Detailed Description

Class for an OpenStack Swift (or Ceph RGW) based file backend.

Status messages should avoid mentioning the Swift account name. Likewise, error suppression should be used to avoid path disclosure.

Since: 1.19

Definition at line 35 of file SwiftFileBackend.php.

Constructor & Destructor Documentation

SwiftFileBackend::__construct ( array $config )

See also

FileBackendStore::__construct() Additional $config params include:

swiftAuthUrl : Swift authentication server URL
swiftUser : Swift user used by MediaWiki (account:username)
swiftKey : Swift authentication key for the above user
swiftAuthTTL : Swift authentication TTL (seconds)
swiftTempUrlKey : Swift "X-Account-Meta-Temp-URL-Key" value on the account. Do not set this until it has been set in the backend.
shardViaHashLevels : Map of container names to sharding config with:
- base : base of hash characters, 16 or 36
- levels : the number of hash levels (and digits)
- repeat : hash subdirectories are prefixed with all the parent hash directory names (e.g. "a/ab/abc")
cacheAuthInfo : Whether to cache authentication tokens in APC, XCache, ect. If those are not available, then the main cache will be used. This is probably insecure in shared hosting environments.
rgwS3AccessKey : Rados Gateway S3 "access key" value on the account. Do not set this until it has been set in the backend. This is used for generating expiring pre-authenticated URLs. Only use this when using rgw and to work around http://tracker.newdream.net/issues/3454.
rgwS3SecretKey : Rados Gateway S3 "secret key" value on the account. Do not set this until it has been set in the backend. This is used for generating expiring pre-authenticated URLs. Only use this when using rgw and to work around http://tracker.newdream.net/issues/3454.

protected

Set read/write permissions for a Swift container.

See also: http://swift.openstack.org/misc.html#acls

In general, we don't allow listings to end-users. It's not useful, isn't well-defined (lists are truncated to 10000 item with no way to page), and is just a performance risk.

Parameters

string	$container	Resolved Swift container
array	$readGrps	List of the possible criteria for a request to have access to read a container. Each item is one of the following formats: account:user : Grants access if the request is by the given user ".r:<regex>" : Grants access if the request is from a referrer host that matches the expression and the request is not for a listing. Setting this to '*' effectively makes a container public. -".rlistings:<regex>" : Grants access if the request is from a referrer host that matches the expression and the request is for a listing.
array	$writeGrps	A list of the possible criteria for a request to have access to write to a container. Each item is of the following format: account:user : Grants access if the request is by the given user

Returns: Status
