| 43 | /* The purpose of this test is to exercise the case when a |
| 44 | * grpc *security_handshaker* begins its handshake with data already |
| 45 | * in the read buffer of the handshaker arg. This scenario is created by |
| 46 | * adding a fake "readahead" handshaker at the beginning of the server's |
| 47 | * handshaker list, which just reads from the connection and then places |
| 48 | * read bytes into the read buffer of the handshake arg (to be passed down |
| 49 | * to the security_handshaker). This test is meant to protect code relying on |
| 50 | * this functionality that lives outside of this repo. */ |
