[libvirt] [test-API][PATCH 1/2] Declare hypervisor connection variable as the global

The is solve the problem where the failure of open() will lead to null conn variable, and when we call close() later,it will report no global 'conn' attribute to the ConnectAPI object. remove a duplicated close() function --- lib/connectAPI.py | 19 ++++++------------- 1 files changed, 6 insertions(+), 13 deletions(-) diff --git a/lib/connectAPI.py b/lib/connectAPI.py index 5d5b94f..702a088 100644 --- a/lib/connectAPI.py +++ b/lib/connectAPI.py @@ -40,11 +40,11 @@ import exception class ConnectAPI(object): def __init__(self): - pass + self.conn = None def open(self, uri): try: - self.conn = libvirt.open(uri) + conn = libvirt.open(uri) return self.conn except libvirt.libvirtError, e: message = e.get_error_message() @@ -53,7 +53,7 @@ class ConnectAPI(object): def open_read_only(self, uri): try: - self.conn = libvirt.openReadOnly(uri) + conn = libvirt.openReadOnly(uri) return self.conn except libvirt.libvirtError, e: message = e.get_error_message() @@ -62,21 +62,13 @@ class ConnectAPI(object): def openAuth(self, uri, auth, flags = 0): try: - self.conn = libvirt.openAuth(uri, auth, flags) + conn = libvirt.openAuth(uri, auth, flags) return self.conn except libvirt.libvirtError, e: message = e.get_error_message() code = e.get_error_code() raise exception.LibvirtAPI(message, code) - def close(self): - try: - self.conn.close() - except libvirt.libvirtError, e: - message = e.get_error_message() - code = e.get_error_code() - raise exception.LibvirtAPI(message, code) - def get_caps(self): try: caps = self.conn.getCapabilities() @@ -398,7 +390,8 @@ class ConnectAPI(object): def close(self): try: - return self.conn.close() + if self.conn: + return self.conn.close() except libvirt.libvirtError, e: message = e.get_error_message() code = e.get_error_code() -- 1.7.1
