A regression was introduced with commit:

    cooker/command: Add finishcommand to reset cooker state
    
    After running a command on the server, it needs to reset to the initial
    state. This ensures that subsequent clients start from a known state
    and notice any configuration changes.
    
    Ultimately we may want to do more than this buts a good start and better
    than nothing.
===

The test is to run an operation twice where we expect that the cache should not reload or that the reload operation is extremely fast, vs a full cache reload. 

. oe-init-build-env-memres
bitbake -c patch bash
# Now there should be no cache reload on the second try
bitbake -c patch bash

patch sent to bitbake ml
Comment 2 Cristiana Voicu 2014-03-26 08:06:53 UTC 
Removed 5535 from depends, because after investigation I found that there is a different issue. For #5535, the server should always be reseted, but for the current issue a sanity check for the cache is needed.
Comment 3 Alexandru Damian 2014-03-28 11:40:31 UTC 
IMHO, this is not a bug, but an expected behaviour, see bug 5535.
My point is that bug 5535 is in direct conflict with this bug, and 

I would expect a cooker reset and a full cache reload between build commands. The bitbake server should reload the configuration files and recipe caches between builds, since they may have changed.

I think we need to revise this test.

Not a bug as per above comments.
