      An internal 3.4a5 release, to incorporate savepoint fixes.

      Fixed a bug in savepoint rollback.  It's not enough to rollback
      just the savepoint being rolled back because later savepoints
      might involved data managers that hadn't joined when the savepoint
      being rolled back was created.
      
      Now, when a data manager joins and we have savepoints, we create a
      data manager savepoint for the new data manager and add the
      datamanager savepoint to all previous transaction savepoints.  Note
      that this data manager savepoint can be a special savepoint that just
      calls abort on the data manager when it is rolled back.

      Removed a "self" argument. self is normally not shown in interfaces.
      
      Removed the freeme argument.  This argument is part of the
      implementation, not the public interface.
      
      Removed the subtransaction argument.  Although it is still supported,
      it isn't part of the pblic interface.
      
      Added missing documentation of the savepoint method.

      Fixed a bug in commits with savepoints and changes since savepoints.
      Once we start using savepoints, we need to make sure that all data are
      committed through the savepoints. Otherwise, things can get committed
      in the wrong order, leading to conflicts.

      Port ZEO changes for Windows from ZODB 3.2.
      
      In addition, repaired the useless default logging in runzeo.py.
      
      Here's Sidnei's Zope 2.7 checkin comment:
      
      * Borrow Zope's 'Signal' mechanism for Windows, if available, to
        implement clean shutdown and log rotation handlers for Windows.
      
      * Back to creating a .PID for ZEO, so external programs that wish to set
        the 'signal' can get the PID and therefore derive the signal name.
        Currently only necessary on Windows but created on all platforms which
        implement os.getpid(), as long as the 'pid-filename' option is set,
        or the 'INSTANCE_HOME' environment variable can be found.

      Port from ZODB 3.2.
      
      DemoStorage:  Added implementations for registerDB() and new_oid().  As
      Tres discovered the hard way, wrapping a ZEO client storage as a
      DemoStorage base storage yields insane behavior otherwise.
      
      BaseStorage.new_oid():  Rewrite to eliminate recursion, and hence also the
      need for the undocumented and irregular `last=` argument.
      
      Other:  removed the `last=` argument to new_oid() every place that felt
      compelled to spread that insanity ;-).  Seriously, it served no purpose
      at all elsewhere, and looks like people just cut 'n pasted in fear.

      Tim Peters authored
      test_cache():  Muck with Python's warnings module.
      
      The test didn't work if run more than once (e.g., via Zope3's
      test.py's "-N <n>" argument, or via ZODB's test.py's "-L"
      argument), because the warnings module suppresses warnings
      after the first from a single line.  Made the warnings module
      report repeats of DeprecationWarnings for the duration of
      the test.

          There's really no point, because created objects will be unreachable

          non-ghostifiable, it will try to load it's state again, and then
          either it would fail or it would load non-committed state.

          See the comment in _flush_invalidations.
      
          We need to force all invalidations to take this into account, by going
          through _flush_invalidations.  I haven't done this yet, but I have
          left some XXX comments in places where it needs to be done to remind

      checkTimeoutProvokingConflicts: try to fix rare failures. · 4659d8eb
      Tim Peters authored
      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).

      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.
