* bpo-32228: Reset raw_pos after unwinding the raw stream (#4858)Nitish Chandra2018-01-281-4/+10
| | | Ensure that ``truncate()`` preserves the file position (as reported by ``tell()``) after writes longer than the buffer size.

* bpo-32186: Release the GIL during lseek and fstat (#4652)Nir Soffer2017-12-011-1/+5
| | | | | | In _io_FileIO_readall_impl(), lseek() and _Py_fstat_noraise() were called without releasing the GIL. This can cause all threads to hang for unlimited time when calling FileIO.read() and the NFS server is not accessible.
* bpo-31976: Fix race condition when flushing a file is slow. (#4331)benfogle2017-11-101-5/+9

* Replace KB unit with KiB (#4293)Victor Stinner2017-11-082-2/+2
| | | | | | | | | | | kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte") means 1024 bytes. KB was misused: replace kB or KB with KiB when appropriate. Same change for MB and GB which become MiB and GiB. Change the output of Tools/iobench/iobench.py. Round also the size of the documentation from 5.5 MB to 5 MiB.

* bpo-17852: Maintain a list of BufferedWriter objects. Flush them on exit. ↵Neil Schemenauer2017-09-223-1/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#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.
* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-1/+2
| | | | | | | * group the (stateful) runtime globals into various topical structs * consolidate the topical structs under a single top-level _PyRuntimeState struct * add a check-c-globals.py script that helps identify runtime globals Other globals are excluded (see globals.txt and check-c-globals.py).

| | | | | | | Based on patch by Victor Stinner. Add private C API function _PyUnicode_AsUnicode() which is similar to PyUnicode_AsUnicode(), but checks for null characters.
* bpo-30708: Check for null characters in PyUnicode_AsWideCharString(). (#2285)Serhiy Storchaka2017-06-271-8/+1
| | | | | Raise a ValueError if the second argument is NULL and the wchar_t\* string contains null characters.
* bpo-30600: Fix error messages (condition order in Argument Clinic) (#2051)Sylvain2017-06-107-92/+92
| | | | | | | | The function '_PyArg_ParseStack()' and '_PyArg_UnpackStack' were failing (with error "XXX() takes Y argument (Z given)") before the function '_PyArg_NoStackKeywords()' was called. Thus, the latter did not raise its more meaningful error : "XXX() takes no keyword arguments".
* bpo-30601: Fix a refleak in WindowsConsoleIO (#2003)Victor Stinner2017-06-081-3/+2

* bpo-30228: FileIO seek() and tell() set seekable (#1384)Victor Stinner2017-05-021-15/+21
| | | | | | | FileIO.seek() and FileIO.tell() method now set the internal seekable attribute to avoid one syscall on open() (in buffered or text mode). The seekable property is now also more reliable since its value is set correctly on memory allocation failure.
