Connection problem causes freeze/hang

[Kovoschiz]

What steps will reproduce the problem?

1. Enable Mapillary plugin
2. Create new layer, or download data

What is the expected result?

Can open a new layer. Or shows network error from Mapillary, and skips its loading.

What happens instead?

Freeze/hang or extremely long wait, necessitating force quit. Disabling plugin solves it.

[Kovoschiz]

Apparently it happens whenever anything is stuck. This time "loading imagery preference". Now I can't start JOSM at all.

This time it's an less unbearable 5min wait. Can there be a short time out?

[GerdP]

What values do you see for these preferences? These are the defaults in seconds:

socket.timeout.connect	15
socket.timeout.read	30

[Kovoschiz]

Same. It's not changed from the default. Perhaps unrelatedly, socket.maxredirects=5 neither. Also remotecontrol.osm.download=300 , but I'm not launching from website.

I don't have connection problems now, but this was frustrating to happen when I need JOSM immediately after botching a revert (which Monicz depends on Overpass timeliness; fortunately the older Revert tool worked for small changeset). So as another solution, the loading bar on the dialog box should keep being animated. Then I won't mistake it as a freeze/hang.

[GerdP]

I can reproduce that the animation stops when I use my laptop at a place with poor WLAN connection after removing the cached files.
I don't know why that happens, my understanding was that this animation simply keeps "rotating" no matter what happens.
