Ensure Controller actions/classes have authorisation

A couple of years ago I wrote a unit test to ensure that all our controller actions (or Controller classes) had appropriate authorisation set up. This ensures we don’t go to production with a new controller or action that falls back to the default authorisation. We must think about this and explicitly apply it. I’ve […]

Creating a Throttle with an ActionBlock – Addendum (Cancelling)

In my previous post I described how to create a throttle with an action block so you wouldn’t have too many tasks running simultaneously. But what if you want to cancel the tasks? In our use case, we have a hard-limit of 2 minutes to complete the work (or as much as possible). A typical […]

Creating a Throttle with ActionBlock

We have an application that needs to perform a repetitive task on many external services and record then aggregate the results. As the system has grown the number of external systems has increased which causes some issues as we originally just created a number of tasks and waited on them all completing. This overwhelmed various […]

Comparing logically adjacent rows in a database table

If you have database table that stores something such as when an action occurred, it might be useful to work out how far apart these events are. It is easy to join different tables together, or even if you have a self-referential join to join rows of the same table together if an existing relationship […]

Paramore Brighter: The Russian Doll Model

I’ve mentioned a bit about the attributing the handler and the step and timing parameters, but I’ve not explained them properly in previous posts (“Retrying commands” mentions steps, and “Don’t Repeat Yourself” also mentions timings). So, I’ve created a small project to demonstrate what they mean and how it all operates. The code for this […]

Paramore Brighter: DRY with Custom Decorated Command Handlers

You may wish to add similar functionality to many (or all) command handlers. The typical example is logging. You can decorate a command handler in a similar way to the policies I showed in previous posts to add common functionality. I’ve used this technique to guard the handler from invalid command arguments/parameters (essentially a validator), […]

Paramore Brighter with Quality of Service: Retrying Commands

Paramore Brighter supports Policies to maintain quality of service. This is useful when your command makes calls to external services, whether they are databases, web services, or any other end point that exists out of the process of your application. You can set up retry policies, circuit-breaker policies, and timeout policies. For this post, we’ll […]

Setting file permissions on a remote machine with PowerShell

Recently I needed to set some file permissions on a remote machine. Previously I’d done this relatively easily through a share as the user account I was using also had administrator rights on the other side and I was dealing with domain accounts. However, this did not work for a user that was local to […]

IIS Administration file access

If you are using the IIS Administration ReST API to manage IIS, one thing that is not immediately obvious is that if you put your websites outside of %systemdrive%\inetpub you won’t be able to access them through the API. e.g. You won’t be able to set the physical path of a website to a location […]

Taking ownership of a file

I’m currently looking at using IIS Administration as a way to automate some deployment tasks. However, the way it got installed, it’s appsettings.json file could not be written to, even when running the text editor as Administrator. It turns out, SYSTEM had full control of the file, and the installer configured it to only allow […]
