1.174 bertrand 3: - sqlite is upgraded;
1.173 bertrand 4: - Major regression is fixed in IFERR/END structure;
1.172 bertrand 5: - Major regression is fixed in evaluation(). Local variables were exported

7: * Mon Apr 1 2013 BERTRAND Joël <rpl@systella.fr> rpl-4.1.13 (RPL/2)
1.169 bertrand 8: - integer overflows have been fixed (NEG, ABS, minus);
1.168 bertrand 9: - global variables can now be recalled from ATEXIT procedure;
1.167 bertrand 10: - ATEXIT registered procedure is now executed even if program is stopped by
11: SIGINT;
1.165 bertrand 12: - minor bug is fixed in TOKENIZE intrinsic instruction. TOKENIZE did not work on
13: a copy of input string;
1.164 bertrand 14: - major bug (segfault) is fixed in liste_variables(). It only occurs
15: when this function is called with shared variables;
1.163 bertrand 16: - all internal data are now stored in 64 bits wide integers (even is 32 bits
17: ABI is selected);

1.160 bertrand 23: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
24: internal value was good but RPL/2 was not able to correctly display
25: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented
1.171 bertrand 26: in integer. All abs(), fabs() and labs() present in source code have been

34: creation even if a transliteration error is caught;
35: - major bug is fixed in evaluation(). System stack was not correctly
36: destacked when execution error occurs;
1.154 bertrand 37: - major bug is fixed in READ (socket interface);
38: - minor bug is fixed in analyse_flux().

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

281: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
282: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
283: corruption. As internal memory management have been improved, a best fit
284: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 285: - gnuplot is upgraded to 4.4.1;
286: - deadlock is fixed in signal handlers: same mutex was used in standard
287: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
288: and signal handlers. A new signal handler specific mutex is added;

290: that has to be evaluated by ->NUM;
1.49 bertrand 291: - rplfile build process is modify to be sure that rplfile is not modified
292: after rpl build stage (to be sure that rplfile checksum is not modified after

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

1.43 bertrand 306: - --enable-sysv-sems is added to configure script to use SystemV semaphores
307: functions instead of POSIX functions. This function is disabled or forced on
308: systems that does not provide correct POSIX or SysV semaphores subsystem;
309: - a dirty but not quick patch is written to workaround broken siginfo
310: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 311: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 312: (Unix PID);
1.41 bertrand 313: - some OpenBSD's hacks are added;

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

344: - major bug is fixed in analyse() subroutine. When evaluation() returned error
345: in a compiled program, analyse() caught this error twice and randomly aborted
346: with a segmentation error;
347: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
348: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
349: signals;

376: process;
377: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
378: discovered in Solaris thread safe allocators (libmalloc and libumem) that

383: should);
384: - minor bugs are fixed in interruptions.c (semaphores values when error is
385: caught);
386: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
387: created by SPAWN;
388: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute

397: information about shared variable was not copied to new processus structure;
1.19 bertrand 398: - some little memory leaks are fixed in evaluation(), recherche_type() and
399: sequenceur(). They only occured when syntax error were caught;
400: - IMPLICIT causes execution error instead system error;

459: on a non recoverable system error;
460: - openssl and sqlite3 libraries are added;
461: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this

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

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

534: - fprintf is replaced by some functions that allow transliterations between
535: locales;
536: - '"' can now be used in strings ("\"");
537: - iconv is called with -c in preprocessor stage. It is done to write

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

565: - some bugfixes are added in process management;
566: - all process management is rewritten to avoid usage of defunct process
567: or thread number;

569: was called before a pending interruption5 (SIGFSTOP), signal handler uses
570: a freed semaphore and corrupts heap;
571: - CLRERR is added to erase previous errors;
572: - ERRN and ERRM return exception message and number;
573: - major bug is fixed in interruptions.c. All signal are now bufferised
574: when semaphore_liste_threads is null to avoid deadlock. This bug only
575: occured when STOP was sent to a dying thread or process (when this thread or
576: process was running retrait_thread());
577: - matrix rank is computed before matrix inversion;
578: - file locks are added to stdin and stdout. stderr is not locked because

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

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

1008: ends;
1009: - MEM does not report static variable sizes;
1010: - minor bug is fixed in HELP intrinsic. When the last instruction was not
1011: known, HELP function was pushed in operational stack. HELP did not work

1024: - HELP function is rewritten to be more friendly (a la OpenVMS);
1025: - external wrapper (rplplot) is written to force usage of gnuplot provided
1026: by RPL/2 if it is built during build process. If this build does not exist,
1027: it tries to launch regular gnuplot;
1028: - gnuplot is added to source tree to avoid some trouble between preinstalled
1029: gnuplot and release used by RPL/2. This addition to source tree is
1030: required by some incompatibility between gnuplot releases;

1036: not writable;
1037: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1038: error scrutation.

1073: - configure.in script is added in lapack subtree;
1074: - VARS is modified to display variables status (LOCKED/UNLOCKED and
1075: STATIC/VOLATILE/PARAMETER/VARIABLE);
1076: - STATIC and VOLATILE intrinsics are added to specify static variables. A
1077: static variable can be transformed into volatile with VOLATILE.
1078: With STATIC, next variables created by '->' are static;
1079: - PROTECT and UNPROTECT are added to protect variables against write
1080: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1081: versions of PROTECT and UNPROTECT that only deal with global variables
1082: (see RCL/SAVE);
1083: - variable management routines have been rewritten. The new ones are
1084: uncompatible with the old ones. Before these changes, a local variable
1085: was exported to a child subroutine, but cannot be modified into this
1086: child subroutine. Now, a local variable is accessible only in its subroutine;
1087: - SAVE intrinsic is added to manipulate global variables;
1088: - SUSPEND is written. RPL/2 waits for a SIGCONT signal;
1089: - SORT, COL->, ->COL, ROW->, ROW-> intrinsics are written;

1097: that avoid a complete build;
1098: - CTRL+Z and CTRL+C signals only perform actions on main process;
1099: - major bugs are fixed in multitasking capabilities (some mistakes with
1100: mutexes and several terminated child process cannot be closed by the
1101: operating system);

1464: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1465: - SLICESCALE intrinsic is added. Its syntax is
1466: { "automatic" nb_of_levels }
1467: { "discrete" l1 l2 l3 ... }
1468: { "incremental" start incr }
1469: { "incremental" start incr end }
1470: { "automatic" } (default);
1471: - a minor bug (in last stack) is fixed in AXES intrinsic
1472: - flag 52 is used to automatically update graphics;
1473: - man pages are updated;
1474: - evaluation() is modified to perform evaluation of expressions that contain
1475: '=';
1476: - a minor bug is fixed in AXES intrinsic;
1477: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1478: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1479: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1480: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1481: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;
1482: - PLOTTER is added to draw statistical clouds with lines;
1483: - C and H source files now include vim parameters;
1484: - vim syntax file is modified to include new intrinsics;
1485: - static archive is modified to include all required libraries needed by
1486: RPL/2.
1487: * Sun May 4 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6i (RPL/2)
1488: - '=' is added and tested;
1489: - XCOL and YCOL are added;
1490: - a minor bug in analyse_syntaxique() is fixed;
1491: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1492: structure. ELSE is modified to return an error when ELSE appears in
1493: an ELSE/END structure;
1494: - a major bug is fixed in CYCLE;
1495: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1496: sequencer continues after the end of this loop;
1497: - SCLS is added;
1498: - DRWS now uses COLS to draw 2D graphics;
1499: - PPAR and SPAR are written. SPAR returns a list that contains the
1500: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1501: statistical variable, or "DISABLED" if its type is not one of the type of
1502: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1503: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1504: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1505: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1506: disabled. Arguments of EXTERNAL are case sensitive because the external
1507: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1508: of known external functions but add the new list to the last. { "all" }
1509: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1510: external names of the known functions;
1511: - mkrplso.in is modified.
1512: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1513: - vim syntax file is upgraded;
1514: - a minor mistake is fixed in recherche_instruction_suivante();
1515: - some minor memory leaks are fixed in recherche_type() function. They only
1516: occurs when a syntax error is detected;
1517: - #error and #warning preprocessor macros are added;
1518: - INCR and DECR are written (with integer or variable argument);
1519: - CSWP and RSWP are added and tested;
1520: - a minor bug is fixed in analyse.c;
1521: - DEBIAN/control is added to build debian package;
1522: - SCALE is fixed and improved ("automatic" keyword);
1523: - PUTC and PUTR new intrinsics are added.
1524: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1525: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1526: VISIT does not find a name in level 1;
1527: - configure.in script is modified to add a new test (--enable-debug
1528: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1529: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1530: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1531: 'MATRIX' { 2 2 3 } GETR;
1532: - LOGSCALE intrinsic is improved and now, it can be used as
1533: { "main" "auxiliary" X Y } LOGSCALE;
1534: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1535: same than AXES:
1536: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1537: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1538: { { -10 10 } "automatic" } SCALE.
1539: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1540: because it changes only the dimension of the screen. To have a logarithmic
1541: scale, you must use LOGSCALE intrinsic:
1542: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1543: screen on second scale;
1544: - { X X } autoscale and { Y Y } logscale are now invalid;
1545: - *D is added (depth multiplication, for 3D graphics);
1546: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1547: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1548: - a major bug is fixed in GETI instrinsic when it is used with a name
1549: that contains a matrix or a vector (bad upper bounds conditions in
1550: incrementation);
1551: - DISP intrinsic now uses the 33-th flag. When it is not set
1552: (default), a final carriage return is sent to the terminal;
1553: - AXES intrinsic only takes a list that can contains the keywork
1554: "main" or "auxiliary". Before this modification, this keyword was in
1555: the first stack level;
1556: - vim syntax file is upgraded;
1557: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1558: option;
1559: - LAST is now disabled in the main loop of INT intrinsic;
1560: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1561: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1562: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1563: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1564: in 0);
1565: - LAST is disabled in the main loop of DRAW intrinsic;
1566: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1567: evaluation of an equation, the system stack is returned corrupted to the
1568: sequencer;
1569: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1570: of a loop are not integer or real.
1571: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1572: - the compilation stage aborts with an error message when two definitions
1573: have the same name. To improve the compilation() subroutine, I have to
1574: add some tests in gestion_variables.c;
1575: - recherche_type() subroutine ad some other connex subroutines are improved.
1576: Now, some syntax errors about object are caught and do not perform sequencer

1579: - Makefile.am's and configure.in scripts are improved.
1580: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1581: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1582: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1583: the boxwidth, 1 by default);
1584: - recherche_type() is rewritten to be faster;
1585: - gsl is upgraded (release 1.3);
1586: - ncurses is upgraded and patched (release 5.3);
1587: - recherche_instruction_suivante() is fixed (string research with included
1588: '"') and rewritten to be faster;

1599: - a minor bug is fixed in evaluation subroutine;
1600: - vim syntax file is improved;
1601: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1602: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1603: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1604: is a quick and dirty workaround...);
1605: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1606: - rplconvert is improved.

1716: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1717: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1718: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1719:
1720: Newton:[~/rpl/rpl] > time make install
