1.167 bertrand 14: - ATEXIT registered procedure is now executed even if program is stopped by
15: SIGINT;
1.165 bertrand 16: - minor bug is fixed in TOKENIZE intrinsic instruction. TOKENIZE did not work on
17: a copy of input string;
1.164 bertrand 18: - major bug (segfault) is fixed in liste_variables(). It only occurs
19: when this function is called with shared variables;

242: by a new feature in glibc.
243: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
244: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
245: "ALL" IMPLICIT when it runs in interactive mode;
246: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
247: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
248: to use SAVE to manipulate global variables;
249: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
250: subroutines;
251: - fix major memory access violation in evaluation subroutine. Only occurs
252: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
253: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
254: when X was a vector or a table.

1.52 bertrand 284: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
285: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
286: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
287: corruption. As internal memory management have been improved, a best fit
288: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 289: - gnuplot is upgraded to 4.4.1;
290: - deadlock is fixed in signal handlers: same mutex was used in standard
291: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
292: and signal handlers. A new signal handler specific mutex is added;
293: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
294: that has to be evaluated by ->NUM;
1.49 bertrand 295: - rplfile build process is modify to be sure that rplfile is not modified
296: after rpl build stage (to be sure that rplfile checksum is not modified after

301: ABORT now works on eComStation;
302: - sqlite is upgraded to 3.7.2;
303: - bug is fixed in software interrupts. When both process have different PID,
304: parent process was not interrupted if it is not group master process. To fix
305: this bug, SIGINJECT signal is not sent by child process but by control thread
306: in parent process;
1.46 bertrand 307: - minor bug is fixed in data injection (POKE) that does not work as expected
308: when child process is protected by NRPROC.

1.43 bertrand 310: - --enable-sysv-sems is added to configure script to use SystemV semaphores
311: functions instead of POSIX functions. This function is disabled or forced on
312: systems that does not provide correct POSIX or SysV semaphores subsystem;
313: - a dirty but not quick patch is written to workaround broken siginfo
314: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 315: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 316: (Unix PID);
1.41 bertrand 317: - some OpenBSD's hacks are added;

339: variable was created and when a local variable existed with the same name,
340: computed address of global variable was wrong;
341: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
342: is forced in front of all libraries.

502: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
503: signals sent to main process were not caught because DAEMON did not replace
504: old pid by new one;
505: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
506: evaluation when an error is reported from a subroutine in another subroutine.
507: For example, error was not caught in following program when it is executed with

514: script file contains a multibyte character;
515: - IN intrinsic is added;
516: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
517: returned false ;
518: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
519: programs;
520: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
521: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

539: locales;
540: - '"' can now be used in strings ("\"");
541: - iconv is called with -c in preprocessor stage. It is done to write

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

573: was called before a pending interruption5 (SIGFSTOP), signal handler uses
574: a freed semaphore and corrupts heap;
575: - CLRERR is added to erase previous errors;
576: - ERRN and ERRM return exception message and number;
577: - major bug is fixed in interruptions.c. All signal are now bufferised
578: when semaphore_liste_threads is null to avoid deadlock. This bug only
579: occured when STOP was sent to a dying thread or process (when this thread or
580: process was running retrait_thread());
581: - matrix rank is computed before matrix inversion;

708: to a file, stdin is redirected to /dev/null when control process is killed;
709: - a mutex is added to each object (before this modification,
710: RPL/2 used a global mutex and performances in multithreaded programs were very
711: poor.);
712: - ALARM is now interruptible;
713: - both PUT and PUTI intrinsics are improved and do not copy list and table
714: when nombre_occurrences == 1;

726: that all programs that worked with old SQL intrinsic can now work with
727: SQLQUERY. With all new programs, you can open a real connection to databases;
728: - NRPROC is added. This new intrinsic is used to catch error from child
729: process. Without NRPROC, any errors returned by child process cause
730: main process to abort;
731: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
732: starts a new process). There are no mutexes in RPL/2 because all spawned process
733: use specific context. Nevertheless, shared variables and associated mutexes
734: should be added;

875: - as old file program was bugged, a new option is added to configure script.
876: When configure is called with --disable-encoding-autodetection, make does not
877: try to detect source encoding. Please, do not use if RPL/2 can be built
878: without this option !
879: - new garbage collector (and more efficient) is written;
880: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
881: not support real time signals, RPL/2 cannot use multitasking functions;

883: - -p option is added. With this option, all scripts are compiled before
884: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
885: 40% faster;
886: - read and write operations in pipe() are rewritten to be sure that such
887: operations are atomic;

1006: are not significant in algebraic expression:
1007: '12 3+ 12 X' is the same expression than '123+12X';
1008: - src/Makefile.am is modified to avoid double compilation process;
1009: - --enable-final-run-path is added to configure.in script;

1013: - MEM does not report static variable sizes;
1014: - minor bug is fixed in HELP intrinsic. When the last instruction was not
1015: known, HELP function was pushed in operational stack. HELP did not work

1028: - HELP function is rewritten to be more friendly (a la OpenVMS);
1029: - external wrapper (rplplot) is written to force usage of gnuplot provided
1030: by RPL/2 if it is built during build process. If this build does not exist,
1031: it tries to launch regular gnuplot;
1032: - gnuplot is added to source tree to avoid some trouble between preinstalled
1033: gnuplot and release used by RPL/2. This addition to source tree is
1034: required by some incompatibility between gnuplot releases;
1035: - Lapack is upgraded to 3.1.1 release;
1036: - GSL is upgraded to 1.9 revision;
1037: - RPL_TMP_PATH env variable is added to specify the path of tempfiles. If

1040: not writable;
1041: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1042: error scrutation.

1069: static 3 -> C << C disp 'C' incr if C 10 > then 'C' volatile end >>
1070: >>
1071:
1072: VAR_S2
1073: <<
1074: static 3 -> C << C disp 'C' decr >>
1075: >>
1076:
1077: - configure.in script is added in lapack subtree;
1078: - VARS is modified to display variables status (LOCKED/UNLOCKED and
1079: STATIC/VOLATILE/PARAMETER/VARIABLE);
1080: - STATIC and VOLATILE intrinsics are added to specify static variables. A
1081: static variable can be transformed into volatile with VOLATILE.
1082: With STATIC, next variables created by '->' are static;
1083: - PROTECT and UNPROTECT are added to protect variables against write
1084: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1085: versions of PROTECT and UNPROTECT that only deal with global variables
1086: (see RCL/SAVE);
1087: - variable management routines have been rewritten. The new ones are
1088: uncompatible with the old ones. Before these changes, a local variable
1089: was exported to a child subroutine, but cannot be modified into this
1090: child subroutine. Now, a local variable is accessible only in its subroutine;
1091: - SAVE intrinsic is added to manipulate global variables;
1092: - SUSPEND is written. RPL/2 waits for a SIGCONT signal;
1093: - SORT, COL->, ->COL, ROW->, ROW-> intrinsics are written;
1094: - Makefile.am are improved;
1095: - minor bug is fixed in ->list and ->array. Without any argument, these

1468: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1469: - SLICESCALE intrinsic is added. Its syntax is
1470: { "automatic" nb_of_levels }
1471: { "discrete" l1 l2 l3 ... }
1472: { "incremental" start incr }
1473: { "incremental" start incr end }
1474: { "automatic" } (default);
1475: - a minor bug (in last stack) is fixed in AXES intrinsic
1476: - flag 52 is used to automatically update graphics;
1477: - man pages are updated;
1478: - evaluation() is modified to perform evaluation of expressions that contain
1479: '=';
1480: - a minor bug is fixed in AXES intrinsic;
1481: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1482: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1483: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1484: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1485: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1487: - C and H source files now include vim parameters;
1488: - vim syntax file is modified to include new intrinsics;
1489: - static archive is modified to include all required libraries needed by

1492: - '=' is added and tested;
1493: - XCOL and YCOL are added;
1494: - a minor bug in analyse_syntaxique() is fixed;
1495: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1496: structure. ELSE is modified to return an error when ELSE appears in
1497: an ELSE/END structure;
1498: - a major bug is fixed in CYCLE;
1499: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the

1501: - SCLS is added;
1502: - DRWS now uses COLS to draw 2D graphics;
1503: - PPAR and SPAR are written. SPAR returns a list that contains the
1504: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1505: statistical variable, or "DISABLED" if its type is not one of the type of
1506: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1507: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1508: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1509: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1510: disabled. Arguments of EXTERNAL are case sensitive because the external
1511: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1512: of known external functions but add the new list to the last. { "all" }
1513: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1514: external names of the known functions;
1515: - mkrplso.in is modified.
1516: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1517: - vim syntax file is upgraded;
1518: - a minor mistake is fixed in recherche_instruction_suivante();
1519: - some minor memory leaks are fixed in recherche_type() function. They only
1520: occurs when a syntax error is detected;

1527: - PUTC and PUTR new intrinsics are added.
1528: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1529: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1530: VISIT does not find a name in level 1;
1531: - configure.in script is modified to add a new test (--enable-debug
1532: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1533: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1534: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1535: 'MATRIX' { 2 2 3 } GETR;
1536: - LOGSCALE intrinsic is improved and now, it can be used as
1537: { "main" "auxiliary" X Y } LOGSCALE;
1538: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1539: same than AXES:
1540: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1541: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1542: { { -10 10 } "automatic" } SCALE.
1543: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1544: because it changes only the dimension of the screen. To have a logarithmic
1545: scale, you must use LOGSCALE intrinsic:
1546: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1547: screen on second scale;
1548: - { X X } autoscale and { Y Y } logscale are now invalid;
1549: - *D is added (depth multiplication, for 3D graphics);
1550: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1551: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1552: - a major bug is fixed in GETI instrinsic when it is used with a name
1553: that contains a matrix or a vector (bad upper bounds conditions in
1554: incrementation);
1555: - DISP intrinsic now uses the 33-th flag. When it is not set
1556: (default), a final carriage return is sent to the terminal;
1557: - AXES intrinsic only takes a list that can contains the keywork
1558: "main" or "auxiliary". Before this modification, this keyword was in
1559: the first stack level;
1560: - vim syntax file is upgraded;
1561: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1562: option;
1563: - LAST is now disabled in the main loop of INT intrinsic;
1564: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1565: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1566: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1567: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1568: in 0);
1569: - LAST is disabled in the main loop of DRAW intrinsic;
1570: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1571: evaluation of an equation, the system stack is returned corrupted to the
1572: sequencer;
1573: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1574: of a loop are not integer or real.
1575: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1606: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1607: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1608: is a quick and dirty workaround...);
1609: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1610: - rplconvert is improved.
