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.
This adds support for gitignore-like wildcards and exclude patters in
reverse mode. It (somewhat) fixes#273: no regexp support, but the
syntax should be powerful enough to satisfy most needs.
Also, since adding a lot of --exclude options can be tedious, it adds
the --exclude-from option to read patterns from a file (or files).
Ironically, the test for DirIV races had a data race itself
by writing to a bool without taking a lock.
