From 429c79ff0956ab2d2fa58316b4eddd5d04d26fea Mon Sep 17 00:00:00 2001 From: Claude Bot Date: Thu, 25 Sep 2025 15:29:22 +0000 Subject: [PATCH] fix: respect install.lockfile.save=false when migrating from package-lock.json MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Previously, Bun would always save a lockfile when migrating from package-lock.json or yarn.lock, even when install.lockfile.save was set to false in bunfig.toml. This fix ensures that the save=false configuration is respected during migration. The lockfile is still migrated and used in memory for dependency resolution, but it is not written to disk when save=false.
