                     41: are first fit class allocators. Solaris libmtmalloc works better and is
                     42: a best fit class allocator but its performance is poor than ptmalloc3
                     43: performance;

                     50: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
                     51: ATEXIT. If it receives SIGFABORT, it does not;
1.23      bertrand   52: - ONEXIT is renamed in ATEXIT;

                    192: that is not offered by some iconv utility;
                    193: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
                    194: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

                    206: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
                    207: used in onLoading from shared library, USE was pushed on stack as algebraic
                    208: expression;
                    209: - libiconv is upgraded to 1.13.1;

                    213: - pipe() is overwritten by a macro to avoid a system error. Communication
                    214: between process are done with pipes and these pipes are managed by a
                    215: specific asynchrone thread. If a script try to create more threads than
                    216: management thread can destroy, you can quickly achieve maximum number of
                    217: opened files and pipe() shall return a system error. This macro tries to create
                    218: pipes. If pipe() function returns an error, macro waits and retries. If
                    219: number of retries is greater than a hardcoded value, macro returns an error;
                    220: - major bug (deadlock) is fixed in process and thread management. I hope
                    221: this bug shall be the last one;
                    222: - major bug is fixed in DET intrinsic (determinant was computed without LU
                    223: diagonalization);
                    224: - SWAPCNTXT is added;

                    229: or thread number;
                    230: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
                    231: was called before a pending interruption5 (SIGFSTOP), signal handler uses
                    232: a freed semaphore and corrupts heap;
                    233: - CLRERR is added to erase previous errors;

                    236: when semaphore_liste_threads is null to avoid deadlock. This bug only
                    237: occured when STOP was sent to a dying thread or process (when this thread or
                    238: process was running retrait_thread());
                    239: - matrix rank is computed before matrix inversion;
                    240: - file locks are added to stdin and stdout. stderr is not locked because
                    241: all messages written by signal handlers are sent to stderr;
                    242: - configure.in script is modified to test gcc version and avoid a bug in

                    367: - a mutex is added to each object (before this modification,
                    368: RPL/2 used a global mutex and performances in multithreaded programs were very
                    369: poor.);

                    384: that all programs that worked with old SQL intrinsic can now work with
                    385: SQLQUERY. With all new programs, you can open a real connection to databases;
                    386: - NRPROC is added. This new intrinsic is used to catch error from child
                    387: process. Without NRPROC, any errors returned by child process cause
                    388: main process to abort;
                    389: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
                    390: starts a new process). There are no mutexes in RPL/2 because all spawned process
                    391: use specific context. Nevertheless, shared variables and associated mutexes
                    392: should be added;

                    397: - -t flag is fixed ('\0' is missing...);
                    398: - SWI and SEND pipes have been modified to be more robust on systems where
                    399: getpid() can return (pid_t) -1 or (pid_t) -2 value;
                    400: - major bug is fixed in REPEAT intrinsic. Only occurs in compiled mode;

                   1186: * Sun Apr 13 2003 BERTRAND JoŽl <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
                   1187: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
                   1188: VISIT does not find a name in level 1;
                   1189: - configure.in script is modified to add a new test (--enable-debug
                   1190: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
                   1191: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
                   1192: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
                   1193: 'MATRIX' { 2 2 3 } GETR;
                   1194: - LOGSCALE intrinsic is improved and now, it can be used as
                   1195: { "main" "auxiliary" X Y } LOGSCALE;
                   1196: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
                   1197: same than AXES:
                   1198: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
                   1199: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
                   1200: { { -10 10 } "automatic" } SCALE.
                   1201: Warning, it is not possible to ask a logarithmic scale with this intrinsic
                   1202: because it changes only the dimension of the screen. To have a logarithmic
                   1203: scale, you must use LOGSCALE intrinsic:
                   1204: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
                   1205: screen on second scale;
                   1206: - { X X } autoscale and { Y Y } logscale are now invalid;
                   1207: - *D is added (depth multiplication, for 3D graphics);
                   1208: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
                   1209: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
                   1210: - a major bug is fixed in GETI instrinsic when it is used with a name
                   1211: that contains a matrix or a vector (bad upper bounds conditions in
                   1212: incrementation);
                   1213: - DISP intrinsic now uses the 33-th flag. When it is not set
                   1214: (default), a final carriage return is sent to the terminal;
                   1215: - AXES intrinsic only takes a list that can contains the keywork
                   1216: "main" or "auxiliary". Before this modification, this keyword was in
                   1217: the first stack level;
                   1218: - vim syntax file is upgraded;
                   1219: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
                   1220: option;
                   1221: - LAST is now disabled in the main loop of INT intrinsic;
                   1222: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.

                   1224: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
                   1225: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
                   1226: in 0);
                   1227: - LAST is disabled in the main loop of DRAW intrinsic;
                   1228: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
                   1229: evaluation of an equation, the system stack is returned corrupted to the
                   1230: sequencer;
                   1231: - the same minor bug is fixed in FOR and START. It only occurs when the limits
                   1232: of a loop are not integer or real.
                   1233: * Sun Mar 31 2003 BERTRAND JoŽl <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
                   1234: - the compilation stage aborts with an error message when two definitions
                   1235: have the same name. To improve the compilation() subroutine, I have to
                   1236: add some tests in gestion_variables.c;
                   1237: - recherche_type() subroutine ad some other connex subroutines are improved.
                   1238: Now, some syntax errors about object are caught and do not perform sequencer
                   1239: hangup;
                   1240: - readline is upgraded (minor compilation bug with recent gcc);
                   1241: - Makefile.am's and configure.in scripts are improved.
                   1242: * Fri Mar 14 2003 BERTRAND JoŽl <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
                   1243: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
                   1244: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
                   1245: the boxwidth, 1 by default);
                   1246: - recherche_type() is rewritten to be faster;
                   1247: - gsl is upgraded (release 1.3);

                   1249: - recherche_instruction_suivante() is fixed (string research with included
                   1250: '"') and rewritten to be faster;
                   1251: - appel_gnuplot() is fixed. When no graphic was available, it returned a
                   1252: segfault.

                   1265: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
                   1266: is a quick and dirty workaround...);
                   1267: - RETURN intrinsic is modified to fix a trouble in interactive mode;
