By default, Vim renames a written file to a backup file suffixed with
"~" before writing the current buffer to a new file. Consequently, there
exists an intermediate state when no file exists. Should a client watch
such a file to obtain dynamic configuration info, it observes the empty
state.
Some components have builtin heuristics for such a situation. In
particular, the window layouter falls back to a predefined default
'rules' if no rules are provided as a file. So when interactively
editing window-layouter rules using Vim, it can happen that the manually
maintained rules get overwritten by the default rules.
By setting 'set nowritebackup', we can sidestep this issue by preventing
Vim from producing the bad intermediate state.
Introduce the managing_system privilege for components like the
platform_driver to allow it to call system management functionality
that is reserved by kernel or special firmware, e.g., ARM Trusted Firmware.
The former RAM resource configuration attribute `constrain_phys`,
which enabled to constrain the region of physical RAM to be used,
gets replaced by the new, broader managing_system configuration
attribute of a `start` node. It gets enforced by the sandbox library.
Ref #3816
The sculpt manager used to defer the initialization of the GUI until
nitpicker's first display report became ready. This way, Sculpt was able
to run headlessly even if the framebuffer driver failed to start up.
Thanks to #3827, nitpicker no longer depends on a working framebuffer
driver. So the sculpt manager is safe to rely on nitpicker in any case,
simplifying the code.
Issue #3827
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 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 replaces the use of the "Framebuffer" session interface by
the new "Capture" session interface in all framebuffer drivers. Thanks
to this change, those drivers have become mere clients of the nitpicker
GUI server now, and are no longer critical for the liveliness of the GUI
server.
The patch touches the following areas:
- The actual driver components. The new versions of all drivers have
been tested on the respective hardware. Generally, the drivers
have become simpler.
- The drivers_interactive packages for various boards. The drivers
subsystem no longer provides a "Framebuffer" service but needs a
valid route to the "Capture" service provided by nitpicker.
- The driver manager of Sculpt OS.
- This patch changes the role of the test-framebuffer component from a
framebuffer client to a capture server so that drivers (capture clients)
can be directly connected to the test component without the nitpicker
server.
- Framebuffer driver no longer support the unbuffered mode.
- The fb_bench.run script is no longer very meaningful because it
interplays solely with nitpicker, not with the driver directly.
- All run scripts for graphical scenarios and the related depot
archives got adapted to the change.
Fixes#3813
Until now, Genode's framebuffer session interface was based on the
RGB565 pixel format. This patch changes the pixel format to 32-bit
XRGB where the X part is ignored. It adapts all graphical applications
and device drivers accordingly.
The patch also adjusts the users of the drivers_interactive packages,
assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is
sufficient for covering high resolutions at 32 bits per pixel and to
accommodate multi-component USB HID input stacks.
Fixes#3784
This commit fixes the 'Out_of_caps' handling. The previous version
mistakenly upgraded the RAM instead the caps as response. The problem
could be triggered by the 'decorator_stress.run' script.
If a "cat" tool as simple as the removed one is needed, it should be
implemented with Goa, only depend on libc/posix (*not* base), and be
named "simple_cat". Up to today, the misleading naming of the removed
tool, tricked me into believing "test-pipe" tests POSIX pipes, which it
did not!
The 'WHITESPACE' case of the _calc_len method wrongly accessed the
character before checking upper bound of the token. The problem is fixed
by switching the order of both conditions.
Fixes#3756
This patch removes old 'Allocator_guard' utility and replaces its use
with the modern 'Constrained_ram_allocator'.
The adjustment of core in this respect has the side effect of a more
accurate capability accounting in core's CPU, TRACE, and RM services.
In particular, the dataspace capabilities needed for core-internal
allocations via the 'Sliced_heap' are accounted to the client now.
The same goes for nitpicker and nic_dump as other former users of the
allocator guard. Hence, the patch also touches code at the client and
server sides related to these services.
The only remaining user of the 'Allocator_guard' is the Intel GPU
driver. As the adaptation of this component would be too invasive
without testing, this patch leaves this component unchanged by keeping a
copy of the 'allocator_guard.h' locally at the component.
Fixes#3750
- don't use 'qemu -serial mon:stdio' anymore as it no longer works as
expected
- use "bash -l" with [terminal] to read user's profile configuration,
e.g., PATH settings
- added missing boot modules and cap quotas
This patch increases the default limit of the maximum number of open
file descriptors to the hard limit of the system. This is needed for
complex scenarios, which require more FDs than the default of 1024
at core.

This patch replaces the former Noux instance by a sub init that hosts
the combination of VFS + fs_rom + bash. If bash exits, the whole sub
init exits, which implicitly tears down the terminal session used by the
sub init. The latter is expected by the test sequence.

This patch increases the Sculpt version to avoid the risk of binary
compatibility clashes with index files published for the just-released
Sculpt 20.02 version.

This test covers the situation where depot_query evaluates depot content
that is incompletely extracted. In particular, if the 'archives' file
already exists but has a size of zero, depot_query would produce a
page fault. This situation can be manually provoked by deliberately
creating a zero-sized archives file for any otherwise correct pkg.
This patch also fixes the success indicator of the test. It wrongly
matched an early line of the log output.
Issue #3557
* The log history of a test is stored as a whole for the lifetime of the test.
* Matching of the log history against log patterns is done correctly now
(previously, a pattern like "AAB" on an input like "AAAB" wouldn't have
triggered).
* Use memcmp, memcpy, memmove instead of the former character-wise operations.
* Sanitizing of log input and log patterns now works more generic through the
new Filter class for all replacements/removals.
* Sanitizing is done as soon as a string is available and remains for the
lifetime of the test.
* Sanitizing doesn't interfer with the matching algorithm.
* Decomposing into small clearly named functions.

Nowadays, we use standard command-line tools like vim to edit init
configurations dynamically, which alleviates the need for a custom CLI.
The CLI-monitor component was too limited for use cases like Sculpt
anyway.
The patch also removes the ancient (and untested for long time)
terminal_mux.run script, which used to be the only remaining user of the
CLI monitor.

There are still nightly tests like test-tcp_bulk_lxip on sel4 x86_64 qemu
that manage to hit the test timeout of the run script although the test was
successful. So, raise the extra time added by the run script to 30 seconds.
Ref #3411
Some platforms (sel4 imx6/imx7) cannot manage to execute all tests in a single
boot. Thus, we re-boot them periodically after a given maximum number of tests
to avoid that arbitrary tests always fail due to the long uptime and not due to
the tests themselves.
If the maximum number of tests is set to 0, no limit is applied.
Fixes#3411
The terminal now got a configurable palette for 16 colors (8 normal, 8

</palette>
</config>
Note, the old (undocumented) <color index="..." bg="..."> configuration
scheme is no longer supported.
Also, this commit adds a pleasing default palette that ensures
readability of ViM's standard hightlighting.
Fixes#3406
It might happen, in CPU intensive tests (like TCP bulk lxip), or when
printing debugging output after a failed test (as done currently on

be necessary only in rare cases anyway.

Issue #3222
Issue #3193
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
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

version.

The zynq nic_drv also depends on hw, we therefore adapted the folder

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

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.
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).
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.
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.
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.

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.

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

report to the outside.

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 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 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.

The 'Report' route was missing. The commit also removes superfluous
routing rules for IO_PORT, IRQ, and IO_MEM that are captured by the

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

This commit is a follow-up to "nit_fb: allow screen-relative
initial_width/height". With it, the nit_fb window created via the

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
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.
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.
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.
The state report reflects the progress of downloading, verifying, and
extracting archives. For the download step, it includes the progress
as reported by fetchurl.
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

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.
