383: * Mon Jun 20 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.0.prerelease.0 (RPL/2)
384: - New variable management is written. Please note that -p flag does not work
385: and all multithread/multitask capabilities have been disabled until this
386: new subsystem shall be validated.
387: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
388: - major bug is fixed in STD format (1E7 sq prints 1);
389: - major bug is fixed in READ intrinsic (socket). This bug was introduced
390: by a new feature in glibc.
391: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
392: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
393: "ALL" IMPLICIT when it runs in interactive mode;
394: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
395: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
396: to use SAVE to manipulate global variables;
397: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
398: subroutines;
399: - fix major memory access violation in evaluation subroutine. Only occurs
400: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
401: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
402: when X was a vector or a table.
403: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)
404: - Gnuplot is upgraded;

413: Known escape sequences are \", \b, \n, \t, \x?? and \\.
414: * Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
415: - Ncurses is upgraded to 5.8;
416: - ALARM is fixed by filling isdst field;
417: - catch ECONNRESET in write intrinsic to return an execution error instead of
418: system one;
419: - fix a typo in HELP intrinsic;
420: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2;

422: - libmtmalloc is now default Solaris allocator;
423: - ncurses is upgraded;
424: - regression introduced by 4.0.19 is fixed in signal management.
425: Interruption1() could be called from itself and raises bus error (on sparc) or
426: segmentation fault;
427: - sqlite is upgraded to 3.7.4;
428: - OpenSSL is upgraded to 1.0.0c;
429: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);
430: - characters are tested in recherche_type() to avoid names like '12+';
431: - gnuplot is upgraded to 4.4.2 due to major bugs.
432: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
433: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
434: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
435: corruption. As internal memory management have been improved, a best fit
436: allocator like ptmalloc3 is not required anymore;
437: - gnuplot is upgraded to 4.4.1;
438: - deadlock is fixed in signal handlers: same mutex was used in standard
439: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
440: and signal handlers. A new signal handler specific mutex is added;
441: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
442: that has to be evaluated by ->NUM;
443: - rplfile build process is modify to be sure that rplfile is not modified
444: after rpl build stage (to be sure that rplfile checksum is not modified after
445: rpl compilation);
446: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
447: modified to remove yacc code and renamed;

449: ABORT now works on eComStation;
450: - sqlite is upgraded to 3.7.2;
451: - bug is fixed in software interrupts. When both process have different PID,
452: parent process was not interrupted if it is not group master process. To fix
453: this bug, SIGINJECT signal is not sent by child process but by control thread
454: in parent process;
455: - minor bug is fixed in data injection (POKE) that does not work as expected
456: when child process is protected by NRPROC.
457: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
458: - --enable-sysv-sems is added to configure script to use SystemV semaphores
459: functions instead of POSIX functions. This function is disabled or forced on
460: systems that does not provide correct POSIX or SysV semaphores subsystem;
461: - a dirty but not quick patch is written to workaround broken siginfo
462: structures. This patch has been successfully tested. It uses a segment of
463: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
464: (Unix PID);
465: - some OpenBSD's hacks are added;
466: - broken siginfo->si_pid field is now checked by configure script;
467: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
468: - random generator is cloned by SPAWN;

475: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
476: - TOKENIZE is now able to convert escape sequences;
477: - ATPOKE and CLRATPOKE new intrinsics are added;
478: - --enable-full-static configure flag is added. With this flag, mysql and
479: postgresql libraries are statically linked in rpl executable;
480: - units Makefile is modified to avoid readline and ncurses usages;
481: - sqlite is upgraded to 3.7.0.1;
482: - units is upgraded to 1.88;
483: - another major bug is fixed in the same variable creation subroutine.
484: Level 0 and 1 variables adresses were swapped when a global variable masked
485: a name of RPL/2 routine;
486: - major bug is fixed in global variable creation subroutine. When a global
487: variable was created and when a local variable existed with the same name,
488: computed address of global variable was wrong;
489: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
490: is forced in front of all libraries.
491: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
492: - BACKTRACE intrinsic is added;
493: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
494: when this structure is included in IFERR/THEN/END structure and when an error is
495: caught;
496: - major bug is fixed in analyse() subroutine. When evaluation() returned error
497: in a compiled program, analyse() caught this error twice and randomly aborted
498: with a segmentation error;
499: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
500: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
501: signals;
502: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
503: matrix.
504: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
505: - minor bug is fixed in evaluation() subroutine. With this patch, same program
506: returns same result with or without -p flag;

511: programs;
512: - some memory leaks are fixed in process management (SPAWN and DETACH);
513: - version verification is added to shared objects;
514: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
515: linux (false mremap() prototype);
516: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
517: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
518: - all '-' are replaced by '_' in random generator list;
519: - minor memory leak is fixed in OPEN intrinsic (socket);
520: - major bug is fixed in IFERR structure. Only occurs in compiled program;
521: - major bug is fixed in copie_objet() and liberation(). Only concerns
522: format in FCH (file descriptor) and SCK (socket descriptor);
523: - debug routines are improved;
524: - PROCID is added;
525: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
526: and to not use swap;
527: - major bug is fixed in sql support. SQL connections were closed in all chield
528: process;
529: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
530: discovered in Solaris thread safe allocators (libmalloc and libumem) that
531: are first fit class allocators. Solaris libmtmalloc works better and is
532: a best fit class allocator but its performance is poor than ptmalloc3
533: performance;
534: - major bug is fixed in ROW+ intrinsic (new row was not added where it
535: should);
536: - minor bugs are fixed in interruptions.c (semaphores values when error is
537: caught);
538: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
539: created by SPAWN;
540: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
541: ATEXIT. If it receives SIGFABORT, it does not;
542: - ONEXIT is renamed in ATEXIT;
543: - ONEXIT new intrinsic is added.

546: This bug only occurs when RPL/2 tries to create a shared or static variable
547: from an expression;
548: - major bug is fixed in copie_etat_processus(). A field that contains
549: information about shared variable was not copied to new processus structure;
550: - some little memory leaks are fixed in evaluation(), recherche_type() and
551: sequenceur(). They only occured when syntax error were caught;
552: - IMPLICIT causes execution error instead system error;
553: - Hurd support is improved but currently broken because Hurd does not support
554: SIG_INFO. Work in progress;
555: - OpenBSD specific support is removed from sources;
556: - support for Mac OS X and Windows/Cygwin is added.
557: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

597: - in formatted file, string format returned a variable length string even if
598: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
599: a variable length string and 'CHARACTER*(n)' a fixed length string;
600: - keyed access files support is added. Currently, only formatted files are
601: supported;
602: - direct access files support is added. Currenlty, these files can only be used
603: in formatted mode;
604: - virtual variables are now writte in UTF-8 and all special characters
605: in string are escaped;
606: - all formatted files are now converted into UTF-8;
607: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
608: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
609: each execution (md5 and sha1 sums) to enhance security. If one of these tools
610: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
611: on a non recoverable system error;
612: - openssl and sqlite3 libraries are added;
613: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
614: variable indicates RPL/2 root directory. If it is not set, root path
615: is given by configure script (d_exec_path);
616: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

649: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
650: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
651: signals sent to main process were not caught because DAEMON did not replace
652: old pid by new one;
653: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
654: evaluation when an error is reported from a subroutine in another subroutine.
655: For example, error was not caught in following program when it is executed with
656: -p option :

658: TEST2 << 0 inv >>
659: - major bug is fixed in variable management. Some local variables were
660: seen as global ones;

662: script file contains a multibyte character;
663: - IN intrinsic is added;
664: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
665: returned false ;

673: - major bug is fixed in -A command line option (NULL character is missing);
674: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
675: made by blocks (1024 bytes). When an incomplete multibyte sequence is
676: encountered at end of block, subroutine aborts with an execution error;
677: - major bug is fixed in OPEN (TCP/IPv4 sockets).
678: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
679: - DISP now locks stdout;
680: - rpliconv is added to replace standard iconv provided by operating system.
681: Indeed, conversion between different encodages requires transliteration
682: that is not offered by some iconv utility;
683: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
684: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

686: - fprintf is replaced by some functions that allow transliterations between
687: locales;
688: - '"' can now be used in strings ("\"");
689: - iconv is called with -c in preprocessor stage. It is done to write
690: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
691: - double free is fixed in liberation() (type SQL, only occurs when locale is
692: set);
693: - LOCALIZATION, UCASE and LCASE are added;

697: used in onLoading from shared library, USE was pushed on stack as algebraic
698: expression;
699: - libiconv is upgraded to 1.13.1;
700: - gnuplot is upgraded to 4.2.6;

703: - pipe() is overwritten by a macro to avoid a system error. Communication
704: between process are done with pipes and these pipes are managed by a
705: specific asynchrone thread. If a script try to create more threads than
706: management thread can destroy, you can quickly achieve maximum number of
707: opened files and pipe() shall return a system error. This macro tries to create
708: pipes. If pipe() function returns an error, macro waits and retries. If
709: number of retries is greater than a hardcoded value, macro returns an error;
710: - major bug (deadlock) is fixed in process and thread management. I hope
711: this bug shall be the last one;
712: - major bug is fixed in DET intrinsic (determinant was computed without LU
713: diagonalization);

719: or thread number;
720: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
721: was called before a pending interruption5 (SIGFSTOP), signal handler uses
722: a freed semaphore and corrupts heap;
723: - CLRERR is added to erase previous errors;
724: - ERRN and ERRM return exception message and number;
725: - major bug is fixed in interruptions.c. All signal are now bufferised
726: when semaphore_liste_threads is null to avoid deadlock. This bug only
727: occured when STOP was sent to a dying thread or process (when this thread or
728: process was running retrait_thread());
729: - matrix rank is computed before matrix inversion;
730: - file locks are added to stdin and stdout. stderr is not locked because
731: all messages written by signal handlers are sent to stderr;

806: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
807: process is killed;
808: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
809: know typeof() intrinsic function. This function is not standard but exists

875: SQLQUERY. With all new programs, you can open a real connection to databases;
876: - NRPROC is added. This new intrinsic is used to catch error from child
877: process. Without NRPROC, any errors returned by child process cause
878: main process to abort;
879: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
880: starts a new process). There are no mutexes in RPL/2 because all spawned process

1150: an algebraic expression;
1151: - --enable-debug is modified. Now, return can be defined to print
1152: on stdout its position in source code (line and function);
1153: - minor bug is fixed in recherche_type(). Don't forget that space
1154: are not significant in algebraic expression:
1155: '12 3+ 12 X' is the same expression than '123+12X';
1156: - src/Makefile.am is modified to avoid double compilation process;
1157: - --enable-final-run-path is added to configure.in script;

1176: - HELP function is rewritten to be more friendly (a la OpenVMS);
1177: - external wrapper (rplplot) is written to force usage of gnuplot provided
1178: by RPL/2 if it is built during build process. If this build does not exist,
1179: it tries to launch regular gnuplot;
1180: - gnuplot is added to source tree to avoid some trouble between preinstalled
1181: gnuplot and release used by RPL/2. This addition to source tree is
1182: required by some incompatibility between gnuplot releases;

1188: not writable;
1189: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1190: error scrutation.

1232: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1233: versions of PROTECT and UNPROTECT that only deal with global variables
1234: (see RCL/SAVE);
1235: - variable management routines have been rewritten. The new ones are
1236: uncompatible with the old ones. Before these changes, a local variable
1237: was exported to a child subroutine, but cannot be modified into this
1238: child subroutine. Now, a local variable is accessible only in its subroutine;
1239: - SAVE intrinsic is added to manipulate global variables;

1558: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1559: on Debian distribution, but since cpp is in the default path, RPL/2 works
1560: fine...);
1561: - NOT is not correctly formatted in formateur.c:
1562: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1563: with a NOTZ function !
1564: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1565: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1567: - RPL/2 is tested with efence and valgrind;
1568: - configure.in script is modified;
1569: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1570: structure. I don't know why this code was compiled by gcc-3.3... Maybe

1630: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1631: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1632: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1649: - SCLS is added;
1650: - DRWS now uses COLS to draw 2D graphics;
1651: - PPAR and SPAR are written. SPAR returns a list that contains the
1652: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1653: statistical variable, or "DISABLED" if its type is not one of the type of
1654: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1655: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1656: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1657: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1658: disabled. Arguments of EXTERNAL are case sensitive because the external
1659: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1660: of known external functions but add the new list to the last. { "all" }
1661: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1662: external names of the known functions;
1663: - mkrplso.in is modified.
1664: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1665: - vim syntax file is upgraded;
1666: - a minor mistake is fixed in recherche_instruction_suivante();
1667: - some minor memory leaks are fixed in recherche_type() function. They only

1676: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1677: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1678: VISIT does not find a name in level 1;
1679: - configure.in script is modified to add a new test (--enable-debug
1680: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1681: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1682: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1683: 'MATRIX' { 2 2 3 } GETR;
1684: - LOGSCALE intrinsic is improved and now, it can be used as
1685: { "main" "auxiliary" X Y } LOGSCALE;
1686: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1687: same than AXES:
1688: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1689: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1690: { { -10 10 } "automatic" } SCALE.
1691: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1692: because it changes only the dimension of the screen. To have a logarithmic
1693: scale, you must use LOGSCALE intrinsic:
1694: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1695: screen on second scale;
1696: - { X X } autoscale and { Y Y } logscale are now invalid;
1697: - *D is added (depth multiplication, for 3D graphics);
1698: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1699: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1700: - a major bug is fixed in GETI instrinsic when it is used with a name
1701: that contains a matrix or a vector (bad upper bounds conditions in
1702: incrementation);
1703: - DISP intrinsic now uses the 33-th flag. When it is not set
1704: (default), a final carriage return is sent to the terminal;
1705: - AXES intrinsic only takes a list that can contains the keywork
1706: "main" or "auxiliary". Before this modification, this keyword was in
1707: the first stack level;
1708: - vim syntax file is upgraded;
1709: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1710: option;
1711: - LAST is now disabled in the main loop of INT intrinsic;
1712: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1713: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1714: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1715: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1716: in 0);
1717: - LAST is disabled in the main loop of DRAW intrinsic;
1718: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1719: evaluation of an equation, the system stack is returned corrupted to the
1720: sequencer;
1721: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1722: of a loop are not integer or real.
1723: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1724: - the compilation stage aborts with an error message when two definitions

1726: add some tests in gestion_variables.c;
1727: - recherche_type() subroutine ad some other connex subroutines are improved.
1728: Now, some syntax errors about object are caught and do not perform sequencer
1729: hangup;

1731: - Makefile.am's and configure.in scripts are improved.
1732: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1733: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1734: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1736: - recherche_type() is rewritten to be faster;
1737: - gsl is upgraded (release 1.3);
1738: - ncurses is upgraded and patched (release 5.3);
1739: - recherche_instruction_suivante() is fixed (string research with included
1740: '"') and rewritten to be faster;

1754: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1755: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1756: is a quick and dirty workaround...);
1757: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1758: - rplconvert is improved.

1866: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1867: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1868: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1869: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1870: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1871:
1872: Newton:[~/rpl/rpl] > time make install
1873: ...
1874: real 338m39.623s
1875: user 324m32.290s
1876: sys 10m47.380s
