pike -x module install (7.7)
by Kaos 15 Oct '04

15 Oct '04

I'm having trouble with the .so not getting the __ prefix - anyone else know about this? About to compile a new 7.6 and test with that as well..

Note that Lua.pmod/ module.pmod creates a Dirnode in itself, so you still don't have the module program at hand. (So the result would actually be a Joinnode of a .so and a Dirnode.)

Re: port problem when update from 7.4 to 7.6
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 14 Oct '04

No, the only change was in how the main program (the one you name on the commandline) get instantiated. Modules get instantiated just like before. I don't see anything wrong with your Stdio.File() instantiation, so probably the problem is somewhere else in your code. / Marcus Comstedt (ACROSS) (Hail Ilpalazzo!)

memory leak in oracle module
by Michael J. Stenitzer ＠ Pike developers forum 14 Oct '04

14 Oct '04

[i moved this discussion to the developers' forum as i think it is more suitable for my problem.] thanks to martin and marcus for your hints for debugging. unfortunately it did not bring any results. what i did so far: * i discovered a memory-leak when i use roxen 4+ or chilimoon running with pike 7.4.*, 7.6.* (i have tested many different releases and fresh from cvs). this happens with a website connecting to an oracle db. memory demand grew to several hundred MBs within an hour or two of rather heavy requests. * this has been reproduced on three different hosts (all running linux). * roxen / debug information / Pike memory usage information shows more or less constant memory demand (total: 12000 kB). * the same website on roxen Pike v7.2 release 543 shows no memory leaks (constant memory demand ~38 MB). i used the same oracle libraries so i guess they are not leaking. * compiling pike 7.6 with-dmalloc and running roxen with: twice i managed to run and exit roxen cleanly but i got no memory leaks reported (last message was "counting bytes") * running hilfe with pike 7.6 with-dmalloc and doing some queries on oracle did also not report any memory leaks after exiting normally. * tried to run roxen or pike with valgrind but it failed. # valgrind --leak-check=yes --trace-children=yes --tool=memcheck (see error messages below) i have never used valgrind before and could not find any hints with google. anybody else knows how to use valgrind with pike? any further advice? /michael =====8<=====8<=====8<=====8<===== pike error messages when running with valgrind: /usr/local/pike/7.6.25/lib/master.pike:396: Failed to index module 'Files' with 'Stat' (module doesn't exist?) /usr/local/pike/7.6.25/lib/master.pike:1322: Failed to index module 'Files' with 'Stat' (module doesn't exist?) /usr/local/pike/7.6.25/lib/master.pike:2212: Failed to index module 'Files' with 'Stat' (module doesn't exist?) /usr/local/pike/7.6.25/lib/master.pike:2225: Cannot inherit program which is not fully compiled yet. /usr/local/pike/7.6.25/lib/master.pike:2230: Cannot inherit program which is not fully compiled yet. /usr/local/pike/7.6.25/lib/master.pike:3863: Failed to index module 'Builtin' with 'array_iterator' (module doesn't exist?) /usr/local/pike/7.6.25/lib/master.pike:4231: Cannot inherit program which is not fully compiled yet. /usr/local/pike/7.6.25/lib/master.pike:4238: No inherit or surrounding class Encoder. /usr/local/pike/7.6.25/lib/master.pike:4243: Cannot inherit program which is not fully compiled yet. / Michael J.

Pressrelease Pike Camp and Conference 2004
by Martin Bähr 13 Oct '04

13 Oct '04

hi please take the following pressrelease and send it to any news outfit you can think of. translate it to your language (a french translation is in the works) and send it to local technical news providers. any computer magazine, computer related news site, newsgroups, mailinglists that you are on. or any other place that might fit. ---------------begin pressrelease------------------------- - Pike - Caudium - sTeam - psycMUVE - LPC - October 13 - 19, 2004 Pike Users Worldwide Converge on Essen Next Week This years largest Pike event will be the Pike Camp in Essen, Germany from October 13th through the 19th. Users and developers of the Pike Language will be arriving in Essen from all over the world, including Sweden, USA, Latvia, Hungary, Austria, France and Germany for a week of talks, technical workshops and tutorials. Included in the week's events are the 3rd annual Pike Conference, 2nd annual Caudium conference, sTeam developer day and PSYC MODV: the 5th PSYC modification event. This year's keynote will be delivered by Uwe Aßmann, Chair of Software Engineering at Technical University of Dresden, on "Pike between UML and Java: a use case in University Education." All users and developers interested in Pike and its applications, including those new to Pike, are encouraged to attend any portion of the event. Beginner Pike tutorials will be held every day. Registration is ongoing, and more information is available from the Camp and Conference websites, found below. Additionally, you may contact the conference committee for additional information at conference(a)gotpike.org. About Pike Pike is a dynamic programming language with a syntax similar to Java and C. It is simple to learn, does not require long compilation passes and has powerful built-in data types allowing simple and really fast data manipulation. Pike is a reimplementation of the LPC language, its application domain spans anything from the world of the Net to the world of multimedia applications, or environments where your shell could use some spicy text processing or system administration tools. Your imagination sets the limit, but Pike will probably extend it far beyond what you previously considered within reach.

Mysterious segfault... solved by increasing -s...
by Alexander Demenshin 13 Oct '04

13 Oct '04

Hi, Playing with sqlite module (by Bill), got some mysterious segfault after ca. 140K rows were returned... It was completely mysterious, pointing to places like: push_text("val"); // I replaced original to test it... where all variable values were normal (according to gdb), but valgrind went crazy... Well... The story finished when I started pike with -s1000000 - everything is OK - despite the fact that processing of 1000000 rows takes ca. 500M or RAM :) So... The question... Isn't something that is controlled by -s (pike stack, I guess - values are accumulated on stack before aggregation) supposed to check stack size against oversizing? functions like push_* or whatever? To be honest, it took me few hours of hunting without any clue about reasons - and totally useless coredumps, valgrind reports, etc... Ah... It was tried with pike 7.6.24... Not sure if this is relevant, but I remember that early (some time ago) I got a message like "Stack overflow" from Pike, when it was too small (even without --rtl-debug etc.). NB: Bill, there are some troubles with sqlite3 support - I fixed them and will send a patch to you shortly... Unless you fixed those already :) Regards, /Al

port problem when update from 7.4 to 7.6
by Credence Shanden 13 Oct '04

13 Oct '04

Not sure why I am receiving this error. I just updated from 7.4 to 7.6 and now I get this error when I try to run my program. Too many arguments to Port->create(). Expected at most 1. Unknown program: Port->create(({"C:/EMAGE/kernel.pike"})) C:/EMAGE/kernel: C:/EMAGE/kernel(ANY:({ /* 1 element */ "C:/EMAGE/kernel.pike" }))->create(@0=({"C:/EMAGE/kernel.pike"})) C:/Program Files/Pike/lib/modules/Stdio.pmod/module.pmod:1277: C:/EMAGE/kernel(A NY:({ /* 1 element */ "C:/EMAGE/kernel.pike" }))->create(@01,0,0) All I am doing is inheriting Stdio.Port so I can use the bind function. This worked before in 7.4. Any help would be appreciated. _______________________________ Do you Yahoo!? Declare Yourself - Register online to vote today! http://vote.yahoo.com
