2014-02-09qemu-iotest: Make 077 raw-onlyKevin Wolf
The qemu-io command sequences make the assumption that an unaligned request on the format layer will be unaligned on the blkdebug layer as well.

2014-01-31qemu-iotests: only run 071 on qcow2Stefan Hajnoczi
The 071 test is designed for IMGFMT=qcow2 because it uses the l2_load blkdebug event. Its output filtering also assumes that IMGFMT is not raw since 071.out contains "format=raw" but IMGFMT=raw would filter the output to "format=IMGFMT". Perhaps the test case can be rewritten to be more generic, but for now let's document that it was only supposed to work with qcow2.

2014-01-22iotests: Test new blkdebug/blkverify interfaceMax Reitz
Add a test for the new blkdebug/blkverify interface. This test is not written in Python, although it uses QMP. This is because it invokes the qemu-io HMP command, which outputs errors to stderr instead of returning them through QMP. Filtering and testing that output is easier in a shell script than with the Python infrastructure. Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2014-01-22block: Allow recursive "file"sMax Reitz
It should be possible to use a format as a driver for a file which in turn requires another file, i.e., nesting file formats. Allowing nested file formats results in e.g. qcow2 BlockDriverStates never being directly passed to bdrv_open_common() from bdrv_file_open(), but instead being handed through bdrv_open(). This changes the error message when trying to give a filename to qcow2, i.e. trying to use it as a driver for the protocol level. Therefore, change the reference output of I/O test 051 accordingly.

2013-12-06qemu-iotests: filter QEMU monitor \r\nStefan Hajnoczi
SMTP does not preserve newlines. This is normally not a problem if the email body uses DOS or UNIX newlines consistently. In 051.out we mix UNIX newlines with DOS newlines (since QEMU monitor output uses \r\n). This patch filters the QEMU monitor output so the golden master file uses UNIX newlines exclusively. The result is that patches touching 051.out will apply cleanly without mangling newlines after this commit. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

This patch moves ret assignment after reporting original error. We were lucky to pass qemu-iotests 048 (qemu-img compare case) but when I tried to run with TEST_DIR=/tmp (tmpfs), it fails with a "wrong" mismatch offset. This fixes two bugs. In the first if branch, setting ret to 1 before using it makes dead code in the next line: pnum is never added to mismatch offset even if ret was 0.
