* Fix a crash that occurred when the PATH environment variable contained a file instead of a directory. * Add a check to ensure only directories are processed from the PATH. * Preserve existing behavior of skipping unreadable or empty directories. * Add a test case to verify that a file in PATH does not cause a crash. * Add additional tests to improve code coverage. Fixes pypa#2861 Signed-off-by: Emre Şafak <3928300+esafak@users.noreply.github.com>
…e contained a file. This was happening because I was trying to read the contents of the file as if it were a directory. To fix this, I'll now check to make sure that each entry in the PATH is a directory before I try to read from it. This will also preserve the original behavior of skipping unreadable or empty directories. I've also added a new test case to make sure that a file in the PATH doesn't cause a crash. I've also added some additional tests to improve code coverage and to fix a platform-specific issue in the test suite.
