release-24.2: sql: catch panics in virtual table generators #135966

Open blathers-crl[bot] opened 9 hours ago

Backport 1/1 commits from #135761 on behalf of @yuzefovich.

/cc @cockroachdb/release


This commit improves the stability of CRDB by introducing the panic-catcher into the goroutine that is spun up for generating the contents of the virtual tables. Previously, if the generator function ran into a panic, this would crash the server, and now instead only the query requiring the contents of the vtable will see an error.

Fixes: #135760.

Release note: None


Release justification: low-risk stability improvement.

Thanks for opening a backport.

Please check the backport criteria before merging:

If your backport adds new functionality, please ensure that the following additional criteria are satisfied: - [ ] There is a high priority need for the functionality that cannot wait until the next release and is difficult to address in another way. - [ ] The new functionality is additive-only and only runs for clusters which have specifically “opted in” to it (e.g. by a cluster setting). - [ ] New code is protected by a conditional check that is trivial to verify and ensures that it only runs for opt-in clusters. State changes must be further protected such that nodes running old binaries will not be negatively impacted by the new state (with a mixed version test added). - [ ] The PM and TL on the team that owns the changed code have signed off that the change obeys the above rules. - [ ] Your backport must be accompanied by a post to the appropriate Slack channel (#db-backports-point-releases or #db-backports-XX-X-release) for awareness and discussion.

Also, please add a brief release justification to the body of your PR to justify this backport.
