Subject: The sqlite3_str_new() interface never returns NULL, even after an OOM.
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=a2116f86b09b23220eb9dd94ba6a54e1450f0c67;p=thirdparty%2Fsqlite.git

The sqlite3_str_new() interface never returns NULL, even after an OOM.
Code that uses that interface should invoke sqlite3_str_errcode() to see
if an OOM has occurred.
