Subject: [PATCH 1/2] azure-events: handle exceptions in urlopen The locking in
|
|
|
5371d1 |
azure-events does not correctly handle some failures.
|
|
|
5371d1 |
|
|
|
5371d1 |
If the metadata server is not recheable or has an error
|
|
|
5371d1 |
handling the request, attr_globalPullState will never go
|
|
|
5371d1 |
back to IDLE unless the administrator manually changes it.
