From 6f9082f6cf2b819ed8d1f9b7da825e546d3d8b4a Mon Sep 17 00:00:00 2001 From: Antonio Ospite Date: Thu, 13 Dec 2018 23:54:36 +0100 Subject: [PATCH] populate-sparsely.sh: explain why the script exits if there is no lock The reason why the script exits if there is no lock was given in the commit message when the check was added, but reading the code after some time I could not remember it, so just put the explanation in a comment to make the life easier for the reader. --- .config/vcsh/hooks-available/populate-sparsely.sh | 3 +++ 1 file changed, 3 insertions(+) diff --git a/.config/vcsh/hooks-available/populate-sparsely.sh b/.config/vcsh/hooks-available/populate-sparsely.sh index 387ec21..53d2b3a 100755 --- a/.config/vcsh/hooks-available/populate-sparsely.sh +++ b/.config/vcsh/hooks-available/populate-sparsely.sh @@ -5,6 +5,9 @@ set -e # Only the same instance of vcsh that had the working tree fully populated is # allowed to repopulate it sparsely.
