Work Description: Abacn commented on PR #17728:
URL: https://github.com/apache/beam/pull/17728#issuecomment-1135972858
This was a bug of cython Shadow fixed in upcoming v3.0
(https://github.com/cython/cython/commit/3149eb8367e69f1558c73b0ebc266bdfba8abc0d).
Before cython 3.0 is released this patch looks needed.
In the translated c-code the helper function gives
```
/* "apache_beam/runners/worker/operations.py":95
*
* def _cast_to_operation(value):
* if cython.compiled: # <<<<<<<<<<<<<<
* return cython.cast(Operation, value)
* else:
*/
__pyx_t_1 = (1 != 0);
if (__pyx_t_1) {
...
goto __pyx_L0;
/* ... */
}
/* ... */
/*else*/ {
...
goto __pyx_L0;
}
/* ... */
/* function exit code */
...
__pyx_L0:;
...
return __pyx_r;
}
```
where the branching condition is constant in the compile time and should be
eliminated by c compiler.
