488: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
489: "ALL" IMPLICIT when it runs in interactive mode;
490: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
491: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
492: to use SAVE to manipulate global variables;
493: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
494: subroutines;
495: - fix major memory access violation in evaluation subroutine. Only occurs
496: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
497: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
498: when X was a vector or a table.

529: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
530: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
531: corruption. As internal memory management have been improved, a best fit
532: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 533: - gnuplot is upgraded to 4.4.1;
534: - deadlock is fixed in signal handlers: same mutex was used in standard

1.13 bertrand 692: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
693: - in formatted file, string format returned a variable length string even if
694: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 695: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 696: - keyed access files support is added. Currently, only formatted files are
697: supported;

707: on a non recoverable system error;
708: - openssl and sqlite3 libraries are added;
709: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
710: variable indicates RPL/2 root directory. If it is not set, root path
711: is given by configure script (d_exec_path);
1.11 bertrand 712: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

745: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
746: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
747: signals sent to main process were not caught because DAEMON did not replace
748: old pid by new one;
749: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
750: evaluation when an error is reported from a subroutine in another subroutine.
751: For example, error was not caught in following program when it is executed with
752: -p option :
753: TEST << iferr TEST2 then end >>
754: TEST2 << 0 inv >>
755: - major bug is fixed in variable management. Some local variables were
756: seen as global ones;

758: script file contains a multibyte character;
759: - IN intrinsic is added;
760: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
761: returned false ;
762: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
763: programs;
764: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
765: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
766: strings were never closed;

773: - major bug is fixed in OPEN (TCP/IPv4 sockets).
774: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
775: - DISP now locks stdout;
776: - rpliconv is added to replace standard iconv provided by operating system.
777: Indeed, conversion between different encodages requires transliteration
778: that is not offered by some iconv utility;
779: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
780: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
781: not be found), SYSEVAL enters in a dead lock;
782: - fprintf is replaced by some functions that allow transliterations between
783: locales;
784: - '"' can now be used in strings ("\"");
785: - iconv is called with -c in preprocessor stage. It is done to write
786: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
787: - double free is fixed in liberation() (type SQL, only occurs when locale is
788: set);
789: - LOCALIZATION, UCASE and LCASE are added;
790: - major bug is fixed in EXIT intrinsic that was able to return a false
791: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
792: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
793: used in onLoading from shared library, USE was pushed on stack as algebraic

799: - pipe() is overwritten by a macro to avoid a system error. Communication
800: between process are done with pipes and these pipes are managed by a
801: specific asynchrone thread. If a script try to create more threads than
802: management thread can destroy, you can quickly achieve maximum number of
803: opened files and pipe() shall return a system error. This macro tries to create
804: pipes. If pipe() function returns an error, macro waits and retries. If
805: number of retries is greater than a hardcoded value, macro returns an error;
806: - major bug (deadlock) is fixed in process and thread management. I hope
807: this bug shall be the last one;
808: - major bug is fixed in DET intrinsic (determinant was computed without LU
809: diagonalization);

813: - some bugfixes are added in process management;
814: - all process management is rewritten to avoid usage of defunct process
815: or thread number;
816: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
817: was called before a pending interruption5 (SIGFSTOP), signal handler uses
818: a freed semaphore and corrupts heap;
819: - CLRERR is added to erase previous errors;
820: - ERRN and ERRM return exception message and number;
821: - major bug is fixed in interruptions.c. All signal are now bufferised
822: when semaphore_liste_threads is null to avoid deadlock. This bug only
823: occured when STOP was sent to a dying thread or process (when this thread or
824: process was running retrait_thread());
825: - matrix rank is computed before matrix inversion;
826: - file locks are added to stdin and stdout. stderr is not locked because
827: all messages written by signal handlers are sent to stderr;
828: - configure.in script is modified to test gcc version and avoid a bug in
829: gcc older than 4.4;

902: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
903: process is killed;
904: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
905: know typeof() intrinsic function. This function is not standard but exists
906: under Sun Studio, gcc, and maybe some others compilers. If this function does

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

970: that all programs that worked with old SQL intrinsic can now work with
971: SQLQUERY. With all new programs, you can open a real connection to databases;
972: - NRPROC is added. This new intrinsic is used to catch error from child
973: process. Without NRPROC, any errors returned by child process cause
974: main process to abort;
975: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
976: starts a new process). There are no mutexes in RPL/2 because all spawned process
977: use specific context. Nevertheless, shared variables and associated mutexes
978: should be added;

1064: - FUSE, RFUSE and CLRFUSE have been added;
1065: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
1066: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
1067: workaround for this major bug. Nevertheless, all others capabilities seems to
1068: work fine;

1122: without this option !
1123: - new garbage collector (and more efficient) is written;
1124: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1125: not support real time signals, RPL/2 cannot use multitasking functions;
1126: - error returned by preprocessor are now catched by RPL/2;
1127: - -p option is added. With this option, all scripts are compiled before
1128: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
1129: 40% faster;
1130: - read and write operations in pipe() are rewritten to be sure that such
1131: operations are atomic;
1132: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

1326: With STATIC, next variables created by '->' are static;
1327: - PROTECT and UNPROTECT are added to protect variables against write
1328: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1329: versions of PROTECT and UNPROTECT that only deal with global variables
1330: (see RCL/SAVE);
1331: - variable management routines have been rewritten. The new ones are
1332: uncompatible with the old ones. Before these changes, a local variable
1333: was exported to a child subroutine, but cannot be modified into this

1768: - a minor bug is fixed in analyse.c;
1769: - DEBIAN/control is added to build debian package;
1770: - SCALE is fixed and improved ("automatic" keyword);
1771: - PUTC and PUTR new intrinsics are added.
1772: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1773: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1774: VISIT does not find a name in level 1;
1775: - configure.in script is modified to add a new test (--enable-debug
1776: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1777: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1778: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1779: 'MATRIX' { 2 2 3 } GETR;
1780: - LOGSCALE intrinsic is improved and now, it can be used as
1781: { "main" "auxiliary" X Y } LOGSCALE;
1782: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1783: same than AXES:
1784: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1785: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1786: { { -10 10 } "automatic" } SCALE.
1787: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1788: because it changes only the dimension of the screen. To have a logarithmic
1789: scale, you must use LOGSCALE intrinsic:
1790: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1791: screen on second scale;
1792: - { X X } autoscale and { Y Y } logscale are now invalid;
1793: - *D is added (depth multiplication, for 3D graphics);
1794: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1795: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1796: - a major bug is fixed in GETI instrinsic when it is used with a name
1797: that contains a matrix or a vector (bad upper bounds conditions in
1798: incrementation);
1799: - DISP intrinsic now uses the 33-th flag. When it is not set
1800: (default), a final carriage return is sent to the terminal;
1801: - AXES intrinsic only takes a list that can contains the keywork
1802: "main" or "auxiliary". Before this modification, this keyword was in
1803: the first stack level;
1804: - vim syntax file is upgraded;
1805: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1806: option;
1807: - LAST is now disabled in the main loop of INT intrinsic;
1808: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1809: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1810: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1811: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1812: in 0);
1813: - LAST is disabled in the main loop of DRAW intrinsic;
1814: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1815: evaluation of an equation, the system stack is returned corrupted to the
1816: sequencer;
1817: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1818: of a loop are not integer or real.
1819: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1820: - the compilation stage aborts with an error message when two definitions
1821: have the same name. To improve the compilation() subroutine, I have to
1822: add some tests in gestion_variables.c;
1823: - recherche_type() subroutine ad some other connex subroutines are improved.
1824: Now, some syntax errors about object are caught and do not perform sequencer
1825: hangup;

1827: - Makefile.am's and configure.in scripts are improved.
1828: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1829: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1830: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1831: the boxwidth, 1 by default);
1832: - recherche_type() is rewritten to be faster;
1833: - gsl is upgraded (release 1.3);
1834: - ncurses is upgraded and patched (release 5.3);
1835: - recherche_instruction_suivante() is fixed (string research with included
1836: '"') and rewritten to be faster;

1847: - a minor bug is fixed in evaluation subroutine;
1848: - vim syntax file is improved;
1849: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1850: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1851: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1852: is a quick and dirty workaround...);
1853: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1854: - rplconvert is improved.
1855: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
