Team Foundation Server WorkItem FieldControl Attributes

Probably the easiest way to customize a TFS WorkItem is by using the Process editor, a part of the TFS Power Tools. Using this editor you can add your own work item fields, customize the layout and change the corresponding workflow. Next to the obvious list of settings there are some less known things you can change using the Attributes property.

By using these attributes you can add custom attributes to the Work Item XML. Here are some useful attribute samples:

  • NumberFormat (for FieldControl only): Useful if a number value is displayed in the field. Possible values: WholeNumbers, SignedWholeNumbers, DecimalNumbers, SignedDecimalNumbers. Setting this attribute determines what characters are allowed to be entered in this control.
  • MaxLength (for FieldControl only): Maximum length of allowed characters for field control in form UI.
  • Format (for DateTimeControl only): One of values of DateTimePickerFormat enum. Possible values: Long, Short, Time and Custom. Custom format can be set by having 'Custom' as value for this attribute, and setting another attribute named CustomFormat with actual custom format string.

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) ...
