I was able to work on getting Magma 1.2 going in Pharo. It was quite easy to get the code loaded and functioning in Pharo 1.1.1, Pharo 1.2, and Pharo 1.3. But something seems to have changed in Pharo's networking from 1.1.1 to 1.2. All Magma functionality seems to work fine for low-volume activity. However, when the test-suite gets to the HA test cases (at the end), one of the images performing heavy networking activity, consistently gets very slow and bogged down for some reason; causing the clients to timeout and disrupting the test suite. Fortunately, it happens in the same place in the test-suite every time. The UI of the image in question becomes VERY sluggish, but MessageTally spyAllOn: didn't reveal anything useful. What is it doing? I did verify that the Magma server in that image is still functioning; clients were committing, but I had to increase their timeouts from 10 to 45 seconds to avoid timeouts.. Unfortunately, two days of wrangling in Pharo (because I'm an old Squeak dog) I could not nail the problem down; but I have one suspect.. A couple of times, I caught a process seemingly hung up in NetworkNameResolver; trying to resolve an IP from 'localhost'. This exact set of Magma packages is rock-solid on Pharo 1.1.1 and Squeak, but that doesn't mean the problem for sure lies in Pharo 1.2; maybe a networking bug in 1.1.1 is allowing Magma to "misuse" the network and get away with it and Pharo 1.2 is now more strict? I don't know, I would just like to ask the experts here for help who know all what went into Pharo 1.2 so hopefully we can get to the bottom of it. Thanks, Chris
