BUG: allwise image registry searches has no results #177

Closed bsipocz closed 1 month ago

bsipocz commented 1 month ago

This used to work as of last week:

import pyvo as vo
allwise_image_services = vo.regsearch(servicetype='sia', keywords=['allwise'])

(in the latest rendered version e.g. this is the result for this cell

ivo://irsa.ipac/wise/images/allwise/l3a AllWISE L3a AllWISE Atlas (L3a) Coadd Images)

[Edit]: this points beyond allwise, I'm having trouble to get registry results for more than just a handful of IRSA services, both SIA and SIA2; so this is not really a notebook issue here but an upstream registry problem

I narrow this down to be likely a GAVO registry issue, the query has the expected result with the STScI registry, and also has the IRSA results using the EURO-VO registry, though it errors out when using keywords, but I suspect that is more related to the bug they already reported in astropy.

On EuroVO: No, that's yet another interop problem, this time related to their TAP library. We're working on figuring it out.

On the breakage: IRSA has a bug in its OAI-PMH code that kept ~1/3 of their resources out of the Heidelberg RegTAP service when it did its periodic full re-harvest last week. It's half repaired by now, but some records are still affected.

Anyway: it's not your bug, and we are working on getting the root cause fixed.

Thank you Markus. I linked your response to our backend team at IRSA, so I think all the dots are connected now.

I keep this issue open here until the notebooks are passing tests again, but also add the upstream label to show that fixing it is beyond this repo's TODO list.

Tests all pass now, big thanks for everyone getting to the bottom of the issues and fixing them so quickly!
