[GitHub] [couchdb] nicolas-albert opened a new issue #3328: Incorrect multipart/related response in case of _bulk_get with attachments and atts_since

[GitBox <gi...@apache.org>]

nicolas-albert opened a new issue #3328:
URL: https://github.com/apache/couchdb/issues/3328


   ## Description
   
   The _bulk_get service allows to retrieve multiple documents with their attachments. If the client already have a revision of a document, the atts_since option allows to not reply an unmodified attachment again.
   
   In this case, the part is incorrect:
   ```
   ----68dd74e8c5bb2822e23a8ada6eeb2619
   X-Doc-Id: att_10
   X-Rev-Id: 3-a50b011b678507001e15d904295bccf1
   Content-Type: multipart/related; boundary=--c994d3e17aee82de2d947e57171e97ad
   
   {"_id":"att_10","_rev":"3-a50b011b678507001e15d904295bccf1","data":"data_10","_revisions":{"start":3,"ids":["a50b011b678507001e15d904295bccf1","3d2ba9b990fa62a3aeabc75f86aaace8","167072636fface8c96ec4eb1cb915814"]},"_attachments":{"text.txt":{"content_type":"text/plain","revpos":2,"digest":"md5-VviK0JqDf+w9vDhCLZSI5Q==","length":11,"stub":true,"encoding":"gzip","encoded_length":31}}}
   ----68dd74e8c5bb2822e23a8ada6eeb2619
   ```
   The part declares a sub multipart/related with a boundary never used and the application/json Content-Type isn't set.
   The couchbaselite-java (1.4.x) library break the replication because of this nonsense.
   
   ## Steps to Reproduce
   
   Take a document with an attachment, note its revision and make a new revision:
   `curl -H "Accept: multipart/related" -H "Content-Type: application/json" -d '{"docs":[{"atts_since":["x-oldrev"],"rev":"y-newrev","id":"mydoc"}]}' "http://localhost:5984/mydb/_bulk_get?revs=true&attachments=true"`
   
   Should also works with multiple docs for the same query.
   
   ## Expected Behaviour
   
   Instead, we should have something like this:
   ```
   ----68dd74e8c5bb2822e23a8ada6eeb2619
   X-Doc-Id: att_10
   X-Rev-Id: 3-a50b011b678507001e15d904295bccf1
   Content-Type: multipart/related; boundary=--c994d3e17aee82de2d947e57171e97ad
   
   ----c994d3e17aee82de2d947e57171e97ad
   Content-Type: application/json
   
   {"_id":"att_10","_rev":"3-a50b011b678507001e15d904295bccf1","data":"data_10","_revisions":{"start":3,"ids":["a50b011b678507001e15d904295bccf1","3d2ba9b990fa62a3aeabc75f86aaace8","167072636fface8c96ec4eb1cb915814"]},"_attachments":{"text.txt":{"content_type":"text/plain","revpos":2,"digest":"md5-VviK0JqDf+w9vDhCLZSI5Q==","length":11,"stub":true,"encoding":"gzip","encoded_length":31}}}
   ----c994d3e17aee82de2d947e57171e97ad--
   ----68dd74e8c5bb2822e23a8ada6eeb2619
   ```
