Reference manifests in fixture collection produce error when making iiif service calls.

[aeschylus]

In http://iiif.io/api/presentation/2.0/example/fixtures/collection.json, manifests that have IIIF services return a server error page (500) when attempting to retrieve tiles.

For example: http://iiif.io/api/image/2.0/example/reference/page1-full/info.json in http://iiif.io/api/presentation/2.0/example/fixtures/29/manifest.json returns an error page or a 500 when requested with Ajax.

We're currently validating a JS API we're building for rendering multi-image objects (choice, detail, etc.) in OSD, and would like to use these in our testing. Is there a IIIF service that will respond to requests for tiles?

[azaroth42]

Works for me? Can you try again?
If it still errors, can you provide a curl or wget command that can be used to duplicate the requests you're making?

[azaroth42]

Still WFM. Propose Close Invalid.

[jpstroop]

@aeschylus can you put up a Gist w/ your AJAX code?

[aeschylus]

The Ajax request is the one sent by OpenSeadragon. So https://github.com/openseadragon/openseadragon/blob/master/src/tilesource.js#L446-L506

It seems to work now, but I was getting Python error pages.

[aeschylus]

I suppose that means this can be closed, but it would be good to consult the logs for the iiif service to see what happened.

[aeschylus]

This happened again today.

Attempting to retrieve http://iiif.io/api/image/2.0/example/reference/page1-full/info.json yields the following error page:

Ahha, got it. It's a race condition with /other/ code using the same VM and changing the working directory out of where the image server is looking for the cache. :(
I need to deploy latest version that doesn't have this race, and upgrade previous versions of the image server to do the same. I guess I get to test out the 'required review' process in SUL-DLSS ;)

[aeschylus]

Excellente!

Jon: https://github.com/openseadragon/openseadragon/blob/master/src/tilesource.js#L446-L506 is what openSeadragon was using. But this was happening when I just clicked the link.

Also, unrelated, but I saw some interesting things during my 2 hours wandering around Amsterdam before my flight:

Closing on iiif.io after making issue on the server implementation.
