2012-10-05rtc: implement century bytePaolo Bonzini
Implement the century byte in the RTC emulation, and test that it works. This leads to some annoying compatibility code because we need to treat a value of 2000 for the base_year property as "use the century byte properly" (which would be a value of 0). The century byte will now be always-zero, rather than always-20, for the MIPS Magnum machine whose base_year is 1980. Commit 42fc73a (Support epoch of 1980 in RTC emulation for MIPS Magnum, 2009-01-24) correctly said: With an epoch of 1980 and a year of 2009, one could argue that [the century byte] should hold either 0, 1, 19 or 20. NT 3.50 on MIPS does not read the century byte. so I picked the simplest and most sensible implementation which is to return 0 for 1980-2079, 1 for 2080-2179 and so on.

2012-10-05rtc: fix overflow in mktimegmPaolo Bonzini
When setting a date in 1980, Linux is actually disregarding the century byte and setting the year to 2080. This causes a year-2038 overflow in mktimegm. Fix this by doing the days-to-seconds computation in 64-bit math.

2012-10-05qtest: implement QTEST_STOPPaolo Bonzini
It is quite difficult to debug qtest test cases without extra wrapper scripts for QEMU or similar. This patch adds a simple environment variable-based trigger that sends a STOP signal to the QEMU instance under test, before attempting to connect to its QMP session. This will block execution of the testcase and give time to attach a debugger to the stopped QEMU process.

2012-09-28qemu-iotests: add tests for streaming error handlingPaolo Bonzini
Add a test for each of report/ignore/stop. The tests use blkdebug to generate an error in the middle of a script.

2012-09-28qemu-iotests: map underscore to dash in QMP argument namesPaolo Bonzini
iotests.py provides a convenience function that uses Python keyword arguments to represent QMP command arguments. However, almost all QMP commands use dashes for argument names (the sole exception is block_set_io_throttle), and dashes are not allowed in a keyword argument name. Hence provide automatic conversion of underscores to dashes.

2012-09-28qemu-iotests: add test for pausing a streaming operationPaolo Bonzini
These check that a paused streaming job does not advance its offset. Sometimes the new test fails; the map is different between the source and the destination of the streaming because qemu-io does not always pack adjacent clusters that have the same allocated/unallocated state. However, this also happens with the existing test_stream testcase, and is better fixed in qemu-io.

2012-08-10block: add BLOCK_O_CHECK for qemu-img checkStefan Hajnoczi
Image formats with a dirty bit, like qed and qcow2, repair dirty image files upon open with BDRV_O_RDWR. Performing automatic repair when qemu-img check runs is not ideal because the bdrv_open() call repairs the image before the actual bdrv_check() call from qemu-img.c. Fix this "double repair" since it leads to confusing output from qemu-img check. Tell the block driver that this image is being opened just for bdrv_check(). This skips automatic repair and qemu-img.c can invoke it manually with bdrv_check(). Update the golden output for qemu-iotests 039 to reflect the new qemu-img check output.

qemu-iotests already filters out image creation options that may be present or not in order to get the same output in both cases. However, often it only considers the default value of the option.

2012-08-06qemu-iotests: add 039 qcow2 lazy refcounts testStefan Hajnoczi
This tests establishes the basic post-conditions of the qcow2 lazy refcounts features: 1. If the image was closed normally, it is marked clean. 2. If an allocating write was performed and the image was not closed normally, then it is marked dirty. a. Written data can be read back successfully. b. The image file can be repaired and will be marked clean again. c. The image file is automatically repaired when opened read/write.

2012-08-06qcow2: implement lazy refcountsStefan Hajnoczi
Lazy refcounts is a performance optimization for qcow2 that postpones refcount metadata updates and instead marks the image dirty. In the case of crash or power failure the image will be left in a dirty state and repaired next time it is opened. Reducing metadata I/O is important for cache=writethrough and cache=directsync because these modes guarantee that data is on disk after each write (hence we cannot take advantage of caching updates in RAM). Refcount metadata is not needed for guest->file block address translation and therefore does not need to be on-disk at the time of write completion - this is the motivation behind the lazy refcount optimization. The lazy refcount optimization must be enabled at image creation time: qemu-img create -f qcow2 -o compat=1.1,lazy_refcounts=on a.qcow2 10G qemu-system-x86_64 -drive if=virtio,file=a.qcow2,cache=writethrough Update qemu-iotests 031 and 036 since the extension header size changes when we add feature bit table entries.

2012-08-06qemu-iotests: ignore qemu-img create lazy_refcounts outputStefan Hajnoczi
Hide the default lazy_refcounts=off output from qemu-img like we do with other image creation options. This ensures that existing golden outputs continue to pass despite the new option that has been added. Note that this patch applies before the one that actually introduces the lazy_refcounts=on|off option. This ensures git-bisect(1) continues to work.

2012-06-15qemu-iotests: fill streaming test image with dataPaolo Bonzini
The TestStreamStop test case is racy; if the job completes before we can cancel it, it fails. If we remove the sleep the job will be canceled before it has even started, and the test succeeds but it is also not testing anything interesting. But if the image is left sparse, then the job has really nothing to do. For qcow2 it will read one L2-table, for raw it will issue a bunch of ioctls. This also falls under "not testing anything interesting", and this may be happening right now (depending on the filesystem) since the file protocol got an is_allocated method. Filling the test image with data ensures that the test covers the intended case. It also slows down the test, which will be particularly important after the next patch.
