Re: systemd integration not working (WAS: Latest git FATAL error)

I don't know then. It works for me and I just tried it again. The only reason it would fail would be that HAVE_LIBSYSTEMD is not defined, so it would not be using libsystemd for notify support. $ sudo systemctl status dovecot ● dovecot.service - Dovecot IMAP/POP3 email server Loaded: loaded (/lib/systemd/system/dovecot.service; disabled; vendor preset: enabled) Active: active (running) since Mon 2021-04-26 10:30:02 EEST; 2s ago Docs: man:dovecot(1) https://doc.dovecot.org/ Main PID: 30213 (dovecot) Status: "v2.4.devel (98a1cca054) running" Tasks: 4 (limit: 4701) Memory: 3.3M CGroup: /system.slice/dovecot.service ├─30213 /home/cmouse/dovecot/sbin/dovecot -F ├─30214 dovecot/anvil ├─30215 dovecot/log └─30216 dovecot/config You can tell from the "Status" line that it's using Type=notify.

The current autoconf code is bit buggy, but if you do indeed have libsystemd-dev installed it should do the right thing and will work with systemd even if you have Type=notify.

This has been actually tested, so if it's not working, then something else is wrong.

Did you remember to run ./autogen.sh after pulling from git to make sure you get new configure script?

This is because you are not compiling with libsystemd-dev installed. I guess we need to make some service template that use type simple when you don't use libsystemd.

Yes, it seems fixed with this patch :)

Another bug with git, is the "type=" in systemd is switched from "simple" to "notify". The later does not work and reverting to "simple" does work

Thanks!

The chroot was needed to get the core dump.

Can you try if this does fix the crash?

The client needs to be removed from destroyed_clients linked list before it's added to client_fd_proxies linked list.
