Re: memory management with glibmm & giomm

[nico <nico yojik eu>]

Hello,

One week ago, I sent an email about a leak of memory of a program that 
list files of a directory (using giomm).
My program was inspired by an official sample code (that we can get 
here: 
http://svn.gnome.org/viewvc/gtkmm-documentation/trunk/examples/book/giomm/directory_list/)

In fact, there is a bug in this sample program:

>  *Glib*::RefPtr<Gio::FileInfo> file_info = enumerator->next_file();
>     *while*(file_info)
>     {
>       *std*::cout << *"file: "* << file_info->get_name() << std::endl;
>       file_info = enumerator->next_file();
>     }
This piece of code create FileInfo objects and never unref them.
The right code would have beeb:
>  Glib::RefPtr<Gio::FileInfo> file_info = enumerator->next_file();
>     while(file_info)
>     {
>       std::cout << "file: " << file_info->get_name() << std::endl;
>       file_info = enumerator->next_file();
>       file_info->unreference();
>     }
Or, an other variant :
> while(Glib::RefPtr<Gio::FileInfo> file_info = enumerator->next_file()) {
>     std::cout << "file: " << file_info->get_name() << std::endl;
>     file_info->unreference();
> }
I'll try to report the bug,
