Add settings to control automatic refresh strategy

[flohoff]

Hi,

josm does update data needed by views unconditionally. For example when the EU StreetSign view is enabled it unconditionally updates the Sign.zip which is 42 MByte. This takes on a "low bandwidth" link e.g. 1MBit/s about 12 Minutes.

Sometimes when @home i am working behind a 384kbit/s link. I have seen startup times up to 35 Minutes.

For the very same reason i have disabled plugin auto update. Please reduce the number of network interactions to a minimum necessary and make updates like this purely optional.

Flo

Here is an excert from the startup just a couple minutes ago with josm-tested-14026.jar

One way to achieve this: Don't use remote resouces, but local ones. Instead of directly using remote resources, download them and use file: URLs. Then you can control update manually.

[flohoff]

Thats not something a normal user would be able to do. They expect to enable views/Map Paint Styles and will expect an initial download. They wont expect updates from the net causing half an hour delay on random starts.

[naoliv]

Maybe include an update policy for everything (styles, rules, etc), like we already have for plugins?

[Don-vip]

This is a very uncommon situation: downloading a giant European file provided by an external plugin using a very poor Internet connection. You should start by asking yopaseopor to not make such a big file (split by country?)

[stoecker]

Anyway I agree that we could add an similar update policy setting for the cached stuff and probably also a "cleanup" button to drop all cached files and the JOSM entries for them.

We had other requests which would be solved by such a change.

Replying to stoecker:

Good idea. But don't we already have a ticket for that? It sounds familiar.
