Concurrency in golang and a mini Load-balancer

INTRO

Concurrency is a domain I have wanted to explore for a long time because the locks and the race conditions have always intimidated me. I recall somebody suggesting concurrency patterns in golang because they said "you share the data and not the variables".

Amused by that, I searched for "concurrency in golang" and bumped into this awesome slide by Rob Pike: https://talks.golang.org/2012/waza.slide#1 which does a great job of explaining channels, concurrency patterns and a mini-architecture of load-balancer (also explains the above one-liner).

Let's dig in:

Standalone (Play Store only) go-iap for GAE
package yourgaeproject
// go-iap doesn't work for GAE since we need to use urlfetch
//
// Copy this source file to your GAE to your project.
//
// The API is mostly the same as go-iap. I prefixed some stuff since this file lives within my GAE project's package.

Benchmarking Nginx with Go

Benchmarking Nginx with Go

There are a lot of ways to serve a Go HTTP application. The best choices depend on each use case. Currently nginx looks to be the standard web server for every new project even though there are other great web servers as well. However, how much is the overhead of serving a Go application behind an nginx server? Do we need some nginx features (vhosts, load balancing, cache, etc) or can you serve directly from Go? If you need nginx, what is the fastest connection mechanism? This are the kind of questions I'm intended to answer here. The purpose of this benchmark is not to tell that Go is faster or slower than nginx. That would be stupid.

So, these are the different settings we are going to compare:

  • Go HTTP standalone (as the control group)
  • Nginx proxy to Go HTTP
  • Nginx fastcgi to Go TCP FastCGI
  • Nginx fastcgi to Go Unix Socket FastCGI

Simple PHP script showing how to send an Android push notification. Be sure to replace the API_ACCESS_KEY with a proper one from the Google API's Console page. To use the script, just call scriptName.php?id=THE_DEVICE_REGISTRATION_ID

// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'YOUR-API-ACCESS-KEY-GOES-HERE' );

# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
# the WebSocket protocol implementation in the cramp gem does not work
# well with Chrome's (newer) WebSocket implementation.
