Uploading the same file with same name overwrites old file

[safaorhan]

I uploaded a file name host.jpg for the first time. It saved the file into the folder /public/upload.

The response of calling GET /upload is fine:

[{ "filename": "host.jpg", "filesize": 35706, "creationDate": 1467561753773, "uploaderId": "26c2828d6d9d08a5", "type": "image/jpeg", "id": "370fc11a74c8aa8b" }]

After uploading the same file again (I think) it overwrites the file. There is just one file under /public/upload folder and calling GET /upload shows multiple entries:

[{ "filename": "host.jpg", "filesize": 35706, "creationDate": 1467561753773, "uploaderId": "26c2828d6d9d08a5", "type": "image/jpeg", "id": "370fc11a74c8aa8b" }, { "filename": "host.jpg", "filesize": 35706, "creationDate": 1467561950163, "uploaderId": "26c2828d6d9d08a5", "type": "image/jpeg", "id": "80e90364f3528877" }]

Is it the expected behavior?

3 years from now and having same problem, i just changed the md5 line that rename the files to this:
Date().now() // seems buggy
file.name = md5(new Date().getFullYear() + new Date().getSeconds() + file.name + new Date().getMonth() + new Date().getMinutes() ) + '.' + file.name.split('.').pop();

it worth it to take few minutes read plugin and write your own since this lib using formidable..
