Eclipse/App Engine/Bloog Part 4, The hard part

Well I had a long and frustrating week/week-end, all sort of run together. I discovered that my new site would not take even moderately long articles. This is apparently a “known problem” and it relates to exploding indexes, as somewhat explained here.

I finally got to corresponding with one of the Bloog Maintainers who had it turned out created a modified site search capability using Google Site Search. According to him  it still does not provide for longer article without some code mods that I have not yet started. But is a prerequisite. I got a copy from Git-hub, where Bloog is hosted. This required that I get and install GIT version control system. I chose to start with Windows based  Git Extensions. It still required that you install the basic GIT. It is only available in Tar format you will need 7zip to unpack although after a posting the developer has now provided a “full” option for Git extensions.

I then tried to apply the new code to my existing Bloog version as I had modified it. That required a differential editor,which I did not have Kdiff3 turned out to be a great choice. It compares entire directory structures and than lets you click through the files and selectively choose to apply a, b to your revised file. Very cool.

I then tried to fire things up, FAIL. I then went back to the Version I had just obtained and I could not get it to fire up either. I then started to look for “real” debug information. Not much available.

Eventually I downloaded PYdev for Eclipse, and that was a major improvement  my entire development environment. In fact I would go so far to say Do not attempt development for APP-Engine without Pydev!! It provides a much better editor, code outlining and a runtime environment. There are several tutorials on setting up Eclipse for app-engine. Use them!!! Supposedly it also provides breakpoints, but I have not been able to get that working yet, but the other improvements are a major joy. The Debug environment did give me better log messages. Through which I was eventually able to make some headway. I found out that the two versions had changed the DB schema slightly so I had to delete a few older records You can see and modify the local datastore using http://localhost:8080/_ah/admin/datastore and bang it all started to work. It actually took a long time to go through each step, and I still have to go back and learn each of the new tools much better.
