[mp2] HTML::Mason and Missing content
We're seeing some very strange behavior with HTML::Mason/Apache 2.2/MP2 that only affects a few of our files. I'm able to reproduce it reliably. We have a custom handler method that handles all requests to our site by passing them off to HTML::Mason (with exceptions for images, and the like). On some pages, the first few lines of HTML output are missing. If I add a newline to the very first line of the mason component, all of the content appears (see below). This has led me to believe that the issue is related to headers. Something is eating the first few lines of all out our output up until the the first blank line. Those lines however, do not appear in the header output of the request, though. They just seem to disappear somewhere inside apache2.2. Has anyone seen this problem before? We didn't experience it under MP1.

what handler phase as we in?
I have a module that does authentication and authorisation. In my Apache configs I have: PerlAuthenHandler Apache2::AuthX::authenticate PerlAuthzHandler Apache2::AuthX::authorise I'd rather just use: PerlAuthenHandler Apache2::AuthX PerlAuthzHandler Apache2::AuthX and let the handler function Apache2::AuthX::handler() deduce what has to be done (i.e. authenticate or authorise). How can handlers tell which phase they are currently in? Anthony.

You do end up paying a small overhead in forcing that determination at run time in your code, but I agree it's somewhat neater. How can handlers tell which phase they are currently in?

[ANNOUNCE] Smolder 1.21
Smolder 1.21 has just been released thanks to the Oslo Perl QA Workshop and my trip sponsored by Oslo.pm and Linpro. This releases fixes several installation bugs on various platforms and other small bugs. It also adds several new features. The highlights are: + Project categories have now been replaced by the more flexible smoke report tags + TAP archives can now be downloaded through the UI for a given report + Graphs can now be done on test run duration if that info was provided in the archive. This was inspired by Ovid's work on the BBC's test suite's run time. + The default DB-Platform is now SQLite instead of MySQL See the changle log for full details. http://sourceforge.net/projects/smolder -- Michael Peters Plus Three, LP

Hi how did you installed modperl ... static or dinamic?
