Get all OpenGL functions using SDL_GL_GetProcAddress(). This makes it
easier to cross-arch compile on Linux and add support for OpenGL ES
in the future.
Users still have to supply their own libSDL2 for cross-arch compiling
on Linux. But now the user does not have to re-install libgl1-mesa-dev
package for i386 or amd64 on Debian when switching between compiling
ioquake3 for x86 and x86_64.
If a lightning bolt killed a player or the first shotgun pellet that
hit a player killed them, the shot was not counted as accurate.
Check if shot player is alive for hit accuracy before dealing damage.
Running a server using the client engine would send server snapshots
to loopback and LAN clients each client frame (com_maxfps).
This causes excessive network traffic and likely does not provide new
information to the clients because SV_Frame() won't have run between
the extra snapshots.
This commit restores the original behavior of respecting local/LAN
client's snaps userinfo and sv_fps. The issue was introduced by the
following commit:
Commit ac30d86db0
From: Thilo Schulz
Date: Wed, 13 Jul 2011 17:11:30 +0000
Subject: - Improve snapshot rate and data rate control
Reported by Eugene C.
Fix "Error parsing animation file" messages in UI. Caused by fixing the
handling of missing tokens in animation.cfg parser in a past commit.
Fix new Team Arena torso animation frame numbers in UI.
Add support for fixedtorso and fixedlegs keywords.
Add support for reversed animations (negative numframes).
Disable SDL relative mouse mode when in_nograb is enabled. Relative
mouse mode hides the cursor and it cannot exit the window regardless
of the window's grab state.
This wasn't always the case. SDL before 2.0.4 on GNU/Linux released
the mouse cursor in relative mode. However, SDL 2.0.3/4 on Windows
does not. (I did not test other Windows versions.) So I think SDL
2.0.4 made GNU/Linux X11 behavior consistent with other platforms.
This fixes mouse input being unusable when debuging client crashes
in gdb.
Entering Team Arena's start server or in-game callvote menu causes
arenas to be reloaded. The existing memory is not freed so after
a entering the menus a few times the UI runs out of memory and
crashes.
Just load arenas once when the UI loads like in q3_ui.
- Use common controls 6 so error dialogs use correct visuals on
Windows XP or later!
- Specify running as invoker so Windows doesn't guess if it should
prompt for admin permission on Vista or later.
- Specify compatible with Vista through Windows 10. Tells Windows
not to emulate Vista behavior, not sure if it affects anything.
Makefile automatically runs windres when manifest changes.
After 'Fix floating point precision loss in renderer', Windows x86
client won't load the renderer DLLs. The problem is a 64 bit modulus.
I couldn't find any reports of this online. However, client with
built-in renderer worked with the 64 bit modulus.
Only tested with mingw-w64.
ioquake3.x86_64.exe can't load x86 OpenAL32.dll. Using separate
library names allows shipping OpenAL for both architectures.
Though since the dll name is saved in the config file, using both
clients on the same computer will cause one client arch to always
try to load the wrong OpenAL dll and then fallback to the correct
default OpenAL dll. I guess it could be fixed by using separate
cvar names for s_alDriver.
Don't draw crosshair 0 in Team Arena setup menu. It isn't drawn
in CGame. Wrap cg_drawCrosshair in missionpack menu like CGame
instead of treating as index 0 which is no longer drawn.
Make spectators use green background for team chat box when following
players. The team chat messages are from spectators not the team of
the followed player.
Make spectators draw team chat box even when not following a player.
Only use the crusher for killing the bot's enemy. This doesn't
affect 1v1 very much but prevents the whole team of bots in CTF
from suddenly shooting at the crusher button. Entering the crusher
bounds was basically instant death.
Make bots activate crusher on q3tourney6_ctf and mpq3tourney6.
Check if player is inside the crush bounds instead of below the
crusher. There is a jumppad the goes under it in mpq3tourney6.
SDL doesn't provide exact the exact time that input events happen
so use the earliest possible time that an event could happen.
This make sub-frame input actions such as walking take affect
immediately instead of in the next frame.
Based on patch by Alexander "wareya" Nadeau.
Make callTeamVote check for all command separators like in callVote.
It's not exploitable as the only vote option (leader) always uses an
integer argument.
Also the ioquake3 engine remove command separators from client game
commands in Cmd_Args_Sanitize().
Fix floatTime using float precision instead of double using GCC.
Fix R_BindAnimatedImage to be in sync with function table.
Fix vertexDeform bulge, vertexDeform normals, noise wave function
at high level time.
Revert unnecessary float -> double conversions.
Patch for https://bugzilla.icculus.org/show_bug.cgi?id=5931 by
Eugene C. from 2013 plus recent fix for tcMod rotate.
I merged the changes into the OpenGL2 renderer though the fix for
tcMod turb doesn't translate.
Prevent reading past end of message in MSG_ReadBits. If read past
end of msg->data buffer (16348 bytes) the engine could SEGFAULT.
Make MSG_WriteBits use an exact buffer overflow check instead of
possibly failing with a few bytes left.
Setting cl_renderer isn't a security concern and valid behavior for
a menu to provide. Sys_LoadDLL ensures only libries are loaded and
engine prevents QVMs from writing them.
This commit fixes the vanilla Q3 UI VMs not displaying a server list
when id Software's master server is down.
Originally master 0 for the globalservers command was Internet and
master 1 was MPlayer (defunct). In 2008 ioquake3 changed it so that
master 0 to 4 were five separate master servers with no affect on
original Quake3/Team Arena UI VMs; they continued to get the server
list from master.quake3arena.com.
id Software's master server (master.quake3arena.com) goes down
occasionally. Using ioq3's UI VM additional master servers can be
accessed but players using the original UI VMs are unable to get a
server list.
In order to fix the original UI VMs in Quake3/Team Arena's pk3s this
commit makes 'globalservers 0' fetch all master servers. So players
get a combined list of id Software's and ioquake3's master list. Or
just ioquake3's list if id Software's master is down.
Getting lists from individual master servers using globalservers has
changed from 0 through 4 to 1 through 5 to accommodate using 0 for
other purposes. This commit modifies ioq3's UI code to support the new
values for globalservers command.
A side affect of these changes is that UI VMs based on ioq3 since 2008
will have Internet1 fetch all master servers and Internet2 request
sv_master1 instead of sv_master2 and so on. It may be worth noting that
getting server list from masters 3-5 could not be done using ioq3's UI
before 2011.
The Team Arena code for giving defense bonus for fragging player
who recently damaged a skull carrier unintentionally applied to
the flag carrier.
The skull carrier case would of been handled by the flag carrier
block above it. However, Harvest mode doesn't call
Team_CheckHurtCarrier() so the skull carrier defense bonus does
not work.
This restores the pre-Team Arena behavior of not giving defense
score bonus to flag carrier.
Fix copy-paste error in the original Quake 3 code. The wrong values
are used for v1 and v2. v2 was previously set to distance of attacker
to flag base; which should be handled already.
The game now gives defense score bonus to player when they frag an
enemy near their team's flag carrier while the player is more than
1000 units from the flag carrier.
This may also fix not giving defense bonus when near carrier due to
checking if carrier and enemy (instead of attacker) are in PVS.
Found by @Razish.
Models don't have a surface limit; skins shouldn't either. Some player
models require more than 32 surfaces since vanilla Quake 3 did not
enforce the limit.
Skins are now limited to 256 surfaces because having no limit would
require parsing the skin file twice. The skin surfaces are dynamically
allocated so it doesn't increase memory usage when less surfaces
are used.
ArenaServers_InsertFavorites() fails to do anything because favorites
are added to the server list even if nonresponsive.
Set nonresponsive favorite server hostname to address.
When refreshing local servers, Team Arean UI never changed the status
message when it timed out. This gave a false impression it was still
looking for servers.
Let's continue looking for local servers in q3_ui and Team Arena UI
until one is found.
Restore MD3 code for cg_shadows 2 and 3 like other model formats.
Fix planar projection shadow deform (cg_shadows 3) to use correct
light direction. I fixed light direction for stencil shadows
(cg_shadows 2) but it's still broken.
Don't add the same bot to multiple teams until there are as many
bots on the server as there are bot types.
Previously each team would have unique bots until all bot types
were added to the team but other teams may have the same bot. Now
there will not be any duplicate bots until there are more bots than
bot types.
Now Quake 3 (32 bot types) in 16 vs 16 bot CTF will not contain
duplicate bot types. (You have to increase memory in code/game/
g_mem.c in order to add 32 bots though.)
I had to change G_AddRandomBot() to use 'addbot random' or else the
same bot could be added to red and blue teams. The bot was selected
and stored in console command buffer so game doesn't know not to
select the bot again.
If there are two bot infos in scripts/bots.txt then each team can
only add two random bots via bot_minplayers or addbot random.
Pick random bot info from least used bot infos instead of only ones
that are used by zero players. That way a random bot can always be
added to the game.
This rarely affected Quake 3 since there is 32 bot infos. It could
easily affect new games though.
Team Arena's Overload gametype has red and blue team Obelisk base
objects. It uses separate entities for visual and damage. Only the
damageable entity was dropped to floor. Leaving model floating off
the ground.
Team Arena's Harvester base has the same problem. Model entity
floats in air but trigger entity drops to floor.
Drop all Team Arena team base models to floor. Fixes CTF, 1Flag,
Overload, and Harvester base models.
There are various issues caused by not knowing the initial team for
the local client and bots when they connect. This is can be reproduced
by starting a team game from the main menu.
When g_teamAutoJoin is enabled, bots and local client join a random
team at connect and then execute their team command a few frames
later. This may result in the player being killed if they specify a
different team. In Team Arena's Harvester mode this causes harvester
skulls to be spawned at the beginning of the game.
When g_teamForceBalance is enabled, the local client and bots may not
be able to join their desired team. This may result in them being
spectators. If g_teamAutoJoin is also enabled they may be left on
the opposite (red/blue) team they were meant to join.
There is a hack for including bot's team in their player info string
(used by cgame for which team skin to use) before the bot joins
their desired team. Bots aren't guaranteed to join their desired team
(as may happen when both g_teamAutoJoin and g_teamForceBalance are
enabled) so clients may see them as being on the wrong team!
----
Add teampref userinfo option for team preference. If teampref is set
it will be used for attempting to join the team immediately at connect.
Bots now join team at connect using teampref userinfo. So remove
the hack for setting bot's team in player info string before the bot
joins the team.
To avoid the client sending teampref userinfo to all network servers,
the local client uses a g_localTeamPref cvar. The g_localTeamPref
cvar is cleared after it's used so it doesn't get used when starting
another server later. Another reason not to use a teampref userinfo
cvar is there isn't a reliable way to clear it in CGame/UI which are
likely loaded from baseq3 pk3.
Make it so g_teamAutoJoin doesn't affect clients who specify
teampref. If teampref is invalid, the client will join a random team
like g_teamAutoJoin.
Don't apply g_teamForceBalance to the local client or bots. Otherwise
they may be left as spectators when starting team game from menu.
The start server menus use team command and g_localTeamPref to set
the human player's team. This way it's compatible with vanilla Q3
game VMs and the new setting team at connect feature.
Bots did not notice player disconnected, so they kept attacking
the last known position.
Checking if entity is valid in BotEntityVisible might fix other
similar issues too.
This is just a simple RSA public key digital signature thing built on
libtomcrypt. The gist:
Some admin will generate a public/private key with rsa_make_keys, keeping the
private key secret. Using the private key and rsa_sign, the admin will sign
the autoupdater manifests, generating manifest.txt.sig.
The public key ships with the game (adding 270 bytes to the download), the
.sig is downloaded with the manifest by the autoupdater (256 bytes extra
download), then the autoupdater checks the manifest against the signature
with the public key. if the signature isn't valid (the manifest was tampered
with or corrupt), the autoupdater refuses to continue.
If the manifest is to be trusted, it lists sha256 checksums for every file to
download, so there's no need to sign every file; if they can't tamper with the
manifest, they can't tamper with any other file to be updated since the file's
listed sha256 won't match.
If the private key is compromised, we generate new keys and ship new
installers, so new installations will be able to update but existing ones
will need to do a new install to keep getting updates. Don't let the private
key get compromised. The private key doesn't go on a public server. Maybe it
doesn't even live on the admin's laptop hard drive.
If the download server is compromised and serving malware, the autoupdater
will reject it outright if they haven't compromised the private key, generated
a new manifest, and signed it with the private key.
libtomcrypt is sort of a big pile of source code, so instead of putting it
in revision control, we have a script to download it. Most things don't need
it. It lives on GitHub, so we _could_ do a git submodule, but most people
don't need it, so why waste their disk and bandwidth? That said, when compiled
you end up with a few hundred kilobytes of binary code to verify a signature
and no external dependencies, so it seems like a win.
Previously tested a mod cvar which may be wrong when multiple
mods are involved or config is reset. Let's check the server
cache's internet server count directly.
The blinking disconnect icon is drawn over lagometer in Q3.
Team Arena moved the lagometer location. Now let's draw the
disconnect icon over lagometer in Team Arena too!
"/team score" draws an oversized scoreboard in Q3. In Team Arena
it draws nothing. They probably intended to replace it with the
new .menu UI. But since it didn't happen, go ahead and use the Q3
tournament scoreboard.
- Actually use the second 'force' pass in G_Spawn when out of
available slots.
- Make G_EntitiesFree return qtrue if we can open a new slot.
(Only used when spawning Harvester skulls.)
Fixes not spawning Harvester skulls when there are no 'open freed
slots', but we have other slots available to open.
The Team Arena menu uses red team for single player but q3_ui
(and mods could) use blue. Also handle all the game types, not
just the ones used by Team Arena. Fixes FFA and Team DM.
Opening the find friend menu in the Team Arena server browser
hitches due to trying to resolve blank host names.
In UI_BuildFindPlayerList() status requests that are initial or
completed state or have timed out get reset. This means it starts
with MAX_SERVERSTATUSREQUESTS (16) blank host names. So just ignore
them in UI_GetServerStatusInfo().
The console message "1 servers listed in browser with 2 players."
would count clients multiple times when viewing favorite servers.
When viewing favorite servers in Team Arena UI, servers are added
to list before getting ping response. Each time UI checked pings
and inserted server it incremented the player count.
Filter favorite servers based on cached server info and new info
instead of only the cached info.
If cached server info is filtered out, don't add it to server list
but wait for getinfo response before marking server as invisible.
The player column in Team Arena UI lists clients and max clients
in format of "clients [maxclients]". When sorting by clients the
max clients is ignored which results in player column being
disorganized.
When servers have the same number of clients, sort based on max
clients. Otherwise client sort is sub-sorted based on order of
getinfo responses (ping).
Having to manually request the list, with two buttons (get new
list, refresh list) is somewhat confusing. Also since it looks
like there are no servers, users might not try to figure out
how to get the server list.
The first time viewing a master server list in Team Arena UI,
automatically request a new server list. After that the cache
will be available with a timestamp of the last refresh time.
I think this will make it easier to understand how the menu
works.
This may cause unneeded updating of the server cache because the
last refresh timestamp is per-fs_game but the server cache is
shared by all games. This will only occur once for each game
though so it's not a big concern.
Lots of Linux distros have different names (libcurl-gnutls.so vs etc), and
version the symbols (curl_global_init@@CURL_LIBSSL_3), so it's more compatible
to just dlsym the basic entry points we need and just demand that libcurl is
installed at all.
Alternately: we'll use our own libcurl build, but we'll probably have to dump
SSL support to make this sane to do.
Resolve master server addresses every 24 hours instead of keeping
result forever. Don't clear sv_master[1-5] cvar if the address fails
to resolve; it might work later.
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.

- Check com_fullyInitialized in Com_Error before removing PID,

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.
