  • We want to provide good quality progress meters at console for fetch+unpack operation
  • Measuring progress smoothly requires knowing not just how many compressed bytes you have read but how many decompressed bytes you have written
  • Knowing the percentage complete of decompressed bytes written requires knowing the total decompressed size
  • Knowing the total decompressed size requires reading the field of the gzip layout that indicates decompressed size
  • That field is at a fixed offset from the end of the gzip file
  • In order to still get benefit of streaming we have to make a separate HTTP HEAD request to find the content length of the file and then a subsequent GET request to fetch just that tiny byte range to read that one field
  • (This does have overhead of a couple extra HTTP requests — anecdotally this seems cheap enough not to matter but maybe could matter in some environments?)
  • Unfortunately for GitHub releases, the files redirect to S3 URLs which seem to reject HEAD requests with a 403
