* Improve the correctness of Eth's trace_block
- Improve encoding/decoding of parameters and return values:
- Encode "native" parameters and return values with Solidity ABI.
- Correctly decode parameters to "create" calls.
- Use the correct (ish) output for "create" calls.
- Handle all forms of "create".
- Make robust with respect to reverts:
- Use the actor ID/address from the trace instead of looking it up in
the state-tree (may not exist in the state-tree due to a revert).
- Gracefully handle failed actor/contract creation.
- Improve performance:
- We avoid looking anything up in the state-tree when translating the
trace, which should significantly improve performance.
- Improve code readability:
- Remove all "backtracking" logic.
- Use an "environment" struct to store temporary state instead of
attaching it to the trace.
- Fix random bugs:
- Fix an allocation bug in the "address" logic (need to set the
capacity before modifying the slice).
- Improved error checking/handling.
- Use correct types for `trace_block` action/results (create, call, etc.).
- And use the correct types for Result/Action structs instead of reusing the same "Call" action every time.
- Improve error messages.
This will re-execute tipsets to forcibly re-compute and store events
when they're missing. This is effectively lazy backfilling of events.
NOTE: This _won't_ backfill the index itself, it'll just give us the
events.
fixes#11335
We need to always use the state-tree from the tipset _after_ the message
executed. If we use any other state-tree, we might not find the address
we're trying to resolve.
This change also has some implication for pending messages: there's no
guarantee we'll be able to generate a 0x-style address for a pending
native message. So, instead of trying, I've removed support for pending
native messages from the Eth API. Messages from EthAccounts will still
work, and native messages will still show up in blocks/traces, they just
won't show up as "pending". Which should affect exactly nobody.
I'm also taking this opportunity to cleanup some edge-cases:
1. Pass contexts where appropriate.
2. Remove all state access from `ethTxHashFromSignedMessage`.
Part of #11355
We added this check as a self-test to make sure that the message indices
in our trace matched up with those in the block. Unfortunately, this
only works for blocks on the main-chain, and breaks tracing of uncle
blocks (and tracing of head).
* chore: eth: move & rename input/output encoding functions
These are shared functions, so I'm moving them to the utils library.
* fix: eth: correctly encode and simplify native input/output encoding
When generating eth traces, we encode "native" message inputs/outputs
to "solidity ABI" by formatting the inputs/outputs the same way we do in
FEVM's "handle_native_method". However, we had quite a few bugs with the
implementation:
1. We were right-aligning 64bit values in 256bit words, instead of
left-aligning (as we should given that these values are big-endian).
2. The return-value encoding wasn't correctly handling lengths.
This patch:
1. Fixes those bugs.
2. Deduplicates the logic (we're doing _basically_ the same thing in
both cases).
3. Removes all error paths (these functions can't fail).
We were computing this based on the max block gas, but this is
incorrect. The new value isn't entirely correct either (we should
probably compute an average of the gas used in each block in the
tipset?), but it's good enough.
fixes#10515
All these cases here are actually errors and returning `nil` makes this
hard to debug. We likely returned nil in the past to be "best effort"
but, as far as I can tell, we should only hit these error cases if
something is actually wrong.
part of #11325
After changing in prev commit to use to ethereum addresses the
comparison does not make sense against builtin actors. This
fixes that by storing also the filecoin addresses in each trace
Also renamed filecoin related fields to Filecoin prefix.
Also remove requirement call to InvokeContract needed to come
from a evm actor
Fixes: #10814
This PR updates the following RPC methods according to EIP-1898
specs.
The following RPC methods are affected:
- eth_getBalance
- eth_getStorageAt
- eth_getTransactionCount
- eth_getCode
- eth_call
Note that eth_getBlockByNumber was not included in this list in
the spec although it seems it should be affected also?
Currently these methods all accept a blkParam string which can be
one of "latest", "earliest", "pending", or a block number (decimal
or hex). The spec enables caller to additionally specify a json
hash which can include the following fields:
- blockNumber EthUint64: A block number (decimal or hex) which is
similar to the original use of the blkParam string
- blockHash EthHash: The block hash
- requireCanonical bool) If true we should make sure the block is
in the canonical chain
Since the blkParam needs to support both being a number/string and
a json hash then this to properly work we need to introduce a new
struct with pointer fields to check if they exist. This is done
in the EthBlockParamByNumberOrHash struct which first tries to
unmarshal as a json hash (according to eip-1898) and then fallback
to unmarshal as string/number.
* have gas estimate call callInternal with applyTsMessages = false and other calls with applyTsMessages=true for gas caclulation optimization
* set applyTsMessages = true in CallWithGas call in shed
* update test with new callwithgas api optimization for eth call
* Update chain/stmgr/call.go

* env flag LOTUS_SKIP_APPLY_TS_MESSAGE_CALL_WITH_GAS must be 1 in order to have applyTsMessages change
* env flag LOTUS_SKIP_APPLY_TS_MESSAGE_CALL_WITH_GAS must be 1 in order to have applyTsMessages change
* make sure that even if we arent apply ts messages we grab ts messages from the particular user who is requesting gas estimation

This change:
1. Introduces new "limited" API endpoints for EthGetTransactionByHash
and EthGetTransactionReceipt that accept lookback-limits.
2. Implements the gateway version of these API endpoints by calling the
limited variants with the default message search lookback limit.
fixes#10412
Instead:
1. Use the receipt from the message search.
2. Re-compute the gas fees that would have been charged.
fixes#10418

After transitioning from using StateCompute to loading receipts,
we can no longer handle the 'pending' block without forcing
computation. Eth Core Devs are evaluating a proposal to remove
support on their end too.
