Does anyone know how to edit Misc/python.man to reflect this change? Heck, does anyone know enough Nroff or whatever to check that python.man is even vaguely up to date?

Status of undocumented distutils features in 2.4?
by Phillip J. Eby 07 Oct '04

07 Oct '04

I was looking up something in the distutils source today, and I noticed that there are some new, undocumented, and not quite complete features that were added earlier this year. Specifically, the 'requires' and 'provides' arguments to 'setup()', and the 'checkdep' command. Should these be removed for 2.4? It doesn't seem likely they'd be able to be fleshed out before the beta, especially since as far as I can recall they haven't been discussed on the Distutils-SIG yet, and some of the features don't seem to be in alignment with the relevant PEPs (e.g. PEP 262's definition of "requires" and "provides"). And, the actual current implementation of the dependency checking is (per the author's comments) "kinda hacky".

Generator expression in _strptime.py TimeRE.__init__
by Nick Coghlan 06 Oct '04

06 Oct '04

This is currently breaking the tests for me, as [:] doesn't work for generator expressions. Either TimeRE.__init__ needs to go back to using a list comp, or it needs to use list() in __seqToRE instead of [:]. Cheers, Nick. -- Nick Coghlan Brisbane, Australia

If the proposed struct module post seemed to have been a dupe, it is because it sat in a moderator queue for a few days. Sorry about that. - Josiah

Guidelines for Logging Usage
by Vinay Sajip＠RedDove 05 Oct '04

[Michael Dubner] > Main purpose of logging module is not redirection, but filtering capability. I don't agree. In general, both the redirection capability (targeting events at a particular audience) and the filtering capability (verbosity control) are important. Regards, Vinay Sajip

ConfigParser patches
by David Goodger 05 Oct '04

05 Oct '04

I have patches up on SF for two ConfigParser bugs, which I'd like to check in ASAP. Any objections? http://www.python.org/sf/1017864: Case sensitivity bug in ConfigParser ====================================================================== This is a simple bug relating to default values passed in as dictionaries, illustrated here: >>> import ConfigParser >>> cp = ConfigParser.ConfigParser({"foo": "Bar"}) >>> cp.get("DEFAULT", "Foo") 'Bar' >>> cp = ConfigParser.ConfigParser({"FOO": "Bar"}) # <-- note CAPS >>> cp.get("DEFAULT", "FOO") # same for "foo", "Foo", etc. Traceback (most recent call last): ... ConfigParser.NoOptionError: No option 'foo' in section: 'DEFAULT' The patch applies ConfigParser.optionxform to keys of defaults when supplied, to be consistent with the handling of keys of config file entries and runtime-set options. A test patch is also included. http://www.python.org/sf/997050: ConfigParser behavior change ============================================================= This may be more controversial. In Python 2.3 and earlier, ConfigParser implicitly allowed non-string values to be set. http://python.org/sf/810843 asked for clarification, and in rev 1.65 an explicit type check was added that raises TypeError. The problem is that this breaks Docutils code, and I suspect it will break other code as well, which we won't hear about until after Python 2.4 final is released. Setting non-string values worked just fine for application-internal use, as long as interpolation is turned off (RawConfigParser is used or ConfigParser with "raw" parameter set) and config files aren't written. A new SafeConfigParser class was added in Python 2.3: New applications should prefer this version if they don't need to be compatible with older versions of Python. My solution is to add the new string-only restriction to the SafeConfigParser class, leave existing ConfigParser & RawConfigParser behavior alone, and document the conditions under which non-string values work. Code, doc, and test patches included. What say you? -- David Goodger <http://python.net/~goodger>

grant applications
by Paul F. Dubois 05 Oct '04

05 Oct '04

Dear devs, You'll be pleased to learn that the PSF grants process brought in sixty-four proposals. I think that is a stunning success, and the wide variety of these proposals is a testimony to the breadth and strength of the community. We should seek some branding sponsorship in the future so we can accept more of these. I'm thinking along the likes of the "Kraft Cottage Cheese Grant".

Re: '-m' option (was RE: [Python-Dev] ConfigParser patches)
by Nick Coghlan 04 Oct '04

Quoting Paramjit Oberoi <psoberoi(a)gmail.com>: > With a slightly longer script, and a little work in the installer, > these could be written as: > > Installed: runpy.py profile demo.py > Prompt After: runpy.py -i profile demo.py > Alt install: runpy2.4.py profile demo.py > Build dir: ./runpy.py profile demo.py > - or - ./scripts/runpy.py profile demo.py Indeed, it may be possible to get those to *run*, but the problem is that the semantics of the following two commands are likely to differ: python <interpreter-options> runpy.py module <script-args> python runpy.py <interpreter-options> module <script-args And getting the semantics close enough that the remaining differences don't matter is likely to be a pain. Certainly, you won't be able to use execfile() any more, because it doesn't support passing compiler flags. And the script doesn't have to get much more complicated before it becomes _harder_ to understand and maintain than the C code required to implement '-m' (which is really pretty straightforward when it is limited to top-level modules).
