9: Number of scalar operations per second and per core : 2383016
10:
11: - PULPRFL does not abort on BUG() but on execution error;
12: - TRIM, REPL and TOKENIZE are added;
13: - sockets options are now set before bind();
14: - shutdown() is added to all connected sockets;
15: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
16: list argument and inexistant elements).
17: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
18: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
19: signals sent to main process were not caught because DAEMON did not replace
20: old pid by new one;
21: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
22: evaluation when an error is reported from a subroutine in another subroutine.
23: For example, error was not caught in following program when it is executed with
24: -p option :
25: TEST << iferr TEST2 then end >>
26: TEST2 << 0 inv >>
27: - major bug is fixed in variable management. Some local variables were
28: seen as global ones;
29: - major bug is fixed in rplcore. Rplcore entered in dead lock when
30: script file contains a multibyte character;
31: - IN intrinsic is added;
32: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
33: returned false ;
34: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
35: programs;
36: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
37: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
38: strings were never closed;
39: - some bugs have been fixed in file management;
40: - RPL/2 can now be run on EBCDIC systems (OS/390);
41: - major bug is fixed in -A command line option (NULL character is missing);
42: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
43: made by blocks (1024 bytes). When an incomplete multibyte sequence is
44: encountered at end of block, subroutine aborts with an execution error;
45: - major bug is fixed in OPEN (TCP/IPv4 sockets).
46: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
47: - DISP now locks stdout;
48: - rpliconv is added to replace standard iconv provided by operating system.
49: Indeed, conversion between different encodages requires transliteration
50: that is not offered by some iconv utility;
51: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
52: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
53: not be found), SYSEVAL enters in a dead lock;
54: - fprintf is replaced by some functions that allow transliterations between
55: locales;
56: - '"' can now be used in strings ("\"");
57: - iconv is called with -c in preprocessor stage. It is done to write
58: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
59: - double free is fixed in liberation() (type SQL, only occurs when locale is
60: set);
61: - LOCALIZATION, UCASE and LCASE are added;
62: - major bug is fixed in EXIT intrinsic that was able to return a false
63: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
64: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
65: used in onLoading from shared library, USE was pushed on stack as algebraic
66: expression;
67: - libiconv is upgraded to 1.13.1;
68: - gnuplot is upgraded to 4.2.6;
69: - gsl is upgraded to 1.13.
70: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
71: - pipe() is overwritten by a macro to avoid a system error. Communication
72: between process are done with pipes and these pipes are managed by a
73: specific asynchrone thread. If a script try to create more threads than
74: management thread can destroy, you can quickly achieve maximum number of
75: opened files and pipe() shall return a system error. This macro tries to create
76: pipes. If pipe() function returns an error, macro waits and retries. If
77: number of retries is greater than a hardcoded value, macro returns an error;
78: - major bug (deadlock) is fixed in process and thread management. I hope
79: this bug shall be the last one;
80: - major bug is fixed in DET intrinsic (determinant was computed without LU
81: diagonalization);
82: - SWAPCNTXT is added;
83: - minor bug is fixed in Makefile.am (licences rule).
84: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
85: - some bugfixes are added in process management;
86: - all process management is rewritten to avoid usage of defunct process
87: or thread number;
88: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
89: was called before a pending interruption5 (SIGFSTOP), signal handler uses
90: a freed semaphore and corrupts heap;
91: - CLRERR is added to erase previous errors;
92: - ERRN and ERRM return exception message and number;
93: - major bug is fixed in interruptions.c. All signal are now bufferised
94: when semaphore_liste_threads is null to avoid deadlock. This bug only
95: occured when STOP was sent to a dying thread or process (when this thread or
96: process was running retrait_thread());
97: - matrix rank is computed before matrix inversion;
98: - file locks are added to stdin and stdout. stderr is not locked because
99: all messages written by signal handlers are sent to stderr;
100: - configure.in script is modified to test gcc version and avoid a bug in
101: gcc older than 4.4;
102: - some benchmarks have been done :

174: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
175: process is killed;
176: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
177: know typeof() intrinsic function. This function is not standard but exists
178: under Sun Studio, gcc, and maybe some others compilers. If this function does
179: not exist on your compiler, you can change its definition by old one in
180: src/rpl.h;

203: deadlock when a huge amount of threads is launched);
204: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
205: arguments types are unsupported;
206: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
207: data are buffered. PLOT is used to draw these objects.);

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

241: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
242: that all programs that worked with old SQL intrinsic can now work with
243: SQLQUERY. With all new programs, you can open a real connection to databases;
244: - NRPROC is added. This new intrinsic is used to catch error from child
245: process. Without NRPROC, any errors returned by child process cause
246: main process to abort;
247: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
248: starts a new process). There are no mutexes in RPL/2 because all spawned process
249: use specific context. Nevertheless, shared variables and associated mutexes
250: should be added;

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

373: time signals have been removed;
374: - major bugs are fixed in multitasking (mutex trouble _and_ segmentation fault);
375: - minor bug is fixed in STR->. STR-> could return a system error instead an
376: execution one;
377: - first bug due to new garbage collector is fixed in '+' ({ } { } +) and in
378: '-' intrinsics;
379: - PostgreSQL support is written.

382: { "mysql:iso-8859-1" "server" "database" ... };
383: - major bug is fixed un analyse_algebrique(). When DISP printed an algebraic
384: object, 'DISP()' was pushed in stack;

386: - major bug fixed in formateur() (segfault when a symbol is used without "'");
387: - major bug is fixed in DUPN intrinsic;
388: - when software interrupt (SWI) is evaluated, SWI pushs process id on stack
389: before starting interrupt evaluation;
390: - -f parameter is added when iconv is called;
391: - as old file program was bugged, a new option is added to configure script.
392: When configure is called with --disable-encoding-autodetection, make does not
393: try to detect source encoding. Please, do not use if RPL/2 can be built
394: without this option !
395: - new garbage collector (and more efficient) is written;
396: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
397: not support real time signals, RPL/2 cannot use multitasking functions;
398: - error returned by preprocessor are now catched by RPL/2;

545: - external wrapper (rplplot) is written to force usage of gnuplot provided
546: by RPL/2 if it is built during build process. If this build does not exist,
547: it tries to launch regular gnuplot;
548: - gnuplot is added to source tree to avoid some trouble between preinstalled
549: gnuplot and release used by RPL/2. This addition to source tree is

600: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
601: versions of PROTECT and UNPROTECT that only deal with global variables
602: (see RCL/SAVE);
603: - variable management routines have been rewritten. The new ones are
604: uncompatible with the old ones. Before these changes, a local variable

927: on Debian distribution, but since cpp is in the default path, RPL/2 works
928: fine...);
929: - NOT is not correctly formatted in formateur.c:
930: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
931: with a NOTZ function !
932: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

998: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
999: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1000: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1017: - SCLS is added;
1018: - DRWS now uses COLS to draw 2D graphics;
1019: - PPAR and SPAR are written. SPAR returns a list that contains the

1021: statistical variable, or "DISABLED" if its type is not one of the type of
1022: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1023: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1024: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1025: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1026: disabled. Arguments of EXTERNAL are case sensitive because the external
1027: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1028: of known external functions but add the new list to the last. { "all" }
1029: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1030: external names of the known functions;
1031: - mkrplso.in is modified.
1032: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1033: - vim syntax file is upgraded;
1034: - a minor mistake is fixed in recherche_instruction_suivante();

1046: VISIT does not find a name in level 1;
1047: - configure.in script is modified to add a new test (--enable-debug
1048: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1049: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1050: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1051: 'MATRIX' { 2 2 3 } GETR;
1052: - LOGSCALE intrinsic is improved and now, it can be used as
1053: { "main" "auxiliary" X Y } LOGSCALE;
1054: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1055: same than AXES:
1056: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1057: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1058: { { -10 10 } "automatic" } SCALE.
1059: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1060: because it changes only the dimension of the screen. To have a logarithmic
1061: scale, you must use LOGSCALE intrinsic:
1062: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1063: screen on second scale;
1064: - { X X } autoscale and { Y Y } logscale are now invalid;
1065: - *D is added (depth multiplication, for 3D graphics);
1066: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1067: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1068: - a major bug is fixed in GETI instrinsic when it is used with a name
1069: that contains a matrix or a vector (bad upper bounds conditions in
1070: incrementation);
1071: - DISP intrinsic now uses the 33-th flag. When it is not set
1072: (default), a final carriage return is sent to the terminal;
1073: - AXES intrinsic only takes a list that can contains the keywork
1074: "main" or "auxiliary". Before this modification, this keyword was in
1075: the first stack level;
1076: - vim syntax file is upgraded;
1077: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1078: option;
1079: - LAST is now disabled in the main loop of INT intrinsic;
1080: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1081: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1082: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1083: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1084: in 0);
1085: - LAST is disabled in the main loop of DRAW intrinsic;
1086: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1087: evaluation of an equation, the system stack is returned corrupted to the
1088: sequencer;
1089: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1090: of a loop are not integer or real.
1091: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1104: - recherche_type() is rewritten to be faster;
1105: - gsl is upgraded (release 1.3);
1106: - ncurses is upgraded and patched (release 5.3);
1107: - recherche_instruction_suivante() is fixed (string research with included
1108: '"') and rewritten to be faster;

1122: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1123: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1124: is a quick and dirty workaround...);
1125: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1126: - rplconvert is improved.
