SonarQube–Error after updating the Prepare Analysis Task in Azure DevOps

I noticed when running a pipeline in Azure DevOps that I got some warnings on the SonarQube related tasks. It complained that I should update to a newer version. So I thought why not and updated the related tasks to the latest version (7.* at the moment of writing this post).

However when I tried to run the pipeline again afterwards it no longer worked and failed on the Prepare Analysis Task:

Starting: Prepare analysis on SonarQube

==============================================================================

Task : Prepare Analysis Configuration

Description : Prepare SonarQube Server analysis configuration

Version : 7.1.1

##[error][ERROR] SonarQube Server: Error while executing task Prepare: Use 'scannerMode: dotnet' instead of 'scannerMode: MSBuild' in your task configuration.

##[error]Use 'scannerMode: dotnet' instead of 'scannerMode: MSBuild' in your task configuration.

Finishing: Prepare analysis on SonarQube

Turned out that I was a little bit too fast. After changing the tasks to the latest version I also had to explicitly select the way to run the analysis in the Prepare task:

 


After (re)checking the radiobutton and saving the pipeline, the error disappeared.

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) ...

Azure DevOps/ GitHub emoji

I’m really bad at remembering emoji’s. So here is cheat sheet with all emoji’s that can be used in tools that support the github emoji markdown markup: All credits go to rcaviers who created this list.
