Zope 2.8.6 (2006/02/25)

バグ修正

  • Collector #1819: 次のシグネチャを修正: MountedObject.SimpleTrailblazer._construct(
  • ZPublisher.BaseRequest: The publisher would happily publish attributes of type ‘bool’ and ‘complex’, as well as Python 2.4’s ‘set’ and ‘frozenset’.
  • Collector #1991: ZPublisherが%20で終わっているURLを適切に対処 していませんでした。
  • Collector #2013: エラーメッセージのXHTML適応度を高めました。 いくつかの<p>タグが閉じていませんでした。
  • Collector #1999: FTPにおける名前変更機能の不具合を修正しました。 (RNFRはステータスコード250ではなく350を返すようになりました)
  • Collector #2002: ls -R 機能の不具合を修正しました。 (OFSフォルダのサブクラスで再起処理が行われていませんでした)

Zope 2.8.5 (2005/12/19)

バグ修正

  • Collector #1939: When running as a service, Zope could potentially collect too much log output filling the NT Event Log. When that happened, a ‘print’ during exception handling would cause an IOError in the restart code causing the service not to restart automatically.

    Problem is that a service/pythonw.exe process always has an invalid sys.stdout. But due to the magic of buffering, small “print” statements would not fail - but once the file actually got written to, the error happened. Never a problem when debugging, as the process has a console, and hence a valid stdout.

  • 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 http://www.zope.org/Collectors/Zope/78 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/DTML.py and RestrictedPython/Utilities.py. 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 __init__.py did not show deprecation warnings. Added warnings and converted ZGadflyDA/__init__.py and ZSQLMethods/__init__.py to use registerClass instead.

その他の変更

  • 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 test.py 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.

Zope 2.8.4 (2005/10/26)

バグ修正

  • Collector #1927: Modified ZReST not to store rendered / warnings as persistent attributes, using volatile attributes instead as a cache.
  • Collector #1926: fixed a typo in _doAddUser when password encryption is enabled.
  • If a content object implemented any in-place numeric operators, untrusted code could call them, thus modifying the content.
  • If Python 2.4 is used, despite the fact that Python 2.4 is unsupported, untrusted code could use generator expressions to gain access to container items.

Zope 2.8.3 (2005/10/18)

その他の変更

  • ZSQLMethod.manage_main: Moved the error message that warns of a non-existing or closed database connection next to the Connection ID dropdown and present it using red to increase its visibility.
  • Update to Docutils 0.3.9 (forgotten in Zope 2.8.2)

Zope 2.8.2 (2005/10/13)

機能追加

  • Collector #1118: Added syntax to dtml-sqlgroup to support flexible generation of ‘UPDATE’ statements (bounty sponsored by Logicalware).
  • The ‘@’ character is now allowed in object ids (RFC 1738 allows it).

バグ修正

  • OFS.Image.manage_FTPget() would str() it’s .data attribute, potentially loading the whole file in memory as a string. Changed to use RESPONSE.write() iterating through the Pdata chain, just like index_html().
  • When PageTemplates have a syntax error, show the traceback output in the rendered error message.
  • Collector #1914: Hardened ‘call_with_ns’ (in ‘Products.PageTemplates.ZRPythonExpr’) against namespaces from other callers than page templates.
  • Collector #1490: Added a new zope.conf option to control the character set used to encode unicode data that reaches ZPublisher without any specified encoding.
  • Collector #1895: omit ‘var’ folder from recursive traversal causing trouble with DirectoryStorage.
  • disabled ”.. include” directive for all the ZReST product and the reStructuredText package
  • Collector #1888: Adjust call to ‘engine.translate’ to accomodate change in its signature.
  • Collector #1863: Prevent possibly sensitive information to leak via the TransientObject’s __repr__ method.
  • Repaired ‘handle_errors’ usage for doctests, along with the supporting ‘debug’ argument passed to ‘ZPublisher.Test.publish_module’.
  • Collector #1879: applied patch by Dieter Maurer to fix a bug in ac_aquire() ignoring the default argument
  • Collector #1864, #1906: fixed header normalization in appendHeader()
  • Collector #1899: fixed migration issue when using export/import for ZCatalog instances
  • ‘ZPublisher.Test.publish’ now takes a ‘done_string’ argument, which is written to standard error when the request completes (forward ported from Zope 2.7 branch).
  • Collector #556: <dtml-sqlvar> now returns ‘null’ instead of ‘None’ for values which are None in Python (sponsored by a bounty from Logicalware).
  • Collector #1182: BBB Forward port fix from 2.7 branch (19 months ago!), reverting ‘guarded_getitem’ to pass the ‘index’ argument as the name to ‘validate’. This change is not propagated to the trunk, because the resolution of #1182 specifies that the reverted behavior (i.e., passing None for item accces) is to become the standard implementation as of 2.9.
  • Collector #1877: skel/Products/README.txt inappropriately copied from CMF.
  • Collector #1871: Applied patch to support lists with records using ZTUtils.make_query()
  • AccessControl: creating a new user through “zpasswd inituser” did not work properly with a top-level user folder with enabled password encryption.
  • ZCatalog: refreshCatalog() could not be called safely from a ZEO client script
  • Catalog.clear(): fixed handling of _length attribute (caused import problems for some .zexp files e.g. Squishdot instances)
  • DateIndex now properly removes documents from both indexes if the value is None
  • Collector #1888: Some parts of the TALInterpreter would not pass a default when translating, yet expect a string back. This would cause an error (usually “NoneType has no attribute ‘replace’”) in the case the message was not translated.

Zope 2.8.1 (2005/08/11)

機能追加

  • Interface: Added Z3 -> Z2 bridge utilities. This allows to migrate interfaces to Zope 3 style interfaces and bridge them back to oldstyle interfaces for backwards compatibility.

バグ修正

  • Zope2.Startup.zopectl: fork before execv when running unit tests (don’t exit the shell, if run from there).
  • TAL: MassageIDs are now handled the same way as in zope.tal.
  • DocumentTemplate: ustr no longer mangles MassageIDs. Custom string types are now returned unchanged.
  • As developed in a long thread starting at http://mail.zope.org/pipermail/zope/2005-July/160433.html there appears to be a race bug in the Microsoft Windows socket implementation, rarely visible in ZEO and/or in ZServer/medusa/thread/select_trigger.py when multiple processes try to create an “asyncore trigger” simultaneously, most often (in stress tests) manifesting as a hung process. Windows-specific trigger code in both changed to work around this bug when it occurs.
  • Collector #1807: fixed memory leak in cAccessControl.guarded_getattr()

Zope 2.8.1 b1 (2005/07/28)

機能追加

  • PluginIndexes, ZCTextIndex and ZCatalog: Added some z3 interfaces.
  • Verbose security exception reporting has been folded into Zope, removing the need for the VerboseSecurity product. See the documentation for the “verbose-security” option in zope.conf.
  • “TemporaryStorage” (the storage that is used mainly to back the default sessioning database) is now MVCC capable, which essentially means that its usage will no longer generate ZODB ReadConflictErrors.

バグ修正

  • Collector #1852: fixed wrong URL construction in webdav.davcmds
  • Collector #1844: fixed whitespace handling in the ZMI “Find” tab
  • Collector #1813: removed spurious inclusion of CMFBTreeFolder. in Products/BTreeFolder2 (CMFCore will include it after 1.5, with an appropriate module alias for backward compatibility).
  • Replaced all transaction.commit(1) calls by transaction.savepoint()
  • Collector #1832: UnIndex swallowed ConflictErrors.
  • Collector #1815: ZCTextIndex accepts (again) sequences of strings to be indexed.
  • Collector #1812: Fixed key error in ZSQL ZMI/Test
  • Fixed CMFBTreeFolder for CMF 1.5+
  • WebDAV COPY and MOVE did not call ‘_notifyOfCopyTo’ and ‘_postCopy’ hooks like it was done in OFS.CopySupport. Additionally added ‘manage_changeOwnershipType’ to make MOVE behave even closer to OFS.CopySupport.
  • Collector #1548: Fix ‘httplib’ usage in ZPublisher.Client.
  • Collector #1808: manage_convertIndexes no longer tries to change the index types causing some trouble with CMF.
  • manage_convertIndexes did not treat DateRangeIndexes and PathIndexes properly.
  • Updated Zope X3 to bugfix release 3.0.1
  • Updated Five to bugfix release 1.0.2 (see Products/Five/CHANGES.txt)

Zope 2.8.0 (2005/06/11)

バグ修正

  • Collector #1792: applied patch for broken ZClasses
  • doc/FAQ.txt updated: should bear some resemblance to reality now. (PCGI stuff removed; error information updated; PID information updated; upgrade procedure added; some common version questions added.)
  • Collector #1770: Fixed RestructuredText subtitle
  • Collector #1803: Fixed InitializeClass for some corner case.
  • Collector #1798, issue 1: ZopeTestCase no longer tries to install products that were installed by Zope during startup.
  • Collector #1799: Avoid lying about parent’s refcount when calling back into Python code.
  • Collector #889: made ‘and’ operator for KeywordIndexes actually restrict results as expected (thanks to ‘aroda’ for the patch!).
  • Collector #1323: applied patch to fix umask problem in zdctl
  • Updated Five to bugfix release 1.0.1 (see Products/Five/CHANGES.txt)

Zope 2.8.0 b2 (2005/05/22)

機能追加

  • Made WebDAV server distinguishable from the default HTTP server both in the ZMI and in event.log.
  • Made Acquisition and derived classes play inside Python’s acyclic garbage collection framework.
  • Included BTreeFolder2

バグ修正

  • Collector #1507/1728: Server addresses are now handled the same way on all platforms. This fixes the default binding on Windows.
  • Collector #1781: made ‘create_mount_points’ ZConfig option actually work (thanks to Dieter Maurer for the patch).
  • Collector #1780: DateTime.strftime() now handles dates <= 1900 or >= 2038
  • Collector #1775: turning off debug mode by default
  • Collector #1784: fixed handling of multiple attributes in ZCTextIndex
  • Don’t copy ‘.svn’ directories from skeleton into an instance (thanks to Dale Hirt for the patch).
  • Collector #1776: Improved setup.py. The Finder class is now used for the complete lib/python tree and has a blacklist instead of a whitelist for file extensions. So there should no longer be a need to update setup.py if modules or files are added or removed in lib/python.
  • Collector #1751: Improved error reporting reporting during the startup phase
  • Collector #1745: Fixed ZSQL error KeyError ‘query’
  • Collector #1735: fixed UnicodeDecodeError in Loader.py

Zope 2.8b1 (2005/04/24)

機能追加

  • Added lazy: TAL expression and fixed defer: expression for python expression
  • ZCatalog.CatalogBrains: An _unrestrictedGetObject method has been added.
  • ZODB transactions now support savepoints. See transaction/savepoint.txt. These will replace subtransactions.

バグ修正

  • Collector #1754: Fixed import of ‘transaction’ in ‘zopectl adduser’ (which wasy dying with a NameError).
  • Collector #1750: StructuredText: fixed handling of image URLs with query string
  • Collector #1748: Fixed SIGSEGV in Acquisition
  • Hotfix_20050405: classes defined in untrusted code could shadow the roles of methods defined as protected by their bases.
  • Collector #1656: Fixed enumeration within untrusted code (forward-port from 2.7 branch).
  • Collector #1721: Fixed handling of an empty indexed_attrs parameter

Zope 2.8a2 (2005/04/02)

機能追加

  • ZCatalog.CatalogBrains: ‘getObject’ now raises errors, rather than returning None, in cases where the path points either to a nonexistent object (in which case it raises NotFound) or to one which the user cannot access (raising Unauthorized). Sites which rely on the old behavior can restore setting a new zope.conf option, ‘catalog-getObject-raises’, to “off”.

    This compatibility option will be removed in Zope 2.10.

  • PluginIndexes: the ZCatalog’s “Indexes” tab now show the number of distinct values indexed by each index instead of a mixture of indexed objects versus number of distinct values. Indexes derived from UnIndex show both values within their own ZMI screen. In addition most indexes have now a “Browse” tab to browse through the list of indexed values and their occurrences.

  • FTPServer: a RNFR (rename from) request is now being responded with a 550 error code if the source file does not exist

  • Fixed ObjectManager to not swallow exceptions during object deletion (in debug mode and if the user is not Manager). This allows for better debugging, while still keeping the possibility for a Manager to delete buggy objects.

  • Added a ZConfig directive ‘large-file-threshold’ to control the request content-size threshold at which a temporary file gets created. Use the same value for deciding between reading the whole request in memory or just a chunk inside webdav.NullResource.PUT().

  • RAMCacheManager: Allow invalidation of a cache entry from the Statistics view in the ZMI

  • Collector #1454/OFS.File: Accept content types ending with “javascript” as editable through the File edit form, just like text/<foo> types

  • Zope X3 3.0.0’s ‘src/zope’ package is included now.

  • Five (Zope 3 integration technology for Zope 2) is included now in Products/Five.

バグ修正

  • Collector #1460: guarded_apply was too restrictive.
  • OFS.Traversable still used a string ‘NotFound’ exception.
  • ZPublisher would fail to recognize a XML-RPC request if the content-type header included a ‘charset’ parameter.
  • Forward-ported ‘aq_acquire’-related fix and associated tests from Zope 2.7.4.
  • Collector #1730: XML page templates couldn’t call aq_parent in path expressions.
  • Fixed brain.getObject() to correctly traverse to an object even if one of its parents is not accessible, to be close to what the Publisher does.
  • Forward ported fix for OFS.CopySupport tests which corrected signature of a faux security policy’s ‘validate’ method.
  • ‘setup.py’ did not install the ‘Zope’ compatibility module (the old ‘Zope’ package has been renamed to ‘Zope2’).
  • Fixed Shared.DC.ZRDB.Results to behave with the new-style ExtensionClass. Added a test.
  • ‘setup.py’ did not install the new ‘Zope’ compatibility module (the ‘Zope’ package has been renamedd to ‘Zope2’).
  • Collector #1507: Zope now binds again to all available IP addresses if ip-address is unset
  • Use ‘del’ instead of ‘list.remove()’ in Catalog.delColumn(). There can be only one column with the same name, and it could potentially break catalog metadata as remove() may remove more than one element from the list if they have the same value. Also, we already have the list index we are interested in deleting so it doesn’t make sense to look up the value and call ‘list.remove()’ on it.
  • Collector #1628: FTP server has been broken (directory listings did not work)
  • Collector #1705: CopySource._postCopy is never called
  • Collector #1617: Fixed crash in ZPT code (caused by improper checks in cAccessControl)
  • Collector #1683: fixing batching in the DA “Test” tab
  • Collector #1648: Fix bug in Medusa FTP
  • Collector #1667: allow ‘max-number-of-session-objects 0’ to have the same effect as setting the value via the web interface (i.e., make the number of session objects unlimited, rather than falling back to the default).
  • Collector: #1651: removed compiler warning
  • Collector #1661: make ‘python-check-interval’ setting in zope.conf actually work as documented. This setting allows for important tuning opportunities for production Zope servers.
  • Collector #1657: Don’t break host-based virtual hosting when purging an HTTP accelerator.
  • DTML Methods were not interoperable with the new filestream_iterator and caches based on it (FileCacheManager).
  • Collector #1655: fixed severe memory leak in TemporaryStorage
  • Collector #1407: fixed XML escaping problem introduced in 2.7.4 b1
  • Collector #1151: HTTP compression was broken on error pages
  • The REQUEST now contains a new entry ACTUAL_URL which contains the full URL without query string as it appears within the location bar of the browser. The key has been added to provide a single key that is available for vhosted and non-vhosted installations.
  • Collector #1605: VHM did not quote URLs
  • webdav.Resource: during COPY, manage_afterClone was called way too early, thus the object wasn’t bound to the database and couldn’t find a context. Changed to behave the same way as CopySupport.
  • RAMCacheManager: opimized performance by using cPickle instead of pickle and by using the highest pickle protocol available instead of using ASCII pickles (patch by Dieter Maurer)
  • Collector #631: Image URLs in StructuredText containing port numbers were not rendered correctly
  • Collector #1498: Don’t choke on malformed cookies. Cookies of the form “foo=bar; hmm; baz=gee” will give an empty value for ‘hmm’ instead of silently discarding it and the rest of the string. (Thanks to ‘sirilyan’ for the patch.)
  • bin/zopectl test now uses os.execv, instead os os.system, so that options with characters that needs shell quoting doesn’t break the command.
  • Collector #1219: Make XML export sane again.
  • Collector #945: Allow adding empty PythonScript instances programmatically.
  • Updated doc/UNITTEST.txt and lib/python/Testing/README.txt to reflect progress made since UNITTEST.txt was originally written.
  • Removed Version objects from the add menu. Versions are agreed to be a feature that should not be used as it is not well implemented and allows for data loss.
  • Collector #1510: Allow encoding of application/xhtml+xml pages according to the charset specified in the Content-Type header (thanks to Jacek Konieczny for the patch).
  • Collector #1599: made sqltest work with unicode strings (thanks to Peter Sabaini for the patch).
  • zopectl: fixed handling of child processes (patch by Dieter Maurer)
  • Collector #1593: fixed dumb _get_id() implementation in OFS.CopySupport that produced copy_of_copy_of....files (thanks to Alexandre Boeglin for the patch).
  • Collector #1450: files in utilities/ZODBTools are now installed during the installation process in the ‘bin’ directory
  • Collector #1003: added new ‘http-header-max-length’ directive to zope.conf to specific the maximum length of a HTTP request header before it is considered as a possible DoS attack and discarded.
  • Collector #1371: added new ‘cgi-maxlen’ directive to zope.conf to limit the amount of form data being processed by Zope to prevent DoS attacks
  • Collector #1407: changed WebDAV display name for objects to title_or_id()
  • the ‘trusted-proxy’ directive in zope.conf now also accepts hostnames instead of IP addresses only (patch by Dieter Maurer)
  • Fixed test.py to not over-resolve symbolic links. Needed to run tests when the Products directory and a product are symlinks.
  • Collector #1583/ZReST: Fixed handling of the title attribute for non-ascii characters.
  • Collector #1577: Fixed cryptic error message in ZPublisher if a non-ASCII string is passed to a date, int, long or float property.
  • Collector #1576: Fixed Z Search Interface to use proper HTML.
  • Collector #1127: strftime did not take timezone into account.
  • Collector #1569/DateTime: Added a new ISO8601-method that will return correctly formatted ISO 8601-representations to augment the ISO method which isn’t compliant with ISO 8601.
  • ZPublisher: changed some hardcoded ‘latin1’ arguments to ‘iso-8859-15’ since latin1 is obsolete.
  • Collector #1566: Installation of Zope on some older Solaris versions could fail due to a broken “echo” implementation causing the creation of a borked version.txt file.
  • Collector #934: Image and File objects are now always internally split into small chunks even when initialized from a string.
  • docutils: updated to V 0.3.5. The Zope core now contains a full copy of the docutils package except some GPLed files which can not be included with the Zope distribution due to license constraints on svn.zope.org.
  • docutils: moved from lib/python/docutils to lib/python/third_party/docutils
  • Collector #1557/OFS.Image: Introducing new ‘alt’ property. The ‘alt’ attribute is no longer taken from the ‘title’ property but from the new ‘alt’ property. The border=”0” attribute is no longer part of the HTML output except specified otherwise.
  • Set a default value of ‘’ for the new ‘alt’ property as not to break existing content.
  • Collector #1511: made IPCServer show up in the Control Panel under “Network Services”
  • Collector #1443: Applied patch by Simon Eisenmann that reimplements the XML parser used in WebDAV fixing a memory leak.
  • Always unescape element contents on webdav.xmltools
  • Use saxutils to escape/unescape values for/from PROPFIND/PROPPATCH.
  • Make OFS.PropertySheet use the escaping function from webdav.xmltools.
  • Escape/unescape &quot; and &apos;
  • Don’t escape properties stored as XML (ie: having a __xml_attrs__ metadata set by PROPPATCH) when building a PROPFIND response.
  • If a PROPPATCH element value contains only a CDATA section, store the CDATA contents only.
  • Catch AttributeErrors and KeyErrors raised from __bobo_traverse__ and convert them to NotFound. In debug mode a more verbose error message is issued, the same way it’s done on attribute/item traversal.
  • Collector #1523: replace the text field for importing .zexp/.xml files with a selection list
  • Stitch newly-created object into it’s container before calling it’s PUT() method. This fixes an issue with OFS.File/OFS.Image that would result into reading the whole file in memory and wrapping it into a single Pdata object.
  • Import ZServer.CONNECTION_LIMIT variable inside the method that uses it. Before this, the variable was imported at the module level, thus binding it too early which would cause the ZConfig handler to have no real effect.

Zope 2.8a1 (2004/10/17)

機能追加

  • Included Stefan Holek’s ZopeTestCase 0.9

  • The SiteErrorLog allows you to acknowledge (or delete) exceptions, so you can reduce or clear the list without restarting your Zope server. Additionally the SiteErrorLog is covered by unit tests now.

  • Unit tests added for the SiteErrorLog.

  • UI improvement for the ZCatalog. The “catalog contents” allow you to filter the cataloged objects by path now.

  • Made test.py follow symbolic links on POSIX systems.

  • added utilities/reindex_catalog.py to perform ZCatalog maintenance operations from the command line (through zopectl)

  • RESPONSE.setBody and RESPONSE.setStatus now accept lock parameters in the same way as RESPONSE.redirect. These prevent further calls to the methods from overwriting the previous value. This is useful when writing http proxies.

  • DateTime: new DateTime instance can be constructed from a given DateTime instance: d_new = DateTime(d_old)

  • The DateTime parser now throws a SyntaxError upon any parsing errors.

  • ZCatalog: added a new configuration option in the “Advanced” tab to provide optional logging of the progress of long running reindexing or recataloging operations.

  • made Zope.configure return the starter instance to enable other methods to be called, such as starter.setupConfiguredLoggers()

  • Improved Unicode handling in Page Templates. Template contents and title will now be saved as a Unicode string if the management_page_charset variable can be acquired and is true. The character set of an uploaded file can now be specified.

  • zopectl now accepts the -m argument to set a umask for files created by the managed process (e.g. -m 002 or –umask 002).

  • AccessControl/permission_settings() now has a new optional parameter ‘permission’ to retrieve the permission settings for a particular permission.

  • The obsolete ‘SearchIndex’ package has been removed

  • Traversal now supports a “post traversal hook” that get’s run after traversal finished and the security context is established.

  • Using “_usage” parameters in a ZCatalog query is deprecated and logged as DeprecationWarning.

  • MailHost now has two additional properties, a user id and a password. These are used to attempt ESMTP authentication before sending a mail.

  • Folder listings in FTP now include ”.” as well as ”..”.

  • When a VHM is activated, it adds the mapping ‘VIRTUAL_URL_PARTS’: (SERVER_URL, BASEPATH1, virtual_url_path) to the request’s ‘other’ dictionary. If BASEPATH1 is empty, it is omitted from the tuple. The joined parts are also added under the key ‘VIRTUAL_URL’. Since the parts are evaluated before traversal continues, they will not reflect modifications to the path during traversal or by the addition of a default method such as ‘index_html’.

  • Extension Classes, a key Zope foundation, have been totally rewritten based on Python new-style classes.

    This change provides a number of advantages:

    • Use of new-style class features (e.g. slots, descriptors, etc.) in Zope objects. Support for object protocols (special __ methods) added since Python 1.4.
    • Support for cyclic garbage collection.
    • Ability to use new-style classes as base classes of Zope objects.
    • Pave the way for sharing code between Zope 2 and Zope 3.

    Note – Extension classes with __of__ methods are made into Python read descriptors.

    If an extension classes is used to implement a descriptor, indirectly by implementing __of__ or directly by implementing __get__, the behavior of the descriptor will differ from ordinary descriptors in an important way. The descriptors __get__ method will be called even if the descriptor is stored on an instance of an extension class. Normally descritor __get__ methods are called only of the descriptor is stored in a class.

  • ZODB 3.3

    This is the first version of ZODB that does not require ExtensionClass.

  • Add ‘parity’ method to ZTUtils Iterators.

  • Allow untrusted code to mutate ZPublisher record objects.

  • Added a “mime-types” configuration value which names a file giving additional MIME type to filename extension mappings. The “mime-types” setting may be given more than once in the configuration file; the files have the same format at the mime.types file distributed with Apache.

  • Changed the ZEO server and control process to work with a single configuration file; this is now the default way to configure these processes. (It’s still possible to use separate configuration files.) The ZEO configuration file can now include a “runner” section used by the control process and ignored by the ZEO server process itself. If present, the control process can use the same configuration file.

  • ZConfig was updated to version 2.0. The new version includes two new ways to perform schema extension; of particular interest in Zope is the ability for a configuration file to “import” new schema components to allow 3rd-party components (such as storages, databases, or logging handlers) to be used.

  • The testrunner.py script has been replaced with test.py which is now installed into the ‘bin’ folder.

バグ修正

  • Removed Python 2.3.3 as valid option. ZODB 3.3 requires Python 2.3.4 or later.
  • Collector #1332: Added in-place migration of the Catalog.__len__ attribute to avoid new-style class caching problems. Instances of ZCatalog or instances of classes with ZCatalog as base class will be migrated automatically. Instances of Catalog or classes with Catalog as base class must be migrated manually by calling the migrate__len__() method on the every instance. In addition old BTree migration code (for pre-Zope 2.5 instances) has been removed. If you want to migrate from such an old version to Zope 2.8, you need to clear and reindex your ZCatalog).
  • Collector #1595: same as in Collector #1132 for indexes derived from UnIndex. Exisiting ZCatalog instances must be converted manually by calling the “manage_convertIndexes” method through-the-web for every single ZCatalog instance. See also doc/FAQ.txt (Installation, question #4)
  • Collector #1457: ZCTextIndex’s QueryError and ParseError are now available for import from untrusted code.
  • Collector #1473: zpasswd.py can now accept –username without –password
  • Collector #1491: talgettext.py did not create a proper header for the generated .pot file if multiple pagetemplate files were processed.
  • Collector #1477: TaintedString.strip() now implements the same signature as str.strip()
  • TAL: tal:on-error does not trap ConflictError anymore.
  • OFS.CopySupport: Enforced “Delete objects” permission during move (CMF Collector #259).
  • Removed DWIM’y attempt to filter acquired-but-not-aceessible results from ‘guarded_getattr’.
  • Collector #1267: applied patch to fix segmentation faults on x86_64 systems
  • ZReST: the charset used in the rendered HTML was not set to the corresponding output_encoding property of the ZReST instance. In addition changing the encodings through the Properties tab did not re-render the HTML.
  • Collector #1234: an exception triple passed to LOG() was not propagated properly to the logging module of Python
  • Collector #1441: Removed headers introduced to make Microsoft webfolders and office apps happy, since they make a lot of standards-compliant things unhappy AND they trick MS Office into trying to edit office files stored in Zope via WebDAV even when the user isn’t allowed to edit them and is only trying to download them.
  • Collector #1445: Fixed bad interaction between -p and -v(v) options to test.py that resulted in exceptions being printed when they shouldn’t have been.
  • Collector #729: manage_main doesn’t display the correct page title most of the time. It is not completely fixed but using title_or_id makes folders display the correct id as a fallback.
  • Collector #1370: Fixed html generated by Z Search interface.
  • Collector #1295: Fixed minor niglet with the Elvis tutorial.
  • added “version.txt” to setup.py to avoid untrue “unreleased version” messages within the control panel

  • Collector #1322: fixed HTML quoting problem with ZSQL methods in DA.py
  • Collector #1124: The ZReST product now uses the same reST encoding parameters from zope.conf as the low-level reStructuredText implementation.
  • Collector #1259: removed the “uninstall” target from the Makefile since the uninstall routine could also remove non-Zope files. Because this was to dangerous it has been removed completely.
  • Collector #1299: Fixed bug in sequence.sort()
  • Collector #1159: Added test for __MACH__ to initgroups.c so the initgroups method becomes available on Mac OS X.
  • Collector #1004: text,token properties were missing in PropertyManager management page.
  • Display index name on error message when index can’t be used as ‘sort_on’.
  • PUT would fail if the created object had a __len__ = 0 (eg: BTreeFolder2) and fallback to _default_put_factory. Fix by checking if the returned object is None instead.
  • Collector #1160: HTTPResponse.expireCookie() potentially didn’t when an ‘expires’ keyword argument was passed.
  • Collector #1289: Allow ZSQL methods to be edited via WebDAV.
  • WebDAV property values were not being properly escaped on ‘propstat’.
  • WebDAV ‘supportedlock’ was not checking if the object did implement the WriteLockInterface before returning it’s value.
  • reStructuredText ignored the encoding settings in zope.conf

  • App.config.setConfiguration() did not update the legacy source for debug_mode, Globals.DevelopmentMode.
  • Script (Python) objects now have a _filepath attribute, also used as the ‘__file__’ global at runtime. This prevents an import problem caused by the fix to #1074.
  • Minor usability tweaks:
    • Increased FindSupport meta type selection widgets height to 8 lines
  • The DateTime module did not recognize the settings for “datetime-format”.
  • Stop testrunner.py from recursing into the ‘build-base’ directory created by setup.py.
  • Collector #1074: Change Scripts’ __name__ to None
  • Range searches with KeywordIndexes did not work with record-style query parameters
  • Item_w__name__ now has a working getId() method
  • PageTemplateFile now using Item_w__name__ mixin, fixing its getId() and absolute_url() methods.
  • Only one VirtualHostMonster is allowed per container.
  • Collector #1133: TreeTag choked on Ids of type long.
  • Collector #1012: A carefully crafted compressed tree state could violate size limit. Limit is no longer hardcoded.

  • Management interface of TopicIndexes has been completely broken
  • Collector #1129: Improper parsing of ISO8601 in DateTime.
  • Removed pervasive use of string exceptions (some may still be hiding in the woodwork, but all raise’s with string literals are gone).
  • AccessControl.User used a misleading string exeception, ‘NotImplemented’, which shadowed the Python builtin.
  • Collector #426: Inconsistent, undocumented error() method.
  • Collector #799: Eliminate improper uses of SCRIPT_NAME.

  • Made the control panel properly reflect the cache-size setting of ZODB’s object cache once again.
  • ConflictError was swallowed in ObjectManager by manage_beforeDelete and _delObject. This could break code expecting to do cleanups before deletion.
  • Python 2.3 BooleanType wasn’t handled properly by ZTUtils marshalling and ZPublisher’s converters.
  • Collector #1065: bin/ scripts didn’t export HOME envars.
  • Collector #572: WebDAV GET protected by ‘FTP Access’ permission. Two new methods have been added to WebDAV resources, “manage_DAVget” and “listDAVObjects”. These are now used by WebDAV instead of the earlier “manage_FTPget” and “objectValues”. This separates the permissions, and allows WebDAV specific overriding of these methods.
  • Collector #904: Platform specific signals in zdaemon/Daemon.py (fixed by removing the “fossil” module from 2.7 branch and head).
  • Workaround for Collector #1081: The ‘title’ property for objects derived from OFS.Folder or PropertyManager can now be removed and replaced with a ustring property. This allows the usage of non-ISO-8859-1 or ASCII charsets

  • Collector #851: Traversable.py: A bare try..except shadowed conflict errors
  • Collector #1058: Several fixes for PropertySheets when used outside ZClasses
  • Collector #1053: parseIndexRequest turned empty sequence of search terms into unrestricted search.
  • manage_tabs had a namespace problem with the acquisition of names from the manage_options variable resulting to acquire “target” and “action” from objects above in the hierachy.
  • PathIndex and TopicIndex are now using a counter for the number of indexed objects instead of using a very expensive calculation based on the keys of their indexes.
  • Collector #1039: Whitespace problem in Z2.log fixed
  • changed some bare try: except:’s in Shared.DC.ZRDB.Connection so that they now log exceptions that occur.
  • ObjectManager will now attempt to set Owner local role keyed to the user’s id, rather than username.
