From a7630976bf0740c8233701e90fcec8c71614c813 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 15 May 2026 20:22:21 +0000 Subject: [PATCH] perf: optimize CmdStan version resolution to bypass GitHub API Optimized the GitHub API call in `src/cmdstan/install.sh` to fix a known inefficiency. This prevents rate-limiting issues when users build the devcontainer. - Pinned the default fallback version to "2.36.0" instead of making API calls out of the box. - Updated resolution of `latest` requests to use `curl`'s lightweight redirect-following (`url_effective`) rather than fetching the full GitHub API JSON, greatly speeding up version resolution and completely avoiding the API quota. - Included fallback mechanism if the fast lookup fails. - Updated documentation.
