* Use names SEEK_SET, etc instead of magic number (GH-12057)ngie-eign2019-03-031-3/+3
| | | | | | | The previous code hardcoded `SEEK_SET`, etc. While it's very unlikely that these values will change, it's best to use the definitions to avoid there being mismatches in behavior with the code in the future. Signed-off-by: Enji Cooper <yaneurabeya@gmail.com>

* bpo-32236: open() emits RuntimeWarning if buffering=1 for binary mode (GH-4842)Alexey Izbyshev2018-10-201-0/+5
| | | | | | | | | If buffering=1 is specified for open() in binary mode, it is silently treated as buffering=-1 (i.e., the default buffer size). Coupled with the fact that line buffering is always supported in Python 2, such behavior caused several issues (e.g., bpo-10344, bpo-21332). Warn that line buffering is not supported if open() is called with binary mode and buffering=1.

* bpo-17852: Maintain a list of BufferedWriter objects. Flush them on exit. ↵Neil Schemenauer2017-09-221-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#3372) * Maintain a list of BufferedWriter objects. Flush them on exit. In Python 3, the buffer and the underlying file object are separate and so the order in which objects are finalized matters. This is unlike Python 2 where the file and buffer were a single object and finalization was done for both at the same time. In Python 3, if the file is finalized and closed before the buffer then the data in the buffer is lost. This change adds a doubly linked list of open file buffers. An atexit hook ensures they are flushed before proceeding with interpreter shutdown. This is addition does not remove the need to properly close files as there are other reasons why buffered data could get lost during finalization. Initial patch by Armin Rigo. * Use weakref.WeakSet instead of WeakKeyDictionary. * Simplify buffered double-linked list types. * In _flush_all_writers(), suppress errors from flush(). * Remove NEWS entry, use blurb. * Take more care when flushing file buffers from atexit. The previous implementation was not careful enough to avoid causing issues in multi-threaded cases. Check for buf->ok and buf->finalizing before actually doing the flush. Also, increase the refcnt to ensure the object does not disappear.
