Zope Changes
This file contains change information for the current Zope release.
Change information for previous versions of Zope can be found in the
file HISTORY.txt.
Zope 2.4 alpha 1
Features Added
- Zope now requires Python 2.1. See the Zope 2.4 migration
document for details:
http://www.zope.org/Products/Zope/2.4.0/Zope24MigrationGuide.html
- The 'Authenticated' role has been added as one of Zope's
standard roles. A user's possession of this role indicates
that he or she has been authenticated by the Zope security
machinery. It is an implicit role, and cannot be provided to
users within the user management screens or the local roles
management screens. It is provided to all authenticated users.
Another way to think of the 'Authenticated' role is that
it is possessed by all users *except* the Anonymous User.
- A module 'requestprofiler.py' is now part of the utilities
directory. When run from the command line, this utility
allows you to generate profiling information from Zope's
detailed request log (the "-M" log).
- Restricted code can import AccessControl.getSecurityManager,
and use 'validate', 'validateValue', 'checkPermission',
'getUser', and 'calledByExecutable'.
- Zope's WebDAV support now includes exclusive write locking.
- Data.fs.in index_html now shows zope_quick_start instead
of old, inaccurate content.
- Changed index_html, standard_html_header, standard_html_footer,
and standard_error_message in Data.fs.in to use "new" DTML syntax
(as opposed to SSI-style syntax).
- Added check for 'FORCE_PRODUCT_LOAD' environ var to bits which
try to detect whether we're a ZEO client or not in order not to
skip product-loading tasks. This has the consequence that a ZEO
client with the "ZEO_CLIENT" env var set will cause product
loading tasks to occur iff his "FORCE_PRODUCT_LOAD" environment
var is set as well.
- Further optimizations in the lexicon of the Catalog as well
as the final merge code integration for Text indexes. This
should reduce the bloat when things are reindexed.
- StructuredText: old StructuredText replaces by StructuredTextNG.
Added support for locale settings. Several bugfixes and code
cleanup.
- Image and File objects now support the HTTP Range and If-Range
headers, enabeling partial downloads of such objects. This can be
used by clients to restart a broken download. Downloads of these
objects through FTP can also be restarted.
- Update of Medusa tree to latest version
- If an INSTANCE_HOME is defined and has a 'lib/python'
subdirectory, it will be added to the front of the Python path.
- DTML-In and DTML-Tree now have optional "prefix" attributes
that can be used to make friendlier tag variable names.
- Added product reloading capability, formerly provided by
the "Refresh" product. This enables developers to see the
effect of changes to their products without restarting Zope.
- Added new 'sequence' module for underscore namespace to provide
extended sorting functionality for sequence (implements
ExtendedDTMLSorting proposal)
- Fixed a long-standing bug in FileStorage that made it so
versions were only partially committed.
- Rewrote the complete indexing infrastructure according
to the DropinIndex proposal
(see lib/python/Products/PlugginIndexes/README.txt for
detailed informations).
- Adopted ZCatalog to new indexing infrastructure.
- added text() method to HTTPRequest object to provide a plain
text representation of the request (Collector #2264)
Zope 2.3.0 beta 3
Features Added
- Make ZClasses navigable to FTP/WebDAV; implement 'PUT_factory'
hook to create PythonScripts (for MIMEtype 'text/x-python')
and DTMLMethods (for other 'text' MIMEtypes) (Collector #998).
Bugs Fixed
- Mechanisms in the underbelly of the Catalog and Globbing
Lexicon (which is the default for all new Catalogs) has been
overhauled given substantial performance increases. On
simple queries, performance should double (or more) in many
situations, whereas with globbed queries it may increase by
substantially more.
Zope 2.3.0 beta 1
Features Added
- Added a hook that allows user folders to provide a logout
action.
- Added a browser preferences screen to allow people to
tweak the management UI to their liking. For the folks who
complained that they didn't like the new top frame, they
can (among other things) turn it off from the browser
preferences screen.
- Added Michel's new QuickStart material. I haven't quite
decided whether the old QuickStart should go away or
stay around as a source of examples.
- The logout function has been implemented in a fairly minimal
way. We may try to make this nicer by final if we get time.
- The ZCatalog interface is now cleaned up and matches the new
interface look and feel better. In addition some logical
reorganization was made to move things onto an Advanced tab.
- Result sets from the Catalog are now much Lazier, and will
do concatenation with eachother in a lazy fashion. This was
suggested by Casey Duncan in Collector #1712.
Bugs Fixed
- Added a deprecated alias to UnrestrictedUser, Super, for use
by user folder products that depend on the old class name.
- Fixed path for management interface files used for
CatalogPathAwareness and Aqueduct.
- Fixed a NameError in HTTPRequest.
- Made manage_page_style.css correctly available to all.
- ZCatalog objects now show up in the Add List in the same
naming convention that was used for all other Z* objects.
This does *not* affect the meta_type that is actually used
for the object itself.
- (Collector #1835, 1820, 1826) Eliminated errors in both
Field and Keyword indexes where old keys might show up in
'uniqueValuesFor()' because of the way the data structures
were kept around.
- (Collector #1823)Eliminated situation where if the Catalog
did not have a metadata record for 'meta_type' the Cataloged
Objects view would be incorrect and list everything as a
'ZCatalog'. Now it simply lists it as 'Unknown'.
- (Collector #1844) On the brains returned from ZCatalog
queries, 'getObject()' now tries to resolve URLs as well as
paths. This should catch more cases.
- Tags generated for ImageFile objects attempted to use
title_or_id(), which is not defined for those objects.
- Mounting now fails gracefully in when getId() is not
available in the mounted object.
Zope 2.3.0 alpha 2
Features Added
- The install machinery for source release has been modified
to allow Zope to build out of the box for Python 2.0. Note
however, that Python 2.0 is still not officially supported.
You may see quite a few warnings from the extension builder
when compiling for Python 2.
- A new module, AccessControl.Permissions has been added to
make it easier to use the new security assertion spelling.
The new module provides consistent symbolic constants for
the standard Zope permissions.
- Cache manager support added. This allows site administrators
to ease the burden on their site in a very configurable
way. It also provides an API for developers to follow when
experimenting with caching strategies.
- The ZPublisher 'method' form variable type has been
deprecated in favor of 'action'. The behavior is the
same, only the official (and documented in the Zope
book) name has changed. The 'method' name is still
supported for backward compatibility.
- The 'objectIds' and 'objectValues' methods of ObjectManager
derived objects are no longer directly Web-accessible. This
is a topic that has come up over and over on the lists. Some
(xml-rpc, mostly) users may depend on this behavior - applications
that need access to this information remotely should be modified
so that a Python Script or DTML Method can explicitly pass
the data.
- The Image.tag() and ZopeAttributionButton methods now return an
image tag that is XHTML compatible; a space and a slash have been
added.
- SQLMethods can now be edited via FTP and WebDAV tools. Thanks to
Anthony Baxter for his FTP support patches.
- The Catalog has been slightly overhauled to manage object
paths instead of URLs in its tables. This should not cause
any backward compatability concern, but everyone upgrading
should read the web pages on the zope.org site at:
http://dev.zope.org/Wikis/DevSite/Projects/ZCatalogVirtualHostFix/UpgradeFAQ
this will provide information about how to upgrade and new
features on the result sets, like getObject and
getPath. These are very important.
- SiteAccess 2.0 has been added, to enable virtual hosting.
- The StandardCacheManagers product has been added as a primary
product, making it easier to get started with caching.
- The class DTMLFile has been added alongside of HTMLFile.
It supports name bindings, ignores positional parameters,
and puts the container on top of the namespace by default.
Most HTMLFiles should work the same (or more securely) if
converted to a DTMLFile. Most management interface methods
should be converted by the final release of 2.3.
- Added a variable called PUBLISHED to REQUEST. From now on,
this variable should be used instead of PARENTS for user
validation.
- The inituser file is now read even when one user has been
created. This provides a way to reset the password after
a new user installs Zope but ignores the generated password.
- ZCatalogs have a reduced number of management interface tabs.
- ZCatalog keyword and field indexes have been modified to use
a merge strategy when existing indexes are updated. When an
existing object is indexed, the contents of field and
keyword indexes are merged with the changes detected between
the existing contents of the index and the new content.
- CatalogPathAware class added. This will eventually replace
CatalogAware.
- The ManagementInterfaceQuickFix project was merged in. The
Zope management interface has been tweaked in various ways
to improve productivity and consistency and is now at least
slightly less ugly :)
=======
>>>>>>> 1.310
Bugs Fixed
- TextIndexes which called methods expecting an argument failed
with a TypeError. This was fixed by extending an exception
handler.
- A security issue having to do with setting permission mappings
on ZClass methods was fixed (this supersedes Hotfix-2001-05-01)
- Automatic reloading of Help topics while running in debug mode
was fixed.
- Fixed problem adding propertynames with spaces (Collector #2206)
- Plugged a memory leak in extensions. There are often circular
references in code generated by Python's "exec" statement but
with a small change extensions now break those references.
- Hardened ZMI contents view against subobjects w/ flaky
'get_size' (Collector #1900).
- Fixed OFS.CopySupport's _verifyObjectPaste to utilize the
permission stored in the metatype registry, if available
(Collector #1975)
- Fixed a long-standing bug in FileStorage that made it so
versions were only partially committed.
