Description

While working on a local project I found that if a SyntaxError is encountered in a file to be byte-compiled, it does not halt installation or cause setup.py to return a non-zero status code. Preferably a non-zero exit code would be returned if any errors are encountered during compilation.

Research direction

Start by reproducing the installation path in setup.py with a file containing a SyntaxError, then trace how byte-compilation reports that failure. Done means any compilation error causes installation to stop or setup.py to return a non-zero exit status.
