Commit af5441dcd9 has caused a
regression ( https://github.com/rfjakob/gocryptfs/issues/35 )
that is fixed by this commit.
The go-fuse library by now has all the syscall wrappers in
place to correctly handle Utimens, also for symlinks.
Instead of duplicating the effort here just call into go-fuse.
Closes#35
This fixes a build problem on 32-bit hosts:
internal/fusefrontend/file.go:400: cannot use a.Unix() (type int64) as
type int32 in assignment
internal/fusefrontend/file.go:406: cannot use m.Unix() (type int64) as
type int32 in assignment
It also enables full nanosecond timestamps for dates
after 1970.
This should make it work on OSX.
Also, split unmount into two functions. Depending on what you
want,
* UnmountErr returns the resulting error
* UnmountPanic panics if the error was not nil
"go tool vet -shadow=true" complained about the md5 package
being shadowed by variables called "md5".
Fix by using the Md5hex helper and dropping the md5 import.

warning: indirection of non-volatile null pointer will

...and convert all calls to syscall.{Fallocate,Openat}
to syscallcompat .
Both syscalls are not available on OSX. We emulate Openat and just
return EOPNOTSUPP for Fallocate.
unPad16 returns detailed errors including the position of the
incorrect bytes. Kill a possible padding oracle by lumping
everything into a generic error.
The detailed error is only logged if debug is active.
We were growing the file block-by-block which was pretty
inefficient. We now coalesce all the grows into a single
Ftruncate. Also simplifies the code!
Simplistic benchmark: Before:
$ time truncate -s 1000M foo
real 0m0.568s
After:
$ time truncate -s 1000M foo
real 0m0.205s
XFS returns a different error code if you try to overwrite
a non-empty directory with a directory:
XFS: mv: cannot move ‘foo’ to ‘bar/foo’: File exists
ext4: mv: cannot move 'foo' to 'bar/foo': Directory not empty
So have EEXIST trigger the Rmdir logic as well.
Fixes issue #20
Link: https://github.com/rfjakob/gocryptfs/issues/20
...and add tests for checking that gocryptfs.diriv
does not get created.
The main "integration_tests" package has become quite
big and convoluted over time.
This small separate package should make writing tests
for "-plaintextnames" easier.
As seen in "fusefrontend: fix PlaintextNames versions of Mkdir, Rmdir",
we need more of them.
Drop the date and add the "go-fuse: " prefix so you can see
where the message is coming from.
