[ZODB-Dev] zodb4 renaming plans

[Jeremy Hylton]

The Zope3 grand renaming is scheduled to happen on Monday.  (And we're
taking bets about just how long it will take <0.8 wink>.)  We're going
to take advantage of the renaming to rename the zodb packages, too.

The planned directory hierarchy will change just a little.  When you
checkout ZODB4, you'll get a src directory at the same level as
setup.py and test.py.  The src directory will contain all the code --
zodb, persistence, tranaction, etc.

The plan is to convert big names to little names; that is, package and
module names will be short and lowercase.  The top-level zodb package
will be a pure namespace package that includes several related
packages as well as the main db module.

Here's a brief summary of the changes.  I've also appended a
file-by-file list of the changes.  If you've got suggestions or ideas,
we'd love to hear them soon.

Packages:
zodb
zodb/btrees  -- the well-known BTrees package
zodb/code -- the persistent module, class, and function code
zodb/storage -- a collection of storages (File, Mapping, BDB)
zodb/zeo -- the zeo package (a kind of storage)
zodb/zeo/zrpc -- the rpc protocol used by ZEO
persistence -- the basic persistence machinery
transaction -- the basic transaction machinery

I had hoped to rejigger the BTrees package so that it contained all
the BTrees, e.g. zodb.btrees.OOBTree is the OOBTree class (not a
module).  To accomplish this, we'll need to make union() and a bunch
of other functions into methods on BTrees.  There isn't time to make
that change before the renaming, but I hope it will happen afterwards.
