28: to write data without precision loss. It can also be used to write
29: complex objects like expressions, lists or tables;
30: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
31: internal value was good but RPL/2 was not able to correctly display
32: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented

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

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

307: parent process was not interrupted if it is not group master process. To fix
308: this bug, SIGINJECT signal is not sent by child process but by control thread
309: in parent process;
310: - minor bug is fixed in data injection (POKE) that does not work as expected
311: when child process is protected by NRPROC.
312: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
313: - --enable-sysv-sems is added to configure script to use SystemV semaphores
314: functions instead of POSIX functions. This function is disabled or forced on
315: systems that does not provide correct POSIX or SysV semaphores subsystem;
316: - a dirty but not quick patch is written to workaround broken siginfo
317: structures. This patch has been successfully tested. It uses a segment of
318: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
319: (Unix PID);
320: - some OpenBSD's hacks are added;
321: - broken siginfo->si_pid field is now checked by configure script;

339: Level 0 and 1 variables adresses were swapped when a global variable masked
340: a name of RPL/2 routine;
341: - major bug is fixed in global variable creation subroutine. When a global
342: variable was created and when a local variable existed with the same name,
343: computed address of global variable was wrong;
344: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
345: is forced in front of all libraries.

347: - BACKTRACE intrinsic is added;
348: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
349: when this structure is included in IFERR/THEN/END structure and when an error is
350: caught;
351: - major bug is fixed in analyse() subroutine. When evaluation() returned error
352: in a compiled program, analyse() caught this error twice and randomly aborted
353: with a segmentation error;
354: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
355: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
356: signals;
357: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
358: matrix.

379: - PROCID is added;
380: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
381: and to not use swap;
382: - major bug is fixed in sql support. SQL connections were closed in all chield
383: process;
384: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
385: discovered in Solaris thread safe allocators (libmalloc and libumem) that
386: are first fit class allocators. Solaris libmtmalloc works better and is
387: a best fit class allocator but its performance is poor than ptmalloc3
388: performance;
389: - major bug is fixed in ROW+ intrinsic (new row was not added where it
390: should);
391: - minor bugs are fixed in interruptions.c (semaphores values when error is
392: caught);
393: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
394: created by SPAWN;
395: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
396: ATEXIT. If it receives SIGFABORT, it does not;
397: - ONEXIT is renamed in ATEXIT;
398: - ONEXIT new intrinsic is added.

400: - major bug is fixed in static and shared variables initialization subroutine.
401: This bug only occurs when RPL/2 tries to create a shared or static variable
402: from an expression;
403: - major bug is fixed in copie_etat_processus(). A field that contains
404: information about shared variable was not copied to new processus structure;
405: - some little memory leaks are fixed in evaluation(), recherche_type() and
406: sequenceur(). They only occured when syntax error were caught;
407: - IMPLICIT causes execution error instead system error;
408: - Hurd support is improved but currently broken because Hurd does not support
409: SIG_INFO. Work in progress;
410: - OpenBSD specific support is removed from sources;
411: - support for Mac OS X and Windows/Cygwin is added.

451: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
452: - in formatted file, string format returned a variable length string even if
453: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
454: a variable length string and 'CHARACTER*(n)' a fixed length string;
455: - keyed access files support is added. Currently, only formatted files are
456: supported;
457: - direct access files support is added. Currenlty, these files can only be used
458: in formatted mode;

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

504: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
505: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
506: signals sent to main process were not caught because DAEMON did not replace
507: old pid by new one;
508: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
509: evaluation when an error is reported from a subroutine in another subroutine.
510: For example, error was not caught in following program when it is executed with
511: -p option :
512: TEST << iferr TEST2 then end >>
513: TEST2 << 0 inv >>
514: - major bug is fixed in variable management. Some local variables were
515: seen as global ones;

517: script file contains a multibyte character;
518: - IN intrinsic is added;
519: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
520: returned false ;
521: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
522: programs;
523: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
524: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

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

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

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

577: a freed semaphore and corrupts heap;
578: - CLRERR is added to erase previous errors;
579: - ERRN and ERRM return exception message and number;
580: - major bug is fixed in interruptions.c. All signal are now bufferised
581: when semaphore_liste_threads is null to avoid deadlock. This bug only
582: occured when STOP was sent to a dying thread or process (when this thread or
583: process was running retrait_thread());
584: - matrix rank is computed before matrix inversion;
585: - file locks are added to stdin and stdout. stderr is not locked because
586: all messages written by signal handlers are sent to stderr;

661: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
662: process is killed;
663: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
664: know typeof() intrinsic function. This function is not standard but exists
665: under Sun Studio, gcc, and maybe some others compilers. If this function does

729: that all programs that worked with old SQL intrinsic can now work with
730: SQLQUERY. With all new programs, you can open a real connection to databases;
731: - NRPROC is added. This new intrinsic is used to catch error from child
732: process. Without NRPROC, any errors returned by child process cause
733: main process to abort;
734: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
735: starts a new process). There are no mutexes in RPL/2 because all spawned process
736: use specific context. Nevertheless, shared variables and associated mutexes
737: should be added;

881: without this option !
882: - new garbage collector (and more efficient) is written;
883: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
884: not support real time signals, RPL/2 cannot use multitasking functions;

1087: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1088: versions of PROTECT and UNPROTECT that only deal with global variables
1089: (see RCL/SAVE);
1090: - variable management routines have been rewritten. The new ones are
1091: uncompatible with the old ones. Before these changes, a local variable
1092: was exported to a child subroutine, but cannot be modified into this

1521: - a minor mistake is fixed in recherche_instruction_suivante();
1522: - some minor memory leaks are fixed in recherche_type() function. They only
1523: occurs when a syntax error is detected;
1524: - #error and #warning preprocessor macros are added;
1525: - INCR and DECR are written (with integer or variable argument);
1526: - CSWP and RSWP are added and tested;
1527: - a minor bug is fixed in analyse.c;
1528: - DEBIAN/control is added to build debian package;
1529: - SCALE is fixed and improved ("automatic" keyword);
1530: - PUTC and PUTR new intrinsics are added.
1531: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1532: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1533: VISIT does not find a name in level 1;
1534: - configure.in script is modified to add a new test (--enable-debug
1535: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1536: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1537: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1538: 'MATRIX' { 2 2 3 } GETR;
1539: - LOGSCALE intrinsic is improved and now, it can be used as
1540: { "main" "auxiliary" X Y } LOGSCALE;
1541: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1542: same than AXES:
1543: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1544: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1545: { { -10 10 } "automatic" } SCALE.
1546: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1547: because it changes only the dimension of the screen. To have a logarithmic
1548: scale, you must use LOGSCALE intrinsic:
1549: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1550: screen on second scale;
1551: - { X X } autoscale and { Y Y } logscale are now invalid;
1552: - *D is added (depth multiplication, for 3D graphics);
1553: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1554: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1555: - a major bug is fixed in GETI instrinsic when it is used with a name
1556: that contains a matrix or a vector (bad upper bounds conditions in
1557: incrementation);
1558: - DISP intrinsic now uses the 33-th flag. When it is not set
1559: (default), a final carriage return is sent to the terminal;
1560: - AXES intrinsic only takes a list that can contains the keywork
1561: "main" or "auxiliary". Before this modification, this keyword was in
1562: the first stack level;
1563: - vim syntax file is upgraded;
1564: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1565: option;
1566: - LAST is now disabled in the main loop of INT intrinsic;
1567: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1568: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1569: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1570: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1571: in 0);
1572: - LAST is disabled in the main loop of DRAW intrinsic;
1573: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1574: evaluation of an equation, the system stack is returned corrupted to the
1575: sequencer;
1576: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1577: of a loop are not integer or real.
1578: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1579: - the compilation stage aborts with an error message when two definitions
1580: have the same name. To improve the compilation() subroutine, I have to
1581: add some tests in gestion_variables.c;
1582: - recherche_type() subroutine ad some other connex subroutines are improved.
1583: Now, some syntax errors about object are caught and do not perform sequencer
1584: hangup;

1586: - Makefile.am's and configure.in scripts are improved.
1587: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1588: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1589: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1606: - a minor bug is fixed in evaluation subroutine;
1607: - vim syntax file is improved;
1608: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1609: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1610: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1611: is a quick and dirty workaround...);
1612: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1613: - rplconvert is improved.
