For strings fnmatch_lines converts it into a Source objects, splitted on
newlines. This is not necessary here, and it is more consistent to use
lists here in the first place.
Pytest rewrites assertions so that the items on each
side of a comoparison will have easier-to-read names
in case of an assertion error.
Before doing this, it checks to make sure the object
doesn't have a __name__ attribute; however, it uses
`hasattr` so if the objects __getattr__ is broken then
the test failure message will be the stack trace
for this failure instead of a rewritten assertion.
Unfortunately we need to get a `py.path.local` object to perform the fnmatch
operation, it is different from the standard `fnmatch` module because it
implements its own custom logic. So we need to use `py.path` to perform
the fnmatch for backward compatibility reasons.
Ideally we should be able to use a "pure path" in `pathlib` terms (a path
not bound to the file system), but we don't have those in pylib.
Fix#3973
What happens is that atomic_write on Python 2.7 on Windows will try
to convert the paths to unicode, but this triggers the import of
the encoding module for the file system codec, which in turn triggers
the rewrite, which in turn again tries to import the module, and so on.
This short-circuits the cases where we try to import another file when
writing a pyc file; I don't expect this to affect anything because
the only modules that could be affected are those imported by
atomic_writes.
