[Bf-committers] Accessing Files (new config locations, fopen wrapper, etc)

[Andrea Weikert]

Hi,

I've read through your documentation, a few questions still:

How are relative paths handled? I would like a way to better handle 
these than they are handled currently - I have some code for a generic 
filepath struct that I didn't have time to finish yet but it would be 
worth to look at..

The functions getSystemDir and getUserDir are added to GHOST, which adds 
a pretty nasty dependency to BLI_blenlib - have you any idea on how to 
solve this?

There are quite a few functions that need consulidation: BLI_where_am_i, 
BLI_where_is_temp, get_install_dir,  BLI_gethome_folder, 
BLI_gethome_system, BLI_gethome_user and for Windows there's also 
BLI_getInstallationDir...
In these functions you can also find the code that needs to go into the 
windows version of getSystemDir and getUSerDir.
I think that a bit of planning needs to be done how to consolidate this 
with your proposal, otherwise we'll just add more to the mess that is 
alsready there.

The last issue I have with the environment variables is that if you 
create them automatically with BLI_setenv, you will add them to any 
computer where you fun Blender for example form a usb thumbdrive even 
thought the user there might not want to have anything blender 
installed. (Unlikely I know ;) ).
I would prefer to leave a user's system untouched in this case.

I do hope we can solve these issues to be able to clean up the old 
system and user directory handling and getting to a much nicer 
installation of Blender.
