launcher is sometimes very slow to pull control server changes #1910

RebeccaMahany commented 2 weeks ago

I've been noticing this lately around autoupdate settings -- I change a channel or pinned version, or request an immediate update, but launcher doesn't pull the change in a timely fashion. Currently, I've been waiting over 15 minutes for these changes to get picked up by launcher -- I set my update channel to a variety of options, but I see in the logs and kv.sqlite that the channel is still stable. I clicked the MBA to accelerate the control request interval to 5s, so I should see config changes much more quickly than I do.

I haven't done any investigation into this, so I don't know if this issue is limited to only the subsystems I've mentioned, or if it applies to all. It is also possible, though I think unlikely, that the issue is on the control server side instead.

I wonder if the changes are picked up, but somehow the effect doesn't happen. And then there's no further retry because it's not a change

It's possible, but each time I've encountered this I've made repeated control server data changes within the window (e.g. override update channel, wait a couple minutes, pin a version, wait a few minutes, request an immediate autoupdate, wait a few minutes). So if the effect isn't happening, it isn't happening across multiple sets of subsystem changes.
