Rebuilt automatically whenever the revision Chrome uses changes.\n\n![build](https://github.com/tinysec/skia-asan/actions/workflows/build.yml/badge.svg)\n![track](https://github.com/tinysec/skia-asan/actions/workflows/track.yml/badge.svg)\n![release](https://img.shields.io/github/v/release/tinysec/skia-asan?label=release)\n\n## Staying current\n\n`chrome.lock` pins the exact Skia revision a specific Chrome stable version\nships (Skia is pinned directly in Chrome DEPS). The\n[`track-chrome`](.github/workflows/track.yml) workflow runs every 6 hours: it\nresolves the latest Chrome stable, reads the Skia SHA from Chrome DEPS, and\nwhen it has changed it bumps `chrome.lock`, tags `skia-\u003csha8\u003e`, and\ntriggers [`build`](.github/workflows/build.yml). Each `skia-\u003csha8\u003e` tag\nbecomes a GitHub release.\n\n## Release artifacts\n\nEach release is published at its `skia-\u003csha8\u003e` tag as **one zip per\nplatform** (so the full `include/` header tree is preserved without name\ncollisions in GitHub's flat asset namespace). Each zip contains:\n\n- `lib/libskia.a` (Linux) / `lib/skia.lib` (Windows): the ASAN **static**\n  Skia library — link it into your own harness. This is the primary artifact\n  for fuzzing. (Skia is shipped static only; no dynamic ASAN lib.)\n- `lib/include/`: the full Skia public header tree.\n- `fuzz/fuzz` (Linux only): the Skia multiplexed fuzz driver (own `main()`,\n  replays seed files). Windows omits it: Skia's GN leaves `is_clang=false` for\n  the MSVC-ABI toolchain, so the `assert(is_clang)` fuzz-driver targets are\n  unavailable there. SanitizerCoverage stays on via `fuzzer-no-link` so a\n  downstream libFuzzer / WinAFL harness still gets coverage feedback.\n\n## ASAN runtime model\n\nBoth platforms link the **static** ASAN runtime (depot_tools' bundled clang\nships the full static sanitizer runtime). The libraries and the `fuzz` driver\nare self-contained — no `clang_rt.asan_dynamic` DLL is needed at runtime.\n\n## Fuzzing\n\n- **Linux:** `fuzz/fuzz` is a ready-to-run ASAN fuzz executable with its own\n  `main()` (replays seeds, not a libFuzzer engine).\n- **Windows (AFL++ / WinAFL):** link `lib/skia.lib` into a harness exposing a\n  target function, then point WinAFL at that function. The static ASAN lib is\n  self-contained.\n\n\u003e These builds provide the ASAN-instrumented library to target. They do not\n\u003e bundle the AFL++ / WinAFL runner itself (a separate DynamoRIO-based\n\u003e toolchain on Windows).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftinysec%2Fskia-asan","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftinysec%2Fskia-asan","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftinysec%2Fskia-asan/lists"}
