Can we ensure that "file" in RHEL6 identifies Python bytecode for all released versions of Python?
(i.e. 2.7, 3.0, 3.1, 3.2, and, later this year, 3.3)
I'm not sure if the Fedora work below made it into RHEL6:
+++ This bug was initially created as a clone of Bug #531082 +++
Created attachment 366152 [details]
Add bytecode values for Python 3.0 and 3.1
Description of problem:
Attached is a patch that adds support for Python 3.0 and Python 3.1 bytecode files to the .pyc/.pyo support.
With this file:
$ file /usr/lib/python3.1/re.pyo
/usr/lib/python3.1/re.pyo: python 3.1 byte-compiled
Caveat: only tested with 3.1; I calculated up the value for 3.0 from the source in python's py3k branch's Python/import.c:
Python 3.0a5: 3130 (lexical exception stacking, including POP_EXCEPT)
Python 3.1a0: 3150 (optimize conditional branches:
introduce POP_JUMP_IF_FALSE and POP_JUMP_IF_TRUE)
Note that the value has 1 added to it in py3k's _PyImport_Init,
python 3.0: magic=3131 = 0x0c3b (hex) = 0x3b 0x0c 0xc0 0xd0a (header)
python 3.1: magic=3151 = 0x0c4f (hex) = 0x4f 0x0c 0x0d 0x0a (header)

I've sent the patch to the upstream mailing list (firstname.lastname@example.org), but it's current stuck in the moderator queue as I'm not yet subscribed (they seem to require human intervention for approving subscriptions)

Well, Python releases happen faster than RHEL6 updates, so as regular rule we can't ensure that. In the time of Bug 557608, Python 2.7 and 3.2 was not released yet.
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.
Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
For information on the advisory, and where to find the updated
files, follow the link below.
If the solution does not work for you, open a new bug report.
