442: - major bug is fixed in STD format (1E7 sq prints 1);
443: - major bug is fixed in READ intrinsic (socket). This bug was introduced
444: by a new feature in glibc.
445: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
446: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
447: "ALL" IMPLICIT when it runs in interactive mode;
448: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
449: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
450: to use SAVE to manipulate global variables;
451: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
452: subroutines;
453: - fix major memory access violation in evaluation subroutine. Only occurs
454: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
455: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
456: when X was a vector or a table.
457: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

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

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

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

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

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

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

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

716: script file contains a multibyte character;
717: - IN intrinsic is added;
718: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME

732: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
733: - DISP now locks stdout;
734: - rpliconv is added to replace standard iconv provided by operating system.
735: Indeed, conversion between different encodages requires transliteration
736: that is not offered by some iconv utility;
737: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
738: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

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

770: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
771: - some bugfixes are added in process management;
772: - all process management is rewritten to avoid usage of defunct process
773: or thread number;

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

782: process was running retrait_thread());
783: - matrix rank is computed before matrix inversion;
784: - file locks are added to stdin and stdout. stderr is not locked because
785: all messages written by signal handlers are sent to stderr;
786: - configure.in script is modified to test gcc version and avoid a bug in
787: gcc older than 4.4;
788: - some benchmarks have been done :

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

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

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

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

1075: before starting interrupt evaluation;
1076: - -f parameter is added when iconv is called;
1077: - as old file program was bugged, a new option is added to configure script.
1078: When configure is called with --disable-encoding-autodetection, make does not

1230: - HELP function is rewritten to be more friendly (a la OpenVMS);
1231: - external wrapper (rplplot) is written to force usage of gnuplot provided
1232: by RPL/2 if it is built during build process. If this build does not exist,
1233: it tries to launch regular gnuplot;
1234: - gnuplot is added to source tree to avoid some trouble between preinstalled
1235: gnuplot and release used by RPL/2. This addition to source tree is

1286: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1287: versions of PROTECT and UNPROTECT that only deal with global variables
1288: (see RCL/SAVE);
1289: - variable management routines have been rewritten. The new ones are
1290: uncompatible with the old ones. Before these changes, a local variable
1291: was exported to a child subroutine, but cannot be modified into this
1292: child subroutine. Now, a local variable is accessible only in its subroutine;

1614: fine...);
1615: - NOT is not correctly formatted in formateur.c:
1616: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1617: with a NOTZ function !
1618: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1703: - SCLS is added;
1704: - DRWS now uses COLS to draw 2D graphics;
1705: - PPAR and SPAR are written. SPAR returns a list that contains the
1706: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1707: statistical variable, or "DISABLED" if its type is not one of the type of
1708: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1709: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1710: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1711: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1712: disabled. Arguments of EXTERNAL are case sensitive because the external
1713: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1714: of known external functions but add the new list to the last. { "all" }
1715: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1716: external names of the known functions;
1717: - mkrplso.in is modified.
1718: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1732: VISIT does not find a name in level 1;
1733: - configure.in script is modified to add a new test (--enable-debug
1734: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1735: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1736: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1737: 'MATRIX' { 2 2 3 } GETR;
1738: - LOGSCALE intrinsic is improved and now, it can be used as
1739: { "main" "auxiliary" X Y } LOGSCALE;
1740: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1741: same than AXES:
1742: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1743: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1744: { { -10 10 } "automatic" } SCALE.
1745: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1746: because it changes only the dimension of the screen. To have a logarithmic
1747: scale, you must use LOGSCALE intrinsic:
1748: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1749: screen on second scale;
1750: - { X X } autoscale and { Y Y } logscale are now invalid;
1751: - *D is added (depth multiplication, for 3D graphics);
1752: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1753: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1754: - a major bug is fixed in GETI instrinsic when it is used with a name
1755: that contains a matrix or a vector (bad upper bounds conditions in
1756: incrementation);
1757: - DISP intrinsic now uses the 33-th flag. When it is not set
1758: (default), a final carriage return is sent to the terminal;
1759: - AXES intrinsic only takes a list that can contains the keywork
1760: "main" or "auxiliary". Before this modification, this keyword was in
1761: the first stack level;
1762: - vim syntax file is upgraded;
1763: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1764: option;
1765: - LAST is now disabled in the main loop of INT intrinsic;
1766: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1767: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1768: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1769: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1770: in 0);
1771: - LAST is disabled in the main loop of DRAW intrinsic;
1772: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1773: evaluation of an equation, the system stack is returned corrupted to the
1774: sequencer;
1775: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1776: of a loop are not integer or real.
1777: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1778: - the compilation stage aborts with an error message when two definitions
1779: have the same name. To improve the compilation() subroutine, I have to
1780: add some tests in gestion_variables.c;
1781: - recherche_type() subroutine ad some other connex subroutines are improved.
1782: Now, some syntax errors about object are caught and do not perform sequencer
1783: hangup;
1784: - readline is upgraded (minor compilation bug with recent gcc);
1785: - Makefile.am's and configure.in scripts are improved.
1786: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1787: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1788: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1789: the boxwidth, 1 by default);
1790: - recherche_type() is rewritten to be faster;
1791: - gsl is upgraded (release 1.3);
1792: - ncurses is upgraded and patched (release 5.3);
1793: - recherche_instruction_suivante() is fixed (string research with included
1794: '"') and rewritten to be faster;

1808: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1809: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1810: is a quick and dirty workaround...);
1811: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1812: - rplconvert is improved.

1870: 'X' 0 + and 0 'X' + return 'X';
1871: 'X' 0 - returns 'X';
1872: 'X' 1 * and 1 'X' * return 'X';

1878: found by configure are used in rpltypes.h (rplconfig.h is written by configure);
1879: - rdynamic flag is added in src/Makefile.am. This flag is used in the first
1880: makefile, but forgotten in the new process;
1881: - Flag 31 is tested before saving any arguments in bibliotheques_externes.c;
1882: - POS can now be used on lists;

1894: deleted too!;
1895: - configure script is improved (and it seems to be good ;-) );
1896: - An --disable-experimental flag is added to the configure script. Thus, even
1897: if you compile a beta release, you can compile a stable RPL/2;
1898: - new syntax and ftplugin written for vim 6.0.

1911: that the RPL/2 seqencer must stop and must give a prompt. This
1912: signal is an asynchonous "HALT" command;
1913: - SIGINT (CTRL+C) variables stack corruption is fixed;
1914: - IFERR seems to be fixed (in equation evaluation routine);
1915: - Memory leak is fixed (ADR object type);

1922: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1923: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1924: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1925:
1926: Newton:[~/rpl/rpl] > time make install
1927: ...
1928: real 338m39.623s
1929: user 324m32.290s
1930: sys 10m47.380s
1931: Newton:[~/rpl/rpl] >
1932:
1933: I don't know if you will compile this language on old worstations, but
1934: it is usable ;-) ;
1935: - SYSEVAL is improved. An external program can be called without any shell.
