API: /labels doesn't work?

[onnozweers]

Dear dCache devs,

Is the API call /labels properly implemented? I can't get it to produce anything more than this:

{
  "children": [],
  "labels": []
}

Using a fairly recent 10.2 snapshot. The /namespace set-label and rm-label actions do work.

Thanks and happy new year!

Hi Onno, could you, please, try for any of you files query , with `curl` the label of the file: something like: [ https://dcachetest.grid.surfsara.nl:20443/api/v1/namespace/%2Fgroups%2Fdteam%2Fonno-tests | https://dcachetest.grid.surfsara.nl:20443/api/v1/namespace/%2Fgroups%2Fdteam%2Fonno-tests ] /?labels=true what about the issue 7727 rm-label not working, does it work? thank you cheers Marina From: "Onno Zweers" ***@***.***> To: "dCache" ***@***.***> Cc: "Subscribed" ***@***.***> Sent: Tuesday, 31 December, 2024 12:26:04 Subject: [dCache/dcache] API: `/labels` doesn't work?

Or you were talking rather about a functionality to list all existing labels?

Hi Marina,

I can see the labels of files with the /namespace call with labels=true, so that part works. But I was looking at the /labels API call. I assume the /labels call would allow filtering a directory based on labels, is that correct? Otherwise, what is the /labels call for?

My current plan (to implement in our dCache API client Ada) is to use /namespace showing children and with labels=true and use jq to filter on labels. I hope that will perform.

Cheers,
Onno
