Timeline doesn't update #186

Open helioshk opened 2 years ago

helioshk commented 2 years ago

Hi After adding a timeline (for example XRS-B), the timeline seems to never get updated anymore. For example if i leave jhelioviewer running for 2 hours, no newer data is plotted, even when removing the timeline and adding it again.

That's a feature normally :) There's response caching at the HTTP client level. The server probably doesn't use or modify the Last-Modified tag (and it's impossible/difficult for it to compute such a timestamp). Solution to be investigated.

There is a new build at http://swhv.oma.be/download_test/ Does it solve the issue?

helioshk commented 2 years ago

@bogdanni Still the same, the timeline doesn't update, as far as I can tell.

When should it update? For me it would be ok, if the timeline would be updated, every time the image layer gets changed/synched/updated.

I dug deeper and I'm afraid that the problem is more complex than a simple network cache. I will have to rework the design of the code. In the meanwhile, the only solution is to close and restart JHV.

I agree that the behavior you are seeking is the desired one, unfortunately the code was not designed for that.

Ok, thanks for having a look at it. It's not that important for me. I can work around it.
