"Naive" alarm clocks (those which don't know from timezones) break human expectations twice a year, because their users have to be awake to fix them (or make the clock itself out-of-whack with real civil time for the hours between fixing and the actual transition). For confirmatoin, ask your local priest / pastor about the twice yearly mixups among congregants whose clocks don't self-adjust for the DST boundary: some show up late / early for church *every* time the local zone changes.

In a given application, a user who doesn't care can always write a helper function to generate hours; in an applicatino whose developer who *does* care, the 'days' argument to timedelta in its current does *not* help achieve her goal: it is an attractive nuisance she will have to learn to avoid.

Interesting. My experience is exactly the opposite: the datetimes which "application domain experts" cared about *always* needed to be non-naive (zone captured explicitly or from the user's machine and converted to UTC/GMT for storage). As with encoded bytes, allowing a naive instance inside the borders the system was always a time-bomb bug (stuff would blow up at a point far removed from which it was introduced). The instances which could have safely been naive were all logging-related, where the zone was implied by the system's timezone (nearly always UTC). I guess the difference is that I'm usually writing apps whose users can't be presumed to be in any one timezone. Even in those cases, having the logged datetimes be incomparable to user-facing ones would make them less useful.

Fixing any bug is "changing behavior"; 2.7 is not frozen for bugfixes. The real question is whether third-party code will break when the now-empty error messages appear with '?' littered through them? About the only things I can think of which might break would be doctests, but people *expect* those to break across third-dot releases of Python (one reason why I hate them). Exception repr is explicitly *not* part of any backward-compatibility guarantees in Python.

ISTM that such concerns should be addressed via some kind of paid support contract (a la RHEL), and not used to drive decisions for the underlying FLOSS project.

We've already got corrosion on the terminals the leaky batteries-included stdlib (ssl, anyone?). I see nothing wrong with rejecting additional batteries proposed purely FBO organizations who have the kind of policies you describe, but don't contribute blood-or-treasure toward their maintenannce (*especially* because they are in the "enterprise" space, and could be expected to pay for that kind of support).

My understanding of what Matt said at the language summit is that the need to support really old versions of Python 2.x (back to 2.4) is a big part of the holdup ("straddling" is *much* more painful without constraining to Python2 >= 2.6). As I heard it, the real reason for the inertia is that the Python3 port is a lot of effort / pain for zero perceived gain outside of "because it is the Right Thing(TM)." After my porting experience, I can sympathize with that sensibility, and my stuff gets an advantage (frameworks / libraries marketing to Python3 devs) that Hg doesn't (most users don't really care which Python is used to drive the standalone tool).

Michael, I can understand the frustration you feel: you have been putting effort into a labor of love geting Python support on AIX (back?) into shape, and feel that your efforts are unappreciated, or worse, that they will be waste d. The key thing to realize about the various core developers (and the broader Python and open source communities) is that their attention is a heavily over-committed resource: it isn't that folks here aren't benevolent toward your efforts, but rather that each of them (us?) makes decisions every day juggling which projects / tasks to give the minutes / hours we have available. In the common case, the "triage" involves scrathing an itch: this bug affects me / my work, that feature would make my life / my employment simpler, etc. Even where there are minutes available, the "is reviewing this feasible for me?" question kicks in. Because AIX is relatively narrow in the scope of folks it impacts, the average, overcommitted developer is likely to see a bug report, or even a pull request, which makes stuff build on AIX and say, "Hmm, I don't know enough to evalute that one, I'll leave it to folks who do know (and by implication, who have some skin in the game)." Even for more consumer-focused platforms, it has historically been harder to get attention for bugs / patches which affect only a single platform (Windows file locking semantics, or the Mac installer, etc.) One key way to get past that hurdle is to slice the size of each "thing" down as fine as possible: e.g., a pull request adding a single "#ifdef AIX" block to one file. Anything more than a screenful of diff is likely to trigger the "let someone else review it" pattern, whereas being able to scan the patch at a glance lets even a non-itchy reviewer decide, "well, at least it can't hurt anything, give it a shot." Once you've gotten a number of those small patches merged, you will find that you've built a relationship with the folks who have been reviewing them, and that they are more likely to pass them, and to review larger ones, at least in part because *you* will have learned more about what is needed in terms of code style, documentation, test coverage, etc., and *they* will have learned to trust your judgement.

FWIW, the effort of porting the "modern" bits of the Zope ecosystem (the ones I still use in Pyramid apps today, meaning the component architecture, the ZODB, and a few others) soaked up basically all of my FLOSS time between the two Santa Clara PyCons. To be fair, some of that effort went into improving test coverage, docs, etc., to ensure that the apps running against the ported librarties wouldn't break, even on Python2: but is was *not* a trivial effort.

What Stephen wrote above. Stephen was incorrect: the base64 standard is about encoding a binary stream (8-bit bites) onto another binary stream (6-bit bytes), but one which can be safely transmitted over a 7-bit-only medium.

There's no way around it. WHat does that snark have to do with this discussion? base64 has no more to do with character set encodings than it does the moon.

Given that strings are implemented in C, there is no real "iteration" happing (in the Python sense) in their methods. What stdlib code can you point to that does iterate over them in Python? I.e.: for c in stringval: ... Even if there were, aren't you proving my point? The fact that strings are implicitly iterable injects all kinds of fur into methods which take either a single value or an iterable as an argument, e.g.: def api_function(value_or_values): if isinstance(value_or_values, STRING_TYPES): value_or_values = [value_or_values] elif isinstance(value_or_values, collections.abc.Iterable): value_or_values = list(value_or_values) else: value_or_values = [value_or_values] The bugs that leaving the first test out yields pop up all over the place. >> I've always considered the fact >>> that Python made them iterable by default (rather than e.g. >>> defining a method / property to get to an iterable "view" on the >>> underlying string) > > .__iter__ is that method. But it is *on be default*: I was describing something which has to be requested in ways that don't get triggered by syntax, and doesn't make strings look "non-scalar" for APIs like the one above.

Agreed. Anything the compiler ralfs on after adding 'const' (where the actual target must be immutable) already had the fuse smoldering.

When you say "repository" > and I say "server", are we not discussing the same thing (the Bazaar > branches hosted at code.python.org)? This has been true for a number of cases over the years: whether the "repostiory format", or the wire protocol, sometimes changes which materially *improve* the user's experience may require upgrading the client on the user's machine. In the case of SVN, upgrading to 1.5 gets vastly better merging support; in the case ob bzr, the win is performance when working against a large tree. Given that all the DVCS support is experimental at this point, nobody is being *blocked* from hacking on the Python core by Barry's proposed chnage. He was trying to find out if *real* users of the bzr tree would be hurt by the repository format upgrade, rather than hypothetical ones. AFAICS, no real user (one already using bzr to work with the Python tree) has objected.

The 2.6 version of asyncore *also* breaks supervisord, which does *not* use Zope's medusa: it uses medusa 0.5.4. How is anybody supposed to write a package which sits atop a library like asyncore in a fashion portable across Python versions? The changes to the implementation in 2.6 (there is no real API) can't be reconciled, AFAICT.
