2009-07-10qemu-io: fix memory leakKevin Wolf
qemu-io leaks the request buffer whenever the read or write function isn't executed completely down the "normal" code path. [hch: also fix the aio and vectored variants the same way] Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
2009-07-10qemu-io: add flag to mark files growableChristoph Hellwig
Add a -g flag to the open command and the main qemu-io command line to allow opening a file growable. This is only allowed for protocols, mirroring the limitation exposed through bdrv_file_open. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Kevin Wolf <kwolf@redhat.com>
2009-07-10qemu-io: better input validation for vector-based commandsChristoph Hellwig
Fix up a couple of issues with validating the input of the various length arguments for the vectored I/O commands: - do the alignment check on each length instead the always 0 count argument - use a long long varibale for the cvtnum return value so that we can check wether it wasn't a number - check for a too large argument instead of truncating it Also refactor it into a common helper for all four calers and avoid parsing the numbers twice.

2009-06-24qemu-io: add aio read/write/flush commandsChristoph Hellwig
Add commands to exercise asynchronous reads/writes and to flush all outstanding aio commands. Commands to exercise aio cancellations will follow in a separate patch. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-06-24Fix dump output in qemu-io.Stefan Weil
The dump output was not nicely formatted for bytes larger than 0x7f, because signed values expanded to sizeof(int) bytes. So for example 0xab did not print as "ab", but as "ffffffab". I also cleaned the function prototype, which avoids new type casts and allows to remove an existing type cast.

2009-05-01qemu-io: Optionally verify only part of read dataKevin Wolf
There are reasonable test cases where a read must span areas that are not uniformly filled with one pattern but contains several parts. This makes -P useless for them currently. Introducing additional options which determine the part of the read data that should be verified with the given pattern allows to check such reads.

2009-04-18qemu-io: Verify read data by patterns (Kevin Wolf)aliguori
This patch adds a -P option to read and readv which allows to compare the read data to a given pattern. This can be used to verify data written by write -P.

2009-04-18qemu-io: Fix handling of bdrv_is_allocated() return value (Kevin Wolf)aliguori
bdrv_is_allocated() returns a boolean which indicates if the offset is allocated, not 0 on success and everything else is an error.

2009-04-18a couple of qemu-io fixes (Christoph Hellwig)aliguori
Fix two stupid bugs that I forgot to push out: - qiov->size already is in bytes, no need to shift it - actually use the supplied patter in the writev command Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@7178 c046a42c-6fe2-441c-8c8c-71466251a162
