Alexander Shorin closed COUCHDB-2700.
-------------------------------------
Resolution: Not A Problem
The only place where this error may be raised in
[/db/_bulk_docs|https://github.com/apache/couchdb/blob/1.6.1/src/couchdb/couch_httpd_db.erl#L294-L295]
endpoint which doesn't supports multipart requests.
> multipart/related parsing broken when attachment contents change

> Key: COUCHDB-2700
> URL: https://issues.apache.org/jira/browse/COUCHDB-2700
> Project: CouchDB
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: Database Core
> Reporter: Nolan Lawson
>
> I can reliably reproduce a bug whereby CouchDB 1.6.1 throws this error:
> {code:javascript}
> {"status":400,"name":"content_md5_mismatch","message":"Missing JSON list of
> 'docs'"}
> {code}
> Unfortunately this is a really complicated test case, so it's prohibitively
> time-consuming for me to turn it into a set of CURL requests. Instead I've
> made a branch in the PouchDB codebase to reproduce this.
> Steps:
> {code}
> git clone https://github.com/pouchdb/pouchdb.git --depth 1 --branch
> 3871-repro-for-couchdb
> cd pouchdb
> npm install
> npm run dev
> {code}
> Once the dev server is running (takes a few seconds to start), open the
> following URL in Chrome:
> {code}
> http://localhost:8000/tests/integration/?grep=test.attachments.js-%20local%3Ahttp%20replication%20with%20changing%20attachments
> {code}
> The tests assume that you have a CouchDB running in admin party mode at
> {{localhost:5984}}. If that's not the case, you can set the CouchDB host like
> {{COUCH_HOST=http://path/to/couch:5984 npm run dev}}.
> You can see the PouchDB unit test itself [here |
> https://github.com/pouchdb/pouchdb/blob/3871-repro-for-couchdb/tests/integration/test.attachments.js#L2215-L2267].
> It basically replicates a document between two databases several times,
> while changing the contents of the attachment (but keeping the attachment
> filename). Note that this test passes against PouchDB Server, where we are
> using [node-multiparty | https://www.npmjs.com/package/multiparty] for
> multipart parsing.
> In case it helps, I suspect the multipart parsing issue may also be related
> to a point [~isaacs] raised [in the npm fullfat repo |
> https://github.com/npm/npm-fullfat-registry/blob/2305c019740a7fd2f60fa1622842d6522a721b77/fullfat.js#L388-L390].
> Please also give me any insights into how to write a workaround for CouchDB
> 1.6, because I would still like to implement multipart support for older
> versions of CouchDB.
