From 86124a1b3a2f0b955adfbebb3f2bd2c288837aac Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Sun, 12 Nov 2023 16:15:07 +0100 Subject: [PATCH] scripts/getver.sh: prevent asking for negative rev-parse With the case of asking an invalid version that is too big, getver.sh might return an invalid output in the form of HEAD~-2260475641. This is caused by BASE_REV - GET_REV using a negative number. Prevent this by checking if BASE_REV - GET_REV actually return 0 or a positive number and set REV variable accordingly. With the following change, invalid revision number will result in unknown printed instead of the invalid HEAD~-NUMBERS output.
