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

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

330: parent process was not interrupted if it is not group master process. To fix
331: this bug, SIGINJECT signal is not sent by child process but by control thread
332: in parent process;
333: - minor bug is fixed in data injection (POKE) that does not work as expected
334: when child process is protected by NRPROC.
335: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
336: - --enable-sysv-sems is added to configure script to use SystemV semaphores
337: functions instead of POSIX functions. This function is disabled or forced on
338: systems that does not provide correct POSIX or SysV semaphores subsystem;
339: - a dirty but not quick patch is written to workaround broken siginfo
340: structures. This patch has been successfully tested. It uses a segment of
341: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
342: (Unix PID);
343: - some OpenBSD's hacks are added;
344: - broken siginfo->si_pid field is now checked by configure script;
345: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

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

370: - BACKTRACE intrinsic is added;
371: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
372: when this structure is included in IFERR/THEN/END structure and when an error is
373: caught;
374: - major bug is fixed in analyse() subroutine. When evaluation() returned error
375: in a compiled program, analyse() caught this error twice and randomly aborted
376: with a segmentation error;
377: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
378: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
379: signals;
380: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
381: matrix.
382: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

406: process;
407: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
408: discovered in Solaris thread safe allocators (libmalloc and libumem) that

427: information about shared variable was not copied to new processus structure;
428: - some little memory leaks are fixed in evaluation(), recherche_type() and
429: sequenceur(). They only occured when syntax error were caught;
430: - IMPLICIT causes execution error instead system error;
431: - Hurd support is improved but currently broken because Hurd does not support
432: SIG_INFO. Work in progress;
433: - OpenBSD specific support is removed from sources;
434: - support for Mac OS X and Windows/Cygwin is added.
435: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

474: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
475: - in formatted file, string format returned a variable length string even if
476: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
477: a variable length string and 'CHARACTER*(n)' a fixed length string;
478: - keyed access files support is added. Currently, only formatted files are
479: supported;
480: - direct access files support is added. Currenlty, these files can only be used
481: in formatted mode;

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

528: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
529: signals sent to main process were not caught because DAEMON did not replace
530: old pid by new one;
531: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
532: evaluation when an error is reported from a subroutine in another subroutine.
533: For example, error was not caught in following program when it is executed with
534: -p option :

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

540: script file contains a multibyte character;
541: - IN intrinsic is added;
542: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
543: returned false ;
544: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
545: programs;
546: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
547: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

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

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

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

600: a freed semaphore and corrupts heap;
601: - CLRERR is added to erase previous errors;
602: - ERRN and ERRM return exception message and number;
603: - major bug is fixed in interruptions.c. All signal are now bufferised
604: when semaphore_liste_threads is null to avoid deadlock. This bug only
605: occured when STOP was sent to a dying thread or process (when this thread or
606: process was running retrait_thread());
607: - matrix rank is computed before matrix inversion;
608: - file locks are added to stdin and stdout. stderr is not locked because
609: all messages written by signal handlers are sent to stderr;

684: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
685: process is killed;
686: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
687: know typeof() intrinsic function. This function is not standard but exists
688: under Sun Studio, gcc, and maybe some others compilers. If this function does
689: not exist on your compiler, you can change its definition by old one in

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

752: that all programs that worked with old SQL intrinsic can now work with
753: SQLQUERY. With all new programs, you can open a real connection to databases;
754: - NRPROC is added. This new intrinsic is used to catch error from child
755: process. Without NRPROC, any errors returned by child process cause
756: main process to abort;
757: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
758: starts a new process). There are no mutexes in RPL/2 because all spawned process
759: use specific context. Nevertheless, shared variables and associated mutexes
760: should be added;

1110: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1111: versions of PROTECT and UNPROTECT that only deal with global variables
1112: (see RCL/SAVE);
1113: - variable management routines have been rewritten. The new ones are
1114: uncompatible with the old ones. Before these changes, a local variable

1519: - XCOL and YCOL are added;
1520: - a minor bug in analyse_syntaxique() is fixed;
1521: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1522: structure. ELSE is modified to return an error when ELSE appears in
1523: an ELSE/END structure;
1524: - a major bug is fixed in CYCLE;
1525: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1526: sequencer continues after the end of this loop;
1527: - SCLS is added;
1528: - DRWS now uses COLS to draw 2D graphics;
1529: - PPAR and SPAR are written. SPAR returns a list that contains the
1530: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1531: statistical variable, or "DISABLED" if its type is not one of the type of
1532: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1533: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1534: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1535: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1536: disabled. Arguments of EXTERNAL are case sensitive because the external
1537: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1538: of known external functions but add the new list to the last. { "all" }
1539: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1540: external names of the known functions;
1541: - mkrplso.in is modified.
1542: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1543: - vim syntax file is upgraded;
1544: - a minor mistake is fixed in recherche_instruction_suivante();
1545: - some minor memory leaks are fixed in recherche_type() function. They only
1546: occurs when a syntax error is detected;
1547: - #error and #warning preprocessor macros are added;
1548: - INCR and DECR are written (with integer or variable argument);
1549: - CSWP and RSWP are added and tested;
1550: - a minor bug is fixed in analyse.c;
1551: - DEBIAN/control is added to build debian package;
1552: - SCALE is fixed and improved ("automatic" keyword);
1553: - PUTC and PUTR new intrinsics are added.
1554: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1555: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1556: VISIT does not find a name in level 1;
1557: - configure.in script is modified to add a new test (--enable-debug
1558: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1559: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1560: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1561: 'MATRIX' { 2 2 3 } GETR;
1562: - LOGSCALE intrinsic is improved and now, it can be used as
1563: { "main" "auxiliary" X Y } LOGSCALE;
1564: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1565: same than AXES:
1566: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1567: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1568: { { -10 10 } "automatic" } SCALE.
1569: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1570: because it changes only the dimension of the screen. To have a logarithmic
1571: scale, you must use LOGSCALE intrinsic:
1572: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1573: screen on second scale;
1574: - { X X } autoscale and { Y Y } logscale are now invalid;
1575: - *D is added (depth multiplication, for 3D graphics);
1576: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1577: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1578: - a major bug is fixed in GETI instrinsic when it is used with a name
1579: that contains a matrix or a vector (bad upper bounds conditions in
1580: incrementation);
1581: - DISP intrinsic now uses the 33-th flag. When it is not set
1582: (default), a final carriage return is sent to the terminal;
1583: - AXES intrinsic only takes a list that can contains the keywork
1584: "main" or "auxiliary". Before this modification, this keyword was in
1585: the first stack level;
1586: - vim syntax file is upgraded;
1587: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1588: option;
1589: - LAST is now disabled in the main loop of INT intrinsic;
1590: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1591: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1592: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1593: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1594: in 0);
1595: - LAST is disabled in the main loop of DRAW intrinsic;
1596: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1597: evaluation of an equation, the system stack is returned corrupted to the
1598: sequencer;
1599: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1600: of a loop are not integer or real.
1601: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1602: - the compilation stage aborts with an error message when two definitions
1603: have the same name. To improve the compilation() subroutine, I have to
1604: add some tests in gestion_variables.c;
1605: - recherche_type() subroutine ad some other connex subroutines are improved.
1606: Now, some syntax errors about object are caught and do not perform sequencer
1607: hangup;
1608: - readline is upgraded (minor compilation bug with recent gcc);
1609: - Makefile.am's and configure.in scripts are improved.
1610: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1611: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1612: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1613: the boxwidth, 1 by default);
1614: - recherche_type() is rewritten to be faster;
1615: - gsl is upgraded (release 1.3);
1616: - ncurses is upgraded and patched (release 5.3);
1617: - recherche_instruction_suivante() is fixed (string research with included
1618: '"') and rewritten to be faster;
1619: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1620: segfault.
1621: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1629: - a minor bug is fixed in evaluation subroutine;
1630: - vim syntax file is improved;
1631: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1632: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1633: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1634: is a quick and dirty workaround...);
1635: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1636: - rplconvert is improved.
1637: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1653: Now, an expression such as 'A+' returns an error when it is analyzed;
1654: - VISIT intrinsic is added;
1655: - a major memory leak is fixed in evaluation.c. This bug rarely occurs in
1656: normal mode.

1744: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1745: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1746: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1747: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1748: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1749:
1750: Newton:[~/rpl/rpl] > time make install
