Multiple calls to refreshSession failing

[jguadagno]

Bug report

Details

Describe the bug

After installing release 0.1.3-prerelease I am getting a lot of failed (429) POST calls to https://puffball.us-east.host.bsky.network/xrpc/com.atproto.server.refreshSession. Around 3 million a day, some are successful, but most are failing.

Expected behavior

The agent should not refresh the token so frequently

Actual behavior

The agent attempts to refresh the token multiple times a second.

Reproduction code

I have the code for the login available here: https://github.com/jguadagno/jjgnet-broadcast/blob/c43206129fbc9056659115f1770f1da747fe668a/src/JosephGuadagno.Broadcasting.Managers.Bluesky/BlueskyManager.cs#L20

The agent should not refresh the token so frequently

@jguadagno There's an understatement :)

Given you are creating a new agent instance which in turn creates a new session with every operation and then throwing the agent away it shouldn't be refreshing a session at all.

I'm wonder if the GC hasn't caught up yet, and they're all hanging around refreshing until they get collected.

A couple of things to try

1. The quick fix - turn session refresh off as you don't need it with your approach. Also as they're disposable, wrap the agent pieces in using.

2. If you can, consider a longer lived agent. The JWTs issued by BlueSky last for two hours, you could have a more central agent instantiation and pass the agent instance around, rather than create one each time, which is a slow process due to it resolving the handle and PDS.

If neither of those work I'm adding more logging to the refresh code (and giving each session an internal identifier to help correlate), and we'll start gathering logs to see what the heck is going on.

The thing that is weird is that the method (Azure Function) to post a Bluesky skeet should only be called twice a day or additionally if there is a recent blog post/video, which there hasn't been.

I've since updated the code and added a using declaration around the creation of the agent, since I only need it for the posting of the skeet.

Don't you head down that route of calling them skeets!

Let's see if that solves it, if it doesn't, I'll build a version with the debug logging, which presumably you can hook up in a function somewhere

#62 might be the root cause here.

v0.2.1-prerelease is on nuget now if you want to try that as well.
