Nick Lanham updated THRIFT-370:
-------------------------------
Attachment: issetTest.tar.gz
sample server/client for this problem. to use do:
$ tar -xzvf issetTest.tar.gz
$ cd isset_case
$ thrift --gen cpp isset.thrift
$ make
$ ./issetServer
and then run
$ ./issetClient
from another window and observe the output.
nothing should be set, but everything is.
> unset fields in structs in c++ have __isset set to true

> Key: THRIFT-370
> URL: https://issues.apache.org/jira/browse/THRIFT-370
> Project: Thrift
> Issue Type: Bug
> Components: Library (C++)
> Affects Versions: 0.1
> Environment: Linux 2.6.27-11 x86_64
> Reporter: Nick Lanham
> Fix For: 0.1
>
> Attachments: issetTest.tar.gz

>
> If you have a struct like:
> struct test_struct {
> 1:string test_string
> }
> and then in a c++ client you do:
> test_struct foo;
> client.someFunc(foo)
> then the server will see it's argument (arg) as having
> arg.__isset.test_string set to true.
> similarly from the client side if expect a return value and do:
> test_struct returnVal;
> client.someFunc(returnVal);
> and the server does not set the returnVal to anything it will still see
> returnVal.__isset.test_string as true
> in all cases the string *is* set to the empty string as the constuctor for
> test_struct sets it, but __isset should not be true.
> Attached (should be) a simple test case. Just untar run "thrift --gen cpp
> isset.thrift" and then run make. start up the server and run the client to
> see the output.
