Silva changes

  0.9.2.8

  0.9.2.7

    Bugs Fixed

        - Small fix in feedback message in tab status macro

        - Disabled sidebar invalidation while performing
          content upgrades.

  0.9.2.6

    Bugs fixed
 
        - Fulltext also indexes title, not just XML content.

        - Fixed some unicode errors in EmailMessageService

        - Cache is now bypassed if 'suppress_title' is in the request.

  0.9.2.5

    Features Added

        - Image elements in a Silva Document now have to possibility to
          link to the hires version or other URLs with a optional "_target".

    Bugs fixed

        - No Catalog indexes are created for Metadata fields which do
          not need indexing.

        - Metadata form and acquisition didn't work properly in all
          cases.

        - UI improvements in tab_edit and tab_publish

        - XML export of folders when the "export last version" option
          is checked, did not use correct Folder title.

        - Fixed two issues with the SQLDataSource and integer fields:
          the code doesn't try to convert the contents of the field to
          unicode anymore if it's not a plain string (fails with
          integers) and the code doesn't change the contents of the
          field to '' anymore when it's something else than None
          (previously it checked whether it resolved to true instead
          of checking for None).

  0.9.2.4

    Features Added

        - Import assets from a zipfile now creates Silva Folder for the
          zipfiles's directory structure.

    Bugs fixed

        - Fixed bug where the widget caches were not cleared correctly
          upon deletion of a Document.

        - Fixed rare or edge-case situations in the Publish tab. UI
          improvements, bugfixes and some code optimizations.

        - SilvaMetadata contained a bug which actually made metadata
          cataloging fail. This has been fixed in SilvaMetadata
          0.7.2, so the only upgrade necessary is in fact of this
          dependency. For convenience we've also done a new Silva
          release, but the only thing it contains is one new test for
          getting metadata.

  0.9.2.3

    Bugs fixed

        - Authors can now create new document versions again. This was
          a permission setting problem. It can be fixed by going to
          service_extensions and pressing 'refresh' for the Silva
          core.

        - Fixed two issues with the SQLDataSource and integer fields:
          the code doesn't try to convert the contents of the field to
          unicode anymore if it's not a plain string (fails with
          integers) and the code doesn't change the contents of the
          field to '' anymore when it's something else than None
          (previously it checked whether it resolved to true instead
          of checking for None).

        - Fixed a whole host of issues related to indexing. Indexing
          of objects was both done incorrectly and the performance was
          too slow. test_catalog was added which can be used to test
          indexing correctness, and fixes were made where problems
          were found. Indexing performance was increased by:

            * Avoiding indexing something too frequently in the Silva
              core.

            * Improving Formulator so that TALES expressions are
              cached. This avoids a massive Python expression
              compilation overhead. Upgrade Formulator to version
              1.5.0 for a massive boost in indexing performance.

            * Fixing Silva metadata to avoid quadratic behavior while
              indexing. Previously, for n elements that are indexed,
              for each element indexing the data for the n indexes was
              accessed, resulting in quadratic behavior while indexing
              (n * n values were accessed per object). Upgrade SilvaMetadata
              to version 0.7.1 for another boost in indexing performance.

            * Fulltext indexing of unapproved versions is avoided.

            * Old versions should now not show up in the catalog anymore.

        - Fix icon rendering. It should now be faster and more
          browser-cache friendly.
 
        - Fixed unicode issue when deleting a table column.

        - A number of things fixed in 0.9.1.x have also been fixed
          for 0.9.2.

  0.9.2.2

    Bugs Fixed

        - get CSS style iteration right for containers only containing 
          Assets (which otherwise would break the container view).

        - Add a silva root in the ploneCustom style sheet for the tabbar
          background images (which would not display if the silva root
          folder did not have 'silva' for id and be located directly in 
          the zope root).

        - Changed check_reserved_ids() function in the content upgrade
          script from breadth-first to depth-first. This works better for
          content hierarchies where folders with an invalid id containing
          content also with invalid ids, are being renamed.
                                                                                                    
        - The metadata tab wouldn't show the metadata set's title when it
          was available.

        - Be less aggressive about trying to add a Unicode Whitespace
          splitter, and accept if one is already there.

  0.9.2.1

    Features added

        - Added support for ExternalEditor, Silva Files and Images can now be
          edited using your favorite editor

    Bugs Fixed

        - Fix bug where viewing content normally restricted by an
          AccessRestriction, could be viewed via a Ghost.

        - Pressing upgrade more than once now doesn't mess up object titles
          anymore

        - All content types should now have the correct metadata sets setup
          for them (led to a KeyError on 'silva-extra' in all of the views
          of those content types)
  
  0.9.2 

    Features Added

        - Bulk import of files (for File Assets) and/or images (for Image
          Assets) using a zipfile.

        - New metadata architecture, which provides multiple configurable
          metadata sets. Sets can defined on a per object type basis and
          uses the catalog to make this metadata searchable.

        - Unicode support. All content and meta data can contain any character
          defined by the unicode standard. On upgrade you have replace or
          update your index_html set the the correct encoding; the default
          index_html does this.

        - Sidebar caching. For performance reasons, the sidebar is now cached,
          making it possible to use it throughout the site without slowing
          down page rendering.
          
        - High resolution image support. If you have PIL installed images can
          be both converted to JPEG or PNG and arbitrary scaled for web
          presentation. The high resolution image can be used for printing. 

        - Asset references and code element references will now be relative
          paths if the Assets are in the same container the Document is in,
          or in a subcontainer of this container. If not, the path will be
          an absolute path.

        - Docma queue viewer is now on both import and export screen. On import
          only Silva XML files are shown, on export only Word documents.

        - Export screen prefills email address and description.

        - Single Document import/export

        - Markup character escapes (entities)

        - Titles are now associated to document versions, not documents
          themselves. Different versions can have different titles.
 
        - Some XMLWidgets related cleanups to the editor.

    Bugs Fixed

        - (SQL)Datasources can now only be placed by ChiefEditors and up
          (using a Datasource in a document is not affected by this), and
          (SQL)Datasources now work with unicode.

        - The widgets cache would be cleared correctly upon Document
          deletion. This could result in inconsistent Document editor states
          if this Document has an id earlier held by a Document now deleted.

        - Setting a TOC level would display one level too much.

        - Fixed problems arising from allowing to create content objects
          which may shadow important internal objects (issue321) or 
          cause unfriendly Zope error messages (issue189)

        - A number of minor bugs, mainly in UI.

  0.9.1.10

    Bugs Fixed

      - There was a problem where files could be downloaded even from
        areas where viewing was restricted. This has been fixed.

  0.9.1.9

    Bugs Fixed

      - EditorSupportNested was passing along a document object as an
        object id. That can't be right. Fixed.

      - Unicode error for index markup in headings fixed.

  0.9.1.8

    Bugs Fixed

      - Better check for availablity of ExternalEditor.

      - The bug fixed in 0.9.1.7 regarding
        _allow_authentication_requests should have been fixed in a
        backward compatible way in 0.9.1.7, which it wasn't. Therefore
        old content and extensions broke. This release adds only some
        backward compatible code to resolve this issue. From now on,
        0.9.1.4 (and older 0.9.1.x) content and extensions should work
        again.
 
  0.9.1.7

    Features Added

      - Support for external editor is now complete, users don't have
        to manually setup anything anymore to use it.

    Bugs Fixed

      - Fixed bug in the upgrade script that lead to an
        AttributeError on '_allow_authentication_requests'

  0.9.1.6

    Bugs Fixed

        - Fix bug where viewing content normally restricted by an
          AccessRestriction, could be viewed via a Ghost.

  0.9.1.5

    Features Added
                                           
        - Added support for ExternalEditor, Silva Files and Images can now
          be edited using your favorite editor.

        - Bulk import of files (for File Assets) and/or images (for Image
          Assets) using a zipfile. Note though, that the 091 id
          checking is less tolerant compared to the 092 id checking.

    Bugs Fixed

        - Removed "Asset reference" asset-type stickyness.

        - Fixed button for refresh queue when Docma is enabled.

        - Added a find_indexers utility (accesible through
          http://server/silva/edit/service_utils/find_indexers) to find all
          Indexer objects in use.

        - Help text opens in new browser window.

        - Indexer -all non-versioned content actually- can now be deleted.

        - Indexer objects now render the correct URLs in virtual host
          situations. Use the 'update index' in the edit tab of Indexer
          objects to get the Indexers up to date.

        - Setting a TOC level would display one level too much.

        - Pressing 'Export' in Document's status tab now takes a user to the
          export screen of the container so the user can indeed (as the text
          suggests) export to Docma as well as download the content.

  0.9.1.4

    Bugs Fixed

        - The UI for 'Access Restriction by Role' did not properly expose
          the possibility to set this role more restrictive on a lower
          level. (the pull down menu and button would have been disabled).

        - get_public_tree() would not do the right thing with the depth-
          level control argument.

  0.9.1.3

    Features Added

        - Alternating CSS classes in table rows for external data elements.

    Bugs Fixed

        - Fixed situation where authors could not move items to other
          positions in the folders.

        - Fixed bug where no asset could be added in the asset lookup
          dialog when no previous assets where available in this folder.

        - Images nested in tables now keep their <a href="..."> tag (if set
          on the image element).

        - Ghosts of Documents containing a TOC will render this TOC with
          the Ghost's container context and not with the container context
          of the target Document.

        - Fixed unwanted aquisition behaviour of Ghost paths and other
          improvements in the Ghost code.

  0.9.1.2

    Features Added

        - Backport of the Hi-res images support.

        - Backport of the multipe file repositories ability.

        - Backport of single Document import/export.

        - Asset references and code element references will now be relative
          paths if the Assets are in the same container the Document is in,
          or in a subcontainer of this container. If not, the path will be
          an absolute path.

        - Docma queue viewer is now on both import and export screen. On
          import only Silva XML files are shown, on export only Word
          documents.

        - Export screen prefills email address and description.

    Bugs Fixed

        - Fixed some bugs with copy/cut and paste: when an object is not
          allowed somewhere, it's now not possible to paste it there
          anymore, and also the id of the object to be pasted is now
          changed until it's unique (in the past, a bug in creating a
          unique id kept the status of a document 'public' in some cases).

        - Intermediate fix where an local roles mapping for an non-existing
          userid would display "Unknown User" and could not be deleted.

        - Past to ghost of Publications exposed two bugs. Fixed now. 

  0.9.1.1

    Bugs Fixed

        - UI bug where the cursor would behave inconsistently when
          hoovering buttons and buttonlinks.

        - Membership now supports member objects that have different ids
          than the userids. This is useful in LDAP setups where the userid
          may contain characters illegal in URLs, such as the @ sign.

        - Edit on pro transformations up to date.
	  
  0.9.1

    Bugs Fixed

        - The "use selection" button would not return to tab_access 
          just after assigning a role to a user.

        - Changed from absolute_url(1) to getPhysicalPath() for 
          code elements - this should make code elements work in a
          virtual host setup.

        - Datasource parameters store empty strings instead of None
          for default values.

        - Fixed bug where the title of a SQLDatasource Asset was not 
          set in the edit tab.

        - Corrected access key in Indexer tabs.

        - Fixed tab_edit where Authors can't move anything and see
          an empty controls row.
        
        - Adjusted tab_edit and tab_status access key links so they
          work with Mozilla (select lists and checkbox labels).

        - Removed Mozilla incompatibility notes from help (since the
          problems are fixed).
        
        - Updated layout_macro to match presentation preview link in
          tab_preview.

        - Fixed location of closed message in tab_preview so it shows
          up regardless of which layout (public or default) gets used.
          Aligned presentation preview link better in default layout.

        - Fix where the Groups administration button was shown, even
          if no service_groups was available.      

        - Now refreshes all installed products before an 
          "upgrade all" action.

        - Fixed bug where a new connection id was not updated correctly 
          on the SQL Datasource Asset

        - Indexer objects now show up in public table of contents always
          if placed (before they never did).

        - File assets could only be added by users with manager role;
          this now only requires an Author role.

        - A memory leak exists in Zope 2.5.1 that is exposed by Silva in
          some cases when using the SMI. Zope 2.6.1 appears to fix this
          memory leak. Note though that while Zope 2.6.1 appears to work 
          with Silva, we haven't done extensive testing...

        - Fixed bug which cause the upgrade of all content to crash on
          CatalogedVersionedContent objects (e.g. SilvaNews NewsItems)

        - Chief editors could not add Groups or Virtual groups due to
          incorrect security settings; fixed.

  0.9.1 beta

    Features Added

        - Soft breaks in paragraphs (single enter).

        - Small API on Silva Root (add_silva_addable_forbidden() and
          clear_silva_addables_forbidden()) for absolutely forbidding
          visibility of certain meta_types in SMI. See also IRoot.py.
 
        - Improved tab_access user interface.

        - Group and VirtualGroup objects. Can be managed by going to
          'Group Administration' if Group product is installed. This
          makes group management a lot easier.

        - Optional message service ('service_message') which will send
          email on some workflow events.

        - Membership system. Different membership policies (working
          for instance with LDAP) can be plugged into Silva and
          enabled by placing a different Member Service
          ('service_members').

        - Access request system. A new UI so that users who do not
          have permissions to access a place can request roles on
          objects (optional).

        - New 'Data Source' is now enabled by default. The first
          implementation is an 'SQL Data Source' Asset. This can be
          used to import data from a relational database into a
          Document using the 'external data' element.

        - List titles have been removed and transformed into headings.
 
        - 'image_path' has been renamed to 'path' in the XML.

   Bugs Fixed

        - Fix where the "/manage" display link in the SMI tabs didn't
          didn't regard the local roles on the current object.

        - Asset reference fix where it didn't work in virtual host
          setups.

        - Fix some unicode issue related to tables (issue184)

        - Silva does no longer display non-installed content types
          in list of addables (issue159).

        - Modification time of assets should now be updated properly
          (issue147).

        - Some characters that were removed by the Silva editor
          shouldn't be removed -- made these work (issue 176).
	
        - New ('add') button should work properly again (issue 162).

        - Invalid image references now properly display error message
          (issue 204). 

  0.9.0.3

    Bugs Fixed

      - Merge from HEAD for add new object UI in tab-edit.

      - Fix where the "/manage" display link in the SMI tabs didn't
        regard the local roles on the current object.

      - Unicode fix for table rendering. Merge from HEAD branch.

      - Fix for asset reference to make it works in virtual host
        setups.

  0.9.0.2

    Bugs Fixed

      - When using LDAPUserManagement, a Attribute error on '_getOb'
        occured when adding Silva Images and -Files.

  0.9.0.1

    Bugs Fixed

      - After deleting a finished DocmaServer job, you are redirected
        to an existing page.

      - The (still disabled) externaldata element was registered wrong
        when enabled; fixed this (if you uncomment the code to enable it).
      
  0.9

    Features Added
 
        - Can change publication to folder and the reverse.

        - Links in editor now can have a 'target' option.
       
        - Images can now be hyperlinks.

        - Implementation of DataSource/DataElement for testing.

        - 'Code element' that can call arbitrary code included.
 
        - Access keys for common form buttons.

        - Integration of RealObjects editor (beta).

        - XML can be exported and imported.

        - Docma integration for importing/exporting to other document
          formats (like MS Word). This feature needs the separate
          Docma server (not yet released).

    Bugs Fixed

        - All '__index__.py' files are now non-empty, so that WinZip
          actually unpacks them...

        - Table edit bug fixed.

        - Table rendering code cleanup, better use of CSS

        - Memory leak fixed (really in ParsedXML and XMLWidgets).

        - Fix bug with wrong element-type selectors in editor.

        - Rename now provides better user feedback.

        - Definition list rendering bug fixed.

        - List rendering is now XHTML compliant.

        - Access restriction by role UI bug fixed.

        - ZMI find should now work better, thanks to bugfix in ParsedXML.

        - Lookup screen now accepts searches for people with names only
          2 characters big.

        - Lists with style no bullets are now rendered with p tag.

        - Pasted ghosts now obtain a last author.

        - Indexer is now addable by editor and up (used to be 
          manager only). Added note in UI that indexer works for published
          content only. Also fixed a bug in the Indexer; it now
          also indexes 'index' (default) documents.

        - Demo index document gets automatically added to new Silva root.

        - 'Authorized users below this level' moved to sub screen of
          access, to make container tab_metadata scale better (this
          could be very slow on large sites).
      
        - Tweaked LDAPUserFolder.py so it works with more recent versions
          of LDAPUserFolder.

        - Fixed problem in the Access tab, where the user lookup sometimes
          lost the current selection.

  0.8.6.1

    Bugs Fixed

        - RealObjects "edit-on Pro" integration improved.

        - FileSystemSite should now work on Windows install.

  0.8.6

    Features Added

       - Added Indexer object, which can find index entries and present
         them.

       - Enabled nested markup in text.

       - Added easier way to add references to files, images. Can now
         also reference assets not in local folder.

       - Ability to open/close branches of the site. Added a new
         'Viewer' role. Users with this role can see closed branches.

       - Request for approval now implemented; users can leave a message
         for the editors.

       - Added new definition list element.

       - Images now have various alignment options.

       - Moved views, widgets and other support folders to the
         filesystem, now using FileSystemSite.
