llnode update

gistfile1.md

Recent work

• Link with lldb reported by llvm-config on MacOS: no need to use the XCode one, can work with custom builds or lldb installed with Homebrew
• Fixed tests and Travis intergration
• LLNODE_DEBUG=true to print details of failures during symbol loading, turned on in Travis
• Loading symbols with shared libraries: can work with libv8 + d8 built with post-mortem support

JS API

• Original work by @rnchamberlain, rewrote with NAN and some API changes, e.g. use iterators for instance lists to save memory.
• Working now, has tests
• Looking for feedback on the API design: https://github.com/joyeecheung/llnode/blob/js-api/JSAPI.md
• Need reviews
• nodejs/llnode#147

Update to work with V8 6.4

• Metadata changes, probably some layout changes too: nodejs/llnode#158
• Backtrace & Map fixes: nodejs/llnode#168
• Object inspection is broken ATM due to metadata & descriptor changes, fixes in progress
• Currently we only have tests with Node.js v4, v6, v8 and v9 using Travis, need build intergration with Node.js master/PRs

Node.js Event Loop Inspection

• Upstream done by @mmarchini nodejs/node#14901 : adding nodedbg_* metadata for tools to restore internal structures of Node.js like the v8dbg_ metadata from V8
• llnode PR: nodejs/llnode#122
• Documentation: https://github.com/nodejs/node/blob/master/doc/guides/node-postmortem-support.md

Other Plans

• Work with more types: Errors, Symbols, etc.
• Better support for TypedArrays
• UTF8 string support
