ATK/AT-SPI2 Hackfest 2012: Day 1

Hackfest

Today the ATK/AT-SPI2 Hackfest 2012 started. This time there are fewer people than last year, but we have the addition of Benjamin Otte. During the morning the main topic was global events versus per-object events. Although being simplistic the idea would be just listening to the focused object, things get complex when you start to add some practical examples, like searching. On a web page, or in GNOME Shell overview, the focus is on the text entry. But when you start to search, the content of the search result changes, and you also want to expose that. This could be solved with global-events and filtering, or with direct per-object connection to “relevant” objects. If per-object is used, it is required to decide how and with which objects, to avoid missing notifications. In any case, if we decide to keep global events, the current implementation of the global event listening in ATK seems to not be the most appropriate (as it is based on g_signal add_emission_hook, that has some problems and could be considered overkill).

During the afternoon the main topic was the removal of key grabbing in GTK, or going into more detail, deprecating gtk_key_snooper_install. The controversial part was that the code using that on the accessibility support for GTK was removed. The reason is basically that key event emission shouldn’t be done there for a lot of reasons (as we already concluded during the previous hackfest), so that removal could be justified. *But* at this moment there isn’t any alternative implemented, so several things were broken. So in the end, the conclusion was reverse that change until there is an alternative. Probably this is a good task for this hackfest (anyway, any X expert over here?).

Going to dinner can be hard

Since today was the first day, we decided to keep it simple, and try to have dinner near the hotel where most of the people are staying. So after finding that our first option was closed, and wandering around for a while, we entered a place that seemed ok. Well, typical tascas in Galicia are in general not really vegetarian friendly, and although you can find really nice places (like “Taberna Gaia”), some people can still surprise yourself. Note: it doesn’t matter if macaroni are a kind of pasta. If the sauce includes meat, it is not vegetarian. Additionally, it was a bar with TV. And although it was not too loud at the beginning, it became totally noisy when the soccer match started. Yes, we forgot about the Real Madrid-Barcelona match.

Day 2 is coming

And tomorrow there will be more. We have plenty of things to discuss and bugs to solve, so for sure it will be a busy day. Finally I want to thank Igalia, GNOME Foundation and Mozilla Foundation for sponsoring this event.

    Unfortunately XEvIE, which is deprecated and long ago removed from the X server, isn’t coming back. It was broken in kinda subtle ways when it was added, broken completely (wholly non-functional due to other input changes) when it was removed, and it’s basically unfixable in the presence of grabs.

    So you’ll have to make do with the D-Bus forwarding, I’m afraid.
