Unable to install cabal-install-3.8.0.20220526 on Windows

[cydparser]

Describe the bug

ghcup fails to install the prerelease version of cabal-install. The error indicates that a file named cabal.exe was not found. The zip file contains a file named cabal (without an extension).

To Reproduce

ghcup config add-release-channel https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.7.yaml
ghcup install cabal 3.8.0.20220526 

Resulted in:

Error: (Unable to copy a file. Reason was: C:\Users\cyd\AppData\Local\Temp\ghcup-c840ea7fe45060fc\cabal.exe: copyFile:atomicCopyFileContents:withReplacementFile:copyFileToHandle:openBinaryFile: does not exist (No such file or directory),
 The version 3.8.0.20220526 of the tool cabal is not installed.)

System information

• Windows 11
• GHCup v0.1.17.8-p1

This an unfortunate but known oversight, see #8191. Should be fixed in the future (pre)releases. I'm not sure though why this pre-release hasn't been fixed.

Correct.

I'm not sure though why this pre-release hasn't been fixed.

I'm guessing, we didn't want to break the checksums? Not sure.

@hasufell: is there a non-dirty way of working around that problem in ghcup (by the user or by us)?

We you fix the bindist manually and upload it as -p1 as a new tarball.

[Mikolaj]

I do that (with a new signed file containing the new single checksum?) and what happens next? How does that help?

You upload it?

[Mikolaj]

OK, I fix, name with suffix -p1, checksum, sign, upload to the same directory as the previous 3.8.0.20220526 archives. Correct? Then what? I'd like to understand, so that I don't make wrong assumptions and silly mistakes.

Then you wait for me to get sober and update ghcup metadata.

Done. (CDN may take some hours.)

Then you wait for me to get sober and update ghcup metadata.

How do we catch that short window of opportunity?

@hasufell: respectful ping?

[hasufell]

Ping me tomorrow again 🍻

[Mikolaj]

Good times! :D
