189: calling thread;
1.144 bertrand 190: - static variables are now written in a variables tree;
1.136 bertrand 191: - major bug is fixed in STO intrinsic. STO returns an error when it has

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

408: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
409: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
410: corruption. As internal memory management have been improved, a best fit
411: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 412: - gnuplot is upgraded to 4.4.1;
413: - deadlock is fixed in signal handlers: same mutex was used in standard

472: in a compiled program, analyse() caught this error twice and randomly aborted
473: with a segmentation error;
474: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
475: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
476: signals;

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

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

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

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

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

944: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
945: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
946: workaround for this major bug. Nevertheless, all others capabilities seems to
947: work fine;
948: - '->' is modified to return error when program tries to initialiaze two

996: before starting interrupt evaluation;
997: - -f parameter is added when iconv is called;
998: - as old file program was bugged, a new option is added to configure script.
999: When configure is called with --disable-encoding-autodetection, make does not
1000: try to detect source encoding. Please, do not use if RPL/2 can be built
1001: without this option !
1002: - new garbage collector (and more efficient) is written;
1003: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
1004: not support real time signals, RPL/2 cannot use multitasking functions;

1006: - -p option is added. With this option, all scripts are compiled before
1007: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
1008: 40% faster;
1009: - read and write operations in pipe() are rewritten to be sure that such
1010: operations are atomic;

1039: than 1E6;
1040: - numeric and character formats are now tested;
1041: - -A flag is added. -A is used to give command line parameters to main
1042: routine. Example:

1151: - HELP function is rewritten to be more friendly (a la OpenVMS);
1152: - external wrapper (rplplot) is written to force usage of gnuplot provided
1153: by RPL/2 if it is built during build process. If this build does not exist,
1154: it tries to launch regular gnuplot;
1155: - gnuplot is added to source tree to avoid some trouble between preinstalled
1156: gnuplot and release used by RPL/2. This addition to source tree is

1210: - variable management routines have been rewritten. The new ones are
1211: uncompatible with the old ones. Before these changes, a local variable
1212: was exported to a child subroutine, but cannot be modified into this

1535: fine...);
1536: - NOT is not correctly formatted in formateur.c:
1537: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1538: with a NOTZ function !
1539: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1540: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1542: - RPL/2 is tested with efence and valgrind;
1543: - configure.in script is modified;
1544: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1605: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1606: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1607: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1624: - SCLS is added;
1625: - DRWS now uses COLS to draw 2D graphics;
1626: - PPAR and SPAR are written. SPAR returns a list that contains the
1627: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1628: statistical variable, or "DISABLED" if its type is not one of the type of
1629: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1630: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1631: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1632: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1633: disabled. Arguments of EXTERNAL are case sensitive because the external
1634: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1635: of known external functions but add the new list to the last. { "all" }
1636: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1637: external names of the known functions;
1638: - mkrplso.in is modified.
1639: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1640: - vim syntax file is upgraded;
1641: - a minor mistake is fixed in recherche_instruction_suivante();
1642: - some minor memory leaks are fixed in recherche_type() function. They only

1651: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1652: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1653: VISIT does not find a name in level 1;
1654: - configure.in script is modified to add a new test (--enable-debug
1655: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1656: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1657: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1658: 'MATRIX' { 2 2 3 } GETR;
1659: - LOGSCALE intrinsic is improved and now, it can be used as
1660: { "main" "auxiliary" X Y } LOGSCALE;
1661: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1662: same than AXES:
1663: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1664: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1665: { { -10 10 } "automatic" } SCALE.
1666: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1667: because it changes only the dimension of the screen. To have a logarithmic
1668: scale, you must use LOGSCALE intrinsic:
1669: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1670: screen on second scale;
1671: - { X X } autoscale and { Y Y } logscale are now invalid;
1672: - *D is added (depth multiplication, for 3D graphics);
1673: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1674: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1675: - a major bug is fixed in GETI instrinsic when it is used with a name
1676: that contains a matrix or a vector (bad upper bounds conditions in
1677: incrementation);
1678: - DISP intrinsic now uses the 33-th flag. When it is not set
1679: (default), a final carriage return is sent to the terminal;
1680: - AXES intrinsic only takes a list that can contains the keywork
1681: "main" or "auxiliary". Before this modification, this keyword was in
1682: the first stack level;
1683: - vim syntax file is upgraded;
1684: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1685: option;
1686: - LAST is now disabled in the main loop of INT intrinsic;
1687: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1688: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1689: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1690: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1691: in 0);
1692: - LAST is disabled in the main loop of DRAW intrinsic;
1693: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1694: evaluation of an equation, the system stack is returned corrupted to the
1695: sequencer;
1696: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1697: of a loop are not integer or real.
1698: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1699: - the compilation stage aborts with an error message when two definitions
1700: have the same name. To improve the compilation() subroutine, I have to
1701: add some tests in gestion_variables.c;
1702: - recherche_type() subroutine ad some other connex subroutines are improved.
1703: Now, some syntax errors about object are caught and do not perform sequencer
1704: hangup;
1705: - readline is upgraded (minor compilation bug with recent gcc);
1706: - Makefile.am's and configure.in scripts are improved.
1707: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1708: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1709: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1710: the boxwidth, 1 by default);
1711: - recherche_type() is rewritten to be faster;
1712: - gsl is upgraded (release 1.3);
1713: - ncurses is upgraded and patched (release 5.3);
1714: - recherche_instruction_suivante() is fixed (string research with included
1715: '"') and rewritten to be faster;

1726: - a minor bug is fixed in evaluation subroutine;
1727: - vim syntax file is improved;
1728: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1729: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1730: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1731: is a quick and dirty workaround...);
1732: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1733: - rplconvert is improved.

1815: deleted too!;
1816: - configure script is improved (and it seems to be good ;-) );
1817: - An --disable-experimental flag is added to the configure script. Thus, even
1818: if you compile a beta release, you can compile a stable RPL/2;
1819: - new syntax and ftplugin written for vim 6.0.

1832: that the RPL/2 seqencer must stop and must give a prompt. This
1833: signal is an asynchonous "HALT" command;
1834: - SIGINT (CTRL+C) variables stack corruption is fixed;
1835: - IFERR seems to be fixed (in equation evaluation routine);
1836: - Memory leak is fixed (ADR object type);

1843: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1844: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1845: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1846:
1847: Newton:[~/rpl/rpl] > time make install
1848: ...
1849: real 338m39.623s
1850: user 324m32.290s
1851: sys 10m47.380s
1852: Newton:[~/rpl/rpl] >
1853:
1854: I don't know if you will compile this language on old worstations, but
1855: it is usable ;-) ;
1856: - SYSEVAL is improved. An external program can be called without any shell.
