-------------------------------------
Summary: Q.fcall messing up with *this* pointer inside called
function
Key: THRIFT-4010
URL: https://issues.apache.org/jira/browse/THRIFT-4010
Project: Thrift
Issue Type: Bug
Components: Node.js - Compiler
Affects Versions: 0.9.3
Reporter: Bruno Fonseca
Fix For: 0.10.0
Example: I define a basic service
```
namespace js Auth
service AuthSrv {
string signin(
1:string email,
2:string password
)
}
```
And set up a Auth es6 class that gonna handle the requests like this:
```
module.exports = class AuthSrv {
constructor() {
this.db = .........
}
async signin(email, password) {
try {
let user = await this.db.findOne(....)
}
....
}
}
```
and instantiate a thrift server like this:
```
let server = thrift.createServer(AuthProcessor, new AuthSrv());
```
In this scenario, i'm getting that *this* pointer is **undefined** when signin
function is called. Looking at thrift generated code for the processor i saw
this line:
```
if (this._handler.signin.length === 2) {
Q.fcall(this._handler.signin, args.email, args.password)
.then(.....)
}
```
If i change the fcall to:
```
if (this._handler.signin.length === 2) {
Q.fcall(this._handler.signin.bind(this._handler), args.email, args.password)
.then(.....)
}
```
everything works like a charm and *this* pointer is correctly assinged inside
signin function call.
