Refactor the function to avoid multiple wrappers splitting identical fields from the now common metadata struct. The refactor is done by folding in the wrapper used for disk sources which allows us to lookup secrets via the secret driver. This may allow using stored secrets for snapshot disk images too in the future. --- src/qemu/qemu_command.c | 122 +++++++++++++++++++++--------------------------- src/qemu/qemu_command.h | 12 ++--- src/qemu/qemu_driver.c | 19 +------- 3 files changed, 58 insertions(+), 95 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 1766a5b..8b4a57a 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -3816,37 +3816,68 @@ qemuBuildNetworkDriveURI(int protocol, int -qemuGetDriveSourceString(int type, - const char *src, - int protocol, - size_t nhosts, - virStorageNetHostDefPtr hosts, - const char *username, - const char *secret, - char **path) +qemuGetDriveSourceString(virStorageSourcePtr src, + virConnectPtr conn, + char **source) { - *path = NULL;
