Subject: fix performance issues with SQLite 3.8 and false positive test failures
Upstream: committed
References: https://svn.apache.org/viewvc?view=revision&revision=1542765
https://svn.apache.org/viewvc?view=revision&revision=1542767
https://svn.apache.org/viewvc?view=revision&revision=1542774
Addresses performance issues with SQLite 3.8 and fixes false
positive test failes in wc-queries-tests. Allows dynamic linking
against SQLite 3.8 in openSUSE > 13.1. The patch below is combined
from the three upstream commits, with upstream adjustments in last
hunk of wc-queries-test.c adjusted for differences upstream.
While this does not create a new working copy format version,
working copies that were created with a 1.8 client linked against
SQLite 3.7 need to have "svn upgrade" run once to enjoy the benefits
while otherwise maintaining compatibility. The step is optional and
not required for new working copies.
Upstream, this set is currently proposed for backporting into 1.8.x.
