Quickly download a repo at a ref without git history, useful if you need multiple tag/commit/branch of it
REF=8680bb9
# The following work as well
# REF=master
# REF=V8.x-staging
# REF=V8.9.1
wget https://github.com/nodejs/node/archive/$REF.tar.gz
mkdir -p $REF
tar zxvf $REF.tar.gz -C $REF --strip-components=1
cd $REF

llnode update

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.
