This commit allows to execute the test suite without thread support. Move "import trace" in test_coverage() and use test_support.import_module('trace'). ........ r80555 | victor.stinner | 2010-04-27 23:56:26 +0200 (mar., 27 avril 2010) | 6 lines Issue #7449, part 4: skip test_multiprocessing if thread support is disabled import threading after _multiprocessing to raise a more revelant error message: "No module named _multiprocessing". _multiprocessing is not compiled without thread support. ........ r80556 | victor.stinner | 2010-04-28 00:01:24 +0200 (mer., 28 avril 2010) | 8 lines Issue #7449, part 5: split Test.test_open() of ctypes/test/test_errno.py * Split Test.test_open() in 2 functions: test_open() and test_thread_open() * Skip test_open() and test_thread_open() if we are unable to find the C library * Skip test_thread_open() if thread support is disabled * Use unittest.skipUnless(os.name == "nt", ...) on test_GetLastError() ........ r80564 | victor.stinner | 2010-04-28 00:59:35 +0200 (mer., 28 avril 2010) | 4 lines Issue #7449, part 6: fix test_hashlib for missing threading module Move @test_support.reap_thread decorator from test_main() to test_threaded_hashing(). ........ r80565 | victor.stinner | 2010-04-28 01:01:29 +0200 (mer., 28 avril 2010) | 6 lines Issue #7449, part 7: simplify threading detection in test_capi * Skip TestPendingCalls if threading module is missing * Test if threading module is present or not, instead of test the presence of _testcapi._test_thread_state ........ r80566 | victor.stinner | 2010-04-28 01:03:16 +0200 (mer., 28 avril 2010) | 4 lines Issue #7449, part 8: don't skip the whole test_asynchat if threading is missing TestFifo can be executed without the threading module ........ r80568 | victor.stinner | 2010-04-28 01:14:58 +0200 (mer., 28 avril 2010) | 6 lines Issue #7449, part 9: fix test_xmlrpclib for missing threading module * Skip testcases using threads if threading module is missing * Use "http://" instead of URL in ServerProxyTestCase if threading is missing because URL is not set in this case ........ r80569 | victor.stinner | 2010-04-28 01:33:58 +0200 (mer., 28 avril 2010) | 6 lines Partial revert of r80556 (Issue #7449, part 5, fix ctypes test) Rewrite r80556: the thread test have to be executed just after the test on libc_open() and so the test cannot be splitted in two functions (without duplicating code, and I don't want to duplicate code). ........ r80570 | victor.stinner | 2010-04-28 01:51:16 +0200 (mer., 28 avril 2010) | 8 lines Issue #7449, part 10: test_cmd imports trace module using test_support.import_module() Use test_support.import_module() instead of import to raise a SkipTest exception if the import fail. Import trace fails if the threading module is missing. See also part 3: test_doctest: import trace module in test_coverage(). ........ r80571 | victor.stinner | 2010-04-28 01:55:59 +0200 (mer., 28 avril 2010) | 6 lines Issue #7449, last part (11): fix many tests if thread support is disabled * Use try/except ImportError or test_support.import_module() to import thread and threading modules * Add @unittest.skipUnless(threading, ...) to testcases using threads ........
