Add -S to usage message.

Rephrase error message about address in use.

zdaemon/zdaemon.py.

Also get rid of the sys.path manipulation; it doesn't work (since the
C extensions are not there).

You can now do this with the -u USER zdaemon/zdaemon.py.

XXX Not sure if berkeley still works.

Put a MinPO in the root, so that we don't actually modify the root.
Print the elapsed time for zeoup to run.

Indentation of the 2nd line is a lose, because the 2nd line can be
long.  Instead put a blank line after a record.

Add fstools module with simple utilities for jumping around in a Data.fs.

tests can do something different.

zodb3-release branch.

ZODB3-restore-debug branch, and genericized, which checks for proper
backpointers when recovering undos w/ commit and abort versions.

Merged toby-extension-method-branch - ZEO now asks its storages if there are extra methods that should be proxied by the ClientStorage. This is useful for storages which have features not covered by the standard storage API

socket errors from the recv() call and return early in that case.

considered "complete".

pointed out, interpolation is a bad name for this, since it implies something
different.

interesting root reachability properties.

and eliminate default argument hack.

Remove useless register_subsystem() calls.
Define PackError instead of raising string exception.
Remove unused _stuff argument from load().
Remove unused tid argument from _txn_undo_write().
Replace seek() and unused read()s with single read().
Remove unused local variables.

Also, add sanity checks in _getVersion() and _getSerial().

log:

    Fix an old bug in poll().  When a signal is handled while we're
    blocked in select(), this will raise select.error with errno set
    to EINTR.  The except clauses correctly ignores this error, but
    the rest of the logic will then call read() for all objects in
    select's *input* list of read file descriptors.  Then when an
    object's read_handler() is naive, it will call recv() on its
    socket, which will raise an IOError, and then asyncore decides to
    close the socket.  To fix this, we simply return in this case.

Rather than incorporating a fixed copy of asyncore.py in Zope2 and
ZODB3, I'm incorporating a fixed copy of just asyncore.poll() in this
file, since we already have a copy of asyncore.loop() here.

It looks like a bogus file position (0) was getting passed to
_getVersion(), which was returning random data for the version.

XXX Need to review this patch carefully to see why the problem was
never noticed before.  Need to add a GB unit test.
