couchdb.http.PreconditionFailed: ('missing_stub', ...)

[Mikhail Sobolev <mi...@gmail.com>]

Hi,

I just upgraded to couchdb 0.11 and my application fails with
    couchdb.http.PreconditionFailed: ('missing_stub', ...)

What could lead to such an error?

OK, I played a bit with the code I sent previous (fap.py) and it
turned out that the following change is done:
-        doc['_attachments'][filename] = dict(stub=True, revpos=doc.rev)
+        doc['_attachments'][filename] = dict(stub=True,
revpos=int(doc.rev.split('-')[0]))

everything starts to work as it used to without revpos.

PS  The main reason why I did the code like this is because I did not
want to download the whole document every time any of its attachments
are downloaded.

The funny thing is that the code that throws the exception
(src/couchdb/couch_doc.erl:364) was written in November last year...

This idea crossed my mind :)

Essentially, I'm doing the following:

1. create a document with props
2. save it
3. add an attanchment
4. update some document props related to the attachment
5. save the updated document

3-5 are repeated several times.

At 3 & 5, the _rev is updated properly.  At 3 with the previous
version of couchdb (0.10.1) a simple 'trick" of adding/updating
_attachment ("filename": { "stub": true}) was working just fine.  With
the new version it bails out with the message in the subject.  The
attached file shows what I'm I doing the 'head' of couchdb-python
module.  (The previous version did not have 'revpos=doc.rev'.)

The code used to work.

Some code :D — What are you trying to do? :)

My bet is on you try updating or deleting a document without passing in a valid _rev.
