316: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
317: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
318: "ALL" IMPLICIT when it runs in interactive mode;
319: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
320: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
321: to use SAVE to manipulate global variables;
322: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
323: subroutines;
324: - fix major memory access violation in evaluation subroutine. Only occurs
325: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
326: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
327: when X was a vector or a table.

358: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
359: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
360: corruption. As internal memory management have been improved, a best fit
361: allocator like ptmalloc3 is not required anymore;
362: - gnuplot is upgraded to 4.4.1;
363: - deadlock is fixed in signal handlers: same mutex was used in standard
364: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
365: and signal handlers. A new signal handler specific mutex is added;
366: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
367: that has to be evaluated by ->NUM;
368: - rplfile build process is modify to be sure that rplfile is not modified
369: after rpl build stage (to be sure that rplfile checksum is not modified after

377: parent process was not interrupted if it is not group master process. To fix
378: this bug, SIGINJECT signal is not sent by child process but by control thread
379: in parent process;
380: - minor bug is fixed in data injection (POKE) that does not work as expected

383: - --enable-sysv-sems is added to configure script to use SystemV semaphores
384: functions instead of POSIX functions. This function is disabled or forced on
385: systems that does not provide correct POSIX or SysV semaphores subsystem;
386: - a dirty but not quick patch is written to workaround broken siginfo
387: structures. This patch has been successfully tested. It uses a segment of
388: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
389: (Unix PID);

409: Level 0 and 1 variables adresses were swapped when a global variable masked
410: a name of RPL/2 routine;
411: - major bug is fixed in global variable creation subroutine. When a global
412: variable was created and when a local variable existed with the same name,
413: computed address of global variable was wrong;
414: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
415: is forced in front of all libraries.

421: - major bug is fixed in analyse() subroutine. When evaluation() returned error
422: in a compiled program, analyse() caught this error twice and randomly aborted
423: with a segmentation error;
424: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
425: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
426: signals;
427: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
428: matrix.

450: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
451: and to not use swap;
452: - major bug is fixed in sql support. SQL connections were closed in all chield
453: process;
454: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
455: discovered in Solaris thread safe allocators (libmalloc and libumem) that
456: are first fit class allocators. Solaris libmtmalloc works better and is
457: a best fit class allocator but its performance is poor than ptmalloc3
458: performance;

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

521: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
522: - in formatted file, string format returned a variable length string even if
523: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
524: a variable length string and 'CHARACTER*(n)' a fixed length string;
525: - keyed access files support is added. Currently, only formatted files are
526: supported;
527: - direct access files support is added. Currenlty, these files can only be used
528: in formatted mode;
529: - virtual variables are now writte in UTF-8 and all special characters
530: in string are escaped;
531: - all formatted files are now converted into UTF-8;
532: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
533: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
534: each execution (md5 and sha1 sums) to enhance security. If one of these tools
535: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
536: on a non recoverable system error;
537: - openssl and sqlite3 libraries are added;
538: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
539: variable indicates RPL/2 root directory. If it is not set, root path
540: is given by configure script (d_exec_path);
541: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

575: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
576: signals sent to main process were not caught because DAEMON did not replace
577: old pid by new one;
578: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
579: evaluation when an error is reported from a subroutine in another subroutine.
580: For example, error was not caught in following program when it is executed with
581: -p option :
582: TEST << iferr TEST2 then end >>
583: TEST2 << 0 inv >>
584: - major bug is fixed in variable management. Some local variables were
585: seen as global ones;
586: - major bug is fixed in rplcore. Rplcore entered in dead lock when
587: script file contains a multibyte character;
588: - IN intrinsic is added;
589: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
590: returned false ;
591: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
592: programs;
593: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
594: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

601: encountered at end of block, subroutine aborts with an execution error;
602: - major bug is fixed in OPEN (TCP/IPv4 sockets).
603: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
604: - DISP now locks stdout;
605: - rpliconv is added to replace standard iconv provided by operating system.
606: Indeed, conversion between different encodages requires transliteration
607: that is not offered by some iconv utility;
608: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
609: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

628: - pipe() is overwritten by a macro to avoid a system error. Communication
629: between process are done with pipes and these pipes are managed by a
630: specific asynchrone thread. If a script try to create more threads than
631: management thread can destroy, you can quickly achieve maximum number of
632: opened files and pipe() shall return a system error. This macro tries to create
633: pipes. If pipe() function returns an error, macro waits and retries. If
634: number of retries is greater than a hardcoded value, macro returns an error;
635: - major bug (deadlock) is fixed in process and thread management. I hope
636: this bug shall be the last one;

647: a freed semaphore and corrupts heap;
648: - CLRERR is added to erase previous errors;
649: - ERRN and ERRM return exception message and number;
650: - major bug is fixed in interruptions.c. All signal are now bufferised

652: occured when STOP was sent to a dying thread or process (when this thread or
653: process was running retrait_thread());
654: - matrix rank is computed before matrix inversion;

775: - YIELD intrinsic is added;
776: - ERRM is fixed. In some cases, ERRM uses some uninitialized pointers;
777: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
778: static variable that is shared by multiple threads;
779: - '->' intrinsic is improved. All object copies have been avoided;
780: - -n flag is added to catch HUP signal. stderr and stdout are redirected
781: to a file, stdin is redirected to /dev/null when control process is killed;
782: - a mutex is added to each object (before this modification,
783: RPL/2 used a global mutex and performances in multithreaded programs were very
784: poor.);
785: - ALARM is now interruptible;
786: - both PUT and PUTI intrinsics are improved and do not copy list and table
787: when nombre_occurrences == 1;

799: that all programs that worked with old SQL intrinsic can now work with
800: SQLQUERY. With all new programs, you can open a real connection to databases;
801: - NRPROC is added. This new intrinsic is used to catch error from child
802: process. Without NRPROC, any errors returned by child process cause
803: main process to abort;
804: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
805: starts a new process). There are no mutexes in RPL/2 because all spawned process
806: use specific context. Nevertheless, shared variables and associated mutexes
807: should be added;
808: - -D flag and DAEMONIZE intrinsic have been added;
809: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

949: When configure is called with --disable-encoding-autodetection, make does not
950: try to detect source encoding. Please, do not use if RPL/2 can be built
951: without this option !
952: - new garbage collector (and more efficient) is written;

1101: - HELP function is rewritten to be more friendly (a la OpenVMS);
1102: - external wrapper (rplplot) is written to force usage of gnuplot provided
1103: by RPL/2 if it is built during build process. If this build does not exist,
1104: it tries to launch regular gnuplot;
1105: - gnuplot is added to source tree to avoid some trouble between preinstalled
1106: gnuplot and release used by RPL/2. This addition to source tree is
1107: required by some incompatibility between gnuplot releases;

1151: - VARS is modified to display variables status (LOCKED/UNLOCKED and
1152: STATIC/VOLATILE/PARAMETER/VARIABLE);
1153: - STATIC and VOLATILE intrinsics are added to specify static variables. A
1154: static variable can be transformed into volatile with VOLATILE.
1155: With STATIC, next variables created by '->' are static;
1156: - PROTECT and UNPROTECT are added to protect variables against write
1157: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1158: versions of PROTECT and UNPROTECT that only deal with global variables
1159: (see RCL/SAVE);

1521: - BESSEL intrinsic is added. Syntax:
1522: 3: type ("J", "K", "I", "Y", "j", "k", "i", "y")
1523: 2: order (integer or real)
1524: 1: x;
1525: - ->Q intrinsic is added;
1526: - major bug is fixed in C->R intrinsic;
1527: - ROW+ and ROW- are added and tested;
1528: - COL+ and COL- are added and tested. Syntax:
1529: 3: matrix
1530: 2: integer (number of column to be inserted)
1531: 1: column matrix to be inserted;
1532: - major bug was discovered in interface_gnuplot(). It only occurs when
1533: the subroutine reduces the graphical depth. It is now fixed;
1534: - Some mistakes are been fixed in vim syntax file;
1535: - SX2, SY2 and SXY are added;
1536: - SX and SY statistical intrinsics are added;

1539: letter, legal, executive;
1540: - PPAR is modified to include current graphic type.
1541: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1542: - SLICESCALE intrinsic is added. Its syntax is
1543: { "automatic" nb_of_levels }
1544: { "discrete" l1 l2 l3 ... }
1545: { "incremental" start incr }
1546: { "incremental" start incr end }
1547: { "automatic" } (default);
1548: - a minor bug (in last stack) is fixed in AXES intrinsic
1549: - flag 52 is used to automatically update graphics;
1550: - man pages are updated;
1551: - evaluation() is modified to perform evaluation of expressions that contain
1552: '=';
1553: - a minor bug is fixed in AXES intrinsic;
1554: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1555: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1556: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1557: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1558: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;
1559: - PLOTTER is added to draw statistical clouds with lines;
1560: - C and H source files now include vim parameters;
1561: - vim syntax file is modified to include new intrinsics;
1562: - static archive is modified to include all required libraries needed by

1564: * Sun May 4 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6i (RPL/2)
1565: - '=' is added and tested;
1566: - XCOL and YCOL are added;
1567: - a minor bug in analyse_syntaxique() is fixed;
1568: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1569: structure. ELSE is modified to return an error when ELSE appears in
1570: an ELSE/END structure;
1571: - a major bug is fixed in CYCLE;
1572: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1573: sequencer continues after the end of this loop;
1574: - SCLS is added;
1575: - DRWS now uses COLS to draw 2D graphics;
1576: - PPAR and SPAR are written. SPAR returns a list that contains the
1577: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1578: statistical variable, or "DISABLED" if its type is not one of the type of
1579: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1580: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1581: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1582: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1583: disabled. Arguments of EXTERNAL are case sensitive because the external
1584: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1585: of known external functions but add the new list to the last. { "all" }
1586: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1587: external names of the known functions;
1588: - mkrplso.in is modified.
1589: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1590: - vim syntax file is upgraded;
1591: - a minor mistake is fixed in recherche_instruction_suivante();
1592: - some minor memory leaks are fixed in recherche_type() function. They only
1593: occurs when a syntax error is detected;
1594: - #error and #warning preprocessor macros are added;
1595: - INCR and DECR are written (with integer or variable argument);
1596: - CSWP and RSWP are added and tested;
1597: - a minor bug is fixed in analyse.c;
1598: - DEBIAN/control is added to build debian package;
1599: - SCALE is fixed and improved ("automatic" keyword);
1600: - PUTC and PUTR new intrinsics are added.
1601: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1602: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1603: VISIT does not find a name in level 1;
1604: - configure.in script is modified to add a new test (--enable-debug
1605: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1606: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1607: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1608: 'MATRIX' { 2 2 3 } GETR;
1609: - LOGSCALE intrinsic is improved and now, it can be used as
1610: { "main" "auxiliary" X Y } LOGSCALE;
1611: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1612: same than AXES:
1613: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1614: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1615: { { -10 10 } "automatic" } SCALE.
1616: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1617: because it changes only the dimension of the screen. To have a logarithmic
1618: scale, you must use LOGSCALE intrinsic:
1619: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1620: screen on second scale;
1621: - { X X } autoscale and { Y Y } logscale are now invalid;
1622: - *D is added (depth multiplication, for 3D graphics);
1623: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1624: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1625: - a major bug is fixed in GETI instrinsic when it is used with a name
1626: that contains a matrix or a vector (bad upper bounds conditions in
1627: incrementation);
1628: - DISP intrinsic now uses the 33-th flag. When it is not set
1629: (default), a final carriage return is sent to the terminal;
1630: - AXES intrinsic only takes a list that can contains the keywork
1631: "main" or "auxiliary". Before this modification, this keyword was in
1632: the first stack level;
1633: - vim syntax file is upgraded;
1634: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1635: option;
1636: - LAST is now disabled in the main loop of INT intrinsic;
1637: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1638: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1639: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1640: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1641: in 0);
1642: - LAST is disabled in the main loop of DRAW intrinsic;
1643: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1644: evaluation of an equation, the system stack is returned corrupted to the
1645: sequencer;
1646: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1647: of a loop are not integer or real.
1648: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1649: - the compilation stage aborts with an error message when two definitions
1650: have the same name. To improve the compilation() subroutine, I have to
1651: add some tests in gestion_variables.c;
1652: - recherche_type() subroutine ad some other connex subroutines are improved.
1653: Now, some syntax errors about object are caught and do not perform sequencer
1654: hangup;

1656: - Makefile.am's and configure.in scripts are improved.
1657: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1658: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1659: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1660: the boxwidth, 1 by default);
1661: - recherche_type() is rewritten to be faster;
1662: - gsl is upgraded (release 1.3);
1663: - ncurses is upgraded and patched (release 5.3);
1664: - recherche_instruction_suivante() is fixed (string research with included
1665: '"') and rewritten to be faster;
1666: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1667: segfault.
1668: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1676: - a minor bug is fixed in evaluation subroutine;
1677: - vim syntax file is improved;
1678: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1679: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1680: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1681: is a quick and dirty workaround...);
1682: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1683: - rplconvert is improved.
1684: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1791: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1792: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1793: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1794: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1795: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1796:
1797: Newton:[~/rpl/rpl] > time make install
1798: ...
1799: real 338m39.623s
1800: user 324m32.290s
