sha filename length breaking on ext4 filesystem

when running “git clone” on a recent version of paraview: “error: unable to create file Clients/ParaView/Testing/Data/Baseline/.ExternalData_SHA512_666010fefb7a8a9f3d15a5d7cba039033490b583eaed34bdd852cf989f836f07104f050c2e6be9d8467a45cab066c08f78cdf499681436098f6a09fb3dfbd567: File name too long”
I’m guessing this is hitting the character limit on ext4. Is this a bug? Any workaround? ubuntu20.04.

These files should not even be there. Ill fix that.

Will be fixed once this is merged:
