[Mod-pubsub-developer] Re: running mod_pubsub_2004-04-20 with mod_perl

[<mod...@li...>]

I can answer portions of my own questions at this point.  If others 
have tried to run the old Perl server recently, perhaps they're running 
into the same problems.  I should have mentioned that my OS is FreeBSD 
5.3, since that could be relevant for the libraries used.  I have Perl 
5.8.6 installed.

My confusion about clients and servers was cleared up by looking at the 
code for pubsub_test.cgi.  It mentioned that you can run it at the 
command line (as you can any script that uses CGI.pm).  You do need to 
set some environmental variables to feed it the arguments it would get 
when called from a browser.  In any case this lets you test the server 
setup by running scripts on the server, so you're not dependent on any 
browser details.

After some experimentation I found that most of the tests were failing 
because PubSub::Server was failing to flush its output buffers.  There 
is a 300 second delay built into the code, so if you sit around long 
enough, you get to see the test fail.  If you're less patient, you 
think it's hung.  I added commands to flush the output buffers after 
three "send" commands in Server.pm, after which the majority of the 
tests gave an "OK" report.  So far I still don't understand why the `$| 
= 1;' command in PubSub::Server->route_to_javascript doesn't do the 
trick.  I had presumed it would force unbuffered output, and I haven't 
found anything in the Apache 2 or mod_perl documentation to suggest 
anything to the contrary.

With these patches all tests but the last two -- replay of events and 
replay of events with warp factor -- are now OK.  I have yet to explore 
the nature of these failures.  Are they something I should worry about?

If there is an interest in updating the software or the INSTALL 
document, please let me know, and I can attempt a slightly more 
coherent description of what I've found.

Thanks,
Bob Carlitz
