LGTM but can you fix up the Reviewed-By tags? Also, the tags are missing in the last commit; the original (a53b2ac) has them. |

Cleanup how node_contextify keeps weak references in order to prepare for new style phantom weakness API. We didn't need to keep a weak reference to the context's global proxy, as the context holds it. PR-URL: nodejs#5392 Reviewed-By: Ben Noordhuis <[email protected]>
Simplify how node_contextify was keeping a weak reference to the sandbox object in order to prepare for new style phantom weakness V8 API. It is simpler (and more robust) for the context to hold a reference to the sandbox in an embedder data field. Doing otherwise meant that the sandbox could become weak while the context was still alive. This wasn't a problem because we would make the reference strong at that point. Since the sandbox must live at least as long as the context, it would be better for the context to hold onto the sandbox. PR-URL: nodejs#5392 Reviewed-By: Ben Noordhuis <[email protected]>

When the previous set of changes (bfff07b) it was possible to have the context get garbage collected while sandbox was still live. We need to tie the lifetime of the context to the lifetime of the sandbox. This is a backport of nodejs#5786 to v5.x.

Thanks @bnoordhuis, all fixed now. CI is all green except for test-debug-port-cluster on FreeBSD which is apparently fixed on master by #6769 which I have flagged for lts-watch. @thealphanerd what's the chance of this getting in to the next v4.x? Are we running too close to make it in? |

landed in v4.x-staging |

@rvagg considering the amount of testing these changes received I see no problem with including it in the next release. I've added them to the proposal branch and am just running tests / cutting a new RC right now |

Original issue: #3113
Backports #5786 & #5786 together to v4.x-staging. This combination was tested by users with a v4.x build @ #3113 (comment), we said we'd backport it properly but were waiting for a solid proving time in v5.x because of some problems we had (the bug that #5786 fixed).
Backported to 5.x in #5800 and was released in v5.9.1 / 2016-03-23 with no additional problems beyond #5786. IMO this is ready to roll into the next v4.x.
