2015-05-10Add back the Doom PWAD reload hack.Simon Howard
This was removed back in d190b596c566394717324296cbf6b46e67c64f5c; at the time I didn't understand what it was or how it was supposed to be used - it seemed like cruft left over from Doom's development. It is actually a potentially useful feature for level authors when developing their maps. See here: http://doomwiki.org/wiki/Reload_hack The reload hack is a relatively obscure feature of limited usefulness nowadays, but nonetheless a technical curiosity that ought to be preserved in Chocolate Doom. The reimplementation here is a lot cleaner than the original version from the source release: W_Reload() is based on a call to W_AddFile(), we don't reopen the reload file every time we want to read a lump, and we include a check in W_AddFile() that we are not trying to use the hack on more than one PWAD file. This fixes #539.
2014-10-16Fix crash caused by adding a new WAD file.Simon Howard
This fixes #442, a crash caused by adding a new WAD file after a lump has been loaded (and cached) from a previous WAD. This manifested when playing using the Freedoom IWADs and also loading a PWAD at the same time. The Freedoom IWADs have DEHACKED lumps that are loaded from within the IWAD file. The ultimate cause (thanks to Fabian Greffrath for uncovering it) is that lumpinfo is realloc()ed after each new WAD load to store the lumpinfo_t structures from the new WAD. If a lump has been read and cached from a previous WAD file, it may end up having an invalid 'user' pointer that points to somewhere in the old lumpinfo[] array, not the new one. I think this bug was masked because realloc() will often not move data if the previous location can simply be extended. The bug was discovered when loading BTSX as a PWAD, probably because it's a large WAD that contains a lot of lumps, and forced a move during realloc.
2014-05-05Clean up file headers.Simon Howard
This change rewrites and simplifies the copyright headers at the top of all source files: * Remove "Emacs style mode select" line; this line was included in the headers for the originally released source files and appears to be to set the file type for old versions of Emacs. I'm not sure entirely why it was required but I don't think it is any more. * Remove "You should have received a copy of..." text from copyright header. This refers to the old 59 Temple Place address where the FSF headquarters used to be located and is no longer correct. Rather than change to the new address, just remove the paragraph as it is superfluous anyway. This fixes #311. * Remove ---- separator lines so that the file headers are barer and more simplified.
2014-04-19Exit with error on startup if using the wrong IWAD.Simon Howard
Having multiple binaries can cause some confusion - some users try to run chocolate-doom with hexen.wad, thinking it is supported. Add a startup check that makes sure the user is not trying to start the game using the wrong IWAD file for the binary being run. This fixes #382.

2006-09-02Add -nwtmerge option, which behaves the same as NWT's -merge option. What thisSimon Howard
does is load a PWAD, then search through the IWAD sprites list, removing lumps where there are lumps of the same name in the PWAD. The PWAD must then be loaded again with the normal -file option. This is needed to run TiC's Obituary TC: chocolate-doom -nwtmerge obtic2.wad -file obtic1.wad obtic2.wad -deh obtic1.deh Also add W_PrintDirectory debug function, W_AddFile changed to return handle.
