PathRestrictions

PathRestrictions Document

This object represents the path restrictions for a storage gateway or a sharing path restrictions for a mapped collection.

The values of each of the path lists in this object are interpreted using the POSIX pattern matching notation as described in fnmatch(3) with flags set to 0 with additional support for some special user-specific value interpolation:

~, $HOME: The user’s home directory if the storage gateway supports such a concept, / otherwise
$USER: The effective Storage Gateway-specific username that is being used for data access. For a Guest Collection, this is the username of the identity that created the Guest Collection.

These restrictions are evaluated at every data access. When evaluating restrictions, the user-specific interpolation is applied before the file name matching is evaluated.

Globus Connect Server evaluates its path restrictions from longest leading expression match to shortest. When pattern matching characters are present, they are considered as a lower priority match than a literal character, with more specific pattern characters given precedence. The precedence is thus literal character, bracket expression, ? (single-character wildcard), * (wildcard).

If multiple path restrictions apply, all matches are applied from longest to shortest, with the following rules for overriding values:

Path Restriction Override Precedence

longer restriction	shorter restriction	result
read_write	read	read_write
read_write	none	read_write
read	read_write	read_write
read	none	read
none	read_write	none
none	read	none
