Brian Candler commented on COUCHDB-642:
---------------------------------------
I'd prefer that the rev in the URL overrode any value in the document, because:
(1) This is what happens for _id. That is, I believe that any _id within the
document is ignored in a PUT, in favour of the id in the URL.
(2) I think it's more "relaxed" if I can specify the _id and _rev in the URL,
then I can forget about what's in the document. If I were forced to erase the
value in the document, or make it equal to what's in the URL, then I'd just put
it in the document in the first place.

> A DELETE request lets you append ?rev=xxxx to the URL. But this doesn't work
> with a PUT request; you have to put the _rev in the body instead (even though
> the _id is taken from the URL path)
> $ curl -X PUT -d "{}"
> http://brianadmin:[email protected]:5984/briantest/foo
> {"ok":true,"id":"foo","rev":"1-967a00dff5e02add41819138abb3284d"}
> $ curl -X PUT -d "{}"
> http://brianadmin:[email protected]:5984/briantest/foo?rev=1-967a00dff5e02add41819138abb3284d
> {"error":"conflict","reason":"Document update conflict."}
> $ curl -X PUT -d '{"_rev":"1-967a00dff5e02add41819138abb3284d"}'
> http://brianadmin:[email protected]:5984/briantest/foo
> {"ok":true,"id":"foo","rev":"2-7051cbe5c8faecd085a3fa619e6e6337"}
> Allowing ?rev in the URL would make PUT and DELETE more consistent, and would
> allow you to replace an existing JSON doc with another one without having to
> merge the _rev into it first.
