with an 1414 encoding other than UTF-8. 1415 + An invalid bignum could be returned by GET-INTERNAL-RUN-TIME on 64-bit 1416 platforms. 1417 + Third party code walkers can now handle HANDLER-BIND et al. 1418 1419* Woe32 distribution now comes with a binary driver clisp.exe. 1420 Do not copy it anywhere - create a shortcut to it instead! 1421 Use install.bat to automate shortcut creation. 1422 1423* (SOFTWARE-TYPE) now returns memory model information, 1424 valuable in bug reports. 1425 1426Modules 1427------- 1428 1429* New module matlab interfaces to <http://www.mathworks.com/products/matlab/> 1430 and allows complicated matrix computations. 1431 See <http://clisp.org/impnotes/matlab.html> for details. 1432 1433* New module rawsock offers low-level socket access. 1434 Thanks to Fred and Don Cohens. 1435 See <http://clisp.org/impnotes/rawsock.html> for details. 1436 1437* New module zlib interfaces to <http://www.zlib.org> and allows 1438 compression and uncompression of vectors. 1439 See <http://clisp.org/impnotes/zlib.html> for details. 1440 1441* New module i18n now contains the GNU gettext interface as well as 1442 other functionality for Lisp program internationalization. 1443 See <http://clisp.org/impnotes/i18n-mod.html> for details. 1444 1445* New module PARI interfaces to <http://pari.math.u-bordeaux.fr/>. 1446 See <http://clisp.org/impnotes/pari.html> for details. 1447 1448* Module syscalls is significantly expanded. 1449 See <http://clisp.org/impnotes/syscalls.html> for details. 1450 1451* Module Berkeley-DB is vastly expanded. 1452 See <http://clisp.org/impnotes/berkeley-db.html> for details. 1453 Added support for Berkeley DB 4.3. 1454 1455* Modules now have an exit function. 1456 See <http://clisp.org/impnotes/modules.html#modfini> for details. 1457 1458Portability 1459----------- 1460 1461* Heaps and memory images larger than 4 GB are now supported on 64-bit 1462 platforms. 1463 1464* Support files larger than 2 GB or 4 GB also on Windows. 1465 1466* Weak pointers now also work on platforms without mmap(). 1467 1468* Weak hash tables now also work on platforms without mmap(). 1469 1470* Dynamic modules now work on woe32 too. 1471 1472* On most 64-bit platforms, fixnums are now 49 bits wide (including the sign 1473 bit), instead of 33 bits wide. 1474 1475 14762.33.2 (2004-06-02) 1477=================== 1478 1479Portability 1480----------- 1481 1482* Support for the Linux/x86 distributions called Redhat Fedora and Redhat 1483 Enterprise Linux. 1484 1485 14862.33.1 (2004-05-22) 1487=================== 1488 1489User visible changes 1490-------------------- 1491 1492* Bug fixes: 1493 + The return value of ASINH was always rounded to a SINGLE-FLOAT. 1494 + The return value of NSTRING-UPCASE, NSTRING-DOWNCASE, NSTRING-CAPITALIZE, 1495 WRITE-STRING, WRITE-LINE, when called with a displaced string as argument, 1496 was wrong. 1497 + Some cases of ,@ inside doubly-nested backquote led to an unjustified 1498 error. 1499 1500Portability 1501----------- 1502 1503* Improved portability for Solaris/SPARC64 in 64-bit mode. 1504 1505* Buildable with GCC-3.4. 1506 1507* Fixed a bug in (ASH x MOST-NEGATIVE-FIXNUM) on some platforms. 1508 1509* Fixed a bug in (SIGNUM negative-single-float) on 64-bit platforms. 1510 1511* Fixed a bug in (LOGAND fixnum bignum), (LOGNAND fixnum bignum), 1512 (LOGANDC2 fixnum bignum), (LOGANDC1 bignum fixnum) on some rare platforms. 1513 1514 15152.33 (2004-03-17) 1516================= 1517 1518Important notes 1519--------------- 1520 1521* All .fas files generated by previous CLISP versions are invalid and 1522 must be recompiled. Use CUSTOM:*LOAD-OBSOLETE-ACTION* to automate this. 1523 See <http://clisp.org/impnotes/loadfile.html> for details. 1524 1525User visible changes 1526-------------------- 1527 1528* NO-APPLICABLE-METHOD, NO-PRIMARY-METHOD and NO-NEXT-METHOD now signal 1529 METHOD-CALL-ERROR or METHOD-CALL-TYPE-ERROR. 1530 See <http://clisp.org/impnotes/std-meth-combo.html#meth-call-err> for details. 1531 1532* New user variables CUSTOM:*APROPOS-MATCHER* and CUSTOM::*APROPOS-DO-MORE* 1533 make APROPOS more flexible in search and output. 1534 See <http://clisp.org/impnotes/debugger.html#apropos> for details. 1535 1536* New function EXT:MOD-EXPT efficiently computes the composition of MOD 1537 and EXPT on integers. 1538 See <http://clisp.org/impnotes/num-concepts.html#int-func-ext> for details. 1539 1540* New function EXT:ARGV returns the command line arguments passed to runtime. 1541 See <http://clisp.org/impnotes/environment-enq.html#argv> for details. 1542 1543* New generic function GRAY:STREAM-POSITION extends FILE-POSITION to 1544 Gray streams; FILE-POSITION now works with streams other than FILE-STREAMs. 1545 See <http://clisp.org/impnotes/gray.html> for details. 1546 1547* DEFINE-METHOD-COMBINATION and friends are now implemented. 1548 Thanks to James Anderson <james.anderson@setf.de>. 1549 This change obsoleted all compiled file. 1550 1551Portability 1552----------- 1553 1554* Improved portability for nearly all platforms: Linux, MacOS X, Solaris, 1555 Tru64, HP-UX, AIX, FreeBSD, NetBSD, OpenBSD, BeOS. 1556 1557* Removed Acorn RISCOS support. 1558 1559* Removed AmigaOS support. 1560 1561* Removed support for MSDOS and OS/2, using EMX. 1562 1563* Removed support for Borland C compiler on Win32. 1564 1565* Added FFI support for x86_64 (AMD64) Linux and PowerPC MacOS X. 1566 1567 15682.32 (2003-12-29) 1569================= 1570 1571User visible changes 1572-------------------- 1573 1574* WRITE-BYTE-SEQUENCE now accepts :NO-HANG keyword argument. 1575 Thanks to Don Cohen <don-sourceforge@isis.cs3-inc.com>. 1576 1577* Support files larger than 2 GB or 4 GB on platforms with LFS 1578 (Large File Support). 1579 1580* New module Berkeley-DB interfaces to 1581 <http://www.sleepycat.com/docs/api_c/frame.html> 1582 and allows working with Berkeley DB databases. 1583 See <http://clisp.org/impnotes/berkeley-db.html> for details. 1584 1585* New module pcre interfaces to <http://www.pcre.org/> and 1586 makes Perl Compatible Regular Expressions available in CLISP. 1587 See <http://clisp.org/impnotes/pcre.html> for details. 1588 1589* Module syscalls now exports function POSIX:STAT-VFS. 1590 See <http://clisp.org/impnotes/syscalls.html> for details. 1591 1592* When the system C library provides a wildcard (fnmatch) implementation, 1593 it is used instead of the GNU wildcard distributed with CLISP 1594 when the CLISP wildcard module is built. 1595 1596* Prompt is now fully customizable by the user. 1597 CUSTOM:*PROMPT* is replaced with 5 variables. 1598 See <http://clisp.org/impnotes/prompt.html> for details. 1599 1600* Readline is now used properly on Cygwin/X11. 1601 1602* Command line interface: the initial verbosity level is controlled 1603 by the pair of mutually canceling options -q/-v. 1604 See <http://clisp.org/impnotes/clisp.html#opt-verbose> for details. 1605 1606 16072.31 (2003-09-01) 1608================= 1609 1610Important notes 1611--------------- 1612 1613* All .fas files generated by previous CLISP versions are invalid and 1614 must be recompiled. This is not as bad as it was before: the invalid 1615 files will be ignored and the sources will be loaded instead of 1616 signaling an error unless you set CUSTOM:*LOAD-OBSOLETE-ACTION*. 1617 See <http://clisp.org/impnotes/loadfile.html> for details. 1618 1619* All custom-written external modules must be updated to reflect 1620 changes in the C definitions, e.g. many C types were renamed to a 1621 trailing _t (subr_t, object_initdata_t) and LISPFUN takes an 1622 additional side-effect class (seclass) parameter. 1623 1624User visible changes 1625-------------------- 1626 1627* Added a new module - "fastcgi": an interface to the FastCGI 1628 Web server CGI-compatible protocol (see http://www.fastcgi.com/) 1629 Thanks to John K. Hinsdale <hin@alma.com>. 1630 See <http://clisp.org/impnotes/fastcgi.html> for details. 1631 1632* External modules now work on win32 (when used with cygwin or mingw). 1633 See <http://clisp.org/impnotes/modules.html#mod-win32> for details. 1634 1635* DIRKEY is now a standard module: use `--with-module=dirkey' 1636 instead of `--with-dir-key' when configuring. 1637 See <http://clisp.org/impnotes/dir-key.html> for details. 1638 1639* SYSCALLS is now a standard module: use `--with-module=syscalls 1640 instead of `--with-export-syscalls' when configuring. 1641 See <http://clisp.org/impnotes/syscalls.html> for details. 1642 1643* New module netica interfaces to <http://norsys.com/netica_c_api.htm> 1644 and allows working with Bayesian belief networks and influence diagrams. 1645 See <http://clisp.org/impnotes/netica.html> for details. 1646 1647* READ-BYTE-SEQUENCE now accepts :NO-HANG keyword argument. 1648 1649* LOAD now takes an additional keyword argument :OBSOLETE-ACTION which 1650 specifies what to do with the obsolete .fas files. 1651 See <http://clisp.org/impnotes/loadfile.html> for details. 1652 1653* EXT:SPECIAL-VARIABLE-P now accepts a second optional ENVIRONMENT argument. 1654 See <http://clisp.org/impnotes/declarations.html#spe-var-p> for details. 1655 1656* You can now set socket options using new function SOCKET:SOCKET-OPTIONS. 1657 See <http://clisp.org/impnotes/socket.html#so-opt> for details. 1658 Suggested by Dave Richards <dave@synergy.org>. 1659 1660* SOCKET:SOCKET-STATUS now distinguishes between :EOF and :INPUT. 1661 Also, it does not have to cons up a fresh list even for multiple streams. 1662 See <http://clisp.org/impnotes/socket.html#so-status> for details. 1663 1664* CLISP character set now uses Unicode 3.2. 1665 See <http://clisp.org/impnotes/characters.html> for details. 1666 1667* DIRECTORY now accepts a new keyword argument :IF-DOES-NOT-EXIST which 1668 controls treatment of links pointing to non-existent files. 1669 It defaults to :DISCARD which is fully backward compatible. 1670 See <http://clisp.org/impnotes/dir-func.html#dir> for details. 1671 1672* DELETE-FILE no longer calls TRUENAME on its argument, which enables 1673 you to delete symbolic links. This is an incompatible change. 1674 You can get the old behavior by doing (DELETE-FILE (TRUENAME path)). 1675 See <http://clisp.org/impnotes/file-func.html#del-file> for details. 1676 1677* DRIBBLE now works by redefining *TERMINAL-IO* instead of a host of 1678 i/o variables. This allows DRIBBLE to be started and stopped in 1679 different break loops. 1680 See <http://clisp.org/impnotes/debugger.html#dribble> for details. 1681 1682* Weak hash tables can now remove key/value pairs when either or both 1683 are garbage collected. 1684 See <http://clisp.org/impnotes/make-hash.html> for details. 1685 1686* You can use (SETF WEAK-POINTER-VALUE) to change the object to which 1687 the given weak pointer point to. 1688 See <http://clisp.org/impnotes/weak.html> for details. 1689 1690* New macro EXT:DEFINE-HASH-TABLE-TEST allows user-defined hash table tests. 1691 See <http://clisp.org/impnotes/defhash.html> for details. 1692 1693* ANSI CL compliance issues: 1694 + MAPC, MAPCAR, MAPCAN, MAPL, MAPLIST, MAPCON now require their list 1695 arguments to be proper lists; 1696 + TAILP uses EQL, not EQ, to compare the sublists; 1697 + LOOP was fixed in many many ways, including 1698 - using ATOM as the end test for ON iteration, 1699 - returning the SUMs (and alike) of the specified type (if any), 1700 - checking that the THEREIS return value is not shadowed, 1701 - treating keyword IT in an inappropriate place as a variable, 1702 - signaling SOURCE-PROGRAM-ERROR errors at macroexpansion time, 1703 - not requiring the package argument for symbol iteration, 1704 - making local variables accessible in the INITIALLY clauses, 1705 - initializing accumulation variables after iteration variables 1706 to avoid shadowing, 1707 - using forward consing for APPEND/NCONC because REVAPPEND/NRECONC 1708 drop the last atom in dotted lists, 1709 - checking for duplicate variables in iteration clauses; 1710 + DOCUMENTATION is now a generic function; 1711 + implemented CHANGE-CLASS, UPDATE-INSTANCE-FOR-DIFFERENT-CLASS, 1712 MAKE-INSTANCES-OBSOLETE, UPDATE-INSTANCE-FOR-REDEFINED-CLASS, and 1713 ENSURE-GENERIC-FUNCTION; 1714 + DEFCLASS no longer requires that direct superclasses already exist; 1715 + sequence functions (MAP, LENGTH and such) no longer accept dotted lists 1716 and treat NULL as LIST of length 0 and CONS as LIST of positive length; 1717 + COERCE accepts CLOS class object as a type-spec (second argument) and 1718 coerces FLOAT to COMPLEX by returning a COMPLEX number; 1719 + DEFSTRUCT uses the slot name as is for the accessor when :CONC-NAME 1720 is NIL (i.e., does not intern the name in *PACKAGE*), and does not 1721 bind slot names in the arglist of keyword constructors; 1722 + MAPCAN and MAPCON now correctly handle functions returning ATOMs; 1723 + removed macro definition from GENERIC-FUNCTION; 1724 + APPEND, COPY-ALIST, REVAPPEND, NRECONC, PAIRLIS, GET, GETF, 1725 REMPROP, GET-PROPERTIES no longer accept dotted lists; 1726 + implemented arrays with ARRAY-ELEMENT-TYPE NIL; 1727 + implemented ANSI CL Issues <CONDITION-RESTARTS:PERMIT-ASSOCIATION>, 1728 <DEBUGGER-HOOK-VS-BREAK:CLARIFY>, <DOCUMENTATION-FUNCTION-BUGS:FIX>, 1729 <EXTERNAL-FORMAT-FOR-EVERY-FILE-CONNECTION:MINIMUM>, 1730 <IMPORT-SETF-SYMBOL-PACKAGE>, <SETF-FIND-CLASS:ALLOW-NIL>, 1731 <SUBTYPEP-ENVIRONMENT:ADD-ARG>, <THE-VALUES:RETURN-NUMBER-RECEIVED>, 1732 <ADJUST-ARRAY-NOT-ADJUSTABLE:IMPLICIT-COPY>; 1733 + EQUALP on HASH-TABLEs now correctly descends the structure; 1734 + macro definitions now respect the lexical environment; 1735 + more thorough lambda list matching check; 1736 + DEFINE-CONDITION now return the condition name; 1737 + a character is now accepted as a package designator. 1738 Thanks to Paul F. Dietz <dietz@dls.net> and his ANSI compliance 1739 suite, which helped detect some of these deficiencies. 1740 1741* FUNCTION-LAMBDA-EXPRESSION now always returns the correct function name. 1742 See <http://clisp.org/impnotes/misc-data.html#fle> for details. 1743 1744* CONSTANTP now detects many more constant forms. 1745 See <http://clisp.org/impnotes/declarations.html#constantp> for details. 1746 1747* The code walker has now a public interface: EXT:EXPAND-FORM. 1748 See <http://clisp.org/impnotes/code-walk.html> for details. 1749 1750* Renamed macro SPACE to EXT:TIMES because SPACE is an ANSI Common Lisp 1751 symbol without a macro definition. 1752 See <http://clisp.org/impnotes/debugger.html#time> for details. 1753 1754* New function EXT:XOR checks that exactly one of its arguments is non-NIL. 1755 See <http://clisp.org/impnotes/xor.html> for details. 1756 1757* New function EXT:MAKE-STREAM creates a stream out of a file descriptor 1758 and facilitates CGI scripting. 1759 See <http://clisp.org/impnotes/make-stream.html> and 1760 <http://clisp.org/impnotes/stream-eltype.html#bin-stdio> for details. 1761 1762* New function EXT:MODULE-INFO provides information about the CLISP 1763 modules that comprise the running image. 1764 See <http://clisp.org/impnotes/modules.html#modinfo> for details. 1765 1766* New generic function CLOS:CLASS-PROTOTYPE from MOP. 1767 See <http://clisp.org/impnotes/mop-classes.html#class-prototype> for details. 1768 1769* New generic functions CLOS:CLASS-FINALIZED-P and 1770 CLOS:FINALIZE-INHERITANCE from MOP. 1771 See <http://clisp.org/impnotes/def-class.html> for details. 1772 1773* New FFI functionality: 1774 + functions FFI:FOREIGN-ALLOCATE and FFI:FOREIGN-FREE and macros 1775 FFI:ALLOCATE-DEEP and FFI:ALLOCATE-SHALLOW permit heap allocation; 1776 see <http://clisp.org/impnotes/dffi.html#foreign-heap> for details; 1777 + functions FFI:FOREIGN-ADDRESS-UNSIGNED and FFI:UNSIGNED-FOREIGN-ADDRESS, 1778 see <http://clisp.org/impnotes/dffi.html#faddr-u> for details; 1779 + function FFI:FOREIGN-ADDRESS, 1780 see <http://clisp.org/impnotes/dffi.html#faddr> for details; 1781 + functions FFI:FOREIGN-POINTER and (SETF FFI:FOREIGN-POINTER), 1782 see <http://clisp.org/impnotes/dffi.html#fptr> for details; 1783 + macros FFI:C-VAR-ADDRESS, FFI:C-VAR-OBJECT and FFI:OFFSET, 1784 see <http://clisp.org/impnotes/dffi.html#offset> and 1785 <http://clisp.org/impnotes/dffi.html#c-var-addr>; 1786 + function (SETF FFI:VALIDP) invalidates foreign objects 1787 see <http://clisp.org/impnotes/dffi.html#validp> for details; 1788 + macros FFI:WITH-FOREIGN-STRING, and macro FFI:WITH-C-PLACE, 1789 see <http://clisp.org/impnotes/dffi.html#foreign-stack-string> and 1790 <http://clisp.org/impnotes/dffi.html#with-c-place>. 1791 Thanks to Jörg Höhle <hoehle@users.sourceforge.net>. 1792 + FFI:DEF-CALL-OUT and FFI:DEF-C-VAR now accept a :LIBRARY option which 1793 allows you to specify the dynamic library which contains the object. 1794 See <http://clisp.org/impnotes/dffi.html#def-call-out> and 1795 <http://clisp.org/impnotes/dffi.html#def-c-var>. 1796 + Introduced a bit of polymorphism: FFI:C-POINTER can be NIL and will 1797 be treated as NULL; NULL return value of type FFI:C-POINTER is 1798 returned as NIL. 1799 See <http://clisp.org/impnotes/dffi.html#c-pointer>. 1800 + You can now map between numeric and symbolic C enum values using 1801 functions FFI:ENUM-FROM-VALUE and FFI:ENUM-TO-VALUE. 1802 See <http://clisp.org/impnotes/dffi.html#def-c-enum>. 1803 1804* FFI does not output extern variable and function declarations unless 1805 you set FFI:*OUTPUT-C-VARIABLES* and/or FFI:*OUTPUT-C-FUNCTIONS* to T. 1806 Please use FFI:C-LINES to include the appropriate headers instead. 1807 See <http://clisp.org/impnotes/dffi.html#ffi-extern-output> for details. 1808 1809* Regexp module functions now support more options, e.g., :EXTENDED to 1810 use extended regular expressions, and do not rely on FFI. 1811 In particular, REGEXP:REGEXP-COMPILE now accepts keyword and not 1812 optional arguments (this is not backwards compatible). 1813 When the system library provides a regexp implementation, 1814 it is used instead of the GNU regexp distributed with CLISP. 1815 The number of subexpressions is now unlimited (the limit was 10). 1816 See <http://clisp.org/impnotes/regexp-mod.html> for details. 1817 1818* Unified modules postgresql632 and postgresql642 into postgresql. 1819 The postgresql module works with PostgreSQL 6 and 7 now. 1820 1821* Removed obsolete module linuxlibc5 and renamed module linuxlibc6 to glibc. 1822 1823* New module: bindings/win32 (highly incomplete, patches are welcome). 1824 1825* The BACKQUOTE reader has been reimplemented from scratch by 1826 Kaz Kylheku <kaz@ashi.footprints.net>. 1827 1828* New function EXT:MAKE-XTERM-IO-STREAM creates an input-output stream 1829 that uses a separate X terminal. Unix platforms only. 1830 See <http://clisp.org/impnotes/syscalls.html#mk-xterm-io> for details. 1831 1832* Fixed a bug in PEEK-CHAR with non-NIL peek-type on ECHO-STREAMS. 1833 1834* Fixed a bug in FILE-POSITION after UNREAD-CHAR (or PEEK-CHAR). 1835 1836* Fixed a bug in bit operations on multi-dimensional arrays. 1837 1838* CLISP/MIT-CLX now compiles CLOCC CLUE/CLIO. 1839 See <http://clocc.sourceforge.net/clocc/src/gui/clue/> and 1840 <http://clisp.org/impnotes/modules.html#incmod-gui>. 1841 1842* CLISP/NEW-CLX on win32 with Cygwin X server compiles garnet. 1843 See <https://sourceforge.net/p/clisp/mailman/message/12561966/>. 1844 1845* Command line interface: allow multiple -x options. 1846 New options -repl <http://clisp.org/impnotes/clisp.html#opt-repl> 1847 and -v (--verbose) <http://clisp.org/impnotes/clisp.html#opt-verbose>. 1848 1849 18502.30 (2002-09-15) 1851================= 1852 1853User visible changes 1854-------------------- 1855 1856* CLISP does not come with GNU libiconv anymore. The most important 1857 encodings are built-in anyway, and CLISP can use the GNU libc 2.2 1858 iconv and a GNU libiconv when it is independently installed. 1859 1860* CLISP does not come with GNU gettext anymore. This is a separate 1861 package and should be installed separately, if you wish to use i18n. 1862 1863* CLISP does not come with GNU readline anymore, because, starting with 1864 version 4.3, readline supports multibyte characters out of the box. 1865 1866* CLISP does not come with GNU libsigsegv anymore. This means that in 1867 certain cases of infinite recursion, the C stack overflow will not be 1868 properly detected and will result in a segfault instead of an error. 1869 You are urged to download and install GNU libsigsegv from 1870 <ftp://ftp.gnu.org/pub/gnu/libsigsegv/> or 1871 <http://sourceforge.net/projects/libsigsegv/> 1872 before configuring CLISP. 1873 1874* Strings can now hold UCS-4 characters, instead of only UCS-2 characters. 1875 CHAR-CODE-LIMIT increased from 65536 to 1114112. 1876 1877* Added a new module - "oracle": an interface to the Oracle ODBMS. 1878 Thanks to John K. Hinsdale <hin@alma.com>. 1879 1880* New user variable CUSTOM:*PARSE-NAMESTRING-DOT-FILE* controls 1881 how the file names starting with a dot are parsed. 1882 By default, it is set to :NAME in config.lisp, 1883 so #P".clisprc" is now #S(PATHNAME :NAME ".clisprc"). 1884 To get the old result of #S(PATHNAME :TYPE "clisprc"), 1885 set this variable to :TYPE. 1886 This is an incompatible change. 1887 See <http://clisp.org/impnotes/path-components.html#name-type-split> for details. 1888 1889* New user variable CUSTOM:*TRACE-INDENT* controls TRACE output indentation. 1890 See <http://clisp.org/impnotes/debugger.html#trace> for details. 1891 1892* SOCKET:SOCKET-ACCEPT and SOCKET:SOCKET-CONNECT now accept a :TIMEOUT 1893 keyword argument. 1894 See <http://clisp.org/impnotes/socket.html#timeout-k> for details. 1895 1896* SAVEINITMEM now accepts :START-PACKAGE, :VERBOSE, and :LOCKED-PACKAGES 1897 keyword arguments. 1898 See <http://clisp.org/impnotes/image.html> for details. 1899 1900* You can now shutdown a socket for input or output separately 1901 using SOCKET:SOCKET-STREAM-SHUTDOWN. 1902 See <http://clisp.org/impnotes/socket.html#sost-shut> for details. 1903 1904* CUSTOM:*SOURCE-FILE-TYPES* and CUSTOM:*COMPILED-FILE-TYPES* 1905 now contain strings, not pathnames. 1906 See <http://clisp.org/impnotes/loadfile.html> for details. 1907 1908* EXT:GETENV now returns all of the OS environment as an alist 1909 when its argument is omitted or NIL. 1910 See <http://clisp.org/impnotes/getenv.html> for details. 1911 1912* When configured with --with-export-syscalls, 1913 several new functions are available: 1914 POSIX:STREAM-LOCK provides an interface to flock(2); 1915 POSIX:COPY-FILE provides an interface to link(2)/symlink(2)/rename(2), 1916 (in addition to the usual file copy); 1917 POSIX:DUPLICATE-HANDLE provides an interface to dup(2)/dup2(2). 1918 Thanks to Marco Baringer for COPY-FILE and DUPLICATE-HANDLE. 1919 See <http://clisp.org/impnotes/syscalls.html> for details. 1920 1921* You can now control the CLISP exit code better by passing a 1922 non-negative integer to EXT:EXIT. 1923 See <http://clisp.org/impnotes/quit.html> for details. 1924 1925* New macros FFI:WITH-C-VAR and FFI:WITH-FOREIGN-OBJECT allow 1926 allocating C data on the stack. 1927 See <http://clisp.org/impnotes/dffi.html#foreign-stack> for details. 1928 1929* Russian translations of the user interface messages have been added. 1930 Thanks to Arseny Slobodjuck <ampy@ich.dvo.ru>. 1931 1932* When built with readline, CLISP will DESCRIBE the current function 1933 when you hit TAB after a #\Space. 1934 1935* MAKE-ENCODING now checks whether the iconv charset is valid, and 1936 signals an error if it is invalid unless given the :IF-DOES-NOT-EXIST 1937 NIL argument. 1938 1939* New debugger command Quit (:q) aborts to the top-level read-eval-print 1940 loop immediately, saving you typing :a several times. 1941 1942* When CUSTOM:*PARSE-NAMESTRING-ANSI* is non-NIL, do not accept symbols 1943 as pathname designators. 1944 See <http://clisp.org/impnotes/filename-misc.html#parsename> for details. 1945 1946* COMPILE-FILE no longer clobbers an existing *.c file when the Lisp 1947 file being compiled does not contain any FFI forms. 1948 See <http://clisp.org/impnotes/compilefile.html> for details. 1949 1950* Type COMPLEX now correctly uses UPGRADED-COMPLEX-PART-TYPE. 1951 1952* Improved accuracy of some transcendental functions, e.g., now 1953 (EXPT -5.0 2.0) return #C(25.0 0.0). 1954 1955* Fixed a bug: Conversion from bytes to string did not work for the encoding 1956 (MAKE-ENCODING :CHARSET CHARSET:UNICODE-32-LITTLE-ENDIAN 1957 :INPUT-ERROR-ACTION :IGNORE). 1958 1959* Fixed a bug in compiling duplicate keyword arguments. 1960 1961* Fixed the (destructuring-bind (&key (x x)) ...) bug. 1962 1963* Wide-mode -W backward compatibility option is now gone 1964 (defunct since 1998-09-09). This permits colons in memory image file 1965 names (necessary on Cygwin). 1966 1967* CLISP on Cygwin now understands native pathnames like "c:/gnu/clisp/" 1968 by translating them internally to "/cygdrive/c/gnu/clisp/". 1969 CLISP on Win32 now understands Cygwin pathnames like "/cygdrive/c/gnu/clisp/" 1970 by translating them internally to "c:/gnu/clisp/". 1971 You can disable this by setting CUSTOM:*DEVICE-PREFIX* to NIL. 1972 See <http://clisp.org/impnotes/filenames.html#device-prefix> for details. 1973 1974* Readline is now used properly on Cygwin. 1975 1976* DIR-KEY now works on Cygwin. 1977 1978Portability 1979----------- 1980 1981* CLISP now works on SPARC/Linux with glibc 2.2 when built with SAFETY=3. 1982 1983 19842.29 (2002-07-25) 1985================= 1986 1987User visible changes [this is a bug-fix/portability release] 1988-------------------- 1989 1990* INSPECT: fixed bugs in HTML generation, Content-Length header, 1991 removing incorrect package on exit, help in nested inspect sessions. 1992 1993* COMPILE-FILE: fixed :VERBOSE NIL handling. 1994 1995* DESCRIBE: handles DIR-KEY now. 1996 1997* (LAMBDA () (DEFMETHOD ...)) now works. 1998 1999* Fixed RETURN-FROM in deep nesting. 2000 2001* Fixed crash on errors in module initialization. 2002 2003* COMPILER-MACROs can now expand to special forms. 2004 2005* EVAL-WHEN now distinguishes between COMPILE and :COMPILE-TOPLEVEL 2006 and between LOAD and :LOAD-TOLEVEL. 2007 2008Portability 2009----------- 2010 2011* CLISP now builds with GCC-3.1 out of the box. 2012 2013 20142.28 (2002-03-03) 2015================= 2016 2017Important notes 2018--------------- 2019 2020* All .fas files generated by previous CLISP versions 2021 are invalid and must be recompiled. 2022 2023User visible changes 2024-------------------- 2025 2026* ANSI CL functions MAKE-LOAD-FORM and MAKE-LOAD-FORM-SAVING-SLOTS 2027 are implemented. 2028 2029* ANSI CL pretty printer <http://clhs.lisp.se/Body/22_b.htm> is implemented. 2030 In particular, 2031 variables *PRINT-LINES*, *PRINT-MISER-WIDTH*, *PRINT-PPRINT-DISPATCH*, 2032 macro PPRINT-LOGICAL-BLOCK, 2033 local macros PPRINT-EXIT-IF-LIST-EXHAUSTED, PPRINT-POP 2034 and functions PPRINT-DISPATCH, COPY-PPRINT-DISPATCH, SET-PPRINT-DISPATCH, 2035 PPRINT-FILL, PPRINT-LINEAR, PPRINT-TABULAR, PPRINT-TAB, 2036 PPRINT-NEWLINE, PPRINT-INDENT 2037 are implemented. 2038 See <http://clisp.org/impnotes/clpp.html> for details. 2039 2040* The functions WRITE and WRITE-TO-STRING now accept :LINES, :MISER-WIDTH 2041 and :PRINT-PPRINT-DISPATCH keyword arguments. 2042 This change requires recompilation of all .fas files. 2043 2044* Weak hash-tables are now supported. 2045 See <http://clisp.org/impnotes/make-hash.html> for details. 2046 2047* Support Cygwin's "/cygdrive/drive/path" pathname syntax on Win32. 2048 2049* New macro EXT:FCASE which allows specifying comparison function in CASE. 2050 See <http://clisp.org/impnotes/fcase.html> for details. 2051 2052* New user variable CUSTOM:*LOAD-LOGICAL-PATHNAME-TRANSLATIONS-DATABASE*. 2053 See <http://clisp.org/impnotes/filename-misc.html#load-lpt> for details. 2054 2055* Packages can now be locked and unlocked using EXT:PACKAGE-LOCK 2056 See <http://clisp.org/impnotes/pack-lock.html> for details. 2057 2058* CLISP now supports internationalized Lisp programs, via GNU gettext. 2059 Macros ENGLISH, FRANCAIS and DEUTSCH have been removed. 2060 See <http://clisp.org/impnotes/i18n.html> for details. 2061 2062* The UI language can now be changed dynamically, 2063 via symbol-macro *CURRENT-LANGUAGE*. 2064 See <http://clisp.org/impnotes/i18n.html> for details. 2065 2066* Fixed a bug: LDIFF now handles dotted lists correctly. 2067 2068 20692.27 (2001-07-17) 2070================= 2071 2072User visible changes 2073-------------------- 2074 2075* EXT:GETENV is now setfable. 2076 2077* Hostname resolution is now optional in 2078 EXT:SOCKET-STREAM-PEER and EXT:SOCKET-STREAM-LOCAL. 2079 2080* EXT:SOCKET-STATUS now accepts SOCKET-SERVERs too 2081 and the direction of the checks can be specified. 2082 2083* Added install.bat for win32 installation. 2084 2085* ANSI CL compliance: more conformant pathname handling. 2086 2087* Speed up MEMBER &co when :TEST is EQ, EQL or EQUAL. 2088 2089* Optimize away local functions that are not used 2090 (much less consing in CLOS). 2091 2092* When built with readline, CLISP allows multi-line form editing. 2093 Use M-p and M-n to move between virtual lines. 2094 2095* Fixed handling of circular structs and pointers to functions in the FFI. 2096 2097* Fixed binary I/O for streams with element type longer than one byte, 2098 but not a whole number of bytes. 2099 2100 21012.26 (2001-05-23) 2102================= 2103 2104Important notes 2105--------------- 2106 2107* The CLISP extensions have been moved from the CLtL1 package LISP to 2108 separate packages. 2109 If you rely on any of the CLISP extensions, you will need to make 2110 your packages use package EXT, which re-exports all exported symbols 2111 from all extension packages. 2112 2113* All .fas files generated by previous CLISP versions 2114 are invalid and must be recompiled. 2115 2116User visible changes 2117-------------------- 2118 2119* "LISP" is now a nickname of the ANSI CL package COMMON-LISP. 2120 "USER" is now a nickname of the ANSI CL package COMMON-LISP-USER. 2121 Support for CLtL1 has thus been removed. 2122 For the benefit of package developers, *FEATURES* now contains :LISP=CL. 2123 2124* The *FEATURES* list now contains :ANSI-CL instead of :CLTL2 even when 2125 running without '-ansi' ANSI compatibility mode. 2126 2127* ANSI CL compliance: function UPGRADED-COMPLEX-PART-TYPE implemented. 2128 2129* ANSI CL compliance: macro HANDLER-BIND invokes all handlers 2130 for the condition, not just the first one. 2131 2132* ANSI CL compliance: CHAR does not check for FILL-POINTER, while ELT does. 2133 2134* ANSI CL compliance: FUNCTION-KEYWORDS returns 2 values. 2135 2136* ANSI CL compliance: COMPILED-FUNCTION is a subtype of FUNCTION. 2137 2138* ANSI CL compliance: implemented compiler macros. 2139 2140* Conforming to the ANSI CL issue CONSTANTP-ENVIRONMENT:ADD-ARG, 2141 CONSTANTP now takes an optional second argument. 2142 2143* RUN-SHELL-COMMAND and RUN-PROGRAM now accept a :WAIT argument. 2144 2145* The compiler now checks the signature of function calls 2146 for all functions, not just the inlined built-ins. 2147 2148 21492.25.1 (2001-04-06) 2150=================== 2151 2152User visible changes [this is a bug-fix only release] 2153-------------------- 2154 2155* ANSI CL compliance: INITIALIZE-INSTANCE accepts &KEY &ALLOW-OTHER-KEYS 2156 arguments. 2157 2158* Fixed a bug: a single value was sometimes returned by READ-LINE. 2159 2160* Fixed a bug: re-exporting inherited symbols resulted in them being 2161 reported as both external and inherited by WITH-PACKAGE-ITERATOR. 2162 2163* Fixed a bug: the full image and other images created with clisp-link 2164 exited on error instead of entering the debugger. 2165 2166* Fixed a bug: COMPILE-FILE-PATHNAME could return bad results when given a 2167 non-existent INPUT-FILE argument and an OUTPUT-FILE argument with 2168 non-NIL directory part. 2169 2170* Fixed --without-unicode build. 2171 2172 21732.25 (2001-03-15) 2174================= 2175 2176Important notes 2177--------------- 2178 2179* The default extension of Lisp source files for CLISP is now ".lisp" instead 2180 of ".lsp". When both "foo.lisp" and "foo.lsp" exist, (LOAD "foo") will load 2181 "foo.lisp". 2182 2183* Changed bytecode format. All .fas files generated by previous CLISP versions 2184 are invalid and must be recompiled. 2185 2186User visible changes 2187-------------------- 2188 2189* A new version numbering scheme is adopted. 2190 2191* If an error is signalled by a form supplied with the command-line 2192 option "-x", CLISP now exits with a non-zero status. 2193 2194* The pretty-printer does not print hanging parenthesis by default now. 2195 *PRINT-RPARS* now defaults to NIL and *PRINT-INDENT-LISTS* to 1, so 2196 that the lists are printed like in CLHS and CLtL. 2197 2198* New extension: directory access (win32 registry). 2199 See <http://clisp.org/impnotes/dir-key.html> for details. 2200 2201* Support UNC pathnames (\\host\dir\name.ext) on win32. 2202 2203* Support the SCREEN package on Win32. Thanks to Arseny Slobodjuck. 2204 2205* New functions CONVERT-STRING-FROM-BYTES and CONVERT-STRING-TO-BYTES. 2206 2207* Support for non-blocking binary I/O. 2208 New functions READ-BYTE-LOOKAHEAD, READ-BYTE-WILL-HANG-P, READ-BYTE-NO-HANG. 2209 New generic functions STREAM-READ-BYTE-LOOKAHEAD, 2210 STREAM-READ-BYTE-WILL-HANG-P, STREAM-READ-BYTE-NO-HANG. 2211 2212* CONCATENATED-STREAM-STREAMS now returns only the remaining streams, 2213 as per ANSI CL spec. 2214 2215* Implemented ANSI CL function INSPECT, 2216 and a function LISP:CLHS for access of Common Lisp HyperSpec. 2217 2218* Characters have now the same names as in Unicode 3.0, with space replaced 2219 by underscore. 2220 2221* ANSI CL compliance: CALL-NEXT-METHOD and NEXT-METHOD-P are now implemented 2222 as local functions, not local macros. It is now possible to call 2223 (APPLY #'CALL-NEXT-METHOD argument-list-of-unknown-length). 2224 2225* ANSI CL compliance: LOAD has a new keyword argument :EXTERNAL-FORMAT. 2226 2227* ANSI CL compliance: When an end-of-stream occurs, READ, READ-CHAR, PEEK-CHAR, 2228 READ-CHAR-NO-HANG, READ-LINE, READ-BYTE, READ-INTEGER, READ-FLOAT, called 2229 with arguments eof-error-p = NIL and without eof-value, now return NIL 2230 instead of #<END OF FILE>. 2231 2232* ANSI CL compliance: When LISP:*PARSE-NAMESTRING-ANSI* is non-NIL, 2233 PARSE-NAMESTRING parses strings with colons as logical pathnames. 2234 2235* New supported character sets in package CHARSET: GB18030, BIG5HKSCS. 2236 2237* Arguments passed to MAKE-PATHNAME with value NIL are not overridden by 2238 pathname slots in the :DEFAULTS argument any more. 2239 2240* STREAM-ELEMENT-TYPE of a TWO-WAY-STREAM or an ECHO-STREAM now depends on 2241 the stream's constituents. Previously, it was always (OR CHARACTER INTEGER). 2242 2243* Fixed a bug: REPLACE signalled an error if the source and destination 2244 sequences were the same and the source and destination ranges did not 2245 overlap. 2246 2247* Fixed a bug: A garbage collection during the execution of a foreign function 2248 callback caused a crash. 2249 2250* Fixed a bug: Calling READ-LINE on a stream already positioned at EOF caused 2251 a crash on 64-bit platforms. 2252 2253* Fixed a bug: For long-floats, (EQL x (- x)) returned true. 2254 2255* Fixed a bug: OPEN now returns NIL when the filename's directory does not 2256 exist and :IF-DOES-NOT-EXIST NIL was specified. Previously, an error was 2257 signalled except when :DIRECTION was :PROBE. 2258 2259* Fixed a bug: (subtypep 'fundamental-stream 'stream) returned NIL. 2260 2261Portability 2262----------- 2263 2264* Added support for IA-64 running Linux. 2265 2266* Added support for BeOS 5. Thanks to Alexis Rivera Rios <ahrivera@yahoo.com>. 2267 2268* Removed support for DOS. Not to worry, OS/2 and Win32 are still supported. 2269 2270 22712.24 (2000-03-06) 2272================= 2273 2274User visible changes 2275-------------------- 2276 2277* New functions READ-FLOAT and WRITE-FLOAT. 2278 2279* Implemented ANSI CL macro WITH-COMPILATION-UNIT. 2280 2281* Unicode support: The pretty-printer and FORMAT ~T now handle non-spacing and 2282 double-width Unicode characters correctly. Pretty-printer slows down by 30%. 2283 New functions CHAR-WIDTH, STRING-WIDTH. 2284 2285* Fixed two bugs in TRANSLATE-PATHNAME: Substitution of "**" did not work. 2286 Substitutions without version into non-logical pathnames crashed. 2287 2288* Dutch translations of the user interface messages have been added 2289 Thanks to Tijs van Bakel <smoke@casema.net>. 2290 2291* When configured with --with-export-syscalls, :SYSCALLS is in *FEATURES* 2292 and functions POSIX:RESOLVE-IP-ADDR, POSIX:USER-DATA, POSIX:FILE-STAT, 2293 POSIX:SYSINFO, POSIX:RESOURCE-USAGE-LIMITS, 2294 as well as those libm.so functions which do not have a better 2295 counterpart in ANSI CL are available. 2296 2297* New supported character sets in package CHARSET: ISO-8859-16, KOI8-U, 2298 KOI8-RU, EUC-JP, SHIFT-JIS, CP932, ISO-2022-JP, ISO-2022-JP-2, ISO-2022-JP-1, 2299 EUC-CN, HZ, GBK, CP936, EUC-TW, BIG5, CP950, ISO-2022-CN, ISO-2022-CN-EXT, 2300 EUC-KR, CP949, ISO-2022-KR, ARMSCII-8, GEORGIAN-ACADEMY, GEORGIAN-PS, 2301 TIS-620, MULELAO-1, CP1133, VISCII, TCVN, UTF-16, UTF-7, MACINTOSH (as an 2302 alias for MAC-ROMAN). 2303 2304Other modifications 2305------------------- 2306 2307* Speed up some sequence functions when operating on vectors: MAKE-SEQUENCE, 2308 CONCATENATE, COPY-SEQ, COERCE, SUBSEQ, REPLACE, FILL, REVERSE, NREVERSE, 2309 REMOVE[-IF[-NOT]] with :START/:END, SUBSTITUTE[-IF[-NOT]] with :START/:END, 2310 SORT. 2311 2312* Speed up ADJUST-ARRAY. 2313 2314 23152.23 (1999-07-22) 2316================= 2317 2318User visible changes 2319-------------------- 2320 2321* Added a new module - "postgresql": interface to the PostgreSQL ODBMS. 2322 2323* Implemented ANSI CL macro WITH-PACKAGE-ITERATOR. 2324 2325* Conforming to ANSI CL issue <ALLOCATE-INSTANCE:ADD>: New function 2326 ALLOCATE-INSTANCE. 2327 2328* Conforming to ANSI CL issue <GENERIC-FLET-POORLY-DESIGNED:DELETE>: The 2329 symbols GENERIC-FLET and GENERIC-LABELS are not exported from the 2330 COMMON-LISP package any more. 2331 2332* Conforming to ANSI CL issues <KEYWORD-ARGUMENT-NAME-PACKAGE:ANY> and 2333 <MULTIPLE-VALUE-SETQ-ORDER:LIKE-SETF-OF-VALUES>. 2334 2335* Conforming to ANSI CL Issue <MACRO-FUNCTION-ENVIRONMENT:YES> 2336 MACRO-FUNCTION now takes an optional second argument ENV. 2337 2338* When CLISP is invoked with an "-a" option, *features* contain :ANSI-CL. 2339 2340* Weak pointers are implemented. New functions MAKE-WEAK-POINTER, 2341 WEAK-POINTER-P, WEAK-POINTER-VALUE. 2342 2343* The function OPEN, when creating unbuffered file streams, now supports any 2344 of the following :ELEMENT-TYPEs: CHARACTER and ([UN]SIGNED-BYTE n), where n 2345 is a multiple of 8. 2346 2347* The functions 2348 MAKE-PIPE-INPUT-STREAM, MAKE-PIPE-OUTPUT-STREAM, MAKE-PIPE-IO-STREAM, 2349 SOCKET-ACCEPT, SOCKET-CONNECT 2350 accept a keyword argument :ELEMENT-TYPE. Possible values are types 2351 equivalent to CHARACTER or (UNSIGNED-BYTE n), (SIGNED-BYTE n), where n is 2352 a positive multiple of 8. Previously these functions returned streams whose 2353 element-type was (OR CHARACTER (UNSIGNED-BYTE 8)). 2354 2355* STREAM-ELEMENT-TYPE is SETFable. The element type of streams created by the 2356 functions MAKE-PIPE-INPUT-STREAM, MAKE-PIPE-OUTPUT-STREAM, 2357 MAKE-PIPE-IO-STREAM, SOCKET-ACCEPT, SOCKET-CONNECT can be modified, if the 2358 old and the new element type are compatible. 2359 (UNSIGNED-BYTE n) and (SIGNED-BYTE n) are compatible, and CHARACTER is 2360 compatible with ([UN]SIGNED-BYTE 8). 2361 2362* Character I/O can now be customized via encodings. A stream's external 2363 format is an encoding, and the symbol macros 2364 *DEFAULT-FILE-ENCODING*, *PATHNAME-ENCODING*, *TERMINAL-ENCODING*, 2365 *MISC-ENCODING*, FFI:*FOREIGN-ENCODING*, AFFI:*FOREIGN-ENCODING* 2366 contain user-settable encodings. 2367 Encodings can be obtained through the function MAKE-ENCODING, and as values 2368 of the constants 2369 CHARSET:UCS-2, CHARSET:UNICODE-16, CHARSET:UNICODE-16-BIG-ENDIAN, 2370 CHARSET:UNICODE-16-LITTLE-ENDIAN, CHARSET:UCS-4, CHARSET:UNICODE-32, 2371 CHARSET:UNICODE-32-BIG-ENDIAN, CHARSET:UNICODE-32-LITTLE-ENDIAN, 2372 CHARSET:UTF-8, CHARSET:JAVA, CHARSET:ASCII, CHARSET:ISO-8859-1, 2373 CHARSET:ISO-8859-2, CHARSET:ISO-8859-3, CHARSET:ISO-8859-4, 2374 CHARSET:ISO-8859-5, CHARSET:ISO-8859-6, CHARSET:ISO-8859-7, 2375 CHARSET:ISO-8859-8, CHARSET:ISO-8859-9, CHARSET:ISO-8859-10, 2376 CHARSET:ISO-8859-13, CHARSET:ISO-8859-14, CHARSET:ISO-8859-15, 2377 CHARSET:KOI8-R, CHARSET:MAC-ARABIC, CHARSET:MAC-CENTRAL-EUROPE, 2378 CHARSET:MAC-CROATIAN, CHARSET:MAC-CYRILLIC, CHARSET:MAC-DINGBAT, 2379 CHARSET:MAC-GREEK, CHARSET:MAC-HEBREW, CHARSET:MAC-ICELAND, 2380 CHARSET:MAC-ROMAN, CHARSET:MAC-ROMANIA, CHARSET:MAC-SYMBOL, 2381 CHARSET:MAC-THAI, CHARSET:MAC-TURKISH, CHARSET:MAC-UKRAINE, 2382 CHARSET:CP437, CHARSET:CP737, CHARSET:CP775, CHARSET:CP850, CHARSET:CP852, 2383 CHARSET:CP855, CHARSET:CP857, CHARSET:CP860, CHARSET:CP861, CHARSET:CP862, 2384 CHARSET:CP863, CHARSET:CP864, CHARSET:CP865, CHARSET:CP866, CHARSET:CP869, 2385 CHARSET:CP874, CHARSET:WINDOWS-1250, CHARSET:WINDOWS-1251, 2386 CHARSET:WINDOWS-1252, CHARSET:WINDOWS-1253, CHARSET:WINDOWS-1254, 2387 CHARSET:WINDOWS-1255, CHARSET:WINDOWS-1256, CHARSET:WINDOWS-1257, 2388 CHARSET:WINDOWS-1258, CHARSET:HP-ROMAN8, CHARSET:NEXTSTEP. 2389 2390* The functions 2391 OPEN, MAKE-PIPE-INPUT-STREAM, MAKE-PIPE-OUTPUT-STREAM, MAKE-PIPE-IO-STREAM, 2392 SOCKET-ACCEPT, SOCKET-CONNECT 2393 and the macro 2394 WITH-OUTPUT-TO-PRINTER 2395 accept a keyword argument :EXTERNAL-FORMAT. Possible values are encodings, 2396 such as returned by the function MAKE-ENCODING, the line terminator keywords 2397 :UNIX, :MAC, :DOS, and :DEFAULT. New function STREAM-EXTERNAL-FORMAT. 2398 2399* STREAM-EXTERNAL-FORMAT is SETFable. The external format of streams created 2400 by the functions OPEN, MAKE-PIPE-INPUT-STREAM, MAKE-PIPE-OUTPUT-STREAM, 2401 MAKE-PIPE-IO-STREAM, SOCKET-ACCEPT, SOCKET-CONNECT can be modified. 2402 2403* OPEN has a new keyword argument :BUFFERED. It determines whether the file 2404 stream returned is buffered or not. Possible values for it are NIL, T, or 2405 :DEFAULT. If it is :DEFAULT, buffered file streams will be returned for 2406 regular files and (on Unix) block-devices, and unbuffered file streams for 2407 special files. 2408 2409* The functions MAKE-PIPE-INPUT-STREAM, MAKE-PIPE-OUTPUT-STREAM, 2410 MAKE-PIPE-IO-STREAM, SOCKET-ACCEPT, SOCKET-CONNECT have a new keyword 2411 argument :BUFFERED. It determines whether the stream returned is buffered or 2412 not. Possible values for it are NIL, T, or :DEFAULT. :DEFAULT is equivalent 2413 to NIL. 2414 2415* New functions READ-INTEGER, WRITE-INTEGER which can be used to do binary I/O 2416 on streams with element-type (UNSIGNED-BYTE 8). 2417 2418* The Gray proposal <STREAM-DEFINITION-BY-USER> is implemented: 2419 New classes 2420 FUNDAMENTAL-STREAM, 2421 FUNDAMENTAL-INPUT-STREAM, FUNDAMENTAL-OUTPUT-STREAM, 2422 FUNDAMENTAL-CHARACTER-STREAM, FUNDAMENTAL-BINARY-STREAM, 2423 FUNDAMENTAL-CHARACTER-INPUT-STREAM, FUNDAMENTAL-CHARACTER-OUTPUT-STREAM, 2424 FUNDAMENTAL-BINARY-INPUT-STREAM, FUNDAMENTAL-BINARY-OUTPUT-STREAM. 2425 New generic functions 2426 STREAM-READ-CHAR, STREAM-UNREAD-CHAR, STREAM-READ-CHAR-NO-HANG, 2427 STREAM-PEEK-CHAR, STREAM-LISTEN, STREAM-READ-CHAR-WILL-HANG-P, 2428 STREAM-READ-CHAR-SEQUENCE, STREAM-READ-LINE, STREAM-CLEAR-INPUT, 2429 STREAM-WRITE-CHAR, STREAM-LINE-COLUMN, STREAM-START-LINE-P, 2430 STREAM-WRITE-CHAR-SEQUENCE, STREAM-WRITE-STRING, STREAM-TERPRI, 2431 STREAM-FRESH-LINE, STREAM-FINISH-OUTPUT, STREAM-FORCE-OUTPUT, 2432 STREAM-CLEAR-OUTPUT, STREAM-ADVANCE-TO-COLUMN, 2433 STREAM-READ-BYTE, STREAM-READ-BYTE-SEQUENCE, 2434 STREAM-WRITE-BYTE, STREAM-WRITE-BYTE-SEQUENCE. 2435 The functions CLOSE, OPEN-STREAM-P, STREAM-ELEMENT-TYPE are now generic 2436 functions. 2437 See <http://clisp.org/impnotes/gray.html> for details. 2438 2439* The macros FFI:DEF-C-CALL-OUT and FFI:DEF-C-CALL-IN now add an argument 2440 :LANGUAGE :STDC (means ANSI C) instead of :LANGUAGE :C (means old K&R C). 2441 2442* Conforming with ANSI CL, SIMPLE-CONDITION now has the initarg 2443 :FORMAT-CONTROL instead of :FORMAT-STRING. New function 2444 SIMPLE-CONDITION-FORMAT-CONTROL. 2445 2446* Conforming with ANSI CL, FILE-LENGTH and FILE-POSITION, when called on 2447 an unbuffered file stream, now return NIL instead of signaling an error. 2448 2449* Conforming with ANSI CL, MACROEXPAND and MACROEXPAND-1 now accept NIL as 2450 second argument, denoting the global environment. 2451 2452* Conforming with ANSI CL, the reader now signals an error of type 2453 READER-ERROR when trying to parse tokens like 35/000 or 1.5e1000, 2454 instead of DIVISION-BY-ZERO and FLOATING-POINT-OVERFLOW, respectively. 2455 2456* On Unix, calling OPEN on a block device now returns a buffered stream 2457 instead of an unbuffered stream. 2458 2459* On Unix, writing to a pipe created by MAKE-PIPE-OUTPUT-STREAM or 2460 MAKE-PIPE-IO-STREAM after the corresponding child process has exited 2461 now leads to an error message instead of terminating the CLISP process. 2462 2463* The generic function GENERIC-STREAM-LISTEN is replaced with 2464 GENERIC-STREAM-READ-CHAR-WILL-HANG-P. 2465 2466* The function XGCD now really always returns coefficients of smallest 2467 possible absolute value. 2468 2469* Fixed a interpreter bug: (let (x) (declare (special x)) ...) did not change 2470 the global value of x in interpreted mode. 2471 2472* Fixed a bug: On Win32, Ctrl-Z sometimes caused two levels of the read-eval- 2473 print loop to be aborted instead of just one. 2474 2475* Fixed a bug: READ-CHAR-SEQUENCE, when called on a string input stream, 2476 forgot to advance the pointer into the string. 2477 2478* Fixed a bug: WRITE-CHAR-SEQUENCE on Win32 failed to convert NL to CR/LF. 2479 2480* Fixed a bug: Calling (GET-DISPATCH-MACRO-CHARACTER disp-char sub-char) would 2481 crash, instead of returning NIL, if there is no macro-character function 2482 associated with sub-char after disp-char. 2483 2484* Fixed a bug: (CHECK-TYPE place typespec string) did not evaluate `string'. 2485 2486* Fixed a bug: Calling the function FINALIZE caused a crash during the next GC 2487 on many platforms. 2488 2489* Fixed a bug: Calling a generic function without any installed method 2490 resulted in an inappropriate error message, not a call to 2491 NO-APPLICABLE-METHOD. 2492 2493* Fixed a bug: Closing a SOCKET-SERVER twice, or using a closed SOCKET-SERVER 2494 could result in inappropriate error messages. 2495 2496* Fixed a bug: (format nil "~@D" 0) ==> "+0" now. 2497 2498Portability 2499----------- 2500 2501* Added support for SPARC running Linux. 2502 2503* Added support for Apple PowerPC running MacOS X Server (a.k.a. Rhapsody). 2504 2505* Improved support for m68k running Linux. 2506 2507* Added build instructions for Win32 using MSVC 6.0. 2508 2509Other modifications 2510------------------- 2511 2512* On Linux 2.2.x with glibc-2.1, Solaris, OSF/1 and Irix, stack overflow is 2513 now caught reliably. Previously, endless recursion in interpreted code could 2514 cause a crash in some cases. 2515 2516* Speed up the function DIRECTORY on Unix in some cases. 2517 2518* Speed up compiled calls to LDB, LDB-TEST, MASK-FIELD, DPB, DEPOSIT-FIELD. 2519 2520 25212.22 (1999-01-08) 2522================= 2523 2524Important note 2525-------------- 2526 2527* Changed bytecode format. All .fas files generated by previous CLISP versions 2528 are invalid and must be recompiled. 2529 2530User visible changes 2531-------------------- 2532 2533* Conforming to ANSI CL issue <SETF-MULTIPLE-STORE-VARIABLES:ALLOW>: 2534 multiple values in ASSERT, ROTATEF, SHIFTF &c. 2535 2536* Conforming to ANSI CL issue <SETF-OF-VALUES:ADD>: `values' can take 2537 multiple value places in setf &c. 2538 2539* The variable `*prompt-with-package*' is replaced with `*prompt*', 2540 which can be a function. 2541 See <http://clisp.org/impnotes/prompt.html> for details. 2542 2543* Conforming with X3J13 writeup <FUNCTION-TYPE:X3J13-MARCH-88>, an error 2544 is now signalled when a lambda expression (not a function) is passed to 2545 APPLY, FUNCALL, SETF SYMBOL-FUNCTION, EVERY, SOME, NOTEVERY, NOTANY, 2546 SET-MACRO-CHARACTER, SET-DISPATCH-MACRO-CHARACTER. The latter two now 2547 accept a symbol instead of a function. 2548 2549* X3J13 vote <103> = writeup <IN-PACKAGE-FUNCTIONALITY:MAR89-X3J13> is 2550 implemented: COMMON-LISP:IN-PACKAGE is now a macro. LISP:IN-PACKAGE retains 2551 the old semantics as a function. 2552 The syntaxes (IN-PACKAGE "FOO") and (IN-PACKAGE :FOO) work with both 2553 variations. 2554 2555* X3J13 vote <11> = writeups <CHARACTER-PROPOSAL:2>, 2556 <CHARACTER-LOOSE-ENDS:FIX>, <CHARACTER-VS-CHAR:LESS-INCONSISTENT-SHORT>, 2557 <JUN90-TRIVIAL-ISSUES:24>, <STANDARD-REPERTOIRE-GRATUITOUS:RENAME> are 2558 implemented: Characters do not have font and bits attributes any more. 2559 The following symbols are not exported from package COMMON-LISP any more: 2560 STRING-CHAR STRING-CHAR-P 2561 CHAR-FONT-LIMIT CHAR-BITS-LIMIT 2562 CHAR-CONTROL-BIT CHAR-META-BIT CHAR-SUPER-BIT CHAR-HYPER-BIT 2563 CHAR-BITS CHAR-FONT MAKE-CHAR INT-CHAR CHAR-BIT SET-CHAR-BIT 2564 MAKE-STRING and MAKE-STRING-OUTPUT-STREAM have a new keyword argument 2565 :ELEMENT-TYPE. 2566 New types BASE-CHAR, EXTENDED-CHAR, BASE-STRING, SIMPLE-BASE-STRING. 2567 2568* X3J13 writeup <SETF-METHOD-VS-SETF-METHOD:RENAME-OLD-TERMS> is implemented: 2569 New function GET-SETF-EXPANSION, new macro DEFINE-SETF-EXPANDER. The old 2570 symbols GET-SETF-METHOD-MULTIPLE-VALUE, GET-SETF-METHOD, DEFINE-SETF-METHOD 2571 are removed from package COMMON-LISP. 2572 2573* X3J13 writeups <READER-ERROR:NEW-TYPE> and <PARSE-ERROR-STREAM:SPLIT-TYPES> 2574 are implemented: New condition classes PARSE-ERROR and READER-ERROR. 2575 2576* X3J13 writeup <UNDEFINED-VARIABLES-AND-FUNCTIONS:COMPROMISE> is implemented: 2577 New condition class UNBOUND-SLOT. New function UNBOUND-SLOT-INSTANCE. 2578 2579* X3J13 writeups <COMMON-TYPE:REMOVE> and <COMPILER-LET-CONFUSION:ELIMINATE> 2580 are implemented: COMMONP and COMPILER-LET are not exported from package 2581 COMMON-LISP any more. 2582 2583* X3J13 vote <138> = writeup <PEEK-CHAR-READ-CHAR-ECHO:FIRST-READ-CHAR> is 2584 implemented: PEEK-CHAR does less side effects than READ-CHAR followed by 2585 UNREAD-CHAR would do. 2586 2587* X3J13 writeup <SHARPSIGN-PLUS-MINUS-PACKAGE:KEYWORD> is implemented: 2588 When looking up a feature symbol in *FEATURES*, the package is no longer 2589 ignored. All initial elements of *FEATURES* are now keywords. The reader 2590 binds *PACKAGE* to #<PACKAGE KEYWORD> during #+ and #-. 2591 2592* X3J13 writeup <SLOT-MISSING-VALUES:SPECIFY> is implemented: Some of the 2593 values of SLOT-MISSING are ignored, depending on context. 2594 2595* X3J13 writeup <WITH-OPEN-FILE-SETQ:EXPLICITLY-VAGUE> is implemented: 2596 Assigning the variable bound by the WITH-INPUT-FROM-STRING, WITH-OPEN-FILE, 2597 WITH-OPEN-STREAM, WITH-OUTPUT-TO-STRING macros generates a compiler warning. 2598 2599* X3J13 writeup <SEQUENCE-TYPE-LENGTH:MUST-MATCH> is implemented: The 2600 functions MAKE-SEQUENCE, COERCE, CONCATENATE, MAP, MERGE signal an error 2601 if the result type specifies a length inconsistent with the other arguments. 2602 2603* X3J13 writeup <SYMBOL-MACROS-AND-PROCLAIMED-SPECIALS:SIGNALS-AN-ERROR> is 2604 implemented: SYMBOL-MACROLET of special variables or constants now signals 2605 an error. 2606 2607* Conforming with X3J13 writeup <DOTTED-LIST-ARGUMENTS:CLARIFY>, the first 2608 argument of LDIFF may now be a dotted list. 2609 2610* PATHNAME-MATCH-P and TRANSLATE-PATHNAME now treat missing pathname 2611 components the same as wild ones. 2612 2613* Renamed function SOCKET-STREAM-PEER-HOST to SOCKET-STREAM-PEER. New 2614 functions SOCKET-STREAM-LOCAL and SOCKET-SERVER-HOST. 2615 2616* Conforming to ANSI CL, DEFSTRUCT with option :INCLUDE now does not define 2617 accessors which were already defined in a superclass DEFSTRUCT. This solves 2618 the problems that occur when using the same :CONC-NAME for the new and the 2619 inherited structure, without need for the DEFSTRUCT option :INHERIT. 2620 2621* The functions MAKE-BROADCAST-STREAM, MAKE-CONCATENATED-STREAM, 2622 MAKE-TWO-WAY-STREAM, MAKE-ECHO-STREAM now verify that their arguments are 2623 input streams or output streams, respectively. 2624 2625* The function EQUALP now ignores the element type of arrays and looks only 2626 at the array contents, as specified by ANSI CL. 2627 2628* The *FEATURES* list now contains the symbol CLTL2 instead of the symbol 2629 CLTL1. 2630 2631* The limit for file size of files that can be accessed by CLISP is increased: 2632 4 GB for character streams, 512 MB for integer streams. The previous limits 2633 were 16 MB for character streams, 2 MB for integer streams. 2634 2635* Fixed a bug: Calling the function INTERACTIVE-STREAM-P with a non-stream 2636 argument could cause a crash. 2637 2638* Fixed a bug in the LOOP macro: OF-TYPE was not supported in numeric 2639 accumulation clauses (COUNT/SUM/MAXIMIZE/MINIMIZE). 2640 2641* Fixed a bug in the LOOP macro: The FOR clauses FROM/TO/BY can now be given 2642 in any order. 2643 2644* Fixed a bug: (UPGRADED-ARRAY-ELEMENT-TYPE 'STANDARD-CHAR) returned T instead 2645 of STRING-CHAR. 2646 2647* Fixed a bug: The function CERROR signalled an error if more than two 2648 arguments were given and the second argument was a condition. 2649 2650* Fixed a bug: Hash tables with test #'EQUALP did not work correctly when the 2651 keys are characters, multi-dimensional arrays or pathnames. 2652 2653* The function VALUES-LIST now verifies that its argument is a proper list. 2654 2655* The function XGCD now in most cases (but not always) returns coefficients of 2656 smallest possible absolute value. Suggested by the LiDIA group. 2657 2658Portability 2659----------- 2660 2661Other modifications 2662------------------- 2663 2664 26652.21 (9 September 1998) 2666======================= 2667 2668Important note 2669-------------- 2670 2671* Changed bytecode format. All .fas files generated by previous CLISP versions 2672 are invalid and must be recompiled. 2673 2674User visible changes 2675-------------------- 2676 2677* The 16 MB memory size limit on 32-bit machines is gone. No need for 2678 wide-mode binaries any more. The "makemake" option --with-wide is not 2679 supported any more. The command-line option -W is supported for backward 2680 compatibility, but will be removed in the future. 2681 2682* New variables *WARN-ON-FLOATING-POINT-CONTAGION* and 2683 *FLOATING-POINT-CONTAGION-ANSI*. 2684 2685* New function PROBE-DIRECTORY which tests for the existence of a directory. 2686 Suggested by many people. 2687 2688* New FORMAT directives ~/ (ANSI standard) and ~! (a better alternative). 2689 2690* ANSI CL variable *PRINT-RIGHT-MARGIN* is implemented. 2691 2692* The functions WRITE and WRITE-TO-STRING take the :RIGHT-MARGIN key argument. 2693 2694* X3J13 writeup <TYPE-BOOLEAN> is implemented: New type BOOLEAN. 2695 Suggested by Sam Steingold. 2696 2697* X3J13 writeup <ARGUMENT-MISMATCH-ERROR-MOON:FIX> is implemented: 2698 Errors during function calls (too few arguments, too many arguments, 2699 invalid keyword arguments, odd number of keyword arguments, unrecognized 2700 keyword arguments) are now of type PROGRAM-ERROR. 2701 2702* X3J13 writeup <ENSURE-DIRECTORIES-EXIST> is implemented: 2703 New function ENSURE-DIRECTORIES-EXIST. 2704 Suggested by Pierpaolo Bernardi. 2705 2706* X3J13 writeup <ISO-COMPATIBILITY:ADD-SUBSTRATE> is implemented: 2707 The macro DEFINE-SYMBOL-MACRO is now exported from package COMMON-LISP. 2708 Suggested by Pierpaolo Bernardi. 2709 2710* X3J13 writeup <DISPLACED-ARRAY-PREDICATE> is implemented: 2711 New function ARRAY-DISPLACEMENT. 2712 2713* X3J13 writeup <CLASS-OBJECT-SPECIALIZER:AFFIRM> is implemented: 2714 Class objects can now be used as parameter specializer names (not only 2715 symbols and lists of the form (EQL object)). 2716 2717* X3J13 writeup <COMPILE-FILE-OUTPUT-FILE-DEFAULTS:INPUT-FILE> is implemented: 2718 When :OUTPUT-FILE is given to COMPILE-FILE or COMPILE-FILE-PATHNAME, missing 2719 pathname components are merged in from the input file pathname. 2720 2721* X3J13 writeup <COMPILE-FILE-PATHNAME-ARGUMENTS:MAKE-CONSISTENT> is 2722 implemented: COMPILE-FILE-PATHNAME accepts any keyword arguments. 2723 2724* X3J13 writeup <COMPUTE-APPLICABLE-METHODS:GENERIC> is implemented: 2725 COMPUTE-APPLICABLE-METHODS is now a generic function. 2726 2727* X3J13 writeup <CONDITION-SLOTS:HIDDEN> is implemented: Predefined condition 2728 types have their own private slot names. 2729 2730* X3J13 vote <57> = writeup <DEFSTRUCT-SLOTS-CONSTRAINTS-NAME:DUPLICATES-ERROR> 2731 is implemented: Different slots in a structure cannot have names whose 2732 SYMBOL-NAME are equal. 2733 2734* X3J13 writeup <CONS-TYPE-SPECIFIER:ADD> is implemented: 2735 New type specifier (CONS car-type cdr-type). 2736 2737* X3J13 writeup <DEFMACRO-BLOCK-SCOPE:EXCLUDES-BINDINGS> is implemented: 2738 The implicit BLOCK generated by DEFMACRO and DEFTYPE encloses only the 2739 body forms, not the forms occurring in the lambda list. 2740 2741* X3J13 writeup <DEFSTRUCT-COPIER:ARGUMENT-TYPE> is implemented: 2742 New function COPY-STRUCTURE. 2743 2744* X3J13 writeup <JUN90-TRIVIAL-ISSUES:9> is implemented: 2745 New classes GENERIC-FUNCTION, STRUCTURE-OBJECT, CLASS, METHOD. Removed 2746 the type STRUCTURE. 2747 2748* X3J13 writeup <EVALHOOK-STEP-CONFUSION:X3J13-NOV-89> is implemented: 2749 Do not export EVALHOOK, APPLYHOOK, *EVALHOOK*, *APPLYHOOK* from package 2750 COMMON-LISP any more. 2751 2752* X3J13 writeup <MACRO-DECLARATIONS:MAKE-EXPLICIT> is implemented: NOTINLINE 2753 declarations of macros having special compiler treatment are now respected. 2754 2755* X3J13 writeups <DEFSTRUCT-PRINT-FUNCTION-INHERITANCE:YES> and 2756 <DEFSTRUCT-PRINT-FUNCTION-AGAIN:X3J13-MAR-93> are implemented: 2757 DEFSTRUCT accepts an option :PRINT-OBJECT, similar to :PRINT-FUNCTION, 2758 and each of these options causes a method on PRINT-OBJECT to be installed. 2759 2760* X3J13 writeup <SPECIAL-FORM-P-MISNOMER:RENAME> is implemented: New function 2761 SPECIAL-OPERATOR-P. The function SPECIAL-FORM-P still exists, but its use 2762 generates a compiler warning. 2763 2764* X3J13 writeup <FLOATING-POINT-CONDITION-NAMES:X3J13-NOV-89> is implemented: 2765 New condition types FLOATING-POINT-INEXACT, FLOATING-POINT-INVALID-OPERATION. 2766 2767* Fixed a bug: Reading objects in #n# syntax into typed structure slots gave 2768 an error if the structure's constructor was not compiled. 2769 Reported by Sam Steingold. 2770 2771* BUTLAST and NBUTLAST are now ANSI CL compliant: They signal an error if the 2772 argument is a dotted list of length 0. (Stupid.) 2773 2774* The macro WITH-OUTPUT-TO-STRING is now ANSI compliant. 2775 2776* Added FFI support for NetBSD/m68k. 2777 Thanks to Jörn Clausen <joern@techfak.uni-bielefeld.de>. 2778 2779* Use of the deprecated functions GENTEMP and SET now generates a compiler 2780 warning. 2781 2782* Stricter syntax checking for DO and DO*. 2783 2784* When CLOS:CALL-NEXT-METHOD is called with arguments, it is now checked that 2785 the set of applicable methods is the same as for the original arguments, in 2786 interpreted code only. 2787 2788* The CLX documentation now also exists in HTML format. 2789 Thanks to Gilbert Baumann <unk6@rz.uni-karlsruhe.de>. 2790 2791* The normal read-eval-print loop does not call (CLEAR-INPUT *STANDARD-INPUT*) 2792 any more. This means that under X11, cut and paste of multiple lines into 2793 an xterm running clisp now works. 2794 Suggested by Sam Steingold. 2795 2796* When opening socket servers, ignore EADDRINUSE errors coming from other 2797 sockets, in TIME_WAIT or CLOSE_WAIT state, hanging around on the port. 2798 Suggested by Don Cohen. 2799 2800* Fixed a bug: When *PRINT-PRETTY* = T, (PRINC #\Newline) often caused two 2801 newline characters to be output instead of a single one. 2802 2803* Fixed a bug: The sequence type functions refused to handle sequence types 2804 of the form ([SIMPLE-]ARRAY eltype 1). SUBTYPEP returned wrong results 2805 for type specifiers of the form ([SIMPLE-]ARRAY eltype n). 2806 2807* Fixed a bug: GET-MACRO-CHARACTER on a dispatch macro character does not 2808 result in an error any more. 2809 2810* Fixed a bug in ECASE, ETYPECASE, CCASE, CTYPECASE. 2811 These macros now accept T and OTHERWISE as keys. 2812 2813* Fixed a bug: OPEN did not accept type specifiers defined by DEFTYPE as 2814 :ELEMENT-TYPE argument. 2815 2816* Fixed a bug in the LOOP macro: Forms containing REPEAT clauses were 2817 executed too often in the presence of FOR-= clauses. 2818 2819* Fixed a bug: The SPACE macro returned a list of the form's values, instead 2820 of the values themselves. 2821 2822* Fixed a bug, implement X3J13 writeup <PRINC-READABLY:X3J13-DEC-91>: 2823 When *PRINT-READABLY* = T, (PRINC string) caused the string to be output 2824 in double-quotes instead of literally. 2825 2826* X3J13 writeup <IGNORE-USE-TERMINOLOGY:VALUE-ONLY> is implemented: 2827 A "variable is used despite of IGNORE declaration" warning is not emitted 2828 any more for a variable that is only assigned to and not used for value. 2829 Suggested by Pierpaolo Bernardi. 2830 2831* Fixed a bug in function FILE-AUTHOR on Win32. 2832 2833* Fixed a bug: CLISP was unable to determine the user's homedir in 2834 certain (obscure) circumstances. 2835 2836* Do not warn anymore if someone modifies one of the standard generic 2837 functions of CL like PRINT-OBJECT and INITIALIZE-INSTANCE. 2838 2839Portability 2840----------- 2841 2842* Added AmigaOS support for the socket functions. It's not perfect, but 2843 sufficient for writing socket clients. 2844 Thanks to Jörg Höhle. 2845 2846* Port to Win32 using msvc5. (Previously only msvc4 was supported.) 2847 2848* Dropped support for pre-ANSI-C compilers. 2849 2850* Updated support for EMX. 2851 2852* Dropped support for EMX versions older than 0.9c. 2853 2854* Added support for PowerPC running MkLinux. 2855 2856* Removed (incomplete) support for MS Windows 3.1. 2857 2858Other modifications 2859------------------- 2860 2861* `clisp-link' has a new command `run', to run a linking set with some 2862 modules loaded. If CLISP has been configured with option 2863 --with-dynamic-modules, this is much faster than constructing a 2864 temporary linking set. 2865 Suggested by Gilbert Baumann <unk6@rz.uni-karlsruhe.de>. 2866 2867* Compiling IFs with no else part now produce better code (Jörg Höhle). 2868 2869* Speed up I/O to *STANDARD-INPUT*, *STANDARD-OUTPUT* and *TERMINAL-IO*: 2870 If standard input is redirected from a file, the input side of *TERMINAL-IO* 2871 will be buffered. If standard output is redirected to a file, the output 2872 side of *TERMINAL-IO* will be buffered. 2873 2874* Dropped the STDWIN library. 2875 2876* Added a new type encoding scheme which allows all address ranges from 2877 0x00000000 to 0x7FFFFFFF to be used. This should make porting to some 2878 systems easier. 2879 2880* Added bindings to libc for Linux with libc6 (aka glibc 2.0). 2881 2882* Miscellaneous documentation updates. 2883 2884 28852.20.1 (6 December 1997) 2886======================== 2887 2888User visible changes 2889-------------------- 2890 2891* Fixed a bug which could cause a crash when Ctrl-C was pressed during heap 2892 allocation on i386. 2893 2894Other modifications 2895------------------- 2896 2897* The implementation notes now also exist in HTML format. 2898 2899 29002.20 (25 September 1997) 2901======================== 2902 2903User visible changes 2904-------------------- 2905 2906* X3J13 vote <53> is implemented: DEFSTRUCT BOA constructors can have &KEY 2907 arguments. 2908 2909* X3J13 vote <40> is partially implemented: New variable *READ-EVAL*. 2910 2911* X3J13 vote <150> is implemented: (READTABLE-CASE readtable) can now have 2912 the value :INVERT. 2913 2914* MAKE-PACKAGE and IN-PACKAGE accept a keyword argument :CASE-SENSITIVE. 2915 Similarly, DEFPACKAGE accepts an option :CASE-SENSITIVE. When its value is 2916 non-NIL, the package will be case sensitive, i.e. the reader will not 2917 case-convert symbol names before looking them up or creating them in this 2918 package. The package names are still subject to (READTABLE-CASE *READTABLE*), 2919 though. 2920 2921* X3J13 vote <157> is implemented: ROOM accepts an optional argument with 2922 default value :DEFAULT. 2923 2924* New macro SPACE. (SPACE form) evaluates form and prints information about 2925 the memory allocations caused by this evaluation. 2926 2927* The spanish translation is now 100% complete. Thanks to Carlos Linares. 2928 2929* DESCRIBE of a structure now displays the structure's slots. 2930 2931* The reader now accepts the syntax #\^A ... #\^Z for the ASCII control 2932 characters. 2933 2934* Fixed a CLOS bug: &ALLOW-OTHER-KEYS in lambda lists of INITIALIZE-INSTANCE 2935 now disables the validity checking of corresponding MAKE-INSTANCE calls. 2936 Thanks to Matthias Lindner <matthias@intellektik.informatik.th-darmstadt.de>. 2937 2938* Fixed a bug: The type REAL is now accepted as a declaration specifier. 2939 2940* Fixed a bug: When using GNU gettext, the LOCALIZED function always returned 2941 the value corresponding to language ENGLISH, and the interactive conflict 2942 resolution of some IMPORT/EXPORT package operations aborted with an internal 2943 error. 2944 2945* Fixed a bug in the foreign function interface: call-ins did not work on 2946 some platforms. 2947 Thanks to Matthias Lindner <matthias@intellektik.informatik.th-darmstadt.de>. 2948 2949* Fixed a bug: Calling the function SOCKET-SERVICE-PORT with a non-string 2950 argument caused a crash. 2951 2952* Fixed two bugs which could cause a crash when a GC occurred during an 2953 IN-PACKAGE or during a pathname operation (DOS, OS/2, Win32 versions only). 2954 2955* Added image support to the clx/new-clx module. 2956 Thanks to Gilbert Baumann <gilbert@ma2s2.mathematik.uni-karlsruhe.de>. 2957 2958Portability 2959----------- 2960 2961* More Win32 support: stack overflow handling, foreign function interface, 2962 more robust memory management. 2963 2964* Added support for Win32 (WinNT and Win95), using Borland C++. 2965 2966* Fixed a compilation error when compiling for sparcv8. 2967 Thanks to Hans Adams <adamsh@server.ecomp.de>. 2968 2969* Updated support for Solaris/x86. 2970 Thanks to Lutz Euler <euler@lavielle.com>. 2971 2972Other modifications 2973------------------- 2974 2975* Reduced the number of conses allocated by calling APPLY on a function with 2976 both &KEY and &REST. 2977 Thanks to Jörg Höhle. 2978 2979* The CLX documentation can now be viewed in ghostview. 2980 Thanks to Karl M. Hegbloom <karlheg@inetarena.com>. 2981 2982 29832.19 (7 August 1997) 2984==================== 2985 2986User visible changes 2987-------------------- 2988 2989* Two new add-on modules: 2990 clx/new-clx: Fast Common Lisp to X11 interface. Written by 2991 Gilbert Baumann <gilbert@ma2s2.mathematik.uni-karlsruhe.de>. 2992 clx/mit-clx: Classic Common Lisp to X11 interface. 2993 2994* (DRIBBLE filename) now appends to the given file instead of overwriting it. 2995 2996* Fixed a bug: Platform dependent constants are not inlined in .fas files any 2997 more. 2998 2999* Fixed a bug: Binding *PRINT-PRETTY* to NIL inside a PRINT-OBJECT method or 3000 inside a structure's print-function could result in undefined behaviour. 3001 Thanks to Don Cohen <don@nichimen.com>. 3002 3003* Fixed a bug: For x a float, (= 0 x) and (EQUALP 0 x) could result in 3004 undefined behaviour. 3005 Thanks to Don Cohen <don@nichimen.com>. 3006 3007* Fixed a bug: The error message issued by CHECK-TYPE was wrong. 3008 3009* Fixed a bug: Calling (DRIBBLE pathname) after (DRIBBLE) did not work. 3010 Thanks to Art Nuzzo <artn@bs724.comm.mot.com>. 3011 3012* Fixed a bug: The WITH-STANDARD-IO-SYNTAX macro caused *PACKAGE* to be bound 3013 to an invalid value. 3014 3015* Fixed two bugs in the GC (one in the generational GC, one in the 3016 non-generational GC). 3017 Big thanks to Marcus Daniels. 3018 3019* Fixed a bug: Printing socket streams created by SOCKET-ACCEPT could result 3020 in an error or an endless loop. 3021 3022Portability 3023----------- 3024 3025* Added support for Win32 (WinNT and Win95), using Microsoft Visual C++. 3026 3027* Added support for Cygwin32 version 18 (Unix emulation on WinNT or Win95). 3028 3029* Added support for GNU 0.2 (the Hurd). Thanks to Marcus Daniels. 3030 3031Other modifications 3032------------------- 3033 3034* "clisp" can now be called with "-" as argument. The standard input is then 3035 executed by a read-eval-print loop without prompt, while the remaining 3036 arguments will be assigned to the variable *ARGS*. 3037 3038* Overall speedup by 13% on i386. 3039 3040 30412.18 (3 May 1997) 3042================= 3043 3044User visible changes 3045-------------------- 3046 3047* X3J13 vote <182> is now fully implemented: A LET/LET*/COMPILER-LET binding 3048 specification may now be a list of length 1, without initial value. 3049 Thanks to Gilbert Baumann <gilbert@ma2s2.mathematik.uni-karlsruhe.de>. 3050 3051* X3J13 vote <78> is now fully implemented: FLET, LABELS, MACROLET establish 3052 an implicit BLOCK. 3053 3054* X3J13 vote <100> is implemented: Hash tables with test function EQUALP. 3055 3056* X3J13 vote <131> is partially implemented: #P reader macro for pathnames. 3057 3058* The MULTIPLE-VALUE-BIND macro no longer allows lists as variable 3059 specifications, only symbols. 3060 Thanks to Gilbert Baumann <gilbert@ma2s2.mathematik.uni-karlsruhe.de>. 3061 3062* DEFCLASS which changes a class is now allowed and generates a warning. 3063 Since UPDATE-INSTANCE-FOR-REDEFINED-CLASS is not supported, it is your 3064 responsibility to not use the old instances afterwards. 3065 Suggested by Brian Dennis <xjam@CS.Berkeley.EDU> and Tobias Kunze 3066 <tkunze@cmsgia.Stanford.EDU>. 3067 3068* The TIME macro now outputs to *TRACE-OUTPUT* instead of *STANDARD-OUTPUT*. 3069 Thanks to Nathan Sidwell <nathan@bristol.st.com>. 3070 3071* When the argument of the function TRANSLATE-LOGICAL-PATHNAME is a string, 3072 it is now interpreted as a logical pathname string. Previously, it was 3073 coerced to a pathname through the function PATHNAME, yielding a physical 3074 pathname. 3075 3076* CLISP now supports more than the three predefined user-interface languages. 3077 New macros DEFLANGUAGE, DEFINTERNATIONAL, DEFLOCALIZED. New function 3078 LOCALIZED. The macros ENGLISH, DEUTSCH, FRANCAIS now work only for strings. 3079 Removed the macro LANGUAGE-CASE. 3080 The implementation uses the GNU gettext library. 3081 Thanks to Ulrich Drepper and Marcus Daniels. 3082 3083* New user-interface language ESPANOL. 3084 Thanks to Carlos Linares López <clinares@delicias.dia.fi.upm.es> who has 3085 translated about 55% of CLISP's messages to Spanish. 3086 3087* EQUALP now descends structures (but not CLOS instances!) on all platforms, 3088 as requested by X3J13 vote <71>. 3089 3090* The EXIT-ON-ERROR macro now also exits when a Ctrl-C interrupt occurs. 3091 Thanks to Roger Kehr <kehr@iti.informatik.th-darmstadt.de>. 3092 3093* The initial value of *LOAD-PATHS* on Unix is now (#"./" "~/lisp/**/") 3094 instead of (#"./" #"./**/" "~/**/"). To be customized in config.lsp. 3095 3096* New variable *LOAD-COMPILING*, which provides the default value for the 3097 :COMPILING keyword of function LOAD. The initial value of *LOAD-COMPILING* 3098 can be specified by a command line option. 3099 3100* Fixed a bug: (VALUES-LIST '()) often returned one value. 3101 Thanks to Gilbert Baumann <gilbert@ma2s2.mathematik.uni-karlsruhe.de>. 3102 3103* Fixed a bug in the compiler: When optimizing (OR T form), the compiler 3104 could abort with an error message. 3105 Thanks to Nathan Sidwell <nathan@bristol.st.com>. 3106 3107* Fixed a bug in the DEFSTRUCT macro which caused the compiler to issue 3108 an error message when compiling a structure definition containing a slot 3109 with a constant, non-NIL initializer. 3110 Thanks to Matthias Lindner <lindner@forwiss.uni-erlangen.de>. 3111 3112* Fixed a bug in the DEFCLASS macro which caused DEFCLASS and DEFINE-CONDITION 3113 to reject the :DOCUMENTATION class option. 3114 Thanks to Don Cohen <donc@isi.edu>. 3115 3116* Fixed a bug: The use of type specifiers of the form 3117 (FUNCTION argument-types result-type) 3118 within THE, ETHE, LOOP and DEFSTRUCT forms could lead to errors. 3119 Thanks to Marty Shannon <mshannon@i-2000.com>. 3120 3121* Fixed two bugs in the DRIBBLE function: After calling (DRIBBLE pathname) 3122 followed by (DRIBBLE), *DEBUG-IO* referred to an unwritable stream. 3123 Calling (DRIBBLE pathname) from within a break loop caused some of the 3124 output to be logged twice. 3125 3126* Fixed a bug in the expansion of deeply nested backquotes. 3127 Thanks to S. Wotherspoon <spoon@hilbert.maths.utas.edu.au>. 3128 3129* Fixed a bug in the LOOP macro: Stepping for FOR-AS-= clauses 3130 (LOOP ... {FOR|AS} var = form1 THEN form2 ...) could be executed in the 3131 wrong order if form1 is constant and form2 is non-constant. 3132 Thanks to Russell Senior <seniorr@teleport.com>. 3133 3134* Fixed a bug in /= : When called with more than two arguments, only the 3135 first two arguments were compared; the remaining arguments were ignored. 3136 Thanks to J. V. Needham <jv@rdk840.dfci.harvard.edu>. 3137 3138* Fixed a bug in EQUAL and EQUALP: displaced strings were not compared 3139 correctly. 3140 3141* Fixed a bug in EXPT: For x a (COMPLEX RATIONAL) and y = m/2^n, (EXPT X Y) 3142 actually returned x ^ (m/2^(n+32)) instead of x ^ (m/2^n). 3143 3144* Fixed a bug in TRUENAME on Unix: If "aa.bb" is a symbolic link to "cc", 3145 (TRUENAME "aa.bb") returned "cc.bb" instead of "cc". 3146 3147* Fixed a bug in the management of add-on modules: On some platforms, 3148 GC in memory images containing add-on modules always crashed. 3149 3150* Fixed a bug in the generational GC on i386, rs6000, alpha: In some cases, 3151 FFI objects in memory could cause the first "small" garbage collection to 3152 fail. 3153 Thanks to Dr. Werner Fink <werner@suse.de>. 3154 3155* Fixed a bug in the printing routine for SOCKET-SERVER objects. 3156 Thanks to Alexey Goldin <goldin@spot.uchicago.edu> and Marcus Daniels. 3157 3158Portability 3159----------- 3160 3161* The core of CLISP can now be compiled with a C++ compiler if no C compiler 3162 is available (without readline library, FFI or modules). 3163 3164* Added support for Mips processors in 64-bit mode. 3165 3166* Updated support for Linux 2.0. 3167 3168* Support for immutable objects now works on Linux/ELF. It did already work 3169 on Linux/a.out. 3170 3171* Updated Amiga support. Thanks to Jörg Höhle <Joerg.Hoehle@gmd.de>. 3172 3173* Updated Acorn support. Thanks to Peter Burwood <clisp@arcangel.dircon.co.uk>. 3174 3175* Updated OS/2 support. Thanks to Jörg Diederich <J_Diederich@herlab.ruhr.de>. 3176 3177* Updated support for Solaris/x86. Thanks to Marty Shannon <mjs@tiaa-cref.org>. 3178 3179* Fixed a bug which could cause the readline completion to dump core on HP-UX. 3180 3181* Fixed a bug relating to the read-eval-print loop's return point on some 3182 platforms. Thanks to Peter Burwood <clisp@arcangel.dircon.co.uk>. 3183 3184* Removed an incompatibility between SPARC/Sun4 and UltraSPARC memory images. 3185 Found by Martin Ginkel <ginkel@iik.cs.uni-magdeburg.de>. 3186 3187* Removed support for AmigaOS versions < 2.04. 3188 3189Other modifications 3190------------------- 3191 3192* New "makemake" option --with-wide causes normal and wide-mode binaries to 3193 be built and distributed simultaneously. New command-line option -W 3194 for choosing the wide-mode binaries instead of the normal binaries. 3195 3196* On Unix, "clisp" is now an executable instead of a shell script. 3197 3198* "clisp" can now be called with a Lisp file as argument. The remaining 3199 arguments will be passed to the Lisp program in the variable *ARGS*. 3200 On Unix, you can thus make Lisp programs executable by putting 3201 "#!/usr/local/bin/clisp" in the first line and doing a "chmod a+x". 3202 3203* The read-eval-print loop now calls FORCE-OUTPUT after outputting the prompt. 3204 Thanks to Jörg Höhle <Joerg.Hoehle@gmd.de>. 3205 3206* Support for immutable objects now also works in the WIDE tagging scheme. 3207 3208* Reduced the startup time by 20-30%. 3209 3210 32112.17 (21 July 1996) 3212=================== 3213 3214Important note 3215-------------- 3216 3217* Changed bytecode format. All .fas files generated by previous CLISP versions 3218 are invalid and must be recompiled. 3219 3220User visible changes 3221-------------------- 3222 3223* X3J13 vote <72> is conditionally implemented: Objects other than symbols, 3224 lists, numbers, characters, string, bit-vectors are now self-evaluating if 3225 *PACKAGE* uses the COMMON-LISP package. 3226 3227* The package CLOS is now among the default use list of a new package. 3228 (USE-PACKAGE "CLOS") is not needed any more. To use PCL, you now need 3229 to (UNUSE-PACKAGE "CLOS") explicitly. 3230 3231* The bytecode format is now platform independent. As a consequence, 3232 compiled functions can be printed readably when *PRINT-READABLY* = T. 3233 3234* Built-in function objects (SUBRs) are now printed readably when 3235 *PRINT-READABLY* = T, instead of signaling an error. 3236 3237* Added a <c-type>, C-PTR-NULL to the FFI. C-PTR-NULL will convert 3238 NIL objects into NULL pointers (so that type conflicts can be avoided). 3239 3240* Socket streams are implemented. New functions SOCKET-SERVER, 3241 SOCKET-SERVER-CLOSE, SOCKET-SERVER-PORT, SOCKET-WAIT, SOCKET-ACCEPT, 3242 SOCKET-CONNECT, SOCKET-STREAM-HOST, SOCKET-STREAM-PORT, SOCKET-SERVICE-PORT, 3243 SOCKET-STREAM-PEER-HOST. 3244 See <http://clisp.org/impnotes/socket.html> for details. 3245 Thanks to Marcus Daniels <marcus@sysc.pdx.edu> and 3246 Marco Ramoni <M.Ramoni@open.ac.uk>. 3247 3248* Pipe streams now support binary I/O. 3249 3250* MAKE-INSTANCE now also works for DEFSTRUCT classes, and DEFSTRUCT classes 3251 can now be subclassed via DEFCLASS with option :METACLASS STRUCTURE-CLASS. 3252 Suggested by Manuel Kolp <kolp@qant.ucl.ac.be>. 3253 3254* User defined methods on NO-APPLICABLE-METHOD now have a chance for a 3255 corrective action. Thanks to Mark Thomas <thommark@access.digex.net>. 3256 3257* APROPOS and DESCRIBE now tell you about symbols which name a type or class. 3258 3259* During directory search, symbolic link loops are now ignored instead 3260 of resulting in an error. Thanks to Dan Stanger. 3261 3262* Fixed a CLOS bug: REMOVE-METHOD did not work. 3263 Thanks to Roger Kehr <kehr@iti.informatik.th-darmstadt.de>. 3264 3265* Fixed a bug in the compiler: A (MULTIPLE-VALUE-SETQ vars valform) 3266 or (MULTIPLE-VALUE-BIND vars valform ...) form was miscompiled if 3267 valform is known to produce a single value. 3268 Thanks to Paul Graham <pg@das.harvard.edu>. 3269 3270* Fixed at least two bugs in the LOOP macro: FOR-AS-ACROSS clauses could 3271 result in AREF signaling an out-of-bounds error at the end of the vector. 3272 Initialisations for FOR-AS-= clauses could be executed in the wrong order. 3273 3274* Fixed a bug: the functions ENCODE-UNIVERSAL-TIME and DECODE-UNIVERSAL-TIME 3275 computed a wrong DST flag for time values between (T - 2h) and T, where 3276 T denotes a DST switch time. 3277 3278* Fixed two bugs in the foreign function interface: multi-dimensional arrays 3279 and floating point numbers with value 0.0 were not correctly passed from 3280 "foreign land" to "Lisp land". Thanks to Ken Olum <kdo@mit.edu>. 3281 3282* Fixed a bug in the foreign function interface: call-ins which return 3283 structures or unions would not compile correctly. Thanks to Michael Stoll. 3284 3285* Fixed a bug: On Solaris, the function SYSTEM sometimes reported exit 3286 status 0 although the command had failed. 3287 Thanks to Brian F. Dennis <xjam@cs.Berkeley.edu>. 3288 3289* Fixed a bug: LOGTEST did not work correctly if both arguments were bignums. 3290 3291* Fixed a bug in the floating point number printing routine: 3292 In rare cases, a number was printed with more digits than necessary 3293 (without, however, violating the print-read consistency). For example, 3294 2.1416s29 printed as 2.14159s29, and 3.002618f-31 printed as 3.0026179f-31. 3295 3296* Fixed a bug in ATAN: (ATAN y 0) with y < 0 returned pi/2 instead of -pi/2. 3297 3298* Fixed a bug in XGCD which caused the results to be wrong with a small 3299 probability, for example in the case (XGCD 77874422 32223899). 3300 3301Portability 3302----------- 3303 3304* FreeBSD/NetBSD patches and compilation notes. 3305 Thanks to Douglas Crosher <dtc@stan.xx.swin.oz.au>. 3306 3307* Added support for SUNWspro cc 3.0.1 on Sparc. 3308 3309* Updated support for Ultrix. 3310 3311* Updated support for NeXTstep version 3.3. 3312 Thanks to Robert Murphy <robert.murphy@yale.edu>. 3313 3314* Updated support for SINIX. Thanks to Michael Becker <mb12@coconet.de>. 3315 3316* Fixed a bug in the conversion of double-float numbers from "foreign land" 3317 to "Lisp land" on DEC Alpha. Thanks to Ken Olum <kdo@mit.edu>. 3318 3319* Fixed a bug in the implementation of LISTEN on Irix: CLISP went into a 3320 `function call not implemented' OS error loop. Thanks to Marcus Daniels. 3321 3322* Fixed a signal handling bug on some versions of SunOS 4: Strange things 3323 could happen in a break loop. 3324 3325* The `configure' script now supports the --srcdir, --prefix and --exec-prefix 3326 options. 3327 3328* Removed support for Atari ST/TT running TOS. 3329 3330Other modifications 3331------------------- 3332 3333* The compiler now recognizes more function calls as inlinable: Cases like 3334 (FUNCALL (LAMBDA ...) ...), (DECLAIM (INLINE F)) (MAPCAR #'F ...) 3335 are now compiled as inline function calls. Previously you had to write 3336 (FUNCTION (LAMBDA ...)) explicitly. Suggested by Jörg Höhle. 3337 3338* "makemake" now supports the --srcdir, --prefix and --exec-prefix options. 3339 3340* Added a testsuite for part of CLOS. Thanks to Christian Jullien. 3341 3342* Miscellaneous documentation updates. 3343 3344 33452.16 (23 June 1995) 3346=================== 3347 3348Important note 3349-------------- 3350 3351* Changed bytecode format. All .fas files generated by previous CLISP versions 3352 are invalid and must be recompiled. 3353 3354User visible changes 3355-------------------- 3356 3357* X3J13 vote <106> is implemented: LAST has an optional argument. 3358 Thanks to Pierpaolo Bernardi. 3359 3360* X3J13 vote <87> is implemented: New function COMPLEMENT. 3361 Thanks to Pierpaolo Bernardi. 3362 3363* X3J13 vote <40> is partially implemented: New macro WITH-STANDARD-IO-SYNTAX. 3364 Thanks to Pierpaolo Bernardi. 3365 3366* X3J13 vote <98> is partially implemented: New macro WITH-HASH-TABLE-ITERATOR. 3367 Thanks to Pierpaolo Bernardi. 3368 3369* X3J13 vote <97> is implemented: New functions HASH-TABLE-REHASH-SIZE, 3370 HASH-TABLE-REHASH-THRESHOLD, HASH-TABLE-SIZE, HASH-TABLE-TEST. 3371 Thanks to Pierpaolo Bernardi. 3372 3373* X3J13 votes <69> and <70> are implemented: New declaration DYNAMIC-EXTENT. 3374 3375* The dpANS macro LAMBDA is implemented. 3376 3377* The dpANS declaration IGNORABLE is implemented. 3378 3379* The dpANS function CONSTANTLY is implemented. Thanks to Pierpaolo Bernardi. 3380 3381* Better syntax checking for the CASE macro. Thanks to Pierpaolo Bernardi. 3382 3383* The user interface language may be chosen through the environment variable 3384 LANG as well. 3385 3386* The pretty printer now indents lists spanning more than one line by two 3387 spaces, instead of one. New variable *PRINT-INDENT-LISTS*. 3388 3389* *PRINT-PRETTY* is now initially T. 3390 3391* Foreign function interface: New foreign type constructor FFI:C-ARRAY-MAX, 3392 implements zero-terminated arrays of bounded size. 3393 3394* On Unix, 8-bit characters are legal in pathnames if the operating system 3395 accepts them. 3396 3397* On DOS, #\Newline is converted to CR/LF when doing character output to 3398 unbuffered file streams (referring to special files). 3399 3400* Fixed a bug in the interpreter and compiler: A MULTIPLE-VALUE-SETQ form 3401 which assigns to a symbol macro expanded to a wrong form; compiling it 3402 produced a warning. Thanks to Pierpaolo Bernardi. 3403 3404* Fixed a bug in the compiler: Some CASE form with duplicate keys, when 3405 compiled, chose the wrong clause to be executed. 3406 Thanks to Pierpaolo Bernardi. 3407 3408* Fixed a bug in the #+/#- reader macros. (LIST #+FOO #-BAR 1 2 3) now 3409 returns (2 3), not (3). 3410 3411* Fixed a bug in LOG: (LOG x^n x^m), where n, m are integers, |m| > 1, and 3412 x is a rational number /= 1, now correctly returns n/m. Previously, 3413 (LOG 2 4) returned 1/0. 3414 3415* Fixed a CLOS bug: Using the :DOCUMENTATION option in DEFGENERIC declarations 3416 for function names of the form (SETF symbol) signalled an error. 3417 Thanks to Pierpaolo Bernardi. 3418 3419* Fixed a bug in DEFSETF: An IGNORE declaration for the store variable had 3420 no effect. Thanks to Pierpaolo Bernardi. 3421 3422Portability 3423----------- 3424 3425* Added support for Linux/ELF. Thanks to Marcus Daniels. 3426 3427* Added support for Solaris/x86. Thanks to Marty Shannon. 3428 3429* On Solaris, LISTEN and READ-CHAR-NO-HANG did not work on the terminal stream 3430 if standard input was redirected to come from a file. 3431 3432* On OS/2, consider the virtual directory \PIPE\ as existent. 3433 3434Other modifications 3435------------------- 3436 3437* A couple of bug fixes and new functions in the STDWIN package. 3438 Thanks to Pierpaolo Bernardi. 3439 3440* The structure of external modules has changed a bit. 3441 3442* Miscellaneous documentation updates. 3443 3444 34452.15 (25 April 1995) 3446==================== 3447 3448User visible changes 3449-------------------- 3450 3451* Michael Stoll has written a graphical user interface for CLISP under 3452 NeXTstep. 3453 3454* Added a foreign language module WILDCARD for wildcard matching. 3455 3456* Added a foreign language module REGEXP for Unix-style regular expression 3457 matching and searching. 3458 3459* X3J13 vote <94> is implemented: Calling GENSYM has no side effects except 3460 incrementing the counter. New variable *GENSYM-COUNTER*. 3461 3462* New macro FORMATTER converts a FORMAT control string to a function. 3463 3464* Some FORMAT fixes: 3465 + X3J13 vote <81> is implemented: The FORMAT ~:^ directive is more useful. 3466 Warning: Old style "~:^" directives need to be converted to "~#:^". 3467 + X3J13 vote <82> is implemented: The FORMAT ~D, ~B, ~O, ~X, ~R directives 3468 accept an optional comma-interval parameter. 3469 + X3J13 vote <84> is implemented: FORMAT ~C outputs characters with no bits 3470 as if by WRITE-CHAR. 3471 + Handling of ~^ within the FORMAT ~? directive. 3472 3473* X3J13 vote <167> is implemented: New types FILE-STREAM, SYNONYM-STREAM, 3474 BROADCAST-STREAM, CONCATENATED-STREAM, TWO-WAY-STREAM, ECHO-STREAM, 3475 STRING-STREAM. New functions OPEN-STREAM-P, SYNONYM-STREAM-SYMBOL, 3476 BROADCAST-STREAM-STREAMS, CONCATENATED-STREAM-STREAMS, 3477 TWO-WAY-STREAM-INPUT-STREAM, TWO-WAY-STREAM-OUTPUT-STREAM, 3478 ECHO-STREAM-INPUT-STREAM, ECHO-STREAM-OUTPUT-STREAM. 3479 3480* New condition type PRINT-NOT-READABLE. 3481 New function PRINT-NOT-READABLE-OBJECT. 3482 3483* New function FINALIZE. (FINALIZE object function) has the effect that 3484 function will be called when object is being garbage collected. 3485 3486* DRIBBLE now also redirects *ERROR-OUTPUT*, *TRACE-OUTPUT*, *QUERY-IO*, 3487 *DEBUG-IO* if they refer to *TERMINAL-IO*. 3488 3489* Calling SYMBOL-VALUE on a symbol defined as global symbol macro now returns 3490 the value of the expansion. New function SYMBOL-MACRO-EXPAND. 3491 3492* Add FFI to the *FEATURES* if the foreign language interface is present. 3493 3494* Fixed a bug: An IGNORE declaration for a macro's &ENVIRONMENT argument now 3495 has an effect. 3496 3497* Fixed a couple of bugs in the foreign language interface: Passing zero size 3498 arrays did not work, parameters with mode :OUT did not work on SPARC and 3499 HP-PA, and some error messages were deficient. 3500 3501* Fixed a bogus error message in SET-DISPATCH-MACRO-CHARACTER. 3502 3503Portability 3504----------- 3505 3506* Fixed a couple of building problems relating to the foreign language 3507 interface (missing `mark_fp_invalid' and `pr_hex8', missing makefile 3508 dependencies, support for --with-dynamic-modules, warnings when compiling 3509 user2.lsp and foreign1.lsp). 3510 3511* Fixed a building problem: Not all C compilers accept casts in constant 3512 expressions used as initializers, e.g. gcc-2.5.8. 3513 3514* Foreign function interface: Fixed a couple of possible bugs in the low-level 3515 foreign function call routine for i386/486/586, m680x0, SPARC CPUs. 3516 Thanks to Jörg Höhle. 3517 3518* Small fixes for SCO. 3519 3520* Added a utility "hln" for making hard links. Needed for "make distrib"; 3521 Solaris "ln" does not make a hard link if a symbolic link is involved. 3522 3523* On some Unix systems, use "uname -m", not "arch", to determine 3524 (MACHINE-TYPE) and (MACHINE-VERSION). 3525 3526* More support for BSDI 1.0, AIX, HP-UX, Solaris. 3527 3528* Changed STDWIN so that it compiles under X11R6. 3529 3530Other modifications 3531------------------- 3532 3533* Speed up compiled calls to FORMAT with literal control string by use of 3534 FORMATTER. 3535 3536* Miscellaneous documentation updates. 3537 3538 35392.14 (4 April 1995) 3540=================== 3541 3542User visible changes 3543-------------------- 3544 3545* The initial value of *PACKAGE* can be specified by a command line option. 3546 3547* X3J13 vote <6> is implemented: New place ROW-MAJOR-AREF. 3548 3549* X3J13 vote <126> is implemented: New function DELETE-PACKAGE. 3550 3551* X3J13 vote <14> is implemented: Closing a synonym stream does not close 3552 its constituent stream. 3553 3554* Foreign language interface for C and ANSI C. New package FFI. New macros 3555 FFI:DEF-C-TYPE, FFI:DEF-C-VAR, FFI:DEF-C-CALL-OUT, FFI:DEF-C-CALL-IN, 3556 FFI:DEF-C-ENUM, FFI:DEF-C-STRUCT, FFI:DEF-CALL-OUT, FFI:DEF-CALL-IN, 3557 FFI:ELEMENT, FFI:DEREF, FFI:SLOT, FFI:CAST, FFI:TYPEOF, FFI:SIZEOF, 3558 FFI:BITSIZEOF. 3559 This currently works only on Unix and only with the CPUs 3560 i386/486/586, m680x0, Mips, SPARC, DEC Alpha, HP-PA, RS/6000. 3561 Warning: (COMPILE-FILE "filename.lsp") now overwrites the file "filename.c". 3562 3563* New macros MUFFLE-CERRORS and APPEASE-CERRORS. During their execution, 3564 continuable errors are handled by the function CONTINUE. MUFFLE-CERRORS 3565 does this silently, APPEASE-CERRORS prints the error as a warning. 3566 3567* New macro EXIT-ON-ERROR. During its execution, non-continuable errors 3568 cause CLISP to exit with error status. 3569 3570* The function ED, when asked to edit a non-existent file, now creates that 3571 file instead of signaling an error. 3572 3573* When a non-absolute pathname is specified for the -o command line option 3574 (destination file of a compilation), it is interpreted as relative to the 3575 current directory, not relative to the source file of the compilation. 3576 3577* The readline library now uses the last column of the screen if the terminal 3578 is an xterm, for example. Work done by Chet Ramey. 3579 3580* Fixed two bugs in the LOOP macro: FOR-AS-ACROSS clauses could result in AREF 3581 signaling an out-of-bounds error at the end of the vector. Initialisations 3582 for FOR-AS-= clauses could be executed in the wrong order. 3583 3584* Fixed a bug in the compiler which caused LOAD-TIME-VALUE forms to be 3585 evaluated at compile time. 3586 3587* Fixed a bug in the debugger: Choosing a restart Rnnn always invoked the 3588 last restart listed, not the chosen one. 3589 3590* Fixed a bug: (CLOSE *TERMINAL-IO*) signals an error again. 3591 3592* On DOS and OS/2, the Lisp reader now treats Ctrl-Z as whitespace. 3593 3594* The -I command line option now tells the readline library to handle the Tab 3595 character as normal self-inserting character. 3596 3597* Unix version only: DISASSEMBLE can display machine instructions, provided 3598 that GNU gdb is present. 3599 3600Portability 3601----------- 3602 3603* Updated support for EMX. 3604 3605* Fixed a bug which caused a preprocessor error on SunOS and OSF/1. 3606 3607* Small fixes for Sinix and SCO. 3608 3609* Removed support for Coherent. 3610 3611Other modifications 3612------------------- 3613 3614* Generational garbage collection now also works on IRIX 5.2. 3615 3616* Generational garbage collection and support for immutable objects do not 3617 exclude each other any more. 3618 3619* Speed up the bytecode interpreter by about 2%. 3620 3621* Miscellaneous documentation updates. 3622 3623 36241 January 1995 3625============== 3626 3627CLISP now compiles and runs on 3628* microcomputers: 3629 * DOS 3630 * OS/2 2.0 3631 * MS Windows 3.1 3632 * Amiga 500-4000, Amiga OS 3633 * Atari ST/TT, TOS 3634 * Acorn ARM Risc PC, RISC OS 3635* Unix workstations: 3636 * PC, Linux 3637 * PC, USL SVR4 3638 * DEC Alpha AXP, OSF/1 3639 * Sun4, SunOS 4 or 5 3640 * HP9000/800, HP-UX 3641 * NeXT, NeXTstep 3.1 3642 * PC, NeXTstep 3.2 3643 * SGI Mips, Irix 4 or 5 3644 * SNI Mips, USL SVR4 3645 * DECstation 5000, Ultrix 4.2 3646 * IBM RS/6000, AIX 3.2 3647 * M88000 3648 * Sun386, SunOS 4 3649 * Sun3, SunOS 4 (?) 3650 * HP9000/300, HP-UX or NetBSD 3651 * Apple MacII, A/UX (?) 3652 * Amiga 3000, Amiga Unix 2.1 3653 * Sequent PTX 3654 * PC, 386BSD or NetBSD or BSDI/386 3655 * PC, UnixWare 3656 * PC, SCO (?) 3657 * PC, Coherent 4.0 3658 * Convex, ConvexOS 3659 * Atari ST/TT, MiNT 3660 3661Generational GC works on 3662 * PC, Linux 3663 * Sun4, SunOS 4 or 5 3664 * NeXT, NeXTstep 3.1 3665 * PC, NeXTstep 3.2 3666 * DEC Alpha AXP, OSF/1 3.0 3667 3668 36692.13.1 (1 January 1995) 3670======================= 3671 3672Important note 3673-------------- 3674 3675* Changed bytecode format.

New functions LOGICAL-PATHNAME, 3752 TRANSLATE-LOGICAL-PATHNAME, LOAD-LOGICAL-PATHNAME-TRANSLATIONS, 3753 COMPILE-FILE-PATHNAME. Thanks to Marcus Daniels. 3754 3755* X3J13 vote <132> is implemented: Synonym streams to file streams are 3756 allowed as pathnames. 3757 3758* Amiga version: SCREEN package is implemented. Thanks to Jörg Höhle. 3759 3760* The debugger emits some more messages to *DEBUG-IO*, not *ERROR-OUTPUT*. 3761 3762* (COERCE symbol 'FUNCTION) now works. 3763 3764* Fixed a bug in ENOUGH-NAMESTRING: In many cases, a relative directory 3765 specification was returned instead of an absolute directory specification. 3766 3767* Fixed a CLOS bug which caused (DEFCLASS FOO (STANDARD-OBJECT) ()) and 3768 (DEFINE-CONDITION FOO (CONDITION) ()) to signal errors. 3769 3770* Fixed a bug: In some situations, USE-PACKAGE reported a name conflict when 3771 there was none. 3772 3773* Fixed a bug: (READ-CHAR-NO-HANG stream nil eof-object) now signals an error 3774 if stream is not an input stream. Previously it returned eof-object. 3775 3776* Fixed a bug: On some Unix systems, (FINISH-OUTPUT *TERMINAL-IO*) signalled 3777 an error if standard output was redirected to a file. 3778 3779* (SQRT 0) now returns an integer 0 instead of a floating-point 0.0. 3780 3781* Readline library: Fixed a small problem with input prompts longer than the 3782 screen width. 3783 3784* Fixed three bugs in the built-in editor. One of them made the editor 3785 entirely unusable. 3786 3787Portability 3788----------- 3789 3790* Added some support for MS Windows. 3791 3792* On DOS, the readline library now handles the /!INPUTRC and history files 3793 correctly. 3794 3795* Some modification for the sake of gcc-2.6.1. 3796 3797Other modifications 3798------------------- 3799 3800* Generational garbage collection now also works on Linux (1.1.52 or newer). 3801 3802* On Unix, external modules written in C can be linked to CLISP without 3803 recompiling CLISP from source. For example, the STDWIN library. 3804 3805* Small fix: On some machines, some internal objects were being printed as 3806 #<SYSTEM-POINTER ...> instead of #<FRAME-POINTER ...>. 3807 3808* Miscellaneous documentation updates. 3809 3810 38112.12.1 (1 September 1994) 3812========================= 3813 3814User visible changes 3815-------------------- 3816 3817* The DEFCONSTANT warning about redefinition of a constant is also inhibited 3818 if the constant's new and old values are the same string (in the sense of 3819 EQUAL). Thanks to Marcus Daniels. 3820 3821* Unix version only: The daylight saving time flag of a time zone (eighth 3822 value of GET-DECODED-TIME and DECODE-UNIVERSAL-TIME) is now correct. 3823 3824Portability 3825----------- 3826 3827* Added support for Acorn ARM running RISCOS. Thanks to Peter Burwood. 3828 3829* Added support for NetBSD 1.0. Thanks to Douglas Crosher. 3830 3831* Updated support for EMX and DJGPP. 3832 3833* GNU malloc for HP-UX now works. 3834 3835 38362.12 (23 August 1994) 3837===================== 3838 3839User visible changes 3840-------------------- 3841 3842* X3J13 vote <64> is implemented: New macro DESTRUCTURING-BIND. 3843 3844* The function ED can now edit functions that have been entered in 3845 interpreted form even if they have later been compiled. 3846 3847* New function UNCOMPILE. (UNCOMPILE function-name) undoes the effect of 3848 (COMPILE function-name) if the function's definition had been entered 3849 in interpreted form. 3850 3851* The OPEN option :IF-EXISTS :RENAME-AND-DELETE now deletes the renamed 3852 file. Previously :RENAME-AND-DELETE was equivalent to :RENAME. 3853 3854* (LISP-IMPLEMENTATION-VERSION) returns a more precise version string. 3855 3856* Readline library: Completion of a function call with no arguments 3857 automatically adds the closing parenthesis. 3858 3859* Readline library: When a closing parenthesis is typed, the corresponding 3860 opening parenthesis is displayed. 3861 3862Portability 3863----------- 3864 3865* Added support for Convex. Thanks to Marcus Daniels. 3866 3867* Added support for SCO. Thanks to Cathy Bareiss and Marcus Daniels. 3868 3869* More NeXTstep support. 3870 3871* More Sinix support. Thanks to Manfred Weichel. 3872 3873* Updated support for AmigaOS. Thanks to Jörg Höhle. 3874 3875* Some modification for the sake of gcc-2.6. 3876 3877* Added GNU malloc. For HP-UX. 3878 3879* Added a bunch of character set conversion utilities. Covers the ASCII, 3880 ISO Latin-1, IBM PC, HP Roman8, NeXTstep and Atari ST character sets. 3881 3882* The `configure' script now prints its results. 3883 3884* Floating point computations on some CPUs (Sparc, HP-PA, M88000, RS/6000): 3885 Fixed some confusion between overflow and NaN and between underflow and zero. 3886 3887* Removed support for Atari Turbo-C (now known as PURE-C). 3888 3889Other modifications 3890------------------- 3891 3892* Copyright clarification. 3893 3894* Generational garbage collection. This works only for Unix implementations 3895 with powerful virtual memory management, currently only SunOS. 3896 3897* Improved virtual memory efficiency: 3898 - Memory model SPVW_PAGES: do not put a piece of management data into 3899 every page. 3900 - Memory model SPVW_BLOCKS: compact conses, do not shuffle them, so that 3901 they are kept sorted according to their age. 3902 - Memory model SPVW_PURE_BLOCKS: pages containing garbage are 3903 immediately freed. 3904 3905* Unix version only: To reduce the startup time, try to use mmap() instead 3906 of read() for the startup file. 3907 3908* Added a readline manual page. 3909 3910* Miscellaneous documentation updates. 3911 3912 39132.11 (4 July 1994) 3914================== 3915 3916User visible changes 3917-------------------- 3918 3919* X3J13 votes <115> and <114> are implemented: an elaborate LOOP macro. 3920 New macro LOOP-FINISH. 3921 Warning: The scoping rules for the iteration variables are hairy. If a 3922 FOR/AS initialisation form refers to an iteration variable of a subsequent 3923 FOR/AS clause, the effects are implementation dependent! 3924 3925* X3J13 vote <120> is implemented: New function MAP-INTO. 3926 3927* X3J13 vote <79> is implemented: New constants 3928 LEAST-POSITIVE-NORMALIZED-SHORT-FLOAT, 3929 LEAST-NEGATIVE-NORMALIZED-SHORT-FLOAT, 3930 LEAST-POSITIVE-NORMALIZED-SINGLE-FLOAT, 3931 LEAST-NEGATIVE-NORMALIZED-SINGLE-FLOAT, 3932 LEAST-POSITIVE-NORMALIZED-DOUBLE-FLOAT, 3933 LEAST-NEGATIVE-NORMALIZED-DOUBLE-FLOAT, 3934 LEAST-POSITIVE-NORMALIZED-LONG-FLOAT, 3935 LEAST-NEGATIVE-NORMALIZED-LONG-FLOAT. 3936 3937* The macro WITH-OUTPUT-TO-PRINTER now also works on DOS. 3938 3939* Fixed a bug in DO-SYMBOLS: A symbol which is exported from a used package 3940 was considered accessible in the using package even if it was shadowed by 3941 another present symbol of the same name. 3942 3943* Fixed a bug in the debugger which caused the BACKTRACE commands to print 3944 garbage if the current user interface language was not English. 3945 3946Other modifications 3947------------------- 3948 3949* Miscellaneous documentation updates. 3950 3951 39522.10 (22 June 1994) 3953=================== 3954 3955User visible changes 3956-------------------- 3957 3958* French support is now complete. Thanks to Jörg Höhle. 3959 3960* The user interface language (English, German or French) can now be chosen 3961 at startup time through a command line option. The constant *LANGUAGE* has 3962 been removed, and its value has been removed from *FEATURES*. New macros 3963 ENGLISH, DEUTSCH, FRANCAIS and LANGUAGE-CASE. 3964 3965* There is a command line option that makes CLISP behave more like what 3966 ILISP (a popular Emacs LISP interface) expects. 3967 3968* The function CLOS:CALL-NEXT-METHOD can now be called with arguments, but 3969 the check that the set of applicable methods must be the same as for the 3970 original arguments will be bypassed. 3971 3972* New functions READ-CHAR-SEQUENCE, WRITE-CHAR-SEQUENCE, READ-BYTE-SEQUENCE, 3973 WRITE-BYTE-SEQUENCE which perform fast block I/O. 3974 3975* Errors of type FLOATING-POINT-UNDERFLOW are inhibited in floating point 3976 computations (and zero is returned instead) during execution of the new 3977 macro WITHOUT-FLOATING-POINT-UNDERFLOW. 3978 3979* X3J13 vote <95> is implemented: If the readtable argument passed to 3980 GET-MACRO-CHARACTER and GET-DISPATCH-MACRO-CHARACTER is NIL, the standard 3981 readtable is used. 3982 3983* PROBE-FILE does not report an error any more if an intermediate directory 3984 in the path does not exist. NIL is returned instead. 3985 3986* The DEFCONSTANT warning about redefinition of a constant is inhibited if 3987 the constant's new and old values are the same (in the sense of EQL). 3988 Thanks to Marcus Daniels. 3989 3990* The function INTERACTIVE-STREAM-P knows that if the terminal stream is 3991 referring to a regular file (via input redirection) it is not interactive. 3992 3993* There is a user programmable kind of streams, called generic streams. 3994 New functions MAKE-GENERIC-STREAM, GENERIC-STREAM-CONTROLLER, 3995 GENERIC-STREAM-P, GENERIC-STREAM-READ-CHAR, GENERIC-STREAM-READ-BYTE, 3996 GENERIC-STREAM-LISTEN, GENERIC-STREAM-WRITE-CHAR, GENERIC-STREAM-WRITE-BYTE, 3997 GENERIC-STREAM-WRITE-STRING, GENERIC-STREAM-CLEAR-INPUT, 3998 GENERIC-STREAM-CLEAR-OUTPUT, GENERIC-STREAM-FINISH-OUTPUT, 3999 GENERIC-STREAM-FORCE-OUTPUT, GENERIC-STREAM-CLOSE. 4000 See <http://clisp.org/impnotes/gstream.html> for details. 4001 Thanks to Marcus Daniels and Don Cohen. 4002 4003* The macro WITH-OUTPUT-TO-PRINTER may now also work on OS/2. 4004 4005* Fixed a CLOS bug: Generic functions with both optional and keyword 4006 arguments did not work. 4007 4008* Fixed a serious bug in the compiler which caused incorrect code to be 4009 generated for functions like (LAMBDA (X) (SETQ X 1)). 4010 4011* Fixed a serious bug in the compiler which caused the compiler to crash 4012 when compiling functions which contain two or more calls to ASSERT. 4013 4014* Fixed a bug: The macroexpander of MULTIPLE-VALUE-SETQ built up a 4015 syntactically illegal form. 4016 4017* Fixed a bug in the reader: When reading pathnames from the syntax 4018 #S(PATHNAME ...), #n# references in pathname components were not 4019 resolved prior to calling MAKE-PATHNAME. 4020 4021* Fixed a bug in the reader: (read-from-string "1/") signalled an error 4022 of type DIVISION-BY-ZERO. 4023 4024* Fixed a bug in the terminal stream: If several consecutive READ-LINE 4025 operations on the terminal stream were performed without any text 4026 containing newlines being output between them, the prompt finally got 4027 duplicated and then became longer and longer. 4028 4029* Fixed a bug in the readline library (bad handling of prompts longer than 4030 one line). Thanks to Marcus Daniels. 4031 4032Installation 4033------------ 4034 4035* All non-Unix versions: Setting the local time zone should now be much 4036 easier. 122 time zone names are supported. 4037 4038Portability 4039----------- 4040 4041* Unix version only: Getting the time zone should be more robust. 4042 4043* Added support for NeXT (68k or i386 CPU) running NeXTstep 3.2. 4044 Thanks to Marcus Daniels. 4045 4046* Added support for Sequent PTX. Thanks to Marcus Daniels. 4047 4048* Added support for m88000 running DG/UX. Thanks to Pat McClanahan. 4049 4050* Added support for UnixWare. Thanks to Alexander Adam. 4051 4052* Added support for BSDI/386. Thanks to Atsuo Ohki. 4053 4054* More support for WATCOM C on DOS. Thanks to Blake McBride. 4055 4056* More support for IRIX 5. Thanks to Bjorn Remseth. 4057 4058* More support for Sun4m. Thanks to Neil Faulks. 4059 4060* Better support (speedup) for HP 9000/800 running HP-UX. 4061 4062* On HP 9000/700 running HP-UX: Do not depend directly on the assembler. 4063 4064* Maybe some support for SCO. Thanks to Cathy Bareiss. 4065 4066Other modifications 4067------------------- 4068 4069* Speedup SUBLIS and NSUBLIS. 4070 4071* Let all known versions of gcc2 emit dbra instructions for loops. 4072 Thanks to Jörg Höhle. 4073 4074* Renamed condition.lsp to conditio.lsp. 4075 4076* Miscellaneous documentation updates. 4077 4078 40798 January 1994 4080============== 4081 4082Portability 4083----------- 4084 4085* Remove (incomplete) support for VMS. 4086 4087 40887 January 1994 4089============== 4090 4091CLISP now compiles and runs on 4092* microcomputers: 4093 * Atari ST/TT 4094 * Amiga 500-4000 4095 * DOS 4096 * MS Windows 3.1 4097 * OS/2 2.0 4098* Unix workstations: 4099 * PC, Linux 4100 * PC, USL SVR4 4101 * Sun4, SunOS 4 or 5 4102 * HP9000/800, HP-UX 4103 * SGI Mips, Irix 4 or 5 4104 * DEC Alpha AXP, OSF 1.3 4105 * DECstation 5000, Ultrix 4.2 4106 * IBM RS/6000, AIX 3.2 4107 * M88000 4108 * Sun386, SunOS 4 4109 * Sun3, SunOS 4 (?) 4110 * HP9000/300, HP-UX or NetBSD 4111 * Apple MacII, A/UX (?) 4112 * Amiga 3000, Amiga Unix 2.1 4113 * NeXT, NeXTstep 3.1 4114 * PC, 386BSD or NetBSD 4115 * PC, Coherent 4.0 4116 * Atari ST/TT, MiNT 4117 4118 41192.9 (7 January 1994) 4120==================== 4121 4122Important note 4123-------------- 4124 4125* Changed bytecode format. All .fas files generated by previous CLISP versions 4126 are invalid and must be recompiled. 4127 4128User visible changes 4129-------------------- 4130 4131* X3J13 votes <186> and <31> are implemented: the Common Lisp Condition System. 4132 New macros 4133 DEFINE-CONDITION, IGNORE-ERRORS, HANDLER-CASE, HANDLER-BIND, 4134 RESTART-CASE, WITH-RESTARTS, WITH-SIMPLE-RESTART, RESTART-BIND, 4135 WITH-CONDITION-RESTARTS, 4136 new types 4137 RESTART, CONDITION, SERIOUS-CONDITION, ERROR, PROGRAM-ERROR, CONTROL-ERROR, 4138 ARITHMETIC-ERROR, DIVISION-BY-ZERO, FLOATING-POINT-OVERFLOW, 4139 FLOATING-POINT-UNDERFLOW, CELL-ERROR, UNBOUND-VARIABLE, UNDEFINED-FUNCTION, 4140 TYPE-ERROR, PACKAGE-ERROR, STREAM-ERROR, END-OF-FILE, FILE-ERROR, 4141 STORAGE-CONDITION, WARNING, 4142 SIMPLE-CONDITION, SIMPLE-ERROR, SIMPLE-TYPE-ERROR, SIMPLE-WARNING, 4143 new functions 4144 MAKE-CONDITION, SIGNAL, COMPUTE-RESTARTS, FIND-RESTART, INVOKE-RESTART, 4145 INVOKE-RESTART-INTERACTIVELY, ABORT, CONTINUE, MUFFLE-WARNING, STORE-VALUE, 4146 USE-VALUE, INVOKE-DEBUGGER, RESTART-NAME, 4147 ARITHMETIC-ERROR-OPERATION, ARITHMETIC-ERROR-OPERANDS, CELL-ERROR-NAME, 4148 TYPE-ERROR-DATUM, TYPE-ERROR-EXPECTED-TYPE, PACKAGE-ERROR-PACKAGE, 4149 STREAM-ERROR-STREAM, FILE-ERROR-PATHNAME, SIMPLE-CONDITION-FORMAT-STRING, 4150 SIMPLE-CONDITION-FORMAT-ARGUMENTS, 4151 new variables 4152 *BREAK-ON-SIGNALS*, *DEBUGGER-HOOK*. 4153 See <http://clisp.org/impnotes/conditions.html> for details. 4154 Thanks to David Gadbois who wrote most of this. 4155 4156* X3J13 vote <40> is partially implemented: New variable *PRINT-READABLY*. 4157 4158* X3J13 vote <34> is implemented: Arrays and packages may now appear as 4159 constants in compiled code. 4160 4161* X3J13 vote <90> is implemented: FUNCTIONP on symbols and conses now always 4162 returns NIL. The type FUNCTION is disjoint from SYMBOL and CONS. 4163 (COERCE object 'FUNCTION) is implemented. 4164 Warning: Old style calls like 4165 (FUNCTIONP object) 4166 may need to be converted to 4167 (OR (FUNCTIONP object) 4168 (SYMBOLP object) 4169 (AND (CONSP object) (EQ (CAR object) 'LAMBDA)) 4170 ) 4171 This fixes a CLOS bug: (TYPEP object 'FUNCTION) was not equivalent to 4172 (TYPEP object (FIND-CLASS 'FUNCTION)). 4173 4174* Two new debugger commands Break+ and Break- permit to set resp. remove 4175 breakpoints at specified EVAL or APPLY frames. 4176 4177* Warnings and errors produced by COMPILE-FILE are now accompanied by 4178 source line number information. 4179 4180* The sub-char passed as second argument to read dispatch macros is now 4181 exactly the first non-digit read from the stream. Previously it was its 4182 upper-case equivalent. 4183 4184* DEFPACKAGE now accepts an option (:DOCUMENTATION docstring). 4185 4186* DIRECTORY now accepts a keyword argument :CIRCLE. If it is non-NIL, 4187 the directory search for ".../" and "**/" wildcards on Unix avoids endless 4188 loops that may result from symbolic links. 4189 4190* The variable *LOAD-PATHS* in the Unix versions of config.lsp now uses 4191 "~/" (the home directory at run time) instead of #"~/" (the home directory 4192 at installation time). Thanks to Gabor Herr. 4193 4194* Unix and OS/2 versions: New dangerous functions MAKE-PIPE-IO-STREAM, 4195 RUN-SHELL-COMMAND and RUN-PROGRAM. 4196 4197* Unix version only: 4198 The command shell used by MAKE-PIPE-...-STREAM is now always /bin/sh; the 4199 environment variable SHELL is only used as interactive shell. 4200 Fixed a race condition in the functions EXECUTE, MAKE-PIPE-INPUT-STREAM, 4201 MAKE-PIPE-OUTPUT-STREAM that caused the child process to fail mysteriously. 4202 4203* Attacks such as (DO-ALL-SYMBOLS (S) (UNLESS (CONSTANTP S) (SET S NIL))) 4204 no longer crash CLISP. 4205 4206* Fixed a CLOS bug: DEFCLASS failed to signal an error if several direct slots 4207 had identical names. 4208 4209* Fixed a bug in the reader: When reading hash tables which contain #n# 4210 references, the hash codes must be recomputed after resolving the 4211 references. Thanks to Marcus Daniels. 4212 4213* Fixed a bug in the printer: Printed representations with two different 4214 #1= definitions could result when PRINT-OBJECT methods were called while 4215 *PRINT-CIRCLE* was true. Thanks to Marcus Daniels. 4216 4217Portability 4218----------- 4219 4220* Fixed five bugs in the number crunching routines that appeared on 4221 64-bit processors or in combination with the WIDE tagging scheme. 4222 4223* More support for 64-bit processors like DEC Alpha. 4224 4225* Added support for NeXT running NeXTstep 3.1. Thanks to Marcus Daniels. 4226 4227* Added support for Amiga 3000 running AMIX Unix. Thanks to Michel Loi. 4228 4229* Fixed a problem with Ctrl-C on HP-UX. Thanks to Gabor Herr. 4230 4231* Added support for HP9000/300 running HP-UX.

Thanks to Scott Kolodzieski. 4287 4288* Support for SunOS4 cc now works. 4289 4290* The makefile now also works with "parallel" make utilities (e.g. GNU make 4291 with option -j). Thanks to Rick Sladkey. 4292 4293* Easier porting: The most dangerous optimizations (inline asm() statements, 4294 global register allocations, ...) are inhibited if CLISP is compiled with 4295 option SAFETY=3. 4296 4297* Some modifications for the sake of gcc-2.5. 4298 4299Other modifications 4300------------------- 4301 4302* Speed up generic function dispatch. 4303 4304* Some kinds of objects take less space (all CPUs except 680x0). 4305 4306* The list of X3J13 votes and their current status in CLISP has been moved 4307 from file `src/defs2.lsp' to file `src/cltl2.txt'. 4308 4309* The code for setting up a connection to an X server (file `src/socket.d') 4310 has been completely rewritten. 4311 4312* Miscellaneous documentation updates. 4313 4314 43152.7 (27 September 1993) 4316======================= 4317 4318User visible changes 4319-------------------- 4320 4321* COMPILE-FILE now handles top-level forms as described in CLtL2 p. 90: 4322 The macroexpansion of a top-level form is considered a top-level form. 4323 When a top-level form is a PROGN, LOCALLY, COMPILER-LET, SYMBOL-MACROLET 4324 or MACROLET form, the subforms of its body are considered top-level forms 4325 too and are compiled separately. 4326 This allows things like 4327 (PROGN (DEFCONSTANT X 3141) (DEFUN GET-X () X)) 4328 or 4329 (PROGN (DEFCLASS SHIP () ()) (DEFUN SHIP-P (X) (TYPEP X 'SHIP))) 4330 to work. 4331 Warning: If you want to inhibit this splitting into separate forms (for 4332 example, because several of the forms refer to the same uninterned symbol), 4333 you have to use (LET () (PROGN ...)) instead of (PROGN ...). 4334 4335* X3J13 vote <144> is implemented: New macro DECLAIM. 4336 4337* X3J13 vote <113> is implemented: The macro LOCALLY is now a special form. 4338 4339* Fixed a serious bug in the compiler: When compiling functions inline 4340 whose parameters are special variables, incorrect code could be generated. 4341 4342* Fixed a bug in the compiler which caused the compiler to crash in some 4343 rare cases, notably when compiling Garnet-2.2. 4344 4345* Fixed a bug that prevented the debugger commands DOWN and BOTTOM from 4346 working on Linux and SunOS. 4347 4348* Fixed a CLOS bug: Specifying &KEY without &REST in generic function 4349 lambda lists did not have the desired effect. 4350 4351* DEFCLASS supports both :DEFAULT-INITARGS syntaxes. 4352 4353* DEFGENERIC is more tolerant about invalid declarations. 4354 4355Portability 4356----------- 4357 4358* Added Dynix/ptx Sequent support. Thanks to Esther Davis. 4359 4360* Added support for RS/6000 CPU and AIX. Thanks to Gabor Herr. 4361 4362Other modifications 4363------------------- 4364 4365* Made the memory allocation and (ROOM), (TIME ...) more virtual memory 4366 efficient (less paging on Unix and DOS). Thanks to Don Cohen. 4367 4368* Added Geoffrey Gordon's "LISP tutorial". 4369 4370* Renamed stdwin.lsp to stdwin2.lsp. 4371 4372* Miscellaneous documentation updates. 4373 4374 43752.6.1 (1 September 1993) 4376======================== 4377 4378Important note 4379-------------- 4380 4381* Changed bytecode format. All .fas files generated by previous CLISP versions 4382 are invalid and must be recompiled. 4383 4384User visible changes 4385-------------------- 4386 4387* Unix version only: The command line option -M now also accepts memory images 4388 that were compressed using GNU gzip. 4389 4390* Fixed a CLOS bug: MAKE-INSTANCE now behaves as if it were calling 4391 INITIALIZE-INSTANCE, and INITIALIZE-INSTANCE and REINITIALIZE-INSTANCE 4392 behave as if they were calling SHARED-INITIALIZE. 4393 4394* Fixed a CLOS bug: NO-APPLICABLE-METHOD failed to be called in some cases 4395 when no method was applicable. 4396 4397* Relating to X3J13 vote <89>: The first argument to the functions FUNCALL and 4398 APPLY, denoting a function, may now also be a list (SETF symbol). 4399 4400* Fixed a bogus error message that occurred when storing an out-of-range 4401 integer into an array of element-type (UNSIGNED-BYTE 32). 4402 4403Portability 4404----------- 4405 4406* Added NetBSD support. Thanks to Charles Hannum. 4407 4408Other modifications 4409------------------- 4410 4411* Added Jeff Dalton's "brief CLOS guide". 4412 4413* Miscellaneous documentation updates. 4414 4415 44162.6 (22 August 1993) 4417==================== 4418 4419Important note 4420-------------- 4421 4422* Changed bytecode format.

New package CLOS 4429 containing the macros 4430 DEFCLASS, DEFMETHOD, DEFGENERIC, GENERIC-FUNCTION, GENERIC-FLET, 4431 GENERIC-LABELS, WITH-SLOTS, WITH-ACCESSORS, 4432 the functions 4433 FIND-CLASS, (SETF FIND-CLASS), CLASS-OF, CLASS-NAME, (SETF CLASS-NAME), 4434 SLOT-VALUE, SLOT-BOUNDP, SLOT-MAKUNBOUND, SLOT-EXISTS-P, 4435 CALL-NEXT-METHOD, NEXT-METHOD-P, 4436 NO-APPLICABLE-METHOD, NO-PRIMARY-METHOD, NO-NEXT-METHOD, 4437 FIND-METHOD, ADD-METHOD, REMOVE-METHOD, COMPUTE-APPLICABLE-METHODS, 4438 METHOD-QUALIFIERS, FUNCTION-KEYWORDS, SLOT-MISSING, SLOT-UNBOUND, 4439 PRINT-OBJECT, DESCRIBE-OBJECT, MAKE-INSTANCE, INITIALIZE-INSTANCE, 4440 REINITIALIZE-INSTANCE, SHARED-INITIALIZE, 4441 the classes 4442 STANDARD-CLASS, STRUCTURE-CLASS, BUILT-IN-CLASS, STANDARD-OBJECT, 4443 STANDARD-GENERIC-FUNCTION, STANDARD-METHOD and all predefined classes, 4444 and the method combination 4445 STANDARD. 4446 See <http://clisp.org/impnotes/classes.html> for details. 4447 X3J13 vote <13> is implemented, too. 4448 4449* X3J13 vote <63> is implemented: DESCRIBE receives the output stream as 4450 optional argument. New function CLOS:DESCRIBE-OBJECT. 4451 4452* X3J13 vote <149> is implemented: The second argument to SUBSEQ may now 4453 be NIL. Thanks to Thomas Kirk. 4454 4455* X3J13 vote <175> is implemented: TAILP now also works on dotted lists. 4456 4457* X3J13 vote <124> is implemented: (DECLARE (OPTIMIZE (DEBUG ...))) is legal. 4458 4459* The type specifier (EQL object), a synonym for (MEMBER object), is now 4460 implemented. 4461 4462* New DEFSTRUCT option :INHERIT which is exactly like :INCLUDE except that it 4463 does not create new accessors for the inherited slots. Use this option to 4464 avoid the problems that occur when using the same :CONC-NAME for the new 4465 and the inherited structure. 4466 4467* Fixed EXPORT and USE-PACKAGE: Do not signal a name conflict between the 4468 symbol being exported and a symbol accessible in the using package if 4469 the latter symbol is on the list of shadowing symbols of the using package. 4470 4471* Fixed VECTOR-PUSH-EXTEND. It now works on vectors of dimension 0 and 4472 on bit-vectors. 4473 4474* Fixed PRINT-UNREADABLE-OBJECT: Do not output adjacent spaces. 4475 4476* Fixed a bug in the reader that caused an endless loop or endless recursion 4477 when resolving #n=/#n# references in objects that already contained cyclic 4478 data structures, e.g. when reading (#1=a #.'#2=(b . #2#) #1#). 4479 4480* Fixed a bogus error message in the complex number reader. 4481 4482Portability 4483----------- 4484 4485* The DOS README explains how to run CLISP in the DOS box of Microsoft 4486 Windows. Thanks to Ralf Muschall. 4487 4488* Added Sinix support. Thanks to Manfred Weichel. 4489 4490* Improved installation on OS/2. 4491 4492Other modifications 4493------------------- 4494 4495* A function proclaimed INLINE will be taken inline in a wider set of 4496 circumstances. (Previously INLINE worked only when that function was being 4497 used in the same file or in a file that REQUIREd the file defining the 4498 function.) 4499 4500* The compiler now produces better code for (APPLY (FUNCTION fun) args). 4501 4502* Changed the default memory size from 2 megabytes to 2.5 megabytes. 4503 4504* Miscellaneous documentation updates. 4505 4506 45072.5.1 (17 July 1993) 4508==================== 4509 4510User visible changes 4511-------------------- 4512 4513* X3J13 vote <150> is mostly implemented: Reading and printing of symbols 4514 (and characters with bits or fonts attributes) is now affected by 4515 (READTABLE-CASE *READTABLE*), whose value may be one of :UPCASE, :DOWNCASE 4516 and :PRESERVE. New place READTABLE-CASE. 4517 4518* Support for immutable objects is implemented. Attempts to modify read-only 4519 data will signal an error. Program text and quoted constants loaded from 4520 files are considered read-only data. Never again will you be allowed to 4521 write programs that destructively modify themselves! 4522 This works only for Unix implementations with powerful virtual memory 4523 management, currently only Linux and SunOS. To enable it, you have to 4524 add -DIMMUTABLE to the CFLAGS in the makefile when building CLISP. 4525 4526* Fixed DEFUN such that 4527 (progn 4528 (flet ((bar (x) (+ x 10))) (defun bar (y) (if (zerop y) 1 (bar (1- y)))) 4529 (bar 1) 4530 ) 4531 returns 10 instead of 1. 4532 4533* Fixed a bug in the compiler that caused the compiler to crash by endless 4534 recursion and stack overflow when compiling assignments to symbol macros. 4535 4536Portability 4537----------- 4538 4539* Added support for m88000 CPU. 4540 4541* Amiga version: detect 68000 CPU, for better use of present memory. 4542 4543Other modifications 4544------------------- 4545 4546* Miscellaneous documentation updates. 4547 4548 45492.5 (29 June 1993) 4550================== 4551 4552User visible changes 4553-------------------- 4554 4555* X3J13 vote <89> is implemented: (SETF symbol) is now a valid syntax for a 4556 function name in (funname ...), (FUNCTION funname), (DEFUN funname ...), 4557 (COMPILE funname ...), (DISASSEMBLE funname), (ED funname), FLET, LABELS etc. 4558 New function FDEFINITION. 4559 4560* X3J13 vote <173> is implemented: New special form SYMBOL-MACROLET. The 4561 macroexpansion environment passed to macro expanders and to MACROEXPAND-1, 4562 MACROEXPAND, GET-SETF-METHOD, GET-SETF-METHOD-MULTIPLE-VALUE now comprises 4563 both the variable environment and the function environment. 4564 New macro DEFINE-SYMBOL-MACRO. 4565 4566* New macro PRINT-UNREADABLE-OBJECT. 4567 4568* Fixed a bug: The string comparison functions STRING<, STRING>, STRING<=, 4569 STRING>=, STRING/=, STRING-LESSP, STRING-GREATERP, STRING-NOT-GREATERP, 4570 STRING-NOT-LESSP, STRING-NOT-EQUAL now return the index of the first mismatch 4571 instead of T. 4572 4573* Fixed a bug: The functions REMOVE-DUPLICATES and DELETE-DUPLICATES produced 4574 an out-of-bounds error when called on a small sequence, with :FROM-END T 4575 argument and without :END argument. 4576 4577Portability 4578----------- 4579 4580* Updated support for DJGPP. 4581 4582Other modifications 4583------------------- 4584 4585* The macros SETF, PUSH, POP, PUSHNEW have been completely rewritten. 4586 4587* Changed internal representation of special form handlers: They now consume 4588 regular memory. This frees one type tag, which will be used by CLOS 4589 instances. 4590 4591* Miscellaneous documentation updates. 4592 4593 45942.4 (24 May 1993) 4595================= 4596 4597User visible changes 4598-------------------- 4599 4600* New macro DEFPACKAGE. 4601 4602* New function FUNCTION-LAMBDA-EXPRESSION. 4603 4604* New package SCREEN containing some functions for random screen access 4605 (Unix, DOS, OS/2, Atari, VMS versions only). 4606 4607* X3J13 vote <5> is implemented: The value of *APPLYHOOK* must now be 4608 a function of two arguments. 4609 4610* X3J13 vote <104> is implemented: COMPILE-FILE now binds *READTABLE*. 4611 4612* X3J13 vote <161> is implemented: SHADOW now accepts strings as well 4613 as symbols. 4614 4615* Fixed a bug in the compiler which caused the compiler to crash when 4616 compiling (CASE key ...) forms with constant key. 4617 4618* Fixed a bug in the compiler which produced unloadable .fas files 4619 when compiling forms like (SETF ... (FUNCTION LIST)). 4620 4621* Fixed a bogus error message in the AREF function. 4622 4623* The built-in editor on Unix now handles the Delete key the same way 4624 as the Backspace key or Ctrl-H. 4625 4626* Fixed a bug in + that occasionally caused (- x x) to return a 4627 long-float zero which was not EQL to the other zeroes of type LONG-FLOAT. 4628 4629* Fixed a bug: Correctly do round-to-even when adding two long-floats. 4630 4631* Fixed a bug: The destructive sequence functions DELETE etc. failed to 4632 produce an error when called on a sequence of type LIST and with an :END 4633 argument larger than the list's length. 4634 4635* Corrected the branch cuts of the complex ATAN and ATANH functions. 4636 4637Portability 4638----------- 4639 4640* 68000 and other versions: Fixed a bug in the low-level division algorithm. 4641 4642* Mips and Vax versions: Finished the low-level number crunching routines. 4643 4644* Added Ultrix support. 4645 4646* Added Coherent support. 4647 4648* Finished Sun3 support. 4649 4650Other modifications 4651------------------- 4652 4653* The file `src/defs2.lsp' contains a list of X3J13 votes and their current 4654 status in CLISP. 4655 4656* The file `src/foreign.txt' documents how to do function calls to foreign 4657 language routines from within CLISP. 4658 4659* Miscellaneous documentation updates. 4660 4661 46622.3.1 (5 April 1993) 4663==================== 4664 4665Portability 4666----------- 4667 4668* 68000/68020 versions: Fixed some bugs in the low-level number crunching 4669 routines. 4670 4671* Improved efficiency of the WIDE tagging scheme. 4672 4673 46742.3 (30 March 1993) 4675=================== 4676 4677User visible changes 4678-------------------- 4679 4680* Fixed a bug in + that caused the sign of (+ x y) to be wrong when x and y 4681 were double-floats satisfying 0 < x < -y or 0 > x > -y . 4682 4683* New special form LOAD-TIME-VALUE. 4684 4685* The function DIR now sorts its output. 4686 4687* A new place (DEFAULT-DIRECTORY) manages the "current directory". 4688 4689* When LOAD is called with a pathname as argument that contains a parent 4690 directory component (".."): Ignore the variable *LOAD-PATHS*, avoid an error. 4691 4692* Fixed TRACE so that functions calling TRACE are correctly handled by 4693 COMPILE-FILE. 4694 4695Portability 4696----------- 4697 4698* Unix version: Correct handling of system calls that are interrupted 4699 by signals. 4700 4701* Finished IRIX support. 4702 4703Other modifications 4704------------------- 4705 4706* Miscellaneous documentation updates. 4707 4708 47092.2.2 (19 March 1993) 4710===================== 4711 4712User visible changes 4713-------------------- 4714 4715* Replaced variable *TEMPFILE* by a function EDITOR-TEMPFILE. 4716 4717Portability 4718----------- 4719 4720* Unix version: Corrected detection of ANSI C header files. 4721 4722* Unix version: Check whether signal handlers are automatically reinstalled 4723 when activated. 4724 4725* Made readline library ANSI C compliant and (on Unix) auto-configuring. 4726 4727* In case there is no room for three extra bits in a symbol pointer, 4728 allocate three stack words per binding in a VAR frame (instead of two stack 4729 words). This completes the Amiga 3000/4000 version. 4730 4731* Completed memory model SPVW_PURE_BLOCKS: There is a large contiguous memory 4732 area for each kind of Lisp object. This model is used only if memory can 4733 be allocated at prescribed addresses, for example on Unix with mmap(). 4734 4735* More 386BSD support. 4736 4737Other modifications 4738------------------- 4739 4740* Remove limit on the number of files that may be specified on the command 4741 line.
