Hi, ridi here!

This bug is actually fixed with my changes (see the release notes at http://ridiculousfish.com/shell/release_notes.html). The maximum history length is now 250k unique items, with an LRU discard policy. A full history would be around 15 MB.

Processing time is one concern. fish doesn't do anything as clumsy as keeping the entire file in memory, but scanning a large history file can still add up.

But the larger concern is writing it out. fish saves its history atomically by writing an entirely new file to disk, and swapping it in. You may not notice a 100 MB file, but you would probably notice a frequent 100 MB write!

That's so you get sync'd histories across one user's logins? Good feature, but I need my history. It's invaluable to me. Still, maybe 250k lines is enough. Is there a way I could bump that up and judge for myself the consequences?

Thanks for the reply and for picking up this project. So far I'm loving the extra interactivity of fish.
