To Review

  • Release v4.0.0 – Codename Krampack
  • Fixed issues in windows thread switching by implementing thread attach for w32dbg =!pid
  • Previously the function attempted to OpenProcess even though the main
  • pid is already opened by __open and the fact that re-opening the main
  • pid wouldn’t do anything. This way it attaches to new threads when
  • called by r_debug_select.
  • Modified w32_continue to update rio->pi.dwThreadId after switching to the requested thread\xa0##debug
  • Manually changing iop->pi.dwThreadId in io_w32dbg’s =!pid created a
  • problematic scenario when w32_continue is called with the last event’s
  • tid from dbg_wait. This solution makes sure iop->pi.dwThreadId keeps
  • being updated after events on other threads arrive and that w32_continue
  • actually uses the given tid.
  • Modified w32_continue return values
  • Fix build
