From 7db4f8d7747cf1c4a40fdf399a36aa9d59d92792 Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Sun, 14 Aug 2022 20:08:15 +0300 Subject: fix(tvix/eval): gently attempt to create state dir If the directory in which REPL history is stored does not exist, gently try to create it, but do not raise an error if it doesn't work. We may want to warn about it, but in general this sort of non-essential feature should not cause a hard failure.
