From 5a6b9118f52761f97c940663d4e159060278cb9c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Dean=20Qui=C3=B1anola?= Date: Fri, 11 Oct 2024 21:56:42 -0700 Subject: [PATCH] Blocking job take call means 5-sec debounce no longer needed (#366) Fix: This was causing unnecessary delays in serverless workers. Refactored rp_job.get_job to work well under pause and unpause conditions. More debug lines too. Refactored rp_scale.JobScaler to handle shutdowns where it cleans up hanging tasks and connections gracefully. Better debug lines. Fixed rp_scale.JobScaler from unnecessary long asyncio.sleeps made before considering the blocking get_job calls. Improved worker_state's JobProgress and JobsQueue to timestamp when jobs are added or removed. Incorporated the lines of code in worker.run_worker into rp_scale.JobScaler where it belongs and simplified to job_scaler.start() Fixed non-error logged as errors in tracer Updated unit tests mandating these changes --- runpod/serverless/modules/rp_job.py | 77 ++++---- runpod/serverless/modules/rp_scale.py | 146 +++++++++++---- runpod/serverless/modules/worker_state.py | 8 + runpod/serverless/worker.py | 31 +--- runpod/tracer.py | 8 +- .../test_serverless/test_modules/test_job.py | 168 ++++++------------ tests/test_serverless/test_worker.py | 147 +++++++++------ 7 files changed, 316 insertions(+), 269 deletions(-) diff --git a/runpod/serverless/modules/rp_job.py b/runpod/serverless/modules/rp_job.py index 6d7e647e..9344b00e 100644 --- a/runpod/serverless/modules/rp_job.py +++ b/runpod/serverless/modules/rp_job.py @@ -2,7 +2,6 @@ Job related helpers.
