23: new subsystem shall be validated.
24: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
25: - major bug is fixed in STD format (1E7 sq prints 1);
26: - major bug is fixed in READ intrinsic (socket). This bug was introduced
27: by a new feature in glibc.
28: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
29: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
30: "ALL" IMPLICIT when it runs in interactive mode;
31: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
32: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
33: to use SAVE to manipulate global variables;
34: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
35: subroutines;
36: - fix major memory access violation in evaluation subroutine. Only occurs
37: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
38: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
39: when X was a vector or a table.
40: * Sun Apr 04 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.21 (RPL/2)
41: - Gnuplot is upgraded;

68: - gnuplot is upgraded to 4.4.2 due to major bugs.
69: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
70: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
71: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
72: corruption. As internal memory management have been improved, a best fit
73: allocator like ptmalloc3 is not required anymore;
74: - gnuplot is upgraded to 4.4.1;
75: - deadlock is fixed in signal handlers: same mutex was used in standard
76: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
77: and signal handlers. A new signal handler specific mutex is added;
78: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
79: that has to be evaluated by ->NUM;
80: - rplfile build process is modify to be sure that rplfile is not modified
81: after rpl build stage (to be sure that rplfile checksum is not modified after
82: rpl compilation);

86: ABORT now works on eComStation;
87: - sqlite is upgraded to 3.7.2;
88: - bug is fixed in software interrupts. When both process have different PID,
89: parent process was not interrupted if it is not group master process. To fix
90: this bug, SIGINJECT signal is not sent by child process but by control thread
91: in parent process;
92: - minor bug is fixed in data injection (POKE) that does not work as expected
93: when child process is protected by NRPROC.
94: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
95: - --enable-sysv-sems is added to configure script to use SystemV semaphores
96: functions instead of POSIX functions. This function is disabled or forced on
97: systems that does not provide correct POSIX or SysV semaphores subsystem;
98: - a dirty but not quick patch is written to workaround broken siginfo
99: structures. This patch has been successfully tested. It uses a segment of
100: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
101: (Unix PID);
102: - some OpenBSD's hacks are added;
103: - broken siginfo->si_pid field is now checked by configure script;
104: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
105: - random generator is cloned by SPAWN;

113: - TOKENIZE is now able to convert escape sequences;
114: - ATPOKE and CLRATPOKE new intrinsics are added;
115: - --enable-full-static configure flag is added. With this flag, mysql and
116: postgresql libraries are statically linked in rpl executable;
117: - units Makefile is modified to avoid readline and ncurses usages;
118: - sqlite is upgraded to 3.7.0.1;
119: - units is upgraded to 1.88;
120: - another major bug is fixed in the same variable creation subroutine.
121: Level 0 and 1 variables adresses were swapped when a global variable masked
122: a name of RPL/2 routine;
123: - major bug is fixed in global variable creation subroutine. When a global
124: variable was created and when a local variable existed with the same name,
125: computed address of global variable was wrong;
126: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
127: is forced in front of all libraries.
128: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
129: - BACKTRACE intrinsic is added;
130: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
131: when this structure is included in IFERR/THEN/END structure and when an error is
132: caught;
133: - major bug is fixed in analyse() subroutine. When evaluation() returned error
134: in a compiled program, analyse() caught this error twice and randomly aborted
135: with a segmentation error;
136: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
137: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
138: signals;
139: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
140: matrix.
141: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

158: - major bug is fixed in copie_objet() and liberation(). Only concerns
159: format in FCH (file descriptor) and SCK (socket descriptor);
160: - debug routines are improved;
161: - PROCID is added;
162: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
163: and to not use swap;
164: - major bug is fixed in sql support. SQL connections were closed in all chield
165: process;
166: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
167: discovered in Solaris thread safe allocators (libmalloc and libumem) that
168: are first fit class allocators. Solaris libmtmalloc works better and is
169: a best fit class allocator but its performance is poor than ptmalloc3
170: performance;
171: - major bug is fixed in ROW+ intrinsic (new row was not added where it
172: should);
173: - minor bugs are fixed in interruptions.c (semaphores values when error is
174: caught);
175: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
176: created by SPAWN;
177: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
178: ATEXIT. If it receives SIGFABORT, it does not;
179: - ONEXIT is renamed in ATEXIT;
180: - ONEXIT new intrinsic is added.

186: information about shared variable was not copied to new processus structure;
187: - some little memory leaks are fixed in evaluation(), recherche_type() and
188: sequenceur(). They only occured when syntax error were caught;
189: - IMPLICIT causes execution error instead system error;
190: - Hurd support is improved but currently broken because Hurd does not support
191: SIG_INFO. Work in progress;
192: - OpenBSD specific support is removed from sources;
193: - support for Mac OS X and Windows/Cygwin is added.

235: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
236: a variable length string and 'CHARACTER*(n)' a fixed length string;
237: - keyed access files support is added. Currently, only formatted files are
238: supported;
239: - direct access files support is added. Currenlty, these files can only be used
240: in formatted mode;
241: - virtual variables are now writte in UTF-8 and all special characters
242: in string are escaped;
243: - all formatted files are now converted into UTF-8;
244: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
245: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
246: each execution (md5 and sha1 sums) to enhance security. If one of these tools
247: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
248: on a non recoverable system error;
249: - openssl and sqlite3 libraries are added;
250: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
251: variable indicates RPL/2 root directory. If it is not set, root path
252: is given by configure script (d_exec_path);
253: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

286: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
287: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
288: signals sent to main process were not caught because DAEMON did not replace
289: old pid by new one;
290: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
291: evaluation when an error is reported from a subroutine in another subroutine.
292: For example, error was not caught in following program when it is executed with

295: TEST2 << 0 inv >>
296: - major bug is fixed in variable management. Some local variables were

315: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
316: - DISP now locks stdout;
317: - rpliconv is added to replace standard iconv provided by operating system.
318: Indeed, conversion between different encodages requires transliteration
319: that is not offered by some iconv utility;
320: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
321: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

323: - fprintf is replaced by some functions that allow transliterations between
324: locales;
325: - '"' can now be used in strings ("\"");
326: - iconv is called with -c in preprocessor stage. It is done to write
327: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
328: - double free is fixed in liberation() (type SQL, only occurs when locale is
329: set);
330: - LOCALIZATION, UCASE and LCASE are added;

334: used in onLoading from shared library, USE was pushed on stack as algebraic
335: expression;
336: - libiconv is upgraded to 1.13.1;
337: - gnuplot is upgraded to 4.2.6;
338: - gsl is upgraded to 1.13.

340: - pipe() is overwritten by a macro to avoid a system error. Communication
341: between process are done with pipes and these pipes are managed by a
342: specific asynchrone thread. If a script try to create more threads than
343: management thread can destroy, you can quickly achieve maximum number of
344: opened files and pipe() shall return a system error. This macro tries to create
345: pipes. If pipe() function returns an error, macro waits and retries. If
346: number of retries is greater than a hardcoded value, macro returns an error;
347: - major bug (deadlock) is fixed in process and thread management. I hope
348: this bug shall be the last one;
349: - major bug is fixed in DET intrinsic (determinant was computed without LU
350: diagonalization);
351: - SWAPCNTXT is added;

355: - all process management is rewritten to avoid usage of defunct process
356: or thread number;
357: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
358: was called before a pending interruption5 (SIGFSTOP), signal handler uses
359: a freed semaphore and corrupts heap;
360: - CLRERR is added to erase previous errors;
361: - ERRN and ERRM return exception message and number;
362: - major bug is fixed in interruptions.c. All signal are now bufferised
363: when semaphore_liste_threads is null to avoid deadlock. This bug only
364: occured when STOP was sent to a dying thread or process (when this thread or
365: process was running retrait_thread());
366: - matrix rank is computed before matrix inversion;
367: - file locks are added to stdin and stdout. stderr is not locked because
368: all messages written by signal handlers are sent to stderr;
369: - configure.in script is modified to test gcc version and avoid a bug in

443: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
444: process is killed;
445: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
446: know typeof() intrinsic function. This function is not standard but exists
447: under Sun Studio, gcc, and maybe some others compilers. If this function does
448: not exist on your compiler, you can change its definition by old one in
449: src/rpl.h;

511: that all programs that worked with old SQL intrinsic can now work with
512: SQLQUERY. With all new programs, you can open a real connection to databases;
513: - NRPROC is added. This new intrinsic is used to catch error from child
514: process. Without NRPROC, any errors returned by child process cause
515: main process to abort;
516: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
517: starts a new process). There are no mutexes in RPL/2 because all spawned process
518: use specific context. Nevertheless, shared variables and associated mutexes
519: should be added;

660: - as old file program was bugged, a new option is added to configure script.
661: When configure is called with --disable-encoding-autodetection, make does not
662: try to detect source encoding. Please, do not use if RPL/2 can be built
663: without this option !
664: - new garbage collector (and more efficient) is written;

779: - ARCCOS, ARCSIN, ARCTG, ARGCH, ARGSH, ARGTH, CH, SH, TH and TG intrinsics
780: are removed, because all of these intrinsics have two forms. ARCCOS is
781: the same than ACOS, TAN=TG, COSH=CH. Please adapt your scripts;
782: - gnuplot compilation does not have to be done when disable-gnuplot is set;
783: - major bug is fixed in RECV that avoid usage of multitasking.
784: * Tue Jul 10 2007 BERTRAND Joël <rpl@systella.fr> rpl-4.00pre8w (RPL/2)

787: an algebraic expression;
788: - --enable-debug is modified. Now, return can be defined to print
789: on stdout its position in source code (line and function);
790: - minor bug is fixed in recherche_type(). Don't forget that space
791: are not significant in algebraic expression:
792: '12 3+ 12 X' is the same expression than '123+12X';
793: - src/Makefile.am is modified to avoid double compilation process;
794: - --enable-final-run-path is added to configure.in script;

797: ends;
798: - MEM does not report static variable sizes;
799: - minor bug is fixed in HELP intrinsic. When the last instruction was not
800: known, HELP function was pushed in operational stack. HELP did not work

813: - HELP function is rewritten to be more friendly (a la OpenVMS);
814: - external wrapper (rplplot) is written to force usage of gnuplot provided
815: by RPL/2 if it is built during build process. If this build does not exist,
816: it tries to launch regular gnuplot;
817: - gnuplot is added to source tree to avoid some trouble between preinstalled
818: gnuplot and release used by RPL/2. This addition to source tree is
819: required by some incompatibility between gnuplot releases;
820: - Lapack is upgraded to 3.1.1 release;
821: - GSL is upgraded to 1.9 revision;
822: - RPL_TMP_PATH env variable is added to specify the path of tempfiles. If

824: not, ./ but RPL/2 can hang with a fatal error if this last location is
825: not writable;
826: - major regression is fixed in SYSEVAL intrinsic due to introduction of
827: error scrutation.

867: With STATIC, next variables created by '->' are static;
868: - PROTECT and UNPROTECT are added to protect variables against write
869: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
870: versions of PROTECT and UNPROTECT that only deal with global variables
871: (see RCL/SAVE);
872: - variable management routines have been rewritten. The new ones are
873: uncompatible with the old ones. Before these changes, a local variable
874: was exported to a child subroutine, but cannot be modified into this
875: child subroutine. Now, a local variable is accessible only in its subroutine;
876: - SAVE intrinsic is added to manipulate global variables;

1194: (less parenthesis);
1195: - rplpp is modified to workaround a mistake in 'which' function (seems to appear
1196: on Debian distribution, but since cpp is in the default path, RPL/2 works
1197: fine...);
1198: - NOT is not correctly formatted in formateur.c:
1199: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1200: with a NOTZ function !
1201: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)
1202: - CYCLE is fixed. Now, it is possible to use CYCLE in an expression even

1204: - RPL/2 is tested with efence and valgrind;
1205: - configure.in script is modified;
1206: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif
1207: structure. I don't know why this code was compiled by gcc-3.3... Maybe

1286: - SCLS is added;
1287: - DRWS now uses COLS to draw 2D graphics;
1288: - PPAR and SPAR are written. SPAR returns a list that contains the
1289: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1290: statistical variable, or "DISABLED" if its type is not one of the type of
1291: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1292: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1293: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1294: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1295: disabled. Arguments of EXTERNAL are case sensitive because the external
1296: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1297: of known external functions but add the new list to the last. { "all" }
1298: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1299: external names of the known functions;
1300: - mkrplso.in is modified.
1301: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1302: - vim syntax file is upgraded;
1303: - a minor mistake is fixed in recherche_instruction_suivante();

1313: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1314: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1315: VISIT does not find a name in level 1;
1316: - configure.in script is modified to add a new test (--enable-debug
1317: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1318: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1319: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1320: 'MATRIX' { 2 2 3 } GETR;
1321: - LOGSCALE intrinsic is improved and now, it can be used as
1322: { "main" "auxiliary" X Y } LOGSCALE;
1323: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1324: same than AXES:
1325: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1326: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1327: { { -10 10 } "automatic" } SCALE.
1328: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1329: because it changes only the dimension of the screen. To have a logarithmic
1330: scale, you must use LOGSCALE intrinsic:
1331: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1332: screen on second scale;
1333: - { X X } autoscale and { Y Y } logscale are now invalid;
1334: - *D is added (depth multiplication, for 3D graphics);
1335: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1336: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1337: - a major bug is fixed in GETI instrinsic when it is used with a name
1338: that contains a matrix or a vector (bad upper bounds conditions in
1339: incrementation);
1340: - DISP intrinsic now uses the 33-th flag. When it is not set
1341: (default), a final carriage return is sent to the terminal;
1342: - AXES intrinsic only takes a list that can contains the keywork
1343: "main" or "auxiliary". Before this modification, this keyword was in
1344: the first stack level;
1345: - vim syntax file is upgraded;
1346: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1347: option;
1348: - LAST is now disabled in the main loop of INT intrinsic;
1349: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1350: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1351: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1352: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1353: in 0);
1354: - LAST is disabled in the main loop of DRAW intrinsic;
1355: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1356: evaluation of an equation, the system stack is returned corrupted to the
1357: sequencer;
1358: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1359: of a loop are not integer or real.
1360: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1361: - the compilation stage aborts with an error message when two definitions

1363: add some tests in gestion_variables.c;
1364: - recherche_type() subroutine ad some other connex subroutines are improved.
1365: Now, some syntax errors about object are caught and do not perform sequencer
1366: hangup;

1368: - Makefile.am's and configure.in scripts are improved.
1369: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1370: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1371: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1372: the boxwidth, 1 by default);
1373: - recherche_type() is rewritten to be faster;
1374: - gsl is upgraded (release 1.3);
1375: - ncurses is upgraded and patched (release 5.3);
1376: - recherche_instruction_suivante() is fixed (string research with included
1377: '"') and rewritten to be faster;

1391: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1392: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1393: is a quick and dirty workaround...);
1394: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1395: - rplconvert is improved.

1494: that the RPL/2 seqencer must stop and must give a prompt. This
1495: signal is an asynchonous "HALT" command;
1496: - SIGINT (CTRL+C) variables stack corruption is fixed;

1502: * Thu Jan 10 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre3g (RPL/2)
1503: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1504: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1505: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1506: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1507: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1508:
1509: Newton:[~/rpl/rpl] > time make install
1510: ...
1511: real 338m39.623s
1512: user 324m32.290s
1513: sys 10m47.380s
