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

76: - some regressions between libtool 1.x and 2.x are fixed by workarouds in
77: Makefiles;
1.15 bertrand 78: - -a command line option analyzes program (structure and syntax) and
79: sends preprocessor output to standard output. This option is used by
80: rplc (RPL/2 compiler).
1.13 bertrand 81: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
82: - in formatted file, string format returned a variable length string even if
83: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
1.15 bertrand 84: a variable length string and 'CHARACTER*(n)' a fixed length string;
1.13 bertrand 85: - keyed access files support is added. Currently, only formatted files are
86: supported;
87: - direct access files support is added. Currenlty, these files can only be used
88: in formatted mode;
89: - virtual variables are now writte in UTF-8 and all special characters
90: in string are escaped;
1.12 bertrand 91: - all formatted files are now converted into UTF-8;

1.12 bertrand 93: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
94: each execution (md5 and sha1 sums) to enhance security. If one of these tools
95: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
96: on a non recoverable system error;
97: - openssl and sqlite3 libraries are added;
98: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
99: variable indicates RPL/2 root directory. If it is not set, root path
100: is given by configure script (d_exec_path);
1.11 bertrand 101: * Thu Mar 03 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.11 (RPL/2)
102: - configure.in and makefile.am's are modified to add Cygwin support. Interix

115: avoid a minor bug in EDIT and VISIT intrinsics;
1.4 bertrand 116: - minor bug is fixed in formateur_reel();
1.7 bertrand 117: - file-5.03 is patched to avoid bus error on systems that require memory
1.3 bertrand 118: alignment;
1.2 bertrand 119: - minor bug is fixed in evaluation(). Error returned by RPL/C external functions
120: were able to be avoided by evaluation routine.

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

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

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

318: is send from an external process;
319: - configure.in is modified to avoid a libc bug on Solaris (free() can enter in
320: deadlock when a huge amount of threads is launched);
321: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
322: arguments types are unsupported;
323: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All

330: allocations. This function has a positive impact on execution speed;
331: - PSHPRFL and PULPRFL have been added;
332: - RPL/2 can be built on Solaris 64 bits with some minor scripts alterations.
333: See README for more explanations;
334: - MTXSTATUS intrinsic is added;
335: - YIELD intrinsic is added;
336: - ERRM is fixed. In some cases, ERRM uses some uninitialized pointers;
337: - SHARED and PRIVATE intrinsics have been added. A shared variable is a
338: static variable that is shared by multiple threads;
339: - '->' intrinsic is improved. All object copies have been avoided;
340: - -n flag is added to catch HUP signal. stderr and stdout are redirected
341: to a file, stdin is redirected to /dev/null when control process is killed;
342: - a mutex is added to each object (before this modification,
343: RPL/2 used a global mutex and performances in multithreaded programs were very
344: poor.);
345: - ALARM is now interruptible;
346: - both PUT and PUTI intrinsics are improved and do not copy list and table
347: when nombre_occurrences == 1;

354: - profile statistics have been added. See -P option;
355: - major bug is fixed in analyse_syntaxique();
356: - new SQL type is added;
357: - due to a trouble in libpq in multithreaded context, SQL intrinsic is split
358: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
359: that all programs that worked with old SQL intrinsic can now work with
360: SQLQUERY. With all new programs, you can open a real connection to databases;
361: - NRPROC is added. This new intrinsic is used to catch error from child
362: process. Without NRPROC, any errors returned by child process cause
363: main process to abort;
364: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
365: starts a new process). There are no mutexes in RPL/2 because all spawned process
366: use specific context. Nevertheless, shared variables and associated mutexes
367: should be added;
368: - -D flag and DAEMONIZE intrinsic have been added;
369: - REPEAT, THEN, ELSE and ELSEIF intrinsics are rewritten to be more efficient;
370: - autoconf script is modified to handle mysql and postgresql on non standard

384: it's done. Data integrity is now respected during transmission (POKE, SEND and
385: SWI);
386: - ITRACE is added. This intrinsic is only used to debug internal structures and
387: should not be used in regular programs;
388: - SWISTATUS is written;
389: - WFACK is written;

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

1153: occurs when a syntax error is detected;
1154: - #error and #warning preprocessor macros are added;
1155: - INCR and DECR are written (with integer or variable argument);
1156: - CSWP and RSWP are added and tested;
1157: - a minor bug is fixed in analyse.c;
1158: - DEBIAN/control is added to build debian package;

1161: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1162: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1163: VISIT does not find a name in level 1;
1164: - configure.in script is modified to add a new test (--enable-debug
1165: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1166: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1167: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1168: 'MATRIX' { 2 2 3 } GETR;
1169: - LOGSCALE intrinsic is improved and now, it can be used as
1170: { "main" "auxiliary" X Y } LOGSCALE;
1171: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1172: same than AXES:
1173: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1174: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1175: { { -10 10 } "automatic" } SCALE.
1176: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1177: because it changes only the dimension of the screen. To have a logarithmic
1178: scale, you must use LOGSCALE intrinsic:
1179: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1180: screen on second scale;
1181: - { X X } autoscale and { Y Y } logscale are now invalid;
1182: - *D is added (depth multiplication, for 3D graphics);
1183: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1184: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1185: - a major bug is fixed in GETI instrinsic when it is used with a name
1186: that contains a matrix or a vector (bad upper bounds conditions in
1187: incrementation);
1188: - DISP intrinsic now uses the 33-th flag. When it is not set
1189: (default), a final carriage return is sent to the terminal;
1190: - AXES intrinsic only takes a list that can contains the keywork
1191: "main" or "auxiliary". Before this modification, this keyword was in
1192: the first stack level;
1193: - vim syntax file is upgraded;
1194: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1195: option;
1196: - LAST is now disabled in the main loop of INT intrinsic;
1197: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.

1199: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1200: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1201: in 0);
1202: - LAST is disabled in the main loop of DRAW intrinsic;
1203: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1204: evaluation of an equation, the system stack is returned corrupted to the
1205: sequencer;
1206: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1207: of a loop are not integer or real.
1208: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1209: - the compilation stage aborts with an error message when two definitions
1210: have the same name. To improve the compilation() subroutine, I have to
1211: add some tests in gestion_variables.c;
1212: - recherche_type() subroutine ad some other connex subroutines are improved.
1213: Now, some syntax errors about object are caught and do not perform sequencer
1214: hangup;

1216: - Makefile.am's and configure.in scripts are improved.
1217: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1218: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1219: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1236: - a minor bug is fixed in evaluation subroutine;
1237: - vim syntax file is improved;
1238: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1239: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1240: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1241: is a quick and dirty workaround...);
1242: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1243: - rplconvert is improved.
