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

318: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
319: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
320: corruption. As internal memory management have been improved, a best fit
321: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 322: - gnuplot is upgraded to 4.4.1;
323: - deadlock is fixed in signal handlers: same mutex was used in standard

339: in parent process;
1.46 bertrand 340: - minor bug is fixed in data injection (POKE) that does not work as expected
341: when child process is protected by NRPROC.

345: systems that does not provide correct POSIX or SysV semaphores subsystem;
346: - a dirty but not quick patch is written to workaround broken siginfo
347: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 348: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process

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

382: in a compiled program, analyse() caught this error twice and randomly aborted
383: with a segmentation error;
384: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
385: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
386: signals;

1.13 bertrand 481: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
482: - in formatted file, string format returned a variable length string even if
483: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 484: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 485: - keyed access files support is added. Currently, only formatted files are

496: on a non recoverable system error;
497: - openssl and sqlite3 libraries are added;
498: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
499: variable indicates RPL/2 root directory. If it is not set, root path
500: is given by configure script (d_exec_path);
1.11 bertrand 501: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

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

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

571: - fprintf is replaced by some functions that allow transliterations between
572: locales;
573: - '"' can now be used in strings ("\"");
574: - iconv is called with -c in preprocessor stage. It is done to write
575: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
576: - double free is fixed in liberation() (type SQL, only occurs when locale is
577: set);
578: - LOCALIZATION, UCASE and LCASE are added;

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

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

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

1089: * Sun Jan 21 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.00pre8t (RPL/2)
1090: - Variable management has been rewritten and some tests have been done. Now,
1091: it is possible to execute:
1092:
1093: #!/usr/local/bin/rpl -sc
1094:
1095: TEST
1096: <<
1097: 1 1000 start VAR_S VAR_S2 next
1098: >>
1099:
1100: VAR_S
1101: <<
1102: static 3 -> C << C disp 'C' incr if C 10 > then 'C' volatile end >>
1103: >>

1456: another gcc bug...
1457: * Fri Jul 25 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7b (RPL/2)

1484: 1: x;
1485: - ->Q intrinsic is added;
1486: - major bug is fixed in C->R intrinsic;
1487: - ROW+ and ROW- are added and tested;
1488: - COL+ and COL- are added and tested. Syntax:
1489: 3: matrix
1490: 2: integer (number of column to be inserted)
1491: 1: column matrix to be inserted;
1492: - major bug was discovered in interface_gnuplot(). It only occurs when

1501: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1502: - SLICESCALE intrinsic is added. Its syntax is
1503: { "automatic" nb_of_levels }
1504: { "discrete" l1 l2 l3 ... }
1505: { "incremental" start incr }
1506: { "incremental" start incr end }
1507: { "automatic" } (default);
1508: - a minor bug (in last stack) is fixed in AXES intrinsic
1509: - flag 52 is used to automatically update graphics;
1510: - man pages are updated;
1511: - evaluation() is modified to perform evaluation of expressions that contain
1512: '=';
1513: - a minor bug is fixed in AXES intrinsic;
1514: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1515: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1516: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1517: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1518: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1534: - SCLS is added;
1535: - DRWS now uses COLS to draw 2D graphics;
1536: - PPAR and SPAR are written. SPAR returns a list that contains the
1537: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1538: statistical variable, or "DISABLED" if its type is not one of the type of
1539: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1540: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1541: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1542: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1543: disabled. Arguments of EXTERNAL are case sensitive because the external
1544: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1545: of known external functions but add the new list to the last. { "all" }
1546: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1547: external names of the known functions;
1548: - mkrplso.in is modified.
1549: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1550: - vim syntax file is upgraded;
1551: - a minor mistake is fixed in recherche_instruction_suivante();
1552: - some minor memory leaks are fixed in recherche_type() function. They only
1553: occurs when a syntax error is detected;

1555: - INCR and DECR are written (with integer or variable argument);
1556: - CSWP and RSWP are added and tested;
1557: - a minor bug is fixed in analyse.c;
1558: - DEBIAN/control is added to build debian package;
1559: - SCALE is fixed and improved ("automatic" keyword);
1560: - PUTC and PUTR new intrinsics are added.
1561: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1562: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1563: VISIT does not find a name in level 1;
1564: - configure.in script is modified to add a new test (--enable-debug
1565: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1566: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1567: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1568: 'MATRIX' { 2 2 3 } GETR;
1569: - LOGSCALE intrinsic is improved and now, it can be used as
1570: { "main" "auxiliary" X Y } LOGSCALE;
1571: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1572: same than AXES:
1573: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1574: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1575: { { -10 10 } "automatic" } SCALE.
1576: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1577: because it changes only the dimension of the screen. To have a logarithmic
1578: scale, you must use LOGSCALE intrinsic:
1579: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1580: screen on second scale;
1581: - { X X } autoscale and { Y Y } logscale are now invalid;
1582: - *D is added (depth multiplication, for 3D graphics);
1583: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1584: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1585: - a major bug is fixed in GETI instrinsic when it is used with a name
1586: that contains a matrix or a vector (bad upper bounds conditions in
1587: incrementation);
1588: - DISP intrinsic now uses the 33-th flag. When it is not set
1589: (default), a final carriage return is sent to the terminal;
1590: - AXES intrinsic only takes a list that can contains the keywork
1591: "main" or "auxiliary". Before this modification, this keyword was in
1592: the first stack level;
1593: - vim syntax file is upgraded;
1594: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1595: option;
1596: - LAST is now disabled in the main loop of INT intrinsic;
1597: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1598: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1599: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1600: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1601: in 0);
1602: - LAST is disabled in the main loop of DRAW intrinsic;
1603: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1604: evaluation of an equation, the system stack is returned corrupted to the
1605: sequencer;
1606: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1607: of a loop are not integer or real.
1608: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1609: - the compilation stage aborts with an error message when two definitions
1610: have the same name. To improve the compilation() subroutine, I have to
1611: add some tests in gestion_variables.c;
1612: - recherche_type() subroutine ad some other connex subroutines are improved.
1613: Now, some syntax errors about object are caught and do not perform sequencer
1614: hangup;

1616: - Makefile.am's and configure.in scripts are improved.
1617: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1618: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1619: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1620: the boxwidth, 1 by default);
1621: - recherche_type() is rewritten to be faster;
1622: - gsl is upgraded (release 1.3);
1623: - ncurses is upgraded and patched (release 5.3);
1624: - recherche_instruction_suivante() is fixed (string research with included
1625: '"') and rewritten to be faster;
1626: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1627: segfault.
1628: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1636: - a minor bug is fixed in evaluation subroutine;
1637: - vim syntax file is improved;
1638: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1639: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1640: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1641: is a quick and dirty workaround...);
1642: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1643: - rplconvert is improved.
1644: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1660: Now, an expression such as 'A+' returns an error when it is analyzed;
1661: - VISIT intrinsic is added;
1662: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1663: normal mode.

1751: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1752: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1753: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1754: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1755: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1756:
1757: Newton:[~/rpl/rpl] > time make install
1758: ...
1759: real 338m39.623s
1760: user 324m32.290s

1762: Newton:[~/rpl/rpl] >
1763:
1764: I don't know if you will compile this language on old worstations, but
1765: it is usable ;-) ;
1766: - SYSEVAL is improved. An external program can be called without any shell.
