Eliminated some dead code. In other cases, exported a currently unused
function, since it was a logical part of the API.
Of course this improves the API documentation. It may also sometimes
let ghc optimize code better, since it can know a function is internal
to a module.
364 modules still to go, according to
git grep -E 'module [A-Za-z.]+ where'
This reverts commit ef0e3ac22e.
Sebastian thinks best to revert this:
It seems to me the reason I needed to look at activatable sockets
might actually be a networkd bug, and I was in error about patch 0001.
On my machines (without DHCP), networkd quits after configuring the
links. I thought this had to do with network activation, but that was
probably mistaken. This was obscured by my testing the change by doing
systemctl stop/start on networkd; now that I actually unplugged the
network cable, I noticed no DBus messages are triggered by this on
this machine. Your test case might have had a similar problem
(networkd quitting on idle). Might be related to [1].
On another machine (with DHCP) networkd remains active all the time,
and patch 0002 works there. You might want to revert 0001, though:
Suppose someone’s running no manager at all, so that polling would be
required. Because networkd is still listed as activable, we would
refrain from polling – by mistake, because networkd doesn’t seem to
actually go active if we listen on its bus, and it’s listed as
activable even when it’s not configured. Connectivity-related messages
will come in when stopping/starting the service, but not when
unplugging the cable.
MountWatcher can't do this, because it uses the session dbus,
and won't have access to the new DBUS_SESSION_BUS_ADDRESS if a new session
is started.
Bumped dbus library version, FD leak in it is fixed.
Now when the dbus connection is dropped, it'll fall back to polling.
I could make it try to reconnect, but there's a FD leak in the dbus
library, so not yet.
This deals with interruptions in network connectevity, by listening
for a new network interface coming up (using dbus to see when
network-manager or wicd do it), and forcing a rescan of
