r278742:
Simplify jail_name_to_jid and try to be more fault tolerant when scanning for
the jail ID (poll up to 10 times for the jail IDs to become available)
If the scan fails, the code will fall through and fail as it does with Jenkins
today
r278636:
Parameterize out the amount of sleep done in each test
Set the value in each test to a different amount to avoid potential
side-effects with other instances of the test (or lingering processes) still
being present on the system
r278633:
Refactor the tests
1. `id -u` -> 0 is now only checked once; the entire test script is now skipped
if this assertion is violated
2. De-dent whitespace, based on 1.
3. Only setup the symlink for $sleep once at the top of the script, and tear it
down once at the bottom of the script
- use daemon(8) to write out a pid file for processes,
and check for for the existence of that file after
killing processes
- use explict named parameters to jail(8)
Interestingly, the pkill tool lives in bin, not usr.bin. Haven't bothered
to check if this is because the tool moved or because the tests were
originally added in the wrong place.
