Dear all,
I am writing a SPANK plugin to propagate several environment variables
to `Prolog` and `Epilog` scripts but, so far, we have only managed to do
so successfully for the former.
In our SPANK plugin we capture some information from the user using
additional CLI flags and then export this information as environment
variables in `slurm_spank_local_user_init()`:
```
int
slurm_spank_local_user_init(spank_t sp, int ac, char** av) {
// ...
// set some internal env vars required by the job's prolog/epilog
if(spank_job_control_setenv(sp, "FOOBAR", "foobar", 1) !=
ESPANK_SUCCESS) {
slurm_spank_log("failed to set FOOBAR env var");
return -1;
}
/// ...
}
```
This works fine for the Prolog script (calling `env` from the scripts
correctly reports a `SPANK_FOOBAR` environment variable with the
appropriate value), but surprisingly doesn't work for the Epilog script,
though the documentation in https://slurm.schedmd.com/spank.html implies
otherwise.
Is this a bug or am I missing something?
Many thanks in advance.
cheers,
alberto
