This is a proposed Change for Fedora Linux. This document represents a proposed Change. As part of the Changes process, proposals are publicly announced in order to receive community feedback. This proposal will only be implemented if approved by the Fedora Engineering Steering Committee.
== Summary == This Change proposes to replace SDL 2 with sdl2-compat, which uses SDL 3.
== Owner ==
* Name: [[User:Ngompa| Neal Gompa]] * Email: ngompa13@gmail.com
== Detailed Description == SDL 2 feature development ended some time ago with efforts being focused on SDL 3. However, many older games still use SDL 2 and cannot change to SDL 3. In order to continue to support SDL 2 games in the modern world, let's replace SDL 2 with sdl2-compat, which uses SDL 3. This also has the effect of moving SDL 1.2 games to SDL3 through sdl12-compat running on sdl2-compat.
== Feedback ==
== Benefit to Fedora == Switching SDL 2 powered games to use <code>sdl2-compat</code> ensures that SDL-based applications continue to use the actively developed codebase. This also has the effect of SDL 1.2 powered games that use <code>sdl12-compat</code> to run on SDL3 as well through the fully supported path of <code>sdl12-compat</code> running on <code>sdl2-compat</code> running on SDL3.
== Scope == * Proposal owners: ** Package [https://github.com/libsdl-org/sdl2-compat libsdl2-compat] (native: [https://bugzilla.redhat.com/2316576 RH#2316576], mingw: [https://bugzilla.redhat.com/2330101 RH#2330101]) ** Retire {{package|SDL2}} and {{package|mingw-SDL2}} completely
* Other developers:
* Release engineering: [https://pagure.io/releng/issue/12485 #12485]
* Policies and guidelines: N/A (not needed for this Change)
* Trademark approval: N/A (not needed for this Change)
* Alignment with the Fedora Strategy: N/A
== Upgrade/compatibility impact == The <code>SDL2</code> package would be transparently upgraded to <code>libsdl2-compat</code> package and games using it should just transparently start using SDL 3.0.
== How To Test == The testing steps are simple:
0. Enable the [https://copr.fedorainfracloud.org/coprs/ngompa/SDL2onSDL3/ <code>SDL2onSDL3</code> COPR]: <code>dnf copr enable ngompa/SDL2onSDL3</code>
1. Swap <code>SDL2</code> for <code>sdl2-compat</code>: <code>dnf swap SDL2 sdl2-compat</code>
2. Run something that uses SDL 2 like {{package|supertuxkart}} and see that it works.
3. Run something that uses SDL 1.2 like {{package|icebreaker}} and see that it works.
Issues should be reported upstream for the fastest response: https://github.com/libsdl-org/sdl2-compat/issues
<!-- REQUIRED FOR SYSTEM WIDE CHANGES -->
== User Experience == There shouldn't be a noticeable user impact, other than possibly a smoother experience because applications are using SDL 3.0.
== Dependencies ==
== Contingency Plan ==
* Contingency mechanism: Revert back to shipping SDL2 / mingw-SDL2 packages
* Contingency deadline: Final Freeze
* Blocks release? N/A (not a System Wide Change)
== Documentation ==
N/A (not a System Wide Change)
== Release Notes == Applications that use SDL 2 will now transparently use SDL 3 through the <code>sdl2-compat</code> package. This makes it so applications that historically used SDL 2 now use SDL 3.
