Python-2.6b2.tar.bz missing sig file on web site. That's about all the info I have, except that the tgz is also missing the sig file, and that 3.0b2 has it's sig file. Hope this is the correct place to report this.

Problem with PyObject_DEL in pydebug mode
by Victor Stinner July 19, 2008

July 19, 2008

Hi, I filled an issue about the crash: "import re; re.finditer("a", {})" http://bugs.python.org/issue3299 It appears quickly that the bug is specific to Python compiled in pydebug mode, or to be exact: when Py_TRACE_REFS is defined. == The Py_TRACE_REFS option == The problem is that PyObject_Del(obj) and PyObject_DEL(obj) don't remove obj from the "object list" (_ob_prev and _ob_next attributes of all objects when Py_TRACE_REFS is defined). And so obj will be reused later (maybe … [View More]

Implementing restricted Python in Zope2
by ranjith kannikara July 19, 2008

July 19, 2008

I have taken the gsoc 08 project of porting zope2 to python2.5. Through my way to the successful completion of the project I have to implement Restricted python in Zope2. I could only get the information that the python AST has not changed on moving from python2.4 to 2.5 but Restricted Python is not well documented enough for a stident to test the Zope2 's Restricted Python implentation. As a student I am not familiar with Restricted Python and python AST implementation.And in need of help to … [View More]

Progress on switching Windows build to Berkeley DB 4.7.25...
by Trent Nelson July 19, 2008

July 19, 2008

Hi all, Jesus, apologies that this has taken so long for me to get back to, I've been completely and utterly swamped with client work the past few weeks. However, thanks to a couple of hours spare at Detroit airport yesterday, I was finally able to make some progress on updating the Windows Berkeley DB build to 4.7.25. I've checked in the work I've done so far to branches/tnelson-trunk-bsddb-47-upgrade. One thing I wanted to double check with you is the following change: Modified: python/… [View More]

Change in repr of Decimal in 2.6
by Karen Tracey July 19, 2008

July 19, 2008

[Originally posted to python-list but on further reflection and some feedback I think it might be more appropriate here.] I noticed when trying out Python's 2.6b2 release that the repr of Decimal has changed since 2.5. On 2.5: Python 2.5.1 (r251:54863, Mar 7 2008, 04:10:12) [GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import decimal >>> decimal.Decimal(7) Decimal("7") >… [View More]

Issue 3008: Binary repr of floats
by Raymond Hettinger July 19, 2008

July 19, 2008

The new float.hex() is really nice. Would like to augment it with a matching float.bin() method using the same notation and normalization and leaving all the rightmost bits as Guido suggested. I think this would help demystify floats and make it straightforward to show exactly what is happening during a floating point calculation that is losing precision. def float_as_bin(x): '3.125 --> -0b1.1101000000000000000000000000000000000000000000000000p+1' hex2bin = {'0' : '0000', '1' : '… [View More]

Thanks for doing this. But see this output: http://www.python.org/dev/buildbot/all/sparc%20solaris10%20gcc%20trunk/buil… which shows that on Solaris with gcc it's 'NaN', not 'nan'. This is one of the reasons I didn't get into documenting it. And … [View More]
