Software-update: Zope 2.8.5

Zope is een webapplicatieserver geschreven in de ontwikkeltaal Python en wordt uitgegeven onder de Zope Public License. Het beschikt onder andere over een transactional object database, dynamische HTML-templates, scripts, search engine en connecties naar relational databases. Het programma kan geheel zelfstandig gebruikt worden maar het is ook mogelijk om het aan andere programma's te koppelen, zoals Apache. De ontwikkelaars hebben de versie 2.8.5 vrijgegeven van Zope met de volgende veranderingen:

Hi all,

on behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.5. You can download the sources and the Windows version from here.

Some new features of Zope 2.8:
  • ZODB 3.4 with MVCC (multi version concurrency control) support. MVCC solves nearly every problem with ZODB read-conflict errors which is very important for high-traffic Zope sites.
  • Extension Classes were rewritten as Python new-style classes making all features of Python new-style classes available in Zope objects. This includes support for cyclic garbage collection.
  • Integration of Zope 3 technologies through Five (see
Bugs Fixed:
  • Collector #1976: FTP STOR command would load the file being uploaded in memory. Changed to use a TemporaryFile.
  • Collector #1904: On Mac OS X avoid a spurious OSError when zopectl exits.
  • CopySupport: Reverted workaround in _verifyObjectPaste. checkPermission now respects proxy roles, so the warkaround introduced to fix is no longer needed. Meta types listed in all_meta_types need a permission key.
  • Collector #1774: Harmonize the implementation of AccessControl.ZopeSecurityPolicy.checkPermission with validate, checking ownership and proxy roles if an executable object is on the stack.
  • AccessControl.SecurityInfo: Fixed problem with setPermissionDefault when the permission wasn't used anywhere else in the class to protect methods.
  • Collector #1957: Made ZPublisher.HTTPResponse._error_html return conformant XHTML.
  • Collector #1891: Backported changes to ZCatalog regression tests, removing use of whrandom (and its seed function).
  • Collector #1621, #1894: Added BBB alias for whrandom in AccessControl/ and RestrictedPython/ The alias will be removed in Zope 2.10.
  • Collector #1954: DocumentTemplate.DT_String: remove non-XHTML wart from error message.
  • Fixed unclear security declarations. Warn when an attempt is made to have a security declaration on a nonexistent method.
  • OFS Application: While deprecated since years, old-style product metadata in the did not show deprecation warnings. Added warnings and converted ZGadflyDA/ and ZSQLMethods/ to use registerClass instead.
  • The SiteErrorLog now copies exceptions to the event log by default.
  • ObjectManager now has an hasObject method to test presence. This brings it in line with BTreeFolder.
  • Made zopectl test work for software homes which do not have an "inplace" build (it used to require that be in $ZOPE_HOME/bin/; now it will use $ZOPE_HOME as a fallback).
  • Improved logging of ConflictErrors. All conflict errors are logged at INFO, with counts of how many occurred and how many were resolved. Tracebacks for all conflicts are logged a DEBUG level, although these won't help anyone much. If a conflict error is unresolved, it will now bubble up to error_log and standard_error_message.
  • Suppressed output of deprecation warning in filepath test for PythonScripts.
