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

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

  474: ABORT now works on eComStation;
  475: - sqlite is upgraded to 3.7.2;
  476: - bug is fixed in software interrupts. When both process have different PID,
  477: parent process was not interrupted if it is not group master process. To fix
  478: this bug, SIGINJECT signal is not sent by child process but by control thread
  479: in parent process;
  480: - minor bug is fixed in data injection (POKE) that does not work as expected
  481: when child process is protected by NRPROC.
  482: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
  483: - --enable-sysv-sems is added to configure script to use SystemV semaphores
  484: functions instead of POSIX functions. This function is disabled or forced on
  485: systems that does not provide correct POSIX or SysV semaphores subsystem;
  486: - a dirty but not quick patch is written to workaround broken siginfo
  487: structures. This patch has been successfully tested. It uses a segment of
  488: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
  489: (Unix PID);
  490: - some OpenBSD's hacks are added;

  506: - sqlite is upgraded to 3.7.0.1;
  507: - units is upgraded to 1.88;
  508: - another major bug is fixed in the same variable creation subroutine.
  509: Level 0 and 1 variables adresses were swapped when a global variable masked
  510: a name of RPL/2 routine;
  511: - major bug is fixed in global variable creation subroutine. When a global
  512: variable was created and when a local variable existed with the same name,
  513: computed address of global variable was wrong;
  514: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
  515: is forced in front of all libraries.
  516: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
  517: - BACKTRACE intrinsic is added;
  518: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
  519: when this structure is included in IFERR/THEN/END structure and when an error is
  520: caught;
  521: - major bug is fixed in analyse() subroutine. When evaluation() returned error
  522: in a compiled program, analyse() caught this error twice and randomly aborted
  523: with a segmentation error;
  524: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
  525: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
  526: signals;
  527: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
  528: matrix.
  529: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

  540: linux (false mremap() prototype);
  541: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
  542: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
  543: - all '-' are replaced by '_' in random generator list;
  544: - minor memory leak is fixed in OPEN intrinsic (socket);
  545: - major bug is fixed in IFERR structure. Only occurs in compiled program;
  546: - major bug is fixed in copie_objet() and liberation(). Only concerns
  547: format in FCH (file descriptor) and SCK (socket descriptor);
  548: - debug routines are improved;
  549: - PROCID is added;
  550: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
  551: and to not use swap;
  552: - major bug is fixed in sql support. SQL connections were closed in all chield
  553: process;
  554: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
  555: discovered in Solaris thread safe allocators (libmalloc and libumem) that
  556: are first fit class allocators. Solaris libmtmalloc works better and is
  557: a best fit class allocator but its performance is poor than ptmalloc3
  558: performance;
  559: - major bug is fixed in ROW+ intrinsic (new row was not added where it
  560: should);
  561: - minor bugs are fixed in interruptions.c (semaphores values when error is
  562: caught);
  563: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
  564: created by SPAWN;
  565: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
  566: ATEXIT. If it receives SIGFABORT, it does not;
  567: - ONEXIT is renamed in ATEXIT;
  568: - ONEXIT new intrinsic is added.
  569: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)

  571: This bug only occurs when RPL/2 tries to create a shared or static variable
  572: from an expression;
  573: - major bug is fixed in copie_etat_processus(). A field that contains
  574: information about shared variable was not copied to new processus structure;
  575: - some little memory leaks are fixed in evaluation(), recherche_type() and
  576: sequenceur(). They only occured when syntax error were caught;
  577: - IMPLICIT causes execution error instead system error;
  578: - Hurd support is improved but currently broken because Hurd does not support
  579: SIG_INFO. Work in progress;
  580: - OpenBSD specific support is removed from sources;
  581: - support for Mac OS X and Windows/Cygwin is added.

  676: signals sent to main process were not caught because DAEMON did not replace
  677: old pid by new one;
  678: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression

  721: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
  722: used in onLoading from shared library, USE was pushed on stack as algebraic
  723: expression;
  724: - libiconv is upgraded to 1.13.1;
  725: - gnuplot is upgraded to 4.2.6;
  726: - gsl is upgraded to 1.13.
  727: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
  728: - pipe() is overwritten by a macro to avoid a system error. Communication
  729: between process are done with pipes and these pipes are managed by a
  730: specific asynchrone thread. If a script try to create more threads than
  731: management thread can destroy, you can quickly achieve maximum number of
  732: opened files and pipe() shall return a system error. This macro tries to create
  733: pipes. If pipe() function returns an error, macro waits and retries. If
  734: number of retries is greater than a hardcoded value, macro returns an error;
  735: - major bug (deadlock) is fixed in process and thread management. I hope
  736: this bug shall be the last one;
  737: - major bug is fixed in DET intrinsic (determinant was computed without LU
  738: diagonalization);
  739: - SWAPCNTXT is added;
  740: - minor bug is fixed in Makefile.am (licences rule).
  741: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
  742: - some bugfixes are added in process management;
  743: - all process management is rewritten to avoid usage of defunct process
  744: or thread number;
  745: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
  746: was called before a pending interruption5 (SIGFSTOP), signal handler uses
  747: a freed semaphore and corrupts heap;
  748: - CLRERR is added to erase previous errors;
  749: - ERRN and ERRM return exception message and number;
  750: - major bug is fixed in interruptions.c. All signal are now bufferised
  751: when semaphore_liste_threads is null to avoid deadlock. This bug only
  752: occured when STOP was sent to a dying thread or process (when this thread or
  753: process was running retrait_thread());
  754: - matrix rank is computed before matrix inversion;
  755: - file locks are added to stdin and stdout. stderr is not locked because
  756: all messages written by signal handlers are sent to stderr;
  757: - configure.in script is modified to test gcc version and avoid a bug in
  758: gcc older than 4.4;
  759: - some benchmarks have been done :

  804: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
  805: process termination);
  806: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
  807: its parent);
  808: - a mutex to protect fork() syscall is added;
  809: - all mutexes are unlocked after fork() in DETACH;
  810: - minor bug (double free corruption) is fixed in CLOSE intrinsic;

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

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

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

  898: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
  899: that all programs that worked with old SQL intrinsic can now work with
  900: SQLQUERY. With all new programs, you can open a real connection to databases;
  901: - NRPROC is added. This new intrinsic is used to catch error from child
  902: process. Without NRPROC, any errors returned by child process cause
  903: main process to abort;
  904: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
  905: starts a new process). There are no mutexes in RPL/2 because all spawned process
  906: use specific context. Nevertheless, shared variables and associated mutexes
  907: should be added;
  908: - -D flag and DAEMONIZE intrinsic have been added;
  909: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

  997: work fine;
  998: - '->' is modified to return error when program tries to initialiaze two

 1054: not support real time signals, RPL/2 cannot use multitasking functions;
 1055: - error returned by preprocessor are now catched by RPL/2;
 1056: - -p option is added. With this option, all scripts are compiled before
 1057: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run

 1178: - minor bug is fixed in recherche_type(). Don't forget that space
 1179: are not significant in algebraic expression:
 1180: '12 3+ 12    X' is the same expression than '123+12X';
 1181: - src/Makefile.am is modified to avoid double compilation process;
 1182: - --enable-final-run-path is added to configure.in script;

 1200: functions were case unsensitive when they were evaluated from RPN expressions;
 1201: - HELP function is rewritten to be more friendly (a la OpenVMS);
 1202: - external wrapper (rplplot) is written to force usage of gnuplot provided
 1203: by RPL/2 if it is built during build process. If this build does not exist,
 1204: it tries to launch regular gnuplot;
 1205: - gnuplot is added to source tree to avoid some trouble between preinstalled
 1206: gnuplot and release used by RPL/2. This addition to source tree is
 1207: required by some incompatibility between gnuplot releases;

 1213: not writable;
 1214: - major regression is fixed in SYSEVAL intrinsic due to introduction of
 1215: error scrutation.

 1257: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
 1258: versions of PROTECT and UNPROTECT that only deal with global variables
 1259: (see RCL/SAVE);
 1260: - variable management routines have been rewritten. The new ones are
 1261: uncompatible with the old ones. Before these changes, a local variable
 1262: was exported to a child subroutine, but cannot be modified into this
 1263: child subroutine. Now, a local variable is accessible only in its subroutine;
 1264: - SAVE intrinsic is added to manipulate global variables;

 1585: fine...);
 1586: - NOT is not correctly formatted in formateur.c:
 1587: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
 1588: with a NOTZ function !
 1589: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

 1592: - RPL/2 is tested with efence and valgrind;
 1593: - configure.in script is modified;
 1594: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

 1655: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
 1656: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
 1657: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

 1674: - SCLS is added;
 1675: - DRWS now uses COLS to draw 2D graphics;
 1676: - PPAR and SPAR are written. SPAR returns a list that contains the
 1677: size of the statistical matrix (or "UNAVALAIBLE" if there is any
 1678: statistical variable, or "DISABLED" if its type is not one of the type of
 1679: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
 1680: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
 1681: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
 1682: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
 1683: disabled. Arguments of EXTERNAL are case sensitive because the external
 1684: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
 1685: of known external functions but add the new list to the last. { "all" }
 1686: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
 1687: external names of the known functions;
 1688: - mkrplso.in is modified.
 1689: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
 1690: - vim syntax file is upgraded;
 1691: - a minor mistake is fixed in recherche_instruction_suivante();
 1692: - some minor memory leaks are fixed in recherche_type() function. They only

 1703: VISIT does not find a name in level 1;
 1704: - configure.in script is modified to add a new test (--enable-debug
 1705: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
 1706: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
 1707: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
 1708: 'MATRIX' { 2 2 3 } GETR;
 1709: - LOGSCALE intrinsic is improved and now, it can be used as
 1710: { "main" "auxiliary" X Y } LOGSCALE;
 1711: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
 1712: same than AXES:
 1713: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
 1714: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
 1715: { { -10 10 } "automatic" } SCALE.
 1716: Warning, it is not possible to ask a logarithmic scale with this intrinsic
 1717: because it changes only the dimension of the screen. To have a logarithmic
 1718: scale, you must use LOGSCALE intrinsic:
 1719: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
 1720: screen on second scale;
 1721: - { X X } autoscale and { Y Y } logscale are now invalid;
 1722: - *D is added (depth multiplication, for 3D graphics);
 1723: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
 1724: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
 1725: - a major bug is fixed in GETI instrinsic when it is used with a name
 1726: that contains a matrix or a vector (bad upper bounds conditions in
 1727: incrementation);
 1728: - DISP intrinsic now uses the 33-th flag. When it is not set
 1729: (default), a final carriage return is sent to the terminal;
 1730: - AXES intrinsic only takes a list that can contains the keywork
 1731: "main" or "auxiliary". Before this modification, this keyword was in
 1732: the first stack level;
 1733: - vim syntax file is upgraded;
 1734: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
 1735: option;
 1736: - LAST is now disabled in the main loop of INT intrinsic;
 1737: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
 1738: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
 1739: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
 1740: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
 1741: in 0);
 1742: - LAST is disabled in the main loop of DRAW intrinsic;
 1743: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
 1744: evaluation of an equation, the system stack is returned corrupted to the
 1745: sequencer;
 1746: - the same minor bug is fixed in FOR and START. It only occurs when the limits
 1747: of a loop are not integer or real.
 1748: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

 1756: - Makefile.am's and configure.in scripts are improved.
 1757: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
 1758: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
 1759: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

 1761: - recherche_type() is rewritten to be faster;
 1762: - gsl is upgraded (release 1.3);
 1763: - ncurses is upgraded and patched (release 5.3);
 1764: - recherche_instruction_suivante() is fixed (string research with included
 1765: '"') and rewritten to be faster;

 1776: - a minor bug is fixed in evaluation subroutine;
 1777: - vim syntax file is improved;
 1778: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
 1779: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
 1780: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
 1781: is a quick and dirty workaround...);
 1782: - RETURN intrinsic is modified to fix a trouble in interactive mode;
 1783: - rplconvert is improved.
 1784: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
