Hello Matthias, or anyone else affected,

Accepted python3.5 into xenial-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/python3.5/3.5.2-2~16.04 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

[Bug 1620754] Re: hash(datetime.datetime(...)) fails with python3.5 on armhf (on an arm64 host) with a bus error

2016-09-09 Thread Matthias Klose 
the datetime type is defined as

#define _PyTZINFO_HEAD  \
PyObject_HEAD   \
Py_hash_t hashcode; \
char hastzinfo; /* boolean flag */

typedef struct
{
_PyTZINFO_HEAD
unsigned char data[_PyDateTime_DATE_DATASIZE];
} PyDateTime_Date;

and data is used to calculate the hash of the object, not being 4 byte
aligned, you get the bus error. Inserting three fill bytes, are making
the data member 4-byte aligned solves the issue, however introducing an
ABI change makes the new datetime ABI incompatible.  For now I don't
know a solution to make that change and keep the ABI compatible.
