Now, this function gives same 10: result with ou without -p switch. 11: * Wed Jun 22 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.0.prerelease.2 (RPL/2) 12: - memory caching is added to new variable tree. 13: * Tue Jun 21 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.0.prerelease.1 (RPL/2) 14: - SPAWN is now usable with new variable management; 15: - MEM is rewritten; 16: - PRUSR is rewritten; 17: - merge 4_0 branch into HEAD; 18: - CLUSR is rewritten; 19: - -p flag is now usable; 20: - New benchmark: 21: cauchy:[~/rpl/bench] > ./bench.rpl 22: +++RPL/2 (R) version 4.1.0.prerelease.1 (lundi 20/06/2011, 23:00:45 CEST) 23: +++Copyright (C) 1989 à 2010, 2011 BERTRAND Joël 24: Number of scalar operations per second and per core : 2625369.22710792 25: * Mon Jun 20 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.1.0.prerelease.0 (RPL/2) 26: - New variable management is written. Please note that -p flag does not work 27: and all multithread/multitask capabilities have been disabled until this 28: new subsystem shall be validated. 29: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2) 30: - major bug is fixed in STD format (1E7 sq prints 1); 31: - major bug is fixed in READ intrinsic (socket). This bug was introduced 32: by a new feature in glibc. 33: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2) 34: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and 35: "ALL" IMPLICIT when it runs in interactive mode; 36: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used 37: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have 38: to use SAVE to manipulate global variables; 39: - replace erroneous TAB by TBL in evaluation() and formateur_fichier() 40: subroutines; 41: - fix major memory access violation in evaluation subroutine. Only occurs 42: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds; 43: - fix major bug in evaluation subroutine. 'X(i)' returns execution error 44: when X was a vector or a table. 45: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2) 46: - Gnuplot is upgraded; 47: - flag 34 is now used to enable or disable control character evaluation; 48: - major bug is fixed in P->R intrinsic function when argument type is 49: complex and degree mode is set; 50: - L->T and T->L are added; 51: - OLD filetype is fixed; 52: - FLOW socket support is added; 53: - FLOW sequential files are added; 54: - new escape sequence is added to handle flow files (\x + hexadecimal code). 55: Known escape sequences are \", \b, \n, \t, \x?? and \\. 56: * Sun Mar 06 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2) 57: - Ncurses is upgraded to 5.8; 58: - ALARM is fixed by filling isdst field; 59: - catch ECONNRESET in write intrinsic to return an execution error instead of 60: system one; 61: - fix a typo in HELP intrinsic; 62: - Openssl is upgraded to 1.0.0d, sqlite to 3.7.5 and readline to 6.2; 63: - Lapack is upgraded to 3.3.0; 64: - libmtmalloc is now default Solaris allocator; 65: - ncurses is upgraded; 66: - regression introduced by 4.0.19 is fixed in signal management. 67: Interruption1() could be called from itself and raises bus error (on sparc) or 68: segmentation fault; 69: - sqlite is upgraded to 3.7.4; 70: - OpenSSL is upgraded to 1.0.0c; 71: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore); 72: - characters are tested in recherche_type() to avoid names like '12+'; 73: - gnuplot is upgraded to 4.4.2 due to major bugs. 74: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2) 75: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed. 76: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap 77: corruption.

This function is disabled or forced on 102: systems that does not provide correct POSIX or SysV semaphores subsystem; 103: - a dirty but not quick patch is written to workaround broken siginfo 104: structures. This patch has been successfully tested. It uses a segment of 105: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process 106: (Unix PID); 107: - some OpenBSD's hacks are added; 108: - broken siginfo->si_pid field is now checked by configure script; 109: - SWI now sends SIGCONT to interrupted process to start interrupt without delay; 110: - random generator is cloned by SPAWN; 111: - in transliteration subroutine : '\r' is added after all '\n' in OS/2 port; 112: - getaddrinfo is hardcoded when host system does not provide getaddrinfo 113: or freeaddrinfo; 114: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable; 115: - major bug is fixed in CHR intrinsic when obtained character is not printable; 116: - Lapack is upgraded to 3.2.2; 117: - OS/2 (eComStation 2.0 with EMX 0.9d) support is added; 118: - TOKENIZE is now able to convert escape sequences; 119: - ATPOKE and CLRATPOKE new intrinsics are added; 120: - --enable-full-static configure flag is added.

When a global 129: variable was created and when a local variable existed with the same name, 130: computed address of global variable was wrong; 131: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3 132: is forced in front of all libraries. 133: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2) 134: - BACKTRACE intrinsic is added; 135: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs 136: when this structure is included in IFERR/THEN/END structure and when an error is 137: caught; 138: - major bug is fixed in analyse() subroutine. When evaluation() returned error 139: in a compiled program, analyse() caught this error twice and randomly aborted 140: with a segmentation error; 141: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces; 142: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop 143: signals; 144: - memory leak is fixed in ROW+.

SQL connections were closed in all chield 170: process; 171: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs 172: discovered in Solaris thread safe allocators (libmalloc and libumem) that 173: are first fit class allocators. Solaris libmtmalloc works better and is 174: a best fit class allocator but its performance is poor than ptmalloc3 175: performance; 176: - major bug is fixed in ROW+ intrinsic (new row was not added where it 177: should); 178: - minor bugs are fixed in interruptions.c (semaphores values when error is 179: caught); 180: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process 181: created by SPAWN; 182: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute 183: ATEXIT. If it receives SIGFABORT, it does not; 184: - ONEXIT is renamed in ATEXIT; 185: - ONEXIT new intrinsic is added. 186: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2) 187: - major bug is fixed in static and shared variables initialization subroutine. 188: This bug only occurs when RPL/2 tries to create a shared or static variable 189: from an expression; 190: - major bug is fixed in copie_etat_processus(). A field that contains 191: information about shared variable was not copied to new processus structure; 192: - some little memory leaks are fixed in evaluation(), recherche_type() and 193: sequenceur(). They only occured when syntax error were caught; 194: - IMPLICIT causes execution error instead system error; 195: - Hurd support is improved but currently broken because Hurd does not support 196: SIG_INFO. Work in progress; 197: - OpenBSD specific support is removed from sources; 198: - support for Mac OS X and Windows/Cygwin is added. 199: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2) 200: - implicit names can now be disabled by new IMPLICIT intrinsic: 201: cauchy:[~/cvs/test] > cat implicit.rpl 202: #!/usr/local/bin/rpl -sp 203: TEST 204: << 205: "none" implicit 206: 207: 1 -> Z 208: << 209: Z disp 210: 'Z' disp 211: >> 212: 213: 'Z' disp 214: Z disp // Undefined 215: >> 216: 217: cauchy:[~/cvs/test] > LANG=C ./implicit.rpl 218: +++RPL/2 (R) version 4.0.13 (Wednesday 04/07/10, 13:57:44 CEST) 219: +++Copyright (C) 1989 to 2009, 2010 BERTRAND Joel 220: 1 221: 'Z' 222: 'Z' 223: +++System : Invalid implicit name [6631] 224: cauchy:[~/cvs/test] > 225: 226: RPL/2 aborts because the last Z is undefined and not protected by ''. 227: By default, implicit is set to "ALL"; 228: - sqlite is upgraded to 3.6.23.1; 229: - openssl is upgraded to 1.0.0; 230: - major bug is fixed in RETURN intrinsic.

When a program was daemonized, all 293: signals sent to main process were not caught because DAEMON did not replace 294: old pid by new one; 295: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression 296: evaluation when an error is reported from a subroutine in another subroutine. 297: For example, error was not caught in following program when it is executed with 298: -p option : 299: TEST << iferr TEST2 then end >> 300: TEST2 << 0 inv >> 301: - major bug is fixed in variable management. Some local variables were 302: seen as global ones; 303: - major bug is fixed in rplcore. Rplcore entered in dead lock when 304: script file contains a multibyte character; 305: - IN intrinsic is added; 306: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME 307: returned false ; 308: - major bug is fixed in RETURN intrinsic. It only occurs in compiled 309: programs; 310: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments; 311: - regression is fixed in compilation().

Communication 346: between process are done with pipes and these pipes are managed by a 347: specific asynchrone thread. If a script try to create more threads than 348: management thread can destroy, you can quickly achieve maximum number of 349: opened files and pipe() shall return a system error. This macro tries to create 350: pipes. If pipe() function returns an error, macro waits and retries. If 351: number of retries is greater than a hardcoded value, macro returns an error; 352: - major bug (deadlock) is fixed in process and thread management. I hope 353: this bug shall be the last one; 354: - major bug is fixed in DET intrinsic (determinant was computed without LU 355: diagonalization); 356: - SWAPCNTXT is added; 357: - minor bug is fixed in Makefile.am (licences rule). 358: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2) 359: - some bugfixes are added in process management; 360: - all process management is rewritten to avoid usage of defunct process 361: or thread number; 362: - new major bug is fixed in interruptions.c.

Warning: [[]] SIZE 1297: returns { 1 0 } and it is not a bug, because a null matrix contains _one_ 1298: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 }; 1299: - EXTERNAL intrinsic is added. Warning: by default, extern functions are 1300: disabled. Arguments of EXTERNAL are case sensitive because the external 1301: interface is written in C. { ext_sinus } EXTERNAL does not replace the list 1302: of known external functions but add the new list to the last. { "all" } 1303: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all 1304: external names of the known functions; 1305: - mkrplso.in is modified. 1306: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2) 1307: - vim syntax file is upgraded; 1308: - a minor mistake is fixed in recherche_instruction_suivante(); 1309: - some minor memory leaks are fixed in recherche_type() function.

It only occurs when 1320: VISIT does not find a name in level 1; 1321: - configure.in script is modified to add a new test (--enable-debug 1322: flag). Configured with this fleg, RPL/2 will be built with electric-fences; 1323: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions 1324: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or 1325: 'MATRIX' { 2 2 3 } GETR; 1326: - LOGSCALE intrinsic is improved and now, it can be used as 1327: { "main" "auxiliary" X Y } LOGSCALE; 1328: - SCALE intrinsic is used to fix the limits of a graphic.

To have a logarithmic 1335: scale, you must use LOGSCALE intrinsic: 1336: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log 1337: screen on second scale; 1338: - { X X } autoscale and { Y Y } logscale are now invalid; 1339: - *D is added (depth multiplication, for 3D graphics); 1340: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y 1341: and Z axes). The result of *S is the same than DUP DUP *H *W *D; 1342: - a major bug is fixed in GETI instrinsic when it is used with a name 1343: that contains a matrix or a vector (bad upper bounds conditions in 1344: incrementation); 1345: - DISP intrinsic now uses the 33-th flag. When it is not set 1346: (default), a final carriage return is sent to the terminal; 1347: - AXES intrinsic only takes a list that can contains the keywork 1348: "main" or "auxiliary". Before this modification, this keyword was in 1349: the first stack level; 1350: - vim syntax file is upgraded; 1351: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise 1352: option; 1353: - LAST is now disabled in the main loop of INT intrinsic; 1354: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h. 1355: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2) 1356: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW 1357: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X' 1358: in 0); 1359: - LAST is disabled in the main loop of DRAW intrinsic; 1360: - a major bug is fixed in DRAW intrinsic. When an error occurs in the 1361: evaluation of an equation, the system stack is returned corrupted to the 1362: sequencer; 1363: - the same minor bug is fixed in FOR and START. It only occurs when the limits 1364: of a loop are not integer or real. 1365: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2) 1366: - the compilation stage aborts with an error message when two definitions 1367: have the same name. To improve the compilation() subroutine, I have to 1368: add some tests in gestion_variables.c; 1369: - recherche_type() subroutine ad some other connex subroutines are improved. 1370: Now, some syntax errors about object are caught and do not perform sequencer 1371: hangup; 1372: - readline is upgraded (minor compilation bug with recent gcc); 1373: - Makefile.am's and configure.in scripts are improved. 1374: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2) 1375: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D 1376: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown 1377: the boxwidth, 1 by default); 1378: - recherche_type() is rewritten to be faster; 1379: - gsl is upgraded (release 1.3); 1380: - ncurses is upgraded and patched (release 5.3); 1381: - recherche_instruction_suivante() is fixed (string research with included 1382: '"') and rewritten to be faster; 1383: - appel_gnuplot() is fixed. When no graphic was available, it returned a 1384: segfault. 1385: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2) 1386: - RPL/2 is compiled by gcc-3.2.2 and seems to work; 1387: - the same minor bug is fixed in REDRAW and DRAX functions; 1388: - a minor fix is written in DRAW function (2D and 3D); 1389: - AXES intrinsic is improved.
