Zope trunk gets it.

development get a release tag to use.

The Persistence module no longer exists in Zope3's idea of what
ZODB is, but this test relies on it.  Make it tolerate the
absence of Persistence.

(backported from trunk revisions 29818 and 29819)

Noet that the URL doesn't exist yet.

The ZODB trunk is for 3.5 now.

This is news about ZEO protocol changes.  The promised
update of README.txt will have to be rewritten from
scratch for 3.4 (the new text in 3.3's README.txt isn't
quite right for the 3.4 release).

Rewrite ZEO protocol negotiation.

3.3 should have bumped the ZEO protocol number (new methods were
added for MVCC support), but didn't.  Untangling this is a mess.

the most common cases (commit() and abort()) -- it's not really
obvious that shortcut spelling exist for those.

Merge checkin made from a wrong project.

Believe it or not, ZopeUndo is ZEO code, not Zope code.

Merged slinkp_1726_zopeundo: avoid showing undo transactions in
the wrong folder.

This always slept for 3 seconds, waiting for the storage to
disconnect.  This loses on two counts:

1. Since the timeout is set to 1 second, it typically sleeps
   longer than necessary.

2. Since there's no predicting thread and process scheduling,
   3 seconds isn't always long enough, and rare failures have
   been reported against this test.

Instead we do a polling loop now.  This typically succeeds in
a little more than a second, speeding the normal case.  The
loop will continue trying for up to a minute if not.

Change default port # from 9999 to 8100, to match zope.conf
(well, on Zope trunk anyway -- the ZEO client example appears
to have gone missing from zope.conf on Zope3 trunk).

s/zeo/ZEO/ in logger name, to match other ZEO logger names.

Collector #1734.  Critical bug in BTree conflict resolution.

Stop silent data loss in some BTree cases where a transaction adds
a new key to a bucket while a concurrent transaction deletes all
keys from the same bucket.

Still needs porting to 3.2 line.

Various Zopes probably need changes too (to avoid the new deprecation
warnings).

Jim (Fulton) points out that it's not entirely clear that
the new format can't be read by older ZODBs, and Tim doesn't
think it's worth the bother to find out for sure.

Added news blurbs about fsIndex improvements, and about that
.index files written by 3.4 won't be readable by earlier ZODBs.

test.py ran these tests ran after "setup build_ext -i", but
not after "setup build".  Repaired by teaching setup.py to
copy more stuff out of the relevant directories.

There's a mystery:  the tests for it appear to run after
"build_ext -i", but not after "build".  But that appears
to be true for the long-stitched-in zope.interface too.

This introduces a "multi-database" concept (a simplification
of Jim's Wiki proposal), and adds many interface definitions.

Work done during the PyCon 2005 ZODB sprint, by Christian
Theune, Jim Fulton and Tim Peters.

Add a record iteration protocol to FileStorage.  You can use the record iterator to iterate over all current revisions
of data pickles in the storage.

In order to support calling via ZEO, we don't implement this as an actual iterator.  An example of using the record iterator
protocol is as follows:

storage = FileStorage('anexisting.fs')
next_oid = None
while 1:
    oid, tid, data, next_oid = storage.record_iternext(next_oid)
    # do something with oid, tid and data
    if next_oid is None:
        break

The behavior of the iteration protocol is now to iterate over all current records in the database in ascending oid order, 
although this is not a promise to do so in the future.
