| ## Action Items | ||
|
|
||
| The following action items are copied from [this Google Doc](https://docs.google.com/document/d/1ftJCXFM_Yi45O2nr5O7YwdOMO7iUbWSx-UStvOYMu28/edit) | ||
|
|
||
| Besides these action items, there aren't any proper minutes. | ||
| For the best overview see the Recordings section below. | ||
|
|
||
| ### Async Hooks | ||
|
|
||
| Lead: [Matteo Collina](https://github.com/mcollina) | ||
|
|
||
| - Agreement on Benedikt's [document](http://bit.ly/making-async-hooks-fast-enough) (ASAP) | ||
| - This solves the performance issue | ||
| - *Please read and comment* | ||
| - Should there be a higher level API for CLS? | ||
| - Vladmir started working on a PR to add CLS to Core | ||
|
|
||
| ### V8 Signals | ||
|
|
||
| Lead: [Yang Guo](https://github.com/hashseed) | ||
|
|
||
| - [Document](https://docs.google.com/document/d/1xHl4qF2olKtDEPQFkci8g_wF3oTA-NBoJ6z5cpw1PWk) | ||
| - There are more trace events that V8 could be emitting | ||
| - Low-hanging fruit: opt/deopt events | ||
| - Identify more use cases | ||
| - Move command line flags to actual APIs | ||
|
|
||
| ### Documentation and Best Practices | ||
|
|
||
| Lead: [Michael Dawson](https://github.com/mhdawson) | ||
|
|
||
| - Continue to refine the list of use cases | ||
| - Continue to fill those in | ||
| - Move heapdump generation to core ([@jasnell](https://github.com/jasnell)) | ||
| - Write best practices guide based on that | ||
|
|
||
| ### Postmortem Debugging | ||
|
|
||
| Lead: [Yang Guo](https://github.com/hashseed) | ||
|
|
||
| - Move V8 to Torque (DSLification) | ||
| - WIP | ||
| - There's a spreadsheet with the progress | ||
| - Move llnode to use the metadata/script generated from DSL | ||
| - Heapsnapshot | ||
| - Additional tooling to help uncover issues aside from core dump | ||
| - Also convert core dump to heapsnapshot | ||
|
|
||
| ### Trace Events and System Tracing | ||
|
|
||
| Lead: [James M Snell](https://github.com/jasnell) | ||
|
|
||
| - Perfetto: moving forward | ||
| - `TRACE_EVENTS` will be our primary instrumentation path | ||
| - System tracing will be case-by-case, best effort approach | ||
| - Open an issue notifying stakeholders of this decision ([@jasnell](https://github.com/jasnell)) | ||
| - Start to instrument more areas of core | ||
| - Profiling: doc to circulate ([@psmarshall](https://github.com/psmarshall)) | ||
| - A flag similar to --prof but based on the CPU Profiler ([@joyeecheung](https://github.com/joyeecheung)) | ||
|
|
||
| ### APM Instrumentation | ||
|
|
||
| - V8 exposing a new API is not what we need | ||
| - We need to figure out what APM vendors want | ||
| - Come up with a blessed instrumentation API for module vendors to instrument their modules | ||
| - Document on monkey-patching vs. ESM | ||
|
