Subject: Make the shell run much faster for inputs where a single SQL statement spans
X-Git-Tag: version-3.6.10~5213
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=324ccefeb5aa530dd4a4672b57b42ca7cb0100bd;p=thirdparty%2Fsqlite.git

Make the shell run much faster for inputs where a single SQL statement spans
thousands of lines by avoiding the call to sqlite_complete() unless the
input ends in a semicolon. (CVS 860)
