   39: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
   40: - major bug is fixed in STD format (1E7 sq prints 1);
   41: - major bug is fixed in READ intrinsic (socket). This bug was introduced
   42: by a new feature in glibc.
   43: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
   44: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
   45: "ALL" IMPLICIT when it runs in interactive mode;
   46: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
   47: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
   48: to use SAVE to manipulate global variables;
   49: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
   50: subroutines;
   51: - fix major memory access violation in evaluation subroutine. Only occurs
   52: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
   53: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
   54: when X was a vector or a table.
   55: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)
   56: - Gnuplot is upgraded;
   57: - flag 34 is now used to enable or disable control character evaluation;

   62: - FLOW socket support is added;
   63: - FLOW sequential files are added;
   64: - new escape sequence is added to handle flow files (\x + hexadecimal code).
   65: Known escape sequences are \", \b, \n, \t, \x?? and \\.
   66: * Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
   67: - Ncurses is upgraded to 5.8;
   68: - ALARM is fixed by filling isdst field;
   69: - catch ECONNRESET in write intrinsic to return an execution error instead of
   70: system one;
   71: - fix a typo in HELP intrinsic;
   72: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;
   73: - Lapack is upgraded to 3.3.0;
   74: - libmtmalloc is now default Solaris allocator;
   75: - ncurses is upgraded;
   76: - regression introduced by 4.0.19 is fixed in signal management.
   77: Interruption1() could be called from itself and raises bus error (on sparc) or
   78: segmentation fault;
   79: - sqlite is upgraded to 3.7.4;
   80: - OpenSSL is upgraded to 1.0.0c;
   81: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);

   83: - gnuplot is upgraded to 4.4.2 due to major bugs.
   84: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
   85: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
   86: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
   87: corruption. As internal memory management have been improved, a best fit
   88: allocator like ptmalloc3 is not required anymore;
   89: - gnuplot is upgraded to 4.4.1;
   90: - deadlock is fixed in signal handlers: same mutex was used in standard
   91: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
   92: and signal handlers. A new signal handler specific mutex is added;
   93: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
   94: that has to be evaluated by ->NUM;
   95: - rplfile build process is modify to be sure that rplfile is not modified
   96: after rpl build stage (to be sure that rplfile checksum is not modified after
   97: rpl compilation);
   98: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
   99: modified to remove yacc code and renamed;
  100: - some workarounds have been written to not use buggy klibc SystemV IPCS.
  101: ABORT now works on eComStation;
  102: - sqlite is upgraded to 3.7.2;
  103: - bug is fixed in software interrupts. When both process have different PID,
  104: parent process was not interrupted if it is not group master process. To fix
  105: this bug, SIGINJECT signal is not sent by child process but by control thread
  106: in parent process;
  107: - minor bug is fixed in data injection (POKE) that does not work as expected
  108: when child process is protected by NRPROC.
  109: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
  110: - --enable-sysv-sems is added to configure script to use SystemV semaphores
  111: functions instead of POSIX functions. This function is disabled or forced on
  112: systems that does not provide correct POSIX or SysV semaphores subsystem;
  113: - a dirty but not quick patch is written to workaround broken siginfo
  114: structures. This patch has been successfully tested. It uses a segment of
  115: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
  116: (Unix PID);
  117: - some OpenBSD's hacks are added;
  118: - broken siginfo->si_pid field is now checked by configure script;
  119: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
  120: - random generator is cloned by SPAWN;
  121: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
  122: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
  123: or freeaddrinfo;
  124: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
  125: - major bug is fixed in CHR intrinsic when obtained character is not printable;
  126: - Lapack is upgraded to 3.2.2;
  127: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
  128: - TOKENIZE is now able to convert escape sequences;
  129: - ATPOKE and CLRATPOKE new intrinsics are added;
  130: - --enable-full-static configure flag is added. With this flag, mysql and
  131: postgresql libraries are statically linked in rpl executable;
  132: - units Makefile is modified to avoid readline and ncurses usages;
  133: - sqlite is upgraded to 3.7.0.1;
  134: - units is upgraded to 1.88;
  135: - another major bug is fixed in the same variable creation subroutine.
  136: Level 0 and 1 variables adresses were swapped when a global variable masked
  137: a name of RPL/2 routine;
  138: - major bug is fixed in global variable creation subroutine. When a global
  139: variable was created and when a local variable existed with the same name,
  140: computed address of global variable was wrong;
  141: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
  142: is forced in front of all libraries.
  143: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
  144: - BACKTRACE intrinsic is added;
  145: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
  146: when this structure is included in IFERR/THEN/END structure and when an error is
  147: caught;
  148: - major bug is fixed in analyse() subroutine. When evaluation() returned error
  149: in a compiled program, analyse() caught this error twice and randomly aborted
  150: with a segmentation error;
  151: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
  152: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
  153: signals;
  154: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
  155: matrix.
  156: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
  157: - minor bug is fixed in evaluation() subroutine. With this patch, same program
  158: returns same result with or without -p flag;

  160: - openssl is upgraded to 1.0.0a;
  161: - interrupt stacks are now FIFO instead of LIFO;
  162: - debug memory allocation subroutines are improved to run in multithreaded
  163: programs;
  164: - some memory leaks are fixed in process management (SPAWN and DETACH);
  165: - version verification is added to shared objects;
  166: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
  167: linux (false mremap() prototype);
  168: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
  169: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
  170: - all '-' are replaced by '_' in random generator list;
  171: - minor memory leak is fixed in OPEN intrinsic (socket);
  172: - major bug is fixed in IFERR structure. Only occurs in compiled program;
  173: - major bug is fixed in copie_objet() and liberation(). Only concerns
  174: format in FCH (file descriptor) and SCK (socket descriptor);
  175: - debug routines are improved;
  176: - PROCID is added;
  177: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
  178: and to not use swap;
  179: - major bug is fixed in sql support. SQL connections were closed in all chield
  180: process;
  181: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
  182: discovered in Solaris thread safe allocators (libmalloc and libumem) that
  183: are first fit class allocators. Solaris libmtmalloc works better and is
  184: a best fit class allocator but its performance is poor than ptmalloc3
  185: performance;
  186: - major bug is fixed in ROW+ intrinsic (new row was not added where it
  187: should);
  188: - minor bugs are fixed in interruptions.c (semaphores values when error is
  189: caught);
  190: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
  191: created by SPAWN;
  192: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
  193: ATEXIT. If it receives SIGFABORT, it does not;
  194: - ONEXIT is renamed in ATEXIT;
  195: - ONEXIT new intrinsic is added.
  196: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
  197: - major bug is fixed in static and shared variables initialization subroutine.
  198: This bug only occurs when RPL/2 tries to create a shared or static variable
  199: from an expression;
  200: - major bug is fixed in copie_etat_processus(). A field that contains
  201: information about shared variable was not copied to new processus structure;
  202: - some little memory leaks are fixed in evaluation(), recherche_type() and
  203: sequenceur(). They only occured when syntax error were caught;
  204: - IMPLICIT causes execution error instead system error;
  205: - Hurd support is improved but currently broken because Hurd does not support
  206: SIG_INFO. Work in progress;
  207: - OpenBSD specific support is removed from sources;
  208: - support for Mac OS X and Windows/Cygwin is added.
  209: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)
  210: - implicit names can now be disabled by new IMPLICIT intrinsic:

  244: Makefiles;
  245: - -a command line option analyzes program (structure and syntax) and
  246: sends preprocessor output to standard output. This option is used by
  247: rplc (RPL/2 compiler).
  248: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
  249: - in formatted file, string format returned a variable length string even if
  250: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
  251: a variable length string and 'CHARACTER*(n)' a fixed length string;
  252: - keyed access files support is added. Currently, only formatted files are
  253: supported;
  254: - direct access files support is added. Currenlty, these files can only be used
  255: in formatted mode;
  256: - virtual variables are now writte in UTF-8 and all special characters
  257: in string are escaped;
  258: - all formatted files are now converted into UTF-8;
  259: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
  260: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
  261: each execution (md5 and sha1 sums) to enhance security. If one of these tools
  262: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
  263: on a non recoverable system error;
  264: - openssl and sqlite3 libraries are added;
  265: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
  266: variable indicates RPL/2 root directory. If it is not set, root path
  267: is given by configure script (d_exec_path);
  268: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
  269: - configure.in and makefile.am's are modified to add Cygwin support. Interix

  275: fraction intead real one;
  276: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
  277: - Makefile.am are modified to authorize parallel builds;
  278: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
  279: and writes warning to standard output;

  282: avoid a minor bug in EDIT and VISIT intrinsics;
  283: - minor bug is fixed in formateur_reel();
  284: - file-5.03 is patched to avoid bus error on systems that require memory
  285: alignment;
  286: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
  287: were able to be avoided by evaluation routine.
  288: * Tue Jan 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.9 (RPL/2)

  300: list argument and inexistant elements).
  301: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
  302: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
  303: signals sent to main process were not caught because DAEMON did not replace
  304: old pid by new one;
  305: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
  306: evaluation when an error is reported from a subroutine in another subroutine.
  307: For example, error was not caught in following program when it is executed with
  308: -p option :
  309:     TEST << iferr TEST2 then end >>
  310:     TEST2 << 0 inv >>
  311: - major bug is fixed in variable management. Some local variables were
  312: seen as global ones;
  313: - major bug is fixed in rplcore. Rplcore entered in dead lock when
  314: script file contains a multibyte character;
  315: - IN intrinsic is added;
  316: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
  317: returned false ;
  318: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
  319: programs;
  320: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;

  325: - major bug is fixed in -A command line option (NULL character is missing);
  326: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
  327: made by blocks (1024 bytes). When an incomplete multibyte sequence is
  328: encountered at end of block, subroutine aborts with an execution error;
  329: - major bug is fixed in OPEN (TCP/IPv4 sockets).
  330: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
  331: - DISP now locks stdout;
  332: - rpliconv is added to replace standard iconv provided by operating system.
  333: Indeed, conversion between different encodages requires transliteration
  334: that is not offered by some iconv utility;
  335: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
  336: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
  337: not be found), SYSEVAL enters in a dead lock;
  338: - fprintf is replaced by some functions that allow transliterations between
  339: locales;
  340: - '"' can now be used in strings ("\"");
  341: - iconv is called with -c in preprocessor stage. It is done to write
  342: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
  343: - double free is fixed in liberation() (type SQL, only occurs when locale is
  344: set);
  345: - LOCALIZATION, UCASE and LCASE are added;
  346: - major bug is fixed in EXIT intrinsic that was able to return a false
  347: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
  348: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
  349: used in onLoading from shared library, USE was pushed on stack as algebraic
  350: expression;
  351: - libiconv is upgraded to 1.13.1;
  352: - gnuplot is upgraded to 4.2.6;
  353: - gsl is upgraded to 1.13.

  355: - pipe() is overwritten by a macro to avoid a system error. Communication
  356: between process are done with pipes and these pipes are managed by a
  357: specific asynchrone thread. If a script try to create more threads than
  358: management thread can destroy, you can quickly achieve maximum number of
  359: opened files and pipe() shall return a system error. This macro tries to create
  360: pipes. If pipe() function returns an error, macro waits and retries. If
  361: number of retries is greater than a hardcoded value, macro returns an error;
  362: - major bug (deadlock) is fixed in process and thread management. I hope
  363: this bug shall be the last one;
  364: - major bug is fixed in DET intrinsic (determinant was computed without LU
  365: diagonalization);
  366: - SWAPCNTXT is added;
  367: - minor bug is fixed in Makefile.am (licences rule).
  368: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
  369: - some bugfixes are added in process management;
  370: - all process management is rewritten to avoid usage of defunct process
  371: or thread number;
  372: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
  373: was called before a pending interruption5 (SIGFSTOP), signal handler uses
  374: a freed semaphore and corrupts heap;
  375: - CLRERR is added to erase previous errors;
  376: - ERRN and ERRM return exception message and number;
  377: - major bug is fixed in interruptions.c. All signal are now bufferised
  378: when semaphore_liste_threads is null to avoid deadlock. This bug only
  379: occured when STOP was sent to a dying thread or process (when this thread or
  380: process was running retrait_thread());
  381: - matrix rank is computed before matrix inversion;
  382: - file locks are added to stdin and stdout. stderr is not locked because
  383: all messages written by signal handlers are sent to stderr;
  384: - configure.in script is modified to test gcc version and avoid a bug in
  385: gcc older than 4.4;
  386: - some benchmarks have been done :

  418: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
  419: can call twice CSTOP without RSTOP;
  420: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
  421: SMPHRTRYDECR, SMPHGETV).

  431: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
  432: process termination);
  433: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
  434: its parent);
  435: - a mutex to protect fork() syscall is added;
  436: - all mutexes are unlocked after fork() in DETACH;
  437: - minor bug (double free corruption) is fixed in CLOSE intrinsic;
  438: - major bug is fixed in lecture_pipe when a nullified list is sent into a pipe;

  446: - a memory leak is fixed in REMOVE intrinsic;
  447: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
  448: and due to a libmysqlclient that is not thread safe).

  458: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
  459: process is killed;
  460: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
  461: know typeof() intrinsic function. This function is not standard but exists
  462: under Sun Studio, gcc, and maybe some others compilers. If this function does
  463: not exist on your compiler, you can change its definition by old one in
  464: src/rpl.h;
  465: - fflush() can now be interrupted by signal (SunOS);
  466: - fflush(NULL) is called before all fork() occurrences;

  485: is send from an external process;
  486: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
  487: deadlock when a huge amount of threads is launched);
  488: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
  489: arguments types are unsupported;
  490: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

  505: static variable that is shared by multiple threads;
  506: - '->' intrinsic is improved. All object copies have been avoided;
  507: - -n flag is added to catch HUP signal. stderr and stdout are redirected
  508: to a file, stdin is redirected to /dev/null when control process is killed;
  509: - a mutex is added to each object (before this modification,
  510: RPL/2 used a global mutex and performances in multithreaded programs were very
  511: poor.);

  525: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
  526: that all programs that worked with old SQL intrinsic can now work with
  527: SQLQUERY. With all new programs, you can open a real connection to databases;
  528: - NRPROC is added. This new intrinsic is used to catch error from child
  529: process. Without NRPROC, any errors returned by child process cause
  530: main process to abort;
  531: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
  532: starts a new process). There are no mutexes in RPL/2 because all spawned process
  533: use specific context. Nevertheless, shared variables and associated mutexes
  534: should be added;
  535: - -D flag and DAEMONIZE intrinsic have been added;
  536: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

  551: it's done. Data integrity is now respected during transmission (POKE, SEND and
  552: SWI);
  553: - ITRACE is added. This intrinsic is only used to debug internal structures and
  554: should not be used in regular programs;
  555: - SWISTATUS is written;
  556: - WFACK is written;

  623: workaround for this major bug. Nevertheless, all others capabilities seems to
  624: work fine;
  625: - '->' is modified to return error when program tries to initialiaze two

  651: software interrupts;
  652: - HEAD, TAIL and REVLIST intrinsics are added;
  653: - function pointers have been added to function description;
  654: - new analyse() routine is written. All instrinsics are now in a N-tree;

  666: { "mysql:iso-8859-1" "server" "database" ... };
  667: - major bug is fixed un analyse_algebrique(). When DISP printed an algebraic
  668: object, 'DISP()' was pushed in stack;
  669: - same major bug is fixed in <, >, <=, >= and <>;
  670: - major bug fixed in formateur() (segfault when a symbol is used without "'");
  671: - major bug is fixed in DUPN intrinsic;

  678: without this option !
  679: - new garbage collector (and more efficient) is written;
  680: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
  681: not support real time signals, RPL/2 cannot use multitasking functions;
  682: - error returned by preprocessor are now catched by RPL/2;
  683: - -p option is added. With this option, all scripts are compiled before
  684: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
  685: 40% faster;
  686: - read and write operations in pipe() are rewritten to be sure that such
  687: operations are atomic;
  688: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

  715: greater than one second. On some systems, usleep argument must be lower
  716: than 1E6;
  717: - numeric and character formats are now tested;
  718: - -A flag is added. -A is used to give command line parameters to main
  719: routine. Example:

  805: - minor bug is fixed in recherche_type(). Don't forget that space
  806: are not significant in algebraic expression:
  807: '12 3+ 12    X' is the same expression than '123+12X';
  808: - src/Makefile.am is modified to avoid double compilation process;
  809: - --enable-final-run-path is added to configure.in script;

  827: functions were case unsensitive when they were evaluated from RPN expressions;
  828: - HELP function is rewritten to be more friendly (a la OpenVMS);
  829: - external wrapper (rplplot) is written to force usage of gnuplot provided
  830: by RPL/2 if it is built during build process. If this build does not exist,
  831: it tries to launch regular gnuplot;
  832: - gnuplot is added to source tree to avoid some trouble between preinstalled
  833: gnuplot and release used by RPL/2. This addition to source tree is
  834: required by some incompatibility between gnuplot releases;

  840: not writable;
  841: - major regression is fixed in SYSEVAL intrinsic due to introduction of
  842: error scrutation.

  884: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
  885: versions of PROTECT and UNPROTECT that only deal with global variables
  886: (see RCL/SAVE);
  887: - variable management routines have been rewritten. The new ones are
  888: uncompatible with the old ones. Before these changes, a local variable
  889: was exported to a child subroutine, but cannot be modified into this
  890: child subroutine. Now, a local variable is accessible only in its subroutine;
  891: - SAVE intrinsic is added to manipulate global variables;

 1212: fine...);
 1213: - NOT is not correctly formatted in formateur.c:
 1214: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
 1215: with a NOTZ function !
 1216: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

 1219: - RPL/2 is tested with efence and valgrind;
 1220: - configure.in script is modified;
 1221: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

 1282: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
 1283: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
 1284: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

 1301: - SCLS is added;
 1302: - DRWS now uses COLS to draw 2D graphics;
 1303: - PPAR and SPAR are written. SPAR returns a list that contains the
 1304: size of the statistical matrix (or "UNAVALAIBLE" if there is any
 1305: statistical variable, or "DISABLED" if its type is not one of the type of
 1306: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
 1307: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
 1308: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
 1309: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
 1310: disabled. Arguments of EXTERNAL are case sensitive because the external
 1311: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
 1312: of known external functions but add the new list to the last. { "all" }
 1313: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
 1314: external names of the known functions;
 1315: - mkrplso.in is modified.
 1316: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
 1317: - vim syntax file is upgraded;
 1318: - a minor mistake is fixed in recherche_instruction_suivante();

 1330: VISIT does not find a name in level 1;
 1331: - configure.in script is modified to add a new test (--enable-debug
 1332: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
 1333: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
 1334: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
 1335: 'MATRIX' { 2 2 3 } GETR;
 1336: - LOGSCALE intrinsic is improved and now, it can be used as
 1337: { "main" "auxiliary" X Y } LOGSCALE;
 1338: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
 1339: same than AXES:
 1340: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
 1341: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
 1342: { { -10 10 } "automatic" } SCALE.
 1343: Warning, it is not possible to ask a logarithmic scale with this intrinsic
 1344: because it changes only the dimension of the screen. To have a logarithmic
 1345: scale, you must use LOGSCALE intrinsic:
 1346: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
 1347: screen on second scale;
 1348: - { X X } autoscale and { Y Y } logscale are now invalid;
 1349: - *D is added (depth multiplication, for 3D graphics);
 1350: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
 1351: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
 1352: - a major bug is fixed in GETI instrinsic when it is used with a name
 1353: that contains a matrix or a vector (bad upper bounds conditions in
 1354: incrementation);
 1355: - DISP intrinsic now uses the 33-th flag. When it is not set
 1356: (default), a final carriage return is sent to the terminal;
 1357: - AXES intrinsic only takes a list that can contains the keywork
 1358: "main" or "auxiliary". Before this modification, this keyword was in
 1359: the first stack level;
 1360: - vim syntax file is upgraded;
 1361: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
 1362: option;
 1363: - LAST is now disabled in the main loop of INT intrinsic;
 1364: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
 1365: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
 1366: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
 1367: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
 1368: in 0);
 1369: - LAST is disabled in the main loop of DRAW intrinsic;
 1370: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
 1371: evaluation of an equation, the system stack is returned corrupted to the
 1372: sequencer;
 1373: - the same minor bug is fixed in FOR and START. It only occurs when the limits
 1374: of a loop are not integer or real.
 1375: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

 1382: - readline is upgraded (minor compilation bug with recent gcc);
 1383: - Makefile.am's and configure.in scripts are improved.
 1384: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
 1385: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
 1386: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

 1388: - recherche_type() is rewritten to be faster;
 1389: - gsl is upgraded (release 1.3);
 1390: - ncurses is upgraded and patched (release 5.3);
 1391: - recherche_instruction_suivante() is fixed (string research with included
 1392: '"') and rewritten to be faster;

 1403: - a minor bug is fixed in evaluation subroutine;
 1404: - vim syntax file is improved;
 1405: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
 1406: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
 1407: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
 1408: is a quick and dirty workaround...);
 1409: - RETURN intrinsic is modified to fix a trouble in interactive mode;
 1410: - rplconvert is improved.

 1522: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
 1523: 
 1524: Newton:[~/rpl/rpl] > time make install
