Subject [jira] Commented: (COUCHDB-1020) 202 status on "DELETE /db"
Date Sun, 09 Jan 2011 22:58:46 GMT


Benoit Chesneau commented on COUCHDB-1020:

afaik I think lotus domino has pending delete database feature. Until file isn't deleted it
is pending. I reckon it works differently. You mark a file to be deleted than check it to
finally delete file.

My idea is to consider a DB /delete as a way to mark the db as deleted (reference is removed)
but saying file deletion is pending which could be considered as a 202 status response on
delete. I can live with a 200, but this detail may be interesting for reporting and monitoring.

tthat sicne db isn't accessible from HTTP api, 200 is ok.

The request might or might not eventually be acted upon, as it might be disallowed when processing
actually takes place. There is no facility for re-sending a status code from an asynchronous
operation such as this.
> The 202 response is intentionally non-committal. Its purpose is to allow a server to
accept a request for some other process (perhaps a batch-oriented process that is only run
once per day) without requiring that the user agent's connection to the server persist until
the process is completed. The entity returned with this response SHOULD include an indication
of the request's current status and either a pointer to a status monitor or some estimate
of when the user can expect the request to be fulfilled.

> Since it's true that deletion introduce an aysnchronous process to delete the db file
an it's data, I think that 202 is more appropriate here.
> 202 would mean, that resource isn't available but deletion is running. Related to #COUCHDB-1019
we could pass a pid or taskid to the response eventually.
