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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

659: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
660: process is killed;
661: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
662: know typeof() intrinsic function. This function is not standard but exists

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

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

1085: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1086: versions of PROTECT and UNPROTECT that only deal with global variables
1087: (see RCL/SAVE);
1088: - variable management routines have been rewritten. The new ones are
1089: uncompatible with the old ones. Before these changes, a local variable
1090: was exported to a child subroutine, but cannot be modified into this
1091: child subroutine. Now, a local variable is accessible only in its subroutine;

1521: occurs when a syntax error is detected;
1522: - #error and #warning preprocessor macros are added;
1523: - INCR and DECR are written (with integer or variable argument);
1524: - CSWP and RSWP are added and tested;
1525: - a minor bug is fixed in analyse.c;
1526: - DEBIAN/control is added to build debian package;

1529: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1530: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1531: VISIT does not find a name in level 1;
1532: - configure.in script is modified to add a new test (--enable-debug
1533: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1534: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1535: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1536: 'MATRIX' { 2 2 3 } GETR;
1537: - LOGSCALE intrinsic is improved and now, it can be used as
1538: { "main" "auxiliary" X Y } LOGSCALE;
1539: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1540: same than AXES:
1541: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1542: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1543: { { -10 10 } "automatic" } SCALE.
1544: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1545: because it changes only the dimension of the screen. To have a logarithmic
1546: scale, you must use LOGSCALE intrinsic:
1547: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1548: screen on second scale;
1549: - { X X } autoscale and { Y Y } logscale are now invalid;
1550: - *D is added (depth multiplication, for 3D graphics);
1551: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1552: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1553: - a major bug is fixed in GETI instrinsic when it is used with a name
1554: that contains a matrix or a vector (bad upper bounds conditions in
1555: incrementation);
1556: - DISP intrinsic now uses the 33-th flag. When it is not set
1557: (default), a final carriage return is sent to the terminal;
1558: - AXES intrinsic only takes a list that can contains the keywork
1559: "main" or "auxiliary". Before this modification, this keyword was in
1560: the first stack level;
1561: - vim syntax file is upgraded;
1562: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1563: option;
1564: - LAST is now disabled in the main loop of INT intrinsic;
1565: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.

1567: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1568: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1569: in 0);
1570: - LAST is disabled in the main loop of DRAW intrinsic;
1571: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1572: evaluation of an equation, the system stack is returned corrupted to the
1573: sequencer;
1574: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1575: of a loop are not integer or real.
1576: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1578: have the same name. To improve the compilation() subroutine, I have to
1579: add some tests in gestion_variables.c;
1580: - recherche_type() subroutine ad some other connex subroutines are improved.
1581: Now, some syntax errors about object are caught and do not perform sequencer

1586: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1587: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1605: - vim syntax file is improved;
1606: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1607: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1608: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1609: is a quick and dirty workaround...);
1610: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1611: - rplconvert is improved.
