GHA: remove ._ files from macOS zip

[metayan]

To get rid of these errors when starting scsynth:

*** ERROR: dlopen '[...]/Extensions/sc3-plugins/SC3plugins/AYUGens/._AY_UGen.scx'
err 'dlopen([...]/Extensions/sc3-plugins/SC3plugins/AYUGens/._AY_UGen.scx, 2): no suitable image found.
Did find: [...]/Extensions/sc3-plugins/SC3plugins/AYUGens/._AY_UGen.scx: file too short

Thx for the PR. But isn't the existence of these files a hint to a faulty CMake file or why are they there in the first place?

[metayan]

I suspect the zip program that is used on the build machine.
Maybe in combination with the filesystem.
Wouldn't suspect cmake.

I haven't been able to replicate the generation of the '._' files on a real macOS Catalina.
It seems that either the zip used here is different or the filesystem behaves differently than on the system where the releases are built.

By the way, I tried to test the fix on GitHub by activating Actions, and everything got built except the macOS version, because the macOS runner refused to start.

I tried downloading the 3.13.0 release zip, unpacked it in my Downloads folder and I don't see any hidden files:

% ls -al sc3-plugins/SC3plugins/AYUGens

I.e. I don't see the issue that you're reporting.

Also, IF the issue indeed happens, a better solution would be to not include hidden files in the zip in the first place, instead of removing them afterwards.

BTW we probably need to update the macOS runner in GHA since macos-11 image has been removed and that's why macOS jobs don't run anymore.

It seems that the ._* files are created by macOS on a non-macOS filesystem to store some Apple-specific attributes. I'm guessing that the releases are built on a non-macOS filesystem.

Anyway, trying to exclude the ._* files with
zip -r pack.zip sc3-plugins -x ._\*
should work, but doesn't.

tar jcvf pack.tar.bz2 --exclude ._\* sc3-plugins
correctly excludes the ._* files, so switching to tar for the macOS version is a solution, and since macOS is sort of UNIXy, it's quite appropriate. ;)

Tip:

If unpacking using unzip, running

dot_clean sc3-plugins

afterwards cleans out the ._* files.

[metayan]

Newer macOS runner doesn't include the ._* files - as demonstrated in #380.
Closing.

Thanks for the update.
FWIW on my system when testing the 3.13 release zip, when I unzip the file by double clicking it in Finder, the dot files are not included in the resulting folder. When I unpack it using the unzip command, then indeed I can see the dot files.
