Communication 367: between process are done with pipes and these pipes are managed by a 368: specific asynchrone thread. If a script try to create more threads than 369: management thread can destroy, you can quickly achieve maximum number of 370: opened files and pipe() shall return a system error. This macro tries to create 371: pipes. If pipe() function returns an error, macro waits and retries. If 372: number of retries is greater than a hardcoded value, macro returns an error; 373: - major bug (deadlock) is fixed in process and thread management.

It purges all global variables; 1213: - BESSEL intrinsic is fixed to allow the use of expressions as arguments; 1214: - a major bug was introduced with rpl-4.00pre7d in formateur.c. It appears 1215: when an algebraic expression is displayed or printed but does not affect 1216: computations. It is now fixed; 1217: - gsl is upgraded to 1.4. 1218: * Mon Aug 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7d (RPL/2) 1219: - algebraic expressions are now more readable when they are displayed 1220: (less parenthesis); 1221: - rplpp is modified to workaround a mistake in 'which' function (seems to appear 1222: on Debian distribution, but since cpp is in the default path, RPL/2 works 1223: fine...); 1224: - NOT is not correctly formatted in formateur.c: 1225: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A' 1226: with a NOTZ function ! 1227: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2) 1228: - CYCLE is fixed.

Warning: [[]] SIZE 1318: returns { 1 0 } and it is not a bug, because a null matrix contains _one_ 1319: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 }; 1320: - EXTERNAL intrinsic is added. Warning: by default, extern functions are 1321: disabled. Arguments of EXTERNAL are case sensitive because the external 1322: interface is written in C. { ext_sinus } EXTERNAL does not replace the list 1323: of known external functions but add the new list to the last. { "all" } 1324: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all 1325: external names of the known functions; 1326: - mkrplso.in is modified. 1327: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2) 1328: - vim syntax file is upgraded; 1329: - a minor mistake is fixed in recherche_instruction_suivante(); 1330: - some minor memory leaks are fixed in recherche_type() function.

To have a logarithmic 1356: scale, you must use LOGSCALE intrinsic: 1357: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log 1358: screen on second scale; 1359: - { X X } autoscale and { Y Y } logscale are now invalid; 1360: - *D is added (depth multiplication, for 3D graphics); 1361: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y 1362: and Z axes). The result of *S is the same than DUP DUP *H *W *D; 1363: - a major bug is fixed in GETI instrinsic when it is used with a name 1364: that contains a matrix or a vector (bad upper bounds conditions in 1365: incrementation); 1366: - DISP intrinsic now uses the 33-th flag. When it is not set 1367: (default), a final carriage return is sent to the terminal; 1368: - AXES intrinsic only takes a list that can contains the keywork 1369: "main" or "auxiliary". Before this modification, this keyword was in 1370: the first stack level; 1371: - vim syntax file is upgraded; 1372: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise 1373: option; 1374: - LAST is now disabled in the main loop of INT intrinsic; 1375: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h. 1376: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2) 1377: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW 1378: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X' 1379: in 0); 1380: - LAST is disabled in the main loop of DRAW intrinsic; 1381: - a major bug is fixed in DRAW intrinsic. When an error occurs in the 1382: evaluation of an equation, the system stack is returned corrupted to the 1383: sequencer; 1384: - the same minor bug is fixed in FOR and START. It only occurs when the limits 1385: of a loop are not integer or real. 1386: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2) 1387: - the compilation stage aborts with an error message when two definitions 1388: have the same name. To improve the compilation() subroutine, I have to 1389: add some tests in gestion_variables.c; 1390: - recherche_type() subroutine ad some other connex subroutines are improved. 1391: Now, some syntax errors about object are caught and do not perform sequencer 1392: hangup; 1393: - readline is upgraded (minor compilation bug with recent gcc); 1394: - Makefile.am's and configure.in scripts are improved. 1395: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2) 1396: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D 1397: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown 1398: the boxwidth, 1 by default); 1399: - recherche_type() is rewritten to be faster; 1400: - gsl is upgraded (release 1.3); 1401: - ncurses is upgraded and patched (release 5.3); 1402: - recherche_instruction_suivante() is fixed (string research with included 1403: '"') and rewritten to be faster; 1404: - appel_gnuplot() is fixed. When no graphic was available, it returned a 1405: segfault. 1406: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2) 1407: - RPL/2 is compiled by gcc-3.2.2 and seems to work; 1408: - the same minor bug is fixed in REDRAW and DRAX functions; 1409: - a minor fix is written in DRAW function (2D and 3D); 1410: - AXES intrinsic is improved.
