* bpo-31530: stop crashes when iterating over a file on multiple threadsbenjamin-iteration-tortureBenjamin Peterson2017-09-201-38/+67
| | | | | | | | | | | Multiple threads iterating over a file can corrupt the file's internal readahead buffer resulting in crashes. To fix this, cache buffer state thread-locally for the duration of a file_iternext call and only update the file's internal state after reading completes. No attempt is made to define or provide "reasonable" semantics for iterating over a file on multiple threads. (Non-crashing) races are still present. Duplicated, corrupt, and missing data will happen.
* consistently use Py_TYPE, Py_REFCNT, and correct initializer macros (#3563)Benjamin Peterson2017-09-1410-100/+87
| | | This no-op change makes 2.7 more consistent with 3.x to ease comparison and backports.
