STINNER Victor <victor.stinner at gmail.com> added the comment:
I wrote a new "_PyInitError" type to report more information when something goes wrong:
* indicate if it's an user error: don't abort() in that case
* function name where the error was raised
* error message
Example:
---
$ PYTHONHASHSEED=x ./python
Fatal Python error: _Py_HashRandomization_Init: PYTHONHASHSEED must be "random" or an integer in range [0; 4294967295]
---
=> Python doesn't fail with abort() anymore
=> notice the new "_Py_HashRandomization_Init" function name which gives context to the error message
Previously, Python called abort() and so might dump a core file:
---
$ PYTHONHASHSEED=x python3
Fatal Python error: PYTHONHASHSEED must be "random" or an integer in range [0; 4294967295]
Aborted (core dumped)
