The implementations of snprintf and vsnprintf are not needed for the
loading of png images by the demo applications. So we can avoid the
dependency from the format library hosted in the libports repository.
Issue #2064
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
