341: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
342: - major bug is fixed in STD format (1E7 sq prints 1);
343: - major bug is fixed in READ intrinsic (socket). This bug was introduced
344: by a new feature in glibc.
345: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
346: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
347: "ALL" IMPLICIT when it runs in interactive mode;
348: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
349: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
350: to use SAVE to manipulate global variables;
351: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
352: subroutines;
353: - fix major memory access violation in evaluation subroutine. Only occurs
354: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
355: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
356: when X was a vector or a table.

1.52 bertrand 386: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
387: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
388: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
389: corruption. As internal memory management have been improved, a best fit
390: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 391: - gnuplot is upgraded to 4.4.1;
392: - deadlock is fixed in signal handlers: same mutex was used in standard
393: subroutines (without protected sections by sigprocmask() or pthread_sigmask())

396: that has to be evaluated by ->NUM;
1.49 bertrand 397: - rplfile build process is modify to be sure that rplfile is not modified
398: after rpl build stage (to be sure that rplfile checksum is not modified after

403: ABORT now works on eComStation;
404: - sqlite is upgraded to 3.7.2;
405: - bug is fixed in software interrupts. When both process have different PID,
406: parent process was not interrupted if it is not group master process. To fix
407: this bug, SIGINJECT signal is not sent by child process but by control thread
408: in parent process;
1.46 bertrand 409: - minor bug is fixed in data injection (POKE) that does not work as expected
410: when child process is protected by NRPROC.

1.43 bertrand 412: - --enable-sysv-sems is added to configure script to use SystemV semaphores
413: functions instead of POSIX functions. This function is disabled or forced on
414: systems that does not provide correct POSIX or SysV semaphores subsystem;
415: - a dirty but not quick patch is written to workaround broken siginfo
416: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 417: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 418: (Unix PID);
1.41 bertrand 419: - some OpenBSD's hacks are added;

438: Level 0 and 1 variables adresses were swapped when a global variable masked
439: a name of RPL/2 routine;
1.35 bertrand 440: - major bug is fixed in global variable creation subroutine. When a global
441: variable was created and when a local variable existed with the same name,
442: computed address of global variable was wrong;
443: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
444: is forced in front of all libraries.

446: - BACKTRACE intrinsic is added;
447: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
448: when this structure is included in IFERR/THEN/END structure and when an error is
449: caught;
450: - major bug is fixed in analyse() subroutine. When evaluation() returned error
451: in a compiled program, analyse() caught this error twice and randomly aborted
452: with a segmentation error;
453: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
454: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
455: signals;
456: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
457: matrix.

1.26 bertrand 481: - major bug is fixed in sql support. SQL connections were closed in all chield
482: process;
483: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
484: discovered in Solaris thread safe allocators (libmalloc and libumem) that

491: caught);
492: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
493: created by SPAWN;

503: information about shared variable was not copied to new processus structure;
1.19 bertrand 504: - some little memory leaks are fixed in evaluation(), recherche_type() and
505: sequenceur(). They only occured when syntax error were caught;
506: - IMPLICIT causes execution error instead system error;

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

618: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
619: returned false ;
620: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
621: programs;
622: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
623: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

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

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

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

672: - all process management is rewritten to avoid usage of defunct process
673: or thread number;
674: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
675: was called before a pending interruption5 (SIGFSTOP), signal handler uses
676: a freed semaphore and corrupts heap;
677: - CLRERR is added to erase previous errors;
678: - ERRN and ERRM return exception message and number;
679: - major bug is fixed in interruptions.c. All signal are now bufferised
680: when semaphore_liste_threads is null to avoid deadlock. This bug only
681: occured when STOP was sent to a dying thread or process (when this thread or

732: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
733: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
734: process termination);
735: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
736: its parent);
737: - a mutex to protect fork() syscall is added;

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

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

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

827: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
828: that all programs that worked with old SQL intrinsic can now work with
829: SQLQUERY. With all new programs, you can open a real connection to databases;
830: - NRPROC is added. This new intrinsic is used to catch error from child
831: process. Without NRPROC, any errors returned by child process cause
832: main process to abort;
833: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
834: starts a new process). There are no mutexes in RPL/2 because all spawned process
835: use specific context. Nevertheless, shared variables and associated mutexes
836: should be added;

977: - as old file program was bugged, a new option is added to configure script.
978: When configure is called with --disable-encoding-autodetection, make does not
979: try to detect source encoding. Please, do not use if RPL/2 can be built
980: without this option !
981: - new garbage collector (and more efficient) is written;

1131: - external wrapper (rplplot) is written to force usage of gnuplot provided
1132: by RPL/2 if it is built during build process. If this build does not exist,
1133: it tries to launch regular gnuplot;
1134: - gnuplot is added to source tree to avoid some trouble between preinstalled
1135: gnuplot and release used by RPL/2. This addition to source tree is

1189: - variable management routines have been rewritten. The new ones are
1190: uncompatible with the old ones. Before these changes, a local variable
1191: was exported to a child subroutine, but cannot be modified into this
1192: child subroutine. Now, a local variable is accessible only in its subroutine;
1193: - SAVE intrinsic is added to manipulate global variables;

1514: fine...);
1515: - NOT is not correctly formatted in formateur.c:
1516: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1517: with a NOTZ function !
1518: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1521: - RPL/2 is tested with efence and valgrind;
1522: - configure.in script is modified;
1523: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1584: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1585: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1586: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1603: - SCLS is added;
1604: - DRWS now uses COLS to draw 2D graphics;
1605: - PPAR and SPAR are written. SPAR returns a list that contains the
1606: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1607: statistical variable, or "DISABLED" if its type is not one of the type of
1608: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1609: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1610: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1611: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1612: disabled. Arguments of EXTERNAL are case sensitive because the external
1613: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1614: of known external functions but add the new list to the last. { "all" }
1615: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1616: external names of the known functions;
1617: - mkrplso.in is modified.
1618: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1619: - vim syntax file is upgraded;
1620: - a minor mistake is fixed in recherche_instruction_suivante();

1630: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1631: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1632: VISIT does not find a name in level 1;
1633: - configure.in script is modified to add a new test (--enable-debug
1634: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1635: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1636: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1637: 'MATRIX' { 2 2 3 } GETR;
1638: - LOGSCALE intrinsic is improved and now, it can be used as
1639: { "main" "auxiliary" X Y } LOGSCALE;
1640: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1641: same than AXES:
1642: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1643: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1644: { { -10 10 } "automatic" } SCALE.
1645: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1646: because it changes only the dimension of the screen. To have a logarithmic
1647: scale, you must use LOGSCALE intrinsic:
1648: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1649: screen on second scale;
1650: - { X X } autoscale and { Y Y } logscale are now invalid;
1651: - *D is added (depth multiplication, for 3D graphics);
1652: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1653: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1654: - a major bug is fixed in GETI instrinsic when it is used with a name
1655: that contains a matrix or a vector (bad upper bounds conditions in
1656: incrementation);
1657: - DISP intrinsic now uses the 33-th flag. When it is not set
1658: (default), a final carriage return is sent to the terminal;
1659: - AXES intrinsic only takes a list that can contains the keywork
1660: "main" or "auxiliary". Before this modification, this keyword was in
1661: the first stack level;
1662: - vim syntax file is upgraded;
1663: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1664: option;
1665: - LAST is now disabled in the main loop of INT intrinsic;
1666: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1667: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1668: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1669: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1670: in 0);
1671: - LAST is disabled in the main loop of DRAW intrinsic;
1672: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1673: evaluation of an equation, the system stack is returned corrupted to the
1674: sequencer;
1675: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1676: of a loop are not integer or real.
1677: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1678: - the compilation stage aborts with an error message when two definitions
1679: have the same name. To improve the compilation() subroutine, I have to
1680: add some tests in gestion_variables.c;
1681: - recherche_type() subroutine ad some other connex subroutines are improved.
1682: Now, some syntax errors about object are caught and do not perform sequencer
1683: hangup;
1684: - readline is upgraded (minor compilation bug with recent gcc);
1685: - Makefile.am's and configure.in scripts are improved.
1686: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1687: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1688: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1689: the boxwidth, 1 by default);
1690: - recherche_type() is rewritten to be faster;
1691: - gsl is upgraded (release 1.3);
1692: - ncurses is upgraded and patched (release 5.3);
1693: - recherche_instruction_suivante() is fixed (string research with included
1694: '"') and rewritten to be faster;
1695: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1696: segfault.

1708: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1709: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1710: is a quick and dirty workaround...);
1711: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1712: - rplconvert is improved.

1823: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1824: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1825:
1826: Newton:[~/rpl/rpl] > time make install
1827: ...
1828: real 338m39.623s
