Subject [jira] Updated: (HTTPCLIENT-1001) CacheEntryUpdater does not properly update cache entry resource
Date Thu, 30 Sep 2010 15:43:33 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1001?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Michajlo Matijkiw updated HTTPCLIENT-1001:

    Attachment: cache_update_fix2.patch

This patch provides a slightly cleaner fix. 

 - Only 304 responses go through updateCacheEntry, and I have updated CacheEntryUpdater#updateCacheEntry()
to reinforce this
 - In CachingHttpClient#revalidateCacheEntry() non-304 responses go through handleBackendResponse()
to ensure cachability
 - Updated unit tests to reflect this change

I also fixed a random typo in CachedResponseSuitabilityChecker.java

Please let me know if I have missed anything.

This patch is submitted with the permission of my employer.

> CacheEntryUpdater#updateCacheEntry() copies the old cache entry's resource, though I
believe it should only do so if the response is a 304.  Otherwise it should take the response
from the server to update the entry.  This method gets called when validating a cache entry
and the server returns a 200 or 304.
