464: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
465: "ALL" IMPLICIT when it runs in interactive mode;
466: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
467: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
468: to use SAVE to manipulate global variables;
469: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
470: subroutines;
471: - fix major memory access violation in evaluation subroutine. Only occurs
472: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
473: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
474: when X was a vector or a table.

505: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
506: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
507: corruption. As internal memory management have been improved, a best fit
508: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 509: - gnuplot is upgraded to 4.4.1;
510: - deadlock is fixed in signal handlers: same mutex was used in standard
511: subroutines (without protected sections by sigprocmask() or pthread_sigmask())

559: variable was created and when a local variable existed with the same name,
560: computed address of global variable was wrong;

569: in a compiled program, analyse() caught this error twice and randomly aborted
570: with a segmentation error;
571: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;

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

621: information about shared variable was not copied to new processus structure;
1.19 bertrand 622: - some little memory leaks are fixed in evaluation(), recherche_type() and
623: sequenceur(). They only occured when syntax error were caught;
624: - IMPLICIT causes execution error instead system error;

1.15 bertrand 665: - -a command line option analyzes program (structure and syntax) and
666: sends preprocessor output to standard output. This option is used by
667: rplc (RPL/2 compiler).
1.13 bertrand 668: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
669: - in formatted file, string format returned a variable length string even if
670: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 671: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 672: - keyed access files support is added. Currently, only formatted files are
673: supported;
674: - direct access files support is added. Currenlty, these files can only be used

1.12 bertrand 680: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
681: each execution (md5 and sha1 sums) to enhance security. If one of these tools
682: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
683: on a non recoverable system error;
684: - openssl and sqlite3 libraries are added;
685: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
686: variable indicates RPL/2 root directory. If it is not set, root path
687: is given by configure script (d_exec_path);
1.11 bertrand 688: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

716: - TRIM, REPL and TOKENIZE are added;
717: - sockets options are now set before bind();
718: - shutdown() is added to all connected sockets;
719: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
720: list argument and inexistant elements).
721: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
722: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
723: signals sent to main process were not caught because DAEMON did not replace
724: old pid by new one;
725: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
726: evaluation when an error is reported from a subroutine in another subroutine.
727: For example, error was not caught in following program when it is executed with
728: -p option :
729: TEST << iferr TEST2 then end >>
730: TEST2 << 0 inv >>
731: - major bug is fixed in variable management. Some local variables were
732: seen as global ones;
733: - major bug is fixed in rplcore. Rplcore entered in dead lock when
734: script file contains a multibyte character;
735: - IN intrinsic is added;
736: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
737: returned false ;
738: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
739: programs;
740: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
741: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
742: strings were never closed;
743: - some bugs have been fixed in file management;

745: - major bug is fixed in -A command line option (NULL character is missing);
746: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
747: made by blocks (1024 bytes). When an incomplete multibyte sequence is
748: encountered at end of block, subroutine aborts with an execution error;
749: - major bug is fixed in OPEN (TCP/IPv4 sockets).
750: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
751: - DISP now locks stdout;
752: - rpliconv is added to replace standard iconv provided by operating system.
753: Indeed, conversion between different encodages requires transliteration
754: that is not offered by some iconv utility;
755: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
756: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
757: not be found), SYSEVAL enters in a dead lock;
758: - fprintf is replaced by some functions that allow transliterations between
759: locales;
760: - '"' can now be used in strings ("\"");
761: - iconv is called with -c in preprocessor stage. It is done to write
762: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
763: - double free is fixed in liberation() (type SQL, only occurs when locale is
764: set);
765: - LOCALIZATION, UCASE and LCASE are added;
766: - major bug is fixed in EXIT intrinsic that was able to return a false
767: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
768: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
769: used in onLoading from shared library, USE was pushed on stack as algebraic
770: expression;
771: - libiconv is upgraded to 1.13.1;
772: - gnuplot is upgraded to 4.2.6;
773: - gsl is upgraded to 1.13.
774: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
775: - pipe() is overwritten by a macro to avoid a system error. Communication
776: between process are done with pipes and these pipes are managed by a
777: specific asynchrone thread. If a script try to create more threads than
778: management thread can destroy, you can quickly achieve maximum number of
779: opened files and pipe() shall return a system error. This macro tries to create
780: pipes. If pipe() function returns an error, macro waits and retries. If
781: number of retries is greater than a hardcoded value, macro returns an error;
782: - major bug (deadlock) is fixed in process and thread management. I hope
783: this bug shall be the last one;
784: - major bug is fixed in DET intrinsic (determinant was computed without LU
785: diagonalization);
786: - SWAPCNTXT is added;
787: - minor bug is fixed in Makefile.am (licences rule).

789: - some bugfixes are added in process management;
790: - all process management is rewritten to avoid usage of defunct process
791: or thread number;
792: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
793: was called before a pending interruption5 (SIGFSTOP), signal handler uses
794: a freed semaphore and corrupts heap;
795: - CLRERR is added to erase previous errors;
796: - ERRN and ERRM return exception message and number;
797: - major bug is fixed in interruptions.c. All signal are now bufferised
798: when semaphore_liste_threads is null to avoid deadlock. This bug only
799: occured when STOP was sent to a dying thread or process (when this thread or
800: process was running retrait_thread());
801: - matrix rank is computed before matrix inversion;
802: - file locks are added to stdin and stdout. stderr is not locked because
803: all messages written by signal handlers are sent to stderr;
804: - configure.in script is modified to test gcc version and avoid a bug in
805: gcc older than 4.4;
806: - some benchmarks have been done :

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

947: SQLQUERY. With all new programs, you can open a real connection to databases;
948: - NRPROC is added. This new intrinsic is used to catch error from child
949: process. Without NRPROC, any errors returned by child process cause
950: main process to abort;
951: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
952: starts a new process). There are no mutexes in RPL/2 because all spawned process
953: use specific context. Nevertheless, shared variables and associated mutexes

1098: without this option !
1099: - new garbage collector (and more efficient) is written;
1100: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1101: not support real time signals, RPL/2 cannot use multitasking functions;
1102: - error returned by preprocessor are now catched by RPL/2;
1103: - -p option is added. With this option, all scripts are compiled before
1104: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
1105: 40% faster;
1106: - read and write operations in pipe() are rewritten to be sure that such
1107: operations are atomic;

1303: - PROTECT and UNPROTECT are added to protect variables against write
1304: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1305: versions of PROTECT and UNPROTECT that only deal with global variables
1306: (see RCL/SAVE);
1307: - variable management routines have been rewritten. The new ones are
1308: uncompatible with the old ones. Before these changes, a local variable
1309: was exported to a child subroutine, but cannot be modified into this
1310: child subroutine. Now, a local variable is accessible only in its subroutine;
1311: - SAVE intrinsic is added to manipulate global variables;

1633: - NOT is not correctly formatted in formateur.c:
1634: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1635: with a NOTZ function !
1636: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1702: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1703: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1704: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1723: - PPAR and SPAR are written. SPAR returns a list that contains the
1724: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1725: statistical variable, or "DISABLED" if its type is not one of the type of
1726: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1727: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1728: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1729: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1730: disabled. Arguments of EXTERNAL are case sensitive because the external
1731: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1732: of known external functions but add the new list to the last. { "all" }
1733: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1734: external names of the known functions;
1735: - mkrplso.in is modified.
1736: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1737: - vim syntax file is upgraded;
1738: - a minor mistake is fixed in recherche_instruction_suivante();

1748: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1749: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1750: VISIT does not find a name in level 1;
1751: - configure.in script is modified to add a new test (--enable-debug
1752: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1753: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1754: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1755: 'MATRIX' { 2 2 3 } GETR;
1756: - LOGSCALE intrinsic is improved and now, it can be used as
1757: { "main" "auxiliary" X Y } LOGSCALE;
1758: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1759: same than AXES:
1760: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1761: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1762: { { -10 10 } "automatic" } SCALE.
1763: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1764: because it changes only the dimension of the screen. To have a logarithmic
1765: scale, you must use LOGSCALE intrinsic:
1766: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1767: screen on second scale;
1768: - { X X } autoscale and { Y Y } logscale are now invalid;
1769: - *D is added (depth multiplication, for 3D graphics);
1770: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1771: and Z axes). The result of *S is the same than DUP DUP *H *W *D;

1788: in 0);
1789: - LAST is disabled in the main loop of DRAW intrinsic;
1790: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1791: evaluation of an equation, the system stack is returned corrupted to the
1792: sequencer;
1793: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1794: of a loop are not integer or real.
