The problem is, I don't know what exactly triggers the problem.  It's rare -- it has only happened a few times in the last couple of months on our production server, and I can't reproduce it.  So the only test I know of is to simply install the fixed mod_webkit2 on our production server and see if the problem happens any time in the next month :-)
 
I am running the new mod_webkit2 on our test server here (which is under fairly heavy load), and if that doesn't turn up any problems I'll move it onto our production server and monitor it.

Is it possible to build a test case that exercises the proper behavior? :-)

looking over the mod_webkit code for Apache 2?


Today I was looking through the code for mod_webkit for Apache 2.X and I

found what looked like a fairly obvious bug in the

transact_with_app_server() function. I think it would possibly cause

mod_webkit to repeatedly attempt to connect with the appserver when it

wasn't supposed to. We have occasionally seen this happen on our servers,

which is why I was looking at the code in the first place.


I've fixed the code to the best of my knowledge and checked in the fix to

CVS, and tested, but I get the feeling that the code could use a 2nd pair of

eyeballs. Preferably someone who has experience with the Apache APIs,

because that's all Greek to me. I wouldn't be surprised if there were bugs

in the usage of the Apache API's because they are quite complicated.


(Note that I'm only referring to the Apache 2 mod_webkit -- Apache 1.3 uses

a totally different code base.)
