that are not Zope products.

Some calls to os.system('chmod') has been replaced with the more portable os.chmod() call, to make install work properly on Windows.

Merge to HEAD: The ZEO unit tests and wo_pcgi.py didn't run on Windows if the path to the python executable included a space.

someone tries to use 'client' as an argument to a zsql method.

Support getattr on PermissionRole instances to allow access to _p, _d, __name__m and __roles__ (patch submitted by Dieter Maurer in collector #161).

ZODB works around this situation, but it probably shouldn't.
AdaptableStorage doesn't allow it.

Collector #479: Catalog tab now correctly puts "Unknown" in the type column for cataloged objects with no meta_type metadata column

Merge with HEAD: Collector #256: Added a check in _doChangeUser to make sure passwords isn't encrypted twice.

_dorestore(): Adopt the FileStorage semantics for when the transaction
pointed to by prev_txn does not exist.  This can happen if we're
restoring to a storage where that transaction has been packed away.
In that case, treat prev_txn as a hint and ignore it. :)

_TransactionsIterator.__len__(): Give this a dummy (and lying)
implementation which is just good enough for Python 2.1.3 support.

the environment has been closed.  Fortunately, there's another way.

Add some more logging.

Catalog empty results are now always a LazyCat([]) rather than a LazyCat(SomeEmptySequencishThingFromTheIndexes)

read_only flag on the config object, and BerkeleyBase sets
self._is_read_only when this flag is true, but it leaves any
ReadOnlyError raising to BaseStorage.

function to clean up all the files that a FileStorage creates.
Sometimes it's handy to do a cleanup if you have the instance, other
times you only have the Data.fs file name.

i.e. reason first, then oid.  This is because there's always a reason
but sometimes there isn't an oid (so we can default arg the oid).

Fixed getLexicon so that it can properly raise an error when it cannot find the proper lexicon object.

* Changed logic for activating first sort algorithm to elminate bad performance with large result sets (20k+). The full sort is now faster for a larger proportion of cases. This algorithm is also skipped now if a sort limit value is passed.

* Full sort now handles sort limits where the limit is 25% or greater of the total result where N-Best performance degrades. This allows the application to always apply a sort limit up to and beyond the result set length.

* Added an "N-worst" sort handler to deal with forward sort limits (previously only reverse limits worked properly).

* Small optimizations to N-best/worst to wring out a few more CPU cycles.

it's configured when you see it in the log files.

* For unsorted sets, merged and non-merged results are identical (lazy results)

* For sorted sets, merged results are lazy and non-merged are lists of three tuples that can later be merged and sorted using mergeResults

The mergeResults function has been simplified greatly and now simply accepts a list of result sets in its first argument.

ZODB4.  We need to return the unpickled extension data.

object -- because we just care about one event we can simply use a
threading.Event object.  Specific changes include,

BerkeleyBase.py

    __init__(): Simplify the creation of the checkpointer and
    autopacker worker threads.

    close(): Replace autopacker.stop() with setting the Event object.
    This both kicks us out of the wait() and sets the thread's
    internal stop flag, so it's all we need.

    _WorkThread.init(): Take the `name' argument out of the
    constructor.  It was the only thing that 2/3rds of the subclasses
    needed to override, so just stick it in a class attribute.

    run(): Simplify to use the Event object.  Also, change _nextcheck
    to recalculate `now' after the work is done.  There's no telling
    how much time the work will take (it may not matter much in
    practice).

    stop(): Removed.
