[Qt-interest] Compressing sqlite file with QtIOCompressor results in corrupted db

[Jan]

Hi all,

I am compressing/uncompressing a sqlite db file with QtIOCompressor.

The file size seems to be ok after uncompressing and I am able to open 
the database but any query will fail with: "File is encrypted or not a 
database".
Do I need to set any other options?

This is the code:

//compressing
QFile fileIn("in");
fileIn.open(QIODevice::ReadOnly);
QByteArray ba = fileIn.readAll();

QFile outFile("out");
QtIOCompressor compressor(&outFile);
compressor.open(QIODevice::WriteOnly);
compressor.write(ba);
compressor.close();

//uncompressing
QFile compsqlite("out");
QFile sqlite("sqlite");

QtIOCompressor compressor(compsqlite);
compressor.open(QIODevice::ReadOnly);
const QByteArray ba = compressor.readAll();

sqlite.open(QIODevice::WriteOnly);
QDataStream out(&sqlite);

compressor.close();
out << ba;
