Fails xfstests generic/013, renames files to ".deleted"

If something shows up in directory listings, then you must have somehow got these into the OpenDir() result.

can you post the stack trace for the NPE ?

Sorry, my description was unclear: The files show up under their normal name, but gocryptfs gets passed ".deleted" on any operation, hence stat and everything else fails. Will post the NPE sunday evening!

I cannot reproduce the NPE with a fresh checkout of go-fuse. Must have been caused by my debug code.

On the plus side, I can reproduce this with the loopback example (with ClientInodes enabled, patch: rfjakob@1f50fb4 , otherwise no changes)

$ ( set -e; while true; do ~/src/fuse-xfstests/ltp/fsstress -p 1 -z -f rmdir=10 -f link=10 -f creat=10 -f mkdir=10 -f rename=30 -f stat=30 -f unlink=30 -f truncate=20 -m 8 -n 1000 -d /tmp/b; rm -R /tmp/b/*; sleep 1; done )
seed = 1456229227
rm: cannot remove ‘/tmp/b/p0/d9/d2c/d6c/dbc/d130/d12d/d156/d15a/d13b/f162’: No such file or directory
rm: cannot remove ‘/tmp/b/p0/d9/d2c/d6c/dbc/d130/d12d/d156/d15a/d13b’: Directory not empty

By the way, fsstress is the one included in xfstests, you can clone it from https://github.com/rfjakob/fuse-xfstests/tree/gocryptfs/ltp .

Found a single-shot reproducer that works every time. Note that the "sleep 1" in the middle is essential and the test comes back clean without it.

~/src/fuse-xfstests/ltp/fsstress -p 1 -z -f rmdir=10 -f link=10 -f creat=10 -f mkdir=10 -f rename=30 -f stat=30 -f unlink=30 -f truncate=20 -m 8 -n 1000 -d /tmp/b -s 1456162204 ; sleep 1; rm -Rf /tmp/b/*
