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.
With the change of nitpicker to the event session interface, the
formerly periodic hovering updates moved to the - now sporadic - input
processing. This has the unfortunate side effect that hovering changes
caused by non-user-input, in particular view-stack changes issued by the
GUI clients that change the view under the current pointer position,
would no longer be reported immediately but only after receiving the
next incoming input event.
This patch reworks the hover handling such that potential hovering
changes due to view-stack operations are evaluated immediately by
those operations, covering the update of the hover report and the
generation of artificial enter/motion events.
Issue #3812
This patch solves a corner case where one long-active job (e.g.,
read-ready request) stays at the beginning of the '_active_jobs' queue
without an ack. In this case, the '_try_acknowledge_jobs' method would
wrongly stop processing the subsequent acknowledgements. In practice,
this can lead to a delayed sending of acknowledgements until new I/O or
client requests occur. In particular, Vim in Sculpt's inspect window
sometimes did not immediately respond to key presses during tab
completion. Here, the read-ready request of the terminal prevented the
acknowledgement for read of directory entry from being delivered until
the next key was pressed.
Fixes#3873
The quota for the argument buffer is already accounted by using the
Attached_ram_dataspace _argument_buffer, which uses the Constraint_ram_allocator
_ram, which uses the Ram_quota_guard from the Session_object. Running on
Sculpt with more than 1000 Subject_info objects/trace IDs the memory
waste become noticeable.
Follow-up commit to fix the old usb_drv. Under rpi one and the
same irq can be requested several times. Therefore, we've to track
the Irq_connection objects.

It seems Qemu 5.0.0 no longer supports gic_version parameter.
Apparently this only worked due to some compat feature that
was dropped in Qemu 5.0.0. The replacement which works on both
old and new Qemu versions is gic-version.
Fixes#3823
The Lx_kit::Irq abstraction of DDE Linux was always using the very first
interrupt of a Platform::Device stored in it. Instead of handing over the
platform device it is much more flexible and sane to hand over the actual
interrupt capability.
Ref #3865
By now, the enumeration of peripheral interrupts on Raspberry Pi 1 was
different in between base-hw kernel and Fiasco.OC. Therefore, hacks were
needed in every driver to request the correct interrupt number dependent
on the kernel. Before reproducing the same in the platform driver for rpi,
we can more easily use the same enumeration with base-hw.

This is a temporary workaround to not harm drivers, which aren't
converted yet to request all device resources including power and
clocks from this new platform driver.

To access the ARM Trusted Firmware from the platform driver
fill the new `managing_system` call of the PD session with life resp.
do a SMC call on behalf of the client.
Fix#3816
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
Normally CLOCK_REALTIME is used. However libraries, like glib, want to
use CLOCK_MONOTONIC. To make those users happy add setting the clock.
Note, the pthread_cond implementation uses the POSIX semaphore API
internally that does not have means to set the clock. For this reason,
the private 'sem_set_clock' function is introduced.
Fixes#3846.
When the 'raw' attribute is set to 'yes' the terminal VFS plugin will
ignore control characters. This in necessary for terminal connections
that transport data that contain such characters as part of message.
Fixes#3860.
The driver wrongly rejected a block request for the very last block of
the device, which prevented part_block from successfully parsing the
partition table (when attempting to access the GPT backup).
Fixes#3861
With this patch, sculpt uses init's heartbeat-monitoring mechanism to
detect the failure of part_block instances during storage disovery.
If part_block gets stuck, the device is released and can thereby
be accessed at the whole-device level.
