Running code analysis through Sonar Cloud in Azure DevOps

Sonar Cloud is the SaaS version of SonarQube, a static code analyzer. It can inspect your code against a set of quality standards, detect bugs, security vulnerabilities,  calculate technical debt and see how your code quality evolves over time.

If you want to use it in Azure DevOps you should first install the SonarCloud extension from the marketplace: https://marketplace.visualstudio.com/items?itemName=SonarSource.sonarcloud

After the extension is installed you get 3 new build tasks:

Remark: Notice that this are not the same build tasks as should be used when using SonarQube(!)

Let’s create a build pipeline that uses these tasks:

  • First add the Prepare analysis on SonarCloud task. This task should be added to the beginning of your pipeline.  In this task you should configure the SonarCloud Service Endpoint, specify an Organization and set a Project Key and Project Name.
    • This information will be used to create a new project inside SonarCloud.
    • A last important step inside this task is to select the way analysis should be done. As we are building a .NET core application, we can set this to ‘Integrate with MSBuild’:

  • Next we should add the Run Code Analysis task. This task should be executed after our code has been build and all tests are executed.
  • At the end of the pipeline we can add the Publish Quality Gate Results step to upload the data to SonarCloud.

Our full pipeline now looks like this:

A last tip; I would recommended to not configure this on every CI build as it makes your build time a lot longer.

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cache stampede: when our cache turned against us

While investigating some performance issues, we ran into an ASP.NET Core API that cached a fairly expensive aggregation query for 60 seconds. Under normal load, that was fine: one request rebuilds the cache, everyone else reads from it. Under peak load, dozens of requests would arrive in that same expiry window, all see a cache miss, and all fire the same expensive query in parallel. The database didn't like that. That was the moment when our caching layer stopped helping and started hurting. A burst of requests comes in at the same time, all miss the cache, and all go hammer the database or the downstream API at once. That's a cache stampede . The cache was supposed to protect our backend, and for a few hundred milliseconds it did the opposite. Why this happens IMemoryCache.GetOrCreate (and its async sibling) looks like it protects you, but it doesn't add any locking on its own. Look at the naive version: public async Task<Report> GetReportAsync(string key) ...

A complex system designed from scratch never works

A few years ago, I worked as an architect on a big mainframe rewrite. I still count it as one of my failures. Not because the technology was wrong, but because I couldn't convince the management team to simplify the approach. Years later, the organization is still struggling to get the new system up and running. I left the project at the time, because I couldn't put my name behind an approach that would take very long and cost a lot of money without a working system to show for it along the way. Gall’s Law That memory keeps coming back to me, because it's a textbook case of Gall's Law playing out in real life. Gall's Law , from John Gall's Systemantics , states it plainly: A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works, and it cannot be patched to make it work. You have to start over with a simple system that works. What does that mean in practice,...
