ChangeLog

	* TODO: see below, and in the "TODO" file. Enjoy!

Mon Dec 22 20:29:16 1997    <bk@gamers.org>

	* CVS logs and other obsolete stuff removed. Anybody
 	  who wants to keep some revision control now has a
 	  clean slate to start with.

Mon Dec 22 19:53:34 1997    <bk@gamers.org>

	
	* i_sound.c: enabled SNDSERV, as SNDINTR for
 	  some reason just gives ghastly results e.g.
	  on E4M2. Frankly, I am at a loss. SNDSERV is
	  now default, until the internal sound driver
	  is a bit more reliable.
	  Note that the current redundancy means that
	  changes like the one below will have to 
	  be propagated manually to the soundserver
	  sources.

	* m_menu.c: the 4th episode is now removed with
	  the original doom.wad. You need to rename the
	  Ultimate DOOM/Special Edition retail IWAD to
	  doomu.wad now, or you won't see the 4th episode
	  in the menu. The compile time SPECIAL define
	  is thus gone.

Mon Dec 22 17:08:33 1997    <bk@gamers.org>

	* v_video.c (V_DrawPatch): another last minute hack.
	  While shareware, retail, commercial, and plutonia
	  (being a full DOOM2 IWAD) seem to work okay now,
	  TNT gives an error on finishing the first mission:
	   "Patch at -35, -5 exceeds LFB".
	  I changed the error abort into a simple return,
	  thus the patch is ignored. The intermission screen
	  seems to come up okay.
	* TODO: check which patch, and whether it is an IWAD
	  problem.

	* i_sound.c: the sound table is hardwired in
	  sounds.h/sounds.c. As our current crude
 	  sound handling simply loads *all* sounds at
	  startup, we are going to miss some with DOOM1
	  WAD files. I could skip them, but decided to
	  load a placeholder instead (dspistol). It might
	  be good to use a distinct default sound for
	  WAD debug purposes. A zero length sound lump
	  would work, but would not be noticeable.
	  Anyway, shareware and retail work now.
	* TODO: implement proper handling for missing
	  lumps, sound and otherwise.
	  Perhaps move sound table into WAD?

	* g_game.c (G_DoPlayDemo): finally removed the
	  annoying "Demo is from a different game version"
	  abort. It now simply declines to playback the
	  demo, and waits for user input on some
	  do_nothing screen.

	* doomdef.h&Cie.: Lesson of the day - do not
	  replace a bunch of booleans with an enum and
	  use the same identifiers. Point in case:
	   "if ( commercial )" will not give an error,
	  and will always be true as long as the enum
	  value is greater than zero.
	  I found that the DOOM2 vs. DOOM differences
	  are everywhere (weapons, monsters, doors).
	  Number of episodes varies from shareware/commercial
	  to registered to retail, while commercial has
 	  a unique set (two of them, counting the german
	  edition) of maps in one episode. Plus, TNT and
	  Plutonia add some TITLE strings to the mixture.
	  
	  Well, Plutonia and TNT are treated as DOOM2 for
	  now, so you will miss the startup message.

	* wi_stuff.h (NUMEPISODES): removed SPECIAL switch.
	  It is no 4 times 9 for wi_stuff.c internal
	  static arrays - doesn't matter.
	* TODO: unified handling with DOOM 2 - dynamic
	  allocation of arrays.

	* i_sound.c (I_UpdateSound): okay, I separated
 	  the mixing, now done synchonously, along with
	  a flag signalling the timer that the mixing buffer
	  has been updated. The handler is now very short,
	  and I tried several intervals down to 50usecs,
	  w/o complaints. Now the man page says:
	   "system timer resolution currently 10ms". Odd.
	  Anyway, while the double shotgun/plasma rapid
	  fire problem seems to be a bit less disturbing
	  at higher refresh, it's still there. I set the
	  interval to 500usec, which is sufficient for
	  avoiding any buffer update misses.
	  Conclusion after just two days of experimentation:
	  yep, sound driver code isn't fun at all.

	  As for the bug - well, Dave Taylor suggested
	  close distance getting into a divide-by-near-zero
	  situation, screwing up the volume. I can't figure
	  why latency of an external sound driver or screen
	  size affect this, but I am running out of ideas.
	
	* i_sound.c: 
	  Some more experimentation with the timer driven
	  sound. It doesn't work well using an intervall
	  of less then 30 msecs - there will be artifacts
	  with say 50 msecs. This is pretty obvious with
 	  a target frame rate of at least 30fps, methinks.
	  Using the REAL/SIGALRM timer with 30msec gets
	  rid of the artifacts, it seems - at the expense
	  of slowing down things on a P133 to a noticeable
	  jerkiness. Bah.

Mon Dec 22 00:36:54 1997    <bk@gamers.org>

	* info.c: and i_video.c and i_sound.c - don't ask
	  me why some Linux header files are different with
	  gcc vs. g++, or what the complaint about the g++
  	  complaint info.c state table is all about:
	  "initializer element for `states[..].action.acp1' 
	   is not constant"
	  Undid some changes, compiled with gcc, playtested,
	  seems okay. Done for today... yesterday.

	* i_net.c (ntohl): okay, htons/htonl, ntohs,ntohl 
	  are back to haunt me. Copied the macros that
	  on my box aren't used for whatever reason directly
	  into the source. Got rid of all other multiple and
	  undefined references. CC=g++ now compiles (still
	  many warnings) and links, but the binary dumps a
	  core after Init PlayLoop. So be it.

Sun Dec 21 12:38:08 1997    <bk@gamers.org>

	* p_enemy.c (P_NewChaseDir): changed tdir to int,
	  removed the LUTs - spurious locks were due to
	  endless loops created by boneheaded predecessor
	  map. Has to be a better way to do enum dirtype_t
	  anyway. Problem seems to be fixed.

	* CC=gcc again, this time loads of #includes to
	  fix "implicit declarations, and one or two
	  unused variables. DOOM now compiles without
	  any -Wall warnings left, as C.

	* Bug: compiled the reworked code with gcc. Within a
	  solid while of testing and blasting away, it
	  locked once. Got a core, which gdb doesn't grok.
	  Bah.

	* TODO: okay, linkage of g++ build modules give loads
	  of errors, because we have many implicits, plus
	  missing #pragma implementation causing multiple
	  definitions. Yet, this is the very first time DOOM
	  was compiled as C++ without a parsing error. So there.
	
	* sounds.c: included doomtype.h and removed yet another
	            enum { false, true } definition.

	* p_saveg.c  (misc): several. 
	* p_mobj.c   (P_SpawnMobj): (actionf_p1)P_MobjThinker
	* p_spec.c   (EV_DoDonut): (action_p1) T_MoveFloor (twice).
	* p_plats.c  (EV_DoPlat): (actionf_p1) T_PlatRaise.
	* p_plats.c  (EV_StopPlat): (actionf_v)NULL.
	* p_plats.c  (P_ActivateInStasis): same
	* p_lights.c (P_SpawnGlowingLight): (actionf_p1) T_Glow.
	* p_lights.c (P_SpawnStrobeFlash): (actionf_p1) T_StrobeFlash.
	* p_lights.c (P_SpawnLightFlash): (actionf_p1) T_LightFlash.
	* p_lights.c (P_SpawnFireFlicker): (actionf_p1) T_FireFlicker.
	* p_floor.c  (EV_DoFloor): (actionf_p1) T_MoveFloor.
	* p_floor.c  (EV_BuildStairs): same (twice).
	* p_doors.c  (EV_VerticalDoor): (actionf_p1)T_VerticalDoor.
	* p_doors.c  (P_SpawnDoorCloseIn30): same
	* p_doors.c  (P_SpawnDoorRaiseIn5Mins): same
	* p_doors.c  (EV_DoDoor): same
	* p_ceilng.c (EV_CeilingCrushStop): (actionf_v)NULL.
	* p_ceilng.c (EV_DoCeiling): (actionf_p1)T_MoveCeiling.
	* p_ceilng.c (P_ActivateInStasisCeiling): same.
	  These gave g++ errors, but  have been ignored by gcc.

	* r_data.c (R_PrecacheLevel): (actionf_p1)P_MobjThinker.

	* p_saveg.c:  conversions (actionf_p1)T_Whatever.

	* p_tick.c: cast (actionf_v)(-1).

	* p_telept.c: yet another (actionf_p1)P_MobjThinker.
 	
	* p_mobj.c (P_MobjThinker): cast (actionf_v)(-1).
	* TODO:  decent NOP/NULL/Nil function pointer.
	  I'd introduce a global A_NOP() function that
	  chokes up an error message. 
	  Why -1 instead of NULL?

	* p_enemy.c: conversions (actionf_p1)P_MobjThinker.

	* d_think.h/info.h:  think_t is essentially
	  the same action function pointer stuff.
	  I moved the definitions from info.h to
	  d_think.h, and aliased them with a typedef.
	  Now more changes needed.

	* p_enemy.c (successor, predecessor): new LUT,
	  to provide increments/decrements for enum
	  dirtype_t, as g++ complaints:
	  "no post-increment/decrement operator for type"

	* Makefile (CC): okay, tried "g++" once more.
	  A few errors (above). Plus shitloads of warnings
	  (obviously, better "unused" checking with C++,
	   lots of the usual int2enum suspects, implicit
	   declarations, the works).
	 

	* p_mobj.c: action.acp1 used accordingly.
	* p_pspr.c: action.acp2 used accordingly.
	* TODO: info.c:144 warning
	  "missing braces around initializer for `states[0].action'"
 	
	* info.h/info.c: some experimental stuff on
	  action function pointers.
	  
	* TODO: still some sound glitches at startup.
	* i_sound.c: few more cleanups. Made mixing use
	  channel loop instead of unroll, set mixbuffer
	  to zero ot start.
	  Removed some more DOS leftovers (8bit),
	  kept some as comment.

	* hu_stuff.c (HU_Start):
	  More gamemode changes. As in d_main.c, I
	  decided to use DOOM2 as default whenever
	  one needed - it was sold most, and had the
	  superset of items, enemies and monsters.

	* TODO: the handling of WAD specific messages
	  like HU_TITLE, HU_TITLE2, HU_TITLEP etc.
	  should definitely be removed.

	* d_main.c (CheckBetaTest): 
	  Removed outdated, DOS specific BETATEST stuff.
	  d_main.c (IdentifyVersion):
 	  Numerous changes to gamemode handling. 

	* TODO: currently, french language is enabled by
	  detecting an doom2f.wad - yet it needs FRENCH
	  define at compile time. I removed most language
	  stuff, and propose handling that at runtime,
	  using a switch in the config file. Well,
	  mission specific texts won't work outside the
	  WAD anyway.

	* TODO: along the same lines: I suggest removing
	  the misc. devparm switches as well - lots of
	  redundancy not needed anymore.

	* Makefile: finally added a doomstat.c for all
	  the global state variables listing internal
	  engine configuration. Right now, these are
	  scattered everywhere. Declaration to be found
	  in doomstat.h header.

	* f_finale.c (F_StartFinale): 
	  Reworked the entire finale handling based on
	  game mode enum.

	* doomstat.h:
	  Global variables for game mode and language.
	  Removed old booleans.

	* doomdef.h: GameMode_t and Language_t enum added.
          Boolean for language was kinda limiting to 2
	  alternatives (french, english), and five boolean
	  plus #define SPECIAL for game version is just ugly.
	
	* wi_stuff.h: SPECIAL switch compiles two
	  different EXE's, one for 3 episodes of 9 maps
	  each (DOOM 1 registered), one for 4 episodes
	  of 9 maps each (DOOM 1 retail/FinalDOOM).
	  Implicitely, the DOOM2 config (one episode,
 	  34 missions) is handled. How is the german
	  edition (32 missions only) done?
	  Frankly, this is a mess. The problem is that
	  intermission (animated as in DOOM 1, simple
	  backdrop as in DOOM2) as well as certain
	  items (double shotgun) as well as certain
	  rendering stuff (sky texture) depend on this.

	  Plus, it ties into runtime flags as "commercial"
	  as well. Yuck.
	
	  Each change will change the game. Postponed.

	* d_net.c,m_misc.c: removed last two NeXT remains.

	* d_englsh.h,d_french.h,d_main.c,m_misc.c,r_draw.c,v_video.c:
	  more WATCOM remains removed. Kept some stuff that
	  handeld the blocky mode/detailshift in DOS, which
	  is n.a. in Linux - but probably not worth fixing.

Sat Dec 20 15:16:51 1997    <bk@gamers.org>

	* Bug: core dump when using doom.wad or doom1.wad
	  without a "-file UNUSED/doom2.wad". Version
	  dependend handling of stuff (double shotgun)
	  comes to mind.

	* doomdef.h: 
	  SNDSERV enables external sound server
	  support. SNDINTR enables internal sound
	  output with timer (asynchronous). Default
	  is internal, synchronous.

	* i_sound.c (I_HandleSoundTimer): 
	  Okay, the plasma/double shotgun sound bug
	  (crapyy sund when firing nose-to-wall) is
	  obviously a problem with blocking at
	  refresh - smaller screen size makes it go
	  away.
	  I won't do threads w/o a proper gdb, and
	  I can't do whatever Dave Taylor did with
	  LinuxQuake w/o the sources, thus I broke
	  down and implemented a timer based solution.
	  Seems to work fine, given the fact that
	  this is the first time ever I implemented
	  sound handling.

Fri Dec 19 10:02:48 1997    <bk@gamers.org>

	* m_menu.c/i_sound.c/s_sound.c:
 	  Removed a few more inconsistencies due to
	  old internal sound handling (DOS),
	  external (Linux sndserver), and
	  new internal (the unfinished merge of
	  both the former).
	  The Options/Sound/Music volume menu is
 	  accessible now. It was due to an internal
	  scaling of the menu (effective range 0-15),
	  up to 0..120, by multiply with 8 scattered
 	  all over the place, that we got a
	   v_video.c: I_Error ("Bad V_DrawPatch")
	  Now I am using the menu resolution
	  everywhere, and scaling should only be done
	  in the actual mixing/output.
	
	* OK, obviously this hasn't been updated in months.
	  This is because: a) most of the time nothing
	  happened, and b) when something got done, it was
	  too much to keep track of it by CVS and/or ChangeLog.

	  Basically, what happened in the meantime is that
	  I did not find a publisher who believed that the book
	  sales would be worth doing it. Within the limited
	  amount of time that I could dedicate to a project
	  that will not generate any revenue whatsoever,
	  I spent some time on cleaning up the Linux code
	  base which works, essentially. I might or might not
	  be able to participate in a Mesa+Voodoo+Glide based
	  GLDOOM port for Linux. I won't waste a minute on
	  Win32 without getting paid for it.
  
	  Because of the legal issues involved with the
	  DMX sound library id licensed for DOS DOOM, Linuxdoom
	  is the only code base that has sound support at all.
	  Other UNIX ports (SGI, Sun) could probably be revived
	  and integrated w/o too many problems. There is no
	  Win32 port - I never had access to WinDOOM or
	  Jim Dose's GLDOOM sources. There is no Linux
	  OpenGL (read: Mesa) support yet - that'd involve
	  internal changes which will best be done after a
 	  public source release.

	  John Carmack opted for a release of the Linux code.
	  I have removed all DMX references I could get a
	  hold of, but preserved some of the original
	  sound handling within DOOM that interfaced
	  with DMX. Linuxdoom (like previous UNIX ports)
	  used a separate sound server binary. I did some
	  work on putting the sound server module back into
	  the engine. It works, but shutdown (pending sounds),
 	  and sound output parallel to refresh (blocking)
	  is crappy, and there is a problem with double
	  shotgun and plasma at close distance (as well as
	  with lots of other noises going on). As the
	  mixing code is identical to the separate
	  soundserver, and as it doesn't seem to be a
	  blocking issue, I am currently at a loss - I
 	  wonder whether the IPC communication with the
	  soundserver process introduced a delay that
	  changed behaviour, or whether I simply overlooked
	  a bug. I am currently lacking the time to track
	  this down, so I am keeping both internal and
	  soundserver source.

	  I did remove DOS and Watcom specifics. I did also
	  remove the texture mapping and fixed point assembly.
	  From my experience, it isn't worth the trouble
	  to ue GCC inline assembler, as performance of 
	  the same loop written in C is perfectly sufficient.
	  On demand I will put both assembly modules into some
	  documentation, as they are probably of historic
	  interest.

	  There is no Sun DGA, Irix, or other non-Linux stuff
	  in this code base (at least, not intentionally). 
	  They will be back when ports to other UNIX 
	  environments will be merged back (I can't do 
	  testing, and the modules were separate and not
	  consistent, so I refrained from wasting time on
	  this prior to a public release).

	  While I made only minor changes to the actual code
	  (some fixes, some cleaning up of SHM and audio),
	  I did a huge amount of shuffling around. I
 	  introduced many more header files and modules,
	  some of them laughably small (doing these changes
 	  is bound to screw up CVS, so no CVS record anymore
	  for the time being). I would introduce even more
	  separation if I had the time. Splitting the
	  animation/AI/behaviour code that defines 
	  "DOOM - The Game" into a separate game.so (like
          Quake2 does) should definitely be done. Separating
	  a ref_soft.so aka "DOOM - The Engine", and defining
	  a clean interface prior to introducing a ref_gl.so
	  is recommended as well.

	  I am going to purge some more leftovers, remove 
	  the obsolete CVS history except for comments,
  	  and try to clean up the last "implicit declaration"
 	  and "unused variable" warnings. Except for enabling
	  cheats in nightmare (to have more fun while testing),
	  I did not change the game mechanics at all. I would
	  strongly advise against doing so w/o the proper
	  separations suggested above. I will not waste time
	  on fixing detail and blocky mode, lack of resize,
	  or other stuff that it better addressed by a proper
	  GLDOOM port.

	
Sat Aug 16 08:07:16 1997    <bk@hal.gamers.org>

	* p_pspr.c:
 	  Moved the sprite animation stuff from doomdef.h here.

	* info.h:
	  Added #ifndef __INFO__ for multiple inclusion. I am
	  not going to deal with multigen, or changing the
	  original DOOM monster animation anyway.

	* p_spec.h/c:
 	  Moved anim_t etc., locally used only. There is
	  another anim_t in wi_stuff.h/c, now local as well,
	  so collisions on header inclusion should not occur.
          #include "doomdef.h"
          #include "doomstat.h"
	  these should now be topmost includes.
	
	* doomstat.h, doomdef.h, wi_stuff.h, d_player.h:
	  I moved wbstartstruct_t to d_player.h, and wminfo
	  to doomstat.h. Basically, I will try to move all
	  global state related stuff into doomstat.h, and
	  all data structures defined for state variables
	  into doomdef.h - this will be kinda greek tragedy,
	  and never finished, but a body can try.

	* wi_stuff.h/c, wi_data.h: 
          Removed wi_data.h, put all local stuff blah... see
	  below.
          I have found several unused global variables,
	  started outcommenting them with //U, will remove
	  them later. It might be Watcom/PC stuff, or
	  somebody put the actual numbers into the implementation
	  instead of using STARDIST, ANIMPERIOD & Cie.
	
	* st_stuff.h/c: from doomdef.h, local stuff moved
	  into st_stuff.c, etc.
	  In the current revisions, I am tolerating warnings
	  of the "implicit declaration" kind - the linker
	  resolves the stuff, and it will be handy in 
	  unmangling the modules once the headers contain
	  only the globally visible stuff.

	* am_map.h/c, am_data.h:
 	  Removed am_data.h, put all local stuff into
	  am_map.c, moved globally needed headers from
	  doomdef.h into am_map.h.

	* p_saveg.h, p_setup.h, p_tick.h:
 	  created, stuff from doomde.h moved there

	* d_main.c, d_net.c, doomdef.h: 
	  Decided to dump mprintf, as only needed for
	  Watcom support which is not going to happen.

	* doomdef.h: 
	  Moved function prototypes to appropriate headers:
	  d_main.h, d_net.h.

Fri Aug 15 16:38:53 1997    <bk@hal.gamers.org>

	* doomstat.h:
	  added a few more comments, regrouped some of the
	  state variables.

	* doomdata.h: added a few more comments.

Thu Aug 14 10:38:37 1997    <bk@hal.gamers.org>

	* g_game.c (G_DoLoadLevel): 
	  copied the skyflatnum determination here, from
	  the R_InitSkyMap - once should be sufficient.

	* Makefile, r_sky.h/c: 
	  added r_sky module. The sky handling was scattered
	  over r_bsp, r_main, r_plane, doomstat.h...

	* r_bsp.c, r_main.c, r_segs.c:
 	  Removed RD_* calls from R_debug.m, NeXT switches.

	* r_local.h:
	  Removed the R_debug.m NeXT specific debugging
	  code headers. Removed "drawbsp" flag from
	  here, and r_main.c, too.

	* r_data.c: 
	  Started to remove NORMALUNIX switches, using
	  LINUX instead. Basically, different UNIX
	  platforms using the same code should simply
	  be ANDed in the #ifdef switches.

	* r_draw.c:
	  Removed some more, but not all WATCOMC support.
	  There is an unresolved problem with the fuzzy
	  blitting in the lowres (blocky) modes - either
	  the "detailshift" flag triggered lowres mode
	  will be removed, or the bug has to be fixed.

	* r_bsp.h, r_draw.h, r_things.h, r_data.h,
	  r_segs.h, r_main.h, r_plane.h: 
          Created from r_local.h. 
	
	* Back to work.
	  Till March 22nd, a lot of source shuffling and addition
	  of new header files, separating stuff, and creating
	  new, smaller modules. Some Watcom/PC/DMX/NeXT etc.
	  related stuff got removed, but not all (yet). None of
	  this ended up in the Log (sorry) or the revision control
	  (CVS is not well suited while number of files and
	  respective names change a lot, especially if stuff gets
	  deleted and/or re-introduced).
	  Major change: part of the sound code got copied from the
	  separate Linux sndserver sources to the linuxdoom source.
	  Re-integration and removal of sndserver pending.
	  Nothing of importance happend since then (priorities).

Mon Feb  3 16:41:05 1997    <bk@gamers.org ()>

        * m_misc.c:
          Created m_argv, m_random and m_bbox, kept remains in m_misc
          for the time being. Misc. files changed to include only
          necessary modules. Moved bbox definitions from doomdata.h. 

        * m_menu.h:
          Created from doomdef.h. Misc. changes in dependend modules.
          I am not going to list every affected file from now on.
          See Log entries within each file. 

        * dstrings.h:
          Now handles multi-language support and switches.
          So far, only english (default) and french are available. 

        * d_englsh.h: 
          Created from dstrings.h. 

        * g_game.h:
          Created, from doomdef.h. 

        * am_map.c, st_stuff.c, wi_stuff.c: 
        * Makefile: 
          Added m_cheat, removed dutils. Doubly linked list stuff unused.

        * m_cheat.h, m_cheat.c:
          Created, basci cheat string scrambling and check, from dutils.h
          and dutils.c. 

        * doomdef.h
          Moved screen declaration to v_video.h.

        * dutils.h, dutils.c
          Remode code for f_wipe.h and f_wipe.c.

        * Makefile
        * d_main.c,
          Added f_wipe files.

        * f_wipe.h, f_wipe.c: 
          Created, screen wipe/melt at mission begin, from dutils.h
          and dutils.c.

        * d_textur.h:
          Created from doomdata.h. Separates all the patch/texture
          defintions. Needed for v_video module. 

        * r_local.h, wi_stuff.h, st_lib.h, hu_lib.h: 
        * i_x.c, d_main.c, m_menu.c, m_misc.c: 
          Added v_video.h.

        * v_video.h:
          Created. Using headers from doomdef.h. Forward of patch_t.
          Moved bool and byte to doomtype.h.

Thu Jan 30 20:50:16 1997    <bk@gamers.org ()>

        * doomtype.h:
          Created, for fixed_t. Should add angle_t here, too.

        * tables.c: 
          Added SlopeDiv from r_main.c, added all defines and typedefs
          related to basic trig table use here, removed it.
          Currently "tables.h" is included in doomdef.h and
          r_local.h, too. This is not too cleanly separated, but
          we have to start somewhere, right?

        * tables.h:
          Created from doomdef.h.
          Note that tables.c had fixed size tables, while doomdef.h
          calculated from the value of FINEANGLES. In addition,
	  entries were given as either "int" or "fixed_t". Bad boys.  

        * z_zone.c: 
        * s_sound.c: 
        * hu_stuff.c: 
        * st_lib.c, st_stuff.c: 
        * wi_stuff.c: 
        * w_wad.c: 
        * r_things.c, r_plane.c, r_draw.c, r_data.c: 
        * p_tick.c, p_mobj.c, p_spec.c, p_setup.c, p_lights.c, 
          p_plats.c, p_floor.c, p_doors.c, p_ceilng.c: 
        * am_map.c: 
        * m_misc.c, m_menu.c: 
        * g_game.c: 
        * d_main.c: 
        * f_finale.c:
          Added #include "z_zone.h". 

        * z_zone.h: 
          Created, from stuff in doomdef.h

        * CVS checkin. Reformatting run, last one.
          Took a week to go through all the sources, w/o even
          looking to closely.

        * st_stuff.c (ST_Responder): 
          Removed a first tiny bit of redundancy (NO_CLIP checks).
	  Should remove idspispod completely, later.

Wed Jan 29 19:53:43 1997    <bk@gamers.org ()>

        * Another one, while we are on it. All S (Sound) files.

        * CVS checkin. Reformatting run, all R (Refresh) files.

        * r_draw.c (R_DrawSpanLow): 
          The non-Watcom, non-asm lowres mode was just a copy
	  of the default mode. As detailshift was used to scale
	  the image down, lowres mode just filled the left half
	  of the buffer.
        * r_draw.c (R_DrawColumnLow): 
          Tried the same hack for walls, horribly broken.
	  Postponed. 

Tue Jan 28 19:32:48 1997    <bk@gamers.org ()>

        * CVS checkin. Another reformatting run. Did all P files.

        * p_spec.c: P_FindNextHighestFloor
          The number of adjoining sectors is limited to 20, because
	  of a temporary LUT needed for determining lowest height
	  in adjacent sectors. No overflow checking is done.

Sun Jan 26 08:41:21 1997    <bk@gamers.org ()>

        * Another CVS checkin of a formatting run.
          D,F,G,HU,I,M have been changed.

        * Note: in initial and current release,
           linuxxdoom -3 -file plutonia.wad, idclev 12
          produces a Segmentation fault.

Wed Jan 22 14:03:00 1997    <bk@gamers.org ()>

        * m_menu.c:
           initializer-string for array of chars is too long (skullName)
           warning: unused parameter `int choice' (a couple of times)

        * Attempt to compile as C++. Loads of warnings, a couple of errors.
          p_enemy.c (P_Move):
          r_things.c (R_ProjectSprite)
           `catch', `throw', and `try' are all C++ reserved words,
           thus changed "try" to "try_ok". Fixed.
          p_pspr.c: In function `void P_SetPsprite(struct player_s *, ... )':

           There are more like this. Going to be a tough one.

Wed Jan 22 12:15:00 1997    <bk@gamers.org ()>

        * CVS checkin of purification run. Sources now compile
          without any "-Wall" warnings.

        * Note: with -file "tnt.wad", we get an "Error: Bad V_DrawPatch"
          abort each time we enter an exit. Invalid or missing
          intermission screen?

        * Makefile (CFLAGS): added -Wall, first purification run.

Tue Jan 21 22:00:00 1997    <bk@gamers.org ()>

        * doomdata.h (__BYTEBOOL__):
          Use builtin ANSI C++ bool.

        * d_main.c (IdentifyVersion): 
          Bug fix: insufficient malloc created errors in malloc/realloc
	  calls later on. Welcome to the risks of Copy'n'paste. 

Tue Jan 21 13:20:05 1997    <bk@gamers.org ()>

        * First formatting checkin.
          A word of explanation: prior to making any changes to the
	  source, a couple of formatting runs will be made, followed
	  by some purification runs.
	  For this run, the Emacs mode selection line has been changed
	  to use C++ style indenting (cc-mode.el).  Each file has
	  been automatically reformatted using Emacs indent-region.
	  A few files have been changed manually already (i.e.,
	  comments, use of tabs).
	  Warning: using "diff" to compare files of different states
	  during the reformatting will not give useful results.

        * hu_stuff.c: 
          fixed "assignment discard const", the last remaining error
          message with default compilation.
                      

Sun Jan 19 14:27:06 1997    <bk@gamers.org ()>

        * Makefile:
          Minor fix for sndserver target, removed linuxsdoom target
          for the time being, added CVS header (kind of).

        * Initial CVS checkin. 

        * soundsrv/irix/linux/sun.c: 
          Changed includes (irix.h removed, soundsrv.h included).

        * i_svga.c: 
          Changed to DOS 8+3.

        * soundsrv.h/c:
          Changed to DOS 8+3, included irix.h in soundsrv.h.

        * r_local.h:
          Same for PI, include math.h with Linux.

        * doomdef.h: 
          Got rid of multiply defined warnings for Linux, 
          included values.h.

        * FILES2:
          created a commented list of all files, removed a few
          more files (sndserver test, NeXT leftovers, DMX header).
          Identified the following main modules (see FILES2):
          AM, HU, M, P, R, S, ST, W, WI. Some stuff is separate
          (Z, F), some not clearly separable (G, D). System specific
          interfaces are in I. Some of the latter replace i_main.c
          (i.e. the void/int main(argc,argv) call), e.g. SVGA,
          others (X11, SHM, DGA) don't. There is a certain amount
          of overlap, and the largest module (with possibly most
          overlap) is P - playing, i.e. all the games state and
          animation handling.
          Dithering is currently not used.

Sat Jan 18 15:14:41 1997    <bk@gamers.org ()>

        * r_draw.c: 
          fixed !defined(USEASM) lines for R_DrawColumn/Span.
          Removed fpfunc.o/S from Makefile, now compiling
          X11 w/o any assembler.
          Got a running linuxxdoom again. We are in business.
          This source is going to be used for the initial CVS
          check in.

        * Tried a quick hack compiling it as COFF a.out instead
          of ELF, with "gcc -b i486-linuxaout". Same linker
          errors. 
          Tried removing -DUSE_ASM. Still using fpfunc.S.


        * Tried linuxxdoom.
          Compile run: some warnings (redefinition of MAX/MIN
           SHORT/INT/LONG) in doomdef.h and (PI redefined)
           r_local.h.
          Link run: crashed, undefined references in 
            d_main.c: undefined reference to  `FixedDiv2'
            am_map.c:  undefined reference to `FixedMul'
            r_main.c:  undefined reference to `R_DrawColumn'
            r_main.c:  undefined reference to `R_DrawSpan'
            r_plane.c: undefined reference to `FixedMul'
            
          This stuff is defined in fpfunc.S (Fixed point) and
          in r_draw.c (assembler in tmap.S not used).
          However, "nm," shows that r_draw.o does not include
          the drawing functions (see below - USE_ASM).
          Furthermore, the global symbols in fpfunc.S begin
          with an underscore, "_FixedMul" and "_FixedDiv2".
 
          More problems within fpfunc.o: undefined references to 

             `_dc_yl'      `_dc_yh'
             `_ylookup'
             `_centery'
             `_dc_x'
             `_columnofs'
             `_dc_iscale'
             `_dc_texturemid'
             `_dc_source'
             `_dc_colormap'

             `_ds_y'       `_ds_x1'      `_ds_x2'
             `_ds_xfrac'   `_ds_yfrac'
             `_ds_xstep'   `_ds_ystep'
             `_ds_colormap'
             `_ds_source'

          Again, underscore problem.
          Note: tmap.S currently obsolete, as somebody pasted all
          the texture mapping assembly into fpfunc.S. Gotta clean
          that up.

        * Created initial release from CD sources, created ChangeLog.
          Let the games begin.
