7: to called definitions.
8: * Mon Apr 1 2013 BERTRAND Joël <rpl@systella.fr> rpl-4.1.13 (RPL/2)
9: - integer overflows have been fixed (NEG, ABS, minus);
10: - global variables can now be recalled from ATEXIT procedure;
11: - ATEXIT registered procedure is now executed even if program is stopped by
12: SIGINT;
13: - minor bug is fixed in TOKENIZE intrinsic instruction. TOKENIZE did not work on
14: a copy of input string;
15: - major bug (segfault) is fixed in liste_variables(). It only occurs
16: when this function is called with shared variables;
17: - all internal data are now stored in 64 bits wide integers (even is 32 bits
18: ABI is selected);
19: - major bug is fixed in recherche_instruction_suivante(). In some

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

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

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

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

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

333: Level 0 and 1 variables adresses were swapped when a global variable masked
334: a name of RPL/2 routine;
335: - major bug is fixed in global variable creation subroutine. When a global
336: variable was created and when a local variable existed with the same name,
337: computed address of global variable was wrong;
338: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
339: is forced in front of all libraries.
340: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
341: - BACKTRACE intrinsic is added;
342: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
343: when this structure is included in IFERR/THEN/END structure and when an error is
344: caught;
345: - major bug is fixed in analyse() subroutine. When evaluation() returned error
346: in a compiled program, analyse() caught this error twice and randomly aborted
347: with a segmentation error;
348: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
349: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
350: signals;
351: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
352: matrix.
353: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
354: - minor bug is fixed in evaluation() subroutine. With this patch, same program
355: returns same result with or without -p flag;

357: - openssl is upgraded to 1.0.0a;
358: - interrupt stacks are now FIFO instead of LIFO;
359: - debug memory allocation subroutines are improved to run in multithreaded
360: programs;
361: - some memory leaks are fixed in process management (SPAWN and DETACH);
362: - version verification is added to shared objects;
363: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
364: linux (false mremap() prototype);
365: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
366: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
367: - all '-' are replaced by '_' in random generator list;

370: - major bug is fixed in copie_objet() and liberation(). Only concerns
371: format in FCH (file descriptor) and SCK (socket descriptor);
372: - debug routines are improved;
373: - PROCID is added;
374: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
375: and to not use swap;
376: - major bug is fixed in sql support. SQL connections were closed in all chield
377: process;
378: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
379: discovered in Solaris thread safe allocators (libmalloc and libumem) that

457: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
458: each execution (md5 and sha1 sums) to enhance security. If one of these tools
459: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
460: on a non recoverable system error;
461: - openssl and sqlite3 libraries are added;
462: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
463: variable indicates RPL/2 root directory. If it is not set, root path

499: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
500: signals sent to main process were not caught because DAEMON did not replace
501: old pid by new one;
502: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
503: evaluation when an error is reported from a subroutine in another subroutine.
504: For example, error was not caught in following program when it is executed with

511: script file contains a multibyte character;
512: - IN intrinsic is added;
513: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
514: returned false ;
515: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
516: programs;
517: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;

536: locales;
537: - '"' can now be used in strings ("\"");
538: - iconv is called with -c in preprocessor stage. It is done to write

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

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

577: process was running retrait_thread());
578: - matrix rank is computed before matrix inversion;
579: - file locks are added to stdin and stdout. stderr is not locked because
580: all messages written by signal handlers are sent to stderr;

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

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

872: - as old file program was bugged, a new option is added to configure script.
873: When configure is called with --disable-encoding-autodetection, make does not
874: try to detect source encoding. Please, do not use if RPL/2 can be built
875: without this option !
876: - new garbage collector (and more efficient) is written;

880: - -p option is added. With this option, all scripts are compiled before
881: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
882: 40% faster;
883: - read and write operations in pipe() are rewritten to be sure that such
884: operations are atomic;
885: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1081: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1082: versions of PROTECT and UNPROTECT that only deal with global variables
1083: (see RCL/SAVE);
1084: - variable management routines have been rewritten. The new ones are
1085: uncompatible with the old ones. Before these changes, a local variable
1086: was exported to a child subroutine, but cannot be modified into this
1087: child subroutine. Now, a local variable is accessible only in its subroutine;

1125: multithreading. DETACH, SEND and RECV now use four real time signals to
1126: perform a better task synchronization;
1127: - some bugs introduced by locales specific compilations are fixed;
1128: - major memory corruption is fixed in DEPND;
1129: - HELP intrinsic is modified to print a classified output.

1520: - CSWP and RSWP are added and tested;
1521: - a minor bug is fixed in analyse.c;
1522: - DEBIAN/control is added to build debian package;
1523: - SCALE is fixed and improved ("automatic" keyword);
1524: - PUTC and PUTR new intrinsics are added.
1525: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1526: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1527: VISIT does not find a name in level 1;
1528: - configure.in script is modified to add a new test (--enable-debug
1529: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1530: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1531: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1532: 'MATRIX' { 2 2 3 } GETR;
1533: - LOGSCALE intrinsic is improved and now, it can be used as
1534: { "main" "auxiliary" X Y } LOGSCALE;
1535: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1536: same than AXES:
1537: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1538: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1539: { { -10 10 } "automatic" } SCALE.
1540: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1541: because it changes only the dimension of the screen. To have a logarithmic
1542: scale, you must use LOGSCALE intrinsic:
1543: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1544: screen on second scale;
1545: - { X X } autoscale and { Y Y } logscale are now invalid;
1546: - *D is added (depth multiplication, for 3D graphics);
1547: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1548: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1549: - a major bug is fixed in GETI instrinsic when it is used with a name
1550: that contains a matrix or a vector (bad upper bounds conditions in
1551: incrementation);
1552: - DISP intrinsic now uses the 33-th flag. When it is not set
1553: (default), a final carriage return is sent to the terminal;
1554: - AXES intrinsic only takes a list that can contains the keywork
1555: "main" or "auxiliary". Before this modification, this keyword was in
1556: the first stack level;
1557: - vim syntax file is upgraded;
1558: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1559: option;
1560: - LAST is now disabled in the main loop of INT intrinsic;
1561: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1562: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1563: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1564: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1565: in 0);
1566: - LAST is disabled in the main loop of DRAW intrinsic;
1567: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1568: evaluation of an equation, the system stack is returned corrupted to the
1569: sequencer;
1570: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1571: of a loop are not integer or real.
1572: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1573: - the compilation stage aborts with an error message when two definitions
1574: have the same name. To improve the compilation() subroutine, I have to
1575: add some tests in gestion_variables.c;
1576: - recherche_type() subroutine ad some other connex subroutines are improved.
1577: Now, some syntax errors about object are caught and do not perform sequencer
1578: hangup;

1580: - Makefile.am's and configure.in scripts are improved.
1581: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1582: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1583: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1584: the boxwidth, 1 by default);
1585: - recherche_type() is rewritten to be faster;
1586: - gsl is upgraded (release 1.3);
1587: - ncurses is upgraded and patched (release 5.3);
1588: - recherche_instruction_suivante() is fixed (string research with included
1589: '"') and rewritten to be faster;

1600: - a minor bug is fixed in evaluation subroutine;
1601: - vim syntax file is improved;
1602: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1603: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1604: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1605: is a quick and dirty workaround...);
1606: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1607: - rplconvert is improved.
1608: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
