Also now permit interactivly running tests without explicitly setting $srcdir. This now works if we are inside ./tests and fails, as before, when we are in a different directory. Detected by shellcheck via CodeFactor.io

# This tests checks for a anomaly we have seen in practice:
|
|
# gethostname() may return an empty string as hostname (""). This broke
|
|
# some versions of rsyslog, newer ones return "localhost" in that case.
|
|
# The test is done with the help of a preload library specifically written
|
|
# for this purpose (liboverride_gethostname.so). It will override
|
|
# gethostname() and return an empty string. Then, the test checks if the
|
|
# hardcoded default of "localhost-empty-hostname" is used.
|
|
# Note that the test may fail if the library is not properly preloaded.
|
|
# This is part of the rsyslog testbench, licensed under ASL 2.0
