Subject: [pmg-devel] [PATCH pmg-api 3/4] api: spamassassin: update local channels
Date: Wed, 16 Dec 2020 18:18:12 +0100	[thread overview]
Message-ID: <20201216171813.29694-4-s.ivanov@proxmox.com> (raw)
In-Reply-To: <20201216171813.29694-1-s.ivanov@proxmox.com>

This patch adds a helper to loop over all present Spamassassin
channels files in /etc/mail/spamassassin/channel.d and:
* import the included gpg key into sa-update's keyring
* run sa-update for each channel separately

the verbose argument of the helper is for reusing the code in
pmg-daily (where we only want to log errors and be less informative)

In order to only hardcode the path of sa-update once the definition
was moved to PMG::Utils.

The choice of invoking sa-update for each channel separately is based,
instead of providing multiple '--channel' and '--gpgkey' options to
a single command was made to prevent downloading signatures, which
were signed by a key not configured for the channel.
