* qmp: Wean off qerror_report()Markus Armbruster2015-06-221-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* qerror: Clean up QERR_ macros to expand into a single stringMarkus Armbruster2015-06-221-5/+5
| | | | | | | | | | | | | | | | | | | | | 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. No change after preprocessing. * Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into error_setg(...). Again, no change after preprocessing.

* QemuOpts: Wean off qerror_report_err()Markus Armbruster2015-06-221-1/+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().

* monitor: Use traditional command interface for HMP device_addMarkus Armbruster2015-06-021-0/+6
| | | | | | | | | | | | | | | | All QMP commands use the "new" handler interface (mhandler.cmd_new). Most HMP commands still use the traditional interface (mhandler.cmd), but a few use the "new" one. Complicates handle_user_command() for no gain, so I'm converting these to the traditional interface. For device_add, that's easy: just wrap the obvious hmp_device_add() around do_device_add(). monitor_user_noop() is now unused, drop it.

Normalize to hmp_COMMAND(), where COMMAND is exactly the command name with '-' replaced by '_'. Exceptions: * do_device_add() and client_migrate_info() *not* renamed to hmp_device_add(), hmp_client_migrate_info(), because they're also QMP handlers. They still need to be converted to QAPI. * do_memory_dump(), do_physical_memory_dump(), do_ioport_read(), do_ioport_write() renamed do hmp_* instead of hmp_x(), hmp_xp(), hmp_i(), hmp_o(), because those names are too cryptic for my taste. * do_info_help() renamed to hmp_info_help() instead of hmp_info(), because it only covers help.

* / qemu-io: Use BlockBackendMax Reitz2015-02-161-4/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | qemu-io should behave like a guest, therefore it should use BlockBackend to access the block layer. There are a couple of places where that is infeasible: First, the bdrv_debug_* functions could theoretically be mirrored in the BlockBackend, but since these are functions internal to the block layer, they should not be visible externally (qemu-io as a test tool is exempt from this). Second, bdrv_get_info() and bdrv_get_specific_info() work on a single BDS alone, therefore they should stay BDS-specific. Third, bdrv_is_allocated() mainly works on a single BDS as well. Some data may be passed through from the BDS's file (if sectors which are apparently allocated in the file are not really allocated there but just zero). [Fixed conflicts around block_acct_start() usage from Fam Zheng's "qemu-io: Account IO by aio_read and aio_write" commit. Use BlockBackend and blk_get_stats() instead of BlockDriverState. --Stefan] Signed-off-by: Max Reitz <mreitz@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-id: 1423162705-32065-14-git-send-email-mreitz@redhat.com Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

* block: add backing-file option to block-streamJeff Cody2014-07-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some image chains, QEMU may not always be able to resolve the filenames properly, when updating the backing file of an image after a block job. For instance, certain relative pathnames may fail, or drives may have been specified originally by file descriptor (e.g. /dev/fd/???), or a relative protocol pathname may have been used. In these instances, QEMU may lack the information to be able to make the correct choice, but the user or management layer most likely does have that knowledge. With this extension to the block-stream api, the user is able to change the backing file of the active layer as part of the block-stream operation. This allows the change to be 'safe', in the sense that if the attempt to write the active image metadata fails, then the block-stream operation returns failure, without disrupting the guest. If a backing file string is not specified in the command, the backing file string to use is determined in the same manner as it was previously.
