From df6b9c67609924712c85616a4e48b2db98bd1470 Mon Sep 17 00:00:00 2001 From: Eric <5089238+emizzle@users.noreply.github.com> Date: Wed, 20 Dec 2023 08:06:24 +1100 Subject: [PATCH] Workaround for Hardhat last block timestamp bug (#644) * Workaround for Hardhat timestamp bug Likely due to a Hardhat bug in which the callbacks for subscription events are called and awaited before updating its local understanding of the last block time, Hardhat will report a block time in the `newHeads` event that is generally 1 second before the time reported from `getLatestBlock.timestamp`. This was causing issues with the OnChainClock's offset and therefore the `now()` used by the `OnChainClock` would sometimes be off by a second (or more), causing tests to fail. This commit introduce a `codex_use_hardhat` compilation flag, that when set, will always get the latest block timestamp from Hardhat via the `getLatestBlock.timestamp` RPC call for `OnChainClock.now` calls. Otherwise, the last block timestamp reported in the `newHeads` event will be used. Update the docker dist tests compilation flag for simulated proof failures (it was not correct), and explicitly add the `codex_use_hardhat=false` for clarity. * enable simulated proof failures for coverage * comment out failing test on linux -- will be replaced * bump codex contracts eth * add back clock offset for non-hardhat cases * bump codex-contracts-eth increases pointer by 67 blocks each period increase * Add `codex_use_hardhat` flag to coverage tests --- .github/workflows/docker-dist-tests.yml | 2 +- build.nims | 6 ++-- codex/conf.nim | 1 + codex/contracts/clock.nim | 28 ++++++++++++--- config.nims | 2 -- tests/contracts/testClock.nim | 14 -------- tests/integration/testIntegration.nim | 48 +++++++++++++------------ vendor/codex-contracts-eth | 2 +- 8 files changed, 56 insertions(+), 47 deletions(-) diff --git a/.github/workflows/docker-dist-tests.yml b/.github/workflows/docker-dist-tests.yml index e6e0973b..5ae2e30a 100644 --- a/.github/workflows/docker-dist-tests.yml +++ b/.github/workflows/docker-dist-tests.yml @@ -24,7 +24,7 @@ jobs: name: Build and Push uses: ./.github/workflows/docker-reusable.yml with: - nimflags: '-d:disableMarchNative -d:codex_enable_api_debug_peers=true -d:codex_enable_simulated_proof_failures -d:codex_enable_log_counter=true' + nimflags: '-d:disableMarchNative -d:codex_enable_api_debug_peers=true -d:codex_enable_proof_failures=true -d:codex_use_hardhat=false -d:codex_enable_log_counter=true' nat_ip_auto: true tag_latest: ${{ github.ref_name == github.event.repository.default_branch || startsWith(github.ref, 'refs/tags/') }} tag_suffix: dist-tests diff --git a/build.nims b/build.nims index 741484a6..11eec387 100644 --- a/build.nims +++ b/build.nims @@ -25,13 +25,13 @@ task codex, "build codex binary": buildBinary "codex", params = "-d:chronicles_runtime_filtering -d:chronicles_log_level=TRACE" task testCodex, "Build & run Codex tests": - test "testCodex", params = "-d:codex_enable_proof_failures=true" + test "testCodex", params = "-d:codex_enable_proof_failures=true -d:codex_use_hardhat=true" task testContracts, "Build & run Codex Contract tests": test "testContracts" task testIntegration, "Run integration tests": - buildBinary "codex", params = "-d:chronicles_runtime_filtering -d:chronicles_log_level=TRACE -d:codex_enable_proof_failures=true" + buildBinary "codex", params = "-d:chronicles_runtime_filtering -d:chronicles_log_level=TRACE -d:codex_enable_proof_failures=true -d:codex_use_hardhat=true" test "testIntegration" task build, "build codex binary": @@ -75,7 +75,7 @@ task coverage, "generates code coverage report": if f.endswith(".nim"): nimSrcs.add " " & f.absolutePath.quoteShell() echo "======== Running Tests ======== " - test "coverage", srcDir = "tests/", params = " --nimcache:nimcache/coverage -d:release " + test "coverage", srcDir = "tests/", params = " --nimcache:nimcache/coverage -d:release -d:codex_enable_proof_failures=true -d:codex_use_hardhat=true" exec("rm nimcache/coverage/*.c") rmDir("coverage"); mkDir("coverage") echo " ======== Running LCOV ======== " diff --git a/codex/conf.nim b/codex/conf.nim index 9dc3cb8d..4a0e70f4 100644 --- a/codex/conf.nim +++ b/codex/conf.nim @@ -45,6 +45,7 @@ export net, DefaultQuotaBytes, DefaultBlockTtl, DefaultBlockMaintenanceInterval, const codex_enable_api_debug_peers* {.booldefine.} = false codex_enable_proof_failures* {.booldefine.} = false + codex_use_hardhat* {.booldefine.} = false codex_enable_log_counter* {.booldefine.} = false type diff --git a/codex/contracts/clock.nim b/codex/contracts/clock.nim index 23b678e9..d5f2f4ee 100644 --- a/codex/contracts/clock.nim +++ b/codex/contracts/clock.nim @@ -3,9 +3,13 @@ import pkg/ethers import pkg/chronos import pkg/stint import ../clock +import ../conf export clock +logScope: + topics = "contracts clock" + type OnChainClock* = ref object of Clock provider: Provider @@ -13,6 +17,7 @@ type offset: times.Duration started: bool newBlock: AsyncEvent + lastBlockTime: UInt256 proc new*(_: type OnChainClock, provider: Provider): OnChainClock = OnChainClock(provider: provider, newBlock: newAsyncEvent()) @@ -20,29 +25,44 @@ proc new*(_: type OnChainClock, provider: Provider): OnChainClock = method start*(clock: OnChainClock) {.async.} = if clock.started: return - clock.started = true proc onBlock(blck: Block) {.upraises:[].} = let blockTime = initTime(blck.timestamp.truncate(int64), 0) let computerTime = getTime() clock.offset = blockTime - computerTime + clock.lastBlockTime = blck.timestamp clock.newBlock.fire() if latestBlock =?
