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.
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)
While loading a savegame the global edict arrays is free()ed and newly
malloc()ed to reset all entity states. When the game puts the first
client into the server it sends it's entity state to us, so as long as
there's only one client everything's okay. But when there're more
clients the entity states if all clients >1 are dangeling. Hack around
that by reconnecting the clients >1 entity states "manually".
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.
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.
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.
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.
Having the server in an own timing zone seems to simplify things but
introduces slight timing discrepancies. The most visible effect is that
the game runs a little bit too fast, especially in the first cl_maxfps
frames.
Therefor: Remove timeframes, they're unnecessary. Track the time since
the last (client|server) frame instead and pass it to the client and
server when it's called.
This is the same as the client does for it's realtime. It looks at least
somewhat more correct since it pevents rounding errors. And things are
simplified a litte bit since the server timing is now independent of the
global timing.
Remove all functions that are no longer used:
* FS_AddGameDirectory()
* FS_SetGameDir()
* FS_AddHomeAsGameDirectory()
* FS_AddBinaryDirAsGameDirectory()
While at it try remove as much global variables from filesystem.c as
possible. Also fix a small, longstandig bug: The download code should
treat .zip and .pk3 files as pak files and not as normal directories.
Moving the check under the "do we have the file localy" check prevents
spurious "Refusing to download a path with .." messages with some game
data. The tank commander skin is one example. This change has no
security impact since FS_LoadFile() just opens and closes the file.
While at it tighten the condition to prevent pathes with colons (this
condition is added at the server side, too) and pathes starting with
slashes and dots.
The savegame list is generated by calling FS_FOpenFile() for each
possible savegame name. When a file handle is returned the savegame
exists, otherwise the savegame slot is empty. But FS_FOpenFile()
searches in every directory known to the VFS. If a savegame file
isn't found in $moddir but in baseq2, the file in baseq2 is opened
and a baseq2 savegame is displayed in the mods / addons savegame menu.
The fix is compromise between a clean solution and invasiveness:
- Refactor FS_FOpenFile() to include FS_FOpenFileRead(). FS_FOpenFile()
was used only to open read only files, limit its's possibilities to
do exactly that.
- Introduce a new flag "gamedir_only" to FS_FOpenFile(). When true
only the gamedir directories are searched and not other directories
like baseq2.
- Change all callers to FS_FOpenFile()s new signature.
- Use the new gamedir_only flag to limit the searchpath for savegames
to the gamedir.
sounds easy, right?
Except some genius decided to save CVAR_LATCH cvars in buffers of
MAX_OSPATH length into savegames.. so just changing MAX_OSPATH
breaks savegame compatibility.
Fortunately, this assumption only matters in SV_WriteServerFile() and
SV_ReadServerFile() so I worked around it by introducing a
platform-specific LATCH_CVAR_SAVELENGTH (because MAX_OSPATH was 256 on
Windows but 128 on other systems..)
Newer jpeg versions (I guess starting with 9) define an macro
"VERSION", colliding with ours. While wie could #undef it, take
the less hacky route and rename it.
Revert "change several strcat calls to Q_strlcat calls"
This reverts commit ab879f1bc7.
Revert "change (v)sprintf calls to (v)snprintf calls"
This reverts commit b46e210d76.
This check involved an uninitialized pointer, so it never worked. It
could lead to crashes in some situations, especially when clients tried
to reconnect after a manual map change on the dedictated server.
Using a float number as version number is a bad idea. Correct this long
standing problem by changing it to a string. If we ever want to compare
version numbers, 2 integer constants "MAJOR_VERSION" and "MINOR_VERSION"
should be added.
