426: - major bug is fixed in STD format (1E7 sq prints 1);
427: - major bug is fixed in READ intrinsic (socket). This bug was introduced
428: by a new feature in glibc.
429: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
430: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
431: "ALL" IMPLICIT when it runs in interactive mode;
432: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
433: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
434: to use SAVE to manipulate global variables;
435: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
436: subroutines;
437: - fix major memory access violation in evaluation subroutine. Only occurs
438: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
439: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
440: when X was a vector or a table.

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

491: this bug, SIGINJECT signal is not sent by child process but by control thread
492: in parent process;
493: - minor bug is fixed in data injection (POKE) that does not work as expected
494: when child process is protected by NRPROC.
495: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
496: - --enable-sysv-sems is added to configure script to use SystemV semaphores
497: functions instead of POSIX functions. This function is disabled or forced on
498: systems that does not provide correct POSIX or SysV semaphores subsystem;
499: - a dirty but not quick patch is written to workaround broken siginfo
500: structures. This patch has been successfully tested. It uses a segment of
501: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
502: (Unix PID);
503: - some OpenBSD's hacks are added;
504: - broken siginfo->si_pid field is now checked by configure script;

522: Level 0 and 1 variables adresses were swapped when a global variable masked
523: a name of RPL/2 routine;
524: - major bug is fixed in global variable creation subroutine. When a global
525: variable was created and when a local variable existed with the same name,
526: computed address of global variable was wrong;
527: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
528: is forced in front of all libraries.
529: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
530: - BACKTRACE intrinsic is added;
531: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
532: when this structure is included in IFERR/THEN/END structure and when an error is
533: caught;
534: - major bug is fixed in analyse() subroutine. When evaluation() returned error
535: in a compiled program, analyse() caught this error twice and randomly aborted
536: with a segmentation error;
537: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
538: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
539: signals;
540: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
541: matrix.

560: format in FCH (file descriptor) and SCK (socket descriptor);
561: - debug routines are improved;
562: - PROCID is added;
563: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
564: and to not use swap;
565: - major bug is fixed in sql support. SQL connections were closed in all chield
566: process;
567: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
568: discovered in Solaris thread safe allocators (libmalloc and libumem) that
569: are first fit class allocators. Solaris libmtmalloc works better and is
570: a best fit class allocator but its performance is poor than ptmalloc3
571: performance;
572: - major bug is fixed in ROW+ intrinsic (new row was not added where it
573: should);
574: - minor bugs are fixed in interruptions.c (semaphores values when error is
575: caught);
576: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
577: created by SPAWN;

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

646: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
647: each execution (md5 and sha1 sums) to enhance security. If one of these tools
648: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
649: on a non recoverable system error;
650: - openssl and sqlite3 libraries are added;
651: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
652: variable indicates RPL/2 root directory. If it is not set, root path
653: is given by configure script (d_exec_path);
654: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

687: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
688: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
689: signals sent to main process were not caught because DAEMON did not replace
690: old pid by new one;
691: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
692: evaluation when an error is reported from a subroutine in another subroutine.
693: For example, error was not caught in following program when it is executed with
694: -p option :

711: - major bug is fixed in -A command line option (NULL character is missing);
712: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
713: made by blocks (1024 bytes). When an incomplete multibyte sequence is
714: encountered at end of block, subroutine aborts with an execution error;
715: - major bug is fixed in OPEN (TCP/IPv4 sockets).
716: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
717: - DISP now locks stdout;
718: - rpliconv is added to replace standard iconv provided by operating system.
719: Indeed, conversion between different encodages requires transliteration
720: that is not offered by some iconv utility;
721: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
722: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

735: used in onLoading from shared library, USE was pushed on stack as algebraic
736: expression;
737: - libiconv is upgraded to 1.13.1;
738: - gnuplot is upgraded to 4.2.6;
739: - gsl is upgraded to 1.13.

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

756: - all process management is rewritten to avoid usage of defunct process
757: or thread number;
758: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
759: was called before a pending interruption5 (SIGFSTOP), signal handler uses
760: a freed semaphore and corrupts heap;
761: - CLRERR is added to erase previous errors;
762: - ERRN and ERRM return exception message and number;
763: - major bug is fixed in interruptions.c. All signal are now bufferised
764: when semaphore_liste_threads is null to avoid deadlock. This bug only
765: occured when STOP was sent to a dying thread or process (when this thread or
766: process was running retrait_thread());
767: - matrix rank is computed before matrix inversion;

844: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
845: process is killed;
846: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
847: know typeof() intrinsic function. This function is not standard but exists
848: under Sun Studio, gcc, and maybe some others compilers. If this function does
849: not exist on your compiler, you can change its definition by old one in
850: src/rpl.h;

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

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

913: SQLQUERY. With all new programs, you can open a real connection to databases;
914: - NRPROC is added. This new intrinsic is used to catch error from child
915: process. Without NRPROC, any errors returned by child process cause
916: main process to abort;
917: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
918: starts a new process). There are no mutexes in RPL/2 because all spawned process
919: use specific context. Nevertheless, shared variables and associated mutexes
920: should be added;

1214: - HELP function is rewritten to be more friendly (a la OpenVMS);
1215: - external wrapper (rplplot) is written to force usage of gnuplot provided
1216: by RPL/2 if it is built during build process. If this build does not exist,
1217: it tries to launch regular gnuplot;
1218: - gnuplot is added to source tree to avoid some trouble between preinstalled
1219: gnuplot and release used by RPL/2. This addition to source tree is

1273: - variable management routines have been rewritten. The new ones are
1274: uncompatible with the old ones. Before these changes, a local variable
1275: was exported to a child subroutine, but cannot be modified into this
1276: child subroutine. Now, a local variable is accessible only in its subroutine;
1277: - SAVE intrinsic is added to manipulate global variables;

1598: fine...);
1599: - NOT is not correctly formatted in formateur.c:
1600: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1601: with a NOTZ function !
1602: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1603: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1605: - RPL/2 is tested with efence and valgrind;
1606: - configure.in script is modified;
1607: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1668: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1669: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1670: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1687: - SCLS is added;
1688: - DRWS now uses COLS to draw 2D graphics;
1689: - PPAR and SPAR are written. SPAR returns a list that contains the
1690: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1691: statistical variable, or "DISABLED" if its type is not one of the type of
1692: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1693: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1694: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1695: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1696: disabled. Arguments of EXTERNAL are case sensitive because the external
1697: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1698: of known external functions but add the new list to the last. { "all" }
1699: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1700: external names of the known functions;
1701: - mkrplso.in is modified.
1702: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1703: - vim syntax file is upgraded;
1704: - a minor mistake is fixed in recherche_instruction_suivante();
1705: - some minor memory leaks are fixed in recherche_type() function. They only

1714: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1715: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1716: VISIT does not find a name in level 1;
1717: - configure.in script is modified to add a new test (--enable-debug
1718: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1719: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1720: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1721: 'MATRIX' { 2 2 3 } GETR;
1722: - LOGSCALE intrinsic is improved and now, it can be used as
1723: { "main" "auxiliary" X Y } LOGSCALE;
1724: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1725: same than AXES:
1726: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1727: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1728: { { -10 10 } "automatic" } SCALE.
1729: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1730: because it changes only the dimension of the screen. To have a logarithmic
1731: scale, you must use LOGSCALE intrinsic:
1732: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1733: screen on second scale;
1734: - { X X } autoscale and { Y Y } logscale are now invalid;
1735: - *D is added (depth multiplication, for 3D graphics);
1736: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1737: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1738: - a major bug is fixed in GETI instrinsic when it is used with a name
1739: that contains a matrix or a vector (bad upper bounds conditions in
1740: incrementation);
1741: - DISP intrinsic now uses the 33-th flag. When it is not set
1742: (default), a final carriage return is sent to the terminal;
1743: - AXES intrinsic only takes a list that can contains the keywork
1744: "main" or "auxiliary". Before this modification, this keyword was in
1745: the first stack level;
1746: - vim syntax file is upgraded;
1747: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1748: option;
1749: - LAST is now disabled in the main loop of INT intrinsic;
1750: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1751: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1752: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1753: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1754: in 0);
1755: - LAST is disabled in the main loop of DRAW intrinsic;
1756: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1757: evaluation of an equation, the system stack is returned corrupted to the
1758: sequencer;
1759: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1760: of a loop are not integer or real.
1761: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1762: - the compilation stage aborts with an error message when two definitions
1763: have the same name. To improve the compilation() subroutine, I have to
1764: add some tests in gestion_variables.c;
1765: - recherche_type() subroutine ad some other connex subroutines are improved.
1766: Now, some syntax errors about object are caught and do not perform sequencer
1767: hangup;
1768: - readline is upgraded (minor compilation bug with recent gcc);
1769: - Makefile.am's and configure.in scripts are improved.
1770: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1771: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1772: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1773: the boxwidth, 1 by default);
1774: - recherche_type() is rewritten to be faster;
1775: - gsl is upgraded (release 1.3);
1776: - ncurses is upgraded and patched (release 5.3);
1777: - recherche_instruction_suivante() is fixed (string research with included
1778: '"') and rewritten to be faster;
1779: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1780: segfault.

1790: - vim syntax file is improved;
1791: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1792: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1793: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1794: is a quick and dirty workaround...);
1795: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1796: - rplconvert is improved.

1878: deleted too!;
1879: - configure script is improved (and it seems to be good ;-) );

1897: - SIGINT (CTRL+C) variables stack corruption is fixed;
1898: - IFERR seems to be fixed (in equation evaluation routine);

1907: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1908: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1909:
1910: Newton:[~/rpl/rpl] > time make install
1911: ...
1912: real 338m39.623s
1913: user 324m32.290s
