2015-06-22qmp: Wean off qerror_report()Markus Armbruster1-43/+12
The traditional QMP command handler interface int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data); doesn't provide for returning an Error object. Instead, the handler is expected to stash it in the monitor with qerror_report(). When we rebased QMP on top of QAPI, we didn't change this interface. Instead, commit 776574d introduced "middle mode" as a temporary aid for converting existing QMP commands to QAPI one by one. More than three years later, we're still using it. Middle mode has two effects: * Instead of the native input marshallers static void qmp_marshal_input_FOO(QDict *, QObject **, Error **) it generates input marshallers conforming to the traditional QMP command handler interface. * It suppresses generation of code to register them with qmp_register_command() This permits giving them internal linkage. As long as we need qmp-commands.hx, we can't use the registry behind qmp_register_command(), so the latter has to stay for now. The former has to go to get rid of qerror_report(). Changing all QMP commands to fit the QAPI mold in one go was impractical back when we started, but by now there are just a few stragglers left: do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(), qmp_netdev_add(), do_device_add(). Switch middle mode to generate native input marshallers, and adapt the stragglers. Simplifies both the monitor code and the stragglers. Rename do_qmp_capabilities() to qmp_capabilities(), and do_device_add() to qmp_device_add, because that's how QMP command handlers are named today.

These macros expand into error class enumeration constant, comma, string. Unclean. Has been that way since commit 13f59ae. The error class is always ERROR_CLASS_GENERIC_ERROR since the previous commit. Clean up as follows: * Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and delete it from the QERR_ macro.

2015-06-22QemuOpts: Wean off qerror_report_err()Markus Armbruster1-1/+1
qerror_report_err() is a transitional interface to help with converting existing monitor commands to QMP. It should not be used elsewhere. The only remaining user in qemu-option.c is qemu_opts_parse(). Is it used in QMP context? If not, we can simply replace qerror_report_err() by error_report_err(). The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are clearly not in QMP context. The uses in vl.c aren't either, because the only QMP command handlers there are qmp_query_status() and qmp_query_machines(), and they don't call it. Remaining uses: * drive_def(): Command line -drive and such, HMP drive_add and pci_add * hmp_chardev_add(): HMP chardev-add * monitor_parse_command(): HMP core * tmp_config_parse(): Command line -tpmdev * net_host_device_add(): HMP host_net_add * net_client_parse(): Command line -net and -netdev * qemu_global_option(): Command line -global * vnc_parse_func(): Command line -display, -vnc, default display, HMP change, QMP change. Bummer. * qemu_pci_hot_add_nic(): HMP pci_add * usb_net_init(): Command line -usbdevice, HMP usb_add Propagate errors through qemu_opts_parse(). Create a convenience function qemu_opts_parse_noisily() that passes errors to error_report_err(). Switch all non-QMP users outside tests to it. That leaves vnc_parse_func(). Propagate errors through it. Since I'm touching it anyway, rename it to vnc_parse().

2015-05-05qapi: Drop inline nested struct in query-versionEric Blake1-4/+5
A future patch will be using a 'name':{dictionary} entry in the QAPI schema to specify a default value for an optional argument (see previous commit message for more details why); but existing use of inline nested structs conflicts with that goal. This patch fixes one of only two commands relying on nested types, by breaking the nesting into an explicit type; it means that the type is now boxed instead of unboxed in C code, but the QMP wire format is unaffected by this change. Prefer the safer g_new0() while making the conversion.

2012-11-18build: replace weak symbols with a static libraryPaolo Bonzini1-9/+0
Weak symbols were a nice idea, but they turned out not to be a good one. Toolchain support is just too sparse, in particular llvm-gcc is totally broken. This patch uses a surprisingly low-tech approach: a static library. Symbols in a static library are always overridden by symbols in an object file. Furthermore, if you place each function in a separate source file, object files for unused functions will not be taken in. This means that each function can use all the dependencies that it needs (especially QAPI stuff such as error_setg). Thus, all stubs are placed in separate object files and put together in a static library. The library then is linked to all programs.

2012-10-24qmp: handle stop/cont in INMIGRATE statePaolo Bonzini1-6/+11
Right now, stop followed by an incoming migration will let the virtual machine start. cont before an incoming migration instead will fail. This is bad because the actual behavior is not predictable; it is racy with respect to the start of the incoming migration. That's because incoming migration is blocking, and thus will delay the processing of stop/cont until the end of the migration. In addition, there's nothing that really prevents the user from typing the block device's passwords before incoming migration is done, so returning the DeviceEncrypted error is also helpful in the QMP case. Both things can be fixed by just toggling the autostart variable when stop/cont are called in INMIGRATE state. Note that libvirt is currently working around the race by looping if the MigrationExpected answer is returned. After this patch, the command will return right away without ever raising an error.
