Software

When I start a new project or get setup to contribute to an existing one, the first thing on my mind is: show me the Dockerfile. Why? One of the main purposes of Docker is packaging an application with its dependencies into a portable image that can be run on most any host, thus simplifying deployments. Yet when it comes to development of these applications, Docker is often not part of the picture.

In my early days with software, I couldn’t wait to upgrade to the latest versions of everything. Service Packs, patches, major new versions. I wanted to be running the latest and greatest versions of every piece of software I could on day zero.

At my first job, our tech lead who had been at this a lot longer than me took a more conservative approach. We wouldn’t upgrade major software like our database or operating systems without at least one service release being available. We wouldn’t adopt new major versions of language platforms until there had been a service release either. I was sometimes disappointed to have to wait for the latest and greatest, but I went along with it.

More than a decade later and I’m now completely on board with this. And there’s no zealot like a convert, so here I am writing about it.

The new release adds two bits of missing functionality. Session data Data from the Session object is now added to reports. Data is described/stringified as best we can, with non-value types being reported with their type name, hash code, and .ToString() value. Param scrubbing Sensitive parameter values are now scrubbed. Each character is replaced with an asterisk. By default, any parameter in the following list will be scrubbed: password password_confirmation confirm_password secret secret_token creditcard credit_card credit_card_number card_number ccnum cc_number You can override this list by setting the Rollbar.
