Subject [jira] [Commented] (COUCHDB-1415) Re-insering a document silently fails after compact is executed
Date Tue, 08 Oct 2013 14:02:43 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1415?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13789225#comment-13789225
] 

Dave Cottlehuber commented on COUCHDB-1415:
-------------------------------------------

[~eric ross] thanks that would be appreciated. https://github.com/apache/couchdb/blob/master/share/doc/src/contributing.rst
has notes on how to do this, feel free to ask any questions. An attached patch is also fine
if you are not yet a git user.

Both yourself and [~lancecarlson], does this bug come up in *real_world* usage? I'm trying
to imagine a situation where I add & delete the same content furiously in practice, and
I can't think of one that actually makes sense (i.e. fits with the grain of couchdb). I'd
either use redis for this type of frequent state changing transaction, or consider using something
that preserves the transaction history.

>             Project: CouchDB
>          Issue Type: Bug
>          Components: Database Core
>    Affects Versions: 1.1.1
>         Environment: Tested on multiple linux platforms
>            Reporter: Viktor Szabo

> When a document is re-inserted after a compact operation using the same contents it was
originally created, the insert operation is silently ignored, leaving the client unaware of
the fact it's document is not available in the database.
> Can be reproduced using the following sequence of steps:
> alias curl='curl -H "Content-Type: application/json"'
> url="http://localhost:5984/database"
> 1 curl -X PUT $url
> 2 curl -X POST $url -d '{"_id": "bug", "key": "value"}'
> 3 curl -X DELETE "$url/bug?rev=1-59414e77c768bc202142ac82c2f129de"
> 4 curl -X POST "$url/_compact"
> 5 curl -X POST $url -d '{"_id": "bug", "key": "value"}'
> 6 curl -X GET "$url/bug"
>   (bug here)
> 1 {"ok":true}
>   201
> 2 [{"ok":true,"id":"bug","rev":"1-59414e77c768bc202142ac82c2f129de"}]
>   201
> 3 {"ok":true,"id":"bug","rev":"2-9b2e3bcc3752a3a952a3570b2ed4d27e"}
>   200
> 4 {"ok":true}
>   202
> 5 [{"ok":true,"id":"bug","rev":"1-59414e77c768bc202142ac82c2f129de"}]
>   201
> 6 {"error":"not_found","reason":"deleted"}
>   404
> CouchDB shouldn't report "ok" on step 5 and then go on to claim that the doc is deleted.
Also, it seems to work on second try:
> 7 curl -X POST $url -d '{"_id": "bug", "key": "value"}'
> 8 curl -X GET "$url/bug"
> 7 {"ok":true,"id":"bug","rev":"3-674f864b73df1c80925e48436e21d550"}
>   201
> 8 {"_id":"bug","_rev":"3-674f864b73df1c80925e48436e21d550","key":"value"}
>   200
