Deleted news from ZODBs 3.5 and earlier; the news file was
getting ridiculously large.

- fixed the API of the pop() method on PersistentDict and PersistentMapping
- no longer try to find pop and popitem on UserDict as all supported
  Python versions have them
- added a test for the default argument of pop()
- added a NEWS.txt entry about pop()

distribution now.  Explain the differences.  Removed the
business about fiddling PYTHONPATH, because it shouldn't
be needed (and isn't for me ;-)).

deprecated in ZODB 3.4.  This should be fun ;-)

method of ZODBDatabase factories.  This gives apps
(like Zopes 2.9 and 3.2) a relatively clean way to
set up their multidatabases.  An earlier checkin
adding an optional new database_name key to
<zodb> sections.

This allows specifying part of what's needed for multidatabases
in a ZODB config file.  More to come.

docs

imported from the Zope3 tests.  Since ZODB doesn't use it,
running the ZODB tests didn't reveal that its testGhostChanged()
got broken (deliberately -- "it's a feature") in ZODB 3.6.

A wordier stab at Florent's rev 38766.

More words in the subtransaction deprecation warning.

The new text wasn't more accurate than the text it
replaced.  I'll add more words, but on the 3.5 branch
(where it belongs), and then merge that to the trunk.

tpc_abort():  Repair fubar'ed "repaired" logic.

tpc_abort():  Release the commit lock no matter what.

now is txn.savepoint(optimistic=True).

Port from 2.7 branch.

Collector 1900.

send_reply(), return_error():  Stop trying to catch an exception that doesn't
exist, when marshal.encode() raises an exception.  Jeremy simplified the
marshal.encode() half of this about 3 years ago, but apparently forgot to
change ZEO/zrpc/connection.py to match.

transactions for users defined in a non-root acl_users folder. Zope logs a
acl_users path together with a username (separated by a space) and this
previous fix failed to take this into account. Fixed by taking anything after
the last space in the compared path out of the equation.

now activates obj.

Re-add the zeoctl module to ZEO, and rewrite runzeo so
it can run as a main program (the scripts created by
mkzeoinstance.py expect to be able to do this).
