<p class=MsoNormal>Hello there.<o:p></o:p></p>
<p class=MsoNormal>I´m in the process of upgrading code to use python 2.7 and
the new Py_Buffer objects. I have, however, come across an inconsistency
in the documentation, both in the pep and the python docs, with the actual
implementation.<o:p></o:p></p>
<p class=MsoNormal>In addition to the different function signatures mentioned
in issue 8946, the Py_Buffer member ‚obj‘ is undocumented.<o:p></o:p></p>
<p class=MsoNormal>The inline comment in object.h mentiones that it is a
„borrowed reference“ but this appears inconsistent with the implementation of
PyBuffer_Release().<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>In short, what the documentation fails to mention (and the
pep) is whether posessing a locked Py_Buffer structure also constitutes holding
a reference to the exporting object? I think it does, but is this
guaranteed to be so? Also, is the PyBuffer_Release() guaranteed to be
„safe“ to call multiple times (as the current implementation is)?<o:p></o:p></p>
