Zope 2.2.0 beta 1
Features Changed
- Split the old CHANGES.txt into two files. CHANGES.txt will
now contain only change information for the current Zope
release. Change information for older versions is now in
the file HISTORY.txt.
- Added basic internal support for mountable databases. A separate
product will still be required to make use of this ability.
- Added a new "history" tab to selected objects (DTML methods and
documents for now) that provides access to previous versions
through the web.
- The property management screens now include the types for
existing properties.
- Added support at Python level for user-defined
__get/set/delattr__ methods on persistent objects. These
have essentially the same semantics as for Python, except
that overridden __set/delattr__ methods must explicitly
signal changes that should be persistent.
- Better error messages and syslog capabilities were added to
pcgi-wrapper (thanks to Jeff Rush).
- Calls to the ZLogger system were added to the user authentication
process to help sys admins diagnose login problems (thanks again
to Jeff Rush).
- The Undo view shows *only* transactions performed in the
place where undo was performed. (As before, it also
shows only transactions performed by users defined in the
place where the undo user is defined.)
- The way that transaction logging is done was changed to make
transaction logs based on "physical" object and user
paths. This was necessary to make undo work properly in the
presense of virtual hosts.
- A number of hooks have been added and changes made to
support products that implement virtual hosts. Keep an eye on
http://www.zope.org/Members/michel/Projects/Interfaces/ImplementingVirtualHosts
- The distributions now have an Extensions directory by default.
Bugs Fixed
- Added type checking to the constructor and edit methods of
builtin Zope object types to prevent inappropriate passing
of acquisition-wrapped objects for standard attributes (like
title, etc.). A similar restriction was added to prevent the
adding of wrapped objects as properties.
- Fixed a naming bug in MailHost that caused simple_send to
fail.
- Fixed a buglet in the rename form that caused the form to submit
to the old manage_renameObject if the user just hit the enter
key in the browser on a single item rename.
- A bug that caused the tabs to disappear after performing cache
management operations was fixed.
- A problem that prevented multiple Zope instances from running
at the same time on win32 was fixed.
- An algorithm in medusa's max_sockets.py code was updated to
improve startup time on certain platforms.
- The behavior of manage_editProperties on PropertyManagers and
PropertySheets has been fixed so that existing properties that
are not found in the update request are not reset to empty
values.
- A problem that disallowed access to the individual records in
a result set from a SQL method was fixed.
- A problem that caused the query template for an SQL method to
be rendered twice when used from the "test" tab has been fixed.
- Fix for bug #1270: Netscape Image Problems. Added casts to long
to avoid an overflow error caused when trying to convert dates
sent by certain versions of Netscape in the If-Modified-Since
header.
- Corrected DateTime.py to recognize years specified as 00 through
69 as 2000 through 2069.
- A bug that made objects named in dtml namespaces always fail
security validation was fixed. This was noticed by folks trying
to use manage_tabs from ZClasses who hit the bug because the
manage_tags document uses a namespace:
<dtml-with "_(manage_options=...">
- A change to pcgi_publisher was made to support FreeBSD, where
send() will send only 8192 bytes at a time.
- A bug that broke import in the alpha was fixed.
- A bug in the transaction handling logic could cause infinite
loops if objects were registered incorrectly.
- A bug in the transaction machinery could cause objects to
be aborted multiple times if errors occurred.
- Logging via syslog now correctly captures the process id.
- Adding User Folders and MailHosts from the management screens
didn't redirect to the correct URL after adding the object.
- A form problem that prevented joining or leaving versions
has been fixed.
- A more reasonable default content type is now used for HEAD
requests on DTML objects if the object does not have a
content_type attribute or a file-extension-like id that can
be used to determine content type.
- HTTP HEAD handling was inconsistent for collections, depending
on whether the "default document" (index_html) was acquired or
not.
