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

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

325: this bug, SIGINJECT signal is not sent by child process but by control thread
326: in parent process;
327: - minor bug is fixed in data injection (POKE) that does not work as expected
328: when child process is protected by NRPROC.
329: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
330: - --enable-sysv-sems is added to configure script to use SystemV semaphores
331: functions instead of POSIX functions. This function is disabled or forced on
332: systems that does not provide correct POSIX or SysV semaphores subsystem;
333: - a dirty but not quick patch is written to workaround broken siginfo
334: structures. This patch has been successfully tested. It uses a segment of
335: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
336: (Unix PID);
337: - some OpenBSD's hacks are added;
338: - broken siginfo->si_pid field is now checked by configure script;

357: a name of RPL/2 routine;
358: - major bug is fixed in global variable creation subroutine. When a global
359: variable was created and when a local variable existed with the same name,
360: computed address of global variable was wrong;
361: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
362: is forced in front of all libraries.

366: when this structure is included in IFERR/THEN/END structure and when an error is
367: caught;
368: - major bug is fixed in analyse() subroutine. When evaluation() returned error
369: in a compiled program, analyse() caught this error twice and randomly aborted
370: with a segmentation error;
371: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
372: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
373: signals;
374: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
375: matrix.

400: process;
401: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
402: discovered in Solaris thread safe allocators (libmalloc and libumem) that
403: are first fit class allocators. Solaris libmtmalloc works better and is
404: a best fit class allocator but its performance is poor than ptmalloc3
405: performance;
406: - major bug is fixed in ROW+ intrinsic (new row was not added where it
407: should);
408: - minor bugs are fixed in interruptions.c (semaphores values when error is
409: caught);
410: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process

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

468: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
469: - in formatted file, string format returned a variable length string even if
470: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
471: a variable length string and 'CHARACTER*(n)' a fixed length string;
472: - keyed access files support is added. Currently, only formatted files are
473: supported;
474: - direct access files support is added. Currenlty, these files can only be used
475: in formatted mode;
476: - virtual variables are now writte in UTF-8 and all special characters
477: in string are escaped;
478: - all formatted files are now converted into UTF-8;

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

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

534: script file contains a multibyte character;
535: - IN intrinsic is added;
536: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
537: returned false ;
538: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
539: programs;
540: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
541: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
542: strings were never closed;
543: - some bugs have been fixed in file management;

548: encountered at end of block, subroutine aborts with an execution error;
549: - major bug is fixed in OPEN (TCP/IPv4 sockets).
550: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
551: - DISP now locks stdout;
552: - rpliconv is added to replace standard iconv provided by operating system.
553: Indeed, conversion between different encodages requires transliteration
554: that is not offered by some iconv utility;
555: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
556: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

575: - pipe() is overwritten by a macro to avoid a system error. Communication
576: between process are done with pipes and these pipes are managed by a
577: specific asynchrone thread. If a script try to create more threads than
578: management thread can destroy, you can quickly achieve maximum number of
579: opened files and pipe() shall return a system error. This macro tries to create
580: pipes. If pipe() function returns an error, macro waits and retries. If
581: number of retries is greater than a hardcoded value, macro returns an error;
582: - major bug (deadlock) is fixed in process and thread management. I hope
583: this bug shall be the last one;
584: - major bug is fixed in DET intrinsic (determinant was computed without LU

593: was called before a pending interruption5 (SIGFSTOP), signal handler uses
594: a freed semaphore and corrupts heap;
595: - CLRERR is added to erase previous errors;
596: - ERRN and ERRM return exception message and number;
597: - major bug is fixed in interruptions.c. All signal are now bufferised
598: when semaphore_liste_threads is null to avoid deadlock. This bug only
599: occured when STOP was sent to a dying thread or process (when this thread or
600: process was running retrait_thread());
601: - matrix rank is computed before matrix inversion;
602: - file locks are added to stdin and stdout. stderr is not locked because
603: all messages written by signal handlers are sent to stderr;
604: - configure.in script is modified to test gcc version and avoid a bug in

678: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
679: process is killed;
680: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
681: know typeof() intrinsic function. This function is not standard but exists
682: under Sun Studio, gcc, and maybe some others compilers. If this function does
683: not exist on your compiler, you can change its definition by old one in

725: static variable that is shared by multiple threads;
726: - '->' intrinsic is improved. All object copies have been avoided;
727: - -n flag is added to catch HUP signal. stderr and stdout are redirected
728: to a file, stdin is redirected to /dev/null when control process is killed;

745: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
746: that all programs that worked with old SQL intrinsic can now work with
747: SQLQUERY. With all new programs, you can open a real connection to databases;
748: - NRPROC is added. This new intrinsic is used to catch error from child
749: process. Without NRPROC, any errors returned by child process cause
750: main process to abort;
751: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
752: starts a new process). There are no mutexes in RPL/2 because all spawned process
753: use specific context. Nevertheless, shared variables and associated mutexes
754: should be added;
755: - -D flag and DAEMONIZE intrinsic have been added;

1051: it tries to launch regular gnuplot;
1052: - gnuplot is added to source tree to avoid some trouble between preinstalled
1053: gnuplot and release used by RPL/2. This addition to source tree is

1103: - PROTECT and UNPROTECT are added to protect variables against write
1104: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1105: versions of PROTECT and UNPROTECT that only deal with global variables
1106: (see RCL/SAVE);
1107: - variable management routines have been rewritten. The new ones are
1108: uncompatible with the old ones. Before these changes, a local variable
1109: was exported to a child subroutine, but cannot be modified into this
1110: child subroutine. Now, a local variable is accessible only in its subroutine;

1148: multithreading. DETACH, SEND and RECV now use four real time signals to
1149: perform a better task synchronization;
1150: - some bugs introduced by locales specific compilations are fixed;
1151: - major memory corruption is fixed in DEPND;
1152: - HELP intrinsic is modified to print a classified output.

1523: - PPAR and SPAR are written. SPAR returns a list that contains the
1524: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1525: statistical variable, or "DISABLED" if its type is not one of the type of
1526: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1527: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1528: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1529: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1530: disabled. Arguments of EXTERNAL are case sensitive because the external
1531: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1532: of known external functions but add the new list to the last. { "all" }
1533: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1534: external names of the known functions;
1535: - mkrplso.in is modified.
1536: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1537: - vim syntax file is upgraded;
1538: - a minor mistake is fixed in recherche_instruction_suivante();
1539: - some minor memory leaks are fixed in recherche_type() function. They only
1540: occurs when a syntax error is detected;
1541: - #error and #warning preprocessor macros are added;
1542: - INCR and DECR are written (with integer or variable argument);
1543: - CSWP and RSWP are added and tested;
1544: - a minor bug is fixed in analyse.c;
1545: - DEBIAN/control is added to build debian package;
1546: - SCALE is fixed and improved ("automatic" keyword);
1547: - PUTC and PUTR new intrinsics are added.
1548: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1549: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1550: VISIT does not find a name in level 1;
1551: - configure.in script is modified to add a new test (--enable-debug
1552: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1553: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1554: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1555: 'MATRIX' { 2 2 3 } GETR;
1556: - LOGSCALE intrinsic is improved and now, it can be used as
1557: { "main" "auxiliary" X Y } LOGSCALE;
1558: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1559: same than AXES:
1560: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1561: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1562: { { -10 10 } "automatic" } SCALE.
1563: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1564: because it changes only the dimension of the screen. To have a logarithmic
1565: scale, you must use LOGSCALE intrinsic:
1566: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1567: screen on second scale;
1568: - { X X } autoscale and { Y Y } logscale are now invalid;
1569: - *D is added (depth multiplication, for 3D graphics);
1570: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1571: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1572: - a major bug is fixed in GETI instrinsic when it is used with a name
1573: that contains a matrix or a vector (bad upper bounds conditions in
1574: incrementation);
1575: - DISP intrinsic now uses the 33-th flag. When it is not set
1576: (default), a final carriage return is sent to the terminal;
1577: - AXES intrinsic only takes a list that can contains the keywork
1578: "main" or "auxiliary". Before this modification, this keyword was in
1579: the first stack level;
1580: - vim syntax file is upgraded;
1581: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1582: option;
1583: - LAST is now disabled in the main loop of INT intrinsic;
1584: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1585: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1586: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1587: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1588: in 0);
1589: - LAST is disabled in the main loop of DRAW intrinsic;
1590: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1591: evaluation of an equation, the system stack is returned corrupted to the
1592: sequencer;
1593: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1594: of a loop are not integer or real.
1595: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1603: - Makefile.am's and configure.in scripts are improved.
1604: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1605: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1606: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1624: - vim syntax file is improved;
1625: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1626: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1627: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1628: is a quick and dirty workaround...);
1629: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1630: - rplconvert is improved.
