If we fix prepare_build_dirs to wrap the PermissionError with portage.exception.PermissionDenied, then it will be handled without showing the traceback(s) in bin/ebuild here:: > except PermissionDenied as e: > portage.writemsg("!!! Permission Denied: %s\n" % (e,), noiselevel=-1) > a = 1 We can reuse the portage.util.install_mask._raise_exc function to wrap exceptions like this (includes support for PEP 3134 exception chaining). The "TypeError: signal handler" exception message is really just noise that is normally suppressed the asyncio event loop is cleanly closed. If we use try/finally to close the event loop, then it will close cleanly even in the event of an unexpected exception like the PermissionError.
The bug has been referenced in the following commit(s): https://gitweb.gentoo.org/proj/portage.git/commit/?id=cd44fea4c8c8154fee74bcc37529c0d5c2e9d789 commit cd44fea4c8c8154fee74bcc37529c0d5c2e9d789 Author: Zac Medico <zmedico@gentoo.org> AuthorDate: 2018-05-26 05:46:36 +0000 Commit: Zac Medico <zmedico@gentoo.org> CommitDate: 2018-05-26 06:07:55 +0000 prepare_build_dirs: convert PermissionError to PermissionDenied (bug 656542) This supresses display of a big PermissionError traceback for bin/ebuild, like in https://bugs.gentoo.org/656542#c0, and also suppresses additional messages that may occur when the unhandled PermissionError prevents bin/ebuild from cleanly closing the asyncio event loop.
