This was a long standing bug with initializing the stats
collector and is now fixed in trunk
So it's only the stats collector that is not functioning
properly? Can we just use CouchDB 0.9.0 if we do not really care
about the stats collector?
This test is not failing on our testing CouchDB (also 0.9.0) by
the way. What is the explanation for that?
Hi Nils, the bug is also fixed in the 0.9.1 release candidate
being voted on now. It's a bug in the stats collector and the
test suite. The stats collector was not being reset properly on a
call to _restart, and the test suite was measuring the wrong
field. The latter bug is probably why you only saw intermittent
failures or none at all in 0.9.0.
In short, the suite was measuring the maximum rate of DBs being
opened, when it should have measured the number that were open.
So the results of the test really depended on the environment and
the hardware. Hope it helps,
Ok, so it's a bug in the test and not the 'regular' code? So we
should be fine using CouchDB 0.9.0 now?
Nils Breunese.
Yes, it's highly unlikely that particular bug has any effect on your
operation. However, keep in mind that 0.9.1 is a bugfix release and a
recommended upgrade for users of 0.9.0 when it comes out. Here's the
summary of changes:
http://svn.apache.org/viewvc/couchdb/branches/0.9.x/CHANGES?revision=786852
In particular, if you use attachments, extended Unicode, replication,
or large numbers of databases (~100 or more) I would highly recommend
upgrading. Cheers,
Adam
