404 with ghcup install ghc 9.8.1-alpha1

[minoki]

The URL in metadata seems to be wrong: metadata says https://downloads.haskell.org/~ghc/9.8.0.20230727/ but the correct URL is https://downloads.haskell.org/~ghc/9.8.1-alpha1/.

Thanks; now fixed!

[phadej]

@bgamari how is this fixed? the metadata is still the same, and https://downloads.haskell.org/~ghc/9.8.0.20230727/ returns 404

[phadej]

Note: https://downloads.haskell.org/~ghc/9.8.0.20230727/ with tilde is 404, https://downloads.haskell.org/ghc/9.8.0.20230727/ without tilde works.

Note: https://downloads.haskell.org/~ghc/9.8.0.20230727/ with tilde is 404, https://downloads.haskell.org/ghc/9.8.0.20230727/ without tilde works.

Now these two seem to point to the same directory.

[phadej]

and also in Firefox (which I never use, so it's not my cache). But curl from console seems to get the directory listing.

Is some cache somewhere too aggressive?

[phadej]

which is different from curls:

x-served-by: cache-dfw-kdfw8210105-DFW, cache-hel1410023-HEL
x-cache: HIT, HIT
x-cache-hits: 1, 1
x-timer: S1690885563.566476,VS0,VE5

so I guess the cache is too aggressive.

EDIT: That is not good, as a nasty person could just poll https://downloads.haskell.org/~ghc/9.8.1/ and https://downloads.haskell.org/ghc/9.8.1/ to annoy other people, if caches are not purged when new directory/files are addded
