From 6604ce4e512208ec559c5c0b295fbe14fcac87cf Mon Sep 17 00:00:00 2001 From: Florian Klink Date: Fri, 30 Jun 2023 13:50:14 +0200 Subject: fix(tvix/store/blobservice): write into hasher from b, not buf buf contains everything written so far, whereas b is the slice passed in the current write() call. If we copy from &buf, we end up with the wrong hash, because we keep writing the wrong data to the hash function.
