That hard, don't know, but it's what I was thinking, because most likely more reliable.
If you look at IDA, you can get where it's called (one or several times) :

COM_LoadFile
SZ_Alloc
Host_Init
Mod_LoadTextures
Mod_LoadEntities
Mod_LoadSubmodels
Mod_LoadTexinfo
Mod_LoadFaces
Mod_LoadNodes
Mod_LoadLeafs
Mod_LoadClipnodes
Mod_LoadPlanes
Mod_LoadBrushModel
Mod_LoadAliasGroup
Mod_LoadAliasSkinGroup
Mod_LoadAliasModel
Mod_LoadSpriteFrame
Mod_LoadSpriteModel
Mod_LoadLighting
Mod_LoadVisibility
Mod_LoadVertexes
Mod_LoadEdges
Mod_MakeHull0
Mod_LoadMarksurfaces
Mod_LoadSurfedges
Mod_LoadAliasFrame
Mod_LoadAliasSkin
Mod_LoadSpriteGroup
SV_SpawnServer
SV_SetMaxclients
R_InitTextures

Though, if we could know easily figuring out what the server really needs would save time.

What about changing the way engine handles the alloc?

For example:

Hook this, change "option" and then call original char *COM_LoadFile(char *filename, int option, int *something) Where option = 1 => Hunk_AllocName option = 2 => Hunk_TempAlloc // This one seems to be useful for not needed resources option = 3 => Cache_Alloc option = 4 => Hunk_TempAlloc (if loadsize is not enough) option = 5 => Mem_Malloc other => Sys_Error

It would be nice to have variable hunk size, but:

I see your point.

About variable hunk size.
I see some behaviour when Hunk_AllocName is called. Some sprites has the same size each with other and some not.
Also the biggest sizes belongs to map, baselines and edicts (both can't be touched). There's something with a NULL name..

My questions:

1- What is that NULL section?

2- If something inside a map should be not loaded, isn't better to hook Mod_Load* to avoid that? (maybe I misunderstand the way you do the thing)

3- What are those sprites after the map? Can't be blocked to load? (I've tried to allocate them using Hunk_TempAlloc with luck)

Here's what de_chateau loads (summarized sizes for each Hunk_AllocName call and total accumulated size)

Yes, that would be much more elegant way to do it. But also harder, it would be a pain in the ass to hook all these functions. In my dirtier approach i have everything in one place so I can easily decide what to keep and what to drop. But you're right, it's wrong to alloc stuff and write data into it just for freeing it afterwards.

Originally Posted by joropito 3- What are those sprites after the map? Can't be blocked to load?

These are allocated by precache_model function. And these precaches are called from mp.dll from function W_Precache. Avoiding call of that function causes precache errors (message in meaning "stuff can be loaded only in precache, not now").

Do you think if I can change how the thing works and just allocate the size requested (not restricted with chunk sizes) and deallocate the unneeded segments will be better?

I know how to do that.
