-----------------------------------
Summary: Fix Lua compiler omitting default values in Lua service
functions
Key: THRIFT-5417
URL: https://issues.apache.org/jira/browse/THRIFT-5417
Project: Thrift
Issue Type: Bug
Components: Lua - Compiler
Affects Versions: 0.13.0
Reporter: Jeffrey Han
Add missing default argument values for service client functions in generated
Lua code.
*Example Thrift definition:*
{{const string kTestStr = "0"}}
{{service SomeService {}}
{{ void someMethod(1: string a, 2: string b = kTestStr)}}
{{ throws (1: SomeError error)}}
{{}}}
*Generated code before:*
{{function SomeServiceClient:send_someMethod(a, b)}}
{{ self.oprot:writeMessageBegin('someMethod', TMessageType.CALL, self._seqid)}}
{{ local args = someMethod_args:new{}}}
{{ args.a = a}}
{{ args.b = b}}
{{ args:write(self.oprot)}}
{{ self.oprot:writeMessageEnd()}}
{{ self.oprot.trans:flush()}}
{{end}}
*Generated code after:*
{{function SomeServiceClient:send_someMethod(a, b)}}
{{ self.oprot:writeMessageBegin('someMethod', TMessageType.CALL, self._seqid)}}
{{ local args = someMethod_args:new{}}}
{{ args.a = a}}
{{ if b ~= nil then}}
{{ args.b = b}}
{{ else}}
{{ args.b = '0'}}
{{ end}}
{{ args:write(self.oprot)}}
{{ self.oprot:writeMessageEnd()}}
{{ self.oprot.trans:flush()}}
{{end}}
