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 2.4.0
Bugs fixed
- Collector #2380: fixed regular expression in Converters.py
producing trash Control-M characters
- Collector #2379-2381: usage of map() inside PythonScripts
has been broken
- FTP download of large files was been broken. Fixed.
Zope 2.4.0 beta 3
Bugs fixed
- Collector #2219: no default for transaction_info in manage_
undo_transactions caused an error message if the undo button
was clicked without selecting any transactions to undo.
- Fixed breakage in the Zope tutorial cased by recent
Structured Text changes. Also made the tutorial better at
detecting if the tutorial examples have already been
installed or not.
- Fixed bug in bugfix for collector Structured Text doc_href bug.
- Fixed bug in z2.log username logging. Previous revisions
could result in a Zope which restarted unexpectedly.
Thanks to Richard Waid.
- Collector #2357: New attributes of string objects break some
existing dtml-in constructs. Now strings are not placed on
the namespace.
- Collector #2257: Renaming objects in the ZMI depended on
creating a new object and deleting the old object. Some user
code depended on this happening in such a way that the old
object remained around until after the new object was created.
The implementation now supports this. Thanks to stefan13.
- Collector #2256: Handling of broken objects / classes was
broken. Thanks Toby Dickenson!
- Collector #2334: Scripts (Python) that ended with an indented
line failed to compile. Thanks Butch Landingin!
- Collector #2266: Structured Text named link bug fixed.
- Collector #2251: Fixed bug with version numbers in distribution
tab.
- Fixed handling of invalid HTTP requests.
- Fixed several WebDAV locking problems (most related to Windows
webfolders and MS Office 2000)
- Collector # 2375: fixed broken 'Find' tab functionality
- Collector # 2363: The left menu of the ZMI is now updated when
using the import function.
- Collector # 2375: DateTime constructor was unable to handle unicode
strings.
Zope 2.4 beta 2
Bugs fixed
- Some of the import shenanigans in ZService.py were still
trying to load Python 1.5 versions of support dlls for running
as a service under win32 (meaning you effectively couldn't).
- Collector entries 2342 & 2348 - StructuredTextNG fixes.
Table-detection code used multi-arg appends and failed.
doc_href() method did not pick up on URLs with query strings.
Thanks to "datagrok"
- Collector #2335: older products like GadflyDA that did not
use registerClass() were registered but their visibility
flag has not been set to Global. So these products did not
appear in the ZMI.
- Corrected handling of nested scopes in restricted code.
The compiler did not correctly handle nested variables
used in multiple child scopes.
- added WebDAV workaround for MSIE 6 beta unable to handle accented
characters inside the CDATA section for the object properties
- fixed broken WebDAV support for GoLIVE unable to handle some
object properties placed inside CDATA sections
Zope 2.4 beta 1
Features Added
- Added a new lesson to the Zope tutorial which shows how to
insert data into a relational database.
- Made the meta-type in the upper-left corner of ZClass instances'
management interface into a link to the ZClass definition.
- Collector #2316: introduced new environment variable ZSYSLOG_FACILITY
to override the default syslog facility 'user'
Bugs fixed
- Updated the Zope tutorial a bit. Now it references the Zope
Book and the online help's DTML reference. Replaced ZopeTime
examples with DateTime in lesson 9.
- The manage_afterClone hook was called too early for copied objects,
before the cloned object was reattached to its context. This
caused problems with CatalogAware objects reindexing themselves
on copy.
- Fixed a situation that could slow down lazy processing of sorted
search results.
- Product import ordering has been changed. Now, the total set of
all Products are initialized in ascending alphabetical order by
product name, regardless of whether an INSTANCE_HOME exists.
If two products with the same name exist in both SOFTWARE_HOME
and INSTANCE_HOME, the order in which they appear in
Application.Products.__path__ determines whether they
are loaded first or second.
- Collector #2318: html_quote function re-aliased into
DT_Util so as not to break existing user code.
- Corrections to the code that adds interface information to the
meta type registry.
- Collector #2274: fixed typo in Transaction.py. Made Connection.py
a bit more noisy in case of failure
- Collector #2273: fixed bug in STXNG (unable to handle :img:
commands with absolute URLs)
- Collector #2272: fixed problem in Transaction.py (Objects
with id==None could not print themselves)
- fixed Python module import problems causing XML export/import
too be completely broken
- Collector #2270: fixed import problem when $INSTANCE_HOME
was set
- Collector #2269: default script for PythonScript is no longer
compiled during installation
- Updated to zlib 1.1.3.
- fixed parenthesis handling for TextIndex queries
- Collector #2283: PersistentMapping class keys() method now returns
a *copy* of the cached keys list instead of the cached list of
keys itself. This prevents mutation of the list.
- DateTime constructor now accepts ISO 8601 compliant dates
- Collector #2254: added hook for webdav/ftp MKCOL
- Collector #2247: put values of properties into CDATA section to
prevent non XML compliant documents to be sent to a webdav client.
- Collector #2287: fixed missing import of 'render_blocks' in
SendMailTag.py
- Collector #2289: leading \n\r inside messageText broke
mail headers
- Collector #2290: better handling of subject header in Mailhost.py
- Collector #2291: fixed cookie path in Zope Version Control
- Collector #2286: Could not create ZClasses. coptimizations.c
had been corrected erroneously. Fixed.
- It was discovered that the implicit names of certain DTMLMethods
were ambiguous, making security assertions for them unpredictable.
Code was added to detect the condition and correct it in the
Zope core. The affected DTML methods did not pose a security risk.
Instead, most were overprotective.
- "print" with a trailing comma (to avoid a newline) caused
spurious errors in Python Scripts. It turned out the compiler
module was in error. Fixed.
- Collector #2306: Fixed broken glossary of Zope Tutorial
- Collector #2305: A comma inside an optional parameter of the
parameter string broke the ZScriptHTML_tryParams function of
PythonScripts.
- Restored performance of security checks in DTML and
Scripts (Python) by replacing read guards with function calls to
guarded_getattr() and guarded_getitem() of ZopeGuards.
- Restricted the target of PythonScript print statements.
- Python 2.1 reopened the old "AttributeError: __call__" bug.
Checked in a fix that should finally solve it correctly.
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)
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.
