1.3 ! bertrand 2: - file-5.03 is patched to avoid bus error on system that require memory
! 3: alignment;
1.2 bertrand 4: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions

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

123: - DIAG-> and ->DIAG are added;
124: - major bug is fixed in DET intrinsic. DET is rewritten to avoid usage of
125: eigenvalues. In a first time, matrix rank is estimated to force determinant
126: to zero if matrix is rank deficient. If not, a PLU decomposition is done to
127: compute determinant;
128: - QR matrix decomposition is added;

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

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

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

222: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
223: static variable that is shared by multiple threads;
224: - '->' intrinsic is improved. All object copies have been avoided;
225: - -n flag is added to catch HUP signal. stderr and stdout are redirected
226: to a file, stdin is redirected to /dev/null when control process is killed;
227: - a mutex is added to each object (before this modification,
228: RPL/2 used a global mutex and performances in multithreaded programs were very
229: poor.);
230: - ALARM is now interruptible;
231: - both PUT and PUTI intrinsics are improved and do not copy list and table
232: when nombre_occurrences == 1;
233: - COPY intrinsic is added. Argument (that can be pointed from some objects)
234: is replaced by a new copy of itself;
235: - memory leak is fixed in sequenceur(). It only occurs when an execution error

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

265: - LINE is added;
266: - DGTIZ is added;
267: - major bug is fixed in ROW-> intrinsic (comes from new garbage collector);

303: - ->TABLE and TABLE-> intrinsics are added;
304: - major bug is fixed in recherche_type(). Only occurs when rpl executes
305: precompiled scripts;

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

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

368: Main usages of these intrinsics are in conjonction with IFERR or with
369: software interrupts;
370: - HEAD, TAIL and REVLIST intrinsics are added;
371: - function pointers have been added to function description;
372: - new analyse() routine is written. All instrinsics are now in a N-tree;

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

547: - external wrapper (rplplot) is written to force usage of gnuplot provided
548: by RPL/2 if it is built during build process. If this build does not exist,
549: it tries to launch regular gnuplot;
550: - gnuplot is added to source tree to avoid some trouble between preinstalled
551: gnuplot and release used by RPL/2. This addition to source tree is

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

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

1000: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1001: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1002: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1019: - SCLS is added;
1020: - DRWS now uses COLS to draw 2D graphics;
1021: - PPAR and SPAR are written. SPAR returns a list that contains the

1023: statistical variable, or "DISABLED" if its type is not one of the type of
1024: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1025: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1026: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1027: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1028: disabled. Arguments of EXTERNAL are case sensitive because the external
1029: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1030: of known external functions but add the new list to the last. { "all" }
1031: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1032: external names of the known functions;
1033: - mkrplso.in is modified.

1047: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1048: VISIT does not find a name in level 1;
1049: - configure.in script is modified to add a new test (--enable-debug
1050: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1051: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1052: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1053: 'MATRIX' { 2 2 3 } GETR;
1054: - LOGSCALE intrinsic is improved and now, it can be used as
1055: { "main" "auxiliary" X Y } LOGSCALE;
1056: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1057: same than AXES:
1058: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1059: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1060: { { -10 10 } "automatic" } SCALE.
1061: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1062: because it changes only the dimension of the screen. To have a logarithmic
1063: scale, you must use LOGSCALE intrinsic:
1064: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1065: screen on second scale;
1066: - { X X } autoscale and { Y Y } logscale are now invalid;
1067: - *D is added (depth multiplication, for 3D graphics);
1068: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1069: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1070: - a major bug is fixed in GETI instrinsic when it is used with a name
1071: that contains a matrix or a vector (bad upper bounds conditions in
1072: incrementation);
1073: - DISP intrinsic now uses the 33-th flag. When it is not set
1074: (default), a final carriage return is sent to the terminal;
1075: - AXES intrinsic only takes a list that can contains the keywork
1076: "main" or "auxiliary". Before this modification, this keyword was in
1077: the first stack level;
1078: - vim syntax file is upgraded;
1079: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1080: option;
1081: - LAST is now disabled in the main loop of INT intrinsic;
1082: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1083: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1084: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1085: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1086: in 0);
1087: - LAST is disabled in the main loop of DRAW intrinsic;
1088: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1089: evaluation of an equation, the system stack is returned corrupted to the
1090: sequencer;
1091: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1092: of a loop are not integer or real.
1093: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1106: - recherche_type() is rewritten to be faster;
1107: - gsl is upgraded (release 1.3);
1108: - ncurses is upgraded and patched (release 5.3);
1109: - recherche_instruction_suivante() is fixed (string research with included
1110: '"') and rewritten to be faster;

1121: - a minor bug is fixed in evaluation subroutine;
1122: - vim syntax file is improved;
1123: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1124: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1125: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1126: is a quick and dirty workaround...);
1127: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1128: - rplconvert is improved.
