Writing Keys from .NET SDK , not able to READ from node js within clustered enviroment

[Himanshu44ec06]

I am writing my Keys from .NET SDK and reading it from NODE JS and my environment is clustered , it was giving me undefined when reading KEY

@Himanshu44ec06 Could you please provide more detail:

Which .NET SDK do you use, is reading from .NET SDK normal? What's the type of the value?

A Minimal reproducible example could help me a lot.

Check if you have CR LF in your data, it causes bugs

#~/memcacheTest# cat test.sh
npm install memcached
echo -n "set keyWithCrLfCrLf 0 0 4\r\n\r\n\r\n\r\n" | nc 127.0.0.1 11211
date
node memcachedtestFAIL.js
date
echo FINISHED
#~/memcacheTest# cat memcachedtestFAIL.js 
const memcached = require('memcached');
const server = new memcached('127.0.0.1:11211', {debug:1});

console.log('START DATA READ');
server.get('keyWithCrLfCrLf', (err, data) => {
        if (err) {
                console.log(err);
        } else {
                console.log('Data received', data);
        }
        process.exit();
});

Callback is never called. No data, even no error, it just freezes in case when you have string containing CR-LF sequences.

Looks like it's fixed in https://github.com/3rd-Eden/memcached/pull/295/files

@drull755 , Thanks a lot for digging in. This is definitely a bug and should be fixed.

But I'm not sure that the problem @Himanshu44ec06 encountered is the same one. Could you provide an example of the VALUE?
