Lobby Chat infinite loop

  • Fixed

If a player's username is multi-lined (Ex: "\nBobby") and the person types a chat message in the pre-game lobby, then it will cause everyone to lock in an infinite loop.

They get caught up in scripts/widgets/text.lua:

while self.inst.TextWidget:GetRegionSize() > maxwidth do
    str = str:utf8sub(1, -2)


To fix this, an edit to scripts/widgets/redux/lobbychatqueue.lua:

group.user_widget:SetTruncatedString(data.username..":", self.username_maxwidth, 30, "..:")

Changed to:

group.user_widget:SetMultilineTruncatedString(data.username..":", self.multiline_maxrows, self.username_maxwidth, self.line_maxchars, "..:")

Of course since this is the username field it could also apply restrictions of multiline_maxrows to 1, and change the line_maxchars to the arbitrary '30' from before.

Steps to Reproduce
Have a person with a newline as the start of their username join a room and type a message, then watch the locking.

User Feedback

A developer has marked this issue as fixed. This means that the issue has been addressed in the current development build and will likely be in the next update.

Further, I would surmise that the loop only really catches if the username's disproportionally longer after the newline than before it.

"a\nBob" vs "Bob\na".
