There was a problem hiding this comment.
This won't work if called from Collectives (para) to the relay chain — but there is an alternative implemented here:
#7592
The fn unbrick function isn't really necessary and could be replaced with two batched calls:
batch(
Paras::authorize_force_set_current_code_hash(new_validation_code),
Paras::force_set_current_head(...)
)
We might just need to add some custom origin validation to force_set_current_head instead of using ensure_root, but that's a very minor change.

Related to RFC-117 (WIP).
This Pull Request aims to implement the pallet components of the Unbrick Collective.
unbrickmethodThe
Paras::unbrickmethod allows a given origin to change the validation code or note a head for a para.This allows paras to opt-in for a delegated origin (i.e.
UnbrickCollective) that can handle operations to unbrick a para.This allows using a single instance of
Whitelistthat executes calls to different origins depending on the caller origin, based on a mapping.Related issues
