Subject: mdocml: Since old SQLite versions do not have sqlite3_errstr(), provide
Date: Tue, 5 Aug 2014 08:50:52 -0400 (EDT) [thread overview]
Message-ID: <201408051250.s75CoqmX015806@krisdoz.my.domain> (raw)
Log Message:
-----------
Since old SQLite versions do not have sqlite3_errstr(),
provide a dummy fallback implementation.
Do not bother to decode the error, SQLite error codes
are not useful enough for that to be worthwhile.
Note that using sqlite3_errmsg(db) would be a bad idea:
On malloc() failure, db is NULL, which would cause a segfault.
Issue noticed by kristaps@.
