# Travis doesn't provide FreeBSD machines, so we just take a Linux one and run
|
|
# FreeBSD in qemu virtual machine. qemu is being ran in curses mode inside a
|
|
# screen session, because screen allows to easily send input and read output.
|
|
# The input is sent using `screen -S session-name -X stuff ...` and the output
|
|
# is read from the screen's log file. Note that for some reason you can't send
|
|
# long input lines on Travis (it works just fine when I do it on my machine...),
|
|
# but that limitation is not an issue, as we don't really need to send long
|
|
# lines of input anyway. Also, note that since we run qemu in curses mode, the
|
|
# output contains control characters intended for a terminal emulator telling
|
|
# how to position and color the text, so it might be a little tricky to read it
|
|
# sometimes. The only time when this script has to send input to and read the
|
|
# output from the screen session is during the initial setup when we setup the
|
|
# network, install and configure the ssh server, and update the system. After
|
|
# this initial setup, ssh is used to communicate with the FreeBSD running in the
|
|
# VM, which is a lot friendlier way of communication. Please note that Travis
|
|
# doesn't seem to allow KVM passthrough, so qemu has to emulate all the
|
|
# hardware, which makes it quite slow compared to the host machine. We cache
|
|
# the qemu image since it takes a long time to run the initial system and
|
|
# package updates, and we do incremental system and package updates on every
|
|
# change to the list of git tags (i.e. on every toxcore release, presumably).
