set maxFilesSize can't response error

[youxiachai]

I found if set

var express = require('express'),
    multipart = require('connect-multiparty'),
    multipartMiddleware = multipart({
        maxFilesSize : 2 * 1024
    })
    http = require('http');

var app = express()

app.set('port', 5000);
app.get('/', function (req, res) {
    res.send('<form method="post" enctype="multipart/form-data">'
        + '<p>Title: <input type="text" name="title" /></p>'
        + '<p>Image: <input type="file" name="image" /></p>'
        + '<p><input type="submit" value="Upload" /></p>'
        + '</form>');
});

app.post('/', multipartMiddleware, function (req, res) {
    res.send('ok');
});

app.use(function (err, req, res, next){
    console.log('handle error')
    console.error(err.stack);
    res.send(500, 'Something broke!');
})


http.createServer(app).listen(app.get('port'), function () {
    console.log('env: ' + process.env.NODE_ENV);
    console.log('Express server listening on port ' + app.get('port'));
});

if I upload more than 1 MB(but work ~40KB) size file ,It will throw err in console, but it will not send response !!

so browser will hang request !!

I added a test for this, but the test passes. Can you provide a test case that demonstrates your problem?

[youxiachai]

if file small ，it will work well，but large file will hang request，although it throw error

How to fix?

We need someone (perhaps you?) to give us a patch that fixes the issue, or a single complete JS file we can run and hit the issue so we can investigate. So far no one has offered us either of those.

var express = require('express');
var app = express();
app.set('port', 3000);

var serveStatic = require('serve-static');
app.use(serveStatic('./public', {'index': ['default.html', 'default.htm']}));

var multiparty = require('connect-multiparty');
app.post("/upload",
    multiparty({
        uploadDir:"./tmp",
        maxFilesSize:1 * 1024 * 1024
    }),
    function(req,res){
        res.end("ok..");
    }
);
var http = require('http');
http.createServer(app).listen(app.get('port'), function () {
    console.log('Express server listening on port ' + app.get('port'));
});

OK,Thanks.

[Douglas Wilson]

@285858315 did it work? Any verdict yet?

[Douglas Wilson]

Please try version 1.0.4 of this module.

[youxiachai]

@dougwilson I test 1.0.4 it work well (limit 2M upload file 100M, not hang request)! thanks fix this bug!

[Douglas Wilson]

@youxiachai thank you for confirming this does seems to fix the issue :)

[Yang Yu]

@dougwilson I am still having this issue in v3.3

using form.on 'file',
and form.on 'error'

something I missed?

currently I'm doing this, but not sure if it's efficient.

form.on 'file', (name, file) -> 
  if file.size > conf.app.upload_size
    return ex.throw new ex.Validation('file is too large'), res

Hi @mryangyu it's possible it's not the same issue as here. Can you open up a new issue in the repo? I'll be happy to help. If you have any more code to share that would also be helpful :)

If you are talking about events, I think you meant to file the issue in this repo, actually: https://github.com/andrewrk/node-multiparty

Update: I see the code you put and it's probably not correct; I would need to see more, though, but just in a new issue, please :)
