uploading the same file should be faster

[ajeecai]

As far as I know about tus, the client should check if the same file has been uploaded before. if so the upload progress should be fasten and reach 100% in one second.

Here is my observation while running up this demo by "npm start" and uploading the same file several times:

1. The second uploading is just as a normal uploading, the progress starting from 0% .... to 100% at a normal pace. Check the server side, the file uploaded in last time remains the same size , not truncated to a smaller one. Finally its timestamp is updated.
2. During the second uploading, I make it offline by using chrome dev tool, the uploading turns into "paused", then I turn it back to "No throttling", the progress go directly to 100%, as sudden as lightning.

Thanks

@ajeecai This is controlled by the server:

• uploadx not overwrite completed files
• tus always overwrite completed files

Other tus servers usually create a new file. Incomplete files are not overwritten, of course.

I'll try to make it more consistent.

Thank you @kukhariev, it looks better if we don't overwrite the completed files since that will demo resumable (Just curious, tell if the same file by only filenames or hash value? I don't read all of the code for now),

Thank you, could you also publish this update so that I could get it from npmjs?

Thanks
