[sugar] [PATCH] Refactor bundlebuilder

[Jameson "Chema" Quinn]

Uh oh.

I had a different version of this patch already posted in the bug, AND I was
working on a newer version.

Marcopg, in the bug (http://dev.laptop.org/ticket/2892) there's a link to
my  own version of a bundlebuilder patch (
http://dev.laptop.org/git?p=users/homunq/sugar-toolkit;a=commit;h=bb ). It's
a pity you didn't start from there. Some differences:

- Instead of passing around a config structure, I made essentially the whole
module into a class, which kept its own config and had (almost) all the
current module functions as its methods. Either way, both of us removed the
dependency on working dir; the design choice here is unimportant, but
removing the dependency is necessary for Develop.

- I did not trim out the git_ and svn_ functions, for fear that somebody
might be using them. I agree with you though, they should go (it is a
dependency that sugar should not have).

- I kept manifest. In my discussions at the time, I had wanted to do exactly
what you have done (dump manifest for .gitignore), but some people (I think
it was bemasc and m_stone, but I don't remember - it was 3 months ago)
convinced me that explicit include (manifest) was the way to go.

Also, this is precisely what I am working on now! Here is my proposal for a
new format:
http://wiki.laptop.org/go/User:Homunq/Activity_bundles_v2
In this format, the decision to include MANIFEST makes some things easier.
An arbitrary order for MANIFEST allows a future differential-versioning
datastore to deal more gracefully with file renames - the order can remain
the same. And it also gives an ordering for signatures in HASHES; this could
be accomplished by defining a canonical sort function, but to me it seems
safer to have an explicit order.

Sorry for the miscommunication - I thought that I was being noisy enough
about what I am working on, but yes, I should have taken back ownership of
the bug. But then again, you should have started from my patch, which is
posted in the bug - or did I do that wrong?
