! 6: Number of scalar operations per second and per core : 2383016
! 7:
! 8: - PULPRFL does not abort on BUG() but on execution error;
! 9: - TRIM, REPL and TOKENIZE are added;
! 10: - sockets options are now set before bind();
! 11: - shutdown() is added to all connected sockets;
! 12: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
! 13: list argument and inexistant elements).
! 14: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
! 15: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
! 16: signals sent to main process were not caught because DAEMON did not replace
! 17: old pid by new one;
! 18: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
! 19: evaluation when an error is reported from a subroutine in another subroutine.
! 20: For example, error was not caught in following program when it is executed with
! 21: -p option :
! 22: TEST << iferr TEST2 then end >>
! 23: TEST2 << 0 inv >>
! 24: - major bug is fixed in variable management. Some local variables were
! 25: seen as global ones;
! 26: - major bug is fixed in rplcore. Rplcore entered in dead lock when
! 27: script file contains a multibyte character;
! 28: - IN intrinsic is added;
! 29: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
! 30: returned false ;
! 31: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
! 32: programs;
! 33: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
! 34: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
! 35: strings were never closed;
! 36: - some bugs have been fixed in file management;
! 37: - RPL/2 can now be run on EBCDIC systems (OS/390);
! 38: - major bug is fixed in -A command line option (NULL character is missing);
! 39: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
! 40: made by blocks (1024 bytes). When an incomplete multibyte sequence is
! 41: encountered at end of block, subroutine aborts with an execution error;
! 42: - major bug is fixed in OPEN (TCP/IPv4 sockets).
! 43: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
! 44: - DISP now locks stdout;
! 45: - rpliconv is added to replace standard iconv provided by operating system.
! 46: Indeed, conversion between different encodages requires transliteration
! 47: that is not offered by some iconv utility;
! 48: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
! 49: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
! 50: not be found), SYSEVAL enters in a dead lock;
! 51: - fprintf is replaced by some functions that allow transliterations between
! 52: locales;
! 53: - '"' can now be used in strings ("\"");
! 54: - iconv is called with -c in preprocessor stage. It is done to write
! 55: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
! 56: - double free is fixed in liberation() (type SQL, only occurs when locale is
! 57: set);
! 58: - LOCALIZATION, UCASE and LCASE are added;
! 59: - major bug is fixed in EXIT intrinsic that was able to return a false
! 60: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
! 61: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
! 62: used in onLoading from shared library, USE was pushed on stack as algebraic
! 63: expression;
! 64: - libiconv is upgraded to 1.13.1;
! 65: - gnuplot is upgraded to 4.2.6;
! 66: - gsl is upgraded to 1.13.
! 67: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
! 68: - pipe() is overwritten by a macro to avoid a system error. Communication
! 69: between process are done with pipes and these pipes are managed by a
! 70: specific asynchrone thread. If a script try to create more threads than
! 71: management thread can destroy, you can quickly achieve maximum number of
! 72: opened files and pipe() shall return a system error. This macro tries to create
! 73: pipes. If pipe() function returns an error, macro waits and retries. If
! 74: number of retries is greater than a hardcoded value, macro returns an error;
! 75: - major bug (deadlock) is fixed in process and thread management. I hope
! 76: this bug shall be the last one;
! 77: - major bug is fixed in DET intrinsic (determinant was computed without LU
! 78: diagonalization);
! 79: - SWAPCNTXT is added;
! 80: - minor bug is fixed in Makefile.am (licences rule).
! 81: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
! 82: - some bugfixes are added in process management;
! 83: - all process management is rewritten to avoid usage of defunct process
! 84: or thread number;
! 85: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
! 86: was called before a pending interruption5 (SIGFSTOP), signal handler uses
! 87: a freed semaphore and corrupts heap;
! 88: - CLRERR is added to erase previous errors;
! 89: - ERRN and ERRM return exception message and number;
! 90: - major bug is fixed in interruptions.c. All signal are now bufferised
! 91: when semaphore_liste_threads is null to avoid deadlock. This bug only
! 92: occured when STOP was sent to a dying thread or process (when this thread or
! 93: process was running retrait_thread());
! 94: - matrix rank is computed before matrix inversion;
! 95: - file locks are added to stdin and stdout. stderr is not locked because
! 96: all messages written by signal handlers are sent to stderr;
! 97: - configure.in script is modified to test gcc version and avoid a bug in
! 98: gcc older than 4.4;
! 99: - some benchmarks have been done :

! 133: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
! 134: SMPHRTRYDECR, SMPHGETV).
! 135: * Fri Jul 24 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.4 (RPL/2)
! 136: - semaphore is added in interruptions.c to avoid segmentation fault when STOP
! 137: signal is sent to a dying thread. Some mutexes are replaced by semaphores too
! 138: to be used in signal handlers;
! 139: - major bug (memory corruption) is fixed in COL- intrinsic;

! 144: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
! 145: process termination);
! 146: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
! 147: its parent);
! 148: - a mutex to protect fork() syscall is added;
! 149: - all mutexes are unlocked after fork() in DETACH;
! 150: - minor bug (double free corruption) is fixed in CLOSE intrinsic;
! 151: - major bug is fixed in lecture_pipe when a nullified list is sent into a pipe;

! 155: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
! 156: - FORTRAN 77 file management subroutines are rewritten in pure C due to
! 157: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
! 158: in some cases (gcc/gfortran/libc/OS and arch conjonction);
! 159: - a memory leak is fixed in REMOVE intrinsic;
! 160: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
! 161: and due to a libmysqlclient that is not thread safe).
! 162: * Wen Jun 10 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.2 (RPL/2)
! 163: - new enhanced allocator is written for regular variables, static variables and
! 164: shared variables;

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

! 199: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
! 200: deadlock when a huge amount of threads is launched);
! 201: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
! 202: arguments types are unsupported;
! 203: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

! 213: See README for more explanations;
! 214: - MTXSTATUS intrinsic is added;
! 215: - YIELD intrinsic is added;
! 216: - ERRM is fixed. In some cases, ERRM uses some uninitialized pointers;
! 217: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
! 218: static variable that is shared by multiple threads;
! 219: - '->' intrinsic is improved. All object copies have been avoided;
! 220: - -n flag is added to catch HUP signal. stderr and stdout are redirected
! 221: to a file, stdin is redirected to /dev/null when control process is killed;
! 222: - a mutex is added to each object (before this modification,
! 223: RPL/2 used a global mutex and performances in multithreaded programs were very
! 224: poor.);
! 225: - ALARM is now interruptible;
! 226: - both PUT and PUTI intrinsics are improved and do not copy list and table
! 227: when nombre_occurrences == 1;
! 228: - COPY intrinsic is added. Argument (that can be pointed from some objects)
! 229: is replaced by a new copy of itself;

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

! 264: it's done. Data integrity is now respected during transmission (POKE, SEND and
! 265: SWI);
! 266: - ITRACE is added. This intrinsic is only used to debug internal structures and
! 267: should not be used in regular programs;
! 268: - SWISTATUS is written;
! 269: - WFACK is written;
! 270: - rplcore files are now able to handle compilation errors;
! 271: - rplcore files are now able to handle evaluation and interruption errors;

! 363: Main usages of these intrinsics are in conjonction with IFERR or with
! 364: software interrupts;
! 365: - HEAD, TAIL and REVLIST intrinsics are added;
! 366: - function pointers have been added to function description;
! 367: - new analyse() routine is written. All instrinsics are now in a N-tree;

! 375: '-' intrinsics;
! 376: - PostgreSQL support is written.

! 378: - locale can now be specified in SQL intrinsic :
! 379: { "mysql:iso-8859-1" "server" "database" ... };
! 380: - major bug is fixed un analyse_algebrique(). When DISP printed an algebraic

! 391: without this option !
! 392: - new garbage collector (and more efficient) is written;
! 393: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
! 394: not support real time signals, RPL/2 cannot use multitasking functions;
! 395: - error returned by preprocessor are now catched by RPL/2;
! 396: - -p option is added. With this option, all scripts are compiled before
! 397: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
! 398: 40% faster;
! 399: - read and write operations in pipe() are rewritten to be sure that such
! 400: operations are atomic;

! 595: With STATIC, next variables created by '->' are static;
! 596: - PROTECT and UNPROTECT are added to protect variables against write
! 597: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
! 598: versions of PROTECT and UNPROTECT that only deal with global variables
! 599: (see RCL/SAVE);
! 600: - variable management routines have been rewritten. The new ones are
! 601: uncompatible with the old ones. Before these changes, a local variable
! 602: was exported to a child subroutine, but cannot be modified into this
! 603: child subroutine. Now, a local variable is accessible only in its subroutine;
! 604: - SAVE intrinsic is added to manipulate global variables;

! 927: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
! 928: with a NOTZ function !
! 929: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

! 932: - RPL/2 is tested with efence and valgrind;
! 933: - configure.in script is modified;
! 934: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
! 935: structure. I don't know why this code was compiled by gcc-3.3... Maybe

! 995: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
! 996: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
! 997: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
! 998: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

! 1014: - SCLS is added;
! 1015: - DRWS now uses COLS to draw 2D graphics;
! 1016: - PPAR and SPAR are written. SPAR returns a list that contains the
! 1017: size of the statistical matrix (or "UNAVALAIBLE" if there is any
! 1018: statistical variable, or "DISABLED" if its type is not one of the type of
! 1019: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
! 1020: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
! 1021: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
! 1022: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
! 1023: disabled. Arguments of EXTERNAL are case sensitive because the external
! 1024: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
! 1025: of known external functions but add the new list to the last. { "all" }
! 1026: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
! 1027: external names of the known functions;
! 1028: - mkrplso.in is modified.
! 1029: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
! 1030: - vim syntax file is upgraded;
! 1031: - a minor mistake is fixed in recherche_instruction_suivante();

! 1042: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
! 1043: VISIT does not find a name in level 1;
! 1044: - configure.in script is modified to add a new test (--enable-debug
! 1045: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
! 1046: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
! 1047: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
! 1048: 'MATRIX' { 2 2 3 } GETR;
! 1049: - LOGSCALE intrinsic is improved and now, it can be used as
! 1050: { "main" "auxiliary" X Y } LOGSCALE;
! 1051: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
! 1052: same than AXES:
! 1053: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
! 1054: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
! 1055: { { -10 10 } "automatic" } SCALE.
! 1056: Warning, it is not possible to ask a logarithmic scale with this intrinsic
! 1057: because it changes only the dimension of the screen. To have a logarithmic
! 1058: scale, you must use LOGSCALE intrinsic:
! 1059: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
! 1060: screen on second scale;
! 1061: - { X X } autoscale and { Y Y } logscale are now invalid;
! 1062: - *D is added (depth multiplication, for 3D graphics);
! 1063: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
! 1064: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
! 1065: - a major bug is fixed in GETI instrinsic when it is used with a name
! 1066: that contains a matrix or a vector (bad upper bounds conditions in
! 1067: incrementation);
! 1068: - DISP intrinsic now uses the 33-th flag. When it is not set
! 1069: (default), a final carriage return is sent to the terminal;
! 1070: - AXES intrinsic only takes a list that can contains the keywork
! 1071: "main" or "auxiliary". Before this modification, this keyword was in
! 1072: the first stack level;
! 1073: - vim syntax file is upgraded;
! 1074: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
! 1075: option;
! 1076: - LAST is now disabled in the main loop of INT intrinsic;
! 1077: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
! 1078: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
! 1079: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
! 1080: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
! 1081: in 0);
! 1082: - LAST is disabled in the main loop of DRAW intrinsic;
! 1083: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
! 1084: evaluation of an equation, the system stack is returned corrupted to the
! 1085: sequencer;
! 1086: - the same minor bug is fixed in FOR and START. It only occurs when the limits
! 1087: of a loop are not integer or real.
! 1088: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
! 1089: - the compilation stage aborts with an error message when two definitions
! 1090: have the same name. To improve the compilation() subroutine, I have to
! 1091: add some tests in gestion_variables.c;
! 1092: - recherche_type() subroutine ad some other connex subroutines are improved.
! 1093: Now, some syntax errors about object are caught and do not perform sequencer
! 1094: hangup;
! 1095: - readline is upgraded (minor compilation bug with recent gcc);
! 1096: - Makefile.am's and configure.in scripts are improved.
