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

132: - COND and RANK are added;
133: - DIAG-> and ->DIAG are added;
134: - major bug is fixed in DET intrinsic. DET is rewritten to avoid usage of
135: eigenvalues. In a first time, matrix rank is estimated to force determinant
136: to zero if matrix is rank deficient. If not, a PLU decomposition is done to
137: compute determinant;
138: - QR matrix decomposition is added;
139: - LQ matrix decomposition is added;

146: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
147: can call twice CSTOP without RSTOP;
148: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
149: SMPHRTRYDECR, SMPHGETV).
150: * Fri Jul 24 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.4 (RPL/2)
151: - semaphore is added in interruptions.c to avoid segmentation fault when STOP
152: signal is sent to a dying thread. Some mutexes are replaced by semaphores too
153: to be used in signal handlers;
154: - major bug (memory corruption) is fixed in COL- intrinsic;
155: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
156: software interrupt was caught;
157: - rplpp man page is added.
158: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
159: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
160: process termination);
161: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
162: its parent);
163: - a mutex to protect fork() syscall is added;
164: - all mutexes are unlocked after fork() in DETACH;

170: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
171: - FORTRAN 77 file management subroutines are rewritten in pure C due to
172: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
173: in some cases (gcc/gfortran/libc/OS and arch conjonction);
174: - a memory leak is fixed in REMOVE intrinsic;
175: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
176: and due to a libmysqlclient that is not thread safe).
177: * Wen Jun 10 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.2 (RPL/2)
178: - new enhanced allocator is written for regular variables, static variables and
179: shared variables;

183: - --enable-profile flag is added to configure script. When this flag is
184: enabled, rpl is built with -pg option;
185: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
186: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
187: process is killed;
188: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
189: know typeof() intrinsic function. This function is not standard but exists
190: under Sun Studio, gcc, and maybe some others compilers. If this function does
191: not exist on your compiler, you can change its definition by old one in
192: src/rpl.h;
193: - fflush() can now be interrupted by signal (SunOS);
194: - fflush(NULL) is called before all fork() occurrences;

212: - Signal handlers are rewritten to send signal to main thread when a signal
213: is send from an external process;
214: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
215: deadlock when a huge amount of threads is launched);
216: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
217: arguments types are unsupported;
218: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
219: data are buffered. PLOT is used to draw these objects.);
220: - MARK instrinsic is added;
221: - new allocator mechanism is written;
222: - some regression bugs have been fixed, some memory leaks too.
223: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)

230: - YIELD intrinsic is added;
231: - ERRM is fixed. In some cases, ERRM uses some uninitialized pointers;
232: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
233: static variable that is shared by multiple threads;
234: - '->' intrinsic is improved. All object copies have been avoided;
235: - -n flag is added to catch HUP signal. stderr and stdout are redirected
236: to a file, stdin is redirected to /dev/null when control process is killed;
237: - a mutex is added to each object (before this modification,
238: RPL/2 used a global mutex and performances in multithreaded programs were very
239: poor.);
240: - ALARM is now interruptible;
241: - both PUT and PUTI intrinsics are improved and do not copy list and table
242: when nombre_occurrences == 1;

251: - new SQL type is added;
252: - due to a trouble in libpq in multithreaded context, SQL intrinsic is split
253: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
254: that all programs that worked with old SQL intrinsic can now work with
255: SQLQUERY. With all new programs, you can open a real connection to databases;
256: - NRPROC is added. This new intrinsic is used to catch error from child
257: process. Without NRPROC, any errors returned by child process cause
258: main process to abort;
259: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
260: starts a new process). There are no mutexes in RPL/2 because all spawned process
261: use specific context. Nevertheless, shared variables and associated mutexes
262: should be added;
263: - -D flag and DAEMONIZE intrinsic have been added;
264: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

310: on all standard locations. Tested and works on FreeBSD, Solaris and Linux
311: Debian;
312: - Tables are allowed in eval ( <[ 1 ]> 't' sto 't(1)' eval );
313: - ->TABLE and TABLE-> intrinsics are added;
314: - major bug is fixed in recherche_type(). Only occurs when rpl executes
315: precompiled scripts;

333: nullified lists;
334: - rplexternals.h is modified and improved;
335: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and
336: configure script.
337: * Mon Jun 23 2008 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.7 (RPL/2)

348: - FUSE, RFUSE and CLRFUSE have been added;
349: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
350: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
351: workaround for this major bug. Nevertheless, all others capabilities seems to
352: work fine;
353: - '->' is modified to return error when program tries to initialiaze two

379: software interrupts;
380: - HEAD, TAIL and REVLIST intrinsics are added;

406: without this option !
407: - new garbage collector (and more efficient) is written;
408: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does

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

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

1010: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1011: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1012: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1029: - SCLS is added;
1030: - DRWS now uses COLS to draw 2D graphics;
1031: - PPAR and SPAR are written. SPAR returns a list that contains the
1032: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1033: statistical variable, or "DISABLED" if its type is not one of the type of
1034: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1035: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1036: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1037: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1038: disabled. Arguments of EXTERNAL are case sensitive because the external
1039: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1040: of known external functions but add the new list to the last. { "all" }
1041: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1042: external names of the known functions;
1043: - mkrplso.in is modified.
1044: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1057: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1058: VISIT does not find a name in level 1;
1059: - configure.in script is modified to add a new test (--enable-debug
1060: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1061: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1062: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1063: 'MATRIX' { 2 2 3 } GETR;
1064: - LOGSCALE intrinsic is improved and now, it can be used as
1065: { "main" "auxiliary" X Y } LOGSCALE;
1066: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1067: same than AXES:
1068: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1069: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1070: { { -10 10 } "automatic" } SCALE.
1071: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1072: because it changes only the dimension of the screen. To have a logarithmic
1073: scale, you must use LOGSCALE intrinsic:
1074: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1075: screen on second scale;
1076: - { X X } autoscale and { Y Y } logscale are now invalid;
1077: - *D is added (depth multiplication, for 3D graphics);
1078: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1079: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1080: - a major bug is fixed in GETI instrinsic when it is used with a name
1081: that contains a matrix or a vector (bad upper bounds conditions in
1082: incrementation);
1083: - DISP intrinsic now uses the 33-th flag. When it is not set
1084: (default), a final carriage return is sent to the terminal;
1085: - AXES intrinsic only takes a list that can contains the keywork
1086: "main" or "auxiliary". Before this modification, this keyword was in
1087: the first stack level;
1088: - vim syntax file is upgraded;
1089: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1090: option;
1091: - LAST is now disabled in the main loop of INT intrinsic;
1092: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1093: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1094: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1095: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1096: in 0);
1097: - LAST is disabled in the main loop of DRAW intrinsic;
1098: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1099: evaluation of an equation, the system stack is returned corrupted to the
1100: sequencer;
1101: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1102: of a loop are not integer or real.
1103: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1104: - the compilation stage aborts with an error message when two definitions
1105: have the same name. To improve the compilation() subroutine, I have to
1106: add some tests in gestion_variables.c;
1107: - recherche_type() subroutine ad some other connex subroutines are improved.
1108: Now, some syntax errors about object are caught and do not perform sequencer
1109: hangup;
1110: - readline is upgraded (minor compilation bug with recent gcc);
1111: - Makefile.am's and configure.in scripts are improved.
1112: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1113: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1114: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1115: the boxwidth, 1 by default);
1116: - recherche_type() is rewritten to be faster;
1117: - gsl is upgraded (release 1.3);
1118: - ncurses is upgraded and patched (release 5.3);
1119: - recherche_instruction_suivante() is fixed (string research with included
1120: '"') and rewritten to be faster;
1121: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1122: segfault.
1123: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1131: - a minor bug is fixed in evaluation subroutine;
1132: - vim syntax file is improved;
1133: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1134: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1135: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1136: is a quick and dirty workaround...);
1137: - RETURN intrinsic is modified to fix a trouble in interactive mode;
