Steward fails on LiFX

[webchickbot]

My LiFX bulb was manually turned off and when I turned it back on it caused the steward to fail. I have reinstalled the steward and it still generates the same error -

LIFX connected.
Assertion failed: (handle->InternalFieldCount() > 0), function Unwrap, file ../src/node_object_wrap.h, line 61.
./run.sh: line 102: 23578 Abort trap: 6           node index.js

interesting. that sounds like node is corrupted on your system. let's start by unplugging the LIFX bulb and starting the steward and seeing if it crashes… thanks!

Yes - if I turn it off the light switch again manually, the steward comes up fine (I prefer not to remove it from the socket because it takes a ladder and a plank to physically reach it ... :-) )

@webchickbot - according to martynsmith/node-irc#178 we need to try running node v0.10.24, so try this:

    % nvm install v0.10.24
    % nvm alias default v0.10.24

and then restart the steward and see if you get a crash. thanks!

After doing a'git pull', there is also the 'npm -l install' one layer below.. (-;

gak - I knew that. Not enough coffee.

Should I change the docs here to include the newer version of node.js?

Hold the phone … I turned on the LiFX and I still get

LIFX connected.

i defer to @aallan as to whether to update the docs for the new version. perhaps when we do the next release, we should do that.

with respect to the crash. this is in the node internals, and although the upgrade worked for at least one person, it's not working for you. i doubt that i can put together a simple test case to reliably get a failure, so you may have to live without lifx for a while until we can track it down… sorry!

[mrose17]

unable to reproduce, etc.

[mrose17]

it turns out that this (sometimes) happens in mavericks because of "use strict" in the node-clone module. until they get a fix, we'll use a different deep cloning module in the lifx module...
