Subject [jira] [Commented] (COUCHDB-1956) Make attachment lengths and Content-Length optional for multipart requests
Date Tue, 31 Dec 2013 17:44:50 GMT


Nick North commented on COUCHDB-1956:

Happy New Year to everyone on the list. I finally have some code to improve multipart parsing,
after becoming much more familiar with the innermost intricacies than anticipated. But I haven't
yet looked into adding new tests with/without attachment length supplied and with/without
chunked encoding (though these are all tested locally). Is there any advantage in putting
the code out for review now or should it wait until the test suite is updated? If there is
any interest in seeing the code, what is the best mechanism for making it available when there
is more to be added before it's ready to merge in to the main repo?

> If you submit a document and attachments as a MIME multipart/related request, you have
to give lengths for each attachment in the initial JSON document and a Content-Length for
the HTTP request as a whole. This is inconvenient for HTTP clients which want to stream large
attachments into the HTTP request, as they may not know the attachment size in advance. 
> So CouchDb should be able to accept chunked multipart/related requests and attachments'
lengths should not have to be specified in the JSON document. These are two distinct pieces
of work but closely related, so I've put them in one issue.
> Most of the groundwork is already there in CouchDb. There is support for reading chunked
requests, but it's not currently used when parsing multipart/related requests. And attachment
lengths are not critical to parsing attachments: the parser knows by other means when it's
reached the end of an attachment, and the system internally recalculates their lengths anyway.
> Work on chunked requests is complete, but I'll save the pull request until attachment
lengths are also sorted.
