[Cppcms-users] Destroying all sessions on application exit

[Christian G. <chr...@gm...>]

Hi.

I am using a custom session_storage, which creates a temporary folder
for each user-session at a defined path - e.g. /media/session_storage.


namespace cppcms {
namespace sessions {

    class session_memory_ext_storage_factory;

    class CPPCMS_API session_memory_ext_storage : public session_storage {
    public:
        session_memory_ext_storage(std::string const &base) : base_(base) {}
        virtual ~session_memory_ext_storage() {}

        virtual void save(std::string const &key,time_t to,std::string
const &value);
        virtual bool load(std::string const &key,time_t &to,std::string &value);
        virtual void remove(std::string const &key);
        virtual bool is_blocking();

    private:
        void gc();
        bool removeRecursively(const QString &path);

        typedef std::multimap<time_t,std::string> timeout_type;
        struct _data {
            time_t timeout;
            std::string info;
            std::string path;
            timeout_type::iterator timeout_ptr;
        };
        typedef boost::unordered_map<std::string,_data> map_type;
        map_type map_;
        timeout_type timeout_;
        booster::shared_mutex mutex_;

        std::string base_;

        friend class session_memory_ext_storage_factory;
    };

    class CPPCMS_API session_memory_ext_storage_factory : public
session_storage_factory {
    public:
        session_memory_ext_storage_factory(std::string const &base);
        virtual booster::shared_ptr<session_storage> get();
        virtual bool requires_gc();
        virtual void gc_job();
        virtual ~session_memory_ext_storage_factory();
    private:
        booster::shared_ptr<session_memory_ext_storage> storage_;
    };

} // sessions
} // cppcms


If i kill the cppcms based application some session folders are still
existent. Is there a way to clean-up all sessions on application exit?

thanks
