Stefan Hajnoczi 1b7650ef2f qemu-iotests: only run 071 on qcow2
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.

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

Max Reitz 505d758334 block: Allow recursive "file"s
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.

Stefan Hajnoczi ac9524dc55 qemu-iotests: filter QEMU monitor \r\n
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.

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"

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.

In the other if branch, currently the output error is always -4:

Fam Zheng b04b6b6ec3 block: Print its file name if backing file opening failed
If backing file doesn't exist, the error message is confusing and
misleading:

    $ qemu /tmp/a.qcow2
    qemu: could not open disk image /tmp/a.qcow2: Could not open file: No
    such file or directory

But...

    $ ls /tmp/a.qcow2
    /tmp/a.qcow2

    $ qemu-img info /tmp/a.qcow2
    image: /tmp/a.qcow2
    file format: qcow2
    virtual size: 8.0G (8589934592 bytes)
    disk size: 196K
    cluster_size: 65536
    backing file: /tmp/b.qcow2

Because...

    $ ls /tmp/b.qcow2
    ls: cannot access /tmp/b.qcow2: No such file or directory

This is not intuitive. It's better to have the missing file's name in
the error message. With this patch:

    $ qemu-io -c 'read 0 512' /tmp/a.qcow2
    qemu-io: can't open device /tmp/a.qcow2: Could not open backing
    file: Could not open '/stor/vm/arch.raw': No such file or directory
    no file open, try 'help open'

This tests the replay of a data sector in a VHDX image file.

The image file is a 10G dynamic image, with 4MB block size.  The

This adds the VHDX format to the qemu-iotests format, and adds

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

Max Reitz 4c2e946500 qemu-iotests: Discard specific info in _img_info
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.

Jeff Cody 85edbd375b qemu-iotests: Add basic ability to use binary sample images
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.

Max Reitz 2c78857bf6 qemu-iotests: Adjustments due to error propagation
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).

Kevin Wolf 8f94b07787 qemu-iotests: Fixed test case 026
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.
