Zope Changes
This file contains change information for the current Zope release.
Change information for previous versions of Zope can be found in the
file HISTORY.txt.
Zope 2.5.1
New Features
- Added the fsIndex feature. This adds a new BTree variant,
fsBTree, a module fsIndex.py that uses it, and some changes
to FileStorage.py to use fsIndex if it exists so that the
oid-to-offset index (pindex) is a BTree rather than a straight
dict.
- ZODB changes necessary to support StandaloneZODB were merged
Bugs Fixed
- Page templates will now not expand if expand=0 is passed to them.
- ZTUtils.Zope.Batch now has the same default orphan parameter
as ZTUtils.Batch.Batch. Calculation of previous batches with
non-zero orphans is fixed.
- Python-based Scripts that need to be recompiled for efficiency
now emit a single, much more explanatory log entry, per run.
The recompile() utility function works properly now.
- Caused sqltest implementation to match help system docs
Expression tags now work. "multiple" attribute now works.
type="nb" attr now works. (thanks to Christian Theune for
the patch)
- Fixed cAccessControl to incref __roles__ in imPermissionRole_of
- Fixed long standing bug in PythonScript where get_size returned
the incorrect length. This broke editing using EMACS via FTP or
WebDAV. Thanks to John Glavin at South River Technologies for
help finding the bug.
- Collector #207: fixed problem with inner links in STXNG
- Collector #210: HTML() function of StructuredText produced wrong
<h0> tags.
- Collector #227: improved handling of unicode string in TextIndex.py
with unmodified default encoding in site.py.
- Collector #166: ObjectManger.all_meta_types() implemented only
an incomplete filter based on interfaces.
- FTP: Downloading files through FTP has been broken since 2.4.0
because the downloaded file has been stored with a HTTP
header at the beginning of the file. Fixed!
- FTP: Spaces in usernames inside a FTP file listing are now
replaced by underscores to avoid confusion with some FTP clients.
- Added UnicodeSplitter to Windows build process
Zope 2.5.0 Final
Bugs Fixed
- Fixed a BTree problem where Py_None could be returned without
an INCREF (Thanks to Steve Alexander)
- The edit text area for File objects was not correctly HTML quoted.
- Added an asyncore fix for an issue that could cause ZServer to
hang on Linux 2.2 systems.
- Setting proxy roles on DTMLMethods and Documents has been broken
- Collector #99: items(), keys() and values() methods
of IIBucket objects has been broken when called with
min/max parameters.
- WebDAV: The long outstanding read-only problem with WinWord
and .html is finally solved. Zope sends now an additional ETag
header for DTMLMethods and DTMLDocuments. Many thanks to
Joachim Schmitz for this hint.
- PathIndex: fixed minor bugs, enhanced testsuite
- DTML-MIME tag: creates now a 'Mime-Version: 1.0' to make
some fussy email programs happy
- utilities/requestprofiler - fixed bugs in timed mode which could
show nonsensical results.
Features Added
- TextIndex/Splitters: the constructor of all three splitters
has now three new optional parameters:
'maxlen'=(1-256) - to specify the maximum length of
splitted words
'singlechar'=(1|0) - allows single characters to be indexed
'indexnumbers'=(1|0)- allows numbers to be indexed
The default values of all parameters reflect the standard
behaviour.
- Enhancements to utilites/requestprofiler.py:
Added readstats and writestats features which allow for saves and
reuse of profile stats between runs of the requestprofiler.
Added urlfocus mode. Urlfocus mode presents a summary of
activity within a period of time before and after the
invocation of a particular URL as it was recorded in the big M
log. This can be useful when trying to track down a problem
which you believe is related to some series of URL invocations
as opposed to a single URL invocation.
- added doc/ENVIRONMENT.txt to document all used environment
variables Zope is using
- Provided a much more robust tool for recovering data from
damaged FileStorage files:
Allow recovery of data when:
- either transaction or data records are damaged and when
- multiple parts of a file are damaged
The interface has changed to not modify in place.
Other features:
- Progress indicator
- Verbose output
- optional packing
- index creation
- The last entry in the breadcrumb path in the ZMI is now an
underlined hyperlink.
- Added a new script "utitilies/check_catalog.py" to perform
some consistency checks on a ZCatalog instance
- Added the following new products related to sessioning:
- browser id manager
- session data manager
- transient object container
- temporary folder
- Zope will create default sessioning objects on startup
- Zope will create an Examples folder on startup. This folder
contains a collection of simple example applications.
Bugs Fixed
- STXNG: added '+' as allowed character inside URLs
- enhanced the checks for 'Domains' field in the UserFolder
- Webdav: fixed broken MOVE and COPY commands
- Updated DTMLMethod validation support patch with version
by Steve Alexander
- <dtml-var "..." fmt="structured-text"> did not work
properly under some acquisition related reaons.
- pre-2.5 installation could not properly migrated to 2.5 because
of changes in the Splitter API
- ZODB conflict errors were logged at a severity that caused
tracebacks to be logged to the stupid log file "out of the box".
Because conflict errors happen under normal operations, and
their appearance in the log frequently alarms folks, typical conflict
error logging verbiage has been reduced, and traceback logging
has been changed to happen only at BLATHER log level, which
means that conflict tracebacks will only be logged if
STUPID_LOG_SEVERITY is set to -100 or lower.
Zope 2.5 Alpha 2
Bugs Fixed
- New accelerated security management bugfix in App/Manager.py,
changing calling sequence to positional parameters.
- STXNG: re-enabled inner now work also through DTML
and not only when using STXNG standalone
- STXNG: generated HTML is now more HTML4/XHTML compliant
(quoted attributes, inner links)
Zope 2.5 Alpha 1
Features Added
- re-enabled inner links for STXNG documents.
- Zope installations upgraded from pre-2.4 installations
did not show the WebDAV LockManager entry in the control panel.
- "requestprofiler.py" script in utilities now does better analysis,
including:
"active" in detailed output is now slightly more meaningful.
It is > 0 only if other requests started after it started
but before it finished. The greater the active count, the
more likely it is that something was going on at the time
in which the request ran that caused a slowdown.
Multiple files may be analyzed at the same time.
Also, script recognizes "U" opcode in big M logs as meaning a restart.
- Added a "preview" field to the edit form for Image
objects. This provides a preview of the actual image data on
the form to make it easier to know what you are working
on. The preview image is scaled if necessary to be useful
without being obtrusive.
- Added the ability to edit File object content in a
textarea. If the content of a File is a text type and the size
is less than 64K (the max size for text area data in some Web
browsers), then you can edit the content as you would a DTML
or other text-based object.
- New user management API for user folder objects was implemented.
As of Zope 2.5, manage_addUser, manage_editUser and manage_delUsers
form the official API for user management. The old grotesque way of
using manage_users is now deprecated.
The default implementation of these API methods simply call the
_doXXX versions of the methods that user folder authors have already
implemented, which means that these APIs will work for current user
folder implementations without any action on the part of the author.
User folder authors that implement the new manage_XXX API can get
rid of the old _doXXX versions of the methods, which are no longer
required (we only use them if the new api is not directly implemented).
API documentation for the User Folder API was also added to
the help system.
- Python compiler in RestrictedPython brought in sync with
main distribution. Made to be compatible with Python 2.2.
- Added links in the "debugging information" control panel
for viewing the contents of the ZODB cache.
- Added user password encryption capability, fulfilling the
needs described in the proposal at:
http://dev.zope.org/Wikis/DevSite/Proposals/EncryptedUserfolderPasswords
There is now a "properties" tab in user folders where you
can select whether passwords are stored encrypted.
- Locale support in STXNG has been broken (since 2.4.0)
- Added SOFTWARE_HOME, INSTANCE_HOME, and CLIENT_HOME to the
control panel to make it easer to tell what configuration of
Zope is running.
- Re-applied Medusa patch to allow proxy-like HTTP requests
(GET http://hostname:port/ HTTP/1.0)
- Objects indexed by the PathIndex can now provide a hook or an
attribute with the same name as the index name to provide
a customized path information other than using getPhysicalPath().
- Selecting "Clear Catalog" from the ZCatalog "Advanced" did not clear
the vocabulary associated with a TextIndex.
- Added updated and enhanced testsuite for STXNG.
- added getEntryForObject() for PathIndexes. Reworked PathIndex's
internal inverse index.
- API help topics can now document functions as well as classes.
- Security accelerations in c
- Accelerated C Document Template handling; Document Templates
can now do additional rendering in C, improving performance.
- Unicode support for ZCatalog:
- added new UnicodeSplitter
- ZCatalog now allows unicode strings as attributes
of objects to be indexed using a TextIndex
(see lib/python/ZCatalog/README.txt)
Bugs fixed
- WebDAV: Zope escaped nested object properties derived from
internal dav__* functions in PropertySheets.py although they
are considered to be safe and do not need any escaping. This
caused Zope to be completely incomplete with Windows XP. Fixed !
- WebDAV: '(' and ')' are now allowed in Ids for Zope objects.
This is needed when one tries to duplicate files using cut&paste
through Microsoft webfolders.
- Collector #2532: ZCatalog.availableSplitters is now protected
by security mechanism.
- Collector #2412: a read-only FileStorage has not been closed
properly.
- Collector #2390: Objects of type 'Help Image' were not properly
re-registered inside registerHelp().
- Fixed broken FTP download for larger files.
- Collector # 2396: StructuredText did not allow URLs containing "%"
- Collector # 2397: StructuredText could not handle underlined text
properly. Also <dtml-var stxdoc fmt="structured-text"> will no longer
produce <html>..<body> and </body>..</html>
- Collector #2438: Using a slice operation like [30:] on a
ZCatalog search result caused a MemoryError because
the __getslice__ implementation used range() instead
of xrange().
- Collector #2423: Searching a FieldIndexes for documents
with a blank string has been broken.
- WebDAV Lockmanager was not working due to a Python 2.1
incompatibility.
- Collector #2482: A COPY operation through WebDAV on a locked
resource left the destination resource in a locked state
so any WebDAV client was unable to unlock the destination
object. Locks are now cleared from the destination object.
- Error message AttributeError/_v_blocks when a DTMLfile is
not present or could not be read replaced by a more
informative message.
- Collector #2497: SERVER_PROTOCOL variable is now compliant
with the CGI specification and looks like "HTTP/1.1" instead
of "1.1"
- Creation of a TextIndex ignored the vocabulary setting.
- Fixed broken aquisition of vocabularies from a Catalog
by a TextIndex.
- Collector #2504: level parameter has not been passed to HTMLClass
constructor
- default for 'orphan' attribute of <dtml-in> is now 0 instead 3.
- Fixed conflict resolution problem in BTrees (BTreeTemplace/
_p_resolveConflict)
- Collector #2524: Medusa sent "HTTP/None..." as response header when
then HTTP version could not be determined from the HTTP request.
Now sending "HTTP/1.0..."
- queries for the PathIndex can now specified as tuple (path,level).
the level parameter inside a query overrides the optional
'level' parameter for a complete search request.
- Collector #2561: XXBucket.values() returned keys instead of values
- Fixed the API docs for user objects.
- Fixed bad interaction between ZCatalog and dtml-in (submitted by
Steve Alexander)
- Multiple links in a paragraph with mixed link notation
(quotation+colon+URL or quotation+comma+whitespace+URL) did not
work properly (thanks to Alastair Burt for reporting and submitting
the patch).
- Fixed case where DTMLMethod.py complained when it tried to remove
the accelerated DTML security validation routine after recursive
entry.
