Author: stefan2

New Revision: 983770

URL: http://svn.apache.org/viewvc?rev=983770&view=rev
Log:
When reading cache-able full text from the DB, pre-allocate the
respective buffer to the expected size of the full text.

* subversion/libsvn_fs_fs/fs_fs.c
  (rep_read_get_baton): allocate just as much space for the fulltext
  buffer as will probably be needed to hold it.
