1: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
2: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan
3: and renamed;
4: - some workarounds have been written to not use buggy klibc SystemV IPCS.
5: ABORT now works on eComStation;
6: - sqlite is upgraded to 3.7.2;
7: - bug is fixed in software interrupts. When both process have different PID,
8: parent process was not interrupted if it is not group master process. To fix
9: this bug, SIGINJECT signal is not sent by child process but by control thread
10: in parent process;
11: - minor bug is fixed in data injection (POKE) that does not work as expected
12: when child process is protected by NRPROC.
13: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
14: - --enable-sysv-sems is added to configure script to use SystemV semaphores
15: functions instead of POSIX functions. This function is disabled or forced on
16: systems that does not provide correct POSIX or SysV semaphores subsystem;
17: - a dirty but not quick patch is written to workaround broken siginfo
18: structures. This patch has been successfully tested. It uses a segment of
19: shared memory (SysV) and eleven semaphores (Posix or SysV) by process
20: (Unix PID);
21: - some OpenBSD's hacks are added;
22: - broken siginfo->si_pid field is now checked by configure script;
23: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
24: - random generator is cloned by SPAWN;

37: - sqlite is upgraded to 3.7.0.1;
38: - units is upgraded to 1.88;
39: - another major bug is fixed in the same variable creation subroutine.
40: Level 0 and 1 variables adresses were swapped when a global variable masked
41: a name of RPL/2 routine;
42: - major bug is fixed in global variable creation subroutine. When a global
43: variable was created and when a local variable existed with the same name,
44: computed address of global variable was wrong;
45: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
46: is forced in front of all libraries.
47: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
48: - BACKTRACE intrinsic is added;

50: when this structure is included in IFERR/THEN/END structure and when an error is
51: caught;
52: - major bug is fixed in analyse() subroutine. When evaluation() returned error
53: in a compiled program, analyse() caught this error twice and randomly aborted
54: with a segmentation error;
55: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
56: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
57: signals;

80: - PROCID is added;
81: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
82: and to not use swap;
83: - major bug is fixed in sql support. SQL connections were closed in all chield
84: process;
85: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
86: discovered in Solaris thread safe allocators (libmalloc and libumem) that
87: are first fit class allocators. Solaris libmtmalloc works better and is
88: a best fit class allocator but its performance is poor than ptmalloc3
89: performance;
90: - major bug is fixed in ROW+ intrinsic (new row was not added where it
91: should);
92: - minor bugs are fixed in interruptions.c (semaphores values when error is

105: information about shared variable was not copied to new processus structure;
106: - some little memory leaks are fixed in evaluation(), recherche_type() and
107: sequenceur(). They only occured when syntax error were caught;
108: - IMPLICIT causes execution error instead system error;
109: - Hurd support is improved but currently broken because Hurd does not support
110: SIG_INFO. Work in progress;
111: - OpenBSD specific support is removed from sources;
112: - support for Mac OS X and Windows/Cygwin is added.
113: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

152: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
153: - in formatted file, string format returned a variable length string even if
154: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
155: a variable length string and 'CHARACTER*(n)' a fixed length string;
156: - keyed access files support is added. Currently, only formatted files are
157: supported;
158: - direct access files support is added. Currenlty, these files can only be used
159: in formatted mode;
160: - virtual variables are now writte in UTF-8 and all special characters
161: in string are escaped;
162: - all formatted files are now converted into UTF-8;

164: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
165: each execution (md5 and sha1 sums) to enhance security. If one of these tools
166: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
167: on a non recoverable system error;
168: - openssl and sqlite3 libraries are added;
169: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
170: variable indicates RPL/2 root directory. If it is not set, root path
171: is given by configure script (d_exec_path);
172: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

206: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
207: signals sent to main process were not caught because DAEMON did not replace
208: old pid by new one;
209: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
210: evaluation when an error is reported from a subroutine in another subroutine.
211: For example, error was not caught in following program when it is executed with
212: -p option :
213: TEST << iferr TEST2 then end >>
214: TEST2 << 0 inv >>
215: - major bug is fixed in variable management. Some local variables were
216: seen as global ones;
217: - major bug is fixed in rplcore. Rplcore entered in dead lock when
218: script file contains a multibyte character;
219: - IN intrinsic is added;
220: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
221: returned false ;
222: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
223: programs;
224: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
225: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
226: strings were never closed;

232: encountered at end of block, subroutine aborts with an execution error;
233: - major bug is fixed in OPEN (TCP/IPv4 sockets).
234: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
235: - DISP now locks stdout;
236: - rpliconv is added to replace standard iconv provided by operating system.
237: Indeed, conversion between different encodages requires transliteration
238: that is not offered by some iconv utility;
239: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
240: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

256: - gnuplot is upgraded to 4.2.6;
257: - gsl is upgraded to 1.13.

259: - pipe() is overwritten by a macro to avoid a system error. Communication
260: between process are done with pipes and these pipes are managed by a
261: specific asynchrone thread. If a script try to create more threads than
262: management thread can destroy, you can quickly achieve maximum number of
263: opened files and pipe() shall return a system error. This macro tries to create
264: pipes. If pipe() function returns an error, macro waits and retries. If
265: number of retries is greater than a hardcoded value, macro returns an error;
266: - major bug (deadlock) is fixed in process and thread management. I hope
267: this bug shall be the last one;
268: - major bug is fixed in DET intrinsic (determinant was computed without LU

274: - all process management is rewritten to avoid usage of defunct process
275: or thread number;
276: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
277: was called before a pending interruption5 (SIGFSTOP), signal handler uses
278: a freed semaphore and corrupts heap;
279: - CLRERR is added to erase previous errors;
280: - ERRN and ERRM return exception message and number;
281: - major bug is fixed in interruptions.c. All signal are now bufferised
282: when semaphore_liste_threads is null to avoid deadlock. This bug only
283: occured when STOP was sent to a dying thread or process (when this thread or
284: process was running retrait_thread());
285: - matrix rank is computed before matrix inversion;
286: - file locks are added to stdin and stdout. stderr is not locked because
287: all messages written by signal handlers are sent to stderr;

399: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)
400: - an estimation of future stack elements is added to avoid some costly memory
401: allocations. This function has a positive impact on execution speed;
402: - PSHPRFL and PULPRFL have been added;
403: - RPL/2 can be built on Solaris 64 bits with some minor scripts alterations.
404: See README for more explanations;
405: - MTXSTATUS intrinsic is added;
406: - YIELD intrinsic is added;
407: - ERRM is fixed. In some cases, ERRM uses some uninitialized pointers;
408: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
409: static variable that is shared by multiple threads;
410: - '->' intrinsic is improved. All object copies have been avoided;
411: - -n flag is added to catch HUP signal. stderr and stdout are redirected
412: to a file, stdin is redirected to /dev/null when control process is killed;
413: - a mutex is added to each object (before this modification,
414: RPL/2 used a global mutex and performances in multithreaded programs were very
415: poor.);
416: - ALARM is now interruptible;
417: - both PUT and PUTI intrinsics are improved and do not copy list and table
418: when nombre_occurrences == 1;
419: - COPY intrinsic is added. Argument (that can be pointed from some objects)
420: is replaced by a new copy of itself;
421: - memory leak is fixed in sequenceur(). It only occurs when an execution error

430: that all programs that worked with old SQL intrinsic can now work with
431: SQLQUERY. With all new programs, you can open a real connection to databases;
432: - NRPROC is added. This new intrinsic is used to catch error from child
433: process. Without NRPROC, any errors returned by child process cause
434: main process to abort;
435: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
436: starts a new process). There are no mutexes in RPL/2 because all spawned process
437: use specific context. Nevertheless, shared variables and associated mutexes
438: should be added;
439: - -D flag and DAEMONIZE intrinsic have been added;
440: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;

455: it's done. Data integrity is now respected during transmission (POKE, SEND and
456: SWI);
457: - ITRACE is added. This intrinsic is only used to debug internal structures and
458: should not be used in regular programs;
459: - SWISTATUS is written;

526: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
527: workaround for this major bug. Nevertheless, all others capabilities seems to
528: work fine;
529: - '->' is modified to return error when program tries to initialiaze two
530: variables with the same name like

578: - -f parameter is added when iconv is called;
579: - as old file program was bugged, a new option is added to configure script.
580: When configure is called with --disable-encoding-autodetection, make does not
581: try to detect source encoding. Please, do not use if RPL/2 can be built
582: without this option !
583: - new garbage collector (and more efficient) is written;
584: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
585: not support real time signals, RPL/2 cannot use multitasking functions;
586: - error returned by preprocessor are now catched by RPL/2;
587: - -p option is added. With this option, all scripts are compiled before
588: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
589: 40% faster;
590: - read and write operations in pipe() are rewritten to be sure that such
591: operations are atomic;
592: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

717: - MEM does not report static variable sizes;
718: - minor bug is fixed in HELP intrinsic. When the last instruction was not
719: known, HELP function was pushed in operational stack. HELP did not work

733: - external wrapper (rplplot) is written to force usage of gnuplot provided
734: by RPL/2 if it is built during build process. If this build does not exist,
735: it tries to launch regular gnuplot;
736: - gnuplot is added to source tree to avoid some trouble between preinstalled
737: gnuplot and release used by RPL/2. This addition to source tree is
738: required by some incompatibility between gnuplot releases;
739: - Lapack is upgraded to 3.1.1 release;
740: - GSL is upgraded to 1.9 revision;
741: - RPL_TMP_PATH env variable is added to specify the path of tempfiles. If

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

774: >>
775:
776: VAR_S2
777: <<
778: static 3 -> C << C disp 'C' decr >>
779: >>
780:
781: - configure.in script is added in lapack subtree;
782: - VARS is modified to display variables status (LOCKED/UNLOCKED and
783: STATIC/VOLATILE/PARAMETER/VARIABLE);
784: - STATIC and VOLATILE intrinsics are added to specify static variables. A
785: static variable can be transformed into volatile with VOLATILE.
786: With STATIC, next variables created by '->' are static;
787: - PROTECT and UNPROTECT are added to protect variables against write
788: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
789: versions of PROTECT and UNPROTECT that only deal with global variables
790: (see RCL/SAVE);
791: - variable management routines have been rewritten. The new ones are
792: uncompatible with the old ones. Before these changes, a local variable
793: was exported to a child subroutine, but cannot be modified into this

1172: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1173: - SLICESCALE intrinsic is added. Its syntax is
1174: { "automatic" nb_of_levels }
1175: { "discrete" l1 l2 l3 ... }
1176: { "incremental" start incr }
1177: { "incremental" start incr end }
1178: { "automatic" } (default);
1179: - a minor bug (in last stack) is fixed in AXES intrinsic
1180: - flag 52 is used to automatically update graphics;
1181: - man pages are updated;
1182: - evaluation() is modified to perform evaluation of expressions that contain
1183: '=';
1184: - a minor bug is fixed in AXES intrinsic;
1185: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1186: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1187: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1188: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1189: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1200: structure. ELSE is modified to return an error when ELSE appears in
1201: an ELSE/END structure;
1202: - a major bug is fixed in CYCLE;

1205: - SCLS is added;
1206: - DRWS now uses COLS to draw 2D graphics;
1207: - PPAR and SPAR are written. SPAR returns a list that contains the
1208: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1209: statistical variable, or "DISABLED" if its type is not one of the type of
1210: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1211: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1212: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1213: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1214: disabled. Arguments of EXTERNAL are case sensitive because the external
1215: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1216: of known external functions but add the new list to the last. { "all" }
1217: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1218: external names of the known functions;
1219: - mkrplso.in is modified.
1220: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1221: - vim syntax file is upgraded;
1222: - a minor mistake is fixed in recherche_instruction_suivante();
1223: - some minor memory leaks are fixed in recherche_type() function. They only
1224: occurs when a syntax error is detected;

1231: - PUTC and PUTR new intrinsics are added.
1232: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1233: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1234: VISIT does not find a name in level 1;
1235: - configure.in script is modified to add a new test (--enable-debug
1236: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1237: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1238: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1239: 'MATRIX' { 2 2 3 } GETR;
1240: - LOGSCALE intrinsic is improved and now, it can be used as
1241: { "main" "auxiliary" X Y } LOGSCALE;
1242: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1243: same than AXES:
1244: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1245: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1246: { { -10 10 } "automatic" } SCALE.
1247: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1248: because it changes only the dimension of the screen. To have a logarithmic
1249: scale, you must use LOGSCALE intrinsic:
1250: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1251: screen on second scale;
1252: - { X X } autoscale and { Y Y } logscale are now invalid;
1253: - *D is added (depth multiplication, for 3D graphics);
1254: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1255: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1256: - a major bug is fixed in GETI instrinsic when it is used with a name
1257: that contains a matrix or a vector (bad upper bounds conditions in
1258: incrementation);
1259: - DISP intrinsic now uses the 33-th flag. When it is not set
1260: (default), a final carriage return is sent to the terminal;
1261: - AXES intrinsic only takes a list that can contains the keywork
1262: "main" or "auxiliary". Before this modification, this keyword was in
1263: the first stack level;
1264: - vim syntax file is upgraded;
1265: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1266: option;
1267: - LAST is now disabled in the main loop of INT intrinsic;
1268: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1269: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1270: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1271: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1272: in 0);
1273: - LAST is disabled in the main loop of DRAW intrinsic;
1274: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1275: evaluation of an equation, the system stack is returned corrupted to the
1276: sequencer;
1277: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1278: of a loop are not integer or real.
1279: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1281: have the same name. To improve the compilation() subroutine, I have to
1282: add some tests in gestion_variables.c;
1283: - recherche_type() subroutine ad some other connex subroutines are improved.
1284: Now, some syntax errors about object are caught and do not perform sequencer
1285: hangup;

1287: - Makefile.am's and configure.in scripts are improved.
1288: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1289: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1290: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1310: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1311: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1312: is a quick and dirty workaround...);
1313: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1314: - rplconvert is improved.
