Hmmm... let me examine 17b15d4 (gitweb: File based caching layer
(from git.kernel.org), 2010-11-01)

Ah, I see.  It looks like I forgot to update git_blob_plain and 
git_snapshot when I was modifying original patch by J.H. (which didn't
pass test suite for other reasons) to have test for $caching_enabled
outside cache_fetch().

Could you try if the following patch applied on top of 17b15d4 fixes
it for you?  If it does, I'll resend fixed series (yet again, I'm sorry
Junio).

It is not most elegant solution.


Sidenote: 

  open BINOUT, '>', \$fullhashbinpath

should open in-memory file, and not be equivalent to

  open BINOUT, '>', "\$fullhashbinpath"

Hmmm... in the case of !$caching_enabled, $fullhasbinpath is *STDOUT.


BTW replacing 

  open BINOUT, '>', \$fullhashbinpath

with

  open BINOUT, '>&STDOUT'

or

  open BINOUT, '>&', \$fullhashbinpath

could be simpler, alternate solution.
