Is there any project whose patches are all available?

Hi, all

I want to write a version-tracking tool for Python projects, and need
some sample projects whose even smallest modifications can be
downloaded from the internet.

Could you recommend some to me?
Thanks for your reply

Not to dissuade you, but what do you hope to achieve by this?
Version-control systems are difficult to do well, and we are blessed
with an abundance of them already.

For example, by comparing two versions of a program, may be we can
generate some scripts to direct the virtual machine update a running
python program.

I had to read this sentence a couple of times, as it sounds too much like
StarTrek speak.

My guess is that you are talking about two completely unrelated things:
reloading code into the Python interpreter, and keeping track of changes in
the development of code.

I think what you have in mind is that smaller changes make code reload
easier than bigger changes, especially API changes.

.... or ABI changes in the general case, although that's not a major
difference in the Python context.

Well, most of them have ... TADA ... Versioncontrol systems they use.
Which makes ti possible to fetch all the different revisions as single
patches. So write yourself a script that exctracts these from e.g. a SVN
repo, and you are done.

If that serves your cause though, I'm not so sure.

Sure. Python itself. Do a checkout of the code from Subversion then for
any given file just ask Subversion for a diff between it and the previous
version. For example:

% pwd
/Users/skip/src/python/trunk
% svn info Lib/os.py
Path: Lib/os.py

which is no longer supported (as of Python 2.4 IIRC).

That's exactly what i want, thanks for all your replies

Hi, all

I want to write a version-tracking tool for Python projects, and need

Thanks for your reply

When the project matures, why not have the project itself hosted on
the version tracking tool?
