Some cache or buffer issues on server side about openslide-python HOT 5 CLOSED

Great idea. I've moved it to examples/deepzoom/deepzoom_multiserver.py in OpenSlide Python.

from openslide-python.

Are you seeing tiles loaded in the wrong places, or are the tiles themselves incorrect? Could you upload a screenshot?

Are you caching OpenSlide objects in your application?

from openslide-python.

This is what happens when I zoom while other client is accessing a different slide.

"Are you caching OpenSlide objects in your application?" I realy don't know. I'd changed deepzoom_server.py to serve our slides in a simple way. My main language is PHP so I've no idea about cache with Flask or pure python.

When and where do you create new OpenSlide objects? It sounds as though you might be overwriting app.slides in one worker thread while another worker thread expects it to refer to the original OpenSlide.

Here is an example server that handles multiple slide files. Notice that it maintains a cache of recently-used OpenSlide objects. This is better than reopening the slide on every tile request, since creating an OpenSlide object can be expensive.

It worked fine! Thank you very much! It solved this and some other issues.

The slidedeck is so important that I suggest you to include it in the openslide-python examples folder. I think that this code can help a lot of people.
