6: Number of scalar operations per second and per core : 2383016
7:
8: - PULPRFL does not abort on BUG() but on execution error;
9: - TRIM, REPL and TOKENIZE are added;
10: - sockets options are now set before bind();
11: - shutdown() is added to all connected sockets;
12: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
13: list argument and inexistant elements).
14: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
15: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
16: signals sent to main process were not caught because DAEMON did not replace
17: old pid by new one;
18: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
19: evaluation when an error is reported from a subroutine in another subroutine.
20: For example, error was not caught in following program when it is executed with
21: -p option :
22: TEST << iferr TEST2 then end >>
23: TEST2 << 0 inv >>
24: - major bug is fixed in variable management. Some local variables were
25: seen as global ones;
26: - major bug is fixed in rplcore. Rplcore entered in dead lock when
27: script file contains a multibyte character;
28: - IN intrinsic is added;
29: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
30: returned false ;
31: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
32: programs;
33: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
34: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
35: strings were never closed;
36: - some bugs have been fixed in file management;
37: - RPL/2 can now be run on EBCDIC systems (OS/390);
38: - major bug is fixed in -A command line option (NULL character is missing);
39: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
40: made by blocks (1024 bytes). When an incomplete multibyte sequence is
41: encountered at end of block, subroutine aborts with an execution error;
42: - major bug is fixed in OPEN (TCP/IPv4 sockets).
43: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
44: - DISP now locks stdout;
45: - rpliconv is added to replace standard iconv provided by operating system.
46: Indeed, conversion between different encodages requires transliteration
47: that is not offered by some iconv utility;
48: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
49: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
50: not be found), SYSEVAL enters in a dead lock;
51: - fprintf is replaced by some functions that allow transliterations between
52: locales;
53: - '"' can now be used in strings ("\"");
54: - iconv is called with -c in preprocessor stage. It is done to write
55: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
56: - double free is fixed in liberation() (type SQL, only occurs when locale is
57: set);
58: - LOCALIZATION, UCASE and LCASE are added;
59: - major bug is fixed in EXIT intrinsic that was able to return a false
60: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
61: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
62: used in onLoading from shared library, USE was pushed on stack as algebraic
63: expression;
64: - libiconv is upgraded to 1.13.1;
65: - gnuplot is upgraded to 4.2.6;
66: - gsl is upgraded to 1.13.
67: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
68: - pipe() is overwritten by a macro to avoid a system error. Communication
69: between process are done with pipes and these pipes are managed by a
70: specific asynchrone thread. If a script try to create more threads than
71: management thread can destroy, you can quickly achieve maximum number of
72: opened files and pipe() shall return a system error. This macro tries to create
73: pipes. If pipe() function returns an error, macro waits and retries. If
74: number of retries is greater than a hardcoded value, macro returns an error;
75: - major bug (deadlock) is fixed in process and thread management. I hope
76: this bug shall be the last one;
77: - major bug is fixed in DET intrinsic (determinant was computed without LU
78: diagonalization);
79: - SWAPCNTXT is added;
80: - minor bug is fixed in Makefile.am (licences rule).
81: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
82: - some bugfixes are added in process management;
83: - all process management is rewritten to avoid usage of defunct process
84: or thread number;
85: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
86: was called before a pending interruption5 (SIGFSTOP), signal handler uses
87: a freed semaphore and corrupts heap;
88: - CLRERR is added to erase previous errors;
89: - ERRN and ERRM return exception message and number;
90: - major bug is fixed in interruptions.c. All signal are now bufferised
91: when semaphore_liste_threads is null to avoid deadlock. This bug only
92: occured when STOP was sent to a dying thread or process (when this thread or
93: process was running retrait_thread());
94: - matrix rank is computed before matrix inversion;
95: - file locks are added to stdin and stdout. stderr is not locked because
96: all messages written by signal handlers are sent to stderr;
97: - configure.in script is modified to test gcc version and avoid a bug in
98: gcc older than 4.4;
99: - some benchmarks have been done :

117: - COND and RANK are added;
118: - DIAG-> and ->DIAG are added;
119: - major bug is fixed in DET intrinsic. DET is rewritten to avoid usage of
120: eigenvalues. In a first time, matrix rank is estimated to force determinant
121: to zero if matrix is rank deficient. If not, a PLU decomposition is done to
122: compute determinant;
123: - QR matrix decomposition is added;
124: - LQ matrix decomposition is added;
125: - Fortran90 files are rewritten to use Fortran2003 bind(C) statement and

128: -Wno-unused-parameter;
129: - all mathematical exceptions are now signaled by exceptions instead of
130: execution error;
131: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
132: can call twice CSTOP without RSTOP;
133: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
134: SMPHRTRYDECR, SMPHGETV).
135: * Fri Jul 24 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.4 (RPL/2)
136: - semaphore is added in interruptions.c to avoid segmentation fault when STOP
137: signal is sent to a dying thread. Some mutexes are replaced by semaphores too
138: to be used in signal handlers;
139: - major bug (memory corruption) is fixed in COL- intrinsic;
140: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
141: software interrupt was caught;
142: - rplpp man page is added.
143: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
144: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
145: process termination);
146: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
147: its parent);
148: - a mutex to protect fork() syscall is added;
149: - all mutexes are unlocked after fork() in DETACH;
150: - minor bug (double free corruption) is fixed in CLOSE intrinsic;
151: - major bug is fixed in lecture_pipe when a nullified list is sent into a pipe;

154: there variables are not modifiable and only contains static user definitions;
155: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
156: - FORTRAN 77 file management subroutines are rewritten in pure C due to
157: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
158: in some cases (gcc/gfortran/libc/OS and arch conjonction);
159: - a memory leak is fixed in REMOVE intrinsic;
160: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
161: and due to a libmysqlclient that is not thread safe).
162: * Wen Jun 10 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.2 (RPL/2)
163: - new enhanced allocator is written for regular variables, static variables and
164: shared variables;
165: - major bug is fixed in src/interruptions.c. This file did not compile
166: when SQL support was not enabled;
167: - new allocator is written for system stack and last stack;
168: - --enable-profile flag is added to configure script. When this flag is
169: enabled, rpl is built with -pg option;
170: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
171: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
172: process is killed;
173: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
174: know typeof() intrinsic function. This function is not standard but exists
175: under Sun Studio, gcc, and maybe some others compilers. If this function does
176: not exist on your compiler, you can change its definition by old one in
177: src/rpl.h;
178: - fflush() can now be interrupted by signal (SunOS);
179: - fflush(NULL) is called before all fork() occurrences;
180: - generators returned by RDGN help are sorted;

197: - Signal handlers are rewritten to send signal to main thread when a signal
198: is send from an external process;
199: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
200: deadlock when a huge amount of threads is launched);
201: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
202: arguments types are unsupported;
203: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
204: data are buffered. PLOT is used to draw these objects.);
205: - MARK instrinsic is added;
206: - new allocator mechanism is written;
207: - some regression bugs have been fixed, some memory leaks too.
208: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)
209: - an estimation of future stack elements is added to avoid some costly memory
210: allocations. This function has a positive impact on execution speed;
211: - PSHPRFL and PULPRFL have been added;
212: - RPL/2 can be built on Solaris 64 bits with some minor scripts alterations.
213: See README for more explanations;
214: - MTXSTATUS intrinsic is added;
215: - YIELD intrinsic is added;
216: - ERRM is fixed. In some cases, ERRM uses some uninitialized pointers;
217: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
218: static variable that is shared by multiple threads;
219: - '->' intrinsic is improved. All object copies have been avoided;
220: - -n flag is added to catch HUP signal. stderr and stdout are redirected
221: to a file, stdin is redirected to /dev/null when control process is killed;
222: - a mutex is added to each object (before this modification,
223: RPL/2 used a global mutex and performances in multithreaded programs were very
224: poor.);
225: - ALARM is now interruptible;
226: - both PUT and PUTI intrinsics are improved and do not copy list and table
227: when nombre_occurrences == 1;
228: - COPY intrinsic is added. Argument (that can be pointed from some objects)
229: is replaced by a new copy of itself;
230: - memory leak is fixed in sequenceur(). It only occurs when an execution error

234: - profile statistics have been added. See -P option;
235: - major bug is fixed in analyse_syntaxique();
236: - new SQL type is added;
237: - due to a trouble in libpq in multithreaded context, SQL intrinsic is split
238: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
239: that all programs that worked with old SQL intrinsic can now work with
240: SQLQUERY. With all new programs, you can open a real connection to databases;
241: - NRPROC is added. This new intrinsic is used to catch error from child
242: process. Without NRPROC, any errors returned by child process cause
243: main process to abort;
244: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
245: starts a new process). There are no mutexes in RPL/2 because all spawned process
246: use specific context. Nevertheless, shared variables and associated mutexes
247: should be added;
248: - -D flag and DAEMONIZE intrinsic have been added;
249: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

294: - configure script is modified to check mysql and postgresql libraries
295: on all standard locations. Tested and works on FreeBSD, Solaris and Linux
296: Debian;
297: - Tables are allowed in eval ( <[ 1 ]> 't' sto 't(1)' eval );
298: - ->TABLE and TABLE-> intrinsics are added;
299: - major bug is fixed in recherche_type(). Only occurs when rpl executes
300: precompiled scripts;

317: CRTAB new intrinsic creates a regular table. By default, all elements are
318: nullified lists;
319: - rplexternals.h is modified and improved;
320: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and
321: configure script.
322: * Mon Jun 23 2008 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.7 (RPL/2)
323: - libiconv is added (iconv library exists on some systems but implemantations
324: differ and RPL/2 can crash);

333: - FUSE, RFUSE and CLRFUSE have been added;
334: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
335: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
336: workaround for this major bug. Nevertheless, all others capabilities seems to
337: work fine;
338: - '->' is modified to return error when program tries to initialiaze two
339: variables with the same name like

352: - SIGPIPE signal handler is modified to avoid abort process when POKE tries
353: to write data into a pipe without reader;
354: - major bug is fixed in RETURN intrinsic. When RETURN was called from a detached
355: process without -p modifier, it can send an ABORT signal instead a KILL one;
356: - PEEK, POKE and WFPOKE new intrinsics are written;
357: - major bug due to new garbage collector is fixed in rplexternals.h (double free
358: corruption);

360: - VERIFY intrinsic is written;
361: - PSHCNTXT and PULCNTXT are added (PSHCNTXT pushes context on an
362: internal contexts stack, PULCNTXT pulls contexts from this internal stack).
363: Main usages of these intrinsics are in conjonction with IFERR or with
364: software interrupts;
365: - HEAD, TAIL and REVLIST intrinsics are added;
366: - function pointers have been added to function description;
367: - new analyse() routine is written. All instrinsics are now in a N-tree;

369: - multitasking capabilities have been modified to be usable on NetBSD. All real
370: time signals have been removed;
371: - major bugs are fixed in multitasking (mutex trouble _and_ segmentation fault);
372: - minor bug is fixed in STR->. STR-> could return a system error instead an
373: execution one;
374: - first bug due to new garbage collector is fixed in '+' ({ } { } +) and in
375: '-' intrinsics;
376: - PostgreSQL support is written.
377: * Mon Mar 17 2008 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.5 (RPL/2)
378: - locale can now be specified in SQL intrinsic :
379: { "mysql:iso-8859-1" "server" "database" ... };
380: - major bug is fixed un analyse_algebrique(). When DISP printed an algebraic
381: object, 'DISP()' was pushed in stack;
382: - same major bug is fixed in <, >, <=, >= and <>;
383: - major bug fixed in formateur() (segfault when a symbol is used without "'");
384: - major bug is fixed in DUPN intrinsic;
385: - when software interrupt (SWI) is evaluated, SWI pushs process id on stack
386: before starting interrupt evaluation;
387: - -f parameter is added when iconv is called;
388: - as old file program was bugged, a new option is added to configure script.
389: When configure is called with --disable-encoding-autodetection, make does not
390: try to detect source encoding. Please, do not use if RPL/2 can be built
391: without this option !
392: - new garbage collector (and more efficient) is written;
393: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
394: not support real time signals, RPL/2 cannot use multitasking functions;
395: - error returned by preprocessor are now catched by RPL/2;
396: - -p option is added. With this option, all scripts are compiled before
397: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
398: 40% faster;

544: it tries to launch regular gnuplot;
545: - gnuplot is added to source tree to avoid some trouble between preinstalled
546: gnuplot and release used by RPL/2. This addition to source tree is

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

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

1014: - SCLS is added;
1015: - DRWS now uses COLS to draw 2D graphics;
1016: - PPAR and SPAR are written. SPAR returns a list that contains the
1017: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1018: statistical variable, or "DISABLED" if its type is not one of the type of
1019: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1020: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1021: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1022: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1023: disabled. Arguments of EXTERNAL are case sensitive because the external
1024: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1025: of known external functions but add the new list to the last. { "all" }
1026: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1027: external names of the known functions;
1028: - mkrplso.in is modified.
1029: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1030: - vim syntax file is upgraded;
1031: - a minor mistake is fixed in recherche_instruction_suivante();

1042: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1043: VISIT does not find a name in level 1;
1044: - configure.in script is modified to add a new test (--enable-debug
1045: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1046: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1047: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1048: 'MATRIX' { 2 2 3 } GETR;
1049: - LOGSCALE intrinsic is improved and now, it can be used as
1050: { "main" "auxiliary" X Y } LOGSCALE;
1051: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1052: same than AXES:
1053: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1054: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1055: { { -10 10 } "automatic" } SCALE.
1056: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1057: because it changes only the dimension of the screen. To have a logarithmic
1058: scale, you must use LOGSCALE intrinsic:
1059: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1060: screen on second scale;
1061: - { X X } autoscale and { Y Y } logscale are now invalid;
1062: - *D is added (depth multiplication, for 3D graphics);
1063: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1064: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1065: - a major bug is fixed in GETI instrinsic when it is used with a name
1066: that contains a matrix or a vector (bad upper bounds conditions in
1067: incrementation);
1068: - DISP intrinsic now uses the 33-th flag. When it is not set
1069: (default), a final carriage return is sent to the terminal;
1070: - AXES intrinsic only takes a list that can contains the keywork
1071: "main" or "auxiliary". Before this modification, this keyword was in
1072: the first stack level;
1073: - vim syntax file is upgraded;
1074: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1075: option;
1076: - LAST is now disabled in the main loop of INT intrinsic;
1077: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1078: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1079: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1080: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1081: in 0);
1082: - LAST is disabled in the main loop of DRAW intrinsic;
1083: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1084: evaluation of an equation, the system stack is returned corrupted to the
1085: sequencer;
1086: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1087: of a loop are not integer or real.
1088: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1096: - Makefile.am's and configure.in scripts are improved.
1097: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1098: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1099: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1101: - recherche_type() is rewritten to be faster;
1102: - gsl is upgraded (release 1.3);
1103: - ncurses is upgraded and patched (release 5.3);
1104: - recherche_instruction_suivante() is fixed (string research with included
1105: '"') and rewritten to be faster;

1116: - a minor bug is fixed in evaluation subroutine;
1117: - vim syntax file is improved;
1118: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1119: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1120: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1121: is a quick and dirty workaround...);
1122: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1123: - rplconvert is improved.
