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!
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.

This depot package is the runtime for rtc_drv and system_rtc server with
coordinated update of system and hardware RTC via reports. It replaces
drivers_rtc which was never freestanding drivers package and, therefore,
has to be accompanied with a running platform_drv etc.
Fixes#3680
The new text_area component is able to view and edit files.
Internally, it employs a menu_view for the graphics output.
Only basic notepad-like text-editing functions are supported.
At the current time, it is solely meant as a companion of the Sculpt
manager.
Issue #3650
This commit adds dynamic switching in between different defined
screens via keyboard shortcuts, or by editing the rules file.
In the window_layouter package it defines per default ten screens,
reachable by pressing the screen key along with numbers 0-9.
Fix#3646
Add a new plugin for creating pipes between pairs of VFS handles. It is
intended to replace the libc_pipe plugin, one of the last remaining libc
plugins.
In contrast to the libc_pipe plugin, this plugin defers cross-handle
notification until I/O signal handling rather than block and unblock
readers using a semaphore. This is a performance regression in the case
of multiple threads blocking on a pipe, but shall be an intermediate
mechanism pending renovations within the libc VFS and threading layers.
As a side effect, threads blocked on a pipe might not be resumed until
the main thread suspends and dispatches I/O signals.
The "test-libc_pipe" test has been adjusted to use the VFS pipe plugin
and tests both local pipes and pipes hosted remotely in the VFS server.

interface changes) by Norman Feske.

This adds complete character-generator configurations for English (US),
German (Germany and Switzerland), and French (France and Switzerland).
The configs are manually amended and stripped-down versions of
xkb2ifcfg generated configs.
Issue #3483
This commit implements the ssh exec channel request. It also handles
some shortcommings on the interactive channel like exit and concurrent
session establishments.
Pipes into the channel do not work yet. E.g.:
echo foobar | ssh noux@localhost -p 5555 "cat > /rw/test.txt"
The issue described with FIXME in Ssh::Server::incoming_connection()
could not be reproduced and might have been fixed with the improved
file descriptor handling.
Fixes#3401
The labels of clipboard ROM and clipboard report sessions of WM clients
must be consistent with the client's nitpicker label. Hence, we must
route those sessions through the window manager, analogously to the
approach taken for shape reports in #3165.
Issue #3437
This patch introduces two caches to the depot-query tool.
- A stat cache remembers the results of 'Directory::file_exists'
calls.
- The 'Cached_rom_query' caches the result of scanning the depot
for a given ROM module and pkg path. To elminates the need to
parse 'archive' files of pkgs referenced from other pkgs or
for the repeated instantation of the same pkg.
Both caches are bypassed whenever referring to the 'local' depot user.
Fixes#3427
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
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.

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
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
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.
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
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
more detailed information.
Fixes#3014.
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
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 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.
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 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.
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
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
