X-Cart:Setting up file permissions

From X-Cart 4 Classic

General info

The exact set of file permissions would depend on whether the scripts are run in the privileged mode or non-privileged mode. The privileged mode means that scripts are run under the user who is the owner of the files while in the non-privileged mode scripts are run under a different user. This implies two different approaches to setting up file permissions:

  • In the privileged mode, permissions must be granted to the owner of the files only as the scripts run under that user. Permissions for the members of the files' group and other users must be disabled then.
  • In the non-privileged mode, permissions must be granted to the owner of the files, members of the files' group and other users who are not the owner of the file or members of the group.

On the Apache web server running on a UNIX-based operating system you can find out the current mode by running in a web browser the PHP script below. The script will display two user names: the name of the script owner who put the files to the server through FTP or SSH, and the name of the user who runs the scripts. If the two names coincide, the privileged mode is enabled; otherwise, you work in the non-privileged mode.

<?php

$processUser = posix_getpwuid(posix_geteuid());

print get_current_user() . " / " . $processUser['name'];

?>

On a UNIX-based operating system file permissions for a file are changed through the the following shell command.

chmod <permissions_code> <file_path>

The permissions_code part must be a three-digit number where each digit represents a different component of the permission set: file owner, members of the group who the file owner belongs to and other users who are not the file owner or group members. Each digit is a sum of three digits, which can be 0 (no permission), 1 (execute a file or search in a directory), 2 (write) or 4 (read). Below is a list of all available values and their meaning:

  • 0 : No permission
  • 1 : Execute/search
  • 2 : Write
  • 3 : Write and execute/search
  • 4 : Read
  • 5 : Read and execute/search
  • 6 : Read and write
  • 7 : Read, write and execute/search

For example, the permissions code 740 for a file would mean that the file owner can read, write and execute the file (7), the group members can only read the file (4) and other users can do nothing with the file (0); the permissions code 511 for a directory would mean that the file owner read the contents of the directory and search in the directory (5) while the group members and other users can only search in the directory (1).
