auto: Automatically restart service without downtime.
service restart will be fired during %preun (upgrade).
manual: Manually restart service by user. If user select manual,
suppress auto-restart with automatically generated service hook
%post and %systemd_postun_with_restart.
when downgrading from v6, use manual and uninstall v6 then
reinstall v5.

When upgrading package, the following hook is executed: plugins should be installed before restarting service. Before: * old prerm * new preinst collect plugin information * old postrm auto restart * new postinst install plugins After: * old prerm collect plugin information * new preinst * old postrm * new postinst install plugins and auto restart Signed-off-by: Kentaro Hayashi <[email protected]>
fluentd_auto_restart will be launched during "configure" phase, so there is no need to check that action. This is occurred by migrating restart logic from postrm to postinst. Signed-off-by: Kentaro Hayashi <[email protected]>
It is useful to investigate maintainer scripts. Signed-off-by: Kentaro Hayashi <[email protected]>

lxc launch will fail (/var/snap/lxd/common/lxd/unix.socket: connect: permission denied) in some cases, but not sure why yet. To investigate further more, try to collect snap information when workflow was failed. Signed-off-by: Kentaro Hayashi <[email protected]>
To verify major upgrade in workflow, it needs more package build time. Signed-off-by: Kentaro Hayashi <[email protected]>

Before: * missing fluent-plugin was installed After: * missing fluent-plugin was installed * missing dependency gem was also installed NOTE: * if missing gem requires development packages to build it, it will fail. * fluent-diagtool depends on highly systemd service, so it is simple just to use fluent-gem detecting missing gems. --------- Signed-off-by: Kentaro Hayashi <[email protected]>
add test to update with auto / manual feature. Signed-off-by: Shizuo Fujita <[email protected]>
Remove environment variables that prevent the Update/Reload without downtime feature. This is because an upgrade with a Ruby version update will not work correctly due to environment variables for the old Ruby. Signed-off-by: Shizuo Fujita <[email protected]>
Since Ubuntu 24.04, needrestart package kicks service restart out of package maintainer scripts. Take back fluentd service under control for us, it had better to suppress it. NOTE: It seems that needrestart package is available from EPEL 8/9, but it is broken for a long time, so just ignore it.

Even though needrestart package was installed, service will not be restarted out of the maintainer script (hook). Signed-off-by: Kentaro Hayashi <[email protected]>

This should fix following error when build Windows package on `feature-nodowntime` branch. ``` Downloading fluentd-1.17.1 revealed dependencies not in the API or the lockfile (logger (~> 1.6)). Either installing with `--full-index` or running `bundle update fluentd` should fix the problem. rake aborted!

Update the test to ensure : * There is no issue even if an upgrade is performed that includes a Ruby major version update. * There is no data loss even if data is sent until the main process is replaced. --------- Signed-off-by: Shizuo Fujita <[email protected]>
