stream_wrap: add HandleScope's in uv callbacks #1078
Conversation
Ensure that no handles will leak into global HandleScope by adding HandleScope's in all JS-calling libuv callbacks in `stream_wrap.cc`. Fix: nodejs#1075
Don't forget to call `MakeWeak` to ensure that instance objects are garbage collectable.
Hold non-persistent reference in JS, rather than in C++ to avoid cycles.
Ensure no persistent-induced loops in C++-land by storing `SecureContext` reference in JS-land.
Seems to be fixing the issue, cc @bnoordhuis |

Captures all handles in this libuv callback? OnReadCommon
calls OnRead()
which might create handles.
LGTM with comments. I don't have time to test right now but this fixes all the test failures when you throw an |
Yep, it fixes all handle leaks. |

Notable changes: * buffer: New `Buffer#indexOf()` method, modelled off `Array#indexOf()`. Accepts a String, Buffer or a Number. Strings are interpreted as UTF8. (Trevor Norris) #561 * fs: `options` object properties in `'fs'` methods no longer perform a `hasOwnProperty()` check, thereby allowing options objects to have prototype properties that apply. (Jonathan Ong) #635 * tls: A likely TLS memory leak was reported by PayPal. Some of the recent changes in stream_wrap appear to be to blame. The initial fix is in #1078, you can track the progress toward closing the leak at #1075 (Fedor Indutny). * npm: Upgrade npm to 2.7.0. See npm CHANGELOG.md: https://github.com/npm/npm/blob/master/CHANGELOG.md#v270-2015-02-26 for details including why this is a semver-minor when it could have been semver-major. * TC: Colin Ihrig (@cjihrig) resigned from the TC due to his desire to do more code and fewer meetings.
