The old inline assembly provided two output operands that were afterwards
combined for a return value. However, the second output operand isn't
necessary when using the "Acquiring a Lock" example-code of the ARM manual
"Barrier Litmus Tests and Cookbook". This saves two logical operations
per acquisition try. Additionally better documentation is now provided.
Fixes#1292
This patch adds the items necessary for building Genode components with
stack protection enabled, but it is not initialized at runtime. They are
provided at the moment as a convenience and do not implement a security
feature.
Fix#3066
This is a safeguard against accidentally taking the 'Ack' interface as a
value instead of a reference.
The 'Payload' interface should also not be copied (and potentially
stored) because it contains a pointer.
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 reworks the 'Session_component::destroy' to cope become
robust against a client-provided invalid view handle. The code did not
consider that 'Handle_registry::has_handle' may throw.
Thanks to Alexander Boettcher for reporting and the initial fix.
Fixes#3232
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.
If a component is being destroyed just before it calls `exit()` at its
parent, the `exit()` call causes an `Ipc_error` exception, which leads to
an `abort()` loop with repeated error messages, because `abort()` calls
`exit()` too. Catching the exception in `Expanding_parent_client::exit()`
avoids this problem.
Fixes#3228
bus or device should be different (not both) when comparing a device to
already present devices. Because of this the second USB device was
marked as existent when the bus matched or the bus did not but the
device number.
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
Without this patch, a version change of an already exited child would not
trigger the restart of the child because the version is evaluated as
late as the child configuration, but only if the child has not exited
yet.
This patch evaluates the version at the earlier stage where the identity
of the child (its name) is checked against the new configuration.
Fixes#3226
The disk image contains an extended partition table now that would
have been parsed incorrectly in the past. While there remove the unused
gpt BLOB (test-part_block_gpt has its own raw archive).
Issue #3223.
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.
* Introduces pending_signal syscall to check for new signals for the
calling thread without blocking
* Implements pending_signal in the base-library specific for hw to use the
new syscall
Fix#3217
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.
