2018-12-12monitor: Remove "x-oob", offer capability "oob" unconditionallyPeter Xu
Out-of-band command execution was introduced in commit cf869d53172. Unfortunately, we ran into a regression, and had to turn it into an experimental option for 2.12 (commit be933ffc23). http://lists.gnu.org/archive/html/qemu-devel/2018-03/msg06231.html The regression has since been fixed (commit 951702f39c7 "monitor: bind dispatch bh to iohandler context"). A thorough re-review of OOB commands led to a few more issues, which have also been addressed. This patch partly reverts be933ffc23 (monitor: new parameter "x-oob"), and makes QMP monitors again offer capability "oob" whenever they can provide it, i.e. when the monitor's character device is capable of running in an I/O thread. Some trivial touch-up in the test code is required to make sure qmp-test won't break.

2018-09-24json: Nicer recovery from lexical errorsMarkus Armbruster
When the lexer chokes on an input character, it consumes the character, emits a JSON error token, and enters its start state. This can lead to suboptimal error recovery. For instance, input 0123 , produces the tokens JSON_ERROR 01 JSON_INTEGER 23 JSON_COMMA , Make the lexer skip characters after a lexical error until a structural character ('[', ']', '{', '}', ':', ','), an ASCII control character, or '\xFE', or '\xFF'. Note that we must not skip ASCII control characters, '\xFE', '\xFF', because those are documented to force the JSON parser into known-good state, by docs/interop/qmp-spec.txt. The lexer now produces JSON_ERROR 01 JSON_COMMA , Update qmp-test for the nicer error recovery: QMP now reports just one error for input %p instead of two. Also drop the newline after %p; it was needed to tease out the second error.

2018-08-24json: Treat unwanted interpolation as lexical errorMarkus Armbruster
The JSON parser optionally supports interpolation. The lexer recognizes interpolation tokens unconditionally. The parser rejects them when interpolation is disabled, in parse_interpolation(). However, it neglects to set an error then, which can make json_parser_parse() fail without setting an error. Move the check for unwanted interpolation from the parser's parse_interpolation() into the lexer's finite state machine. When interpolation is disabled, '%' is now handled like any other unexpected character. The next commit will improve how such lexical errors are handled.

2018-07-03qmp: Don't let malformed in-band commands jump the queueMarkus Armbruster
handle_qmp_command() reports certain errors right away. This is wrong when OOB is enabled, because the errors can "jump the queue" then, as the previous commit demonstrates. To fix, we need to delay errors until dispatch. Do that for semantic errors, mostly by reverting ill-advised parts of commit cf869d53172 "qmp: support out-of-band (oob) execution". Bonus: doesn't run qmp_dispatch_check_obj() twice, once in handle_qmp_command(), and again in do_qmp_dispatch(). That's also due to commit cf869d53172.

2018-07-03qmp: Redo how the client requests out-of-band executionMarkus Armbruster
Commit cf869d53172 "qmp: support out-of-band (oob) execution" added a general mechanism for command-independent arguments just for an out-of-band flag: The "control" key is introduced to store this extra flag. "control" field is used to store arguments that are shared by all the commands, rather than command specific arguments. Let "run-oob" be the first. However, it failed to reject unknown members of "control". For instance, in QMP command {"execute": "query-name", "id": 42, "control": {"crap": true}} "crap" gets silently ignored. Instead of fixing this, revert the general "control" mechanism (because YAGNI), and do it the way I initially proposed, with key "exec-oob". Simpler code, simpler interface. An out-of-band command {"execute": "migrate-pause", "id": 42, "control": {"run-oob": true}} becomes {"exec-oob": "migrate-pause", "id": 42} Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-Id: <20180703085358.13941-13-armbru@redhat.com> [Commit message typo fixed]

2018-07-03qmp: Get rid of x-oob-test commandMarkus Armbruster
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 469638f9cb3 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.

2018-03-19qmp: introduce QMPCapabilityPeter Xu
There were no QMP capabilities defined. Define the first capability, "oob", to allow out-of-band messages. After this patch, we will allow QMP clients to enable QMP capabilities when sending the first "qmp_capabilities" command. Originally we are starting QMP session with no arguments like: { "execute": "qmp_capabilities" } Now we can enable some QMP capabilities using (take OOB as example, which is the only capability that we support): { "execute": "qmp_capabilities", "arguments": { "enable": [ "oob" ] } } When the "arguments" key is not provided, no capability is enabled. For capability "oob", the monitor needs to be run on a dedicated IO thread, otherwise the command will fail. For example, trying to enable OOB on a MUXed typed QMP monitor will fail. One thing to mention is that QMP capabilities are per-monitor, and also when the connection is closed due to some reason, the capabilities will be reset. Also, touch up qmp-test.c to test the new bits.

2018-03-02qapi: Empty out qapi-schema.jsonMarkus Armbruster
The previous commit improved compile time by including less of the generated QAPI headers. This is impossible for stuff defined directly in qapi-schema.json, because that ends up in headers that that pull in everything. Move everything but include directives from qapi-schema.json to new sub-module qapi/misc.json, then include just the "misc" shard where possible. It's possible everywhere, except: * monitor.c needs qmp-command.h to get qmp_init_marshal() * monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need qapi-event.h to get enum QAPIEvent Perhaps we'll get rid of those some other day. Adding a type to qapi/migration.json now recompiles some 120 instead of 2300 out of 5100 objects.

2018-02-14qmp-test: Drop dependence on global_qtestEric Blake
As a general rule, we prefer avoiding implicit global state because it makes code harder to safely copy and paste without thinking about the global state. Although qmp-test does not maintain parallel qtest connections, it was the last test assigning to global_qtest. It's just as easy to be explicit about the state; once all tests have been cleaned up, a later patch can then get rid of global_qtest and a layer of wrappers in libqtest.

2017-09-04qapi: Change data type of the FOO_lookup generated for enum FOOMarc-André Lureau
Currently, a FOO_lookup is an array of strings terminated by a NULL sentinel. A future patch will generate enums with "holes". NULL-termination will cease to work then. To prepare for that, store the length in the FOO_lookup by wrapping it in a struct and adding a member for the length. The sentinel will be dropped next.

2017-09-04tests/qmp-test: Add generic, basic test of query commandsMarkus Armbruster
A command is a query if it has no side effect and yields a result. Such commands are typically named query-FOO, but there are exceptions. The basic idea is to find candidates with query-qmp-schema, filter out the ones that aren't queries with an explicit blacklist, and test the remaining ones against a QEMU with no special arguments. The current blacklist is just add-fd. The test can't do queries with arguments, because it knows nothing about the arguments. No coverage for query-cpu-model-baseline, query-cpu-model-comparison, query-cpu-model-expansion, query-rocker, query-rocker-ports, query-rocker-of-dpa-flows, and query-rocker-of-dpa-groups. Most tested commands are expected to succeed. The test does not check the return value then. query-balloon and query-vm-generation-id are expected to fail because they need a virtio-balloon / vmgenid device to succeed, and this test is too dumb to set one up. Could be addressed later. query-acpi-ospm-status and query-hotpluggable-cpus are expected to fail because they require features provided only by special machine types, and this test is too dumb to set that up. Could also be addressed later. Several commands may either be functional or stubs that always fail, depending on build configuration. Ideally, the stubs shouldn't be in query-qmp-schema, but that requires QAPI schema compile-time configuration, which we don't have, yet. Until we do, we need to figure out whether a command is a stub. When we have a suitable CONFIG_FOO preprocessor symbol is available, use that. Else, simply blacklist the command for now. We get basic test coverage for the following commands, except as noted: qom-list-types query-acpi-ospm-status (expected to fail) query-balloon (expected to fail) query-block query-block-jobs query-blockstats query-chardev query-chardev-backends query-command-line-options query-commands query-cpu-definitions (blacklisted for now) query-cpus query-dump query-dump-guest-memory-capability query-events query-fdsets query-gic-capabilities (blacklisted for now) query-hotpluggable-cpus (expected to fail) query-iothreads query-kvm query-machines query-memdev query-memory-devices query-mice query-migrate query-migrate-cache-size query-migrate-capabilities query-migrate-parameters query-name query-named-block-nodes query-pci (blacklisted for now) query-qmp-schema query-rx-filter query-spice query-status query-target query-tpm query-tpm-models query-tpm-types query-uuid query-version query-vm-generation-id (expected to fail) query-vnc query-vnc-servers query-xen-replication-status Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <1502461148-10154-1-git-send-email-armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> [Typos in code under #ifndef and in the commit message fixed]
