The plan is as follows:\n\n1. Add `emscripten_version.txt` file and add `--emsdk-cache` argument to `emscripten/__main__.py`. If `--emsdk-cache` is passed, the build script will require that the appropriate emsdk version is found in that directory.\n2. Backport this to 3.14.x\n3. Set up buildbot cache dir\n4. Make a PR to buildmaster config to pass the `--emsdk-cache` argument\n\ncc @freakboy3742 \n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-145180\n* gh-145582\n* gh-146156\n* gh-146158\n* gh-146159\n* gh-146160\n* gh-146184\n* gh-146186\n* gh-150874\n* gh-150894\n* gh-150895\n* gh-150896\n* gh-150926\n* gh-150939\n* gh-151421\n* gh-151611\n* gh-153235\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/hoodmane","@type":"Person","name":"hoodmane"},"datePublished":"2026-02-24T13:25:11.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":11},"url":"https://github.com/145177/cpython/issues/145177"}
