185: calling thread;
1.144 bertrand 186: - static variables are now written in a variables tree;
1.136 bertrand 187: - major bug is fixed in STO intrinsic. STO returns an error when it has

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

404: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
405: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
406: corruption. As internal memory management have been improved, a best fit
407: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 408: - gnuplot is upgraded to 4.4.1;
409: - deadlock is fixed in signal handlers: same mutex was used in standard

465: when this structure is included in IFERR/THEN/END structure and when an error is
466: caught;
467: - major bug is fixed in analyse() subroutine. When evaluation() returned error
468: in a compiled program, analyse() caught this error twice and randomly aborted
469: with a segmentation error;
470: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
471: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
472: signals;

679: pipes. If pipe() function returns an error, macro waits and retries. If
680: number of retries is greater than a hardcoded value, macro returns an error;
681: - major bug (deadlock) is fixed in process and thread management. I hope
682: this bug shall be the last one;
683: - major bug is fixed in DET intrinsic (determinant was computed without LU
684: diagonalization);
685: - SWAPCNTXT is added;
686: - minor bug is fixed in Makefile.am (licences rule).
687: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
688: - some bugfixes are added in process management;
689: - all process management is rewritten to avoid usage of defunct process
690: or thread number;
691: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
692: was called before a pending interruption5 (SIGFSTOP), signal handler uses
693: a freed semaphore and corrupts heap;
694: - CLRERR is added to erase previous errors;
695: - ERRN and ERRM return exception message and number;
696: - major bug is fixed in interruptions.c. All signal are now bufferised
697: when semaphore_liste_threads is null to avoid deadlock. This bug only
698: occured when STOP was sent to a dying thread or process (when this thread or
699: process was running retrait_thread());
700: - matrix rank is computed before matrix inversion;
701: - file locks are added to stdin and stdout. stderr is not locked because
702: all messages written by signal handlers are sent to stderr;
703: - configure.in script is modified to test gcc version and avoid a bug in
704: gcc older than 4.4;
705: - some benchmarks have been done :

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

806: deadlock when a huge amount of threads is launched);
807: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
808: arguments types are unsupported;
809: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

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

845: that all programs that worked with old SQL intrinsic can now work with
846: SQLQUERY. With all new programs, you can open a real connection to databases;
847: - NRPROC is added. This new intrinsic is used to catch error from child
848: process. Without NRPROC, any errors returned by child process cause
849: main process to abort;
850: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
851: starts a new process). There are no mutexes in RPL/2 because all spawned process
852: use specific context. Nevertheless, shared variables and associated mutexes
853: should be added;

993: - -f parameter is added when iconv is called;
994: - as old file program was bugged, a new option is added to configure script.
995: When configure is called with --disable-encoding-autodetection, make does not
996: try to detect source encoding. Please, do not use if RPL/2 can be built
997: without this option !
998: - new garbage collector (and more efficient) is written;

1035: than 1E6;
1036: - numeric and character formats are now tested;
1037: - -A flag is added. -A is used to give command line parameters to main
1038: routine. Example:

1147: - HELP function is rewritten to be more friendly (a la OpenVMS);
1148: - external wrapper (rplplot) is written to force usage of gnuplot provided
1149: by RPL/2 if it is built during build process. If this build does not exist,
1150: it tries to launch regular gnuplot;
1151: - gnuplot is added to source tree to avoid some trouble between preinstalled
1152: gnuplot and release used by RPL/2. This addition to source tree is

1206: - variable management routines have been rewritten. The new ones are
1207: uncompatible with the old ones. Before these changes, a local variable
1208: was exported to a child subroutine, but cannot be modified into this
1209: child subroutine. Now, a local variable is accessible only in its subroutine;

1531: fine...);
1532: - NOT is not correctly formatted in formateur.c:
1533: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1534: with a NOTZ function !
1535: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1538: - RPL/2 is tested with efence and valgrind;
1539: - configure.in script is modified;
1540: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1620: - SCLS is added;
1621: - DRWS now uses COLS to draw 2D graphics;
1622: - PPAR and SPAR are written. SPAR returns a list that contains the
1623: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1624: statistical variable, or "DISABLED" if its type is not one of the type of
1625: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1626: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1627: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1628: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1629: disabled. Arguments of EXTERNAL are case sensitive because the external
1630: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1631: of known external functions but add the new list to the last. { "all" }
1632: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1633: external names of the known functions;
1634: - mkrplso.in is modified.
1635: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1649: VISIT does not find a name in level 1;
1650: - configure.in script is modified to add a new test (--enable-debug
1651: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1652: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1653: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1654: 'MATRIX' { 2 2 3 } GETR;
1655: - LOGSCALE intrinsic is improved and now, it can be used as
1656: { "main" "auxiliary" X Y } LOGSCALE;
1657: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1658: same than AXES:
1659: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1660: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1661: { { -10 10 } "automatic" } SCALE.
1662: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1663: because it changes only the dimension of the screen. To have a logarithmic
1664: scale, you must use LOGSCALE intrinsic:
1665: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1666: screen on second scale;
1667: - { X X } autoscale and { Y Y } logscale are now invalid;
1668: - *D is added (depth multiplication, for 3D graphics);
1669: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1670: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1671: - a major bug is fixed in GETI instrinsic when it is used with a name
1672: that contains a matrix or a vector (bad upper bounds conditions in
1673: incrementation);
1674: - DISP intrinsic now uses the 33-th flag. When it is not set
1675: (default), a final carriage return is sent to the terminal;
1676: - AXES intrinsic only takes a list that can contains the keywork
1677: "main" or "auxiliary". Before this modification, this keyword was in
1678: the first stack level;
1679: - vim syntax file is upgraded;
1680: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1681: option;
1682: - LAST is now disabled in the main loop of INT intrinsic;
1683: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1684: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1685: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1686: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1687: in 0);
1688: - LAST is disabled in the main loop of DRAW intrinsic;
1689: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1690: evaluation of an equation, the system stack is returned corrupted to the
1691: sequencer;
1692: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1693: of a loop are not integer or real.
1694: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1696: have the same name. To improve the compilation() subroutine, I have to
1697: add some tests in gestion_variables.c;
1698: - recherche_type() subroutine ad some other connex subroutines are improved.
1699: Now, some syntax errors about object are caught and do not perform sequencer
1700: hangup;
1701: - readline is upgraded (minor compilation bug with recent gcc);
1702: - Makefile.am's and configure.in scripts are improved.
1703: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1704: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1705: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1707: - recherche_type() is rewritten to be faster;
1708: - gsl is upgraded (release 1.3);
1709: - ncurses is upgraded and patched (release 5.3);
1710: - recherche_instruction_suivante() is fixed (string research with included
1711: '"') and rewritten to be faster;

1725: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1726: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1727: is a quick and dirty workaround...);
1728: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1729: - rplconvert is improved.

1787: 'X' 0 + and 0 'X' + return 'X';
1788: 'X' 0 - returns 'X';
1789: 'X' 1 * and 1 'X' * return 'X';

1795: found by configure are used in rpltypes.h (rplconfig.h is written by configure);
1796: - rdynamic flag is added in src/Makefile.am. This flag is used in the first
1797: makefile, but forgotten in the new process;
1798: - Flag 31 is tested before saving any arguments in bibliotheques_externes.c;
1799: - POS can now be used on lists;

1811: deleted too!;
1812: - configure script is improved (and it seems to be good ;-) );
1813: - An --disable-experimental flag is added to the configure script. Thus, even
1814: if you compile a beta release, you can compile a stable RPL/2;
1815: - new syntax and ftplugin written for vim 6.0.

1828: that the RPL/2 seqencer must stop and must give a prompt. This
1829: signal is an asynchonous "HALT" command;
1830: - SIGINT (CTRL+C) variables stack corruption is fixed;
1831: - IFERR seems to be fixed (in equation evaluation routine);
1832: - Memory leak is fixed (ADR object type);

1839: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1840: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1841: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1842:
1843: Newton:[~/rpl/rpl] > time make install
1844: ...
1845: real 338m39.623s
1846: user 324m32.290s
1847: sys 10m47.380s
1848: Newton:[~/rpl/rpl] >
1849:
1850: I don't know if you will compile this language on old worstations, but
1851: it is usable ;-) ;
1852: - SYSEVAL is improved. An external program can be called without any shell.
