Title:
EC2 API errors do not match spec
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
Using code written against the Boto client library and originally tested
against EC2 I'm finding I have to retrofit all my exception handling because
Nova seems to just wrap its own exceptions as EC2ResponseError, so the error
codes have no resemblance to the EC2 API error codes:
http://docs.aws.amazon.com/AWSEC2/latest/APIReference/api-error-codes.html
For example, when I hit Nova quota limits and try to start new
instances I get:
File "/opt/local/nimrodg/share/nimrod/boto/ec2/connection.py", line 715, in
run_instances
verb='POST')
File "/opt/local/nimrodg/share/nimrod/boto/connection.py", line 1000, in
get_object
raise self.ResponseError(response.status, response.reason, body)
EC2ResponseError: EC2ResponseError: 400 Bad Request
<?xml version="1.0"?>
<Response><Errors><Error><Code>TooManyInstances</Code><Message>Quota
exceeded for cores,ram: Request
ed 4, but already used 80 of 80
cores</Message></Error></Errors><RequestID>req-74d2e517-c99f-43e6-bfc
1-651ef79737ff</RequestID></Response>
But I'm expecting the error code for this from an EC2 compatible API to be
InstanceLimitExceeded.
Seems like it should be possible be add the equivalent ec2_api_error
string to all suitable Nova exceptions and then have Nova's EC2 API
use that where available?
