This patch changes the 'Allocator' interface to the use of 'Attempt'
return values instead of using exceptions for propagating errors.
To largely uphold compatibility with components using the original
exception-based interface - in particluar use cases where an 'Allocator'
is passed to the 'new' operator - the traditional 'alloc' is still
supported. But it existes merely as a wrapper around the new
'try_alloc'.
Issue #4324
When building the code with clang the following warning message is
prodiced:
"explicit instantiation of 'Scout::Browser_window' must occur in namespace 'Scout'
template class Browser_window<Genode::Pixel_rgb888>"
This happens for several different types. This patch fixes the problem
by instantiating all those templates using their explicit full name.
Issue #3985
The Scout::Spacer constructor requires two arguments. The initialization
of the type in Launchpad_window declaration does not specify them. The
variable is however initialized a second time in class constructor. This is
most likely why GCC accepts this code. Clang on the other hand
complains about it.
Fix this by properly initializing both _spacer and _docview only once at
declaration time.
Issue #3985
This commit restores the diag feature for selecting diagnostic output of
services provided by core. This feature became unavailable with commit
"base: remove dependency from deprecated APIs", which hard-wired the
diag flag for core services to false.
To control this feature, three possible policies can be expressed in a
routing target of init's configuration:
* Forcing silence by specifying 'diag="no"'
* Enabling diagnostics by specifying 'diag="yes"'
* Forwarding the preference of the client by omitting the 'diag'
attribute
Fixes#3962
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
- Since Genode::strncpy is not 100% compatible with the POSIX
strncpy function, better use a distinct name.
- Remove bogus return value from the function, easing the potential
enforcement of mandatory return-value checks later.
Fixes#3752
