The difference between the old and new files is the name of the enclosing directory, which used to be oiio-2.1.20.0 and is now OpenImageIO-2.1.20.0. This problem was caused by [41c2d0da6bcc085d8bd4be8e1086ac87e27d9c3b/macports-ports].

openimageio: fix checksums

Fixes: #69775

[ryandesign (Ryan Carsten Schmidt)]

But you can't just change the checksums when you change the contents of a distfile. This is a stealth update.

[mohd-akram (Mohamed Akram)]

I think it was a stealth update before my PR. Since the PR changed the name of the GitHub project from oiio to OpenImageIO, the name of the distfile also changed.

Replying to mohd-akram:

I think it was a stealth update before my PR.

Ah you're right. Upstream changing the name of their repository is what caused the enclosing directory name to be changed. The archive value of github.tarball_from insulates us against developers moving their repository to a different GitHub developer name but does not insulate us from repository name changes. The only insulation from that would be if upstream provided their own release tarballs. Unfortunately, openimageio doesn't. I've suggested they do so in the upstream issue: ​https://github.com/AcademySoftwareFoundation/OpenImageIO/issues/4003

Since the PR changed the name of the GitHub project from oiio to OpenImageIO, the name of the distfile also changed.

Right again. I misremembered the default distfile name of the github portgroup. I thought it was based on the port name, but it is indeed based on the GitHub project name.

My apologies. I need more coffee.
