Brennan Kinney a7e6439a39 fix: Workaround postconf write settling logic (#2998) ... * fix: Workaround `postconf` write settle logic After updating `main.cf`, to avoid an enforced delay from reading the config by postfix tools, we can ensure the modified time is at least 2 seconds in the past as a workaround. This should be ok with our usage AFAIK. Shaves off 2+ seconds roughly off each container startup, reduces roughly 2+ minutes off tests. * chore: Only modify `mtime` if less than 2 seconds ago - Slight improvement by avoiding unnecessary writes with a conditional check on the util method. - Can more comfortably call this during `postfix reload` in the change detection cycle now. - Identified other tests that'd benefit from this, created a helper method to call instead of copy/paste. - The `setup email restrict` command also did a modification and reload. Added util method here too. * tests(fix): `mail_smtponly.bats` should wait for Postfix - `postfix reload` fails if the service is not ready yet. - `service postfix reload` and `/etc/init.d/postfix reload` presumably wait until it is ready? (as these work regardless) * chore: Review feedback - Move reload method into utilities		2023-01-13 10:10:58 +13:00
