Subject [jira] [Commented] (COUCHDB-1797) Query against a view w/ include_docs=true yields doc:null
Date Fri, 08 Nov 2013 14:01:19 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1797?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13817292#comment-13817292
] 

Benoit Chesneau commented on COUCHDB-1797:
------------------------------------------

It looks a lot like a bug I have with the view changes sometimes which was solved here:

https://github.com/refuge/couch_core/commit/58bc6a23ae54f4e614638a76fd412bee7dac5c83#diff-989c52b9ea42136621dd01fbe8f7044fR548

(still in a test branch) . Imo somewhere we forget to refresh the btree state and the information
about new leafs is missing.

>             Project: CouchDB
>          Issue Type: Bug
>          Components: Database Core
>    Affects Versions: 1.3
>            Reporter: Marten Feldtmann
>            Priority: Critical

> I have a test system (CouchDB 1.3.0 under windows 7/64 Bit), where I insert lots of documents(100000)
to get a regular flow of new incoming documents.
> The database has also some views (25). Another task is reading documents from a view,
change some attributes and then the document should disappear from the view (and appear in
another view). Something like a state machine.
> I do the following query against a view:
> http://localhost:5984/test5/_design/ticketorggraphics/_view/waiting?limit=5&include_docs=true&include_end=true
> and get the following string:
> {"total_rows":9224,"offset":0,"rows":[

> Please notice, that the doc attribute of the third item in the rows attribute has the
value "null". That means, that the view entry has no belonging document ????????
> This seems to indicate an inconsistency within the database.
> I can not say, when this error happens, but I know, that it will happen in my test run.
