Merged revisions 70734,70775,70856,70874,70876-70877 via svnmerge ........ r70734 | r.david.murray | 2009-03-30 15:04:00 -0400 (Mon, 30 Mar 2009) | 7 lines Add import_function method to test.test_support, and modify a number of tests that expect to be skipped if imports fail or functions don't exist to use import_function and import_module. The ultimate goal is to change regrtest to not skip automatically on ImportError. Checking in now to make sure the buldbots don't show any errors on platforms I can't direct test on. ........ r70775 | r.david.murray | 2009-03-30 19:05:48 -0400 (Mon, 30 Mar 2009) | 4 lines Change more tests to use import_module for the modules that should cause tests to be skipped. Also rename import_function to the more descriptive get_attribute and add a docstring. ........ r70856 | r.david.murray | 2009-03-31 14:32:17 -0400 (Tue, 31 Mar 2009) | 7 lines A few more test skips via import_module, and change import_module to return the error message produced by importlib, so that if an import in the package whose import is being wrapped is what failed the skip message will contain the name of that module instead of the name of the wrapped module. Also fixed formatting of some previous comments. ........ r70874 | r.david.murray | 2009-03-31 15:33:15 -0400 (Tue, 31 Mar 2009) | 5 lines Improve test_support.import_module docstring, remove deprecated flag from get_attribute since it isn't likely to do anything useful. ........ r70876 | r.david.murray | 2009-03-31 15:49:15 -0400 (Tue, 31 Mar 2009) | 4 lines Remove the regrtest check that turns any ImportError into a skipped test. Hopefully all modules whose imports legitimately result in a skipped test have been properly wrapped by the previous commits. ........ r70877 | r.david.murray | 2009-03-31 15:57:24 -0400 (Tue, 31 Mar 2009) | 2 lines Add NEWS entry for regrtest change. ........

(the BSDs and OS X / Darwin) Adds a unittest for fcntl.ioctl that tests what happens with both positive and negative numbers. This was done because of issue1471 but I'm not able to reproduce -that- problem in the first place on Linux 32bit or 64bit or OS X 10.4 & 10.5 32bit or 64 bit. ........ r61656 | sean.reifschneider | 2008-03-20 01:46:50 +0100 (Do, 20 Mär 2008) | 2 lines Issue #2143: Fix embedded readline() hang on SSL socket EOF. ........ r61657 | sean.reifschneider | 2008-03-20 01:50:07 +0100 (Do, 20 Mär 2008) | 2 lines Forgot to add NEWS item about smtplib SSL readline hang fix. ........ r61658 | trent.nelson | 2008-03-20 01:58:44 +0100 (Do, 20 Mär 2008) | 1 line Revert r61650; the intent of this commit was to try and address alarm failures on some of the build slaves. As Neal points out, it's called after test_main(), so it's not going to factor into the test when run via regrtest.py (and removes the original functionality that Jeffrey wanted that would kill the test if it took longer than 3 seconds to run when executing it directly during development). ........ r61663 | sean.reifschneider | 2008-03-20 04:20:48 +0100 (Do, 20 Mär 2008) | 2 lines Issue 2188: Documentation hint about disabling proxy detection. ........ r61665 | gregory.p.smith | 2008-03-20 06:41:53 +0100 (Do, 20 Mär 2008) | 7 lines Attempt to fix the Solaris Sparc 10 buildbot. It was failing with an invalid argument error on ioctl. This was caused by the added test_fcntl ioctl test that hard coded 0 as the fd to use. Without a terminal, this fails on solaris. (it passed from the command line on sol 10, both 32 and 64 bit) Also, test_ioctl exists so I moved the test into there where it belongs. ........ r61667 | georg.brandl | 2008-03-20 08:25:55 +0100 (Do, 20 Mär 2008) | 2 lines #2383: remove obsolete XXX comment in stat.py. ........
