QMimeDatabase::mimeTypeForFile(QString, MatchMode) doesn't work properly for mode == MatchContent

QMimeType QMimeDatabase::mimeTypeForFile(const QString & fileName, MatchMode mode = MatchDefault) const
does not work properly for QMimeDatabase::MatchContent. It will use MatchDefault instead.

You can see in the following code that if mode is not MatchExtension, it passes through to the mimeTypeForFile( const QFileInfo & fileInfo, MatchMode mode = MatchDefault) version but it doesn't pass along the mode argument which defaults to MatchDefault. Passing the mode argument to the QFileInfo version should fix the problem.

QMimeType QMimeDatabase::mimeTypeForFile(const QString &fileName, MatchMode mode) const
{
if (mode == MatchExtension) {
QMutexLocker locker(&d->mutex);
QStringList matches = d->mimeTypeForFileName(fileName);
const int matchCount = matches.count();
if (matchCount == 0)

{ return d->mimeTypeForName(d->defaultMimeType()); }

else if (matchCount == 1)

{ return d->mimeTypeForName(matches.first()); }

else

{ // We have to pick one. matches.sort(); // Make it deterministic return d->mimeTypeForName(matches.first()); }

} else

{ // Implemented as a wrapper around mimeTypeForFile(QFileInfo), so no mutex. QFileInfo fileInfo(fileName); return mimeTypeForFile(fileInfo); }

}
