My mailer just barfed trying to read that summary. The problem is that the mail comes out with the encoding: Content-Type: text/plain; charset="us-ascii" but then wants to print 'http://bugs.python.org/issue25709 opened by Árpád Kósa' Can we change the encoding to utf-8 ? Laura

The AttributeError/__getattr__ mechanism
by 王珺 27 Nov '15

27 Nov '15

Hello everyone: I'm suggesting a modification to the AttributeError/__getattr__ mechanism, see issue25634: http://bugs.python.org/issue25634 I used __getattr__ sometimes, and *descriptor* especially *property* is so widely used. I wonder whether someone had encountered the same problem with me. However, this is a complicated problem including performance issues, and backward compatibility. Thanks for your attention, Jun Wang

Fwd: Request for pronouncement on PEP 493 (HTTPS verification backport guidance)

If a distribution wishes to give users of older python versions the option of verifying certificates then they will need to backport changes authorized by previous peps. By themselves, those changes would make it so environment owners and application authors are in complete control. If an application is coded to do cert verification and the remote end has certificates that aren't recognized as valid on the client end then the user would have to change the client application code to be able to use it in their environment (or figure out how to get the ca for the remote end into their local certificate store... in extreme cases, this might be impossible - the ca cert has been lost or belongs to another company). This pep tells distributions how they might give the client end a bit more power when they backport. The settings file allows the client to toggle verification site wide. The environment variable allows clients to toggle it per application invocation. Both of these situations are better for a client than having the backport and nothing else. Both of these can be shut down by an environment owner with sufficient authority to limit what's running on the client (not sure the scope of the environment owner's powers here so I thought I should acknowledge this factor). So basically: backporting other peps (to increase security) will subtract power from the clients. This pep specifies several facilities the backporters can implement to give some of that power back to the clients. -Toshio >

collections.Counter __add__ implementation quirk
by Alexander Walters 24 Nov '15

24 Nov '15

collections.Counter.__add__ as a bit of a quirk. Counters allow for negative numbers. You can subtract from a counter into the negative no problem. However, if you have a counter with a negative value and add it to another counter, and if that value, after addition, would still be negative... that value is not included in the resulting Counter object. This is kind of weird, to the point of thinking I had a bug in other code for several hours until I went and checked how Counters are implemented. Is there any particular reason counters drop negative values when you add them together? I definitely expected them to act like ints do when you add negatives, and had to subclass it to get what I think is the obvious behavior.

Reminder: checkins into 3.5 after rc1 won't automatically go into final
by Larry Hastings 23 Nov '15

23 Nov '15

3.5.1rc1 is tagged, merged, and pushed back into the central repo. At this point I don't plan to merge further changes from hg.python.org into 3.5.1 final. If you have an important bug fix that didn't make it into 3.5.1rc1 and *has* to go into 3.5.1 final, add me to the issue and we'll talk about it. If it happens I'll have to manually cherry-pick the change. I've added a 3.5.2rc1 section to Misc/NEWS; please add new entries there. Happy holidays, //arry/

[RELEASED] Python 3.5.1rc1 is now available
by Larry Hastings 23 Nov '15

23 Nov '15

On behalf of the Python development community and the Python 3.5 release team, I'm pleased to announce the availability of Python 3.5.1rc1. Python 3.5.1 will be the first update for Python 3.5. Python 3.5 is the newest version of the Python language, and it contains many exciting new features and optimizations. You can see what's changed in Python 3.5.1rc1 (as compared to 3.5.0) here: https://docs.python.org/3.5/whatsnew/changelog.html And you can download Python 3.5.1 here: https://www.python.org/downloads/release/python-351rc1/ Windows and Mac users: please read the important platform-specific "Notes on this release" section near the end of that page. We hope you enjoy Python 3.5.1! //arry/

Release schedule for 3.4.4
by Larry Hastings 22 Nov '15

22 Nov '15

Sorry for the short notice of this schedule, but... here goes: Sat Dec 05 - tag 3.4.4rc1 Sun Dec 06 - release 3.4.4rc1 Sat Dec 19 - tag 3.4.4 final Sun Dec 20 - release 3.4.4 final The reason for the short notice: we may have to change personnel for this release, and we need to work around some holiday vacation schedules too. However, note that we have two weeks for the RC release. Because of the short notice, I plan to be a little more flexible about changes between RC1 and final. It also means we can pretty easily add a second RC if we need to. Unless something amazing happens, 3.4.4 will be the final release of 3.4 with binary installers. 3.4 will also move into "security fixes only" mode at that time. Best wishes, and again my apologies for the short notice, //arry/
