The values passed to SDL are just the minimum required. Get actually
values of colorbits, depthbits, and stencilbits from SDL instead of
assuming that the engine got exactly what it asked for.
The r_colorbits cvar still exists and gfxinfo reports it works on
Debian Jessie in both git master and building the commit where I
removed r_colorbits from q3_ui. So it does indeed control something.
Maybe I expected 16-bit color to look different? I don't know.
This reverts my commit 8e689739f4
from August 11 2011.
Loading a 1024-byte q3history file will fill the whole consoleSaveBuffer
leaving no space for a string terminator. Com_Parse will read at least
one byte beyond the end of consoleSaveBuffer. The written console
history file can only be 1023 bytes (enforced by Q_strcat) so don't
allow loading size of 1024.
If switching to a mod with a shorter q3history file, the data in
consoleSaveBuffer that isn't overwritten will be parsed. So always
add a string terminator.
String not terminated reported by David "devnexen" CARLIER.
cls.glconfig.isFullscreen was not updated when changing r_fullscreen
without a vid_restart. Starting in fullscreen and switching to
windowed mode would not release the mouse.
Mods calling trap_GetGlconfig() after a fullscreen toggle now get
the correct value for isFullscreen. (Note: Mods already got the
correct value at start up and after vid_restart.)

Allows higher download throughput (from ~2 MB/s to ~60 MB/s at 120FPS)
This has no effect for curl versions older than 7.53.0 (for which the
buffer can only be shrunk below 16k)
Fix the output/behaviour of CVAR_CHEAT flagged cvars in case they are
also of type CVAR_LATCH (avoid the early latch case return to make it
work as intended).
This is exact root of q3msgboom bug http://aluigi.altervista.org/adv/q3msgboom-adv.txt
Unfortunately, server still need this ugly '1022 char limit' hack to support unfixed clients in some degree.
And as it affects MSG_ReadBigString() - unfixed clients can still be crashed by 8191-chars long configstrings that comes with gamestate
If client sends wrong serverId but is already active in the world
(CS_ACTIVE) don't resend initial gamestate for the map. This isn't a
valid situation. The player should be CS_CONNECTED or CS_PRIMED.
Resending gamestate to an active player will cause them to respawn
without dying or disconnecting. If the player had a CTF flag it gets
lost until the map is changed or restarted.

In May 2017 the library loading was limited to *.dylib but the macOS
system OpenAL framework does not have dylib extension. So allow loading
files from /System/Library/Frameworks/ as libraries even without dylib
extension.
This is checked in Sys_DllExtension() so that QVM filesystem access will
not allow writing files to /System/Library/Frameworks/ even if homepath
is changed to include it. (Admittedly it doesn't fit the function name
but fits the function description and current usage.)
Allow listing about 273 .arena filenames for loading in q3_ui instead
of only about 136 that fit in a 2048 byte buffer (average 15 bytes per
file name).
The buffer for filename list runs out of space long before the buffer
for arena file content does. There is no warning for file list out of
space but there is a warning for arena file content.
This was requested by a user with many maps.
Team Arena's mpteam6 map has a shader textures/base_wall2/space_concrete
that contains an opaque stage, two non-lightmap blendfunc filter stages,
a blendfunc add stage, and a lightmap stage. The lightmap was attached
to all four of the non-lightmap stages causing the filter stages to
darken the lightmap multiple times.
Change setting up the lightall GLSL shader to only use lightmap if it's
the first stage or not a blendfunc filter stage. Now only the opaque
and blendfunc add stages of the mpteam6 shader use the lightmap.

Newer versions of BSPC such as 2.1h included with the Quake 3 GPL source
code create AAS files containing areas in cluster 0 if the area has no
reachabilities.
The AAS files included with Quake 3 and Team Arena do not contain areas
in cluster 0. It's apparent that BSPC would not create them. Instead it
created clusters with no reachability areas.
It seems the intention was to check if the areanum and goalareanum have
reachable areas using AAS_AreaReachability(areanum) everywhere before
calling AAS_AreaRouteToGoalArea(). This prevents adding cluster 0 to
the routing cache and portal cache. However, it is not checked
everywhere and including some places in the Game VM.
Fix AAS_AreaRouteToGoalArea() instead of trying to wack-a-mole with all
the places that call it.
Cluster 0 access reported by Thomas Köppe (github @tkoeppe) as causing
crashes in rare cases.
A negative timelimit value or a value that would overflow the
multiplication by 60000 caused an endless map change/reload.

By default mingw-w64 uses Microsoft's broken _vsnprintf() in msvcrt.dll.
It can be overriden by defining __USE_MINGW_ANSI_STDIO but let's just
use the same behavior for both MSVC and mingw-w64.

Use an absolute path as required by systemd. Distro packages will need
to change it. (Reported by @andreyv and @zeroxfourc.)
Link to server documentation on the wiki instead of maintaining a subset
in the service file.
Windows API ignores all trailing spaces and periods which can get around
Quake 3 file system restrictions. QVM opening 'uix86.dll.' actually
opens 'uix86.dll' which allows QVM to write native code.
This is done in the low-level Sys_FOpen() instead of the function
directly used by VMs ( FS_FOpenFileByMode() ) in case there are engine
commands now or in the future that can read or write arbitrary files.

My cvar latch system changes prevent the Game VM from changing
g_gametype when the value is out of range due to it being registed in
the engine. It's been pointed out as fragile method of security, which
was still exploitable, by Noah Metzger (Chomenor). It doesn't seem like
this is working out to be a good solution.
The issue of fs_game '..' on server being relicated on client via
systeminfo exploit is still fixed as it's not affected by latch.
There are a few cases from current values of fs_game are used which
ideally should use fs_gamedir char array which has been validated.
Revert "Don't let VMs change engine latch cvars immediately"
Partially revert "Fix fs_game '..' reading outside of home and base path"
Revert "Fix VMs forcing engine latch cvar to update to latched value"
A few commits ago I stopped VM's Cvar_Set() from instantly updating
latched values. Now VM can't call Cvar_Register() afterword to force
latched value to be used.
Reported by Noah Metzger (Chomenor).
VMs could set fs_game to '..' at anytime to access files outside of home
and base path. fs_game sent by server to clients could also be '..' to
access files outside of home and base path.
'..' was not caught by FS_CheckDirTraversal() as it expects filenames
not a single directory.
I've made fs_game be latched to prevent VMs from changing it with no
good way to validate it before it's used. com_basegame and fs_basegame
are now latched as well.
Additionally, it's now possible to change com_basegame while the engine
is running. game_restart or vid_restart will make it take affect.
com_homepath is now CVAR_PROTECTED to prevent VMs from changing it
to a directory traversal.
This requires my two previous commits for preventing VMs from changing
engine latch cvars and only Cvar_Get fs_game in FS_Startup (so CVAR_INIT
isn't added in serveral other places).
