## Changes

| Change | Before | Now |
|---|---|---|
| **Per-target build sub-workflows** | <ul><li>Getting a reusable build
depended on all builds completing.</li><li>Even if e.g. a macOS build is
cached, the waiting workflow with macOS runners could be queued for a
long time just to get the status and cache of the other workflow, since
macOS runners are more scarce than e.g. Ubuntu.</li></ul> |
<ul><li>Split umbrella `reusable-build.yml` into
`reusable-build-{linux,macos,windows,wasm}.yml`.</li><li>Consumers can
wait on a specific target and start earlier instead of blocking on the
whole matrix.</li><li>E.g. E2E and the compile-and-hash matrix start
earlier (gate only on the targets needed).</li></ul> |
| **Bottleneck macOS Intel only running on `main`** | macOS Intel
runners are 2-3× slower than macOS ARM for the contract compilation
tests. Ran on each PR, being the bottleneck. | This build is now
excluded from the matrix for PR runs, and only included for pushes to
`main`. |
| **E2E tests use higher concurrency** | `run-e2e-tests` duration:
~43min.</li></ul> | <ul><li>Uses higher number of concurrent tasks, made
possible by retester flakiness fix.</li><li>`run-e2e-tests` duration:
~16min.</li></ul> |
| **Faster LLVM downloads** | Building resolc took ~8-13min (~16 min on
macOS intel). | `get-llvm/action.yml` uses more efficient version
detection. Building resolc now takes ~2min (~4-7 min on macOS intel). |
| **Wasm tests use cached artifacts** | `test-wasm.yml` ran its own
duplicate build. | `test-wasm.yml` uses the reusable Wasm build. |
| **Skip unnecessary polkadot-sdk package** | For E2E tests,
`polkadot-omni-node` was unconditionally downloaded (~3-4min). | Only
`pallet-revive-eth-rpc` and `revive-dev-node` are downloaded from the
cache. |
| **Cache `report-processor`** | Only `retester` was cached. |
`report-processor` is cached for the compilations and export hashes
jobs. |
| **Hardhat unblocked from differential tests** | Started after the
differential tests succeeded in order to reuse the Linux build. | Starts
as soon as the required `test` job succeeds, using the reusable Linux
build. |
| **Conditionally skip workflows** | <ul><li>Some workflows
conditionally skipped for md-only changes.</li><li>Tooling-only changes
also ran e.g. `test-wasm.yml` and `differential-tests.yml`.</ul></li> |
<ul><li>Most workflows are skipped for doc-only
updates.</li><li>Tooling-only updates trigger only the respective
tooling test (Hardhat), apart from the required `test`
job.</li><li>Differential tests are skipped for js-only
updates.</li></ul> |
| **Miscellaneous** | <ul><li>Used actions running on soon-deprecated
Node 20.</li><li>Difficult to debug Playwright `test-wasm`
failures.</li></ul> | <ul><li>Upgraded actions that used Node
20.</li><li>Added Playwright debug traces uploaded on `test-wasm`
failures.</li></ul> |
