Re: [libvirt] [PATCH v3] hyperv: recognize array property as distinct type.

When hyperv code generator for WMI classes identifies common properties, it needs to take into account array type as a distinct type, i.e string != string[]. This is the case where v1 of the Msvm_VirtualSystemSettingData has Notes property as string whereas v2 uses Notes[], therefore they have to be treated as different fields and cannot be placed in the "common" struct. --- changes in v3: * add virBufferCheckError before calling virBufferContentAndReset. src/hyperv/hyperv_driver.c | 28 ++++++++++++++++++++++++++-- src/hyperv/hyperv_wmi_generator.py | 2 +- 2 files changed, 27 insertions(+), 3 deletions(-) diff --git a/src/hyperv/hyperv_driver.c b/src/hyperv/hyperv_driver.c index 090ea24..8e5eeda 100644 --- a/src/hyperv/hyperv_driver.c +++ b/src/hyperv/hyperv_driver.c @@ -894,8 +894,32 @@ hypervDomainGetXMLDesc(virDomainPtr domain, unsigned int flags) if (VIR_STRDUP(def->name, computerSystem->data.common->ElementName) < 0) goto cleanup; - if (VIR_STRDUP(def->description, virtualSystemSettingData->data.common->Notes) < 0) - goto cleanup; + if (priv->wmiVersion == HYPERV_WMI_VERSION_V1) { + if (VIR_STRDUP(def->description, + virtualSystemSettingData->data.v1->Notes) < 0) + goto cleanup; + } else if (priv->wmiVersion == HYPERV_WMI_VERSION_V2 && + virtualSystemSettingData->data.v2->Notes.data != NULL) { + char **notes = (char **) virtualSystemSettingData->data.v2->Notes.data; + virBuffer buf = VIR_BUFFER_INITIALIZER; + size_t i = 0; + + /* in practice Notes has 1 element */ + for (i = 0; i < virtualSystemSettingData->data.v2->Notes.count; i++) { + /* but if there's more than 1, separate by double new line */ + if (virBufferUse(&buf) > 0) + virBufferAddLit(&buf, "\n\n"); + + virBufferAdd(&buf, *notes, -1); + notes++; + } + + if (virBufferCheckError(&buf)) + cleanup;
