This weekly summary actually encompasses the last three weeks. Sigh.

Lots of activity throughout dev is centered around the Terracotta 2.6 and 2.6.1 releases, as well as the upcoming 2.6.2 release.

Primarily I’ve been working on updating Terracotta’s Spring support to 2.5.x. Currently we only support up to 2.0.5. I had thought I had gotten it working up through Spring 2.0.8, but late last week we fixed a bug in our build process which then revealed three failing automated TC Spring tests which were previously (incorrectly) passing. So Spring 2.0.8 is not quite there…but close. Meanwhile, my compadre Nitin had made some changes that got TC working with Spring 2.5, but those changes are not backwards compatible to Spring 2.0.x, so I’m investigating whether they can be merged together somehow. Since we are dependent on the Spring source code in order to instrument their code (by using Aspectwerkz), we are subject to the whims of whatever source code changes occur between even minor releases (such as differences between Spring 2.0.5 and 2.0.8).

The other thing of note that I got accomplished was to respond to this post on our forums about a deadlock occurring in Terracotta L1. The poster had nicely laid it all out for us, with a stack trace excerpt clearly showing the deadlock. My teammates and I reviewed the pertinent class, and I cleaned up a number of synchronization bugs or missing synchronization. The deadlock itself was cleaned up by moving to a CopyOnWriteArrayList for a collection, which previously was being locked while iterating through it (read-only) and doing expensive stuff. The fix will be in 2.6.2 release.

I was without internet connection at my house a couple weeks ago for a few days. I had to do bloody battle with Charter to get that fixed. Ultimately a technician came and found that the line to my house had been put on a splitter at some undetermined point in the past, and so my signal strength was no longer strong enough. Meanwhile, luckily, I was able to go to my parents’ house and get some work done there. Have I mentioned that I love my MacBook Pro, and wireless internet?
