yocto-compat-layer: improve error handling in signature creation
When "bitbake -k -S none world" failed, the error printed by yocto-compat-layer.py contained the stack trace multiple times and did not contain the stderr output from bitbake, making the error hard to understand and debug: INFO: ====================================================================== INFO: ERROR: test_signatures (common.CommonCompatLayer) INFO: ---------------------------------------------------------------------- INFO: Traceback (most recent call last): File "/fast/work/poky/scripts/lib/compatlayer/__init__.py", line 144, in get_signatures stderr=subprocess.PIPE) File "/usr/lib/python3.4/subprocess.py", line 620, in check_output raise CalledProcessError(retcode, process.args, output=output) subprocess.CalledProcessError: Command 'bitbake -k -S none world' returned non-zero exit status 1 During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/fast/work/poky/scripts/lib/compatlayer/cases/common.py", line 51, in test_signatures curr_sigs = get_signatures(self.td['builddir'], failsafe=True) File "/fast/work/poky/scripts/lib/compatlayer/__init__.py", line 149, in get_signatures raise RuntimeError(msg) RuntimeError: Traceback (most recent call last): File "/fast/work/poky/scripts/lib/compatlayer/__init__.py", line 144, in get_signatures stderr=subprocess.PIPE) File "/usr/lib/python3.4/subprocess.py", line 620, in check_output raise CalledProcessError(retcode, process.args, output=output) subprocess.CalledProcessError: Command 'bitbake -k -S none world' returned non-zero exit status 1 Loading cache...done.

Missing or unbuildable dependency chain was: ['zlib-qat'] ... Summary: There were 5 ERROR messages shown, returning a non-zero exit code. The yocto-compat-layer.log was incomplete, it only had the first part without the command output. stderr was missing due to stderr=subprocess.PIPE. Instead of the complicated try/except construct it's better to check the return code ourselves and raise just a single exception. The output (both on stderr and in the yocto-compat-layer.log) now is: INFO: ====================================================================== INFO: ERROR: test_signatures (common.CommonCompatLayer) INFO: ---------------------------------------------------------------------- INFO: Traceback (most recent call last): File "/fast/work/poky/scripts/lib/compatlayer/cases/common.py", line 51, in test_signatures curr_sigs = get_signatures(self.td['builddir'], failsafe=True) File "/fast/work/poky/scripts/lib/compatlayer/__init__.py", line 147, in get_signatures raise RuntimeError(msg) RuntimeError: Generating signatures failed.
