[nodejs] Pass an int to a node.js addon

My original c++ function had the following signature unsigned char* random(int length); To use this as an add-on I modified it to Handle random(const Arguments& args) { if(args[0]->IsInt32()){ Local length = args[0]->ToInt32(); // Now here I want to create an array like this "unsigned char

Currently after removing one excessive call to Date.now makes the other Date.now call require as much time as all the other logic in setTimeout() + active() + all the _linklist stuff (L.isempty, L.remove, L.append, etc.). I think it can be better. Looking from another side, Date.now() can be ca

[nodejs] Being able to step through module code while debugging modules

Yes, it is a bit weird that crypto is sync and zlib is async. It'd be nice if we had a sync zlib API, and could move crypto stuff onto the thread pool, especially for TLS. On Fri, Oct 26, 2012 at 12:49 AM, Jimb Esser wrote: > That is exactly what node seems to do with the zlib API. Though there

That is exactly what node seems to do with the zlib API. Though there are times where this is great, this API definitely bothers me, and causes some problems. In theory, if I have a 4 core machine, and have 4 busy node processes, and each of them try to use the zlib API, suddenly I've got 8 c
