30: By default, implicit is set to "ALL";
31: - sqlite is upgraded to 3.6.23.1;
32: - openssl is upgraded to 1.0.0;
33: - major bug is fixed in RETURN intrinsic. It only occurs in evaluation
34: subroutine;
35: - table variable can now be sorted by SORT;
36: - some regressions between libtool 1.x and 2.x are fixed by workarouds in
37: Makefiles;
38: - -a command line option analyzes program (structure and syntax) and
39: sends preprocessor output to standard output. This option is used by
40: rplc (RPL/2 compiler).
41: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
42: - in formatted file, string format returned a variable length string even if
43: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
44: a variable length string and 'CHARACTER*(n)' a fixed length string;
45: - keyed access files support is added. Currently, only formatted files are
46: supported;
47: - direct access files support is added. Currenlty, these files can only be used
48: in formatted mode;
49: - virtual variables are now writte in UTF-8 and all special characters
50: in string are escaped;
51: - all formatted files are now converted into UTF-8;
52: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
53: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
54: each execution (md5 and sha1 sums) to enhance security. If one of these tools
55: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
56: on a non recoverable system error;
57: - openssl and sqlite3 libraries are added;
58: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
59: variable indicates RPL/2 root directory. If it is not set, root path
60: is given by configure script (d_exec_path);
61: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
62: - configure.in and makefile.am's are modified to add Cygwin support. Interix
63: support is broken;

68: fraction intead real one;
69: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
70: - Makefile.am are modified to authorize parallel builds;
71: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
72: and writes warning to standard output;
73: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)
74: - escape codes are now converted in formateur(), not in recherche_type() to
75: avoid a minor bug in EDIT and VISIT intrinsics;
76: - minor bug is fixed in formateur_reel();
77: - file-5.03 is patched to avoid bus error on systems that require memory
78: alignment;
79: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
80: were able to be avoided by evaluation routine.
81: * Tue Jan 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.9 (RPL/2)

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

251: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
252: process is killed;
253: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
254: know typeof() intrinsic function. This function is not standard but exists
255: under Sun Studio, gcc, and maybe some others compilers. If this function does
256: not exist on your compiler, you can change its definition by old one in

298: static variable that is shared by multiple threads;
299: - '->' intrinsic is improved. All object copies have been avoided;
300: - -n flag is added to catch HUP signal. stderr and stdout are redirected
301: to a file, stdin is redirected to /dev/null when control process is killed;
302: - a mutex is added to each object (before this modification,

319: that all programs that worked with old SQL intrinsic can now work with
320: SQLQUERY. With all new programs, you can open a real connection to databases;
321: - NRPROC is added. This new intrinsic is used to catch error from child
322: process. Without NRPROC, any errors returned by child process cause
323: main process to abort;
324: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
325: starts a new process). There are no mutexes in RPL/2 because all spawned process
326: use specific context. Nevertheless, shared variables and associated mutexes
327: should be added;

413: - FUSE, RFUSE and CLRFUSE have been added;
414: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
415: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
416: workaround for this major bug. Nevertheless, all others capabilities seems to
417: work fine;
418: - '->' is modified to return error when program tries to initialiaze two
419: variables with the same name like
420: 1 0 -> I I << ... >>;

466: before starting interrupt evaluation;
467: - -f parameter is added when iconv is called;
468: - as old file program was bugged, a new option is added to configure script.
469: When configure is called with --disable-encoding-autodetection, make does not
470: try to detect source encoding. Please, do not use if RPL/2 can be built
471: without this option !
472: - new garbage collector (and more efficient) is written;
473: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
474: not support real time signals, RPL/2 cannot use multitasking functions;

476: - -p option is added. With this option, all scripts are compiled before
477: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
478: 40% faster;
479: - read and write operations in pipe() are rewritten to be sure that such
480: operations are atomic;
481: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

675: With STATIC, next variables created by '->' are static;
676: - PROTECT and UNPROTECT are added to protect variables against write
677: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
678: versions of PROTECT and UNPROTECT that only deal with global variables
679: (see RCL/SAVE);
680: - variable management routines have been rewritten. The new ones are
681: uncompatible with the old ones. Before these changes, a local variable
682: was exported to a child subroutine, but cannot be modified into this
683: child subroutine. Now, a local variable is accessible only in its subroutine;
684: - SAVE intrinsic is added to manipulate global variables;
685: - SUSPEND is written. RPL/2 waits for a SIGCONT signal;

1005: fine...);
1006: - NOT is not correctly formatted in formateur.c:
1007: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1008: with a NOTZ function !
1009: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1063: { "automatic" nb_of_levels }
1064: { "discrete" l1 l2 l3 ... }
1065: { "incremental" start incr }
1066: { "incremental" start incr end }

1075: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1076: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1077: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1094: - SCLS is added;
1095: - DRWS now uses COLS to draw 2D graphics;
1096: - PPAR and SPAR are written. SPAR returns a list that contains the
1097: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1098: statistical variable, or "DISABLED" if its type is not one of the type of
1099: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1100: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1101: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1102: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1103: disabled. Arguments of EXTERNAL are case sensitive because the external
1104: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1105: of known external functions but add the new list to the last. { "all" }
1106: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1107: external names of the known functions;
1108: - mkrplso.in is modified.
1109: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1110: - vim syntax file is upgraded;
1111: - a minor mistake is fixed in recherche_instruction_suivante();

1120: - PUTC and PUTR new intrinsics are added.
1121: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1122: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1123: VISIT does not find a name in level 1;
1124: - configure.in script is modified to add a new test (--enable-debug
1125: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1126: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1127: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1128: 'MATRIX' { 2 2 3 } GETR;
1129: - LOGSCALE intrinsic is improved and now, it can be used as
1130: { "main" "auxiliary" X Y } LOGSCALE;
1131: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1132: same than AXES:
1133: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1134: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1135: { { -10 10 } "automatic" } SCALE.
1136: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1137: because it changes only the dimension of the screen. To have a logarithmic
1138: scale, you must use LOGSCALE intrinsic:
1139: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1140: screen on second scale;
1141: - { X X } autoscale and { Y Y } logscale are now invalid;
1142: - *D is added (depth multiplication, for 3D graphics);
1143: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1144: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1145: - a major bug is fixed in GETI instrinsic when it is used with a name
1146: that contains a matrix or a vector (bad upper bounds conditions in
1147: incrementation);
1148: - DISP intrinsic now uses the 33-th flag. When it is not set
1149: (default), a final carriage return is sent to the terminal;
1150: - AXES intrinsic only takes a list that can contains the keywork
1151: "main" or "auxiliary". Before this modification, this keyword was in
1152: the first stack level;
1153: - vim syntax file is upgraded;
1154: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1155: option;
