24: to write data without precision loss. It can also be used to write
25: complex objects like expressions, lists or tables;
26: - major bug is fixed in formateur(). When INT64_MIN was pushed into stack,
27: internal value was good but RPL/2 was not able to correctly display
28: this value. This bug comes from ABS as ABS(INT64_MIN) cannot be represented
29: in integer. All abs(), fabs() and labs() present in source code have been
30: checked to avoid this kind of bug;

72: interrupt a loop from a subroutine within a compiled programm;
73: - workaround to avoid strange bug on slow network is written in READ
74: intrinsic;
75: - CRITICAL/END structure is added. When program enters in a critical
76: section, all other threads of the same process sleep until program leaves

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

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

303: parent process was not interrupted if it is not group master process. To fix
304: this bug, SIGINJECT signal is not sent by child process but by control thread
305: in parent process;
306: - minor bug is fixed in data injection (POKE) that does not work as expected
307: when child process is protected by NRPROC.
308: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
309: - --enable-sysv-sems is added to configure script to use SystemV semaphores
310: functions instead of POSIX functions. This function is disabled or forced on
311: systems that does not provide correct POSIX or SysV semaphores subsystem;
312: - a dirty but not quick patch is written to workaround broken siginfo
313: structures. This patch has been successfully tested. It uses a segment of
314: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
315: (Unix PID);
316: - some OpenBSD's hacks are added;
317: - broken siginfo->si_pid field is now checked by configure script;
318: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

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

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

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

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

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

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

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

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

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

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

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

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

572: was called before a pending interruption5 (SIGFSTOP), signal handler uses
573: a freed semaphore and corrupts heap;
574: - CLRERR is added to erase previous errors;
575: - ERRN and ERRM return exception message and number;
576: - major bug is fixed in interruptions.c. All signal are now bufferised
577: when semaphore_liste_threads is null to avoid deadlock. This bug only
578: occured when STOP was sent to a dying thread or process (when this thread or
579: process was running retrait_thread());
580: - matrix rank is computed before matrix inversion;
581: - file locks are added to stdin and stdout. stderr is not locked because
582: all messages written by signal handlers are sent to stderr;

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

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

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

1083: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1084: versions of PROTECT and UNPROTECT that only deal with global variables
1085: (see RCL/SAVE);
1086: - variable management routines have been rewritten. The new ones are
1087: uncompatible with the old ones. Before these changes, a local variable
1088: was exported to a child subroutine, but cannot be modified into this
1089: child subroutine. Now, a local variable is accessible only in its subroutine;

1519: occurs when a syntax error is detected;
1520: - #error and #warning preprocessor macros are added;
1521: - INCR and DECR are written (with integer or variable argument);
1522: - CSWP and RSWP are added and tested;
1523: - a minor bug is fixed in analyse.c;
1524: - DEBIAN/control is added to build debian package;

1527: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1528: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1529: VISIT does not find a name in level 1;
1530: - configure.in script is modified to add a new test (--enable-debug
1531: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1532: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1533: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1534: 'MATRIX' { 2 2 3 } GETR;
1535: - LOGSCALE intrinsic is improved and now, it can be used as
1536: { "main" "auxiliary" X Y } LOGSCALE;
1537: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1538: same than AXES:
1539: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1540: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1541: { { -10 10 } "automatic" } SCALE.
1542: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1543: because it changes only the dimension of the screen. To have a logarithmic
1544: scale, you must use LOGSCALE intrinsic:
1545: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1546: screen on second scale;
1547: - { X X } autoscale and { Y Y } logscale are now invalid;
1548: - *D is added (depth multiplication, for 3D graphics);
1549: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1550: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1551: - a major bug is fixed in GETI instrinsic when it is used with a name
1552: that contains a matrix or a vector (bad upper bounds conditions in
1553: incrementation);
1554: - DISP intrinsic now uses the 33-th flag. When it is not set
1555: (default), a final carriage return is sent to the terminal;
1556: - AXES intrinsic only takes a list that can contains the keywork
1557: "main" or "auxiliary". Before this modification, this keyword was in
1558: the first stack level;
1559: - vim syntax file is upgraded;
1560: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1561: option;
1562: - LAST is now disabled in the main loop of INT intrinsic;
1563: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.

1565: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1566: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1567: in 0);
1568: - LAST is disabled in the main loop of DRAW intrinsic;
1569: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1570: evaluation of an equation, the system stack is returned corrupted to the
1571: sequencer;
1572: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1573: of a loop are not integer or real.
1574: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1576: have the same name. To improve the compilation() subroutine, I have to
1577: add some tests in gestion_variables.c;
1578: - recherche_type() subroutine ad some other connex subroutines are improved.
1579: Now, some syntax errors about object are caught and do not perform sequencer

1584: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1585: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1602: - a minor bug is fixed in evaluation subroutine;
1603: - vim syntax file is improved;
1604: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1605: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1606: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1607: is a quick and dirty workaround...);
1608: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1609: - rplconvert is improved.
