17: a name of RPL/2 routine;
18: - major bug is fixed in global variable creation subroutine. When a global
19: variable was created and when a local variable existed with the same name,
20: computed address of global variable was wrong;
21: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
22: is forced in front of all libraries.

60: process;
61: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
62: discovered in Solaris thread safe allocators (libmalloc and libumem) that
63: are first fit class allocators. Solaris libmtmalloc works better and is

83: sequenceur(). They only occured when syntax error were caught;
84: - IMPLICIT causes execution error instead system error;
85: - Hurd support is improved but currently broken because Hurd does not support
86: SIG_INFO. Work in progress;
87: - OpenBSD specific support is removed from sources;
88: - support for Mac OS X and Windows/Cygwin is added.
89: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

129: - in formatted file, string format returned a variable length string even if
130: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
131: a variable length string and 'CHARACTER*(n)' a fixed length string;
132: - keyed access files support is added. Currently, only formatted files are
133: supported;
134: - direct access files support is added. Currenlty, these files can only be used
135: in formatted mode;
136: - virtual variables are now writte in UTF-8 and all special characters
137: in string are escaped;

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

182: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
183: signals sent to main process were not caught because DAEMON did not replace
184: old pid by new one;
185: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
186: evaluation when an error is reported from a subroutine in another subroutine.
187: For example, error was not caught in following program when it is executed with

189: TEST << iferr TEST2 then end >>
190: TEST2 << 0 inv >>
191: - major bug is fixed in variable management. Some local variables were
192: seen as global ones;

194: script file contains a multibyte character;
195: - IN intrinsic is added;
196: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
197: returned false ;

209: - major bug is fixed in OPEN (TCP/IPv4 sockets).
210: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
211: - DISP now locks stdout;
212: - rpliconv is added to replace standard iconv provided by operating system.
213: Indeed, conversion between different encodages requires transliteration
214: that is not offered by some iconv utility;
215: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
216: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

218: - fprintf is replaced by some functions that allow transliterations between
219: locales;
220: - '"' can now be used in strings ("\"");
221: - iconv is called with -c in preprocessor stage. It is done to write

235: - pipe() is overwritten by a macro to avoid a system error. Communication
236: between process are done with pipes and these pipes are managed by a
237: specific asynchrone thread. If a script try to create more threads than
238: management thread can destroy, you can quickly achieve maximum number of
239: opened files and pipe() shall return a system error. This macro tries to create
240: pipes. If pipe() function returns an error, macro waits and retries. If
241: number of retries is greater than a hardcoded value, macro returns an error;
242: - major bug (deadlock) is fixed in process and thread management. I hope
243: this bug shall be the last one;

254: a freed semaphore and corrupts heap;
255: - CLRERR is added to erase previous errors;
256: - ERRN and ERRM return exception message and number;
257: - major bug is fixed in interruptions.c. All signal are now bufferised
258: when semaphore_liste_threads is null to avoid deadlock. This bug only
259: occured when STOP was sent to a dying thread or process (when this thread or
260: process was running retrait_thread());
261: - matrix rank is computed before matrix inversion;
262: - file locks are added to stdin and stdout. stderr is not locked because
263: all messages written by signal handlers are sent to stderr;

407: SQLQUERY. With all new programs, you can open a real connection to databases;
408: - NRPROC is added. This new intrinsic is used to catch error from child
409: process. Without NRPROC, any errors returned by child process cause
410: main process to abort;
411: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
412: starts a new process). There are no mutexes in RPL/2 because all spawned process

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

709: - external wrapper (rplplot) is written to force usage of gnuplot provided
710: by RPL/2 if it is built during build process. If this build does not exist,
711: it tries to launch regular gnuplot;
712: - gnuplot is added to source tree to avoid some trouble between preinstalled
713: gnuplot and release used by RPL/2. This addition to source tree is
714: required by some incompatibility between gnuplot releases;
715: - Lapack is upgraded to 3.1.1 release;
716: - GSL is upgraded to 1.9 revision;

761: static variable can be transformed into volatile with VOLATILE.
762: With STATIC, next variables created by '->' are static;
763: - PROTECT and UNPROTECT are added to protect variables against write
764: or purge actions. New PARAMETER and VARIABLE intrinsics are modified
765: versions of PROTECT and UNPROTECT that only deal with global variables
766: (see RCL/SAVE);
767: - variable management routines have been rewritten. The new ones are
768: uncompatible with the old ones. Before these changes, a local variable
769: was exported to a child subroutine, but cannot be modified into this
770: child subroutine. Now, a local variable is accessible only in its subroutine;
771: - SAVE intrinsic is added to manipulate global variables;
772: - SUSPEND is written. RPL/2 waits for a SIGCONT signal;
773: - SORT, COL->, ->COL, ROW->, ROW-> intrinsics are written;

785: operating system);
786: - minor bug fixed in SCLS (mistake between main and auxiliary axes);
787: - variables are now written in rpl-core file;
788: - NEG is modified to return 0 instead -0 when its argument is real or complex
789: number;
790: - ROW+ intrinsic can now be used on empty matrix without dimension error:

1164: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)
1165: - SLICE intrinsic is added. It is used to draw 3D graphics as contour lines;
1166: - PLOTTER is added to draw statistical clouds with lines;
1167: - C and H source files now include vim parameters;
1168: - vim syntax file is modified to include new intrinsics;
1169: - static archive is modified to include all required libraries needed by
1170: RPL/2.
1171: * Sun May 4 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6i (RPL/2)
1172: - '=' is added and tested;
1173: - XCOL and YCOL are added;
1174: - a minor bug in analyse_syntaxique() is fixed;
1175: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1176: structure. ELSE is modified to return an error when ELSE appears in
1177: an ELSE/END structure;
1178: - a major bug is fixed in CYCLE;
1179: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1180: sequencer continues after the end of this loop;
1181: - SCLS is added;
1182: - DRWS now uses COLS to draw 2D graphics;
1183: - PPAR and SPAR are written. SPAR returns a list that contains the
1184: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1185: statistical variable, or "DISABLED" if its type is not one of the type of
1186: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1187: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1188: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1189: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1190: disabled. Arguments of EXTERNAL are case sensitive because the external
1191: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1192: of known external functions but add the new list to the last. { "all" }
1193: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1194: external names of the known functions;
1195: - mkrplso.in is modified.
1196: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1197: - vim syntax file is upgraded;
1198: - a minor mistake is fixed in recherche_instruction_suivante();
1199: - some minor memory leaks are fixed in recherche_type() function. They only
1200: occurs when a syntax error is detected;
1201: - #error and #warning preprocessor macros are added;
1202: - INCR and DECR are written (with integer or variable argument);
1203: - CSWP and RSWP are added and tested;
1204: - a minor bug is fixed in analyse.c;
1205: - DEBIAN/control is added to build debian package;
1206: - SCALE is fixed and improved ("automatic" keyword);
1207: - PUTC and PUTR new intrinsics are added.
1208: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1209: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1210: VISIT does not find a name in level 1;
1211: - configure.in script is modified to add a new test (--enable-debug
1212: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1213: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1214: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1215: 'MATRIX' { 2 2 3 } GETR;
1216: - LOGSCALE intrinsic is improved and now, it can be used as
1217: { "main" "auxiliary" X Y } LOGSCALE;
1218: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1219: same than AXES:
1220: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1221: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1222: { { -10 10 } "automatic" } SCALE.
1223: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1224: because it changes only the dimension of the screen. To have a logarithmic
1225: scale, you must use LOGSCALE intrinsic:
1226: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1227: screen on second scale;
1228: - { X X } autoscale and { Y Y } logscale are now invalid;
1229: - *D is added (depth multiplication, for 3D graphics);
1230: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1231: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1232: - a major bug is fixed in GETI instrinsic when it is used with a name
1233: that contains a matrix or a vector (bad upper bounds conditions in
1234: incrementation);
1235: - DISP intrinsic now uses the 33-th flag. When it is not set
1236: (default), a final carriage return is sent to the terminal;
1237: - AXES intrinsic only takes a list that can contains the keywork
1238: "main" or "auxiliary". Before this modification, this keyword was in
1239: the first stack level;
1240: - vim syntax file is upgraded;
1241: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1242: option;
1243: - LAST is now disabled in the main loop of INT intrinsic;
1244: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1245: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1246: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1247: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1248: in 0);
1249: - LAST is disabled in the main loop of DRAW intrinsic;
1250: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1251: evaluation of an equation, the system stack is returned corrupted to the
1252: sequencer;
1253: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1254: of a loop are not integer or real.
1255: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1256: - the compilation stage aborts with an error message when two definitions
1257: have the same name. To improve the compilation() subroutine, I have to
1258: add some tests in gestion_variables.c;

1263: - Makefile.am's and configure.in scripts are improved.
1264: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1265: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1266: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1267: the boxwidth, 1 by default);
1268: - recherche_type() is rewritten to be faster;
1269: - gsl is upgraded (release 1.3);
1270: - ncurses is upgraded and patched (release 5.3);
1271: - recherche_instruction_suivante() is fixed (string research with included
1272: '"') and rewritten to be faster;

1283: - a minor bug is fixed in evaluation subroutine;
1284: - vim syntax file is improved;
1285: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1286: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1287: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1288: is a quick and dirty workaround...);
1289: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1290: - rplconvert is improved.
