4: programs;
5: - some memory leaks are fixed in process management (SPAWN and DETACH);
6: - version verification is added to shared objects;
7: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
8: linux (false mremap() prototype);

10: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
11: - all '-' are replaced by '_' in random generator list;
12: - minor memory leak is fixed in OPEN intrinsic (socket);
13: - major bug is fixed in IFERR structure. Only occurs in compiled program;

15: format in FCH (file descriptor) and SCK (socket descriptor);
16: - debug routines are improved;
17: - PROCID is added;
18: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
19: and to not use swap;
20: - major bug is fixed in sql support. SQL connections were closed in all chield
21: process;
22: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
23: discovered in Solaris thread safe allocators (libmalloc and libumem) that
24: are first fit class allocators. Solaris libmtmalloc works better and is
25: a best fit class allocator but its performance is poor than ptmalloc3
26: performance;
27: - major bug is fixed in ROW+ intrinsic (new row was not added where it
28: should);

34: ATEXIT. If it receives SIGFABORT, it does not;
35: - ONEXIT is renamed in ATEXIT;
36: - ONEXIT new intrinsic is added.
37: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)

39: This bug only occurs when RPL/2 tries to create a shared or static variable
40: from an expression;
41: - major bug is fixed in copie_etat_processus(). A field that contains
42: information about shared variable was not copied to new processus structure;
43: - some little memory leaks are fixed in evaluation(), recherche_type() and
44: sequenceur(). They only occured when syntax error were caught;
45: - IMPLICIT causes execution error instead system error;
46: - Hurd support is improved but currently broken because Hurd does not support
47: SIG_INFO. Work in progress;
48: - OpenBSD specific support is removed from sources;
49: - support for Mac OS X and Windows/Cygwin is added.
50: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

89: * Tue Mar 09 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.12 (RPL/2)
90: - in formatted file, string format returned a variable length string even if
91: format was 'CHARACTER*(n)' (n characters string). Now, 'CHARACTER*(*)' returns
92: a variable length string and 'CHARACTER*(n)' a fixed length string;

98: in string are escaped;
99: - all formatted files are now converted into UTF-8;
100: - all file and unix socket names created by RPL/2 are now UTF-8 compliant;
101: - RPL/2 tools (rpliconv, rplfile, rplpp and rplconvert) are now checked before
102: each execution (md5 and sha1 sums) to enhance security. If one of these tools
103: have been modified between RPL/2 compilation and current execution, RPL/2 aborts
104: on a non recoverable system error;
105: - openssl and sqlite3 libraries are added;
106: - RPL_HOME env variable is added. When RPL/2 is called from librpl, this
107: variable indicates RPL/2 root directory. If it is not set, root path
108: is given by configure script (d_exec_path);

143: - minor bug is fixed in DAEMON intrinsic. When a program was daemonized, all
144: signals sent to main process were not caught because DAEMON did not replace
145: old pid by new one;
146: - major bug is fixed in IFERR/THEN/ELSE/END. Only occurs in expression
147: evaluation when an error is reported from a subroutine in another subroutine.
148: For example, error was not caught in following program when it is executed with
149: -p option :

151: TEST2 << 0 inv >>
152: - major bug is fixed in variable management. Some local variables were
153: seen as global ones;

155: script file contains a multibyte character;
156: - IN intrinsic is added;
157: - major bug is fixed in SAME intrinsic : << 1 >> DUP SAME and 'E' DUP SAME
158: returned false ;
159: - major bug is fixed in RETURN intrinsic. It only occurs in compiled
160: programs;
161: - major bug is fixed in NEG intrinsic. NEG did not make a copy of its arguments;
162: - regression is fixed in compilation(). "\\" was analysed as '"' '\' '\"' and

172: - DISP now locks stdout;
173: - rpliconv is added to replace standard iconv provided by operating system.
174: Indeed, conversion between different encodages requires transliteration
175: that is not offered by some iconv utility;
176: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
177: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can

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

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

215: a freed semaphore and corrupts heap;
216: - CLRERR is added to erase previous errors;
217: - ERRN and ERRM return exception message and number;
218: - major bug is fixed in interruptions.c. All signal are now bufferised
219: when semaphore_liste_threads is null to avoid deadlock. This bug only
220: occured when STOP was sent to a dying thread or process (when this thread or
221: process was running retrait_thread());
222: - matrix rank is computed before matrix inversion;
223: - file locks are added to stdin and stdout. stderr is not locked because
224: all messages written by signal handlers are sent to stderr;

299: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
300: process is killed;
301: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
302: know typeof() intrinsic function. This function is not standard but exists
303: under Sun Studio, gcc, and maybe some others compilers. If this function does

367: that all programs that worked with old SQL intrinsic can now work with
368: SQLQUERY. With all new programs, you can open a real connection to databases;
369: - NRPROC is added. This new intrinsic is used to catch error from child
370: process. Without NRPROC, any errors returned by child process cause
371: main process to abort;
372: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
373: starts a new process). There are no mutexes in RPL/2 because all spawned process
374: use specific context. Nevertheless, shared variables and associated mutexes
375: should be added;

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

1161: occurs when a syntax error is detected;
1162: - #error and #warning preprocessor macros are added;
1163: - INCR and DECR are written (with integer or variable argument);
1164: - CSWP and RSWP are added and tested;
1165: - a minor bug is fixed in analyse.c;
1166: - DEBIAN/control is added to build debian package;

1169: * Sun Apr 13 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6g (RPL/2)
1170: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1171: VISIT does not find a name in level 1;
1172: - configure.in script is modified to add a new test (--enable-debug
1173: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1174: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1175: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1176: 'MATRIX' { 2 2 3 } GETR;
1177: - LOGSCALE intrinsic is improved and now, it can be used as
1178: { "main" "auxiliary" X Y } LOGSCALE;
1179: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1180: same than AXES:
1181: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1182: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1183: { { -10 10 } "automatic" } SCALE.
1184: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1185: because it changes only the dimension of the screen. To have a logarithmic
1186: scale, you must use LOGSCALE intrinsic:
1187: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1188: screen on second scale;
1189: - { X X } autoscale and { Y Y } logscale are now invalid;
1190: - *D is added (depth multiplication, for 3D graphics);
1191: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1192: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1193: - a major bug is fixed in GETI instrinsic when it is used with a name
1194: that contains a matrix or a vector (bad upper bounds conditions in
1195: incrementation);
1196: - DISP intrinsic now uses the 33-th flag. When it is not set
1197: (default), a final carriage return is sent to the terminal;
1198: - AXES intrinsic only takes a list that can contains the keywork
1199: "main" or "auxiliary". Before this modification, this keyword was in
1200: the first stack level;
1201: - vim syntax file is upgraded;
1202: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1203: option;
1204: - LAST is now disabled in the main loop of INT intrinsic;
1205: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.

1207: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1208: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1209: in 0);
1210: - LAST is disabled in the main loop of DRAW intrinsic;
1211: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1212: evaluation of an equation, the system stack is returned corrupted to the
1213: sequencer;
1214: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1215: of a loop are not integer or real.
1216: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)

1218: have the same name. To improve the compilation() subroutine, I have to
1219: add some tests in gestion_variables.c;
1220: - recherche_type() subroutine ad some other connex subroutines are improved.
1221: Now, some syntax errors about object are caught and do not perform sequencer
1222: hangup;

1226: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1227: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown

1244: - a minor bug is fixed in evaluation subroutine;
1245: - vim syntax file is improved;
1246: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1247: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1248: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1249: is a quick and dirty workaround...);
1250: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1251: - rplconvert is improved.
