Description Michal Linhard 2010-11-17 12:17:12 UTC 
project_key: EDG

The text protocol processing logic regarding delete command doesn't allow for command pipelining:

$ echo -e "delete a\r\ndelete a\r" | nc localhost 11211
CLIENT_ERROR org.infinispan.server.core.ServerException: java.io.StreamCorruptedException: Unable to parse noreply optional argument

the logic is as follows

1. read header "delete "
2. read key "a\r\n"
3. read parameters READS ERRONEOUSLY NEXT COMMAND: "delete a\r\n"

when sending one command only this is ok
$ echo -e "delete a\r" | nc localhost 11211
NOT_FOUND

because read parameters in step 3 just returns line ""
but makes trouble when delete command appears in the middle of the command input stream.
