Zope 2.7.0 alpha 1
Zope 2.6.1 beta 1
Bugs Fixed
- Deadlock prevention code added.
It was possible for earlier versions of ZODB to deadlock when
using multiple storages. If multiple transactions committed
concurrently and both transactions involved two or more shared
storages, deadlock was possible. This problem has been fixed
by introducing a sortKey() method to the transaction and
storage APIs that is used to define an ordering on transaction
participants. This solution will prevent deadlocks provided
that all transaction participants that use locks define a
valid sortKey() method. A warning is raised if a participant
does not define sortKey(). For backwards compatibility,
BaseStorage provides a sortKey() that uses __name__.
- Fixed bug in FileStorage related to object uncreation. An
attempt to load an uncreated object now raises KeyError.
- Fixed a couple bugs in FileStorage recover() that wrote
incorrect backpointers.
- Fixed data_txn attribute of iterator data records to use
the transaction id of the previous transaction, even if it
also has a data_txn field.
- Fixed conflict resolution bug that raised a NameError when a
class involved in a conflict could not be loaded.
- Fixed C extensions that included standard header files before
Python.h, which is not allowed.
- Added code to ThreadedAsync/LoopCallback.py to work around a
bug in asyncore.py: a handled signal can cause unwanted reads
to happen.
Features Added
- Collector #651: WebDAV Lock Manager was broken.
- The zLOG package is now backed by Vinay Sajip's "PEP 282" logger
which has been included in lib/python/logging. As a result,
the ZLogger package was removed (as its only real duty was to
handle syslog-based logging).
- Collector #646: metal:slot was lost during the I18n merge.
- Zope's shutdown process is now more careful and clean. It
avoids sending half-complete responses to clients, particularly
when running in a cluster using ICP.

- Collector #640: Fix security assertion on ZCTextIndex query method.
- ZTUtils.Iterator now handles any object that has a Python
iterator, resolving Collector #385 and #577. The
implementation is somwhat simpler, as well.
- Delayed opening the ZODB until after the "Zope" module has
been imported, fixing a deadlock issue involving ZEO. The
"Zope" module now has a "startup()" function.
- ZTUtils.Tree.TreeMaker now has additional methods for setting
various flags and attributes that influence how the tree is built,
making these aspects accessible to PythonScripts.
- Fixed a NameError in the recent change to DateTime.rfc822().
- ZTUtils.Tree.TreeMaker has a new method setStateFunction, which
allows you to set a callback function that can influence the state
(open, closed, leaf) of each node in the tree.
- Made DateTime.rfc822() simpler and independent of local timezone.
- Pidfile handling improved. When Zope is started under
zdaemon, it no longer writes its own pidfile. Instead, it
passes in the path to Z2.pid to zdaemon as its pidfile name.
The 'zProcessManager.pid' file is no longer ever written.
This caused a change to the -Z option of z2.py which should be
mostly backwards-compatible (unless people were relying on
zProcessManager.pid to be written). Now the -Z option is a
boolean. -Z1 means use a daemon. -Z0 means dont. The
default is -Z1.
- Fixed bug in Transience reported by kedai which caused spurious
KeyErrors under heavy sessioning usage.
- Collector #670: applied patch from Dieter Maurer to enhance
the Zope profiling support
- Fixed bug in the Interface Verify package; base interfaces were not
included in an interface compliancy test.
Bugs Fixed
- Collector #650: Fixed implicit list marshalling for lists where the
first two values are tainted.
- Collector #671: HTTP Ranges were broken for files and images whose
length wasn't exactly divisible by 2**16.
- ModuleSecurityInfo declarations could be lost if further declarations
were made after the Info object already had been applied. Such
additional declarations could take place in Python trusted code run
after Zope strartup or during a Product refresh.
- Collector #699: MailHosts created in 2.5 breaks in 2.6.
- Collector #694: dtml-sendmail mailto specification replaces "To:" header.
- Collector #702: DateTime.rfc822() fails without daylight saving
- Collector #651: WebDAV Lock Manager was broken.
- Collector #703: KeyErrors raised when unindexing a PathIndex should
be swallowed and logged.
- Collector #646: metal:slot was lost during the I18n merge.
Zope 2.6.0
Bugs Fixed
- Caused many places throughout the code base to use
calls to user.getId() rather than user.getUserName(). With
most (all?) user folder implementations today, this will have
no behavioral change, as getId is always alised to getUserName.
However, this makes it possible to write user folder
implementations which make the distinction between the user's
id and the user's name. These user folders will allow users
to change names independent of their identity.
- WebDAV Lock Manager actually gives the user a chance to
specify a starting path **before** searching for locks,
shortening query times and memory usage in large Zope
instances.
- PageTemplateFiles were previously owned by whatever object
contained them. This resulted in very hard bugs if the user who
owned the container was removed. Since PageTemplateFiles come
from the filesystem, they are now "unowned", similar to
DTMLFiles. Security is still applied, but now it is applied
correctly.
- Collector #411: DateTime.rfc822 is not rfc822 compliant
- Removed the signal handler hung off USR1 for packing the database.
Zope 2.6.0 beta 2
Bugs Fixed
- The ability to add multiple select properties to
PropertyManagers was broken (issue 612).
- Removed the signal handler hung off USR1 for packing the database.
This feature proved dangerous as the pack operation would happen in
the main thread, causing all asyncore operations to stop until it
the main thread, causing all asyncore operations to stop until it
was finished.
- Collector #372: tal:attributes failed when combined with tal:replace.
- Don't try to close network connections in the signal handler
for shutdown. This hosed ZEO clients.

- Fix setVirtualRoot in the face of unicode paths (such as occur
during an XML-RPC request.
- Collector #539: Fixed rendering of TAL namespace tags with an

export of an "INST_HOME" environment variable.
- Collector #580: TALES evaluateBoolean() was squishing 'default'.
- Collector #581: TALES Path traversal should not special-case a blank
string in the second element position. It now skips directly
to item access when a path element is blank or has a leading '_'.
- Fixed inconsistent attribute access in TALES Paths.
- Deprecated hasRole alias failed to return result.
- Collector #538: Hybrid path expressions no longer attempt to call
a value returned by the final, non-path alternate.
- Collector #573: ZTUtils Iterator didn't catch AttributeError.
- Deprecated hasRole alias in User.py failed to return result.
- Collector #517: The properties page incorrectly rendered properties
with non-latin1 values if there were no unicode properties defined,
and incorrectly processed properties with non-ascii names.
- Collector #580: TALES evaluateBoolean() was squishing 'default'.
- ZTUtils.SimpleTree could not build a tree with a root other than the
ZODB root object. Also, filter functions didn't work at all, let
alone in accordance with the documentation in the code.
- Collector #581: TALES Path traversal should not special-case a blank
string in the second element position. It now skips directly
to item access when a path element is blank or has a leading '_'.
- Collector #603: ZTUtils.Tree.encodeExpansion encoded depth with '.'
characters, but decodeExpansion could possibly see an encoded node
id as an encoded depth when that encoded id started with a '.'.
- Fixed inconsistent attribute access in TALES Paths.
- Collector #605: ZTUtils.Tree.decodeExpansion set no limits on the
string to be decoded, allowing for a DoS attack with very large
strings.
- The fix for issue #144 broke the ability to create an empty Image or
File object. This functionality is now reenabled again.
- ZTUtils.Zope.TreeSkipMixin allows you to skip unauthorized objects in
the tree, but the filter wasn't applied when trying to filter candidate
child nodes through a custom setChildAccess filter.
- Emails sent through MailHost now automatically include a Date header if
not already present, in compliance with RFC822 and RFC2822.
Features Added
- Add optional 'relative' argument to getURL the method in CatalogBrains.
This allows it to generate site relative URLs like absolute_url can.
- ZTUtils.Tree.encodeExpansion now will use zlib compression by default,
allowing for a far larger number of open tree states to be encoded.
decodeExpansion handles compressed expansion states automatically.
- ZTUtils.Tree.TreeMaker now has additional methods for setting
various flags and attributes that influence how the tree is built,
making these aspects accessible to PythonScripts.
