[AOLSERVER] New nsjk2 Module Available
The AOLserver Team is pleased to announce the availability of the preview release of the nsjk2 module for AOLserver. nsjk2 integrates generic Java Servlet and Java Server Page functions with ability to filter HTTP requests in AOLserver, route them to Tomcat, and route Tcl evaluation calls from Java to Tcl interpreters that live within AOLserver connection threads. The source code has been submitted to the Jakarta Community for acceptance into the Jakarta core. We've decided to let everyone know about it now so that people can begin trying it out, and also in hopes of garnering some support for this module from those in the AOLserver Community who find it useful. In order to speed up the acceptance of this new module, we need your help. If this is something you'd be interested in using, please send an e-mail to the Jakarta Team ([EMAIL PROTECTED]) and let them know. Until the code is formally accepted, you'll need to download it from here: http://issues.apache.org/bugzilla/show_bug.cgi?id=18283 Full documentation can be found here: http://www.aolserver.com/docs/nsjk2.pdf Please refrain from submitting any bugs until the Jakarta Team has had a chance to set up an area in the Bugzilla database specifically for this module. Many thanks to Alex Leykekh for all of his hard work on this module and corresponding documentation!

[AOLSERVER] fix for Ns_MutexDestroy in 3.5 mutex.c
_mutexdestroy wasn't checking for a busy (locked by another thread) mutex:
-Jonathan
(Appologies if this is not the right forum, but the sourceforge patches
page doesn't look very busy.)

Re: [AOLSERVER] AOLserver 4.x and MacOSX: cwd problem
http://www.apple.com/macosx/feedback is where i usually report any bugs to apple. and most of the bugs i've reported through that page have been fixed.

The Tcl8.4.x uses the OS-call realpath() to figure-out the real physical path of the file on the filesystem, stripped of all "./", "../", constructs, symlinks and alike. BANG: this function uses chdir/fchdir internally which changes the process current working directory for each invocation. It is called for just about *every* path you pass to the Tcl library! Wow! The funny thing: the man page does not care to mention this *important* side-effect! This is truly sick, Zoran. Truly sick. An extremely obnoxious side-effect, even if it were documented. Does Apple have a process for filing bug reports that would give us some hope one of their Unix hackers will see it? -- Don Baccus Portland, OR http://donb.photo.net, http://birdnotes.net, http://openacs.org -- 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 - http://www.aolserver.com/ To Remove yourself from this list: http://www.aolserver.com/listserv.html List information and options: http://listserv.aol.com/
Re: [AOLSERVER] CGI memory leaks
Scott,
Here are the three different teset scripts we used
CGI:
-
#!/usr/local/bin/perl
use CGI;
my $string = "Simple Page";
$query = new CGI;
print $query->header;
print("$string");
$query->delete_all();
exit(0);
---
ADP (no exec):
---
<%
set string "Simple Page"
ns_return 200 text/html $string
%>
---
ADP w/ exec:
---
<%
set string "[exec date]"
ns_return 200 text/html $string
%>
---
The nsd.tcl file is attached. I believe it is mostly the standard one
that comes w/ debian with a few tweeks to get CGIs enabled.
Thanks,
Matthew
