commit 7d9ac365039a23b704738b63a54bbbae6e9f6f3a
Author: Stephan Bergmann <sberg...@redhat.com>

Replace salhelper::SingletonRef with rtl::Static
When destroying the static vcl::CommandInfoProvider aProvider from
vcl::CommandInfoProvider::Instance
(vcl/source/helper/commandinfoprovider.cxx)
during exit, it releases its mxCachedGlobalAcceleratorConfiguration
reference on
GlobalAcceleratorConfiguration
(framework/source/accelerators/globalacceleratorconfiguration.cxx), which
may
get destroyed, whose base class framework::XCUBasedAcceleratorConfiguration
(framework/source/inc/accelerators/acceleratorconfiguration.hxx) has a
salhelper::SingletonRef<framework::KeyMapping> member, whose destructor
(include/salhelper/singletonref.hxx) uses
salhelper::SingletonRef<framework::KeyMapping>::SingletonLockInit::operator
()'s
static osl::Mutex aInstance.
If, during construction, the instantiation of
salhelper::SingletonRef<framework::KeyMapping>::SingletonLockInit::operator
()'s
static osl::Mutex aInstance finishes before the instantiation of
vcl::CommandInfoProvider::Instance's static vcl::CommandInfoProvider
aProvider,
the corresponding atexit cleanup actions will be recorded in the right
order,
causing the above chain of calls to find the static Mutex still alive when
used
from within the static CommandInfoProvider's destruction.
However, vcl::CommandInfoProvider's mxCachedGlobalAcceleratorConfiguration
is
only set to css::ui::GlobalAcceleratorConfiguration::create in
vcl::CommandInfoProvider::GetGlobalAcceleratorConfiguration, so the
instantiation of the static Mutex instance can finish after the
instantiation of
the static CommandInfoProvider instance, recording the atexit cleanup
actions in
the wrong order, causing the static Mutex to be used after destruction.
This occasionally caused PythonTest_sfx2_python to hang during exit for me
on
Linux, where trying to lock a destroyed pthread mutex can apparently
deadlock.
rtl::Static does away with the need to do anything in the destructor, at the
expense of always keeping the instance alive until exit (and not being able
to
recreate an already destroyed instance during exit, but code that would
require
that behavior would probably already be broken to begin with), so the order
of
creation of the CommandInfoProvider and GlobalAcceleratorConfiguration
instances
becomes less of a concern.
