Markus Armbruster 97ca0712c8 qmp: Get rid of x-oob-test command 
tests/qmp-test tests an out-of-band command overtaking a slow in-band
command.  To do that, it needs:

1. An in-band command that *reliably* takes long enough to be
   overtaken.

2. An out-of-band command to do the overtaking.

3. To avoid delays, a way to make the in-band command complete quickly
   after it was overtaken.

To satisfy these needs, commit 469638f9cb provides the rather
peculiar oob-capable QMP command x-oob-test:

* With "lock": true, it waits for a global semaphore.

* With "lock": false, it signals the global semaphore.

To satisfy 1., the test runs x-oob-test in-band with "lock": true.
To satisfy 2. and 3., it runs x-oob-test out-of-band with "lock": false.

Note that waiting for a semaphore violates the rules for oob-capable
commands.  Running x-oob-test with "lock": true hangs the monitor
until you run x-oob-test with "lock": false on another monitor (which
you might not have set up).

Having an externally visible QMP command that may hang the monitor is
not nice.  Let's apply a little more ingenuity to the problem.  Idea:
have an existing command block on reading a FIFO special file, unblock
it by opening the FIFO for writing.

For 1., use

    {"execute": "blockdev-add",  "id": ID1,
     "arguments": {
        "driver": "blkdebug", "node-name": ID1, "config": FIFO,
        "image": { "driver": "null-co"}}}

where ID1 is an arbitrary string, and FIFO is the name of the FIFO.

For 2., use

    {"execute": "migrate-pause", "id": ID2, "control": {"run-oob": true}}

where ID2 is a different arbitrary string.  Since there's no migration
to pause, the command will fail, but that's fine; instant failure is
still a test of out-of-band responses overtaking in-band commands.

For 3., open FIFO for writing.

Drop QMP command x-oob-test.

#
# Notes: A guest may or may not respond to this command. This command

#
# Notes: This command will succeed if the guest is currently running. It

# available during the preconfig state (i.e. when the --preconfig command
# line option was in use).

# If no balloon device is present, DeviceNotActive
#
# Notes: This command just issues a request to the guest. When it returns,

#
# Notes: This command only exists as a stop-gap. Its use is highly

#
# Known limitations:

#
# @path: The path within the object model. There are two forms of supported
# paths--absolute and partial paths.
#
# Absolute paths are derived from the root object and can follow child<>
# or link<> properties. Since they can follow link<> properties, they
# can be arbitrarily long. Absolute paths look like absolute filenames
# and are prefixed with a leading slash.
#
# Partial paths look like relative filenames. They do not begin
# with a prefix. The matching rules for partial paths are subtle but
# designed to make specifying objects easy. At each level of the
# composition tree, the partial path is matched as an absolute path.
# The first match is not returned. At least two matches are searched
# for. A successful result is only returned if only one match is
# found. If more than one match is found, a flag is return to
# indicate that the match was ambiguous.
#
# @property: The property name to read
#
# Returns: The property value. The type depends on the property
# type. child<> and link<> properties are returned as #str
# pathnames. All integer property types (u8, u16, etc) are
# returned as #int.

# @change:

# This command is multiple commands multiplexed together.
#
# @device: This is normally the name of a block device but it may also be 'vnc'.

#
# @target: If @device is a block device, then this is the new filename.
# If @device is 'vnc', then if the value 'password' selects the vnc

# @dump-guest-memory:
#
# Dump guest's memory to vmcore. It is a synchronous operation that can take
# very long depending on the amount of guest memory.
#
# @paging: if true, do paging to get guest's memory mapping. This allows
# using gdb to process the core file.
#
# IMPORTANT: this option can make QEMU allocate several gigabytes
# of RAM. This can happen for a large guest, or a
# malicious guest pretending to be large.
#
# Also, paging=true has the following limitations:
#
# 1. The guest may be in a catastrophic state or can have corrupted
# memory, which cannot be trusted
# 2. The guest can be in real-mode even if paging is enabled. For
# example, the guest uses ACPI to sleep, and ACPI sleep state
# goes in real-mode
# 3. Currently only supported on i386 and x86_64.
#
# @protocol: the filename or file descriptor of the vmcore. The supported
# protocols are:
#
# 1. file: the protocol starts with "file:", and the following
# string is the file's path.
# 2. fd: the protocol starts with "fd:", and the following string
# is the fd's name.
#
# @detach: if true, QMP will return immediately rather than
# waiting for the dump to finish. The user can track progress
# using "query-dump". (since 2.6).
#
# @begin: if specified, the starting physical address.
#
# @length: if specified, the memory size, in bytes. If you don't
# want to dump all guest's memory, please specify the start @begin
# and @length
#
# @format: if specified, the format of guest memory dump. But non-elf
# format is conflict with paging and filter, ie. @paging, @begin and
# @length is not allowed to be specified with non-elf @format at the
# same time (since 2.0)

# Note: All boolean arguments default to false
