For completness of this thread, here is the 0.8 code I am now using to get
this right:
var callbackHandled = false;
var readStream = fs.createReadStream(source);
var writeStream = fs.createWriteStream(target);
var onError = function(error:Error) {
if (!callbackHandled) {
callbackHandled = true;
callback(error);
}
};
readStream.on('error', onError);
writeStream.on('error', onError);
readStream.on('end', function() {
writeStream.end(function() {
if (!callbackHandled) {
callbackHandled = true;
callback(null);
}
});
});
readStream.pipe(writeStream, {end: false});
