Re: [AOLSERVER] AOLSERVER and an infinite loop
Couple of quick questions to help us help you:
- What version of the server are you using?
- Do you have a stack trace from the core file?
- Anything odd in the server log right before the crash (or did you
mean it never actually crashes)?
- Are you testing a C module you wrote, or some page code?
- Are you using mutex locks - maybe you are simply dead locked?
One other thing you could do is to check the connection thread stats -
if the endless loop is in your page code, it should be reasonably
isolated to the connection threads it was executed in. You can do this
from the control port:
server1:nscp 1> join [lsort [ns_info threads]] \n
...
-conn1- -nssock- 103 0 1048543624 connthread {320 10.4.44.252 running
GET /index.adp 2 0}
...
The second to last number (2 in this case) is elapsed time in seconds
for the request. You should see this number keep increasing for the
connection thread in question.
Another technique would be to add simple debug log notices before and
after suspect code:
ns_log notice "locking $lock ..."
ns_mutex lock $lock
ns_log notice "locked $lock ..."
# questionable code here
ns_log notice "unlocking $lock ..."
ns_mutex unlock $lock
ns_log notice "unlocked $lock ..."

Re: [AOLSERVER] nsxml indent
Send me the patch and tell me what the previous version was (i.e. is it the current CVS copy that doesn't do what you expect?). /s. On Monday, March 24, 2003, at 02:35 PM, Daniel P.

Actually, what is happening here is that what you're describing as "2nd session" is a running thread at the time of the ns_eval of the first. It won't get your update until it exits. The same would be true of any code you ns_eval-ed there. -- michael __ michael richman princ software engineer aol infrastructure dev 214.442.6048 -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list: http://www.aolserver.com/listserv.html List information and options: http://listserv.aol.com/

[AOLSERVER] Bug: namespaces and ns_eval
Hello,
I discovered that ns_eval command in control port doesn't process
namespaces correctly under AOLserver 4.0. Use case follows.
namespace eval mytest {}
proc mytest::mytest {} {}
1. start 2 nscp sessions, and load above code snippet into 1 of them
with "ns_eval source ..." command
2. in 2nd session, run command "info command mytest::*". It is expected
to return mytest::mytest, but returns nothing. This is wrong.
3. start 3rd nscp session and run command "info command mytest::*". This
time return is correct.
Thanks!
Alex

Re: [AOLSERVER] Community Sites (why PHP?)
Why not. ;-) The top AOlserver page is still being hosted on SourceForge. There are plans to move the top page back to being AOLserver hosted in the near future. AOLserver supports a number of other languages in addition to Tcl, including PHP, Python, Java, and others. I'm personally not all that familiar with the pro's and con's of PHP as compared against these other languages, so I'd recommend checking out their site for more info: http://www.php.net. - Nathan On Monday, March 24, 2003, at 11:20 AM, Ayan George wrote: Why would we use php? -ayan -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list: http://www.aolserver.com/listserv.html List information and options: http://listserv.aol.com/

[AOLSERVER] [AS 4.0 beta 3] Strange db pools error
Hi all, I am getting troubles switching from AS3.2/Tcl7.6 to AS4.0/Tcl8.4.2 I have 3 pools configured in my config file : main, subquery and log. Using nscp, when I run this code : set a [ns_db gethandle main] set b [ns_db gethandle subquery] it runs fine under AS3.2/Tcl7.6, but crashes under AS4.0/Tcl8.4.2 saying : thread already owns one handle from pool "subquery" on the second line ! It looks like the 3 pools are handled as the same pool under 4.0. When I try "ns_db pools", I get "main subquery log" under 3.2 et 4.0 ... so I am a little bit lost ! For info my config file looks like : ns_section "ns/db/pools" ns_param main "Oracle8 main database" ns_param subquery "subquery" ns_param log "log" ns_section "ns/server/fr.dev/db" ns_param pools* ns_param defaultpool main Thanks a lot for any tip.
