This patch fixes the corner case where an animated geometry changes its
destination mid-way while an animation is already in progress. The
'_trigger_animated_geometry' method used to back out early in this case,
which was intended as an optimization.
Fixes#3296
This enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.
Fixes#3208
As a preparatory step for introducing the new block-client API, we have
to turn the 'Block::Connection' into a class template. The template
argument will be used to tie an application-defined job type to the
block connection.
Issue #3283
This patch replaces the formerly fixed 2 KiB data alignment within the
packet-stream buffer by a server-defined alignment. This has two
benefits.
First, when using block servers that provide small block sizes like 512
bytes, we avoid fragmenting the packet-stream buffer, which occurs when
aligning 512-byte requests at 2 KiB boundaries. This reduces meta data
costs for the packet-stream allocator and also allows fitting more
requests into the buffer.
Second, block drivers with alignment constraints dictated by the
hardware can now pass those constraints to the client, thereby easing
the use of zero-copy DMA directly into the packet stream.
The alignment is determined by the Block::Session_client at construction
time and applied by the Block::Session_client::alloc_packet method.
Block-session clients should always use this method, not the 'alloc_packet'
method of the packet stream (tx source) directly. The latter merely
applies a default alignment of 2 KiB.
At the server side, the alignment is automatically checked by
block/component.h (old API) and block/request_stream.h (new API).
Issue #3274
This patch modernizes the 'Block::Session::info' interface. Instead of
using out parameters, the 'init' RPC function returns a compound 'Info'
object now. The rather complicated 'Operations' struct is replaced by
a 'writeable' attribute in the 'Info' object.
Fixes#3275
The 'aes_cbc_4k' library is simple wrapper around libsparkcrypto to
serve as a backend for storage encryption. It operates on data chunks of
4 KiB and uses AES-CBC while incorporating the block number and the
private key as salt values.
Replace the I/O response handler that is passed to the VFS at
construction with an object that is dynamically attached to handles.
This object shall also accept read-ready notifications, and plugins are
encouraged to keep handles awaiting ready-ready notifications separate
from handles that await I/O progress.
Replace the use of handle lists in plugins with handle queues, this
makes the code easier to understand and the ordering of notifications to
the application more explicit.
These changes replace the use of the Post_signal_hook from all VFS
plugins, applications must assume that read-ready and I/O notifications
occur during I/O signal dispatch and use an Io_progress_handler at its
entrypoints to defer response until after signal dispatching.
Fix#3257
The '_currently_constructed' pointer caches the information about which
'Launched_child' is currently configured in the menu. When discarding
the runtime (e.g., when un-using a file system) at this point, this
cached pointer was not invalidated while all 'Launched_child' objects
would be freed (including the currently constructed one). On the next
attempt to construct a new child, the sculpt manager attempted to
destruct the 'Launched_child' referred by the (now outdated)
'_currently_constructed' again.
Fixes#3240
This commit handles the corner case where a package could be installed
successfully but the package's runtime definition is inconsistent with
the content delivered by the package's dependencies, i.e., the <content>
of the runtime file lists ROM modules that do not exist.
With this patch, the '+' menu shows the message "installed but
incomplete" whenever a package is in such a state.
Issue #3241
The "Vfs::Vfs_handle" type should not contain any public members that
can be initialized by the VFS internally and by the application, so
remove inheritance from the "Genode::list::Element" class. The VFS
plugins must instead use lists of "Vfs::Vfs_handle" sub-classes, the
lifetime of which are always managed by the plugin.
Ref #3036
It turns out that the commit "window layouter: allow floating apps to
resize" interplays badly with the interactive toggling of the maximize
state of windows. In contrast to the window geometry and stacking, which
is always updated through the rules-feedback mechanism, interactive
changes of the maximize state omitted this loop and instead took a local
shortcut. Because of this shortcut, the maximized geometry eventually
ended up as window size in the window's assign rule. So unmaximizing the
window failed to revert the geometry to its original state.
This patch removes this inconsistency. The maximize state adheres to the
official chain of commands through the rules mechanism now. The state is
now maintained internally without affecting the window's geometry and is
evaluated while generating the window layout only.
As a minor loosely related improvement, this patch prevents the
highlighting of resize handles for non-resizable windows.
Issue #3200
This patch improves the transition from an interactive window geometry
change (dragging a window element) to the point where the resulting
new layout rules come into effect. During this short time, no resize
request must be issued because such a resize request would be based on
stale rules.
Fixes#3227
This is a follow-up commit to "Update <provides> info in pkg runtimes",
which adapts the users of the wm pkg to the changed label of the "focus"
nitpicker session.
This patch gives applications the ability to control the size of their
window whenever the window is floating, not tiled or maximized. See the
comment in the code for the rationale.
Fixes#3200
The default rate of 100 ms keeps Sculpt too busy because the menu that
displays the percentage values is drawn completely on each update.
Limiting the rate to 1/4 seconds relieves the effect.
By clicking on a yellow checkbox in the depot selection dialog, the
corresponding index files are removed. This way, index files can
be update by removing and downloading them again.
This patch also filters out sculpt-managed components from the graph to
avoid erratic graph-position changes while the '+' menu is open.
Fixes#3193
The fs_tool component performs file operations according to its
configuration. This initial version implements only the operation
<remove-file> as needed for Sculpt CE.
Issue #3222
Issue #3193
This patch refines the criterion of when the networking is considered as
ready to use. Until now, any IP reported by the NIC router was taken as
an indicator for connectivity. But as the NIC router reports an IP
0.0.0.0/32 when no network cable is plugged at the uplink, the condition
was too loose.
This patch improves the error handling of depot-download manager for the
case where a download is requested but the corresponding software
provider information is absent from the depot. Without this patch, the
update mechanism would get stuck in the failed depot-query step and
won't attempt to perform subsequent download jobs.
Fixes#3224
The storage dialog is folded when activating the runtime view (e.g., by
clicking on the Genode Logo). This should happen immediately as response
of the mouse click.
This patch improves the separation of the update and layout phases to
avoid superfluous geometry animations of its child widgets. Prior this
patch, 'Widget::geometry' was called in both phases, potentially
triggering geometry animations with intermediate values at the update
phase.
Related to issue #3221
The button widget already supported an animated transition between
hovered and unhovered states. This patch generalizes the mechanism to
allow animated transitions between arbitrary button states, including
style changes.
This way, the fade-out of non-TCB components in Sculpt CE happens not
abruptly but smooth.
Fixes#3221
The default 'Rect' constructor constructs an invalid rectangle where the
p1 coordinates are lower than the p2 coordinates. In particular, p1 is
set to (1, 1). The 'Widget' implementation uses the points individually
as input into the 'Animated_rect' mechanism. This way, widgets end up
being positioned at (1, 1) initially and are moved to (0, 0) once the
first layout update is applied. By explicitly initializing the
'_geometry' to (0x0+0+0), we avoid this initial artifact.
When entering/leaving sub menus of Sculpt's '+' menu, some parts of the
menu sometimes remain unchanged, in particular the back button.
Originally, a click would reset the hovering on clicks in the
expectation that any click would eventually result in a completely new
situation where the old hovering information does not make sense and
would only (potentially) confuse the menu. But this was apparently
overzealous. With the patch a once hovered back button stays hovered
even when actitivated and the back button of the upper-level menu
happens to stay under the current pointer position.
Issue #3209
This patch improves the hover handling in situations where the dialog
changes under the pointer. Previously, hover changes were reported
as response to user input only, which failed to cover this case. This
became a problem with Sculpt CE's '+' menu, which changes on the fly
when entering/leaving sub menus.
The patch also cleanly separates the hover handling from the focus
handling. Originally, the hovering was reset when the menu view got
unfocused. In situations like Sculpt's '+' menu where the menu view
receives a transient focus only while clicked and gets unfocused on the
button-release event (aka clack), each clack would invalidate the hover
information until a new input event comes in.
Finally, the patch introduces the clear distinction between situations
where the entire dialog is hovered or not. Previously, this state was
somehow implicitly kept by issuing an invalid hover report whenever a
leave event was observed.
Issue #3209
When a window is moved, the virtual pointer position must be updated,
taking the changed input coordinate into account. This patch propagates
such changes via absolute motion events to the client.
Without this patch, Sculpt CE's '+' menu wouldn't update the hovered
item correctly when entering/leaving sub menus (which happen to trigger
the repositioning of the menu on screen).
Issue #3209
When specifying the attribute 'dep_visible="false"' for a primary
dependency or the attribute 'visible="false"' for a secondary
dependency, the dependency is used for the layout calculation but not
displayed in the graph.
- Omit showing routes to uninteresting ROMs obtained from the parent,
i.e., the binaries requested by the sculpt-managed subsystems.
- Change the routes for the inspect subsystem such that the inspect-noux
instance is anchored at the config node (critical!) and the nit_fb
instance anchored at the used GUI.
This patch excludes the current "Construction" from the list of
"present" components in the runtime. Without the patch, a missing "wm"
would go unmissing once when the routing dialog of a new wm instance
appears. Now an already present window layouter that had a broken route
would prematurely re-appear in the config, which should not happen
because the new wm does not exist yet.
When buiding the sculpt image, the sculpt.run script used to integrate
the current version of the index of the 'depot_user' into the boot
image. At runtime, when the Sculpt partition is selected for "use" this
index - along with the 'pubkey' and 'download' files of the known
depot users - is written to the Sculpt partition.
This has the undesirable effect that a later version of the index
(published some time after the sculpt image was created) would always be
overwritten by the outdated index shipped with the boot image.
The built-in default index was actually a stop-gap solution needed
during the development of Sculpt CE, introduced when the downloading of
index files was not yet supported. Now, with the working download
mechanism, it is no longer needed. Hence, this patch removes the default
index from the sculpt image.
This commit removes most of the default launchers, which are now
superseded by the interactive component addition feature of the '+'
menu.
We keep the chroot components because we cannot easily create chroot
instances interactively yet.
The usb_devices_rom is still needed because its configuration is meant
to be edited at runtime.
It also adds a 'themed_wm' launcher to make the initial sculpt
experience easier. For knowledgeable users, the index contains all
ingredients needed to build a multi-component window manager manually.
This commit turns the '+' menu into a tool for the following tasks:
- Selecting and downloading of depot index files
- Browsing of the hierarchical depot index files
- Installation of packages found in the index files
- Interactive routing configuration of a selected package
- Deployment of configured component
Sculpt used to restrict the size of leitzentrale windows to the screen
area that is not obstructed by the menu and log. This is useful for the
runtime view and the inspect window. However, the menu should be allowed
to use the entire screen because it overlays the other content.
Before this patch, the menu wouldn't be displayed completely on small
resolutions (e.g., 1024x768 when using the VESA driver) because the log
at the bottom of the screen imposed the size constraint on the menu.
With the patch, the menu is able to overlay the log window.
This patch enhances the runtime view such that not only immediate
dependencies but also all transitive dependencies of the selected
component are displayed. This way, the graph nicely reveals the
trusted computing base of the selection.
Instead of parsing the runtime's configuration each time when generating
the graph dialog (e.g., when changing the hover state), extract the
relevant information only on configuration changes.
The runtime view, launcher query, and depot query increase the
complexity of the graph without providing a tangible value to the user.
This patch omits those components from the runtime view to make the
graph less confusing.
Append "..." to button labels whenever the button does not perform an
immediate action but merely toggles user-interface elements. This
tells the user that the button can be pressed without risk.
With this commit, the 'installation' input of the depot-download
subsystem accepts <index> nodes in addition to <archive> nodes. Each
index node refers to one index file specified via the 'path' attribute.
This commit also improves the tracking of failure states. Once an
installation job failed (due to a download of verification error),
it won't get re-scheduled. In the past, such failure states were not kept
across subsequent import iterations, which could result in infinite
re-attempts when an installation contained archives from multiple users.
The the progress of the download process is now reflected by the
"progress" attribute on the download manager's state report, which
allows the final report to contain the list of installed/failed archives
along with the overall progress/completed state. The detection of the
latter is important for the sculpt manager for reattempting the
deployment of the completed packages.
The patch enhances the depot_download.run script to stress the new
abilities. In particular, the scenario downloads a mix of index files
(one present, one missing) and archives, from two different depot users
(genodelabs and nfeske).
Issue #3172
The input for the pkg index is located at gems/run/sculpt/index.
The sculpt.run script uses this input for generating the depot index
file at depot/<user>/index/<version>.
The tool/depot/publish tool support arguments of the form
<user>/index/<version> where <version> corresponds to the Sculpt
version.
Issue #3172
This prevents the situation where the user has booted the system, has
not yet selected a storage target to "use" for Sculpt, yet clicks on the
'+' menu. Such clicks show no immediate response because Sculpt cannot
know where to deploy the selected package. But since the user is not
guided towards resolving this prerequisite, it's better to not present
the menu in the first place. The '+' appears as soon as a storage target
is selected for "use".
This error message may occur during the startup of a multi-component
application when the very first dialog is generated just after the menu
view is ready. It is not an error.
This commit adds the following styles:
button/enter - for entering a sub menu
button/back - for returning from a sub menu
button/radio - for picking one item of a list
button/checkbox - for making a selection
frame/transient - for temporary GUI elements
This message is diagnostic, but also occurs in legitimate situations
such as the wm in Sculpt's Leitzentrale where the focus is managed
completely outside the wm.
The zynq nic_drv also depends on hw, we therefore adapted the folder
structure for clarity. Also renamed the binary to 'zynq_nic_drv' to
prevent conflicts and to allow removing the cadence_gem spec.
Issue #3179
This patch simplifies the propagation of pointer shapes from
window-manager clients to the pointer. The "shape" report is routed to
the wm server, which, in turn, reports it to the pointer. This way, the
pointer can easily correlate the label of the application's "shape"
report with the label of the application's Nitpicker session. The
formerly used manual rewriting of the "shape" label is not needed
anymore.
Since the wm server provides a "Report" service now, its <provides>
declaration must cover "Report" in addition to "Nitpicker" to avoid
runtime error messages. Vice versa, the wm is now expected to request
"shape" reports, which should be routed to the pointer (using the
'label_last' routing attribute).
Fixes#3165
Refactor the graphical terminal server to internally represent
characters as 16-bit codepoints and handle the duplex terminal stream as
UTF-8.
- Make the Codepoint class printable to the Output interface
- Decode data received at the Terminal session from UTF-8 to a 16-bit
character
- Pass 16-bit characters through terminal decoder and char-cell arrays
- Send Unicode through terminal session in a burst of UTF-8 bytes
Fix#3148
The minimal-footprint Ada runtime for implementing library-like
functionality in SPARK is now called "spark" runtime.
The full Ada runtime for entire components written in Ada and using the
libc as glue to the underlying system will move to the world repository
as "ada" runtime.
Issue #3144
The 'run_genode_until' procedure only called 'run_power_on' to reset
the target machine. That works will with the softreset module, which
is used by all x86-based test system but falls short regarding ARM
boards. The way those boards are connected requires turning the power
off and on for a complete cycle.
The situation where a 'Session_policy' is constructed for a label with
no matching policy is in almost all cases a configuration problem.
A diagnostic message eases pin-pointing such mistaks. By adding the
message to the 'Session_policy', servers don't need to manually handle
the exception to provide diagnostic information. This simplifies the
server code in many components.
In less interactive mode, the run script doesn't give up on missing test
archives but instead removes the corresponding tests and marks them "missing".
This mode avoids total failure of a platform in automated test infrastructures
when only a few archives are missing.
Fixes#3120
After a certain number of tests, presumably some resource in core is exceeded
and loading the successive test fails. This quickfix looks out for the
characteristic Core error and then reboots to avoid that all successive tests
are marked as failed.
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.
Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.
Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.
Issue #3101
This patch improves the appearance of the leitzentrale by eliminating
the (hardly visible) decorations from the GUI and graph views, and by
animating the motion of the graph position. The latter is meant to
remove the stuttering effect when the graph's size changes (and
re-centered).
This patch improves the consistency of the hover handling after
finishing a drag operation. Normally, the window manager hides pointer
updates while the user is performing a drag operation with the mouse
from the decorator. However, in the special case where a drag operation
results in a window-layout change, the decorator's hover model may be
affected. Hence, the window manager must supply the current pointer
position when leaving the drag state.
Issue #3097
This patch supplements the dragging state of window controls to the
window layout so that decorators become able to visually reflect this
state, i.e., pressing the title bar while moving a window.
Issue #3097
This commit adds the optional 'motion=<number>' attribute to the
decorator's <policy> nodes. The default value is 0. If a value higher
than 0 is specified, window-geometry changes are applied as an animation
where the <number> denotes the number of animation steps.
Issue #3096
This patch adds the boolean policy attribute "decoration", which
controls whether window decorations are presented or not. It is enabled
by default. By setting the attribute to "no", matching windows appear
without any border, which is desireable for Sculpt's component graph.
Issue #3096
This patch improves the window decorators in the following respects:
* Strict warnings are enabled now.
* The use of the 'List_model' makes the application of window-
layout changes more robust. This is particularly the case for
the restacking of windows.
* Display-mode changes are now supported by both decorators.
Issue #3094
Until now, decorators used to rely only on the TO_FRONT command for
propagating the window stacking to nitpicker. However, as the additional
use of the TO_BACK command allows for a more robust procedure, this
patch enhances the wm to handle both view stacking commands.
Issue #3094
Adds an config attribute to the Depot Autopilot component:
:<config repeat>:
Can be one of
"false" - process the given test list only once,
"until_forever" - endlessly repeat processing the given test list,
"until_failed" - repeat processing the given test list until it fails.
Adds an environment variable to the Depot Autopilot Run script:
:TEST_REPEAT:
Same as the <config repeat> attribute of the Depot Autopilot.
This is useful when having to debug very sporadic errors during one test
or a series of tests.
This ensures that the depot_autopilot.run script, when exiting, always prints
a result overview of the so far available test results, except the Depot
Autopilot component has managed to print the result overview up to this point.
Unequal numbers of double quotes let the XML parser of init fail,
therefore replace all double quotes when transfering previous
results after a reboot.
Ref #3027
The number of tests to run is the number of test package-archives minus the
the those that are skipped for the given platform. The number is printed
directly after checking if the given platform is supported by the run script.
It helps the surrounding test infrastructure to ensure that, for instance, a
result graph always reflects the same total number of tests, even though there
is a sporadic problem with booting the platform.
The test for python requires x86 to be built. Therefore, there is no test
binary available when trying to execute that test on ARM with depot_autopilot.
This patch constraints the window size of the generated layout to the
minimum of the client's real window size and the wanted window size
(both may differ when resizing or maximizing windows).
This patch improves the handing of new appearing windows for which only
a wildcard assignment - but no exact assignment - rule exists. In the
prior version, an interactively raised window would stay in front of
such a window, which is unintuitive. The new version applies the
to-front mechanism to unknown new windows. For known new windows (with
an exact assignment rule) their original stacking position is preserved.
This patch solves an off-by-one problem in the window-size calculation,
which resulted in sporadic artificial resize requests. In Sculpt, this
glitch caused flickering artifacts in VirtualBox windows caused by
superfluous guest desktop-resize handling.
Furthermore, the patch introduces the dropping of resize requests with
unchanged content.
The commented-out <start> nodes are prone to become inconsistent with
the launchers. Hence, this patch removes them. Start nodes should better
be added by the '+' menu, at least initially.
Furthermore, the patch directs requests for the vfs.lib.so ROM to core's
ROM service to reduce the impact of low-level ABI changes (i.e., the
packet-stream layout) on existing vfs/libc-based packages.
The recall file system is a place where components can remember state.
E.g., to allow the window layouter to recall the window layout of the
previous session.
In a corner case, the toggling of the popup menu entered a state
where the menu could not be opened anymore by the user. Specifically
the following input sequence triggered this problem.
1. The user opens the menu
2. The user clicks on the menu and holds the button
3. While holding the button, the user moves the pointer to the
outside of the popup (e.g., to the '+' button)
4. The user releases the button.
In this situation, the popup is closed but the hover information for the
popup contains still the original clicked-on item. Hence, all subsequent
clicks on the '+' appear as both a click on the '+' (opening the popup)
and a click on the "hovered" popup entry (closing the popup).
The patch explicitely clears the popup's hover information when closing
the popup.
The pthread API is considered a standard feature of libc so better to
simply merge it with the libc. Pthreads are in fact already a part of
the libc in the form of weak symbols. This merger is also a prerequisite
for better integrating pthreads with the libc I/O task.
Fix#3054
Print a line like "succeeded: 35 failed: 11 skipped: 2" below the list of test
results. Adds further attributes to <previous-results> to communicate also the
previous statistics.
This commit moves the window layouter and window decorator into
dedicated packages that can now be combined with the "wm" server at
runtime and restarted/reconfigured/swapped-out independently.
To use the window manager, one must start the 'wm', 'window_layouter',
and one of the 'motif_decorator' or 'themed_decorator' subsystems.
Fixes#3024
When doing the libc_getenv test on autopilot+foc+x86 and one of the
subsequent tests crashes the system so it gets rebooted by the run
script, the system doesn't come up again. It gets stuck after core
initialization.
Issue #3027
This patch improves the detection of new appearing top-most windows.
Such a window should prompt the decorator to bring the corresponding
nitpicker view(s) to the front of the view stack. The original
implementation relied on hints provided by the layouter (the 'topped'
attribute). With the patch, the decorator tracks the top-most window by
itself, which improves the robustness.
As a second improvement, the patch defers the destruction of windows to
the point when all other window operations are completed. This hides
intermediate states when replacing one window by another in one step,
which is typical for console-like scenarios. Hence, this patch should
eliminate flickering artifacts when switching from one virtual console
to another.
Issue #3031
This commit replaces the former floating_window_layouter with a new
window_layouter component that supports the subdivision of screen space
into columns and rows, the concept of layers, and the principle ability
to store window layout information across reboots. The latter is
accomplished by reflecting the component's internal state as a 'rules'
report to the outside.
Fixes#3031
This component allows access to Terminal sessions via interactive SSH
sessions. Please read _repos/gems/src/server/ssh_terminal/README_ for

Fixes#3014.
The new 'conditional' method simplifies the typical use case for
'Constructible' objects where the constructed/destructed state depends
on a configuration parameter. The method alleviates the need to
re-implement the logic again and again.
The patch also removes the 'Reconstructible' constructor arguments
because they are unused.
Fixes#3006
On some machines, both the AHCI and NVMe drivers are started within the
[drivers -> dynamic] subsystem. This ultimately exhausted the RAM quota
of this subsystem.
Issue #2987
This patch introduces the distinction of the manually managed
config/deploy from the managed config/managed/deploy. The latter
incorporates interactive changes of the system by the user. There are
two user interactions supported.
First, by clicking on the '+' button at the top-left of the runtime
view, the user can select a component to launch. All launchers at
config/launcher/ are listed in the popup menu. Each launcher can be
lauched only once. While running, is not available in the popup
menu.
Second, when selecting a node that corresponds to a start node in
config/deploy or that was interactively launched, the detailed view
shows a 'remove' button, which can be used to exclude the component
from the deployment.
The result of the interactive manipulation is always available at
config/managed/deploy. Hence, the current situation can be made
persistent by using it as config/deploy.
Fixes#2986
This patch unifies the handling of on-demand resource upgrades among
ram_fs and depot_rom, and applies the new pattern to the runtime view.
This way, runtime view becomes able to accommodate more complex
scenarios.
This patch enables the user to click on a component in the runtime view
to reveal more information such as the used/assigned RAM/caps and
secondary dependencies.
This patch adds a graph of the current runtime state to the
leitzentrale. The topology of the graph depends on the first routing
rule of each component. For this reason, the patch re-orders routing
policies to make the most important route the first in the list.
The user can switch between the runtime view and the inspect window
by clicking on the corresponding menu dialogs. E.g., a click on the
storage dialog reveals the inspect window.
The PS/2 driver retries to get mouse-reset results for 700 ms, sleeping
after each attempt for 10 ms. So, the driver needs a Timer session now.
Fixes#2713
The most important route of each launcher is at the top of routes and
will be used to layout the graph topology of the runtime view.
By caching the state reports generated by the runtime init, the sculpt
manager becomes able to quickly check for the presence of components. So
we can apply routing-dependency checks not only prior starting
components but also while components are running.
Fixes#2938Fixes#2912
This patch addresses two problems: By guarding the buffer allocation in
a nested class, an exception in the body of the 'File_content'
constructor reverts the allocation. Second, if the file has no content
no allocation should be performed. The previous version wrongly passed
a size of zero to the allocator in this case.
The 'Report' route was missing. The commit also removes superfluous
routing rules for IO_PORT, IRQ, and IO_MEM that are captured by the
subsequenting wildcard anyway.
Issue #2909
The COW plugin provided only partial copy-on-write semantics and had
problems detecting recursive requests. Conversely, the import plugin has
much simpler behavior that is easy to test because it mirrors that of
the ram_fs server.
Ref #2745
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.
