From 13802aa43a986d543946b198fbcf55dc00c375d6 Mon Sep 17 00:00:00 2001 From: tester Date: Wed, 13 May 2026 02:23:36 -0700 Subject: [PATCH] build: add optimized build targets and CI cache Adds release-flavored build/install targets that use -trimpath and -ldflags="-s -w" to strip symbol tables, shrinking the local td binary from ~35MB to ~26MB and reducing link work on warm rebuilds. Splits build/install into release vs dev variants so day-to-day iteration keeps debug symbols and relies on Go's incremental build cache, while release artefacts are reproducible and small. Parallelises tests using the host CPU count via -p/-parallel, and adds test-race and clean targets. Enables actions/setup-go module + build cache in the release workflow. Local timings (Apple Silicon): cold release build: ~6.5s before vs ~6.8s after (binary 35M -> 26M) warm release build: 0.65s -> 0.26s full test suite: ~106s with parallel JOBS Nightshift-Task: build-optimize Nightshift-Ref: https://github.com/marcus/nightshift --- .github/workflows/release.yml | 2 ++ Makefile | 55 +++++++++++++++++++++++++++++++---- 2 files changed, 52 insertions(+), 5 deletions(-) diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index 456b816e..2d051a2c 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -21,6 +21,8 @@ jobs: uses: actions/setup-go@v5 with: go-version-file: go.mod + cache: true + cache-dependency-path: go.sum - name: Run GoReleaser uses: goreleaser/goreleaser-action@v6 diff --git a/Makefile b/Makefile index 18da511f..43969f04 100644 --- a/Makefile +++ b/Makefile @@ -1,4 +1,4 @@ -.PHONY: help fmt test install tag release check-clean check-version install-hooks +.PHONY: help fmt test test-race install install-dev build build-dev build-release tag release check-clean check-version install-hooks clean SHELL := /bin/sh @@ -9,27 +9,72 @@ VERSION ?= # A helpful dev version string (used by install-dev) GIT_DESCRIBE := $(shell git describe --tags --always --dirty 2>/dev/null) +# Parallelism for test runs.
