Yeah, we goofed the 2.0.4 release and mistakenly omitted it, its fixed 
or will be for 2.0.5.


Thanks for the feedback.

[mp2] Win32 Apache2.2.9 + AP5.10.0 + MP2.04 = OK

[Foo JH]

Hi all,

Recently started testing the a/m stack. Happy to report: so far so good:
1. Apache can be restarted via ApacheMonitor.exe
2. Works with libapeq2.6.3
3. Survives multiple restarts
4. Works with Apache2::Reload

Disclaimer: I'm not hard-core mp2, so the tests are wy surface-grade .

A point to note: Apache2::Reload is not available as part of the ppd
installs. However I was able to simply copy out the relevant folders in
the source to Perl/site/lib/, and it works w/o further intervention.

Protecting a mod perl 1.3 site from slow MySql processes

[April Papajohn]

Hello,

I am working on a site that has a modperl (mod_perl 1.3, perl 5.8.0, on linux)
handler doing some authentication work via DBD::MySql. It connects to
a MySQL server over the network.

Recently during some maintenance on the MySql server, the entire site
was hung up, because the MySQL server was up, but it wasn't
responding. It is important that the site continue to function, even
if MySql is down or slow.

I was able to reproduce something like what may have happened simply
by pausing the MySql thread in my test environment. If I do that, the
web page does just hang.

The perl module wasn't dying, so wrapping everything in eval{} won't
solve the problem.

I tried setting alarm() around the DBI lines, using the Sys::SigAction
module, in order to get the script to timeout if MySql isn't
responsive. This works great if I run it as a plain perl script. But
it seems that alarm()  doesn't work when it runs as a perl module.

So now I'm stuck.

I'm just looking for suggestions for possible solutions. Any way that
I can safe guard the site against a misbehaving MySql server.

Thanks,
April

You may be running different versions of perl or DBI in your script.
Signals are tricky when using some DBD drivers.  I suggest looking at
DBIx::Timeout for some information on this.

Realistically, it's not practical to wrap every single DBI call that
might hang if the server went away in the middle.  However, you can
adjust how long MySQL will wait to connect or timeout a dead
connection, and you can use something like Apache::DBI or
DBI-connect_cached which will ping your connection at the beginning
of a request.

Apache2-AuthenNTLM-0.02 - multiple domains issue

[maniac]

Hi Speeves,

i'm trying to get this package working as I need to do authentication for
apache users towards two separate NT domains.

For one domain it works OK, but not for multiple (two) domains.
What I found is that only defaultdomain PDC is being contacted neverthless
on what domain user specified in dialog box of her browser.

I'm using this configuration:

Apache/2.0.59 (Unix) mod_ssl/2.0.59 OpenSSL/0.9.8a DAV/2 PHP/4.4.4 
mod_perl/2.0.4 Perl/v5.8.8

Apache2-AuthenNTLM-0.02

and config files looks like this:

bash-3.1# cat ~maniac/public_html/auth/.htaccess
PerlAuthenHandler Apache2::AuthenNTLM
PerlAddVar ntdomain  ABCD  abcd00 abcd01
PerlAddVar ntdomain  EFGHIJKL  efgh00 efgh01
PerlSetVar defaultdomain ABCD
PerlSetVar fallbackdomain EFGHIJKL
PerlSetVar splitdomainprefix 1
PerlSetVar ntlmdebug 10
PerlSetVar ntlmauthoritative off
bash-3.1# 

bash-3.1# egrep '^KeepAlive' /usr/local/apache2/conf/httpd.conf

As you can see, i'm using my firefox, entering login name EFGHIJKL\xyz, but 
module is trying to connect to servers of domain ABCD instead of EFGHIJKL.

I'm confused also why there is no domain\user specified in line [433] 
AuthenNTLM: Object exists user = \ , and later, there is line with correct 
user and domain: [433] AuthenNTLM: protocol=NTLMSSP, type=3, user=xyz, 
host=analog, domain=EFGHIJKL, msg_len=0

Many thanks,

maniac
