Variables

mixed $collection_id (line 67)

The ID of the collection containing this path, or of this path if it is a collection

mixed $collection_path (line 72)

The path corresponding to the collection_id

mixed $collection_type (line 78)

The type of collection being requested:

calendar, schedule-inbox, schedule-outbox

mixed $current_user_principal_xml (line 57)

The 'current_user_principal_xml' the DAV:current-user-principal answer. An XMLElement object with an <href> or <unauthenticated> fragment.

mixed $depth (line 45)

The depth parameter from the request headers, coerced into a valid integer: 0, 1 or DEPTH_INFINITY which is defined above. The default is set per various RFCs.

mixed $method (line 39)

The HTTP request method: PROPFIND, LOCK, REPORT, OPTIONS, etc...

mixed $options (line 29)

CalDAVPrincipal $principal (line 51)

The 'principal' (user/resource/...) which this request seeks to access

mixed $raw_post (line 34)

The raw data sent along with the request

mixed $user_agent (line 62)

Methods

Constructor CalDAVRequest (line 83)

Create a new CalDAVRequest object.

CalDAVRequest CalDAVRequest ([ $options = array()])

$options

AllowedTo (line 736)

Are we allowed to do the requested activity

void AllowedTo (string $activity)

string $activity: The activity we want to do.

DepthRegexTail (line 559)

Returns the tail of a Regex appropriate for this Depth, when appended to

void DepthRegexTail ()

DoResponse (line 830)

Utility function we call when we have a simple status-based response to return to the client. Possibly

void DoResponse (int $status, [string $message = ""], [ $content_type = "text/plain; charset=\"utf-8\""])

int $status: The HTTP status code to send.
string $message: The friendly text message to send with the response.
$content_type

FailIfLocked (line 641)

This will either (a) return false if no locks apply, or (b) return the lock_token which the request successfully included to open the lock, or: (c) respond directly to the client with the failure.

return: false (no lock) or opaquelocktoken (opened lock)

mixed FailIfLocked ()

GetDepthName (line 550)

Returns the name for this depth: 0, 1, infinity

void GetDepthName ()

GetLockDetails (line 627)

Returns the DB object associated with a lock token, or false.

void GetLockDetails (string $lock_token)

string $lock_token: The opaquelocktoken which we are looking for

GetLockRow (line 570)

Returns the locked row, either from the cache or from the database

void GetLockRow ( $lock_token, string $dav_name)

string $dav_name: The resource which we want to know the lock status for
$lock_token

IsCalendar (line 687)

Returns true if the URL referenced by this request points at a calendar collection.

void IsCalendar ()

IsCollection (line 676)

Returns true if the URL referenced by this request points at a collection.

void IsCollection ()

IsInfiniteDepth (line 718)

Returns true if the request asked for infinite depth

void IsInfiniteDepth ()

IsLocked (line 507)

Checks whether the resource is locked, returning any lock token, or false

todo: This logic does not catch all locking scenarios. For example an infinite depth request should check the permissions for all collections and resources within that. At present we only maintain permissions on a per-collection basis though.

void IsLocked ()

IsPrincipal (line 696)

Returns true if the URL referenced by this request points at a principal.

void IsPrincipal ()

IsProxyRequest (line 707)

Returns true if the URL referenced by this request is within a proxy URL

void IsProxyRequest ()

IsPublic (line 539)

Checks whether the collection is public

void IsPublic ()

setPermissions (line 427)

Permissions are controlled as follows:

if the path is '/', the request has read privileges
if the requester is an admin, the request has read/write priviliges
if there is a <user name> component which matches the logged on user then the request has read/write privileges
otherwise we query the defined relationships between users and use the minimum privileges returned from that analysis.

void setPermissions (int $user_no)

int $user_no: The current user number

SupportedPrivileges (line 867)

Return an array of what the DAV privileges are that are supported

return: The supported privileges.

array SupportedPrivileges ()

UnsupportedRequest (line 795)

Sometimes it's a perfectly formed request, but we just don't do that :-(

void UnsupportedRequest (array $unsupported)

array $unsupported: An array of the properties we don't support.

UserFromPath (line 383)

Work out the user whose calendar we are accessing, based on elements of the path.

void UserFromPath ()

ValidateLockToken (line 596)

Checks to see whether the lock token given matches one of the ones handed in with the request.

void ValidateLockToken (string $lock_token)

string $lock_token: The opaquelocktoken which we are looking for

XMLResponse (line 815)

Send an XML Response. This function will never return.

void XMLResponse (int $status, XMLElement $xmltree)

int $status: The HTTP status to respond
XMLElement $xmltree: An XMLElement tree to be rendered
