[New-bugs-announce] [issue15833] most failures to write byte-compiled file no longer suppressed

[Richard Oudkerk]

New submission from Richard Oudkerk:

As discussed in

    http://bugs.python.org/issue15819

trying to run python built outside a read-only source directory fails for me because OSError(EIO, ...) is raised when importlib tries to write the byte compiled file.  (I built python in a Linux VM using VMware Player which only had read-only access to the source directory.)

Currently importlib only ignores PermissionError (EACCES, EPERM) and FileExistsError (EEXIST):

    http://hg.python.org/cpython/file/d54f047312a8/Lib/importlib/_bootstrap.py#l1080

Under Python 3.2 all failures are ignored:

    http://hg.python.org/cpython/file/69952b5599b5/Python/import.c#l905

so this seems to be a regression.
