Zope Installation Frequently Asked Questions
--------------------------------------------
Installing Zope
1. On certain Unix platforms (usually Solaris) I get a "checksum
error" untarring the Zope distribution. Whats the deal?
Zope is built and distributed using GNU tar. Some vendor-supplied
tar implementations have problems with long path names as they
appear in GNU tar created files. This is a problem that occurs in
a number of software distributions created using GNU tar, not just
Zope. We suggest that you install a GNU tar on your system to
avoid this problem (not just with Zope, but with other software
distributions as well).
2. I am trying to build Zope on my BSD based system, but I
keep getting "symbol not found" errors and the build
scripts stop. What do I do?
On some BSD based systems (BSDI, BSD/OS), you need to edit
the Makefile.pre.in files in your Zope installation to add
-rdynamic to the LDSHARED makefile variable. On some systems
it may also be necessary to change the file named 'do.py'
located in the 'inst' directory of your Zope installation,
changing the line: do('make') to: do('make -k').
3. I am having trouble building Zope on my OpenBSD system. I get
some weird compilation errors.
Make sure you unpack Zope using GNU tar; you will not get any
error messages with OpenBSD's standard tar, but your installation
will be subtly broken due to problems with long path names.
4. I am having trouble building Zope on a libc 5 Linux machine.
Zope requires Python be built with glibc 2.x (libc 6) on Linux.
5. I am trying to install Zope on a Windows NT/2000 machine, but
I keep getting a dialog saying "corrupt installation detected".
Is something wrong with the distribution file?
No, to install Windows NT / 2000 you should be logged in with
"Administrator" privileges on the machine. If you are seeing
the "corrupt installation detected" dialog, you probably don't
have the required administrator privileges (your guess is as
good as ours as to why you get that particular error message).
Starting/Accessing your Zope installation
1. After installing Zope, I go to the URL in my web browser
but I get a "404 Not Found" or "Server Error" message
Is the URL really correct? Are you running Zope behind another
web server? If so, this message is coming from your web server,
not Zope. It usually means that your web server is misconfigured.
Look in the error log for your web server for details of the error.
2. I have installed Zope, and when I go to the URL in my web
browser, I get a password prompt. Although I type in the correct
username and password, I keep getting prompted. What is going on?
Are you running another web server in front of Zope?
Zope manages access control internally, but it relies on your
web server software to relay any authentication information in
web requests. Some web servers automatically filter this information
out of requests passed to cgi programs. If you keep getting password
prompts that never accept your password, this means that your web
server is not properly configured to pass authentication info on to
Zope. See the doc/WEBVSERVER.txt file for information on correctly
configuring your web server to pass authentication information.
3. I have installed Zope, and when I go to the URL in my web
browser, I get a "Connection refused" error.
Probably this means that Zope has failed to start. You should try
to start Zope in the foreground and look for error messages.
You can do this by giving the command "./bin/zopectl fg" in your
Zope instance. If there are errors, the last error shown should
explain what went wrong.
4. When I go to a URL for an application that isn't running, it
takes quite a while to startup. Why is that?
The application has to get into memory and then get
the database loaded. Depending on database file size, this might
take a while. Packing your Zope database at regular intervals
can reduce startup time.
5. I have forgotten the only password used to access the site or
I have modified the security settings in such a way that even
I can't get access. How do I fix it?
Assuming you have write access to the directory where Zope is
installed, you can create a temporary "emergency user" using
the 'zpasswd.py' script::
python bin/zpasswd.py access
Follow the prompts to enter a user name and password.
'zpasswd.py' will write the file named 'access'. Zope will
look for this file the next time it starts. After restarting,
browse to Zope's management interface and use the name and
password you entered.
As the emergency user, you are allowed to create user folders
and user accounts as well as adjust security settings but you
are not allowed to create objects like folders. This is a
safety precaution.
See more details in the file SECURITY.TXT.
Managing the Zope process
1. How do I find the application server in my process listing?
When running Zope, there will be a .pid file in var/Z2.pid
which contains two process IDs.
2. If I have more than one Zope process running on the same
machine, how do I tell them apart in "ps" listings?
When running under ZServer, the Zope processes will show up in
the listings with 'run.py'. (You may need to do a long listing
to see it.) Look for the pids listed in var/Z2.pid.
3. Is it OK to use 'kill' to shut down the process?
If you started zope with the command "zopectl start", the command
"zopectl stop" will shut down Zope.
You can also shut down the process using the Shutdown button in
the Control Panel. Alternatively, the URL:
'Control_Panel/manage_shutdown'
will, with a suitable username and password, shutdown the
application. If you need a non-interactive way to shutdown your
application, e.g. from a script, then write a program that sends
a web request to that URL with the appropriate username and
password.
If you must, you can shut down the application by killing it.
The respective var/Z2.pid file will have the pids.
Upgrading from Earlier Versions of Zope
1. How can I upgrade to the latest Zope 2 version?
The usual procedure when installing a new version of Zope is:
- Create a new environment (see doc/INSTALL.txt).
- Include your application code in the environment.
- Copy your database files, (often var/Data.fs) from your old
environment into your new environment's var/ directory.
Only do this while the old database files are not in use.
- Update etc/zope.conf with any changes you made in your
old environment.
- Start the new application process. (Be sure the old process
is not running.)
2. CMF doesn't work!
Check that you have a recent stable version of CMF.
CMF is available at http://www.zope.org/Products/CMF/
3. Plone doesn't work!
All Plone versions require a certain Zope version.
Check the Plone release informations on http://www.plone.org
General
1. My browser is giving a message, 'Sorry, an error occurred.'
How do I find out what the real error is?
Step number one in these scenarios is to check the error log
on your server. The standard error page should provide you with a
link directly to the log entry for that error.
If something has gone wrong with the standard error page itself,
or if you are using a modified error page, this link may be
missing. If this happens, you can visit /event_log/manage_main and
browse the recent errors.
In general, error_log will show the *traceback* for errors.
This traceback explains the error message.
Occasionally you won't see any error message. Rather, the HTML
source will contain the last good HTML returned by the request
before the error occurred. This is due to caching by the
browser. Clear your cache and view the HTML source again.
2. I'm using Python 2.x and I'm having a problem ...
The correct version of Python should always be automatically detected
and used when you configure and install Zope. In general, you
should let the configure script do its job and don't try to
force an unsupported version of Python!

Zope History
This file contains change information for previous versions of
Zope. Change information for the current release can be found
in the file CHANGES.txt.
Zope 2.11.3 (unreleased)
Bugs Fixed
- configure script: setting ZOPE_VERS to '2.11'
- Products.PluginIndexes.PathIndex: backported doc fixes /
optiimizations from trunk (and ExtendedPathIndex).
- Updated 'pytz' from '2007f' to '2008i'.
- Moved svn:externals for 'mechanize', 'ClientPath', and 'pytz' to
versions managed outside the Zope3 trunk.
- Testing.ZopeTestCase: Remove quota argument from DemoStorage calls in
preparation for ZODB 3.9.
Zope 2.11.2 (2008/10/24)
Bugs Fixed
- updated to ZODB 3.8.1
- DateTime conversion of datetime objects with non-pytz tzinfo.
Timezones() returns a copy of the timezone list (allows tests to run).
(Backport of r89373 from trunk).
- LP #253362: better dealing with malformed HTTP_ACCEPT_CHARSET headers
- Testing.ZopeTestCase: installPackage was tied to the ZopeLite layer.
Zope 2.11.1 (2008/07/17)
Bugs Fixed
- Suppressed DeprecationWarning during import of ZPublisher.Iterators:
that module needs to use Z2-style interfaces in 2.11, for BBB, but
the Interface module itself issues the warning on import.
- Launchpad #246748: added 'immediate' option to sendXXX() methods
for sending a mail immediately by-passing the zope.sendmail delivery
mechanism
- Launchpad #246290: fixed backward compatibility issue
- zope.testing : updated to 3.5.3
- zope.viewlets: updated to 3.4.2
- zope.sendmail: updated to 3.5.0 (fixing Launchpad #230831)
Zope 2.11.0 (2008/06/15)
Restructuring
- Noted long-standing but silent deprecation of Zope2-style
interfaces (on import of the Interface package). That package
is already gone on the trunk.
Bugs Fixed
- Launchpad #229549: Don't ignore 'debug' flag when rendering
page templates (thanks to Eric Steele for the patch).
- Fixed against-the-rules zope.conf option 'fast_listen' to read
'fast-listen' (dash, not underscore).
Zope 2.11 rc 1 (2008/05/08)
Bugs Fixed
- Launchpad #142350: Display description for properties as row title,
if present.
- Launchpad #200007: DateTime(anotherDateTime) now preserves the
timezone.
- Launchpad #213311: Handle "unsubscriptable object" errors
during publishing traversal.
- Products.Five: Fixed vocabulary lookup broken in 2.11 beta 1.
ZopeVocabularyRegistry wasn't hooked up on startup.
- Launchpad #143813: zopectl now exits non-zero when
child processes fail.
- Products.Five: Resynced browser.adding with zope.app.container.
This fixes some minor bugs and removes deprecated code.
- Launchpad #173658: Removed dead code in OFS.Traversable's
'unrestrictedTraverse' (apparent NameError).
- Launchpad #198274: "empty" ZopePageTemplates could not be
unpickled.
Zope 2.11 beta 1 (2007/12/29)
Restructuring
- Moved two implements declarations from Five into the proper classes.
- Document.sequence: replaced by zope.sequencesort
- All Products folders as well as the zope and zope.app folders are
declared as setuptools namespace packages now. See
http://peak.telecommunity.com/DevCenter/setuptools#namespace-packages
for more information about namespace packages.
- ZPT: removed display of ZPT warnings since warnings were
removed from the zope.pagetemplate implementation
- Ship Zope with a standard docutils 0.4 distribution, instead
of a patched one. Both trusted and untrusted code are still
protected against unwanted file inclusion.
- Removed ZGadflyDA (deprecated since Zope 2.9). The code is
still available from svn.zope.org/Products.ZGadflyDA.
- Removed OFS.content_types (deprecated since Zope 2.9)
- Undeprecated 'zLOG', which will remain a backward-compatibility
shim for the Python logging module.
- Indexes: Removed unused parameters from '_apply_index' methods.
- Removed deprecated support for product initialization based on
'__ac_permissions__' and 'meta_types' attributes.
- reStructuredText/ZReST: setting raw_enabled to 0 for security
reasons
- OFS Image: Image and File updated to use isinstance(data, str)
and raises TypeError upon encountering unicode objects.
- OFS Application: Updated deprecation warnings.
Support for '__ac_permissions__' and 'meta_types' will be removed in
Zope 2.11, 'methods' support might remain longer.
Features added
- Zope2 startup: Zope will now sends DatabaseOpened and
ProcessStarting events during startup
- Testing.ZopeTestCase: Introduced a "ZopeLite" test layer, making it
possible to mix ZTC and non-ZTC tests much more freely.
- Testing/custom_zodb.py: added support use a different storage other
than DemoStorage. A dedicated FileStorage can be mount by setting the
$TEST_FILESTORAGE environment variable to a custom Data.fs file. A
ZEO server can be configured using the $TEST_ZEO_HOST and
$TEST_ZEO_PORT environment variables. This new functionality allows us
to use the standard Zope testrunner for writing and running tests
against existing Zope installations.
- The ZPublisher HTTP request has now both the debug and locale
attributes available, like its Zope 3 counterpart. The debug attribute
was so far limited to code from the zope.* namespace in order to make
the Zope 3 ZPT engine work. The locale attribute provides access to an
zope.i18n.interfaces.locales.ILocale object with access to locale
related information like date / time formatting or translated language
and country names. Form variables of both debug and locale will shadow
these two attributes and their use is therefor discouraged.
- MailHost: now uses zope.sendmail for delivering the mail. With this
change MailHost integrates with the Zope transaction system (avoids
sending dupe emails in case of conflict errors). In addition MailHost
now provides support for asynchronous mail delivery. The 'Use queue'
configuration option will create a mail queue on the filesystem (under
'Queue directory') and start a queue thread that checks the queue
every three seconds. This decouples the sending of mail from its
delivery. In addition MailHosts now supports encrypted connections
through TLS/SSL.
- integrated ZODB 3.8 (featuring BLOB support)
- integrated latest Zope3 components (aka Zope 3.4)
- Support for using zopectl on Windows has been added. All commands are
supported and there are two Windows specific ones: install and remove,
which install or remove the Windows service. The start, stop and
restart commands handle the Windows service. In order to use them, you
need to call 'bin\zopectl install' once.
- ZCatalog result objects (catalog brains) now have an interface,
ZCatalog.interfaces.ICatalogBrain.
- PythonScripts: allow usage of Python's 'sets' module
- added 'fast_listen' directive to http-server and webdav-source-server
sections in etc/zope.conf in order to defer the opening of the sockets
until the late startup phase. This in in particular useful when running
Zope behind a loadbalancer (patch by Patrick Gerken).
- AccessControl.Role: added new method
manage_getUserRolesAndPermissions().
- AccessControl: the form behind the "Security" tab has a new form
for user-related reporting of permissions and roles
- Zope 3-based exception views can now be registered in ZCML for
various exceptions that can be raised by Zope. Registering an
exception view can be done like this::
<browser:page
for="zope.publisher.interfaces.INotFound"
class=".view.SomeView"
name="index.html"
permission="zope.Public" />
Relevant exceptions that can have views are:
o zope.interface.common.interfaces.IException
o zope.publisher.interfaces.INotFound
o zope.security.interfaces.IForbidden
o zope.security.interfaces.IUnauthorized
Note that the name has to be 'index.html' for the exception
view to work. (patch by Sidnei da Silva from Enfold,
integration by Martijn Faassen (Startifact) for Infrae)
- DateTime now uses pytz for time zone data. This means support
for more time zones and up to date daylight saving time
information.
Bugs Fixed
- Collector #2113: 'zopectl test' masked Ctrl-C.
- Collector #2190: Calls to zope.security.management.checkPermission
weren't rerouted to Zope 2's security policy.
NOTE: If you already have a Zope 2.10 instance running, you
will either have to recreate it or add the following lines to
the end of the etc/site.zcml file::
<securityPolicy
component="Products.Five.security.FiveSecurityPolicy" />
- Collector #2223: Evaluation of booleans in TALES and the
'default' variable.
- Collector #2213: Can't edit "old" ZopePageTemplate instances.
- Collector #2235: A number of ZCatalog methods were doing boolean
evaluation of objects that implemented __len__ instead of checking
them against None. Replaced a number of "if not obj" with
"if obj is None".
Zope 2.10.8 (unreleased)
Restructuring
- Added 'InitializeClass' alias in 'App.class_init' to ease migration.
In Zope 2.12 it will be recommended to import 'InitializeClass' from
'App.class_init' instead of 'Globals'.
- Moved 'ApplicationDefaultPermissions' from 'App.class_init' to
'AccessControl.Permissions', in order to break an import cycle
in third-party code which avoids imports from 'Globals.' Left
the class importable from its old location without deprecation.
Bugs fixed
- LP/#143873: Fixed problems when no HTTP_ACCEPT_CHARSET is in the
request. This required an update of zope.publisher to 3.3.3.
- LP/#324876: tighened regex for detecting the charset
from a meta-equiv header
- Acquisition wrappers now correctly proxy __iter__.
- Launchpad #174705: ensure that the error info object exposed to a
'tal:on_error' handler has attributes visible to restricted code.
Zope 2.10.7 (2008/10/24)
Bugs fixed
- Ensure that response header values cannot embed CRLF pairs, which
violate the HTTP spec (RFC 2616).
- Launchpad #282677: fixed implementation of guarded_map and
provided tests and implementation for guarded_zip
(RestrictedPython).
- Lauchpad #143736,#271395: fixed AttributeError' on _ltid in TempStorage
- 'AccessControl.ZopeGuards.guarded_import' mapped some Unauthorized
exceptions onto ImportErrors: don't do that! Also, removed
mutable defaults from argument list, improved tests.
- LP #281156: 'AccessControl.SecurityInfo.secureModule' dropped
ModuleSecurity for failed imports, obscuring later attempts to
import the same broken module.
- LP #142667: Updated to ZODB-3.7.3 to fix problem with product
auto-refresh.
- Updated to Five 1.5.8
- Launchpad #245649: the Products package is now a proper
"namespace package" under the rules specified by setuptools.
- Fixed outdated transaction.commit(1) call in
ZODBMountPoint.SimpleTrailblazer
- Launchpad #239636: Ensure that HEAD requests lock an empty body
for NotFound errors.
- Launchpad #229549: Don't ignore 'debug' flag when rendering
page templates (thanks to Eric Steele for the patch).
- integrated Hotfix-2008-08-12
- Launchpad #267545: DateTime(DateTime()) now preserves the
correct hour
- Launchpad #262313: respect the 'Expand macros when editing' flag
when editing a page template through the ZMI
Zope 2.10.6 (2008/05/10)
Bugs fixed
- Launchpad #142350: Display description for properties as row title,
if present.
- Launchpad #200007: DateTime(anotherDateTime) now preserves the
timezone.
- Launchpad #213311: Handle "unsubscriptable object" errors
during publishing traversal.
- Launchpad #143813: zopectl now exits non-zero when
child processes fail.
- Launchpad #173658: Removed dead code in OFS.Traversable's
'unrestrictedTraverse' (apparent NameError).
- Launchpad #198274: "empty" ZopePageTemplates could not be
unpickled.
- zope.security: switched to use standalone 3.3.3 version, which
contains a backport of a huge performance bugfix from the 3.4 branch.
- Launchpad #164783: Indexes were migrated on initial creation of a
ZODB.
Zope 2.10.5 (2007/10/30)
Other changes
- Turned deprecation warnings for manage_afterAdd, manage_beforeDelete
and manage_afterClone methods into discouraged warnings. These methods
will not be removed in Zope 2.11, but stay for the foreseeable future.
Using events is still highly encouraged.
Bugs fixed
- Launchpad #147201: treat container-class in zope.conf as a string,
making it possible to use types from extra products directories.
- Collector #2358: backported fix making 'Products' package a real
"namespace package" from the trunk.
- Collector #2287: form ':record' objects did not implement enough of
the mapping interface.
- Collector #2352: fix in OFS.Traversable
- Collector #2346: username logging in FCGI crashed the server
- ZopePageTemplate's pt_edit did not recognize content type arguments
which had a charset information included.
- Collector #2332: SessionDataManger: don't swallow ConflictErrors
- Collector #2339: ZPT: fixed unicode issue when using the 'structure'
directive
- Launchpad #151020: HTTP_CHAR_SET headers containing 'x-user-defined'
caused a LookupError exception. Unknown encodings are from now on
silently discarded.
Zope 2.10.4 (2007/06/23)
Other changes
- updated to ZODB 3.7.1
- updated to Zope 3.3.2
- updated to Five 1.5.5
Bugs fixed
- Collector #1306: Missing acquisition context on local roles screen.
- Collector #2153: Supporting unquoted cookies with spaces.
- The REQUEST no longer accepts holds after it has been closed.
- Collector #1441: WebDAV compatibility with Windows Web Folders
restored by adding a configuration variable that controls the
sending of the non-standard MS-Author-Via and Public
headers. Thanks for PatrickD for the the hard work coming up
with an initial patch.
(http://zope.org/Collectors/Zope/1441)
- Fixed bug in ZPublisher.BaseRequest with persistent site managers. An
EndRequestEvent was thrown after the ZODB connection was already
closed and thus the site manager not being available anymore.
- Collector #2295: Comments in PythonScripts could lead to syntax
errors
- Collector #2307: ObjectCopiedEvent not dispatched to sublocations.
- Collector #2304: fixed markup issue in ptEdit.zpt
- Collector #2260: fixed Examples.zexp
- Collector #2320: HTTPResponse setHeader lowercased keys but getHeader
did not, causing lookups of 'Content-Type' to fail
- Collector #2321: Skip trusted proxies when extracting the client IP
address from the request.
- Collector #2318: Allow override of zopectl's control socket in
zope.conf
- Collector #2316: correctly unpack DateTimeIndex dates when browsing the
index.
- Collector #1866: a 304 HTTP status should not have a content length.
- Collector #2300: delimit *all* HTTP Response headers with CRLF.
Zope 2.10.3 (2007/03/25)
Bugs fixed
- Collector #2298: webdav.Resource.COPY and webdav.Resource.MOVE did
not send the expected copy/move events.
- Collector #2296: Fixed import of ZClass products, broken by removal
of BBB support for pasting objects whose meta_type info was
permission-free.
- Collector #2294: Protected DOS-able ControlPanel methods with the
same 'requestmethod' wrapper.
- Collector #2294: Protected various security mutators with a new
'postonly' decorator. The decorator limits method publishing to
POST requests only, and is a backport from Zope 2.11's requestmethod
decorator factory.
- Collector #2289: restored compatibility with PTProfiler
- No longer opens a zodb connection every time a ProductDispatcher
is looked up.
- Collector #2288: @ and + should not be quoted when forming
request URLs in BaseRequest and HTTPRequest
- Undeprecated 'zLOG', which will remain a backward-compatibility
shim for the Python logging module.
- PageTemplate/ZRPythonExpr.py: expressions represented as unicode string
caused UnicodeDecodeErrors.
Zope 2.10.2 (2007/01/26)
Bugs fixed
- Updated Zope 3 to bugfix release 3.3.1.
- Collector #2261: Acquisition when creating objects via Webdav.
- Collector #2269: fixed broken FTP support for ZPT
Zope 2.10.2 beta 1 (2007/01/14)
Bugs fixed
- Fixed Collector #2190: Calls to
zope.security.management.checkPermission aren't rerouted to
Zope 2's security policy.
NOTE: If you already have a Zope 2.10 instance running, you
will either have to recreate it or add the following lines to
the end of the etc/site.zcml file::
<securityPolicy
component="Products.Five.security.FiveSecurityPolicy" />
- Fixed Collector #2223: Evaluation of booleans in TALES and the
'default' variable.
- Reverted backward-incompatible fix for Collector #2191.
- Fixed the creation of lib/python/Zope2/version.txt
- added Python 2.4.4 as optimal Python version to 'configure'
- the ZopePageTemplate implementation now uses unicode
internally. Non-unicode instances are migrated on-the-fly to
unicode. However this will work only properly for ZPT
instances formerly encoded as utf-8 or ISO-8859-15. For other
encodings you might set the environment variable
ZPT_REFERRED_ENCODING to insert your preferred encoding in
front of utf-8 and ISO-8859-15 within the encoding sniffer
code. In addition there is a new 'output_encodings' property
that controls the conversion from/to unicode for WebDAV/FTP
operations.
- the ZPT implementation has now a configurable option in order
how to deal with UnicodeDecodeErrors. A custom
UnicodeEncodingConflictResolver can be configured through ZCML
(see Products/PageTemplates/(configure.zcml,
unicodeconflictresolver.py, interfaces.py)
Zope 2.10.1 (2006-11-22)
Bugs fixed
- Collector #2191: extended DateTime parser for better support
to the ISO8601 specification.
- Reworking of _cached_result in Shared.DC.ZRDB.DA.DA:
- fixed KeyError reported in Collector #2212
- fixed two memory leaks that occurred under high load
- fixed broken cache keys for people using the obscure
Shared.DC.ZRDB.DA.DA.connection_hook
- fixed incorrect cache ordering resulting in newer results
being dumped when the cache became too large.
- Collector #2232: Can't call DTML templates from Page Templates
- Collector #2213: Can't edit "old" ZopePageTemplate instances.
- Collector #2237: 'make' doesn't tell you to run 'make inplace'
before running 'make instance'.
- Collector #2235: A number of ZCatalog methods were doing boolean
evaluation of objects that implemented __len__ instead of checking
them against None. Replaced a number of "if not obj" with
"if obj is None".
- Collector #2208: rewriting/setting the 'charset' part of the
content-type HTTP header will be done only for `text/*`
- Collector #2209: ZTUtils module could not be used inside ZPT
- Collector #2206: Set PYTHONPATH to include existing PYTHONPATH
in skel/bin/zopectl.in and skel/bin/runzope.in
Zope 2.10.0 (2006/10/04)

Bugs fixed
- Collector #2117: Don't choke in 'unrestrictedTraverse' for '+'
path elements.

- Collector #2152: Fixed MailHost documentation; simple_send does not
process or validate its arguments in any way.
- Collector #2175: ZTUtils.make_hidden_input did not escape
double-quotes.
- Collector #2176: Fixed bad logging call.
- Collector #1907: Moved 'alt' property from File to Image.
- Collector #1983: Specifying session-resolution-seconds >= 1200 caused
Zope startup to fail.
- Collector #2169: webdav.Resource.COPY did not send ObjectClonedEvent.
- Collector #2178: Fix ZopeTestCase doctest support for layers
Zope 2.10.0 beta 2 (2006/08/20)
Bugs Fixed
- Collector #2155: Fix wrong parameter being passed to
logger's error() method, with tests.
- Updated Five to stable 1.5 release.
- Traversal order changes were causing WebDAV requests which used
acquisition to fail.
- Collector #2157: Expose name of broken class in SystemError raised
from '__getstate__' of a broken instance.

variable
- reStructuredText/ZReST: setting raw_enabled to 0 for security
reasons
- Collector #2113: 'zopectl test' masked Ctrl-C.
- OFS Image: Image and File updated to use isinstance(data, str)
and raises TypeError upon encountering unicode objects.
- OFS Application: Updated deprecation warnings.
Support for '__ac_permissions__' and 'meta_types' will be removed in
Zope 2.11, 'methods' support might remain longer.
- Collector #2136: Map ResourceLockedError to the correct response code.
- Collector #2016: DemoStorage couldn't wrap base storages without
an '_oid' attribute.
- Collector #2118: Empty TALES path expressions are allowed
in Zope 2.

1. Unacquired attributes
2. Views
3. Acquired attributes
According to consensus in z3-five mailing list:
http://codespeak.net/pipermail/z3-five/2006q2/001474.html
- The defaultView directive now only looks up views, not attributes.
- Collector #2178: Fix ZopeTestCase doctest support for layers
Other Changes
- Disabled docutils file inclusion completely, rather than trying
to jigger it via configuration settings.
- Returned to the "classic" './configure && make && make install'
recipe, dropping the use of 'zpkg' for building Zope2 releases.
Zope 2.10.0 beta 1 (2006/05/30)
Restructuring
- Zope 2.10+ now includes site.zcml as part of its instance
creation skel directory. As a consequence Five now requires
this file to exist in every instance. If upgrading a site
from Zope 2.9 to 2.10, you will need to copy site.zcml and
package-includes/ from your installed Zope installation
location (skel/etc/) into the etc/ directory of your upgraded
instance.
The rationale for requiring this new file is to bring Zope 2
instances closer in consistency to Zope 3 instances. It also
eases use of Zope 3 coding techniques in Zope 2 and removes
some confusion when trying to run pure Zope 3 applications on
Zope 2.
- Products.PageTemplates now uses the Zope 3 ZPT implementation
in zope.pagetemplate.
- The TAL package has been deprecated in favour of the TAL
engine from zope.tal.
- Products.PageTemplates.TALES has been deprecated in favour of
the TALES engine from zope.tales.
- ZTUtils.Iterator has been deprecated in favour of the TALES
iterator implementation in zope.tales.tales.
- ZCatalog: removed manage_deleteIndex(), manage_delColumns()
which were deprecated since Zope 2.4
- deprecated the zLOG module. Use Pythons 'logging' module instead.
- replaced all zLOG occurences (expect the zLOG module itself) with
the 'logging' module
- PluginIndexes/TextIndex is deprecated. Use ZCTextIndex instead
- the 'StructuredText' module is deprecated. Use zope.structuredtext
instead
- removed ZopeTutorial (Elvis is now really dead)
- ZClasses are deprecated and should no longer be used. In addition
any code related to the ZClasses (re)distribution mechanism is
removed.
- ZGadyFlyDA/Gadfly is deprecated
- deprecated OFS.content_types (to be removed in Zope 2.11) and
replaced all occurences with zope.app.content_types
- OFS.content_types: moved code to zope.app.content_types and added
method aliases
- Using FastCGI is offically deprecated.
Features added
- added PluggableIndexes/interfaces/IIndexConfiguration (on request
by the GenericSetup community)
- Included Zope 3.3 and corresponding Five 1.5 release.
- There is now a default favicon.ico.
- Experimental WSGI and Twisted support for http.
Zope now has a WSGI interface for integration with other
web-servers than ZServer. Most notably Twisted is supported.
The WSGI application is ZPublisher.WSGIPublisher.publish_module
You can make ZServer use the twisted interface with the
"use-wsgi on" keyword in the http-server section in zope.conf.
You can run Twisted by installing Twisted (2.1 recommended) and
replacing the http-server section with a server section in
zope.conf. It is not possible to run a Twisted server together with
a ZServer at the same time::
<server>
address 8080
type Zope2-HTTP
</server>
WSGI: http://www.python.org/dev/peps/pep-0333/
Twisted: http://twistedmatrix.com/
- The traversal has been refactored to take heed of Zope3s
IPublishTraverse adapter interfaces. The ZCML directives
five:traversable and five:defaultViewable are therefore no
longer needed, as everything now is five:traversable and
five:defaultViewable.
There was a bug in earlier versions of Five that allowed you
to do custom publishing traversal with ITraversable adapters.
This bug has been corrected. Anybody using ITraversable
adapters need to convert them to IPublishTraversal adapters.
- Testing.makerequest: Added an 'environ' argument so
clients can use mappings other than os.environ.
- Updated to Docutils 0.4.0
- reStructuredText: The default value for the 'stylesheet'
property has been changed from 'default.css' to None because
there is no 'default.css' file by default.
- ZReST: rewritten render() method to integrate it smoothly
with Docutils 0.4.0. The default value for the 'stylesheet'
property has been changed from 'default.css' to None because
there is no 'default.css' file by default.
- Added a "clock server" servertype which allows users to
configure methods that should be called periodically as if
they were being called by a remote user agent on one of Zope's
HTTP ports. This is meant to replace wget+cron for some class
of periodic callables.
To use, create a "clock-server" directive section anywhere
in your zope.conf file, like so::
<clock-server>
method /do_stuff
period 60
user admin
password 123
host localhost
</clock-server>
Any number of clock-server sections may be defined within a
single zope.conf. Note that you must specify a
username/password combination with the appropriate level of
access to call the method you've defined. You can omit the
username and password if the method is anonymously callable.
Obviously the password is stored in the clear in the config
file, so you need to protect the config file with filesystem
security if the Zope account is privileged and those who have
filesystem access should not see the password.
Descriptions of the values within the clock-server section
follow::
method -- the traversal path (from the Zope root) to an
executable Zope method (Python Script, external method,
product method, etc). The method must take no arguments or
must obtain its arguments from a query string.
period -- the number of seconds between each clock "tick" (and
thus each call to the above "method"). The lowest number
providable here is typically 30 (this is the asyncore mainloop
"timeout" value).
user -- a zope username.
password -- the password for the zope username provided above.
host -- the hostname passed in via the "Host:" header in the
faux request. Could be useful if you have virtual host rules
set up inside Zope itself.
To make sure the clock is working, examine your Z2.log file. It
should show requests incoming via a "Zope Clock Server"
useragent.
- Added a 'conflict-error-log-level' directive to zope.conf, to set
the level at which conflict errors (which are normally retried
automatically) are logged. The default is 'info'.
- 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.
- 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.
- Use new-style security declarations everywhere possible. This
means remove the use of __ac_permissions__, foo__roles__ and
default__class_init__. A few corner cases can't be converted
because of circular imports.
- Fixed unclear security declarations. Warn when an attempt is
made to have a security declaration on a nonexistent method.
- updated to ZPL 2.1
- interfaces: Added 'Interfaces' tab to basic core objects.
This is a Five feature and only available if the classes are made
five:traversable. It allows to inspect interfaces and to assign
marker interfaces through the ZMI.
- webdav: Added support for the z3 WriteLock interface.
It is no longer necessary to have the WriteLockInterface in the
__implements__ list of lockable objects. All classes inheriting from
LockableItem inherit also the IWriteLock interface. Note that this
enables webdav locking for all subclasses by default even if they
don't specify the WriteLockInterface explicitly.
- App ProductContext: Made registerClass aware of z3 interfaces.
Z2 and z3 interfaces are registered side by side in the same tuple in
Products.meta_types. IFAwareObjectManagers like the ZCatalog work now
with z3 interfaces as well.
- Zope now sends Zope 3 events when objects are added or removed
from standard containers. manage_afterAdd, manage_beforeDelete
and manage_afterClone are now deprecated. See
lib/python/Products/Five/tests/event.txt for details.
- Zope now utilizes ZODB 3.6. It had previously used
ZODB 3.4. As a result, the DBTab package was removed, as
ZODB 3.6 has multidatabase support that makes DBTab
unnecessary.
- Added a 'product-config' section type to zope.conf, allowing
arbitrary key-value mappings. Products can look for such
confgiurations to set product-specific options. Products mwy
also register their own section types, extending the
'zope.product.base' type. (see the example '<product-config>'
section in skel/etc/zope.conf.in for sample usage).
- 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.
- AccessControl, Acquisition, App, OFS, webdav, PluginIndexes,
ZCatalog and ZCTextIndex: Added some Zope 3 style interfaces.
This makes the bridged interfaces shipped with Five obsolete.
- ZConfig extension, address now also accepts symbolic port names
from etc/services (unix) or etc\services (win32)
- ZPublisher.HTTPRequest.FileUpload now supports full file
object interface. This means Iterator support was added. (for
line in fileobject: ..., as well as fileobject.next() and
fileobject.xreadlines() ) Collector #1837
- Switched the bundled Zope 3 to release 3.2 and upgraded the
Five product to version 1.3 (see Products/Five/CHANGES.txt).
- The PageTemplate implementation now uses Zope 3 message
catalogs by default for translation. Old-style translation
services such as Localizer or PlacelessTranslationService are
still supported as fall-backs. See Products/Five/doc/i18n.txt
for more information.
- Switched to the new improved test runner from Zope 3. Run
test.py with -h to find out more.
- lib/python/docutils is now a reference to docutils package
from the Zope 3 source tree (to get rid of redundant packages)
Bugs Fixed
- Collector #1447: When editing content on a virtual-hosted zope,
AcceleratedHTTPCacheManager now purges the correct URL.
- When you add roles in manage_access, roles are now stripped of
any leading or trailing spaces.
- Collector #2062: Fix manage_historyCopy, which was broken, and write
tests for it.
- Collector #2061: Fix problems where windows line endings are passed
to restricted code compilers.
- Collector #2051: Applied patch by Yoshinori Okuji to fix some
XML export/import problems, including tests for that feature.
- Collector #2037: fixed broken ACTUAL_URL for '/'
- Missing import of NotFound in webdav.Resource
- Collector #1819: fixed method signature of
MountedObject.SimpleTrailblazer._construct()
- Collector #2019: removed validateValue() from cAccessControl (already
removed in former Zope versions from the AccessControl Python
implementation)
- Collector #1991: ZPublisher did not deal properly with a trailing
%20 in the URL
- zope.app.introspector was not included with the source archive
- Collector #2013: improved XHTML conformance of error messages,
some of which did not close '<p>' tags.
- Collector #2002: fixed broken 'ls -R' functionality (didn't
recurse properly subclasses of OFS.Folder)
- Collector #1992: unified the visible hostnames of the FTP and
HTTP servers
- Collector #1999: fixed broken FTP rename functionality
(RNFR now returns 350 as status code instead 250)
- HTTPResponse: for XML content the encoding specified within
the XML preamble is adjusted to the real encoding of the content
as specified through the 'charset' within the content-type
property.
- 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.
- For content-type HTTP headers starting with 'text/' or 'application/'
the 'charset' field is automatically if not specified by the
application. The 'charset' is determined by the content-type header
specified by the application (if available) or from the
zpublisher_default_encoding value as configured in etc/zope.conf
- Collector #1976: FTP STOR command would load the file being
uploaded in memory. Changed to use a TemporaryFile.
- OFS ObjectManager: Fixed list_imports() to tolerate missing
import directories.
- Collector #1621, 1894: Removed support for use of long-deprecated
'whrandom' module.
- OFS PropertySheets / webdav: Fixed dav__resourcetype.
__dav_collection__ with a false value was overridden by
isAnObjectManager.
- added missing Zope 3 imports: zope.app.intid, zope.app.keyreference,
zope.app.session, zope.contentprovider, zope.viewlet
Other
- AccessControl.User: Use a better __repr__.
- 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.
- The ImageFile module has finally been deprecated for good and
will be removed in Zope 2.11. Use App.ImageFile instead.
after Zope 2.8.1
- The '@' character is now allowed in object ids (RFC 1738 allows it).
Bugs Fixed
- 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.
- Collector #1895: testrunner: omitting the 'var' from recursive
directory walking
- 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().
- 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
- 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)
Features added
- 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.
Bugs Fixed
- 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)
Features Added
- 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.
Bugs Fixed
- 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)
Bugs Fixed
- 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)
Features added
- Made WebDAV server distinguishable from the default HTTP
server both in the ZMI and in event.log.
- Included BTreeFolder2
Bugs fixed
- 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)
Features added
- 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.
Bugs fixed
- 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)
Features added
- 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.
Bugs fixed
- 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)
Features added
- 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:
o 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.
o Support for cyclic garbage collection.
o Ability to use new-style classes as base classes of Zope objects.
o 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.
Bugs fixed
- 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 #1436: applied patch to fix a memory leak in
cAccessControl.
- Collector #1431: fixed NetBSD support in initgroups.c
- Collector #1406: fixed segmentation fault by acquisition
- Collector #1392: ExternalMethod ignored management_page_charset
- unrestrictedTraverse() refactored to remove hasattr calls (which mask
conflict errors) and for greater readability and maintainability.
- Zope can now be embedded in C/C++ without exceptions being raised
in zdoptions.
- Collector #1213: Fixed wrong labels of cache parameters
- Collector #1265: Fixed handling of orphans in ZTUtil.Batch
- Collector #1293: missing 'address' parameters within one of the server
sections raise an exception.
- Collector #1345: AcceleratedHTTPCacheManager now sends the
Last-Modified header.
- Collector #1126: ZPublisher.Converters.field2lines now using
splitlines() instead of split('\n').
- 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
- ObjectManager no longer raises string exceptions
- Collector #1260: Testing/__init__.py no longer changes the
INSTANCE_HOME.
- 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.
- Collector #1139: tal:attributes didn't escape double quotes.
- 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.
- Collector #445: Add internal global declaration for Script bindings.
- Collector #616: Make CONTEXTS available to TALES Python expressions.
- Collector #1074: Give Script execution context a __name__
- Collector #1095: Allow TAL paths starting with '/varname' as a
preferred spelling for 'CONTEXTS/varname'.
- Collector #391: Cut and paste now requires delete permissions.
- Collector #331: Referenses to URL in manage_tabs was changed
to REQUEST.URL to prevent accidental overriding.
- 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 #951: DateTime(None) is now equal to DateTime()
- Collector #1056: aq_acquire() ignored the default argument
- Collector #1087: ZPT: "repeat/item/length" did not work as documented
in the Zope Book.
- Collector #721: Entities in tal:attribute values weren't
properly escaped.
- 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.
