2017-10-30nbd: Minimal structured read for clientVladimir Sementsov-Ogievskiy
Minimal implementation: for structured error only error_report error message. Note that test 83 is now more verbose, because the implementation prints more warnings about unexpected communication errors; perhaps future patches should tone things down by using trace messages instead of traces, but the common case of successful communication is no noisier than before.

2017-10-26qemu-io: Relax 'alloc' now that block-status doesn't assertEric Blake
Previously, the alloc command required that input parameters be sector-aligned and clamped to 32 bits, because the underlying bdrv_is_allocated used a 32-bit parameter and asserted aligned inputs. But now that we have fixed block status to report a 64-bit bytes value, and to properly round requests on behalf of guests, we can pass any values, and can use qemu-io to add coverage that our rounding is correct regardless of the guest alignment constraints. Update iotest 177 to intentionally probe block status at unaligned boundaries as well as with a bytes value that does not map to 32-bit sectors, which also required tweaking the image prep to leave an unallocated portion to the image under test.

2017-10-26qemu-img: Drop redundant error message in compareEric Blake
If a read error is encountered during 'qemu-img compare', we were printing the "Error while reading offset ..." message twice; this was because our helper function was awkward, printing output on some but not all paths. Fix it to consistently report errors on all paths, so that the callers do not risk a redundant message, and update the testsuite for the improved output. Further simplify the code by hoisting the conversion from an error message to an exit code into the helper function, rather than repeating that logic at all callers (yes, the helper function is now less generic, but it's a net win in lines of code).

2017-10-20libqtest: Add qtest_[v]startf()Eric Blake
We have several callers that were formatting the argument strings themselves; consolidate this effort by adding new convenience functions directly in libqtest, and update some call-sites that can benefit from it. Note that the new functions qtest_startf() and qtest_vstartf() behave more like qtest_init() (the caller must assign global_qtest after the fact, rather than getting it implicitly set). This helps us prepare for future patches that get rid of the global variable, by explicitly highlighting which tests still depend on it now.

2017-10-16tests/prom-env: Bump the timeout, and test pseries only in slow modeThomas Huth
If QEMU has been compiled with the flags --enable-tcg-interpreter and --enable-debug, the guest is running incredibly slow. The prom-env test is approximately 10 times slower than normal in this case, and it takes up to 500 seconds until the test with the pseries machine finishs. While we should still look for ways to speed up the test on the pseries machine here, let's bump the timeout to 600 seconds to allow the test to pass with this unusal configuration already now. Also move the pseries test into the "slow" category - since it is really a very slow test. Reviewed-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Thomas Huth <thuth@redhat.com>

However, to avoid that the default testing time increases too much, the additional NICs are only tested in the "make check SPEED=slow" mode.

2017-10-06iotests: Fix 195 if IMGFMT is part of TEST_DIRMax Reitz
do_run_qemu() in iotest 195 first applies _filter_imgfmt when printing qemu's command line and _filter_testdir only afterwards. Therefore, if the image format is part of the test directory path, _filter_testdir will no longer apply and the actual output will differ from the reference output even in case of success. For example, TEST_DIR might be "/tmp/test-qcow2", in which case _filter_imgfmt first transforms this to "/tmp/test-IMGFMT" which is no longer recognized as the TEST_DIR by _filter_testdir. Fix this by not applying _filter_imgfmt in do_run_qemu() but in run_qemu() instead, and only after _filter_testdir.

2017-10-06iotests: Add test 197 for covering copy-on-readEric Blake
Add a test for qcow2 copy-on-read behavior, including exposure for the just-fixed bugs. The copy-on-read behavior is always to a qcow2 image, but the test is careful to allow running with most image protocol/format combos as the backing file being copied from (luks being the exception, as it is harder to pass the right secret to all the right places). In fact, for './check nbd', this appears to be the first time we've had a qcow2 image wrapping NBD, requiring an additional line in _filter_img_create to match the similar line in _filter_img_info. Invoking blkdebug to prove we don't write too much took some effort to get working; and it requires that $TEST_WRAP (based on $TEST_DIR) not be subject to word splitting. We may decide later to have the entire iotests suite use relative rather than absolute names, to avoid problems inherited by the absolute name of $PWD or $TEST_DIR, at which point the sanity check in this commit could be simplified. This test requires at least 2G of consecutive memory to succeed; as such, it is prone to spurious failures, particularly on 32-bit machines under load. This situation is detected and triggers an early exit to skip the test, rather than a failure. To manually provoke this setup on a beefier machine, I used: $ (ulimit -S -v 1000000; ./check -qcow2 197) Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-10-06iotests: Restore stty settings on completionEric Blake
Executing qemu with a terminal as stdin will temporarily alter stty settings on that terminal (for example, disabling echo), because of how we run both the monitor and any multiplexing with guest input. Normally, qemu restores the original settings on exit; but if an iotest triggers qemu to abort in the middle, we can be left with the altered terminal setup. This can make life very annoying when debugging an iotest failure (not everyone remembers the trick of blind-typing 'stty sane' without echo, and some people prefer terminal settings that are slightly different than the defaults picked by 'stty sane'). It is possible to avoid qemu corrupting the terminal by not passing a terminal to qemu's stdin in the first place (as in, use './check ... </dev/null'), but that's extra typing to have to remember. But running 'exec </dev/null' in the harness seems like it might be too heavy of a hammer. So I instead went the the solution of saving and restoring the stty settings, only when the harness detects that it is run interactively. I tested this patch by forcing an allocation failure (I can't guarantee that this particular limit will work on all setups, but it shows the idea): $ (ulimit -S -v 500000; ./check -qcow2 1) Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2017-10-06commit: Remove overlay_bsKevin Wolf
We don't need to make any assumptions about the graph layout above the top node of the commit operation any more. Remove the use of bdrv_find_overlay() and related variables from the commit job code. bdrv_drop_intermediate() doesn't use the 'active' parameter any more, so we can just drop it. The overlay node was previously added to the block job to get a BLK_PERM_GRAPH_MOD. We really need to respect those permissions in bdrv_drop_intermediate() now, but as long as we haven't figured out yet how BLK_PERM_GRAPH_MOD is actually supposed to work, just leave a TODO comment there. With this change, it is now possible to perform another block job on an overlay node without conflicts. qemu-iotests 030 is changed accordingly.

2017-10-06qemu-iotests: Allow QMP pretty printing in common.qemuKevin Wolf
QMP responses to certain commands can become quite long, which doesn't only make reading them hard, but also means that the maximum line length in patch emails can be exceeded. Allow tests to switch to QMP pretty printing, which results in more, but shorter lines. We also need to make sure to keep indentation in the response for this to work as expected.
