It has been protected to require PRs, which are automatically generated by the workflow introduced in this PR. The new workflow is designed to be manually dispatched with an input string of the commit hash to use as a source for renaming. On dispatch, it: 1. Checks out the source commit; 2. Renames the module; 3. Makes all necessary internal changes (e.g. import renaming); 4. Runs [smoke tests](https://en.wikipedia.org/wiki/Smoke_testing_(software)); 5. Commits the changes to a new branch; and 6. Opens a PR to merge the new branch into `renamed-go-module`. ### Intended usage When performing an upstream sync to pull in new geth code, this workflow will first be run against the geth commit we intend to merge. After the generated PR is merged, the `renamed-go-module` branch will be the one incorporated into `main`. Note that the `renamed-go-module` branch requires _two_ reviewers to approve. The user who dispatches the workflow SHOULD be one, with any other valid reviewer as the other. This is because a single-reviewer workflow would allow any user to update the `renamed-go-module` branch because the PR author is `github-actions`. ## How this was tested Inspection of the generated PR #57 as well as the [workflow run that generated it](https://github.com/ava-labs/libevm/actions/runs/11298471240/job/31427495426). --- .github/workflows/rename-module.yml | 81 +++++++++++++++++++++++++++++ 1 file changed, 81 insertions(+) create mode 100644 .github/workflows/rename-module.yml diff --git a/.github/workflows/rename-module.yml b/.github/workflows/rename-module.yml new file mode 100644 index 00000000000..a197cca7ab6 --- /dev/null +++ b/.github/workflows/rename-module.yml @@ -0,0 +1,81 @@ +name: Rename Go module + +on: + # During development, the next two lines MAY be enabled to have the PR + # automatically run this workflow for inspection of the resulting branch. + # However, they MUST be disabled again before merging otherwise *all* PRs will + # run this. + # + # pull_request: + # branches: [ main ] + workflow_dispatch: + inputs: + source_commit: + description: 'Upstream commit on which to base module renaming' + required: true + type: string + default: '2bd6bd01d2e8561dd7fc21b631f4a34ac16627a1' + +jobs: + rename-module: + runs-on: ubuntu-latest + env: + source_commit: "${{ inputs.source_commit || '2bd6bd01d2e8561dd7fc21b631f4a34ac16627a1' }}" + # env variables cannot reference others so we have to duplicate the || + output_branch: "${{ github.ref_name }}_auto-rename-module-${{ inputs.source_commit || '2bd6bd01d2e8561dd7fc21b631f4a34ac16627a1' }}" + steps: + - uses: actions/checkout@v4 + with: + fetch-depth: 0 # everything + fetch-tags: true + + - name: Check out source commit + run: git checkout ${{ env.source_commit }} + + - name: Globally update module name + run: | + go mod edit -module github.com/ava-labs/libevm; + find . -iname '*.go' -o -iname '*.txt' | xargs sed -i -E \ + 's|(["`]github\.com/)ethereum/go-ethereum|\1ava-labs/libevm|g'; + + - name: Remnant references + run: | + find . -type f | \ + xargs grep -In github.com/ethereum/go-ethereum | \ + grep -v "https://github.com/ethereum/go-ethereum" + + - name: Set up Go + uses: actions/setup-go@v5 + with: + go-version: 1.21.4 + + - name: Smoke tests + # `go list` shows us the module name and grep will non-zero exit on mismatch + # `go build` is a rudimentary but broad test of correctness + # The explicitly tested packages are edge cases: + # - bind generates tests and a go.mod on the fly + # - rlpgen has testdata with imports that need updating + run: | + go list . | grep ava-labs/libevm; + go build ./...; + go test ./accounts/abi/bind ./rlp/rlpgen + + - name: Commit to new branch + uses: devops-infra/action-commit-push@8bc2ff9f9de7aa2a7581fc7e5b6401c04cab54c7 + with: + github_token: ${{ secrets.GITHUB_TOKEN }} + target_branch: ${{ env.output_branch }} + force: true + commit_prefix: "[AUTO] rename Go module + update internal import paths" + + - name: Open PR to "renamed-go-module" iff workflow dispatched on "main" + # If we are changing the way in which we manage module renaming then it + # MUST go through PR review to main; only then can it open PRs. + if: github.event_name == 'workflow_dispatch' && github.ref != 'refs/heads/main' + uses: devops-infra/action-pull-request@v0.5.5 + with: + github_token: ${{ secrets.GITHUB_TOKEN }} + source_branch: ${{ env.output_branch }} + target_branch: renamed-go-module + title: "[AUTO] Rename upstream Go module at `${{ env.source_commit }}`" + body: "_PR generated by GitHub Action_" From 21122c043a78678934e3b4fcb4da09b113daa8fc Mon Sep 17 00:00:00 2001 From: Arran Schlosberg <519948+ARR4N@users.noreply.github.com> Date: Fri, 11 Oct 2024 22:35:31 +0100 Subject: [PATCH 034/142] fix: run renaming workflow if branch `== main` (#58) ## Why this should be merged #51 had a bug when checking whether or not to open a PR.

The workflow no longer opens a PR to the `renamed-go-module` branch as it's redundant and the generated branch can be used directly. The commit message includes the `workflow_dispatch` trigger branch as well as a hash of the workflow file for a complete audit trail. I removed the commented-out PR trigger as it's unnecessary. In development we can now just trigger the workflow on the dev branch. ## How this was tested Inspecting [the commit](https://github.com/ava-labs/libevm/commit/572b8ab74eeb2afab3dbf353207d80145c2a1742) generated by a [workflow run](https://github.com/ava-labs/libevm/actions/runs/11357025696/job/31589219847).

In doing so, it [maintains an invariant](https://github.com/ava-labs/libevm/blob/cb7eb89341132f301680848d8faea6a5568dc326/eth/tracers/native/prestate.go#L160) that is expected when `CaptureState(vm.SLOAD, ...)` is called—breaking the invariant results in a panic due to a nil map. The fix involves (a) maintaining the invariant as part of `CaptureEnter()` (previously a no-op); and (b) calling said method inside `vm.PrecompileEnvironment.Call()`. The latter has the added benefit of properly handling all tracing involving an outbound call from precompiles. ## How this was tested New integration test demonstrates that the tracer can log the retrieved storage value. --------- Co-authored-by: Darioush Jalali --- core/vm/contracts.libevm.go | 39 +++++++++++-------- core/vm/contracts.libevm_test.go | 54 +++++++++++++++++++++++++-- core/vm/environment.libevm.go | 21 +++++++++-- eth/tracers/native/prestate_libevm.go | 37 ++++++++++++++++++ 4 files changed, 128 insertions(+), 23 deletions(-) create mode 100644 eth/tracers/native/prestate_libevm.go diff --git a/core/vm/contracts.libevm.go b/core/vm/contracts.libevm.go index a6c9c1a860e..c235d0a7809 100644 --- a/core/vm/contracts.libevm.go +++ b/core/vm/contracts.libevm.go @@ -54,31 +54,40 @@ type evmCallArgs struct { } // A CallType refers to a *CALL* [OpCode] / respective method on [EVM]. -type CallType uint8 +type CallType OpCode const ( - UnknownCallType CallType = iota - Call - CallCode - DelegateCall - StaticCall + Call = CallType(CALL) + CallCode = CallType(CALLCODE) + DelegateCall = CallType(DELEGATECALL) + StaticCall = CallType(STATICCALL) ) +func (t CallType) isValid() bool { + switch t { + case Call, CallCode, DelegateCall, StaticCall: + return true + default: + return false + } +} + // String returns a human-readable representation of the CallType. func (t CallType) String() string { - switch t { - case Call: - return "Call" - case CallCode: - return "CallCode" - case DelegateCall: - return "DelegateCall" - case StaticCall: - return "StaticCall" + if t.isValid() { + return t.OpCode().String() } return fmt.Sprintf("Unknown %T(%d)", t, t) } +// OpCode returns t's equivalent OpCode. +func (t CallType) OpCode() OpCode { + if t.isValid() { + return OpCode(t) + } + return INVALID +} + // run runs the [PrecompiledContract], differentiating between stateful and // regular types. func (args *evmCallArgs) run(p PrecompiledContract, input []byte, suppliedGas uint64) (ret []byte, remainingGas uint64, err error) { diff --git a/core/vm/contracts.libevm_test.go b/core/vm/contracts.libevm_test.go index 59c07bbf9a7..8c451ff66c8 100644 --- a/core/vm/contracts.libevm_test.go +++ b/core/vm/contracts.libevm_test.go @@ -17,6 +17,7 @@ package vm_test import ( "bytes" + "encoding/json" "fmt" "math/big" "reflect" @@ -33,6 +34,8 @@ import ( "github.com/ava-labs/libevm/core/types" "github.com/ava-labs/libevm/core/vm" "github.com/ava-labs/libevm/crypto" + "github.com/ava-labs/libevm/eth/tracers" + _ "github.com/ava-labs/libevm/eth/tracers/native" "github.com/ava-labs/libevm/libevm" "github.com/ava-labs/libevm/libevm/ethtest" "github.com/ava-labs/libevm/libevm/hookstest" @@ -338,7 +341,7 @@ func TestInheritReadOnly(t *testing.T) { rng := ethtest.NewPseudoRand(42) contractAddr := rng.Address() state.CreateAccount(contractAddr) - state.SetCode(contractAddr, convertBytes[vm.OpCode, byte](contract)) + state.SetCode(contractAddr, convertBytes[vm.OpCode, byte](contract...)) // (3) @@ -404,7 +407,7 @@ func makeReturnProxy(t *testing.T, dest common.Address, call vm.OpCode) []vm.OpC } contract = append(contract, vm.PUSH20) - contract = append(contract, convertBytes[byte, vm.OpCode](dest[:])...) + contract = append(contract, convertBytes[byte, vm.OpCode](dest[:]...)...) contract = append(contract, p0, // gas @@ -417,7 +420,7 @@ func makeReturnProxy(t *testing.T, dest common.Address, call vm.OpCode) []vm.OpC return contract } -func convertBytes[From ~byte, To ~byte](buf []From) []To { +func convertBytes[From ~byte, To ~byte](buf ...From) []To { out := make([]To, len(buf)) for i, b := range buf { out[i] = To(b) @@ -672,7 +675,7 @@ func TestPrecompileMakeCall(t *testing.T) { evm.Origin = eoa state.CreateAccount(caller) proxy := makeReturnProxy(t, sut, tt.incomingCallType) - state.SetCode(caller, convertBytes[vm.OpCode, byte](proxy)) + state.SetCode(caller, convertBytes[vm.OpCode, byte](proxy...)) got, _, err := evm.Call(vm.AccountRef(eoa), caller, tt.eoaTxCallData, 1e6, uint256.NewInt(0)) require.NoError(t, err) @@ -681,6 +684,49 @@ func TestPrecompileMakeCall(t *testing.T) { } } +func TestPrecompileCallWithTracer(t *testing.T) { + // The native pre-state tracer, when logging storage, assumes an invariant + // that is broken by a precompile calling another contract.

Other interfaces are introduced to avoid having to modify `{hash,path}db.Database.Reader()` return values. The explicit `DBOverride` field means that we don't have to modify any of the `triedb` constructor beyond adding a single line immediately before the return. This leaves all modifications of original files entirely mechanistic. This is, however, at the expense of compile-time guarantees of the overriding database being either a `HashBackend` or a `PathBackend`. ## How this was tested Unit test demonstrating override + plumbing. --------- Co-authored-by: Darioush Jalali --- triedb/database.go | 25 +++++---- triedb/database.libevm.go | 97 ++++++++++++++++++++++++++++++++++ triedb/database.libevm_test.go | 54 +++++++++++++++++++ 3 files changed, 167 insertions(+), 9 deletions(-) create mode 100644 triedb/database.libevm.go create mode 100644 triedb/database.libevm_test.go diff --git a/triedb/database.go b/triedb/database.go index 4ce4de54a5d..6ec8b157a74 100644 --- a/triedb/database.go +++ b/triedb/database.go @@ -36,6 +36,8 @@ type Config struct { IsVerkle bool // Flag whether the db is holding a verkle tree HashDB *hashdb.Config // Configs for hash-based scheme PathDB *pathdb.Config // Configs for experimental path-based scheme + + DBOverride DBConstructor // Injects an arbitrary backend-database implementation } // HashDefaults represents a config for using hash-based scheme with @@ -104,6 +106,9 @@ func NewDatabase(diskdb ethdb.Database, config *Config) *Database { diskdb: diskdb, preimages: preimages, } + if db.overrideBackend(diskdb, config) { + return db + } if config.HashDB != nil && config.PathDB != nil { log.Crit("Both 'hash' and 'path' mode are configured") } @@ -126,6 +131,8 @@ func NewDatabase(diskdb ethdb.Database, config *Config) *Database { // An error will be returned if the requested state is not available. func (db *Database) Reader(blockRoot common.Hash) (database.Reader, error) { switch b := db.backend.(type) { + case ReaderProvider: + return b.Reader(blockRoot) case *hashdb.Database: return b.Reader(blockRoot) case *pathdb.Database: @@ -221,7 +228,7 @@ func (db *Database) InsertPreimage(preimages map[common.Hash][]byte) { // // It's only supported by hash-based database and will return an error for others. func (db *Database) Cap(limit common.StorageSize) error { - hdb, ok := db.backend.(*hashdb.Database) + hdb, ok := db.backend.(HashDB) if !ok { return errors.New("not supported") } @@ -237,7 +244,7 @@ func (db *Database) Cap(limit common.StorageSize) error { // // It's only supported by hash-based database and will return an error for others. func (db *Database) Reference(root common.Hash, parent common.Hash) error { - hdb, ok := db.backend.(*hashdb.Database) + hdb, ok := db.backend.(HashDB) if !ok { return errors.New("not supported") } @@ -248,7 +255,7 @@ func (db *Database) Reference(root common.Hash, parent common.Hash) error { // Dereference removes an existing reference from a root node.

This is intended as a temporary solution while we investigate having the state root affected by the block hash to remove path ambiguity. ## How this works Introduction of: 1. `state.SnapshotTree` interface to match methods required on `snapshot.Tree` as used by `state.StateDB`; and 2. `stateconf` package for variadic options plumbed by `StateDB.Commit()` through to `SnapshotTree.Update()`. Although variadic (to maintain function call-signature compatibility) only the `stateconf.WithUpdatePayload(any)` is expected to be used. Recipients of the options can access the payload with `stateconf.ExtractUpdatePayload()`. ## How this was tested Unit test demonstrating propagation of `stateconf.UpdateOption` payload. --- core/state/snapshot/snapshot.go | 5 +- core/state/statedb.go | 10 ++-- core/state/statedb.libevm.go | 54 +++++++++++++++++++++ core/state/statedb.libevm_test.go | 80 +++++++++++++++++++++++++++++++ libevm/stateconf/conf.go | 45 +++++++++++++++++ 5 files changed, 189 insertions(+), 5 deletions(-) create mode 100644 core/state/statedb.libevm.go create mode 100644 core/state/statedb.libevm_test.go create mode 100644 libevm/stateconf/conf.go diff --git a/core/state/snapshot/snapshot.go b/core/state/snapshot/snapshot.go index b65bdf96039..e000c563e41 100644 --- a/core/state/snapshot/snapshot.go +++ b/core/state/snapshot/snapshot.go @@ -27,6 +27,7 @@ import ( "github.com/ava-labs/libevm/core/rawdb" "github.com/ava-labs/libevm/core/types" "github.com/ava-labs/libevm/ethdb" + "github.com/ava-labs/libevm/libevm/stateconf" "github.com/ava-labs/libevm/log" "github.com/ava-labs/libevm/metrics" "github.com/ava-labs/libevm/rlp" @@ -348,7 +349,9 @@ func (t *Tree) Snapshots(root common.Hash, limits int, nodisk bool) []Snapshot { // Update adds a new snapshot into the tree, if that can be linked to an existing // old parent.

We therefore have to use a `release` suffix (`"release" > "rc"` in ASCII). This all became too much to expect to be done manually so I chucked it in code instead. ## How this was tested Unit test demonstrates expectation of version ordering. --- go.mod | 2 + params/version.libevm.go | 93 +++++++++++++++++++++++++++++++++++ params/version.libevm_test.go | 86 ++++++++++++++++++++++++++++++++ 3 files changed, 181 insertions(+) create mode 100644 params/version.libevm.go create mode 100644 params/version.libevm_test.go diff --git a/go.mod b/go.mod index 91ce2782224..4c3ccc4d5ce 100644 --- a/go.mod +++ b/go.mod @@ -2,6 +2,8 @@ module github.com/ava-labs/libevm go 1.20 +retract v1.13.14-0.1.0-rc.1 // bad semver format ("0-rc" grouping) considered > .rc-2 + require ( github.com/Azure/azure-sdk-for-go/sdk/storage/azblob v1.2.0 github.com/Microsoft/go-winio v0.6.1 diff --git a/params/version.libevm.go b/params/version.libevm.go new file mode 100644 index 00000000000..463e6f7420d --- /dev/null +++ b/params/version.libevm.go @@ -0,0 +1,93 @@ +// Copyright 2024 the libevm authors. +// +// The libevm additions to go-ethereum are free software: you can redistribute +// them and/or modify them under the terms of the GNU Lesser General Public License +// as published by the Free Software Foundation, either version 3 of the License, +// or (at your option) any later version. +// +// The libevm additions are distributed in the hope that they will be useful, +// but WITHOUT ANY WARRANTY; without even the implied warranty of +// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

(e.g. `types.Header`). ## How this works Introduces `pseudo.Accessor` to abstract the reusable code. ## How this was tested Existing unit tests. Note that the `types.StateAccount` tests needed a minor refactor to provide the assertions with access to the `ExtraPayloads[T]` without introducing generic types anywhere. --- core/state/state.libevm.go | 8 +- core/state/state.libevm_test.go | 2 +- core/state/state_object.libevm_test.go | 4 +- core/types/rlp_payload.libevm.go | 30 ++------ .../state_account_storage.libevm_test.go | 76 +++++++++---------- libevm/pseudo/accessor.go | 49 ++++++++++++ params/config.libevm.go | 63 +++++---------- params/config.libevm_test.go | 28 +++---- params/example.libevm_test.go | 4 +- params/hooks.libevm_test.go | 6 +- 10 files changed, 135 insertions(+), 135 deletions(-) create mode 100644 libevm/pseudo/accessor.go diff --git a/core/state/state.libevm.go b/core/state/state.libevm.go index 40c5b39b1ee..9cdcf047eab 100644 --- a/core/state/state.libevm.go +++ b/core/state/state.libevm.go @@ -27,7 +27,7 @@ import ( func GetExtra[SA any](s *StateDB, p types.ExtraPayloads[SA], addr common.Address) SA { stateObject := s.getStateObject(addr) if stateObject != nil { - return p.FromPayloadCarrier(&stateObject.data) + return p.StateAccount.Get(&stateObject.data) } var zero SA return zero @@ -45,9 +45,9 @@ func setExtraOnObject[SA any](s *stateObject, p types.ExtraPayloads[SA], addr co s.db.journal.append(extraChange[SA]{ payloads: p, account: &addr, - prev: p.FromPayloadCarrier(&s.data), + prev: p.StateAccount.Get(&s.data), }) - p.SetOnPayloadCarrier(&s.data, extra) + p.StateAccount.Set(&s.data, extra) } // extraChange is a [journalEntry] for [SetExtra] / [setExtraOnObject]. @@ -60,5 +60,5 @@ type extraChange[SA any] struct { func (e extraChange[SA]) dirtied() *common.Address { return e.account } func (e extraChange[SA]) revert(s *StateDB) { - e.payloads.SetOnPayloadCarrier(&s.getStateObject(*e.account).data, e.prev) + e.payloads.StateAccount.Set(&s.getStateObject(*e.account).data, e.prev) } diff --git a/core/state/state.libevm_test.go b/core/state/state.libevm_test.go index d108779c291..7d7ab190808 100644 --- a/core/state/state.libevm_test.go +++ b/core/state/state.libevm_test.go @@ -87,7 +87,7 @@ func TestGetSetExtra(t *testing.T) { Root: types.EmptyRootHash, CodeHash: types.EmptyCodeHash[:], } - payloads.SetOnPayloadCarrier(want, extra) + payloads.StateAccount.Set(want, extra) if diff := cmp.Diff(want, got); diff != "" { t.Errorf("types.FullAccount(%T.Account()) diff (-want +got):\n%s", iter, diff) diff --git a/core/state/state_object.libevm_test.go b/core/state/state_object.libevm_test.go index a6bfc5e9954..cba90bf80c4 100644 --- a/core/state/state_object.libevm_test.go +++ b/core/state/state_object.libevm_test.go @@ -46,7 +46,7 @@ func TestStateObjectEmpty(t *testing.T) { { name: "explicit false bool", registerAndSet: func(acc *types.StateAccount) { - types.RegisterExtras[bool]().SetOnPayloadCarrier(acc, false) + types.RegisterExtras[bool]().StateAccount.Set(acc, false) }, wantEmpty: true, }, @@ -60,7 +60,7 @@ func TestStateObjectEmpty(t *testing.T) { { name: "true bool", registerAndSet: func(acc *types.StateAccount) { - types.RegisterExtras[bool]().SetOnPayloadCarrier(acc, true) + types.RegisterExtras[bool]().StateAccount.Set(acc, true) }, wantEmpty: false, }, diff --git a/core/types/rlp_payload.libevm.go b/core/types/rlp_payload.libevm.go index f6d13adfa52..12dbab3e08f 100644 --- a/core/types/rlp_payload.libevm.go +++ b/core/types/rlp_payload.libevm.go @@ -38,7 +38,12 @@ import ( // The payload can be accessed via the [ExtraPayloads.FromPayloadCarrier] method // of the accessor returned by RegisterExtras. func RegisterExtras[SA any]() ExtraPayloads[SA] { - var extra ExtraPayloads[SA] + extra := ExtraPayloads[SA]{ + StateAccount: pseudo.NewAccessor[ExtraPayloadCarrier, SA]( + func(a ExtraPayloadCarrier) *pseudo.Type { return a.extra().payload() }, + func(a ExtraPayloadCarrier, t *pseudo.Type) { a.extra().t = t }, + ), + } registeredExtras.MustRegister(&extraConstructors{ stateAccountType: func() string { var x SA @@ -81,7 +86,7 @@ func (e *StateAccountExtra) clone() *StateAccountExtra { // [StateAccount] and [SlimAccount] structs.

As there is already a `Header.EncodeRLP()` method we either have to modify the generated code or rename the generated method—this PR does the latter. ## How this works The `rlpgen -internal_methods` flag changes the generated methods from `EncodeRLP()` and `DecodeRLP()` to `encodeRLP()` and `decodeRLP()`, respectively. A new CI job checks that generated code is up to date. We can then implement our own `Header.EncodeRLP()` that either overrides or falls back on the original. It appears that `core/gen_genesis.go` was out of date but only because of formatting. ## How this was tested I deliberately excluded the change to `core/types/gen_header_rlp.go` to confirm that the new workflow [detects](https://github.com/ava-labs/libevm/actions/runs/12259667481/job/34202386378?pr=86#step:5:92) the change and fails. The actual change can be inspected via the code diff. --- .github/workflows/go.yml | 17 +++++++++++ core/gen_genesis.go | 56 ++++++++++++++++++------------------ core/types/block.go | 2 +- core/types/block.libevm.go | 29 +++++++++++++++++++ core/types/gen_header_rlp.go | 2 +- rlp/rlpgen/gen.go | 9 ++++-- rlp/rlpgen/gen.libevm.go | 31 ++++++++++++++++++++ rlp/rlpgen/main.go | 5 ++++ 8 files changed, 119 insertions(+), 32 deletions(-) create mode 100644 core/types/block.libevm.go create mode 100644 rlp/rlpgen/gen.libevm.go diff --git a/.github/workflows/go.yml b/.github/workflows/go.yml index ebdecbf3c70..db48851ef50 100644 --- a/.github/workflows/go.yml +++ b/.github/workflows/go.yml @@ -24,3 +24,20 @@ jobs: - name: Run non-flaky tests concurrently run: | go test -short $(go list ./... | grep -Pv "${FLAKY_REGEX}");

This PR adds support for arbitrary RLP encoding coupled with type-safe extra payloads. ## How this works Equivalent to #1 (`params`) and #44 (`types.StateAccount`) registration of pseudo-generic payloads. The only major difference is the guarantee of a non-nil payload pointer, which means that the payload hooks are never called on nil pointers as this would make it difficult to decode RLP into them. ## How this was tested Round-trip RLP {en,de}coding via a registered stub hook. --------- Signed-off-by: Arran Schlosberg <519948+ARR4N@users.noreply.github.com> Co-authored-by: Quentin McGaw --- core/state/state.libevm.go | 25 ++-- core/state/state.libevm_test.go | 4 +- core/state/state_object.libevm_test.go | 6 +- core/types/block.go | 3 + core/types/block.libevm.go | 63 +++++++++- core/types/block.libevm_test.go | 113 ++++++++++++++++++ .../types/rlp_backwards_compat.libevm_test.go | 45 ++++++- core/types/rlp_payload.libevm.go | 75 ++++++++---- core/types/state_account.libevm_test.go | 4 +- .../state_account_storage.libevm_test.go | 8 +- params/config.libevm.go | 3 +- 11 files changed, 294 insertions(+), 55 deletions(-) create mode 100644 core/types/block.libevm_test.go diff --git a/core/state/state.libevm.go b/core/state/state.libevm.go index 9cdcf047eab..369fea975b9 100644 --- a/core/state/state.libevm.go +++ b/core/state/state.libevm.go @@ -19,40 +19,41 @@ package state import ( "github.com/ava-labs/libevm/common" "github.com/ava-labs/libevm/core/types" + "github.com/ava-labs/libevm/libevm/pseudo" ) // GetExtra returns the extra payload from the [types.StateAccount] associated -// with the address, or a zero-value `SA` if not found.

The most notable simplification occurs when there are multiple error paths that return early and have to account for consumed gas (any local solution would likely just mirror this one). This forms part of a broader, long-term direction of feature parity between precompiled and bytecode contracts, exposed via `vm.PrecompileEnvironment`. The `vm.Contract.Value()` method is also exposed as a natural accompaniment to this change. ## How this works The original signature for `vm.PrecompiledStatefulContract` received the amount of gas available and then returned the amount remaining; this has been removed in lieu of exposing the existing `vm.Contract.UseGas()` method via the `vm.PrecompileEnvironment`. A new `legacy` package wraps the old signature and converts it to a new one so `ava-labs/coreth` doesn't need to be refactored. ```go func oldPrecompile(env vm.PrecompileEnvironment, input []byte, gas uint64) ([]byte, uint64, error) { // ... if err != nil { return nil, gas - gasCost, err // pattern susceptible to bugs; should it be `nil, gas, err` ? } // ... return output, gas - gasCost, nil } func newPrecompile(env vm.PrecompileEnvironment, input []byte) ([]byte, error) { // The original `gas` argument is still available as `env.Gas()` // ... if !env.UseGas(gasCost) { // an explicit point at which gas is consumed return nil, vm.ErrOutOfGas } // ... if err != nil { return nil, err } // ... return output, nil } ``` ## How this was tested Existing unit test modified to use the `legacy` adaptor. --------- Signed-off-by: Arran Schlosberg <519948+ARR4N@users.noreply.github.com> Co-authored-by: Quentin McGaw --- core/vm/contracts.go | 4 +- core/vm/contracts.libevm.go | 47 +++++++++++++--------- core/vm/contracts.libevm_test.go | 67 +++++++++++++++++++------------- core/vm/environment.libevm.go | 34 +++++++++++++--- core/vm/libevm_test.go | 2 +- libevm/legacy/legacy.go | 39 +++++++++++++++++++ 6 files changed, 141 insertions(+), 52 deletions(-) create mode 100644 libevm/legacy/legacy.go diff --git a/core/vm/contracts.go b/core/vm/contracts.go index dc07de85025..a869debebba 100644 --- a/core/vm/contracts.go +++ b/core/vm/contracts.go @@ -177,7 +177,9 @@ func (args *evmCallArgs) RunPrecompiledContract(p PrecompiledContract, input []b return nil, 0, ErrOutOfGas } suppliedGas -= gasCost - return args.run(p, input, suppliedGas) + args.gasRemaining = suppliedGas + output, err := args.run(p, input) + return output, args.gasRemaining, err } // ECRECOVER implemented as a native contract. diff --git a/core/vm/contracts.libevm.go b/core/vm/contracts.libevm.go index c235d0a7809..66e3c91783a 100644 --- a/core/vm/contracts.libevm.go +++ b/core/vm/contracts.libevm.go @@ -45,11 +45,11 @@ type evmCallArgs struct { callType CallType // args:start - caller ContractRef - addr common.Address - input []byte - gas uint64 - value *uint256.Int + caller ContractRef + addr common.Address + input []byte + gasRemaining uint64 + value *uint256.Int // args:end } @@ -89,20 +89,26 @@ func (t CallType) OpCode() OpCode { } // run runs the [PrecompiledContract], differentiating between stateful and -// regular types. -func (args *evmCallArgs) run(p PrecompiledContract, input []byte, suppliedGas uint64) (ret []byte, remainingGas uint64, err error) { - if p, ok := p.(statefulPrecompile); ok { - return p(args.env(), input, suppliedGas) +// regular types, updating `args.gasRemaining` in the stateful case. +func (args *evmCallArgs) run(p PrecompiledContract, input []byte) (ret []byte, err error) { + switch p := p.(type) { + default: + return p.Run(input) + case statefulPrecompile: + env := args.env() + ret, err := p(env, input) + args.gasRemaining = env.Gas() + return ret, err } - // Gas consumption for regular precompiles was already handled by the native - // RunPrecompiledContract(), which called this method. - ret, err = p.Run(input) - return ret, suppliedGas, err } // PrecompiledStatefulContract is the stateful equivalent of a // [PrecompiledContract]. -type PrecompiledStatefulContract func(env PrecompileEnvironment, input []byte, suppliedGas uint64) (ret []byte, remainingGas uint64, err error) +// +// Instead of receiving and returning gas arguments, stateful precompiles use +// the respective methods on [PrecompileEnvironment].

This is then used for all hooks, new (JSON) and old (RLP). ## How this was tested Extension of existing unit tests. --- core/types/block.go | 1 + core/types/block.libevm.go | 60 ++++++++++++------- core/types/block.libevm_test.go | 102 ++++++++++++++++++++++++++------ core/types/gen_header_json.go | 4 +- 4 files changed, 126 insertions(+), 41 deletions(-) diff --git a/core/types/block.go b/core/types/block.go index 9cf53db28a4..692cf01c076 100644 --- a/core/types/block.go +++ b/core/types/block.go @@ -60,6 +60,7 @@ func (n *BlockNonce) UnmarshalText(input []byte) error { } //go:generate go run github.com/fjl/gencodec -type Header -field-override headerMarshaling -out gen_header_json.go +//go:generate go run ../../libevm/cmd/internalise -file gen_header_json.go Header.MarshalJSON Header.UnmarshalJSON //go:generate go run ../../rlp/rlpgen -type Header -out gen_header_rlp.go //go:generate go run ../../libevm/cmd/internalise -file gen_header_rlp.go Header.EncodeRLP diff --git a/core/types/block.libevm.go b/core/types/block.libevm.go index 1a4dca03818..ca1e6d7e57d 100644 --- a/core/types/block.libevm.go +++ b/core/types/block.libevm.go @@ -17,6 +17,7 @@ package types import ( + "encoding/json" "fmt" "io" @@ -27,40 +28,50 @@ import ( // HeaderHooks are required for all types registered with [RegisterExtras] for // [Header] payloads. type HeaderHooks interface { + MarshalJSON(*Header) ([]byte, error) //nolint:govet // Type-specific override hook + UnmarshalJSON(*Header, []byte) error //nolint:govet EncodeRLP(*Header, io.Writer) error DecodeRLP(*Header, *rlp.Stream) error } +// hooks returns the Header's registered HeaderHooks, if any, otherwise a +// [NOOPHeaderHooks] suitable for running default behaviour. +func (h *Header) hooks() HeaderHooks { + if r := registeredExtras;

The `AppendRLPFields(rlp.EncoderBuffer, ...)` hook exploits this and plugs in before all `rlp:"optional"`-tagged fields to allow for inclusion of any new fields. The `EncoderBuffer` SHOULD be used as the `io.Writer` passed when encoding each field: `rlp.Encode(buffer, fieldValue)`. `Body` doesn't have `{En,De}codeRLP` methods so they are implemented to identically replicate original behaviour when a no-op hook is present. This pattern is sufficient for the `ava-labs/coreth` modifications of `Body` but can be modified / extended for more complex scenarios, like `Header`. > [!NOTE] > This PR does not include registration of the hooks as that was not the initial goal and adding them would create too much PR bloat. There is a placeholder `var todoRegisteredBodyHooks` global variable that can only be set in tests. ## How this was tested - Backwards compatibility: the new methods are fuzzed against a `type withoutMethods Body` passed directly to `rlp.{En,De}code()` - `coreth` compatibility: unit test of a local implementation of `BodyHooks` demonstrating reproducibility of RLP encoding. --------- Signed-off-by: Arran Schlosberg <519948+ARR4N@users.noreply.github.com> Co-authored-by: Quentin McGaw --- common/pointer.libevm.go | 20 ++ core/types/block.libevm.go | 104 ++++++++- .../types/rlp_backwards_compat.libevm_test.go | 198 +++++++++++++++++- libevm/cmpeth/cmpeth.go | 66 ++++++ rlp/list.libevm.go | 77 +++++++ rlp/list.libevm_test.go | 56 +++++ 6 files changed, 518 insertions(+), 3 deletions(-) create mode 100644 common/pointer.libevm.go create mode 100644 libevm/cmpeth/cmpeth.go create mode 100644 rlp/list.libevm.go create mode 100644 rlp/list.libevm_test.go diff --git a/common/pointer.libevm.go b/common/pointer.libevm.go new file mode 100644 index 00000000000..c51b930ee31 --- /dev/null +++ b/common/pointer.libevm.go @@ -0,0 +1,20 @@ +// Copyright 2025 the libevm authors. +// +// The libevm additions to go-ethereum are free software: you can redistribute +// them and/or modify them under the terms of the GNU Lesser General Public License +// as published by the Free Software Foundation, either version 3 of the License, +// or (at your option) any later version. +// +// The libevm additions are distributed in the hope that they will be useful, +// but WITHOUT ANY WARRANTY; without even the implied warranty of +// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Resulted in [failed smoke tests](https://github.com/ava-labs/libevm/actions/runs/13198798601) due to ABI-binding templates not being updated. ## How this works Only (1) is necessary for the fix but the others were added for convenience as relevant to this PR: 1. Replace module name in `*.go.tpl` files; 2. As above for `*.proto` files (`go_package` option); 3. Remove concurrency limitations as they're unnecessary with a manually triggered workflow; and 4. Display all tags that point to the source commit as they're useful for inspection of version. ## How this was tested [Successful workflow run](https://github.com/ava-labs/libevm/actions/runs/13199663099/job/36848609786) at upstream v1.15.0. For the modifications, respectively: 1. Smoke tests pass and no `.go.tpl` files in [Remnant references](https://github.com/ava-labs/libevm/actions/runs/13199663099/job/36848609786#step:9:1); 2. As above re remnant references; 3. N/A; and 4.

The RLP override hook now only needs to return the fields of interest, which MAY come from either the `Body` or the registered extra. This pattern allows for arbitrary modification of upstream fields via (1) reordering; (2) addition; (3) deletion; and (4) inverting required vs optional status. While less important for `Body`, this allows for complete support of `ava-labs/coreth` `Header` modifications, which make use of 1-3. ## How this was tested Existing backwards-compatibility tests + new unit tests for introduced functionality. --------- Signed-off-by: Arran Schlosberg <519948+ARR4N@users.noreply.github.com> Co-authored-by: Quentin McGaw --- core/types/block.libevm.go | 92 +++----- .../types/rlp_backwards_compat.libevm_test.go | 54 ++--- rlp/fields.libevm.go | 139 +++++++++++ rlp/fields.libevm_test.go | 218 ++++++++++++++++++ 4 files changed, 412 insertions(+), 91 deletions(-) create mode 100644 rlp/fields.libevm.go create mode 100644 rlp/fields.libevm_test.go diff --git a/core/types/block.libevm.go b/core/types/block.libevm.go index 094613ee1e3..832fe421f0a 100644 --- a/core/types/block.libevm.go +++ b/core/types/block.libevm.go @@ -112,79 +112,26 @@ func (*NOOPHeaderHooks) DecodeRLP(h *Header, s *rlp.Stream) error { } func (*NOOPHeaderHooks) PostCopy(dst *Header) {} -var ( - _ interface { - rlp.Encoder - rlp.Decoder - } = (*Body)(nil) - - // The implementations of [Body.EncodeRLP] and [Body.DecodeRLP] make - // assumptions about the struct fields and their order, which we lock in here as a change - // detector.

This type is modified to implement the `rlp.Encoder` and `Decoder` methods as a point to inject hooks using `rlp.Fields` (as in #120 for `Body`). `Block` shares the same registered extra type as `Body`. Unlike `Header`, which has its own field in a `Block`, the fields in `Body` are promoted to be carried directly. This suggests that (at least for pure data payloads) the modifications might be equivalent (and `ava-labs/coreth` evidences this). Should different payloads be absolutely required in the future, we can split the types—the `RegisterExtras` signature is already too verbose though 😢. ## How this was tested Explicit inclusion of a backwards-compatibility test for `NOOPBlockBodyHooks` + implicit testing via the multiple upstream tests in `block_test.go`. Re implicit testing: default behaviour is now to use the noop hooks even when no registration is performed, but if we change this then the tests in `block_test.go` can still be called as subtests from a test that explicitly registers noops. --------- Signed-off-by: Arran Schlosberg <519948+ARR4N@users.noreply.github.com> Co-authored-by: Quentin McGaw --- core/state/state.libevm_test.go | 2 +- core/state/state_object.libevm_test.go | 6 +- core/types/backwards_compat.libevm_test.go | 122 ++++++++++++++++-- .../backwards_compat_diffpkg.libevm_test.go | 2 +- core/types/block.go | 11 +- core/types/block.libevm.go | 86 +++++++++--- core/types/block.libevm_test.go | 72 ++++++++++- core/types/rlp_payload.libevm.go | 106 ++++++++++++--- core/types/state_account.libevm_test.go | 4 +- .../state_account_storage.libevm_test.go | 8 +- 10 files changed, 354 insertions(+), 65 deletions(-) diff --git a/core/state/state.libevm_test.go b/core/state/state.libevm_test.go index bd909203102..0d816038f0c 100644 --- a/core/state/state.libevm_test.go +++ b/core/state/state.libevm_test.go @@ -47,7 +47,7 @@ func TestGetSetExtra(t *testing.T) { // test deep copying. payloads := types.RegisterExtras[ types.NOOPHeaderHooks, *types.NOOPHeaderHooks, -

Introduces `log.Lazy` functions to allow expensive logging operations to be computed i.f.f. required by the logging level. 2. Adds `Info` logging for registration of types and `Debug` logging for all else. 3. Only paths that change behaviour in a potentially unpredictable manner are logged; of note, RLP / JSON encoding is _not_ considered unpredictable given that registered extras are logged. 4. The minimal viable package, `set`, was necessary because we don't want to depend on `avalanchego` and the `hashicorp/go-set` latest version requires a later version of Go. #153 tracks a swap to the latter when possible. The `eth/tracers/internal/tracetest` test flaked at least twice (unrelated to these changes) so I've marked it as such since it's not worth a separate PR. ## How this was tested New unit test on `log.Lazy` + `set` methods. Existing CI for the rest as it's a refactor. --- .github/workflows/go.yml | 2 +- core/state_transition.libevm.go | 16 +++++++- core/types/rlp_payload.libevm.go | 7 ++++ core/vm/contracts.go | 5 +-- core/vm/contracts.libevm.go | 29 ++++++++++++++ core/vm/evm.go | 6 +-- core/vm/evm.libevm.go | 45 +++++++++++++++++++++ libevm/set/set.go | 59 ++++++++++++++++++++++++++++ libevm/set/set_test.go | 56 ++++++++++++++++++++++++++ log/value.libevm.go | 41 +++++++++++++++++++ log/value.libevm_test.go | 67 ++++++++++++++++++++++++++++++++ params/config.libevm.go | 7 ++++ 12 files changed, 331 insertions(+), 9 deletions(-) create mode 100644 core/vm/evm.libevm.go create mode 100644 libevm/set/set.go create mode 100644 libevm/set/set_test.go create mode 100644 log/value.libevm.go create mode 100644 log/value.libevm_test.go diff --git a/.github/workflows/go.yml b/.github/workflows/go.yml index 701fe6b4cd2..47e20c549fd 100644 --- a/.github/workflows/go.yml +++ b/.github/workflows/go.yml @@ -22,7 +22,7 @@ jobs: go_test_short: env: - FLAKY_REGEX: "ava-labs/libevm/(triedb/pathdb|eth|eth/tracers/js|eth/tracers/logger|accounts/abi/bind|accounts/keystore|eth/downloader|miner|ethclient|ethclient/gethclient|eth/catalyst)$" + FLAKY_REGEX: "ava-labs/libevm/(triedb/pathdb|eth|eth/tracers/js|eth/tracers/logger|eth/tracers/internal/tracetest|accounts/abi/bind|accounts/keystore|eth/downloader|miner|ethclient|ethclient/gethclient|eth/catalyst)$" runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 diff --git a/core/state_transition.libevm.go b/core/state_transition.libevm.go index 49e509d5637..701cc4d5ee7 100644 --- a/core/state_transition.libevm.go +++ b/core/state_transition.libevm.go @@ -16,10 +16,24 @@ package core +import ( + "github.com/ava-labs/libevm/log" +) + // canExecuteTransaction is a convenience wrapper for calling the // [params.RulesHooks.CanExecuteTransaction] hook. func (st *StateTransition) canExecuteTransaction() error { bCtx := st.evm.Context rules := st.evm.ChainConfig().Rules(bCtx.BlockNumber, bCtx.Random != nil, bCtx.Time) - return rules.Hooks().CanExecuteTransaction(st.msg.From, st.msg.To, st.state) + if err := rules.Hooks().CanExecuteTransaction(st.msg.From, st.msg.To, st.state);

We'll be building with 1.23 via `avalanchego` anyway (which doesn't transitively import `memsize`) so we want to run tests with the correct version. It will also unblock #154. ## How this works ✂️ We already cherry-pick the upstream commit (e4675771eda550e7eeb63a8884816982c1980644) that removes `memsize` when on release branches so we instead do it ourselves and no longer cherry-pick. To avoid conflicts at the next `geth` sync, this PR should be reverted before performing the merge.

094/142] feat(rlp/rlpgen): support alias types (#154) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Why this should be merged To be able to generate RLP code using type aliases (defined e.g. in `coreth`). This can and should be PR-ed upstream as well I think. ## How this works Call `types.Unalias()` at the start of `buildContext.makeOp()`. The alternative of adding a `case` to the switch statement adds unnecessary recursive calls while `types.Unalias()` is a no-op if not an alias. ## How this was tested New `rlpgen` unit test with aliases of well-known types that have special handling—these make their proper handling easy to spot when inspecting generated code. A recursive alias in the same test also demonstrates full alias resolution. --------- Co-authored-by: Arran Schlosberg --- rlp/rlpgen/gen.go | 2 +- rlp/rlpgen/gen_test.go | 2 +- rlp/rlpgen/testdata/alias.in.txt | 22 ++++++++++++++++ rlp/rlpgen/testdata/alias.out.txt | 43 +++++++++++++++++++++++++++++++ 4 files changed, 67 insertions(+), 2 deletions(-) create mode 100644 rlp/rlpgen/testdata/alias.in.txt create mode 100644 rlp/rlpgen/testdata/alias.out.txt diff --git a/rlp/rlpgen/gen.go b/rlp/rlpgen/gen.go index 150797c7aa5..7ec38a4c38f 100644 --- a/rlp/rlpgen/gen.go +++ b/rlp/rlpgen/gen.go @@ -673,7 +673,7 @@ func (op sliceOp) genDecode(ctx *genContext) (string, string) { } func (bctx *buildContext) makeOp(name *types.Named, typ types.Type, tags rlpstruct.Tags) (op, error) { - switch typ := typ.(type) { + switch typ := types.Unalias(typ).(type) { case *types.Named: if isBigInt(typ) { return bigIntOp{}, nil diff --git a/rlp/rlpgen/gen_test.go b/rlp/rlpgen/gen_test.go index 3b4f5df2876..be439902610 100644 --- a/rlp/rlpgen/gen_test.go +++ b/rlp/rlpgen/gen_test.go @@ -47,7 +47,7 @@ func init() { } } -var tests = []string{"uints", "nil", "rawvalue", "optional", "bigint", "uint256"} +var tests = []string{"uints", "nil", "rawvalue", "optional", "bigint", "uint256", "alias"} func TestOutput(t *testing.T) { for _, test := range tests { diff --git a/rlp/rlpgen/testdata/alias.in.txt b/rlp/rlpgen/testdata/alias.in.txt new file mode 100644 index 00000000000..c7aa8a3106f --- /dev/null +++ b/rlp/rlpgen/testdata/alias.in.txt @@ -0,0 +1,22 @@ +// -*- mode: go -*- + +package test + +import ( + "math/big" + "github.com/holiman/uint256" +) + +// Alias types chosen because their originals have special handling that is easy +// to spot when inspecting generated output. +type ( + Big = big.Int + // Demonstrate recursive unaliasing + intermediate = uint256.Int + Uint256 = intermediate +) + +type Test struct { + BigAlias Big + Uint256Alias Uint256 +} diff --git a/rlp/rlpgen/testdata/alias.out.txt b/rlp/rlpgen/testdata/alias.out.txt new file mode 100644 index 00000000000..0746f974946 --- /dev/null +++ b/rlp/rlpgen/testdata/alias.out.txt @@ -0,0 +1,43 @@ +package test + +import "github.com/ava-labs/libevm/rlp" +import "github.com/holiman/uint256" +import "io" + +func (obj *Test) EncodeRLP(_w io.Writer) error { + w := rlp.NewEncoderBuffer(_w) + _tmp0 := w.List() + if obj.BigAlias.Sign() == -1 { + return rlp.ErrNegativeBigInt + } + w.WriteBigInt(&obj.BigAlias) + w.WriteUint256(&obj.Uint256Alias) + w.ListEnd(_tmp0) + return w.Flush() +} + +func (obj *Test) DecodeRLP(dec *rlp.Stream) error { + var _tmp0 Test + { + if _, err := dec.List(); err != nil { + return err + } + // BigAlias: + _tmp1, err := dec.BigInt() + if err != nil { + return err + } + _tmp0.BigAlias = (*_tmp1) + // Uint256Alias: + var _tmp2 uint256.Int + if err := dec.ReadUint256(&_tmp2); err != nil { + return err + } + _tmp0.Uint256Alias = _tmp2 + if err := dec.ListEnd(); err != nil { + return err + } + } + *obj = _tmp0 + return nil +} From 4c6e50e7d15795d2d435c53b9dcfc2d02325437d Mon Sep 17 00:00:00 2001 From: Arran Schlosberg <519948+ARR4N@users.noreply.github.com> Date: Fri, 7 Mar 2025 13:23:11 +0000 Subject: [PATCH 095/142] chore: module-renaming workflow inverts between `libevm` and `geth` (#152) ## Why this should be merged Originally I'd planned on doing an upstream sync by running the rename workflow on the incoming commit and then merging it to `main` however this resulted in hundreds of merge commits that were solely due to Go imports. Renaming the module from `ava-labs/libevm` to `ethereum/go-ethereum` removed 90% of conflicts (H/T @darioush). The module will then need to be named `ava-labs/libevm` again, so the commit history will probably[^1] look like this after an update: ```mermaid --- config: gitGraph: mainBranchName: main parallelCommits: true --- gitGraph TB: branch geth order:2 commit id:"geth@v1.15.2" checkout main commit id:"libevm@v1.13.14" branch sync/v1.15.2 commit id:"[AUTO] rename to ethereum/go-ethereum" merge geth commit id:"[AUTO] rename to ava-labs/libevm" checkout main merge sync/v1.15.2 id:"libevm@v1.15.2" ``` [^1]: Specifics of and rationale behind the merge strategy are beyond the scope of this PR. ## How this works The current module name is determined with `go list -m` and the rename from/to patterns are no longer hard-coded. ## How this was tested Inspection of runs and resulting branch. Although these were the bc8e5015694707ff682c444afff52a3801b35a53 workflow, the only other commit in this PR is cosmetic (as seen in [this run](https://github.com/ava-labs/libevm/actions/runs/13433886428) to create f2cecaff9c01c86053644aafc9b7196229a84cbc). 1.

of only cherry-picking on release branches made the `main` branch incompatible with dependent repos. ## How this works The goal of the old strategy was to avoid cherry-picking on the same branch to which we would later merge the duplicated, upstream commit. This can instead be achieved by tracking the cherry-picked commits and reverting them as part of the geth sync. Since we already do this for our own changes and a single cherry-pick (see #128), there's no need to use the two approaches simultaneously. This PR deletes the cherry-picking mechanism and removes the release-branch test that enforced its proper usage. It will be followed up by a series of PRs, one per cherry-pick that would have otherwise been placed on release branches. ## How this was tested n/a --- libevm/tooling/go.mod | 1 - libevm/tooling/release/cherrypick.sh | 47 -------- libevm/tooling/release/cherrypicks | 15 --- libevm/tooling/release/release_test.go | 151 +------------------------ 4 files changed, 4 insertions(+), 210 deletions(-) delete mode 100755 libevm/tooling/release/cherrypick.sh delete mode 100644 libevm/tooling/release/cherrypicks diff --git a/libevm/tooling/go.mod b/libevm/tooling/go.mod index a0edc3e00ae..ba183372060 100644 --- a/libevm/tooling/go.mod +++ b/libevm/tooling/go.mod @@ -7,7 +7,6 @@ replace github.com/ava-labs/libevm => ../../ require ( github.com/ava-labs/libevm v0.0.0-00010101000000-000000000000 github.com/go-git/go-git/v5 v5.14.0 - github.com/google/go-cmp v0.7.0 github.com/stretchr/testify v1.10.0 ) diff --git a/libevm/tooling/release/cherrypick.sh b/libevm/tooling/release/cherrypick.sh deleted file mode 100755 index c9100a39855..00000000000 --- a/libevm/tooling/release/cherrypick.sh +++ /dev/null @@ -1,47 +0,0 @@ -#!/usr/bin/env bash - -# Copyright 2025 the libevm authors. -# -# The libevm additions to go-ethereum are free software: you can redistribute -# them and/or modify them under the terms of the GNU Lesser General Public License -# as published by the Free Software Foundation, either version 3 of the License, -# or (at your option) any later version. -# -# The libevm additions are distributed in the hope that they will be useful, -# but WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Once consumed gas is no longer changing (i.e. after all spends and refunds), the transaction limit is passed to the hook to determine the minimum consumption, which is applied. ## How this was tested Unit test via `core.ApplyTransaction()` as this is our entry point in SAE. --------- Signed-off-by: Arran Schlosberg <519948+ARR4N@users.noreply.github.com> Co-authored-by: Stephen Buttolph --- core/state_transition.go | 2 + core/state_transition.libevm.go | 30 +++++- core/state_transition.libevm_test.go | 146 +++++++++++++++++++++++++++ libevm/hookstest/stub.go | 10 ++ params/hooks.libevm.go | 11 ++ 5 files changed, 195 insertions(+), 4 deletions(-) diff --git a/core/state_transition.go b/core/state_transition.go index 509403be610..f588a649e48 100644 --- a/core/state_transition.go +++ b/core/state_transition.go @@ -478,6 +478,8 @@ func (st *StateTransition) refundGas(refundQuotient uint64) uint64 { } st.gasRemaining += refund + st.consumeMinimumGas() // libevm: see comment on method re call-site requirements + // Return ETH for remaining gas, exchanged at the original rate. remaining := uint256.NewInt(st.gasRemaining) remaining = remaining.Mul(remaining, uint256.MustFromBig(st.msg.GasPrice)) diff --git a/core/state_transition.libevm.go b/core/state_transition.libevm.go index 701cc4d5ee7..bb9c3eff469 100644 --- a/core/state_transition.libevm.go +++ b/core/state_transition.libevm.go @@ -18,22 +18,44 @@ package core import ( "github.com/ava-labs/libevm/log" + "github.com/ava-labs/libevm/params" ) +func (st *StateTransition) rulesHooks() params.RulesHooks { + bCtx := st.evm.Context + rules := st.evm.ChainConfig().Rules(bCtx.BlockNumber, bCtx.Random != nil, bCtx.Time) + return rules.Hooks() +} + // canExecuteTransaction is a convenience wrapper for calling the // [params.RulesHooks.CanExecuteTransaction] hook. func (st *StateTransition) canExecuteTransaction() error { - bCtx := st.evm.Context - rules := st.evm.ChainConfig().Rules(bCtx.BlockNumber, bCtx.Random != nil, bCtx.Time) - if err := rules.Hooks().CanExecuteTransaction(st.msg.From, st.msg.To, st.state); err != nil { + hooks := st.rulesHooks() + if err := hooks.CanExecuteTransaction(st.msg.From, st.msg.To, st.state); err != nil { log.Debug( "Transaction execution blocked by libevm hook", "from", st.msg.From, "to", st.msg.To, - "hooks", log.TypeOf(rules.Hooks()), + "hooks", log.TypeOf(hooks), "reason", err, ) return err } return nil } + +// consumeMinimumGas updates the gas remaining to reflect the value returned by +// [params.RulesHooks.MinimumGasConsumption].

This change allows arbitrary types to be sent to `triedb` as well as the `SnapshotTree`.

2024-11-04 + +#### Added + - New module `musig` implements the MuSig2 multisignature scheme according to the [BIP 327 specification](https://github.com/bitcoin/bips/blob/master/bip-0327.mediawiki). See: + - Header file `include/secp256k1_musig.h` which defines the new API. + - Document `doc/musig.md` for further notes on API usage. + - Usage example `examples/musig.c`. + - New CMake variable `SECP256K1_APPEND_LDFLAGS` for appending linker flags to the build command. + +#### Changed + - API functions now use a significantly more robust method to clear secrets from the stack before returning. However, secret clearing remains a best-effort security measure and cannot guarantee complete removal. + - Any type `secp256k1_foo` can now be forward-declared using `typedef struct secp256k1_foo secp256k1_foo;` (or also `struct secp256k1_foo;` in C++). + - Organized CMake build artifacts into dedicated directories (`bin/` for executables, `lib/` for libraries) to improve build output structure and Windows shared library compatibility. + +#### Removed + - Removed the `secp256k1_scratch_space` struct and its associated functions `secp256k1_scratch_space_create` and `secp256k1_scratch_space_destroy` because the scratch space was unused in the API. + +#### ABI Compatibility +The symbols `secp256k1_scratch_space_create` and `secp256k1_scratch_space_destroy` were removed. +Otherwise, the library maintains backward compatibility with versions 0.3.x through 0.5.x. + +## [0.5.1] - 2024-08-01 + +#### Added + - Added usage example for an ElligatorSwift key exchange. + +#### Changed + - The default size of the precomputed table for signing was changed from 22 KiB to 86 KiB. The size can be changed with the configure option `--ecmult-gen-kb` (`SECP256K1_ECMULT_GEN_KB` for CMake). + - "auto" is no longer an accepted value for the `--with-ecmult-window` and `--with-ecmult-gen-kb` configure options (this also applies to `SECP256K1_ECMULT_WINDOW_SIZE` and `SECP256K1_ECMULT_GEN_KB` in CMake). To achieve the same configuration as previously provided by the "auto" value, omit setting the configure option explicitly. + +#### Fixed + - Fixed compilation when the extrakeys module is disabled. + +#### ABI Compatibility +The ABI is backward compatible with versions 0.5.0, 0.4.x and 0.3.x. + +## [0.5.0] - 2024-05-06 + +#### Added + - New function `secp256k1_ec_pubkey_sort` that sorts public keys using lexicographic (of compressed serialization) order. + +#### Changed + - The implementation of the point multiplication algorithm used for signing and public key generation was changed, resulting in improved performance for those operations. + - The related configure option `--ecmult-gen-precision` was replaced with `--ecmult-gen-kb` (`SECP256K1_ECMULT_GEN_KB` for CMake). + - This changes the supported precomputed table sizes for these operations. The new supported sizes are 2 KiB, 22 KiB, or 86 KiB (while the old supported sizes were 32 KiB, 64 KiB, or 512 KiB). + +#### ABI Compatibility +The ABI is backward compatible with versions 0.4.x and 0.3.x. + +## [0.4.1] - 2023-12-21 + +#### Changed + - The point multiplication algorithm used for ECDH operations (module `ecdh`) was replaced with a slightly faster one. + - Optional handwritten x86_64 assembly for field operations was removed because modern C compilers are able to output more efficient assembly. This change results in a significant speedup of some library functions when handwritten x86_64 assembly is enabled (`--with-asm=x86_64` in GNU Autotools, `-DSECP256K1_ASM=x86_64` in CMake), which is the default on x86_64. Benchmarks with GCC 10.5.0 show a 10% speedup for `secp256k1_ecdsa_verify` and `secp256k1_schnorrsig_verify`. + +#### ABI Compatibility +The ABI is backward compatible with versions 0.4.0 and 0.3.x. + +## [0.4.0] - 2023-09-04 + +#### Added + - New module `ellswift` implements ElligatorSwift encoding for public keys and x-only Diffie-Hellman key exchange for them. + ElligatorSwift permits representing secp256k1 public keys as 64-byte arrays which cannot be distinguished from uniformly random. See: + - Header file `include/secp256k1_ellswift.h` which defines the new API. + - Document `doc/ellswift.md` which explains the mathematical background of the scheme. + - The [paper](https://eprint.iacr.org/2022/759) on which the scheme is based. + - We now test the library with unreleased development snapshots of GCC and Clang. This gives us an early chance to catch miscompilations and constant-time issues introduced by the compiler (such as those that led to the previous two releases). + +#### Fixed + - Fixed symbol visibility in Windows DLL builds, where three internal library symbols were wrongly exported. + +#### Changed + - When consuming libsecp256k1 as a static library on Windows, the user must now define the `SECP256K1_STATIC` macro before including `secp256k1.h`. + +#### ABI Compatibility +This release is backward compatible with the ABI of 0.3.0, 0.3.1, and 0.3.2. Symbol visibility is now believed to be handled properly on supported platforms and is now considered to be part of the ABI. Please report any improperly exported symbols as a bug. + +## [0.3.2] - 2023-05-13 +We strongly recommend updating to 0.3.2 if you use or plan to use GCC >=13 to compile libsecp256k1. When in doubt, check the GCC version using `gcc -v`. + +#### Security + - Module `ecdh`: Fix "constant-timeness" issue with GCC 13.1 (and potentially future versions of GCC) that could leave applications using libsecp256k1's ECDH module vulnerable to a timing side-channel attack. The fix avoids secret-dependent control flow during ECDH computations when libsecp256k1 is compiled with GCC 13.1. + +#### Fixed + - Fixed an old bug that permitted compilers to potentially output bad assembly code on x86_64. In theory, it could lead to a crash or a read of unrelated memory, but this has never been observed on any compilers so far. + +#### Changed + - Various improvements and changes to CMake builds. CMake builds remain experimental. + - Made API versioning consistent with GNU Autotools builds. + - Switched to `BUILD_SHARED_LIBS` variable for controlling whether to build a static or a shared library. + - Added `SECP256K1_INSTALL` variable for the controlling whether to install the build artefacts. + - Renamed asm build option `arm` to `arm32`. Use `--with-asm=arm32` instead of `--with-asm=arm` (GNU Autotools), and `-DSECP256K1_ASM=arm32` instead of `-DSECP256K1_ASM=arm` (CMake). + +#### ABI Compatibility +The ABI is compatible with versions 0.3.0 and 0.3.1. + +## [0.3.1] - 2023-04-10 +We strongly recommend updating to 0.3.1 if you use or plan to use Clang >=14 to compile libsecp256k1, e.g., Xcode >=14 on macOS has Clang >=14. When in doubt, check the Clang version using `clang -v`. + +#### Security + - Fix "constant-timeness" issue with Clang >=14 that could leave applications using libsecp256k1 vulnerable to a timing side-channel attack. The fix avoids secret-dependent control flow and secret-dependent memory accesses in conditional moves of memory objects when libsecp256k1 is compiled with Clang >=14. + +#### Added + - Added tests against [Project Wycheproof's](https://github.com/google/wycheproof/) set of ECDSA test vectors (Bitcoin "low-S" variant), a fixed set of test cases designed to trigger various edge cases. + +#### Changed + - Increased minimum required CMake version to 3.13. CMake builds remain experimental. + +#### ABI Compatibility +The ABI is compatible with version 0.3.0. + +## [0.3.0] - 2023-03-08 + +#### Added + - Added experimental support for CMake builds. Traditional GNU Autotools builds (`./configure` and `make`) remain fully supported. + - Usage examples: Added a recommended method for securely clearing sensitive data, e.g., secret keys, from memory. + - Tests: Added a new test binary `noverify_tests`. This binary runs the tests without some additional checks present in the ordinary `tests` binary and is thereby closer to production binaries. The `noverify_tests` binary is automatically run as part of the `make check` target. + +#### Fixed + - Fixed declarations of API variables for MSVC (`__declspec(dllimport)`). This fixes MSVC builds of programs which link against a libsecp256k1 DLL dynamically and use API variables (and not only API functions). Unfortunately, the MSVC linker now will emit warning `LNK4217` when trying to link against libsecp256k1 statically. Pass `/ignore:4217` to the linker to suppress this warning. + +#### Changed + - Forbade cloning or destroying `secp256k1_context_static`. Create a new context instead of cloning the static context. (If this change breaks your code, your code is probably wrong.) + - Forbade randomizing (copies of) `secp256k1_context_static`. Randomizing a copy of `secp256k1_context_static` did not have any effect and did not provide defense-in-depth protection against side-channel attacks. Create a new context if you want to benefit from randomization. + +#### Removed + - Removed the configuration header `src/libsecp256k1-config.h`. We recommend passing flags to `./configure` or `cmake` to set configuration options (see `./configure --help` or `cmake -LH`). If you cannot or do not want to use one of the supported build systems, pass configuration flags such as `-DSECP256K1_ENABLE_MODULE_SCHNORRSIG` manually to the compiler (see the file `configure.ac` for supported flags). + +#### ABI Compatibility +Due to changes in the API regarding `secp256k1_context_static` described above, the ABI is *not* compatible with previous versions. + +## [0.2.0] - 2022-12-12 + +#### Added + - Added usage examples for common use cases in a new `examples/` directory. + - Added `secp256k1_selftest`, to be used in conjunction with `secp256k1_context_static`. + - Added support for 128-bit wide multiplication on MSVC for x86_64 and arm64, giving roughly a 20% speedup on those platforms. + +#### Changed + - Enabled modules `schnorrsig`, `extrakeys` and `ecdh` by default in `./configure`. + - The `secp256k1_nonce_function_rfc6979` nonce function, used by default by `secp256k1_ecdsa_sign`, now reduces the message hash modulo the group order to match the specification. This only affects improper use of ECDSA signing API. + +#### Deprecated + - Deprecated context flags `SECP256K1_CONTEXT_VERIFY` and `SECP256K1_CONTEXT_SIGN`. Use `SECP256K1_CONTEXT_NONE` instead. + - Renamed `secp256k1_context_no_precomp` to `secp256k1_context_static`. + - Module `schnorrsig`: renamed `secp256k1_schnorrsig_sign` to `secp256k1_schnorrsig_sign32`. + +#### ABI Compatibility +Since this is the first release, we do not compare application binary interfaces. +However, there are earlier unreleased versions of libsecp256k1 that are *not* ABI compatible with this version. + +## [0.1.0] - 2013-03-05 to 2021-12-25 + +This version was in fact never released. +The number was given by the build system since the introduction of autotools in Jan 2014 (ea0fe5a5bf0c04f9cc955b2966b614f5f378c6f6). +Therefore, this version number does not uniquely identify a set of source files. + +[unreleased]: https://github.com/bitcoin-core/secp256k1/compare/v0.6.0...HEAD +[0.6.0]: https://github.com/bitcoin-core/secp256k1/compare/v0.5.1...v0.6.0 +[0.5.1]: https://github.com/bitcoin-core/secp256k1/compare/v0.5.0...v0.5.1 +[0.5.0]: https://github.com/bitcoin-core/secp256k1/compare/v0.4.1...v0.5.0 +[0.4.1]: https://github.com/bitcoin-core/secp256k1/compare/v0.4.0...v0.4.1 +[0.4.0]: https://github.com/bitcoin-core/secp256k1/compare/v0.3.2...v0.4.0 +[0.3.2]: https://github.com/bitcoin-core/secp256k1/compare/v0.3.1...v0.3.2 +[0.3.1]: https://github.com/bitcoin-core/secp256k1/compare/v0.3.0...v0.3.1 +[0.3.0]: https://github.com/bitcoin-core/secp256k1/compare/v0.2.0...v0.3.0 +[0.2.0]: https://github.com/bitcoin-core/secp256k1/compare/423b6d19d373f1224fd671a982584d7e7900bc93..v0.2.0 +[0.1.0]: https://github.com/bitcoin-core/secp256k1/commit/423b6d19d373f1224fd671a982584d7e7900bc93 diff --git a/crypto/secp256k1/libsecp256k1/CMakeLists.txt b/crypto/secp256k1/libsecp256k1/CMakeLists.txt new file mode 100644 index 00000000000..aba6e512592 --- /dev/null +++ b/crypto/secp256k1/libsecp256k1/CMakeLists.txt @@ -0,0 +1,405 @@ +cmake_minimum_required(VERSION 3.16) + +#============================= +# Project / Package metadata +#============================= +project(libsecp256k1 + # The package (a.k.a. release) version is based on semantic versioning 2.0.0 of + # the API.

Moreover, it should be possible to use the library without any heap allocations. +* The tests should cover all lines and branches of the library (see [Test coverage](#coverage)). +* Operations involving secret data should be tested for being constant time with respect to the secrets (see [src/ctime_tests.c](src/ctime_tests.c)). +* Local variables containing secret data should be cleared explicitly to try to delete secrets from memory. +* Use `secp256k1_memcmp_var` instead of `memcmp` (see [#823](https://github.com/bitcoin-core/secp256k1/issues/823)). +* As a rule of thumb, the default values for configuration options should target standard desktop machines and align with Bitcoin Core's defaults, and the tests should mostly exercise the default configuration (see [#1549](https://github.com/bitcoin-core/secp256k1/issues/1549#issuecomment-2200559257)). + +#### Style conventions + +* Commits should be atomic and diffs should be easy to read. For this reason, do not mix any formatting fixes or code moves with actual code changes. Make sure each individual commit is hygienic: that it builds successfully on its own without warnings, errors, regressions, or test failures. +* New code should adhere to the style of existing, in particular surrounding, code. Other than that, we do not enforce strict rules for code formatting. +* The code conforms to C89. Most notably, that means that only `/* ... */` comments are allowed (no `//` line comments). Moreover, any declarations in a `{ ... }` block (e.g., a function) must appear at the beginning of the block before any statements. When you would like to declare a variable in the middle of a block, you can open a new block: + ```C + void secp256k_foo(void) { + unsigned int x; /* declaration */ + int y = 2*x; /* declaration */ + x = 17; /* statement */ + { + int a, b; /* declaration */ + a = x + y; /* statement */ + secp256k_bar(x, &b); /* statement */ + } + } + ``` +* Use `unsigned int` instead of just `unsigned`. +* Use `void *ptr` instead of `void* ptr`. +* Arguments of the publicly-facing API must have a specific order defined in [include/secp256k1.h](include/secp256k1.h). +* User-facing comment lines in headers should be limited to 80 chars if possible. +* All identifiers in file scope should start with `secp256k1_`. +* Avoid trailing whitespace. +* Use the constants `EXIT_SUCCESS`/`EXIT_FAILURE` (defined in `stdlib.h`) to indicate program execution status for examples and other binaries. + +### Tests + +#### Coverage + +This library aims to have full coverage of reachable lines and branches. + +To create a test coverage report, configure with `--enable-coverage` (use of GCC is necessary): + + $ ./configure --enable-coverage + +Run the tests: + + $ make check + +To create a report, `gcovr` is recommended, as it includes branch coverage reporting: + + $ gcovr --exclude 'src/bench*' --print-summary + +To create a HTML report with coloured and annotated source code: + + $ mkdir -p coverage + $ gcovr --exclude 'src/bench*' --html --html-details -o coverage/coverage.html + +#### Exhaustive tests + +There are tests of several functions in which a small group replaces secp256k1. +These tests are *exhaustive* since they provide all elements and scalars of the small group as input arguments (see [src/tests_exhaustive.c](src/tests_exhaustive.c)). + +### Benchmarks + +See `src/bench*.c` for

Introduction + +The `ellswift` module effectively introduces a new 64-byte public key format, with the property +that (uniformly random) public keys can be encoded as 64-byte arrays which are computationally +indistinguishable from uniform byte arrays. The module provides functions to convert public keys +from and to this format, as well as convenience functions for key generation and ECDH that operate +directly on ellswift-encoded keys. + +The encoding consists of the concatenation of two (32-byte big endian) encoded field elements $u$ +and $t.$ Together they encode an x-coordinate on the curve $x$, or (see further) a full point $(x, y)$ on +the curve. + +**Decoding** consists of decoding the field elements $u$ and $t$ (values above the field size $p$ +are taken modulo $p$), and then evaluating $F_u(t)$, which for every $u$ and $t$ results in a valid +x-coordinate on the curve. The functions $F_u$ will be defined in [Section 2](#2-the-decoding-function). + +**Encoding** a given $x$ coordinate is conceptually done as follows: +* Loop: + * Pick a uniformly random field element $u.$ + * Compute the set $L = F_u^{-1}(x)$ of $t$ values for which $F_u(t) = x$, which may have up to *8* elements. + * With probability $1 - \dfrac{\\#L}{8}$, restart the loop. + * Select a uniformly random $t \in L$ and return $(u, t).$ + +This is the *ElligatorSwift* algorithm, here given for just x-coordinates. An extension to full +$(x, y)$ points will be given in [Section 4](#4-encoding-and-decoding-full-x-y-coordinates). +The algorithm finds a uniformly random $(u, t)$ among (almost all) those +for which $F_u(t) = x.$ Section 3.2 in the paper proves that the number of such encodings for +almost all x-coordinates on the curve (all but at most 39) is close to two times the field size +(specifically, it lies in the range $2q \pm (22\sqrt{q} + O(1))$, where $q$ is the size of the field). + +## 2. The decoding function + +First some definitions: +* $\mathbb{F}$ is the finite field of size $q$, of characteristic 5 or more, and $q \equiv 1 \mod 3.$ + * For `secp256k1`, $q = 2^{256} - 2^{32} - 977$, which satisfies that requirement. +* Let $E$ be the elliptic curve of points $(x, y) \in \mathbb{F}^2$ for which $y^2 = x^3 + ax + b$, with $a$ and $b$ + public constants, for which $\Delta_E = -16(4a^3 + 27b^2)$ is a square, and at least one of $(-b \pm \sqrt{-3 \Delta_E} / 36)/2$ is a square. + This implies that the order of $E$ is either odd, or a multiple of *4*. + If $a=0$, this condition is always fulfilled. + * For `secp256k1`, $a=0$ and $b=7.$ +* Let the function $g(x) = x^3 + ax + b$, so the $E$ curve equation is also $y^2 = g(x).$ +* Let the function $h(x) = 3x^3 + 4a.$ +* Define $V$ as the set of solutions $(x_1, x_2, x_3, z)$ to $z^2 = g(x_1)g(x_2)g(x_3).$ +* Define $S_u$ as the set of solutions $(X, Y)$ to $X^2 + h(u)Y^2 = -g(u)$ and $Y \neq 0.$ +* $P_u$ is a function from $\mathbb{F}$ to $S_u$ that will be defined below. +* $\psi_u$ is a function from $S_u$ to $V$ that will be defined below. + +**Note**: In the paper: +* $F_u$ corresponds to $F_{0,u}$ there. +* $P_u(t)$ is called $P$ there. +* All $S_u$ sets together correspond to $S$ there. +* All $\psi_u$ functions together (operating on elements of $S$) correspond to $\psi$ there. + +Note that for $V$, the left hand side of the equation $z^2$ is square, and thus the right +hand must also be square. As multiplying non-squares results in a square in $\mathbb{F}$, +out of the three right-hand side factors an even number must be non-squares. +This implies that exactly *1* or exactly *3* out of +$\\{g(x_1), g(x_2), g(x_3)\\}$ must be square, and thus that for any $(x_1,x_2,x_3,z) \in V$, +at least one of $\\{x_1, x_2, x_3\\}$ must be a valid x-coordinate on $E.$ There is one exception +to this, namely when $z=0$, but even then one of the three values is a valid x-coordinate. + +**Define** the decoding function $F_u(t)$ as: +* Let $(x_1, x_2, x_3, z) = \psi_u(P_u(t)).$ +* Return the first element $x$ of $(x_3, x_2, x_1)$ which is a valid x-coordinate on $E$ (i.e., $g(x)$ is square). + +$P_u(t) = (X(u, t), Y(u, t))$, where: + +$$ +\begin{array}{lcl} +X(u, t) & = & \left\\{\begin{array}{ll} + \dfrac{g(u) - t^2}{2t} & a = 0 \\ + \dfrac{g(u) + h(u)(Y_0(u) - X_0(u)t)^2}{X_0(u)(1 + h(u)t^2)} & a \neq 0 +\end{array}\right. \\ +Y(u, t) & = & \left\\{\begin{array}{ll} + \dfrac{X(u, t) + t}{u \sqrt{-3}} = \dfrac{g(u) + t^2}{2tu\sqrt{-3}} & a = 0 \\ + Y_0(u) + t(X(u, t) - X_0(u)) & a \neq 0 +\end{array}\right. +\end{array} +$$ + +$P_u(t)$ is defined: +* For $a=0$, unless: + * $u = 0$ or $t = 0$ (division by zero) + * $g(u) = -t^2$ (would give $Y=0$). +* For $a \neq 0$, unless: + * $X_0(u) = 0$ or $h(u)t^2 = -1$ (division by zero) + * $Y_0(u) (1 - h(u)t^2) = 2X_0(u)t$ (would give $Y=0$). + +The functions $X_0(u)$ and $Y_0(u)$ are defined in Appendix A of the paper, and depend on various properties of $E.$ + +The function $\psi_u$ is the same for all curves: $\psi_u(X, Y) = (x_1, x_2, x_3, z)$, where: + +$$ +\begin{array}{lcl} + x_1 & = & \dfrac{X}{2Y} - \dfrac{u}{2} && \\ + x_2 & = & -\dfrac{X}{2Y} - \dfrac{u}{2} && \\ + x_3 & = & u + 4Y^2 && \\ + z & = & \dfrac{g(x_3)}{2Y}(u^2 + ux_1 + x_1^2 + a) = \dfrac{-g(u)g(x_3)}{8Y^3} +\end{array} +$$ + +### 2.1 Decoding for `secp256k1` + +Put together and specialized for $a=0$ curves, decoding $(u, t)$ to an x-coordinate is: + +**Define** $F_u(t)$ as: +* Let $X = \dfrac{u^3 + b - t^2}{2t}.$ +* Let $Y = \dfrac{X + t}{u\sqrt{-3}}.$ +* Return the first $x$ in $(u + 4Y^2, \dfrac{-X}{2Y} - \dfrac{u}{2}, \dfrac{X}{2Y} - \dfrac{u}{2})$ for which $g(x)$ is square. + +To make sure that every input decodes to a valid x-coordinate, we remap the inputs in case +$P_u$ is not defined (when $u=0$, $t=0$, or $g(u) = -t^2$): + +**Define** $F_u(t)$ as: +* Let $u'=u$ if $u \neq 0$; $1$ otherwise (guaranteeing $u' \neq 0$). +* Let $t'=t$ if $t \neq 0$; $1$ otherwise (guaranteeing $t' \neq 0$). +* Let $t''=t'$ if $g(u') \neq -t'^2$; $2t'$ otherwise (guaranteeing $t'' \neq 0$ and $g(u') \neq -t''^2$). +* Let $X = \dfrac{u'^3 + b - t''^2}{2t''}.$ +* Let $Y = \dfrac{X + t''}{u'\sqrt{-3}}.$ +* Return the first $x$ in $(u' + 4Y^2, \dfrac{-X}{2Y} - \dfrac{u'}{2}, \dfrac{X}{2Y} - \dfrac{u'}{2})$ for which $x^3 + b$ is square. + +The choices here are not strictly necessary. Just returning a fixed constant in any of the undefined cases would suffice, +but the approach here is simple enough and gives fairly uniform output even in these cases. + +**Note**: in the paper these conditions result in $\infty$ as output, due to the use of projective coordinates there. +We wish to avoid the need for callers to deal with this special case. + +This is implemented in `secp256k1_ellswift_xswiftec_frac_var` (which decodes to an x-coordinate represented as a fraction), and +in `secp256k1_ellswift_xswiftec_var` (which outputs the actual x-coordinate). + +## 3. The encoding function + +To implement $F_u^{-1}(x)$, the function to find the set of inverses $t$ for which $F_u(t) = x$, we have to reverse the process: +* Find all the $(X, Y) \in S_u$ that could have given rise to $x$, through the $x_1$, $x_2$, or $x_3$ formulas in $\psi_u.$ +* Map those $(X, Y)$ solutions to $t$ values using $P_u^{-1}(X, Y).$ +* For each of the found $t$ values, verify that $F_u(t) = x.$ +* Return the remaining $t$ values. + +The function $P_u^{-1}$, which finds $t$ given $(X, Y) \in S_u$, is significantly simpler than $P_u:$ + +$$ +P_u^{-1}(X, Y) = \left\\{\begin{array}{ll} +Yu\sqrt{-3} - X & a = 0 \\ +\dfrac{Y-Y_0(u)}{X-X_0(u)} & a \neq 0 \land X \neq X_0(u) \\ +\dfrac{-X_0(u)}{h(u)Y_0(u)} & a \neq 0 \land X = X_0(u) \land Y = Y_0(u) +\end{array}\right. +$$ + +The third step above, verifying that $F_u(t) = x$, is necessary because for the $(X, Y)$ values found through the $x_1$ and $x_2$ expressions, +it is possible that decoding through $\psi_u(X, Y)$ yields a valid $x_3$ on the curve, which would take precedence over the +$x_1$ or $x_2$ decoding. These $(X, Y)$ solutions must be rejected. + +Since we know that exactly one or exactly three out of $\\{x_1, x_2, x_3\\}$ are valid x-coordinates for any $t$, +the case where either $x_1$ or $x_2$ is valid and in addition also $x_3$ is valid must mean that all three are valid. +This means that instead of checking whether $x_3$ is on the curve, it is also possible to check whether the other one out of +$x_1$ and $x_2$ is on the curve. This is significantly simpler, as it turns out. + +Observe that $\psi_u$ guarantees that $x_1 + x_2 = -u.$ So given either $x = x_1$ or $x = x_2$, the other one of the two can be computed as +$-u - x.$ Thus, when encoding $x$ through the $x_1$ or $x_2$ expressions, one can simply check whether $g(-u-x)$ is a square, +and if so, not include the corresponding $t$ values in the returned set. As this does not need $X$, $Y$, or $t$, this condition can be determined +before those values are computed. + +It is not possible that an encoding found through the $x_1$ expression decodes to a different valid x-coordinate using $x_2$ (which would +take precedence), for the same reason: if both $x_1$ and $x_2$ decodings were valid, $x_3$ would be valid as well, and thus take +precedence over both. Because of this, the $g(-u-x)$ being square test for $x_1$ and $x_2$ is the only test necessary to guarantee the found $t$ +values round-trip back to the input $x$ correctly. This is the reason for choosing the $(x_3, x_2, x_1)$ precedence order in the decoder; +any order which does not place $x_3$ first requires more complicated round-trip checks in the encoder. + +### 3.1 Switching to *v, w* coordinates + +Before working out the formulas for all this, we switch to different variables for $S_u.$ Let $v = (X/Y - u)/2$, and +$w = 2Y.$ Or in the other direction, $X = w(u/2 + v)$ and $Y = w/2:$ +* $S_u'$ becomes the set of $(v, w)$ for which $w^2 (u^2 + uv + v^2 + a) = -g(u)$ and $w \neq 0.$ +* For $a=0$ curves, $P_u^{-1}$ can be stated for $(v,w)$ as $P_u^{'-1}(v, w) = w\left(\frac{\sqrt{-3}-1}{2}u - v\right).$ +* $\psi_u$ can be stated for $(v, w)$ as $\psi_u'(v, w) = (x_1, x_2, x_3, z)$, where + +$$ +\begin{array}{lcl} + x_1 & = & v \\ + x_2 & = & -u - v \\ + x_3 & = & u + w^2 \\ + z & = & \dfrac{g(x_3)}{w}(u^2 + uv + v^2 + a) = \dfrac{-g(u)g(x_3)}{w^3} +\end{array} +$$ + +We can now write the expressions for finding $(v, w)$ given $x$ explicitly, by solving each of the $\\{x_1, x_2, x_3\\}$ +expressions for $v$ or $w$, and using the $S_u'$ equation to find the other variable: +* Assuming $x = x_1$, we find $v = x$ and $w = \pm\sqrt{-g(u)/(u^2 + uv + v^2 + a)}$ (two solutions). +* Assuming $x = x_2$, we find $v = -u-x$ and $w = \pm\sqrt{-g(u)/(u^2 + uv + v^2 + a)}$ (two solutions). +* Assuming $x = x_3$, we find $w = \pm\sqrt{x-u}$ and $v = -u/2 \pm \sqrt{-w^2(4g(u) + w^2h(u))}/(2w^2)$ (four solutions). + +### 3.2 Avoiding computing all inverses + +The *ElligatorSwift* algorithm as stated in Section 1 requires the computation of $L = F_u^{-1}(x)$ (the +set of all $t$ such that $(u, t)$ decode to $x$) in full. This is unnecessary. + +Observe that the procedure of restarting with probability $(1 - \frac{\\#L}{8})$ and otherwise returning a +uniformly random element from $L$ is actually equivalent to always padding $L$ with $\bot$ values up to length 8, +picking a uniformly random element from that, restarting whenever $\bot$ is picked: + +**Define** *ElligatorSwift(x)* as: +* Loop: + * Pick a uniformly random field element $u.$ + * Compute the set $L = F_u^{-1}(x).$ + * Let $T$ be the 8-element vector consisting of the elements of $L$, plus $8 - \\#L$ times $\\{\bot\\}.$ + * Select a uniformly random $t \in T.$ + * If $t \neq \bot$, return $(u, t)$; restart loop otherwise. + +Now notice that the order of elements in $T$ does not matter, as all we do is pick a uniformly +random element in it, so we do not need to have all $\bot$ values at the end. +As we have 8 distinct formulas for finding $(v, w)$ (taking the variants due to $\pm$ into account), +we can associate every index in $T$ with exactly one of those formulas, making sure that: +* Formulas that yield no solutions (due to division by zero or non-existing square roots) or invalid solutions are made to return $\bot.$ +* For the $x_1$ and $x_2$ cases, if $g(-u-x)$ is a square, $\bot$ is returned instead (the round-trip check). +* In case multiple formulas would return the same non- $\bot$ result, all but one of those must be turned into $\bot$ to avoid biasing those. + +The last condition above only occurs with negligible probability for cryptographically-sized curves, but is interesting +to take into account as it allows exhaustive testing in small groups. See [Section 3.4](#34-dealing-with-special-cases) +for an analysis of all the negligible cases. + +If we define $T = (G_{0,u}(x), G_{1,u}(x), \ldots, G_{7,u}(x))$, with each $G_{i,u}$ matching one of the formulas, +the loop can be simplified to only compute one of the inverses instead of all of them: + +**Define** *ElligatorSwift(x)* as: +* Loop: + * Pick a uniformly random field element $u.$ + * Pick a uniformly random integer $c$ in $[0,8).$ + * Let $t = G_{c,u}(x).$ + * If $t \neq \bot$, return $(u, t)$; restart loop otherwise. + +This is implemented in `secp256k1_ellswift_xelligatorswift_var`. + +### 3.3 Finding the inverse + +To implement $G_{c,u}$, we map $c=0$ to the $x_1$ formula, $c=1$ to the $x_2$ formula, and $c=2$ and $c=3$ to the $x_3$ formula. +Those are then repeated as $c=4$ through $c=7$ for the other sign of $w$ (noting that in each formula, $w$ is a square root of some expression). +Ignoring the negligible cases, we get: + +**Define** $G_{c,u}(x)$ as: +* If $c \in \\{0, 1, 4, 5\\}$ (for $x_1$ and $x_2$ formulas): + * If $g(-u-x)$ is square, return $\bot$ (as $x_3$ would be valid and take precedence). + * If $c \in \\{0, 4\\}$ (the $x_1$ formula) let $v = x$, otherwise let $v = -u-x$ (the $x_2$ formula) + * Let $s = -g(u)/(u^2 + uv + v^2 + a)$ (using $s = w^2$ in what follows). +* Otherwise, when $c \in \\{2, 3, 6, 7\\}$ (for $x_3$ formulas): + * Let $s = x-u.$ + * Let $r = \sqrt{-s(4g(u) + sh(u))}.$ + * Let $v = (r/s - u)/2$ if $c \in \\{3, 7\\}$; $(-r/s - u)/2$ otherwise. +* Let $w = \sqrt{s}.$ +* Depending on $c:$ + * If $c \in \\{0, 1, 2, 3\\}:$ return $P_u^{'-1}(v, w).$ + * If $c \in \\{4, 5, 6, 7\\}:$ return $P_u^{'-1}(v, -w).$ + +Whenever a square root of a non-square is taken, $\bot$ is returned; for both square roots this happens with roughly +50% on random inputs. Similarly, when a division by 0 would occur, $\bot$ is returned as well; this will only happen +with negligible probability. A division by 0 in the first branch in fact cannot occur at all, because $u^2 + uv + v^2 + a = 0$ +implies $g(-u-x) = g(x)$ which would mean the $g(-u-x)$ is square condition has triggered +and $\bot$ would have been returned already. + +**Note**: In the paper, the $case$ variable corresponds roughly to the $c$ above, but only takes on 4 possible values (1 to 4). +The conditional negation of $w$ at the end is done randomly, which is equivalent, but makes testing harder. We choose to +have the $G_{c,u}$ be deterministic, and capture all choices in $c.$ + +Now observe that the $c \in \\{1, 5\\}$ and $c \in \\{3, 7\\}$ conditions effectively perform the same $v \rightarrow -u-v$ +transformation. Furthermore, that transformation has no effect on $s$ in the first branch +as $u^2 + ux + x^2 + a = u^2 + u(-u-x) + (-u-x)^2 + a.$ Thus we can extract it out and move it down: + +**Define** $G_{c,u}(x)$ as: +* If $c \in \\{0, 1, 4, 5\\}:$ + * If $g(-u-x)$ is square, return $\bot.$ + * Let $s = -g(u)/(u^2 + ux + x^2 + a).$ + * Let $v = x.$ +* Otherwise, when $c \in \\{2, 3, 6, 7\\}:$ + * Let $s = x-u.$ + * Let $r = \sqrt{-s(4g(u) + sh(u))}.$ + * Let $v = (r/s - u)/2.$ +* Let $w = \sqrt{s}.$ +* Depending on $c:$ + * If $c \in \\{0, 2\\}:$ return $P_u^{'-1}(v, w).$ + * If $c \in \\{1, 3\\}:$ return $P_u^{'-1}(-u-v, w).$ + * If $c \in \\{4, 6\\}:$ return $P_u^{'-1}(v, -w).$ + * If $c \in \\{5, 7\\}:$ return $P_u^{'-1}(-u-v, -w).$ + +This shows there will always be exactly 0, 4, or 8 $t$ values for a given $(u, x)$ input. +There can be 0, 1, or 2 $(v, w)$ pairs before invoking $P_u^{'-1}$, and each results in 4 distinct $t$ values. + +### 3.4 Dealing with special cases + +As mentioned before there are a few cases to deal with which only happen in a negligibly small subset of inputs. +For cryptographically sized fields, if only random inputs are going to be considered, it is unnecessary to deal with these. Still, for completeness +we analyse them here. They generally fall into two categories: cases in which the encoder would produce $t$ values that +do not decode back to $x$ (or at least cannot guarantee that they do), and cases in which the encoder might produce the same +$t$ value for multiple $c$ inputs (thereby biasing that encoding): + +* In the branch for $x_1$ and $x_2$ (where $c \in \\{0, 1, 4, 5\\}$): + * When $g(u) = 0$, we would have $s=w=Y=0$, which is not on $S_u.$ This is only possible on even-ordered curves. + Excluding this also removes the one condition under which the simplified check for $x_3$ on the curve + fails (namely when $g(x_1)=g(x_2)=0$ but $g(x_3)$ is not square). + This does exclude some valid encodings: when both $g(u)=0$ and $u^2+ux+x^2+a=0$ (also implying $g(x)=0$), + the $S_u'$ equation degenerates to $0 = 0$, and many valid $t$ values may exist. Yet, these cannot be targeted uniformly by the + encoder anyway as there will generally be more than 8. + * When $g(x) = 0$, the same $t$ would be produced as in the $x_3$ branch (where $c \in \\{2, 3, 6, 7\\}$) which we give precedence + as it can deal with $g(u)=0$. + This is again only possible on even-ordered curves. +* In the branch for $x_3$ (where $c \in \\{2, 3, 6, 7\\}$): + * When $s=0$, a division by zero would occur. + * When $v = -u-v$ and $c \in \\{3, 7\\}$, the same $t$ would be returned as in the $c \in \\{2, 6\\}$ cases. + It is equivalent to checking whether $r=0$. + This cannot occur in the $x_1$ or $x_2$ branches, as it would trigger the $g(-u-x)$ is square condition. + A similar concern for $w = -w$ does not exist, as $w=0$ is already impossible in both branches: in the first + it requires $g(u)=0$ which is already outlawed on even-ordered curves and impossible on others; in the second it would trigger division by zero. +* Curve-specific special cases also exist that need to be rejected, because they result in $(u,t)$ which is invalid to the decoder, or because of division by zero in the encoder: + * For $a=0$ curves, when $u=0$ or when $t=0$. The latter can only be reached by the encoder when $g(u)=0$, which requires an even-ordered curve. + * For $a \neq 0$ curves, when $X_0(u)=0$, when $h(u)t^2 = -1$, or when $w(u + 2v) = 2X_0(u)$ while also either $w \neq 2Y_0(u)$ or $h(u)=0$. + +**Define** a version of $G_{c,u}(x)$ which deals with all these cases: +* If $a=0$ and $u=0$, return $\bot.$ +* If $a \neq 0$ and $X_0(u)=0$, return $\bot.$ +* If $c \in \\{0, 1, 4, 5\\}:$ + * If $g(u) = 0$ or $g(x) = 0$, return $\bot$ (even curves only). + * If $g(-u-x)$ is square, return $\bot.$ + * Let $s = -g(u)/(u^2 + ux + x^2 + a)$ (cannot cause division by zero). + * Let $v = x.$ +* Otherwise, when $c \in \\{2, 3, 6, 7\\}:$ + * Let $s = x-u.$ + * Let $r = \sqrt{-s(4g(u) + sh(u))}$; return $\bot$ if not square. + * If $c \in \\{3, 7\\}$ and $r=0$, return $\bot.$ + * If $s = 0$, return $\bot.$ + * Let $v = (r/s - u)/2.$ +* Let $w = \sqrt{s}$; return $\bot$ if not square. +* If $a \neq 0$ and $w(u+2v) = 2X_0(u)$ and either $w \neq 2Y_0(u)$ or $h(u) = 0$, return $\bot.$ +* Depending on $c:$ + * If $c \in \\{0, 2\\}$, let $t = P_u^{'-1}(v, w).$ + * If $c \in \\{1, 3\\}$, let $t = P_u^{'-1}(-u-v, w).$ + * If $c \in \\{4, 6\\}$, let $t = P_u^{'-1}(v, -w).$ + * If $c \in \\{5, 7\\}$, let $t = P_u^{'-1}(-u-v, -w).$ +* If $a=0$ and $t=0$, return $\bot$ (even curves only). +* If $a \neq 0$ and $h(u)t^2 = -1$, return $\bot.$ +* Return $t.$ + +Given any $u$, using this algorithm over all $x$ and $c$ values, every $t$ value will be reached exactly once, +for an $x$ for which $F_u(t) = x$ holds, except for these cases that will not be reached: +* All cases where $P_u(t)$ is not defined: + * For $a=0$ curves, when $u=0$, $t=0$, or $g(u) = -t^2.$ + * For $a \neq 0$ curves, when $h(u)t^2 = -1$, $X_0(u) = 0$, or $Y_0(u) (1 - h(u) t^2) = 2X_0(u)t.$ +* When $g(u)=0$, the potentially many $t$ values that decode to an $x$ satisfying $g(x)=0$ using the $x_2$ formula. These were excluded by the $g(u)=0$ condition in the $c \in \\{0, 1, 4, 5\\}$ branch. + +These cases form a negligible subset of all $(u, t)$ for cryptographically sized curves. + +### 3.5 Encoding for `secp256k1` + +Specialized for odd-ordered $a=0$ curves: + +**Define** $G_{c,u}(x)$ as: +* If $u=0$, return $\bot.$ +* If $c \in \\{0, 1, 4, 5\\}:$ + * If $(-u-x)^3 + b$ is square, return $\bot$ + * Let $s = -(u^3 + b)/(u^2 + ux + x^2)$ (cannot cause division by 0). + * Let $v = x.$ +* Otherwise, when $c \in \\{2, 3, 6, 7\\}:$ + * Let $s = x-u.$ + * Let $r = \sqrt{-s(4(u^3 + b) + 3su^2)}$; return $\bot$ if not square. + * If $c \in \\{3, 7\\}$ and $r=0$, return $\bot.$ + * If $s = 0$, return $\bot.$ + * Let $v = (r/s - u)/2.$ +* Let $w = \sqrt{s}$; return $\bot$ if not square. +* Depending on $c:$ + * If $c \in \\{0, 2\\}:$ return $w(\frac{\sqrt{-3}-1}{2}u - v).$ + * If $c \in \\{1, 3\\}:$ return $w(\frac{\sqrt{-3}+1}{2}u + v).$ + * If $c \in \\{4, 6\\}:$ return $w(\frac{-\sqrt{-3}+1}{2}u + v).$ + * If $c \in \\{5, 7\\}:$ return $w(\frac{-\sqrt{-3}-1}{2}u - v).$ + +This is implemented in `secp256k1_ellswift_xswiftec_inv_var`. + +And the x-only ElligatorSwift encoding algorithm is still: + +**Define** *ElligatorSwift(x)* as: +* Loop: + * Pick a uniformly random field element $u.$ + * Pick a uniformly random integer $c$ in $[0,8).$ + * Let $t = G_{c,u}(x).$ + * If $t \neq \bot$, return $(u, t)$; restart loop otherwise. + +Note that this logic does not take the remapped $u=0$, $t=0$, and $g(u) = -t^2$ cases into account; it just avoids them. +While it is not impossible to make the encoder target them, this would increase the maximum number of $t$ values for a given $(u, x)$ +combination beyond 8, and thereby slow down the ElligatorSwift loop proportionally, for a negligible gain in uniformity. + +## 4. Encoding and decoding full *(x, y)* coordinates + +So far we have only addressed encoding and decoding x-coordinates, but in some cases an encoding +for full points with $(x, y)$ coordinates is desirable. It is possible to encode this information +in $t$ as well. + +Note that for any $(X, Y) \in S_u$, $(\pm X, \pm Y)$ are all on $S_u.$ Moreover, all of these are +mapped to the same x-coordinate. Negating $X$ or negating $Y$ just results in $x_1$ and $x_2$ +being swapped, and does not affect $x_3.$ This will not change the outcome x-coordinate as the order +of $x_1$ and $x_2$ only matters if both were to be valid, and in that case $x_3$ would be used instead. + +Still, these four $(X, Y)$ combinations all correspond to distinct $t$ values, so we can encode +the sign of the y-coordinate in the sign of $X$ or the sign of $Y.$ They correspond to the +four distinct $P_u^{'-1}$ calls in the definition of $G_{u,c}.$ + +**Note**: In the paper, the sign of the y coordinate is encoded in a separately-coded bit. + +To encode the sign of $y$ in the sign of $Y:$ + +**Define** *Decode(u, t)* for full $(x, y)$ as: +* Let $(X, Y) = P_u(t).$ +* Let $x$ be the first value in $(u + 4Y^2, \frac{-X}{2Y} - \frac{u}{2}, \frac{X}{2Y} - \frac{u}{2})$ for which $g(x)$ is square. +* Let $y = \sqrt{g(x)}.$ +* If $sign(y) = sign(Y)$, return $(x, y)$; otherwise return $(x, -y).$ + +And encoding would be done using a $G_{c,u}(x, y)$ function defined as: + +**Define** $G_{c,u}(x, y)$ as: +* If $c \in \\{0, 1\\}:$ + * If $g(u) = 0$ or $g(x) = 0$, return $\bot$ (even curves only). + * If $g(-u-x)$ is square, return $\bot.$ + * Let $s = -g(u)/(u^2 + ux + x^2 + a)$ (cannot cause division by zero). + * Let $v = x.$ +* Otherwise, when $c \in \\{2, 3\\}:$ + * Let $s = x-u.$ + * Let $r = \sqrt{-s(4g(u) + sh(u))}$; return $\bot$ if not square. + * If $c = 3$ and $r = 0$, return $\bot.$ + * Let $v = (r/s - u)/2.$ +* Let $w = \sqrt{s}$; return $\bot$ if not square. +* Let $w' = w$ if $sign(w/2) = sign(y)$; $-w$ otherwise. +* Depending on $c:$ + * If $c \in \\{0, 2\\}:$ return $P_u^{'-1}(v, w').$ + * If $c \in \\{1, 3\\}:$ return $P_u^{'-1}(-u-v, w').$ + +Note that $c$ now only ranges $[0,4)$, as the sign of $w'$ is decided based on that of $y$, rather than on $c.$ +This change makes some valid encodings unreachable: when $y = 0$ and $sign(Y) \neq sign(0)$. + +In the above logic, $sign$ can be implemented in several ways, such as parity of the integer representation +of the input field element (for prime-sized fields) or the quadratic residuosity (for fields where +$-1$ is not square). The choice does not matter, as long as it only takes on two possible values, and for $x \neq 0$ it holds that $sign(x) \neq sign(-x)$. + +### 4.1 Full *(x, y)* coordinates for `secp256k1` + +For $a=0$ curves, there is another option. Note that for those, +the $P_u(t)$ function translates negations of $t$ to negations of (both) $X$ and $Y.$ Thus, we can use $sign(t)$ to +encode the y-coordinate directly. Combined with the earlier remapping to guarantee all inputs land on the curve, we get +as decoder: + +**Define** *Decode(u, t)* as: +* Let $u'=u$ if $u \neq 0$; $1$ otherwise. +* Let $t'=t$ if $t \neq 0$; $1$ otherwise. +* Let $t''=t'$ if $u'^3 + b + t'^2 \neq 0$; $2t'$ otherwise. +* Let $X = \dfrac{u'^3 + b - t''^2}{2t''}.$ +* Let $Y = \dfrac{X + t''}{u'\sqrt{-3}}.$ +* Let $x$ be the first element of $(u' + 4Y^2, \frac{-X}{2Y} - \frac{u'}{2}, \frac{X}{2Y} - \frac{u'}{2})$ for which $g(x)$ is square. +* Let $y = \sqrt{g(x)}.$ +* Return $(x, y)$ if $sign(y) = sign(t)$; $(x, -y)$ otherwise. + +This is implemented in `secp256k1_ellswift_swiftec_var`. The used $sign(x)$ function is the parity of $x$ when represented as in integer in $[0,q).$ + +The corresponding encoder would invoke the x-only one, but negating the output $t$ if $sign(t) \neq sign(y).$ + +This is implemented in `secp256k1_ellswift_elligatorswift_var`. + +Note that this is only intended for encoding points where both the x-coordinate and y-coordinate are unpredictable.

Computing the Greatest Common Divisor (GCD) using divsteps + +The algorithm from the paper (section 11), at a very high level, is this: + +```python +def gcd(f, g): + """Compute the GCD of an odd integer f and another integer g.""" + assert f & 1 # require f to be odd + delta = 1 # additional state variable + while g != 0: + assert f & 1 # f will be odd in every iteration + if delta > 0 and g & 1: + delta, f, g = 1 - delta, g, (g - f) // 2 + elif g & 1: + delta, f, g = 1 + delta, f, (g + f) // 2 + else: + delta, f, g = 1 + delta, f, (g ) // 2 + return abs(f) +``` + +It computes the greatest common divisor of an odd integer *f* and any integer *g*. Its inner loop +keeps rewriting the variables *f* and *g* alongside a state variable *δ* that starts at *1*, until +*g=0* is reached. At that point, *|f|* gives the GCD. Each of the transitions in the loop is called a +"division step" (referred to as divstep in what follows). + +For example, *gcd(21, 14)* would be computed as: +- Start with *δ=1 f=21 g=14* +- Take the third branch: *δ=2 f=21 g=7* +- Take the first branch: *δ=-1 f=7 g=-7* +- Take the second branch: *δ=0 f=7 g=0* +- The answer *|f| = 7*. + +Why it works: +- Divsteps can be decomposed into two steps (see paragraph 8.2 in the paper): + - (a) If *g* is odd, replace *(f,g)* with *(g,g-f)* or (f,g+f), resulting in an even *g*. + - (b) Replace *(f,g)* with *(f,g/2)* (where *g* is guaranteed to be even). +- Neither of those two operations change the GCD: + - For (a), assume *gcd(f,g)=c*, then it must be the case that *f=a c* and *g=b c* for some integers *a* + and *b*. As *(g,g-f)=(b c,(b-a)c)* and *(f,f+g)=(a c,(a+b)c)*, the result clearly still has + common factor *c*. Reasoning in the other direction shows that no common factor can be added by + doing so either. + - For (b), we know that *f* is odd, so *gcd(f,g)* clearly has no factor *2*, and we can remove + it from *g*. +- The algorithm will eventually converge to *g=0*. This is proven in the paper (see theorem G.3). +- It follows that eventually we find a final value *f'* for which *gcd(f,g) = gcd(f',0)*. As the + gcd of *f'* and *0* is *|f'|* by definition, that is our answer. + +Compared to more [traditional GCD algorithms](https://en.wikipedia.org/wiki/Euclidean_algorithm), this one has the property of only ever looking at +the low-order bits of the variables to decide the next steps, and being easy to make +constant-time (in more low-level languages than Python). The *δ* parameter is necessary to +guide the algorithm towards shrinking the numbers' magnitudes without explicitly needing to look +at high order bits. + +Properties that will become important later: +- Performing more divsteps than needed is not a problem, as *f* does not change anymore after *g=0*. +- Only even numbers are divided by *2*. This means that when reasoning about it algebraically we + do not need to worry about rounding. +- At every point during the algorithm's execution the next *N* steps only depend on the bottom *N* + bits of *f* and *g*, and on *δ*. + + +## 2. From GCDs to modular inverses + +We want an algorithm to compute the inverse *a* of *x* modulo *M*, i.e. the number a such that *a x=1 +mod M*. This inverse only exists if the GCD of *x* and *M* is *1*, but that is always the case if *M* is +prime and *0 < x < M*. In what follows, assume that the modular inverse exists. +It turns out this inverse can be computed as a side effect of computing the GCD by keeping track +of how the internal variables can be written as linear combinations of the inputs at every step +(see the [extended Euclidean algorithm](https://en.wikipedia.org/wiki/Extended_Euclidean_algorithm)). +Since the GCD is *1*, such an algorithm will compute numbers *a* and *b* such that a x + b M = 1*. +Taking that expression *mod M* gives *a x mod M = 1*, and we see that *a* is the modular inverse of *x +mod M*. + +A similar approach can be used to calculate modular inverses using the divsteps-based GCD +algorithm shown above, if the modulus *M* is odd. To do so, compute *gcd(f=M,g=x)*, while keeping +track of extra variables *d* and *e*, for which at every step *d = f/x (mod M)* and *e = g/x (mod M)*. +*f/x* here means the number which multiplied with *x* gives *f mod M*. As *f* and *g* are initialized to *M* +and *x* respectively, *d* and *e* just start off being *0* (*M/x mod M = 0/x mod M = 0*) and *1* (*x/x mod M += 1*). + +```python +def div2(M, x): + """Helper routine to compute x/2 mod M (where M is odd).""" + assert M & 1 + if x & 1: # If x is odd, make it even by adding M. + x += M + # x must be even now, so a clean division by 2 is possible. + return x // 2 + +def modinv(M, x): + """Compute the inverse of x mod M (given that it exists, and M is odd).""" + assert M & 1 + delta, f, g, d, e = 1, M, x, 0, 1 + while g != 0: + # Note that while division by two for f and g is only ever done on even inputs, this is + # not true for d and e, so we need the div2 helper function. + if delta > 0 and g & 1: + delta, f, g, d, e = 1 - delta, g, (g - f) // 2, e, div2(M, e - d) + elif g & 1: + delta, f, g, d, e = 1 + delta, f, (g + f) // 2, d, div2(M, e + d) + else: + delta, f, g, d, e = 1 + delta, f, (g ) // 2, d, div2(M, e ) + # Verify that the invariants d=f/x mod M, e=g/x mod M are maintained. + assert f % M == (d * x) % M + assert g % M == (e * x) % M + assert f == 1 or f == -1 # |f| is the GCD, it must be 1 + # Because of invariant d = f/x (mod M), 1/x = d/f (mod M). As |f|=1, d/f = d*f. + return (d * f) % M +``` + +Also note that this approach to track *d* and *e* throughout the computation to determine the inverse +is different from the paper. There (see paragraph 12.1 in the paper) a transition matrix for the +entire computation is determined (see section 3 below) and the inverse is computed from that. +The approach here avoids the need for 2x2 matrix multiplications of various sizes, and appears to +be faster at the level of optimization we're able to do in C. + + +## 3. Batching multiple divsteps + +Every divstep can be expressed as a matrix multiplication, applying a transition matrix *(1/2 t)* +to both vectors *[f, g]* and *[d, e]* (see paragraph 8.1 in the paper): + +``` + t = [ u, v ] + [ q, r ] + + [ out_f ] = (1/2 * t) * [ in_f ] + [ out_g ] = [ in_g ] + + [ out_d ] = (1/2 * t) * [ in_d ] (mod M) + [ out_e ] [ in_e ] +``` + +where *(u, v, q, r)* is *(0, 2, -1, 1)*, *(2, 0, 1, 1)*, or *(2, 0, 0, 1)*, depending on which branch is +taken. As above, the resulting *f* and *g* are always integers. + +Performing multiple divsteps corresponds to a multiplication with the product of all the +individual divsteps' transition matrices. As each transition matrix consists of integers +divided by *2*, the product of these matrices will consist of integers divided by *2N* (see also +theorem 9.2 in the paper). These divisions are expensive when updating *d* and *e*, so we delay +them: we compute the integer coefficients of the combined transition matrix scaled by *2N*, and +do one division by *2N* as a final step: + +```python +def divsteps_n_matrix(delta, f, g): + """Compute delta and transition matrix t after N divsteps (multiplied by 2^N).""" + u, v, q, r = 1, 0, 0, 1 # start with identity matrix + for _ in range(N): + if delta > 0 and g & 1: + delta, f, g, u, v, q, r = 1 - delta, g, (g - f) // 2, 2*q, 2*r, q-u, r-v + elif g & 1: + delta, f, g, u, v, q, r = 1 + delta, f, (g + f) // 2, 2*u, 2*v, q+u, r+v + else: + delta, f, g, u, v, q, r = 1 + delta, f, (g ) // 2, 2*u, 2*v, q , r + return delta, (u, v, q, r) +``` + +As the branches in the divsteps are completely determined by the bottom *N* bits of *f* and *g*, this +function to compute the transition matrix only needs to see those bottom bits. Furthermore all +intermediate results and outputs fit in *(N+1)*-bit numbers (unsigned for *f* and *g*; signed for *u*, *v*, +*q*, and *r*) (see also paragraph 8.3 in the paper). This means that an implementation using 64-bit +integers could set *N=62* and compute the full transition matrix for 62 steps at once without any +big integer arithmetic at all. This is the reason why this algorithm is efficient: it only needs +to update the full-size *f*, *g*, *d*, and *e* numbers once every *N* steps. + +We still need functions to compute: + +``` + [ out_f ] = (1/2^N * [ u, v ]) * [ in_f ] + [ out_g ] ( [ q, r ]) [ in_g ] + + [ out_d ] = (1/2^N * [ u, v ]) * [ in_d ] (mod M) + [ out_e ] ( [ q, r ]) [ in_e ] +``` + +Because the divsteps transformation only ever divides even numbers by two, the result of *t [f,g]* is always even. When *t* is a composition of *N* divsteps, it follows that the resulting *f* +and *g* will be multiple of *2N*, and division by *2N* is simply shifting them down: + +```python +def update_fg(f, g, t): + """Multiply matrix t/2^N with [f, g].""" + u, v, q, r = t + cf, cg = u*f + v*g, q*f + r*g + # (t / 2^N) should cleanly apply to [f,g] so the result of t*[f,g] should have N zero + # bottom bits. + assert cf % 2**N == 0 + assert cg % 2**N == 0 + return cf >> N, cg >> N +``` + +The same is not true for *d* and *e*, and we need an equivalent of the `div2` function for division by *2N mod M*. +This is easy if we have precomputed *1/M mod 2N* (which always exists for odd *M*): + +```python +def div2n(M, Mi, x): + """Compute x/2^N mod M, given Mi = 1/M mod 2^N.""" + assert (M * Mi) % 2**N == 1 + # Find a factor m such that m*M has the same bottom N bits as x. We want: + # (m * M) mod 2^N = x mod 2^N + # <=> m mod 2^N = (x / M) mod 2^N + # <=> m mod 2^N = (x * Mi) mod 2^N + m = (Mi * x) % 2**N + # Subtract that multiple from x, cancelling its bottom N bits. + x -= m * M + # Now a clean division by 2^N is possible. + assert x % 2**N == 0 + return (x >> N) % M + +def update_de(d, e, t, M, Mi): + """Multiply matrix t/2^N with [d, e], modulo M.""" + u, v, q, r = t + cd, ce = u*d + v*e, q*d + r*e + return div2n(M, Mi, cd), div2n(M, Mi, ce) +``` + +With all of those, we can write a version of `modinv` that performs *N* divsteps at once: + +```python3 +def modinv(M, Mi, x): + """Compute the modular inverse of x mod M, given Mi=1/M mod 2^N.""" + assert M & 1 + delta, f, g, d, e = 1, M, x, 0, 1 + while g != 0: + # Compute the delta and transition matrix t for the next N divsteps (this only needs + # (N+1)-bit signed integer arithmetic). + delta, t = divsteps_n_matrix(delta, f % 2**N, g % 2**N) + # Apply the transition matrix t to [f, g]: + f, g = update_fg(f, g, t) + # Apply the transition matrix t to [d, e]: + d, e = update_de(d, e, t, M, Mi) + return (d * f) % M +``` + +This means that in practice we'll always perform a multiple of *N* divsteps. This is not a problem +because once *g=0*, further divsteps do not affect *f*, *g*, *d*, or *e* anymore (only *δ* keeps +increasing). For variable time code such excess iterations will be mostly optimized away in later +sections. + + +## 4. Avoiding modulus operations + +So far, there are two places where we compute a remainder of big numbers modulo *M*: at the end of +`div2n` in every `update_de`, and at the very end of `modinv` after potentially negating *d* due to the +sign of *f*. These are relatively expensive operations when done generically. + +To deal with the modulus operation in `div2n`, we simply stop requiring *d* and *e* to be in range +*[0,M)* all the time. Let's start by inlining `div2n` into `update_de`, and dropping the modulus +operation at the end: + +```python +def update_de(d, e, t, M, Mi): + """Multiply matrix t/2^N with [d, e] mod M, given Mi=1/M mod 2^N.""" + u, v, q, r = t + cd, ce = u*d + v*e, q*d + r*e + # Cancel out bottom N bits of cd and ce. + md = -((Mi * cd) % 2**N) + me = -((Mi * ce) % 2**N) + cd += md * M + ce += me * M + # And cleanly divide by 2**N. + return cd >> N, ce >> N +``` + +Let's look at bounds on the ranges of these numbers. It can be shown that *|u|+|v|* and *|q|+|r|* +never exceed *2N* (see paragraph 8.3 in the paper), and thus a multiplication with *t* will have +outputs whose absolute values are at most *2N* times the maximum absolute input value. In case the +inputs *d* and *e* are in *(-M,M)*, which is certainly true for the initial values *d=0* and *e=1* assuming +*M > 1*, the multiplication results in numbers in range *(-2NM,2NM)*. Subtracting less than *2N* +times *M* to cancel out *N* bits brings that up to *(-2N+1M,2NM)*, and +dividing by *2N* at the end takes it to *(-2M,M)*. Another application of `update_de` would take that +to *(-3M,2M)*, and so forth. This progressive expansion of the variables' ranges can be +counteracted by incrementing *d* and *e* by *M* whenever they're negative: + +```python + ... + if d < 0: + d += M + if e < 0: + e += M + cd, ce = u*d + v*e, q*d + r*e + # Cancel out bottom N bits of cd and ce. + ... +``` + +With inputs in *(-2M,M)*, they will first be shifted into range *(-M,M)*, which means that the +output will again be in *(-2M,M)*, and this remains the case regardless of how many `update_de` +invocations there are. In what follows, we will try to make this more efficient. + +Note that increasing *d* by *M* is equal to incrementing *cd* by *u M* and *ce* by *q M*. Similarly, +increasing *e* by *M* is equal to incrementing *cd* by *v M* and *ce* by *r M*. So we could instead write: + +```python + ... + cd, ce = u*d + v*e, q*d + r*e + # Perform the equivalent of incrementing d, e by M when they're negative. + if d < 0: + cd += u*M + ce += q*M + if e < 0: + cd += v*M + ce += r*M + # Cancel out bottom N bits of cd and ce. + md = -((Mi * cd) % 2**N) + me = -((Mi * ce) % 2**N) + cd += md * M + ce += me * M + ... +``` + +Now note that we have two steps of corrections to *cd* and *ce* that add multiples of *M*: this +increment, and the decrement that cancels out bottom bits. The second one depends on the first +one, but they can still be efficiently combined by only computing the bottom bits of *cd* and *ce* +at first, and using that to compute the final *md*, *me* values: + +```python +def update_de(d, e, t, M, Mi): + """Multiply matrix t/2^N with [d, e], modulo M.""" + u, v, q, r = t + md, me = 0, 0 + # Compute what multiples of M to add to cd and ce. + if d < 0: + md += u + me += q + if e < 0: + md += v + me += r + # Compute bottom N bits of t*[d,e] + M*[md,me]. + cd, ce = (u*d + v*e + md*M) % 2**N, (q*d + r*e + me*M) % 2**N + # Correct md and me such that the bottom N bits of t*[d,e] + M*[md,me] are zero. + md -= (Mi * cd) % 2**N + me -= (Mi * ce) % 2**N + # Do the full computation. + cd, ce = u*d + v*e + md*M, q*d + r*e + me*M + # And cleanly divide by 2**N. + return cd >> N, ce >> N +``` + +One last optimization: we can avoid the *md M* and *me M* multiplications in the bottom bits of *cd* +and *ce* by moving them to the *md* and *me* correction: + +```python + ... + # Compute bottom N bits of t*[d,e]. + cd, ce = (u*d + v*e) % 2**N, (q*d + r*e) % 2**N + # Correct md and me such that the bottom N bits of t*[d,e]+M*[md,me] are zero. + # Note that this is not the same as {md = (-Mi * cd) % 2**N} etc. That would also result in N + # zero bottom bits, but isn't guaranteed to be a reduction of [0,2^N) compared to the + # previous md and me values, and thus would violate our bounds analysis. + md -= (Mi*cd + md) % 2**N + me -= (Mi*ce + me) % 2**N + ... +``` + +The resulting function takes *d* and *e* in range *(-2M,M)* as inputs, and outputs values in the same +range. That also means that the *d* value at the end of `modinv` will be in that range, while we want +a result in *[0,M)*. To do that, we need a normalization function. It's easy to integrate the +conditional negation of *d* (based on the sign of *f*) into it as well: + +```python +def normalize(sign, v, M): + """Compute sign*v mod M, where v is in range (-2*M,M); output in [0,M).""" + assert sign == 1 or sign == -1 + # v in (-2*M,M) + if v < 0: + v += M + # v in (-M,M). Now multiply v with sign (which can only be 1 or -1). + if sign == -1: + v = -v + # v in (-M,M) + if v < 0: + v += M + # v in [0,M) + return v +``` + +And calling it in `modinv` is simply: + +```python + ... + return normalize(f, d, M) +``` + + +## 5. Constant-time operation + +The primary selling point of the algorithm is fast constant-time operation. What code flow still +depends on the input data so far? + +- the number of iterations of the while *g ≠ 0* loop in `modinv` +- the branches inside `divsteps_n_matrix` +- the sign checks in `update_de` +- the sign checks in `normalize` + +To make the while loop in `modinv` constant time it can be replaced with a constant number of +iterations. The paper proves (Theorem 11.2) that *741* divsteps are sufficient for any *256*-bit +inputs, and [safegcd-bounds](https://github.com/sipa/safegcd-bounds) shows that the slightly better bound *724* is +sufficient even. Given that every loop iteration performs *N* divsteps, it will run a total of +*⌈724/N⌉* times. + +To deal with the branches in `divsteps_n_matrix` we will replace them with constant-time bitwise +operations (and hope the C compiler isn't smart enough to turn them back into branches; see +`ctime_tests.c` for automated tests that this isn't the case). To do so, observe that a +divstep can be written instead as (compare to the inner loop of `gcd` in section 1). + +```python + x = -f if delta > 0 else f # set x equal to (input) -f or f + if g & 1: + g += x # set g to (input) g-f or g+f + if delta > 0: + delta = -delta + f += g # set f to (input) g (note that g was set to g-f before) + delta += 1 + g >>= 1 +``` + +To convert the above to bitwise operations, we rely on a trick to negate conditionally: per the +definition of negative numbers in two's complement, (*-v == ~v + 1*) holds for every number *v*. As +*-1* in two's complement is all *1* bits, bitflipping can be expressed as xor with *-1*. It follows +that *-v == (v ^ -1) - (-1)*. Thus, if we have a variable *c* that takes on values *0* or *-1*, then +*(v ^ c) - c* is *v* if *c=0* and *-v* if *c=-1*. + +Using this we can write: + +```python + x = -f if delta > 0 else f +``` + +in constant-time form as: + +```python + c1 = (-delta) >> 63 + # Conditionally negate f based on c1: + x = (f ^ c1) - c1 +``` + +To use that trick, we need a helper mask variable *c1* that resolves the condition *δ>0* to *-1* +(if true) or *0* (if false). We compute *c1* using right shifting, which is equivalent to dividing by +the specified power of *2* and rounding down (in Python, and also in C under the assumption of a typical two's complement system; see +`assumptions.h` for tests that this is the case). Right shifting by *63* thus maps all +numbers in range *[-263,0)* to *-1*, and numbers in range *[0,263)* to *0*. + +Using the facts that *x&0=0* and *x&(-1)=x* (on two's complement systems again), we can write: + +```python + if g & 1: + g += x +``` + +as: + +```python + # Compute c2=0 if g is even and c2=-1 if g is odd. + c2 = -(g & 1) + # This masks out x if g is even, and leaves x be if g is odd. + g += x & c2 +``` + +Using the conditional negation trick again we can write: + +```python + if g & 1: + if delta > 0: + delta = -delta +``` + +as: + +```python + # Compute c3=-1 if g is odd and delta>0, and 0 otherwise. + c3 = c1 & c2 + # Conditionally negate delta based on c3: + delta = (delta ^ c3) - c3 +``` + +Finally: + +```python + if g & 1: + if delta > 0: + f += g +``` + +becomes: + +```python + f += g & c3 +``` + +It turns out that this can be implemented more efficiently by applying the substitution +*η=-δ*. In this representation, negating *δ* corresponds to negating *η*, and incrementing +*δ* corresponds to decrementing *η*. This allows us to remove the negation in the *c1* +computation: + +```python + # Compute a mask c1 for eta < 0, and compute the conditional negation x of f: + c1 = eta >> 63 + x = (f ^ c1) - c1 + # Compute a mask c2 for odd g, and conditionally add x to g: + c2 = -(g & 1) + g += x & c2 + # Compute a mask c for (eta < 0) and odd (input) g, and use it to conditionally negate eta, + # and add g to f: + c3 = c1 & c2 + eta = (eta ^ c3) - c3 + f += g & c3 + # Incrementing delta corresponds to decrementing eta. + eta -= 1 + g >>= 1 +``` + +A variant of divsteps with better worst-case performance can be used instead: starting *δ* at +*1/2* instead of *1*. This reduces the worst case number of iterations to *590* for *256*-bit inputs +(which can be shown using convex hull analysis). In this case, the substitution *ζ=-(δ+1/2)* +is used instead to keep the variable integral. Incrementing *δ* by *1* still translates to +decrementing *ζ* by *1*, but negating *δ* now corresponds to going from *ζ* to *-(ζ+1)*, or +*~ζ*. Doing that conditionally based on *c3* is simply: + +```python + ... + c3 = c1 & c2 + zeta ^= c3 + ... +``` + +By replacing the loop in `divsteps_n_matrix` with a variant of the divstep code above (extended to +also apply all *f* operations to *u*, *v* and all *g* operations to *q*, *r*), a constant-time version of +`divsteps_n_matrix` is obtained. The full code will be in section 7. + +These bit fiddling tricks can also be used to make the conditional negations and additions in +`update_de` and `normalize` constant-time. + + +## 6. Variable-time optimizations + +In section 5, we modified the `divsteps_n_matrix` function (and a few others) to be constant time. +Constant time operations are only necessary when computing modular inverses of secret data. In +other cases, it slows down calculations unnecessarily. In this section, we will construct a +faster non-constant time `divsteps_n_matrix` function. + +To do so, first consider yet another way of writing the inner loop of divstep operations in +`gcd` from section 1. This decomposition is also explained in the paper in section 8.2. We use +the original version with initial *δ=1* and *η=-δ* here. + +```python +for _ in range(N): + if g & 1 and eta < 0: + eta, f, g = -eta, g, -f + if g & 1: + g += f + eta -= 1 + g >>= 1 +``` + +Whenever *g* is even, the loop only shifts *g* down and decreases *η*. When *g* ends in multiple zero +bits, these iterations can be consolidated into one step. This requires counting the bottom zero +bits efficiently, which is possible on most platforms; it is abstracted here as the function +`count_trailing_zeros`. + +```python +def count_trailing_zeros(v): + """ + When v is zero, consider all N zero bits as "trailing". + For a non-zero value v, find z such that v=(d<>= zeros + i -= zeros + if i == 0: + break + # We know g is odd now + if eta < 0: + eta, f, g = -eta, g, -f + g += f + # g is even now, and the eta decrement and g shift will happen in the next loop. +``` + +We can now remove multiple bottom *0* bits from *g* at once, but still need a full iteration whenever +there is a bottom *1* bit. In what follows, we will get rid of multiple *1* bits simultaneously as +well. + +Observe that as long as *η ≥ 0*, the loop does not modify *f*. Instead, it cancels out bottom +bits of *g* and shifts them out, and decreases *η* and *i* accordingly - interrupting only when *η* +becomes negative, or when *i* reaches *0*. Combined, this is equivalent to adding a multiple of *f* to +*g* to cancel out multiple bottom bits, and then shifting them out. + +It is easy to find what that multiple is: we want a number *w* such that *g+w f* has a few bottom +zero bits. If that number of bits is *L*, we want *g+w f mod 2L = 0*, or *w = -g/f mod 2L*. Since *f* +is odd, such a *w* exists for any *L*. *L* cannot be more than *i* steps (as we'd finish the loop before +doing more) or more than *η+1* steps (as we'd run `eta, f, g = -eta, g, -f` at that point), but +apart from that, we're only limited by the complexity of computing *w*. + +This code demonstrates how to cancel up to 4 bits per step: + +```python +NEGINV16 = [15, 5, 3, 9, 7, 13, 11, 1] # NEGINV16[n//2] = (-n)^-1 mod 16, for odd n +i = N +while True: + zeros = min(i, count_trailing_zeros(g)) + eta -= zeros + g >>= zeros + i -= zeros + if i == 0: + break + # We know g is odd now + if eta < 0: + eta, f, g = -eta, g, -f + # Compute limit on number of bits to cancel + limit = min(min(eta + 1, i), 4) + # Compute w = -g/f mod 2**limit, using the table value for -1/f mod 2**4. Note that f is + # always odd, so its inverse modulo a power of two always exists. + w = (g * NEGINV16[(f & 15) // 2]) % (2**limit) + # As w = -g/f mod (2**limit), g+w*f mod 2**limit = 0 mod 2**limit. + g += w * f + assert g % (2**limit) == 0 + # The next iteration will now shift out at least limit bottom zero bits from g. +``` + +By using a bigger table more bits can be cancelled at once. The table can also be implemented +as a formula. Several formulas are known for computing modular inverses modulo powers of two; +some can be found in Hacker's Delight second edition by Henry S. Warren, Jr. pages 245-247. +Here we need the negated modular inverse, which is a simple transformation of those: + +- Instead of a 3-bit table: + - *-f* or *f ^ 6* +- Instead of a 4-bit table: + - *1 - f(f + 1)* + - *-(f + (((f + 1) & 4) << 1))* +- For larger tables the following technique can be used: if *w=-1/f mod 2L*, then *w(w f+2)* is + *-1/f mod 22L*. This allows extending the previous formulas (or tables). In particular we + have this 6-bit function (based on the 3-bit function above): + - *f(f2 - 2)* + +This loop, again extended to also handle *u*, *v*, *q*, and *r* alongside *f* and *g*, placed in +`divsteps_n_matrix`, gives a significantly faster, but non-constant time version. + + +## 7. Final Python version + +All together we need the following functions: + +- A way to compute the transition matrix in constant time, using the `divsteps_n_matrix` function + from section 2, but with its loop replaced by a variant of the constant-time divstep from + section 5, extended to handle *u*, *v*, *q*, *r*: + +```python +def divsteps_n_matrix(zeta, f, g): + """Compute zeta and transition matrix t after N divsteps (multiplied by 2^N).""" + u, v, q, r = 1, 0, 0, 1 # start with identity matrix + for _ in range(N): + c1 = zeta >> 63 + # Compute x, y, z as conditionally-negated versions of f, u, v. + x, y, z = (f ^ c1) - c1, (u ^ c1) - c1, (v ^ c1) - c1 + c2 = -(g & 1) + # Conditionally add x, y, z to g, q, r. + g, q, r = g + (x & c2), q + (y & c2), r + (z & c2) + c1 &= c2 # reusing c1 here for the earlier c3 variable + zeta = (zeta ^ c1) - 1 # inlining the unconditional zeta decrement here + # Conditionally add g, q, r to f, u, v. + f, u, v = f + (g & c1), u + (q & c1), v + (r & c1) + # When shifting g down, don't shift q, r, as we construct a transition matrix multiplied + # by 2^N.

From GCDs to Jacobi symbol + +We can also use a similar approach to calculate Jacobi symbol *(x | M)* by keeping track of an +extra variable *j*, for which at every step *(x | M) = j (g | f)*. As we update *f* and *g*, we +make corresponding updates to *j* using +[properties of the Jacobi symbol](https://en.wikipedia.org/wiki/Jacobi_symbol#Properties): +* *((g/2) | f)* is either *(g | f)* or *-(g | f)*, depending on the value of *f mod 8* (negating if it's *3* or *5*). +* *(f | g)* is either *(g | f)* or *-(g | f)*, depending on *f mod 4* and *g mod 4* (negating if both are *3*). + +These updates depend only on the values of *f* and *g* modulo *4* or *8*, and can thus be applied +very quickly, as long as we keep track of a few additional bits of *f* and *g*. Overall, this +calculation is slightly simpler than the one for the modular inverse because we no longer need to +keep track of *d* and *e*. + +However, one difficulty of this approach is that the Jacobi symbol *(a | n)* is only defined for +positive odd integers *n*, whereas in the original safegcd algorithm, *f, g* can take negative +values. We resolve this by using the following modified steps: + +```python + # Before + if delta > 0 and g & 1: + delta, f, g = 1 - delta, g, (g - f) // 2 + + # After + if delta > 0 and g & 1: + delta, f, g = 1 - delta, g, (g + f) // 2 +``` + +The algorithm is still correct, since the changed divstep, called a "posdivstep" (see section 8.4 +and E.5 in the paper) preserves *gcd(f, g)*. However, there's no proof that the modified algorithm +will converge. The justification for posdivsteps is completely empirical: in practice, it appears +that the vast majority of nonzero inputs converge to *f=g=gcd(f0, g0)* in a +number of steps proportional to their logarithm. + +Note that: +- We require inputs to satisfy *gcd(x, M) = 1*, as otherwise *f=1* is not reached. +- We require inputs *x &neq; 0*, because applying posdivstep with *g=0* has no effect. +- We need to update the termination condition from *g=0* to *f=1*. + +We account for the possibility of nonconvergence by only performing a bounded number of +posdivsteps, and then falling back to square-root based Jacobi calculation if a solution has not +yet been found. + +The optimizations in sections 3-7 above are described in the context of the original divsteps, but +in the C implementation we also adapt most of them (not including "avoiding modulus operations", +since it's not necessary to track *d, e*, and "constant-time operation", since we never calculate +Jacobi symbols for secret data) to the posdivsteps version. diff --git a/crypto/secp256k1/libsecp256k1/examples/CMakeLists.txt b/crypto/secp256k1/libsecp256k1/examples/CMakeLists.txt new file mode 100644 index 00000000000..c9da9de6be3 --- /dev/null +++ b/crypto/secp256k1/libsecp256k1/examples/CMakeLists.txt @@ -0,0 +1,31 @@ +function(add_example name) + set(target_name ${name}_example) + add_executable(${target_name} ${name}.c) + target_include_directories(${target_name} PRIVATE + ${PROJECT_SOURCE_DIR}/include + ) + target_link_libraries(${target_name} + secp256k1 + $<$:bcrypt> + ) + set(test_name ${name}_example) + add_test(NAME secp256k1_${test_name} COMMAND ${target_name}) +endfunction() + +add_example(ecdsa) + +if(SECP256K1_ENABLE_MODULE_ECDH) + add_example(ecdh) +endif() + +if(SECP256K1_ENABLE_MODULE_SCHNORRSIG) + add_example(schnorr) +endif() + +if(SECP256K1_ENABLE_MODULE_ELLSWIFT) + add_example(ellswift) +endif() + +if(SECP256K1_ENABLE_MODULE_MUSIG) + add_example(musig) +endif() diff --git a/crypto/secp256k1/libsecp256k1/examples/EXAMPLES_COPYING b/crypto/secp256k1/libsecp256k1/examples/EXAMPLES_COPYING new file mode 100644 index 00000000000..0e259d42c99 --- /dev/null +++ b/crypto/secp256k1/libsecp256k1/examples/EXAMPLES_COPYING @@ -0,0 +1,121 @@ +Creative Commons Legal Code + +CC0 1.0 Universal + + CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE + LEGAL SERVICES.

This new curve has the same order as + * the original (it is isomorphic), but moreover, has the same addition/doubling formulas, as + * the curve b=7 coefficient does not appear in those formulas (or at least does not appear in + * the formulas implemented in this codebase, both affine and Jacobian). See also Example 9.5.2 + * in https://www.math.auckland.ac.nz/~sgal018/crypto-book/ch9.pdf. + * + * This means any linear combination of secp256k1 points can be computed by applying phi_u + * (with non-zero u) on all input points (including the generator, if used), computing the + * linear combination on the isomorphic curve (using the same group laws), and then applying + * phi_u^{-1} to get back to secp256k1. + * + * Switching to Jacobian coordinates, note that phi_u applied to (X, Y, Z) is simply + * (X, Y, Z/u). Thus, if we want to compute (X1, Y1, Z) + (X2, Y2, Z), with identical Z + * coordinates, we can use phi_Z to transform it to (X1, Y1, 1) + (X2, Y2, 1) on an isomorphic + * curve where the affine addition formula can be used instead. + * If (X3, Y3, Z3) = (X1, Y1) + (X2, Y2) on that curve, then our answer on secp256k1 is + * (X3, Y3, Z3*Z). + * + * This is the effective affine technique: if we have a linear combination of group elements + * to compute, and all those group elements have the same Z coordinate, we can simply pretend + * that all those Z coordinates are 1, perform the computation that way, and then multiply the + * original Z coordinate back in. + * + * The technique works on any a=0 short Weierstrass curve. It is possible to generalize it to + * other curves too, but there the isomorphic curves will have different 'a' coefficients, + * which typically does affect the group laws. + * + * + * === Avoiding the square root for x-only point multiplication === + * + * In this function, we want to compute the X coordinate of q*(n/d, y), for + * y = sqrt((n/d)^3 + 7). Its negation would also be a valid Y coordinate, but by convention + * we pick whatever sqrt returns (which we assume to be a deterministic function). + * + * Let g = y^2*d^3 = n^3 + 7*d^3. This also means y = sqrt(g/d^3). + * Further let v = sqrt(d*g), which must exist as d*g = y^2*d^4 = (y*d^2)^2. + * + * The input point (n/d, y) also has Jacobian coordinates: + * + * (n/d, y, 1) + * = (n/d * v^2, y * v^3, v) + * = (n/d * d*g, y * sqrt(d^3*g^3), v) + * = (n/d * d*g, sqrt(y^2 * d^3*g^3), v) + * = (n*g, sqrt(g/d^3 * d^3*g^3), v) + * = (n*g, sqrt(g^4), v) + * = (n*g, g^2, v) + * + * It is easy to verify that both (n*g, g^2, v) and its negation (n*g, -g^2, v) have affine X + * coordinate n/d, and this holds even when the square root function doesn't have a + * deterministic sign. We choose the (n*g, g^2, v) version. + * + * Now switch to the effective affine curve using phi_v, where the input point has coordinates + * (n*g, g^2). Compute (X, Y, Z) = q * (n*g, g^2) there. + * + * Back on secp256k1, that means q * (n*g, g^2, v) = (X, Y, v*Z). This last point has affine X + * coordinate X / (v^2*Z^2) = X / (d*g*Z^2). Determining the affine Y coordinate would involve + * a square root, but as long as we only care about the resulting X coordinate, no square root + * is needed anywhere in this computation. + */ - /* Apply the correction */ - secp256k1_ge_from_storage(&correction, &correction_1_stor); - secp256k1_ge_neg(&correction, &correction); - secp256k1_gej_add_ge(r, r, &correction); + secp256k1_fe g, i; + secp256k1_ge p; + secp256k1_gej rj; -#ifdef USE_ENDOMORPHISM - secp256k1_ge_from_storage(&correction, &correction_lam_stor); - secp256k1_ge_neg(&correction, &correction); - secp256k1_ge_mul_lambda(&correction, &correction); - secp256k1_gej_add_ge(r, r, &correction); -#endif + /* Compute g = (n^3 + B*d^3). */ + secp256k1_fe_sqr(&g, n); + secp256k1_fe_mul(&g, &g, n); + if (d) { + secp256k1_fe b; + VERIFY_CHECK(!secp256k1_fe_normalizes_to_zero(d)); + secp256k1_fe_sqr(&b, d); + VERIFY_CHECK(SECP256K1_B <= 8); /* magnitude of b will be <= 8 after the next call */ + secp256k1_fe_mul_int(&b, SECP256K1_B); + secp256k1_fe_mul(&b, &b, d); + secp256k1_fe_add(&g, &b); + if (!known_on_curve) { + /* We need to determine whether (n/d)^3 + 7 is square. + * + * is_square((n/d)^3 + 7) + * <=> is_square(((n/d)^3 + 7) * d^4) + * <=> is_square((n^3 + 7*d^3) * d) + * <=> is_square(g * d) + */ + secp256k1_fe c; + secp256k1_fe_mul(&c, &g, d); + if (!secp256k1_fe_is_square_var(&c)) return 0; + } + } else { + secp256k1_fe_add_int(&g, SECP256K1_B); + if (!known_on_curve) { + /* g at this point equals x^3 + 7.

This can not be exposed as a wrapper through the `OverrideEVMResetArgs` because `SetTxContext` is called _prior_ to resetting the EVM instance. Therefore, the `SetTxContext` function on any DB wrapper would never be called. ## How this works Exposes the existing `txHash` through a `TxHash()` function. ## How this was tested Added a trivial unit test. --- core/state/statedb.libevm.go | 5 +++++ core/state/statedb.libevm_test.go | 12 ++++++++++++ 2 files changed, 17 insertions(+) diff --git a/core/state/statedb.libevm.go b/core/state/statedb.libevm.go index 7db3d676e97..df758f01d61 100644 --- a/core/state/statedb.libevm.go +++ b/core/state/statedb.libevm.go @@ -24,6 +24,11 @@ import ( "github.com/ava-labs/libevm/libevm/stateconf" ) +// TxHash returns the current transaction hash set by [StateDB.SetTxContext]. +func (s *StateDB) TxHash() common.Hash { + return s.thash +} + // SnapshotTree mirrors the functionality of a [snapshot.Tree], allowing for // drop-in replacements.

This change allows such behaviour to be achieved with pure `libevm` instead of the `StateDB` wrapping that `coreth` currently uses. ## How this works Introduction of `state.StateDBHooks` interface, including a `TransformStateKey()` method that allows for arbitrary change of state key. If registered, this hook will be honoured by `StateDB.{Get,GetCommitted,State}Key()` methods unless they receive a `stateconf.SkipStateKeyTransformation` option. ## How this was tested Unit test of `SetState() -> GetState() + GetCommittedState()` round trip with and without options to skip. --- core/state/statedb.go | 13 ++++-- core/state/statedb.libevm.go | 44 +++++++++++++++++ core/state/statedb.libevm_test.go | 78 +++++++++++++++++++++++++++++++ core/vm/interface.go | 9 ++-- eth/tracers/logger/logger_test.go | 12 +++-- libevm/libevm.go | 5 +- libevm/stateconf/conf.go | 24 ++++++++++ 7 files changed, 173 insertions(+), 12 deletions(-) diff --git a/core/state/statedb.go b/core/state/statedb.go index 68e4b5b2226..487560dab21 100644 --- a/core/state/statedb.go +++ b/core/state/statedb.go @@ -28,7 +28,6 @@ import ( "github.com/ava-labs/libevm/core/state/snapshot" "github.com/ava-labs/libevm/core/types" "github.com/ava-labs/libevm/crypto" - "github.com/ava-labs/libevm/libevm/stateconf" "github.com/ava-labs/libevm/log" "github.com/ava-labs/libevm/metrics" "github.com/ava-labs/libevm/params" @@ -36,6 +35,9 @@ import ( "github.com/ava-labs/libevm/trie/trienode" "github.com/ava-labs/libevm/trie/triestate" "github.com/holiman/uint256" + + // libevm extra imports + "github.com/ava-labs/libevm/libevm/stateconf" ) const ( @@ -341,18 +343,20 @@ func (s *StateDB) GetCodeHash(addr common.Address) common.Hash { } // GetState retrieves a value from the given account's storage trie. -func (s *StateDB) GetState(addr common.Address, hash common.Hash) common.Hash { +func (s *StateDB) GetState(addr common.Address, hash common.Hash, opts ...stateconf.StateDBStateOption) common.Hash { stateObject := s.getStateObject(addr) if stateObject != nil { + hash = transformStateKey(addr, hash, opts...) return stateObject.GetState(hash) } return common.Hash{} } // GetCommittedState retrieves a value from the given account's committed storage trie. -func (s *StateDB) GetCommittedState(addr common.Address, hash common.Hash) common.Hash { +func (s *StateDB) GetCommittedState(addr common.Address, hash common.Hash, opts ...stateconf.StateDBStateOption) common.Hash { stateObject := s.getStateObject(addr) if stateObject != nil { + hash = transformStateKey(addr, hash, opts...) return stateObject.GetCommittedState(hash) } return common.Hash{} @@ -412,9 +416,10 @@ func (s *StateDB) SetCode(addr common.Address, code []byte) { } } -func (s *StateDB) SetState(addr common.Address, key, value common.Hash) { +func (s *StateDB) SetState(addr common.Address, key, value common.Hash, opts ...stateconf.StateDBStateOption) { stateObject := s.getOrNewStateObject(addr) if stateObject != nil { + key = transformStateKey(addr, key, opts...) stateObject.SetState(key, value) } } diff --git a/core/state/statedb.libevm.go b/core/state/statedb.libevm.go index df758f01d61..57346c736d9 100644 --- a/core/state/statedb.libevm.go +++ b/core/state/statedb.libevm.go @@ -21,6 +21,7 @@ import ( "github.com/ava-labs/libevm/common" "github.com/ava-labs/libevm/core/state/snapshot" + "github.com/ava-labs/libevm/libevm/register" "github.com/ava-labs/libevm/libevm/stateconf" ) @@ -57,3 +58,46 @@ func clearTypedNilPointer(snaps SnapshotTree) SnapshotTree { } return snaps } + +// StateDBHooks modify the behaviour of [StateDB] instances. +type StateDBHooks interface { + // TransformStateKey receives the arguments passed to [StateDB.GetState], + // [StateDB.GetCommittedState] or [StateDB.SetState], and returns the key + // that each of those methods will use for accessing state.

The raw versions are the unmodified caller and self. ## How this was tested Extension of existing UTs to include raw addresses in addition to existing, EVM-semantic ones. --- core/vm/contracts.libevm.go | 8 +- core/vm/contracts.libevm_test.go | 146 +++++++++++++++++++------------ core/vm/environment.libevm.go | 12 ++- core/vm/evm.libevm.go | 14 ++- libevm/libevm.go | 28 +++++- params/hooks.libevm.go | 3 +- 6 files changed, 144 insertions(+), 67 deletions(-) diff --git a/core/vm/contracts.libevm.go b/core/vm/contracts.libevm.go index 7d06638ae99..d56dbd1c396 100644 --- a/core/vm/contracts.libevm.go +++ b/core/vm/contracts.libevm.go @@ -223,9 +223,11 @@ func (args *evmCallArgs) env() *environment { } return &environment{ - evm: args.evm, - self: contract, - callType: args.callType, + evm: args.evm, + self: contract, + callType: args.callType, + rawCaller: args.caller.Address(), + rawSelf: args.addr, } } diff --git a/core/vm/contracts.libevm_test.go b/core/vm/contracts.libevm_test.go index 6f9eec3b0a7..525528fb414 100644 --- a/core/vm/contracts.libevm_test.go +++ b/core/vm/contracts.libevm_test.go @@ -120,6 +120,7 @@ type statefulPrecompileOutput struct { func (o statefulPrecompileOutput) String() string { var lines []string out := reflect.ValueOf(o) +FieldLoop: for i, n := 0, out.NumField();

This PR fixes this bug by adding an option to skip freezer inspection. This PR should be followed with a downstream PR in Coreth to pass in an option to skip freezer inspection during database inspection. ## How this works Extends `inspectDatabaseConfig` with a `skipFreezers` field and adds the associated option function for it. ## How this was tested CI + ran `InspectDatabase()` against Coreth locally --- core/rawdb/ancient_utils.go | 6 +++++- core/rawdb/database.go | 2 +- core/rawdb/database.libevm.go | 8 ++++++++ core/rawdb/database.libevm_test.go | 15 +++++++++++++++ 4 files changed, 29 insertions(+), 2 deletions(-) diff --git a/core/rawdb/ancient_utils.go b/core/rawdb/ancient_utils.go index 0b15234690a..1a53993acb9 100644 --- a/core/rawdb/ancient_utils.go +++ b/core/rawdb/ancient_utils.go @@ -22,6 +22,7 @@ import ( "github.com/ava-labs/libevm/common" "github.com/ava-labs/libevm/ethdb" + "github.com/ava-labs/libevm/libevm/options" ) type tableSize struct { @@ -77,7 +78,10 @@ func inspect(name string, order map[string]bool, reader ethdb.AncientReader) (fr } // inspectFreezers inspects all freezers registered in the system. -func inspectFreezers(db ethdb.Database) ([]freezerInfo, error) { +func inspectFreezers(db ethdb.Database, opts ...InspectDatabaseOption) ([]freezerInfo, error) { + if options.As[inspectDatabaseConfig](opts...).skipFreezers { + return nil, nil + } var infos []freezerInfo for _, freezer := range freezers { switch freezer { diff --git a/core/rawdb/database.go b/core/rawdb/database.go index 1fc7bdc35fc..835a7f1c1ad 100644 --- a/core/rawdb/database.go +++ b/core/rawdb/database.go @@ -604,7 +604,7 @@ func InspectDatabase(db ethdb.Database, keyPrefix, keyStart []byte, opts ...Insp {"Light client", "Bloom trie nodes", bloomTrieNodes.Size(), bloomTrieNodes.Count()}, } // Inspect all registered append-only file store then. - ancients, err := inspectFreezers(db) + ancients, err := inspectFreezers(db, opts...) if err != nil { return err } diff --git a/core/rawdb/database.libevm.go b/core/rawdb/database.libevm.go index a7528b2618b..20ff2294e23 100644 --- a/core/rawdb/database.libevm.go +++ b/core/rawdb/database.libevm.go @@ -28,6 +28,7 @@ type inspectDatabaseConfig struct { statRecorders []func([]byte, common.StorageSize) bool isMetas []func([]byte) bool statsTransformers []func([][]string) [][]string + skipFreezers bool } func (c inspectDatabaseConfig) recordStat(key []byte, size common.StorageSize) bool { @@ -91,3 +92,10 @@ func WithDatabaseStatsTransformer(transform func(rows [][]string) [][]string) In c.statsTransformers = append(c.statsTransformers, transform) }) } + +// WithSkipFreezers returns an option that causes for freezer inspection to be skipped. +func WithSkipFreezers() InspectDatabaseOption { + return newInspectOpt(func(c *inspectDatabaseConfig) { + c.skipFreezers = true + }) +} diff --git a/core/rawdb/database.libevm_test.go b/core/rawdb/database.libevm_test.go index 684ab117738..548e08b558a 100644 --- a/core/rawdb/database.libevm_test.go +++ b/core/rawdb/database.libevm_test.go @@ -20,6 +20,9 @@ import ( "bytes" "fmt" "sort" + "testing" + + "github.com/stretchr/testify/require" "github.com/ava-labs/libevm/common" // To ensure that all methods are available to importing packages, this test @@ -28,6 +31,18 @@ import ( "github.com/ava-labs/libevm/ethdb" ) +func TestSkipFreezers(t *testing.T) { + require := require.New(t) + db := rawdb.NewMemoryDatabase() + + var ( + keyPrefix []byte + keyStart []byte + ) + + require.NoError(rawdb.InspectDatabase(db, keyPrefix, keyStart, rawdb.WithSkipFreezers())) +} + // ExampleDatabaseStat demonstrates the method signatures of DatabaseStat, which // exposes an otherwise unexported type that won't have its methods documented. func ExampleDatabaseStat() { From e4220c7ed41b6a4b6cf2933a86b7c5bce828dad9 Mon Sep 17 00:00:00 2001 From: Arran Schlosberg <519948+ARR4N@users.noreply.github.com> Date: Wed, 3 Sep 2025 16:34:48 +0100 Subject: [PATCH 139/142] refactor: `rawdb` tests (#221) ## Why this should be merged The need for examples to be in `package rawdb_test` made it difficult to test other code that relied on non-exported `rawdb` identifiers. ## How this works 1. Move all testable examples from `database.libevm_test.go` to `examples.libevm_test.go` _without any change_. 2. Change `database.libevm_test.go` to be in `package rawdb` and extend the `WithSkipFreezers()` test. ## How this was tested No change at all to testable examples. The `WithSkipFreezers()` test now touches both the happy and (specific) error paths to demonstrate exact behaviour (under the old approach it could have just been that there was no error, even without the option). --- core/rawdb/database.libevm_test.go | 206 +++-------------------------- core/rawdb/examples.libevm_test.go | 198 +++++++++++++++++++++++++++ 2 files changed, 219 insertions(+), 185 deletions(-) create mode 100644 core/rawdb/examples.libevm_test.go diff --git a/core/rawdb/database.libevm_test.go b/core/rawdb/database.libevm_test.go index 548e08b558a..2177e49f47b 100644 --- a/core/rawdb/database.libevm_test.go +++ b/core/rawdb/database.libevm_test.go @@ -14,200 +14,36 @@ // along with the go-ethereum library.
