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

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

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

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

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

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

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

406: information about shared variable was not copied to new processus structure;
407: - some little memory leaks are fixed in evaluation(), recherche_type() and
408: sequenceur(). They only occured when syntax error were caught;
409: - IMPLICIT causes execution error instead system error;
410: - Hurd support is improved but currently broken because Hurd does not support
411: SIG_INFO. Work in progress;
412: - OpenBSD specific support is removed from sources;
413: - support for Mac OS X and Windows/Cygwin is added.

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

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

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

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

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

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

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

584: occured when STOP was sent to a dying thread or process (when this thread or
585: process was running retrait_thread());
586: - matrix rank is computed before matrix inversion;
587: - file locks are added to stdin and stdout. stderr is not locked because
588: all messages written by signal handlers are sent to stderr;

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

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

1089: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1090: versions of PROTECT and UNPROTECT that only deal with global variables
1091: (see RCL/SAVE);
1092: - variable management routines have been rewritten. The new ones are
1093: uncompatible with the old ones. Before these changes, a local variable
1094: was exported to a child subroutine, but cannot be modified into this
1095: child subroutine. Now, a local variable is accessible only in its subroutine;

1518: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1519: external names of the known functions;
1520: - mkrplso.in is modified.
1521: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1522: - vim syntax file is upgraded;
1523: - a minor mistake is fixed in recherche_instruction_suivante();
1524: - some minor memory leaks are fixed in recherche_type() function. They only
1525: occurs when a syntax error is detected;
1526: - #error and #warning preprocessor macros are added;
1527: - INCR and DECR are written (with integer or variable argument);
1528: - CSWP and RSWP are added and tested;
1529: - a minor bug is fixed in analyse.c;
1530: - DEBIAN/control is added to build debian package;
1531: - SCALE is fixed and improved ("automatic" keyword);
1532: - PUTC and PUTR new intrinsics are added.
1533: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1534: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1535: VISIT does not find a name in level 1;
1536: - configure.in script is modified to add a new test (--enable-debug
1537: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1538: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1539: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1540: 'MATRIX' { 2 2 3 } GETR;
1541: - LOGSCALE intrinsic is improved and now, it can be used as
1542: { "main" "auxiliary" X Y } LOGSCALE;
1543: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1544: same than AXES:
1545: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1546: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1547: { { -10 10 } "automatic" } SCALE.
1548: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1549: because it changes only the dimension of the screen. To have a logarithmic
1550: scale, you must use LOGSCALE intrinsic:
1551: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1552: screen on second scale;
1553: - { X X } autoscale and { Y Y } logscale are now invalid;
1554: - *D is added (depth multiplication, for 3D graphics);
1555: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1556: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1557: - a major bug is fixed in GETI instrinsic when it is used with a name
1558: that contains a matrix or a vector (bad upper bounds conditions in
1559: incrementation);
1560: - DISP intrinsic now uses the 33-th flag. When it is not set
1561: (default), a final carriage return is sent to the terminal;
1562: - AXES intrinsic only takes a list that can contains the keywork
1563: "main" or "auxiliary". Before this modification, this keyword was in
1564: the first stack level;
1565: - vim syntax file is upgraded;
1566: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1567: option;
1568: - LAST is now disabled in the main loop of INT intrinsic;
1569: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1570: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1571: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1572: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1573: in 0);
1574: - LAST is disabled in the main loop of DRAW intrinsic;
1575: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1576: evaluation of an equation, the system stack is returned corrupted to the
1577: sequencer;
1578: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1579: of a loop are not integer or real.
1580: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1590: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1591: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1611: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1612: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1613: is a quick and dirty workaround...);
1614: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1615: - rplconvert is improved.
