List and analyze keys in memcache

# Writes a big file with one line per key
> bash dump_keys.sh > all-the-keys

# Get stats on the state of the whole key list
> cat all-the-keys | perl ./aggregate_keys.pl
count:2228244 size:86.50%  fetched:53.66%  bytesize:1948.7MB

Let the script know how big your cache is

Unlimited upload size in PHP

a minimal implementation

A demonstration of accepting unlimited-size uploads in PHP. The included server.php pipes the POST body directly to /dev/null and returns a JSON encoded hash of some useful stats. Using this method (streaming from stdin) we are able to accept uploads of any size with little memory overhead.

Setup

Symlink apache config and reload

// Allows easy composition of a chain of connect.js-style middlewares in node.js
// given:
// function A(req,res,next){}
// function B(req,res,next){}
// composeMiddleware(A,B) will return a function(req,res,next) that passes the request
// through both handlers,  just like Connect. If a next() is called with an error
// the call chain is stopped and the error is passed to the topmost next()
// If next() is called with the second parameter set to 'break' "next(null, 'break')"
// The chain is halted and route control is passed back to the original next()
