Pi-Bolt 0.9.4: upstream Bun and WebKit fixes - #50
Conversation
Bun (cherry-picked onto the pinned commit, before Pi-Bolt's patch): - startup SIGILL on Linux arm64 when SVE2 is reported without SVE (oven-sh/bun#45099) - fetch sets up TLS once per connection (oven-sh/bun#44507) - stdout/stderr: O_NONBLOCK cleared for spawned children, no output dropped on EAGAIN (oven-sh/bun#43868) - a socket whose peer keeps the receive buffer full no longer stops timers (oven-sh/bun#45278) - PipeReader after a failed read (oven-sh/bun#43900), spawnSync (oven-sh/bun#44581) - TextEncoder.encode of a substring (oven-sh/bun#45281) - fetch over HTTP/2 after a TLS alert or an abort (oven-sh/bun#45422) - mimalloc 3.5.3 (oven-sh/bun#44560, oven-sh/bun#44575) WebKit (appended to the patch series): - a module removed while its import() is in flight (oven-sh/WebKit#748) - cgroup v2 limits beside a cgroup v1 hierarchy (oven-sh/WebKit#808) Test-file conflicts were resolved to the pinned tests; the source changes are as upstream.

Pi-Bolt 0.9.4: fixes from upstream Bun and WebKit in the engine. Pi is unchanged from 0.9.3.
patches/bun.patch: ten upstream Bun fixes cherry-picked onto the pinned commit, before Pi-Bolt's patch: the ARM64 startup SIGILL (Fix startup SIGILL on Linux arm64 when SVE2 is reported without SVE oven-sh/bun#45099), fetch TLS per connection (fetch: set up TLS once per connection, not once per request oven-sh/bun#44507), child stdio (process.stdout/stderr: clear O_NONBLOCK for spawned children, don't drop console output on EAGAIN oven-sh/bun#43868), timers under a full receive buffer (sockets: a peer that keeps the receive buffer full no longer stops timers oven-sh/bun#45278), PipeReader (PipeReader: do not read an fd again after a read on it fails oven-sh/bun#43900), spawnSync (spawnSync: stop pointing the VM at the loop it waits on oven-sh/bun#44581), TextEncoder (TextEncoder: fixencodeof a substring whose parent string changed width oven-sh/bun#45281), HTTP/2 after an abort (fetch over HTTP/2: reject on a TLS alert after the handshake, and stop using a connection that went silent after an abort oven-sh/bun#45422), mimalloc 3.5.3 (Bump mimalloc: faster heaps, less purge churn; release memory during Bun.sleepSync oven-sh/bun#44560, Bump mimalloc: upstream v3.5.3 oven-sh/bun#44575).patches/webkit.patch: [JSC] removeEntry() and clearAll() keep the realm's [[LoadedModules]] in step with the registry oven-sh/WebKit#748 (import() of a removed module) and WTF: see the cgroup v2 limits where a cgroup v1 hierarchy exists beside it oven-sh/WebKit#808 (cgroup v2 beside v1) appended. [JSC] Return free memory sooner: idle worker threads, Atomics.wait oven-sh/WebKit#768 (idle threads return memory) is already in the pinned WebKit.Runtimes: run 38928351471, all four built and passed tests/aot and tests/runtime. Benchmark (bench/bun-fixes, run 38936377885; same Pi on 0.9.3's and 0.9.4's runtime, one CPU): startup peak memory 53 to 42 MB on x86-64, 42 to 39 MB on ARM64; everything else within a few percent.
