CalDAVPrincipal $principal (line 51)

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

mixed $privileges (line 89)

The decimal privileges allowed by this user to the identified resource.

- access: protected

mixed $raw_post (line 34)

The raw data sent along with the request

mixed $supported_privileges (line 94)

A static structure of supported privileges.

Methods
Constructor __construct (line 99)

Create a new CalDAVRequest object.

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

- $options

AllowedTo (line 901)

Are we allowed to do the requested activity

+------------+------------------------------------------------------+ | METHOD | PRIVILEGES | +------------+------------------------------------------------------+ | MKCALENDAR | DAV:bind | | REPORT | DAV:read or CALDAV:read-free-busy (on all referenced | | | resources) | +------------+------------------------------------------------------+

void AllowedTo (string $activity)

- string $activity: The activity we want to do.

BuildSupportedPrivileges (line 863)

Returns the array of supported privileges converted into XMLElements

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

- &$reply
- $privs

CollectionId (line 855)

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

void CollectionId ()
dav_name (line 661)

Returns the dav_name of the resource in our internal namespace

void dav_name ()
DepthRegexTail (line 679)

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

void DepthRegexTail ()
DoResponse (line 1049)

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 761)

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 670)

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

void GetDepthName ()
GetLockDetails (line 747)

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 690)

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 974)

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

void HavePrivilegeTo ( $do_what)

- $do_what

IsAddressBook (line 816)

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

void IsAddressBook ()
IsCalendar (line 807)

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

void IsCalendar ()
IsCollection (line 796)

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

void IsCollection ()
IsInfiniteDepth (line 847)

Returns true if the request asked for infinite depth

void IsInfiniteDepth ()
IsLocked (line 618)

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 825)

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

void IsPrincipal ()
IsProxyRequest (line 836)

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

void IsProxyRequest ()
IsPublic (line 650)

Checks whether the collection is public

void IsPublic ()
NeedPrivilege (line 1010)

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

Privileges (line 966)

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

void Privileges ()
setPermissions (line 558)

Permissions are controlled as follows:

1. if the path is '/', the request has read privileges
2. if the requester is an admin, the request has read/write priviliges
3. if there is a <user name> component which matches the logged on user then the request has read/write privileges
4. 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 987)

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 511)

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

void UserFromPath ()
ValidateLockToken (line 716)

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 1034)

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
