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

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

336: parent process was not interrupted if it is not group master process. To fix
337: this bug, SIGINJECT signal is not sent by child process but by control thread
338: in parent process;
339: - minor bug is fixed in data injection (POKE) that does not work as expected
340: when child process is protected by NRPROC.
341: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
342: - --enable-sysv-sems is added to configure script to use SystemV semaphores
343: functions instead of POSIX functions. This function is disabled or forced on
344: systems that does not provide correct POSIX or SysV semaphores subsystem;
345: - a dirty but not quick patch is written to workaround broken siginfo
346: structures. This patch has been successfully tested. It uses a segment of
347: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
348: (Unix PID);
349: - some OpenBSD's hacks are added;
350: - broken siginfo->si_pid field is now checked by configure script;

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

378: when this structure is included in IFERR/THEN/END structure and when an error is
379: caught;
380: - major bug is fixed in analyse() subroutine. When evaluation() returned error
381: in a compiled program, analyse() caught this error twice and randomly aborted
382: with a segmentation error;
383: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
384: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
385: signals;

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

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

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

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

534: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
535: signals sent to main process were not caught because DAEMON did not replace
536: old pid by new one;
537: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
538: evaluation when an error is reported from a subroutine in another subroutine.
539: For example, error was not caught in following program when it is executed with
540: -p option :
541: TEST << iferr TEST2 then end >>
542: TEST2 << 0 inv >>
543: - major bug is fixed in variable management. Some local variables were
544: seen as global ones;

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

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

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

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

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

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

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

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

1063: it tries to launch regular gnuplot;
1064: - gnuplot is added to source tree to avoid some trouble between preinstalled
1065: gnuplot and release used by RPL/2. This addition to source tree is

1114: With STATIC, next variables created by '->' are static;
1115: - PROTECT and UNPROTECT are added to protect variables against write
1116: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1117: versions of PROTECT and UNPROTECT that only deal with global variables
1118: (see RCL/SAVE);
1119: - variable management routines have been rewritten. The new ones are
1120: uncompatible with the old ones. Before these changes, a local variable
1121: was exported to a child subroutine, but cannot be modified into this
1122: child subroutine. Now, a local variable is accessible only in its subroutine;
1123: - SAVE intrinsic is added to manipulate global variables;

1523: * Sun May 4 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6i (RPL/2)
1524: - '=' is added and tested;
1525: - XCOL and YCOL are added;
1526: - a minor bug in analyse_syntaxique() is fixed;
1527: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1528: structure. ELSE is modified to return an error when ELSE appears in
1529: an ELSE/END structure;
1530: - a major bug is fixed in CYCLE;
1531: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1532: sequencer continues after the end of this loop;
1533: - SCLS is added;
1534: - DRWS now uses COLS to draw 2D graphics;
1535: - PPAR and SPAR are written. SPAR returns a list that contains the
1536: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1537: statistical variable, or "DISABLED" if its type is not one of the type of
1538: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1539: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1540: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1541: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1542: disabled. Arguments of EXTERNAL are case sensitive because the external
1543: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1544: of known external functions but add the new list to the last. { "all" }
1545: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1546: external names of the known functions;
1547: - mkrplso.in is modified.
1548: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1549: - vim syntax file is upgraded;
1550: - a minor mistake is fixed in recherche_instruction_suivante();
1551: - some minor memory leaks are fixed in recherche_type() function. They only
1552: occurs when a syntax error is detected;
1553: - #error and #warning preprocessor macros are added;
1554: - INCR and DECR are written (with integer or variable argument);
1555: - CSWP and RSWP are added and tested;
1556: - a minor bug is fixed in analyse.c;
1557: - DEBIAN/control is added to build debian package;
1558: - SCALE is fixed and improved ("automatic" keyword);
1559: - PUTC and PUTR new intrinsics are added.
1560: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1561: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1562: VISIT does not find a name in level 1;
1563: - configure.in script is modified to add a new test (--enable-debug
1564: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1565: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1566: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1567: 'MATRIX' { 2 2 3 } GETR;
1568: - LOGSCALE intrinsic is improved and now, it can be used as
1569: { "main" "auxiliary" X Y } LOGSCALE;
1570: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1571: same than AXES:
1572: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1573: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1574: { { -10 10 } "automatic" } SCALE.
1575: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1576: because it changes only the dimension of the screen. To have a logarithmic
1577: scale, you must use LOGSCALE intrinsic:
1578: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1579: screen on second scale;
1580: - { X X } autoscale and { Y Y } logscale are now invalid;
1581: - *D is added (depth multiplication, for 3D graphics);
1582: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1583: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1584: - a major bug is fixed in GETI instrinsic when it is used with a name
1585: that contains a matrix or a vector (bad upper bounds conditions in
1586: incrementation);
1587: - DISP intrinsic now uses the 33-th flag. When it is not set
1588: (default), a final carriage return is sent to the terminal;
1589: - AXES intrinsic only takes a list that can contains the keywork
1590: "main" or "auxiliary". Before this modification, this keyword was in
1591: the first stack level;
1592: - vim syntax file is upgraded;
1593: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1594: option;
1595: - LAST is now disabled in the main loop of INT intrinsic;
1596: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1597: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1598: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1599: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1600: in 0);
1601: - LAST is disabled in the main loop of DRAW intrinsic;
1602: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1603: evaluation of an equation, the system stack is returned corrupted to the
1604: sequencer;
1605: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1606: of a loop are not integer or real.
1607: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1608: - the compilation stage aborts with an error message when two definitions
1609: have the same name. To improve the compilation() subroutine, I have to
1610: add some tests in gestion_variables.c;
1611: - recherche_type() subroutine ad some other connex subroutines are improved.
1612: Now, some syntax errors about object are caught and do not perform sequencer
1613: hangup;
1614: - readline is upgraded (minor compilation bug with recent gcc);
1615: - Makefile.am's and configure.in scripts are improved.
1616: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1617: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1618: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1619: the boxwidth, 1 by default);
1620: - recherche_type() is rewritten to be faster;
1621: - gsl is upgraded (release 1.3);
1622: - ncurses is upgraded and patched (release 5.3);
1623: - recherche_instruction_suivante() is fixed (string research with included
1624: '"') and rewritten to be faster;
1625: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1626: segfault.
1627: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1635: - a minor bug is fixed in evaluation subroutine;
1636: - vim syntax file is improved;
1637: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1638: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1639: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1640: is a quick and dirty workaround...);
1641: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1642: - rplconvert is improved.
1643: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1752: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1753: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1754: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1755:
1756: Newton:[~/rpl/rpl] > time make install
1757: ...
1758: real 338m39.623s
1759: user 324m32.290s
