381: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);
382: - characters are tested in recherche_type() to avoid names like '12+';
383: - gnuplot is upgraded to 4.4.2 due to major bugs.
384: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
385: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
386: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
387: corruption. As internal memory management have been improved, a best fit
388: allocator like ptmalloc3 is not required anymore;
389: - gnuplot is upgraded to 4.4.1;
390: - deadlock is fixed in signal handlers: same mutex was used in standard
391: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
392: and signal handlers. A new signal handler specific mutex is added;
393: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
394: that has to be evaluated by ->NUM;
395: - rplfile build process is modify to be sure that rplfile is not modified
396: after rpl build stage (to be sure that rplfile checksum is not modified after
397: rpl compilation);
398: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
399: modified to remove yacc code and renamed;
400: - some workarounds have been written to not use buggy klibc SystemV IPCS.
401: ABORT now works on eComStation;
402: - sqlite is upgraded to 3.7.2;
403: - bug is fixed in software interrupts. When both process have different PID,
404: parent process was not interrupted if it is not group master process. To fix
405: this bug, SIGINJECT signal is not sent by child process but by control thread
406: in parent process;
407: - minor bug is fixed in data injection (POKE) that does not work as expected
408: when child process is protected by NRPROC.
409: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
410: - --enable-sysv-sems is added to configure script to use SystemV semaphores
411: functions instead of POSIX functions. This function is disabled or forced on
412: systems that does not provide correct POSIX or SysV semaphores subsystem;
413: - a dirty but not quick patch is written to workaround broken siginfo
414: structures. This patch has been successfully tested. It uses a segment of
415: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
416: (Unix PID);
417: - some OpenBSD's hacks are added;
418: - broken siginfo->si_pid field is now checked by configure script;
419: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
420: - random generator is cloned by SPAWN;

431: postgresql libraries are statically linked in rpl executable;
432: - units Makefile is modified to avoid readline and ncurses usages;
433: - sqlite is upgraded to 3.7.0.1;
434: - units is upgraded to 1.88;
435: - another major bug is fixed in the same variable creation subroutine.
436: Level 0 and 1 variables adresses were swapped when a global variable masked
437: a name of RPL/2 routine;
438: - major bug is fixed in global variable creation subroutine. When a global
439: variable was created and when a local variable existed with the same name,
440: computed address of global variable was wrong;
441: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
442: is forced in front of all libraries.
443: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
444: - BACKTRACE intrinsic is added;
445: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
446: when this structure is included in IFERR/THEN/END structure and when an error is
447: caught;
448: - major bug is fixed in analyse() subroutine. When evaluation() returned error
449: in a compiled program, analyse() caught this error twice and randomly aborted
450: with a segmentation error;
451: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
452: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
453: signals;
454: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
455: matrix.
456: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

474: format in FCH (file descriptor) and SCK (socket descriptor);
475: - debug routines are improved;
476: - PROCID is added;
477: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
478: and to not use swap;
479: - major bug is fixed in sql support. SQL connections were closed in all chield
480: process;
481: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
482: discovered in Solaris thread safe allocators (libmalloc and libumem) that
483: are first fit class allocators. Solaris libmtmalloc works better and is
484: a best fit class allocator but its performance is poor than ptmalloc3
485: performance;
486: - major bug is fixed in ROW+ intrinsic (new row was not added where it
487: should);
488: - minor bugs are fixed in interruptions.c (semaphores values when error is
489: caught);
490: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
491: created by SPAWN;
492: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
493: ATEXIT. If it receives SIGFABORT, it does not;
494: - ONEXIT is renamed in ATEXIT;

501: information about shared variable was not copied to new processus structure;
502: - some little memory leaks are fixed in evaluation(), recherche_type() and
503: sequenceur(). They only occured when syntax error were caught;
504: - IMPLICIT causes execution error instead system error;
505: - Hurd support is improved but currently broken because Hurd does not support
506: SIG_INFO. Work in progress;
507: - OpenBSD specific support is removed from sources;
508: - support for Mac OS X and Windows/Cygwin is added.
509: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

548: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
549: - in formatted file, string format returned a variable length string even if
550: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
551: a variable length string and 'CHARACTER*(n)' a fixed length string;
552: - keyed access files support is added. Currently, only formatted files are
553: supported;
554: - direct access files support is added. Currenlty, these files can only be used
555: in formatted mode;
556: - virtual variables are now writte in UTF-8 and all special characters
557: in string are escaped;
558: - all formatted files are now converted into UTF-8;
559: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
560: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
561: each execution (md5 and sha1 sums) to enhance security. If one of these tools
562: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
563: on a non recoverable system error;
564: - openssl and sqlite3 libraries are added;
565: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
566: variable indicates RPL/2 root directory. If it is not set, root path
567: is given by configure script (d_exec_path);
568: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

601: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
602: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
603: signals sent to main process were not caught because DAEMON did not replace
604: old pid by new one;
605: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
606: evaluation when an error is reported from a subroutine in another subroutine.
607: For example, error was not caught in following program when it is executed with
608: -p option :
609: TEST << iferr TEST2 then end >>
610: TEST2 << 0 inv >>
611: - major bug is fixed in variable management. Some local variables were
612: seen as global ones;
613: - major bug is fixed in rplcore. Rplcore entered in dead lock when
614: script file contains a multibyte character;
615: - IN intrinsic is added;
616: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
617: returned false ;
618: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
619: programs;
620: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
621: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
622: strings were never closed;
623: - some bugs have been fixed in file management;

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

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

655: - pipe() is overwritten by a macro to avoid a system error. Communication
656: between process are done with pipes and these pipes are managed by a
657: specific asynchrone thread. If a script try to create more threads than
658: management thread can destroy, you can quickly achieve maximum number of
659: opened files and pipe() shall return a system error. This macro tries to create
660: pipes. If pipe() function returns an error, macro waits and retries. If
661: number of retries is greater than a hardcoded value, macro returns an error;
662: - major bug (deadlock) is fixed in process and thread management. I hope
663: this bug shall be the last one;
664: - major bug is fixed in DET intrinsic (determinant was computed without LU
665: diagonalization);

670: - all process management is rewritten to avoid usage of defunct process
671: or thread number;
672: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
673: was called before a pending interruption5 (SIGFSTOP), signal handler uses
674: a freed semaphore and corrupts heap;
675: - CLRERR is added to erase previous errors;
676: - ERRN and ERRM return exception message and number;
677: - major bug is fixed in interruptions.c. All signal are now bufferised
678: when semaphore_liste_threads is null to avoid deadlock. This bug only
679: occured when STOP was sent to a dying thread or process (when this thread or
680: process was running retrait_thread());
681: - matrix rank is computed before matrix inversion;
682: - file locks are added to stdin and stdout. stderr is not locked because
683: all messages written by signal handlers are sent to stderr;

827: SQLQUERY. With all new programs, you can open a real connection to databases;
828: - NRPROC is added. This new intrinsic is used to catch error from child
829: process. Without NRPROC, any errors returned by child process cause
830: main process to abort;
831: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
832: starts a new process). There are no mutexes in RPL/2 because all spawned process
833: use specific context. Nevertheless, shared variables and associated mutexes
834: should be added;

1129: - external wrapper (rplplot) is written to force usage of gnuplot provided
1130: by RPL/2 if it is built during build process. If this build does not exist,
1131: it tries to launch regular gnuplot;
1132: - gnuplot is added to source tree to avoid some trouble between preinstalled
1133: gnuplot and release used by RPL/2. This addition to source tree is
1134: required by some incompatibility between gnuplot releases;

1521: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1522: structure. I don't know why this code was compiled by gcc-3.3... Maybe
1523: another gcc bug...
1524: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)

1568: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1569: - SLICESCALE intrinsic is added. Its syntax is
1570: { "automatic" nb_of_levels }
1571: { "discrete" l1 l2 l3 ... }
1572: { "incremental" start incr }
1573: { "incremental" start incr end }
1574: { "automatic" } (default);

1576: - flag 52 is used to automatically update graphics;
1577: - man pages are updated;
1578: - evaluation() is modified to perform evaluation of expressions that contain
1579: '=';
1580: - a minor bug is fixed in AXES intrinsic;
1581: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1582: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1583: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1584: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1585: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1601: - SCLS is added;
1602: - DRWS now uses COLS to draw 2D graphics;
1603: - PPAR and SPAR are written. SPAR returns a list that contains the
1604: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1605: statistical variable, or "DISABLED" if its type is not one of the type of
1606: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1607: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1608: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1609: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1610: disabled. Arguments of EXTERNAL are case sensitive because the external
1611: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1612: of known external functions but add the new list to the last. { "all" }
1613: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1614: external names of the known functions;
1615: - mkrplso.in is modified.
1616: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1617: - vim syntax file is upgraded;
1618: - a minor mistake is fixed in recherche_instruction_suivante();
1619: - some minor memory leaks are fixed in recherche_type() function. They only
1620: occurs when a syntax error is detected;

1626: - SCALE is fixed and improved ("automatic" keyword);
1627: - PUTC and PUTR new intrinsics are added.
1628: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1629: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1630: VISIT does not find a name in level 1;
1631: - configure.in script is modified to add a new test (--enable-debug
1632: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1633: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1634: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1635: 'MATRIX' { 2 2 3 } GETR;
1636: - LOGSCALE intrinsic is improved and now, it can be used as
1637: { "main" "auxiliary" X Y } LOGSCALE;
1638: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1639: same than AXES:
1640: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1641: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1642: { { -10 10 } "automatic" } SCALE.
1643: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1644: because it changes only the dimension of the screen. To have a logarithmic
1645: scale, you must use LOGSCALE intrinsic:
1646: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1647: screen on second scale;
1648: - { X X } autoscale and { Y Y } logscale are now invalid;
1649: - *D is added (depth multiplication, for 3D graphics);
1650: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1651: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1652: - a major bug is fixed in GETI instrinsic when it is used with a name
1653: that contains a matrix or a vector (bad upper bounds conditions in
1654: incrementation);
1655: - DISP intrinsic now uses the 33-th flag. When it is not set
1656: (default), a final carriage return is sent to the terminal;
1657: - AXES intrinsic only takes a list that can contains the keywork
1658: "main" or "auxiliary". Before this modification, this keyword was in
1659: the first stack level;
1660: - vim syntax file is upgraded;
1661: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1662: option;
1663: - LAST is now disabled in the main loop of INT intrinsic;
1664: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1665: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1666: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1667: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1668: in 0);
1669: - LAST is disabled in the main loop of DRAW intrinsic;
1670: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1671: evaluation of an equation, the system stack is returned corrupted to the
1672: sequencer;
1673: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1674: of a loop are not integer or real.
1675: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1676: - the compilation stage aborts with an error message when two definitions
1677: have the same name. To improve the compilation() subroutine, I have to
1678: add some tests in gestion_variables.c;
1679: - recherche_type() subroutine ad some other connex subroutines are improved.
1680: Now, some syntax errors about object are caught and do not perform sequencer
1681: hangup;

1683: - Makefile.am's and configure.in scripts are improved.
1684: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1685: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1686: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1687: the boxwidth, 1 by default);
1688: - recherche_type() is rewritten to be faster;
1689: - gsl is upgraded (release 1.3);
1690: - ncurses is upgraded and patched (release 5.3);
1691: - recherche_instruction_suivante() is fixed (string research with included
1692: '"') and rewritten to be faster;
1693: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1694: segfault.
1695: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1703: - a minor bug is fixed in evaluation subroutine;
1704: - vim syntax file is improved;
1705: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1706: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1707: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1708: is a quick and dirty workaround...);
1709: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1710: - rplconvert is improved.
1711: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1727: Now, an expression such as 'A+' returns an error when it is analyzed;
1728: - VISIT intrinsic is added;
1729: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1730: normal mode.

1818: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1819: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1820: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1821: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1822: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1823:
1824: Newton:[~/rpl/rpl] > time make install
1825: ...
1826: real 338m39.623s
1827: user 324m32.290s

1831: I don't know if you will compile this language on old worstations, but
1832: it is usable ;-) ;
1833: - SYSEVAL is improved. An external program can be called without any shell.
