I have an app that works fine on my dev machine (osx, local memcached) but
when I move it to appengine it fails. I tracked it to memcache not storing
objects over about 3.5k.
Here is a little test that runs under express. It takes a length value
makes a buffers, sends it to memcache and tries to get it back. It works
fine locally up to the expected 1MB limit, however on appengine it fails at
around length 3600 +/- 200 (it varies, which is really odd). I've tried
several different memcache libs, they all fail the same way.
What am I missing?
//memcache test.
app.get('/mct/:len',function(req,res) {
var memcachedAddr = process.env.MEMCACHE_PORT_11211_TCP_ADDR || 'localhost';
var memcachedPort = process.env.MEMCACHE_PORT_11211_TCP_PORT || '11211';
var memcacheServer = memcachedAddr + ":" + memcachedPort;
var Memcached = require('memcached');
var client = new Memcached(memcacheServer);
var len = req.params.len * 1; //lazy cast to int
var text = new Array(len + 1).join( " " );
try {
client.set("testkey",text,600,function(err,val) {
client.get("testkey",function(err,data) {
if (data && data.length === text.length) {
res.send("OK at length " + text.length + " " +data.length);
} else {
res.send("Failed at " + text.length + " " );
}
});
})
} catch(e) {
res.send("Failed at " + text.length + " " + e.message);
}});
