      qapi: Add tests of redefined expressions · cfdd5bca
      由 Eric Blake 提交于 
      Demonstrate that the qapi generator doesn't deal very well with
redefined expressions.  At the parse level, they are silently
accepted; and while the testsuite just stops at parsing, I've
further tested that many of them cause generator crashes or
invalid C code if they were appended to qapi-schema-test.json.
A later patch will tighten things up and adjust the testsuite
to match.

      qapi: Add some expr tests · 9050c65b
      由 Eric Blake 提交于 
      Demonstrate that the qapi generator doesn't deal well with
expressions that aren't up to par. Later patches will improve
the expected results as the generator is made stricter.  Only
a few of the the added tests actually behave sanely at
rejecting obvious problems or demonstrating success.

Note that in some cases, we reject bad QAPI merely because our
pseudo-JSON parser does not yet know how to parse numbers.  This
series does not address that, but when a later series adds support
for numeric defaults of integer fields, the testsuite will ensure
that we don't lose the error (and hopefully that the error
message quality is improved).

      qapi: Add some union tests · 3d0c4829
      由 Eric Blake 提交于 
      Demonstrate that the qapi generator doesn't deal well with unions
that aren't up to par. Later patches will update the expected
reseults as the generator is made stricter.  A few tests work
as planned, but most show poor or missing error messages.

Of particular note, qapi-code-gen.txt documents 'base' only for
flat unions, but the tests here demonstrate that we currently allow
a 'base' to a simple union, although it is exercised only in the
testsuite.  Later patches will remove this undocumented feature, to
give us more flexibility in adding other future extensions to union
types.  For example, one possible extension is the idea of a
type-safe simple enum, where added fields tie the discriminator to
a user-defined enum type rather than creating an implicit enum from
the names in 'data'.  But adding such safety on top of a simple
enum with a base type could look ambiguous with a flat enum;
besides, the documentation also mentions how any simple union can
be represented by an equivalent flat union.  So it will be simpler
to just outlaw support for something we aren't using.

actually supported this particular configuration, ignored for simplicity.

For machines pc-*-1.5+ test QMP cpu-add with monotonically increasing ID,
and test for graceful failure otherwise.

      libqos/ahci: create libqos/ahci.c · 9a75b0a0
      由 John Snow 提交于 
      With global state removed, code responsible for booting up,
verifying, and initializing the AHCI HBA is extracted and
inserted into libqos/ahci.c, which would allow for other
qtests in the future to quickly grab a meaningfully initialized
reference to an AHCI HBA.

Even without other users, functionalizing and isolating the code
assists future AHCI tests that exercise Q35 migration.

For now, libqos/ahci.o will be PC-only, but can be expanded into
something arch-agnostic in the future, if needed.

      libqos: create libqos.c · dd0029c0
      由 John Snow 提交于 
      The intent of this file is to serve as a misc. utilities file to be
shared amongst tests that are utilizing libqos facilities.

In a later patch, migration test helpers will be added to libqos.c that
will allow simplified testing of migration cases where libqos is
"Just Enough OS" for migrations testing.

The addition of the AHCIQState structure will also allow us to eliminate
global variables inside of qtests to manage allocators and test instances
in a better, more functional way.

libqos.c:
        - Add qtest_boot
        - Add qtest_shutdown

libqos.h:
        - Create QOSState structure for allocator and QTestState.

ahci-test.c:
        - Move qtest_boot and qtest_shutdown to libqos.c/h
        - Create AHCIQState to interface with new qtest_boot/shutdown prototypes
        - Modify tests slightly to use new types.

For now, the new object file is only linked to ahci-test, because it still
relies on pc architecture specific code in libqos. The next two patches will
reorganize the code to be more general.

      block: add event when disk usage exceeds threshold · e2462113
      由 Francesco Romani 提交于 
      Managing applications, like oVirt (http://www.ovirt.org), make extensive
use of thin-provisioned disk images.
To let the guest run smoothly and be not unnecessarily paused, oVirt sets
a disk usage threshold (so called 'high water mark') based on the occupation
of the device,  and automatically extends the image once the threshold
is reached or exceeded.

In order to detect the crossing of the threshold, oVirt has no choice but
aggressively polling the QEMU monitor using the query-blockstats command.
This lead to unnecessary system load, and is made even worse under scale:
deployments with hundreds of VMs are no longer rare.

To fix this, this patch adds:
* A new monitor command `block-set-write-threshold', to set a mark for
  a given block device.
* A new event `BLOCK_WRITE_THRESHOLD', to report if a block device
  usage exceeds the threshold.
* A new `write_threshold' field into the `BlockDeviceInfo' structure,
  to report the configured threshold.

This will allow the managing application to use smarter and more
efficient monitoring, greatly reducing the need of polling.

[Updated qemu-iotests 067 output to add the new 'write_threshold'
property. --Stefan]
[Changed g_assert_false() to !g_assert() to fix the build on older glib
versions. --Kevin]

      migration: Append JSON description of migration stream · 8118f095
      由 Alexander Graf 提交于 
      One of the annoyances of the current migration format is the fact that
it's not self-describing. In fact, it's not properly describing at all.
Some code randomly scattered throughout QEMU elaborates roughly how to
read and write a stream of bytes.

We discussed an idea during KVM Forum 2013 to add a JSON description of
the migration protocol itself to the migration stream. This patch
adds a section after the VM_END migration end marker that contains
description data on what the device sections of the stream are composed of.

This approach is backwards compatible with any QEMU version reading the
stream, because QEMU just stops reading after the VM_END marker and ignores
any data following it.

With an additional external program this allows us to decipher the
contents of any migration stream and hopefully make migration bugs easier
to track down.

      tests: disable global props test for old glib · 9d41401b
      由 Michael S. Tsirkin 提交于 
      follow-up patch moves global property tests to subprocesses.
Unfortunately with old glib this causes:

tests/test-qdev-global-props.c: In function
‘test_static_prop’:
tests/test-qdev-global-props.c:80:5: error: implicit
declaration of function ‘g_test_trap_subprocess’
[-Werror=implicit-function-declaration]
tests/test-qdev-global-props.c:80:5: error: nested extern
declaration of ‘g_test_trap_subprocess’ [-Werror=nested-externs]

This function was only added in glib 2.38, and our
minimum version is 2.12.

To fix, disable the test for glib < 2.38.

Apply before that patch to avoid breaking bisect.
