Emergency Upgrade to Rails 3.2.11 / Leaving ActionWebService

Today, we upgraded our Portal and back-end services which run on Rails to the latest production point release, 3.2.11. This was an emergency upgrade due to recent vulnerabilities that have been found in the product. The fixes were straightforward, but dealing with the upgrade showed us some areas where legacy code was holding us back.

We ran Rails 1.2 far longer than we should have with our old Portal, but were focused on product enhancements and features that were unrelated to the rails version. In 2012, we upgraded to 3.1, but had some old dependencies on ActionWebService. We use web service calls to communicate internally between the server running Portal and the servers running your repositories for things like modifying Subversion permissions or trac.ini files.


We were using the dnordberg fork of ActionWebService to Rails 3.x, but with the upgrade to 3.2, the port was at risk of causing issues. The methods in question were remote procedure call, and while some of them could possibly have been ported to RESTful operations, we wanted to do the minimal changes required to support the existing framework.

We ultimately did the changes in 3 steps:


  1. Modify the server-side controllers to accept parameters and return JSON instead of returning a scalar or object using render :text.
  2. Create a client with the same interface as the one defined in the API spec.
  3. Remove references to ActionWebService.


We used HTTParty to do the GETs and POSTs. To our delight, after we swapped out the transport mechanism, we found that the calls worked without further modification in most cases. Of course, fewer changes means less chance of introducing new bugs.

We’re now on 3.2 and subsequent Rails upgrades should be easier. Due to the above changes, there may still be a couple of kinks here and there, so just open a ticket if you run into a problem that gets in your way. We know that some people ran into some problems with accessing certain pages today, and we apologize for that, but due to the seriousness of the vulnerabilities, we didn’t want to wait one second more than we had to to verify the stability of the code.

Please feel free to drop us an email or reach us via ticket if you have any questions as well about what we’re doing or recommendations for improvement.

If you’re responsible for an application that depends on the data or functionality of various IoT endpoints – either sensors or devices – your brand reputation depends on the security, reliability, and compliance of its many integrated parts. If your application fails to deliver the expected business results, your customers and partners won't care if that failure stems from the code you developed or from a component that you integrated. What can you do to ensure that the endpoints work as expect...

DevOps and microservices are permeating software engineering teams broadly, whether these teams are in pure software shops but happen to run a business, such Uber and Airbnb, or in companies that rely heavily on software to run more traditional business, such as financial firms or high-end manufacturers. Microservices and DevOps have created software development and therefore business speed and agility benefits, but they have also created problems; specifically, they have created software sec...

More and more companies are looking to microservices as an architectural pattern for breaking apart applications into more manageable pieces so that agile teams can deliver new features quicker and more effectively. What this pattern has done more than anything to date is spark organizational transformations, setting the foundation for future application development. In practice, however, there are a number of considerations to make that go beyond simply “build, ship, and run,” which changes ho...
Analysis of 25,000 applications reveals 6.8% of packages/components used included known defects. Organizations standardizing on components between 2 - 3 years of age can decrease defect rates substantially. Open source and third-party packages/components live at the heart of high velocity software development organizations. Today, an average of 106 packages/components comprise 80 - 90% of a modern application, yet few organizations have visibility into what components are used where.
Throughout history, various leaders have risen up and tried to unify the world by conquest. Fortunately, none of their plans have succeeded. The world goes on just fine with each country ruling itself; no single ruler is necessary. That’s how it is with the container platform ecosystem, as well. There’s no need for one all-powerful, all-encompassing container platform. Think about any other technology sector out there – there are always multiple solutions in every space. The same goes for conta...
In this strange new world where more and more power is drawn from business technology, companies are effectively straddling two paths on the road to innovation and transformation into digital enterprises. The first path is the heritage trail – with “legacy” technology forming the background. Here, extant technologies are transformed by core IT teams to provide more API-driven approaches. Legacy systems can restrict companies that are transitioning into digital enterprises. To truly become a lea...
Let's recap what we learned from the previous chapters in the series: episode 1 and episode 2.

Now that we know what we have to restore and in which order, the question is how?
The many IoT deployments around the world are busy integrating smart devices and sensors into their enterprise IT infrastructures. Yet all of this technology – and there are an amazing number of choices – is of no use without the software to gather, communicate, and analyze the new data flows. Without software, there is no IT. In this power panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists will look at the protocols that communicate data and the emerging data analy...
