From ecbc1db7ed1f9848dee69507de8eb289b8ddeba0 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Sat, 16 Jan 2016 10:33:18 +0000 Subject: [PATCH] image: Fix instability of do_image_* checksums The do_image_* tasks contained the expanded version of DATETIME. Due to the expansion, we couldn't exclude the value from the task checksum which meant the task would rerun. We fix this by deleting the DATETIME value during expansion so we don't expand any references to at that time. This means the task's hash can be stable rather than having hardcoded date/time values. It will get expanded at execution time. This also fixes errors shown by -S: NOTE: Reparsing files to collect dependency data Writing locked sigs to /home/pokybuild/yocto-autobuilder/yocto-worker/nightly-oe-selftest/build/build/locked-sigs.inc ERROR: Bitbake's cached basehash does not match the one we just generated (/home/pokybuild/yocto-autobuilder/yocto-worker/nightly-oe-selftest/build/meta/recipes-sato/images/core-image-sato.bb.do_image_tar)!
