Test WADs for wadptr compression. Use the run_tests.sh script to run tests. Included here are:

  • The 6fiffy* series, levels by George Fiffy (King REoL) who is notorious for his "extreme detail" levels that contain a large number of linedefs and sidedefs. 6fiffy6.wad is a Hexen format level, which checks that we handle such WADs appropriately.
  • Eternal Doom, which is similarly notorious for having very large levels.
  • crymap02.wad is MAP02 from Cryogenics, a large level that contains an empty BLOCKMAP lump.
  • evimap32.wad is MAP32 from Eviternity, an exceedingly large level.
  • btsx2m20.wad is MAP20 from BTSX E2, which is a very large level close to the vanilla BLOCKMAP limit and that has been built with ZokumBSP to make it fit within the limit. So we check that we can at least process that BLOCKMAP without making it any larger. The WAD has a single redundant byte at the end so that wadptr will successfully reduce its size.
  • btsxcred.wad is the CREDIT screen graphic from btsx_e1a.wad, which has its columns unnecessarily spread into two posts, and checks that the code to combine posts works as intended.
  • 64c30n9.wad is a Doom 64-format WAD. A single zero byte has been appended to the end of the WAD so that the tests successfully reduce the file size.
  • gotcha3.wad contains a graphic lump (PLATFORM) that is corrupted; we print an error message when such lumps are encountered but otherwise proceed without changing their contents.

Mini / unit test WADs:

  • samelump.wad contains two lumps with identical contents; this confirms that the WAD merging code works as intended.
  • samecol.wad has a single graphic containing two identical columns, to confirm those will be combined.
  • suffix.wad has a single graphic containing two columns that are different, but one column is a suffix of the other.
  • packable.wad contains a minimal level with four identical sidedefs that can be packed, but the blockmap is too small to be stackable.
  • hxpackable.wad, same thing but in Hexen format.
  • stackable.wad contains a minimal level with no identical sidedefs (cannot be packed), but is large enough that the blockmap can be stacked.
  • mixed.wad contains both a Doom format level and a Hexen format level, to check that we correctly handle mixed-format WADs.
  • bad_sdi.wad is a copy of packable.wad containing a bad sidedef reference on one of its linedefs, to confirm that such WADs can still be processed successfully (albeit with an error message).
