Tested with Python build: trunk:54235:59936M -- the reported error occurs with Django installed (or with any __init__.py present on the path that raises an exception), and such errors indeed go away when this change is applied. ........ r59940 | georg.brandl | 2008-01-13 16:04:05 +0100 (Sun, 13 Jan 2008) | 2 lines Back out r59931 - test_ctypes fails with it. ........ r59943 | amaury.forgeotdarc | 2008-01-14 01:22:44 +0100 (Mon, 14 Jan 2008) | 6 lines As discussed in issue 1700288: ctypes takes some liberties when creating python types: it modifies the types' __dict__ directly, bypassing all the machinery of type objects which deal with special methods. And this broke recent optimisations of method lookup. Now we try to modify the type with more "official" functions. ........ r59944 | amaury.forgeotdarc | 2008-01-14 01:29:41 +0100 (Mon, 14 Jan 2008) | 5 lines Re-apply patch #1700288 (first applied in r59931, rolled back in r59940) now that ctypes uses a more supported method to create types: Method cache optimization, by Armin Rigo, ported to 2.6 by Kevin Jacobs. ........ r59946 | amaury.forgeotdarc | 2008-01-14 02:07:27 +0100 (Mon, 14 Jan 2008) | 4 lines ?Why did my tests not notice this before? Slots inheritance is very different from OO inheritance. This code lead to infinite recursion on classes derived from StructType. ........ r59947 | christian.heimes | 2008-01-14 04:33:52 +0100 (Mon, 14 Jan 2008) | 1 line Added new an better structseq representation. E.g. repr(time.gmtime(0)) now returns 'time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=0)' instead of '(1970, 1, 1, 0, 0, 0, 3, 1, 0)'. The feature is part of #1816: sys.flags ........ r59948 | christian.heimes | 2008-01-14 04:35:38 +0100 (Mon, 14 Jan 2008) | 1 line I missed the most important file ........ r59949 | christian.heimes | 2008-01-14 04:42:48 +0100 (Mon, 14 Jan 2008) | 1 line Applied patch #1816: sys.flags patch ........ r59950 | christian.heimes | 2008-01-14 05:13:37 +0100 (Mon, 14 Jan 2008) | 2 lines Now that I've learnt about structseq objects I felt like converting sys.float_info to a structseq. It's readonly and help(sys.float_info) explains the attributes nicely. ........ r59951 | christian.heimes | 2008-01-14 07:06:19 +0100 (Mon, 14 Jan 2008) | 1 line Added more comments to the new structseq repr code and implemented several of Neal's suggestions. ........
