Randall Leeds commented on COUCHDB-1485:
----------------------------------------
This change actually happened with the introduction of ejson.
The COPY handler doesn't open the doc with the ejson_body option and the
revision calculation includes the body. The disk binary is used in the rev id
on the COPY destination, but the ejson body is used when the doc is first
created.
A related behavior was noticed and brought up by Kxepal. When PUT'ing
attachments to a document, the document is opened without ejson_body and so the
revision id is calculated from the binary body if the old document while the
original revision would have been calculated from the ejson parsed from the
request body on doc updates.
In both cases, parsing the document body an unnecessary operation. I will
ilkely call both of these "won't fix" if I don't hear anything for a few days,
but I'll give others a chance to weigh in.
