Ref #3848
This patch prevents nitpicker from requesting a framebuffer and input
session by default because the regular use of nitpicker relies on the
capture-session and event-session interfaces by now.
For supporting the nested use of nitpicker via the gui_fb component, it
is still possible to enable the traditional behavior by explicitely
setting the 'request_input' and 'request_framebuffer' config attributes
to "yes".
Issue #3812
This remove the call to Io_progress_handler::handle_io_progress() from
wait_and_dispatch_one_io_signal() to prevent unexpected nesting
I/O-progress handling in case of custom dispatch loops (e.g., in libc).
The original intention of Io_progress_handler was to inform the
entrypoint just before blocking in the entrypoint loop.
Issue #2635
This commit applies the transition from the "Input" session to the "Event"
session to the event-filtering mechansim. The functionality of the
input_filter is now provided by the event_filter. The event filter
requests only one "Event" session as destination for the filter result,
which is usually routed to the nitpicker GUI server. It provides an
"Event" service to which any number of event sources can connect.
The configuration of the filter chain remains almost the same. Only the
declaration of the <input> nodes is no longer needed. Instead, the
configuration must specify <policy> nodes, which define the mapping of
"Event" clients (event sources) to the inputs used in the filter chain.
The patch adjusts all uses of the nitpicker GUI server accordingly such
that the event filter reports events to nitpicker's event service
instead of having nitpicker request an "Input" session. This dissolves
the dependency of nitpicker from input drivers.
Issue #3827
This patch brings the input filter into a shape that is easier to
re-mold into an event filter, reversing the client/server roles of
the component.
* The 'Sink &destination' is no longer passed as constructor argument
to the individual filters but passed as argument to the 'generate'
method. This way, the final destination does not need to exist at
the construction time of the filter chain but can be created on
the fly (clearing the way for using 'Event::Client::with_batch').
* A new 'Source::Filter' interface with the 'apply' method aids the
cascading of filters during 'generate'. The modules now implement
the 'Source::Filter::filter_event' interface instead of the
'Source::Sink::submit_event' interface.
* Since the 'Sink &destination' is no longer a member of the filter
modules, character-repeat events can no longer be emitted in an
ad-hoc way. Instead, the character-repeat mechanism now invokes
a new 'Trigger::trigger_generate' hook that prompts the execution
of the regular 'generate' mechanism by the main program.
This patch is supposed to leave the semantics of the input filter
unchanged (validated by the input_filter.run script).
Issue #3827
This is an intermediate helper component for the transition of input
servers into event clients. It works analogously to the
input_event_bridge but it connects servers instead of clients.
In particular, it can act as glue between a traditional input driver
that provides an input service and the event filter that provides an
event service. Thanks to this component, each driver can be migrated to
the event-client interface individually.
