Slurm 25.5.x compatibility

[martijnkruiten]

This is AI-generated code and might not be correct/complete. It works for our use case and enabled us to upgrade Slurm to 25.05 on our system. I'm opening this merge request to give others the opportunity to see if this works for their use case until official support is added.

Just compiled for debian 12 and slrum 25.05.3 and works as expected for me

I get the following error with my use case (example code):

import pyslurm
desc = pyslurm.JobSubmitDescription(
    time_limit="00:03:00",
    array="1-5",
    qos="standard",
    memory_per_cpu="1",
    script="#!/bin/bash\n sleep ${SLURM_ARRAY_TASK_ID}m")
job_id = desc.submit()

and I get the error:

Traceback (most recent call last):
  File "<python-input-2>", line 1, in <module>
    job_id = desc.submit()
  File "pyslurm/core/job/submission.pyx", line 103, in pyslurm.core.job.submission.JobSubmitDescription.submit

I'll work through this PR within the next couple of days / or rather use it as a starting point (see this comment).

Hey,

going to close this PR, as I've created a separate one with #387 that has a few more/different changes for compatibility.
Thank you again @martijnkruiten for providing a starting point with this PR.

@swalterfub can you try your code-example with the new PR? I just tried it on my test cluster, and it seems to work (on 25.05.3)
