TracGViz 1.3.1

Assertions concerning permissions are supported, but not directly. They are delegated to the underlying layers on top of which the data sources have been implemented (e.g. XML-RPC handlers).

GadgetLinksDispatcher has been renamed. Now it is known as LinksTreeDispatcher. It supports multiple root namespaces (i.e. so far gadgets, and gviz) as well as the former hierarchy of links.

IGadgetTracLinksResolver now is known as ITracLinksItem interface. From now on its get_link_resolvers method has to return the name of the root namespace (e.g. gviz).

New ! TracLinks expressions for Google Apps Reporting Visualization API have been implemented. It may be necessary to be logged in to the Google Apps control panel in order to access the data. Syntax -> gviz:google:apps:<report_key>@<report_date>:<domain>[?tq=<query>]

New ! It is possible to make reference to Google Spreadsheets using TracLinks expressions starting with gviz:google:sheet: prefix. They also support range attribute -to select only specific cells- and headers option -in order to specify how many rows are header rows-. Syntax -> gviz:google:sheet:<sheet_id>[:<top_cell>-<bottom_cell>][?headers=<number>]

New ! It is possible to make reference to Google’s standard visualizations using TracLinks expressions starting with gadget:google:modules: prefix. Syntax -> gadget:google:modules:<chart_name>

TracLinks expansion for custom arguments in iGoogleGadget macro is not a dream anymore. You can enclose TracLinks expressions in brackets and assign such values to custom arguments. In such cases the macro will perform the expansion looking for the target URL. Hence the first expression shown below can be written now as shown in the second example. Both of them will embed in the wiki page a motion chart displaying the data found in cells B3-G17 inside Google Spreadsheet number 1234.

[[iGoogleGadget(url=http://www.google.com/ig/modules/motionchart.xml, _table_query_url=http://spreadsheets.google.com/tq?range=B3%3AG17&key=1234, _table_query_refresh_interval=5)]]

[[iGoogleGadget(url=gadget:google:modules:motionchart, _table_query_url=[gviz:google:sheet:1234:B3-G17], _table_query_refresh_interval=5)]]

All links to third-party sites resulting from expanding a TracLinks expression are rendered in wiki pages with the well-know icon []->.

Instances of GVizXMLRPCAdapter now can implement the method xmlrpc_namespace. It is similar to the former gviz_namespace method, but returns the XML-RPC namespace. This way multiple data sources can be implemented using the services provided by a single XML-RPC component.

New ! GVizSearchFiltersProvider now allows to list all search filters installed in a Trac environment.

New ! It is possible to document the parameters accepted by a data source using gviz_param decorator.

GVizProviderList macro now displays the parameters accepted by data providers.

Now it is much easier to handle unicode, date & time and values returned by the different data sources. From now on there is no need to convert instances of xmlrpclib.DateTime in to instances of datetime.date*

New ! GVizSearchProvider now gives access to search results returned by Trac built-in search engine. You can specify a query string and control the search filters (e.g. wiki, ticket, milestone, pydoc) in use.

New ! You can get the names of the actions that can be performed on a given ticket using ticket/actions data source.

New ! You can get all the meta-data describing ticket fields by accessing ticket/fields data source.

New ! GVizTicketChangeLog provides a detailed changelog in order to know the modifications made to different tickets. The data source is available at ticket/log.

New ! GVizTicketAttachments provides detailed information about the files attached to different tickets. The data source is available at ticket/attachments.

New ! GVizTimelineFilters provides detailed information about the different filters offered by those sources contributing to the timeline. The data source is available at timeline/filters.

New ! GVizTimelineEvents provides detailed information about the timed events reported by those sources contributing to the timeline. It supports time slicing, and filtering. The data source is available at timeline/log.

GVizMilestoneProvider has been enhanced. Formerly it just offered the milestone name, due and completed time, plus its description. Now it also contains some statistics on groups of tickets like those displayed in the roadmap views. This includes the amount of work that’s been done, the units used to measure the indicators, percent of the whole work that’s been already done, the number of active and closed tickets, and the percent they represent with respect to the total number of tickets.

New ! GVizWikiPages provides detailed information about the wiki pages found in the Trac environment. It supports multiple features, being timed filters, page selection and multiple versions, just a few of them. The data source is available at wiki/index.

New ! GVizWikiAttachments provides detailed information about the files attached to wiki pages found in the Trac environment. The data source is available at wiki/attachments.

The right MIME type (i.e. application/json) is sent back to the client in the HTTP response when JSON is requested. This is consistent with RFC xxx.
