For some unknown reason mac takes offence to searching for
'test_dir_unicode'. 'test_dir_hidden' seems to work fine.
This isn't a proper fix as I've just hacked round the problem. Ideally
I'd need a mac user to do some investigation.
Because apparent_size uses the test files created in /tmp it needs to be
in the test_exact_output where those files are copied. Otherwise the files
may not be there when the test is run.
-t = Show summary of types
-e = Filter by regex
allows you to specify a file type like -e "\.txt$"
Change behaviour of '-f' flag - it now counts only files. Before it
counted files & directories. This was needed for compatibility with
the new '-e' filter flag
Move apparent size test to 'test_flags' file. We can no longer test the
exact output of this test as it changes too much on different filesystems
Move common code to shared initialization function in test_flags.rs
Code changes:
Removed ignore & channel crates. Using a single reciever thread to build
a hashmap to prevend duplicate inodes being reported gave a severe
performance penalty
Using rayon crate with some hand crafted file traversal has improved
performance aprox 10X
Behaviour changes:
Removed parameter 'limit by filesystem' - don't think this is used, and
I only added it as it was easy to add with the ignore crate.
Sym links will now not appear in the output tree unless using '-s'
'apparent-size' flag
Change behaviour of multiple args so that it unifies them and
compares them under one tree instead of treating them
individually: https://github.com/bootandy/dust/issues/136
