30: complex objects like expressions, lists or tables;
31: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
32: internal value was good but RPL/2 was not able to correctly display
33: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented

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

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

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

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

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

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

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

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

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

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

514: TEST2 << 0 inv >>
515: - major bug is fixed in variable management. Some local variables were
516: seen as global ones;

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

537: Indeed, conversion between different encodages requires transliteration
538: that is not offered by some iconv utility;
539: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
540: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

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

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

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

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

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

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

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

1088: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1089: versions of PROTECT and UNPROTECT that only deal with global variables
1090: (see RCL/SAVE);
1091: - variable management routines have been rewritten. The new ones are
1092: uncompatible with the old ones. Before these changes, a local variable
1093: was exported to a child subroutine, but cannot be modified into this

1517: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1518: external names of the known functions;
1519: - mkrplso.in is modified.
1520: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1521: - vim syntax file is upgraded;
1522: - a minor mistake is fixed in recherche_instruction_suivante();
1523: - some minor memory leaks are fixed in recherche_type() function. They only
1524: occurs when a syntax error is detected;
1525: - #error and #warning preprocessor macros are added;
1526: - INCR and DECR are written (with integer or variable argument);
1527: - CSWP and RSWP are added and tested;
1528: - a minor bug is fixed in analyse.c;
1529: - DEBIAN/control is added to build debian package;
1530: - SCALE is fixed and improved ("automatic" keyword);
1531: - PUTC and PUTR new intrinsics are added.
1532: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1533: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1534: VISIT does not find a name in level 1;
1535: - configure.in script is modified to add a new test (--enable-debug
1536: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1537: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1538: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1539: 'MATRIX' { 2 2 3 } GETR;
1540: - LOGSCALE intrinsic is improved and now, it can be used as
1541: { "main" "auxiliary" X Y } LOGSCALE;
1542: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1543: same than AXES:
1544: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1545: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1546: { { -10 10 } "automatic" } SCALE.
1547: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1548: because it changes only the dimension of the screen. To have a logarithmic
1549: scale, you must use LOGSCALE intrinsic:
1550: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1551: screen on second scale;
1552: - { X X } autoscale and { Y Y } logscale are now invalid;
1553: - *D is added (depth multiplication, for 3D graphics);
1554: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1555: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1556: - a major bug is fixed in GETI instrinsic when it is used with a name
1557: that contains a matrix or a vector (bad upper bounds conditions in
1558: incrementation);
1559: - DISP intrinsic now uses the 33-th flag. When it is not set
1560: (default), a final carriage return is sent to the terminal;
1561: - AXES intrinsic only takes a list that can contains the keywork
1562: "main" or "auxiliary". Before this modification, this keyword was in
1563: the first stack level;
1564: - vim syntax file is upgraded;
1565: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1566: option;
1567: - LAST is now disabled in the main loop of INT intrinsic;
1568: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1569: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1570: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1571: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1572: in 0);
1573: - LAST is disabled in the main loop of DRAW intrinsic;
1574: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1575: evaluation of an equation, the system stack is returned corrupted to the
1576: sequencer;
1577: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1578: of a loop are not integer or real.
1579: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1610: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1611: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1612: is a quick and dirty workaround...);
1613: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1614: - rplconvert is improved.
