combo-layer: allow splitting out local config
Allow splitting the local parts of the configuration (mostly local_repo_dir and last_revision, although there is no limitation) to a side-by-side -local.conf file, with component sections optionally tagged with the combo layer branch name. This effectively allows you to: * avoid polluting the history by committing the updated last revision to the combo repository for every update * avoid putting local repo paths into the combo repository * manage multiple branches of the combo repository whilst avoiding the possibility of mixing the configuration for one branch with another. An example split configuration (note, values may be artificial): ------------------- combo-layer.conf ------------------- [bitbake] src_uri = git://git.openembedded.org/bitbake dest_dir = bitbake hook = scripts/combo-layer-hook-default.sh [oe-core] src_uri = git://git.openembedded.org/openembedded-core dest_dir = . hook = scripts/combo-layer-hook-default.sh -------------------------------------------------------- ---------------- combo-layer-local.conf ---------------- [bitbake] local_repo_dir = ../repos/bitbake [oe-core] local_repo_dir = ../repos/oe-core [bitbake|master] branch = master last_revision = db689a99beffea1a285cdfc74a58fe73f1666987 [oe-core|master] branch = master last_revision = 121a1499a81706366acc0081272a6bff634d4d62 [bitbake|denzil] branch = 1.12 last_revision = 24b631acdaa143a4de39c6e1328849660c66f219 [oe-core|denzil] branch = denzil last_revision = 741146fa90f28f7ce8d82ee7f7e254872d519724 -------------------------------------------------------- It is assumed that the local config file will be added to .gitignore.
