* accpet connection object and stream flag as parameter in __init__ remove connect function for connction is given in as parameter. * remove newStream() from each function create new stream object in __init__. function also need flags parameter. * Add 5 new functions screenshot(self, domain, screen, flags = 0) download(self, vol, offset, length, flags = 0) upload(self, vol, offset, length, flags = 0) recvAll(self, handler, opaque) sendAll(self, handler, opaque) for recvAll and sendAll, handler is a user defined function which write/read data to/from file. --- lib/streamAPI.py | 75 ++++++++++++++++++++++++++++++++++++------------------ 1 files changed, 50 insertions(+), 25 deletions(-) diff --git a/lib/streamAPI.py b/lib/streamAPI.py index bc7d217..4da57ca 100644 --- a/lib/streamAPI.py +++ b/lib/streamAPI.py @@ -38,76 +38,101 @@ append_path(result.group(0)) import exception class StreamAPI(object): - def __init__(self, connection): + def __init__(self, connection, flag = 0): self.conn = connection + self.stream_obj = self.conn.newStream(flag) - def abort(self, flag = 0): + def abort(self): try: - stream_obj = newStream(flag) - return stream_obj.abort() + return self.stream_obj.abort() except libvirt.libvirtError, e: message = e.get_error_message() code = e.get_error_code() raise exception.LibvirtAPI(message, code) - def connect(self, flag = 0): + def finish(self): try: - stream_obj = newStream(flag) - return stream_obj.connect() + return self.stream_obj.finish() except libvirt.libvirtError, e: message = e.get_error_message() code = e.get_error_code() raise exception.LibvirtAPI(message, code) - def finish(self, flag = 0): + def recv(self, nbytes): try: - stream_obj = newStream(flag) - return stream_obj.finish() + return self.stream_obj.recv(nbytes) except libvirt.libvirtError, e: message = e.get_error_message() code = e.get_error_code() raise exception.LibvirtAPI(message, code) - def recv(self, flag = 0, data, nbytes): + def send(self, data): try: - stream_obj = newStream(flag) - return stream_obj.recv(data, nbytes) + return self.stream_obj.send(data) except libvirt.libvirtError, e: message = e.get_error_message() code = e.get_error_code() raise exception.LibvirtAPI(message, code) - def send(self, flag = 0, data, nbytes): + def eventAddCallback(self, cb, opaque): try: - stream_obj = newStream(flag) - return stream_obj.send(data, nbytes) + return self.stream_obj.eventAddCallback(cb, opaque) except libvirt.libvirtError, e: message = e.get_error_message() code = e.get_error_code() raise exception.LibvirtAPI(message, code) - def eventAddCallback(self, flag = 0, cb, opaque): + def eventRemoveCallback(self): try: - stream_obj = newStream(flag) - return stream_obj.eventAddCallback(cb, opaque) + return self.stream_obj.eventRemoveCallback() except libvirt.libvirtError, e: message = e.get_error_message() code = e.get_error_code() raise exception.LibvirtAPI(message, code) - def eventRemoveCallback(self, flag = 0): + def eventUpdateCallback(self, events): try: - stream_obj = newStream(flag) - return stream_obj.eventRemoveCallback() + return self.stream_obj.eventUpdateCallback(events) except libvirt.libvirtError, e: message = e.get_error_message() code = e.get_error_code() raise exception.LibvirtAPI(message, code) - def eventUpdateCallback(self, flag = 0, events) + def screenshot(self, domain, screen, flags = 0): try: - stream_obj = newStream(flag) - return stream_obj.eventUpdateCallback(events) + return self.stream_obj.screenshot(domain, screen, flags) + except libvirt.libvirtError, e: + message = e.get_error_message() + code = e.get_error_code() + raise exception.LibvirtAPI(message, code) + + def download(self, vol, offset, length, flags = 0): + try: + return self.stream_obj.download(vol, offset, length, flags) + except libvirt.libvirtError, e: + message = e.get_error_message() + code = e.get_error_code() + raise exception.LibvirtAPI(message, code) + + def upload(self, vol, offset, length, flags = 0): + try: + return self.stream_obj.upload(vol, offset, length, flags) + except libvirt.libvirtError, e: + message = e.get_error_message() + code = e.get_error_code() + raise exception.LibvirtAPI(message, code) + + def recvAll(self, handler, opaque): + try: + return self.stream_obj.recvAll(handler, opaque) + except libvirt.libvirtError, e: + message = e.get_error_message() + code = e.get_error_code() + raise exception.LibvirtAPI(message, code) + + def sendAll(self, handler, opaque): + try: + return self.stream_obj.sendAll(handler, opaque) except libvirt.libvirtError, e: message = e.get_error_message() code = e.get_error_code()
