3: avoid a minor bug in EDIT and VISIT intrinsics;
4: - minor bug is fixed in formateur_reel();
5: - file-5.03 is patched to avoid bus error on system that require memory
6: alignment;
7: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions

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

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

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

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

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

394: before starting interrupt evaluation;
395: - -f parameter is added when iconv is called;
396: - as old file program was bugged, a new option is added to configure script.
397: When configure is called with --disable-encoding-autodetection, make does not
398: try to detect source encoding. Please, do not use if RPL/2 can be built
399: without this option !
400: - new garbage collector (and more efficient) is written;

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

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

1003: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1004: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1005: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1022: - SCLS is added;
1023: - DRWS now uses COLS to draw 2D graphics;
1024: - PPAR and SPAR are written. SPAR returns a list that contains the

1026: statistical variable, or "DISABLED" if its type is not one of the type of
1027: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1028: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1029: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1030: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1031: disabled. Arguments of EXTERNAL are case sensitive because the external
1032: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1033: of known external functions but add the new list to the last. { "all" }
1034: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1035: external names of the known functions;
1036: - mkrplso.in is modified.

1051: VISIT does not find a name in level 1;
1052: - configure.in script is modified to add a new test (--enable-debug
1053: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1054: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1055: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1056: 'MATRIX' { 2 2 3 } GETR;
1057: - LOGSCALE intrinsic is improved and now, it can be used as
1058: { "main" "auxiliary" X Y } LOGSCALE;
1059: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1060: same than AXES:
1061: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1062: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1063: { { -10 10 } "automatic" } SCALE.
1064: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1065: because it changes only the dimension of the screen. To have a logarithmic
1066: scale, you must use LOGSCALE intrinsic:
1067: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1068: screen on second scale;
1069: - { X X } autoscale and { Y Y } logscale are now invalid;
1070: - *D is added (depth multiplication, for 3D graphics);
1071: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1072: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1073: - a major bug is fixed in GETI instrinsic when it is used with a name
1074: that contains a matrix or a vector (bad upper bounds conditions in
1075: incrementation);
1076: - DISP intrinsic now uses the 33-th flag. When it is not set
1077: (default), a final carriage return is sent to the terminal;
1078: - AXES intrinsic only takes a list that can contains the keywork
1079: "main" or "auxiliary". Before this modification, this keyword was in
1080: the first stack level;
1081: - vim syntax file is upgraded;
1082: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1083: option;
1084: - LAST is now disabled in the main loop of INT intrinsic;
1085: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1086: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1087: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1088: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1089: in 0);
1090: - LAST is disabled in the main loop of DRAW intrinsic;
1091: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1092: evaluation of an equation, the system stack is returned corrupted to the
1093: sequencer;
1094: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1095: of a loop are not integer or real.
1096: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1109: - recherche_type() is rewritten to be faster;
1110: - gsl is upgraded (release 1.3);
1111: - ncurses is upgraded and patched (release 5.3);
1112: - recherche_instruction_suivante() is fixed (string research with included
1113: '"') and rewritten to be faster;

1124: - a minor bug is fixed in evaluation subroutine;
1125: - vim syntax file is improved;
1126: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1127: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1128: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1129: is a quick and dirty workaround...);
1130: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1131: - rplconvert is improved.
