400: - New variable management is written. Please note that -p flag does not work
401: and all multithread/multitask capabilities have been disabled until this
402: new subsystem shall be validated.
403: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
404: - major bug is fixed in STD format (1E7 sq prints 1);
405: - major bug is fixed in READ intrinsic (socket). This bug was introduced
406: by a new feature in glibc.
407: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
408: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
409: "ALL" IMPLICIT when it runs in interactive mode;
410: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
411: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
412: to use SAVE to manipulate global variables;
413: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
414: subroutines;
415: - fix major memory access violation in evaluation subroutine. Only occurs
416: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
417: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
418: when X was a vector or a table.
419: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)

448: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
449: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
450: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
451: corruption. As internal memory management have been improved, a best fit
452: allocator like ptmalloc3 is not required anymore;
453: - gnuplot is upgraded to 4.4.1;
454: - deadlock is fixed in signal handlers: same mutex was used in standard
455: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
456: and signal handlers. A new signal handler specific mutex is added;
457: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
458: that has to be evaluated by ->NUM;
459: - rplfile build process is modify to be sure that rplfile is not modified
460: after rpl build stage (to be sure that rplfile checksum is not modified after

465: ABORT now works on eComStation;
466: - sqlite is upgraded to 3.7.2;
467: - bug is fixed in software interrupts. When both process have different PID,
468: parent process was not interrupted if it is not group master process. To fix
469: this bug, SIGINJECT signal is not sent by child process but by control thread
470: in parent process;
471: - minor bug is fixed in data injection (POKE) that does not work as expected
472: when child process is protected by NRPROC.
473: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
474: - --enable-sysv-sems is added to configure script to use SystemV semaphores
475: functions instead of POSIX functions. This function is disabled or forced on
476: systems that does not provide correct POSIX or SysV semaphores subsystem;
477: - a dirty but not quick patch is written to workaround broken siginfo
478: structures. This patch has been successfully tested. It uses a segment of
479: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
480: (Unix PID);
481: - some OpenBSD's hacks are added;
482: - broken siginfo->si_pid field is now checked by configure script;
483: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

497: - sqlite is upgraded to 3.7.0.1;
498: - units is upgraded to 1.88;
499: - another major bug is fixed in the same variable creation subroutine.
500: Level 0 and 1 variables adresses were swapped when a global variable masked
501: a name of RPL/2 routine;
502: - major bug is fixed in global variable creation subroutine. When a global
503: variable was created and when a local variable existed with the same name,
504: computed address of global variable was wrong;
505: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
506: is forced in front of all libraries.
507: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
508: - BACKTRACE intrinsic is added;
509: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
510: when this structure is included in IFERR/THEN/END structure and when an error is
511: caught;
512: - major bug is fixed in analyse() subroutine. When evaluation() returned error
513: in a compiled program, analyse() caught this error twice and randomly aborted
514: with a segmentation error;
515: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
516: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
517: signals;
518: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
519: matrix.
520: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

538: format in FCH (file descriptor) and SCK (socket descriptor);
539: - debug routines are improved;
540: - PROCID is added;
541: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
542: and to not use swap;
543: - major bug is fixed in sql support. SQL connections were closed in all chield
544: process;
545: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
546: discovered in Solaris thread safe allocators (libmalloc and libumem) that
547: are first fit class allocators. Solaris libmtmalloc works better and is
548: a best fit class allocator but its performance is poor than ptmalloc3
549: performance;
550: - major bug is fixed in ROW+ intrinsic (new row was not added where it
551: should);
552: - minor bugs are fixed in interruptions.c (semaphores values when error is
553: caught);
554: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
555: created by SPAWN;
556: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
557: ATEXIT. If it receives SIGFABORT, it does not;
558: - ONEXIT is renamed in ATEXIT;

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

615: a variable length string and 'CHARACTER*(n)' a fixed length string;
616: - keyed access files support is added. Currently, only formatted files are
617: supported;
618: - direct access files support is added. Currenlty, these files can only be used
619: in formatted mode;
620: - virtual variables are now writte in UTF-8 and all special characters
621: in string are escaped;
622: - all formatted files are now converted into UTF-8;
623: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
624: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
625: each execution (md5 and sha1 sums) to enhance security. If one of these tools
626: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
627: on a non recoverable system error;
628: - openssl and sqlite3 libraries are added;
629: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
630: variable indicates RPL/2 root directory. If it is not set, root path
631: is given by configure script (d_exec_path);
632: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

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

689: - major bug is fixed in -A command line option (NULL character is missing);
690: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
691: made by blocks (1024 bytes). When an incomplete multibyte sequence is

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

702: - fprintf is replaced by some functions that allow transliterations between
703: locales;
704: - '"' can now be used in strings ("\"");
705: - iconv is called with -c in preprocessor stage. It is done to write
706: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
707: - double free is fixed in liberation() (type SQL, only occurs when locale is
708: set);
709: - LOCALIZATION, UCASE and LCASE are added;

713: used in onLoading from shared library, USE was pushed on stack as algebraic
714: expression;
715: - libiconv is upgraded to 1.13.1;
716: - gnuplot is upgraded to 4.2.6;

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

735: or thread number;
736: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
737: was called before a pending interruption5 (SIGFSTOP), signal handler uses
738: a freed semaphore and corrupts heap;
739: - CLRERR is added to erase previous errors;
740: - ERRN and ERRM return exception message and number;
741: - major bug is fixed in interruptions.c. All signal are now bufferised
742: when semaphore_liste_threads is null to avoid deadlock. This bug only
743: occured when STOP was sent to a dying thread or process (when this thread or
744: process was running retrait_thread());
745: - matrix rank is computed before matrix inversion;
746: - file locks are added to stdin and stdout. stderr is not locked because
747: all messages written by signal handlers are sent to stderr;
748: - configure.in script is modified to test gcc version and avoid a bug in

822: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
823: process is killed;
824: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
825: know typeof() intrinsic function. This function is not standard but exists
826: under Sun Studio, gcc, and maybe some others compilers. If this function does
827: not exist on your compiler, you can change its definition by old one in
828: src/rpl.h;

891: SQLQUERY. With all new programs, you can open a real connection to databases;
892: - NRPROC is added. This new intrinsic is used to catch error from child
893: process. Without NRPROC, any errors returned by child process cause
894: main process to abort;
895: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
896: starts a new process). There are no mutexes in RPL/2 because all spawned process
897: use specific context. Nevertheless, shared variables and associated mutexes
898: should be added;

1193: - external wrapper (rplplot) is written to force usage of gnuplot provided
1194: by RPL/2 if it is built during build process. If this build does not exist,
1195: it tries to launch regular gnuplot;
1196: - gnuplot is added to source tree to avoid some trouble between preinstalled
1197: gnuplot and release used by RPL/2. This addition to source tree is
1198: required by some incompatibility between gnuplot releases;

1576: fine...);
1577: - NOT is not correctly formatted in formateur.c:
1578: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1579: with a NOTZ function !
1580: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1581: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1583: - RPL/2 is tested with efence and valgrind;
1584: - configure.in script is modified;
1585: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1665: - SCLS is added;
1666: - DRWS now uses COLS to draw 2D graphics;
1667: - PPAR and SPAR are written. SPAR returns a list that contains the
1668: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1669: statistical variable, or "DISABLED" if its type is not one of the type of
1670: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1671: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1672: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1673: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1674: disabled. Arguments of EXTERNAL are case sensitive because the external
1675: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1676: of known external functions but add the new list to the last. { "all" }
1677: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1678: external names of the known functions;
1679: - mkrplso.in is modified.
1680: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1681: - vim syntax file is upgraded;
1682: - a minor mistake is fixed in recherche_instruction_suivante();
1683: - some minor memory leaks are fixed in recherche_type() function. They only

1692: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1693: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1694: VISIT does not find a name in level 1;
1695: - configure.in script is modified to add a new test (--enable-debug
1696: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1697: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1698: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1699: 'MATRIX' { 2 2 3 } GETR;
1700: - LOGSCALE intrinsic is improved and now, it can be used as
1701: { "main" "auxiliary" X Y } LOGSCALE;
1702: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1703: same than AXES:
1704: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1705: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1706: { { -10 10 } "automatic" } SCALE.
1707: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1708: because it changes only the dimension of the screen. To have a logarithmic
1709: scale, you must use LOGSCALE intrinsic:
1710: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1711: screen on second scale;
1712: - { X X } autoscale and { Y Y } logscale are now invalid;
1713: - *D is added (depth multiplication, for 3D graphics);
1714: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1715: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1716: - a major bug is fixed in GETI instrinsic when it is used with a name
1717: that contains a matrix or a vector (bad upper bounds conditions in
1718: incrementation);
1719: - DISP intrinsic now uses the 33-th flag. When it is not set
1720: (default), a final carriage return is sent to the terminal;
1721: - AXES intrinsic only takes a list that can contains the keywork
1722: "main" or "auxiliary". Before this modification, this keyword was in
1723: the first stack level;
1724: - vim syntax file is upgraded;
1725: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1726: option;
1727: - LAST is now disabled in the main loop of INT intrinsic;
1728: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1729: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1730: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1731: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1732: in 0);
1733: - LAST is disabled in the main loop of DRAW intrinsic;
1734: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1735: evaluation of an equation, the system stack is returned corrupted to the
1736: sequencer;
1737: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1738: of a loop are not integer or real.
1739: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1740: - the compilation stage aborts with an error message when two definitions
1741: have the same name. To improve the compilation() subroutine, I have to
1742: add some tests in gestion_variables.c;
1743: - recherche_type() subroutine ad some other connex subroutines are improved.
1744: Now, some syntax errors about object are caught and do not perform sequencer
1745: hangup;
1746: - readline is upgraded (minor compilation bug with recent gcc);
1747: - Makefile.am's and configure.in scripts are improved.
1748: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1749: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1750: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1751: the boxwidth, 1 by default);
1752: - recherche_type() is rewritten to be faster;
1753: - gsl is upgraded (release 1.3);
1754: - ncurses is upgraded and patched (release 5.3);
1755: - recherche_instruction_suivante() is fixed (string research with included
1756: '"') and rewritten to be faster;

1768: - vim syntax file is improved;
1769: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1770: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1771: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1772: is a quick and dirty workaround...);
1773: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1774: - rplconvert is improved.

1882: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1883: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1884: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1885: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1886: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1887:
1888: Newton:[~/rpl/rpl] > time make install
1889: ...
1890: real 338m39.623s
1891: user 324m32.290s
1892: sys 10m47.380s
1893: Newton:[~/rpl/rpl] >
1894:
1895: I don't know if you will compile this language on old worstations, but
1896: it is usable ;-) ;
1897: - SYSEVAL is improved. An external program can be called without any shell.
1898: Thus, even if the sticky bit is set, RPL/2 can not give a shell root when
1899: a SYSEVAL command crashes;
