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

316: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
317: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
318: corruption. As internal memory management have been improved, a best fit
319: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 320: - gnuplot is upgraded to 4.4.1;
321: - deadlock is fixed in signal handlers: same mutex was used in standard
322: subroutines (without protected sections by sigprocmask() or pthread_sigmask())

336: this bug, SIGINJECT signal is not sent by child process but by control thread
337: in parent process;
1.46 bertrand 338: - minor bug is fixed in data injection (POKE) that does not work as expected
339: when child process is protected by NRPROC.

343: systems that does not provide correct POSIX or SysV semaphores subsystem;
344: - a dirty but not quick patch is written to workaround broken siginfo
345: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 346: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process

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

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

418: should);
419: - minor bugs are fixed in interruptions.c (semaphores values when error is
420: caught);
421: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
422: created by SPAWN;

1.13 bertrand 479: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
480: - in formatted file, string format returned a variable length string even if
481: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 482: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 483: - keyed access files support is added. Currently, only formatted files are

494: on a non recoverable system error;
495: - openssl and sqlite3 libraries are added;
496: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
497: variable indicates RPL/2 root directory. If it is not set, root path
498: is given by configure script (d_exec_path);
1.11 bertrand 499: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

532: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
533: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
534: signals sent to main process were not caught because DAEMON did not replace
535: old pid by new one;
536: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
537: evaluation when an error is reported from a subroutine in another subroutine.
538: For example, error was not caught in following program when it is executed with
539: -p option :
540: TEST << iferr TEST2 then end >>
541: TEST2 << 0 inv >>
542: - major bug is fixed in variable management. Some local variables were
543: seen as global ones;

545: script file contains a multibyte character;
546: - IN intrinsic is added;
547: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
548: returned false ;
549: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
550: programs;
551: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
552: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

569: - fprintf is replaced by some functions that allow transliterations between
570: locales;
571: - '"' can now be used in strings ("\"");
572: - iconv is called with -c in preprocessor stage. It is done to write
573: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;

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

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

757: that all programs that worked with old SQL intrinsic can now work with
758: SQLQUERY. With all new programs, you can open a real connection to databases;
759: - NRPROC is added. This new intrinsic is used to catch error from child
760: process. Without NRPROC, any errors returned by child process cause
761: main process to abort;
762: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
763: starts a new process). There are no mutexes in RPL/2 because all spawned process
764: use specific context. Nevertheless, shared variables and associated mutexes
765: should be added;

1060: - external wrapper (rplplot) is written to force usage of gnuplot provided
1061: by RPL/2 if it is built during build process. If this build does not exist,
1062: it tries to launch regular gnuplot;
1063: - gnuplot is added to source tree to avoid some trouble between preinstalled
1064: gnuplot and release used by RPL/2. This addition to source tree is

1088: - Variable management has been rewritten and some tests have been done. Now,
1089: it is possible to execute:
1090:
1091: #!/usr/local/bin/rpl -sc
1092:
1093: TEST
1094: <<
1095: 1 1000 start VAR_S VAR_S2 next
1096: >>
1097:
1098: VAR_S
1099: <<
1100: static 3 -> C << C disp 'C' incr if C 10 > then 'C' volatile end >>
1101: >>

1160: perform a better task synchronization;
1161: - some bugs introduced by locales specific compilations are fixed;
1162: - major memory corruption is fixed in DEPND;
1163: - HELP intrinsic is modified to print a classified output.

1484: - major bug is fixed in C->R intrinsic;
1485: - ROW+ and ROW- are added and tested;
1486: - COL+ and COL- are added and tested. Syntax:
1487: 3: matrix
1488: 2: integer (number of column to be inserted)
1489: 1: column matrix to be inserted;
1490: - major bug was discovered in interface_gnuplot(). It only occurs when

1499: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1500: - SLICESCALE intrinsic is added. Its syntax is
1501: { "automatic" nb_of_levels }
1502: { "discrete" l1 l2 l3 ... }
1503: { "incremental" start incr }
1504: { "incremental" start incr end }
1505: { "automatic" } (default);
1506: - a minor bug (in last stack) is fixed in AXES intrinsic
1507: - flag 52 is used to automatically update graphics;
1508: - man pages are updated;
1509: - evaluation() is modified to perform evaluation of expressions that contain
1510: '=';
1511: - a minor bug is fixed in AXES intrinsic;
1512: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1513: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1514: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1515: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1516: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1523: - '=' is added and tested;
1524: - XCOL and YCOL are added;
1525: - a minor bug in analyse_syntaxique() is fixed;
1526: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1527: structure. ELSE is modified to return an error when ELSE appears in
1528: an ELSE/END structure;
1529: - a major bug is fixed in CYCLE;
1530: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1531: sequencer continues after the end of this loop;
1532: - SCLS is added;
1533: - DRWS now uses COLS to draw 2D graphics;
1534: - PPAR and SPAR are written. SPAR returns a list that contains the
1535: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1536: statistical variable, or "DISABLED" if its type is not one of the type of
1537: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1538: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1539: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1540: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1541: disabled. Arguments of EXTERNAL are case sensitive because the external
1542: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1543: of known external functions but add the new list to the last. { "all" }
1544: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1545: external names of the known functions;
1546: - mkrplso.in is modified.
1547: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1548: - vim syntax file is upgraded;
1549: - a minor mistake is fixed in recherche_instruction_suivante();
1550: - some minor memory leaks are fixed in recherche_type() function. They only
1551: occurs when a syntax error is detected;
1552: - #error and #warning preprocessor macros are added;
1553: - INCR and DECR are written (with integer or variable argument);
1554: - CSWP and RSWP are added and tested;
1555: - a minor bug is fixed in analyse.c;
1556: - DEBIAN/control is added to build debian package;
1557: - SCALE is fixed and improved ("automatic" keyword);
1558: - PUTC and PUTR new intrinsics are added.
1559: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1560: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1561: VISIT does not find a name in level 1;
1562: - configure.in script is modified to add a new test (--enable-debug
1563: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1564: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1565: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1566: 'MATRIX' { 2 2 3 } GETR;
1567: - LOGSCALE intrinsic is improved and now, it can be used as
1568: { "main" "auxiliary" X Y } LOGSCALE;
1569: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1570: same than AXES:
1571: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1572: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1573: { { -10 10 } "automatic" } SCALE.
1574: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1575: because it changes only the dimension of the screen. To have a logarithmic
1576: scale, you must use LOGSCALE intrinsic:
1577: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1578: screen on second scale;
1579: - { X X } autoscale and { Y Y } logscale are now invalid;
1580: - *D is added (depth multiplication, for 3D graphics);
1581: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1582: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1583: - a major bug is fixed in GETI instrinsic when it is used with a name
1584: that contains a matrix or a vector (bad upper bounds conditions in
1585: incrementation);
1586: - DISP intrinsic now uses the 33-th flag. When it is not set
1587: (default), a final carriage return is sent to the terminal;
1588: - AXES intrinsic only takes a list that can contains the keywork
1589: "main" or "auxiliary". Before this modification, this keyword was in
1590: the first stack level;
1591: - vim syntax file is upgraded;
1592: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1593: option;
1594: - LAST is now disabled in the main loop of INT intrinsic;
1595: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1596: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1597: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1598: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1599: in 0);
1600: - LAST is disabled in the main loop of DRAW intrinsic;
1601: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1602: evaluation of an equation, the system stack is returned corrupted to the
1603: sequencer;
1604: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1605: of a loop are not integer or real.
1606: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1607: - the compilation stage aborts with an error message when two definitions
1608: have the same name. To improve the compilation() subroutine, I have to
1609: add some tests in gestion_variables.c;
1610: - recherche_type() subroutine ad some other connex subroutines are improved.
1611: Now, some syntax errors about object are caught and do not perform sequencer
1612: hangup;
1613: - readline is upgraded (minor compilation bug with recent gcc);
1614: - Makefile.am's and configure.in scripts are improved.
1615: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1616: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1617: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1618: the boxwidth, 1 by default);
1619: - recherche_type() is rewritten to be faster;
1620: - gsl is upgraded (release 1.3);
1621: - ncurses is upgraded and patched (release 5.3);
1622: - recherche_instruction_suivante() is fixed (string research with included
1623: '"') and rewritten to be faster;
1624: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1625: segfault.
1626: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1634: - a minor bug is fixed in evaluation subroutine;
1635: - vim syntax file is improved;
1636: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1637: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1638: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1639: is a quick and dirty workaround...);
1640: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1641: - rplconvert is improved.
1642: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1658: Now, an expression such as 'A+' returns an error when it is analyzed;
1659: - VISIT intrinsic is added;
1660: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1661: normal mode.

1749: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1750: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1751: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1752: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1753: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1754:
1755: Newton:[~/rpl/rpl] > time make install
1756: ...
1757: real 338m39.623s
1758: user 324m32.290s
1759: sys 10m47.380s
1760: Newton:[~/rpl/rpl] >
1761:
1762: I don't know if you will compile this language on old worstations, but
1763: it is usable ;-) ;
1764: - SYSEVAL is improved. An external program can be called without any shell.
