allow property aliases in redpanda.yaml, fix aliases not being applied #15605

andijcr · 2023-12-14T17:22:52Z

Property aliases are not included in the ignored items when reading a node yaml config or cluster yaml config.

This pr fixes 3 distinct but related bugs:

aliases not being being applied

solved with the first commit. when searching for a property with an alias, do not skip applying the value

aliases in bootstrapping redpanda.yaml causing std::illegal_argument exceptions

with commit 4-5 include aliases in the list of names to be ignored when setting node config

~~3. properties set with aliases reverting to a previous value after a restart, under some conditions.~~
~~- with commit 6 translate aliases to the main name before applying it to the controller log. this is more a workaround than a proper fix of the underlying issue, as described in #13362~~

edit: #15725 should be a proper fix for #13362. so the third commit is no longer necessary. once that merge, this can merge on top

Fixes #15603

Backports Required

Bug Fixes

cluster config aliases are accepted while reading from yaml

config_store bug about not considering aliases for bootstrap

please describe the problem that is fixed in this commit, and how it is fixed. it also looks like there is some code moved / refactored? if so, that could be a separate commit to make it easier to understand the change.

done, splitted it apart. the first commit has the first fix, the following are some cosmetic change to bring it up smoothly at this stage

dotnwat

what test(s) should we add?

andijcr · 2023-12-15T18:30:26Z

what test(s) should we add?

e132fa0

and another where we trigger the invalid argument check.

in cluster_config_test.py

e132fa0
and another where we trigger the invalid argument check.

As far as I can tell the issue linked to in this PR doesn't mention any failing tests. So maybe it's changing / fixing some behavior? If so, that would qualify for a test or update to a test?

andrwng

The changes look good, but will wait on a test to approve. It'd be great to at least cover the behavior in the issue, where delete_retention_ms is set in the config

src/v/config/config_store.h

before this commit, finding the name in the alias table would not throw the std::invalid_argument exception. but would not set the property.

this is a non-functional change

non functional change, the optional was just used inside a code block

property_aliases() mirrors property_names() and both get merged in property_names_and_aliases(), to be used instead of property_names when filtering/scanning over user input

this allows to include prop aliases when validating external input

andijcr · 2023-12-15T23:11:38Z

the last commit address issue #15263 and #13362
by converting aliases to the primary name before writing them to the log.

it's a partial solution, because if the cluster is in the middle of an upgrade, the conversion is skipped (and this in not strictly required. we could save the version when an alias is introduced, to skip conversion only for the latest)

andrwng

The first few commits lgtm, but I've got some questions about the last one.

Still would be great to have a test for the functional changes

src/v/cluster/config_frontend.cc

andijcr · 2023-12-18T17:09:17Z

force push: removed last commit, the issue was solved with #15725

andrwng

I think these changes look good. Would be great to have some tests

src/v/config/config_store.h

andrwng

Thanks for adding some tests! There is probably more to be done, e.g. in ducktape tests, but I don't think that has to block this
