281: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
282: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
283: "ALL" IMPLICIT when it runs in interactive mode;
284: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
285: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
286: to use SAVE to manipulate global variables;
287: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
288: subroutines;
289: - fix major memory access violation in evaluation subroutine. Only occurs
290: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;

323: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
324: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
325: corruption. As internal memory management have been improved, a best fit
326: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 327: - gnuplot is upgraded to 4.4.1;
328: - deadlock is fixed in signal handlers: same mutex was used in standard
329: subroutines (without protected sections by sigprocmask() or pthread_sigmask())

332: that has to be evaluated by ->NUM;
1.49 bertrand 333: - rplfile build process is modify to be sure that rplfile is not modified
334: after rpl build stage (to be sure that rplfile checksum is not modified after

344: in parent process;
1.46 bertrand 345: - minor bug is fixed in data injection (POKE) that does not work as expected
346: when child process is protected by NRPROC.

350: systems that does not provide correct POSIX or SysV semaphores subsystem;
351: - a dirty but not quick patch is written to workaround broken siginfo
352: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 353: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process

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

387: in a compiled program, analyse() caught this error twice and randomly aborted
388: with a segmentation error;
389: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
390: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
391: signals;
392: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty

425: should);
426: - minor bugs are fixed in interruptions.c (semaphores values when error is
427: caught);
428: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
429: created by SPAWN;

1.13 bertrand 486: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
487: - in formatted file, string format returned a variable length string even if
488: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 489: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 490: - keyed access files support is added. Currently, only formatted files are

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

552: script file contains a multibyte character;
553: - IN intrinsic is added;
554: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
555: returned false ;
556: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
557: programs;
558: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
559: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

569: - DISP now locks stdout;
570: - rpliconv is added to replace standard iconv provided by operating system.
571: Indeed, conversion between different encodages requires transliteration
572: that is not offered by some iconv utility;
573: - CURRENC and RECODE intrinsics have been written to allow strings conversions;

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

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

607: - some bugfixes are added in process management;
608: - all process management is rewritten to avoid usage of defunct process
609: or thread number;
610: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
611: was called before a pending interruption5 (SIGFSTOP), signal handler uses
612: a freed semaphore and corrupts heap;
613: - CLRERR is added to erase previous errors;
614: - ERRN and ERRM return exception message and number;
615: - major bug is fixed in interruptions.c. All signal are now bufferised
616: when semaphore_liste_threads is null to avoid deadlock. This bug only
617: occured when STOP was sent to a dying thread or process (when this thread or
618: process was running retrait_thread());
619: - matrix rank is computed before matrix inversion;
620: - file locks are added to stdin and stdout. stderr is not locked because
621: all messages written by signal handlers are sent to stderr;

765: SQLQUERY. With all new programs, you can open a real connection to databases;
766: - NRPROC is added. This new intrinsic is used to catch error from child
767: process. Without NRPROC, any errors returned by child process cause
768: main process to abort;
769: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
770: starts a new process). There are no mutexes in RPL/2 because all spawned process
771: use specific context. Nevertheless, shared variables and associated mutexes
772: should be added;

1069: it tries to launch regular gnuplot;
1070: - gnuplot is added to source tree to avoid some trouble between preinstalled
1071: gnuplot and release used by RPL/2. This addition to source tree is
1072: required by some incompatibility between gnuplot releases;

1096: it is possible to execute:
1097:
1098: #!/usr/local/bin/rpl -sc
1099:
1100: TEST
1101: <<
1102: 1 1000 start VAR_S VAR_S2 next

1456: if the main loop is in a program;
1457: - RPL/2 is tested with efence and valgrind;
1458: - configure.in script is modified;
1459: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1460: structure. I don't know why this code was compiled by gcc-3.3... Maybe
1461: another gcc bug...
1462: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)

1495: 2: integer (number of column to be inserted)
1496: 1: column matrix to be inserted;
1497: - major bug was discovered in interface_gnuplot(). It only occurs when

1506: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1507: - SLICESCALE intrinsic is added. Its syntax is
1508: { "automatic" nb_of_levels }
1509: { "discrete" l1 l2 l3 ... }
1510: { "incremental" start incr }
1511: { "incremental" start incr end }
1512: { "automatic" } (default);

1514: - flag 52 is used to automatically update graphics;
1515: - man pages are updated;
1516: - evaluation() is modified to perform evaluation of expressions that contain
1517: '=';
1518: - a minor bug is fixed in AXES intrinsic;
1519: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1520: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1521: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1522: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1523: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1539: - SCLS is added;
1540: - DRWS now uses COLS to draw 2D graphics;
1541: - PPAR and SPAR are written. SPAR returns a list that contains the
1542: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1543: statistical variable, or "DISABLED" if its type is not one of the type of
1544: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1545: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1546: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1547: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1548: disabled. Arguments of EXTERNAL are case sensitive because the external
1549: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1550: of known external functions but add the new list to the last. { "all" }
1551: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1552: external names of the known functions;
1553: - mkrplso.in is modified.
1554: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1555: - vim syntax file is upgraded;
1556: - a minor mistake is fixed in recherche_instruction_suivante();
1557: - some minor memory leaks are fixed in recherche_type() function. They only
1558: occurs when a syntax error is detected;

1560: - INCR and DECR are written (with integer or variable argument);
1561: - CSWP and RSWP are added and tested;
1562: - a minor bug is fixed in analyse.c;
1563: - DEBIAN/control is added to build debian package;
1564: - SCALE is fixed and improved ("automatic" keyword);
1565: - PUTC and PUTR new intrinsics are added.
1566: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1567: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1568: VISIT does not find a name in level 1;
1569: - configure.in script is modified to add a new test (--enable-debug
1570: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1571: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1572: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1573: 'MATRIX' { 2 2 3 } GETR;
1574: - LOGSCALE intrinsic is improved and now, it can be used as
1575: { "main" "auxiliary" X Y } LOGSCALE;
1576: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1577: same than AXES:
1578: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1579: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1580: { { -10 10 } "automatic" } SCALE.
1581: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1582: because it changes only the dimension of the screen. To have a logarithmic
1583: scale, you must use LOGSCALE intrinsic:
1584: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1585: screen on second scale;
1586: - { X X } autoscale and { Y Y } logscale are now invalid;
1587: - *D is added (depth multiplication, for 3D graphics);
1588: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1589: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1590: - a major bug is fixed in GETI instrinsic when it is used with a name
1591: that contains a matrix or a vector (bad upper bounds conditions in
1592: incrementation);
1593: - DISP intrinsic now uses the 33-th flag. When it is not set
1594: (default), a final carriage return is sent to the terminal;
1595: - AXES intrinsic only takes a list that can contains the keywork
1596: "main" or "auxiliary". Before this modification, this keyword was in
1597: the first stack level;
1598: - vim syntax file is upgraded;
1599: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1600: option;
1601: - LAST is now disabled in the main loop of INT intrinsic;
1602: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1603: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1604: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1605: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1606: in 0);
1607: - LAST is disabled in the main loop of DRAW intrinsic;
1608: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1609: evaluation of an equation, the system stack is returned corrupted to the
1610: sequencer;
1611: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1612: of a loop are not integer or real.
1613: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1614: - the compilation stage aborts with an error message when two definitions
1615: have the same name. To improve the compilation() subroutine, I have to
1616: add some tests in gestion_variables.c;
1617: - recherche_type() subroutine ad some other connex subroutines are improved.
1618: Now, some syntax errors about object are caught and do not perform sequencer
1619: hangup;

1621: - Makefile.am's and configure.in scripts are improved.
1622: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1623: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1624: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1625: the boxwidth, 1 by default);
1626: - recherche_type() is rewritten to be faster;
1627: - gsl is upgraded (release 1.3);
1628: - ncurses is upgraded and patched (release 5.3);
1629: - recherche_instruction_suivante() is fixed (string research with included
1630: '"') and rewritten to be faster;
1631: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1632: segfault.
1633: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1641: - a minor bug is fixed in evaluation subroutine;
1642: - vim syntax file is improved;
1643: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1644: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1645: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1646: is a quick and dirty workaround...);
1647: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1648: - rplconvert is improved.
1649: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1665: Now, an expression such as 'A+' returns an error when it is analyzed;
1666: - VISIT intrinsic is added;
1667: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1668: normal mode.

1756: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1757: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1758: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1759: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1760: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1761:
1762: Newton:[~/rpl/rpl] > time make install
1763: ...
1764: real 338m39.623s
1765: user 324m32.290s
1766: sys 10m47.380s
1767: Newton:[~/rpl/rpl] >
1768:
1769: I don't know if you will compile this language on old worstations, but
1770: it is usable ;-) ;
1771: - SYSEVAL is improved. An external program can be called without any shell.
