Thu Jan 30 20:50:16 1997    <[e-mail] ()>

        * 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    <[e-mail] ()>

        * 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    <[e-mail] ()>

        * 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    <[e-mail] ()>

        * 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    <[e-mail] ()>

        * 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 *, ... )':
           too many arguments to function
           No convenient fix - state->action is declared void action(),
           but called w/o, with one, or with two parameters.
           There are more like this. Going to be a tough one.
	   Union of pointers?
          Postponed.

Wed Jan 22 12:15:00 1997    <[e-mail] ()>

        * 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    <[e-mail] ()>

        * 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    <[e-mail] ()>

        * 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    <[e-mail] ()>

        * 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    <[e-mail] ()>

        * 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.
