2020-01-12test: Move qtests to a separate directoryThomas Huth
The tests directory itself is pretty overcrowded, and it's hard to see which test belongs to which test subsystem (unit, qtest, ...). Let's move the qtests to a separate folder for more clarity.

2019-12-17vl: configure accelerators from -accel optionsPaolo Bonzini
Drop the "accel" property from MachineState, and instead desugar "-machine accel=" to a list of "-accel" options. This has a semantic change due to removing merge_lists from -accel. For example: - "-accel kvm -accel tcg" all but ignored "-accel kvm". This is a bugfix. - "-accel kvm -accel thread=single" ignored "thread=single", since it applied the option to KVM. Now it fails due to not specifying the accelerator on "-accel thread=single". - "-accel tcg -accel thread=single" chose single-threaded TCG, while now it will fail due to not specifying the accelerator on "-accel thread=single". Also, "-machine accel" and "-accel" become incompatible. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

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.

2018-08-24json: Pass lexical errors and limit violations to callbackMarkus Armbruster
The callback to consume JSON values takes QObject *json, Error *err. If both are null, the callback is supposed to make up an error by itself. This sucks. qjson.c's consume_json() neglects to do so, which makes qobject_from_json() null instead of failing. I consider that a bug. The culprit is json_message_process_token(): it passes two null pointers when it runs into a lexical error or a limit violation. Fix it to pass a proper Error object then. Update the callbacks: * monitor.c's handle_qmp_command(): the code to make up an error is now dead, drop it. * qga/main.c's process_event(): lumps the "both null" case together with the "not a JSON object" case. The former is now gone. The error message "Invalid JSON syntax" is misleading for the latter. Improve it to "Input must be a JSON object". * qobject/qjson.c's consume_json(): no update; check-qjson demonstrates qobject_from_json() now sets an error on lexical errors, but still doesn't on some other errors. * tests/libqtest.c's qmp_response(): the Error object is now reliable, so use it to improve the error message.

2018-08-24json: Redesign the callback to consume JSON valuesMarkus Armbruster
The classical way to structure parser and lexer is to have the client call the parser to get an abstract syntax tree, the parser call the lexer to get the next token, and the lexer call some function to get input characters. Another way to structure them would be to have the client feed characters to the lexer, the lexer feed tokens to the parser, and the parser feed abstract syntax trees to some callback provided by the client. This way is more easily integrated into an event loop that dispatches input characters as they arrive. Our JSON parser is kind of between the two. The lexer feeds tokens to a "streamer" instead of a real parser. The streamer accumulates tokens until it got the sequence of tokens that comprise a single JSON value (it counts curly braces and square brackets to decide). It feeds those token sequences to a callback provided by the client. The callback passes each token sequence to the parser, and gets back an abstract syntax tree. I figure it was done that way to make a straightforward recursive descent parser possible. "Get next token" becomes "pop the first token off the token sequence". Drawback: we need to store a complete token sequence. Each token eats 13 + input characters + malloc overhead bytes. Observations: 1. This is not the only way to use recursive descent. If we replaced "get next token" by a coroutine yield, we could do without a streamer. 2. The lexer reports errors by passing a JSON_ERROR token to the streamer. This communicates the offending input characters and their location, but no more. 3. The streamer reports errors by passing a null token sequence to the callback. The (already poor) lexical error information is thrown away. 4. Having the callback receive a token sequence duplicates the code to convert token sequence to abstract syntax tree in every callback. 5. Known bug: the streamer silently drops incomplete token sequences. This commit rectifies 4. by lifting the call of the parser from the callbacks into the streamer. Later commits will address 3. and 5. The lifting removes a bug from qjson.c's parse_json(): it passed a pointer to a non-null Error * in certain cases, as demonstrated by check-qjson.c. json_parser_parse() is now unused. It's a stupid wrapper around json_parser_parse_err(). Drop it, and rename json_parser_parse_err() to json_parser_parse().

2018-08-24test-qga: Clean up how we test QGA synchronizationMarkus Armbruster
To permit recovering from arbitrary JSON parse errors, the JSON parser resets itself on lexical errors. We recommend sending a 0xff byte for that purpose, and test-qga covers this usage since commit 5229564b832. That commit had to add an ugly hack to qmp_fd_vsend() to make capable of sending this byte (it's designed to send only valid JSON). The previous commit added a way to send arbitrary text.

2018-08-23tests: Skip old versioned machine types in quick testing modeThomas Huth
The tests that check something for all machine types currently spend a lot of time checking old machine types (like "pc-i440fx-2.0" for example). The chances that we find something new there in addition to checking the latest version of a machine type are pretty low, so we should not waste the time of the developers by testing this again and again in the "quick" testing mode. Thus let's add some code to determine whether we are testing a current machine type or an old one, and only test the old types if we are running in "SPEED=slow" mode. This decreases the testing time quite a bit now, e.g. the qom-test now finishes within 4 seconds for qemu-system-x86_64 instead of 30 seconds when testing all machines.

2018-08-16libqtest: Improve error reporting for bad read from QEMUMarkus Armbruster
When read() from the qtest socket or the QMP socket fails or EOFs, we report "Broken pipe" and exit(1). This commonly happens when QEMU crashes. It also happens when QEMU refuses to run because the test passed it bad arguments. Sadly, we neglect to report either. Improve this by calling abort() instead of exit(1), so kill_qemu() runs, and reports how QEMU died. This improves error reporting to something like /x86_64/device/introspect/list: Broken pipe tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 6 (Aborted) (dumped core) Three exit() remain in libqtest.c: * In qmp_response(), when we can't parse a QMP reply read from the QMP socket. Change to abort() for consistency. * In qtest_qemu_binary(), when QTEST_QEMU_BINARY isn't in the environment. This can only happen before we start QEMU. Leave alone. * In qtest_init_without_qmp_handshake(), when the fork()ed child fails to execlp(). Leave alone. exit() elsewhere are unlikely due to QEMU dying on us. If that should turn out to be wrong, we can move kill_qemu() from @abrt_hooks to atexit() or something.

2018-08-16tests/libqtest: Improve kill_qemu()Eric Blake
In kill_qemu() we have an assert that checks that the QEMU process didn't dump core: assert(!WCOREDUMP(wstatus)); Unfortunately the WCOREDUMP macro here means the resulting message is not very easy to comprehend on at least some systems: ahci-test: tests/libqtest.c:113: kill_qemu: Assertion `!(((__extension__ (((union { __typeof(wstatus) __in; int __i; }) { .__in = (wstatus) }).__i))) & 0x80)' failed. and it doesn't identify what signal the process took. What's more, WCOREDUMP is not reliable - in some cases, setrlimit() coupled with kernel dump settings can result in the flag not being set. It's better to log ALL death by signal, instead of caring whether a core dump was attempted (although once we know a signal happened, also mentioning if a core dump is present can be helpful). Furthermore, we are NOT detecting EINTR (while EINTR shouldn't be happening if we didn't install signal handlers, it's still better to always be robust). Finally, even non-signal death with a non-zero status is suspicious, since qemu's SIGINT handler is supposed to result in exit(0). Instead of using a raw assert, print the information in an easier to understand way: /i386/ahci/sanity: tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 11 (Segmentation fault) (core dumped) (Of course, the really useful information would be why the QEMU process dumped core in the first place, but we don't have that by the time the test program has picked up the exit status.)

Commit b21373d0713 copied wait_command() from tests/migration-test.c to tests/tpm-util.c. Replace both copies by new libqtest helper qtest_qmp_receive_success(). Also use it to simplify qtest_qmp_device_del(). Bonus: gets rid of a non-literal format string. A step towards compile-time format string checking without triggering -Wformat-nonliteral.

2018-08-16tests: Clean up string interpolation around qtest_qmp_device_add()Markus Armbruster
Leaving interpolation into JSON to qmp() is more robust than building QMP input manually, as explained in the commit before previous. qtest_qmp_device_add() and its wrappers interpolate into JSON as follows: * qtest_qmp_device_add() interpolates members into a JSON object. * So do its wrappers qpci_plug_device_test() and usb_test_hotplug(). * usb_test_hotplug() additionally interpolates strings and numbers into JSON strings. Clean them up: * Have qtest_qmp_device_add() take its extra device properties as arguments for qdict_from_jsonf_nofail() instead of a string containing JSON members. * Drop qpci_plug_device_test(), use qtest_qmp_device_add() directly. * Change usb_test_hotplug() parameter @port to string, to avoid interpolation. Interpolate @hcd_id separately. Bonus: gets rid of a non-literal format string. A step towards compile-time format string checking without triggering -Wformat-nonliteral.

2018-08-16tests: Clean up string interpolation into QMP input (simple cases)Markus Armbruster
When you build QMP input manually like this cmd = g_strdup_printf("{ 'execute': 'migrate'," "'arguments': { 'uri': '%s' } }", uri); rsp = qmp(cmd); g_free(cmd); you're responsible for escaping the interpolated values for JSON. Not done here, and therefore works only for sufficiently nice @uri. For instance, if @uri contained a single "'", qobject_from_vjsonf_nofail() would abort. A sufficiently nasty @uri could even inject unwanted members into the arguments object. Leaving interpolation into JSON to qmp() is more robust: rsp = qmp("{ 'execute': 'migrate', 'arguments': { 'uri': %s } }", uri); It's also more concise. Clean up the simple cases where we interpolate exactly a JSON value. Bonus: gets rid of non-literal format strings. A step towards compile-time format string checking without triggering -Wformat-nonliteral.

qtest_qmp_discard_response(...) is shorthand for qobject_unref(qtest_qmp(...), except it's not actually shorter. Moreover, the presence of these functions encourage sloppy testing. Remove them from libqtest. Add them as macros to the tests that use them, with a TODO comment asking for cleanup.

2018-05-04qobject: Replace qobject_incref/QINCREF qobject_decref/QDECREFMarc-André Lureau
Now that we can safely call QOBJECT() on QObject * as well as its subtypes, we can have macros qobject_ref() / qobject_unref() that work everywhere instead of having to use QINCREF() / QDECREF() for QObject and qobject_incref() / qobject_decref() for its subtypes. The replacement is mechanical, except I broke a long line, and added a cast in monitor_qmp_cleanup_req_queue_locked(). Unlike qobject_decref(), qobject_unref() doesn't accept void *. Note that the new macros evaluate their argument exactly once, thus no need to shout them.

Also, rewrite the monitor setup to be generic (using the -qmp shorthand is insufficient for honoring the parameter).
