Debugging report

I spent all day trying to get a 6.x-2 client to work with blade1.drupalfr.org. I used Ubuntu 8.04 Hardy as the OS. I tried at first to get it working with php5-xcache. It did several tests with successful RPC calls where it does both a "Test results successful sent" and "Test request successfull, received", until it tried sending after review.resetStatics(). Then it would decide to report on the client "When requesting next test, server responded: Invalid server". The master side reported "reason: Failed to install Drupal on @environment."

I did apt-get remove php5-xcache and ran it again, but the client had the debug checkbox checked. That resulted in the client and master both resporting success and enabled my client, but it turned out the drupal_checkout database's simpletest table only had 198, which meant it didn't do most of the testing.

After I disabled the debug checkbox on the client and ran without cache, it took about 2 hours to run and reported at the very end for final testing on the master side "reason: Failed on @environment, with: @pass pass, @fail fail, and @exception exception" and on the client I got "When requesting next test, server responded: Invalid server" again. There were about 11500 rows in the simpletest table.

Then I compiled APC, and ran it with apc.shm_size = 48. Really early on in the testing, I got "When requesting next test, server responded: Invalid server" on the client side again. In fact, the invalid key seems to be the only error I get on the client side no matter how I mod the configuration, it just comes up in different places. Perhaps we can improve the error message so it outputs the key that it's sending that apparently doesn't match? I'd sure like to know why exactly it's mis-matching, like maybe if there is accidental padding on the RPC string or something that gets parsed as part of the key incorrectly.

The following was how I configured the server, minus the APC and xcache parts:

This is mostly a cleaned up recounting of my .bash_history files.

As root, execute the following on commandline for a fresh install of Ubuntu 8.04 Hardy:

exit

On the client, enable CVS Deploy, PIFR, and PIFR Client modules. Then get an account on the master server. Add a client of type Test on the master and copy the key to the client at admin/pifr/configuration. The client defaults are OK. Make sure all the command line tools have output at admin/pifr/client on the client.
