RuntimeError
Exception class to signal any Amazon errors. All errors occuring during calls to Amazon's web services raise this type of error. Attribute inherited by RuntimeError:
message - the text of the error, generally as returned by AWS in its XML response.
# File lib/awsbase/right_awsbase.rb, line 407 def initialize(errors=nil, http_code=nil, request_id=nil) @errors = errors @request_id = request_id @http_code = http_code super(@errors.is_a?(Array) ? @errors.map{|code, msg| "#{code}: #{msg}"}.join("; ") : @errors.to_s) end
Generic handler for AwsErrors. aws is the RightAws::S3, RightAws::EC2, or RightAws::SQS object that caused the exception (it must provide last_request and last_response). Supported boolean options are:
:log print a message into the log using aws.logger to access the Logger
:puts do a "puts" of the error
:raise re-raise the error after logging
# File lib/awsbase/right_awsbase.rb, line 431 def self.on_aws_exception(aws, options={:raise=>true, :log=>true}) # Only log & notify if not user error if !options[:raise] || system_error?($!) error_text = "#{$!.inspect}\n#{$@}.join('\n')}" puts error_text if options[:puts] # Log the error if options[:log] request = aws.last_request ? aws.last_request.path : '-none-' response = aws.last_response ? "#{aws.last_response.code} -- #{aws.last_response.message} -- #{aws.last_response.body}" : '-none-' aws.logger.error error_text aws.logger.error "Request was: #{request}" aws.logger.error "Response was: #{response}" end end raise if options[:raise] # re-raise an exception return nil end
True if e is an AWS system error, i.e. something that is for sure not the caller's fault. Used to force logging.
# File lib/awsbase/right_awsbase.rb, line 451 def self.system_error?(e) !e.is_a?(self) || e.message =~ /InternalError|InsufficientInstanceCapacity|Unavailable/ end
Does any of the error messages include the regexp pattern? Used to determine whether to retry request.
# File lib/awsbase/right_awsbase.rb, line 416 def include?(pattern) if @errors.is_a?(Array) @errors.each{ |code, msg| return true if code =~ pattern } else return true if @errors_str =~ pattern end false end
