2: - minor bug is fixed in formateur_reel();
3: - file-5.03 is patched to avoid bus error on system that require memory
4: alignment;
5: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
6: were able to be avoided by evaluation routine.

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

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

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

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

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

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

379: execution one;
380: - first bug due to new garbage collector is fixed in '+' ({ } { } +) and in
381: '-' intrinsics;
382: - PostgreSQL support is written.

391: - when software interrupt (SWI) is evaluated, SWI pushs process id on stack
392: before starting interrupt evaluation;
393: - -f parameter is added when iconv is called;
394: - as old file program was bugged, a new option is added to configure script.
395: When configure is called with --disable-encoding-autodetection, make does not
396: try to detect source encoding. Please, do not use if RPL/2 can be built
397: without this option !
398: - new garbage collector (and more efficient) is written;
399: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does

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

1001: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1002: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1003: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1021: - DRWS now uses COLS to draw 2D graphics;
1022: - PPAR and SPAR are written. SPAR returns a list that contains the

1024: statistical variable, or "DISABLED" if its type is not one of the type of
1025: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1026: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1027: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1028: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1029: disabled. Arguments of EXTERNAL are case sensitive because the external
1030: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1031: of known external functions but add the new list to the last. { "all" }
1032: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1033: external names of the known functions;
1034: - mkrplso.in is modified.

1049: VISIT does not find a name in level 1;
1050: - configure.in script is modified to add a new test (--enable-debug
1051: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1052: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1053: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1054: 'MATRIX' { 2 2 3 } GETR;
1055: - LOGSCALE intrinsic is improved and now, it can be used as
1056: { "main" "auxiliary" X Y } LOGSCALE;
1057: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1058: same than AXES:
1059: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1060: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1061: { { -10 10 } "automatic" } SCALE.
1062: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1063: because it changes only the dimension of the screen. To have a logarithmic
1064: scale, you must use LOGSCALE intrinsic:
1065: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1066: screen on second scale;
1067: - { X X } autoscale and { Y Y } logscale are now invalid;
1068: - *D is added (depth multiplication, for 3D graphics);
1069: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1070: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1071: - a major bug is fixed in GETI instrinsic when it is used with a name
1072: that contains a matrix or a vector (bad upper bounds conditions in
1073: incrementation);
1074: - DISP intrinsic now uses the 33-th flag. When it is not set
1075: (default), a final carriage return is sent to the terminal;
1076: - AXES intrinsic only takes a list that can contains the keywork
1077: "main" or "auxiliary". Before this modification, this keyword was in
1078: the first stack level;
1079: - vim syntax file is upgraded;
1080: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1081: option;
1082: - LAST is now disabled in the main loop of INT intrinsic;
1083: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1084: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1085: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1086: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1087: in 0);
1088: - LAST is disabled in the main loop of DRAW intrinsic;
1089: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1090: evaluation of an equation, the system stack is returned corrupted to the
1091: sequencer;
1092: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1093: of a loop are not integer or real.
1094: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1125: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1126: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1127: is a quick and dirty workaround...);
1128: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1129: - rplconvert is improved.
