Hi All,
I received a report [1] and verified that virtproxyd*.socket files have broken
syntax. E.g. from virtproxyd.socket
[Unit]
Description=Libvirt proxy local socket
Before=virtproxyd.service
libvirtd.socket libvirtd-ro.socket libvirtd-admin.socket libvirtd-tcp.socket
libvirtd-tls.socket
virtproxyd.socket should 'Conflicts' with the libvirtd sockets. I suspect this
regressed in the switch to meson. I checked a libvirt 6.0.0 installation and
indeed it has
Conflicts=libvirtd.socket libvirtd-ro.socket libvirtd-admin.socket
libvirtd-tcp.socket libvirtd-tls.socket
I blame it on Monday and my mind stuck in the weekend, but I spent too much time
trying to figure out how those socket files are generated before writing this
mail. It would be much appreciated if someone can give me a nudge in the right
direction :-).
Regards,
Jim

So if not just an error/mistake somewhere, then setting
socket_$name_in and providing such a file with your needs could be a
start

The original src/remote/Makefile.inc.am code did
-e 's|[@]deps[@]|Conflicts=$(LIBVIRTD_SOCKET_UNIT_FILES)|g' \
but src/remote/meson.build just does
libvirtd_socket_conflicts = ' '.join(libvirtd_socket_unit_files)
so missing the "Conflicts=" part.

Daniel

It looks like the issue might have various root causes as I am unsure myself
about what exactly was the idea behind some of the actions in the code. But all
the .socket files are generated from `src/remote/libvirtd.socket.in` and the line which
causes trouble for you is probably this one:
https://gitlab.com/libvirt/libvirt/-/blob/a619e28dba8c/src/remote/libvirt...
This is used in `src/meson.build` to generate socket files for all the services:
https://gitlab.com/libvirt/libvirt/-/blob/a619e28dba8c/src/meson.build#L7...
The proxy daemon service lists the other sockets as dependencies here (even though it uses
variable clearly named `*_conflicts`):
https://gitlab.com/libvirt/libvirt/-/blob/a619e28dba8c/src/remote/meson.b...
and I'm not sure whether that should be prefixed with "Conflicts=" or
whether
the `conflicts` field should come into play, although it looks like it is not
used anywhere else:
https://gitlab.com/libvirt/libvirt/-/blob/a619e28dba8c/src/meson.build#L204
So long story short: I do not have a right solution for you, but I hope this can
help you figure out where to go from here.
Actually, let me check if the `deps` are used anywhere else for a unit... yep,
it is, for virtxend and it actually uses it for the whole line it needs in that
context. So maybe a simple patch like this could help?

I'm not well versed in the systemd unit files, so feel free to adjust for
whatever feels right.
I hope that helps, have a nice day.

Yeah, afaict it is not used. I can send a separate patch to remove it.
So long story short: I do not have a right solution for you, but I
hope this can
help you figure out where to go from here.
Yes, it was helpful. Thanks for all the details!
Actually, let me check if the `deps` are used anywhere else for a
unit... yep,

context. So maybe a simple patch like this could help?
Yes, I think adding the Conflicts= when the virtproxyd unit is defined is the
better way to go. I've sent your patch :-)
