* gh-114685: PyBuffer_FillInfo() now raises on PyBUF_{READ,WRITE} (GH-114802)Nikita Sobolev2024-02-041-0/+21
|
* gh-114685: Check flags in PyObject_GetBuffer() (GH-114707)Serhiy Storchaka2024-01-311-0/+6
| | | | | PyObject_GetBuffer() now raises a SystemError if called with PyBUF_READ or PyBUF_WRITE as flags. These flags should only be used with the PyMemoryView_* C API.

* Unmark files as executable that can't actually be executed. (GH-15353)Greg Price2019-08-211-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are plenty of legitimate scripts in the tree that begin with a `#!`, but also a few that seem to be marked executable by mistake. Found them with this command -- it gets executable files known to Git, filters to the ones that don't start with a `#!`, and then unmarks them as executable: $ git ls-files --stage \ | perl -lane 'print $F[3] if (!/^100644/)' \ | while read f; do head -c2 "$f" | grep -qxF '#!' \ || chmod a-x "$f"; \ done Looking at the list by hand confirms that we didn't sweep up any files that should have the executable bit after all. In particular * The `.psd` files are images from Photoshop. * The `.bat` files sure look like things that can be run. But we have lots of other `.bat` files, and they don't have this bit set, so it must not be needed for them. Automerge-Triggered-By: @benjaminp

| | | | | | | | | | | | | | | | | | and lifetime issues of dynamically allocated Py_buffer members (#9990) as well as crashes (#8305, #7433). Many new features have been added (See whatsnew/3.3), and the documentation has been updated extensively. The ndarray test object from _testbuffer.c implements all aspects of PEP-3118, so further development towards the complete implementation of the PEP can proceed in a test-driven manner. Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review and many ideas. - Issue #12834: Fix incorrect results of memoryview.tobytes() for non-contiguous arrays. - Issue #5231: Introduce memoryview.cast() method that allows changing format and shape without making a copy of the underlying memory.
* Breaking ground for PEP 3137 implementation:Guido van Rossum2007-10-081-56/+0
| | | | | | Get rid of buffer(). Use memoryview() in its place where possible. In a few places, do things a bit different, because memoryview() can't slice (yet).
