This new vfs_import plugin allows a VFS instance to be populated during
construction using a sub-VFS configured in an '<import>' configuration
node. This allows the ram_fs File_system server to be replaced by the
VFS server by reimplementing the ram_fs 'content' feature. At the
moment the copying of symlinks is not enabled, and the resources
obtained by the import file-system may not be freed after the import is
finished.
Fix#2906
The ram plugin to the VFS must send notifications to watch handles on
files when they are removed. This brings the VFS server to parity with
the ram_fs server for the sake of notifications.
Move run/fs_report to gems and use the vfs server and the vfs init
plugin in the test.
Ref #2902
This patch removes the detection of statically linked executables from
the base framework. It thereby fixes the corner cases encountered with
Sculpt when obtaining the binaries of the runtime from the depot_rom
service that is hosted within the runtime.
Statically linked binaries and hybrid Linux/Genode (lx_hybrid) binaries
can still be started by relabeling the ROM-session route of "ld.lib.so"
to the binary name, pretending that the binary is the dynamic linker.
This can be achieved via init's label rewriting mechanism:
<route>
<service name="ROM" unscoped_label="ld.lib.so">
<parent label="test-platform"/> </service>
</route>
However, as this is quite cryptic and would need to be applied for all
lx_hybrid components, the patch adds a shortcut to init's configuration.
One can simply add the 'ld="no"' attribute to the <start> node of the
corresponding component:
<start name="test-platform" ld="no"/>
Fixes#2866
This patch adds the /config/usb file to Sculpt, which allows then user
to manually define rules for assigning USB devices to clients. The
content is incorporated by the driver manager into the USB driver
configuration. Note that this mechanism does not work for HID devices
because these devices are claimed by the USB driver's built-in HID
support.
Issue #2890
This patch makes the run script compatible with the disk-image backend
of the run tool. Since this backend attaches the boot image as AHCI
disk 0, we have to supply our custom disk image as AHCI 1.
When first selecting an access point to connect to, and then - while the
passphrase entry field is displayed - switching to wired networking, the
keyboard focus was still referring to the passphrase entry field instead
of yieling the focus to the inspect window. This commit fixes the
problem by adding the wifi NIC target as additional condition.
This commit is a follow-up to "nit_fb: allow screen-relative
initial_width/height". With it, the nit_fb window created via the
launchpad can be interactively resized.
Also remove 'requires_installation_of', while also checking sbin
directories in 'have_installed'. The run scripts have been adjusted
accordingly.
Fixes#2853
The top-level Sculpt configuration is routing ROM requests for chargen
files from the input_filter to the parent, and this prevents new chargen
files to specified, for instance the German or Workman layout. Route ROM
requests with a combination of label_prefix and label_suffix patterns to
the config_fs_rom component, allowing the input_filter to be dynamically
reconfigurable.
Fix#2872
The libc will now use the file given by the 'nameserver_file' attribute
to get the DNS nameserver address instead of reading '/etc/resolv.conf'.
It defaults to '/socket/nameserver' which is the common location when
using the lxip VFS plugin. As a constraint the libc will read the first
line and expects the nameserver address without any keywords in front of
it.
Fixes#2861.
Introduce the uplink tag:
! <config>
! <uplink label="wifi" domain="uplink">
! <uplink label="wired" domain="wired_bridge">
! <uplink domain="wired_bridge">
! <config/>
For each uplink tag, the NIC router requests a NIC session with the
corresponding label or an empty label if there is no label attribute.
These NIC sessions get attached to the domain that is set in their
uplink tag as soon as the domain appears. This means their lifetime is
not bound to the domain. Uplink NIC sessions can be safely moved from
one domain to another without being closed by reconfiguring the
corresponding domain attribute.
Attention: This may render previously valid NIC router configurations
useless. A domain named "uplink" doesn't automatically request a NIC
session anymore. To fix these configurations, just add
! <uplink domain="uplink"/>
or
! <uplink label="[LABEL]" domain="uplink"/>
as direct subtag of the <config> tag.
Issue #2840
With this patch, the sculpt manager takes over the role the window
layouter of the leitzentrale, which eliminates the need to manually
position and size the inspect window.
This patch suppresses the start of components that cannot run because
obvious runtime dependencies (used servers) are missing in the runtime.
In this situation, the sculpt manager gives diagnostic feedback to the
user in the runtime dialog.
Sculpt's discovery of the default storage target can be intercepted by
user input (i.e., pointer movements) at boot time. The patch makes this
intervention mechanism robust for the case where nitpicker's first hover
report arrives after all storage devices were already scanned.
By tracking the states for an interactive selected NIC target (managed)
and a manual-defined NIC target (config/nic_router) separately, the
sculpt manager becames able to present the user with the ability to
interactively disable and re-enable a manually-managed network
configuration.
The sculpt manager wrongly paid for the nitpicker session of the fader
out of its own pocket. This patch reduces the quota transfer to the
amount provided the fader.
When updating the GPT to match the underlying block device, the
protective MBR will normally also be updated. In case a hybrid MBR is
used, as is done if 'image/disk' is specified, setting the
'preserve_hybrid' flag will prevent the component from overriding the
MBR.
This commit updates Early-Adopters (EA) version of Sculpt to the version
for The Curious (TC). Most importantly, it contains the new interactive
sculpt-manager component that automates many system management and
configuration tasks.
This patch enhances the 'Child' interface with the ability to retry the
deployment after an initial attempt failed. This way, packages can be
installed on demand based on the error feedback of deployment attempts.
The state report reflects the progress of downloading, verifying, and
extracting archives. For the download step, it includes the progress
as reported by fetchurl.
This patch changes the button widget to apply the vertical offset to its
child widgets at draw time, not at the layout phase. This way, the
visual feedback on button press/release changes is more direct because
it sidesteps the geometry animation.
Rename LwIP library in preparation for removal of LwIP libc plugin. The
current LwIP library will be replaced with a new version stripped of its
synchronous socket support. The next version will be incompatible with
the current, so removing 'lwip.lib.so' completely for a period makes it
easy to identify legacy users.
Fix#2797
This patch enhances the box layout such that child widgets are
equally stretched to the available size whenever the box layout's
size is larger than its min size. Furthermore, it corrects the
mixed-up use of the terms east and west in the float widget.
This component creates a GPT on a Block device. It supports the common
actions, as in adding, deleting and modifying entries in the GPT, while
considering alignment constraints. If needed it will round the length of
a partition down to meet those constraints. The component will not
perform layout checking, i.e., it does not care about overlapping
partitions. Only when apping a partition it will make sure that the
partition will fit.
Please read _repos/gems/src/app/gpt_write/README_ for more detailed
information on how to use the component and feel free to check out
_repos/gems/run/gpt_write.run_.
Fixes#2814.
The box-layout widget used to trigger the geometry animation of its
children immediately when updating the widget from the XML model (by
calling 'child->Widget::geometry'). This caused layout inconsistencies
in situations where the box layout is defined not by the constraints of
the child widgets but from the outside (the parent calls Widget::size).
Since the final layout is not known before the parent defines the actual
size, this patch moves the trigger point for the geometry animation to
'Widget::size'.
The new 'version' attribute can be used to explicitly distinguish
widgets that have the same name. E.g., if one widget is removed and
another with the same name is created somewhere else at the same time,
the menu view would normally interpret this change as a movement.
By attaching a distinct 'version' the new instance, menu view won't
attempt perform a smooth transition between the old and new widgets.
This patch addresses the corner case where hovering changes while a
button is held, e.g., when accidentially moving the pointer out of a
application window's area during a drag-and-drop operation. The patch
makes the window manager aware of the drag/idle state. Only when idle,
the pointer position is propagated to the decorator now.
This commit changes the 'Input::Event' type to be more safe and to
deliver symbolic character information along with press events.

By incorporating the sculpt version into the path where customizations
are stored, we can update and roll back sculpt versions without risking
configuration incompatibilities. By default, the sculpt version
corresponds to <genode-dir>/VERSION.
The condition must first check the io-buffer length and then check the
content. Otherwise, cat'ting a file that is padded with zeros up to
page size (io-buffer size) yields an out-of-range read access.
This patch replaces the terminal's formerly built-in fonts with the new
VFS-based font handling.
To avoid the copying of the terminal's font configuration across run
scripts, this patch adds the new terminal/pkg runtime package, which
includes everything needed for instantiating a terminal: the actual
terminal component, the library dependencies (vfs_ttf, which in turn
depends on the libc), a font (bitstream-vera), and a reasonable default
configuration.
Fixes#2758
VFS plugin to replicate from one file-system to another. Can be used to
seed a mutable file-system with an immutable file-system. The plugin is
configure with two paths, a read-only path, and a read-write path. This
is an initial implementation that copies files on open. It is not
optimized to perform actual copy-on-write, but the result is the same.
<vfs>
<dir name="immutable"> ... </dir>
<dir name="mutable"> ... </dir>
<dir name="cow">
<cow ro="/immutable" rw="/mutable"/>
</dir>
</vfs>
Fix#2745
Reduce the size and forward compatibility of VFS file-system
constructors by passing an object holding accessors for 'Genode::Env',
'Genode::Allocator', response handlers, and the root file-system.
Fix#2742
A ring buffer that uses a single dataspace mapped twice in consecutive
regions. This allows any operation that is less or equal to the size of
the buffer to be read or written in a single pass. The capacity of
Magic_ring_buffer is defined at runtime.
Fix#2725
This commit introduces a VFS plugin that exposes the glyphs and
metadata of a TrueType font as a pseudo file system. The TTF font data
is obtained from the VFS. The resulting pseudo file system is a
directory that contains the files 'glyphs', 'baseline', 'max_width',
and 'max_height'.
The counter part of the plugin is the 'Vfs_font' class that implements
the 'Text_painter::Font' interface by accessing the pseudo file system
as provided by the TTF VFS plugin.
Fixes#2740
This patch enhances the VFS access utilities of gems/vfs.h to be usable
with a prior created root directory. It also adds a
'File_content::bytes' method for operating of the raw content, which is
needed in situations where the data pointer is passed to a third-party
parser.
This patch improves the `Text_painter` utility that is commonly used by
native Genode components to render text:
- Support for subpixel positioning
- Generic interface for accessing font data
- Basic UTF-8 support
Since the change decouples the font format from the 'Text_painter' and
changes the API to use the sub-pixel accurate 'Text_painter::Position'
type, all users of the utility require an adaptation.
Fixes#2716
This patch enables the use of the VFS from VFS plugins by passing a
reference of the root directory to the constructors of file-system
instances. Since it changes the signature of 'Vfs::Dir_file_system',
any code that uses the VFS directly requires an adaptation.
Fixes#2701
The visibility of the client's view is re-evaluated at each animation
step. However, when the client appears long after the initial
fade-in/out animation is completed, the initial visibility state
remaines unchanged. This happens when booting the Sculpt scenario in
Qemu where the the nit_fb instances of the leitzentrale could not be
started in time. This patch fixes the issue by re-evaluating the view
visibility also at the view-creation time.
We need to update the blueprint pkg path as well in case the start node
is changed. Otherwise the query tool will keep using the initially
configured pkg path.
