[webkit-dev] minimum python version to support

No one responded back with a summary of the Python 2.4 discussion, so
I'll attempt a summary of my own after reading--
(If you recall, we are trying to decide what Python code we write
needs to work with Python 2.4.)
The Chromium project still uses Python 2.4 in a significant way. Some
Chromium bots run new-run-webkit-tests using 2.4, and a number of
developers use 2.4 in their development environments. Generally
speaking, people support upgrading, but no one is spearheading an
upgrade and there is no ETA.
For the time being, because of the bots, it seems like
new-run-webkit-tests definitely needs to keep working with 2.4. But
for the tools used more in the development environment (webkit-patch,
etc), it seems like people would be willing to find a way to make
things work with 2.5+.
It would be pretty easy to get all of our Python code working with 2.4
(we had a patch for this a couple weeks ago), but going back wouldn't
let us use some of the nicer constructs. And we would have to contend
with at least one bug in 2.4.
(End of summary.)
Plainly, the options seem to be--
(1) All Python 2.5+
(2) All Python 2.4
(3) Some combination of (1) and (2) (e.g. new-run-webkit-tests 2.4,
everything else 2.5)
However, (1) does not seem to be an option. Personally, I'm starting
to lean more toward to (2). One reason is that we are already
starting to see a case of re-implementing in Python 2.4 (for
new-run-webkit-tests) code that was already written in 2.5:
I also think it would be helpful if we did not need to have this
discussion for each new script we decide to write in Python. I would
be willing to update the patch from a couple weeks ago that adjusts
things for 2.4.
