Re: [infinispan-dev] Fwd: CloudCacheStore Bug
Thanks Manik,
I have a another problem with eviction, it seems to destroy cache
entries, *only
when I use async*.
Of course, all updates are transactional.
Where should I search for clues ? Any idea ?
Here is my config:
<?xml version="1.0" encoding="UTF-8"?>
<infinispan xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="urn:infinispan:config:4.0">
<global>
<transport
transportClass="org.infinispan.remoting.transport.jgroups.JGroupsTransport">
<properties>
<property name="configurationFile" value="jgroups.xml" />
</properties>
</transport>
</global>
<namedCache name="qi4j">
<transaction
transactionManagerLookupClass="org.infinispan.transaction.lookup.DummyTransactionManagerLookup"
/>
<clustering mode="distribution">
<l1 enabled="true" lifespan="100000" />
<hash numOwners="1" rehashRpcTimeout="120000" />
</clustering>
<loaders passivation="false" shared="true"
preload="false">
<loader class="org.infinispan.loaders.file.FileCacheStore"
fetchPersistentState="false" ignoreModifications="false"
purgeOnStartup="true">
<properties>
<property name="location" value="/tmp" />
</properties>
<async enabled="true" threadPoolSize="3" />
</loader>
</loaders>
<deadlockDetection enabled="true"
spinDuration="1000"></deadlockDetection>
<eviction strategy="FIFO" wakeUpInterval="1000"
maxEntries="10" />
<unsafe unreliableReturnValues="true" />
</namedCache>
</infinispan>

Ugh, good point. I thought the unit tests would have trapped a
dumb-ass
mistake like this.
The reason for transforming the name of the bucket is that we usually use
hashcodes as the bucket name, which can take Integer.MIN_VALUE to
Integer.MAX_VALUE. These are then translated into Strings, and this becomes
the name of the storage unit, e.g., 12345.bucket in the FileCacheStore. Now
filesystems are happy to accept a -12345.bucket but certain cloud storage
providers barf when encountering the '-' character. Hence the
transformation to A12345.bucket in some cases.
Cheers

PS: pushing up a new snapshot as I type, containing this fix + lower
verbosity on eviction-related lock timeouts.

Hi all,
there is a bug in CloudCacheStore that makes me feel like I am the only one
using it ;-)
in CR4 : if you change the "-" sign to "A" in getBucketName ... you
need to
do the opposite somewhere (or call it every time) ;-)
WDYT ?
