In THIS article, the following is stated:

The Publish process and the Transport process can both be extended using the IPublishTransactionHandler and ITransportPackageItemHandler interfaces respectively.

My question is, are these extension points still available in 8 or 8.5 (the official docs only mention custom resolvers and custom renderers)? If yes, where can I find these interfaces and where should they be plugged into?

Looking at the 2011 chm files, I am unable to find them. In SDL Tridion 2011 Content Delivery ASP.NET API there is a Com.Tridion.Distribution.Transport.Transaction namespace which sounds promising, but looking at the members I can't find anything useful. Nor do I see the interfaces in any of the 8.5 API-s.

Any ideas?

Mentioned extension points are “semi-public” CM Publisher extension points.

This means that these are technically speaking public APIs, but they are intentionally kept a bit under the radar, because they are considered “advanced” customizations (not expected to be needed for typical use cases).

So, the question for you is: which use cases do you have in mind that might require those extension points?

  • Yeah it's a very atypical use case indeed, unfortunately I am not permitted to disclose it at this point. Btw. I managed to find the interfaces and where to plug them, but for the sake of keeping them under the radar I won't document them here.
