Wrong content-length header for datasets #261

Open fdietze opened 2 months ago

fdietze commented 2 months ago

Describe the bug When downloading the datasets from https://x.com/i/communitynotes/download-data using wget, it hangs, not receiving more data, because the content-length header is too big (566M) for the file being served (185M).

To Reproduce

wget https://ton.twimg.com/birdwatch-public-data/2024/09/07/notes/notes-00000.tsv
wget https://ton.twimg.com/birdwatch-public-data/2024/09/07/notes/notes-00000.tsv
--2024-09-07 13:43:04--  https://ton.twimg.com/birdwatch-public-data/2024/09/07/notes/notes-00000.tsv
Resolving ton.twimg.com (ton.twimg.com)... 2606:2800:233:7ee2:97c:ab4c:6c70:be36, 152.199.21.140

notes-00000.tsv         32%[=======>                   ] 185.19M  --.-KB/s    eta 2m 58s

Expected behavior The content-length header should be set to the file size.

~Same thing, in Safari and wget, today, with https://ton.twimg.com/birdwatch-public-data/2024/09/21/notes/notes-00000.tsv

(BUT, at least wget does sort-of-work/fail gracefully, eventually:
