Dr Stephen L S Webb commented on LOGCXX-532:
--------------------------------------------
I suggest LoggerRepository (or Hierarchy) hold a collection of weak pointers
(say myLoggers) to the Loggers.
Logger can hold a raw pointer to the LoggerRepository. The LoggerRepository
destructor should then do
{code:java}
for (auto& item : this->myLoggers)
{
if (auto pLogger = item.lock())
pLogger->resetRepository();
}{code}

> URL: https://issues.apache.org/jira/browse/LOGCXX-532
> Project: Log4cxx
> Issue Type: Improvement
> Reporter: Robert Middleton
> Assignee: Robert Middleton
> Priority: Minor
>
> As seen in LOGCXX-430 and LOGCXX-322, making sure that when an application
> terminates earlier than expected we don't crash is rather hard to do.
> I came across this solution when researching this problem:
> https://stackoverflow.com/a/470545/624483
> My thought is that we create something like a log4cxx::Globals class, which
> contains a smart pointer to everything that must be kept alive before the
> library can safely be unloaded. In each thread, you would do something like:
> {{GlobalsPtr globals = log4cxx::globals;}}
> thus ensuring that the destructor can't run before all of the threads are
> stopped. This would be up to the user of the library.
