gcc 6 with -Wall -Wextra warns:

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.
