Mark Doffman gave a brief overview of the specs and code tree. There has been a 300% increase in the number of people familiar with the project code-base. ===== API Crawl ===== As a group we did a review of the D-Bus specification referring to the CORBA IDL specification and the code. A number of inconsistencies were found and resolved including: * Passing of Attributes as a string rather than dictionary. * Enums vs ints. * Removed dead / unused API. * Fixed bugs in pyatspi where return-values were not marshaled as requested in the specification. * Fixed bugs in pyatspi where non-writable properties had 'write' methods. ===== Orca-based sanity check ===== As a group we tested AT-SPI D-Bus with Orca & gtk-demo. This brought up a number of previously un-discovered bugs which were resolved. ===== Remaining work ===== We discussed the work remaining and created a list of known problems and issues. * Migrate AT-SPI changes made since project branch (04-2008). (1 week) * CBindings (Unknown) * Complete cspi API not-necessary. C Bindings should be provided for the accessible-transfer and caching mechanisms. * Possibly gok will need re-writing or porting to the new API. * Possibly implement Collections API on the client side. (4 weeks) * Atk adaptor library does not handle containers with state MANAGES_DESCENDANTS. * Gail changes can remove MANAGES_DESCENDANTS from the GailTreeView ATK implementation. (DONE) * MANAGES_DESCENDANTS could be used to handle very large containers. Don't cache any children of a MANAGES_DESCENDANTS container. The container handles all of their method calls. (3 weeks) * Interfaces for dealing with 'infinite space' containers. (Unknown) * Discuss with D-Bus developers whether we should create an "X Session" bus for the purpose of accessibility. The purpose of this is to allow multi-user accessibility. (Dependency on external team, this change is a goal for Gnome 3.0 in general.) * Discuss the 'Login Helper' interface with Jon McCann. This interface was previously part of the AT-SPI specification. * Implement a login-helper registry as part of the AT-SPI registryd. (2 days) * Requires changes in GOK. * Requires changes in screen-saver. * The Device Event Controller makes synchronous method calls blocking the application that notified it of the event. This can cause deadlock. * Modify the 'notifyEvent' call in the atk-adaptor to be re-entrant. (DONE) * Pyatspi makes blocking function calls. This will cause deadlock when an AT attempts to access accessibility information about itself. For example, Orca cannot access its own preferences GUI. * Make all pyatspi D-Bus method calls re-entrant. (1 week with some external dependencies on python-dbus developers) * New infrastructure needs to be integrated into the Gnome desktop. * The registryd start-up process needs to be looked at. This includes the possibility of using DBus activation. * A JHBuild module-set needs to be created for the project. (1 week) * Gnome approval of external dependency for AT-SPI 2. * Create documentation of the protocol / pyatspi API. D-Bus XML to HTML conversion. (1 week) * Performance testing and improvements. (3 months) * Improving test coverage and bug fixing. (6 months) * Java access bridge needs converting to use the JNI and ATK adaptor. (4 months)
