[jira] Created: (COUCHDB-133) Strange "random" error in view update
Strange "random" error in view update
-------------------------------------
Key: COUCHDB-133
URL: https://issues.apache.org/jira/browse/COUCHDB-133
Project: CouchDB
Issue Type: Bug
Components: Database Core
Affects Versions: 0.9
Environment: Linux 2.6.26-gentoo-r1 #3 PREEMPT
Reporter: Kore Nordmann
Never experiencing this when running an application normally, but when I run a test suite, which of course executes lots of queries in a quite short time frame. The error I get back from CouchDB (revision 700854) is:
> Error (500) in request: error ({{nocatch,{error,eacces}},[{couch_view,start_update_loop,4}]}).
This does not always seem to happen in the same test case, and after that error I can't connect to CouchDB for a short tim espan anymore (less then a second), but it comes back most times.
Some times CouchDB stops responding completely until it is restarted after that error.
A request causing this for example looks like:
> GET /arbit_test/_view/users/user?key=null HTTP/1.1
> Host: localhost
> Connection: Keep-Alive
> HTTP/1.1 500 Internal Server Error
> Server: CouchDB/0.9.0a694945-incubating (Erlang OTP/R12B)
> Date: Wed, 01 Oct 2008 18:27:33 GMT
> Content-Type: text/plain;charset=utf-8
> Content-Length: 90
> Cache-Control: must-revalidate
>
> {"error":"error","reason":"{{nocatch,{error,eacces}},[{couch_view,start_update_loop,4}]}"}
The full HTTP log of a test run and the corresponding couch.log with log level=debug can be found here:
http://k023.de/http.log
http://k023.de/couch.log
I hope this helps debugging this issue. If you need more information you may contact me on IRC (timezone: GMT; nick: koredn) in the CouchDB channel.
If you want to run the test suite yourself, to reproduce the failures, you'd need PHP 5.3 (sic!) and the latest version of PHPUnit[1] installed. Then you can just do so, by executing:
> svn co svn://arbitracker.org/arbit/trunk arbit ; cd arbit
> ./runTests controller
Kind regards,
Kore

Kore Nordmann commented on COUCHDB-133:
---------------------------------------
Thanks for the help, that worked. One single view definition file really was owned by a different user.

[jira] Resolved: (COUCHDB-133) Strange "random" error in view
update
Posted by "Damien Katz (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/COUCHDB-133?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Damien Katz resolved COUCHDB-133.
---------------------------------
Resolution: Invalid
Assignee: Damien Katz
This appears to be a case of CouchDB trying to open index files that were created by a different user. The pauses are because Erlang is restarting CouchDB components in an attempt to recover after the file open failures.
Try deleting the index file to the test databases ("rm -rf .test_suite_db*_design" in the database dir) and restart couchdb.
