[E-devel] Lua leaking resources (timers, idlers, animators...)

[Gustavo Sverzut Barbieri]

Hi all,

I don't know Lua (yet), but if someone can look at
edje_lua.c/edje_file.c, the deletion of an Edje object does not delete
associated resources such as timers, idlers, animators.

I'll dig into this, but any help is appreciated.

See attached files for working example of the problem. Run and it will
crash as timer will tick but referring object is gone.   Code is
courtesy of Rafael Fonseca, who spotted the problem.

BR,
