Methods

Constructor __construct (line 105)

Create a new CalDAVRequest object.

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

$options

AllowedTo (line 943)

Are we allowed to do the requested activity

void AllowedTo (string $activity)

string $activity: The activity we want to do.

BuildSupportedPrivileges (line 905)

Returns the array of supported privileges converted into XMLElements

void BuildSupportedPrivileges ( &$reply, [ $privs = null])

&$reply
$privs

CollectionId (line 897)

Returns the ID of the collection of, or containing this request

void CollectionId ()

dav_name (line 704)

Returns the dav_name of the resource in our internal namespace

void dav_name ()

DepthRegexTail (line 722)

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

void DepthRegexTail ()

DoResponse (line 1120)

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 803)

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 713)

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

void GetDepthName ()

GetLockDetails (line 789)

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 733)

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

HavePrivilegeTo (line 1016)

Is the user has the privileges to do what is requested.

void HavePrivilegeTo ( $do_what)

$do_what

IsAddressBook (line 858)

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

void IsAddressBook ()

IsCalendar (line 849)

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

void IsCalendar ()

IsCollection (line 838)

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

void IsCollection ()

IsInfiniteDepth (line 889)

Returns true if the request asked for infinite depth

void IsInfiniteDepth ()

IsLocked (line 656)

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 867)

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

void IsPrincipal ()

IsProxyRequest (line 878)

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

void MalformedRequest ([string $text = 'Bad request'])

string $text: An optional text description of the failure.

NeedPrivilege (line 1052)

Send a need-privileges error response. This function will only return if the $href is not supplied and the current user has the specified permission for the request path.

void NeedPrivilege ( $privileges, [string $href = null], string $privilege)

string $privilege: The name of the needed privilege.
string $href: The unconstructed URI where we needed the privilege.
$privileges

PreconditionFailed (line 1077)

string $precondition: The namespaced precondition tag.
string $explanation: An optional text explanation for the failure.

Privileges (line 1008)

Return the privileges bits for the current session user to this resource

void Privileges ()

setPermissions (line 588)

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

UnsupportedRequest (line 1029)

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