From 2cb6ce778804deb9666cf09a7ada787c9f7936cf Mon Sep 17 00:00:00 2001 From: Henning Schild Date: Wed, 14 Apr 2021 08:32:39 +0200 Subject: bitbake: fetch/git: add support for disabling shared clones on unpack By default the unpacker will create a "shared" clone when cloning from the DL_DIR to the WORKDIR. This patch introduces an option to control that behaviour. Imagine some recipe steps are executed in a namespace that is different from the one your downloader and unpacker ran in. (chroot) Because a "shared" clone has an absolute reference to its "alternate" you now have to make that "alternate" visible in that new namespace (chroot) at the exact place. With this patch you can unpack "noshared" and get a stand-alone copy. This copy will also work if the "alternate" is not visible or existant. The switch is a global bitbake switch and will affect all git urls. Build systems that need "noshared" most likely need it for everything they do with git.
