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

419: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
420: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
421: corruption. As internal memory management have been improved, a best fit
422: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 423: - gnuplot is upgraded to 4.4.1;
424: - deadlock is fixed in signal handlers: same mutex was used in standard

446: systems that does not provide correct POSIX or SysV semaphores subsystem;
447: - a dirty but not quick patch is written to workaround broken siginfo
448: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 449: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process

471: a name of RPL/2 routine;
1.35 bertrand 472: - major bug is fixed in global variable creation subroutine. When a global
473: variable was created and when a local variable existed with the same name,
474: computed address of global variable was wrong;
475: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
476: is forced in front of all libraries.

480: when this structure is included in IFERR/THEN/END structure and when an error is
481: caught;
482: - major bug is fixed in analyse() subroutine. When evaluation() returned error
483: in a compiled program, analyse() caught this error twice and randomly aborted
484: with a segmentation error;
485: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
486: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
487: signals;

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

677: - double free is fixed in liberation() (type SQL, only occurs when locale is
678: set);
679: - LOCALIZATION, UCASE and LCASE are added;
680: - major bug is fixed in EXIT intrinsic that was able to return a false
681: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
682: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
683: used in onLoading from shared library, USE was pushed on stack as algebraic
684: expression;
685: - libiconv is upgraded to 1.13.1;
686: - gnuplot is upgraded to 4.2.6;
687: - gsl is upgraded to 1.13.
688: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
689: - pipe() is overwritten by a macro to avoid a system error. Communication
690: between process are done with pipes and these pipes are managed by a
691: specific asynchrone thread. If a script try to create more threads than
692: management thread can destroy, you can quickly achieve maximum number of
693: opened files and pipe() shall return a system error. This macro tries to create
694: pipes. If pipe() function returns an error, macro waits and retries. If
695: number of retries is greater than a hardcoded value, macro returns an error;
696: - major bug (deadlock) is fixed in process and thread management. I hope
697: this bug shall be the last one;
698: - major bug is fixed in DET intrinsic (determinant was computed without LU
699: diagonalization);
700: - SWAPCNTXT is added;
701: - minor bug is fixed in Makefile.am (licences rule).
702: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
703: - some bugfixes are added in process management;
704: - all process management is rewritten to avoid usage of defunct process
705: or thread number;
706: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
707: was called before a pending interruption5 (SIGFSTOP), signal handler uses
708: a freed semaphore and corrupts heap;
709: - CLRERR is added to erase previous errors;
710: - ERRN and ERRM return exception message and number;
711: - major bug is fixed in interruptions.c. All signal are now bufferised
712: when semaphore_liste_threads is null to avoid deadlock. This bug only
713: occured when STOP was sent to a dying thread or process (when this thread or
714: process was running retrait_thread());
715: - matrix rank is computed before matrix inversion;
716: - file locks are added to stdin and stdout. stderr is not locked because
717: all messages written by signal handlers are sent to stderr;
718: - configure.in script is modified to test gcc version and avoid a bug in
719: gcc older than 4.4;
720: - some benchmarks have been done :

792: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
793: process is killed;
794: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
795: know typeof() intrinsic function. This function is not standard but exists
796: under Sun Studio, gcc, and maybe some others compilers. If this function does
797: not exist on your compiler, you can change its definition by old one in
798: src/rpl.h;
799: - fflush() can now be interrupted by signal (SunOS);
800: - fflush(NULL) is called before all fork() occurrences;

821: deadlock when a huge amount of threads is launched);
822: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
823: arguments types are unsupported;
824: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
825: data are buffered. PLOT is used to draw these objects.);
826: - MARK instrinsic is added;
827: - new allocator mechanism is written;
828: - some regression bugs have been fixed, some memory leaks too.
829: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)

839: static variable that is shared by multiple threads;
840: - '->' intrinsic is improved. All object copies have been avoided;
841: - -n flag is added to catch HUP signal. stderr and stdout are redirected
842: to a file, stdin is redirected to /dev/null when control process is killed;
843: - a mutex is added to each object (before this modification,
844: RPL/2 used a global mutex and performances in multithreaded programs were very
845: poor.);

859: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
860: that all programs that worked with old SQL intrinsic can now work with
861: SQLQUERY. With all new programs, you can open a real connection to databases;
862: - NRPROC is added. This new intrinsic is used to catch error from child
863: process. Without NRPROC, any errors returned by child process cause
864: main process to abort;
865: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
866: starts a new process). There are no mutexes in RPL/2 because all spawned process
867: use specific context. Nevertheless, shared variables and associated mutexes
868: should be added;
869: - -D flag and DAEMONIZE intrinsic have been added;

919: - ->TABLE and TABLE-> intrinsics are added;
920: - major bug is fixed in recherche_type(). Only occurs when rpl executes
921: precompiled scripts;

939: nullified lists;
940: - rplexternals.h is modified and improved;
941: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and

954: - FUSE, RFUSE and CLRFUSE have been added;
955: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
956: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
957: workaround for this major bug. Nevertheless, all others capabilities seems to
958: work fine;
959: - '->' is modified to return error when program tries to initialiaze two

1007: before starting interrupt evaluation;
1008: - -f parameter is added when iconv is called;
1009: - as old file program was bugged, a new option is added to configure script.
1010: When configure is called with --disable-encoding-autodetection, make does not
1011: try to detect source encoding. Please, do not use if RPL/2 can be built
1012: without this option !
1013: - new garbage collector (and more efficient) is written;
1014: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1015: not support real time signals, RPL/2 cannot use multitasking functions;
1016: - error returned by preprocessor are now catched by RPL/2;
1017: - -p option is added. With this option, all scripts are compiled before
1018: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run

1050: than 1E6;
1051: - numeric and character formats are now tested;
1052: - -A flag is added. -A is used to give command line parameters to main
1053: routine. Example:

1162: - HELP function is rewritten to be more friendly (a la OpenVMS);
1163: - external wrapper (rplplot) is written to force usage of gnuplot provided
1164: by RPL/2 if it is built during build process. If this build does not exist,
1165: it tries to launch regular gnuplot;
1166: - gnuplot is added to source tree to avoid some trouble between preinstalled
1167: gnuplot and release used by RPL/2. This addition to source tree is

1546: fine...);
1547: - NOT is not correctly formatted in formateur.c:
1548: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1549: with a NOTZ function !
1550: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1553: - RPL/2 is tested with efence and valgrind;
1554: - configure.in script is modified;
1555: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1616: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1617: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1618: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1635: - SCLS is added;
1636: - DRWS now uses COLS to draw 2D graphics;
1637: - PPAR and SPAR are written. SPAR returns a list that contains the
1638: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1639: statistical variable, or "DISABLED" if its type is not one of the type of
1640: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1641: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1642: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1643: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1644: disabled. Arguments of EXTERNAL are case sensitive because the external
1645: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1646: of known external functions but add the new list to the last. { "all" }
1647: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1648: external names of the known functions;
1649: - mkrplso.in is modified.
1650: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1664: VISIT does not find a name in level 1;
1665: - configure.in script is modified to add a new test (--enable-debug
1666: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1667: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1668: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1669: 'MATRIX' { 2 2 3 } GETR;
1670: - LOGSCALE intrinsic is improved and now, it can be used as
1671: { "main" "auxiliary" X Y } LOGSCALE;
1672: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1673: same than AXES:
1674: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1675: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1676: { { -10 10 } "automatic" } SCALE.
1677: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1678: because it changes only the dimension of the screen. To have a logarithmic
1679: scale, you must use LOGSCALE intrinsic:
1680: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1681: screen on second scale;
1682: - { X X } autoscale and { Y Y } logscale are now invalid;
1683: - *D is added (depth multiplication, for 3D graphics);
1684: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1685: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1686: - a major bug is fixed in GETI instrinsic when it is used with a name
1687: that contains a matrix or a vector (bad upper bounds conditions in
1688: incrementation);
1689: - DISP intrinsic now uses the 33-th flag. When it is not set
1690: (default), a final carriage return is sent to the terminal;
1691: - AXES intrinsic only takes a list that can contains the keywork
1692: "main" or "auxiliary". Before this modification, this keyword was in
1693: the first stack level;
1694: - vim syntax file is upgraded;
1695: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1696: option;
1697: - LAST is now disabled in the main loop of INT intrinsic;
1698: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1699: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1700: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1701: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1702: in 0);
1703: - LAST is disabled in the main loop of DRAW intrinsic;
1704: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1705: evaluation of an equation, the system stack is returned corrupted to the
1706: sequencer;
1707: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1708: of a loop are not integer or real.
1709: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1712: add some tests in gestion_variables.c;
1713: - recherche_type() subroutine ad some other connex subroutines are improved.
1714: Now, some syntax errors about object are caught and do not perform sequencer
1715: hangup;
1716: - readline is upgraded (minor compilation bug with recent gcc);
1717: - Makefile.am's and configure.in scripts are improved.
1718: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1719: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1720: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1722: - recherche_type() is rewritten to be faster;
1723: - gsl is upgraded (release 1.3);
1724: - ncurses is upgraded and patched (release 5.3);
1725: - recherche_instruction_suivante() is fixed (string research with included
1726: '"') and rewritten to be faster;

1737: - a minor bug is fixed in evaluation subroutine;
1738: - vim syntax file is improved;
1739: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1740: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1741: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1742: is a quick and dirty workaround...);
1743: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1744: - rplconvert is improved.

1826: deleted too!;
1827: - configure script is improved (and it seems to be good ;-) );

1844: signal is an asynchonous "HALT" command;
1845: - SIGINT (CTRL+C) variables stack corruption is fixed;
1846: - IFERR seems to be fixed (in equation evaluation routine);

1855: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1856: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1857:
1858: Newton:[~/rpl/rpl] > time make install
1859: ...
1860: real 338m39.623s
1861: user 324m32.290s
