Issue 39488: test_largefile: TestSocketSendfile.test_it() uses too much disk space (original) (raw)

TestSocketSendfile.test_it() failed with "OSError: [Errno 28] No space left on device" on PPC64LE Fedora 3.x buildbot.

It also caused troubles on "AMD64 Fedora Rawhide Clang 3.x" worker.

If I recall correctly, it writes like 8 GB of real data, not just empty files made of holes.

I suggest to either remove the test or to use way less disk space.
