crates under 3/l downloaded incorrectly

[Kepler-Br]

% cargo install cargo-cache
    Updating `panamax` index
  Installing cargo-cache v0.8.3
error: failed to compile `cargo-cache v0.8.3`, intermediate artifacts can be found at `/tmp/cargo-installGZoqCc`

Caused by:
  failed to download from `http://crates.dw/3/l/log/0.4.17/log-0.4.17.crate`

Caused by:
  failed to get 200 response from `http://crates.dw/3/l/log/0.4.17/log-0.4.17.crate`, got 404

I've checked index and there is an index file under /3/l/log, but crates folder contains log crate under path 3/log which is not correct

I've tried with dockerized version of latest commit on master

You can't serve the files directly without some rewrites, see the sample nginx config in the repo: https://github.com/panamax-rs/panamax/blob/master/nginx.sample.conf

I'm not sure why the decision was made to have the on-disk layout differ from the served layout. I wanted to use panamax to update a mirror which is mounted into build tasks (so the crates base URL is a file:// URL) but it doesn't work because of this same issue.

Oh shoot, I didn't realize the formats differed - the intention was to have them be the same format. I could've sworn the index used to be 3/(crate) rather than 3/(1st letter) /(crate).

Ill try to get this fixed - sorry about that.

Actually even with the rewrites in place, there seem to be issues with crates that have short names.

[16/Jan/2023:05:40:15 +0000] "GET /crates/3/n/num/0.3.1/num-0.3.1.crate HTTP/1.1" 404 153 "-" "cargo 1.66.1 (ad779e08b 2023-01-10)"

I replaced the rewrites with this and it seems to work:

rewrite "^/crates/3/[^/]/([^/]+)/([^/]+)/([^/]+)$" "/crates/3/$1/$2/$3";

The other rewrites, so far, seem unnecessary. Maybe needed for an older cargo version?

This should be fixed as of 1.0.8. Feel free to reopen this issue if you're still having trouble.
