• 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
• We c
