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

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

370: parent process was not interrupted if it is not group master process. To fix
371: this bug, SIGINJECT signal is not sent by child process but by control thread
372: in parent process;
373: - minor bug is fixed in data injection (POKE) that does not work as expected
374: when child process is protected by NRPROC.
375: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
376: - --enable-sysv-sems is added to configure script to use SystemV semaphores
377: functions instead of POSIX functions. This function is disabled or forced on
378: systems that does not provide correct POSIX or SysV semaphores subsystem;
379: - a dirty but not quick patch is written to workaround broken siginfo
380: structures. This patch has been successfully tested. It uses a segment of

405: variable was created and when a local variable existed with the same name,
406: computed address of global variable was wrong;
407: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3

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

469: sequenceur(). They only occured when syntax error were caught;
470: - IMPLICIT causes execution error instead system error;
471: - Hurd support is improved but currently broken because Hurd does not support
472: SIG_INFO. Work in progress;
473: - OpenBSD specific support is removed from sources;
474: - support for Mac OS X and Windows/Cygwin is added.
475: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

515: - in formatted file, string format returned a variable length string even if
516: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
517: a variable length string and 'CHARACTER*(n)' a fixed length string;
518: - keyed access files support is added. Currently, only formatted files are
519: supported;
520: - direct access files support is added. Currenlty, these files can only be used
521: in formatted mode;

526: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
527: each execution (md5 and sha1 sums) to enhance security. If one of these tools
528: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
529: on a non recoverable system error;
530: - openssl and sqlite3 libraries are added;
531: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
532: variable indicates RPL/2 root directory. If it is not set, root path
533: is given by configure script (d_exec_path);
534: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

568: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
569: signals sent to main process were not caught because DAEMON did not replace
570: old pid by new one;
571: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
572: evaluation when an error is reported from a subroutine in another subroutine.
573: For example, error was not caught in following program when it is executed with

580: script file contains a multibyte character;
581: - IN intrinsic is added;
582: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
583: returned false ;

605: locales;
606: - '"' can now be used in strings ("\"");
607: - iconv is called with -c in preprocessor stage. It is done to write

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

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

772: - '->' intrinsic is improved. All object copies have been avoided;
773: - -n flag is added to catch HUP signal. stderr and stdout are redirected
774: to a file, stdin is redirected to /dev/null when control process is killed;
775: - a mutex is added to each object (before this modification,
776: RPL/2 used a global mutex and performances in multithreaded programs were very
777: poor.);
778: - ALARM is now interruptible;
779: - both PUT and PUTI intrinsics are improved and do not copy list and table
780: when nombre_occurrences == 1;

792: that all programs that worked with old SQL intrinsic can now work with
793: SQLQUERY. With all new programs, you can open a real connection to databases;
794: - NRPROC is added. This new intrinsic is used to catch error from child
795: process. Without NRPROC, any errors returned by child process cause
796: main process to abort;
797: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
798: starts a new process). There are no mutexes in RPL/2 because all spawned process
799: use specific context. Nevertheless, shared variables and associated mutexes
800: should be added;

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

949: - -p option is added. With this option, all scripts are compiled before
950: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
951: 40% faster;
952: - read and write operations in pipe() are rewritten to be sure that such
953: operations are atomic;
954: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1094: - HELP function is rewritten to be more friendly (a la OpenVMS);
1095: - external wrapper (rplplot) is written to force usage of gnuplot provided
1096: by RPL/2 if it is built during build process. If this build does not exist,
1097: it tries to launch regular gnuplot;
1098: - gnuplot is added to source tree to avoid some trouble between preinstalled
1099: gnuplot and release used by RPL/2. This addition to source tree is
1100: required by some incompatibility between gnuplot releases;

1106: not writable;
1107: - major regression is fixed in SYSEVAL intrinsic due to introduction of
1108: error scrutation.

1143: - configure.in script is added in lapack subtree;
1144: - VARS is modified to display variables status (LOCKED/UNLOCKED and
1145: STATIC/VOLATILE/PARAMETER/VARIABLE);
1146: - STATIC and VOLATILE intrinsics are added to specify static variables. A
1147: static variable can be transformed into volatile with VOLATILE.
1148: With STATIC, next variables created by '->' are static;
1149: - PROTECT and UNPROTECT are added to protect variables against write
1150: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1151: versions of PROTECT and UNPROTECT that only deal with global variables
1152: (see RCL/SAVE);
1153: - variable management routines have been rewritten. The new ones are
1154: uncompatible with the old ones. Before these changes, a local variable
1155: was exported to a child subroutine, but cannot be modified into this
1156: child subroutine. Now, a local variable is accessible only in its subroutine;
1157: - SAVE intrinsic is added to manipulate global variables;
1158: - SUSPEND is written. RPL/2 waits for a SIGCONT signal;
1159: - SORT, COL->, ->COL, ROW->, ROW-> intrinsics are written;

1534: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1535: - SLICESCALE intrinsic is added. Its syntax is
1536: { "automatic" nb_of_levels }
1537: { "discrete" l1 l2 l3 ... }
1538: { "incremental" start incr }
1539: { "incremental" start incr end }
1540: { "automatic" } (default);
1541: - a minor bug (in last stack) is fixed in AXES intrinsic
1542: - flag 52 is used to automatically update graphics;
1543: - man pages are updated;
1544: - evaluation() is modified to perform evaluation of expressions that contain
1545: '=';
1546: - a minor bug is fixed in AXES intrinsic;
1547: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1548: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1549: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1550: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1551: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1562: structure. ELSE is modified to return an error when ELSE appears in
1563: an ELSE/END structure;
1564: - a major bug is fixed in CYCLE;

1567: - SCLS is added;
1568: - DRWS now uses COLS to draw 2D graphics;
1569: - PPAR and SPAR are written. SPAR returns a list that contains the
1570: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1571: statistical variable, or "DISABLED" if its type is not one of the type of
1572: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1573: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1574: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1575: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1576: disabled. Arguments of EXTERNAL are case sensitive because the external
1577: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1578: of known external functions but add the new list to the last. { "all" }
1579: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1580: external names of the known functions;
1581: - mkrplso.in is modified.
1582: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1583: - vim syntax file is upgraded;
1584: - a minor mistake is fixed in recherche_instruction_suivante();
1585: - some minor memory leaks are fixed in recherche_type() function. They only
1586: occurs when a syntax error is detected;

1593: - PUTC and PUTR new intrinsics are added.
1594: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1595: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1596: VISIT does not find a name in level 1;
1597: - configure.in script is modified to add a new test (--enable-debug
1598: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1599: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1600: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1601: 'MATRIX' { 2 2 3 } GETR;
1602: - LOGSCALE intrinsic is improved and now, it can be used as
1603: { "main" "auxiliary" X Y } LOGSCALE;
1604: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1605: same than AXES:
1606: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1607: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1608: { { -10 10 } "automatic" } SCALE.
1609: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1610: because it changes only the dimension of the screen. To have a logarithmic
1611: scale, you must use LOGSCALE intrinsic:
1612: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1613: screen on second scale;
1614: - { X X } autoscale and { Y Y } logscale are now invalid;
1615: - *D is added (depth multiplication, for 3D graphics);
1616: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1617: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1618: - a major bug is fixed in GETI instrinsic when it is used with a name
1619: that contains a matrix or a vector (bad upper bounds conditions in
1620: incrementation);
1621: - DISP intrinsic now uses the 33-th flag. When it is not set
1622: (default), a final carriage return is sent to the terminal;
1623: - AXES intrinsic only takes a list that can contains the keywork
1624: "main" or "auxiliary". Before this modification, this keyword was in
1625: the first stack level;
1626: - vim syntax file is upgraded;
1627: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1628: option;
1629: - LAST is now disabled in the main loop of INT intrinsic;
1630: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1631: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1632: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1633: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1634: in 0);
1635: - LAST is disabled in the main loop of DRAW intrinsic;
1636: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1637: evaluation of an equation, the system stack is returned corrupted to the
1638: sequencer;
1639: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1640: of a loop are not integer or real.
1641: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1651: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1652: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1672: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1673: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1674: is a quick and dirty workaround...);
1675: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1676: - rplconvert is improved.

1786: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1787: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1788: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1789:
1790: Newton:[~/rpl/rpl] > time make install
