Subject: Ensure that the Parse.nErr flag is set following an SQLITE_TOOBIG error on
X-Git-Tag: version-3.39.1~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8d7ffd29047f7326aa73f24b64d6f38108049ff8;p=thirdparty%2Fsqlite.git

Ensure that the Parse.nErr flag is set following an SQLITE_TOOBIG error on
a nested parse.  Fix for the problem identified by
[forum/forumpost/d5a82ba9eedee30c | forum post d5a82ba9eedee30c].
Also, remove unnecessary clearing of the Parse.zErrMsg field
following a nested parse.
