Commit: 56bd7adce74d2601d8656decf4cccb27aee4c6e4 Author: Lukas Stockner Date: Wed Dec 8 23:35:47 2021 +0100 Branches: blender-v3.0-release https://developer.blender.org/rB56bd7adce74d2601d8656decf4cccb27aee4c6e4
Fix T93858: Zstd-compressed .blend files from external tools aren't recognized The issue here was that after the seek table check, the underlying file wasn't rewound to the start, so the code that checks for the BLENDER header immediately reaches EOF and fails. Since Blender always writes files with a seek table, this bug isn't triggered by files saved in Blender itself. However, files compressed in external tools generally don't have a seek table. =================================================================== M source/blender/blenlib/intern/filereader_zstd.c =================================================================== diff --git a/source/blender/blenlib/intern/filereader_zstd.c b/source/blender/blenlib/intern/filereader_zstd.c index 55ce32713d9..5a04f5b11f3 100644 --- a/source/blender/blenlib/intern/filereader_zstd.c +++ b/source/blender/blenlib/intern/filereader_zstd.c @@ -331,5 +331,8 @@ FileReader *BLI_filereader_new_zstd(FileReader *base) } zstd->reader.close = zstd_close; + /* Rewind after the seek table check so that zstd_read starts at the file's start. */ + zstd->base->seek(zstd->base, 0, SEEK_SET); + return (FileReader *)zstd; } _______________________________________________ Bf-blender-cvs mailing list [email protected] List details, subscription details or unsubscribe: https://lists.blender.org/mailman/listinfo/bf-blender-cvs
