Placeholder Actor Code Cid mismatch #29

Open alexytsu opened 9 months ago

alexytsu commented 9 months ago

When new placeholder actors are created, the VM loads the PLACEHOLDER_ACTOR_CODE_ID from the builtin_actors manifest stored in the DefaultCallManager.

However, when checking this against the expected value (statically generated in the builtin-actors test code) there is a mismatch.

I would guess that it's the test code that needs to change here.

A separate, but related issue is that during evm_eth_create_external_test

Faucet creates EAM by sending to delegated address
Delegated address is created with correct placeholder code cid (matching the stored manifest)
The placeholder actor then makes a call to EAM. At this point, in the FVM it's actor_state.code has changed... (Or become corrupted). In any case, it is no longer the valid placeholder code cid. And therefore message preflight validation checks fail.
