[libvirt] [PATCH 08/12] Use virBufferCheckError everywhere we report OOM error

Replace: if (virBufferError(&buf)) { virBufferFreeAndReset(&buf); virReportOOMError(); ... } with: if (virBufferCheckError(&buf) < 0) ... This should not be a functional change (unless some callers misused the virBuffer APIs - a different error would be reported then) --- src/bhyve/bhyve_driver.c | 8 +- src/conf/cpu_conf.c | 6 +- src/conf/domain_conf.c | 17 ++-- src/conf/interface_conf.c | 8 +- src/conf/network_conf.c | 12 +-- src/conf/node_device_conf.c | 9 +- src/conf/nwfilter_conf.c | 16 +--- src/conf/secret_conf.c | 6 +- src/conf/snapshot_conf.c | 5 +- src/conf/storage_conf.c | 18 ++-- src/cpu/cpu_map.c | 14 ++- src/cpu/cpu_x86.c | 5 +- src/esx/esx_driver.c | 12 +-- src/esx/esx_util.c | 12 +-- src/esx/esx_vi.c | 20 ++--- src/esx/esx_vi_methods.c | 4 +- src/hyperv/hyperv_wmi.c | 4 +- src/libxl/libxl_driver.c | 4 +- src/locking/lock_driver_sanlock.c | 5 +- src/lxc/lxc_controller.c | 8 +- src/lxc/lxc_driver.c | 44 +++------ src/network/bridge_driver.c | 8 +- src/node_device/node_device_udev.c | 8 +- src/nwfilter/nwfilter_ebiptables_driver.c | 10 +-- src/nwfilter/nwfilter_gentech_driver.c | 5 +- src/phyp/phyp_driver.c | 10 +-- src/qemu/qemu_command.c | 142 ++++++++---------------------- src/qemu/qemu_driver.c | 44 +++------ src/qemu/qemu_migration.c | 5 +- src/qemu/qemu_monitor.c | 5 +- src/qemu/qemu_monitor_text.c | 9 +- src/rpc/virnetsocket.c | 4 +- src/rpc/virnetsshsession.c | 8 +- src/storage/storage_backend.c | 6 +- src/storage/storage_backend_rbd.c | 6 +- src/uml/uml_conf.c | 4 +- src/util/vircommand.c | 5 +- src/util/virconf.c | 10 +-- src/util/virnetdevopenvswitch.c | 4 +- src/util/virstoragefile.c | 4 +- src/util/virstring.c | 8 +- src/util/virsysinfo.c | 4 +- src/util/virsystemd.c | 8 +- src/util/viruri.c | 5 +- src/vmx/vmx.c | 4 +- src/xen/xen_driver.c | 4 +- src/xen/xend_internal.c | 9 +- src/xenapi/xenapi_utils.c | 5 +- src/xenxs/xen_sxpr.c | 12 +-- src/xenxs/xen_xm.c | 17 +--- tests/domainsnapshotxml2xmltest.c | 4 +- 51 files changed, 158 insertions(+), 456 deletions(-) diff --git a/src/bhyve/bhyve_driver.c b/src/bhyve/bhyve_driver.c index 6c0c8b1..a3b043d 100644 --- a/src/bhyve/bhyve_driver.c +++ b/src/bhyve/bhyve_driver.c @@ -258,10 +258,8 @@ bhyveConnectGetSysinfo(virConnectPtr conn, unsigned int flags) if (virSysinfoFormat(&buf, privconn->hostsysinfo) < 0) return NULL;
