- $options

AllowedTo (line 1033)

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 995)

Returns the array of supported privileges converted into XMLElements

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

- &$reply
- $privs

CheckEtagMatch (line 1109)

Check that the incoming Etag matches the one for the existing (or non-existing) resource.

- boolean $exists: Whether the destination exists
- string $dest_etag: The etag for the destination.

CoerceContentType (line 876)

Coerces the Content-type of the request into something valid/appropriate

void CoerceContentType ()

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

void CollectionId ()
dav_name (line 741)

Returns the dav_name of the resource in our internal namespace

void dav_name ()
DepthRegexTail (line 759)

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

void DepthRegexTail ([ $for_collection_report = false])

- $for_collection_report

DoResponse (line 1267)

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 841)

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 750)

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

void GetDepthName ()
GetLockDetails (line 827)

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 771)

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 1159)

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

void HavePrivilegeTo ( $do_what)

IsAddressBook (line 948)

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

IsInfiniteDepth (line 979)

Returns true if the request asked for infinite depth

void IsInfiniteDepth ()
IsLocked (line 662)

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 957)

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

void IsPrincipal ()
IsProxyRequest (line 968)

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

void PreferMinimal ()
Privileges (line 1098)

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

void Privileges ()
setPermissions (line 594)

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 1172)

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