request to replace deprecated `system-fileio` with `directory`

[peterbecich]

Hello, I am attempting to build http-io-streams with Nix. Specifically, hackage-server depends on http-io-streams, and I'm attempting to update the Nix build of hackage-server: haskell/hackage-server#1283

I am having difficulty with http-io-stream's dependency on deprecated package https://hackage.haskell.org/package/system-fileio

Can this be replaced with https://hackage.haskell.org/package/directory ?

Thank you

system-fileio

Can this be replaced with hackage.haskell.org/package/directory ?

Well, yes it can, but someone has to do it, and there is a risk of regressions, like it happened for shelly:

• Drop depedency system-fileio and system-filepath gregwebs/Shelly.hs#182
• upgrade to 1.9 breaks our test suite gregwebs/Shelly.hs#189
