Can't download all docsets at once

[MVoloshin]

Hello. I regularly re-download Zeal with all docsets to my hard drive for archival purposes.
Recently I downloaded Zeal 0.9.1 and noticed that I can no longer download all docsets at once. If I select them all and press "Download" - all the docsets just stay at 0% forever. If I try to download any single docset after such action - I immediately get error 429 (maybe Zeal tries to download all the docsets in parallel without any queueing?). Is there any workaround?

There's indeed a basic rate limiting setup on the server side. Downloading all docsets at once is not a supported use case. The vast majority of the docsets is really updated, so constantly redownloading them just eats downstream bandwidth for very few changes. If you want a local mirror, a better approach would be fetching the whole list of docsets and their versions from api.zealdocs.org, and then downloading only new versions.

I think the real bug here is that the app is trying to download everything at once.
