Summary of changes

Changes introduced in this pull request:

  • Ports the fix(stmgr): honour GasLimit in StateCall filecoin-project/lotus#13910
  • Now the Filecoin.StateCall honours the gas limit passed to it instead of running uncapped.
  • Adds the env FOREST_STATE_CALL_GAS_LIMIT to pass the gas limit (cap) for the Filecoin.StateCall where a message above the cap is rejected, and one with GasLimit 0 runs at the cap.
  • Updated the existing snapshot for the state call
  • Added devnet tests for the StateCall

Change checklist

  • I have performed a self-review of my own code,
  • I have made corresponding changes to the documentation. All new code adheres to the team's documentation standards,
  • I have added tests that prove my fix is effective or that my feature works (if possible),
  • I have made sure the CHANGELOG is up-to-date. All user-facing changes should be reflected in this document.

Outside contributions

  • This pull request is based on an issue that a maintainer has accepted (see Before Opening a Pull Request).
  • I have read and agree to the CONTRIBUTING document.
  • I have read and agree to the AI Policy document. I understand that failure to comply with the guidelines will lead to rejection of the pull request.

Summary by CodeRabbit

  • Changed

    • Filecoin.StateCall now honors the message’s gas limit. A limit of 0 uses the configured cap; requests above the cap are rejected. The default cap is the block gas limit, and FOREST_STATE_CALL_GAS_LIMIT can set a positive custom cap.
    • State-call gas-limit behavior is compatible with Lotus v1.38.0.
    • Failed messages without FVM failure details now report an unknown error with the return code.
  • New Features

    • Added the forest-dev devnet state-call command to compare state-call results and gas behavior between Forest and Lotus.
  • Documentation

    • Added CLI and environment-variable reference information for the new command and gas-limit setting.

Walkthrough

Forest now applies the requested gas limit to Filecoin.StateCall. A zero limit selects the configured cap, and above-cap requests are rejected. The change adds Forest/Lotus parity tests, shared devnet helpers, API comparison cases, and a fallback error message when failed executions have no FVM failure text.

Changes

StateCall behavior and parity

Layer / File(s) Summary
Resolve StateCall gas limits
src/state_manager/message_simulation.rs, docs/docs/users/reference/env_variables.md, CHANGELOG.md
StateCall uses the message gas limit. A zero limit selects the configured cap; a limit above the cap returns an error. Unit tests and reference text cover these rules.
Share devnet test helpers
src/dev/subcommands/tests_cmd/helpers.rs, src/dev/subcommands/devnet_cmd/eth_gas.rs, src/dev/subcommands/devnet_cmd/eth_skip_sender.rs, src/dev/subcommands/tests_cmd/wallet.rs
Shared helpers provide a cached sender, contract deployment, calldata construction, and test-trial adaptation. Existing devnet and wallet tests use the shared helpers.
Add devnet StateCall parity tests
src/dev/subcommands/devnet_cmd/state_call.rs, src/dev/subcommands/devnet_cmd.rs, scripts/devnet/*, .github/workflows/forest.yml, docs/docs/users/reference/cli.md, docs/docs/users/reference/cli.sh
The new command compares Forest and Lotus StateCall results at a shared tipset, including gas-limit and fee checks. The CLI, integration scripts, workflow, and command reference include the command.
Extend StateCall API comparisons
src/tool/subcommands/api_cmd/api_compare_tests.rs, src/tool/subcommands/api_cmd/test_snapshots.txt, scripts/tests/api_compare/.env
API comparisons add zero-limit and above-block-limit cases. The snapshot list and Lotus calibnet image tag are updated.

Failure reporting

Layer / File(s) Summary
Return fallback failure information
src/shim/executor.rs, CHANGELOG.md
Successful exit codes return no failure information. Failed executions without FVM failure text report unknown error with the exit code.

Merge Risk: ⚪ Minimal · up to 6c3cc

StateCall applies its configured gas cap, and failed calls without FVM text still report an error and return code. No actionable current-head merge risk was established.
