+
+BTreeFolder2 Product
+====================
+
+BTreeFolder2 is a Zope product that acts like a Zope folder but can
+store many more items.
+
+When you fill a Zope folder with too many items, both Zope and your
+browser get overwhelmed.  Zope has to load and store a large folder
+object, and the browser has to render large HTML tables repeatedly.
+Zope can store a lot of objects, but it has trouble storing a lot of
+objects in a single standard folder.
+
+Zope Corporation once had an extensive discussion on the subject.  It
+was decided that we would expand standard folders to handle large
+numbers of objects gracefully.  Unfortunately, Zope folders are used
+and extended in so many ways today that it would be difficult to
+modify standard folders in a way that would be compatible with all
+Zope products.
+
+So the BTreeFolder product was born.  It stored all subobjects in a
+ZODB BTree, a structure designed to allow many items without loading
+them all into memory.  It also rendered the contents of the folder as
+a simple select list rather than a table.  Most browsers have no
+trouble rendering large select lists.
+
+But there was still one issue remaining.  BTreeFolders still stored
+the ID of all subobjects in a single database record.  If you put tens
+of thousands of items in a single BTreeFolder, you would still be
+loading and storing a multi-megabyte folder object.  Zope can do this,
+but not quickly, and not without bloating the database.
+
+BTreeFolder2 solves this issue.  It stores not only the subobjects but
+also the IDs of the subobjects in a BTree.  It also batches the list
+of items in the UI, showing only 1000 items at a time.  So if you
+write your application carefully, you can use a BTreeFolder2 to store
+as many items as will fit in physical storage.
+
+There are products that depend on the internal structure of the
+original BTreeFolder, however.  So rather than risk breaking those
+products, the product has been renamed.  You can have both products
+installed at the same time.  If you're developing new applications,
+you should use BTreeFolder2.
+
+
+Installation
+============
+
+Untar BTreeFolder2 in your Products directory and restart Zope.
+BTreeFolder2 will now be available in your "Add" drop-down.
+
+Additionally, if you have CMF installed, the BTreeFolder2 product also
+provides the "CMF BTree Folder" addable type.
+
+
+Usage
+=====
+
+The BTreeFolder2 user interface shows a list of items rather than a
+series of checkboxes.  To visit an item, select it in the list and
+click the "edit" button.
+
+BTreeFolder2 objects provide Python dictionary-like methods to make them
+easier to use in Python code than standard folders::
+
+    has_key(key)
+    keys()
+    values()
+    items()
+    get(key, default=None)
+    __len__()
+
+keys(), values(), and items() return sequences, but not necessarily
+tuples or lists.  Use len(folder) to call the __len__() method.  The
+objects returned by values() and items() have acquisition wrappers.
+
+BTreeFolder2 also provides a method for generating unique,
+non-overlapping IDs::
+
+    generateId(prefix='item', suffix='', rand_ceiling=999999999)
+
+The ID returned by this method is guaranteed to not clash with any
+other ID in the folder.  Use the returned value as the ID for new
+objects.  The generated IDs tend to be sequential so that objects that
+are likely related in some way get loaded together.
+
+BTreeFolder2 implements the full Folder interface, with the exception
+that the superValues() method does not return any items.  To implement
+the method in the way the Zope codebase expects would undermine the
+performance benefits gained by using BTreeFolder2.
+
+
+Repairing BTree Damage
+======================
+
+Certain ZODB bugs in the past have caused minor corruption in BTrees.
+Fortunately, the damage is apparently easy to repair.  As of version
+1.0, BTreeFolder2 provides a 'manage_cleanup' method that will check
+the internal structure of existing BTreeFolder2 instances and repair
+them if necessary.  Many thanks to Tim Peters, who fixed the BTrees
+code and provided a function for checking a BTree.
+
+Visit a BTreeFolder2 instance through the web as a manager.  Add
+"manage_cleanup" to the end of the URL and request that URL.  It may
+take some time to load and fix the entire structure.  If problems are
+detected, information will be added to the event log.
+
+
+Future
+======
+
+BTreeFolder2 will be maintained for Zope 2.  Zope 3, however, is not
+likely to require BTreeFolder, since the intention is to make Zope 3
+folders gracefully expand to support many items.
