clear-cache

[jlcox]

I'm trying out the 1.6 caching for the first time, having trouble with
something that seems that it should be straightforward.

Declaration:

<property name="Caching" type="MachII.caching.CachingProperty">
<parameters>
<parameter name="defaultCacheName" value="default" />
<parameter name="default">
<struct>
<key name="type"
value="MachII.caching.strategies.TimeSpanCache" />
<key name="scope" value="application" />
<key name="timespan" value="0,1,0,0" />
<key name="cleanupIntervalInMinutes" value="3" />
</struct>
</parameter>
</parameters>
</property>

Then I cache my home page:

<event-handler event="home" access="public">
<cache alias="homePage">
<notify listener="adminListener" method="getNews"
resultArg="results"/>
<view-page name="home" contentArg="content"/>
</cache>
<execute subroutine="page.build.main"/>
</event-handler>

I hit the page several times and confirm that the cache is working by
using the groovy new Dashboard. One hit for each reload, plus a miss
for the initial load.

Now, I try to clear the cache...

<event-handler event="news.update" access="public">
<event-bean name="newsBean" type="newsBean"/>
<notify listener="adminListener" method="saveNewsItem"/>
<cache-clear alias="homePage" />
<redirect event="news"/>
</event-handler>

and I get this:


Exception
Element homePage is undefined in a CFML structure referenced as part
of an expression.

C:\Inetpub\wwwroot\MachII_1.6\framework\CacheHandler.cfc (216)
C:\Inetpub\wwwroot\MachII_1.6\framework\CacheManager.cfc (289)

How did I mess this up?

Jonah posted a work around but I think this maybe a bug. Are you running latest BER?

I think you're right. Didn't post a response - confirming.

But if you Change line 216 in CacheHandler.cfc in the clearCache
function to:

from:
<cfloop list="#variables.aliasKeyLists[currentAlias]#"
index="currentKey">
to:
<cfloop list="#variables.aliasKeyLists[hash(currentAlias)]#"
index="currentKey">

It appears to work.

I'll submit the bug.

But actually, it should probably be doing the hashing elsewhere. I
haven't studied the new caching code yet.
