Oleg Kalnichevski updated HTTPCLIENT-427:
-----------------------------------------
Attachment: HTTPCLIENT-427-immutable-cachenentry.patch
Dave, Joe
I could not fully complete the changes that I had in mind. So far I managed to
have made all variables in the CacheEntry class final which helps a great deal
to ensure thread safety of the class, but I was unable to make it truly
immutable. Variant URIs can still be mutated by multiple threads leading to a
race condition. I have also failed miserably trying to wrap my head around
EasyMock which turned out to be far from easy. One of the test cases still
fails after my changes and I was not able to fix it nor to fully understand why
it is failing in the first place. I think it is better if you take over from
here and incorporate the patch (attached) into your change set.
Cheers
Oleg
