Mediawiki Upload disabled when disabling php functions

Question

I have a mediaiwki installation on which upload worked perfectly. However, I disabled some php functions from php.ini for security reasons:

disable_functions = passthru,system,popen,proc_open,parse_ini_file,show_source,chdir,ini_set,ini_get,diskfreespace,disk_total_space,php_uname,posix_geteuid,exec,shell_exec,posix_getpwuid,chmod

which resulted in mediawiki upload being automatically disabled.

Does anybody know which disabled function is used for the file uploading process? I tried re-enabling popen and proc_open but they don't seem to be related.

I know I could solve it by trying to enable each function, but I thought it would be good to have such a question on SO.

chmod could couse the problem. The usual upload scripts use chmod to fix the uploaded files permissions. — Fracsi

Check mediawiki prerequisites. It could use ini_set, ini_get, chdir, parse_ini_file as well. — Fracsi

i'm sorry to say that but you should remove these functions from your forbidden list : parse_ini_file,chdir,ini_get,ini_set,chmod

to get mediawiki upload work fine
