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

183: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
184: process is killed;
185: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
186: know typeof() intrinsic function. This function is not standard but exists
187: under Sun Studio, gcc, and maybe some others compilers. If this function does
188: not exist on your compiler, you can change its definition by old one in

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

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

252: SQLQUERY. With all new programs, you can open a real connection to databases;
253: - NRPROC is added. This new intrinsic is used to catch error from child
254: process. Without NRPROC, any errors returned by child process cause
255: main process to abort;
256: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
257: starts a new process). There are no mutexes in RPL/2 because all spawned process
258: use specific context. Nevertheless, shared variables and associated mutexes
259: should be added;

403: without this option !
404: - new garbage collector (and more efficient) is written;
405: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
406: not support real time signals, RPL/2 cannot use multitasking functions;

410: 40% faster;
411: - read and write operations in pipe() are rewritten to be sure that such
412: operations are atomic;
413: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

609: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
610: versions of PROTECT and UNPROTECT that only deal with global variables
611: (see RCL/SAVE);
612: - variable management routines have been rewritten. The new ones are
613: uncompatible with the old ones. Before these changes, a local variable
614: was exported to a child subroutine, but cannot be modified into this
615: child subroutine. Now, a local variable is accessible only in its subroutine;
616: - SAVE intrinsic is added to manipulate global variables;

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

1007: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1008: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1009: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1026: - SCLS is added;
1027: - DRWS now uses COLS to draw 2D graphics;
1028: - PPAR and SPAR are written. SPAR returns a list that contains the

1030: statistical variable, or "DISABLED" if its type is not one of the type of
1031: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1032: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1033: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1034: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1035: disabled. Arguments of EXTERNAL are case sensitive because the external
1036: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1037: of known external functions but add the new list to the last. { "all" }
1038: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1039: external names of the known functions;
1040: - mkrplso.in is modified.

1054: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1055: VISIT does not find a name in level 1;
1056: - configure.in script is modified to add a new test (--enable-debug
1057: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1058: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1059: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1060: 'MATRIX' { 2 2 3 } GETR;
1061: - LOGSCALE intrinsic is improved and now, it can be used as
1062: { "main" "auxiliary" X Y } LOGSCALE;
1063: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1064: same than AXES:
1065: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1066: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1067: { { -10 10 } "automatic" } SCALE.
1068: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1069: because it changes only the dimension of the screen. To have a logarithmic
1070: scale, you must use LOGSCALE intrinsic:
1071: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1072: screen on second scale;
1073: - { X X } autoscale and { Y Y } logscale are now invalid;
1074: - *D is added (depth multiplication, for 3D graphics);
1075: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1076: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1077: - a major bug is fixed in GETI instrinsic when it is used with a name
1078: that contains a matrix or a vector (bad upper bounds conditions in
1079: incrementation);
1080: - DISP intrinsic now uses the 33-th flag. When it is not set
1081: (default), a final carriage return is sent to the terminal;
1082: - AXES intrinsic only takes a list that can contains the keywork
1083: "main" or "auxiliary". Before this modification, this keyword was in
1084: the first stack level;
1085: - vim syntax file is upgraded;
1086: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1087: option;
1088: - LAST is now disabled in the main loop of INT intrinsic;
1089: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1090: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1091: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1092: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1093: in 0);
1094: - LAST is disabled in the main loop of DRAW intrinsic;
1095: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1096: evaluation of an equation, the system stack is returned corrupted to the
1097: sequencer;
1098: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1099: of a loop are not integer or real.
1100: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1101: - the compilation stage aborts with an error message when two definitions
1102: have the same name. To improve the compilation() subroutine, I have to
1103: add some tests in gestion_variables.c;
1104: - recherche_type() subroutine ad some other connex subroutines are improved.
1105: Now, some syntax errors about object are caught and do not perform sequencer
1106: hangup;

1108: - Makefile.am's and configure.in scripts are improved.
1109: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1110: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1111: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1112: the boxwidth, 1 by default);
1113: - recherche_type() is rewritten to be faster;
1114: - gsl is upgraded (release 1.3);
1115: - ncurses is upgraded and patched (release 5.3);
1116: - recherche_instruction_suivante() is fixed (string research with included
1117: '"') and rewritten to be faster;
1118: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1119: segfault.
1120: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1128: - a minor bug is fixed in evaluation subroutine;
1129: - vim syntax file is improved;
1130: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1131: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1132: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1133: is a quick and dirty workaround...);
1134: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1135: - rplconvert is improved.
1136: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
