11: rplc (RPL/2 compiler).
12: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
13: - in formatted file, string format returned a variable length string even if
14: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
15: a variable length string and 'CHARACTER*(n)' a fixed length string;
16: - keyed access files support is added. Currently, only formatted files are
17: supported;
18: - direct access files support is added. Currenlty, these files can only be used
19: in formatted mode;
20: - virtual variables are now writte in UTF-8 and all special characters
21: in string are escaped;
22: - all formatted files are now converted into UTF-8;
23: - all file and unix socket names created by RPL/2 are now UTF8 compliant;
24: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
25: each execution (md5 and sha1 sums) to enhance security. If one of these tools
26: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
27: on a non recoverable system error;
28: - openssl and sqlite3 libraries are added;
29: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
30: variable indicates RPL/2 root directory. If it is not set, root path
31: is given by configure script (d_exec_path);
32: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

39: fraction intead real one;
40: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
41: - Makefile.am are modified to authorize parallel builds;
42: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
43: and writes warning to standard output;
44: * Wed Feb 10 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.10 (RPL/2)

58:
59: - PULPRFL does not abort on BUG() but on execution error;
60: - TRIM, REPL and TOKENIZE are added;
61: - sockets options are now set before bind();
62: - shutdown() is added to all connected sockets;

65: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
66: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
67: signals sent to main process were not caught because DAEMON did not replace
68: old pid by new one;
69: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
70: evaluation when an error is reported from a subroutine in another subroutine.
71: For example, error was not caught in following program when it is executed with
72: -p option :
73: TEST << iferr TEST2 then end >>
74: TEST2 << 0 inv >>
75: - major bug is fixed in variable management. Some local variables were
76: seen as global ones;
77: - major bug is fixed in rplcore. Rplcore entered in dead lock when
78: script file contains a multibyte character;
79: - IN intrinsic is added;
80: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
81: returned false ;
82: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
83: programs;
84: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
85: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
86: strings were never closed;
87: - some bugs have been fixed in file management;
88: - RPL/2 can now be run on EBCDIC systems (OS/390);
89: - major bug is fixed in -A command line option (NULL character is missing);
90: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
91: made by blocks (1024 bytes). When an incomplete multibyte sequence is
92: encountered at end of block, subroutine aborts with an execution error;
93: - major bug is fixed in OPEN (TCP/IPv4 sockets).
94: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
95: - DISP now locks stdout;
96: - rpliconv is added to replace standard iconv provided by operating system.
97: Indeed, conversion between different encodages requires transliteration
98: that is not offered by some iconv utility;
99: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
100: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
101: not be found), SYSEVAL enters in a dead lock;
102: - fprintf is replaced by some functions that allow transliterations between
103: locales;
104: - '"' can now be used in strings ("\"");
105: - iconv is called with -c in preprocessor stage. It is done to write
106: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
107: - double free is fixed in liberation() (type SQL, only occurs when locale is
108: set);
109: - LOCALIZATION, UCASE and LCASE are added;
110: - major bug is fixed in EXIT intrinsic that was able to return a false
111: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
112: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
113: used in onLoading from shared library, USE was pushed on stack as algebraic
114: expression;

116: - gnuplot is upgraded to 4.2.6;
117: - gsl is upgraded to 1.13.
118: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
119: - pipe() is overwritten by a macro to avoid a system error. Communication
120: between process are done with pipes and these pipes are managed by a
121: specific asynchrone thread. If a script try to create more threads than
122: management thread can destroy, you can quickly achieve maximum number of
123: opened files and pipe() shall return a system error. This macro tries to create
124: pipes. If pipe() function returns an error, macro waits and retries. If
125: number of retries is greater than a hardcoded value, macro returns an error;
126: - major bug (deadlock) is fixed in process and thread management. I hope
127: this bug shall be the last one;
128: - major bug is fixed in DET intrinsic (determinant was computed without LU
129: diagonalization);
130: - SWAPCNTXT is added;
131: - minor bug is fixed in Makefile.am (licences rule).
132: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
133: - some bugfixes are added in process management;
134: - all process management is rewritten to avoid usage of defunct process
135: or thread number;
136: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
137: was called before a pending interruption5 (SIGFSTOP), signal handler uses
138: a freed semaphore and corrupts heap;
139: - CLRERR is added to erase previous errors;
140: - ERRN and ERRM return exception message and number;
141: - major bug is fixed in interruptions.c. All signal are now bufferised
142: when semaphore_liste_threads is null to avoid deadlock. This bug only
143: occured when STOP was sent to a dying thread or process (when this thread or
144: process was running retrait_thread());
145: - matrix rank is computed before matrix inversion;
146: - file locks are added to stdin and stdout. stderr is not locked because
147: all messages written by signal handlers are sent to stderr;
148: - configure.in script is modified to test gcc version and avoid a bug in
149: gcc older than 4.4;
150: - some benchmarks have been done :

222: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
223: process is killed;
224: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
225: know typeof() intrinsic function. This function is not standard but exists
226: under Sun Studio, gcc, and maybe some others compilers. If this function does

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

291: SQLQUERY. With all new programs, you can open a real connection to databases;
292: - NRPROC is added. This new intrinsic is used to catch error from child
293: process. Without NRPROC, any errors returned by child process cause
294: main process to abort;
295: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
296: starts a new process). There are no mutexes in RPL/2 because all spawned process
297: use specific context. Nevertheless, shared variables and associated mutexes
298: should be added;

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

447: - -p option is added. With this option, all scripts are compiled before
448: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
449: 40% faster;
450: - read and write operations in pipe() are rewritten to be sure that such
451: operations are atomic;
452: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

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

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

1069: statistical variable, or "DISABLED" if its type is not one of the type of
1070: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1071: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1072: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1073: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1074: disabled. Arguments of EXTERNAL are case sensitive because the external
1075: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1076: of known external functions but add the new list to the last. { "all" }
1077: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1078: external names of the known functions;
1079: - mkrplso.in is modified.
1080: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)

1093: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1094: VISIT does not find a name in level 1;
1095: - configure.in script is modified to add a new test (--enable-debug
1096: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1097: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1098: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1099: 'MATRIX' { 2 2 3 } GETR;
1100: - LOGSCALE intrinsic is improved and now, it can be used as
1101: { "main" "auxiliary" X Y } LOGSCALE;
1102: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1103: same than AXES:
1104: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1105: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1106: { { -10 10 } "automatic" } SCALE.
1107: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1108: because it changes only the dimension of the screen. To have a logarithmic
1109: scale, you must use LOGSCALE intrinsic:
1110: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1111: screen on second scale;
1112: - { X X } autoscale and { Y Y } logscale are now invalid;
1113: - *D is added (depth multiplication, for 3D graphics);
1114: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1115: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1116: - a major bug is fixed in GETI instrinsic when it is used with a name
1117: that contains a matrix or a vector (bad upper bounds conditions in
1118: incrementation);
1119: - DISP intrinsic now uses the 33-th flag. When it is not set
1120: (default), a final carriage return is sent to the terminal;
1121: - AXES intrinsic only takes a list that can contains the keywork
1122: "main" or "auxiliary". Before this modification, this keyword was in
1123: the first stack level;
1124: - vim syntax file is upgraded;
1125: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1126: option;
1127: - LAST is now disabled in the main loop of INT intrinsic;
1128: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1129: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1130: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1131: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1132: in 0);
1133: - LAST is disabled in the main loop of DRAW intrinsic;
1134: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1135: evaluation of an equation, the system stack is returned corrupted to the
1136: sequencer;
1137: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1138: of a loop are not integer or real.
1139: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1140: - the compilation stage aborts with an error message when two definitions
1141: have the same name. To improve the compilation() subroutine, I have to
1142: add some tests in gestion_variables.c;
1143: - recherche_type() subroutine ad some other connex subroutines are improved.
1144: Now, some syntax errors about object are caught and do not perform sequencer
