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

521: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
522: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
523: corruption. As internal memory management have been improved, a best fit
524: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 525: - gnuplot is upgraded to 4.4.1;
526: - deadlock is fixed in signal handlers: same mutex was used in standard
527: subroutines (without protected sections by sigprocmask() or pthread_sigmask())

530: that has to be evaluated by ->NUM;
1.49 bertrand 531: - rplfile build process is modify to be sure that rplfile is not modified
532: after rpl build stage (to be sure that rplfile checksum is not modified after

573: a name of RPL/2 routine;
1.35 bertrand 574: - major bug is fixed in global variable creation subroutine. When a global
575: variable was created and when a local variable existed with the same name,
576: computed address of global variable was wrong;

583: caught;
584: - major bug is fixed in analyse() subroutine. When evaluation() returned error
585: in a compiled program, analyse() caught this error twice and randomly aborted
586: with a segmentation error;
587: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;

614: and to not use swap;
1.26 bertrand 615: - major bug is fixed in sql support. SQL connections were closed in all chield
616: process;
617: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
618: discovered in Solaris thread safe allocators (libmalloc and libumem) that

637: information about shared variable was not copied to new processus structure;
1.19 bertrand 638: - some little memory leaks are fixed in evaluation(), recherche_type() and
639: sequenceur(). They only occured when syntax error were caught;
640: - IMPLICIT causes execution error instead system error;

1.13 bertrand 684: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
685: - in formatted file, string format returned a variable length string even if
686: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 687: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 688: - keyed access files support is added. Currently, only formatted files are
689: supported;

699: on a non recoverable system error;
700: - openssl and sqlite3 libraries are added;
701: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
702: variable indicates RPL/2 root directory. If it is not set, root path
703: is given by configure script (d_exec_path);
1.11 bertrand 704: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

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

750: script file contains a multibyte character;
751: - IN intrinsic is added;
752: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
753: returned false ;
754: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
755: programs;
756: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
757: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
758: strings were never closed;

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

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

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

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

962: that all programs that worked with old SQL intrinsic can now work with
963: SQLQUERY. With all new programs, you can open a real connection to databases;
964: - NRPROC is added. This new intrinsic is used to catch error from child
965: process. Without NRPROC, any errors returned by child process cause
966: main process to abort;
967: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
968: starts a new process). There are no mutexes in RPL/2 because all spawned process
969: use specific context. Nevertheless, shared variables and associated mutexes

1117: not support real time signals, RPL/2 cannot use multitasking functions;
1118: - error returned by preprocessor are now catched by RPL/2;
1119: - -p option is added. With this option, all scripts are compiled before
1120: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
1121: 40% faster;
1122: - read and write operations in pipe() are rewritten to be sure that such
1123: operations are atomic;

1320: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
1321: versions of PROTECT and UNPROTECT that only deal with global variables
1322: (see RCL/SAVE);
1323: - variable management routines have been rewritten. The new ones are
1324: uncompatible with the old ones. Before these changes, a local variable
1325: was exported to a child subroutine, but cannot be modified into this

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

1821: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1822: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1839: - a minor bug is fixed in evaluation subroutine;
1840: - vim syntax file is improved;
1841: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1842: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1843: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1844: is a quick and dirty workaround...);
1845: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1846: - rplconvert is improved.
1847: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1957: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1958: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1959:
1960: Newton:[~/rpl/rpl] > time make install
