ints not overflowing into longs?
by Derek Shockey 03 Nov '11

03 Nov '11

I just found an unexpected behavior and I'm wondering if it is a bug. In my 2.7.2 interpreter on OS X, built and installed via MacPorts, it appears that integers are not correctly overflowing into longs and instead are yielding bizarre results. I can only reproduce this when using the exponent operator with two ints (declaring either operand explicitly as long prevents the behavior). >>> 2**100 0 >>> 2**100L 1267650600228229401496703205376L >>> 20**20 -2101438300051996672 >>> 20L**20 104857600000000000000000000L >>> 10**20 7766279631452241920 >>> 10L**20L 100000000000000000000L To confirm I'm not crazy, I tried in the 2.7.1 and 2.6.7 installations included in OS X 10.7, and also a 2.7.2+ (not sure what the + is) on an Ubuntu machine and didn't see this behavior. This looks like some kind of truncation error, but I don't know much about the internals of Python and have no idea what's going on. I assume since it's only in my MacPorts installation, it must be build configuration issue that is specific to OS X, perhaps only 10.7, or MacPorts. Am I doing something wrong, and is there a way to fix it before I compile? I could find any references to this problem as a known issue. Thanks, Derek

Buildbot failures
by Antoine Pitrou 03 Nov '11

03 Nov '11

Hello, There are currently a bunch of various buildbot failures on all 3 branches. I would remind committers to regularly take a look at the buildbots, so that these failures get solved reasonably fast. Regards Antoine.

Unexpected behaviour in compileall
by Vinay Sajip 02 Nov '11

02 Nov '11

I just started getting errors in my PEP 404 / pythonv branch, but they don't at first glance appear related to the functionality of this branch. What I'm seeing is that during installation, some of the .pyc/.pyo files written by compileall have mode 600 rather than the expected 644, with the result that test_compileall fails when run from the installed Python as an unprivileged user. If I manually do sudo chmod a+r /usr/local/lib/python3.3/__pycache__/* then test_compileall works again. I added a diagnostic to compileall.py, here's an extract from the log of the subsequent installation: Listing '/usr/local/lib/python3.3'... Compiling '/usr/local/lib/python3.3/__future__.py'... Mode of [...]/__pycache__/__future__.cpython-33.pyc is 644 Compiling '/usr/local/lib/python3.3/__phello__.foo.py'...

Mode of [...]/__pycache__/_sysconfigdata.cpython-33.pyc is 600 Compiling '/usr/local/lib/python3.3/_threading_local.py'... Mode of [...]/__pycache__/_threading_local.cpython-33.pyc is 644 Compiling '/usr/local/lib/python3.3/_weakrefset.py'... Mode of [...]/__pycache__/_weakrefset.cpython-33.pyc is 600 Compiling '/usr/local/lib/python3.3/abc.py'... Mode of [...]/__pycache__/abc.cpython-33.pyc is 600 Compiling '/usr/local/lib/python3.3/aifc.py'... Mode of [...]/__pycache__/aifc.cpython-33.pyc is 644 The 600s and 644s are interspersed with no pattern immediately apparent. All the source files have mode 644, as expected. This happens on two different Posix machines - Ubuntu Natty and OS X Leopard - so doesn't seem to be related to the external environment. Can anyone shed any light as to what might be going on? Regards, Vinay Sajip

PEP 397 and idle
by David Bailey 01 Nov '11

01 Nov '11

python-dev I am being forced to support multiple versions of python on Windows platforms. I have been using PEP 397 and the execution of *.py files works great. Thank you!! My problem is idle. The various versions of idle have the same problem as the various versions of python. We were using an editor that allowed python selection, however, they stopped supporting python and we are back using idle. Any suggestions on switching versions of idle would be appreciated. Thanks Dave Bailey

Re: [Python-Dev] [Python-checkins] cpython (3.2): adjust braces a bit
by Eric V. Smith 01 Nov '11

01 Nov '11

What's the logic for adding some braces, but removing others?
