446: - major bug is fixed in STD format (1E7 sq prints 1);
447: - major bug is fixed in READ intrinsic (socket). This bug was introduced
448: by a new feature in glibc.
449: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
450: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
451: "ALL" IMPLICIT when it runs in interactive mode;
452: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
453: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
454: to use SAVE to manipulate global variables;
455: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
456: subroutines;
457: - fix major memory access violation in evaluation subroutine. Only occurs
458: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
459: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
460: when X was a vector or a table.

490: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
491: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
492: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
493: corruption. As internal memory management have been improved, a best fit
494: allocator like ptmalloc3 is not required anymore;
495: - gnuplot is upgraded to 4.4.1;
496: - deadlock is fixed in signal handlers: same mutex was used in standard
497: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
498: and signal handlers. A new signal handler specific mutex is added;
499: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
500: that has to be evaluated by ->NUM;
501: - rplfile build process is modify to be sure that rplfile is not modified
502: after rpl build stage (to be sure that rplfile checksum is not modified after

511: this bug, SIGINJECT signal is not sent by child process but by control thread
512: in parent process;
513: - minor bug is fixed in data injection (POKE) that does not work as expected
514: when child process is protected by NRPROC.
515: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
516: - --enable-sysv-sems is added to configure script to use SystemV semaphores
517: functions instead of POSIX functions. This function is disabled or forced on
518: systems that does not provide correct POSIX or SysV semaphores subsystem;
519: - a dirty but not quick patch is written to workaround broken siginfo
520: structures. This patch has been successfully tested. It uses a segment of
521: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
522: (Unix PID);
523: - some OpenBSD's hacks are added;
524: - broken siginfo->si_pid field is now checked by configure script;

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

550: - BACKTRACE intrinsic is added;
551: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
552: when this structure is included in IFERR/THEN/END structure and when an error is
553: caught;
554: - major bug is fixed in analyse() subroutine. When evaluation() returned error
555: in a compiled program, analyse() caught this error twice and randomly aborted
556: with a segmentation error;
557: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
558: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
559: signals;
560: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
561: matrix.

580: format in FCH (file descriptor) and SCK (socket descriptor);
581: - debug routines are improved;
582: - PROCID is added;
583: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
584: and to not use swap;
585: - major bug is fixed in sql support. SQL connections were closed in all chield
586: process;
587: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
588: discovered in Solaris thread safe allocators (libmalloc and libumem) that
589: are first fit class allocators. Solaris libmtmalloc works better and is
590: a best fit class allocator but its performance is poor than ptmalloc3
591: performance;
592: - major bug is fixed in ROW+ intrinsic (new row was not added where it
593: should);
594: - minor bugs are fixed in interruptions.c (semaphores values when error is
595: caught);
596: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
597: created by SPAWN;

607: information about shared variable was not copied to new processus structure;
608: - some little memory leaks are fixed in evaluation(), recherche_type() and
609: sequenceur(). They only occured when syntax error were caught;
610: - IMPLICIT causes execution error instead system error;
611: - Hurd support is improved but currently broken because Hurd does not support
612: SIG_INFO. Work in progress;
613: - OpenBSD specific support is removed from sources;
614: - support for Mac OS X and Windows/Cygwin is added.

666: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
667: each execution (md5 and sha1 sums) to enhance security. If one of these tools
668: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
669: on a non recoverable system error;
670: - openssl and sqlite3 libraries are added;
671: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
672: variable indicates RPL/2 root directory. If it is not set, root path
673: is given by configure script (d_exec_path);

709: signals sent to main process were not caught because DAEMON did not replace
710: old pid by new one;
711: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
712: evaluation when an error is reported from a subroutine in another subroutine.
713: For example, error was not caught in following program when it is executed with

762: between process are done with pipes and these pipes are managed by a
763: specific asynchrone thread. If a script try to create more threads than
764: management thread can destroy, you can quickly achieve maximum number of
765: opened files and pipe() shall return a system error. This macro tries to create
766: pipes. If pipe() function returns an error, macro waits and retries. If
767: number of retries is greater than a hardcoded value, macro returns an error;
768: - major bug (deadlock) is fixed in process and thread management. I hope
769: this bug shall be the last one;
770: - major bug is fixed in DET intrinsic (determinant was computed without LU
771: diagonalization);
772: - SWAPCNTXT is added;
773: - minor bug is fixed in Makefile.am (licences rule).
774: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
775: - some bugfixes are added in process management;
776: - all process management is rewritten to avoid usage of defunct process
777: or thread number;

780: a freed semaphore and corrupts heap;
781: - CLRERR is added to erase previous errors;
782: - ERRN and ERRM return exception message and number;
783: - major bug is fixed in interruptions.c. All signal are now bufferised
784: when semaphore_liste_threads is null to avoid deadlock. This bug only
785: occured when STOP was sent to a dying thread or process (when this thread or
786: process was running retrait_thread());
787: - matrix rank is computed before matrix inversion;
788: - file locks are added to stdin and stdout. stderr is not locked because
789: all messages written by signal handlers are sent to stderr;
790: - configure.in script is modified to test gcc version and avoid a bug in
791: gcc older than 4.4;
792: - some benchmarks have been done :

864: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
865: process is killed;
866: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
867: know typeof() intrinsic function. This function is not standard but exists
868: under Sun Studio, gcc, and maybe some others compilers. If this function does
869: not exist on your compiler, you can change its definition by old one in
870: src/rpl.h;
871: - fflush() can now be interrupted by signal (SunOS);

893: deadlock when a huge amount of threads is launched);
894: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
895: arguments types are unsupported;
896: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

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

932: that all programs that worked with old SQL intrinsic can now work with
933: SQLQUERY. With all new programs, you can open a real connection to databases;
934: - NRPROC is added. This new intrinsic is used to catch error from child
935: process. Without NRPROC, any errors returned by child process cause
936: main process to abort;
937: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
938: starts a new process). There are no mutexes in RPL/2 because all spawned process
939: use specific context. Nevertheless, shared variables and associated mutexes
940: should be added;
941: - -D flag and DAEMONIZE intrinsic have been added;

1079: before starting interrupt evaluation;
1080: - -f parameter is added when iconv is called;
1081: - as old file program was bugged, a new option is added to configure script.
1082: When configure is called with --disable-encoding-autodetection, make does not

1122: than 1E6;
1123: - numeric and character formats are now tested;
1124: - -A flag is added. -A is used to give command line parameters to main
1125: routine. Example:

1211: - minor bug is fixed in recherche_type(). Don't forget that space
1212: are not significant in algebraic expression:
1213: '12 3+ 12 X' is the same expression than '123+12X';
1214: - src/Makefile.am is modified to avoid double compilation process;
1215: - --enable-final-run-path is added to configure.in script;

1234: - HELP function is rewritten to be more friendly (a la OpenVMS);
1235: - external wrapper (rplplot) is written to force usage of gnuplot provided
1236: by RPL/2 if it is built during build process. If this build does not exist,
1237: it tries to launch regular gnuplot;
1238: - gnuplot is added to source tree to avoid some trouble between preinstalled
1239: gnuplot and release used by RPL/2. This addition to source tree is

1293: - variable management routines have been rewritten. The new ones are
1294: uncompatible with the old ones. Before these changes, a local variable
1295: was exported to a child subroutine, but cannot be modified into this
1296: child subroutine. Now, a local variable is accessible only in its subroutine;

1618: fine...);
1619: - NOT is not correctly formatted in formateur.c:
1620: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1621: with a NOTZ function !
1622: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1623: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1625: - RPL/2 is tested with efence and valgrind;
1626: - configure.in script is modified;
1627: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1688: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1689: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1690: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1707: - SCLS is added;
1708: - DRWS now uses COLS to draw 2D graphics;
1709: - PPAR and SPAR are written. SPAR returns a list that contains the
1710: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1711: statistical variable, or "DISABLED" if its type is not one of the type of
1712: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1713: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1714: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1715: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1716: disabled. Arguments of EXTERNAL are case sensitive because the external
1717: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1718: of known external functions but add the new list to the last. { "all" }
1719: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1720: external names of the known functions;
1721: - mkrplso.in is modified.
1722: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1723: - vim syntax file is upgraded;
1724: - a minor mistake is fixed in recherche_instruction_suivante();
1725: - some minor memory leaks are fixed in recherche_type() function. They only

1734: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1735: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1736: VISIT does not find a name in level 1;
1737: - configure.in script is modified to add a new test (--enable-debug
1738: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1739: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1740: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1741: 'MATRIX' { 2 2 3 } GETR;
1742: - LOGSCALE intrinsic is improved and now, it can be used as
1743: { "main" "auxiliary" X Y } LOGSCALE;
1744: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1745: same than AXES:
1746: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1747: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1748: { { -10 10 } "automatic" } SCALE.
1749: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1750: because it changes only the dimension of the screen. To have a logarithmic
1751: scale, you must use LOGSCALE intrinsic:
1752: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1753: screen on second scale;
1754: - { X X } autoscale and { Y Y } logscale are now invalid;
1755: - *D is added (depth multiplication, for 3D graphics);
1756: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1757: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1758: - a major bug is fixed in GETI instrinsic when it is used with a name
1759: that contains a matrix or a vector (bad upper bounds conditions in
1760: incrementation);
1761: - DISP intrinsic now uses the 33-th flag. When it is not set
1762: (default), a final carriage return is sent to the terminal;
1763: - AXES intrinsic only takes a list that can contains the keywork
1764: "main" or "auxiliary". Before this modification, this keyword was in
1765: the first stack level;
1766: - vim syntax file is upgraded;
1767: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1768: option;
1769: - LAST is now disabled in the main loop of INT intrinsic;
1770: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1771: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1772: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1773: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1774: in 0);
1775: - LAST is disabled in the main loop of DRAW intrinsic;
1776: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1777: evaluation of an equation, the system stack is returned corrupted to the
1778: sequencer;
1779: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1780: of a loop are not integer or real.
1781: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1782: - the compilation stage aborts with an error message when two definitions
1783: have the same name. To improve the compilation() subroutine, I have to
1784: add some tests in gestion_variables.c;
1785: - recherche_type() subroutine ad some other connex subroutines are improved.
1786: Now, some syntax errors about object are caught and do not perform sequencer
1787: hangup;
1788: - readline is upgraded (minor compilation bug with recent gcc);
1789: - Makefile.am's and configure.in scripts are improved.
1790: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1791: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1792: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1793: the boxwidth, 1 by default);
1794: - recherche_type() is rewritten to be faster;
1795: - gsl is upgraded (release 1.3);
1796: - ncurses is upgraded and patched (release 5.3);
1797: - recherche_instruction_suivante() is fixed (string research with included
1798: '"') and rewritten to be faster;
1799: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1800: segfault.
1801: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1809: - a minor bug is fixed in evaluation subroutine;
1810: - vim syntax file is improved;
1811: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1812: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1813: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1814: is a quick and dirty workaround...);
1815: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1816: - rplconvert is improved.

1833: Now, an expression such as 'A+' returns an error when it is analyzed;
1834: - VISIT intrinsic is added;
1835: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1836: normal mode.

1898: deleted too!;
1899: - configure script is improved (and it seems to be good ;-) );
1900: - An --disable-experimental flag is added to the configure script. Thus, even
1901: if you compile a beta release, you can compile a stable RPL/2;
1902: - new syntax and ftplugin written for vim 6.0.

1915: that the RPL/2 seqencer must stop and must give a prompt. This
1916: signal is an asynchonous "HALT" command;
1917: - SIGINT (CTRL+C) variables stack corruption is fixed;
1918: - IFERR seems to be fixed (in equation evaluation routine);
1919: - Memory leak is fixed (ADR object type);
1920: - DATE returns both date and hours;

1925: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1926: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1927: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1928: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1929:
1930: Newton:[~/rpl/rpl] > time make install
1931: ...
1932: real 338m39.623s
1933: user 324m32.290s
1934: sys 10m47.380s
1935: Newton:[~/rpl/rpl] >
1936:
1937: I don't know if you will compile this language on old worstations, but
1938: it is usable ;-) ;
1939: - SYSEVAL is improved. An external program can be called without any shell.
1940: Thus, even if the sticky bit is set, RPL/2 can not give a shell root when
