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

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

548: parent process was not interrupted if it is not group master process. To fix
549: this bug, SIGINJECT signal is not sent by child process but by control thread
550: in parent process;
551: - minor bug is fixed in data injection (POKE) that does not work as expected
552: when child process is protected by NRPROC.
553: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
554: - --enable-sysv-sems is added to configure script to use SystemV semaphores
555: functions instead of POSIX functions. This function is disabled or forced on
556: systems that does not provide correct POSIX or SysV semaphores subsystem;
557: - a dirty but not quick patch is written to workaround broken siginfo
558: structures. This patch has been successfully tested. It uses a segment of
559: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
560: (Unix PID);
561: - some OpenBSD's hacks are added;
562: - broken siginfo->si_pid field is now checked by configure script;

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

590: when this structure is included in IFERR/THEN/END structure and when an error is
591: caught;
592: - major bug is fixed in analyse() subroutine. When evaluation() returned error
593: in a compiled program, analyse() caught this error twice and randomly aborted
594: with a segmentation error;
595: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
596: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
597: signals;
598: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
599: matrix.

621: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
622: and to not use swap;
623: - major bug is fixed in sql support. SQL connections were closed in all chield
624: process;
625: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
626: discovered in Solaris thread safe allocators (libmalloc and libumem) that
627: are first fit class allocators. Solaris libmtmalloc works better and is
628: a best fit class allocator but its performance is poor than ptmalloc3
629: performance;
630: - major bug is fixed in ROW+ intrinsic (new row was not added where it
631: should);
632: - minor bugs are fixed in interruptions.c (semaphores values when error is

645: information about shared variable was not copied to new processus structure;
646: - some little memory leaks are fixed in evaluation(), recherche_type() and
647: sequenceur(). They only occured when syntax error were caught;
648: - IMPLICIT causes execution error instead system error;

704: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
705: each execution (md5 and sha1 sums) to enhance security. If one of these tools
706: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
707: on a non recoverable system error;
708: - openssl and sqlite3 libraries are added;
709: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this

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

769: - major bug is fixed in -A command line option (NULL character is missing);
770: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
771: made by blocks (1024 bytes). When an incomplete multibyte sequence is
772: encountered at end of block, subroutine aborts with an execution error;
773: - major bug is fixed in OPEN (TCP/IPv4 sockets).
774: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
775: - DISP now locks stdout;
776: - rpliconv is added to replace standard iconv provided by operating system.
777: Indeed, conversion between different encodages requires transliteration
778: that is not offered by some iconv utility;
779: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
780: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
781: not be found), SYSEVAL enters in a dead lock;
782: - fprintf is replaced by some functions that allow transliterations between
783: locales;
784: - '"' can now be used in strings ("\"");
785: - iconv is called with -c in preprocessor stage. It is done to write
786: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
787: - double free is fixed in liberation() (type SQL, only occurs when locale is
788: set);
789: - LOCALIZATION, UCASE and LCASE are added;
790: - major bug is fixed in EXIT intrinsic that was able to return a false
791: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
792: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
793: used in onLoading from shared library, USE was pushed on stack as algebraic
794: expression;
795: - libiconv is upgraded to 1.13.1;
796: - gnuplot is upgraded to 4.2.6;
797: - gsl is upgraded to 1.13.
798: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
799: - pipe() is overwritten by a macro to avoid a system error. Communication
800: between process are done with pipes and these pipes are managed by a
801: specific asynchrone thread. If a script try to create more threads than
802: management thread can destroy, you can quickly achieve maximum number of
803: opened files and pipe() shall return a system error. This macro tries to create
804: pipes. If pipe() function returns an error, macro waits and retries. If
805: number of retries is greater than a hardcoded value, macro returns an error;
806: - major bug (deadlock) is fixed in process and thread management. I hope
807: this bug shall be the last one;
808: - major bug is fixed in DET intrinsic (determinant was computed without LU
809: diagonalization);
810: - SWAPCNTXT is added;
811: - minor bug is fixed in Makefile.am (licences rule).
812: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
813: - some bugfixes are added in process management;
814: - all process management is rewritten to avoid usage of defunct process
815: or thread number;
816: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
817: was called before a pending interruption5 (SIGFSTOP), signal handler uses
818: a freed semaphore and corrupts heap;
819: - CLRERR is added to erase previous errors;
820: - ERRN and ERRM return exception message and number;
821: - major bug is fixed in interruptions.c. All signal are now bufferised
822: when semaphore_liste_threads is null to avoid deadlock. This bug only
823: occured when STOP was sent to a dying thread or process (when this thread or
824: process was running retrait_thread());
825: - matrix rank is computed before matrix inversion;
826: - file locks are added to stdin and stdout. stderr is not locked because
827: all messages written by signal handlers are sent to stderr;
828: - configure.in script is modified to test gcc version and avoid a bug in
829: gcc older than 4.4;
830: - some benchmarks have been done :

902: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
903: process is killed;
904: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
905: know typeof() intrinsic function. This function is not standard but exists
906: under Sun Studio, gcc, and maybe some others compilers. If this function does
907: not exist on your compiler, you can change its definition by old one in
908: src/rpl.h;
909: - fflush() can now be interrupted by signal (SunOS);
910: - fflush(NULL) is called before all fork() occurrences;

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

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

970: that all programs that worked with old SQL intrinsic can now work with
971: SQLQUERY. With all new programs, you can open a real connection to databases;
972: - NRPROC is added. This new intrinsic is used to catch error from child
973: process. Without NRPROC, any errors returned by child process cause
974: main process to abort;
975: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
976: starts a new process). There are no mutexes in RPL/2 because all spawned process
977: use specific context. Nevertheless, shared variables and associated mutexes
978: should be added;
979: - -D flag and DAEMONIZE intrinsic have been added;
980: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

1117: before starting interrupt evaluation;
1118: - -f parameter is added when iconv is called;
1119: - as old file program was bugged, a new option is added to configure script.

1122: without this option !
1123: - new garbage collector (and more efficient) is written;
1124: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1125: not support real time signals, RPL/2 cannot use multitasking functions;
1126: - error returned by preprocessor are now catched by RPL/2;
1127: - -p option is added. With this option, all scripts are compiled before
1128: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run

1272: - HELP function is rewritten to be more friendly (a la OpenVMS);
1273: - external wrapper (rplplot) is written to force usage of gnuplot provided
1274: by RPL/2 if it is built during build process. If this build does not exist,
1275: it tries to launch regular gnuplot;
1276: - gnuplot is added to source tree to avoid some trouble between preinstalled
1277: gnuplot and release used by RPL/2. This addition to source tree is
1278: required by some incompatibility between gnuplot releases;

1328: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1329: versions of PROTECT and UNPROTECT that only deal with global variables
1330: (see RCL/SAVE);
1331: - variable management routines have been rewritten. The new ones are
1332: uncompatible with the old ones. Before these changes, a local variable
1333: was exported to a child subroutine, but cannot be modified into this
1334: child subroutine. Now, a local variable is accessible only in its subroutine;
1335: - SAVE intrinsic is added to manipulate global variables;

1656: fine...);
1657: - NOT is not correctly formatted in formateur.c:
1658: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1659: with a NOTZ function !
1660: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1663: - RPL/2 is tested with efence and valgrind;
1664: - configure.in script is modified;
1665: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1726: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1727: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1728: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1745: - SCLS is added;
1746: - DRWS now uses COLS to draw 2D graphics;
1747: - PPAR and SPAR are written. SPAR returns a list that contains the

1749: statistical variable, or "DISABLED" if its type is not one of the type of
1750: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1751: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1752: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1753: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1754: disabled. Arguments of EXTERNAL are case sensitive because the external
1755: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1756: of known external functions but add the new list to the last. { "all" }
1757: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1758: external names of the known functions;
1759: - mkrplso.in is modified.
1760: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1761: - vim syntax file is upgraded;
1762: - a minor mistake is fixed in recherche_instruction_suivante();

1773: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1774: VISIT does not find a name in level 1;
1775: - configure.in script is modified to add a new test (--enable-debug
1776: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1777: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1778: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1779: 'MATRIX' { 2 2 3 } GETR;
1780: - LOGSCALE intrinsic is improved and now, it can be used as
1781: { "main" "auxiliary" X Y } LOGSCALE;
1782: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1783: same than AXES:
1784: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1785: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1786: { { -10 10 } "automatic" } SCALE.
1787: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1788: because it changes only the dimension of the screen. To have a logarithmic
1789: scale, you must use LOGSCALE intrinsic:
1790: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1791: screen on second scale;
1792: - { X X } autoscale and { Y Y } logscale are now invalid;
1793: - *D is added (depth multiplication, for 3D graphics);
1794: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1795: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1796: - a major bug is fixed in GETI instrinsic when it is used with a name
1797: that contains a matrix or a vector (bad upper bounds conditions in
1798: incrementation);
1799: - DISP intrinsic now uses the 33-th flag. When it is not set
1800: (default), a final carriage return is sent to the terminal;
1801: - AXES intrinsic only takes a list that can contains the keywork
1802: "main" or "auxiliary". Before this modification, this keyword was in
1803: the first stack level;
1804: - vim syntax file is upgraded;
1805: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1806: option;
1807: - LAST is now disabled in the main loop of INT intrinsic;
1808: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1809: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1810: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1811: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1812: in 0);
1813: - LAST is disabled in the main loop of DRAW intrinsic;
1814: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1815: evaluation of an equation, the system stack is returned corrupted to the
1816: sequencer;
1817: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1818: of a loop are not integer or real.
1819: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1820: - the compilation stage aborts with an error message when two definitions
1821: have the same name. To improve the compilation() subroutine, I have to
1822: add some tests in gestion_variables.c;
1823: - recherche_type() subroutine ad some other connex subroutines are improved.
1824: Now, some syntax errors about object are caught and do not perform sequencer
1825: hangup;
1826: - readline is upgraded (minor compilation bug with recent gcc);
1827: - Makefile.am's and configure.in scripts are improved.
1828: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1829: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1830: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1831: the boxwidth, 1 by default);
1832: - recherche_type() is rewritten to be faster;
1833: - gsl is upgraded (release 1.3);
1834: - ncurses is upgraded and patched (release 5.3);
1835: - recherche_instruction_suivante() is fixed (string research with included
1836: '"') and rewritten to be faster;

1847: - a minor bug is fixed in evaluation subroutine;
1848: - vim syntax file is improved;
1849: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1850: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1851: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1852: is a quick and dirty workaround...);
1853: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1854: - rplconvert is improved.
1855: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
