-QUAKE3 FILESYSTEM
-
-All of Quake's data access is through a hierarchical file system, but the contents of
-the file system can be transparently merged from several sources.
-
-A "qpath" is a reference to game file data. MAX_ZPATH is 256 characters, which must include
-a terminating zero. "..", "\\", and ":" are explicitly illegal in qpaths to prevent any
-references outside the quake directory system.
-
-The "base path" is the path to the directory holding all the game directories and usually
-the executable. It defaults to ".", but can be overridden with a "+set fs_basepath c:\quake3"
-command line to allow code debugging in a different directory. Basepath cannot
-be modified at all after startup. Any files that are created (demos, screenshots,
-etc) will be created reletive to the base path, so base path should usually be writable.
-
-The "cd path" is the path to an alternate hierarchy that will be searched if a file
-is not located in the base path. A user can do a partial install that copies some
-data to a base path created on their hard drive and leave the rest on the cd. Files
-are never writen to the cd path. It defaults to a value set by the installer, like
-"e:\quake3", but it can be overridden with "+set ds_cdpath g:\quake3".
-
-If a user runs the game directly from a CD, the base path would be on the CD. This
-should still function correctly, but all file writes will fail (harmlessly).
-
-The "home path" is the path used for all write access. On win32 systems we have "base path"
-== "home path", but on *nix systems the base installation is usually readonly, and
-"home path" points to ~/.q3a or similar
-
-The user can also install custom mods and content in "home path", so it should be searched
-along with "home path" and "cd path" for game content.
-
-
-The "base game" is the directory under the paths where data comes from by default, and
-can be either "baseq3" or "demoq3".
-
-The "current game" may be the same as the base game, or it may be the name of another
-directory under the paths that should be searched for files before looking in the base game.
-This is the basis for addons.
-
-Clients automatically set the game directory after receiving a gamestate from a server,
-so only servers need to worry about +set fs_game.
-
-No other directories outside of the base game and current game will ever be referenced by
-filesystem functions.
-
-To save disk space and speed loading, directory trees can be collapsed into zip files.
-The files use a ".pk3" extension to prevent users from unzipping them accidentally, but
-otherwise the are simply normal uncompressed zip files. A game directory can have multiple
-zip files of the form "pak0.pk3", "pak1.pk3", etc. Zip files are searched in decending order
-from the highest number to the lowest, and will always take precedence over the filesystem.
-This allows a pk3 distributed as a patch to override all existing data.
-
-Because we will have updated executables freely available online, there is no point to
-trying to restrict demo / oem versions of the game with code changes. Demo / oem versions
-should be exactly the same executables as release versions, but with different data that
-automatically restricts where game media can come from to prevent add-ons from working.
-
-After the paths are initialized, quake will look for the product.txt file. If not
-found and verified, the game will run in restricted mode. In restricted mode, only
-files contained in demoq3/pak0.pk3 will be available for loading, and only if the zip header is
-verified to not have been modified. A single exception is made for q3config.cfg. Files
-can still be written out in restricted mode, so screenshots and demos are allowed.
-Restricted mode can be tested by setting "+set fs_restrict 1" on the command line, even
-if there is a valid product.txt under the basepath or cdpath.
-
-If not running in restricted mode, and a file is not found in any local filesystem,
-an attempt will be made to download it and save it under the base path.
-
-If the "fs_copyfiles" cvar is set to 1, then every time a file is sourced from the cd
-path, it will be copied over to the base path. This is a development aid to help build
-test releases and to copy working sets over slow network links.
-
-File search order: when FS_FOpenFileRead gets called it will go through the fs_searchpaths
-structure and stop on the first successful hit. fs_searchpaths is built with successive
-calls to FS_AddGameDirectory
-
-Additionaly, we search in several subdirectories:
-current game is the current mode
-base game is a variable to allow mods based on other mods
-(such as baseq3 + missionpack content combination in a mod for instance)
-BASEGAME is the hardcoded base game ("baseq3")
-
-e.g. the qpath "sound/newstuff/test.wav" would be searched for in the following places:
-
-home path + current game's zip files
-home path + current game's directory
-base path + current game's zip files
-base path + current game's directory
-cd path + current game's zip files
-cd path + current game's directory
-
-home path + base game's zip file
-home path + base game's directory
-base path + base game's zip file
-base path + base game's directory
-cd path + base game's zip file
-cd path + base game's directory
-
-home path + BASEGAME's zip file
-home path + BASEGAME's directory
-base path + BASEGAME's zip file
-base path + BASEGAME's directory
-cd path + BASEGAME's zip file
-cd path + BASEGAME's directory
-
-server download, to be written to home path + current game's directory
-
-
-The filesystem can be safely shutdown and reinitialized with different
-basedir / cddir / game combinations, but all other subsystems that rely on it
-(sound, video) must also be forced to restart.
-
-Because the same files are loaded by both the clip model (CM_) and renderer (TR_)
-subsystems, a simple single-file caching scheme is used. The CM_ subsystems will
-load the file with a request to cache. Only one file will be kept cached at a time,
-so any models that are going to be referenced by both subsystems should alternate
-between the CM_ load function and the ref load function.
-
-TODO: A qpath that starts with a leading slash will always refer to the base game, even if another
-game is currently active. This allows character models, skins, and sounds to be downloaded
-to a common directory no matter which game is active.
-
-How to prevent downloading zip files?
-Pass pk3 file names in systeminfo, and download before FS_Restart()?
-
-Aborting a download disconnects the client from the server.
-
-How to mark files as downloadable? Commercial add-ons won't be downloadable.
-
-Non-commercial downloads will want to download the entire zip file.
-the game would have to be reset to actually read the zip in
-
-Auto-update information
-
-Path separators
-
-Casing
-
- separate server gamedir and client gamedir, so if the user starts
- a local game after having connected to a network game, it won't stick
- with the network game.
-
- allow menu options for game selection?
-
-Read / write config to floppy option.
-
-Different version coexistance?
-
-When building a pak file, make sure a q3config.cfg isn't present in it,
-or configs will never get loaded from disk!
-
- todo:
-
- downloading (outside fs?)
- game directory passing and restarting

MAX_ZPATH is 256 characters, which must include +a terminating zero. "..", "\\", and ":" are explicitly illegal in qpaths to prevent any +references outside the quake directory system. + +The "base path" is the path to the directory holding all the game directories and usually +the executable. It defaults to ".", but can be overridden with a "+set fs_basepath c:\quake3" +command line to allow code debugging in a different directory. Basepath cannot +be modified at all after startup. Any files that are created (demos, screenshots, +etc) will be created reletive to the base path, so base path should usually be writable. + +The "cd path" is the path to an alternate hierarchy that will be searched if a file +is not located in the base path. A user can do a partial install that copies some +data to a base path created on their hard drive and leave the rest on the cd. Files +are never writen to the cd path. It defaults to a value set by the installer, like +"e:\quake3", but it can be overridden with "+set ds_cdpath g:\quake3". + +If a user runs the game directly from a CD, the base path would be on the CD. This +should still function correctly, but all file writes will fail (harmlessly). + +The "home path" is the path used for all write access. On win32 systems we have "base path" +== "home path", but on *nix systems the base installation is usually readonly, and +"home path" points to ~/.q3a or similar + +The user can also install custom mods and content in "home path", so it should be searched +along with "home path" and "cd path" for game content. + + +The "base game" is the directory under the paths where data comes from by default, and +can be either "baseq3" or "demoq3". + +The "current game" may be the same as the base game, or it may be the name of another +directory under the paths that should be searched for files before looking in the base game. +This is the basis for addons. + +Clients automatically set the game directory after receiving a gamestate from a server, +so only servers need to worry about +set fs_game. + +No other directories outside of the base game and current game will ever be referenced by +filesystem functions. + +To save disk space and speed loading, directory trees can be collapsed into zip files. +The files use a ".pk3" extension to prevent users from unzipping them accidentally, but +otherwise the are simply normal uncompressed zip files. A game directory can have multiple +zip files of the form "pak0.pk3", "pak1.pk3", etc. Zip files are searched in decending order +from the highest number to the lowest, and will always take precedence over the filesystem. +This allows a pk3 distributed as a patch to override all existing data. + +Because we will have updated executables freely available online, there is no point to +trying to restrict demo / oem versions of the game with code changes. Demo / oem versions +should be exactly the same executables as release versions, but with different data that +automatically restricts where game media can come from to prevent add-ons from working. + +After the paths are initialized, quake will look for the product.txt file. If not +found and verified, the game will run in restricted mode. In restricted mode, only +files contained in demoq3/pak0.pk3 will be available for loading, and only if the zip header is +verified to not have been modified. A single exception is made for q3config.cfg. Files +can still be written out in restricted mode, so screenshots and demos are allowed. +Restricted mode can be tested by setting "+set fs_restrict 1" on the command line, even +if there is a valid product.txt under the basepath or cdpath. + +If not running in restricted mode, and a file is not found in any local filesystem, +an attempt will be made to download it and save it under the base path. + +If the "fs_copyfiles" cvar is set to 1, then every time a file is sourced from the cd +path, it will be copied over to the base path. This is a development aid to help build +test releases and to copy working sets over slow network links. + +File search order: when FS_FOpenFileRead gets called it will go through the fs_searchpaths +structure and stop on the first successful hit. fs_searchpaths is built with successive +calls to FS_AddGameDirectory + +Additionaly, we search in several subdirectories: +current game is the current mode +base game is a variable to allow mods based on other mods +(such as baseq3 + missionpack content combination in a mod for instance) +BASEGAME is the hardcoded base game ("baseq3") + +e.g. the qpath "sound/newstuff/test.wav" would be searched for in the following places: + +home path + current game's zip files +home path + current game's directory +base path + current game's zip files +base path + current game's directory +cd path + current game's zip files +cd path + current game's directory + +home path + base game's zip file +home path + base game's directory +base path + base game's zip file +base path + base game's directory +cd path + base game's zip file +cd path + base game's directory + +home path + BASEGAME's zip file +home path + BASEGAME's directory +base path + BASEGAME's zip file +base path + BASEGAME's directory +cd path + BASEGAME's zip file +cd path + BASEGAME's directory + +server download, to be written to home path + current game's directory + + +The filesystem can be safely shutdown and reinitialized with different +basedir / cddir / game combinations, but all other subsystems that rely on it +(sound, video) must also be forced to restart. + +Because the same files are loaded by both the clip model (CM_) and renderer (TR_) +subsystems, a simple single-file caching scheme is used. The CM_ subsystems will +load the file with a request to cache. Only one file will be kept cached at a time, +so any models that are going to be referenced by both subsystems should alternate +between the CM_ load function and the ref load function. + +TODO: A qpath that starts with a leading slash will always refer to the base game, even if another +game is currently active. This allows character models, skins, and sounds to be downloaded +to a common directory no matter which game is active. + +How to prevent downloading zip files? +Pass pk3 file names in systeminfo, and download before FS_Restart()? + +Aborting a download disconnects the client from the server. + +How to mark files as downloadable?
