The screenshot trigger displays a little red dot at the upper-left
corner of the screen. When touched or clicked-on, it generates an
artificial key-press-release sequence for the print key and disappears
for one second. In this time, a separate screenshot component can handle
the print key by capturing the screen without the red dot appearing in
the saved picture.
The touch-keyboard config accepts the new attributes 'opaque="yes"
and 'background=#112233' to control the dialog background. The
attributes are passed unmodified to embedded the menu view.
This patch add the support needed for implementing on-target
system-update functionality. The new 'empty' method is required for the
two-step procedure of updating image-index files - removing the old
index, followed by downloading the most current one. It is used to the
detect the completion of the first step.
Issue #4744
This patch reflects more details such as the percentage value for
downloads maintained in the download queue. This makes this information
easier to display at the GUI.
Issue #4744
This patch replaces the generic "In progress..." message by slightly
more concrete information about the type of operation. This is useful to
distinguish the two steps during the expansion of a partition.
This patch enhances the depot_download subsystem with support for
downloading and querying system images.
The installation ROM support the following two now download types:
<image_index path="<user>/image/index"/>
<image path="<user>/image/<name>"/>
Internally, the depot-download subsystem employs the depot-query
component to determine the missing depot content. This component
accepts the following two new queries:
<images user="..."/>
<image_index user="..."/>
If present in the query, depot_query generates reports labeled as
"images" and "image_index" respectively.
The also tracks the completion of each job depending on the depot-
query results, so that the final report contains a result for each
installation item requested. Prior this patch, the inactivity of the
depot-download manager (indicated by an empty state report) was
interpreted as success. But that prevents the proper association of
results and requested installation items.
Issue #4744
The 'scan' query for depot users used to list the names of depot users.
However, the URL and existence of a pubkey is useful to know when
assembling a GUI menu from this list.
Issue #4744
Each time when enlarging the menu view, a new 'Gui_buffer' is
constructed with the new size. At its contruction time, the default
reset background color is in effect, which is evaluated by
'reset_surface' as part of the construction. A custom reset color
takes effect only after the construction. Hence, when the Gui_buffer is
flushed to screen immediately at construction time, the gray default
becomes visible for a short time.
This patch changes the Gui_buffer to accept the reset background color
as construction argument so that it takes immediate effect.

With the new 'presets:' tag, .sculpt files can now refer to deploy
configurations to be integrated in the presets/ subdirectory of the
config file system. Those files can thereby be used as preconfigured
system scenarios. Such a preconfigured scenario can be loaded at
runtime by copying the preset file to config/deploy.
Issue #4731
This patch simplifies the 'Deploy::update_managed_deploy_config'
interface by keeping an internal copy of the currently used deploy
template inside the 'Deploy' class. The template is updated whenever
the config/deploy file is modified.
This change weakens the coupling between the '_manual_deploy_rom' and
the '_deploy' subsystem, easing the upcoming implementation of the
switching between presets.
When writing the GPT header, the tool always wrote the GPT entries
belonging to the primary header to LBA following the header. Normally
this is LBA 2 as the header is located in LBA 1. The GPT allows for
up to 128 entries that all in all cover 16 KiB of storage space.
However, on some systems, e.g. ARM-based machines, the bootloader can
be stored in this region. For this reason the GPT entries may be moved
to a different LBA.
This commit changes the tool to adhere to then given GPE LBA in header
when writing out the modified GPT data.

The old 'Io_response_handler::io_progress_response' interface has been
replaced by the 'Vfs::Env::User::wakeup_vfs_user' (issue #4697). The
remaining 'read_ready_response' method is now hosted in the
appropriately named 'Read_ready_response_handler'.
Issue #4706
This patch keeps driving the internal state machines until no progress
can be made. This required fixing the return values of several execute
functions, which used to report progress while being in complete state.
Along the way, the patch removes default switch cases to ensure that all
states are covered.
Issue #4706
By adding a 'write_ready' interface following the lines of the existing
'read_ready', VFS plugins become able to propagate the (de-)saturation
of I/O buffers to the VFS user. This information is important when using
a non-blocking file descriptor for writing into a TCP socket. Once the
application observes EAGAIN, it expects a subsequent 'select' call to
return as soon as new I/O buffer space becomes available.
Before this patch, the select call would always return under this
condition, causing an unnecessarily busy write loop.
Issue #4697
This patch removes the 'Insufficient_buffer' exception by returning the
WRITE_ERR_WOULD_BLOCK result value instead. It also eliminates the
superfluous WRITE_ERR_AGAIN and WRITE_ERR_INTERRUPT codes.
Issue #4697
This patch fosters the batching of network packets transferred by the
lwIP stack over the NIC connection. It replaces the eager submission of
the packet-stream's data-flow signals by explicit wakeup notifications.
The commit also increases the NIC session's buffer size from 128 to 1024
packets.
Issue #4697
This patch facilitates the batching of I/O operations in the VFS library
by replacing the implicit wakeup of remote peer (via the traditional
packet-stream interface like 'submit_packet') by explicit wakeup
signalling.
The wakeup signalling is triggered not before the VFS user settles down.
E.g., for libc-based applications, this is the case if the libc goes
idle, waiting for external I/O.
In the case of a busy writer to a non-blocking file descriptor or socket
(e.g., lighttpd), the remote peers are woken up once a write operation
yields an out-count of 0.
The deferring of wakeup signals is accommodated by the new 'Remote_io'
mechanism (vfs/remote_io.h) that is designated to be used by all VFS
plugins that interact with asynchronous Genode services for I/O.
