gh-114685: PyBuffer_FillInfo() now raises on PyBUF_{READ,WRITE} (GH-114802) 2024-02-04 19:16:43 +00:00

gh-114685: Check flags in PyObject_GetBuffer() (GH-114707) 
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.

gh-83791: Raise TypeError for len(memoryview_0d) (#18463)

Greg Price 9ece4a5057 Unmark files as executable that can't actually be executed. (GH-15353) 
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.

Stefan Krah 9a2d99e28a - Issue #10181: New memoryview implementation fixes multiple ownership 
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.

Guido van Rossum bae07c9baf Breaking ground for PEP 3137 implementation: 
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).
