Hi,

Does anyone have an 'mbsync' home service, please? Thanks!

Kind regards
Felix

I use a service that combines mbsync and imapnotify. It's not quite
ready yet (the code could be cleaner and it should provide a way to sync
all mailboxes manually) but it's attached if you want to take a look.

I've attached my mbsync service, but I have to load it from the CLI
after logging in since it hangs the shepherd process when I try to
include it in my home config.

herd load root ~/mbsync.scm

I just run mbsync as an mcron service. I have a custom script, because I
do some weird stuff to update my mu index afterwards, but it shouldn't
be hard to figure out how to call mbsync directly.

In my home services I have this:

   (simple-service 'mail-update-script
                   home-mcron-service-type
                   ;; Update email every five minutes.
                   (list #~(job '(next-minute '(0 5 10 15 20 25 30 35 40 45 50 55))
                                "/home/carlo/.local/bin/fetch-mail")))

Obviously this doesn't handle configuring mbsync, which I do outside of
my home configuration.

Carlo

+1! I also run it using mcron. But I’ll give a try to the `imapnotify`
thingy.

I have a home service configuration for mbsync, but… it only has
1 variable: `extra-config`! It leaves room for improvement! 😅

At RDE we have a home-isync-service-type[1] to synchronize IMAP maildirs and a home-goimapnotify-service-type[2] to listen to events on the mailbox and run arbitrary actions when new mail arrive. If you use our mail features[3] this is plug and play, otherwise you can achieve the same outcome with the home services.

I'm doing something similar, with a custom script that calls mbsync and does
some additional stuff for indexing and tagging by notmuch.

I recently noticed an issue with that: it seems that the command in the mcron
job is called with an incomplete PATH. I diagnosed that by creating a
similar mcron job with the command "/usr/bin/env > ~/E". Apparently my user
profile (as defined in .profile, which is managed by guix home) is indeed
inherited by the job, except for PATH which is reset and just contains
/run/current-system/profile/bin.

This is problematic if the job wants to call a command that is not in the
system profile. A workaround would be to define the job with an explicit
reference to a package, like:

     (service
       home-mcron-service-type
       (home-mcron-configuration
         (jobs (list
                 #~(job
                   '(next-minute (range 0 60 5))
                   (string-append #$isync "/bin/mbsync inbox")
                   )))))

but this does not completely solve the issue since PATH is still reset and
any command that is called through mbsync (e.g. through a PassCmd setting)
will fail if it does not have an absolute path.

Is there a proper way to inherit PATH from the user profile in mcron jobs ?

Yes, indeed.

The "problem" was discussed, among other places, here:
<https://lists.gnu.org/archive/html/help-guix/2024-01/msg00091.html>.

Long story short: I decided to put (or inject) the full path in all my
config files.

Ha. I did receive this thread but didn't read it enough to realize this was
actually the cause of my problem (symptom: mail was not fetched automatically
anymore, it turns out the reasons were essentially the same as in your case).

My current fix is to prefix the job command with “source ~/.profile;” and keep
the config files otherwise unchanged.

Thanks !

First off, thanks for all your responses so far!

Has anyone noticed a similar PATH issue with system Mcron jobs?  I have
to do this inside my Mcron jobs:

    (setenv "PATH"
            (string-join (list "/run/setuid-programs" (getenv "PATH")) ":"))

Otherwise, the setuid copies of my executables like 'sendmail' are not
available in Mcron jobs.

Also, while I have your attention, my fellow Mcron aficionados, please
feel free to check out this little issue. [1] There goes another
afternoon...

Kind regards
Felix
