* [3.8] closes bpo-27805: Ignore ESPIPE in initializing seek of append-mode ↵Benjamin Peterson2019-11-121-9/+15
| | | | | | files. (GH-17136) This change, which follows the behavior of C stdio's fdopen and Python 2's file object, allows pipes to be opened in append mode.. (cherry picked from commit 74fa9f723f700a342e582b5ad4b51a2c4801cd1c)
* [3.8] bpo-37206: Unrepresentable default values no longer represented as ↵Serhiy Storchaka2019-09-141-3/+3
| | | | | | | | | | None. (GH-13933) (GH-16141) In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values (like in the optional third parameter of getattr). "None" should be used if None is accepted as argument and passing None has the same effect as not passing the argument at all. (cherry picked from commit 279f44678c8b84a183f9eeb85e0b086228154497) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* bpo-36974: tp_print -> tp_vectorcall_offset and tp_reserved -> tp_as_async ↵Jeroen Demeyer2019-05-311-2/+2
| | | | | | | | | (GH-13464) Automatically replace tp_print -> tp_vectorcall_offset tp_compare -> tp_as_async tp_reserved -> tp_as_async
* bpo-32388: Remove cross-version binary compatibility requirement in tp_flags ↵Antoine Pitrou2019-05-291-3/+3
| | | | | | | | (GH-4944) It is now allowed to add new fields at the end of the PyTypeObject struct without having to allocate a dedicated compatibility flag in tp_flags. This will reduce the risk of running out of bits in the 32-bit tp_flags value.
* bpo-36842: Implement PEP 578 (GH-12613)Steve Dower2019-05-231-0/+4
| | | Adds sys.audit, sys.addaudithook, io.open_code, and associated C APIs.
* bpo-35081: Add Include/internal/pycore_object.h (GH-10640)Victor Stinner2018-11-211-0/+1
| | | | Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from Include/objimpl.h to Include/internal/pycore_object.h.

* bpo-24658: Fix read/write greater than 2 GiB on macOS (GH-1705)Stéphane Wirtel2018-10-171-5/+3
| | | On macOS, fix reading from and writing into a file with a size larger than 2 GiB.
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-1/+1
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
* bpo-32571: Avoid raising unneeded AttributeError and silencing it in C code ↵Serhiy Storchaka2018-01-251-5/+3
| | | | | (GH-5222) Add two new private APIs: _PyObject_LookupAttr() and _PyObject_LookupAttrId()
* 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.
* Replace KB unit with KiB (#4293)Victor Stinner2017-11-081-1/+1
| | | | | | | | | | | 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.
* [security] bpo-13617: Reject embedded null characters in wchar* strings. (#2302)Serhiy Storchaka2017-06-281-2/+1
| | | | | | | 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-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.
