But for any given user, there's only going to be a first. Either they pass the test the first time and after that authenticate via personal password, or they say WTF!! In that case we could lose all the bug reports they were ever going to write. If we're going to do CAPTCHA, what we're looking for is something that any 4 year old does automatically, but machines can't do at all. Visual recognition used to be one, but isn't any more. The CAPTCHA literature claims that segmentation still is (dividing complex images into letters), but that's nontrivial for humans, too, and I think that machines will eventually catch up. (Ie, within a handful of months.) I think it would be better to do content. URLs come to mind; without something clickable, most commercial spam would be hamstrung. But few bug reports and patches need to contain URLs, except for specialized local ones pointing to related issues. For example, how about requiring user interaction to display any post containing an URL, until an admin approves it? Or you could provide a preview containing the first two non-empty lines not containing an URL. This *would* be inconvenient for large attachments and other data where the reporter prefers to provide an URL rather than the literal data, but OTOH only people who indicate they really want to see spam would see it. ;-) ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
[Python-Dev] Need Survey Answers from Core Developers
Time is short and I'm still looking for answers to some questions about cPython, so that it makes a good showing in the Forrester survey. 1) How is the project governed? How does the community make decisions on what goes into a release? You know, I've been a member of the Python community for many years -- I know about PEPs, Guido as BDFL, and +1/-1. But I've never figured out exactly how -final- decisions are made on what goes into a release. I've never needed to, until now. Can someone explain in one paragraph? 2) Does the language have a formal defined release plan? I know Zope 3's release plan, every six months, but not that of Python. Is there a requirement to push a release out the door every N months, as some projects do, or is each release separately negotiated with developers around a planned set of features? 3) Some crude idea of how many new major and minor features were added in the last release? Yes, I know this is difficult -- the idea it so get some measure of the evolution/stability of cPython re features. Jython and IronPython are probably changing rapidly -- cPython, not such much. 4) How many committers to the cPython core are there? I don't have the necessary access to the pydotorg infrastructure to answer this -- can someone who does help me out here? Thanks for any one-line answers you can dash off to me today.

[Python-Dev] Wither PEP 335 (Overloadable Boolean Operators)?
While reviewing PEPs, I stumbled over PEP 335 ( Overloadable Boolean Operators) by Greg Ewing. I am of two minds of this -- on the one hand, it's been a long time without any working code or anything. OTOH it might be quite useful to e.g. numpy folks.

[Python-Dev] Mass PEP status changes
With the help of Neal Norwitz, Jeremy Hylton, Alex Martelli and Collin Winter, I've greatly reduced the set of open PEPs numbered less than 3000. Here's a summary. Please speak up if we've made a grave error; I take all responsibility for the final decisions. Positive Decisions (Marked Accepted or Final) - SF 237 Unifying Long Integers and Integers Zadka, GvR Marked as Final; there's no work left to be done. I 287 reStructuredText Docstring FormatGoodger Status changed from Draft to Active. SA 302 New Import Hooks JvR, Moore Marked Accepted. Should this be marked Final, or is there still an unimplemented part? SF 331 Locale-Independent Float/String Conversions Reis Marked Final; this was done years ago (Python 2.3?). Negative Decisions (Rejected, Withdrawn or Deferred) SW 228 Reworking Python's Numeric Model Zadka, GvR Withdrawn in favor of PEP 3141 (numeric ABCs). SR 256 Docstring Processing System FrameworkGoodger Rejected; seems to have run out of steam. SR 258 Docutils Design SpecificationGoodger Rejected; docutils is no longer slated for stdlib inclusion. SD 267 Optimized Access to Module NamespacesHylton Deferred; no-one has had time for this. SR 268 Extended HTTP functionality and WebDAV Stein Rejected for lack of interest or progress. SD 280 Optimizing access to globals GvR Deferred; no-one has had time for this. SW 296 Adding a bytes Object Type Gilbert Was withdrawn long ago in favor of PEP 358 (the bytes object). SR 297 Support for System Upgrades Lemburg Rejected; failed to generate support. SD 323 Copyable Iterators Martelli Deferred due to lack of interest. IR 350 Codetags Elliott Rejected for lack of will to standardize. XXX lives! SR 354 Enumerations in Python Finney Rejected; not enough interest, not sufficiently Pythonic.

[Python-Dev] Py2.6 buildouts to the set API
Here some ideas that have been proposed for sets: * New method (proposed by Shane Holloway): s1.isdisjoint(s2). Logically equivalent to "not s1.intersection(s2)" but has an early-out if a common member is found. The speed-up is potentially large given two big sets that may largely overlap or may not intersect at all.

Disjointness verification is one of my main uses for set(), and though I don't think that the early-out condition would trigger often in my code, it would increase readability. > * Additional optional arguments for basic set operations to allow > chained operations.

It's too bad that this couldn't work with the binary operator spelling: s = s1 | s2 | s3 | s4 > * Make sets listenable for changes (proposed by Jason Wells): > > s = set(mydata) > def callback(s): > print 'Set %d now has %d items' % (id(s), len(s)) > s.listeners.append(callback) > s.add(existing_element) # no callback > s.add(new_element)# callback -1 on the base set type: it seems too complex for a base set type. Also, there are various possible semantics that might be desirable, such as receiving the added element, or returning False to prevent addition. The proper place is perhaps a subclass of set with a magic method (analogous to defaultdict/__missing__). -Mike ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
Re: [Python-Dev] Wither PEP 335 (Overloadable Boolean Operators)?
"Guido van Rossum" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] | While reviewing PEPs, I stumbled over PEP 335 ( Overloadable Boolean | Operators) by Greg Ewing. I am of two minds of this -- on the one | hand, it's been a long time without any working code or anything. OTOH | it might be quite useful to e.g. numpy folks. | | It is time to reject it due to lack of interest, or revive it! Rejection would currently be fine with me, so I do not intend this to indicate 'revived interest'. But having looked at the PEP now, I have some comments in case anyone else has such. Rationale: if the only extra time without the overloads is the check of Py_TPFLAGS_HAVE_BOOLEAN_OVERLOAD then I suppose it might be 'not appreciable', but in my ignorance, I would be more persuaded by timing data ;-) Motivation: another 'workaround' is the one used in symbolic logic, dating back to Boole himself. '+' for 'or' and '*' for 'and'. But these are also needed as in in your motivating cases. A counter-motivation is that this proposal makes it even harder to reason about the behavior of Python programs. It adds one more caveat to stick in the back of ones mind. Other overloads do the same, but to me, overloading logic cuts a bit deeper. Special Methods: the proposal strikes me as clever but excessively baroque. In the absence of justification for the complexities, here is a *much* simpler version. Delete special casing of NonImplemented. __not__: substitute for default semantics when present. Delete NeedOtherOperand (where would it even live?). The current spelling is True for and and False for or, as with standard semantics. A class that does not want short circuiting, as in your motivating cases, simply defines __and1__ or __or1__ to return True or False. If the return value of __xxx1__ is not True/False, then it is the result. (I believe this matches your spec.) So the LOGICAL_XXX_1 bytecodes check for True/False identity without calling bool() on the result. Delete the reverse methods. They are only needed for mixed-type operations, like scaler*matrix. But such seems senseless here. In any case, they are not needed for any of your motivating applications, which would define both methods without mixing. If the second arg is evaluated, the result is __x2__(arg1,arg2) if defined, else arg2 as usual. Delete the 'As a special case' sentence. Type Slots: someone else can decide if a new flag and 5 new slots are a significant price. Python/C API: 5 more to learn or ignore, but that does not affect me. I do not understand what they would do or how they relate to the byte codes. Other Implementations: any possible problems? (I have no idea.)

Fine by me; if it doesn't happen often, then embargoing them would be fine. My occasional experience with distro reporting processes shows that they happen a fair amount there (often as a reference to an upstream or downstream bug report). The major ones can probably be special-cased easily as needed. > I don't get [the short preview idea], but it sounds like more work > than simple embargo. It would be. It is a use-case that according to your explanation doesn't apply to Python's tracker, so a YAGNI until proved otherwise. > I think html attachments should also be embargoed (I believe this is what I > saw a couple of months ago.) And perhaps the account uploading an html > file. Sounds OK to me, except that there are some modules that handle HTML (and XML? can that be practically distinguished from HTML?), and I would suppose people would want upload examples and test cases. ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

This seems like a good opportunity for a Cookbook Recipe for a generic listenable proxy class for container objects. Note that I could argue for the callback to be called even when the set doesn't actually change, only when the set is attempted to be changed, which to my mind pushes strongly for a recipe instead of extending sets. -- Aahz ([EMAIL PROTECTED]) <*> http://www.pythoncraft.com/ "Look, it's your affair if you want to play with five people, but don't go calling it doubles." --John Cleese anticipates Usenet ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

Sort on multiple keys is addressed by itemgetter (IMO also should be built-in). But dict.update, a list append, a deque pop could use these.

In that vein, some subclassing operation could use a list of pattern-matching / semantic membership. E.g. def every_add_op( self, op, ***data ): call_a_hook( ***data ) op( ***data ) Rings of ML. Support could be provided with def __init__... for x in ( add, update, intersection_update ): def my_x( self, ***data ): call_a_hook( ***data ) x( ***data ) setattr( self, x, my_x ) But you need to know which operations are destructive/constructive, but we can't go back and annotate the whole stdlib. Though I agree that some level of programmatic interference could be useful. Academic concern which shoots 50-50 in the real world.
