I created a pretty simple archive: /root /root/dir /root/dir/file1: contents of file1 /root/dir/file2: contents of file2 /root/dir/file3: contents of file3 And then set up a simple test case: Header: https://paste.kde.org/p8jkzlcgg/u5oiqj Implementation: https://paste.kde.org/pt1yeawj1/t8sg8j Then this happens: [...] QWARN : KCompressionDeviceTest::testXzNetworkReplyDevice() QIODevice::seek: Cannot call seek on a sequential device QWARN : KCompressionDeviceTest::testXzNetworkReplyDevice() QIODevice::seek: Cannot call seek on a sequential device QWARN : KCompressionDeviceTest::testXzNetworkReplyDevice() QIODevice::seek: Cannot call seek on a sequential device QWARN : KCompressionDeviceTest::testXzNetworkReplyDevice() QIODevice::seek: Cannot call seek on a sequential device QWARN : KCompressionDeviceTest::testXzNetworkReplyDevice() QIODevice::seek: Cannot call seek on a sequential device QSYSTEM: KCompressionDeviceTest::testXzNetworkReplyDevice() Maximum amount of warnings exceeded. Use -maxwarnings to override. Then the test freezes. I have to interrupt it so that it finishes. What's wrong? -- Luiz Romário Santana Rios
