1: * Thu Dec 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.20 (RPL/2)
2: - regression introduced bt 4.0.19 is fixed in signal management.
3: Interruption1() can be called from itself and raises bus error (on sparc) or
4: segmentation fault;
5: - sqlite is upgraded to 3.7.4;
6: - OpenSSL is upgraded to 1.0.0c;
7: - syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);
8: - characters are tested in recherche_type() to avoid names like '12+';
9: - sqlite is upgraded to 3.7.3;
10: - gnuplot is upgraded to 4.4.2 due to major bugs.
11: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
12: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
13: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
14: corruption. As internal memory management have been improved, a best fit
15: allocator like ptmalloc3 is not required anymore;
16: - gnuplot is upgraded to 4.4.1;
17: - deadlock is fixed in signal handlers: same mutex was used in standard
18: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
19: and signal handlers. A new signal handler specific mutex is added;
20: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
21: that has to be evaluated by ->NUM;
22: - rplfile build process is modify to be sure that rplfile is not modified
23: after rpl build stage (to be sure that rplfile checksum is not modified after
24: rpl compilation);
25: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
26: modified to remove yacc code and renamed;
27: - some workarounds have been written to not use buggy klibc SystemV IPCS.
28: ABORT now works on eComStation;
29: - sqlite is upgraded to 3.7.2;
30: - bug is fixed in software interrupts. When both process have different PID,
31: parent process was not interrupted if it is not group master process. To fix
32: this bug, SIGINJECT signal is not sent by child process but by control thread
33: in parent process;
34: - minor bug is fixed in data injection (POKE) that does not work as expected
35: when child process is protected by NRPROC.
36: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
37: - --enable-sysv-sems is added to configure script to use SystemV semaphores
38: functions instead of POSIX functions. This function is disabled or forced on
39: systems that does not provide correct POSIX or SysV semaphores subsystem;
40: - a dirty but not quick patch is written to workaround broken siginfo
41: structures. This patch has been successfully tested. It uses a segment of
42: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
43: (Unix PID);
44: - some OpenBSD's hacks are added;
45: - broken siginfo->si_pid field is now checked by configure script;
46: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;
47: - random generator is cloned by SPAWN;

55: - TOKENIZE is now able to convert escape sequences;
56: - ATPOKE and CLRATPOKE new intrinsics are added;
57: - --enable-full-static configure flag is added. With this flag, mysql and
58: postgresql libraries are statically linked in rpl executable;
59: - units Makefile is modified to avoid readline and ncurses usages;
60: - sqlite is upgraded to 3.7.0.1;
61: - units is upgraded to 1.88;
62: - another major bug is fixed in the same variable creation subroutine.
63: Level 0 and 1 variables adresses were swapped when a global variable masked
64: a name of RPL/2 routine;
65: - major bug is fixed in global variable creation subroutine. When a global
66: variable was created and when a local variable existed with the same name,
67: computed address of global variable was wrong;
68: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
69: is forced in front of all libraries.
70: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
71: - BACKTRACE intrinsic is added;
72: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
73: when this structure is included in IFERR/THEN/END structure and when an error is
74: caught;
75: - major bug is fixed in analyse() subroutine. When evaluation() returned error
76: in a compiled program, analyse() caught this error twice and randomly aborted
77: with a segmentation error;
78: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
79: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
80: signals;
81: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
82: matrix.
83: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)

103: - PROCID is added;
104: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
105: and to not use swap;
106: - major bug is fixed in sql support. SQL connections were closed in all chield
107: process;
108: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
109: discovered in Solaris thread safe allocators (libmalloc and libumem) that
110: are first fit class allocators. Solaris libmtmalloc works better and is
111: a best fit class allocator but its performance is poor than ptmalloc3
112: performance;
113: - major bug is fixed in ROW+ intrinsic (new row was not added where it
114: should);
115: - minor bugs are fixed in interruptions.c (semaphores values when error is
116: caught);
117: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
118: created by SPAWN;
119: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
120: ATEXIT. If it receives SIGFABORT, it does not;
121: - ONEXIT is renamed in ATEXIT;

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

175: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
176: - in formatted file, string format returned a variable length string even if
177: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
178: a variable length string and 'CHARACTER*(n)' a fixed length string;
179: - keyed access files support is added. Currently, only formatted files are
180: supported;
181: - direct access files support is added. Currenlty, these files can only be used
182: in formatted mode;
183: - virtual variables are now writte in UTF-8 and all special characters
184: in string are escaped;
185: - all formatted files are now converted into UTF-8;
186: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
187: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
188: each execution (md5 and sha1 sums) to enhance security. If one of these tools
189: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
190: on a non recoverable system error;
191: - openssl and sqlite3 libraries are added;
192: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
193: variable indicates RPL/2 root directory. If it is not set, root path
194: is given by configure script (d_exec_path);
195: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)

229: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
230: signals sent to main process were not caught because DAEMON did not replace
231: old pid by new one;
232: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
233: evaluation when an error is reported from a subroutine in another subroutine.
234: For example, error was not caught in following program when it is executed with
235: -p option :
236: TEST << iferr TEST2 then end >>
237: TEST2 << 0 inv >>
238: - major bug is fixed in variable management. Some local variables were
239: seen as global ones;
240: - major bug is fixed in rplcore. Rplcore entered in dead lock when
241: script file contains a multibyte character;
242: - IN intrinsic is added;
243: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
244: returned false ;
245: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
246: programs;
247: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
248: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

252: - major bug is fixed in -A command line option (NULL character is missing);
253: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
254: made by blocks (1024 bytes). When an incomplete multibyte sequence is
255: encountered at end of block, subroutine aborts with an execution error;
256: - major bug is fixed in OPEN (TCP/IPv4 sockets).
257: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
258: - DISP now locks stdout;
259: - rpliconv is added to replace standard iconv provided by operating system.
260: Indeed, conversion between different encodages requires transliteration
261: that is not offered by some iconv utility;
262: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
263: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

282: - pipe() is overwritten by a macro to avoid a system error. Communication
283: between process are done with pipes and these pipes are managed by a
284: specific asynchrone thread. If a script try to create more threads than
285: management thread can destroy, you can quickly achieve maximum number of
286: opened files and pipe() shall return a system error. This macro tries to create
287: pipes. If pipe() function returns an error, macro waits and retries. If
288: number of retries is greater than a hardcoded value, macro returns an error;
289: - major bug (deadlock) is fixed in process and thread management. I hope
290: this bug shall be the last one;
291: - major bug is fixed in DET intrinsic (determinant was computed without LU

301: a freed semaphore and corrupts heap;
302: - CLRERR is added to erase previous errors;
303: - ERRN and ERRM return exception message and number;
304: - major bug is fixed in interruptions.c. All signal are now bufferised
305: when semaphore_liste_threads is null to avoid deadlock. This bug only
306: occured when STOP was sent to a dying thread or process (when this thread or
307: process was running retrait_thread());
308: - matrix rank is computed before matrix inversion;
309: - file locks are added to stdin and stdout. stderr is not locked because
310: all messages written by signal handlers are sent to stderr;

454: SQLQUERY. With all new programs, you can open a real connection to databases;
455: - NRPROC is added. This new intrinsic is used to catch error from child
456: process. Without NRPROC, any errors returned by child process cause
457: main process to abort;
458: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
459: starts a new process). There are no mutexes in RPL/2 because all spawned process
460: use specific context. Nevertheless, shared variables and associated mutexes
461: should be added;

756: - external wrapper (rplplot) is written to force usage of gnuplot provided
757: by RPL/2 if it is built during build process. If this build does not exist,
758: it tries to launch regular gnuplot;
759: - gnuplot is added to source tree to avoid some trouble between preinstalled
760: gnuplot and release used by RPL/2. This addition to source tree is
761: required by some incompatibility between gnuplot releases;

787: #!/usr/local/bin/rpl -sc
788:
789: TEST
790: <<
791: 1 1000 start VAR_S VAR_S2 next
792: >>
793:
794: VAR_S
795: <<
796: static 3 -> C << C disp 'C' incr if C 10 > then 'C' volatile end >>

1184: 2: integer (number of column to be inserted)
1185: 1: column matrix to be inserted;
1186: - major bug was discovered in interface_gnuplot(). It only occurs when

1195: * Sun Jun 1 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6k (RPL/2)
1196: - SLICESCALE intrinsic is added. Its syntax is
1197: { "automatic" nb_of_levels }
1198: { "discrete" l1 l2 l3 ... }
1199: { "incremental" start incr }
1200: { "incremental" start incr end }
1201: { "automatic" } (default);

1203: - flag 52 is used to automatically update graphics;
1204: - man pages are updated;
1205: - evaluation() is modified to perform evaluation of expressions that contain
1206: '=';
1207: - a minor bug is fixed in AXES intrinsic;
1208: - a minor bug is fixed in DRAW intrinsic (2D and 3D graphics were able to
1209: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1210: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1211: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1212: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;

1228: - SCLS is added;
1229: - DRWS now uses COLS to draw 2D graphics;
1230: - PPAR and SPAR are written. SPAR returns a list that contains the
1231: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1232: statistical variable, or "DISABLED" if its type is not one of the type of
1233: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1234: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1235: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1236: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1237: disabled. Arguments of EXTERNAL are case sensitive because the external
1238: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1239: of known external functions but add the new list to the last. { "all" }
1240: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1241: external names of the known functions;
1242: - mkrplso.in is modified.
1243: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1244: - vim syntax file is upgraded;
1245: - a minor mistake is fixed in recherche_instruction_suivante();
1246: - some minor memory leaks are fixed in recherche_type() function. They only

1254: - PUTC and PUTR new intrinsics are added.
1255: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1256: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1257: VISIT does not find a name in level 1;
1258: - configure.in script is modified to add a new test (--enable-debug
1259: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1260: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1261: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1262: 'MATRIX' { 2 2 3 } GETR;
1263: - LOGSCALE intrinsic is improved and now, it can be used as
1264: { "main" "auxiliary" X Y } LOGSCALE;
1265: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1266: same than AXES:
1267: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1268: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1269: { { -10 10 } "automatic" } SCALE.
1270: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1271: because it changes only the dimension of the screen. To have a logarithmic
1272: scale, you must use LOGSCALE intrinsic:
1273: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1274: screen on second scale;
1275: - { X X } autoscale and { Y Y } logscale are now invalid;
1276: - *D is added (depth multiplication, for 3D graphics);
1277: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1278: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1279: - a major bug is fixed in GETI instrinsic when it is used with a name
1280: that contains a matrix or a vector (bad upper bounds conditions in
1281: incrementation);
1282: - DISP intrinsic now uses the 33-th flag. When it is not set
1283: (default), a final carriage return is sent to the terminal;
1284: - AXES intrinsic only takes a list that can contains the keywork
1285: "main" or "auxiliary". Before this modification, this keyword was in
1286: the first stack level;
1287: - vim syntax file is upgraded;
1288: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1289: option;
1290: - LAST is now disabled in the main loop of INT intrinsic;
1291: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1292: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1293: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1294: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1295: in 0);
1296: - LAST is disabled in the main loop of DRAW intrinsic;
1297: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1298: evaluation of an equation, the system stack is returned corrupted to the
1299: sequencer;
1300: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1301: of a loop are not integer or real.
1302: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1303: - the compilation stage aborts with an error message when two definitions

1310: - Makefile.am's and configure.in scripts are improved.
1311: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1312: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1313: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1314: the boxwidth, 1 by default);
1315: - recherche_type() is rewritten to be faster;
1316: - gsl is upgraded (release 1.3);
1317: - ncurses is upgraded and patched (release 5.3);
1318: - recherche_instruction_suivante() is fixed (string research with included
1319: '"') and rewritten to be faster;

1330: - a minor bug is fixed in evaluation subroutine;
1331: - vim syntax file is improved;
1332: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1333: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1334: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1335: is a quick and dirty workaround...);
1336: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1337: - rplconvert is improved.
1338: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)

1445: - Makefile is improved to support sparc v7 (sun4c), sparc v8 (sun4m) and
1446: sparc v9 (sun4u). Now, RPL/2 can be built on i386 (i486 is known as i386),
1447: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1448: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1449: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1450:
1451: Newton:[~/rpl/rpl] > time make install
1452: ...
1453: real 338m39.623s
1454: user 324m32.290s
