Fixed my moving _deadstate to an _internal_poll method. ........ r65472 | andrew.kuchling | 2008-08-04 01:43:43 +0000 (Mon, 04 Aug 2008) | 3 lines Bug 3228: Explicitly supply the file mode to avoid creating executable files, and add corresponding tests. Possible 2.5 backport candidate ........ r65481 | gregory.p.smith | 2008-08-04 07:33:37 +0000 (Mon, 04 Aug 2008) | 22 lines Adds a sanity check to avoid a *very rare* infinite loop due to a corrupt tls key list data structure in the thread startup path. This change is a companion to r60148 which already successfully dealt with a similar issue on thread shutdown. In particular this loop has been observed happening from this call path: #0 in find_key () #1 in PyThread_set_key_value () #2 in _PyGILState_NoteThreadState () #3 in PyThreadState_New () #4 in t_bootstrap () #5 in pthread_start_thread () I don't know how this happens but it does, *very* rarely. On more than one hardware platform. I have not been able to reproduce it manually. (A flaky mutex implementation on the system in question is one hypothesis). As with r60148, the spinning we managed to observe in the wild was due to a single list element pointing back upon itself. ........ r65518 | mark.dickinson | 2008-08-04 21:30:09 +0000 (Mon, 04 Aug 2008) | 7 lines Issue #1481296: (again!) Make conversion of a float NaN to an int or long raise ValueError instead of returning 0. Also, change the error message for conversion of an infinity to an integer, replacing 'long' by 'integer', so that it's appropriate for both long(float('inf')) and int(float('inf')). ........ r65536 | andrew.kuchling | 2008-08-05 01:00:57 +0000 (Tue, 05 Aug 2008) | 1 line Bug 3228: take a test from Niels Gustaebel's patch, and based on his patch, check for having os.stat available ........ r65581 | guido.van.rossum | 2008-08-07 18:51:38 +0000 (Thu, 07 Aug 2008) | 3 lines Patch by Ian Charnas from issue 3517.
