The bitbake logger overrode the definition of the debug() logging call to include a debug level, but this causes problems with code that may be using standard python logging, since the extra argument is interpreted differently. Instead, change the bitbake loggers debug() call to match the python logger call and add a debug2() and debug3() API to replace calls that were logging to a different debug level.

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.
