Do people really announce new releases just over email and things like mail-archive or? Those mail archives always looked strange to me for some unknown reason.

What features/integrations make sense for a proxy with systemd? I'd assume it's only a unit that comes with the package, but that "-Ws" makes me wonder if there're deeper integrations.

If there is a mailing list for the software, why not send releases information over there? It makes a lot of sense to me. I'm also subscribed to several, and some software also announce patches or security related stuff on mail lists. I see mail as a low barrier of entry (every developer has an email address).

What else would you use to notify interested people and be able to receive feedback at the same time?

I was the person creating the patch. For now all it does is compiling in support for `Type=notify` (using sd_notify [1]) in the unit file: haproxy is able to notify systemd when it completed the `start` or the `reload`.

In the future this could be extended to support systemd's socket passing and status messages. The latter allowing you to show a short string in `systemctl status haproxy`. See this example for php-fpm:

    [root@example~]systemctl status php7.0-fpm.service 
    ● php7.0-fpm.service - The PHP 7.0 FastCGI Process Manager
       Loaded: loaded (/lib/systemd/system/php7.0-fpm.service; enabled)
       Active: active (running) since Sat 2017-11-25 13:28:22 CET; 1 day 8h ago
         Docs: man:php-fpm7.0(8)
     Main PID: 4624 (php-fpm7.0)
       Status: "Processes active: 3, idle: 29, Requests: 1203613, slow: 545, Traffic: 10.1req/sec"
    *snip*

I actually had/have an issue with the systemd-wrapper haproxy uses in 1.7 where systemd gets confused when doing a reload + a restart before all sessions are closed. This caused haproxy to completely stop accepting connections until the systemd timeout kicked in and sent a kill -9

I reported it and was told it might not affect 1.8 since the systemd-wrapper is removed there, so gonna give this a try soon. See this thread: https://www.mail-archive.com/haproxy@formilux.org/msg27404.h...

(And I switched to only doing a reload notify in Ansible together with the hard-stop-after option in haproxy which is OK for me as well in 1.7)

For going on 20 years, yes. I even add hashes for each package (i.e. the tarball & platform installers) to the end of the message and sign it. I find it odd and inconvenient when projects don't announce releases via email.

Not only do people do it, but not too long ago it was the ONLY way people did it.
