select * from non-existent measurement can panic database

[biskit]

just use a database and give name of unknown table. crashes server. basic test!

[abc influxdb]$ ./influx
Connected to http://localhost:8086 version FIXME
InfluxDB shell 0.9.0
> show databases

collectd

> use collectd
Using database collectd

@biskit Yes, as it turns out, if you ask the database to do something nonsensical, such as return the results from a measurement than doesn't exist, it fails. In this case it should fail more gracefully, but there is a 0 in front of the version number, meaning this is beta software. Considering what you paid for the database I think your snark is rude and is most certainly unappreciated.

I cannot reproduce this on my machine. I'm using 0.9.0 installed via Homebrew on OS X (Yosemite)

> show databases
name: databases
---------------
name
mydb
mydb1
mydb3

> use mydb3
Using database mydb3
> select * from does_not_exist
ERR: measurement not found: "mydb3"."default".does_not_exist

No crash, the process is still up and running.

@biskit what OS are you running and how did you install InfluxDB?

I believe this has been fixed for 0.9.1.

Tested against master.

{
    "results": [
        {
            "error": "measurement not found: \"foo\"..cpu"
        }
    ]
}
