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

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

375: this bug, SIGINJECT signal is not sent by child process but by control thread
376: in parent process;
377: - minor bug is fixed in data injection (POKE) that does not work as expected
378: when child process is protected by NRPROC.

380: - --enable-sysv-sems is added to configure script to use SystemV semaphores
381: functions instead of POSIX functions. This function is disabled or forced on
382: systems that does not provide correct POSIX or SysV semaphores subsystem;
383: - a dirty but not quick patch is written to workaround broken siginfo
384: structures. This patch has been successfully tested. It uses a segment of
385: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
386: (Unix PID);
387: - some OpenBSD's hacks are added;
388: - broken siginfo->si_pid field is now checked by configure script;
389: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

406: Level 0 and 1 variables adresses were swapped when a global variable masked
407: a name of RPL/2 routine;
408: - major bug is fixed in global variable creation subroutine. When a global
409: variable was created and when a local variable existed with the same name,
410: computed address of global variable was wrong;
411: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
412: is forced in front of all libraries.
413: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
414: - BACKTRACE intrinsic is added;

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

446: - PROCID is added;
447: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
448: and to not use swap;
449: - major bug is fixed in sql support. SQL connections were closed in all chield
450: process;
451: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
452: discovered in Solaris thread safe allocators (libmalloc and libumem) that
453: are first fit class allocators. Solaris libmtmalloc works better and is
454: a best fit class allocator but its performance is poor than ptmalloc3
455: performance;
456: - major bug is fixed in ROW+ intrinsic (new row was not added where it
457: should);
458: - minor bugs are fixed in interruptions.c (semaphores values when error is

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

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

572: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
573: signals sent to main process were not caught because DAEMON did not replace
574: old pid by new one;
575: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
576: evaluation when an error is reported from a subroutine in another subroutine.
577: For example, error was not caught in following program when it is executed with
578: -p option :
579: TEST << iferr TEST2 then end >>
580: TEST2 << 0 inv >>
581: - major bug is fixed in variable management. Some local variables were
582: seen as global ones;

584: script file contains a multibyte character;
585: - IN intrinsic is added;
586: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
587: returned false ;

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

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

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

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

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

796: that all programs that worked with old SQL intrinsic can now work with
797: SQLQUERY. With all new programs, you can open a real connection to databases;
798: - NRPROC is added. This new intrinsic is used to catch error from child
799: process. Without NRPROC, any errors returned by child process cause
800: main process to abort;
801: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
802: starts a new process). There are no mutexes in RPL/2 because all spawned process
803: use specific context. Nevertheless, shared variables and associated mutexes
804: should be added;

824: should not be used in regular programs;
825: - SWISTATUS is written;
826: - WFACK is written;
827: - rplcore files are now able to handle compilation errors;

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

1098: - HELP function is rewritten to be more friendly (a la OpenVMS);
1099: - external wrapper (rplplot) is written to force usage of gnuplot provided
1100: by RPL/2 if it is built during build process. If this build does not exist,
1101: it tries to launch regular gnuplot;
1102: - gnuplot is added to source tree to avoid some trouble between preinstalled
1103: gnuplot and release used by RPL/2. This addition to source tree is
1104: required by some incompatibility between gnuplot releases;

1147: - configure.in script is added in lapack subtree;
1148: - VARS is modified to display variables status (LOCKED/UNLOCKED and
1149: STATIC/VOLATILE/PARAMETER/VARIABLE);
1150: - STATIC and VOLATILE intrinsics are added to specify static variables. A
1151: static variable can be transformed into volatile with VOLATILE.
1152: With STATIC, next variables created by '->' are static;
1153: - PROTECT and UNPROTECT are added to protect variables against write
1154: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1155: versions of PROTECT and UNPROTECT that only deal with global variables
1156: (see RCL/SAVE);
1157: - variable management routines have been rewritten. The new ones are

1518: - BESSEL intrinsic is added. Syntax:
1519: 3: type ("J", "K", "I", "Y", "j", "k", "i", "y")
1520: 2: order (integer or real)
1521: 1: x;
1522: - ->Q intrinsic is added;
1523: - major bug is fixed in C->R intrinsic;
1524: - ROW+ and ROW- are added and tested;
1525: - COL+ and COL- are added and tested. Syntax:
1526: 3: matrix
1527: 2: integer (number of column to be inserted)
1528: 1: column matrix to be inserted;
1529: - major bug was discovered in interface_gnuplot(). It only occurs when
1530: the subroutine reduces the graphical depth. It is now fixed;
1531: - Some mistakes are been fixed in vim syntax file;
1532: - SX2, SY2 and SXY are added;
1533: - SX and SY statistical intrinsics are added;

1536: letter, legal, executive;
1537: - PPAR is modified to include current graphic type.
1538: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1539: - SLICESCALE intrinsic is added. Its syntax is
1540: { "automatic" nb_of_levels }
1541: { "discrete" l1 l2 l3 ... }
1542: { "incremental" start incr }
1543: { "incremental" start incr end }
1544: { "automatic" } (default);
1545: - a minor bug (in last stack) is fixed in AXES intrinsic
1546: - flag 52 is used to automatically update graphics;
1547: - man pages are updated;
1548: - evaluation() is modified to perform evaluation of expressions that contain
1549: '=';
1550: - a minor bug is fixed in AXES intrinsic;
1551: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1552: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1553: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1554: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1555: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;
1556: - PLOTTER is added to draw statistical clouds with lines;
1557: - C and H source files now include vim parameters;
1558: - vim syntax file is modified to include new intrinsics;
1559: - static archive is modified to include all required libraries needed by

1562: - '=' is added and tested;
1563: - XCOL and YCOL are added;
1564: - a minor bug in analyse_syntaxique() is fixed;
1565: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1566: structure. ELSE is modified to return an error when ELSE appears in
1567: an ELSE/END structure;
1568: - a major bug is fixed in CYCLE;
1569: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1570: sequencer continues after the end of this loop;
1571: - SCLS is added;
1572: - DRWS now uses COLS to draw 2D graphics;
1573: - PPAR and SPAR are written. SPAR returns a list that contains the
1574: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1575: statistical variable, or "DISABLED" if its type is not one of the type of
1576: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1577: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1578: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1579: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1580: disabled. Arguments of EXTERNAL are case sensitive because the external
1581: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1582: of known external functions but add the new list to the last. { "all" }
1583: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1584: external names of the known functions;
1585: - mkrplso.in is modified.
1586: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1587: - vim syntax file is upgraded;
1588: - a minor mistake is fixed in recherche_instruction_suivante();
1589: - some minor memory leaks are fixed in recherche_type() function. They only
1590: occurs when a syntax error is detected;
1591: - #error and #warning preprocessor macros are added;
1592: - INCR and DECR are written (with integer or variable argument);
1593: - CSWP and RSWP are added and tested;
1594: - a minor bug is fixed in analyse.c;
1595: - DEBIAN/control is added to build debian package;
1596: - SCALE is fixed and improved ("automatic" keyword);
1597: - PUTC and PUTR new intrinsics are added.
1598: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1599: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1600: VISIT does not find a name in level 1;
1601: - configure.in script is modified to add a new test (--enable-debug
1602: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1603: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1604: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1605: 'MATRIX' { 2 2 3 } GETR;
1606: - LOGSCALE intrinsic is improved and now, it can be used as
1607: { "main" "auxiliary" X Y } LOGSCALE;
1608: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1609: same than AXES:
1610: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1611: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1612: { { -10 10 } "automatic" } SCALE.
1613: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1614: because it changes only the dimension of the screen. To have a logarithmic
1615: scale, you must use LOGSCALE intrinsic:
1616: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1617: screen on second scale;
1618: - { X X } autoscale and { Y Y } logscale are now invalid;
1619: - *D is added (depth multiplication, for 3D graphics);
1620: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1621: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1622: - a major bug is fixed in GETI instrinsic when it is used with a name
1623: that contains a matrix or a vector (bad upper bounds conditions in
1624: incrementation);
1625: - DISP intrinsic now uses the 33-th flag. When it is not set
1626: (default), a final carriage return is sent to the terminal;
1627: - AXES intrinsic only takes a list that can contains the keywork
1628: "main" or "auxiliary". Before this modification, this keyword was in
1629: the first stack level;
1630: - vim syntax file is upgraded;
1631: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1632: option;
1633: - LAST is now disabled in the main loop of INT intrinsic;
1634: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1635: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1636: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1637: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1638: in 0);
1639: - LAST is disabled in the main loop of DRAW intrinsic;
1640: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1641: evaluation of an equation, the system stack is returned corrupted to the
1642: sequencer;
1643: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1644: of a loop are not integer or real.
1645: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1646: - the compilation stage aborts with an error message when two definitions
1647: have the same name. To improve the compilation() subroutine, I have to
1648: add some tests in gestion_variables.c;
1649: - recherche_type() subroutine ad some other connex subroutines are improved.
1650: Now, some syntax errors about object are caught and do not perform sequencer
1651: hangup;

1653: - Makefile.am's and configure.in scripts are improved.
1654: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1655: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1656: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1657: the boxwidth, 1 by default);
1658: - recherche_type() is rewritten to be faster;
1659: - gsl is upgraded (release 1.3);
1660: - ncurses is upgraded and patched (release 5.3);
1661: - recherche_instruction_suivante() is fixed (string research with included
1662: '"') and rewritten to be faster;
1663: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1664: segfault.

1673: - a minor bug is fixed in evaluation subroutine;
1674: - vim syntax file is improved;
1675: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1676: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1677: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1678: is a quick and dirty workaround...);
1679: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1680: - rplconvert is improved.
1681: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1697: Now, an expression such as 'A+' returns an error when it is analyzed;
1698: - VISIT intrinsic is added;
1699: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1700: normal mode.

1788: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1789: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1790: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1791: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1792: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1793:
1794: Newton:[~/rpl/rpl] > time make install
1795: ...
1796: real 338m39.623s
1797: user 324m32.290s
