Zooko: Yes; that's the sort of solution that's needed if we're not
allowed to assume two's complement with the extraordinary value (-
sys.maxint - 1) not a trap representation. If we are allowed to
assume this, then more efficient solutions

Mike Cowlishaw has confirmed that the tests scbx164, scbx165 (in version
2.59 of the tests) are implementation-specific, so test_decimal is doing
the right thing in skipping them. So I think this issue can be closed.
I don't think it's

Why do you say that:
There is no feasible way the bf_releasebuffer can keep track of how many
calls to it have been made.
Because that's exactly what e.g. bytearray objects do (see the
ob_exports field in Objects/bytearrayobject.c).
Antoine Pitrou pit...@free.fr added the comment:
Nice catch. I wonder whether there's a simple way of cooking up an unit
test for this (short of creating a new extension type).

keeping track of all the allocated memory seems like a waste of effort
(ie. not feasible).

Pauli Virtanen p...@iki.fi added the comment:
I think this is an implementation issue in MemoryView rather than an
issue with the buffer interface. PEP 3118 states, This same bufferinfo
structure must be passed to bf_releasebuffer (if available) when the
consumer is done with the memory. -- this

To work around this, *_releasebuf must be written so that it does not
use the view pointer passed to it -- the data structure may have been
shallow copied and any memory pointers in it may have already been freed.

It is sometimes useful to call subprocess.Popen() in setup.py of
