Sorry, I didn't mean to ignore Nilssons Int.inf class, but I was referring to a real bignum Int.inf there.

oracle module (again!)
by Michael J. Stenitzer ＠ Pike developers forum 28 Oct '04

28 Oct '04

after the fixing of the memory leak and another bug we still encounter problems with the oracle module. after successful tests at our testserver we moved on to our production server and did some performance tests there (using 7.4.169 and roxen 4-cvs). this is a linux-smp server (the other one is a single processor machine running also linux). as soon i start tests with concurrent requests the process immediately hangs and the server restarts. peter holzer (our sys-admin) thinks that this might be a thread problem. BTW: mysql connections are fine. /michael

Except of course when the C-module allows for concurrent operations e.g. when making SQL queries, processing images, hashing data and other operations that doesn't affect Pike structures until completed. On a webserver the OS and the DBM typically also needs CPU time, and they are not bound by the intepretator lock.

Much threaded pike-code runs noticeably faster on a SMP machine. The reason is somewhat obvious: The lock is released for most operations that take significant time (such as image operations, database queries, I/O etc) Also, having an extra CPU for any databases and other external programs, and the system itself for that matter, really helps a lot.

Pike Camp and Conference Wrap-up
by Bill Welliver 28 Oct '04

28 Oct '04

I've posted a wrap up article covering hilights of last week's Pike camp and conference. You can view the wrap-up (as well as the initial press release and a listing of sites that published it) at: http://camp.gotpike.org/press/ Look for campreport.english.html. We'd also like to get translations of the article and submit it to the various online news outlets in order to maximize exposure. If you're able to translate and or submit this article, that would be great. There are a list of sites that posted the initial pressrelease, so they seem to be definite places to submit the article to. If anyone has any questions or needs help, please don't hesitate to contact us at conference(a)gotpike.org. Thanks in advance! bill welliver and martin baehr camp/conference co-chairs conference(a)gotpike.org

Redirecting stdio
by Kaos 26 Oct '04

26 Oct '04

Howdi gurus :) I'm trying to redirect my stdin/stdout/stderr when using Process.create_process. This far, I only get data through first when the file gets closed. I would much prefer to have them in a non-blocking fashion - any way to get this? (tried PROP_NONBLOCKING and set_nonblocking( read_cb, write_cb ) without success... )...

cmod vars to pike
by Kaos 25 Oct '04

25 Oct '04

Hi, How do I go about to map variables from a cmod to pike? I've found map_variable( "name", "type", flags, offset, pike_type ) but it comes along with a few questions. Can I only map struct object|string|array|... stuff from my Foo_program struct, or c stuff as well? like a foo * (or foo[]) treated as an array (guess not, so I'm about to make a struct array of my foo[]).. I'm only needing it for read only, but what happens if written to?

stralloc

If the dnl-prefixed lines in SQLites testsuite is enabled and the testsuite is run, Pike hangs in internal_findstring in stralloc.c. With dmalloc I get **Block: 0x97c7090 Type: string Refs: -1 **size_shift: 2, len: 1, hash: b31e0f9c Locations that handled 0x97c7090: (gc generation: 1/1 gc pass: 0/0) *** /home/nilsson/Pike/7.7/src/builtin_functions.c:1505 sub_ref (2 times) *** /home/nilsson/Pike/7.7/src/las.c:718 sub_ref (2 times) *** /home/nilsson/Pike/7.7/src/las.c:5455 sub_ref (1 times) *** /home/nilsson/Pike/7.7/src/mapping.c:253 sub_ref (1 times) *** /home/nilsson/Pike/7.7/src/mapping.c:2007 sub_ref (2 times) *** lexer0.h:672 sub_ref (2 times) *** /home/nilsson/Pike/7.7/src/interpret_functions.h:297 add_ref (2 times) *** /home/nilsson/Pike/7.7/src/las.c:1179 add_ref (2 times) *** /home/nilsson/Pike/7.7/src/mapping.c:747 add_ref (2 times) *** /home/nilsson/Pike/7.7/src/program.c:5239 add_ref (1 times) *** /home/nilsson/Pike/7.7/src/stralloc.c:698 add_ref (2 times) --> /home/nilsson/Pike/7.7/src/post_modules/SQLite/testsuite.in:55: Test 18 (shift 0):0 (1 times) *** /home/nilsson/Pike/7.7/src/builtin_functions.c:1505 (2 times) *** /home/nilsson/Pike/7.7/src/las.c:5455 (1 times) *** /home/nilsson/Pike/7.7/src/mapping.c:2007 (2 times) *** /home/nilsson/Pike/7.7/src/post_modules/SQLite/sqlite.cmod:220 (2 times) *** /home/nilsson/Pike/7.7/src/stralloc.c:385 (1 times) *** /home/nilsson/Pike/7.7/src/stralloc.c:535 (1 times) *** /home/nilsson/Pike/7.7/src/stralloc.c:1405 (1 times) *** lexer0.h:672 (2 times) ******************* Is this a problem with stralloc?
