Fix the methods in all fetchers so they don't change the current working directory of the calling process, which could lead to "changed cwd" warnings from bitbake.

|
|
BitBake 'Fetch' git submodules implementation
|
|
|
|
Inherits from and extends the Git fetcher to retrieve submodules of a git repository
|
|
after cloning.
|
|
|
|
SRC_URI = "gitsm://<see Git fetcher for syntax>"
|
|
|
|
See the Git fetcher, git://, for usage documentation.
|
|
|
|
NOTE: Switching a SRC_URI from "git://" to "gitsm://" requires a clean of your recipe.
