Summary: SDL_DROPFILE Memory Leak
Product: SDL Reporter: Ash <ash>
Component: eventsAssignee: Sam Lantinga <slouken>
Status: ASSIGNED --- QA Contact: Sam Lantinga <slouken>
Severity: minor    
Priority: P2    
Version: HG 2.1   
Hardware: All   
OS: All   

Description Ash 2020-02-13 20:33:58 UTC 
SDL_DROPFILE events are enabled by default. When a user drags and drops one or more files onto a window, dynamic memory is allocated for each file path. This is done via SDL_SendDrop on line 64 of SDL_dropevents.c (SDL version 2.0.10).

This means that every SDL2 application has a possible memory leak if the application never checks for SDL_DROPFILE events in its event loop.

The Wiki says that this existed since version 2.0.0. Because SDL_DROPTEXT uses the same code path since version 2.0.5, it would also be affected.

That's correct. We will address this in the next major version of SDL where we break ABI compatibility.
