* | qobject: Change qobject_to_json()'s value to GStringMarkus Armbruster2020-12-191-15/+7Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qobject_to_json() and qobject_to_json_pretty() build a GString, then covert it to QString. Just one of the callers actually needs a QString: qemu_rbd_parse_filename(). A few others need a string they can modify: qmp_send_response(), qga's send_response(), to_json_str(), and qmp_fd_vsend_fds(). The remainder just need a string. Change qobject_to_json() and qobject_to_json_pretty() to return the GString. qemu_rbd_parse_filename() now has to convert to QString. All others save a QString temporary. to_json_str() actually becomes a bit simpler, because GString provides more convenient modification functions.

* | qapi: Use QAPI_LIST_PREPEND() where possibleEric Blake2020-12-194-71/+21Star
|/ | | | | | | | | | | | | | | | | | | | | | | | | Anywhere we create a list of just one item or by prepending items (typically because order doesn't matter), we can use QAPI_LIST_PREPEND(). But places where we must keep the list in order by appending remain open-coded until later patches. Note that as a side effect, this also performs a cleanup of two minor issues in qga/commands-posix.c: the old code was performing new = g_malloc0(sizeof(*ret)); which 1) is confusing because you have to verify whether 'new' and 'ret' are variables with the same type, and 2) would conflict with C++ compilation (not an actual problem for this file, but makes copy-and-paste harder).

* qga: update schema for guest-get-disks 'dependents' fieldMichael Roth2020-11-162-8/+10
| | | | | | | | | | | | | | | | | | | | | | | The recently-added 'guest-get-disk' command returns a list of GuestDiskInfo entries, which in turn have a 'dependents' field which lists devices these entries are dependent upon. Thus, 'dependencies' is a better name for this field. Address this by renaming the field accordingly. Additionally, 'dependents' is specified as non-optional, even though it's not implemented for w32. This is misleading, since it gives users the impression that a particular disk might not have dependencies, when in reality that information is simply not known to the guest agent. Address this by making 'dependents' an optional field, and only marking it as in-use when the facilities to obtain this information are available to the guest agent.

Furthermore, I prefer having unit tests very close to the code, and unit files that are domain specific (commands-posix is too crowded already). FWIW, that coding/testing style is Rust-style (where tests can or should even be part of the documentation!).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. qmp_guest_get_devices() is wrong that way: it calls error_setg() in a loop. If no iteration fails, the function returns a value and sets no error. Okay. If exactly one iteration fails, the function returns a value and sets an error. Wrong. If multiple iterations fail, the function trips error_setv()'s assertion. Fix it to return immediately on error. Perhaps the failure to convert the driver version to UTF-8 should not be an error. We could simply not report the botched version string instead. Drop a superfluous continue while there.

The intent is not so much to report the devices but more importantly the driver (and its version) that is assigned to the device. This gives caller the information whether VirtIO drivers are installed and/or whether inadequate driver is used on a device (e.g. QXL device with base VGA driver). Example: [ { "driver-date": "2019-08-12", "driver-name": "Red Hat VirtIO SCSI controller", "driver-version": "100.80.104.17300", "address": { "type": "pci", "data": { "device-id": 4162, "vendor-id": 6900 } } }, ... ] Signed-off-by: Tomáš Golembiovský <tgolembi@redhat.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> *remove redundant glib autoptr declaration for GuestDeviceInfo Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>

* schemas: Add vim modelineAndrea Bolognani2020-08-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | The various schemas included in QEMU use a JSON-based format which is, however, strictly speaking not valid JSON. As a consequence, when vim tries to apply syntax highlight rules for JSON (as guessed from the file name), the result is an unreadable mess which mostly consist of red markers pointing out supposed errors in, well, pretty much everything. Using Python syntax highlighting produces much better results, and in fact these files already start with specially-formatted comments that instruct Emacs to process them as if they were Python files. This commit adds the equivalent special comments for vim. Signed-off-by: Andrea Bolognani <abologna@redhat.com> Message-Id: <20200729185024.121766-1-abologna@redhat.com> Reviewed-by: Daniel P.

| | | | | | | | | | | | | | | | Problem with g_get_host_name() is that on the first call it saves the hostname into a global variable and from then on, every subsequent call returns the saved hostname. Even if the hostname changes. This doesn't play nicely with guest agent, because if the hostname is acquired before the guest is set up (e.g. on the first boot, or before DHCP) we will report old, invalid hostname.

The "when != lbl:" is necessary to avoid transforming if (fun(args, &err)) { goto out } ... out: error_propagate(errp, err); even though other paths to label out still need the error_propagate(). For an actual example, see sclp_realize(). Without the "when strict", Coccinelle transforms vfio_msix_setup(), incorrectly. I don't know what exactly "when strict" does, only that it helps here. The match of return is narrower than what I want, but I can't figure out how to express "return where the operand doesn't use @err". For an example where it's too narrow, see vfio_intx_enable(). Silently fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Converted manually. Line breaks tidied up manually. One nested declaration of @local_err deleted manually. Preexisting unwanted blank line dropped in hw/riscv/sifive_e.c.

When we have at most one other path that actually needs to propagate, and maybe one at the end that where propagation is unnecessary, e.g. foo(..., &err); if (err) { goto out; } ... bar(..., &err); out: error_propagate(errp, err); return; move the error_propagate() to where it's needed, like if (...) { foo(..., &err); error_propagate(errp, err); return; } ... bar(..., errp); return; and transform the error_setg() as above. In some places, the transformation results in obviously unnecessary error_propagate(). The next few commits will eliminate them. Bonus: the elimination of gotos will make later patches in this series easier to review.
