2013-10-30qemu-iotests: prefill some data to test imageFam Zheng1-0/+4
Case 030 occasionally fails because of block job compltes too fast to be captured by script, and 'unexpected qmp event' of job completion causes the test failure. Simply fill in some data to the test image to make this false alarm less likely to happen. (For other benefits to prefill data to test image, see also commit ab68cdfaa).

2013-10-30qemu-iotests: Test case for backing file deletionMax Reitz3-0/+68
Add a test case for trying to open an image file where it is impossible to open its backing file (in this case, because it was deleted). When doing this, qemu (or qemu-io in this case) should not crash but rather print an appropriate error message.

2013-10-28tests: Multiboot mmap test caseKevin Wolf9-0/+584
This adds a test case for Multiboot memory map in the tests/multiboot directory, where future i386 test kernels can be dropped. Because this requires an x86 build host and an installed 32 bit libgcc, the test is not part of a regular 'make check'. The reference output for the test is verified against test runs of the same multiboot kernel booted by some GRUB 0.97. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

IF_NONE allows read-only, which makes forbidding it in this place for other types pretty much pointless. Instead, make sure that all devices for which the check would have errored out check in their init function that they don't get a read-only BlockDriverState.

2013-10-11tests: build the helper program by defaultWenchao Xia1-1/+7
Usually we may configure and make, then goto ./tests/qemu-iotest, check. In this case an error will happen since helper program was not built. This patch simply build it by default. A better way may be introducing Makefile in ./tests/qemu-iotest, but it is more complicate to handle out of tree case, and a bit overkill for a single file now, we can do that when more files come.

2013-10-11block: qemu-iotests for vhdx, read sample dynamic imageJeff Cody6-1/+86
This adds the VHDX format to the qemu-iotests format, and adds a read test. The test reads from an existing sample image, that was created with Hyper-V under Windwos Server 2012. The image file is a 1GB dynamic image, with 32MB blocks. The pattern 0xa5 exists from 0MB-33MB (past a block size boundary) The pattern 0x96 exists from 33MB-66MB (past another block boundary, and leaving a partial blank block) From 66MB-1024MB, all reads should return 0. Although 1GB dynamic image with 66MB of data, the bzip2'ed image file size is only 874 bytes. This also adds in the IMGFMT_GENERIC flag, so r/o images can be tested (e.g. ./check -vhdx) without failing tests that assume r/w support.

2013-10-11qemu-iotests: Additional info from qemu-img infoMax Reitz4-0/+135
Add a test for the additional information now provided by qemu-img info when used on qcow2 images. It also tests the qemu QMP output from the query-block command when running qemu with different runtime options than specified in the image (ImageInfoSpecific should always refer to the image).

2013-10-11qemu-iotests: Discard specific info in _img_infoMax Reitz1-1/+19
In _img_info, filter out additional information specific to the image format provided by qemu-img info, since tests designed for multiple image formats would produce different outputs for every image format otherwise. In a human-readable dump, that new information will always be last for each "image information block" (multiple blocks are emitted when inspecting the backing file chain). Every block is separated by an empty line. Therefore, in this case, everything starting with the line "Format specific information:" up to that empty line (or EOF, if it is the last block) has to be stripped. The JSON dump will always emit pretty JSON data. Therefore, the opening and closing braces of every object will be on lines which are indented by exactly the same amount, and all lines in between will have more indentation. Thus, in this case, everything starting with a line matching the regular expression /^ *"format-specific": {/ until /^ *},?/ has to be stripped, where the number of spaces at the beginning of the respective lines is equal.

2013-09-27qemu-iotests: Add basic ability to use binary sample imagesJeff Cody3-0/+35
For image formats that are not "QEMU native", but supported for compatibility, it is useful to verify that an image created with the 'gold standard' native tool can be read / written to successfully by QEMU. In addition to testing non-native images, this could also be useful to test against image files created by older versions of QEMU. This provides a directory to store small sample images, for use by scripts in tests/qemu-iotests. Image files should be compressed with bzip2. To use a sample image from a bash script, the _use_sample_img function will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to be the decompressed sample image copy. To cleanup, call _cleanup_test_img as normal. Signed-off-by: Jeff Cody <jcody@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

Test 038 uses asynchronous I/O, resulting (potentially) in a different output for every run (regarding the order of the I/O accesses).

2013-09-12qemu-iotests: Adjustments due to error propagationMax Reitz6-40/+24
When opening/creating images, propagating errors instead of immediately emitting them on occurrence results in errors generally being printed on a single line rather than being split up into multiple ones. This in turn requires adjustments to some test results. Also, test 060 used a sed to filter out the test image directory and format by removing everything from the affected line after a certain keyword; this now also removes the error message itself, which can be fixed by using _filter_testdir and _filter_imgfmt. Finally, _make_test_img in common.rc did not filter out the test image directory etc. from stderr. This has been fixed through a redirection of stderr to stdout (which is already done in _check_test_img and _img_info). Signed-off-by: Max Reitz <mreitz@redhat.com>

The reference output for test case 026 hasn't been updated in a long time and it's one of the "known failing" cases. This patch updates the reference output so that unintentional changes can be reliably detected again. The problem with this test case is that it produces different output depending on whether -nocache is used or not. The solution of this patch is to actually have two different reference outputs. If nnn.out.nocache exists, it is used as the reference output for -nocache; otherwise, nnn.out stays valid for both cases.
