@freemo No, refreshing lands me at the same error. The error appears after ~5s. During those 5s everything but the Home timeline is loaded, Home timeline contains just a spinner, and everything is nonresponsive.

@robryk have you per chance tried doing a hard reload instead (where it refreshes your cache)? Let me try that on my end too.

@robryk i cant replicate the error here with a hard refresh... if a hard refresh doesnt fix it for you do you know how to open up a debug console so you can see what client-side errors might be logged?

@freemo Hard refresh doesn't change anything. JS console contains only the mathjax-related "CSP blocked a stylesheet" errors and the error that I pasted in pastebin.

@robryk ok decent chance the recursion thing will be the only clue... still think it might be that one post... hmm let me ask the user to delete it and see if it fixes it, one second.

@robryk ok I deleted the suspect post. Can you do another hard reload and tell me if it fixed itself maybe?

@freemo Yup, it did fix itself. Thanks.

@robryk Oh wow, ok good to know. Well thats a bug and a vulnerability. :)

@freemo The annoying thing is that I don't know of any way to edit my filters other than the web UI, so the obvious solution had a bootstrapping problem.

@robryk well the problem should never happen in the first place. It seems that our generous character limit can be exploited by just filing the limit with emojis that ultimately take way too long to run and is rendered recursively for some reason.

@robryk next update I will keep the character limit but limit the number of emojis a post can have to something generous but reasonable (maybe 50 max)

@freemo Are you able to unminify that stack trace? This might be something terribly trivial to fix properly, if I could tell what's actually happening.

@robryk I dont know an easy way to do that off hand. Usually when im testing i run a test version of the server which has unminified js and thus the stacktraces point to locations in unminimified files. I know of no easy way to do this in production where everything is minified.

Have I mentioned I hate front-end development :)

@freemo BTW. It seems that presence of this post was also making Tootle use some extreme amounts of CPU.

@robryk Thinking about this some more I wonder if it is the post where there are a ton of emoji of me someone posted.. when they did this it kept freezing my web brozer for a few seconds cause i guess it was being super slow in the background. Maybe the presence of this in your feed is breaking it?
