Annotation of rpl/ChangeLog, revision 1.30
1.30 ! bertrand 1: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
1.29 bertrand 2: - all '-' are replaced by '_' in random generator list;
1.28 bertrand 3: - minor memory leak is fixed in OPEN intrinsic (socket);
4: - major bug is fixed in IFERR structure. Only occurs in compiled program;
5: - major bug is fixed in copie_objet() and liberation(). Only concerns
6: format in FCH (file descriptor) and SCK (socket descriptor);
7: - debug routines are improved;
8: - PROCID is added;
9: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
10: and to not use swap;
1.26 bertrand 11: - major bug is fixed in sql support. SQL connections were closed in all chield
12: process;
13: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
14: discovered in Solaris thread safe allocators (libmalloc and libumem) that
15: are first fit class allocators. Solaris libmtmalloc works better and is
16: a best fit class allocator but its performance is poor than ptmalloc3
17: performance;
1.24 bertrand 18: - major bug is fixed in ROW+ intrinsic (new row was not added where it
19: should);
20: - minor bugs are fixed in interruptions.c (semaphores values when error is
21: caught);
22: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
23: created by SPAWN;
24: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
25: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 26: - ONEXIT is renamed in ATEXIT;
27: - ONEXIT new intrinsic is added.
1.20 bertrand 28: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
29: - major bug is fixed in static and shared variables initialization subroutine.
30: This bug only occurs when RPL/2 tries to create a shared or static variable
31: from an expression;
32: - major bug is fixed in copie_etat_processus(). A field that contains
33: information about shared variable was not copied to new processus structure;
1.19 bertrand 34: - some little memory leaks are fixed in evaluation(), recherche_type() and
35: sequenceur(). They only occured when syntax error were caught;
36: - IMPLICIT causes execution error instead system error;
37: - Hurd support is improved but currently broken because Hurd does not support
38: SIG_INFO. Work in progress;
39: - OpenBSD specific support is removed from sources;
40: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 41: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)
42: - implicit names can now be disabled by new IMPLICIT intrinsic:

69: By default, implicit is set to "ALL";
1.16 bertrand 70: - sqlite is upgraded to 3.6.23.1;
71: - openssl is upgraded to 1.0.0;
72: - major bug is fixed in RETURN intrinsic. It only occurs in evaluation
73: subroutine;
74: - table variable can now be sorted by SORT;
75: - some regressions between libtool 1.x and 2.x are fixed by workarouds in
76: Makefiles;
1.15 bertrand 77: - -a command line option analyzes program (structure and syntax) and
78: sends preprocessor output to standard output. This option is used by
79: rplc (RPL/2 compiler).
1.13 bertrand 80: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
81: - in formatted file, string format returned a variable length string even if
82: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 83: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 84: - keyed access files support is added. Currently, only formatted files are
85: supported;
86: - direct access files support is added. Currenlty, these files can only be used
87: in formatted mode;
88: - virtual variables are now writte in UTF-8 and all special characters
89: in string are escaped;
1.12 bertrand 90: - all formatted files are now converted into UTF-8;
1.17 bertrand 91: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
1.12 bertrand 92: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
93: each execution (md5 and sha1 sums) to enhance security. If one of these tools
94: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
95: on a non recoverable system error;
96: - openssl and sqlite3 libraries are added;
97: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
98: variable indicates RPL/2 root directory. If it is not set, root path
99: is given by configure script (d_exec_path);
1.11 bertrand 100: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
101: - configure.in and makefile.am's are modified to add Cygwin support. Interix

104: - TeX files are now written in UTF-8 even default locale differs;
105: - minor bug is fixed in ->STR (escaped characters);
1.9 bertrand 106: - minor bug is fixed in ->Q intrinsic. Resultat is returned as integer
107: fraction intead real one;
108: - SIGN now returns (0,0) instead (nan,nan) when complex argument is null;
1.8 bertrand 109: - Makefile.am are modified to authorize parallel builds;
1.7 bertrand 110: - minor bug is fixed in CR intrinsic. CR sends a carriage return to printer
111: and writes warning to standard output;

114: avoid a minor bug in EDIT and VISIT intrinsics;
1.4 bertrand 115: - minor bug is fixed in formateur_reel();
1.7 bertrand 116: - file-5.03 is patched to avoid bus error on systems that require memory
1.3 bertrand 117: alignment;
1.2 bertrand 118: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
119: were able to be avoided by evaluation routine.
1.1 bertrand 120: * Tue Jan 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.9 (RPL/2)

125: Number of scalar operations per second and per core : 2383016
126:
127: - PULPRFL does not abort on BUG() but on execution error;
128: - TRIM, REPL and TOKENIZE are added;
129: - sockets options are now set before bind();
130: - shutdown() is added to all connected sockets;
131: - minor bug is fixed in SUB intrinsic (segfault when SUB is called with
132: list argument and inexistant elements).
133: * Fri Jan 08 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.8 (RPL/2)
134: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
135: signals sent to main process were not caught because DAEMON did not replace
136: old pid by new one;
137: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
138: evaluation when an error is reported from a subroutine in another subroutine.
139: For example, error was not caught in following program when it is executed with
140: -p option :
141: TEST << iferr TEST2 then end >>
142: TEST2 << 0 inv >>
143: - major bug is fixed in variable management. Some local variables were
144: seen as global ones;
145: - major bug is fixed in rplcore. Rplcore entered in dead lock when
146: script file contains a multibyte character;
147: - IN intrinsic is added;
148: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
149: returned false ;
150: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
151: programs;
152: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
153: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and
154: strings were never closed;
155: - some bugs have been fixed in file management;
156: - RPL/2 can now be run on EBCDIC systems (OS/390);
157: - major bug is fixed in -A command line option (NULL character is missing);
158: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
159: made by blocks (1024 bytes). When an incomplete multibyte sequence is
160: encountered at end of block, subroutine aborts with an execution error;
161: - major bug is fixed in OPEN (TCP/IPv4 sockets).
162: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
163: - DISP now locks stdout;
164: - rpliconv is added to replace standard iconv provided by operating system.
165: Indeed, conversion between different encodages requires transliteration
166: that is not offered by some iconv utility;
167: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
168: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
169: not be found), SYSEVAL enters in a dead lock;
170: - fprintf is replaced by some functions that allow transliterations between
171: locales;
172: - '"' can now be used in strings ("\"");
173: - iconv is called with -c in preprocessor stage. It is done to write
174: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
175: - double free is fixed in liberation() (type SQL, only occurs when locale is
176: set);
177: - LOCALIZATION, UCASE and LCASE are added;
178: - major bug is fixed in EXIT intrinsic that was able to return a false
179: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
180: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
181: used in onLoading from shared library, USE was pushed on stack as algebraic
182: expression;
183: - libiconv is upgraded to 1.13.1;
184: - gnuplot is upgraded to 4.2.6;
185: - gsl is upgraded to 1.13.
186: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
187: - pipe() is overwritten by a macro to avoid a system error. Communication
188: between process are done with pipes and these pipes are managed by a
189: specific asynchrone thread. If a script try to create more threads than
190: management thread can destroy, you can quickly achieve maximum number of
191: opened files and pipe() shall return a system error. This macro tries to create
192: pipes. If pipe() function returns an error, macro waits and retries. If
193: number of retries is greater than a hardcoded value, macro returns an error;
194: - major bug (deadlock) is fixed in process and thread management. I hope
195: this bug shall be the last one;
196: - major bug is fixed in DET intrinsic (determinant was computed without LU
197: diagonalization);
198: - SWAPCNTXT is added;
199: - minor bug is fixed in Makefile.am (licences rule).
200: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
201: - some bugfixes are added in process management;
202: - all process management is rewritten to avoid usage of defunct process
203: or thread number;
204: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
205: was called before a pending interruption5 (SIGFSTOP), signal handler uses
206: a freed semaphore and corrupts heap;
207: - CLRERR is added to erase previous errors;
208: - ERRN and ERRM return exception message and number;
209: - major bug is fixed in interruptions.c. All signal are now bufferised
210: when semaphore_liste_threads is null to avoid deadlock. This bug only
211: occured when STOP was sent to a dying thread or process (when this thread or
212: process was running retrait_thread());
213: - matrix rank is computed before matrix inversion;
214: - file locks are added to stdin and stdout. stderr is not locked because
215: all messages written by signal handlers are sent to stderr;
216: - configure.in script is modified to test gcc version and avoid a bug in
217: gcc older than 4.4;
218: - some benchmarks have been done :

237: - DIAG-> and ->DIAG are added;
238: - major bug is fixed in DET intrinsic. DET is rewritten to avoid usage of
239: eigenvalues. In a first time, matrix rank is estimated to force determinant
240: to zero if matrix is rank deficient. If not, a PLU decomposition is done to
241: compute determinant;
242: - QR matrix decomposition is added;
243: - LQ matrix decomposition is added;
244: - Fortran90 files are rewritten to use Fortran2003 bind(C) statement and

247: -Wno-unused-parameter;
248: - all mathematical exceptions are now signaled by exceptions instead of
249: execution error;
250: - minor bug is fixed in both CSTOP and RSTOP intrinsics. Without this fix, you
251: can call twice CSTOP without RSTOP;
252: - named semaphore support is added (CRSMPHR, CLRSMPHR, SMHRDECR, SMPHRINCR,
253: SMPHRTRYDECR, SMPHGETV).
254: * Fri Jul 24 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.4 (RPL/2)
255: - semaphore is added in interruptions.c to avoid segmentation fault when STOP
256: signal is sent to a dying thread. Some mutexes are replaced by semaphores too
257: to be used in signal handlers;
258: - major bug (memory corruption) is fixed in COL- intrinsic;
259: - minor bug is fixed in ALARM and WAIT. These temporisations stopped when a
260: software interrupt was caught;
261: - rplpp man page is added.
262: * Fri Jul 17 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.3 (RPL/2)
263: - minor bug is fixed in WRITE (SIGPIPE is ignored to catch error without
264: process termination);
265: - major bug is fixed in FUSE intrinsic (FUSE kills itself and do not kill
266: its parent);
267: - a mutex to protect fork() syscall is added;
268: - all mutexes are unlocked after fork() in DETACH;
269: - minor bug (double free corruption) is fixed in CLOSE intrinsic;
270: - major bug is fixed in lecture_pipe when a nullified list is sent into a pipe;
271: - WORKDIR intrinsic is added;
272: - Level 0 variables are shared between all threads without copy. Indeed,
273: there variables are not modifiable and only contains static user definitions;
274: - branches prediction is added in THEN, ELSE, ELSEIF and REPEAT intrinsics;
275: - FORTRAN 77 file management subroutines are rewritten in pure C due to
276: FORTRAN string management. C/FORTRAN 77 string interfaces are broken
277: in some cases (gcc/gfortran/libc/OS and arch conjonction);
278: - a memory leak is fixed in REMOVE intrinsic;
279: - major bug is fixed in MySQL driver (segfault due to a bug in mysql_init()
280: and due to a libmysqlclient that is not thread safe).
281: * Wen Jun 10 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.2 (RPL/2)
282: - new enhanced allocator is written for regular variables, static variables and
283: shared variables;
284: - major bug is fixed in src/interruptions.c. This file did not compile
285: when SQL support was not enabled;
286: - new allocator is written for system stack and last stack;
287: - --enable-profile flag is added to configure script. When this flag is
288: enabled, rpl is built with -pg option;
289: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
290: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
291: process is killed;
292: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
293: know typeof() intrinsic function. This function is not standard but exists
294: under Sun Studio, gcc, and maybe some others compilers. If this function does
295: not exist on your compiler, you can change its definition by old one in
296: src/rpl.h;
297: - fflush() can now be interrupted by signal (SunOS);
298: - fflush(NULL) is called before all fork() occurrences;
299: - generators returned by RDGN help are sorted;

314: - readline is upgraded to 6.0;
315: - file is upgraded to 5.0;
316: - Signal handlers are rewritten to send signal to main thread when a signal
317: is send from an external process;
318: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
319: deadlock when a huge amount of threads is launched);
320: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
321: arguments types are unsupported;
322: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
323: data are buffered. PLOT is used to draw these objects.);
324: - MARK instrinsic is added;

326: - some regression bugs have been fixed, some memory leaks too.
327: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)
328: - an estimation of future stack elements is added to avoid some costly memory
329: allocations. This function has a positive impact on execution speed;
330: - PSHPRFL and PULPRFL have been added;
331: - RPL/2 can be built on Solaris 64 bits with some minor scripts alterations.
332: See README for more explanations;
333: - MTXSTATUS intrinsic is added;
334: - YIELD intrinsic is added;
335: - ERRM is fixed. In some cases, ERRM uses some uninitialized pointers;
336: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
337: static variable that is shared by multiple threads;
338: - '->' intrinsic is improved. All object copies have been avoided;
339: - -n flag is added to catch HUP signal. stderr and stdout are redirected
340: to a file, stdin is redirected to /dev/null when control process is killed;
341: - a mutex is added to each object (before this modification,
342: RPL/2 used a global mutex and performances in multithreaded programs were very
343: poor.);
344: - ALARM is now interruptible;
345: - both PUT and PUTI intrinsics are improved and do not copy list and table
346: when nombre_occurrences == 1;
347: - COPY intrinsic is added. Argument (that can be pointed from some objects)
348: is replaced by a new copy of itself;
349: - memory leak is fixed in sequenceur(). It only occurs when an execution error
350: is caught from interactive mode;
351: - mutexes have been added (CRMTX, CLRMTX, MTXLOCK, MTXUNLOCK);
352: - new mutex type is added;
353: - profile statistics have been added. See -P option;
354: - major bug is fixed in analyse_syntaxique();
355: - new SQL type is added;
356: - due to a trouble in libpq in multithreaded context, SQL intrinsic is split
357: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
358: that all programs that worked with old SQL intrinsic can now work with
359: SQLQUERY. With all new programs, you can open a real connection to databases;
360: - NRPROC is added. This new intrinsic is used to catch error from child
361: process. Without NRPROC, any errors returned by child process cause
362: main process to abort;
363: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
364: starts a new process). There are no mutexes in RPL/2 because all spawned process
365: use specific context. Nevertheless, shared variables and associated mutexes
366: should be added;
367: - -D flag and DAEMONIZE intrinsic have been added;
368: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;
369: - autoconf script is modified to handle mysql and postgresql on non standard
370: directories;
371: - -t flag is fixed ('\0' is missing...);
372: - SWI and SEND pipes have been modified to be more robust on systems where
373: getpid() can return (pid_t) -1 or (pid_t) -2 value;
374: - major bug is fixed in REPEAT intrinsic. Only occurs in compiled mode;
375: - all but jump variables are removed from source. All signal handlers now
376: use encapsulated variables and signals are caught by thread;

378: - NEWPLANE is added;
379: - LINE is added;
380: - DGTIZ is added;
381: - major bug is fixed in ROW-> intrinsic (comes from new garbage collector);

383: it's done. Data integrity is now respected during transmission (POKE, SEND and
384: SWI);
385: - ITRACE is added. This intrinsic is only used to debug internal structures and
386: should not be used in regular programs;
387: - SWISTATUS is written;
388: - WFACK is written;
389: - rplcore files are now able to handle compilation errors;
390: - rplcore files are now able to handle evaluation and interruption errors;
391: - SORT can now be used on table;

716: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
717: versions of PROTECT and UNPROTECT that only deal with global variables
718: (see RCL/SAVE);
719: - variable management routines have been rewritten. The new ones are
720: uncompatible with the old ones. Before these changes, a local variable
721: was exported to a child subroutine, but cannot be modified into this
722: child subroutine. Now, a local variable is accessible only in its subroutine;
723: - SAVE intrinsic is added to manipulate global variables;

1153: - #error and #warning preprocessor macros are added;
1154: - INCR and DECR are written (with integer or variable argument);
1155: - CSWP and RSWP are added and tested;
1156: - a minor bug is fixed in analyse.c;
1157: - DEBIAN/control is added to build debian package;

1160: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1161: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1162: VISIT does not find a name in level 1;
1163: - configure.in script is modified to add a new test (--enable-debug
1164: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1165: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1166: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1167: 'MATRIX' { 2 2 3 } GETR;
1168: - LOGSCALE intrinsic is improved and now, it can be used as
1169: { "main" "auxiliary" X Y } LOGSCALE;
1170: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1171: same than AXES:
1172: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1173: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1174: { { -10 10 } "automatic" } SCALE.
1175: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1176: because it changes only the dimension of the screen. To have a logarithmic
1177: scale, you must use LOGSCALE intrinsic:
1178: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1179: screen on second scale;
1180: - { X X } autoscale and { Y Y } logscale are now invalid;
1181: - *D is added (depth multiplication, for 3D graphics);
1182: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1183: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1184: - a major bug is fixed in GETI instrinsic when it is used with a name
1185: that contains a matrix or a vector (bad upper bounds conditions in
1186: incrementation);
1187: - DISP intrinsic now uses the 33-th flag. When it is not set
1188: (default), a final carriage return is sent to the terminal;
1189: - AXES intrinsic only takes a list that can contains the keywork
1190: "main" or "auxiliary". Before this modification, this keyword was in
1191: the first stack level;
1192: - vim syntax file is upgraded;
1193: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1194: option;
1195: - LAST is now disabled in the main loop of INT intrinsic;
1196: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.

1198: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1199: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1200: in 0);
1201: - LAST is disabled in the main loop of DRAW intrinsic;
1202: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1203: evaluation of an equation, the system stack is returned corrupted to the
1204: sequencer;
1205: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1206: of a loop are not integer or real.
1207: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1208: - the compilation stage aborts with an error message when two definitions
1209: have the same name. To improve the compilation() subroutine, I have to
1210: add some tests in gestion_variables.c;
1211: - recherche_type() subroutine ad some other connex subroutines are improved.
1212: Now, some syntax errors about object are caught and do not perform sequencer
1213: hangup;

1215: - Makefile.am's and configure.in scripts are improved.
1216: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1217: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1218: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1219: the boxwidth, 1 by default);
1220: - recherche_type() is rewritten to be faster;
1221: - gsl is upgraded (release 1.3);
1222: - ncurses is upgraded and patched (release 5.3);

1235: - a minor bug is fixed in evaluation subroutine;
1236: - vim syntax file is improved;
1237: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1238: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1239: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1240: is a quick and dirty workaround...);
1241: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1242: - rplconvert is improved.
