THRIFT-4010 Q.fcall messing up with *this* pointer inside called funcâ¦
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.
