* add an overall timeout value for tests - if running longer,
testbench framework tries to FAIL and end test. Note that
this is not bullet-proof and not intended to be so.
* guard against hanging rsyslog instances via a new imdiag
feature to abort after n number of seconds; among others,
this guards as against timeout-cancel in CI, which is always
pretty hard to diagnose - now we see these errors in test-suite.log
* fix a bug in tcp zip test, which actually did not use zip mode
* experimnentalls add debug output to better understand
shutdown_when_empty operation; goal is to improve understanding
and then remove that code again.
* improve shutdown predicate for a couple of tests
* made travis run make check with two parallel threads, for which
we seem ready now. Nevertheless, it's still experimental and we
may roll this back if required.
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
changes some of the test commands to use bash functions
includes some small bug fixes to tests where bugs were
previously not seen due to different plumbing.
- Don't use $UID, use $EUID instead
- Allow user to specify testuser (through RSYSLOG_TESTUSER env variable)
or fall back to various default users
- Validate if user running tests can really impersonate another user
- Test if testuser really exists
