fish appears to hang on first startup #6295
Description
I've been meaning to try out fish on several occasions (years apart), but I always stumble upon this issue.
On my system (various versions of Ubuntu, currently 19.10) I do
- sudo apt install fish
- fish
and what happens next:
- no output
- no prompt
- laptop's fan spins up
- nothing else happens for several minutes
- I panic and kill fish that is eating all the CPU
On second run fish starts instantly.
I'm not sure how to reset the state so this happens again.
fish version: 3.0.2
OS: Ubuntu 19.10
$TERM: xterm-256color
Terminal emulator: gnome-terminal 3.34.0 (VTE 0.58.2)
I cannot reproduce this with sh -c 'env HOME=$(mktemp -d) fish'! But if I try to close the shell I spawned that way, I get a warning about active jobs, which might be a Clue.
Welcome to fish, the friendly interactive shell
mg@blynas /h/m/s/z/BTrees>
There are still jobs active:
PID Command
25573 $py $update_args >/dev/null 2>&1 &
A second attempt to exit will terminate them.
Use 'disown PID' to remove jobs from the list without terminating them.
mg@blynas /h/m/s/z/BTrees>
(this also leaves my terminal in a noecho mode, which is annoying but unrelated)
It seems that something in my home directory (its sheer size? some config file somewhere?) is causing this, but I don't know what.
