2: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
3: - in formatted file, string format returned a variable length string even if
4: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
5: a variable length string and 'CHARACTER*(n') a fixed length string;
6: - keyed access files support is added. Currently, only formatted files are
7: supported;
8: - direct access files support is added. Currenlty, these files can only be used
9: in formatted mode;
10: - virtual variables are now writte in UTF-8 and all special characters
11: in string are escaped;
12: - all formatted files are now converted into UTF-8;
13: - all file and unix socket names created by RPL/2 are now UTF8 compliant;
14: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
15: each execution (md5 and sha1 sums) to enhance security. If one of these tools
16: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
17: on a non recoverable system error;
18: - openssl and sqlite3 libraries are added;
19: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
20: variable indicates RPL/2 root directory. If it is not set, root path
21: is given by configure script (d_exec_path);
22: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
23: - configure.in and makefile.am's are modified to add Cygwin support. Interix
24: support is broken;
25: - memory leak is fixed in recherche_type();
26: - TeX files are now written in UTF-8 even default locale differs;
27: - minor bug is fixed in ->STR (escaped characters);
28: - minor bug is fixed in ->Q intrinsic. Resultat is returned as integer
29: fraction intead real one;
30: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
31: - Makefile.am are modified to authorize parallel builds;
32: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
33: and writes warning to standard output;
34: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)
35: - escape codes are now converted in formateur(), not in recherche_type() to
36: avoid a minor bug in EDIT and VISIT intrinsics;
37: - minor bug is fixed in formateur_reel();
38: - file-5.03 is patched to avoid bus error on systems that require memory
39: alignment;
40: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
41: were able to be avoided by evaluation routine.
42: * Tue Jan 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.9 (RPL/2)

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

179: to be used in signal handlers;
180: - major bug (memory corruption) is fixed in COL- intrinsic;
181: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a

184: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
185: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
186: process termination);
187: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
188: its parent);
189: - a mutex to protect fork() syscall is added;

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

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

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

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

279: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
280: that all programs that worked with old SQL intrinsic can now work with
281: SQLQUERY. With all new programs, you can open a real connection to databases;
282: - NRPROC is added. This new intrinsic is used to catch error from child
283: process. Without NRPROC, any errors returned by child process cause
284: main process to abort;
285: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
286: starts a new process). There are no mutexes in RPL/2 because all spawned process
287: use specific context. Nevertheless, shared variables and associated mutexes
288: should be added;

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

374: - FUSE, RFUSE and CLRFUSE have been added;
375: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
376: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
377: workaround for this major bug. Nevertheless, all others capabilities seems to
378: work fine;

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

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

1036: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1037: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1038: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1059: statistical variable, or "DISABLED" if its type is not one of the type of
1060: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1061: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1062: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1063: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1064: disabled. Arguments of EXTERNAL are case sensitive because the external
1065: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1066: of known external functions but add the new list to the last. { "all" }
1067: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1068: external names of the known functions;
1069: - mkrplso.in is modified.

1084: VISIT does not find a name in level 1;
1085: - configure.in script is modified to add a new test (--enable-debug
1086: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1087: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1088: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1089: 'MATRIX' { 2 2 3 } GETR;
1090: - LOGSCALE intrinsic is improved and now, it can be used as
1091: { "main" "auxiliary" X Y } LOGSCALE;
1092: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1093: same than AXES:
1094: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1095: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1096: { { -10 10 } "automatic" } SCALE.
1097: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1098: because it changes only the dimension of the screen. To have a logarithmic
1099: scale, you must use LOGSCALE intrinsic:
1100: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1101: screen on second scale;
1102: - { X X } autoscale and { Y Y } logscale are now invalid;
1103: - *D is added (depth multiplication, for 3D graphics);
1104: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1105: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1106: - a major bug is fixed in GETI instrinsic when it is used with a name
1107: that contains a matrix or a vector (bad upper bounds conditions in
1108: incrementation);
1109: - DISP intrinsic now uses the 33-th flag. When it is not set
1110: (default), a final carriage return is sent to the terminal;
1111: - AXES intrinsic only takes a list that can contains the keywork
1112: "main" or "auxiliary". Before this modification, this keyword was in
1113: the first stack level;
1114: - vim syntax file is upgraded;
1115: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1116: option;
1117: - LAST is now disabled in the main loop of INT intrinsic;
1118: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1119: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1120: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1121: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1122: in 0);
1123: - LAST is disabled in the main loop of DRAW intrinsic;
1124: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1125: evaluation of an equation, the system stack is returned corrupted to the
1126: sequencer;
1127: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1128: of a loop are not integer or real.
1129: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
