From e999be0315fc8774cbf4fd405a8aa59687cbb3cd Mon Sep 17 00:00:00 2001 From: Claude Bot Date: Tue, 4 Nov 2025 00:33:09 +0000 Subject: [PATCH] Phase 7 Step 4 Part 1: Move main thread fields to MainThreadData struct MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Migrates fields that are only accessed from the main JavaScript thread into a dedicated MainThreadData struct for clearer thread safety boundaries. Fields moved (11 total): - global_this, javascript_vm, promise - response_weak, native_response, readable_stream_ref - abort_signal, check_server_identity - poll_ref, concurrent_task, tracker Changes: - Enabled MainThreadData struct definition with full documentation - Added main_thread: MainThreadData field to FetchTasklet - Removed individual field declarations from FetchTasklet - Updated 50+ access sites to use this.main_thread.field_name pattern - Updated initialization in get() method - Updated cleanup to call main_thread.deinit() - Added assertMainThread() helper for debug builds This separation makes thread access patterns explicit and improves code organization by grouping main-thread-only data together. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/bun.js/webcore/fetch/FetchTasklet.zig | 271 +++++++++++----------- 1 file changed, 132 insertions(+), 139 deletions(-) diff --git a/src/bun.js/webcore/fetch/FetchTasklet.zig b/src/bun.js/webcore/fetch/FetchTasklet.zig index a3af86e9f9..d680354a34 100644 --- a/src/bun.js/webcore/fetch/FetchTasklet.zig +++ b/src/bun.js/webcore/fetch/FetchTasklet.zig @@ -389,7 +389,7 @@ pub const FetchTasklet = struct { reason.ensureStillAlive();
