1.31.0 (2024-01-16)

Bug Fixes

• apply acceptable bounds into max-parallelism (084e79a)
• bump up rust builder image into 1.74.1 (cc97e1c)
• check retiring workers more strictly (a0b5688)
• cpu_timer: minimize unsoundness for ffi routines (3a11551)
• cpu_timer: polishing (9b2d794)
• cpu_timer: there is no specification at POSIX that the timer id in the buffer should be saved as a non-zero id (858afe0)
• don't leave pending requests orphan state for a long time (63aff04)
• don't register the signal handler while unit testing (aab5fd4)
• don't use cpu timer when unit testing (b870346)
• drop the runtime after receiving the termination event (f602313)
• handle abnormal connection closure correctly (04c59c6)
• logging unexpected event loop escape explicitly (91b9d0e)
• make all unit test pass (c4a4b63)
• make cpu timer not to be re-armed in per_request policy (5f271aa)
• make perform sync between supervisor and pooler correctly in per_worker policy (10f3f9b)
• missing null check in nextRequest shim (03f3899)
• oops 🙄 (ace1057)
• oops 🙄 (047a6d7)
• polishing runtime entrypoint (b775128)
• polishing supervisor nits (299beb9)
• pooler needs to consider force creation mode (a088f3c)
• relaxing connection watcher restriction (a187692)
• remove error spam (ade9298)
• request creation task must be synchronized with the supervisor when entering the job (58cc591)
• rid flakiness of integration tests (f111403)
• supervisor must wake up the worker's event loop to terminate an isolate correctly (8ea2b37)
• use available_parallelism as default maximum parallelism value (65ef283)

Features

• allowing cpu timer to be reset from another thread (52af11c)
• introduce oneshot supervisor policy (80313e7), closes supabase/edge-runtime#192 supabase/edge-runtime#212
• make CPU time limit optional (14f75b0)
• supervisor need to track lifetime of requests to perform early termination of worker (b4a0834)

Performance Improvements

• make advance the sending of the request end signal timing earlier (6567af7)
• partially recovers the regression of request throughput on the per_worker policy (555cf5a)
