Yes, since nnimap doesn't support `nnchoke-request-move-article' (it is impossible to implement in IMAP) Gnus does retrieve+delete instead, and the delete code move things into the expiry-target.

Couldn't nnimap just do the retrieve+delete within -request-move-article? That's pretty much what other backends do, right? paul ^ permalink raw reply [flat|nested] 14+ messages in thread

Um, yes, now that I look at it, this is how it is done. :-) I was thinking of `nnchoke-request-replace-article'... Then I wonder why this happens. Ah, yes -- if you move an article from a nnimap group to a nnfolder group (which was the case in this thread), moving doesn't happen within one backend, so Gnus does retrieve+delete. And nnimap can't know this case from the case where articles are simply expired. Neither could nnml or nnfolder, so I guess this is a generic problem. ^ permalink raw reply [flat|nested] 14+ messages in thread

I thought gnus-summary-move-article calls gnus-request-move-article which calls nnchoke-request-move-article? And nnchoke-request-move-article is supposed to call nnbloke-request-accept-article for the target server/group. Or did I miss something in the code? kai -- Abort this operation?

Why doesn't Gnus just put nnfolder-request-accept article into the form it passes to nnimap-request-move-article?

You are right, I was hallucinating -- it was a bug in nnimap. Moving articles from nnimap groups shouldn't place a copy in the expiry-target now.

Thinking more on this - even if Gnus does retrieve+delete, it could (and ought to) use nnchoke-request-move-article to do it. Using nnchoke-request-article is wrong, since it doesn't undo any changes made by the backend, and using nnchoke-request-expire-articles is wrong as has already been mentioned. To retrieve with n-r-m-a, just pass nil as the accept-form; the article will then be in the given buffer. To delete with n-r-m-a, pass t as the accept-form. (Passing the destination backend's -request-accept article would be even better, but might be a harder change to make.) paul ^ permalink raw reply [flat|nested] 14+ messages in thread
