From 39a1e248c9e7adea312c5b7e1743a8e55da63e6c Mon Sep 17 00:00:00 2001 From: eldritch horrors Date: Sat, 6 Apr 2024 22:08:58 +0200 Subject: libutil: remove sinkToSource eof callback this is only used in one place, and only to set a nicer error message on EndOfFile. the only caller that actually *catches* this exception should provide an error message in that catch block rather than forcing support for setting error message so deep into the stack. copyStorePath is never called outside of PathSubstitutionGoal anyway, which catches everything.
