# Allows the following environment variables
# TRAVIS_RUN=[true|false]
# SSH_PORT=22
# SKIP_REMOTE=[true|false]

## On Mac OSX, this needs to be run as root in order to use sudo without password
## From current terminal run sudo -s in order to get a new terminal as root

## On CYGWIN / MSYS, ACL and extended attributes aren't supported

# 4 tests:
# quicklocal
# quickremote (with ssh_filter.sh)
# conflocal
# confremote (with ssh_filter.sh)

# for each test
# 	files with spaces, subdirs
# 	largefileset (...large ?)
#	quickremote test with controlmaster enabled
# 	exclusions
# 	conflict resolution initiator with backups / multiple backups
# 	conflict resolution target with backups / multiple backups
# 	deletion propagation, failed deletion repropagation, skip deletion
#	symlink and broken symlink propagation and deletion
# 	replica lock checks
#	file attribute tests
# 	local / remote locking resume tests
#	conflict detection
#	timed execution tests

# function test
# WaitForTaskCompletion
# ParallelExec
# daemon mode tests for both config files

# on BSD, remount UFS with ACL support using mount -o acls /
# setfacl needs double ':' to be compatible with both linux and BSD
# setfacl -m o::rwx file

# On Windows 10 bash, we need to create host SSH keys first with ssh-keygen -A
# Then start ssh with service ssh start

# TODO, use copies of config file on each test function
