Editor's Notes
- #2: Welcome to “Squashing Bugs with the Apex Debugger". My name is Vivek M. Chawla and I'm here today with my colleague Danny Chang. As the title says, we're going to be talking about the Apex Debugger today. So, if you're curious about the debugger but haven't yet had a chance to learn about it or see it in action, then you’re in the right place!
- #3: Danny and I are both ISV Technical Evangelists here at Salesforce. Within our team, he and I cover Apex as one of our areas of technical specialization, which is why we wanted to come here today to talk with you about the Apex Debugger. As you can see, we’re both on Twitter. If you have any questions after today’s session, please don’t be shy about reaching out to us. We’re happy to help.
- #4: In this session, we’re going to give a quick overview of... What the Apex Debugger is How to get setup and start a debugging session Hands on demo how to use the debugger to find and squash a tricky bug Special Considerations, Roadmap, and Q&A
- #5: OK, just about ready to get started. Before we do, one last thing. Our good-old “Forward Looking Statements” slide....
- #6: So, first things first. What is the Apex Debugger?
- #7: The Apex Debugger is an interactive debugger. An interactive debugger comes with some nice advantages, like... Breakpoints: The ability to choose places in your code where you’d like to STOP program execution in order to inspect the current state within your application logic Single-Step Execution: The ability to step line by line through your code, executing your logic bit-by-bit View Variables & Call Stack: The ability to see in real time what values are being assigned to your variables in both the current call and any other calls on the stack So, this is pretty cool stuff, but you might be wondering how any of this is better than using debug logs. After all, debug logs are free while the Apex Debugger can carry an additional cost...
- #8: Well, I look at it like this. Using the Debug Logs is a lot like doing an autopsy. You can learn a lot about everything that just happened, but it’s a 100% post-mortem exercise. On the other hand, using an interactive debugger is like getting an MRI. You can see what’s going on inside the body at a very detailed level, all while the subject is still breathing. This brings me to one of my first specific points about the Apex Debugger. The ability to pause execution to get this real-time, living, breathing, inside look at your code is why we only allow debug sessions against sandbox orgs. Look at it this way: You wouldn’t want someone holding a database connection open for 20 minutes on a production pod because a co-worker dropped by to chat while they were in the middle of debugging. Now that we’ve talked about the value of interactive debugging in general, lets learn more about the Apex Debugger in particular.
- #9: At a high level, there are two flavors of the Apex Debugger. A standard version that’s used by Salesforce customers to debug code in orgs that they own An ISV version that’s used by Partners to debug code in orgs that their customers own In either case, the debugger is only available in Enterprise, Unlimited, and Performance Edition orgs Let’s look at the standard version first For CUSTOMERS who want to use the debugger, the first thing to do is make sure you have a license for at least ONE debugging session assigned to your production org Unlimited and Performance Edition orgs each include a license for one session, but Enterprise Edition orgs don’t. For EE orgs, using the debugger will require an add-on purchase As I mentioned on the previous slide, the debugger can only be used with sandbox orgs Each debugger license allows one active debugging session to be initiated with any sandbox created by the production org. As a developer, I decide which sandbox I need to work in, create a project in Eclipse, and initiate a debugging session When I do that, my license count drops by one. If anyone else on my team wants to use the debugger, they’ll have to wait until I terminate my session. For ISV Partners, things are a bit different ISVs don’t have direct login access to customer orgs. They have to use the Subscriber Console in their License Management Org for access. This means that the license for the ISV Debugger has to go in the License Management Org The ISV Developer logs into the LMO and uses the Subscriber Console to connect to a customer sandbox where the ISVs package has been installed. Once the debugging session starts, the license count drops by one and you’ve got the same situation as the standard debugger. If anyone else wants to use the debugger, they’ll have to wait until my session is terminated. This was a high level look at the two flavors and how they work. Now let's get a little more specific.
