Tracking: TODOs with closed tasks #6281

mpguerra · 2023-03-09T10:53:15Z

Motivation

We want to track all of the findings from the zebra audit.

Details

There are a number of TODOs in the codebase that use task numbers that are already closed. For instance, issue #862 states that the Sync process’s state_contains() API only checks the best chain for a given block hash (zebrad/src/components/sync.rs), rather than checking all the available chains in the mempool. The audited version of the library still queries the best chain in state and the task is closed.

Another example is issue #2214 which suggests that the fanout handling should be done by the PeerSet so that all the fanouts wouldn’t use the same peer and block themselves. This seems to only be an issue on testnet where nodes aren’t as well connected as mainnet and the task is closed. This issue is referenced in a TODO in zebrad/src/components/
sync.rs.

This issue will be used to track any further issues created to address TODOs which refer to issues which have already been closed.

Scope

Write script to find TODOs mentioning closed github issues #6278
Make sync, inbound, and block verifier check if a block hash is in any chain or any queue #862
Evaluate list of TODOs with closed issues and identify:
- which TODOs can be removed because the issue is already closed as done, otherwise resolved, or no longer relevant
- which, if any, issues need to be reopened because they are still relevant and were closed because they were no longer a priority
- which TODOs need to be updated with relevant context
- which TODOs should be updated to WONTFIX in the case the issue was closed as not planned or something that we will not fix.
Update TODO comment referring to Limit fanouts to the number of active peers, Credit: Equilibrium #2214

Evaluate list of TODOs with closed issues and identify:

which TODOs can be removed because the issue is already resolved or no longer relevant

which, if any, issues need to be reopened because they are still relevant

which TODOs need to be updated with relevant context

which TODOs should be updated to WONTFIX

Do we need to have different labels for:

this is something we want to do eventually
this is not something we will ever spend time on, but we will accept volunteer PRs
this is something we don't want to fix, and we won't accept PRs from anyone

I think tickets and TODOs might move between the first two categories as our priorities change, or based on community feedback. But the last category won't change much, because it's usually about an engineering tradeoff where it's too much effort or too risky.

As long as we keep the TODO label that's fine but I wouldn't replace the TODO with another set of labels as this will make it harder to track.

Also I wonder if we're all bikeshedding a bit too much with this one 😅

mpguerra · 2023-05-11T11:56:01Z

Finally started looking into this.

In order for me to track this more easily I have started this spreadsheet and I'll be adding the various different issues reported by the tool and the action to take here.

Once that's done I may create more issues to clean those up as necessary.
