306: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
307: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
308: "ALL" IMPLICIT when it runs in interactive mode;
309: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
310: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
311: to use SAVE to manipulate global variables;
312: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
313: subroutines;
314: - fix major memory access violation in evaluation subroutine. Only occurs
315: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
316: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
317: when X was a vector or a table.

348: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
349: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
350: corruption. As internal memory management have been improved, a best fit
351: allocator like ptmalloc3 is not required anymore;
352: - gnuplot is upgraded to 4.4.1;
353: - deadlock is fixed in signal handlers: same mutex was used in standard
354: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
355: and signal handlers. A new signal handler specific mutex is added;
356: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
357: that has to be evaluated by ->NUM;
358: - rplfile build process is modify to be sure that rplfile is not modified
359: after rpl build stage (to be sure that rplfile checksum is not modified after
360: rpl compilation);
361: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
362: modified to remove yacc code and renamed;

367: parent process was not interrupted if it is not group master process. To fix
368: this bug, SIGINJECT signal is not sent by child process but by control thread
369: in parent process;
370: - minor bug is fixed in data injection (POKE) that does not work as expected
371: when child process is protected by NRPROC.
372: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
373: - --enable-sysv-sems is added to configure script to use SystemV semaphores
374: functions instead of POSIX functions. This function is disabled or forced on
375: systems that does not provide correct POSIX or SysV semaphores subsystem;
376: - a dirty but not quick patch is written to workaround broken siginfo
377: structures. This patch has been successfully tested. It uses a segment of
378: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process

525: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
526: on a non recoverable system error;
527: - openssl and sqlite3 libraries are added;
528: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
529: variable indicates RPL/2 root directory. If it is not set, root path
530: is given by configure script (d_exec_path);
531: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

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

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

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

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

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

772: - a mutex is added to each object (before this modification,
773: RPL/2 used a global mutex and performances in multithreaded programs were very
774: poor.);
775: - ALARM is now interruptible;
776: - both PUT and PUTI intrinsics are improved and do not copy list and table
777: when nombre_occurrences == 1;

789: that all programs that worked with old SQL intrinsic can now work with
790: SQLQUERY. With all new programs, you can open a real connection to databases;
791: - NRPROC is added. This new intrinsic is used to catch error from child
792: process. Without NRPROC, any errors returned by child process cause
793: main process to abort;
794: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
795: starts a new process). There are no mutexes in RPL/2 because all spawned process
796: use specific context. Nevertheless, shared variables and associated mutexes
797: should be added;

938: - as old file program was bugged, a new option is added to configure script.
939: When configure is called with --disable-encoding-autodetection, make does not
940: try to detect source encoding. Please, do not use if RPL/2 can be built
941: without this option !
942: - new garbage collector (and more efficient) is written;
943: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
944: not support real time signals, RPL/2 cannot use multitasking functions;
945: - error returned by preprocessor are now catched by RPL/2;
946: - -p option is added. With this option, all scripts are compiled before

1091: - HELP function is rewritten to be more friendly (a la OpenVMS);
1092: - external wrapper (rplplot) is written to force usage of gnuplot provided
1093: by RPL/2 if it is built during build process. If this build does not exist,
1094: it tries to launch regular gnuplot;
1095: - gnuplot is added to source tree to avoid some trouble between preinstalled
1096: gnuplot and release used by RPL/2. This addition to source tree is
1097: required by some incompatibility between gnuplot releases;

1103: not writable;
1104: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1105: error scrutation.

1133: >>
1134:
1135: VAR_S2
1136: <<
1137: static 3 -> C << C disp 'C' decr >>
1138: >>

1140: - configure.in script is added in lapack subtree;
1141: - VARS is modified to display variables status (LOCKED/UNLOCKED and
1142: STATIC/VOLATILE/PARAMETER/VARIABLE);
1143: - STATIC and VOLATILE intrinsics are added to specify static variables. A
1144: static variable can be transformed into volatile with VOLATILE.
1145: With STATIC, next variables created by '->' are static;
1146: - PROTECT and UNPROTECT are added to protect variables against write
1147: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1148: versions of PROTECT and UNPROTECT that only deal with global variables
1149: (see RCL/SAVE);
1150: - variable management routines have been rewritten. The new ones are
1151: uncompatible with the old ones. Before these changes, a local variable
1152: was exported to a child subroutine, but cannot be modified into this
1153: child subroutine. Now, a local variable is accessible only in its subroutine;
1154: - SAVE intrinsic is added to manipulate global variables;
1155: - SUSPEND is written. RPL/2 waits for a SIGCONT signal;
1156: - SORT, COL->, ->COL, ROW->, ROW-> intrinsics are written;

1531: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1532: - SLICESCALE intrinsic is added. Its syntax is
1533: { "automatic" nb_of_levels }
1534: { "discrete" l1 l2 l3 ... }
1535: { "incremental" start incr }
1536: { "incremental" start incr end }
1537: { "automatic" } (default);
1538: - a minor bug (in last stack) is fixed in AXES intrinsic
1539: - flag 52 is used to automatically update graphics;
1540: - man pages are updated;
1541: - evaluation() is modified to perform evaluation of expressions that contain
1542: '=';
1543: - a minor bug is fixed in AXES intrinsic;
1544: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1545: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1546: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1547: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1548: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1555: - '=' is added and tested;
1556: - XCOL and YCOL are added;
1557: - a minor bug in analyse_syntaxique() is fixed;
1558: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1559: structure. ELSE is modified to return an error when ELSE appears in
1560: an ELSE/END structure;
1561: - a major bug is fixed in CYCLE;

1564: - SCLS is added;
1565: - DRWS now uses COLS to draw 2D graphics;
1566: - PPAR and SPAR are written. SPAR returns a list that contains the
1567: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1568: statistical variable, or "DISABLED" if its type is not one of the type of
1569: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1570: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1571: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1572: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1573: disabled. Arguments of EXTERNAL are case sensitive because the external
1574: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1575: of known external functions but add the new list to the last. { "all" }
1576: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1577: external names of the known functions;
1578: - mkrplso.in is modified.
1579: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1580: - vim syntax file is upgraded;
1581: - a minor mistake is fixed in recherche_instruction_suivante();
1582: - some minor memory leaks are fixed in recherche_type() function. They only
1583: occurs when a syntax error is detected;

1590: - PUTC and PUTR new intrinsics are added.
1591: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1592: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1593: VISIT does not find a name in level 1;
1594: - configure.in script is modified to add a new test (--enable-debug
1595: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1596: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1597: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1598: 'MATRIX' { 2 2 3 } GETR;
1599: - LOGSCALE intrinsic is improved and now, it can be used as
1600: { "main" "auxiliary" X Y } LOGSCALE;
1601: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1602: same than AXES:
1603: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1604: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1605: { { -10 10 } "automatic" } SCALE.
1606: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1607: because it changes only the dimension of the screen. To have a logarithmic
1608: scale, you must use LOGSCALE intrinsic:
1609: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1610: screen on second scale;
1611: - { X X } autoscale and { Y Y } logscale are now invalid;
1612: - *D is added (depth multiplication, for 3D graphics);
1613: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1614: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1615: - a major bug is fixed in GETI instrinsic when it is used with a name
1616: that contains a matrix or a vector (bad upper bounds conditions in
1617: incrementation);
1618: - DISP intrinsic now uses the 33-th flag. When it is not set
1619: (default), a final carriage return is sent to the terminal;
1620: - AXES intrinsic only takes a list that can contains the keywork
1621: "main" or "auxiliary". Before this modification, this keyword was in
1622: the first stack level;
1623: - vim syntax file is upgraded;
1624: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1625: option;
1626: - LAST is now disabled in the main loop of INT intrinsic;
1627: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1628: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1629: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1630: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1631: in 0);
1632: - LAST is disabled in the main loop of DRAW intrinsic;
1633: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1634: evaluation of an equation, the system stack is returned corrupted to the
1635: sequencer;
1636: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1637: of a loop are not integer or real.
1638: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1648: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1649: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1666: - a minor bug is fixed in evaluation subroutine;
1667: - vim syntax file is improved;
1668: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1669: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1670: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1671: is a quick and dirty workaround...);
1672: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1673: - rplconvert is improved.
