- LP #789863: Ensure that Request objects cannot be published / traversed
directly via a URL.

- Issue #27: Fix publishing of ``ZPublisher.Iterators.IStreamIterator`` under
WSGI. This interface does not have ``seek`` or ``tell``. Introduce

- Ensure that the ``WSGIPublisher`` begins and ends an *interaction*
at the request/response barrier. This is required for instance for
the ``checkPermission`` call to function without an explicit
``interaction`` parameter.

- Ensure that ObjectManager's ``get`` and ``__getitem__`` methods return only
"items" (no attributes / methods from the class or from acquisition).
Thanks to Richard Mitchell at Netsight for the report.

error message handling. (CVE-2010-1104).

- Use ``in`` operator instead of deprecated ``has_key`` method (which
is not implemented by ``OFS.ObjectManager``). This fixes an issue
with WebDAV requests for skin objects.

- Updated distributions:

- Products.ZCatalog = 2.13.22

2.13.8 (2011-06-28)

Bugs Fixed

- Fixed a serious privilege escalation issue. For more information see:

- Ensure __name__ is not None as well as __name__ existing. For example, object
could be a widget within a z3c.form MultiWidget, which do not have __name__ set.

- Testing: Re-added 'extra' argument to Functional.publish.
Removing it in Zope 2.13.0a1 did break backwards compatibility.

- LP #787541: Fix WSGIPublisher to close requests on abort unconditionally.
Previously an addAfterCommitHook was used, but this is not run on transaction
aborts. Now a Synchronizer is used which unconditionally closes the request

- Fixed ``testZODBCompat`` tests in ZopeTestCase to match modern ZODB

- LP #634942: Only require ``nt_svcutils`` on Windows.

Features Added

- Avoid conflict error hotspot in PluginIndexes' Unindex class by using
IITreeSets instead of simple ints from the start. Idea taken from

- Added date range index improvements from ``experimental.catalogqueryplan``.

where Zope2 provides its own implementations.

- LP #599378: Fixed accumulated_headers not appending to headers correctly.

- Fix support for non-public permission attributes in the
browser:view directive so that attributes which are not included in
allowed_interface or allowed_attributes but which have declarations from a
base class's security info don't get their security overwritten to be

- LP #143755: Also catch TypeError when trying to determine an
indexable value for an object in PluginIndexes.common.UnIndex

- LP #143533: Instead of showing "" as the SERVER_NAME
request variable when no specific listening IP is configured for
the HTTP server, do a socket lookup to show the current server's
fully qualified name.

which prevented renaming files and folders via FTP.

- LP #143564: Request.resolve_url did not correctly re-raise

- Removed catalog length migration code. You can no longer directly upgrade a
Zope 2.7 or earlier database to Zope 2.13. Please upgrade to an earlier
release first.

- Deprecated the ``Products.ZCatalog.CatalogAwareness`` and
``CatalogPathAwareness`` modules.

- Removed deprecated ``catalog-getObject-raises`` zope.conf option.

- Removed unmaintained HelpSys documents from ZCatalog and PluginIndexes.
Useful explanations are given inside the form templates.

- Deprecate Products.ZCatalog's current behavior of returning the entire
catalog content if no query restriction applied. In Zope 2.14 this will
result in an empty LazyCat to be returned instead.

- Deprecate acquiring the request inside Products.ZCatalog's searchResults
method if no explicit query argument is given.

- Cleaned up the Products.ZCatalog search API's. The deprecated support for
using `<index id>_usage` arguments in the request has been removed. Support
for overriding operators via the `<index id>_operator` syntax has been
limited to the query value for each index and no longer works directly on
the request. The query is now brought into a canonical form before being
passed into the `_apply_index` method of each index.

- Factored out the `Products.MailHost` package into its own distributions. It
will no longer be included by default in Zope 2.14 but live on as an
independent add-on.

Features Added

- Merged the query plan support from both ``unimr.catalogqueryplan`` and
``experimental.catalogqueryplan`` into ZCatalog. On sites with large number of
objects in a catalog (in the 100000+ range) this can significantly speed up
catalog queries. A query plan monitors catalog queries and keeps detailed
statistics about their execution. Currently the plan keeps track of execution
time, result set length and support for the ILimitedResultIndex per index for
each query. It uses this information to devise a better query execution plan
the next time the same query is run. Statistics and the resulting plan are
continuously updated. The plan is per running Zope process and not persisted.
You can inspect the plan using the ``Query Plan`` ZMI tab on each catalog
instance. The representation can be put into a Python module and the Zope
process be instructed to load this query plan on startup. The location of the
query plan is specified by providing the dotted name to the query plan
dictionary in an environment variable called ``ZCATALOGQUERYPLAN``.

- Various optimizations to indexes _apply_index and the catalog's search
method inspired by experimental.catalogqueryplan.

- Added a new ILimitedResultIndex to Products.PluginIndexes and made most
built-in indexes compatible with it. This allows indexes to consider the
already calculated result set inside their own calculations.

- Changed the internals of the DateRangeIndex to always use IITreeSet and do
an inline migration from IISet. Some datum tend to have large number of
documents, for example when using default floor or ceiling dates.

- Added a new reporting tab to `Products.ZCatalog` instances. You can use this
to get an overview of slow catalog queries, as specified by a configurable
threshold value.

- Warn when App.ImageFile.ImageFile receives a relative path with no prefix,
and then has to assume the path to be relative to "software home". This
behaviour is deprecated as packages can be factored out to their own
distribution, making the "software home" relative path meaningless.

- Updated distributions:

- AccessControl = 2.13.2
- DateTime = 2.12.5
- DocumentTemplate = 2.13.1
- Products.BTreeFolder2 = 2.13.1
- Products.OFSP = 2.13.2
- ZODB3 = 3.10.0b4

2.13.0a2 (2010-07-13)

Bugs Fixed

- Made ZPublisher tests compatible with Python 2.7.

- LP #143531: Fix broken object so they give access to their state.

- LP #578326: Add support for non-public permission attributes in the
browser:view directive.


- No longer use HelpSys pages from ``Products.OFSP`` in core Zope 2.

- No longer create an `Extensions` folder in the standard instance skeleton.
External methods will become entirely optional in Zope 2.14.

- Avoid using the ``Products.PythonScripts.standard`` module inside the
database manager ZMI.

- Factored out the `Products.BTreeFolder2`, `Products.ExternalMethod`,
`Products.MIMETools`, `Products.OFSP`, `Products.PythonScripts` and
`Products.StandardCacheManagers` packages into their own distributions. They
will no longer be included by default in Zope 2.14 but live on as independent

- Factored out the `Products.ZSQLMethods` into its own distribution. The
distribution also includes the `Shared.DC.ZRDB` code. The Zope2 distribution
no longer includes the code automatically. Please depend on the new
distribution yourself, if you use the functionality. To make the transition
easier this change has been backported to Zope 2.12.9, so you can depend on
the new distribution already in packages requiring at least that version of
Zope 2.

- Made both `Shared` and `Shared.DC` namespace packages.

- Removed fallback code for old Python versions from

- Removed fallback code for old `ZCatalog.catalog_object` function signatures
from `Products.ZCatalog.ZCatalog.reindexIndex`.

Features Added

- Added official support for Python 2.7.

- Added a new API ``get_packages_to_initialize`` to ``OFS.metaconfigure``.
This replaces any direct access to ``Products._packages_to_initialize``.
The OFS.Application.install_package function takes care of removing entries
from this list now.

- Added notification of ``IDatabaseOpenedWithRoot``.

- Added a new API's ``get_registered_packages, set_registered_packages`` to
``OFS.metaconfigure`` which replace any direct access to

- Changed product install so it won't write persistent changes only to abort
them. Instead we don't make any database changes in the first place.

- Disabled persistent product installation in the default test configuration.

- Directly extend and use the Zope Toolkit KGS release 1.0a2 from

- Updated distributions:

- DateTime = 2.12.4
- nt_svcutils = 2.13.0

2.13.0a1 (2010-06-25)

This release includes all bug fixes and features of the
`Zope 2.12.8 <>`_ release.

Distribution changes

- Moved AccessControl, DocumentTemplate (incl. TreeDisplay) and
Products.ZCTextIndex to their own distributions. This removes the last direct
C extensions from the Zope2 distribution.

- Moved the ``zExceptions`` package into its own distribution.

- Drop the dependency on the ThreadLock distribution, by using Python's thread
module instead.

- Integrated the Products.signalstack / z3c.deadlockdebugger packages. You can
now send a SIGUSR1 signal to a Zope process and get a stack trace of all
threads printed out on the console. This works even if all threads are stuck.

Instance skeleton

- Changed the default for ``enable-product-installation`` to off. This matches
the default behavior of buildout installs via plone.recipe.zope2instance.
Disabling the persistent product installation also disabled the ZMI help

- Removed Zope2's own mkzeoinstance script. If you want to set up ZEO instances
please install the zope.mkzeoinstance and use its script.

- Removed deprecated ``read-only-database`` option from zope.conf.

- LP #143232: Added option to 'zope.conf' to specify an additional directory to
be searched for 'App.Extensions' lookups. Thanks to Rodrigo Senra for the

- LP #143604: Removed top-level database-quota-size from zope.conf, some
storages support a quota option instead.

- LP #143089: Removed the top-level zeo-client-name option from zope.conf, as it
had no effect since ZODB 3.2.

- Removed no longer maintained ``configure, make, make install`` related
installation files. Zope2 can only be installed via its

- Removed the unmaintained and no longer functioning ZopeTutorialExamples from
the instance skeleton.

Deprecated and Removed

- Finished the move of five.formlib to an extra package and removed it from Zope
2 itself. Upgrade notes have been added to the news section of the release

- ZPublisher: Removed 'Main' and 'Zope' wrappers for Test.publish. If anybody
really used them, he can easily use ZPublisher.test instead. In the long run
ZPublisher.test and ZPublisher.Test might also be removed.

- ZPublisherExceptionHook: Removed ancient backwards compatibility code.
Customized raise_standardErrorMessage methods have to implement the signature
introduced in Zope 2.6.

- Removed ancient App.HotFixes module.

- Removed the deprecated ``hasRole`` method from user objects.

- Removed deprecated support for specifying ``__ac_permissions__``,
``meta_types`` and ``methods`` in a product's ``__init__``.

- Remove remaining support classes for defining permissions TTW.

- Removed the deprecated ``five:containerEvents`` directive, which had been a
no-op for quite a while.

- Removed Products.Five.fivedirectives.IBridgeDirective - a leftover from the
Interface to zope.interface bridging code.

- Marked the ``<five:implements />`` as officially deprecated. The standard
``<class />`` directive allows the same.


- Completely refactored ``ZPublisher.WSGIResponse`` in order to provide
non-broken support for running Zope under arbitrary WSGI servers. In this
(alternate) scenario, transaction handling, request retry, error handling,
etc. are removed from the publisher, and become the responsibility of

- Moved the code handling ZCML loading into the ``Zope2.App`` package. The
component architecture is now setup before the application object is created
or any database connections are opened. So far the CA was setup somewhat
randomly in the startup process, when the ``Five`` product was initialized.

- Moved Products.Sessions APIs from ``SessionInterfaces`` to ``interfaces``,
leaving behind the old module / names for backward compatibility.

- Centralize interfaces defined in Products.ZCTextIndex, leaving BBB imports
behind in old locations.

- Moved ``cmf.*`` permissions into Products.CMFCore.

- Moved ``TaintedString`` into the new AccessControl.tainted module.

- Testing: Functional.publish now uses the real publish_module function instead
of that from ZPublisher.Test. The 'extra' argument of the publish method is no
longer supported.

- Moved ``testbrowser`` module into the Testing package.

- Moved general OFS related ZCML directives from Products.Five into the OFS

- Moved the ``absoluteurl`` views into the OFS package.

- Moved ``Products/Five/event.zcml`` into the OFS package.

- Moved ``Products/Five/`` and security related ZCML configuration
into the AccessControl package.

- Moved ``Products/Five/traversing.zcml`` directly into the configure.zcml.

- Moved ``Products/Five/i18n.zcml`` into the ZPublisher package.

- Moved ``Products/Five/publisher.zcml`` into the ZPublisher package.

- Ported the lazy expression into zope.tales and require a new version of it.


- Updated copyright and license information to conform with repository policy.

- LP #143410: Removed unnecessary color definition in ZMI CSS.

- LP #374810: ``__bobo_traverse__`` implementation can raise
