Chasing a bug that seems to have nothing to do
with magic names, as it already triggers during
warmup:
--- FAIL: TestMagicNames (0.00s)
matrix_test.go:773: Testing n="warmup1"
matrix_test.go:773: Testing n="warmup2"
matrix_test.go:820: no such file or directory
Simplify the tests by using empty files. Empty
files are valid, and we don't check the content
anyway.
Also adjust comment style a little and add
a missing break statement.
Changed invalid file decoding and decryption. Function
DecryptName now shortens the filename until the filename is
decodable and decryptable. Will work with valid **and**
invalid Base64URL delimiter (valid delimiter [0-9a-zA-z_\\-].
If the filename is not decryptable at all, it returns the
original cipher name with flag suffix Changed cli tests to
generate decryptable and undecryptable file names with correct
encrypted content. Replacing #474, extends #393
Locale trouble was
sshfs-benchmark.bash: line 31: printf: 4.71: invalid number
because printf expected "4,71" in the German locale.
Force the C locale.
Looking at the dircache debug output, we see
that a "git status" workload has a very bad
cache hit rate because the entries expire or
get evicted before they can be reused.
Increase both cache size and lifetime for
a 4x speedup:
Before: 75s
After: 17s

Move the statusTxtContent to fix this confusing error
when running `go get github.com/rfjakob/gocryptfs/...`:
$ go get github.com/rfjakob/gocryptfs/...
# github.com/rfjakob/gocryptfs/tests/example_filesystems
tests/example_filesystems/example_test_helpers.go:22:16: undefined: statusTxtContent
tests/example_filesystems/example_test_helpers.go:75:16: undefined: statusTxtContent
On Fedora, /tmp is tmpfs, which behaves differently than ext4
(inode numbers are never reused, for example).
Use /var/tmp, which is ext4 on Fedora, to get a more realistic
test environment.
This also allows us to drop the xattr workaround.
When running
$ go test ./tests/matrix/
in isolation, it failed like this:
fd leak? before, after:
[0r=/dev/null 3w=/dev/null 5r=/proc/8078/fd (hidden:4)]
[0r=/dev/null 3w=/dev/null 5w=/tmp/go-build366655199/b001/testlog.txt 7r=/proc/8078/fd (hidden:4)]
Filter by prefix to get rid of this spurious test failure.
When we run tests as root, they will leave root-owned files
in testParentDir, which causes trouble when we run tests as
a normal user later on. Split by UID.
CheckTrailingGarbage was called even when "-passfile" was
used, which is stupid, and causes false positives:
https://github.com/rfjakob/gocryptfs/issues/391
(false error "Received trailing garbage after the password"
when using -passfile in .bash_profile)
Instead of trying to improve the logic to handle that case
and make everything even more complicated, delete the function.
It is unclear if actually helps in some cases, and it definitely
harms as shown by the above bug report.
