teuthology/suite: pass the base config to scripts #2008

batrick · 2024-10-17T20:01:34Z

This PR is to support: ceph/ceph#60386

Also, this PR fixes a bug: teuthology/tasks/kernel: default branch should be "distro". When the kernel dictionary is empty, the kernel task should assume distro.

Normally, the fs suite overrides the kernel branch whenever the kernel client is used, according to the matrix of configs. This prevents easily testing a new kernel with the -k option to teuthology-suite. So, using the base config passed to the script, detect if an alternate testing kernel is desired and use that instead. The scheduler still needs to do some work: $ teuthology-suite ... -k master --filter k-testing ... 2024-10-17 19:57:52,051.051 DEBUG:teuthology.suite.merge:base kernel {'branch': 'master', 'kdb': 1, 'sha1': 'ccda9910d8490f4fb067131598e4b2e986faa5a0', 'flavor': 'default'} 2024-10-17 19:57:52,051.051 DEBUG:teuthology.suite.merge:overriding testing kernel with {'branch': 'master', 'kdb': 1, 'sha1': 'ccda9910d8490f4fb067131598e4b2e986faa5a0', 'flavor': 'default'} vs. $ teuthology-suite ... --filter k-testing ... 2024-10-17 20:04:52,265.265 DEBUG:teuthology.suite.merge:base kernel {'branch': 'distro', 'kdb': 1, 'sha1': 'distro'} Which will only select jobs using the "testing" kernel.

Nice! I just have one question

zmc · 2024-10-22T18:08:09Z

teuthology/suite/merge.py

    if not isinstance(seed, int):
        log.debug("no valid seed input: using 1")
        seed = 1
    log.debug("configuring Lua randomseed to %d", seed)
    L.execute(f'local math = require"math"; math.randomseed({seed});')
    new_script = L.eval('new_script')
+    base_config_yaml = yaml.safe_load(str(base_config))


It's not immediately obvious why we'd need to create a copy of base_config here and then again on 133 - could you explain the reasoning?

It's to basically enforce a read-only view of the base_config.

I tried to do copy.deepcopy(base_config) below but ran into inscrutable recursion errors that didn't seem worth debugging. So I'm just reloading it as a legit yaml dictionary here.

I think I would suggest just doing a yaml_complete_obj = copy.deepcopy(base_config.to_dict()) on 133 and dropping this statement.

teuthology/suite/merge.py

Presently the code tries to merge the base_config when the worker starts running. There's no need to construct it this way and it prevents sharing the "defaults" with the fragment merging infrastructure. It also prevents overriding defaults like: kernel branch: wip-pdonnell-i66704 client: branch: wip-pdonnell-i66704 flavor: default kdb: 1 sha1: 745cacd8f31e50d7f3b6039bbd8c9a8dfc07bf03 flavor: default kdb: 1 sha1: 745cacd8f31e50d7f3b6039bbd8c9a8dfc07bf03 A YAML fragment can set kernel.client but it cannot delete the defaults for kernel.(branch|flavor|kdb|sha1) because there's no way to remove YAML elements via a deep merge.

Generally, we don't want to install any kernel by default. There also is no "main" branch for the ceph-client.git project. Signed-off-by: Patrick Donnelly <[email protected]>
