python-dev Summary for 2003-09-01 through 2003-09-15
++++++++++++++++++++++++++++++++++++++++++++++++++ ++
This is a summary of traffic on the `python-dev mailing list`_ from
September 1, 2003 through September 15, 2003. It is intended to inform
the wider Python community of on-going developments on the list. To
comment on anything mentioned here, just post to `comp.lang.python`_ (or
email Removed) which is a gateway to the newsgroup) with a
subject line mentioning what you are discussing. All python-dev members
are interested in seeing ideas discussed by the community, so don't
hesitate to take a stance on something. And if all of this really
interests you then get involved and join `python-dev`_!

This is the twenty-fifth summary written by Brett Cannon (with school
looming on the horizon).

All summaries are archived at .

Please note that this summary is written using reStructuredText_ which
can be found at . Any unfamiliar
punctuation is probably markup for reST_ (otherwise it is probably
regular expression syntax or a typo =); you can safely ignore it,
although I suggest learning reST; it's simple and is accepted for `PEP
markup`_ and gives some perks for the HTML output. Also, because of the
wonders of programs that like to reformat text, I cannot guarantee you
will be able to run the text version of this summary through Docutils_
as-is unless it is from the original text file.

... _PEP Markup:

The in-development version of the documentation for Python can be found
at and should be used when looking
up any documentation on something mentioned here. PEPs (Python
Enhancement Proposals) are located at . To
view files in the Python CVS online, go to . Reported bugs
and suggested patches can be found at the SourceForge_ project page.

Summary Announcements
Summary is nice and short this time. More people went on vacation
(although Martin came back and so that helped to pick up the traffic a
little). I skipped covering some threads that are due for PEPs since
those will be more in-depth then anything I write.

I should give fair warning that starting on the 22nd of September I will
begin school. I am hoping that it will not be difficult and I will have
a carefree time in school. But if my workload becomes a burden the
Summaries might suffer. I hope they don't, though, and I am going to do
my best to make sure that doesn't happen.

If It Isn't Documented, Is It a Secret?
Some undocumented methods in readline were discovered by Philip Eby. He
asked if this was on purpose and whether he should submit a bug report
on the lack of documentation. Guido told him to go ahead and submit the
bug report.

If you ever find something undocumented in the Python source code and
there is nothing suggesting the code is meant to be hidden from the user
(it's for internal use, a comment says it is experimental, etc.), then
please file a bug report!

"You are more trouble than you are worth!", screamed the micro release
to the new feature
The topic of what should be backported for micro releases (with Python
2.3.1 looming on the horizon) came up. Originally minor improvements
were allowed in if they didn't break backwards compatibility. And of
course bugfixes have been as well as long as they didn't break code that
came to depend on the buggy behavior (really depends on how long the
bugginess has been there and how well-known it is).

But then the point of OS X 10.3 possibly becoming the largest install
base of Python of any version (it will be 2.3) came up. With rough
estimates being thrown around of 5 million installs in about a year's
time, the point that making it difficult to run Python 2.3.x code on
that size of an install base would be bad. For instance, if some small
new feature was added to 2.3.1 then any code using that feature would
not be able to run on a virgin install of OS X 10.3 (and considering
that this is Mac it should not be expected that most users will want to,
let alone know how, to add a secondary install of Python since the
original is used by the OS and thus should not be overwritten). It
looks like a more conservative patching scheme will be taken with micro

Bytecode will also continue to work between releases. Guido has always
unofficially held that position but now it has been vocalized.

Away with you ambiguous imports!
A discussion on how to create a hierarchy of loggers in the standard
library led to the idea of having a way to cause an import to come
directly from the standard library and thus remove any ambiguity from a
relative import grabbing a similarly named module from the local package.

Barry Warsaw said he was thinking of writing a PEP on this idea.

Be careful about saying something is "easy"
A word of advice about saying something is "easy" on python-dev: if you
say that you should make sure you can back up that claim because
otherwise you will be told to write the "easy" patch and that will be
the end of the discussion.

Parsing dates for datetime
There was some talk about coming up with some code to parse dates for
the datetime module. It was kind of hand-wavy since there are multiples
chunks of code that can do that in the standard library.

If you have an opinion on this (or anything for that matter), make sure
to make a post to `comp.lang.python`_ about it.
