Minimum code to reproduce
import Database.HDBC
import Database.HDBC.Sqlite3
main :: IO ()
main = do
c <- connectSqlite3 "some.db"
r <- quickQuery c "select 1;" []
disconnect c
print r
Expected result
Raise an error to tell the connection is already closed,
similarly to putStrLn =<< (withFile "file" ReadMode $ hGetContents).
Actual result
Only an empty list [] is printed without any error.
This can make it very hard to detect I used lazy IO in a wrong way.
My environment
- HDBC-sqlite3-2.3.3.1
- HDBC-2.4.0.2
- SQLite: 3.22.0
- GHC 8.2.2
- Windows 10 64bit
