constructions like (dataMask & ~3) was used to protect against out-of-bound load/store when address is 4-byte closer to dataMask
but at the same time it effectively cut low address bits for ALL load/store operations which is totally wrong in terms of conformance to ALLOWED (i.e. generated by q3lcc from C sources) low-level operations like packed binary data parsing
Save argument instead of using a pointer to cmd token memory that
might be overwritten when Cmd_TokenizeString() is called.
No known method for causing the issue without engine changes.
Cmd_TokenizeString() is called by FS_PureServerSetReferencedPaks()
in CL_Disconnect() but it's not an issue because the string is
blank.
Thanks @mickael9.
Check for truncated paths which could allow loading a library with
a non-standard extension. Also provides a better message for why a
valid library with a long path would fail to load.
Processing a callvote command after a vote passed to change maps but
has not been executed yet will result in 1) map change immediately
happening 2) after new map loads players have vote HUD messages but
Game VM doesn't have a vote in progress. The phantom vote status will
only be removed if players start a new vote or run vid_restart.
The underlying issue is that a second callvote sets vote config
strings but a map change is executed before they are sent to clients.
Resulting in clients getting "cs" reliable commands with the config
string changes _after_ the map change. Out of sync config strings.
Even if the underlying issue was fixed, the second vote would be lost.
So it's best to not force a map change to happen immediately anyway.

- Paths to search for mods are now specified in an array
- Mods can now consist solely of ".pk3dir" folders and still be
considered valid
- The function now has a consistent style
+seta, +sets, and +setu were ignored because Com_AddStartupCommands
thought Com_StartupVariable handled it.
+set didn't allow value to be multiple tokens which due to Unix shell
unintuitively removing quotes causes the variable to only be set to
the first token. This could be worked around by escaping quotes
ioq3ded +set g_motd \"hello world\"
but it doesn't match behavior of other start up commands (which now
includes seta, sets, and setu) that use all tokens.
source_t filename and includepath are 1024 but MAX_PATH is 64. As far as
I know the paths don't exceed that so this probably doesn't fix anything.
Similar changes were already made to l_script.c so this makes things
consistent. This was found because it was fixed in RTCW's code.
MISSIONPACK define is already required for this file or else it triggers an #error at the top of the file - removing redundant test that will never occur.

Modern compilers either ignore the register storage class when
generating code, or generate better code without it, so just remove
most of them.
The remaining uses are in third-party bundled libraries (libjpeg, zlib),
and in a PowerPC-specific inline function consisting of inline
assembler (because I'm not 100% confident that it doesn't have
some practical use there).
If ERR_DROP during Com_GameRestart after shutting down client, Com_Error
needs to restart the client otherwise there is just a black window. Also,
clear the game restarting flag in Com_Error otherwise it's not possible to
run Com_GameRestart again later.
I don't know of a way to trigger ERR_DROP, in FS_Restart for instance,
without engine changes however.
Offer to restore settings when loading a mod that crashed, not the first
mod that gets loaded after a crash. Before the first mod loaded (usually
baseq3) would get the option even if missionpack or some other mod crashed.
- Make pid files separate for each fs_game.
- Remove/write pid every time switching fs_game.
- Create path before writing pid file otherwise it fails on first run.
- Show mod description.txt or fs_game instead of engine name in abnormal
exit message.
- Check com_fullyInitialized in Com_Error before removing PID,
otherwise "ioquake3 --version" segfaults when accessing fs_gamevar->string
(plus not fully initialized isn't really a normal shutdown).
As with the other branch of the if/else, each element of
foundPlayerServerNames is in fact the same size as each element of
foundPlayerServerAddresses, so it was fine; but it's better to make
it obvious that we are using the right array sizes.
This function is used in the Team Arena menus
I don't think it's actually possible to reach this line with
foundPlayerServerNames < 1, because by the time we get here we have
set it to 1 + the actual number of servers; but if we did, it would
clearly underflow into foundPlayerServerNames[-1], which would be
undefined behaviour. gcc 6 diagnoses this with a warning:
code/ui/ui_main.c: In function ‘UI_BuildFindPlayerList’:
code/ui/ui_main.c:4138:16: warning: array subscript is below array bounds [-Warray-bounds]
Also correct the sizeof() invocation to make it more obviously
correct (in fact the buffers for names and addresses happen to both
be of size MAX_ADDRESSLENGTH, so it was fine, but it's good to be
obvious).
Given an array b[] of length n, pointers to &b[0]..&b[n] are defined
(where only &b[0]..&b[n-1] can be validly dereferenced). &b[-1], or
equivalently b-1, is not something we can use in valid Standard C.
gcc 6 diagnoses this as:
code/client/snd_wavelet.c:33:9: warning: array subscript is below array bounds [-Warray-bounds]
and might take this undefined behaviour as permission to emit
"more efficient" object code that is not what the author expected,
for example nothing at all. Use a macro to fake a 1-based array instead.
The goal of reproducible builds is that a rebuild of the same source
code with the same compiler, libraries, etc. should result in the same
binaries. SOURCE_DATE_EPOCH provides a standard way for build systems
to fill in the date of the latest source change, typically from a git
commit or from metadata like the debian/changelog in Debian packages.
This does not change anything if SOURCE_DATE_EPOCH is not defined;
the intention is that a larger build system like a Debian package
will define it.
Please see https://reproducible-builds.org/ for more information about
reproducible builds.
Bot's lastkilledplayer was set to -1 after carrying out an ordered kill.
Later in BotChat_Random() the PlayerName function was passed -1 which
caused a "Error: PlayerName: playernum out of range" message.
I think the reason it was set to negative one is so that if the bot is
ordered to kill the player again, the bot will not say it's done and
drop the goal. Though, if the bot killed the player based on it's own
decision, it will just say it's done and drop the goal (bug?).
Let's check the time of the last kill to see if it happened since the
team order was received instead of setting lastkilledplayer to -1
after completing the team ordered kill. This fixes bot dropping goal
if target player was the last player they killed and the PlayerName
out of range error.
At the end of CL_RunCinematic, RoQShutdown sets currentHandle to -1.
This causes the return at the end to be return cinTable[-1].status.
Use return FMV_EOF when RoQShutdown is called.
I think FMV_EOF should be returned instead of FMV_IDLE which is set in
RoQShutdown because RoQShutdown is clearing out state so it can be reused
for a new cinematic.
The return value isn't actually read by the ioq3 client, renderers,
cgame, or ui.
Make Yes/No, Multi, Slider, and Bind items allow enter key to change
value without mouse over item. Add support for left and right arrow keys
and joystick button 1-4 to Yes/No, Multi, and Slider and many item
specific 'ownerdraw' key handlers.
Listbox still requires mouse hover and Team Arena main menu requires
mouse hover to get anywhere...
Enabling K_JOY1-4 to select in default key handler also caused additional
mouse button (K_AUX1-16) to select, which is done in q3_ui as well. Both
handle K_AUX equally badly (not treated as a mouse button and not handled
by item specific key handlers), so it's probably fine.
Explicitly set cull type for skybox to front, instead of using whatever
cull type the previous shader used (which could result in the skybox
not being visible due to only drawing back faces). The sky cloud stages
set the cull type so they are not affected by previous cull type.
Server/client VoIP protocol is handled by adding new cvars
cl_voipProtocol and sv_voipProtocol, sv_voip and cl_voip
are used to auto set/clear them. All users need to touch
are cl/sv_voip as 0 or 1 just like before.
Old Speex VoIP packets in demos are skipped.
New VoIP packets are skipped in demos if sv_voipProtocol
doesn't match cl_voipProtocol.
Notable difference between usage of speex and opus codecs,
when using Speex client would be sent 80ms at a time.
Using Opus, 60ms is sent at a time. This was changed because
the Opus codec supports encoding up to 60ms at a time.
(Simpler to send only one codec frame in a packet.)
The number of draw surfaces was range checked against number of surfaces for
the current view but needs to check total for the frame otherwise can read
past the end of the tr.refdef.drawSurfs array when there are multiple views.
Reserve space for end of list and swap buffer commands. These are absolutely
required and cannot be dropped. Dropping swap buffer command causes screen
to not update and possible crash from drawsurf buffer overflow if not enough
cmd buffer space for many continous frames.
Text_Width's scale argument will be multiplied by glyphScale, so don't
pass useScale that is already multiplied by glyphScale as this makes
the scale too big.
GNU platforms (Linux, kFreeBSD, Hurd) have endian.h to determine
endianness, so all architectures except x86_64 are in fact treated
identically, except that their ARCH_STRING is different.
The ARCH_STRING must always be identical to the ARCH from the Makefile,
otherwise the engine will not find its cgame, game and ui plugins
under their expected names and startup will fail. If we pass it in
from the Makefile, then an identical value is guaranteed, and we can
get rid of an increasingly long list of defined(__some_cpu__) tests.
The one remaining quirk is that we test __x86_64__ to determine
whether to define idx64; I've kept that, but separated it from
the ARCH_STRING.
On non-Linux platforms we only support a few architectures anyway,
so keeping the list up to date is less of a burden; *BSD porters
could probably use the same technique to get support for lots of
architectures with little effort, but I have not done that here,
because I cannot test it.
Windows must continue to support preprocessor-based architecture tests
in any case, so that the MSVC solutions (which do not use the Makefile)
can continue to work. However, Windows only runs on a few CPU families,
so this shouldn't be a significant burden in practice.
When cross-compiling, the tools are compiled for the build architecture
(COMPILE_PLATFORM, COMPILE_ARCH) rather than the host architecture
(PLATFORM, ARCH), so define ARCH_STRING to COMPILE_ARCH on a GNU
COMPILE_PLATFORM.
MASK_REG in EmitMovEDXStack would incorrectly emit asm if 'andit' was 0.
'andit' would never be 0 though so it wasn't causing issues.
Found by Coverity.
Windows' Sys_ListFiles would add files that contain the extension anywhere,
not only at the end of the file name.
Example: "word.pk3omghacks" use to be loaded as a pk3 file.
My last commit made it so that CGame "waterlevel 1" is feet in water,
but before it was erroneously about waist deep in water. The places
where it is checked it is suppose to be view position underwater.
Change comparisons to use correct value for view position underwater.
CG_WaterLevel() added lerpOrigin to itself instead of adding view height
when checking for waterlevel 2 and 3. This did not cause issues because
ioq3 only compared the calculated waterlevel to more or equal to 1.
