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

361: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
362: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
363: corruption. As internal memory management have been improved, a best fit
364: allocator like ptmalloc3 is not required anymore;
365: - gnuplot is upgraded to 4.4.1;
366: - deadlock is fixed in signal handlers: same mutex was used in standard
367: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
368: and signal handlers. A new signal handler specific mutex is added;
369: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
370: that has to be evaluated by ->NUM;
371: - rplfile build process is modify to be sure that rplfile is not modified
372: after rpl build stage (to be sure that rplfile checksum is not modified after

380: parent process was not interrupted if it is not group master process. To fix
381: this bug, SIGINJECT signal is not sent by child process but by control thread
382: in parent process;
383: - minor bug is fixed in data injection (POKE) that does not work as expected
384: when child process is protected by NRPROC.
385: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
386: - --enable-sysv-sems is added to configure script to use SystemV semaphores
387: functions instead of POSIX functions. This function is disabled or forced on
388: systems that does not provide correct POSIX or SysV semaphores subsystem;
389: - a dirty but not quick patch is written to workaround broken siginfo
390: structures. This patch has been successfully tested. It uses a segment of
391: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
392: (Unix PID);
393: - some OpenBSD's hacks are added;
394: - broken siginfo->si_pid field is now checked by configure script;
395: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

412: Level 0 and 1 variables adresses were swapped when a global variable masked
413: a name of RPL/2 routine;
414: - major bug is fixed in global variable creation subroutine. When a global
415: variable was created and when a local variable existed with the same name,
416: computed address of global variable was wrong;
417: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
418: is forced in front of all libraries.
419: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
420: - BACKTRACE intrinsic is added;

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

453: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
454: and to not use swap;
455: - major bug is fixed in sql support. SQL connections were closed in all chield
456: process;
457: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
458: discovered in Solaris thread safe allocators (libmalloc and libumem) that
459: are first fit class allocators. Solaris libmtmalloc works better and is
460: a best fit class allocator but its performance is poor than ptmalloc3
461: performance;

477: information about shared variable was not copied to new processus structure;
478: - some little memory leaks are fixed in evaluation(), recherche_type() and
479: sequenceur(). They only occured when syntax error were caught;
480: - IMPLICIT causes execution error instead system error;
481: - Hurd support is improved but currently broken because Hurd does not support
482: SIG_INFO. Work in progress;
483: - OpenBSD specific support is removed from sources;
484: - support for Mac OS X and Windows/Cygwin is added.
485: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

524: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
525: - in formatted file, string format returned a variable length string even if
526: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
527: a variable length string and 'CHARACTER*(n)' a fixed length string;
528: - keyed access files support is added. Currently, only formatted files are
529: supported;
530: - direct access files support is added. Currenlty, these files can only be used
531: in formatted mode;

533: in string are escaped;
534: - all formatted files are now converted into UTF-8;
535: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
536: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
537: each execution (md5 and sha1 sums) to enhance security. If one of these tools
538: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
539: on a non recoverable system error;
540: - openssl and sqlite3 libraries are added;
541: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
542: variable indicates RPL/2 root directory. If it is not set, root path
543: is given by configure script (d_exec_path);
544: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

578: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
579: signals sent to main process were not caught because DAEMON did not replace
580: old pid by new one;
581: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
582: evaluation when an error is reported from a subroutine in another subroutine.
583: For example, error was not caught in following program when it is executed with
584: -p option :
585: TEST << iferr TEST2 then end >>
586: TEST2 << 0 inv >>
587: - major bug is fixed in variable management. Some local variables were
588: seen as global ones;

590: script file contains a multibyte character;
591: - IN intrinsic is added;
592: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
593: returned false ;

605: - major bug is fixed in OPEN (TCP/IPv4 sockets).
606: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
607: - DISP now locks stdout;
608: - rpliconv is added to replace standard iconv provided by operating system.
609: Indeed, conversion between different encodages requires transliteration
610: that is not offered by some iconv utility;
611: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
612: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

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

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

771: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)
772: - an estimation of future stack elements is added to avoid some costly memory
773: allocations. This function has a positive impact on execution speed;
774: - PSHPRFL and PULPRFL have been added;
775: - RPL/2 can be built on Solaris 64 bits with some minor scripts alterations.
776: See README for more explanations;
777: - MTXSTATUS intrinsic is added;
778: - YIELD intrinsic is added;
779: - ERRM is fixed. In some cases, ERRM uses some uninitialized pointers;
780: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
781: static variable that is shared by multiple threads;
782: - '->' intrinsic is improved. All object copies have been avoided;
783: - -n flag is added to catch HUP signal. stderr and stdout are redirected
784: to a file, stdin is redirected to /dev/null when control process is killed;
785: - a mutex is added to each object (before this modification,
786: RPL/2 used a global mutex and performances in multithreaded programs were very
787: poor.);
788: - ALARM is now interruptible;
789: - both PUT and PUTI intrinsics are improved and do not copy list and table
790: when nombre_occurrences == 1;
791: - COPY intrinsic is added. Argument (that can be pointed from some objects)
792: is replaced by a new copy of itself;
793: - memory leak is fixed in sequenceur(). It only occurs when an execution error

801: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
802: that all programs that worked with old SQL intrinsic can now work with
803: SQLQUERY. With all new programs, you can open a real connection to databases;
804: - NRPROC is added. This new intrinsic is used to catch error from child
805: process. Without NRPROC, any errors returned by child process cause
806: main process to abort;
807: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
808: starts a new process). There are no mutexes in RPL/2 because all spawned process
809: use specific context. Nevertheless, shared variables and associated mutexes
810: should be added;
811: - -D flag and DAEMONIZE intrinsic have been added;
812: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

827: it's done. Data integrity is now respected during transmission (POKE, SEND and
828: SWI);
829: - ITRACE is added. This intrinsic is only used to debug internal structures and
830: should not be used in regular programs;
831: - SWISTATUS is written;
832: - WFACK is written;
833: - rplcore files are now able to handle compilation errors;

951: - as old file program was bugged, a new option is added to configure script.
952: When configure is called with --disable-encoding-autodetection, make does not
953: try to detect source encoding. Please, do not use if RPL/2 can be built
954: without this option !
955: - new garbage collector (and more efficient) is written;

957: not support real time signals, RPL/2 cannot use multitasking functions;
958: - error returned by preprocessor are now catched by RPL/2;
959: - -p option is added. With this option, all scripts are compiled before
960: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
961: 40% faster;
962: - read and write operations in pipe() are rewritten to be sure that such
963: operations are atomic;
964: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1104: - HELP function is rewritten to be more friendly (a la OpenVMS);
1105: - external wrapper (rplplot) is written to force usage of gnuplot provided
1106: by RPL/2 if it is built during build process. If this build does not exist,
1107: it tries to launch regular gnuplot;
1108: - gnuplot is added to source tree to avoid some trouble between preinstalled
1109: gnuplot and release used by RPL/2. This addition to source tree is
1110: required by some incompatibility between gnuplot releases;

1533: 2: integer (number of column to be inserted)
1534: 1: column matrix to be inserted;
1535: - major bug was discovered in interface_gnuplot(). It only occurs when
1536: the subroutine reduces the graphical depth. It is now fixed;

1544: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1545: - SLICESCALE intrinsic is added. Its syntax is
1546: { "automatic" nb_of_levels }
1547: { "discrete" l1 l2 l3 ... }
1548: { "incremental" start incr }
1549: { "incremental" start incr end }
1550: { "automatic" } (default);
1551: - a minor bug (in last stack) is fixed in AXES intrinsic
1552: - flag 52 is used to automatically update graphics;
1553: - man pages are updated;
1554: - evaluation() is modified to perform evaluation of expressions that contain
1555: '=';
1556: - a minor bug is fixed in AXES intrinsic;
1557: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1558: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1559: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1560: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1561: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1568: - '=' is added and tested;
1569: - XCOL and YCOL are added;
1570: - a minor bug in analyse_syntaxique() is fixed;
1571: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1572: structure. ELSE is modified to return an error when ELSE appears in
1573: an ELSE/END structure;
1574: - a major bug is fixed in CYCLE;
1575: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1576: sequencer continues after the end of this loop;
1577: - SCLS is added;
1578: - DRWS now uses COLS to draw 2D graphics;
1579: - PPAR and SPAR are written. SPAR returns a list that contains the
1580: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1581: statistical variable, or "DISABLED" if its type is not one of the type of
1582: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1583: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1584: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1585: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1586: disabled. Arguments of EXTERNAL are case sensitive because the external
1587: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1588: of known external functions but add the new list to the last. { "all" }
1589: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1590: external names of the known functions;
1591: - mkrplso.in is modified.
1592: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1593: - vim syntax file is upgraded;
1594: - a minor mistake is fixed in recherche_instruction_suivante();
1595: - some minor memory leaks are fixed in recherche_type() function. They only
1596: occurs when a syntax error is detected;

1598: - INCR and DECR are written (with integer or variable argument);
1599: - CSWP and RSWP are added and tested;
1600: - a minor bug is fixed in analyse.c;
1601: - DEBIAN/control is added to build debian package;
1602: - SCALE is fixed and improved ("automatic" keyword);
1603: - PUTC and PUTR new intrinsics are added.
1604: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1605: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1606: VISIT does not find a name in level 1;
1607: - configure.in script is modified to add a new test (--enable-debug
1608: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1609: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1610: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1611: 'MATRIX' { 2 2 3 } GETR;
1612: - LOGSCALE intrinsic is improved and now, it can be used as
1613: { "main" "auxiliary" X Y } LOGSCALE;
1614: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1615: same than AXES:
1616: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1617: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1618: { { -10 10 } "automatic" } SCALE.
1619: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1620: because it changes only the dimension of the screen. To have a logarithmic
1621: scale, you must use LOGSCALE intrinsic:
1622: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1623: screen on second scale;
1624: - { X X } autoscale and { Y Y } logscale are now invalid;
1625: - *D is added (depth multiplication, for 3D graphics);
1626: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1627: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1628: - a major bug is fixed in GETI instrinsic when it is used with a name
1629: that contains a matrix or a vector (bad upper bounds conditions in
1630: incrementation);
1631: - DISP intrinsic now uses the 33-th flag. When it is not set
1632: (default), a final carriage return is sent to the terminal;
1633: - AXES intrinsic only takes a list that can contains the keywork
1634: "main" or "auxiliary". Before this modification, this keyword was in
1635: the first stack level;
1636: - vim syntax file is upgraded;
1637: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1638: option;
1639: - LAST is now disabled in the main loop of INT intrinsic;
1640: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1641: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1642: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1643: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1644: in 0);
1645: - LAST is disabled in the main loop of DRAW intrinsic;
1646: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1647: evaluation of an equation, the system stack is returned corrupted to the
1648: sequencer;
1649: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1650: of a loop are not integer or real.
1651: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1652: - the compilation stage aborts with an error message when two definitions
1653: have the same name. To improve the compilation() subroutine, I have to
1654: add some tests in gestion_variables.c;
1655: - recherche_type() subroutine ad some other connex subroutines are improved.
1656: Now, some syntax errors about object are caught and do not perform sequencer
1657: hangup;

1659: - Makefile.am's and configure.in scripts are improved.
1660: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1661: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1662: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1663: the boxwidth, 1 by default);
1664: - recherche_type() is rewritten to be faster;
1665: - gsl is upgraded (release 1.3);
1666: - ncurses is upgraded and patched (release 5.3);
1667: - recherche_instruction_suivante() is fixed (string research with included
1668: '"') and rewritten to be faster;
1669: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1670: segfault.
1671: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1679: - a minor bug is fixed in evaluation subroutine;
1680: - vim syntax file is improved;
1681: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1682: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1683: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1684: is a quick and dirty workaround...);
1685: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1686: - rplconvert is improved.
1687: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1794: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1795: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1796: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1797: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1798: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1799:
1800: Newton:[~/rpl/rpl] > time make install
1801: ...
1802: real 338m39.623s
1803: user 324m32.290s
