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

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

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

247: - --enable-profile flag is added to configure script. When this flag is
248: enabled, rpl is built with -pg option;
249: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
250: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
251: process is killed;
252: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
253: know typeof() intrinsic function. This function is not standard but exists
254: under Sun Studio, gcc, and maybe some others compilers. If this function does
255: not exist on your compiler, you can change its definition by old one in
256: src/rpl.h;

279: deadlock when a huge amount of threads is launched);
280: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
281: arguments types are unsupported;

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

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

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

465: before starting interrupt evaluation;
466: - -f parameter is added when iconv is called;
467: - as old file program was bugged, a new option is added to configure script.
468: When configure is called with --disable-encoding-autodetection, make does not
469: try to detect source encoding. Please, do not use if RPL/2 can be built
470: without this option !
471: - new garbage collector (and more efficient) is written;

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

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

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

1075: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1076: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

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

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