allow for binary updates on linux as on windows (-allowupdate for modified/nonsvn builds). dlightmask is now size_t, because we might as well allow that on 64bit cpus, this allows for 64 lightmaphack lights instead of 32. fix potential openal issue with source=0. added q3bsp_ignorestyles cvar to ignore rbsp styles (and reduce needed batch counts), should only be used on maps with subtle lighting changes (ones that are properly lit without toggling any lightswitches). add support for directly loading foo.bsp.gz Added prints to clarify why servers might be listed under the 'UNKNOWN' category in the master server. Attempt to show hostnames anyway, to make it a little more obvious who's responsible for those badly configured servers. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5656 fc73d0e0-1445-4013-8a0c-d673dee63da5

memory allocation
|
|
|
|
|
|
H_??? The hunk manages the entire memory block given to quake. It must be
|
|
contiguous. Memory can be allocated from either the low or high end in a
|
|
stack fashion. The only way memory is released is by resetting one of the
|
|
pointers.
|
|
|
|
Hunk allocations should be given a name, so the Hunk_Print () function
|
|
can display usage.
|
|
|
|
Hunk allocations are guaranteed to be 16 byte aligned.
|
|
|
|
The video buffers are allocated high to avoid leaving a hole underneath
|
|
server allocations when changing to a higher video mode.
|
|
|
|
|
|
Z_??? Zone memory functions used for small, dynamic allocations like text
|
|
strings from command input. There is only about 48K for it, allocated at
|
|
the very bottom of the hunk.
|
|
|
|
Cache_??? Cache memory is for objects that can be dynamically loaded and
|
|
can usefully stay persistant between levels. The size of the cache
|
|
fluctuates from level to level.
|
|
|
|
To allocate a cachable object
|
|
|
|
|
|
Temp_??? Temp memory is used for file loading and surface caching. The size
|
|
of the cache memory is adjusted so that there is a minimum of 512k remaining
|
|
for temp memory.
