Welcome to Codidact Meta!

Codidact Meta is the meta-discussion site for the Codidact community network and the Codidact software. Whether you have bug reports or feature requests, support questions or rule discussions that touch the whole network – this is the site for you.

It is possible to close a question as duplicate to itself.


I wanted to close one of my own meta posts as duplicate, but accidentally pasted the URL to the question I was closing. The site accepted that the post got closed as duplicate to itself.

In my opinion, this shouldn't be allowed, since it doesn't make any sense.

Why should this post be closed?

I don't think this is a big problem. Presumably such errors will be rare and can be corrected easily. Adding code to prevent this human error doesn't seem like a good use of resources (coders' time or code running time).

On SE, duplicate chains mattered a lot. They used the number of duplicates to a post to determine if it was "frequent" and they used it to determine if a post could be closed/deleted etc. It doesn't seem unlikely that Codidact will come up with a similar needs in the future. Posts that are duplicates of themselves seem like an anomaly that's likely to break such algorithms in unexpected ways. Also, fixing this bug should just be a single if statement, hardly a monumental effort... Lundin‭ about 1 month ago
