aaedf32c04 fix(test/remove_node_test.go) fix a deadlock in the test 
The go-etcd client waits for the response from the paused node. And the test waits for the reponse to continue.
Actually we do not even need that small test, since we will check the machine status afterwards.

04f21b5976 Merge pull request #569 from unihorn/5 
Ordering and functionality of `-discovery` `-peers` and data dir to find peers
 2014-02-17 14:34:53 -08:00
Yicheng Qin
3a4df1612c feat(discovery): adjust boot order to find peers 
The boot order for peers is -discovery, -peers, log data, forming
new cluster itself.

Special rules:
1. If discovery succeeds, it would find peers specified by discover URL
only.
2. Etcd would fail when meeting bad -discovery, no -peers and log data.

Add TestDiscoveryDownNoBackupPeersWithDataDir as the test.

bd56b15b6e fix(tests/discovery): use host as -peers parameter instead of url 
Or it cannot test the functionality correctly.
Moreover, add TestDiscoveryNoWithBackupPeers as the test for it.
