Looks like SWIG silently ignores default arguments specified via
aggregate initialization. This is rather unfortunate, especially
if the argument types are complex.
Replace custom Deleter classes with std::default_delete<>, declared
as friend so it can invoke the private destructor. Inexplicably,
std::shared_ptr<> does not use default_delete<> by default, so it
is still necessary to explicitly specify the deleter when creating
shared_ptr instances.
With this, unique_ptr and shared_ptr instances now use the same
default delete mechanism.
Make use of std::unique_ptr<> to manage the lifetime of members
or container elements, so that manual invocations of delete can
be avoided. This also provides for exception safety.
Since std::unique_ptr<> is only movable but not copyable, adapt
the code to avoid copies and assignments of these pointers.
Reduce needless over-generalization. There is no design need
for the ParentOwned and UserOwned classes to contain the C base
struct pointer. Instead, just make the _structure pointer a
private member of each class that needs one.
Declare accessor methods that return value members const. For now,
skip all cases where constness would have to be applied transitively
to shared objects.
Context::package_version() and Context::lib_version() do not access
context state and should be static. However, leave the logging
related methods alone for now, as making them static would entail
making the callback data a global static, since the C API lacks
destroy notification callbacks.
If one of these functions does throw an exception, std::terminate()
will be called. Without this, the behavior is undefined since the C
stack is not prepared to deal with exceptions.
Make use of std::move() to transfer arguments passed in by value.
Take complex container arguments by const reference, as passing
those by value is rather unorthodox even for C++11 style code.
Completely remove the old session save code that has been
superseded by the srzip output module. Also refactor a bit,
plug a number of leaks and tighten the error checking.
The confusingly named sr_log_logdomain_set() simply set a global
string prefixed to the log message by the default log callback.
This is pretty much useless, misleadingly named, and not used by
either sigrok-cli or PulseView.
This fixes a build problem due to the reduced include search paths
introduced by my recent changes. Also fix a couple of other
includes to use angle brackets.
As per upstream docs "#include <glibmm.h>" is the correct usage,
the "glibmm-2.4" directory is handled correctly via pkg-config:
$ pkg-config --cflags glibmm-2.4
-I/usr/include/glibmm-2.4 [...]
