That's not right, so when level is negative, only do explicit relative import semantics. Fixes issue #7902. Thanks to Meador Inge for the patch. ........ ................ r82465 | brett.cannon | 2010-07-03 03:32:48 +0200 (sam., 03 juil. 2010) | 3 lines Make test_import a little bit more robust for cleaning up after itself in the face of a failure. ................ r83090 | brett.cannon | 2010-07-23 16:03:16 +0200 (ven., 23 juil. 2010) | 4 lines Explicitly test relative imports by reusing importlib tests.
