AppEngine Rolling back failed AppEngine deploys in Hudson In a previous post I mentioned how to set up a build that deployed to AppEngine using Hudson. I’ve been using such a build for a while for JS-Analytics but its frustrating when the deploy operation fails midway. When this happens you need to issue a Rollback command at
AppEngine Setting up CI on Hudson for Python based AppEngine apps This post describes how I for JS-Analytics use a Hudson build server for Continues Integration, publishing to Google AppEngine on successful builds. The build currently does just two things: It runs all my unit-tests and calculate code coverage on them. This step is to ensure that the application isn’t
AppEngine Testing on Google AppEngine (Python SDK) Testing in Python and Django is pretty straight forward. However I wanted to write tests that assert email sending, URL fetching and other external sources. Making sure the intended code is executed and allowing me to write fuller tests.

AppEngine Grails vs. Python on Google AppEngine A few weeks ago I got fed up with the bad performance I was getting on Google AppEngine for my Grails project.

AppEngine Hudson build server + Grails + AppEngine I just set up a build server for my Grails project. I chose Hudson since it was the one mentioned to work well, and it did. I’m quite happy with Hudson thus far. It hasn’t crashed (actually it crashed my browser once, more on that later), and been
AppEngine AppEngine + Grails + Cron I just added a Cron job to “ping” my application every 1 minute. After a short discussion with Paul Cusch, whom commented on one of my previous posts regarding the load request issues Grails on AppEngine is seeing. I decided to give it a try. This solution is entirely based
AppEngine Added precompilation-enabled to AppEngine plugin In the 1.2.8 version of the AppEngine SDK there is an option to precompile your solution as you deploy it to the AppEngine.

AppEngine AppEngine startup performance attack plan revealed Google just announced their attack plan for handling the long startup cost for, among others, Grails applications.

AppEngine AppEngine start up cost I’m struggling with an issue where Google AppEngine will take over 30 seconds to do the initial loading of my hosted web-application.

AppEngine Google AppEngine and Grails 1.2-M2 I upgraded this morning, figuring that the changes related to the .gsp views and their pre-compiling would reduce the cold start issues I’m having with Google AppEngine.

AppEngine Finding entities with GORM-JPA I’ve been having this issue for a while. Putting it off, but now I had to get my hands dirty. The findBy… methods weren’t returning any objects even though there were data fitting the specified values. So tonight I finally took the time to take a look at
