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

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

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

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

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

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

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

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

719: script file contains a multibyte character;
720: - IN intrinsic is added;
721: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
722: returned false ;

738: Indeed, conversion between different encodages requires transliteration
739: that is not offered by some iconv utility;
740: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
741: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

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

770: diagonalization);
771: - SWAPCNTXT is added;
772: - minor bug is fixed in Makefile.am (licences rule).
773: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
774: - some bugfixes are added in process management;
775: - all process management is rewritten to avoid usage of defunct process
776: or thread number;

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

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

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

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

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

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

1078: before starting interrupt evaluation;
1079: - -f parameter is added when iconv is called;
1080: - as old file program was bugged, a new option is added to configure script.
1081: When configure is called with --disable-encoding-autodetection, make does not

1153: library is loaded;
1154: - OPEN arguments are changed;
1155: - EXTERNAL now checks availability of external functions;
1156: - number of arguments is verified in analyse_algebrique().
1157: 'SIN(A+X,2)' is now refused because SIN requires only one argument;
1158: - all but lapack symbols are exported from librpl with librpl, f77 or f90
1159: prefix;

1171: - major bug is fixed in tex.h (multiline strings);
1172: - examples subdir is added;
1173: - major bug is fixed in recherche_variable(). When an expression is evaluated
1174: in a function, all variables set in this function must be visible in

1199: - ARCCOS, ARCSIN, ARCTG, ARGCH, ARGSH, ARGTH, CH, SH, TH and TG intrinsics
1200: are removed, because all of these intrinsics have two forms. ARCCOS is
1201: the same than ACOS, TAN=TG, COSH=CH. Please adapt your scripts;
1202: - gnuplot compilation does not have to be done when disable-gnuplot is set;

1210: - minor bug is fixed in recherche_type(). Don't forget that space
1211: are not significant in algebraic expression:
1212: '12 3+ 12 X' is the same expression than '123+12X';
1213: - src/Makefile.am is modified to avoid double compilation process;
1214: - --enable-final-run-path is added to configure.in script;

1232: functions were case unsensitive when they were evaluated from RPN expressions;
1233: - HELP function is rewritten to be more friendly (a la OpenVMS);
1234: - external wrapper (rplplot) is written to force usage of gnuplot provided
1235: by RPL/2 if it is built during build process. If this build does not exist,
1236: it tries to launch regular gnuplot;
1237: - gnuplot is added to source tree to avoid some trouble between preinstalled
1238: gnuplot and release used by RPL/2. This addition to source tree is
1239: required by some incompatibility between gnuplot releases;

1245: not writable;
1246: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1247: error scrutation.

1258: - major bug is fixed in impression_tex(). PRINT did not work due to a bug
1259: introduced by multitasking code;
1260: - SORT can now use name as its argument.
1261: * Sun Jan 21 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.00pre8t (RPL/2)
1262: - Variable management has been rewritten and some tests have been done. Now,
1263: it is possible to execute:
1264:
1265: #!/usr/local/bin/rpl -sc
1266:
1267: TEST
1268: <<
1269: 1 1000 start VAR_S VAR_S2 next
1270: >>
1271:
1272: VAR_S
1273: <<
1274: static 3 -> C << C disp 'C' incr if C 10 > then 'C' volatile end >>
1275: >>

1287: With STATIC, next variables created by '->' are static;
1288: - PROTECT and UNPROTECT are added to protect variables against write
1289: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1290: versions of PROTECT and UNPROTECT that only deal with global variables
1291: (see RCL/SAVE);
1292: - variable management routines have been rewritten. The new ones are
1293: uncompatible with the old ones. Before these changes, a local variable
1294: was exported to a child subroutine, but cannot be modified into this
1295: child subroutine. Now, a local variable is accessible only in its subroutine;
1296: - SAVE intrinsic is added to manipulate global variables;

1617: fine...);
1618: - NOT is not correctly formatted in formateur.c:
1619: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1620: with a NOTZ function !
1621: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1624: - RPL/2 is tested with efence and valgrind;
1625: - configure.in script is modified;
1626: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1687: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1688: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1689: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1706: - SCLS is added;
1707: - DRWS now uses COLS to draw 2D graphics;
1708: - PPAR and SPAR are written. SPAR returns a list that contains the
1709: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1710: statistical variable, or "DISABLED" if its type is not one of the type of
1711: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1712: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1713: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1714: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1715: disabled. Arguments of EXTERNAL are case sensitive because the external
1716: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1717: of known external functions but add the new list to the last. { "all" }
1718: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1719: external names of the known functions;
1720: - mkrplso.in is modified.
1721: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1722: - vim syntax file is upgraded;
1723: - a minor mistake is fixed in recherche_instruction_suivante();
1724: - some minor memory leaks are fixed in recherche_type() function. They only

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

1808: - a minor bug is fixed in evaluation subroutine;
1809: - vim syntax file is improved;
1810: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1811: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1812: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1813: is a quick and dirty workaround...);
1814: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1815: - rplconvert is improved.

1881: found by configure are used in rpltypes.h (rplconfig.h is written by configure);
1882: - rdynamic flag is added in src/Makefile.am. This flag is used in the first

1897: deleted too!;
1898: - configure script is improved (and it seems to be good ;-) );

1914: that the RPL/2 seqencer must stop and must give a prompt. This
1915: signal is an asynchonous "HALT" command;
1916: - SIGINT (CTRL+C) variables stack corruption is fixed;
1917: - IFERR seems to be fixed (in equation evaluation routine);
1918: - Memory leak is fixed (ADR object type);

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