C11 _Noreturn is only accepted on function declarations, not on function
pointers, so we can't use it on callbacks like game_import_t.error and
refimport_t.Sys_Error. Use a separate macro for those.
The problematic situation doesn't currently happen because the Makefile
hard-codes -std=gnu99, which disables C11 features; but removing
-std=gnu99 (resulting in the compiler's default, currently gnu11) causes
compilation failures with at least gcc 9.x.

Until now CFGDIR was hardcoded to YamagiQ2 on Windows and .yq2 on
everything else. Sometimes it's desireable to have a separate dir
for some tasks, for example whentesting things that introduce new
cvars. Add -cfgdir to override CFGDIR.
This allows for longer arguments passed to cvars, gl_nolerp_list is a
good example for a case were a token length of 128 is too short. Keep
the mapname[] buffer in the server struct at 128 bytes to preserve
savegame compatibility.
Closes#526.
cvar operations are special commands that allow the programmatic
manipulation of cvar values. 'reset' resets a given cvar to it's
default value, e.g. `reset r_mode' would reset `r_mode` to `4`.
'resetall' resets all known cvar with the exception of `game`.
The code is based upon q2pro.
This is part of issue #414.
introduced FS_GetFilenameForHandle(fileHandle_t) for this
this helps if a map has been started with "wrong" case, which doesn't
immediately fail if it has been loaded from a pack, but will result
in invalid savegame names that (with case-sensitive FSs) will fail to
load (when going back to a formerly played level)
Until now the UDP download code prohibited downloading of maps from all
pak files. That was some kind of copy protection, without the limitation
demo users could download assets from the full version. Don't apply that
protection for all paks, but only for numbered .pak files.
This could be enhanced by limiting the protection to pak0 to pak2 for
baseq2 and pak0 for both xatrix and rogue.
These are:
- CL_ResetPrecacheCheck(): Resets the precacher, forces it to reevaluate
which assets are available and what needs to be downloaded.
- FS_FileInGamedir(): Checks if a file (and only a real file, not
somthing in a pak) is available in fs_gamedir.
- FS_AddPAKFromGamedir(): Adds a pak in fs_gamedir to the search path.
Until now the server just called remove() to delete the servers state
from the HDD. That was fine on Linux were UTF-8 is used but failed
silently on Windows in case that the working dir path had some Unicode
characters. Replace remove() by Sys_Remove(), on Linux it's just a
wrapper around remove() on Windows it does a UTF8->UTF-16 conversion
and calls _wremove(). This fixes issue 318.
The 'game' command was more or less functional after the last commit.
We just need to reset the initialGame (renamed to userGivenGame) so we
don't revert back to the old game at server disconnect.
When connecting to a multiplayer game that runs a different mod
("game" cvar) than you are, it didn't load the corresponging configs
from the mod, but saved your changes to the config to the mod's config.
Which is doubly useless.
Now when the "game" cvar is changed, the configs are reloaded (from
the right directories for the mod), and when disconnecting the configs
are written, so the changes you did for a mod while playing MP are saved
before game is reset to the game you started with.
We can't rely on the game.dll being unicode conformant. Work around
that by changing the current working directory before calling into
the game.dll, pass a non unicode string to it and chang back after
we return.
To be able to pass UTF-8 encoded pathes through cvars both the cvar
subsystem and the command parser would need a fair amount of UTF-8
understanding. And I'm not the poor soul that's going to implement
that. Therefor pass the datadir trough a global variable.
This is done in shared.c so that's available for both the client /
server / renderer and the game. A work around for older game DLL will
be added at a later time.
On Unix platforms unicode is implemented through UTF-8 which is
transparent for applications. But on Windows a UTF-16 dialect is
used which needs alteration at application side. This wrapper is
another step to unicode support on Windows, now we can replace
fopen() by a function that converts our internal UTF-8 pathes to
Windows UTF-16 dialect.
This is a noop for Unix platforms. The Windows build is broken,
the compiler errors out in shared.h. This will be fixed in a
later commit.
Caveats:
* fopen() calls in 3rd party code (std_* and unzip) are not replaced.
This may become a problem. We need to check that.
* In the Unix specific code fopen() isn't replaced since it's not
necessayry.
* Remove a bunch of unnecessary functions.
* Reorder functions into logical groups. The orderig is now the same
on Unix and Windows.
While at it add several TODOs to the code. There's not need for special
library loading functions for the game, the Windows backend still uses
a lot of old and fishy DOS functions, etc. All this will be done at a
later time.
