[bitbake-devel] [PATCH 2/5] cooker: encode event objects to base64

[Ed Bartosh]

pickle converts python objects into the binary form that can't be
decoded to text and therefore can't be converted to JSON format.

Attempt to convert event objects raises this error:
TypeError:
    b'\x80\x03cbb.runqueue\nrunQueueTaskSkipped\nq\x00)...
    is not JSON serializable

Encoded pickled event objects to base64 to be able to convert data
structure to JSON.

[YOCTO #9803]
