From 04c27888d05e16791cfb5ebc3b51f9f02923775b Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Tue, 21 Mar 2023 14:48:11 +0000 Subject: bitbake: fetch2: Add autorev warning when it is set too late Bitbake expects a consistent metadata environment when it parses. There are plenty of ways you can set a recipe to autorev at a point where parts of the fetcher have already been triggered leading to obsure bugs which I struggled to debug, let alone anyone not familar with the code. If anyone is running into the message from the commit, the issue is likely one of timing. Keep in mind that the anonymous python code in base.bbclass will expand variables like FILESPATH, WORKDIR and others which contain PV. The recipe needs to be set to AUTOREV before that anonymous python runs. In particular, that means you can't set SRCREV = "${AUTOREV}" in other anonymous python, it needs to happen earlier.
