From 06453a94a7b06df30be0148e8b1d89932350f677 Mon Sep 17 00:00:00 2001 From: Timothy J Fontaine Date: Mon, 3 Mar 2014 16:27:58 -0800 Subject: [PATCH] src: domain should not replace nextTick function Previously if you cached process.nextTick and then require('domain') subsequent nextTick() calls would not be caught because enqueued functions were taking the wrong path. This keeps nextTick to a single function reference and changes the implementation details after domain has been required. --- src/node.cc | 2 +- src/node.js | 8 ++++++-- test/message/max_tick_depth_trace.out | 2 ++ test/simple/test-next-tick-domain.js | 29 +++++++++++++++++++++++++++ 4 files changed, 38 insertions(+), 3 deletions(-) create mode 100644 test/simple/test-next-tick-domain.js diff --git a/src/node.cc b/src/node.cc index a18e0d89d5c..ac906f0cd5c 100644 --- a/src/node.cc +++ b/src/node.cc @@ -918,7 +918,7 @@ Handle UsingDomains(const Arguments& args) { Local tdc = tdc_v.As(); Local ndt = ndt_v.As(); process->Set(String::New("_tickCallback"), tdc); - process->Set(String::New("nextTick"), ndt); + process->Set(String::New("_currentTickHandler"), ndt); process_tickCallback.Dispose(); // Possibly already set by MakeCallback(). process_tickCallback = Persistent::New(tdc); return Undefined(); diff --git a/src/node.js b/src/node.js index bdbe1c5e16d..b54ff51752a 100644 --- a/src/node.js +++ b/src/node.js @@ -331,8 +331,12 @@ var index = 1; var depth = 2; - process.nextTick = nextTick; + process.nextTick = function nextTick(cb) { + process._currentTickHandler(cb); + }; + // needs to be accessible from cc land + process._currentTickHandler = _nextTick; process._nextDomainTick = _nextDomainTick; process._tickCallback = _tickCallback; process._tickDomainCallback = _tickDomainCallback; @@ -472,7 +476,7 @@ tickDone(0); } - function nextTick(callback) { + function _nextTick(callback) { // on the way out, don't bother. it won't get fired anyway. if (process._exiting) return; diff --git a/test/message/max_tick_depth_trace.out b/test/message/max_tick_depth_trace.out index 22184a69119..c9db2c5580a 100644 --- a/test/message/max_tick_depth_trace.out +++ b/test/message/max_tick_depth_trace.out @@ -10,6 +10,7 @@ tick 12 tick 11 Trace: (node) warning: Recursive process.nextTick detected.
