Forum OpenACS Development: problems with tcl threads2.6 and aolserver4

I'm trying load aolserver4 with libthread2.6.so from tcl threads 2.6 and these errors are occurring (aolserver error log):

[30/Dec/2004:15:41:43][8945.1024][-main-] Notice: modload: loading '/usr/local/aolserver/lib/thread2.6/libthread2.6.so'
[30/Dec/2004:15:41:43][8945.1024][-main-] Warning: modload: could not find Ns_ModuleInit in /usr/local/aolserver/lib/thread2.6/libthread2.6.so
[30/Dec/2004:15:41:43][8945.1024][-main-] Fatal: modload: failed to load module '/usr/local/aolserver/lib/thread2.6/libthread2.6.so'

threads2.6 was installed as a loadable module for the AOLserver with this config options:

aoldir="/usr/local/aolserver"
../configure --enable-threads --with-aolserver=$aoldir \
--prefix=$aoldir --exec-prefix=$aoldir

In my aolserver config.tcl I have:

ns_param libthread ${homedir}/lib/thread2.6/libthread2.6.so

Maybe this error is related with this warning in threads CONFIG:

#
# AOLserver uses its own package loading mechanism.
# To load, just do "ns_eval package require Thread"
# at the AOLserver startup or later from any thread.
#

but when i add "ns_eval package require Thread" to aolserver4 config.tcl the server doesnt load and doesnt write to log file.

What am i missing?

It is very strange! The only way i could have libthread2.6 compiled with Ns_ModuleInit was changing by hand generic/aolstub.cpp to

/* #ifdef NS_AOLSERVER */
#include "/usr/local/aolserver/include/ns.h"

althroug my CONFIG was passing parameter "--with-aolserver" the var NS_AOLSERVER was not setting. I do not know why.

This way i could have as a result from "nm libthread2.6.so|grep Module":

00001654 T Ns_ModuleInit
00011b6c D Ns_ModuleVersion

and libthread2.6.so module was loaded correct by aolserver when declaring "ns_param libthread ${homedir}/lib/thread2.6/libthread2.6.so" in modules section.

Problem now is with throttleThread 😟

When I put your modules/tcl/*xotcl files in my aolserver dir modules/tcl/ and reload aolserver thats ok. Server is up but every page i browse nothing happens and this message is written in aolserver log errors:

"throttleThread do ::throttle check 200.181.95.53 200.181.95.53"
("eval" body line 1)
invoked from within
"eval [my server] do [self] $args"

(procedure "check" line 11)
::throttle->check
invoked from within
"my check"
(procedure "postauth" line 4)
::throttle->postauth

"throttle postauth"

(xotcl 1.3.4 is installed with make-aol; xotcl.tcl is in $aoldir/modules/tcl/ and *xotcl files are sourced because when i remove them the website pages display fine without any error):

Maybe errors in throttle_mod.xotcl script (as Malte observed)?

Thank you for your patience.

Thanks, Gustaf.

I am working now in a brief tutorial about how Gustaf help me to install requirements for xotcl-stuff and soon i will post it in this forum. Maybe other people could try it.

My threadPoolCmd.c version is newer than v 1.26

* RCS: @(#) $Id: threadPoolCmd.c,v 1.28 2004/11/27 06:11:02 vasiljevic Exp $

i downloaded threads2.6 from tcl.sf.net: http://prdownloads.sourceforge.net/tcl/thread2.6.tar.gz?download

following changes were introducing in v 1.28 over v 1.26 (directly from cvs):

Unfortunately xotcl-stuff still doesnt work in my openacs-5-1-3 + dotlrn-2-1b install. Errors:
