* chore: Remove eof trace handlers (paradigmxyz#299)

closes paradigmxyz#298

* chore(`deps`): bump revm to 24.0.0 (paradigmxyz#300)

Bumps Revm to 24.0.0

New releases are out: https://github.com/bluealloy/revm/releases/tag/v74

Required for foundry-rs/foundry#10557

* chore: release 0.23.0

* chore: update deny.toml and upgrade CI workflow (paradigmxyz#302)

Fixes failed `deny` check:
https://github.com/paradigmxyz/revm-inspectors/actions/runs/15468046255/job/43544845990?pr=301

The `deny.toml` / CI was outdated, this should fix it

Inspired by:
https://github.com/alloy-rs/alloy/blob/main/.github/workflows/ci.yml and
https://github.com/alloy-rs/alloy/blob/main/deny.toml

Core of the CI flow is unchanged, only formatted

Removes unused license exceptions as shown by `cargo deny --all-features
check all`

If `git` exceptions are required they can be re-added in the future

* chore: remove EOF leftovers (paradigmxyz#301)

Closes: paradigmxyz#174
(replaces it)

Follow up of paradigmxyz#299

Removes `code_section_idx` that is EOF specific, as added in
paradigmxyz#169

Keeps: `record_immediate_bytes` as I think it may be useful / still used
by Foundry / is more readable.

Undo's missed `ExtDelegateCall` from paradigmxyz#299 :
paradigmxyz#156

* feat: use native BigInt with compatibility layer (paradigmxyz#314)

Uses Boa's native BigInt support instead of relying on the polyfill
while maintaining backward compatibility.

## Changes
- Add BigInt.prototype.toJSON for JSON serialization compatibility
- Create global 'bigint' alias (lowercase) for backward compatibility
- Update to_bigint to use the lowercase bigint alias
- Keep bigint.js polyfill file for potential fallback
- Add comprehensive tests validating native BigInt functionality

## Compatibility
The implementation maintains full backward compatibility:
- The global `bigint` (lowercase) still exists and works as before
- JSON serialization is supported through the added toJSON method
- All existing tests pass without modification

* feat: geth_erc7562_tracers addition (paradigmxyz#316)

* perf: outline edgecov step fn (paradigmxyz#318)

Minimize the impact of `fn step` for the common case of not doing
anything.

* perf: pre alloc struct logs (paradigmxyz#319)

this vec is huge for large txs and for every step we push an entry, so
we can pre-alloc this

* perf: optimize push_steps_on_stack to avoid temporary allocation (paradigmxyz#320)

## Summary

Optimizes the `push_steps_on_stack` method to avoid creating a temporary
vector allocation.

## Changes

The previous implementation would:
1. Call `call_step_stack()` which creates a temporary `Vec`
2. Reverse iterate over that vec and extend the deque

The new implementation:
1. Directly extends the deque with reversed steps (without computing
`call_child_id`)
2. Iterates over the inserted range in reverse to set `call_child_id`
values where needed

* perf: allocate some more initial capacity for CallTraceArena (paradigmxyz#323)

The `vec![]` macro only allocates for the number of elements. In
`CallTraceArena::default()`, it only allocates 1, so when growing it the
capacity doubles starting at 1, which is pretty inefficient.

* fix(geth_tracer): keccak input edge cases (paradigmxyz#328)

smol thing I found while looking at

paradigmxyz/reth#17629

* chore(deps): bump revm 28.0.0, msrv 1.88 required for revm (paradigmxyz#334)

Bumps to revm 28, bumps msrv to 1.88 as it is required for revm

* chore: release 0.28.0

* feat(js): add logic to count current opcode cost instead of cumulative (paradigmxyz#336)

Currently the revm-inspectors js tracer acts differently from the geth
implementation where the `getCost()` function returns the cumulative
amount of cost for each step instead of the individual opcode cost. I
added a simple function that will store the previous spent value and
then use that in the next step to calculate the currect opcode cost.

* feat: add index to log (paradigmxyz#344)

ref alloy-rs/alloy#2748

closes paradigmxyz/reth#17629

* chore: release 0.29.1

* chore: remove debug (paradigmxyz#345)

Default hash builder implements Debug conditionally

* chore: remove clippy.toml (paradigmxyz#346)

MSRV is inferred from Cargo.toml.

* fix(`ci`): feature checks failing due to `std::` use (paradigmxyz#348)

Fixes:
https://github.com/paradigmxyz/revm-inspectors/actions/runs/17609870312/job/50029106190?pr=347

* chore: release 0.29.2

* chore: add `SECURITY.md` (paradigmxyz#347)

Currently missing from the repo

* perf: box CallTraceStep::storage_change (paradigmxyz#352)

Same as paradigmxyz#324, plus
a few nits.

Reduces the size of `CallTraceStep` from 336 to 216 bytes on 64-bit.
This is a gain overall because the vast majority of steps (>=95%) do not
change storage.

* perf: re-use returndata buffer (paradigmxyz#351)

`return_data.buffer()` is `Bytes`. Cheaply clone it instead of creating
a new copy.

* chore: release 0.30.0

* chore: Remove depth and contract fields from CallTraceStep (paradigmxyz#355)

closes paradigmxyz#354

* perf: remove step_stack (paradigmxyz#357)

This stack should always be exactly 1 element, and the context should be
the same in both `step` and `step_end`.

This avoids unnecessary memory bandwidth and `arena` access in case of
`!record` in the very hot `step` functions.

* chore: simplify CallInputExt (paradigmxyz#356)

* chore: rm doc_auto_cfg (paradigmxyz#360)

* Fix return data in geth traces (paradigmxyz#359)

The Geth trace builder incorrectly sets the same `returnData` value for
all opcode steps in a trace,
using the final call output instead of the step-specific return data
buffer state.

## Expected Behavior

Each opcode step should display the return data buffer state
at that specific point in execution.

## Actual Behavior

All opcode steps show the same returnData value - the final output of
the entire
call. 

For example, in a Fibonacci contract call that returns 1, every single
opcode
step shows:
"returnData":
"0x0000000000000000000000000000000000000000000000000000000000000001"

* fix(js-tracer): correctly handle `isPrecompiled` and `slice` builtins (paradigmxyz#363)

Closes paradigmxyz#350
Closes paradigmxyz#349

- Fixes `isPrecompiled` built-in to work correctly. Before we were
incorrectly checking `precompiles_registered` flag which caused the fn
to never be injected. Added test for it as well
- Adds `slice` built-in and a test for it

* fix(js-tracer): more fixes (paradigmxyz#365)

Ref paradigmxyz/reth#18904
Closes paradigmxyz#364

Changes js objects to be created via
`JsObject::with_object_proto(ctx.intrinsics())` instead of
`JsObject::default()` as suggested in
boa-dev/boa#4460 (comment) thus
making sure helpers like `hasOwnProperty` are accessible.

Changes `JsValue -> f64` conversion to happen via `to_numeric_number` so
that bigints can also be used as input values for `slice` functions

* fix: dont include code in post state if disabled (paradigmxyz#366)

closes paradigmxyz/reth#18942

we should not set this if code is disabled in the config

* fix: respect disableCode flag in diff mode for PreStateTracer (paradigmxyz#362)

The disableCode flag was not being respected in diff mode for the
PreStateTracer. When disableCode was set to true, code was correctly
filtered from the pre state but was still appearing in the post state.

This fix ensures that when disableCode is true, the code field is set to
None for both pre and post states in diff mode, matching the expected
behavior from Geth.

Added test coverage to verify the fix works correctly in both cases
(disableCode=true and disableCode=false).
