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.
This patch makes init robust against invalid routing rules that lack a
name attribute in the '<service>' node. This situation may occur when
interactively editing routes in Sculpt.
Return a value in the same width as provided by the caller of sysctl for
PHYSMEM and USERMEM. This is to ensure that if a caller provides a
64-bit integer, a 64-bit value will be returned for 32-bit machines.
issue #3060
Some application code is dereferencing the pointer returned by
'packet_content' at packet streams without checking that it is valid.
Throw an exception rather than return a null pointer, except for
zero-length packets, which have somewhat implicit invalid content and
that we believe to be properly handled in all current cases.
The client-side of a packet stream cannot take corrective action if the
server-side is sending packets with invalid content, but the servers
that provide packet streams should catch this exception to detect
misbehaving clients.

This enables Qt5 applications to set a Genode label via 'setWindowTitle'
from within Qt5 applications, and thus, making them identifiable to
other Genode components, like a layout manager.

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.
Change the root of a session request into an explicit path and apply the
label-to-path conversion using the "path_prefix" policy attribute. This
is in addition to only applying a root change with a "path" attribute.
Ref #3031Fix#3056
The bulk buffer is now 64Byte-aligned so that the allocated
packets get aligned likewise (assumed the packet allocator uses an
appropriately aligned block size). This ensures that each packet
starts at a new cache line on common platforms.
Issue #3053
Move the libc-i386, libc-amd64, and libc-arm include directories into
the standard "include/spec" directory. This allows the platform specific
headers in the libc API package to be detected in a generic manner.
Ref #3051
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
