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

20: when this structure is included in IFERR/THEN/END structure and when an error is
21: caught;
22: - major bug is fixed in analyse() subroutine. When evaluation() returned error
23: in a compiled program, analyse() caught this error twice and randomly aborted
24: with a segmentation error;
25: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
26: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
27: signals;

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

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

123: - in formatted file, string format returned a variable length string even if
124: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
125: a variable length string and 'CHARACTER*(n)' a fixed length string;
126: - keyed access files support is added. Currently, only formatted files are
127: supported;
128: - direct access files support is added. Currenlty, these files can only be used
129: in formatted mode;
130: - virtual variables are now writte in UTF-8 and all special characters

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

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

188: script file contains a multibyte character;
189: - IN intrinsic is added;
190: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
191: returned false ;

213: locales;
214: - '"' can now be used in strings ("\"");
215: - iconv is called with -c in preprocessor stage. It is done to write

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

248: a freed semaphore and corrupts heap;
249: - CLRERR is added to erase previous errors;
250: - ERRN and ERRM return exception message and number;
251: - major bug is fixed in interruptions.c. All signal are now bufferised

253: occured when STOP was sent to a dying thread or process (when this thread or
254: process was running retrait_thread());
255: - matrix rank is computed before matrix inversion;

400: that all programs that worked with old SQL intrinsic can now work with
401: SQLQUERY. With all new programs, you can open a real connection to databases;
402: - NRPROC is added. This new intrinsic is used to catch error from child
403: process. Without NRPROC, any errors returned by child process cause
404: main process to abort;
405: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
406: starts a new process). There are no mutexes in RPL/2 because all spawned process
407: use specific context. Nevertheless, shared variables and associated mutexes
408: should be added;

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

548: - -f parameter is added when iconv is called;
549: - as old file program was bugged, a new option is added to configure script.
550: When configure is called with --disable-encoding-autodetection, make does not
551: try to detect source encoding. Please, do not use if RPL/2 can be built
552: without this option !
553: - new garbage collector (and more efficient) is written;

557: - -p option is added. With this option, all scripts are compiled before
558: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
559: 40% faster;
560: - read and write operations in pipe() are rewritten to be sure that such
561: operations are atomic;
562: - minor bug is fixed in LOGSCALE. With {} LOGSCALE, all scales have to be

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

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

1163: - static archive is modified to include all required libraries needed by
1164: RPL/2.
1165: * Sun May 4 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6i (RPL/2)
1166: - '=' is added and tested;
1167: - XCOL and YCOL are added;
1168: - a minor bug in analyse_syntaxique() is fixed;
1169: - THEN is modified to return an error when ELSE appears in a CASE/THEN/END
1170: structure. ELSE is modified to return an error when ELSE appears in
1171: an ELSE/END structure;
1172: - a major bug is fixed in CYCLE;
1173: - EXIT is written. When EXIT appears in a defined loop (FOR or START), the
1174: sequencer continues after the end of this loop;
1175: - SCLS is added;
1176: - DRWS now uses COLS to draw 2D graphics;
1177: - PPAR and SPAR are written. SPAR returns a list that contains the
1178: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1179: statistical variable, or "DISABLED" if its type is not one of the type of
1180: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1181: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1182: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1183: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1184: disabled. Arguments of EXTERNAL are case sensitive because the external
1185: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1186: of known external functions but add the new list to the last. { "all" }
1187: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1188: external names of the known functions;
1189: - mkrplso.in is modified.
1190: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1191: - vim syntax file is upgraded;
1192: - a minor mistake is fixed in recherche_instruction_suivante();
1193: - some minor memory leaks are fixed in recherche_type() function. They only
1194: occurs when a syntax error is detected;
1195: - #error and #warning preprocessor macros are added;
1196: - INCR and DECR are written (with integer or variable argument);
1197: - CSWP and RSWP are added and tested;
1198: - a minor bug is fixed in analyse.c;
1199: - DEBIAN/control is added to build debian package;
1200: - SCALE is fixed and improved ("automatic" keyword);
1201: - PUTC and PUTR new intrinsics are added.
1202: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1203: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1204: VISIT does not find a name in level 1;
1205: - configure.in script is modified to add a new test (--enable-debug
1206: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1207: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1208: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1209: 'MATRIX' { 2 2 3 } GETR;
1210: - LOGSCALE intrinsic is improved and now, it can be used as
1211: { "main" "auxiliary" X Y } LOGSCALE;
1212: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1213: same than AXES:
1214: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1215: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1216: { { -10 10 } "automatic" } SCALE.
1217: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1218: because it changes only the dimension of the screen. To have a logarithmic
1219: scale, you must use LOGSCALE intrinsic:
1220: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1221: screen on second scale;
1222: - { X X } autoscale and { Y Y } logscale are now invalid;
1223: - *D is added (depth multiplication, for 3D graphics);
1224: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1225: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1226: - a major bug is fixed in GETI instrinsic when it is used with a name
1227: that contains a matrix or a vector (bad upper bounds conditions in
1228: incrementation);
1229: - DISP intrinsic now uses the 33-th flag. When it is not set
1230: (default), a final carriage return is sent to the terminal;
1231: - AXES intrinsic only takes a list that can contains the keywork
1232: "main" or "auxiliary". Before this modification, this keyword was in
1233: the first stack level;
1234: - vim syntax file is upgraded;
1235: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1236: option;
1237: - LAST is now disabled in the main loop of INT intrinsic;
1238: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1239: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1240: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1241: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1242: in 0);
1243: - LAST is disabled in the main loop of DRAW intrinsic;
1244: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1245: evaluation of an equation, the system stack is returned corrupted to the
1246: sequencer;
1247: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1248: of a loop are not integer or real.
1249: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1250: - the compilation stage aborts with an error message when two definitions
1251: have the same name. To improve the compilation() subroutine, I have to
1252: add some tests in gestion_variables.c;
1253: - recherche_type() subroutine ad some other connex subroutines are improved.
1254: Now, some syntax errors about object are caught and do not perform sequencer
1255: hangup;
1256: - readline is upgraded (minor compilation bug with recent gcc);
1257: - Makefile.am's and configure.in scripts are improved.
1258: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1259: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1260: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1261: the boxwidth, 1 by default);
1262: - recherche_type() is rewritten to be faster;
1263: - gsl is upgraded (release 1.3);
1264: - ncurses is upgraded and patched (release 5.3);
1265: - recherche_instruction_suivante() is fixed (string research with included
1266: '"') and rewritten to be faster;
1267: - appel_gnuplot() is fixed. When no graphic was available, it returned a
1268: segfault.
1269: * Sun Mar 9 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6c (RPL/2)

1277: - a minor bug is fixed in evaluation subroutine;
1278: - vim syntax file is improved;
1279: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1280: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1281: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1282: is a quick and dirty workaround...);
1283: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1284: - rplconvert is improved.
1285: * Sun Dec 22 2002 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6a (RPL/2)
