File not fully uploaded

[ajouve]

Hi,

I am trying to upload a file of 116MB into a local ftp server.

const FTP = require('ftp');
const fs = require('fs')
const config = require('./config')

const ftp = new FTP();

const buffer = fs.readFileSync('/Users/ajouve/Downloads/test.bin')

ftp.once('ready', () => {
    console.log('connected');
    ftp.put(buffer, 'SD_Card/test1.bin', (err) => {
        console.log(err);
        console.log('done')
    })
});

ftp.connect({ host: config.fan.ip, user: 'admin', password: 'admin' });

The put ends with no error but when I am checking the size on the ftp the file is not fully uploaded.

The logic is a little random, with the script I just set earlier it will upload between 80% and 100%, but this was just a script to debug. The normal script is doing heavy processing on the bin file generation and in this case the upload is between 5% and 10%

I tried to add a function to cut my buffer

/**
 * 
 * @param {Buffer} buffer 
 * @param {number} splitSize 
 */
module.exports.splitBuffer = (buffer, splitSize) => {
    let i = 0;
    const bufferSize = buffer.byteLength;
    const buffers = [];
    while(i < bufferSize) {
        const start = i;
        const end = i + splitSize > bufferSize ? bufferSize : i + splitSize;
        buffers.push(buffer.slice(start, end));
        i = end;
    }

    return buffers
}

and then upload it using put for the first element and then append but my ftp server does not support append

Append/Restart not permitted, try again

did you ever resolve this? I get no errors while uploading but checking my ftp server it's not there

I change the FTP lib :D
