preservePath option not respected

[cwkang1998]

Currently, when passing preservePath as an option to multer, it seems that its not respected and the path were not preserved.

The input provided is in the format Buffer, passed like so in the test file using supertest:

const reqInstance = testApp.post(
 /upload-multiple
);

// Add files
codeFiles.forEach((file) => {
  reqInstance.attach(
    `files`,
    file.data, // buffer,
    {filename:  `/some/path/${file.name}.txt` }
  );
});

const response = await reqInstance
  .set("Content-Type", "multipart/form-data")
  .expect(200)

The server is setup like so:

const app = express();
const upload = multer({ storage: memoryStorage(), preservePath: true });

app.post("/upload-multiple", upload.array("files"), (res) => {
   console.log(res.files[0].originalname) // here it shows only {file.name}.txt, not the full path.
   return "OK"
})

Have not tried to replicate this using busboy yet, will do so if I manage to find time for the replication.

Is this behaviour expected?

I believe 2.0.0-rc.4 adds code to pass this option to busboy. If you need something now, you can try that version with npm install [email protected].

@joeyguerra Let me try it, if it works as expected then this shouldn't be an issue.
