73: * Thu May 09 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.23 (RPL/2)
74: - major bug is fixed in STD format (1E7 sq prints 1);
75: - major bug is fixed in READ intrinsic (socket). This bug was introduced
76: by a new feature in glibc.
77: * Thu Apr 14 2011 BERTRAND Joël <rpl@systella.fr> rpl-4.0.22 (RPL/2)
78: - by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and
79: "ALL" IMPLICIT when it runs in interactive mode;
80: - when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used
81: to create or modify a global variable. Now, with "NONE" IMPLICIT, you have
82: to use SAVE to manipulate global variables;
83: - replace erroneous TAB by TBL in evaluation() and formateur_fichier()
84: subroutines;
85: - fix major memory access violation in evaluation subroutine. Only occurs
86: when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds;
87: - fix major bug in evaluation subroutine. 'X(i)' returns execution error
88: when X was a vector or a table.

1.57 bertrand 107: - Lapack is upgraded to 3.3.0;
1.58 bertrand 108: - libmtmalloc is now default Solaris allocator;
1.56 bertrand 109: - ncurses is upgraded;
1.60 bertrand 110: - regression introduced by 4.0.19 is fixed in signal management.
1.59 bertrand 111: Interruption1() could be called from itself and raises bus error (on sparc) or
1.55 bertrand 112: segmentation fault;
113: - sqlite is upgraded to 3.7.4;
1.54 bertrand 114: - OpenSSL is upgraded to 1.0.0c;

1.53 bertrand 117: - gnuplot is upgraded to 4.4.2 due to major bugs.
1.52 bertrand 118: * Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
119: - due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
120: Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
121: corruption. As internal memory management have been improved, a best fit
122: allocator like ptmalloc3 is not required anymore;
1.50 bertrand 123: - gnuplot is upgraded to 4.4.1;
124: - deadlock is fixed in signal handlers: same mutex was used in standard
125: subroutines (without protected sections by sigprocmask() or pthread_sigmask())
126: and signal handlers. A new signal handler specific mutex is added;
127: - minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function
128: that has to be evaluated by ->NUM;
1.49 bertrand 129: - rplfile build process is modify to be sure that rplfile is not modified
130: after rpl build stage (to be sure that rplfile checksum is not modified after
131: rpl compilation);
1.51 bertrand 132: - AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan,
133: modified to remove yacc code and renamed;
1.47 bertrand 134: - some workarounds have been written to not use buggy klibc SystemV IPCS.
135: ABORT now works on eComStation;
136: - sqlite is upgraded to 3.7.2;
137: - bug is fixed in software interrupts. When both process have different PID,
138: parent process was not interrupted if it is not group master process. To fix
139: this bug, SIGINJECT signal is not sent by child process but by control thread
140: in parent process;
1.46 bertrand 141: - minor bug is fixed in data injection (POKE) that does not work as expected
142: when child process is protected by NRPROC.
1.44 bertrand 143: * Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
1.43 bertrand 144: - --enable-sysv-sems is added to configure script to use SystemV semaphores
145: functions instead of POSIX functions. This function is disabled or forced on
146: systems that does not provide correct POSIX or SysV semaphores subsystem;
147: - a dirty but not quick patch is written to workaround broken siginfo
148: structures. This patch has been successfully tested. It uses a segment of
1.50 bertrand 149: shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process
1.43 bertrand 150: (Unix PID);
1.41 bertrand 151: - some OpenBSD's hacks are added;
152: - broken siginfo->si_pid field is now checked by configure script;
1.40 bertrand 153: - SWI now sends SIGCONT to interrupted process to start interrupt without delay;

1.39 bertrand 156: - getaddrinfo is hardcoded when host system does not provide getaddrinfo
1.40 bertrand 157: or freeaddrinfo;
1.39 bertrand 158: - RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
159: - major bug is fixed in CHR intrinsic when obtained character is not printable;

1.37 bertrand 167: - sqlite is upgraded to 3.7.0.1;
1.36 bertrand 168: - units is upgraded to 1.88;
169: - another major bug is fixed in the same variable creation subroutine.
170: Level 0 and 1 variables adresses were swapped when a global variable masked
171: a name of RPL/2 routine;
1.35 bertrand 172: - major bug is fixed in global variable creation subroutine. When a global
173: variable was created and when a local variable existed with the same name,
174: computed address of global variable was wrong;
175: - src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
176: is forced in front of all libraries.
1.34 bertrand 177: * Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
178: - BACKTRACE intrinsic is added;
179: - major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
180: when this structure is included in IFERR/THEN/END structure and when an error is
181: caught;
182: - major bug is fixed in analyse() subroutine. When evaluation() returned error
183: in a compiled program, analyse() caught this error twice and randomly aborted
184: with a segmentation error;
185: - TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
186: - ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
187: signals;
188: - memory leak is fixed in ROW+. It only occurs when a row is added to an empty
189: matrix.
1.33 bertrand 190: * Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
191: - minor bug is fixed in evaluation() subroutine. With this patch, same program

200: - -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
201: linux (false mremap() prototype);
202: - major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
1.30 bertrand 203: * Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
1.29 bertrand 204: - all '-' are replaced by '_' in random generator list;

208: format in FCH (file descriptor) and SCK (socket descriptor);
209: - debug routines are improved;
210: - PROCID is added;
211: - MEMLOCK and MEMUNLOCK are added. MEMLOCK forces a process to remain in memory
212: and to not use swap;
1.26 bertrand 213: - major bug is fixed in sql support. SQL connections were closed in all chield
214: process;
215: - standard allocator (malloc()/free()) is replaced by ptmalloc3 due to some bugs
216: discovered in Solaris thread safe allocators (libmalloc and libumem) that
217: are first fit class allocators. Solaris libmtmalloc works better and is
218: a best fit class allocator but its performance is poor than ptmalloc3
219: performance;
1.24 bertrand 220: - major bug is fixed in ROW+ intrinsic (new row was not added where it
221: should);
222: - minor bugs are fixed in interruptions.c (semaphores values when error is
223: caught);
224: - major bug is fixed in STOP intrinsic. STOP was unable to stop any process
225: created by SPAWN;
226: - SIGFABORT is added. When process receives SIGFSTOP, it tries to execute
227: ATEXIT. If it receives SIGFABORT, it does not;
1.23 bertrand 228: - ONEXIT is renamed in ATEXIT;
229: - ONEXIT new intrinsic is added.
1.20 bertrand 230: * Wed Apr 21 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.14 (RPL/2)
231: - major bug is fixed in static and shared variables initialization subroutine.
232: This bug only occurs when RPL/2 tries to create a shared or static variable
233: from an expression;
234: - major bug is fixed in copie_etat_processus(). A field that contains
235: information about shared variable was not copied to new processus structure;
1.19 bertrand 236: - some little memory leaks are fixed in evaluation(), recherche_type() and
237: sequenceur(). They only occured when syntax error were caught;
238: - IMPLICIT causes execution error instead system error;
239: - Hurd support is improved but currently broken because Hurd does not support
240: SIG_INFO. Work in progress;
241: - OpenBSD specific support is removed from sources;
242: - support for Mac OS X and Windows/Cygwin is added.
1.17 bertrand 243: * Wed Apr 07 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.13 (RPL/2)

358: - RPL/2 can now be run on EBCDIC systems (OS/390);
359: - major bug is fixed in -A command line option (NULL character is missing);
360: - minor bug is fixed in rpliconv and RECODE intrinsic. All transliterations are
361: made by blocks (1024 bytes). When an incomplete multibyte sequence is
362: encountered at end of block, subroutine aborts with an execution error;
363: - major bug is fixed in OPEN (TCP/IPv4 sockets).
364: * Mon Nov 30 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.7 (RPL/2)
365: - DISP now locks stdout;
366: - rpliconv is added to replace standard iconv provided by operating system.
367: Indeed, conversion between different encodages requires transliteration
368: that is not offered by some iconv utility;
369: - CURRENC and RECODE intrinsics have been written to allow strings conversions;
370: - bug is fixed in SYSEVAL. When execvp() returns (for example when arg[0] can
371: not be found), SYSEVAL enters in a dead lock;
372: - fprintf is replaced by some functions that allow transliterations between
373: locales;
374: - '"' can now be used in strings ("\"");
375: - iconv is called with -c in preprocessor stage. It is done to write
376: CGI scripts with RPL/2 because locale charset is set to ANSI_X3.4-1968;
377: - double free is fixed in liberation() (type SQL, only occurs when locale is
378: set);
379: - LOCALIZATION, UCASE and LCASE are added;
380: - major bug is fixed in EXIT intrinsic that was able to return a false
381: execution error in compiled scripts (only in DO/UNTIL and REPEAT/WHILE loops);
382: - major bug is fixed in wrapper_instruction_intrinseque(). When intrinsic() was
383: used in onLoading from shared library, USE was pushed on stack as algebraic
384: expression;
385: - libiconv is upgraded to 1.13.1;
386: - gnuplot is upgraded to 4.2.6;
387: - gsl is upgraded to 1.13.
388: * Mon Sep 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.6 (RPL/2)
389: - pipe() is overwritten by a macro to avoid a system error. Communication
390: between process are done with pipes and these pipes are managed by a
391: specific asynchrone thread. If a script try to create more threads than
392: management thread can destroy, you can quickly achieve maximum number of
393: opened files and pipe() shall return a system error. This macro tries to create
394: pipes. If pipe() function returns an error, macro waits and retries. If
395: number of retries is greater than a hardcoded value, macro returns an error;
396: - major bug (deadlock) is fixed in process and thread management. I hope
397: this bug shall be the last one;
398: - major bug is fixed in DET intrinsic (determinant was computed without LU
399: diagonalization);
400: - SWAPCNTXT is added;
401: - minor bug is fixed in Makefile.am (licences rule).
402: * Wed Sep 09 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.5 (RPL/2)
403: - some bugfixes are added in process management;
404: - all process management is rewritten to avoid usage of defunct process
405: or thread number;
406: - new major bug is fixed in interruptions.c. Sometimes, when retrait_thread()
407: was called before a pending interruption5 (SIGFSTOP), signal handler uses
408: a freed semaphore and corrupts heap;
409: - CLRERR is added to erase previous errors;
410: - ERRN and ERRM return exception message and number;
411: - major bug is fixed in interruptions.c. All signal are now bufferised
412: when semaphore_liste_threads is null to avoid deadlock. This bug only
413: occured when STOP was sent to a dying thread or process (when this thread or
414: process was running retrait_thread());
415: - matrix rank is computed before matrix inversion;
416: - file locks are added to stdin and stdout. stderr is not locked because
417: all messages written by signal handlers are sent to stderr;
418: - configure.in script is modified to test gcc version and avoid a bug in
419: gcc older than 4.4;
420: - some benchmarks have been done :

489: - --enable-profile flag is added to configure script. When this flag is
490: enabled, rpl is built with -pg option;
491: - SIGFSTP (from Solaris'TERMIO) is caught. On Solaris 10, all process receive
492: SIGFSTP (with a nullified siginfo structure) instead of SIGHUP when control
493: process is killed;
494: - abs() macro is modified to avoid multiple evaluation. Your C compiler has to
495: know typeof() intrinsic function. This function is not standard but exists
496: under Sun Studio, gcc, and maybe some others compilers. If this function does
497: not exist on your compiler, you can change its definition by old one in
498: src/rpl.h;
499: - fflush() can now be interrupted by signal (SunOS);
500: - fflush(NULL) is called before all fork() occurrences;

521: deadlock when a huge amount of threads is launched);
522: - minor bug is fixed in boath START and FOR intrinsic. Only occurs when
523: arguments types are unsupported;
524: - PLOT instrinsic is added (usage: LINE and MARK do not draw anything. All
525: data are buffered. PLOT is used to draw these objects.);
526: - MARK instrinsic is added;
527: - new allocator mechanism is written;
528: - some regression bugs have been fixed, some memory leaks too.
529: * Wed Jan 28 2009 BERTRAND Joël <rpl@systella.fr> rpl-4.0.0.prerelease.9 (RPL/2)

539: static variable that is shared by multiple threads;
540: - '->' intrinsic is improved. All object copies have been avoided;
541: - -n flag is added to catch HUP signal. stderr and stdout are redirected
542: to a file, stdin is redirected to /dev/null when control process is killed;
543: - a mutex is added to each object (before this modification,
544: RPL/2 used a global mutex and performances in multithreaded programs were very
545: poor.);

559: in three new intrinsics : SQLCONNECT, SQLQUERY and SQLDISCONNECT. Please note
560: that all programs that worked with old SQL intrinsic can now work with
561: SQLQUERY. With all new programs, you can open a real connection to databases;
562: - NRPROC is added. This new intrinsic is used to catch error from child
563: process. Without NRPROC, any errors returned by child process cause
564: main process to abort;
565: - SPAWN is added. This new intrinsic is used to launch a new thread (DETACH
566: starts a new process). There are no mutexes in RPL/2 because all spawned process
567: use specific context. Nevertheless, shared variables and associated mutexes
568: should be added;
569: - -D flag and DAEMONIZE intrinsic have been added;

619: - ->TABLE and TABLE-> intrinsics are added;
620: - major bug is fixed in recherche_type(). Only occurs when rpl executes
621: precompiled scripts;

639: nullified lists;
640: - rplexternals.h is modified and improved;
641: - GNU File (renamed as rplfile) cannot be built due to a bug in libtoolize and

654: - FUSE, RFUSE and CLRFUSE have been added;
655: - new bug discovered on NetBSD. sigpending() does not return any signal, thus
656: DETACH intrinsic enters in a definitive dead lock. I have no idea to write a
657: workaround for this major bug. Nevertheless, all others capabilities seems to
658: work fine;
659: - '->' is modified to return error when program tries to initialiaze two

707: before starting interrupt evaluation;
708: - -f parameter is added when iconv is called;
709: - as old file program was bugged, a new option is added to configure script.
710: When configure is called with --disable-encoding-autodetection, make does not
711: try to detect source encoding. Please, do not use if RPL/2 can be built
712: without this option !
713: - new garbage collector (and more efficient) is written;
714: - configure script is modified to be usable on NetBSD 4.0, but as NetBSD does
715: not support real time signals, RPL/2 cannot use multitasking functions;
716: - error returned by preprocessor are now catched by RPL/2;
717: - -p option is added. With this option, all scripts are compiled before
718: RPL/2 starts evaluation. HALT cannot be used with -p, but all programs run
719: 40% faster;
720: - read and write operations in pipe() are rewritten to be sure that such
721: operations are atomic;

863: - external wrapper (rplplot) is written to force usage of gnuplot provided
864: by RPL/2 if it is built during build process. If this build does not exist,
865: it tries to launch regular gnuplot;
866: - gnuplot is added to source tree to avoid some trouble between preinstalled
867: gnuplot and release used by RPL/2. This addition to source tree is
868: required by some incompatibility between gnuplot releases;
869: - Lapack is upgraded to 3.1.1 release;
870: - GSL is upgraded to 1.9 revision;

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

1246: fine...);
1247: - NOT is not correctly formatted in formateur.c:
1248: Z NOT -> 'NOT Z' but 'A+Z' NOT -> 'NOT A+Z' and 'NOT Z+A' -> 'NOTZ+A'
1249: with a NOTZ function !
1250: * Sun Aug 10 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre7c (RPL/2)

1253: - RPL/2 is tested with efence and valgrind;
1254: - configure.in script is modified;
1255: - units.c is modified to be built by gcc-3.3. I only have removed a #if 0/#endif

1316: appear on the same figure). The same mistake is fixed in DRWS intrinsic;
1317: - LAST is disabled in evaluation subroutine (EVAL and ->NUM intrinsics).
1318: * Sun May 18 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6j (RPL/2)

1335: - SCLS is added;
1336: - DRWS now uses COLS to draw 2D graphics;
1337: - PPAR and SPAR are written. SPAR returns a list that contains the
1338: size of the statistical matrix (or "UNAVALAIBLE" if there is any
1339: statistical variable, or "DISABLED" if its type is not one of the type of
1340: a statistical matrix.) and XCOL and YCOL parameters. Warning: [[]] SIZE
1341: returns { 1 0 } and it is not a bug, because a null matrix contains _one_
1342: null line ! Thus, [[]] STOS SPAR returns { { 1 0 } 1 2 };
1343: - EXTERNAL intrinsic is added. Warning: by default, extern functions are
1344: disabled. Arguments of EXTERNAL are case sensitive because the external
1345: interface is written in C. { ext_sinus } EXTERNAL does not replace the list
1346: of known external functions but add the new list to the last. { "all" }
1347: EXTERNAL allows all external functions and { "none" } EXTERNAL removes all
1348: external names of the known functions;
1349: - mkrplso.in is modified.
1350: * Sun Apr 20 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6h (RPL/2)
1351: - vim syntax file is upgraded;
1352: - a minor mistake is fixed in recherche_instruction_suivante();

1363: - a very minor bug is fixed in VISIT intrinsic. It only occurs when
1364: VISIT does not find a name in level 1;
1365: - configure.in script is modified to add a new test (--enable-debug
1366: flag). Configured with this fleg, RPL/2 will be built with electric-fences;
1367: - GETR (get row[s]) and GETC (get column[s]) are added. These new instructions
1368: extract a part of a matrix. Syntax: [[ 1 2 3 ][ 2 3 4 ]] { 1 } GETR or
1369: 'MATRIX' { 2 2 3 } GETR;
1370: - LOGSCALE intrinsic is improved and now, it can be used as
1371: { "main" "auxiliary" X Y } LOGSCALE;
1372: - SCALE intrinsic is used to fix the limits of a graphic. Its syntax is the
1373: same than AXES:
1374: { { 60 "ticsonly" 2 } { "automatic" "ticsonly" 10 } } axes
1375: { "auxiliary" { 60 "ticsonly" "default" } { "automatic" } } axes
1376: { { -10 10 } "automatic" } SCALE.
1377: Warning, it is not possible to ask a logarithmic scale with this intrinsic
1378: because it changes only the dimension of the screen. To have a logarithmic
1379: scale, you must use LOGSCALE intrinsic:
1380: { X } LOGSCALE gives a semi-log screen, { "auxiliary" X Y } gives a log-log
1381: screen on second scale;
1382: - { X X } autoscale and { Y Y } logscale are now invalid;
1383: - *D is added (depth multiplication, for 3D graphics);
1384: - a new intrinsic (*S) is added. It changes the scale of a graphic (X, Y
1385: and Z axes). The result of *S is the same than DUP DUP *H *W *D;
1386: - a major bug is fixed in GETI instrinsic when it is used with a name
1387: that contains a matrix or a vector (bad upper bounds conditions in
1388: incrementation);
1389: - DISP intrinsic now uses the 33-th flag. When it is not set
1390: (default), a final carriage return is sent to the terminal;
1391: - AXES intrinsic only takes a list that can contains the keywork
1392: "main" or "auxiliary". Before this modification, this keyword was in
1393: the first stack level;
1394: - vim syntax file is upgraded;
1395: - in appel_gnuplot(), stdin is closed when gnuplot is called with -raise
1396: option;
1397: - LAST is now disabled in the main loop of INT intrinsic;
1398: - expm1 and lnp1 are rewritten to use expm1 and log1p from math.h.
1399: * Sun Apr 6 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6f (RPL/2)
1400: - a major bug is fixed in evaluation() subroutine. It occurs with DRAW
1401: intrinsic when the equation cannot be evaluated (for example 'SIN(X)/X'
1402: in 0);
1403: - LAST is disabled in the main loop of DRAW intrinsic;
1404: - a major bug is fixed in DRAW intrinsic. When an error occurs in the
1405: evaluation of an equation, the system stack is returned corrupted to the
1406: sequencer;
1407: - the same minor bug is fixed in FOR and START. It only occurs when the limits
1408: of a loop are not integer or real.
1409: * Sun Mar 31 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6e (RPL/2)
1410: - the compilation stage aborts with an error message when two definitions
1411: have the same name. To improve the compilation() subroutine, I have to
1412: add some tests in gestion_variables.c;
1413: - recherche_type() subroutine ad some other connex subroutines are improved.
1414: Now, some syntax errors about object are caught and do not perform sequencer
1415: hangup;
1416: - readline is upgraded (minor compilation bug with recent gcc);
1417: - Makefile.am's and configure.in scripts are improved.
1418: * Fri Mar 14 2003 BERTRAND Joël <rpl2@systella.fr> rpl-4.00pre6d (RPL/2)
1419: - DRWS intrinsic is written. Two datastyles are associated: SCATTER (2D
1420: and 3D) and HISTOGRAM (only 2D, but 3 columns are accepted, the third shown
1421: the boxwidth, 1 by default);
1422: - recherche_type() is rewritten to be faster;
1423: - gsl is upgraded (release 1.3);
1424: - ncurses is upgraded and patched (release 5.3);
1425: - recherche_instruction_suivante() is fixed (string research with included
1426: '"') and rewritten to be faster;

1437: - a minor bug is fixed in evaluation subroutine;
1438: - vim syntax file is improved;
1439: - DRAW (wireframe section) is fixed. When an error occurs in the evaluation
1440: of a 3D-graphic (for example 'SIN(R)/R' with 'R=SQRT(X**2+Y**2)' in X=0 and
1441: Y=0), no graph was procuced (it results from a bug in gnuplot, and this fix
1442: is a quick and dirty workaround...);
1443: - RETURN intrinsic is modified to fix a trouble in interactive mode;
1444: - rplconvert is improved.

1544: signal is an asynchonous "HALT" command;
1545: - SIGINT (CTRL+C) variables stack corruption is fixed;
1546: - IFERR seems to be fixed (in equation evaluation routine);

1554: i586, i686, K6, K7, alpha ev4, alpha ev5, alpha ev56, alpha ev6, sparc v7,
1555: sparc v8 and sparc v9. Compilation of RPL/2 on my Sun Sparc 2 (sun4c,
1556: CPU 4/75, 64 MB, 40 MHz with FPU) is a very great mission :
1557:
1558: Newton:[~/rpl/rpl] > time make install
1559: ...
1560: real 338m39.623s
1561: user 324m32.290s
