load content keeps 2 files open when playing a networked rom

Is there an existing issue for this?

• This is a bug in RetroArch frontend
• I have searched the existing issues

Description

This is a bug that makes using a network filesystem like webdav over android and rsaf much much slower.

Apparently either because of the server, or rsaf or just the nature of open() over a network, keeping two files open at the same time destroys performance

I know this because rsaf says how many files it has open. If I load a game from a playlist, its "1" (or one at a time for cue/bins I suppose) for "load content" of a single file it's "2" and performance is much worse

I think what's happening is that the filebrowser never closes the directory it reads even as the game starts so the game plays in the load content case (which uses the filebrowser) with two files open.

Expected behavior

Rsaf only reporting 1 file open just like it does when a game is loaded from playlists/when you stop using the filebrowser resources used like open files get freed.

Steps to reproduce the bug

Pretty difficult. Have a webdav server in the same WiFi network as a android phone, install rsaf and configure a webdav entry there, load up retroarch and load that directory as a authorized SAF uri, then scan 1 game there in a playlist and compare the performance of loading from load content or the playlist and notice rsaf saying playlist has 1 file open and load content has 2.

Relevant log output

No file or test is named. Start by comparing the playlist and Load Content paths on Android with the described WebDAV/SAF setup, then trace which resources remain open while playback begins. Done means both paths release the filebrowser resources and report one open file during playback.
