'const fooPtr' is the same as 'foo * const' (the pointer won't change, but it's contents can). But in general, if an interface is trying to be const-correct, it should be using 'const foo *' (the pointer is to data that can't be changed). Fix up offenders in src/conf/domain_conf, and their fallout. Several things to note: virObjectLock() requires a non-const argument; if this were C++, we could treat the locking field as 'mutable' and allow locking an otherwise 'const' object, but that is a more invasive change, so I instead dropped attempts to be const-correct on domain lookup. virXMLPropString and friends require a non-const xmlNodePtr - this is because libxml2 is not a const-correct library. We could make the src/util/virxml wrappers cast away const, but I figured it was easier to not try to mark xmlNodePtr as const. Finally, virDomainDeviceDefCopy was a rather hard conversion - it calls virDomainDeviceDefPostParse, which in turn in the xen driver was actually modifying the domain outside of the current device being visited. We should not be adding a device on the first per-device callback, but waiting until after all per-device callbacks are complete. * src/conf/domain_conf.h (virDomainObjListFindByID) (virDomainObjListFindByUUID, virDomainObjListFindByName) (virDomainObjAssignDef, virDomainObjListAdd): Drop attempt at const. (virDomainDeviceDefCopy): Use intended type. (virDomainDeviceDefParse, virDomainDeviceDefPostParseCallback) (virDomainVideoDefaultType, virDomainVideoDefaultRAM) (virDomainChrGetDomainPtrs): Make const-correct. * src/conf/domain_conf.c (virDomainObjListFindByID) (virDomainObjListFindByUUID, virDomainObjListFindByName) (virDomainDeviceDefCopy, virDomainObjListAdd) (virDomainObjAssignDef, virDomainHostdevSubsysUsbDefParseXML) (virDomainHostdevSubsysPciOrigStatesDefParseXML) (virDomainHostdevSubsysPciDefParseXML) (virDomainHostdevSubsysScsiDefParseXML) (virDomainControllerModelTypeFromString) (virDomainTPMDefParseXML, virDomainTimerDefParseXML) (virDomainSoundCodecDefParseXML, virDomainSoundDefParseXML) (virDomainWatchdogDefParseXML, virDomainRNGDefParseXML) (virDomainMemballoonDefParseXML, virDomainNVRAMDefParseXML) (virSysinfoParseXML, virDomainVideoAccelDefParseXML) (virDomainVideoDefParseXML, virDomainHostdevDefParseXML) (virDomainRedirdevDefParseXML) (virDomainRedirFilterUsbDevDefParseXML) (virDomainRedirFilterDefParseXML, virDomainIdMapEntrySort) (virDomainIdmapDefParseXML, virDomainVcpuPinDefParseXML) (virDiskNameToBusDeviceIndex, virDomainDeviceDefCopy) (virDomainVideoDefaultType, virDomainHostdevAssignAddress) (virDomainDeviceDefPostParseInternal, virDomainDeviceDefPostParse) (virDomainChrGetDomainPtrs, virDomainControllerSCSINextUnit) (virDomainSCSIDriveAddressIsUsed) (virDomainDriveAddressIsUsedByDisk) (virDomainDriveAddressIsUsedByHostdev): Fix fallout. * src/openvz/openvz_driver.c (openvzDomainDeviceDefPostParse): Likewise. * src/libxl/libxl_domain.c (libxlDomainDeviceDefPostParse): Likewise. * src/qemu/qemu_domain.c (qemuDomainDeviceDefPostParse) (qemuDomainDefaultNetModel): Likewise. * src/lxc/lxc_domain.c (virLXCDomainDeviceDefPostParse): Likewise. * src/uml/uml_driver.c (umlDomainDeviceDefPostParse): Likewise. * src/xen/xen_driver.c (xenDomainDeviceDefPostParse): Split... (xenDomainDefPostParse): ...since per-device callback is not the time to be adding a device. Signed-off-by: Eric Blake <eblake@redhat.com> |
