No, because it's sometimes vital to have files in open_basedir to allow acces to one specific file without the need to put it into a directory for its own. Previous Comments: ------------------------------------------------------------------------ [2004-09-21 23:50:28] lists+php at box dot cz Description: ------------ My setup: document root is: "/home/wejn/x/docs/html/". While "/home/wejn/x/docs/html/" is symlink to: "/home/wejn/x/docs1/html/". I have safe_mode enabled and open_basedir set to "/home/wejn/x/docs/html:/home/wejn/x/docs1/html". With this setup I'm unable to perform: copy("/home/wejn/x/docs/html/x", "/home/wejn/x/docs/html/y"); when "y" doesn't exist. If I touch "y" prior running the script, everything runs just fine. IMO, there is problem with symlink resolving code somewhere under php_check_specific_open_basedir(). It seems to me that more precise location of the bug is somewhere in virtual_file_ex() regarding the realpath() call. Maybe it would be better to perform open_basedir check just on dirs instead of files (in various filesystem functions)? Btw, this problem exists also in 4.3.8, which makes me think that it's there for a LONG time ... unnoticed. W. Reproduce code: --------------- // when all conditions described above are met, this fails: copy('/home/wejn/x/docs/html/x', '/home/wejn/x/docs/html/y'); Expected result: ---------------- no error. Actual result: -------------- Warning: copy() [function.copy]: open_basedir restriction in effect. File(/home/wejn/x/docs/html/y) is not within the allowed path(s): (/home/wejn/x/docs/html:/home/wejn/x/docs1/html) in /home/wejn/x/docs1/html/index.html on line 2 Warning: copy(/home/wejn/x/docs/html/y) [function.copy]: failed to open stream: Operation not permitted in /home/wejn/x/docs1/html/index.html on line 2 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30188&edit=1
