Probable bug when piped into Hash #54
Open
Description
fstream_hash_issue_example.js
computes MD5 hash of a file read from filesystem.
Program call and output in cmd.exe, Windows :
F:\...>node fstream_hash_issue_example.js
fs.createReadStream: dd9e30aa94c1074d863846c4ed35b8bd
fstream.Reader: d41d8cd98f00b204e9800998ecf8427e
fstream.Reader: dd9e30aa94c1074d863846c4ed35b8bd
The code:
var crypto = require('crypto'),
fs = require('fs'),
fstream = require('fstream'),
through = require('through2');
function getHasher(tag){
var md5Hasher = crypto.createHash('md5', { encoding: 'hex' });
md5Hasher.on('readable', () => {
var data = md5Hasher.read();
if (data)
console.log(
tag+data
);
});
return md5Hasher;
}
fs.createReadStream("program.js").pipe(getHasher('fs.createReadStream: '));
fstream.Reader("program.js").pipe(getHasher('fstream.Reader: '));
fstream.Reader("program.js").pipe(through(
//No-op stream
function(buf,_,next){
this.push(buf);
next();
}
)).pipe(getHasher('fstream.Reader: '));
Environment:
Windows 10 Pro,
node v.4.2.4,
fstream 1.0.10
