New Revision: 1795323
URL: http://svn.apache.org/viewvc?rev=1795323&view=rev
Log:
Minor FSFS cache usage tuning by eliminating a few lookups that
cannot be successful.
* subversion/libsvn_fs_fs/cached_data.c
(create_rep_state_body): Unless "block read" is enabled, the
raw window cache won't be populated.
(build_rep_list): Combined windows only get cached when the
whole rep fits into a single window.
