Potential Content-Length miscalculation

[jjg]

When a HEAD request is made for a file, I noticed a discrepancy between the Content-Length and the X-Media-Size headers of 8 bytes. X-Media-Size comes from inspection of the uploaded file's internal structure whereas Content-Length is calculated as the file is uploaded.

Line 296 in server.js:

this.file_metadata.file_size = this.file_metadata.file_size + this.input_buffer.length;

I'm wondering if the line above is "padding" the end of the stored file by including empty buffer?
